First Trust Enhanced Short Maturity ETF (the “Fund”) lists and principally trades its shares on The Nasdaq Stock Market LLC ("Nasdaq" or the "Exchange"). Market prices may differ to some degree from the net asset value of the shares. Unlike mutual funds, the Fund issues and redeems shares at net asset value, only in large specified blocks of shares called "Creation Units."

The Fund is a series of First Trust Exchange-Traded Fund IV (the “Trust”) and an actively managed exchange-traded fund organized as a separate series of a registered management investment company.

Except when aggregated in Creation Units, the shares are not redeemable securities of the Fund.

The Securities and Exchange Commission has not approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Trust’s Board of Trustees or (ii) upon the termination of the Fund’s management agreement with the Fund’s investment advisor, however, it is expected to remain in place for no less than one year from the date of this prospectus.

(3)

Fee Waiver has been restated to reflect the current fiscal year.

Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account customary brokerage commissions that you pay when purchasing or selling shares of the Fund in the secondary market.

The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels until March 1, 2022 and at 0.45% thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$26	$124	$232	$547

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 73% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund intends to achieve its investment objective by investing at least 80% of its net assets in a portfolio of U.S. dollar-denominated fixed- and variable-rate debt securities, including securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities, residential and commercial mortgage-backed securities, asset-backed securities, U.S. corporate bonds, fixed income securities issued by non-U.S. corporations and governments, municipal obligations, privately issued securities and other debt securities bearing fixed or floating interest rates. The Fund may also invest in money market securities.

The Fund’s investment advisor selects securities for the portfolio by evaluating fixed income sectors and macro market trends while completing bottom-up analysis of individual securities. Portfolio securities are selected based upon relative value in the context of overall portfolio duration. Key inputs for the screens in the securities selection process include, but are not limited to, credit quality, yield, interest rate sensitivity and liquidity. The Fund’s holdings are systematically monitored for meaningful changes in performance and risk measures. A security will generally be sold when the Fund’s investment advisor believes that a security can be substituted for a similar investment that represents better relative value; it lacks adequate compensation for embedded credit risk; or when rebalancing the portfolio to maintain diversification.

At least 80% of the Fund’s net assets will be invested in debt securities that are, at the time of purchase, investment grade. For an unrated security to be considered investment grade, the Fund’s investment advisor will consider, at the time of purchase, whether such security is of comparable quality based on fundamental credit analysis of the unrated security and comparable securities that are rated by a nationally recognized statistical rating organization (“NRSRO”).

Under normal market conditions, the Fund’s portfolio is expected to have an average duration of less than one year and an average maturity of less than three years. Maturity is measured differently depending on the type of debt security. For asset-backed securities and mortgage-related securities, maturity is calculated using weighted average life, which is the estimated time to principal paydown for each underlying instrument held by the Fund, weighted according to the relative holdings per instrument. For all other debt securities, maturity is calculated using dollar-weighted average maturity, which is the average length of time to maturity. Duration is a measure of the expected price volatility of a debt instrument as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments, call features and coupon adjustments in addition to the amount of time until the security finally matures. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, if a portfolio of debt securities has an average duration of three years, its value can be expected to fall about 3% if interest rates rise by 1%. Conversely, the portfolio’s value can be expected to rise about 3% if interest rates fall by 1%. As a result, prices of instruments with shorter durations tend to be less sensitive to interest rate changes than instruments with longer durations. As the value of a security changes over time, so will its duration.

The Fund may invest in asset-backed securities and mortgage-related securities. Asset-backed securities are fixed income securities that are backed by a pool of assets, usually loans such as installment sale contracts or credit card receivables. Mortgage-related securities are asset-backed securities based on a particular type of asset, a mortgage. There are a wide variety of mortgage-related securities involving commercial or residential, fixed rate or adjustable rate mortgages and mortgages issued by banks or government agencies. The Fund intends to limit its investments in privately-issued, non-agency sponsored mortgage- and asset-backed securities to 20% of its net assets.

The Fund may invest up to 20% of its net assets in floating rate loans representing amounts borrowed by companies or other entities from banks and other lenders. A significant portion of these loans may be rated below investment grade or unrated. Floating rate loans held by the Fund may be senior or subordinate obligations of the borrower and may or may not be secured by collateral.

The Fund may invest in investment companies, such as exchange-traded funds (“ETFs”), that invest primarily in debt securities. The debt securities held by the investment companies in the Fund’s portfolio will be counted towards the requirement that the Fund invest 80% of its net assets in debt securities. The Fund may invest in ETFs that are advised by First Trust Advisors LP, the Fund’s investment advisor.

Principal Risks

the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

ASSET-BACKED SECURITIES RISK. Asset-backed securities are debt securities typically created by buying and pooling loans or other receivables other than mortgage loans and creating securities backed by those similar type assets. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. These securities are generally not backed by the full faith and credit of the U.S. government and are subject to the risk of default on the underlying asset or loan, particularly during periods of economic downturn. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CALL RISK. Some debt securities may be redeemed, or “called,” at the option of the issuer before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. The Fund would then be forced to invest the proceeds at lower interest rates, likely resulting in a decline in the Fund’s income.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

value of longer-term debt securities generally changes more in response to changes in interest rates than shorter-term debt securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

FLOATING RATE DEBT INSTRUMENTS RISK. Investments in floating rate debt instruments are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to the Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, floating rate loans may not be considered “securities” under federal securities laws, and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

INCOME RISK. The Fund’s income may decline when interest rates fall or if there are defaults in its portfolio. This decline can occur because the Fund may subsequently invest in lower-yielding securities as debt securities in its portfolio mature, are near maturity or are called, or the Fund otherwise needs to purchase additional debt securities.

INDEX CONSTITUENT RISK. The Fund may be a constituent of one or more indices. As a result, the Fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund’s shares, the size of the Fund and the market volatility of the Fund. Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, the Fund’s net asset value could be negatively impacted and the Fund’s market price may be below the Fund’s net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in the Fund’s shares.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

LIQUIDITY RISK. The Fund may hold certain investments that may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective.

MARKET MAKER RISK. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

NON-AGENCY SECURITIES RISK. Investments in asset-backed or mortgage-backed securities offered by non-governmental issuers, such as commercial banks, savings and loans, private mortgage insurance companies, mortgage bankers and other secondary market issuers are subject to additional risks. There are no direct or indirect government or agency guarantees of payments in loan pools created by non-government issuers. Securities issued by private issuers are subject to the credit risks of the issuers. An unexpectedly high rate of defaults on the loan pool may adversely affect the value of a non-agency security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of pools that include subprime loans. Non-agency securities are typically traded “over-the-counter” rather than on a securities exchange and there may be

a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, the non-agency mortgage-related securities held by the Fund may be particularly difficult to value because of the complexities involved in assessing the value of the underlying loans.

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Although the Fund and the Advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. The Fund’s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

PREPAYMENT RISK. Prepayment risk is the risk that the issuer of a debt security will repay principal prior to the scheduled maturity date. Debt securities allowing prepayment may offer less potential for gains during a period of declining interest rates, as the Fund may be required to reinvest the proceeds of any prepayment at lower interest rates. These factors may cause the value of an investment in the Fund to change.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

TRADING ISSUES RISK. Trading in Fund shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

VALUATION RISK. Unlike publicly traded securities that trade on national securities exchanges, there is no central place or exchange for trading most debt securities. Debt securities generally trade on an “over-the-counter” market. Due to the lack of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Debt securities are commonly valued by third-party pricing services that utilize a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such securities, cash flows and transactions for comparable instruments. However, because the available information is less reliable and more subjective, elements of judgment may play a greater role

Additional Information on the Fund's Investment Objective and Strategies

The Fund is a series of First Trust Exchange-Traded Fund IV and is regulated as an “investment company” under the 1940 Act. The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objective is fundamental and may not be changed without approval by the holders of a majority of the outstanding voting securities of the Fund. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. If there is a material change to the Fund’s principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.

In selecting securities for the Fund, the Advisor’s investment strategies are driven by comprehensive analysis with a goal of investing in securities representing the best relative value in the market.

Fund Investments

Principal Investments

Short-Term Investments

The Fund may invest in short-term debt securities, money market funds and other cash equivalents, or it may hold cash. The percentage of the Fund invested in such holdings will vary and will depend on several factors, including market conditions.

Short-term debt securities are securities from issuers having a long-term debt rating in one of the three highest possible categories by S&P Ratings, Moody’s or Fitch and having a maturity of one year or less. Short-term debt securities are defined to include, without limitation, the following: (i) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities; (ii) short-term securities issued or guaranteed by non-U.S. governments or by their agencies or instrumentalities; (iii) certificates of deposit issued against funds deposited in a bank or savings and loan association; (iv) bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions; (v) repurchase agreements, which involve purchases of debt securities; (vi) bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest; and (vii) commercial paper, which is short-term unsecured promissory notes. The Fund may only invest in commercial paper rated A-3 or higher by S&P Ratings, Prime-3 or higher by Moody’s or F3 or higher by Fitch.

Corporate Bonds

The Fund may invest in corporate debt securities issued by U.S. and non-U.S. companies of all kinds, including those with small, mid and large capitalizations. Corporate debt securities are fixed income securities issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary differences being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. Corporate debt may be rated investment grade or below investment grade and may carry fixed or floating rates of interest.

Mortgage-Related and Other Asset-Backed Securities

The Fund generally expects that the mortgage-related securities in which it invests will primarily consist of investment grade securities (i.e., securities with credit ratings within the four highest rating categories of a NRSRO at the time of purchase). The Fund invests in mortgage-backed securities (such as residential mortgage backed securities (“RMBS”) and commercial mortgage backed securities (“CMBS”)). Mortgage-related securities represent an interest in a pool of mortgage loans made by banks and other financial institutions to finance purchases of homes, commercial buildings and other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors. As the underlying mortgage loans are paid off, investors receive principal and interest payments. Mortgage-related securities may be fixed-rate or adjustable-rate mortgage-related securities (ARMS). Certain mortgage-related securities (including RMBS and CMBS), where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest, are referred to as stripped mortgage-related securities (SMBS). Further, mortgage-related securities can also be categorized as collateralized mortgage obligations (CMOs) or real estate mortgage investment conduits (REMICs) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets.

The mortgage-related securities in which the Fund invests may be, but are not required to be, issued or guaranteed by the U.S. government, its agencies or instrumentalities, such as Ginnie Mae and U.S. government-sponsored entities, such as Fannie Mae and Freddie Mac. Government agency or instrumentality securities have different levels of credit support. For example, Ginnie Mae securities carry a guarantee as to the timely repayment of principal and interest that is backed by the full faith and credit of the U.S. government. However, the full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. Fannie Mae and Freddie Mac pass-through mortgage certificates are backed by the credit of the respective instrumentality and are not guaranteed by the U.S. government. Other securities issued by government agencies or instrumentalities, including government-sponsored entities, may only be backed by the creditworthiness of the issuing institution, not the U.S. government, or the issuers may have the right to borrow from the U.S. Treasury to meet their obligations. Many mortgage-related securities are pass-through securities, which means they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately. Adjustable-rate mortgage-related securities include ARMS and other mortgage-related securities with interest rates that adjust periodically to reflect prevailing market rates.

Asset-backed securities are similar to mortgage-related securities, except that the securities backing them are assets such as loans, leases, credit card debt, a company’s receivables or royalties, and not mortgage-related securities.

Government Bonds

International Sovereign Debt

The Fund may invest in debt securities, including inflation-linked bonds, issued by foreign governments or their subdivisions, agencies and government-sponsored enterprises. Sovereign Debt may include bonds, notes or other debt obligations denominated in U.S. dollars issued by foreign governments.

Investment Companies

As a principal investment strategy, the Fund may invest in securities of investment companies, including ETFs, some of which may be advised by the Advisor. The Fund may invest in such investment companies to gain exposure to certain Fixed Income Securities including high yield bonds, floating rate loans, corporate bonds, municipal securities, mortgage- related instruments and government bonds.

If the Fund invests in any investment companies that are advised by the Advisor, the Fund will “look through” the investment company to maintain its investment requirements with respect to investment grade ratings, duration and maturity. For the purpose of fulfilling the requirement that 80% of the Fund’s net assets be invested in investment grade securities, the Fund will use the ratings of the Fixed Income Securities held by the Fund and held by the investment companies in which the Fund invests. The Fund’s duration shall be calculated by using the duration of the Fixed Income Securities that the Fund holds directly and indirectly through its investment in investment companies. The maturity of the Fund’s holdings shall be calculated by using the maturity of the Fixed Income Securities that the Fund holds directly and indirectly through its investment in investment companies. The Fund will disregard the equity securities that any investment company may hold for purposes of calculating duration and maturity. The Fund has adopted a policy such that any investment company in which it invests will hold no more than 5% of its net assets in equity securities. If the Fund invests in any investment companies that are not advised by the Advisor, the Fund will consider the investment company’s investment policies to maintain its investment requirements with respect to investment grade ratings, duration and maturity.

The Fund’s ability to invest in other investment companies is limited by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act. ETFs trade on a securities exchange and their shares may, at times, trade at a premium or discount to their net asset value.

In general, as a shareholder of an investment company, the Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the fund’s advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. However, pursuant to a contractual agreement, the Advisor has agreed to reduce the management fee paid by the Fund by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided, that, the investment companies are advised by the Advisor. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed- end investment companies.

High Yield Corporate Bonds and Floating Rate Loans

The Fund may invest in a combination of high yield corporate bonds and floating rate loans. The high yield corporate bonds in which the Fund invests are rated below investment grade at the time of purchase or unrated and deemed by the Advisor to be of comparable quality, commonly referred to as “junk” bonds. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. High yield debt may be issued, for example, by companies without long track records of sales and earnings or by issuers that have questionable credit strength. Corporate bonds may carry fixed or floating rates of interest.

The floating rate loans in which the Fund invests represent amounts borrowed by companies or other entities from banks and other lenders. In many cases, floating rate loans are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancing. A significant portion of the floating rate loans in which the Fund invests are expected to be rated below investment grade or unrated. The floating rate loans held by the Fund may be senior or subordinate obligations of the borrower. In the event of bankruptcy, holders of senior floating rate loans are typically paid (to the extent assets are available) before certain other creditors of the borrower (e.g., bondholders and stockholders). Holders of subordinate loans may be paid after more senior bondholders. Loans may or may not be secured by collateral.

Floating rate loans have interest rates that reset periodically. The interest rates on floating rate loans are generally based on a percentage above the London Interbank Offered Rate (LIBOR), a U.S. bank’s prime or base rate, the overnight federal funds rate, or another rate. Floating rate loans may be structured and administered by a financial institution that acts as the agent of the lenders participating in the floating rate loan. The Fund may acquire floating rate loans directly from a lender or through the agent, as an assignment from another lender who holds a floating rate loan, or as a participation interest in another lender’s floating rate loan or portion thereof. The Advisor does not intend to purchase floating rate loans that are in default; however, the Fund may hold a floating rate loan that has defaulted subsequent to the purchase by the Fund.

Municipal Securities

Municipal securities are debt securities that pay interest that is exempt from regular federal income taxes. Municipal securities are generally issued by or on behalf of states, territories or possessions of the United States and the District of Columbia and their political subdivisions, agencies, authorities and other instrumentalities. The types of municipal securities in which the Fund may invest include municipal lease obligations (and certificates of participation in such obligations), municipal general obligation bonds, municipal revenue bonds, municipal notes, municipal cash equivalents, private activity bonds (including without limitation industrial development bonds), and pre-refunded and escrowed to maturity bonds. In addition, municipal securities include securities issued by entities whose underlying assets are municipal bonds (for example, tender option bond (TOB) trusts and custodial receipts trusts).

Non-Principal Investments

Illiquid Securities

The Fund may invest up to 15% of its net assets in securities and other instruments that are, at the time of investment, illiquid (determined using the Securities and Exchange Commission's standard applicable to investment companies, i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For this purpose, illiquid securities may include, but are not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), that are deemed to be illiquid, and certain repurchase agreements.

Disclosure of Portfolio Holdings

The Fund's portfolio holdings are available on the Fund's website at www.ftportfolios.com. A description of the policies and procedures with respect to the disclosure of the Fund’s portfolio securities is included in the Fund’s SAI, which is also available on the Fund’s website.

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objective. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

ASSET-BACKED SECURITIES RISK. Asset-backed securities are debt securities typically created by buying and pooling loans or other receivables other than mortgage loans and creating securities backed by those similar type assets. They are typically issued by trusts and special purpose co-purchasers that pass income from the underlying pool to investors. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. Certain asset-backed securities do not have the benefit of the same security interest in the related collateral as do mortgage-backed securities, nor are they provided government guarantees of repayment. Credit card receivables are generally unsecured, and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. In addition, some issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CALL RISK. Some debt securities may be redeemed at the option of the issuer, or “called,” before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. The Fund would then be forced to invest the unanticipated proceeds at lower interest rates, likely resulting in a decline in the Fund’s income. Such redemptions and subsequent reinvestments would also increase the Fund’s portfolio turnover. If a called debt security was purchased by the Fund at a premium, the value of the premium may be lost in the event of a redemption.

CASH TRANSACTIONS RISK. The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. The Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments. Debt securities are subject to varying degrees of credit risk which are often reflected in credit ratings. The credit rating of a debt security may be lowered if the issuer or other obligated party suffers adverse changes to its financial condition. These adverse changes may lead to greater volatility in the price of the debt security and affect the security’s liquidity. High yield and comparable unrated debt securities, while generally offering higher yields than investment grade debt with similar maturities, involve greater risks, including the possibility of dividend or interest deferral, default or bankruptcy, and are regarded as predominantly speculative with respect to the issuer’s capacity to pay dividends or interest and repay principal. To the extent that the Fund holds debt securities that are secured or guaranteed by financial institutions, changes in credit quality of such financial institutions could cause values of the debt security to deviate.

CYBER SECURITY RISK. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. These risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Advisor, distributor and other service providers (including, but not limited to, sub-advisors, index providers, fund accountants, custodians, transfer agents and administrators), market makers, authorized participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses; interference with the Fund’s ability to calculate its net asset value; disclosure of confidential trading information; impediments to trading; submission of erroneous trades or erroneous creation or redemption orders; the inability of the Fund or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines penalties, reputational damage, reimbursement or other compensation costs; or additional compliance costs. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. However, there is no guarantee that such efforts will succeed, and the Fund and its shareholders could be negatively impacted as a result.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

EXTENSION RISK. Extension risk is the risk that, when interest rates rise, certain obligations will be paid off by the issuer (or other obligated party) more slowly than anticipated, causing the value of these debt securities to fall. Rising interest rates tend to extend the duration of debt securities, making them more sensitive to changes in interest rates. The value of longer-term debt securities generally changes more in response to changes in interest rates than shorter-term debt securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value. Extension risk is particularly prevalent for a callable debt security where an increase in interest rates could result in the issuer of that security choosing not to redeem the debt security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value.

FLOATING RATE DEBT INSTRUMENTS RISK. Investments in floating rate debt instruments are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. The Fund may invest in floating rate loans considered to be high yield, or “junk,” instruments and considered speculative because of the credit risk of their issuers. Such issuers are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund. An economic downturn would also generally lead to a higher non-payment rate, and a floating rate debt instrument may lose significant market value before a default occurs. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods which may cause the Fund to be unable to realize the full value of its investment. Lastly, floating rate loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

INCOME RISK. The Fund’s income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding securities as debt securities in its portfolio mature, are near maturity or are called, or the Fund otherwise needs to purchase additional debt securities. In addition, the Fund’s income could decline when the Fund experiences defaults on the debt securities it holds.

INDEX CONSTITUENT RISK. The Fund may be a constituent of one or more indices or ETF models. As a result, the Fund may be included in one or more index-tracking ETFs or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund, the size of the Fund and the market volatility of the Fund’s shares. Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, the Fund’s net asset value could be negatively impacted and the Fund’s market price may be below the Fund’s net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity. To the extent buying or selling activity increases, the Fund can be exposed to increased brokerage costs and adverse tax consequences and the market price of the Fund can be negatively affected.

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to debt securities held by the Fund. Inflation creates uncertainty over the future real value (after inflation) of an investment. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund investors.

INTEREST RATE RISK. The value of debt securities held by the Fund will fluctuate in value with changes in interest rates. In general, debt securities will increase in value when interest rates fall and decrease in value when interest rates rise. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Interest rate risk is generally lower for shorter term investments and higher for longer term investments. Duration is a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of a debt security, the greater the debt security’s price sensitivity is to changes in interest rates. Rising interest rates also may lengthen the duration of debt securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. An increase in interest rates could also cause principal payments on a debt security to be repaid at a slower rate than expected. This risk

is particularly prevalent for a callable debt security where an increase in interest rates could cause the issuer of that security to not redeem the security as anticipated on the call date, effectively lengthening the security’s expected maturity, in turn making that security more vulnerable to interest rate risk and reducing its market value. When interest rates fall, the Fund may be required to reinvest the proceeds from the sale, redemption or early prepayment of a debt security at a lower interest rate.

LIBOR RISK. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, intends to cease making LIBOR available as a reference rate over a phase-out period that is currently expected to begin after the end of 2021, although the specific timing of the phase out of LIBOR continues to be discussed and negotiated across the industry and in various jurisdictions. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the Fund or on certain instruments in which the Fund invests can be difficult to ascertain, and they may vary depending on a variety of factors. For example, certain of the Fund’s investments may involve individual contracts that have no existing fallback provision or language that contemplates the discontinuation of LIBOR, and those investments could experience increased volatility or reduced liquidity as a result of the transition process. The transition may also result in a reduction in the value of certain instruments held by the Fund, a reduction in the effectiveness of related transactions, such as hedges, or a reduction in the value of any payments due to the Fund that are linked to LIBOR. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

LIQUIDITY RISK. The Fund has investments that it may not be able to dispose of or close out readily at a favorable time or price (or at all), or at a price approximating the Fund’s valuation of the investment. For example, certain investments may be subject to restrictions on resale, may trade over-the-counter or in limited volume, or may not have an active trading market. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. It may be difficult for the Fund to value illiquid securities accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. If the Fund needed to sell a large block of illiquid securities to meet shareholder redemption request or to raise cash, these sales could further reduce the securities’ prices and adversely affect performance of the Fund. Disposal of illiquid securities may entail registration expenses and other transaction costs that are higher than those for liquid securities.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative

impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

MORTGAGE-RELATED SECURITIES RISK. Mortgage-related securities are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. However, these investments make the Fund more susceptible to adverse economic, political or regulatory events that affect the value of real estate. Mortgage-related securities are also significantly affected by the rate of prepayments and modifications of the mortgage loans underlying those securities, as well as by other factors such as borrower defaults, delinquencies, realized or liquidation losses and other shortfalls. The incidence of borrower defaults or delinquencies may rise significantly during financial downturns and could adversely affect the value of mortgage-related securities held by the Fund. Events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events that result in broad and simultaneous financial hardships for individuals and businesses could have a significant negative impact on the value of mortgage-related securities. Mortgage-related securities are particularly sensitive to prepayment risk, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities. Nonetheless, the timing and amount of prepayments cannot be accurately predicted. The timing of changes in the rate of prepayments of the mortgage loans may significantly affect the Fund's actual yield to maturity on any mortgage-related securities, even if the average rate of principal payments is consistent with the Fund's expectation. Along with prepayment risk, mortgage-related securities are significantly affected by interest rate risk. In a low interest rate environment, mortgage loan prepayments would generally be expected to increase due to factors such as re-financings and loan modifications at lower interest rates. In contrast, if prevailing interest rates rise, prepayments of mortgage loans would generally be expected to decline and therefore extend the weighted average lives of mortgage-related securities held or acquired by the Fund. Fund investments in mortgage-backed securities issued by Ginnie Mae are backed by the full faith and credit of the U.S. government. Fund investments in mortgage-backed securities issued by Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

NON-AGENCY SECURITIES RISK. The Fund invests in non-agency securities. Investments in asset-backed or mortgage-backed securities offered by non-governmental issuers, such as commercial banks, savings and loans, private mortgage insurance companies, mortgage bankers and other secondary market issuers are subject to additional risks. There are no direct or indirect government or agency guarantees of payments in loan pools created by non-government issuers. Securities issued by private issuers are subject to the credit risks of the issuers. Timely payment of interest and principal of non-governmental issuers is supported by various forms of private insurance or guarantees, including individual loan, title, pool and hazard insurance purchased by the issuer. There can be no assurance that the private insurers can meet their obligations under the policies. Non-agency securities are also not subject to the same underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee. An unexpectedly high rate of defaults on the loan pool may adversely affect the value of a non-agency security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of loan pools that include subprime loans. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. Non-agency securities are typically traded “over the counter” rather than on a securities exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, the non-agency securities held by the Fund may be particularly difficult to value because of the complexities involved in assessing the value of the underlying loans.

NON-U.S. SECURITIES RISK. The Fund may invest in non-U.S. securities. An investment in securities of non-U.S. companies involves risks not associated with domestic issuers. Investment in non-U.S. securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by non-U.S. governments. Non-U.S. investments may also involve risks associated with the level of currency exchange rates, less complete financial information about the issuers, less market liquidity, more market volatility and political instability. Future political and economic developments, the possible imposition of withholding taxes on dividend income, the possible seizure or nationalization of non-U.S. holdings, the imposition of sanctions by foreign governments, the possible establishment of capital controls, exchange controls or freezes on the convertibility of currency or the adoption of other governmental restrictions might adversely affect an investment in non-U.S. securities. Additionally, non-U.S. issuers may be subject to less stringent regulation, and to different accounting, auditing and recordkeeping requirements. The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other regional developments particular to a given country or region.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

PREPAYMENT RISK. Prepayment risk is the risk that the issuer of a debt security will repay principal (in part or in whole) prior to the scheduled maturity date. Debt securities allowing prepayment may offer less potential for gains during a period of declining interest rates, as the Fund may be required to reinvest the proceeds of any prepayment at lower interest rates, reducing its income. If the Fund purchased the debt securities at a premium, prepayments on the securities could cause the Fund to lose a portion of its principal investment. These factors may cause the value of an investment in the Fund to change. The impact of prepayments on the price of a debt security may be difficult to predict and may increase the security’s volatility.

RESTRICTED SECURITIES RISK. The Fund invests in restricted securities. Restricted securities are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Restricted securities include private placement securities that have not been registered under the applicable securities laws, such as Rule 144A securities, and securities of U.S. and non-U.S. issuers that are issued pursuant to Regulation S. Private placements are generally subject to strict restrictions on resale. Restricted securities may be illiquid as they generally are not listed on an exchange and may have no active trading market. The Fund may be unable to sell a restricted security on short notice or may be able to sell them only at a price below current value. It may be more difficult to determine a market value for a restricted security. Also, the Fund may get limited information about the issuer of a restricted security, so it may be less able to predict a loss. In addition, if Fund management receives material non-public information about the issuer, the Fund may as a result be unable to sell the securities. Certain restricted securities may involve a high degree of business and financial risk and may result in substantial losses.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

in valuation of debt securities than for other types of securities. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund.

VOLATILITY RISK. Volatility is the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. The Fund may invest in securities or financial instruments that exhibit more volatility than the market as a whole. Such exposures could cause the Fund’s net asset value to experience significant increases or declines in value over short periods of time. Volatility can be caused by many factors, including changes in the economy or financial markets or for reasons specific to a particular issuer.

Non-Principal Risks

ASIA RISK. The Fund may invest in the securities of Asian issuers. Such investments subject the Fund to certain risks associated specifically with investments in securities of Asian issuers, including distinct legal, regulatory, political and economic risks. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Issuers in Asia may not be subject to the same accounting, auditing and financial reporting standards as U.S. companies and if their securities are not listed on a U.S. exchange, they may not be subject to the same corporate governance standards as U.S. issuers. In addition, satisfactory custodial services for investment securities may not be available in some Asia countries, which may result in the Fund incurring additional costs and delays in providing transportation and custody services for such securities outside such countries. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund.

BORROWING AND LEVERAGE RISK. If the Fund borrows money, it must pay interest and other fees, which may reduce the Fund’s returns. Any such borrowings are intended to be temporary. However, under certain market conditions, including periods of low demand or decreased liquidity, such borrowings might be outstanding for longer periods of time. As prescribed by the 1940 Act, the Fund will be required to maintain specified asset coverage of at least 300% with respect to any bank borrowing immediately following such borrowing and at all times thereafter. The Fund may be required to dispose of assets on unfavorable terms if market fluctuations or other factors reduce the Fund’s asset coverage to less than the prescribed amount.

CREDIT RATING AGENCY RISK. Credit ratings are determined by credit rating agencies such as Standard & Poor’s, Inc., Moody’s Investors Services, Inc. and Fitch Inc., and are only the opinions of such entities. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risk or the liquidity of securities. Any shortcomings or inefficiencies in credit rating agencies’ processes for determining credit ratings may adversely affect the credit ratings of securities held by the Fund and, as a result, may adversely affect those securities’ perceived or actual credit risk.

DEPENDENCE ON KEY PERSONNEL RISK. The Advisor is dependent upon the experience and expertise of the Fund’s portfolio managers in providing advisory services with respect to the Fund’s investments. If the Advisor were to lose the services of any of these portfolio managers, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for any of the portfolio managers in the event of their death, resignation, retirement or inability to act on behalf of the Advisor.

that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

EMERGING MARKETS RISK. The Fund may invest in securities issued by emerging market governments and companies incorporated in emerging market countries. Investments in securities issued by governments and companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed market countries. Moreover, emerging market countries often have less uniformity in accounting and reporting requirements, unsettled securities laws, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging market countries often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. and other developed market countries. In addition, significant delays may occur in registering the transfer of securities. Settlement or registration problems may make it more difficult for the Fund to value its portfolio securities and could cause the Fund to miss attractive investment opportunities. Investing in emerging market countries involves a higher risk of expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries. Enforcing legal rights may be made difficult, costly and slow in emerging markets as there may be additional problems enforcing claims against non-U.S. governments.

EUROPE RISK. The Fund may invest in the securities of European issuers. Therefore, in addition to the risks associated with investments in non-U.S. securities generally, the Fund is subject to certain risks associated specifically with investments in securities of European issuers. Political or economic disruptions in European countries, even in countries in which the Fund is not invested, may adversely affect security values and thus the Fund’s holdings. A significant number of countries in Europe are member states in the EU, and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU. After years of negotiations between the United Kingdom and the EU, a withdrawal agreement was reached whereby the United Kingdom formally left the EU. As the second largest economy among EU members, the implications of the United Kingdom’s withdrawal are difficult to gauge and cannot be fully known. Trade between the United Kingdom and the EU is highly integrated through supply chains and trade in services, as well as through multinational companies. The United Kingdom’s departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating political instability in the region).

FAILURE TO QUALIFY AS A REGULATED INVESTMENT COMPANY RISK. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. In such circumstances, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment. If the Fund fails to qualify as a regulated investment company, distributions to the Fund’s shareholders generally would be eligible for the dividends received deduction in the case of corporate shareholders. See “Federal Tax Matters.”

in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The ability to establish and close out positions in futures contracts is be subject to the development and maintenance of a liquid secondary market. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract at any particular time. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures contracts, for a number of reasons, may not correlate perfectly with movements in the securities or index underlying them. For example, participants in the futures markets are subject to margin deposit requirements less onerous than margin requirements in the securities markets in general. As a result, futures markets may attract more speculators than the securities markets. Increased participation by speculators in those markets may cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of general market trends by the Fund’s portfolio managers still may not result in a successful derivatives activity over a very short time period. The Commodity Futures Trading Commission and the various exchanges have established limits referred to as “speculative position limits” on the maximum net long or net short positions that any person and certain affiliated entities may hold or control in a particular futures contract. It is possible that, as a result of such limits, the Fund will be precluded from taking positions in certain futures contracts it might have otherwise taken to the disadvantage of shareholders.

HIGH YIELD SECURITIES RISK. The Fund’s investment in high yield securities, or “junk” bonds, may entail increased credit risks and the risk that the value of the Fund’s assets will decline, and may decline precipitously, with increases in interest rates. In recent years there have been wide fluctuations in interest rates and therefore in the value of debt securities generally. High yield securities are, under most circumstances, subject to greater market fluctuations and risk of loss of income and principal than are investments in lower-yielding, higher-rated debt securities. As interest rates rise, the value of high yield securities may decline precipitously. Increased rates may also indicate a slowdown in the economy which may adversely affect the credit of issuers of high yield securities resulting in a higher incidence of defaults among such issuers. A slowdown in the economy, or a development adversely affecting an issuer’s creditworthiness, may result in the issuer being unable to maintain earnings or sell assets at the rate and at the prices, respectively, that are required to produce sufficient cash flow to meet its interest and principal requirements. The Fund’s portfolio managers cannot predict future economic policies or their consequences or, therefore, the course or extent of any similar market fluctuations in the future. In addition, high yield securities are generally less liquid than investment grade securities.

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund may trade on non-U.S. exchanges that are closed when the Fund's primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market), resulting in premiums or discounts to the Fund's net asset value that may be greater than those experienced by other ETFs. However, because shares can be created and redeemed in Creation Units at the Fund’s net asset value, it is not expected that large discounts or premiums to the net asset value of the Fund will be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values).

INVESTMENT COMPANIES RISK. The Fund may invest in securities of other investment companies. As a shareholder in another investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the Fund will incur brokerage costs when purchasing and selling shares of exchange-traded investment companies.

ISSUER SPECIFIC CHANGES RISK. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

LATIN AMERICA RISK. The Fund may invest in Latin American issuers. The economies of Latin American countries have in the past experienced considerable difficulties, including high inflation rates, high interest rates, high unemployment, government overspending and political instability. International economic conditions, particularly those in the United States, Europe and Asia, as well as world prices for oil and other commodities may also influence the development of Latin American economies. Many Latin American countries are highly reliant on the exportation of commodities and their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities. In the past, certain Latin American economies have been influenced by changing supply and demand for a particular currency, monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries), and currency devaluations and revaluations. Other Latin American investment risks may include inadequate investor protection, less developed regulatory, accounting, auditing and financial standards, unfavorable changes in laws or regulations, natural disasters, corruption and

military activity. The governments of many Latin American countries may also exercise substantial influence over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Securities of companies in Latin America may also be subject to significant price volatility.

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed in the United States and abroad, which may have a negative impact on certain companies in which the Fund invests. In addition, litigation regarding any of the issuers of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Advisor determines to sell such a holding.

MUNICIPAL SECURITIES RISK. The values of municipal securities may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Other factors that could affect municipal securities include a change in the local, state, or national economy, demographic factors, ecological or environmental concerns, statutory limitations on the issuer’s ability to increase taxes, and other developments generally affecting the revenue of issuers (for example, legislation or court decisions reducing state aid to local governments or mandating additional services). This risk would be heightened to the extent that the Fund invests a substantial portion of its assets in bonds issued pursuant to similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), in industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds) that are particularly exposed to specific types of adverse economic, business or political events. Changes in a municipality’s financial health may also make it difficult for the municipality to make interest and principal payments when due. The values of municipal securities that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal securities to receive the cash flows generated by the revenue source. Under some circumstances, municipal securities might not pay interest unless the state legislature or municipality authorizes money for that purpose. Municipal securities may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund’s investments. In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund ’s investments. In addition, income from municipal securities held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other obligated party. Loss of tax-exempt status may cause interest received and distributed to shareholders by the Fund to be taxable and may result in a significant decline in the values of such municipal securities.

SOVEREIGN AND QUASI-SOVEREIGN DEBT SECURITIES RISK. Sovereign debt securities are issued or guaranteed by foreign governmental entities. Investments in such securities are subject to the risk that the relevant sovereign government or governmental entity may delay or refuse to pay interest or repay principal on its debt. Such delays or refusals may be due to cash flow problems, insufficient foreign currency reserves, political considerations, the size of its debt relative to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. A governmental entity may default on its obligations or may require renegotiation as to maturity or interest rate units of debt payments. Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. A restricting or default of sovereign debt security may cause additional impacts on financial markets such as downgrades to credit ratings, disruptions in trading markets, reduced liquidity and increase volatility. Additionally, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. The sovereign debt of many non-U.S. governments, including their sub-divisions and instrumentalities, is rated below investment-grade.

entities (such as Fannie Mae and Freddie Mac) are solely the obligation of the issuer and generally do not carry any guarantee from the U.S. government. No assurance can be given that the U.S. government will provide financial support to its government sponsored entities or any other agency if not obligated by law to do so.

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the "Investment Management Agreement"), First Trust manages the investment of the Fund’s assets. First Trust is paid an annual unitary management fee by the Fund equal to 0.45% of the Fund's average daily net assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

Pursuant to two separate contractual agreements, First Trust has agreed to waive management fees of 0.05% and 0.15% of average daily net assets until March 1, 2022. These waiver agreements will continue until March 1, 2022, subject to termination by action of the Trust’s Board of Trustees at any time upon 60 days’ written notice by the Trust on behalf of the Fund or by First Trust only after March 1, 2022. First Trust has committed to the fee waiver to respond to the current low interest rate environment and expects that the fee waiver will be appropriate until long term yields increase. First Trust anticipates that if the average yield over the prior 30-day period on the current one year U.S. Treasury Bond continues to exceed 1.50%, one or both fee waiver agreements may not be continued past March 1, 2022. Pursuant to an additional contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the portion of the management fees earned by First Trust from the Fund for assets invested in other investment companies advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Board or (ii) upon the termination of the Fund’s management agreement with First Trust. However, it is expected to remain in place for no less than one year from the date of this prospectus.

A discussion regarding the Board’s approval of the continuation of the Investment Management Agreement is available in the Fund’s Annual Report to shareholders for the fiscal year ended October 31, 2020.

How to Buy and Sell Shares

Most investors buy and sell shares of the Fund in secondary market transactions through brokers. Shares of the Fund are listed for trading on the secondary market on one or more national securities exchanges. Shares can be bought and sold throughout the trading day like other publicly traded shares. There is no minimum investment when buying shares on the Exchange. Although shares are generally purchased and sold in “round lots” of 100 shares, brokerage firms typically permit investors to purchase or sell shares in smaller “odd lots,” at no per-share price differential. When buying or selling shares through a broker, investors should expect to pay brokerage commissions, investors may receive less than the net asset value of the shares because shares are bought and sold at market prices rather than at net asset value, and investors may pay some or all of the bid-ask spread for each transaction (purchase or sale) of Fund shares. Share prices are reported in dollars and cents per share.

Under normal circumstances, the Fund will pay out redemption proceeds to a redeeming authorized participant within two days after the authorized participant’s redemption request is received, in accordance with the process set forth in the Fund’s SAI and in the agreement between the authorized participant and the Fund’s distributor. However, the Fund reserves the right, including under stressed market conditions, to take up to seven days after the receipt of a redemption request to pay an authorized participant, all as permitted by the 1940 Act. If the Fund has foreign investments in a country where a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming authorized participants prevents the Fund from delivering such foreign investments to an authorized participant in response to a redemption request, the Fund may take up to 15 days after the receipt of the redemption request to deliver such investments to the authorized participant.

the Fund, has received an exemptive order from the Securities and Exchange Commission that permits certain registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that any such investment companies enter into an agreement with the Fund regarding the terms of any investment.

Book Entry

Shares are held in book-entry form, which means that no share certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of share certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book-entry or “street name” form.

Share Trading Prices

The trading price of shares of the Fund on the secondary market is based on market price and may differ from the Fund’s daily net asset value and can be affected by market forces of supply and demand, economic conditions and other factors.

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objective. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker.

Federal Tax Matters

a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, counsel to the Fund was not asked to review, and has not reached a conclusion with respect to, the federal income tax treatment of the assets to be included in the Fund. The following disclosure may not be sufficient for you to use for the purpose of avoiding penalties under federal tax law.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

After the end of each year, you will receive a tax statement that separates the distributions of the Fund into three categories, exempt-interest dividends, ordinary income distributions and capital gain dividends. Dividends that qualify as “exempt-interest dividends” generally are excluded from your gross income for federal income tax purposes. Some or all of the exempt-interest dividends, however, may be taken into account in determining your alternative minimum tax and may have other tax consequences (e.g., they may affect the amount of your social security benefits that are taxed). Ordinary income distributions are generally taxed at your ordinary tax rate. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Income from the Fund may also be subject to a 3.8% “Medicare tax.” This tax generally applies to your net investment income if your adjusted gross income exceeds certain threshold amounts, which are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single individuals. Interest that is excluded from gross income and exempt-interest dividends from the Fund are generally not included in your net investment income for purposes of this tax.

Dividends Received Deduction

Capital Gains and Losses

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your share to determine your holding period. If you hold a share for six months or less, any loss incurred by you related to the disposition of such share will be disallowed to the extent of the exempt-interest dividends you received, except in the case of a regular dividend paid by the Fund if the Fund declares exempt-interest dividends on a daily basis in an amount equal to at least 90 percent of its net tax-exempt interest and distributes

such dividends on a monthly or more frequent basis. To the extent, if any, it is not disallowed, it will be recharacterized as long-term capital loss to the extent of any capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. Further, if you hold your shares for six months or less, any loss incurred by you related to the disposition of such a share will be disallowed to the extent of the exempt-interest dividends you received, except as otherwise described in the prior paragraph. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the Cash Redemption Amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you. If the Fund pays exempt-interest dividends, which are treated as exempt interest for federal income tax purposes, you will not be able to deduct some of your interest expense for debt that you incur or continue to purchase or carry your shares.

Non-U.S. Tax Credit

If the Fund invests in non-U.S. securities, the tax statement that you receive may include an item showing non-U.S. taxes the Fund paid to other countries. In this case, dividends taxed to you will include your share of the taxes the Fund paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes.

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and, other than exempt-interest dividends, will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

Investments in Certain Non-U.S. Corporations

If the Fund holds an equity interest in any “passive foreign investment companies” (“PFICs”), which are generally certain non‑U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by PFICs are not treated as qualified dividend income.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

The Board has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse FTP for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are APs for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.

The Fund does not currently pay 12b-1 fees, and pursuant to a contractual arrangement, the Fund will not pay 12b-1 fees any time before March 31, 2022. However, in the event 12b-1 fees are charged in the future, because these fees are paid out of the Fund's assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.

Net Asset Value

The Fund's net asset value is determined as of the close of trading (normally 4:00 p.m., Eastern Time) on each day the New York Stock Exchange is open for business. Net asset value is calculated for the Fund by taking the market price of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing such amount by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Board or its delegate.

The Fund’s investments are valued daily in accordance with valuation procedures adopted by the Board, and in accordance with provisions of the 1940 Act. Certain securities in which the Fund may invest are not listed on any securities exchange or board of trade. Such securities are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over the counter secondary market, although typically no formal market makers exist. Certain securities, particularly debt securities, have few or no trades, or trade infrequently, and information regarding a specific security may not be widely available or may be incomplete. Accordingly, determinations of the fair value of debt securities may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. Typically, debt securities are valued using information provided by a third-party pricing service. The third-party pricing service primarily uses broker quotes to value the securities.

Nasdaq or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

Mortgage-related debt securities and other mortgage-related instruments ("Mortgage-Related Investments") will generally be valued by using a third-party pricing service. If a pricing service does not cover a particular Mortgage-Related Investment, or discontinues covering a Mortgage-Related Investment, the security will be priced using a broker quote. To derive values, pricing services and broker-dealers may use matrix pricing and valuation models, as well as recent market transactions for the same or similar assets. Occasionally, the Advisor’s pricing committee (the "Pricing Committee") may determine that a pricing service price does not represent an accurate value of a Mortgage-Related Investment, based on the broker quote it receives, a recent trade in the security by the Fund, information from a portfolio manager, or other market information. In the event that the Pricing Committee determines that the pricing service price is unreliable or inaccurate based on such other information, the broker quote may be used. Additionally, if the Pricing Committee determines that the price of a Mortgage-Related Investment obtained from a pricing service and the available broker quote is unreliable or inaccurate due to market conditions or other reasons, or if a pricing service price or broker quote is unavailable, the security will be valued using fair value pricing, as described below.

Loans in which the Fund invests are not listed on any securities exchange or board of trade. Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some loans have few or no trades, or trade infrequently, and information regarding a specific loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of loans than for other types of securities. Typically, loans are fair valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the loans.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board or its delegate, the Advisor’s Pricing Committee, at fair value. The use of fair value pricing by the Fund is governed by valuation procedures adopted by the Board and in accordance with the provisions of the 1940 Act. These securities generally include, but are not limited to, certain restricted securities (securities which may not be publicly sold without registration under the Securities Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund's net asset value or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from the current market valuations. See the Fund's SAI for details.

Because foreign securities exchanges may be open on different days than the days during which an investor may purchase or sell shares of the Fund, the value of the Fund's securities may change on days when investors are not able to purchase or sell shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Fund Service Providers

Premium/Discount Information

Information showing the number of days the market price of the Fund's shares was greater (at a premium) and less (at a discount) than the Fund's net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter), is available at https://www.ftportfolios.com/Retail/etf/home.aspx.

Total Return Information

The table below compares the total return of the Fund to a market index. The information presented for the Fund is for the period indicated.

“Average annual total returns” represent the average annual change in the value of an investment over the period indicated. “Cumulative total returns” represent the total change in value of an investment over the period indicated. The return information shown under “Annual Total Return” in the Fund’s summary prospectus represents the average annual total returns of the Fund as of the calendar year end, while the information presented below is as of the Fund’s fiscal year end. The net asset value per share of the Fund is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The net asset value return is based on the net asset value per share of the Fund and the market return is based on the market price per share of the Fund. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund's NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund's NAV was calculated. Since the shares of the Fund typically do not trade in the secondary market until several days after the Fund's inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the net asset value of the Fund is used as a proxy for the secondary market trading price to calculate market returns. Market and net asset value returns assume that all distributions have been reinvested in the Fund at Market Price and net asset value, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns reflect the reinvestment of dividends on securities in the index. The returns shown in the table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of shares of the Fund. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future results.

Principal Investment Strategies

Under normal market conditions, the Fund will seek to achieve its investment objectives by investing at least 60% of its net assets (including investment borrowings) (the “60% Requirement”) in mortgage-related debt securities and other mortgage-related instruments (collectively, “Mortgage-Related Investments”). The Fund normally expects to invest in Mortgage-Related Investments tied to residential and commercial mortgages. Mortgage-Related Investments consist of: (1) residential mortgage-backed securities (RMBS); (2) commercial mortgage-backed securities (CMBS); (3) stripped mortgage-backed securities (SMBS), which are mortgage-backed securities where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest; and (4) collateralized mortgage obligations (CMOs) and real estate mortgage investment conduits (REMICs) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets. Mortgage-Related Investments typically represent an interest in a pool of mortgage loans made by banks and other financial institutions. The individual mortgage loans are packaged or “pooled” together for sale to investors. As the underlying mortgage loans are paid off, investors

receive principal and interest payments. Mortgage-Related Investments may be fixed-rate or adjustable-rate Mortgage-Related Investments (ARMS).

The mortgage-backed securities in which the Fund invests may be, but are not required to be, issued or guaranteed by the U.S. government or its agencies or instrumentalities, such as the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association (“FNMA”), and the Federal Home Loan Mortgage Corporation (“FHLMC”) (the U.S. government, its agencies and instrumentalities, and U.S. government-sponsored entities are referred to collectively as “Government Entities”). The Fund may invest in callable agency securities, which give the issuer the right to redeem the security prior to maturity. The Fund may invest up to 40% of its net assets (including investment borrowings), in the aggregate, in (i) cash, cash equivalents and short-term investments and (ii) non-mortgage direct obligations of the U.S. government and other non-mortgage securities issued and/or guaranteed by Government Entities (the “40% Limit”). The Fund will limit its investments in Mortgage-Related Investments that are neither issued nor guaranteed by Government Entities to 20% of its net assets (including investment borrowings). The Fund may also invest up to 5% of its net assets (including investment borrowings) in asset-backed securities (“ABS”) (other than Mortgage-Related Investments) that are not issued and/or guaranteed by Government Entities. However, the Fund’s investments in (a) Mortgage-Related Investments that are not issued and/or guaranteed by Government Entities and (b) ABS may not, in the aggregate, exceed 20% of the Fund’s net assets (including investment borrowings).

The Fund targets an estimated effective duration of three (3) years or less. Duration is a mathematical calculation of the average life of a debt security (or portfolio of debt securities) that serves as a measure of its price risk. In general, each year of duration represents an expected 1% change in the value of a security for every 1% immediate change in interest rates. For example, if a portfolio of mortgage loans has an average duration of three years, its value can be expected to fall about 3% if interest rates rise by 1%. Conversely, the portfolio’s value can be expected to rise about 3% if interest rates fall by 1%. As a result, prices of instruments with shorter durations tend to be less sensitive to interest rate changes than instruments with longer durations. As the value of a security changes over time, so will its duration. The Fund’s investment advisor will calculate the duration of the portfolio by modeling the cash flows of all the individual holdings, including the impact of prepayment variability and coupon adjustments where applicable, to determine the duration of each holding and then aggregating based on the size of the position. In performing this duration calculation, the Fund’s advisor will utilize third-party models.

The Fund may invest, without limitation, in mortgage dollar rolls. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Fund’s investment advisor. In a mortgage dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. The Fund may also invest in to-be-announced transactions (“TBA Transactions”). A TBA Transaction is a method of trading mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price. Further, the Fund may enter into short sales as part of its overall portfolio management strategies or to offset a potential decline in the value of a security; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets (including investment borrowings). To the extent required under applicable federal securities laws, rules, and interpretations thereof, the Fund will “set aside” liquid assets or engage in other measures to “cover” open positions and short positions held in connection with the foregoing types of transactions. To the extent that cash, cash equivalents and short-term investments are set aside, earmarked or otherwise held as collateral for settling mortgage dollar rolls, TBA Transactions, other forward-settling Mortgage-Related Investments transactions and/or exchange-listed futures contracts, the Fund may include such cash, cash equivalents and short-term investments towards the 60% Requirement rather than the 40% Limit.

Although the Fund intends to invest primarily in investment grade securities, the Fund may invest up to 20% of its net assets (including investment borrowings) in securities of any credit quality, including securities that are below investment grade, which are also known as high yield securities, or commonly referred to as “junk” bonds, or unrated securities that have not been judged by the advisor to be of comparable quality to rated investment grade securities. In the case of a split rating between one or more of the nationally recognized statistical rating organizations, the Fund will consider the highest rating.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objectives will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

ASSET-BACKED SECURITIES RISK. Asset-backed securities are debt securities typically created by buying and pooling loans or other receivables other than mortgage loans and creating securities backed by those similar type assets. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. These securities are generally not backed by the full faith and credit of the U.S. government and are subject to the risk of default on the underlying asset or loan, particularly during periods of economic downturn. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

FUTURES CONTRACTS RISK. Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset by one party to another at a certain price and date, or cash settlement of the terms of the contract. The risk of a position in a futures contract may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. In the event no secondary market exists for a particular contract, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures contracts may not correlate perfectly with movements in the securities or index underlying them.

HIGH YIELD SECURITIES RISK. High yield securities, or “junk” bonds, are subject to greater market fluctuations, are less liquid and provide a greater risk of loss than investment grade securities, and therefore, are considered to be highly speculative. In general, high yield securities may have a greater risk of default than other types of securities and could cause income and principal losses for the Fund.

INTEREST AND PRINCIPAL ONLY SECURITIES RISK . The Fund may invest in stripped mortgage-backed securities where mortgage payments are divided up between one class that receives all of the interest from the mortgage assets (interest-only securities), while the other class will receive all of the principal (the principal-only securities). The yield to maturity on an interest-only security is extremely sensitive to the rate of principal payments (including prepayments) on the underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on the Fund’s yield to maturity from these securities. If the assets underlying the interest-only securities experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully, or at all, its initial investment in these securities. Conversely, principal-only securities tend to decline in value if prepayments are slower than anticipated.

their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund's ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options.

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.While securities issued or guaranteed by U.S. federal government agencies (such as Ginnie Mae) are backed by the full faith and credit of the U.S. Department of the Treasury, securities issued by government sponsored entities (such as Fannie Mae and Freddie Mac) are solely the obligation of the issuer and generally do not carry any guarantee from the U.S. government.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Returns before taxes do not reflect the effects of any income or capital gains taxes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of shares assume you sold your shares at period end, and, therefore, are also adjusted for any capital gains or losses incurred. Returns for the market indices do not include expenses, which are deducted from Fund returns, or taxes.

Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares on a continuous basis, at net asset value, only in large blocks of shares called “Creation Units.” Individual shares of the Fund may only be purchased and sold on the secondary market through a broker-dealer. Since shares of the Fund trade on securities exchanges in the secondary market at their market price rather than their net asset value, the Fund’s shares may trade at a price greater than (premium) or less than (discount) the Fund’s net asset value. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Recent information, including the Fund’s net asset value, market price, premiums and discounts, and bid-ask spreads, is available online at https://www.ftportfolios.com/Retail/etf/home.aspx.

Tax Information

The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains. Distributions on shares held in a tax-deferred account, while not immediately taxable, will be subject to tax when the shares are no longer held in a tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), First Trust and First Trust Portfolios L.P., the Fund’s distributor, may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional Information on the Fund's Investment Objectives and Strategies

The Fund is a series of First Trust Exchange-Traded Fund IV and is regulated as an “investment company” under the 1940 Act. The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objectives are fundamental and may not be changed without approval by the holders of a majority of the outstanding voting securities of the Fund. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. If there is a material change to the Fund’s principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objectives.

Additional Information on the Fund’s Strategy

The Fund will invest at least 60% of its net assets (including investment borrowings) in mortgage-related debt securities and other mortgage-related instruments. The Fund may invest up to 40% of its net assets (including investment borrowings), in the aggregate, in (i) cash, cash equivalents and short-term investments and (ii) non-mortgage direct obligations of the U.S. government and other non-mortgage securities issued and/or guaranteed by Government Entities. To the extent that cash, cash equivalents and short-term investments are set aside, earmarked or otherwise held as collateral for settling mortgage dollar rolls, TBA Transactions, other forward-settling Mortgage-Related Investments transactions and/or exchange-listed futures contracts, the Fund may include such cash, cash equivalents and short-term investments towards the 60% Requirement rather than the 40% Limit.

The Fund targets an estimated effective duration of three years or less. In comparison to maturity (i.e., the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the expected price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments and other factors. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments, call features and coupon adjustments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with lower durations tend to be less sensitive to interest rate changes than securities with higher durations. In general, a portfolio of securities with a lower duration can be expected to be less sensitive to interest rate changes than a portfolio with a higher duration.

Fund Investments

Principal Investments

Mortgage-Related Investments

The Fund invests in Mortgage-Related Investments. Mortgage-backed securities represent direct or indirect participations in, or are secured by and payable from, mortgage loans secured by real property and can include single- and multi-class pass-through securities and collateralized mortgage obligations. Mortgage-backed securities are based on different types of mortgages, including those on commercial real estate or residential properties. These securities often have stated maturities of up to thirty years when they are issued, depending upon the length of the mortgages underlying the securities.

The Fund generally expects that the Mortgage-Related Investments in which it invests will primarily consist of investment grade securities at the time of purchase. The Mortgage-Related Investments in which the Fund invests include mortgage-backed securities (such as RMBS and CMBS). Certain mortgage-backed securities (including RMBS and CMBS), where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest, are referred to as stripped mortgage-backed securities (SMBS). Further, mortgage-backed securities can also be categorized as collateralized mortgage obligations (CMOs) or real estate mortgage investment conduits (REMICs) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets.

Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. The FNMA and FHLMC pass-through mortgage certificates are backed by the credit of the respective instrumentality and are not guaranteed by the U.S. government. Other securities issued by government agencies or instrumentalities, including government-sponsored entities, may only be backed by the creditworthiness of the issuing institution, not the U.S. government, or the issuers may have the right to borrow from the U.S. Treasury to meet their obligations. Many mortgage-backed securities are pass-through securities, which means they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately. Adjustable-rate mortgage-backed securities include ARMS and other mortgage-backed securities with interest rates that adjust periodically to reflect prevailing market rates.

Additionally, the Fund may invest in mortgage dollar rolls. In a mortgage dollar roll, the Fund will sell (or buy) mortgage- backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. During the period between a sale and repurchase, the Fund will forgo principal and interest paid on the mortgage-backed securities. The Fund will earn or lose money on a mortgage dollar roll from any difference between the sale price and the future purchase price. In a sale and repurchase, the Fund will also earn money on the interest earned on the cash proceeds of the initial sale. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Advisor.

The Fund may also invest in TBA Transactions. A TBA Transaction is a method of trading mortgage-backed securities. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price. The actual pools delivered generally are determined two days prior to the settlement date.

High Yield Debt

The Fund invests primarily in Mortgage-Related Investments, a portion of which may be rated below investment grade, or unrated securities deemed by the Fund’s portfolio managers to be of comparable quality. Securities rated below investment grade are commonly referred to as high yield or “junk” debt. For purposes of determining whether a security is below investment grade, the highest available rating will be considered.

U.S. Government Securities

The Fund may also invest in callable agency securities, which give the issuer (the U.S. government agency) the right to redeem the security prior to maturity. The Fund may also invest in U.S. government inflation-indexed securities.

At times, the Fund may allocate its investments into direct obligations of the U.S. government (such as Treasury bonds, bills and notes) and in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, including government-sponsored entities.

Cash Equivalents and Short-Term Investments

The Fund may invest in securities with maturities of less than one year or cash equivalents, or it may hold cash, in order to collateralize its investments or for temporary defensive purposes. Such securities include securities issued by issuers having a long-term debt rating of at least “A” by Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc. (currently known as S&P Global Ratings) (“S&P Ratings”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch Ratings (“Fitch”) and having a maturity of one year or less and include, without limitation, the following: (1) fixed rate and floating rate U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities; (2) certificates of deposit issued against funds deposited in a bank or savings and loan association; (3) bankers’ acceptances; (4) repurchase agreements; (5) bank time deposits; and (6) commercial paper. The percentage of the Fund invested in these types of holdings varies and depends on several factors, including market conditions. For temporary defensive purposes, during the initial invest-up period and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities or it may hold cash. During such periods, the Fund may not be able to achieve its investment

objective. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the Fund’s SAI.

Non-Principal Investments

Derivative Instruments

The Fund may hold listed derivatives, including futures, options and swaps on commodities, currencies and financial instruments, or a basket or index of any of the foregoing. Additionally, the Fund may hold derivatives traded over-the-counter ("OTC”), including forwards, swaps, options and swaps on commodities, currencies and financial instruments, or a basket or index of any of the foregoing. However, on both an initial and continuing basis, no more than 20% of the assets in the Fund's portfolio may be invested in OTC derivatives. The use of these derivative transactions may allow the Fund to obtain net long or short exposures to selected interest rates or durations. The Fund may also utilize derivatives to enhance return, to hedge some of the risks of its investments in securities, as a substitute for a position in the underlying asset, to reduce transaction costs, to maintain full market exposure (which means to adjust the characteristics of its investments to more closely approximate those of the markets in which it invests), to manage cash flows, to limit exposure to losses due to changes to non-U.S. currency exchange rates or to preserve capital.

Illiquid Securities

The Fund may invest up to 15% of its net assets in securities and other instruments that are, at the time of investment, illiquid (determined using the Securities and Exchange Commission’s standard applicable to investment companies, i.e., securities that cannot be disposed of by the Fund within seven days in the ordinary course of business at approximately the amount at which the Fund has valued the securities). For this purpose, illiquid securities may include, but are not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), that are deemed to be illiquid, and certain repurchase agreements.

Investment Companies and Other Pooled Investment Vehicles

The Fund may invest in securities of other investment companies, including exchange-traded funds (“ETFs”) that invest primarily in Mortgage-Related Investments. As a shareholder in an investment company or pooled investment vehicle, the Fund bears its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other pooled investment vehicles. In addition, the Fund incurs brokerage costs when purchasing and selling shares of ETFs. Securities of certain investment companies may be leveraged, in which case the value and/or yield of such securities tends to be more volatile than securities of unleveraged investment companies.

The Fund's ability to invest in other investment companies is limited by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) and 12(d)(1)(G) of the 1940 Act.

Disclosure of Portfolio Holdings

The Fund’s portfolio holdings are available on the Fund's website at www.ftportfolios.com. A description of the policies and procedures with respect to the disclosure of the Fund's portfolio securities is included in the Fund's SAI, which is also available on the Fund's website.

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objectives. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

ASSET-BACKED SECURITIES RISK. The Funds may invest in asset-backed securities. Asset-backed securities are debt securities typically created by buying and pooling loans or other receivables other than mortgage loans and creating securities backed

by those similar type assets. They are typically issued by trusts and special purpose co-purchasers that pass income from the underlying pool to investors. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. Certain asset-backed securities do not have the benefit of the same security interest in the related collateral as do mortgage-backed securities, nor are they provided government guarantees of repayment. Credit card receivables are generally unsecured, and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. In addition, some issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CASH TRANSACTIONS RISK. The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A Fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

COUNTERPARTY RISK. If the Fund enters into an investment or transaction that depends on the performance of another party, the Fund becomes subject to the credit risk of that counterparty. The Fund's ability to profit from these types of investments and transactions depends on the willingness and ability of the Fund’s counterparty to perform its obligations. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving a counterparty (including recovery of any collateral posted by it) and may obtain only a limited recovery or may obtain no recovery in such circumstances. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty. Under applicable law or contractual provisions, including if the Fund enters into an investment or transaction with a financial institution and such financial institution (or an affiliate of the financial institution) experiences financial difficulties, then the Fund may in certain situations be prevented or delayed from exercising its rights to terminate the investment or transaction, or to realize on any collateral and may result in the suspension of payment and delivery obligations of the parties under such investment or transactions or in another institution being substituted for that financial institution without the consent of the Fund. Further, the Fund may be subject to “bail-in” risk under applicable

law whereby, if required by the financial institution's authority, the financial institution's liabilities could be written down, eliminated or converted into equity or an alternative instrument of ownership. A bail-in of a financial institution may result in a reduction in value of some or all of securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, the Fund may also be similarly impacted.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause a Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

FLOATING RATE DEBT INSTRUMENTS RISK. Investments in floating rate debt instruments are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. The Fund may invest in floating rate loans considered to be high yield, or “junk,” instruments and considered speculative because of the credit risk of their issuers. Such issuers are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund. An economic downturn would also generally lead to a higher non-payment rate, and a floating rate debt instrument may lose significant market value before a default occurs. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods which may cause the Fund to be unable to realize the full value of its investment. Lastly, floating rate loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

FUTURES CONTRACTS RISK. The Fund may enter into futures contracts. Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset by one party to another at a certain price and date, or cash settlement of the terms of the contract. The risk of a position in a futures contract may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The ability to establish and close out positions in futures contracts is be subject to the development and maintenance of a liquid secondary market. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract at any particular time. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures contracts, for a number of reasons, may not correlate perfectly with movements in the securities or index underlying them. For example, participants in the futures markets are subject to margin deposit requirements less onerous than margin requirements in the securities markets in general. As a result, futures markets may attract more speculators than the securities markets. Increased participation by speculators in those markets may cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of

general market trends by the Fund’s portfolio managers still may not result in a successful derivatives activity over a very short time period. The Commodity Futures Trading Commission and the various exchanges have established limits referred to as “speculative position limits” on the maximum net long or net short positions that any person and certain affiliated entities may hold or control in a particular futures contract. It is possible that, as a result of such limits, the Fund will be precluded from taking positions in certain futures contracts it might have otherwise taken to the disadvantage of shareholders.

since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. An increase in interest rates could also cause principal payments on a debt security to be repaid at a slower rate than expected. This risk is particularly prevalent for a callable debt security where an increase in interest rates could cause the issuer of that security to not redeem the security as anticipated on the call date, effectively lengthening the security’s expected maturity, in turn making that security more vulnerable to interest rate risk and reducing its market value. When interest rates fall, the Fund may be required to reinvest the proceeds from the sale, redemption or early prepayment of a debt security at a lower interest rate.

LIQUIDITY RISK. The Fund may have investments that it may not be able to dispose of or close out readily at a favorable time or price (or at all), or at a price approximating the Fund’s valuation of the investment. For example, certain investments may be subject to restrictions on resale, may trade over-the-counter or in limited volume, or may not have an active trading market. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. It may be difficult for the Fund to value illiquid securities accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. If the Fund needed to sell a large block of illiquid securities to meet shareholder redemption request or to raise cash, these sales could further reduce the securities’ prices and adversely affect performance of the Fund. Disposal of illiquid securities may entail registration expenses and other transaction costs that are higher than those for liquid securities.

disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

strike price. As the buyer of a put or call option, the buyer risks losing the entire premium invested in the option if the buyer does not exercise the option. The effective use of options also depends on the Fund's ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Options may also involve the use of leverage, which could result in greater price volatility than other markets.

PORTFOLIO TURNOVER RISK. The Fund has an investment strategy that may frequently involve buying and selling portfolio securities. High portfolio turnover may result in the Fund paying higher levels of transaction costs, including brokerage commissions, dealer mark-ups and other costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

REPURCHASE AGREEMENT RISK. The Fund may enter into repurchase agreements. A repurchase agreement is an agreement to purchase a security from a party at one price and a simultaneous agreement to sell it back to the original party at an agreed-upon price, typically representing the purchase price plus interest. Repurchase agreements may be viewed as loans made by the Fund which are collateralized by the securities subject to repurchase. The Fund's investment return on such transactions will depend on the counterparty's willingness and ability to perform its obligations under a repurchase agreement. If the Fund's counterparty should default on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may have to borrow cash, subject to certain legal limits, or realize a loss.

SHORT SALES RISK. The Fund may engage in short sales. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. The risk of loss on a shorted position arises from the increase in value of the security sold short and is potentially unlimited unlike the risk of loss on a long position, which is limited to the amount paid for the investment plus transaction costs. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, in times of unusual or adverse economic, market or political conditions, the Fund may not be able to fully or partially implement its short selling strategy. In addition, as a series of an investment company registered under the 1940 Act, the Fund must segregate liquid assets, or engage in other measures to “cover” open positions with respect to short sales. The Fund may nonetheless incur significant losses on short sales even if they are covered.

than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

TBA TRANSACTIONS RISK. The Fund may purchase securities via TBA Transactions. In such a transaction, the purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchasing securities in a TBA Transaction may give rise to investment leverage and may increase the Fund’s volatility. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. The Financial Industry Regulatory Authority recently imposed mandatory margin requirements for certain types of TBA Transactions. Such transactions historically have not been required to be collateralized, and, if those rules are implemented, mandatory collateralization could increase the cost of such transactions and impose added operational complexity.

U.S. GOVERNMENT SECURITIES RISK. The Fund may invest in U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.While securities issued or guaranteed by U.S. federal government agencies (such as Ginnie Mae) are backed by the full faith and credit of the U.S. Department of the Treasury, securities issued by government sponsored entities (such as Fannie Mae and Freddie Mac) are solely the obligation of the issuer and generally do not carry any guarantee from the U.S. government. No assurance can be given that the U.S. government will provide financial support to its government sponsored entities or any other agency if not obligated by law to do so.

Non-Principal Risks

any of these portfolio managers, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for any of the portfolio managers in the event of their death, resignation, retirement or inability to act on behalf of the Advisor.

RESTRICTED SECURITIES RISK. Restricted securities are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Restricted securities include private placement securities that have not been registered under the applicable securities laws, such as Rule 144A securities, and securities of U.S. and non-U.S. issuers that are issued pursuant to Regulation S. Private placements are generally subject to strict restrictions on resale. Restricted securities may be illiquid as they generally are not listed on an exchange and may have no active trading market. The Fund may be unable to sell a restricted security on short notice or may be able to sell them only at a price below current value. It may be more difficult to determine a market value for a restricted security. Also, the Fund may get limited information about the issuer of a restricted security, so it may be less able to predict a loss. In addition, if Fund management receives material non-public information about the issuer, the Fund may as a result be unable to sell the securities. Certain restricted securities may involve a high degree of business and financial risk and may result in substantial losses.

Fund Organization

The Fund is a series of the Trust, an investment company registered under the 1940 Act. The Fund is treated as a separate fund with its own investment objectives and policies. The Trust is organized as a Massachusetts business trust. The Board is responsible for the overall management and direction of the Trust. The Board elects the Trust’s officers and approves all significant agreements, including those with the Advisor, custodian and fund administrative and accounting agent.

Management of the Fund

First Trust serves as advisor or sub-advisor for 8 mutual fund portfolios, 10 exchange-traded funds consisting of 172 series and 16 closed-end funds. It is also the portfolio supervisor of certain unit investment trusts sponsored by First Trust Portfolios L.P. (“FTP”), an affiliate of First Trust, 120 East Liberty Drive, Wheaton, Illinois 60187. FTP specializes in the underwriting, trading and distribution of unit investment trusts and other securities. FTP is the principal underwriter of the shares of the Fund.

James Snyder and Jeremiah Charles are the Fund’s portfolio managers and are jointly and primarily responsible for the day-to-day management of the Fund’s investment portfolio.

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the "Investment Management Agreement”), First Trust manages the Fund's assets. First Trust is paid an annual unitary management fee by the Fund equal to 0.65% of the Fund’s average daily net assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

How to Buy and Sell Shares

authorized participants prevents the Fund from delivering such foreign investments to an authorized participant in response to a redemption request, the Fund may take up to 15 days after the receipt of the redemption request to deliver such investments to the authorized participant.

For purposes of the 1940 Act, the Fund is treated as a registered investment company, and, absent an available exemption or exemptive relief, the acquisition of shares by other registered investment companies and companies relying on Sections 3(c)(1) or 3(c)(7) of the 1940 Act is subject to the restrictions of Section 12(d)(1) of the 1940 Act. The Trust, on behalf of the Fund, has received an exemptive order from the Securities and Exchange Commission that permits certain registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that any such investment companies enter into an agreement with the Fund regarding the terms of any investment.

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories: ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate, however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

A corporation that owns shares generally will not be entitled to the dividends received deduction with respect to many dividends received from the Fund because the dividends received deduction is generally not available for distributions from regulated investment companies. However, certain ordinary income dividends on shares that are attributable to qualifying dividends received by the Fund from certain corporations may be reported by the Fund as being eligible for the dividends received deduction.

Capital Gains and Losses and Certain Ordinary Income Dividends

a capital gain dividend from the Fund and sell your shares at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Ordinary income dividends received by an individual shareholder from a regulated investment company such as the Fund are generally taxed at the same rates that apply to net capital gain (as discussed above), provided certain holding period requirements are satisfied and provided the dividends are attributable to qualifying dividends received by the Fund itself. The Fund will provide notice to its shareholders of the amount of any distribution which may be taken into account as a dividend which is eligible for the capital gains tax rates.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Because the Fund invests in non-U.S. securities, the tax statement that you receive may include an item showing non-U.S. taxes the Fund paid to other countries. In this case, dividends taxed to you will include your share of the taxes the Fund paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes.

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

entities that do not provide certain certifications and information about the entity’s U.S. owners. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

Investments in Certain Non-U.S. Corporations

If the Fund holds an equity interest in any “passive foreign investment companies” (“PFICs”), which are generally certain non-U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by PFICs are not treated as qualified dividend income.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

(“AIM”) are valued at the last sale price on the business day as of which such value is being determined. Securities listed on Nasdaq or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by Energy Income Partners, LLC, the Fund’s investment sub-advisor ("Energy Income Partners" or the "Sub-Advisor"), to be engaged in the energy infrastructure sector. These companies principally include U.S. and Canadian natural gas and electric utilities, corporations operating energy infrastructure assets such as pipelines or renewable energy production, utilities, publicly-traded master limited partnerships or limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, and other companies that derive the majority of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, “energy infrastructure companies”). The Fund will invest principally in energy infrastructure companies. In addition, under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies headquartered or incorporated in the United States and Canada. As of January 31, 2021, the Fund had significant investments in energy infrastructure and utility companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

The Fund may invest in equity securities of MLPs without limit; however, in order to comply with applicable tax diversification rules, the Fund may directly invest up to 25% of its total assets in equity securities of certain MLPs treated as publicly-traded partnerships.

The Fund’s investment strategy emphasizes current distributions and dividends paid to shareholders. The Sub-Advisor believes that a professionally managed portfolio of higher dividend paying MLPs, MLP affiliates, utilities, pipeline and power companies, and other energy infrastructure companies in non-cyclical segments that offer an attractive balance of income and growth. The Sub-Advisor believes that the non-cyclical assets that best support a high-payout ratio are those with steady, fee-for-service businesses with relatively low sustaining capital obligations. In the energy infrastructure sector, such fee-for-service assets are comprised of but not limited to interstate pipelines, intrastate pipelines with long-term contracts, power generation assets, storage and terminal facilities with long-term contracts and regulated power transmission and distribution assets. By contrast, the Sub-Advisor will seek to limit the cyclical energy exposure of the portfolio. The Sub-Advisor believes that portfolio investments in oil and gas exploration, development and production are less well suited for the Fund because the cash flows from these investments are cyclical in nature, being driven by commodity prices, and because oil and gas assets are wasting assets. The Sub-Advisor believes the use of rigorous investment research and analytical tools, along with conservative portfolio construction used to identify appropriate non-cyclical energy infrastructure company investments, provides a value added service to the individual investor making an investment in this asset class.

The Fund may also use derivative investments such as bond index and equity index futures to hedge against interest rate and market risks. The Fund may engage in currency hedging transactions, including buying or selling options or entering into other transactions including futures, forward contracts, swaps and other derivatives transactions.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

CANADA RISK. The Fund is subject to certain risks specifically associated with investments in the securities of Canadian issuers. The Canadian economy is heavily dependent on the demand for natural resources and agricultural products. Canada is a major producer of commodities such as forest products, metals, agricultural products, and energy related products like oil, gas, and hydroelectricity. Accordingly, a change in the supply and demand of these resources, both domestically and internationally, can have a significant effect on Canadian market performance. Canada is a top producer of zinc and uranium and a global source of many other natural resources, such as gold, nickel, aluminum, and lead. Conditions that weaken demand for such products worldwide could have a negative impact on the Canadian economy as a whole. Changes to the U.S. economy may significantly affect the Canadian economy because the United States is Canada’s largest trading partner and foreign investor. These and other factors could have a negative impact on the Fund and its investments in Canada.

CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning.

may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

ENERGY INFRASTRUCTURE COMPANIES RISK. Energy infrastructure companies, including MLPs and utility companies, are subject to risks specific to the energy and energy-related industries. This includes but is not limited to: fluctuations in commodity prices impacting the volume of energy commodities transported, processed, stored or distributed; reductions in volumes of natural gas or other energy commodities being available for transporting, processing, storing or distributing; slowdowns in new construction and acquisitions limiting growth potential; reduced demand for oil, natural gas and petroleum products, particularly for a sustained period of time; depletion of natural gas reserves or other commodities; rising interest rates resulting in higher costs of capital, increased operating costs; counterparties to contracts defaulting or going bankrupt; and an inability to execute acquisitions or expansion projects in a cost-effect manner; extreme weather events and environmental hazards; and threats of attack by terrorists on energy assets. Energy infrastructure companies may also face counterparty risk, such that long-term contracts may be declared void if the counterparty to those contracts enters bankruptcy proceedings. In addition, energy infrastructure companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of energy infrastructure companies. Natural disasters, such as hurricanes in the Gulf of Mexico, also may impact the energy infrastructure companies.

Certain energy infrastructure companies in the utilities industry are subject to the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations, and the capital market’s ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for these companies. Such issuers have been experiencing certain of these problems in varying degrees.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

MLP RISK. Investments in securities of MLPs involve certain risks different from or in addition to the risks of investing in common stocks. MLP common units can be affected by macro-economic factors and other factors unique to the partnership or company and the industry or industries in which the MLP operates. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and illiquidity. The structures of MLPs create certain risks, including, for example, risks related to the limited ability of investors to control an MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require unit-holders to sell their common units at an undesirable time or price. On March 15, 2018, the Federal Energy Regulatory Commission (“FERC”) changed its long-standing tax allowance policy which no longer permits MLPs to include in their cost of service an income tax allowance. This has had a negative impact on the performance of some MLPs affected by this decision. This policy change and any similar policy changes in the future could adversely impact an MLP’s business, financial condition, results of operations and cash flows and ability to pay cash distributions or dividends.

MLP TAX RISK. The Fund’s ability to meet its investment objective relies in part upon the level of taxable income it receives from the MLPs in which it invests, a factor over which the Fund has no control. The benefit the Fund derives from its investment in MLPs is largely dependent on their being treated as partnerships for U.S. federal income tax purposes. Partnerships do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or a change in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in the MLP being required to pay U.S. federal income tax (as well as state and local income taxes) on its taxable income at the applicable corporate tax rate. This would have the effect of reducing the amount of cash available for distribution by an MLP and could result in a significant reduction in the value of the Fund’s investment. The classification of an MLP as a corporation for U. S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP’s current or accumulated earnings and profits. To the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in the amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Furthermore, any return of capital distribution received from an MLP may require the Fund to restate the character of its distributions and amend any shareholder tax reporting previously issued.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the Investment Act of 1940, as amended (the "1940 Act"). As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

SMALLER COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

UTILITY COMPANIES RISK. Utility companies include companies producing or providing gas, electricity or water. These companies are subject to the risk of the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects counterparty risk, the limitations on operations and increased costs and delays attributable to environmental considerations and the capital market’s ability to absorb utility debt. In addition, taxes, government regulation, domestic and international politics, price and supply fluctuations, volatile interest rates and energy conservation may negatively affect utility companies.

The Blended Benchmark consists of the following two indices: 50% of the PHLX Utility Sector Index, which is a market capitalization-weighted index composed of geographically diverse public U.S. utility stocks; and 50% of the Alerian MLP Total Return Index which is a float-adjusted, capitalization-weighted composite of the most prominent energy MLPs. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.

Additional Information on the Fund’s Strategy

The Sub-Advisor believes that a professionally managed portfolio of higher dividend paying energy infrastructure companies in non-cyclical segments offers an attractive balance of income and growth. The Sub-Advisor’s priority is to focus on steady fee-for-service income and will limit the cyclical energy exposure of the portfolio in order to reduce the volatility of returns. The Sub-Advisor believes the use of rigorous investment research and analytical tools along with conservative portfolio construction provides a value added service to the individual investor making an investment in these asset classes.

The Sub-Advisor believes that successful investing in the energy infrastructure industry requires strict capital spending discipline because the industry is capital intensive, mature and has low rates of overall growth. The Sub-Advisor believes there is a high correlation between rates of return and the portion of cash flow reinvested in the business—the lower the level of reinvestment, the higher the return. Capital spending discipline can result from careful prudent management or an agreement with shareholders to pay out most available free cash flow. The Sub-Advisor believes that companies paying out a large portion of their available free cash flow in the form of monthly or quarterly distributions or dividends—such as MLPs in the U.S. and certain pipeline companies and utilities in the U.S. and Canada—have a built-in capital spending discipline and provide an attractive investment universe from which to construct a portfolio. While growth opportunities are still available to these companies, they must go to the capital markets and justify to yield-sensitive shareholders the issuance of more equity and debt in order to fund those opportunities. The Sub-Advisor believes that this transparency tends to discourage acquisitions and new construction that would be dilutive to the dividend paying capability on existing shares and tends to encourage expenditures that are accretive.

A high-payout ratio, however, brings with it an income obligation that the Sub-Advisor believes is matched by an expectation on the part of the shareholders that such dividends will be steady. Retail investors that make up the bulk of the shareholder base of these securities have punished the share prices of MLPs and similar securities when dividends or distributions have been cut or eliminated. The Sub-Advisor believes that the assets that best support a high-payout ratio are those with steady, fee-for-service businesses with relatively low sustaining capital obligations. In the energy infrastructure industry, assets such as interstate pipelines, intrastate pipelines with long-term contracts, power generation assets, storage and terminal facilities with long-term contracts and regulated power transmission and distribution assets are the types of assets that fit best. By contrast, other areas of the energy industry such as oil and gas exploration, development and production are less well suited because the cash flows are cyclical in nature, being driven by commodity prices, and because oil and gas assets are wasting assets, while the dividend obligation is perpetual.

Unlike oil and gas exploration, development and production and petroleum refining, the energy infrastructure industry is characterized by non-cyclical fee-for-service revenues. Also, unlike the other segments of the energy industry, the sustaining capital requirements for pipelines, storage and other infrastructure is low. The Sub-Advisor believes that these two characteristics make energy infrastructure assets a good match for investors who desire steady income that has the ability to grow.

Much of the pipeline and storage infrastructure currently owned by energy infrastructure companies were built many years ago by the major oil companies and pipeline and power utilities. Over the years, these assets have been sold off to fund projects with higher risk such as oil drilling, unregulated power generation or energy trading. The result is that the legacy assets, many of which are natural monopolies, can now be owned as pure plays in the energy infrastructure asset classes.

As oil and gas production in the U.S. continues to rise, new technologies have made long known resources economic, even at lower prices. The resulting higher margins for oil and gas drilling have made the oil and gas production companies more willing to guarantee solid returns for long-term contracts to pipeline owners as an incentive to add capacity so they can deliver their oil and gas to market more quickly. In essence, energy infrastructure companies have an increased ability to “lock-in” the attractive economics of today’s energy industry.

The Fund may invest in equity securities of MLPs without limit, however, in order to comply with applicable tax diversification rules, the Fund may have to limit the percentage of its nets assets invested in MLPs on a periodic basis. The Sub-Advisor believes that this investment opportunity is difficult for many large investors to take advantage of, which has left these securities largely in the hands of retail investors. Non-taxable investors, such as pension funds and endowments, have not historically owned significant portions of these securities because MLPs can generate a substantial amount of “unrelated business taxable income,” or UBTI, which can be disadvantageous to such institutions. In addition, for tax years beginning on or before October 22, 2004, MLPs represented non-qualifying income for mutual funds.

The Sub-Advisor has many years of experience investing in the energy sector. Combined, the Energy Income Partners Investment Team has over 180 years of experience in the energy industry, investment research, commodity trading and portfolio management. The Sub-Advisor believes that investment success in the energy infrastructure industry requires a working knowledge of the entire energy industry. In essence, it is the businesses the pipelines connect to, much more than the pipe itself, that determines financial success. That means knowledge of the oil and gas segment, refining and marketing, petrochemicals and natural gas processing and storage. It also means understanding price and cost competitiveness of competing fuels such as coal and nuclear as well as the impact of imports and global markets in the North American energy industry.

In addition, the Sub-Advisor believes that the attractive characteristics of the energy infrastructure business can be materially enhanced by a rigorous application of investment research and portfolio construction tools. There is generally less research coverage of these companies than in other sectors of comparable size whose securities are owned by institutional investors. The Sub-Advisor believes this creates an opportunity to outperform the sector using such investment research and portfolio construction tools. Since the companies in this asset class are affected by virtually every phase of the energy business (even if they are not directly invested in every phase), the Sub-Advisor believes it is necessary to have a strong working knowledge of the business including oil and gas production and gathering, transportation, refining and marketing, gas liquids processing and fractionation, petrochemical demand and cost structure as well as the regulatory framework that regulates the industry.

Fund Investments

Principal Investments

Equity Securities

Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by the Sub-Advisor to be engaged in the energy infrastructure sector. Equity securities include common stocks; preferred securities; warrants to purchase common stocks or preferred securities; securities convertible into common stocks or preferred securities; master limited partnership ("MLP") units and MLP I-units discussed below and other securities with equity characteristics.

If the Fund’s investment in qualifying MLPs exceeds 25% of the value of the Fund’s total assets at the end of any quarter in which the Fund is required to test its diversification, the Fund may not qualify as a regulated investment company for federal income tax purposes unless the Fund takes corrective measures within 30 days of the end of the quarter.

Master Limited Partnerships

The Fund may invest in equity securities of MLPs without limit, however, in order to comply with applicable tax diversification rules, the Fund may have to limit the percentage of its nets assets invested in MLPs on a periodic basis. As of the date of this prospectus, this limit is 25% of the Fund’s assets on a quarterly basis.

MLPs are limited partnerships whose shares (or units) are listed and traded on a U.S. securities exchange, just like common stock. To qualify as an MLP, a partnership must receive at least 90% of its income from qualifying sources such as natural resource activities. Natural resource activities include the exploration, development, mining, production, processing, refining, transportation, storage and marketing of mineral or natural resources. MLPs generally have two classes of owners, the general

partner and limited partners. The general partner, which is generally a major energy company, investment fund or the management of the MLP, typically controls the MLP through a 2% general partner equity interest in the MLP plus common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership’s operations and management.

MLPs are typically structured such that common units have first priority to receive quarterly cash distributions up to an established minimum quarterly dividend (“MQD”). Common units also accrue arrearages in distributions to the extent the MQD is not paid. Once common units have been paid, subordinated units receive distributions of up to the MQD, but subordinated units do not accrue arrearages. Distributable cash in excess of the MQD paid to both common and subordinated units is distributed to both common and subordinated units generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner which maximizes value to unit holders. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions. A common arrangement provides that the general partner can reach a tier where the general partner is receiving 50% of every incremental dollar paid to common and subordinated unit holders. By providing for incentive distributions the general partner is encouraged to streamline costs and acquire assets in order to grow the partnership, increase the partnership’s cash flow, and raise the quarterly cash distribution in order to reach higher tiers. Such results benefit all security holders of the MLP.

MLP I-Shares

I-Shares represent an ownership interest issued by an affiliated party of an MLP. The MLP affiliate uses the proceeds from the sale of I-Shares to purchase limited partnership interests in the MLP in the form of i-units. I-units have similar features as MLP common units in terms of voting rights, liquidation preference and distributions. However, rather than receiving cash, the MLP affiliate receives additional i-units in an amount equal to the cash distributions received by MLP common units. Similarly, holders of I-Shares will receive additional I-Shares, in the same proportion as the MLP affiliates’ receipt of i-units, rather than cash distributions. I-Shares themselves have limited voting rights which are similar to those applicable to MLP common units. The MLP affiliate issuing the I-Shares is structured as a corporation for federal income tax purposes. As a result, I-Shares holders, such as the Fund, will receive a Form 1099 rather than a Form K-1 statement. I-Shares are traded on the New York Stock Exchange.

Non-U.S. Investments

The Fund may invest in U.S. dollar-denominated depositary receipts, U.S. dollar-denominated foreign securities and non-U.S. dollar-denominated foreign securities. The Fund’s investments may include American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”).

The Fund may invest in non-U.S. securities, which may include securities denominated in U.S. dollars or in non-U.S. currencies. Because evidences of ownership of such securities usually are held outside the United States, the Fund would be subject to additional risks if it invested in non-U.S. securities, which include possible adverse political and economic developments, seizure or nationalization of foreign deposits and adoption of governmental restrictions which might adversely affect or restrict the payment of distributions on the non-U.S. securities to investors located outside the country of the issuer, whether from currency blockage or otherwise. Since non-U.S. securities may be purchased with and payable in foreign currencies, the value of these assets as measured in U.S. dollars may be affected favorably or unfavorably by changes in currency rates and exchange control regulations

Non-Principal Investments

Cash Equivalents and Short-Term Investments

Normally, the Fund invests substantially all of its assets to meet its investment objective. The Fund may invest in securities with maturities of less than one year or cash equivalents, or it may hold cash. The percentage of the Fund invested in such holdings varies and depends on several factors, including market conditions. For temporary defensive purposes and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities or it may hold cash. During such periods, the Fund may not be able to achieve its investment objective. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the SAI.

Derivatives

The Fund may use futures, total return swaps, non-U.S. currency swaps, credit default swaps, options and other derivative instruments to seek to enhance return, to hedge some of the risks of its investments in securities, as a substitute for a position in the underlying asset, to reduce transaction costs, to maintain full market exposure (which means to adjust the characteristics of their investments to more closely approximate those of the markets in which it invests), to manage cash flows, to limit exposure to losses due to changes to non-U.S. currency exchange rates or to preserve capital.

The Fund will comply with the regulatory requirements of the Securities and Exchange Commission and the Commodity Futures Trading Commission with respect to coverage of options and futures positions by registered investment companies and, if the guidelines so require, will earmark or set aside cash, U.S. Government securities, high grade liquid debt securities and/or other liquid assets permitted by the Securities and Exchange Commission and Commodity Futures Trading Commission in a segregated custodial account in the amount prescribed (or take such other actions permitted by law). Securities earmarked or held in a segregated account cannot be sold while the futures or options position is outstanding, unless replaced with other permissible assets, and will be marked to market daily.

The Fund may sell covered call options, which enables the purchaser to elect to receive a security at a predetermined price and time. A call option written by the Fund on a security is “covered” if the Fund owns the security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration (or for consideration that is set aside or earmarked) upon conversion or exchange of other securities held by the Fund. A call option is also covered if the Fund holds a call on the same security as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated assets. Without limiting the foregoing, the Fund may use other derivatives from time to time and other methods of segregation or cover as permitted by applicable law.

Investment Companies

The Fund may invest in securities of other investment companies, including exchange-traded funds (“ETFs”), that invest primarily in securities of the types in which the Fund may invest directly. As a shareholder in an investment company, the Fund bears its ratable share of such investment company’s expenses and would remain subject to payment of the investment company’s advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed-end investment companies. Securities of other investment companies may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile than securities of unleveraged securities.

The Fund’s ability to invest in other investment companies is limited by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) and 12(d)(1)(G). The Fund may satisfy the Name Policy by investing in investment companies and other pooled investment vehicles that are subject to a comparable name policy and invest in the types of securities in which the Fund may invest directly.

Illiquid Securities

Disclosure of Portfolio Holdings

Risks of Investing in the Fund

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CANADA RISK. The Fund invests significantly in the securities of Canadian issuers. The Canadian economy is heavily dependent on the demand for natural resources and agricultural products. Canada is a major producer of commodities such as forest products, metals, agricultural products, and energy related products like oil, gas, and hydroelectricity. Accordingly, a change in the supply and demand of these resources, both domestically and internationally, can have a significant effect on Canadian market performance. Canada is a top producer of zinc and uranium and a global source of many other natural resources, such as gold, nickel, aluminum, and lead. Conditions that weaken demand for such products worldwide could have a negative impact on the Canadian economy as a whole. The Canadian economy is heavily dependent on relationships with certain key trading partners. The United States is Canada’s largest trading and investment partner, and the Canadian economy is significantly affected by developments in the U.S. economy. Any downturn in U.S. economic activity is likely to have an adverse impact on the Canadian economy.

CURRENCY RISK. The Fund may invest in securities denominated in a non-U.S. currency. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, the value of dividends and interest earned from such securities and gains and losses realized on the sale of such securities. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. Changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. An increase in the strength of the U.S. dollar relative to other currencies may cause the value of the Fund to decline. Certain non-U.S. currencies may be particularly volatile, and non-U.S. governments may intervene in the currency markets, causing a decline in value or liquidity in the Fund's non-U.S. holdings whose value is tied to the affected non-U.S. currency. Additionally, the prices of non-U.S. securities that are traded in U.S. dollars are often indirectly influenced by currency fluctuations.

identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. However, there is no guarantee that such efforts will succeed, and the Fund and its shareholders could be negatively impacted as a result.

ENERGY INFRASTRUCTURE COMPANIES RISK. The Fund invests significantly in energy infrastructure companies. Energy infrastructure companies are subject to risks specific to the energy and energy-related industries. This includes but is not limited to: fluctuations in commodity prices impacting the volume of energy commodities transported, processed, stored or distributed; reductions in volumes of natural gas or other energy commodities being available for transporting, processing, storing or distributing; slowdowns in new construction and acquisitions limiting growth potential; reduced demand for oil, natural gas and petroleum products, particularly for a sustained period of time; depletion of natural gas reserves or other commodities; rising interest rates resulting in higher costs of capital, increased operating costs and an inability to execute acquisitions or expansion projects in a cost-effect manner; extreme weather events and environmental hazards; and threats of attack by terrorists on energy assets. In addition, energy infrastructure companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Energy infrastructure companies may also face counterparty risk such that long term contracts may be declared void if the counterparty to those contracts enters into bankruptcy proceedings. Energy infrastructure companies that own interstate pipelines are subject to regulation by FERC with respect to the tariff rates they may charge for transportation services. An adverse determination by FERC with respect to the tariff rates of such a company could have a material adverse effect on its business, financial condition, results of operations and cash flows and its ability to pay cash distributions or dividends. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of energy infrastructure companies. Certain energy infrastructure companies in the utilities industry are subject to the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations, and the capital market’s ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for these companies. Such issuers have been experiencing certain of these problems to varying degrees.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests.Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

MLP RISK. Investments in securities of MLPs involve certain risks different from or in addition to the risks of investing in common stocks, including for example risks related to the limited ability of investors to control an MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require investors to sell their common units at an undesirable time or price. MLP common units can be affected by macro-economic and other factors affecting the stock market in general, changes or anticipated changes in interest rates, investor sentiment towards MLPs or the energy sector generally, changes in a particular issuer's financial condition, or unfavorable or unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms of distributable cash flow). Prices of common units of individual MLPs also can be affected by other factors unique to the partnership or company, including earnings power and coverage ratios. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and lack sufficient market liquidity to enable the Fund to effect a sale at an advantageous time or price. Because many MLPs pay out most of their operating cash flows, the MLPs rely on capital markets for access to equity and debt financing to fund growth through organization. If market conditions limit an MLPs access to capital markets, the MLPs growth prospects could diminish and its costs of capital increase, which would decrease the value of the common units held by the Fund. MLPs are now a higher cost way of financing these industries; the reverse of the conditions that led to the growth of the asset class in the early part of the last decade. As a result, the industry is witnessing the consolidation or simplification of corporate structures where the MLP sleeve of capital is being eliminated because it no longer reduces a company’s cost of equity financing. Even for MLPs that have avoided exposure to commodity prices and have been successful in growing their dividends, the cost of the MLP structure has risen due to growing incentive payments to the general partner. These incentives increase with per share dividend growth at the limited partnership level and are due on newly issued shares, as well as older shares that have experienced the growth. As a result, the more successful the MLP is in growing its dividends, the closer it gets to paying incentives to the parent/general partner that are more onerous than a tax at the corporate level. The lower the corporate tax rate, the sooner this threshold is crossed. In many cases, MLPs are merely a part of the corporate finance structure of a company. MLPs are created when they lower the cost of equity financing and are no longer used when they do not. MLPs that own

interstate pipelines are subject to FERC regulation with respect to tariffs charged and received an adverse decision. On March 15, 2018, the FERC changed its long-standing tax allowance policy which no longer permits MLPs to include in their cost of service an income tax allowance. This had a negative impact on the performance of some MLPs affected by this decision. This policy change and any similar policy changes in the future could adversely impact an MLP’s business, financial condition, results of operations and cash flows and ability to pay cash distributions or dividends.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds and may be more sensitive to any single economic, business, political or regulatory occurrence than a diversified fund. To the extent the Fund invests in a relatively small number of issuers due to the high percentage of the Fund’s assets invested in that security, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds.

from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

SMALLER COMPANIES RISK. The Fund invests in the securities of small and/or mid capitalization companies. The stock price of small and/or mid capitalization companies may be more volatile than those of larger companies and therefore the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large capitalization companies. Stock prices of small and/or mid capitalization companies are also generally more vulnerable than those of large capitalization companies to adverse business and economic developments. Securities of small and/or mid capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small and/or mid capitalization companies are typically less financially stable than larger, more established companies and may reinvest a high proportion of their earnings in their business and may not pay dividends. Small and/or mid capitalization companies may also depend on a small number of essential personnel who may also be less experienced than the management of larger companies, making these companies more vulnerable to experiencing adverse effects due to the loss or inexperience of personnel. Small and/or mid capitalization companies also normally have less diverse product lines than those of large capitalization companies and are more susceptible to adverse developments concerning their products.

UTILITY COMPANIES RISK. The Fund invests significantly in utility companies. Utility companies include companies producing or providing gas, electricity or water. The risks inherent in the utility sector include a variety of factors that may adversely affect the business or operations of utility companies, including: high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital on reasonable terms in periods of high inflation and unsettled capital markets; governmental regulation of rates that the issuer can charge to customers; costs associated with compliance with, and adjusting to changes to, environmental and other regulations; counterparty risk; effects of economic slowdowns and surplus capacity; increased competition from other providers of utility services; costs associated with the reduced availability of certain types of fuel, occasionally reduced availability and high costs of natural gas for resale, and the effects of energy conservation policies. Some utility companies also face risks associated with the effects of a national energy policy and lengthy delays, and greatly increased costs and other problems, associated with the design, construction, licensing, regulation and operation of nuclear facilities for electric generation, including, among other considerations: the problems associated with the use of radioactive materials and the disposal of radioactive wastes; technological innovations that may render existing plants, equipment or products obsolete; difficulty in obtaining regulatory approval of new technologies; lack of compatibility of telecommunications equipment; potential impacts of terrorist activities on the utility industry and its customers; and the impact of natural or man-made disasters. Utility companies may also be subject to regulation by various governmental authorities and may be affected by the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. Deregulation is subjecting utility companies to greater competition and may adversely affect profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. There is no assurance that regulatory authorities will, in the future, grant rate increases, or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company.

Non-Principal Risks

of low demand or decreased liquidity, such borrowings might be outstanding for longer periods of time. As prescribed by the 1940 Act, the Fund will be required to maintain specified asset coverage of at least 300% with respect to any bank borrowing immediately following such borrowing and at all times thereafter. The Fund may be required to dispose of assets on unfavorable terms if market fluctuations or other factors reduce the Fund’s asset coverage to less than the prescribed amount.

CASH TRANSACTIONS RISK. The Fund may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A Fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

DEFERRED TAX RISK. As a limited partner in the MLPs in which it invests, the Fund will be allocated its pro rata share of income, gains, losses, deductions and expenses from the MLPs. A significant portion of MLP income has historically been offset by tax deductions. The Fund will recognize income with respect to that portion of a distribution that is not offset by tax deductions, with the remaining portion of the distribution being treated as a tax-deferred return of capital. The percentage of an MLP’s distribution which is offset by tax deductions will fluctuate over time for various reasons. A significant slowdown in acquisition or investment activity by MLPs held in the Fund’s portfolio could result in a reduction of accelerated depreciation or other deductions generated by these activities, which may result in increased net income to the Fund. A reduction in the percentage of the income from an MLP offset by tax deductions or gains as a result of the sale of portfolio securities will reduce that portion, if any, of the Fund’s distribution treated as a tax-deferred return of capital and increase that portion treated as dividend income, resulting in lower after-tax distributions to the Fund’s shareholders. The Fund will rely to some extent on information provided by MLPs, which is usually not timely, to determine the tax character of the distributions to shareholders.

DEPENDENCE ON KEY PERSONNEL RISK. The Sub-Advisor is dependent upon the experience and expertise of the Fund’s portfolio managers in providing advisory services with respect to the Fund’s investments. If the Sub-Advisor were to lose the services of any of these portfolio managers, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for any of the portfolio managers in the event of their death, resignation, retirement or inability to act on behalf of the Sub-Advisor.

DEPOSITARY RECEIPTS RISK. The Fund invests in depositary receipts. Depository receipts are securities issued by a bank or trust company reflecting ownership of underlying securities issued by a foreign company. An investment in depositary receipts involves further risks due to certain unique features. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights pursuant to a deposit agreement between the underlying issuer and the depositary. In certain cases, the depositary will vote the shares deposited with it as directed by the underlying issuer’s board of directors. Furthermore, investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert shares into depositary receipts and vice versa. Such restrictions may cause shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipt. Moreover, if depositary receipts are converted into shares, the laws in certain countries may limit the ability of a non-resident to trade the shares and to reconvert the shares to depositary receipts. Depositary receipts may be “sponsored” or “unsponsored.” Sponsored depositary receipts are established jointly by a depositary and the underlying issuer, whereas unsponsored depositary receipts may be established by a depositary without participation by the underlying issuer. Holders of unsponsored depositary receipts generally bear all the costs associated with establishing the unsponsored depositary receipts. In addition, the issuers of the securities underlying unsponsored depositary receipts are not obligated to disclose material information in the U.S. and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts.

FAILURE TO QUALIFY AS A REGULATED INVESTMENT COMPANY RISK. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. In such circumstances, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment. If the Fund fails to qualify as a regulated investment company, distributions to the Fund's shareholders generally would be eligible (i) for treatment as qualified dividend income in the case of individual shareholders and (ii) for the dividends received deduction in the case of corporate shareholders.

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund may trade on non-U.S. exchanges that are closed when the Fund's primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market), resulting in premiums or discounts to the Fund's net asset value that may be greater than those experienced by other exchange-traded funds. However, because shares can be created and redeemed in Creation Units at a Fund's net asset value, it is not expected that large discounts or premiums to the net asset value of the Fund will be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values).

Fund Organization

The Fund is a series of the Trust, an investment company registered under the 1940 Act. The Fund is treated as a separate fund with its own investment objective and policies. The Trust is organized as a Massachusetts business trust. The Board is responsible for the overall management and direction of the Trust. The Board elects the Trust’s officers and approves all significant agreements, including those with the Advisor, Sub-Advisor, custodian and fund administrative and accounting agent.

How to Buy and Sell Shares

For purposes of the 1940 Act, the Fund is treated as a registered investment company, and, absent an available exemption or exemptive relief, the acquisition of shares by other registered investment companies and companies relying on Sections 3(c)(1) and 3(c)(7) of the 1940 Act is subject to the restrictions of Section 12(d)(1) of the 1940 Act. The Trust, on behalf of the Fund, has received an exemptive order from the Securities and Exchange Commission that permits certain registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that any such investment companies enter into an agreement with the Fund regarding the terms of any investment.

Dividends, Distributions and Taxes

Dividends from net investment income from the Fund, if any, are declared and paid quarterly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Due to the tax treatment under current law of cash distributions made by MLPs in which the Fund invests, a portion of the distributions the Fund anticipates making may consist of tax-deferred return of capital. To the extent that distributions exceed such Fund’s earnings and profits, distributions are generally not treated as taxable income for the investor. Instead, Fund shareholders will experience a reduction in the basis of their shares, which may increase the capital gain or reduce capital loss, realized upon the sale of such shares. Thus, if the Fund’s capital was the source of a distribution and the payment amounted to a return of capital, the Fund would be required to provide a written notice to that effect. A “return of capital” represents a return on a shareholder’s original investment in the Fund, and should not be confused with a dividend from earnings and profits. Upon the sale of Fund shares, shareholders generally will recognize capital gain or loss measured by the difference between the sale proceeds received by the shareholder and the shareholder’s federal income tax basis in shares sold, as adjusted to reflect return of capital.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

The Fund intends to continue to qualify as a “regulated investment company” under the federal tax laws. If the Fund qualifies as a regulated investment company and distributes its income as required by the tax law, the Fund generally will not pay federal income taxes. An adverse federal income tax audit of a partnership that the Fund invests in could result in the Fund being required to pay federal income tax or pay a deficiency dividend (without having received additional cash).

Distributions

The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate, however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A "return of capital" is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

If you are an individual, the maximum marginal stated federal tax rate for net capital gain is generally 20% (15% or 0% for taxpayers with taxable incomes below certain thresholds). Some capital gains, including some portion of your capital gain dividends may be taxed at a higher maximum stated tax rate. Some portion of your capital gain dividends may be attributable to the Fund’s interest in a master limited partnership which may be subject to a maximum marginal stated federal tax rate of 28%, rather than the rates set forth above. In the case of capital gain dividends, the determination of which portion of the capital gain dividend, if any, is subject to the 28% tax rate, will be made based on rules prescribed by the United States Treasury. Capital gains may also be subject to the Medicare tax described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Because the Fund may invest in non-U.S. securities, the tax statement that you receive may include an item showing non-U.S. taxes the Fund paid to other countries. In this case, dividends taxed to you will include your share of the taxes the Fund paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes.

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Distributions may be subject to a U.S. withholding tax of 30% in the case of distributions to (i) certain non-U.S. financial institutions that have not entered into an agreement with the U.S. Treasury to collect and disclose certain information and are not resident in a jurisdiction that has entered into such an agreement with the U.S. Treasury and (ii) certain other non-U.S. entities that do not provide certain certifications and information about the entity’s U.S. owners. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

Investments in Certain Non-U.S. Corporations

rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such passive foreign investment company shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from passive foreign investment companies and its proceeds from dispositions of passive foreign investment company stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by passive foreign investment companies are not treated as qualified dividend income.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board or its delegate, the Advisor’s Pricing Committee, at fair value. The use of fair value pricing by the Fund is governed by valuation procedures adopted by the Board and in accordance with the provisions of the 1940 Act. These securities generally include, but are not limited to, certain restricted securities (securities which may not be publicly sold without registration under the Securities Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s net asset value or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from the current market valuations. See the Fund’s SAI for details.

Principal Investment Strategies

Under normal market conditions, the Fund seeks to outperform each of the LL100 and MI100 (as defined below) by investing at least 80% of its net assets (including investment borrowings) in first lien senior floating rate bank loans (“Senior Loans”). The S&P/LSTA U.S. Leveraged Loan 100 Index (the “LL100”) is a market value-weighted index designed to measure the performance of the largest segment of the U.S. syndicated leveraged loan market. The LL100 consists of 100 loan facilities drawn from a larger benchmark, the S&P/LSTA Leveraged Loan Index. The Markit iBoxx USD Liquid Leveraged Loan Index (the “MI100”) selects the 100 most liquid Senior Loans in the market. The Fund does not seek to track either the LL100 or MI100, but rather seeks to outperform each of the indices. It is anticipated that the Fund, in accordance with its principal investment strategy, will invest approximately 50% to 75% of its net assets in Senior Loans that are eligible for inclusion in and meet the liquidity thresholds of the LL100 and/or MI100 at the time of investment.

A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions to one or more corporations, partnerships or other business entities and typically pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate, most commonly the London Interbank Offered

Rate (“LIBOR”). A Senior Loan is considered senior to all other unsecured claims against the borrower, senior to or equal with all other secured claims, meaning that in the event of a bankruptcy of the borrower the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing unsecured claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence.

The Fund may invest significantly in “covenant-lite” loans, which are loans issued with fewer restrictions on collateral, payment terms and level of income. Traditional loans generally have protective covenants built into the contract to protect the lender, including financial maintenance tests that measure the debt-service capabilities of the borrower; however, covenant-lite loans lack many of these lender protection provisions. Covenant-lite loans carry more risk than traditional loans and allow borrowers to engage in activities that would be difficult or impossible under a traditional loan agreement. The lack of traditional lender protection provisions contained in covenant-lite loans may impact recovery values and/or trading levels in the future.

The Fund invests in Senior Loans made predominantly to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. The Fund may invest in Senior Loans directly, either from the borrower as part of a primary issuance or in the secondary market through assignments of portions of Senior Loans from third parties, or participations in Senior Loans, which are contractual relationships with an existing lender in a loan facility whereby the Fund purchases the right to receive principal and interest payments on a loan but the existing lender remains the record holder of the loan. The Senior Loans included in the Fund’s portfolio often maintain a duration of less than 90 days; however, the inclusion of LIBOR floors on certain Senior Loans or other factors may cause interest rate duration to be longer than 90 days.

When identifying prospective investment opportunities in Senior Loans, First Trust Advisors L.P., the Fund’s investment advisor, currently intends to invest primarily in Senior Loans that are below investment grade quality at the time of investment, and relies on fundamental credit analysis in an effort to attempt to minimize the loss of the Fund’s capital and to select assets that provide attractive relative value. Securities rated below investment grade, commonly referred to as “junk” or “high yield” securities, include securities that are rated Ba1/BB+/BB+ or below by Moody’s Investors Service, Inc. (“Moody’s”), Fitch Inc., or Standard & Poor’s, Inc. (“S&P”), respectively. The Fund may invest in securities of any rating. The Fund may also invest in unrated securities deemed by the investment advisor to be of comparable quality to those securities rated below investment grade.

The Fund may also invest up to 20% of its net assets in (1) non-Senior Loan debt securities, which may be fixed-rate or floating-rate income-producing securities (including, without limitation, U.S. government debt securities and corporate debt securities, which may include convertible bonds), (2) warrants, U.S. and non-U.S. equity and equity-like positions and interests and other securities issued by or with respect to a borrower or its affiliates, and/or (3) securities of other investment companies. In addition, the Fund may invest up to 15% of its net assets in Senior Loans and/or other floating rate loans that are distressed or in default.

The Fund’s investment advisor combines a fundamental credit selection process with relative value analysis and top-down macroeconomic perspectives when selecting investment opportunities. The Fund’s investment advisor believes that an evolving investment environment offers varying degrees of investment risk opportunities in the bank loan, high yield and other fixed income instrument markets. To capitalize on attractive investments and effectively manage potential risk, the Fund’s investment advisor believes that the combination of thorough and continuous credit analysis, market evaluation, diversification and the ability to reallocate investments is critical to achieving higher risk-adjusted returns.

Principal Risks

BANK LOANS RISK. Investments in bank loans are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk that may be heightened because of the limited public

information available regarding bank loans and because loan borrowers may be leveraged and tend to be more adversely affected by changes in market or economic conditions. If the Fund holds a bank loan through another financial institution or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. It is possible that any collateral securing a loan may be insufficient or unavailable to the Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for bank loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods (in some cases longer than 7 days) which may cause the Fund to be unable to realize the full value of its investment. In addition, bank loans are generally not registered with the Securities Exchange Commission under the Securities Act of 1933, as amended, and may not be considered “securities,” and the Fund may not be entitled to rely on the anti-fraud protections of the federal securities laws.

COVENANT-LITE LOANS RISK. There may be instances in which the Fund invests in covenant-lite loans. Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle.

securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SENIOR LOAN RISK. Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by a lien on all or some portion of the assets of the borrower. The senior loan market has seen a significant increase in loans with weaker lender protections including, but not limited to, limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan agreement and general weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions. Weaker lender protections such as the absence of financial maintenance covenants in a loan agreement and the inclusion of “borrower-favorable” terms may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may not be able to declare a default if financial performance deteriorates. This may hinder the Fund’s ability to reprice credit risk associated with a particular borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell its position in a senior loan and which may make it difficult to accurately value senior loans. Lastly, senior loans may not be considered “securities,” and the Fund may not be entitled to rely on the anti-fraud protections of the federal securities laws.

Additional Information on the Fund's Investment Objectives and Strategies

The Fund is a series of First Trust Exchange-Traded Fund IV and is regulated as an “investment company” under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objectives are fundamental and may not be changed without approval by the holders of a majority of the outstanding voting securities of the Fund. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. If there is a material change to the Fund’s principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objectives.

The Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”), whereby the Fund, under normal market conditions, invests at least 80% of its net assets (including investment borrowings) in Senior Loans. The Name Policy may be changed by the Board without shareholder approval upon 60 days’ prior written notice.

Additional Information on the Fund’s Strategy

When identifying prospective investment opportunities in Senior Loans, the Advisor intends to invest primarily in Senior Loans that are below investment grade quality at the time of investment, and will rely on fundamental credit analysis in an effort to attempt to minimize the loss of the Fund’s capital. As a general matter, the Advisor seeks to invest in Senior Loans or other debt of companies possessing some or all of the attributes described below, which it believes will help generate higher risk-adjusted total returns:

•

Senior Loans or other debt of companies that have developed strong positions within their respective markets and exhibit the potential to maintain sufficient cash flows and profitability to service their obligations in a range of economic environments.

•

Senior Loans or other debt of companies that possess advantages in scale, scope, customer loyalty, product pricing or product quality versus their competitors, thereby minimizing business risk and protecting profitability.

•

Senior Loans or other debt of established companies that have demonstrated a record of profitability and cash flows over several economic cycles.

•

Senior Loans or other debt of a target company that has an experienced management team with an established track record of success.

The Advisor seeks to invest in a portfolio of Senior Loans or other debt among various borrowers and industries, thereby potentially reducing the risk of a downturn in any one company or industry having a disproportionate impact on the value of the Fund’s holdings. Loans, and the collateral securing them, are typically monitored by agents for the lenders, which may be the originating bank or banks.

Senior Loans

Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by a lien on all or some portion of the assets of the borrower. These loans are often arranged by a syndicate of banks to refinance a borrower’s existing debt, to finance acquisitions, dividends, leveraged buyouts, and for general corporate purposes. Senior loans may be acquired by the Fund in whole or through the purchase of a participation. Senior loans rank at the top of a borrower’s capital structure in terms of priority of payment, ahead of any subordinated debt or the borrower’s preferred or common equity. These loans are often secured, as the holders of these loans typically hold or share a first lien priority on most if not all of the corporate borrower’s plant, property, equipment, receivables, cash balances, licenses, trademarks, etc. Senior loans typically pay interest at rates which are determined periodically on the basis of a floating base lending rate, primarily the LIBOR, plus a premium. Senior loans are typically made to U.S. and, to a lesser extent, non-U.S. corporations, partnerships and other business entities which operate in various industries and geographical regions.

The senior loan market has seen a significant increase in loans with few or none of the financial maintenance covenants (i.e.,“covenant-lite loans”) that have traditionally protected lenders including more aggressive terms that favor borrowers with respect to restrictions regarding additional debt, payment terms, income requirements and asset dispositions. A substantial amount of the senior loans held by the Fund are expected to be covenant-lite loans, meaning the Fund may be unable to declare an event of default if financial performance deteriorates, renegotiate the terms of the loan based upon the elevated risk levels or take other actions to help mitigate losses.

Corporate Debt Securities

Other Debt Securities

The Fund may invest in unsecured and/or subordinated bank loans, loan participations and unfunded contracts. The Fund may invest in such loans by purchasing assignments on all or a portion of loans or loan participations from third parties. These loans are made by or issued to corporations primarily to finance acquisitions, refinance existing debt, support organic growth, or pay out dividends, and are typically originated by large banks and then syndicated out to institutional investors as well as to other banks. Bank loans typically bear interest at a floating rate although some loans pay a fixed rate.

High Yield Debt

The Fund invests primarily in debt instruments (e.g., bonds, loans and convertible bonds) that are rated below investment grade, or unrated securities deemed by the Advisor to be of comparable quality. Debt securities rated below investment grade are commonly referred to as “high yield” or “junk” debt. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. High yield debt may be issued by companies without long track records of sales and earnings, or by issuers that have questionable credit strength. High yield debt and comparable unrated debt securities: (a) will likely have some quality and protective characteristics that, in the judgment of the rating agency evaluating the instrument, are out weighed by large uncertainties or major risk exposures to adverse conditions; and (b) are predominantly speculative with respect to the issuer’s capacity to pay dividends or interest and repay principal in accordance with the terms of the obligation.

Non-U.S. Debt Securities

Non-U.S. debt securities include debt securities issued or guaranteed by companies organized under the laws of countries other than the United States, debt securities issued or guaranteed by foreign, national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities and debt obligations of supranational governmental entities such as the World Bank or European Union. These debt securities may be U.S. dollar-denominated or non-U.S. dollar-denominated. Non-U.S. debt securities also include U.S. dollar-denominated debt obligations, such as “Yankee Dollar” obligations, of foreign issuers and of supranational government entities. Yankee Dollar obligations are U.S. dollar-denominated obligations issued in the U.S. capital markets by foreign corporations, banks and governments. Non-U.S. debt securities also may be traded on non-U.S. securities exchanges or in over-the-counter capital markets. Under normal market conditions, up to 10% of the net assets (including investment borrowings) of the Fund may be denominated in currencies other than the U.S. dollar. To the extent the Fund invests in such instruments, the value of the assets of the Fund as measured in U.S. dollars will be affected by changes in exchange rates. Generally, the Fund’s currency exchange transactions will be conducted on a spot (i.e., cash) basis at the spot rate prevailing in the currency exchange market. The cost of the Fund’s currency exchange transactions will generally be the difference between the bid and offer spot rate of the currency being purchased or sold. In order to protect against uncertainty in the level of future currency exchange rates, the Fund is authorized to enter into various currency exchange transactions.

Non-Principal Investments

U.S. Government Securities

or sponsored by the U.S. government. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

Convertible Bonds

The Fund may invest in convertible bonds. Convertible bonds combine the investment characteristics of bonds and common stocks. Convertible bonds typically consist of debt securities or preferred securities that may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. They also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Convertible bonds entitle the holder to receive interest paid or accrued on debt, or dividends paid or accrued on preferred securities, until the securities mature or are redeemed, converted or exchanged.

Preferred Securities

The Fund may invest in preferred securities, which generally pay fixed or adjustable-rate dividends or interest to investors and have preference over common stock in the payment of dividends or interest and the liquidation of a company’s assets, which means that a company typically must pay dividends or interest on its preferred securities before paying any dividends on its common stock. Preferred securities are generally junior to all forms of the company’s debt, including both senior and subordinated debt.

Cash Equivalents and Short-Term Investments

Normally, the Fund invests substantially all of its assets to meet its investment objectives. However, the Fund may invest in short-term debt securities, money market funds and other cash equivalents, or it may hold cash. The percentage of the Fund invested in such holdings varies and depends on several factors, including market conditions. For temporary defensive purposes and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities, or it may hold cash. During such periods, the Fund may not be able to achieve its investment objectives. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the Fund's SAI.

Illiquid Securities

The Fund may invest up to 15% of its net assets in securities and other instruments that are, at the time of investment, illiquid (determined using the Securities and Exchange Commission's standard applicable to investment companies, i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For this purpose, illiquid securities may include, but are not limited to certain restricted securities (securities the disposition of which is restricted under the federal securities laws), certain securities that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), that are deemed to be illiquid, and certain repurchase agreements.

Investment Companies and Other Pooled Investment Vehicles

The Fund may invest in securities of investment companies and other pooled investment vehicles, including exchange-traded funds (“ETFs”). ETFs trade on a securities exchange and their shares may, at times, trade at a premium or discount to their net asset value. As a shareholder in a pooled investment vehicle, the Fund bears its ratable share of that vehicle's expenses, and would remain subject to payment of the fund's advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other pooled investment vehicles. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed-end investment companies. Securities of other pooled investment vehicles may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile than securities of unleveraged vehicles.

The Fund’s investment in other investment companies that adhere to a Name Policy with respect to senior loans shall be counted towards the Fund’s investment policy of investing, under normal market conditions, at least 80% of its net assets (including

investment borrowings) in Senior Loans. For purposes of satisfying the Fund’s investment restrictions, such senior loan funds will also be considered below investment grade securities. The Fund may also invest in certain affiliated open-end funds or ETFs that are advised by the Advisor, in which case the Fund shall receive a rebate for any advisory fees borne in connection with the purchase of the shares of such affiliated open-end funds or ETFs.

Disclosure of Portfolio Holdings

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objectives. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

BANK LOANS RISK. The Fund may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of the underlying borrower. Participations by the Fund in a lender's portion of a bank loan typically will result in the Fund having a contractual relationship only with such lender, not with the borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower, which exposes the Fund to the credit risk of the lender. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. There is also the risk that the value of any collateral securing a loan may decline and that the collateral may be insufficient to cover the amount owed on the loan. The secondary market for bank loans may not be highly liquid, and the Fund may have difficulty selling bank loans (other than at a discount) and it may experience settlement delays with respect to bank loan trades (in some cases longer than 7 days.) Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the anti-fraud protections of the federal securities laws and would be forced to rely upon the contractual persons in the loan agreement and states law to enforce its rights to repayment. Many of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. The amount of public information available with respect to bank loans may be less extensive than available for registered or exchange-traded securities. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience relatively greater realized or unrealized losses or delays in enforcing its rights on its holdings of covenant-lite loans than its holdings of loans with the usual covenants.

COUNTERPARTY RISK. The Fund is subject to counterparty risk. If the Fund enters into an investment or transaction that depends on the performance of another party, the Fund becomes subject to the credit risk of that counterparty. The Fund's ability to profit from these types of investments and transactions depends on the willingness and ability of the Fund’s counterparty to perform its obligations. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving a counterparty (including recovery of any collateral posted by it) and may obtain only a limited recovery or may obtain no recovery in such circumstances. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty. Under applicable law or contractual provisions, including if the Fund enters into an investment or transaction with a financial institution and such financial institution (or an affiliate of the financial institution) experiences financial difficulties, then the Fund may in certain situations be prevented or delayed from exercising its rights to terminate the investment or transaction, or to realize on any collateral and may result in the suspension of payment and delivery obligations of the parties under such investment or transactions or in another institution being substituted for that financial institution without the consent of the Fund. Further, the Fund may be subject to “bail-in” risk under applicable law whereby, if required by the financial institution's authority, the financial institution's liabilities could be written down, eliminated or converted into equity or an alternative instrument of ownership. A bail-in of a financial institution may result in a reduction in value of some or all of securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, the Fund may also be similarly impacted.

COVENANT-LITE LOANS RISK. The Fund may invest in covenant-lite loans. The loan agreement, which sets forth the terms of a loan and the obligations of the borrower and lender, contains certain covenants that mandate or prohibit certain borrower actions, including financial covenants that dictate certain minimum and maximum financial performance levels. Covenants that require the borrower to maintain certain financial metrics during the life of the loan (such as maintaining certain levels of cash flow and limiting leverage) are known as “maintenance covenants.” These covenants are included to permit the lender to monitor the performance of the borrower and declare an event of default if breached, allowing the lender to renegotiate the terms of the loan based upon the elevated risk levels or take other actions to help mitigate losses. Covenant-lite loans contain fewer or no maintenance covenants making an investment in these types of loans inherently riskier than an investment in loans containing provisions allowing the lender reprice credit risk associated with the borrower or restructure a problematic loan. Since 2013, the number of covenant-lite loans issued has increased significantly. The Fund’s elevated exposure to such loans during a downturn in the credit cycle could cause the Fund to experience outsized losses.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

issuers. Such issuers are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund. An economic downturn would also generally lead to a higher non-payment rate, and a floating rate debt instrument may lose significant market value before a default occurs. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods which may cause the Fund to be unable to realize the full value of its investment. Lastly, floating rate loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

in interest rates could also cause principal payments on a debt security to be repaid at a slower rate than expected. This risk is particularly prevalent for a callable debt security where an increase in interest rates could cause the issuer of that security to not redeem the security as anticipated on the call date, effectively lengthening the security’s expected maturity, in turn making that security more vulnerable to interest rate risk and reducing its market value. When interest rates fall, the Fund may be required to reinvest the proceeds from the sale, redemption or early prepayment of a debt security at a lower interest rate.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other

instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SENIOR LOAN RISK. Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by the assets of the borrower. The senior loan market has seen a significant increase in loans with limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan credit agreement and general weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions, all of which may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may be unable to declare a default if financial performance deteriorates. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

Senior loans are also subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk that may be heightened because of the limited public information available regarding senior loans and because loan borrowers may be more highly leveraged and tend to be more adversely affected by changes in market or economic conditions. If the Fund holds a senior loan through another financial institution or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. Although senior loans are generally secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by equity interests in the borrower or its subsidiaries, such equity interest may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss. Senior loans made in connection with highly leveraged transactions are subject to greater risks than other senior loans. For example, the risks of default or bankruptcy of the borrower or the risks that other creditors of the borrower may seek to nullify or subordinate the Fund’s claims on any collateral securing the loan are greater in highly leveraged transactions.

Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for senior loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may cause the Fund to be unable to realize the full value of its investment. Lastly, senior loans may not be considered “securities,” and the Fund may not be entitled to rely on the anti-fraud protections of the federal securities laws and could be forced to rely on the contractual provisions in the loan agreement and state law to enforce its right to repayment.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

Non-Principal Risks

CONVERTIBLE SECURITIES RISK. Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer, depending on the terms of the securities) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying equity security or sell it to a third party, which may have an adverse effect on the Fund’s ability to achieve its investment objective. The market values of convertible securities tend to decline as interest rates increase. However, a

convertible security’s market value also tends to reflect the market price of the equity security of the issuing company, particularly when the price of the equity security is greater than the convertible security’s conversion price (i.e., the predetermined price or exchange ratio at which the convertible security can be converted or exchanged for the underlying equity security). Convertible securities are also exposed to the risk that an issuer will be unable to meet its obligation to make dividend or principal payments when due as a result of changing financial or market conditions. Convertible debt securities generally offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of their potential for capital appreciation. Moreover, there can be no assurance that convertible securities will provide current income prior to conversion because the issuers of the convertible securities may default on their obligations. If the convertible security has a conversion or call feature that allows the issuer to redeem the security before the conversion date, the potential for capital appreciation may be diminished. In the event that convertible securities are not optional but mandatory based upon the price of the underlying common stock, the Fund may be subject to additional exposure to loss of income in situations where it would prefer to hold debt.

DEFAULTED SECURITIES RISK. The Fund may invest in defaulted securities. Defaulted securities pose a greater risk that principal will not be repaid than non-defaulted securities. The reorganization or liquidation of an issuer of a defaulted security may result in the Fund losing its entire investment or being required to accept cash or securities with a value less than its original investment. It may also be difficult to obtain complete and accurate information regarding the true financial condition of the issuer of a defaulted security. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

DISTRESSED SECURITIES RISK. The Fund may invest in distressed debt securities. Distressed securities are speculative and involve substantial risks in addition to the risks of investing in high-yield debt securities that are not in default. In some instances, the Fund will not receive interest payments from the distressed securities it holds and may incur additional expenses to protect its investment. These securities may present a substantial risk of default and there is a substantial risk that the principal will not be repaid. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or of interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in exchange for such securities may be subject to restrictions on resale.

the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

FAILURE TO QUALIFY AS A REGULATED INVESTMENT COMPANY RISK. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. In such circumstances, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment. If the Fund fails to qualify as a regulated investment company, distributions to the Fund's shareholders generally would be eligible (i) for treatment as qualified dividend income in the case of individual shareholders and (ii) for the dividends received deduction in the case of corporate shareholders. See "Federal Tax Matters."

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund will trade on non-U.S. exchanges that are closed when the Fund's primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market), resulting in premiums or discounts to the Fund's net asset value that may be greater than those experienced by other ETFs. However, because shares can be created and redeemed in Creation Units at the Fund’s net asset value, it is not expected that large discounts or premiums to the net asset value of the Fund will be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values).

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain companies represented owned by the Fund. In addition, litigation regarding any of the issuers of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Sub-Advisor determines to sell such a holding.

nationalization of non-U.S. holdings, the imposition of sanctions by foreign governments, the possible establishment of capital controls, exchange controls or freezes on the convertibility of currency or the adoption of other governmental restrictions might adversely affect an investment in non-U.S. securities. Additionally, non-U.S. issuers may be subject to less stringent regulation, and to different accounting, auditing and recordkeeping requirements. The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other regional developments particular to a given country or region.

PREFERRED SECURITIES RISK. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Preferred securities often include provisions that permit the issuer, at its discretion, to defer distributions for a stated period without any adverse consequences to the issuer. If the Fund owns a preferred security that is deferring its distributions, the Fund may be required to report income for federal income tax purposes although it has not yet received such income in cash. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board of director. Generally, once the issuer pays all the arrearages, the preferred security holders no longer have voting rights. In certain circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws or a change in regulatory trademark. As with redemption provisions of debt securities, a special redemption by the issuer may negatively impact the return of the preferred security held by the Fund. Preferred securities may also be substantially less liquid than other securities, including common stock.

WARRANTS RISK. The prices of warrants, which entitle the holder to purchase equity securities at specific prices for a certain period of time, do not necessarily move parallel to the prices of the underlying securities and likely fluctuate more than the prices of the underlying securities. Warrants have no voting rights, receive no dividends, and have no rights with respect to the assets of the issuer.

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the "Investment Management Agreement"), First Trust manages the investment of the Fund's assets. First Trust is paid an annual management fee equal to 0.85% of the Fund’s average daily net assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

A discussion regarding the Board’s approval of the continuation of the Investment Management Agreement is available in the Fund’s Annual Report to Shareholders for the fiscal year ended October 31, 2020.

How to Buy and Sell Shares

For purposes of the 1940 Act, the Fund is treated as a registered investment company, and, absent an available exemption or exemptive relief, the acquisition of shares by other registered investment companies and companies relying on Section 3(c)(1) or 3(c)(7) of the 1940 Act is subject to the restrictions of Section 12(d)(1) of the 1940 Act. The Trust, on behalf of the Fund, has received an exemptive order from the Securities and Exchange Commission that permits certain registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that any such investment companies enter into an agreement with the Fund regarding the terms of any investment.

Book Entry

of shares, you are not entitled to receive physical delivery of share certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book-entry or “street name” form.

Share Trading Prices

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate, however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Investments in Certain Non-U.S. Corporations

If the Fund holds an equity interest in any passive foreign investment companies, which are generally certain non-U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such passive foreign investment company shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from passive foreign investment companies and its proceeds from dispositions of passive foreign investment company stock during that year, and such income would nevertheless be subject to the distribution

requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by passive foreign investment companies are not treated as qualified dividend income.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value, in accordance with valuation procedures adopted by the Board and in accordance with the 1940 Act. Portfolio securities listed on any exchange other than Nasdaq and the London Stock Exchange Alternative Investment Market (“AIM”) are valued at the last sale price on the business day as of which such value is being determined. Securities listed on Nasdaq or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of Senior Loans than for other types of securities. Typically, Senior Loans are fair valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board or its delegate, the Advisor’s Pricing Committee, at fair value. The use of fair value pricing by the Fund is governed by valuation procedures adopted by the Board and in accordance with the provisions of the 1940 Act. These securities generally include, but are not limited to, certain restricted securities (securities which may not be publicly sold without registration under the Securities Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s net asset value or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from the current market valuations. See the Fund’s SAI for details.

Principal Investment Strategies

Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of U.S. and non-U.S. convertible securities (described below). In general, convertible securities combine the investment characteristics of bonds and common stocks and typically consist of debt securities or preferred securities that may be converted or exchanged within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security (such equity securities referred to as “underlying securities”) of the same or a different issuer (and/or the cash equivalent thereof). A convertible security is designed to provide current income and also the potential for capital appreciation through the conversion feature, which enables the holder to benefit from increases (if any) in the market price of the underlying equity security. Accordingly, these equity-linked instruments offer the potential for equity market participation along with, in light of their bond-like characteristics, potential mitigated downside risk (which is generally the risk that a security may suffer a decline in value) in periods of equity market declines.

The Fund may invest in the following convertible securities (collectively, the “Convertible Securities”):

•

Convertible and exchangeable notes, bonds and debentures;

•

Convertible preferred securities;

•

Mandatory convertible securities (Conversion is not optional for these convertible securities, which automatically convert on maturity.);

•

Contingent convertible securities (“CoCos”) (These convertible securities may provide for conversion under certain circumstances, including, for example: if a company fails to meet the minimum amount of capital described in the security; if the company’s regulator makes a determination that the security should convert; or if the company receives specified levels of extraordinary public support. Additionally, CoCos may contain features that limit an investor’s ability to convert the convertible security into its underlying security unless certain conditions are met, including, for example, when the sale price of the underlying security exceeds the conversion price by a specified percentage for a certain specified period of time.);

•

Synthetic convertible securities (These convertible securities (a) consist of two or more distinct securities whose economic characteristics, when taken together, resemble those of traditional convertible securities (i.e., an income-producing security and the right to acquire an equity security (through, for example, an option or a warrant)); or (b) are exchangeable or equity-linked securities issued by a broker-dealer, investment bank or other financial institution with proceeds going directly to the broker-dealer, investment bank or other financial institution, as applicable, that have economic characteristics similar to those of traditional convertible securities.);

•

Corporate bonds and preferred securities with attached warrants; and

•

Convertible securities that are eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) (such as, for example, convertible securities that are issued in private placements).

In selecting securities for the Fund, SSI Investment Management LLC, the Fund’s sub-advisor (the “Sub-Advisor”), utilizes both quantitative and fundamental analysis to construct a portfolio of Convertible Securities intended to provide an attractive level of returns typically associated with investments in equity securities, but with a degree of downside protection that is provided through bond-like characteristics. Through its investment process, the Sub-Advisor attempts to identify attractive Convertible Securities based on its positive view of the underlying security or its view of the company’s potential for credit improvement. The Sub-Advisor screens the universe for Convertible Securities that present the most attractive reward per unit of risk. Once attractive Convertible Securities have been identified, the Sub-Advisor generally uses fundamental equity and credit analysis to determine which of the attractive Convertible Securities it believes have a sound underlying security with potential for increase in value. In conjunction with its analysis, the Sub-Advisor reviews the overall economic situation. In this regard, the Fund is actively managed, whereby, the Sub-Advisor assesses the position of the economic cycle and the performance outlook for certain economic sectors. In making decisions to purchase or sell Convertible Securities, the Sub-Advisor will, at times, over- or underweight different economic sectors, market capitalizations, and credit quality exposures relative to the available universe of Convertible Securities. The Sub-Advisor may also adjust the sensitivity of the portfolio to movements in the equity market and to interest rates based on the macroeconomic outlook. The Fund may manage the market exposure defensively during periods of market distress.

The Fund may invest in Convertible Securities of any credit quality, including securities that are rated below investment grade or unrated, and with effective or final maturities of any length. Below investment grade securities are commonly referred to as “junk” or “high yield” securities and are considered speculative with respect to the issuer’s capacity to pay interest and repay principal. The Fund’s investment advisor expects that, under normal market conditions, generally, for a Convertible Security to be considered as an eligible investment, after taking into account such an investment, at least 75% of the Fund’s net assets that are invested in Convertible Securities will be comprised of Convertible Securities that will have, at the time of original issuance, $200 million or more in par amount outstanding.

The Fund will limit its investments in synthetic convertible securities to 10% of its net assets (calculated at the time of investment). The Fund’s investments in options will be limited to options that represent a component of a synthetic convertible security.

The Fund may invest, without limit, in securities that have not been registered under the Securities Act and continue to be subject to restrictions on resale, securities held by control persons of the issuer and securities that are subject to contractual restrictions on their resale (collectively, “restricted securities”). Restricted securities include, without limitation, securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act (“Rule 144A”) and other securities issued in private placements. Under normal market conditions, the Fund will limit its investments in Convertible Securities that are Rule 144A securities to securities with $100 million or more in principal amount outstanding as of the time of their original issuance.

In addition to investing in Convertible Securities, the Fund also may invest in the following securities and instruments. The Fund may invest up to 20% of its net assets in exchange-traded notes (“ETNs”), which are a type of senior, unsecured, unsubordinated debt security issued by financial institutions that combines both aspects of bonds and exchange-traded funds (“ETFs”). The Fund may invest up to 20% of its net assets in equity securities listed on U.S. or non-U.S. securities exchanges, including, but not limited to, American Depositary Receipts, Global Depositary Receipts, equity securities issued by business development companies (“BDCs”), and equity securities held upon conversion of Convertible Securities into their corresponding underlying securities. In addition, the Fund may invest in exchange-listed futures contracts on equity indexes, exchange-listed and over-the-counter (“OTC”) index credit default swaps, and forward foreign currency exchange contracts; however, the Fund will limit the aggregate notional value of its positions in these instruments (calculated at the time of investment) to 10% of the value of its net assets. As of January 31, 2021, the Fund had significant investments in consumer discretionary companies and information technology companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

To the extent permitted under applicable law, percentage limitations described in this prospectus are generally as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of market fluctuations affecting the Fund’s portfolio securities.

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

CONSUMER DISCRETIONARY COMPANIES RISK. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace.

CONVERTIBLE SECURITIES RISK. A convertible security has characteristics of both equity and debt securities and, as a result, is exposed to risks that are typically associated with both types of securities. The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security tends to perform more like a stock when the underlying stock price is high relative to the conversion price and more like a debt security when the underlying stock price is low relative to the conversion price.

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies produce and provide hardware, software and information technology systems and services. These companies may be adversely affected by rapidly changing technologies, short product life cycles, fierce competition, aggressive pricing and reduced profit margins, the loss of patent, copyright and trademark protections, cyclical market patterns, evolving industry standards and frequent new product introductions. In addition, information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies also heavily rely on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.

Additional Information on the Fund's Investment Objective and Strategies

The Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”) whereby the Fund, under normal market conditions, invests at least 80% of its net assets (including investment borrowings) in Convertible Securities. The Name Policy may be changed by the Board without shareholder approval upon 60 days’ prior written notice. While it is not expected that the Fund will invest in the securities of other investment companies, any such investments would be subject to limitations imposed by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

Convertible Securities

Convertible securities are generally bonds, debentures, notes, preferred securities or other securities or investments that may be converted or exchanged into equity securities (and/or the cash equivalent thereof), which may be at a stated exchange ratio or predetermined price (the “conversion price”). A convertible security is designed to provide current income and also the potential for capital appreciation through the conversion feature, which enables the holder to benefit from increases (if any) in the market price of the underlying equity security. Accordingly, these equity-linked instruments offer the potential for equity market participation along with, in light of their bond-like characteristics, potential mitigated downside risk (which is generally the risk that a security may suffer a decline in value) in periods of equity market declines.

A convertible security generally entitles the holder to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt obligations and are designed to provide for a stable stream of income with generally higher yields than common stocks. However, there can be no assurance of current income because the issuers of the convertible securities may default on their obligations.

A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying equity security or sell it to a third party, which may have an adverse effect on the Fund’s ability to achieve its investment objective.

Convertible securities have valuation characteristics similar to both debt and equity securities. Convertible securities generally offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of the potential for capital appreciation. The value of convertible securities is influenced by both the yield of non-convertible securities of comparable issuers and by the value of the underlying equity security. The value of a convertible security viewed without regard to its conversion feature (i.e., strictly on the basis of its yield) is sometimes referred to as its “investment value.” The investment value of the convertible security typically will fluctuate based on the credit quality of the issuer and will fluctuate inversely with changes in prevailing interest rates. However, at the same time, the value of a convertible security will be influenced by its “conversion value,” which is the market value of the underlying equity security that would be obtained if the convertible security were converted. Conversion value fluctuates directly with the price of the underlying equity security, and will therefore be subject to risks relating to the activities of the issuer of the underlying equity security and general market

and economic conditions. Depending upon the relationship of the conversion price to the market value of the underlying security, a convertible security may trade more like an equity security than a debt instrument.

If, because of a low price of the underlying equity security, the conversion value is substantially below the investment value of the convertible security, the price of the convertible security is governed principally by its investment value. Generally, if the conversion value of a convertible security increases to a point that approximates or exceeds its investment value, the value of the security will be principally influenced by its conversion value. A convertible security will sell at a premium over its conversion value to the extent investors place value on the right to acquire the underlying equity security while holding an income-producing security.

Debt and preferred securities with warrants attached to purchase equity securities have many characteristics of convertible securities and their prices may, to some degree, reflect the performance of the underlying equity security. A warrant is a right to purchase an equity security at a specific price (usually at a premium above the market value of the underlying equity security at the time of issuance) during a specified period of time.

Contingent Convertible Securities. Contingent convertible securities (which generally provide for conversion under certain circumstances) are distinguished as a subset of convertible securities. Similar to mandatory convertible securities (and unlike traditional convertible securities), some contingent convertible securities provide for mandatory conversion under certain circumstances. The mandatory conversion might be automatically triggered, for instance, if a company fails to meet the minimum amount of capital described in the security, the company’s regulator makes a determination that the security should convert or the company receives specified levels of extraordinary public support. Since the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero, and conversion would deepen the subordination of the investor, hence worsening standing in a bankruptcy. Further, some contingent convertible securities have a set stock conversion rate that would cause a reduction in value of the security if the price of the stock is below the conversion price on the conversion date. In addition, various contingent convertible securities may contain features that limit an investor’s ability to convert the security unless certain conditions are met.

Exchangeable Debt Securities. Exchangeable debt securities are convertible debt securities in which the underlying equity security is issued by an entity that is different from the issuer of the convertible securities, often a subsidiary of the issuer. The valuation of an exchangeable debt security is similar to that of a convertible debt security, with the conversion value influenced by the issuer of the underlying equity security.

Mandatory Convertible Securities. Mandatory convertible securities are distinguished as a subset of convertible securities because the conversion is not optional and the conversion price at maturity (or redemption) is based solely upon the market price of the underlying equity security, which may be significantly less than par or the price (above or below par) paid. Mandatory convertible securities automatically convert to equity securities at maturity. For these reasons, the risks associated with investing in mandatory convertible securities most closely resemble the risks inherent in equity securities. Mandatory convertible securities customarily pay a higher coupon yield to compensate for the potential risk of additional price volatility and loss upon redemption. Since the correlation of common stock risk increases as the security approaches its redemption date, there can be no assurance that the higher coupon will compensate for the potential loss.

Synthetic Convertible Securities. Some synthetic convertible securities consist of two or more distinct securities whose economic characteristics, when taken together, resemble those of traditional convertible securities (i.e., an income producing component and the convertible component). For example, the income producing component may be achieved by purchasing non-convertible securities such as bonds, preferred securities or money market instruments and the convertible component may be achieved through warrants or options to buy common stock at a certain exercise price, or options on a stock index. Other synthetic convertible securities include exchangeable or equity-linked securities issued by a broker-dealer, investment bank or other financial institution with proceeds going directly to the broker-dealer, investment bank or other financial institution, as applicable, that have economic characteristics similar to those of traditional convertible securities.

Synthetic convertibles are typically offered by financial institutions in private placement transactions and are typically sold back to the offering institution. Upon conversion, the holder generally receives from the offering institution shares and/or cash of the then-current value of the underlying securities.

Synthetic convertible securities may differ from traditional convertible securities in several respects. The value of a synthetic convertible is the sum of the values of its income producing component and its convertible component. Thus, the values of a synthetic convertible and a traditional convertible security will respond differently to market fluctuations. Purchasing a synthetic convertible security may provide greater flexibility than purchasing a traditional convertible security, including the

ability to combine components representing distinct issuers or to combine a fixed income security with a call option on a stock index. In addition, synthetic convertible securities may alter the characteristics common to traditional convertible securities such as by offering enhanced yields in exchange for reduced capital appreciation or less downside protection. The component parts of a synthetic convertible security may be purchased simultaneously or separately.

The holder of a synthetic convertible faces the risk that the price of the stock, or the level of the market index underlying the convertible component, will decline. In addition, in purchasing a synthetic convertible security, a Fund may have counterparty risk with respect to the financial institution that offers the instrument or with respect to the institution that issued the income producing component of the convertible security when such an institution is not the financial institution creating the synthetic convertible security. Synthetic convertible securities are also subject to additional liquidity risk and to the risks associated with derivatives.

Synthetic convertible securities include convertible structured notes, which are income producing debentures linked to equity and are typically issued by investment banks. Convertible structured notes have the attributes of a convertible security. However, the credit risk that the Fund assumes on purchasing such a security pertains to the investment bank that issues the convertible note, rather than the issuer of the underlying equity security into which the note is convertible.

Debt Securities

Debt securities include obligations typically issued by corporations to borrow money from investors, such as corporate bonds, debentures and notes. These securities may be either secured or unsecured. Holders of debt securities, as creditors, have a prior legal claim over common and preferred shareholders as to both income and assets of the issuer for the principal and interest due them and may have a prior claim over other creditors if liens or mortgages are involved. Interest on debt securities is typically paid semi-annually and is fully taxable to the holder of the securities. The investment return of debt securities reflects interest on the security and changes in the market value of the security. The market value of a fixed rate debt security generally may be expected to rise and fall inversely with changes in interest rates and also may be affected by the credit rating of the issuer, the issuer’s performance and perceptions of the issuer in the marketplace. Debt securities issued by corporations usually have a higher yield than government or agency bonds due to the presence of credit risk. Certain of the debt securities in which the Fund may invest may be rated below investment grade (commonly referred to as “junk” or “high yield” securities).

Exchange-Traded Notes. ETNs are a type of senior, unsecured, unsubordinated debt security issued by financial institutions that combines both aspects of bonds and ETFs. An ETN’s returns are based on the performance of a market index minus fees and expenses. Similar to ETFs, ETNs are listed on an exchange and traded in the secondary market. However, unlike an ETF, an ETN can be held until the ETN’s maturity, at which time the issuer is obligated to pay a return linked to the performance of the market index to which the ETN is linked minus certain fees. Unlike regular bonds, ETNs do not make periodic interest payments and principal is not protected. When the Fund invests in ETNs, it will bear its proportionate share of any fees and expenses borne by the ETN. The Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market. In addition, although an ETN may be listed on an exchange, the issuer may not be required to maintain the listing and there can be no assurance that a secondary market will exist for an ETN.

High Yield Securities. The Fund may invest in securities of any credit quality, including securities that are rated below investment grade. Below investment grade securities are rated below “BBB-” by Standard & Poor’s Ratings Group, a division of The McGraw-Hill Companies (“S&P”), or Fitch Ratings, Inc. (“Fitch”), below “Baa3” by Moody’s Investors Service, Inc. (“Moody’s”) or comparably rated by another nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Sub-Advisor to be of comparable credit quality at the time of purchase. Below investment grade securities are commonly referred to as “junk” or “high yield” securities and are considered speculative with respect to the issuer’s capacity to pay interest and repay principal.

Equity Securities

The Fund may hold equity securities in its portfolio through direct investments in equity securities or upon conversion of a Convertible Security into its corresponding underlying security. Equity securities include common and preferred stocks, depositary receipts, and equity interests in BDCs. An investment in the equity securities of a company represents a proportionate ownership interest in that company. Therefore, the Fund participates in the financial success or failure of any company in which it has an equity interest.

Business Development Companies. BDCs are a type of closed-end fund regulated under the 1940 Act that typically invest in and lend to small and medium-sized private and certain public companies that may not have access to public equity markets for capital raising. BDCs invest in such diverse industries as healthcare, chemical and manufacturing, technology and service

companies. BDCs are unique in that at least 70% of their investments must be made in private and certain public U.S. businesses, and BDCs are required to make available significant managerial assistance to their portfolio companies. Unlike corporations, BDCs are not taxed on income distributed to their shareholders provided they comply with the applicable requirements of the Internal Revenue Code of 1986, as amended. BDCs, which are required to distribute substantially all of their income to investors in order to not be subject to entity level taxation, often offer a yield advantage over other types of securities. The Fund will indirectly bear its proportionate share of any management and other expenses, and of any performance based or incentive fees, charged by the BDCs in which it invests, in addition to the expenses paid by the Fund. The Fund is permitted to invest in BDCs in excess of the limits imposed under the 1940 Act pursuant to an exemptive order obtained by the Trust and the Advisor.

Common Stock. Traditional convertible securities are typically converted into common stocks. Common stocks represent residual ownership interest in issuers and holders of common stocks are entitled to the income and increase in the value of the assets and business of the issuers after all debt obligations and obligations to preferred stockholders are satisfied. Common stocks generally have voting rights. Common stocks fluctuate in price in response to many factors including historical and prospective earnings of the issuer, the value of its assets, general economic conditions, interest rates, investor perceptions and market liquidity. The value of common stocks purchased by the Fund could decline if the financial condition of the companies the Fund invests in declines or if overall market and economic conditions deteriorate. Their value also may decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

Preferred Securities. Preferred securities represent an equity ownership interest in the issuer, but generally entitle the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from liquidation of the company. Some preferred securities also entitle their holders to receive additional liquidation proceeds on the same basis as holders of a company’s common stock. Some preferred securities offer a fixed rate of return with no maturity date. Because those preferred securities never mature, they act like long-term bonds, can be more volatile than other types of preferred securities and may have heightened sensitivity to changes in interest rates. Other preferred securities have a variable dividend, generally determined on a quarterly or other periodic basis, either according to a formula based upon a specified premium or discount to the yield on particular U.S. Treasury securities or based on an auction process, involving bids submitted by holders and prospective purchasers of such stocks. Because preferred securities represent an equity ownership interest in a company, their value usually will react more strongly than bonds and other debt instruments to actual or perceived changes in the company’s financial condition or prospects or to fluctuations in the equity markets. Holders of preferred securities generally have no voting rights or their voting rights are limited to certain extraordinary transactions or events.

Non-U.S. Investments

Non-U.S. investments include securities issued or guaranteed by companies organized under the laws of countries other than the United States, including companies domiciled in emerging markets. Non-U.S. investments may be traded on foreign securities exchanges or in over-the-counter capital markets. Many non-U.S. companies issue both foreign currency and U.S. dollar-denominated securities. The Fund may also invest in ADRs and GDRs, or other securities representing underlying securities of non-U.S. issuers.

ADRs are typically issued by a financial institution (a depositary) and evidence ownership interests in a security or a pool of securities issued by a non-U.S. company and deposited with the depositary. Generally, ADRs in registered form are dollar-denominated securities designed for use in the U.S. securities markets. GDRs are receipts issued outside the United States, typically by non-United States banks and trust companies, that evidence ownership of either non-U.S. or domestic securities. Generally, GDRs are designed for use outside the United States. ADRs and GDRs may be issued as sponsored or unsponsored programs. In sponsored programs, an issuer has made arrangements to have its securities trade in the form of ADRs or GDRs. Unsponsored ADR and GDR programs are organized independently and without the cooperation of the issuer of the underlying securities. The Fund will only invest in sponsored ADRs and GDRs.

In connection with its non-U.S. investments, to protect the value of its portfolio against uncertainty in the level of future currency exchange rates, the Fund may enter into foreign currency transactions on a spot (i.e., cash) basis or it may enter into forward foreign currency exchange contracts (described below).

Derivative Instruments

The Fund may invest in exchange-listed futures contracts on equity indexes, exchange-listed and OTC index credit default swaps, and forward foreign currency exchange contracts; however, the Fund will limit the aggregate notional value of its positions in these instruments (calculated at the time of investment) to 10% of the value of its net assets. The Fund will enter into the foregoing transactions to seek to manage the risks of the Fund’s portfolio securities or for investment or other purposes to the extent the Sub-Advisor determines that their use would be consistent with the investment objective and policies of the Fund, as well as applicable regulatory requirements. Generally, derivatives are financial contracts whose values depend upon, or are derived from, the value of an underlying asset, reference rate or index, and may relate to, among others, individual debt instruments, interest rates, currencies or currency exchange rates, commodities and related indexes. Certain of the Fund’s derivative transactions may provide investment leverage to the Fund’s portfolio.

The Fund’s investments in derivative instruments will be consistent with the Fund’s investment objective and the 1940 Act and will not be used to seek to achieve a multiple or inverse multiple of an index. The Fund will only enter into transactions in OTC index credit default swaps and forward foreign currency exchange contracts with counterparties that the Advisor and/or the Sub-Advisor reasonably believes are capable of performing under the applicable agreement.

Futures Contracts. The Fund may invest in exchange-listed futures contracts that provide long or short exposure to an underlying equity index, either for hedging or investment purposes. A futures contract may generally be described as an agreement between two parties to buy and sell particular financial instruments for an agreed price during a designated month or to deliver the final cash settlement price in the case of a contract relating to an index or otherwise not calling for physical delivery at the end of trading in the contract. The price at which the contract trades (the “contract price”) is determined by relative buying and selling interest on a regulated exchange. The Fund’s use of futures contracts will in all cases be consistent with applicable regulatory requirements, including the rules and regulations of the Commodity Futures Trading Commission.

Transaction costs are incurred when a futures contract is bought or sold and margin deposits must be maintained. Margin is the amount of funds equal to a specified percentage of the current market value of the contract that must be deposited by the Fund with its custodian in the name of the futures commission merchant in order to initiate futures trading and to maintain the Fund’s open positions in futures contracts. A margin deposit is intended to ensure the Fund’s performance of the futures contract. The margin required for a particular futures contract is set by the exchange on which the futures contract is traded and may be significantly modified from time to time by the exchange during the term of the futures contract.

Index Credit Default Swap Agreements. The Fund may invest in exchange-listed and OTC index credit default swap agreements. A swap is a financial instrument that typically involves the exchange of cash flows between two parties on specified dates, where the cash flows are based on agreed-upon prices, rates, indexes, etc. The Fund may be either the buyer or seller in an index credit default swap transaction. The buyer in a credit default contract is obligated to pay the seller a periodic stream of payments over the term of the contract, provided, that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or “par value,” of the reference obligation. Credit default swap transactions are either “physical delivery” settled or “cash” settled. Physical delivery entails the actual delivery of the reference asset to the seller in exchange for the payment of the full par value of the reference asset. Cash settled entails a net cash payment from the seller to the buyer based on the difference of the par value of the reference asset and the current value of the reference asset that may have, through default, lost some, most or all of its value. If no event of default occurs, the buyer will have made a series of periodic payments and recover nothing of monetary value. However, if an event of default occurs, the buyer will receive the full notional value of the reference obligation either through a cash payment in exchange for the asset or a cash payment in addition to owning the reference assets. The seller receives a fixed rate of income throughout the term of the contract, which typically is between six months and five years, provided, that there is no event of default. If an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation.

An index credit default swap is a swap on an index of credit default swaps. Index credit default swaps allow an investor to manage credit risk or to take a position on a basket of credit default swaps (or other instruments) in a more efficient manner than transacting in single name credit default swaps. If a credit event occurs in one of the underlying companies, the protection is paid out via the delivery of the defaulted bond by the buyer of protection in return for payment of the notional value of the defaulted bond by the seller of protection or it may be settled through a cash settlement between the two parties. The underlying company is then removed from the index.

Forward Foreign Currency Exchange Contracts. To protect the value of its portfolio against uncertainty in the level of future currency exchange rates, as noted above, the Fund may enter into foreign currency transactions on a spot (i.e., cash) basis or it may enter into forward foreign currency exchange contracts. A forward foreign currency exchange contract is an obligation

to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract, at a price set on the date of the contract. The Fund expects to invest in forward foreign currency exchange contracts for hedging or currency risk management purposes and not in order to speculate on currency exchange rate movements, and the amount the Fund may invest in such transactions is limited to the extent of its non-U.S. investments. The Fund will only enter into forward foreign currency exchange contracts with parties which it believes to be creditworthy.

Restricted Securities/Rule 144A Securities

Restricted securities include, without limitation, securities eligible for purchase and sale pursuant to Rule 144A and other securities issued in private placements. A restriction on public sale of restricted securities may make it more difficult to value the securities, limit the Fund’s ability to dispose of them and lower the amount the Fund could realize upon their sale. Rule 144A provides a non-exclusive safe harbor exemption from the registration requirements of the Securities Act for the resale of certain securities to certain qualified institutional buyers, such as the Fund. Any resale of these securities must generally be effected through a sale that is registered under the Securities Act or otherwise exempted or excepted from such registration requirements. To the extent privately placed securities held by the Fund qualify under Rule 144A and an institutional market develops for those securities, the Fund likely will be able to dispose of the securities without registering them under the Securities Act. To the extent that institutional buyers become, for a time, uninterested in purchasing these securities, investing in Rule 144A securities could increase the level of the Fund’s illiquidity. The restricted securities held by the Fund that are also Convertible Securities will be treated as such for purposes of the Fund’s policy to invest, under normal market conditions, at least 80% of its net assets in Convertible Securities. In addition, restricted securities determined by the Sub-Advisor to be illiquid are subject to the limitation onthe amount of illiquid securities in which the Fund may invest.

Non-Principal Investments

Cash Equivalents and Short-Term Investments

Under normal market conditions, the Fund may invest up to 20% of its net assets in short-term debt securities and other short-term debt instruments (described below), as well as cash equivalents, or it may hold cash. The percentage of the Fund’s net assets invested in such holdings will vary and depend on several factors, including market conditions. For purposes of the foregoing investment policy, short-term debt securities shall be securities from issuers having a long-term debt rating of at least “A” from S&P, Moody’s or Fitch and shall have a maturity of one year or less. The Fund may invest in the following short-term debt instruments: (i) fixed rate and floating rate U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities; (ii) certificates of deposit issued against funds deposited in a bank or savings and loan association; (iii) bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions; (iv) repurchase agreements, which involve purchases of debt securities and shall only be entered into with financial institutions and dealers believed by the Advisor and/or the Sub-Advisor to present minimal credit risks; (v) bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest; (vi) commercial paper, which are short-term unsecured promissory notes and shall be rated “A-1” or higher by S&P, “Prime-1” or higher by Moody’s or “F1” or higher by Fitch; and (vii) corporate debt obligations.

For temporary defensive purposes and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities or it may hold cash. During such periods, the Fund may not be able to achieve its investment objective. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the SAI.

Risks of Investing in the Fund

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CASH TRANSACTIONS RISK. The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A Fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

CONSUMER DISCRETIONARY COMPANIES RISK. The Fund invests significantly in consumer discretionary companies. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Consumer discretionary companies may also be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace. Consumer discretionary companies have historically been characterized as relatively cyclical and therefore more volatile in times of change.

the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying equity security or sell it to a third party, which may have an adverse effect on the Fund’s ability to achieve its investment objective. The market values of convertible securities tend to decline as interest rates increase. However, a convertible security’s market value also tends to reflect the market price of the equity security of the issuing company, particularly when the price of the equity security is greater than the convertible security’s conversion price (i.e., the predetermined price or exchange ratio at which the convertible security can be converted or exchanged for the underlying equity security). Convertible securities are also exposed to the risk that an issuer will be unable to meet its obligation to make dividend or principal payments when due as a result of changing financial or market conditions. Convertible debt securities generally offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of their potential for capital appreciation. Moreover, there can be no assurance that convertible securities will provide current income prior to conversion because the issuers of the convertible securities may default on their obligations. If the convertible security has a conversion or call feature that allows the issuer to redeem the security before the conversion date, the potential for capital appreciation may be diminished. In the event that convertible securities are not optional but mandatory based upon the price of the underlying common stock, the Fund may be subject to additional exposure to loss of income in situations where it would prefer to hold debt.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments. Debt securities are subject to varying degrees of credit risk which are often reflected in credit ratings. The credit rating of a debt security may be lowered if the issuer or other obligated party suffers adverse changes to its financial condition. These adverse changes may lead to greater volatility in the price of the debt security and affect the security’s liquidity. High yield and comparable unrated debt securities, while generally offering higher yields than investment grade debt with similar maturities, involve greater risks, including the possibility of dividend or interest deferral, default or bankruptcy, and are regarded as predominantly speculative with respect to the issuer’s capacity to pay dividends or interest and repay principal. To the extent that a Fund holds debt securities that are secured or guaranteed by financial institutions, changes in credit quality of such financial institutions could cause values of the debt security to deviate.

on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

INFORMATION TECHNOLOGY COMPANIES RISK. The Fund invests significantly in information technology companies. Information technology companies produce and provide hardware, software and information technology systems and services. Information technology companies are generally subject to the following risks: rapidly changing technologies and existing produce obsolescence; short product life cycles; fierce competition; aggressive pricing and reduced profit margins; the loss of patent, copyright and trademark protections; cyclical market patterns; evolving industry standards; and frequent new product introductions and new market entrants. Information technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, particularly those involved with the internet, have experienced extreme

price and volume fluctuations that are often unrelated to their operating performance. In addition, information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies also face competition for services of qualified personnel and heavily rely on patents and intellectual property rights and the ability to enforce such rights to maintain a competitive advantage.

has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

RESTRICTED SECURITIES RISK. The Fund may invest in restricted securities. Restricted securities are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Restricted securities include private placement securities that have not been registered under the applicable securities laws, such as Rule 144A securities, and securities of U.S. and non-U.S. issuers that are issued pursuant

to Regulation S. Private placements are generally subject to strict restrictions on resale. Restricted securities may be illiquid as they generally are not listed on an exchange and may have no active trading market. The Fund may be unable to sell a restricted security on short notice or may be able to sell them only at a price below current value. It may be more difficult to determine a market value for a restricted security. Also, the Fund may get limited information about the issuer of a restricted security, so it may be less able to predict a loss. In addition, if Fund management receives material non-public information about the issuer, the Fund may as a result be unable to sell the securities. Certain restricted securities may involve a high degree of business and financial risk and may result in substantial losses.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

Non-Principal Risks

government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Issuers in Asia may not be subject to the same accounting, auditing and financial reporting standards as U.S. companies and if their securities are not listed on a U.S. exchange, they may not be subject to the same corporate governance standards as U.S. issuers. In addition, satisfactory custodial services for investment securities may not be available in some Asia countries, which may result in the Fund incurring additional costs and delays in providing transportation and custody services for such securities outside such countries. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund.

BDC RISK. A BDC may invest in the equity and fixed income securities of smaller and developing companies as well as companies that are experiencing financial crises. Investments in these types of companies present a greater risk of loss due to the companies’ youth and limited track records. They are also generally more susceptible to competition and economic and market changes due to limited products and market shares. In addition, the securities of smaller and developing companies and companies experiencing financial crises typically have limited liquidity. These companies may also have limited capital resources, meaning that they present a greater risk of default on fixed income securities issued and of non-payment of dividends on any preferred and common stock issued. A BDC may use leverage (e.g., borrowing and the issuance of fixed income and preferred securities) to finance its own operations and may suffer significant losses if market fluctuations cause the BDC’s net asset value to decline or if related interest charges exceed investment income. The Fund has no control over the investments made by BDCs, and BDCs are subject to additional risks such as the fact that their shares may trade at a market price above or below their net asset value and that an active market may not develop for their shares.

CONTINGENT CONVERTIBLE SECURITIES RISK. CoCos are hybrid securities most commonly issued by banking institutions that present risks similar to debt securities and convertible securities. CoCos are distinct in that they are intended to either convert into equity or have their principal written down upon the occurrence of certain “triggers.” When an issuer’s capital ratio falls below a specified trigger level, or in a regulator’s discretion depending on the regulator’s judgment about the issuer’s solvency prospects, a CoCo may be written down, written off or converted into an equity security. Due to the contingent write-down, write-off and conversion feature, CoCos may have substantially greater risk than other securities in times of financial stress. If the trigger level is breached, the issuer's decision to write down, write off or convert a CoCo may be outside its control, and the Fund may suffer a complete loss on an investment in CoCos with no chance of recovery even if the issuer remains in existence. CoCos are usually issued in the form of subordinated debt instruments to provide the appropriate regulatory capital treatment. If an issuer liquidates, dissolves or winds-up before a conversion to equity has occurred, the rights and claims of the holders of the CoCos (such as the Fund) against the issuer generally rank junior to the claims of holders of unsubordinated obligations of the issuer. In addition, if the CoCos are converted into the issuer's underlying equity securities after a conversion event (i.e., a “trigger”), each holder will be further subordinated. CoCos also may have no stated maturity and have fully discretionary coupons. This means coupon payments can be canceled at the issuer’s discretion or at the request of the relevant regulatory authority in order to help the bank absorb losses, without causing a default. In general, the value of CoCos is unpredictable and is influenced by many factors including, without limitation: the creditworthiness of the issuer and/or fluctuations in such issuer's applicable capital ratios; supply and demand for CoCos; general market conditions and available liquidity; and economic, financial and political events that affect the issuer, its particular market or the financial markets in general.

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause a Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

is not invested, may adversely affect security values and thus the Fund’s holdings. A significant number of countries in Europe are member states in the EU, and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU. After years of negotiations between the United Kingdom and the EU, a withdrawal agreement was reached whereby the United Kingdom formally left the EU. As the second largest economy among EU members, the implications of the United Kingdom’s withdrawal are difficult to gauge and cannot be fully known. Trade between the United Kingdom and the EU is highly integrated through supply chains and trade in services, as well as through multinational companies. The United Kingdom’s departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating political instability in the region).

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests.Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

LATIN AMERICA RISK. The Fund may invest in the securities of Latin American issuers. The economies of Latin American countries have in the past experienced considerable difficulties, including high inflation rates, high interest rates, high unemployment, government overspending and political instability. International economic conditions, particularly those in the United States, Europe and Asia, as well as world prices for oil and other commodities may also influence the development of Latin American economies. Many Latin American countries are highly reliant on the exportation of commodities and their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities. In the past, certain Latin American economies have been influenced by changing supply and demand for a particular currency, monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries), and currency devaluations and revaluations. Other Latin American investment risks may include inadequate investor protection, less developed regulatory, accounting, auditing and financial standards, unfavorable changes in laws or regulations, natural disasters, corruption and military activity. The governments of many Latin American countries may also exercise substantial influence

over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Securities of companies in Latin America may also be subject to significant price volatility.

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed that may have a negative impact on certain securities in which the Fund invests. In addition, litigation regarding any of the securities owned by the Fund may negatively impact the value of a Fund’s shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Sub-Advisor determines to sell such a holding.

WARRANTS RISK. The Fund may invest in warrants. The prices of warrants, which entitle the holder to purchase equity securities at specific prices for a certain period of time, do not necessarily move parallel to the prices of the underlying securities and likely fluctuate more than the prices of the underlying securities. Warrants have no voting rights, receive no dividends, and have no rights with respect to the assets of the issuer.

How to Buy and Sell Shares

Book Entry

upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book-entry or “street name” form.

Share Trading Prices

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objective. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept purchase and redemption orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A "return of capital" is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Investments in Certain Non-U.S. Corporations

If the Fund holds an equity interest in any passive foreign investment companies (“PFICs”), which are generally certain non-U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases

included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by PFICs are not treated as qualified dividend income.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

The Fund's net asset value is determined as of the close of trading (normally 4:00 p.m., Eastern Time) on the New York Stock Exchange (the "NYSE") on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the Fund’s net asset value will be determined as of that time. Net asset value per share is calculated for the Fund by taking the market price of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities , and dividing such amount by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Board or its delegate.

The Fund’s investments are valued daily at market or, in the absence of market value with respect to any investments, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third party pricing services (“Pricing Services”). Fair value prices represent any prices not considered market value prices and are either obtained from a Pricing Service or determined by the Advisor’s pricing committee (the “Pricing Committee”), in accordance with valuation procedures (which may be revised from time to time) adopted by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act. As a general principle, the current “fair value” of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. Valuing the Fund’s assets using fair value pricing can result in using prices for those assets (particularly assets that trade in foreign markets) that may differ from current market valuations.

Certain securities in which the Fund may invest are not listed on any securities exchange or board of trade. Such securities are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market makers exist. Certain securities, particularly debt securities, have few or no trades, or trade infrequently, and information regarding a specific security may not be widely available or may be incomplete. Accordingly, determinations of the fair value of debt securities may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. Typically, Convertible Securities, short-term debt instruments and OTC index credit default swaps are fair valued using information provided by a Pricing Service or obtained from broker-dealer quotations. Short-term debt instruments having a remaining maturity of 60 days or less when purchased are typically valued at cost adjusted for amortization of premiums and accretion of discounts, provided that the Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination.

Equity securities and ETNs listed on any exchange other than Nasdaq and the London Stock Exchange Alternative Investment Market (“AIM”) are typically valued at the last sale price on the exchange on which they are principally traded. Such securities listed on Nasdaq or the AIM are typically valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaqor the AIM, such securities are typically valued using fair value pricing. Such securities traded on more than one securities exchange

are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

Exchange-listed Convertible Securities (if any), exchange-listed equity index futures contracts and exchange-listed index credit default swaps are typically valued at the closing price in the market where such instruments are principally traded. If no official closing price is available, such instruments are fair valued at the mean of their most recent bid and asked price on the exchange on which they are principally traded, if available, and otherwise at their closing bid price.

Forward foreign currency exchange contracts are typically fair valued at the current day’s interpolated foreign exchange rate, as calculated using the current day’s spot rate, and the thirty, sixty, ninety and one-hundred-eighty day forward rates provided by a Pricing Service or by certain independent dealers in such contracts.

Because foreign securities exchanges may be open on different days than the days during which an investor may purchase or sell shares of the Fund, the value of the Fund's securities may change on days when investors are not able to purchase or sell shares of the Fund. Assets denominated in foreign currencies are translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar as provided by a Pricing Service. The value of assets denominated in foreign currencies is converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Fund Service Providers

Brown Brothers Harriman & Co., 50 Post Office Square, Boston, Massachusetts 02110, acts as the administrator, accounting agent, custodian and transfer agent for the Fund. Chapman and Cutler LLP, 111 West Monroe Street, Chicago, Illinois 60603, serves as legal counsel to the Fund. First Trust serves as the fund reporting agent for the Fund.

Total Return Information

The table below compares the total return of the Fund to a market index. The information presented for the Fund is for the period indicated.

Principal Investment Strategies

The Fund is a multi-manager, multi-strategy actively managed exchange-traded fund (“ETF”). First Trust Advisors L.P. is the investment advisor (the “Advisor”) to the Fund. The following will serve as investment sub-advisors (each, a “Sub-Advisor”) to the Fund: First Trust Global Portfolios Limited; Energy Income Partners, LLC; Stonebridge Advisors LLC; and Richard Bernstein Advisors LLC. The Advisor’s Investment Committee determines the Fund’s strategic allocation among various general investment categories and allocates the Fund’s assets to portfolio management teams comprised of personnel of the Advisor and/or a Sub-Advisor (each, a “Management Team”), which employ their respective investment strategies.

The Fund’s investment categories will be: (i) high yield corporate bonds, commonly referred to as “junk” bonds, and first lien senior secured floating rate bank loans; (ii) mortgage-related investments; (iii) preferred securities; (iv) international sovereign bonds, including securities issued by emerging market countries; (v) equity securities of Energy Infrastructure Companies (as defined below), certain of which are referred to as master limited partnerships (“MLPs”); and (vi) dividend paying U.S. exchange-traded equity securities (including common stock) of companies (that may be domiciled in or outside of the United States) and depositary receipts. The Management Teams may utilize a related option overlay strategy and/or derivative instruments in implementing their respective investment strategies for the Fund. The Fund seeks to achieve its objectives by having each Management Team focus on those securities within its respective investment category. The Fund may add or remove investment categories or Management Teams at the discretion of the Advisor. The Advisor expects that the Fund may at times invest significantly in other ETFs, including but not limited to, other ETFs that are advised by the Advisor; accordingly, the Fund may operate principally as a “fund of funds,” but will not necessarily operate as such at all times.

Each Management Team will select the securities for its respective investment category by following the investment strategies set forth below:

High yield corporate bonds and senior loans

In constructing the high yield corporate bonds and first lien senior secured floating rate bank loans (senior loans) portion of the portfolio, the Management Team employs a credit analysis process that involves the evaluation of industry trends, management quality, ownership, collateral adequacy, enterprise value and the consistency of corporate cash flows. This credit analysis process supports the portfolio construction process that considers the macro-economic outlook and near-term economic climate. The Management Team utilizes both the primary and secondary markets. Additional key items that the Management Team considers in the portfolio construction process include relative value assessment, diversification, ongoing monitoring and liquidity. Senior loans are generally considered to be high yield scurrilities, or "junk" bonds.

•

Relative value assessment. Each potential investment opportunity is evaluated relative to other opportunities available in the market.

•

Portfolio. The Management Team seeks to have a broad portfolio across individual issuers and industries. While the portfolio is expected to hold both senior loans and high yield bonds, the allocation between the two assets classes will shift over time as relative value opportunities change.

•

Ongoing monitoring. The Management Team actively monitors the performance of all positions on an ongoing basis.

•

Liquidity. The investment process favors investments in more liquid issuers and the Management Team analyzes the potential liquidity of each investment opportunity prior to purchase.

Mortgage-related investments

In constructing the mortgage-related investments portion of the portfolio, the Management Team considers sector analysis, security analysis, total return scenario analysis and surveillance. The mortgage-related investments in which the Fund may invest include mortgage-backed securities (such as residential mortgage-backed securities and commercial mortgage-backed securities), mortgage dollar rolls and to-be-announced transactions. The mortgage-backed securities in which the Fund invests may include non-agency sponsored mortgage-backed securities.

•

Sector analysis. The Management Team performs top-down review of core mortgage-backed securities sectors and macro-economic market trends based on bottom-up analysis of individual securities to determine the sectors in which the Fund will be overweight, neutral weight and underweight.

•

Security analysis. The Management Team evaluates individual securities based on criteria such as price, yield, rating and option adjusted spreads, prepayment sensitivity and forecasting, default risk, interest rate duration and key rate exposure, sensitivity to yield volatility, liquidity premium and normalized valuation for each security class.

•

Total return scenario analysis. The Management Team performs individual security and portfolio level return analysis using extensive scenario stress testing of yield curve and spread shocks and/or movements.

•

Surveillance. The Management Team analyzes holdings on a systematic basis to monitor any changes in security and portfolio performance or meaningful changes in risk measures.

•

Performance attribution. The Management Team performs granular total return analysis by reviewing key portfolio attributes such as duration, yield curve positioning and sector allocations, as well as spreads. The portfolio’s performance is also compared to various benchmarks.

Preferred securities

In constructing the preferred and hybrid securities portion of the portfolio, the Management Team considers the following factors. Hybrid preferred securities are typically junior and fully subordinated liabilities of an issuer or the beneficiary of a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. Certain of the hybrid securities held by the fund may be issued by companies operating in emerging markets.

•

Credit analysis. The Management Team performs bottom-up fundamental credit research on issuers and individual security characteristics to determine suitability for the investment portfolio.

•

Sector analysis. The Management Team performs top-down sector and industry analysis to aid in determining appropriate sector weightings and overall credit risk of the portfolio.

•

Regulatory analysis. The Management Team performs top-down analysis of the impact of regulatory changes for each sector as it relates to credit worthiness.

•

Macro-economic and interest rate analysis. The Management Team performs analysis of macro-economic conditions and interest rate trends to determine an appropriate duration target and overall credit and interest rate risk for the portfolio.

•

Relative value analysis. The Management Team determines the relative value of individual preferred and hybrid securities for inclusion in the portfolio by analyzing new issues and secondary market securities based on various measures of credit spread to treasuries/other credit spread products, various measures of yield, call/ extension risk, credit quality, capital structure positioning, duration and individual security characteristics.

•

Technical market analysis. The Management Team analyzes trading patterns, market liquidity, deal sizes, new issuance trends and interest rate conditions to evaluate market conditions.

International sovereign bonds

In constructing the international sovereign bonds portion of the portfolio, the Management Team focuses on a two-way adaptive process, which combines the Management Team’s current fundamental economic assessment with available risk premiums to determine the optimal risk/reward mix for the portfolio. Certain of the international sovereign bonds held by the Fund may be considered to be high yield securities, or "junk" bonds. The process includes the following considerations.

•

The Management Team determines the strategic outlook by assessing structural macro-economic themes, such as debt burdens, inflation, politics and capital flows together with shorter term market drivers like valuations, liquidity and sentiment.

•

The Management Team analyzes the relevant risk premiums and factors impacting underlying issuers and securities in the investable universe by looking at various quantitative and qualitative measures. The core risk premiums are considered to be interest rate risk, credit risk and currency risk.

•

The Management Team translates the strategic outlook into exposures to the desired risk premiums expressing the Management Team’s conviction levels, time horizons and risk tolerances consistent with macro-economic scenarios. The portfolio is actively allocated across the investment universe by selecting those issuers and securities that provide the desired interest rate, credit and currency risk exposures. Consideration is also given to individual security liquidity and suitability for the portfolio.

•

The Management Team will seek to add exposure to individual issuers, securities or currencies that it views as undervalued compared to its assessment of the issuer, security or currency’s fair market value. Relative and absolute valuation metrics are used comparing yield, spread, interest rate differentials and overbought/over- sold indicators among others.

•

The Management Team will provide ongoing portfolio monitoring so that the portfolio maintains its exposure to the Management Team’s desired risk premiums. Systems and controls in place monitor overall portfolio risk and also ensure adherence to mandates and regulatory constraints.

Energy Infrastructure Companies

Energy Infrastructure Companies are publicly-traded MLPs or limited liability companies that are taxed as partnerships; entities that control MLPs, entities that own general partner interests in an MLP, or MLP affiliates (such as I-shares or I-units); U.S. and Canadian energy yield corporations (“yieldcos”); pipeline companies; utilities; and other companies that are involved in operating or providing services in support of infrastructure assets such as pipeline, power transmission, terminalling and petroleum and natural gas storage in the petroleum, natural gas and power generation industries. In constructing the Energy Infrastructure Companies portion of the portfolio, the Management Team utilizes the following three step investment process: (1) defining the universe of companies in the energy sector and energy utilities industries that have high dividend payout ratios and/or are involved in the energy infrastructure business; (2) identifying, among this universe, companies that pass a quality threshold established by the Management Team; and (3) constructing the portfolio by determining the portfolio weighting of companies that have made it through the first two steps.

In step 1, the Management Team defines the universe by seeking energy sector and energy utilities companies weighted towards:

•

Regulated monopoly or monopoly-like assets (i.e., companies that own unique assets that provide for a sustainable competitive advantage due to control of location);

•

Non-cyclical cash flows (i.e., companies that have most or all of their assets in businesses whose revenues tend not to fluctuate with commodity prices and tend to be less sensitive to changes in the economic cycle);

•

Fee-for-service revenues (i.e., companies that have most or all of their assets in businesses whose revenues are not tied to changes in commodity prices and/or volumes actually shipped through or stored in their facilities); and

•

Cost escalators (i.e., companies that have most or all of their assets in businesses whose revenues and/or margins can be adjusted to compensate for changes in the company’s costs).

In step 2, the Management Team identifies companies that pass a quality threshold established by the Management Team by utilizing both quantitative aspects to measure quality, such as the stability of cash flows, returns on invested capital, financial leverage and earnings coverage of dividends, as well as qualitative aspects, such as the confidence that the Management Team has in a company’s management and the quality of its assets.

In step 3, the Management Team constructs the portfolio by determining the portfolio weighting of companies that have made it through the first two steps. The Management Team will balance each position’s expected rate of return against risks, limitations on position sizes and Fund’s portfolio limitations.

Equity securities

In constructing the equity securities portion of the portfolio, the Management Team utilizes the following investment process.

•

Construct a universe with all the equity securities that are listed on U.S. exchanges, including American depositary receipts (“ADRs”) but excluding preferred securities, master limited partnerships and mortgage real estate investment trusts (“REITs”). Certain of the ADRs in which the Fund invests may be issued by companies operating in emerging markets.

•

Create a global high dividend yield universe by removing companies with a yield that is less than the market average and also by removing the highest ranked yields, which are considered to have a higher risk of a future dividend cut.

•

The Management Team examines the sustainability of dividends on the global high dividend yield universe by screening for debt levels below the market average, earnings growth and consistency of earnings.

•

The Management Team applies a proprietary mean-variance optimization (MVO) method to risk-weight the stocks. The MVO process also limits security weights to approximately 4% of the equity portion of the portfolio and applies sector/industry caps and minimum thresholds for price-per-share, liquidity (average daily trading volume) and market-capitalization.

The Fund may invest in the securities within the investment categories directly or, alternatively, may invest in other ETFs that generally provide exposure to those categories. Any other ETFs in which the Fund invests to gain exposure to an investment category may be subject to investment parameters that differ in certain respects from those that have been established for such investment category. In general, ETFs will be selected for the Fund to provide exposure to the various investment categories or to achieve diversification within an investment category. ETFs may also be used for defensive purposes or to equitize cash.

To enhance expected return, the Advisor may periodically tactically adjust investment category weights. Security selection is performed for the Fund by the Advisor and/or a Sub-Advisor.

In general, the fixed income securities in which the Fund invests may be issued by U.S. and non-U.S. issuers, of any capitalization range or credit quality, including high yield securities. The high yield securities in which the Fund invests are rated below investment grade at the time of purchase or unrated and deemed by the Advisor to be of comparable quality, commonly referred to as “junk” bonds. In addition, the fixed income securities in which the Fund will invest may have effective or final maturities of any length.

The Fund may invest in the equity securities, including preferred securities, of non-U.S. issuers, either directly or through investments that are in the form of depositary receipts. The Fund expects that the depositary receipts in which it invests will be exchange-traded and will not include unsponsored depositary receipts. The Fund may invest in equity securities issued by small, mid or large capitalization companies. The portion of the Fund’s net assets that are denominated in currencies other than the U.S. dollar is not expected to exceed 30%.

The Fund may invest in derivative instruments for various purposes, including to hedge investments or to enhance return. In general, the Fund may invest in exchange-listed futures contracts, exchange-listed options, exchange-listed options on futures contracts, exchange-listed stock index options and forward contracts. In addition, the Fund expects to enter into certain types of derivatives transactions with respect to certain of the particular investment categories described above.

Principal Risks

COVENANT-LITE LOANS RISK. Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle.

the underlying security declines in value. The Fund will have no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security. A number of factors may influence the option holder’s decision to exercise the option, including the value of the underlying security, price volatility, dividend yield and interest rates. To the extent that these factors increase the value of the call option, the option holder is more likely to exercise the option, which may negatively affect the Fund.

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

DIVIDENDS RISK. The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of an issuer’s track record of paying dividends. Companies that issue dividend-paying securities are not required to continue to pay dividends on such securities. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future, which could negatively affect the Fund’s performance.

EMERGING MARKETS RISK. Investments in securities issued by governments and companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. For funds that track an index or are managed based upon a benchmark, the index may not weight the securities in emerging market countries on the basis of investor protection limitations, financial reporting quality or available oversight mechanisms. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

ENERGY INFRASTRUCTURE COMPANIES RISK. Energy infrastructure companies are subject to risks specific to the energy and energy-related industries. This includes but is not limited to: fluctuations in commodity prices impacting the volume of energy commodities transported, processed, stored or distributed; reductions in volumes of natural gas or other energy commodities being available for transporting, processing, storing or distributing; slowdowns in new construction and acquisitions limiting growth potential; reduced demand for oil, natural gas and petroleum products, particularly for a sustained period of time; depletion of natural gas reserves or other commodities; rising interest rates resulting in higher costs of capital, increased operating costs; counterparties to contracts defaulting or going bankrupt; and an inability to execute acquisitions or expansion projects in a cost-effect manner; extreme weather events and environmental hazards; and threats of attack by terrorists on energy assets. Energy infrastructure companies may also face counterparty risk, such that long-term contracts may be declared void if the counterparty to those contracts enters bankruptcy proceedings. In addition, energy infrastructure companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of energy infrastructure companies. Natural disasters, such as hurricanes in the Gulf of Mexico, also may impact the energy infrastructure companies.

ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities underlying the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

FLOATING RATE SECURITIES RISK. Floating rate securities are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. As a result, the coupon on floating rate securities will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the security. A floating rate security’s coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate securities may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate which would decrease the value of the security.

FORWARD CONTRACTS RISK. A forward contract is an over-the-counter derivative transaction between two parties to buy or sell a specified amount of an underlying reference at a specified price (or rate) on a specified date in the future. Forward contracts are negotiated on an individual basis and are not standardized or traded on exchanges. The market for forward contracts is substantially unregulated and can experience lengthy periods of illiquidity, unusually high trading volume and other negative impacts, such as political intervention, which may result in volatility or disruptions in such markets. A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. Forward contracts can increase the Fund’s risk exposure to underlying references and their attendant risks, such as credit risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and valuation risk, among others.

HYBRID CAPITAL SECURITIES RISK. Hybrid capital securities are subject to the risks of equity securities and debt securities. The claims of holders of hybrid capital securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid capital securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances be even more volatile than traditional equity securities. At the same time, hybrid capital securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. The terms of hybrid capital securities may vary substantially and the risks of a particular hybrid capital security will depend upon the terms of the instrument, but may include the credit risk of the issuer, as well as liquidity risk, since they often are customized to meet the needs of an issuer or a particular investor, and therefore the number of investors that buy such instruments in the secondary market may be small.

the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

payments in loan pools created by non-government issuers. Securities issued by private issuers are subject to the credit risks of the issuers. An unexpectedly high rate of defaults on the loan pool may adversely affect the value of a non-agency security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of pools that include subprime loans. Non-agency securities are typically traded “over-the-counter” rather than on a securities exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, the non-agency mortgage-related securities held by the Fund may be particularly difficult to value because of the complexities involved in assessing the value of the underlying loans.

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund's portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund's ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options.

for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

REIT RISK. REITs typically own and operate income-producing real estate, such as residential or commercial buildings, or real-estate related assets, including mortgages. As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.

resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

SOVEREIGN AND QUASI-SOVEREIGN DEBT SECURITIES RISK. Sovereign and quasi-sovereign debt securities are issued or guaranteed by foreign governmental entities. Investments in such securities are subject to the risk that the relevant sovereign government or governmental entity may delay or refuse to pay interest or repay principal on its debt. Such delays or refusals may be due to cash flow problems, insufficient foreign currency reserves, political considerations, the size of its debt relative to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. There is no legal process for collecting sovereign debt that is not repaid, nor are there bankruptcy proceedings through which all or part of the unpaid sovereign debt may be collected.

Additional Information on the Fund's Investment Objectives and Strategies

The Fund is a series of First Trust Exchange-Traded Fund IV and is regulated as an “investment company” under the 1940 Act. The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objectives are fundamental and may not be changed without approval by the holders of a majority of the outstanding voting securities of the Fund. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. If there is a material change to the Fund’s principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objectives.

Additional Information on the Fund’s Strategy

In selecting securities for the Fund, the investment strategy of the Management Teams is driven by comprehensive analysis with a goal of investing in securities with the highest expected total return, adjusted for risk. The Fund is seeking risk-adjusted income and capital appreciation through the use of multiple asset classes, targeted investment strategies and specialized Management Teams. The Fund will use multiple specialist managers and tailored investment strategies to offer an innovative approach to generating income. The Management Teams intend to exercise flexibility in purchasing assets that can act as a complement to traditional fixed income holdings.

Fund Investments

The investment categories in which the Fund invests and the investment strategies that the applicable Management Teams pursue are described below.

Principal Investments

High Yield Corporate Bonds and Senior Loans

The Fund intends to invest between 0% and 30%, but may invest up to 50%, of its net assets in a combination of high yield corporate bonds and senior loans. High yield corporate bonds are usually rated below investment grade and are commonly referred to as “junk” bonds. Such bonds and loans in which the Fund invests directly will be issued by entities domiciled in the United States. Under normal market conditions, the Fund will seek to invest at least 75% of its net assets that are invested in such bonds and loans (in the aggregate) in bonds and loans that, at the time of original issuance, have at least $100 million par amount outstanding.

The high yield corporate bonds in which the Fund invests will usually be rated below investment grade at the time of purchase or unrated and deemed by the Advisor and/or the applicable Management Team to be of comparable quality. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. High yield debt may be issued, for example, by companies without long track records of sales and earnings or by issuers that have questionable credit strength. Corporate bonds may carry fixed or floating rates of interest.

The senior loans in which the Fund will invest will represent amounts borrowed by companies or other entities from banks and other lenders. In many cases, senior loans are issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancings. A significant portion of the senior loans in which the Fund will invest are expected to be rated below investment grade or unrated.

A senior loan is considered senior to all other unsecured claims against the borrower, and senior to or pari passu with all other secured claims, meaning that in the event of a bankruptcy, the senior loan, together with all other first lien claims, is entitled to be the first to be repaid out of the proceeds of the assets securing the loans, before other existing unsecured claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances, which take precedence. Senior loans have interest rates that reset periodically. The interest rates on senior loans are generally based on a percentage above the London Interbank Offered Rate (LIBOR), a U.S bank’s prime or base rate, the overnight federal funds rate, or another rate. Senior loans may be structured and administered by a financial institution that acts as the agent of the lenders participating in the senior loan. The Fund will generally invest in senior loans that the Advisor and/or the applicable Management Team deems to be liquid with readily available prices. The Management Team does not intend to purchase senior loans that are in default; however, the Fund may hold a senior loan that has defaulted subsequent to the purchase by the Fund.

The senior loan market has seen a significant increase in loans with few or none of the financial maintenance covenants (i.e., “covenant-lite loans”) that have traditionally protected lenders including more aggressive terms that favor borrowers with respect to restrictions regarding additional debt, payment terms, income requirements and asset dispositions. A substantial amount of the senior loans held by the Fund are expected to be covenant-lite loans, meaning the Fund may be unable to declare an event of default if financial performance deteriorates, renegotiate the terms of the loan based upon the elevated risk levels or take other actions to help mitigate losses.

Mortgage-Related Investments

The Fund intends to invest between 0% and 30%, but may invest up to 50%, of its net assets in mortgage-related debt securities and other mortgage-related instruments (collectively, “Mortgage-Related Investments”).

The Fund generally expects that the Mortgage-Related Investments in which it invests will primarily consist of investment grade securities (i.e., securities with credit ratings within the four highest rating categories of a nationally recognized statistical rating organization (“NRSRO”)) at the time of purchase. The Mortgage-Related Investments in which the Fund invests include mortgage-backed securities (such as residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”)). Mortgage-backed securities represent an interest in a pool of mortgage loans made by banks and other financial institutions to finance purchases of homes, commercial buildings and other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors. As the underlying mortgage loans are paid off, investors receive principal and interest payments. Mortgage-backed securities may be fixed-rate or adjustable-rate mortgage-backed securities (ARMS). Certain mortgage-backed securities (including RMBS and CMBS), where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest, are referred to as stripped mortgage-backed securities (SMBS). Further, mortgage-backed securities can also be categorized as collateralized mortgage obligations (CMOs) or real estate mortgage investment conduits (REMICs) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets.

The mortgage-backed securities in which the Fund invests may be, but are not required to be, issued or guaranteed by the U.S. government, its agencies or instrumentalities, such as Ginnie Mae and U.S. government-sponsored entities, such as Fannie Mae and Freddie Mac. Government agency or instrumentality securities have different levels of credit support. For example, Ginnie Mae securities carry a guarantee as to the timely repayment of principal and interest that is backed by the full faith and credit of the U.S. government. However, the full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. Fannie Mae and Freddie Mac pass-through mortgage certificates are backed by the credit of the respective instrumentality and are not guaranteed by the U.S. government. Other securities issued by government agencies or instrumentalities, including government-sponsored entities, may only be backed by the creditworthiness of the issuing institution, not the U.S. government, or the issuers may have the right to borrow from the U.S. Treasury to meet their obligations. Many mortgage-backed securities are pass-through securities, which means they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately. Adjustable-rate mortgage-backed securities include ARMS and other mortgage-backed securities with interest rates that adjust periodically to reflect prevailing market rates.

The Fund may also invest in to-be-announced transactions (“TBA Transactions”). A TBA Transaction is a method of trading mortgage-backed securities. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price. The actual pools delivered generally are determined two days prior to the settlement date.

Further, the Fund may enter into short sales as part of its overall portfolio management strategies or to offset a potential decline in the value of a security; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets that are invested in Mortgage-Related Investments. To the extent

required under applicable federal securities laws, rules, and interpretations thereof, the Fund will “set aside” liquid assets or engage in other measures to “cover” open positions and short positions held in connection with the foregoing types of transactions.

Preferred Securities

The Fund intends to invest between 0% and 30%, but may invest up to 50%, of its net assets in preferred securities. Certain of the preferred securities in which the Fund invests are traditional preferred stocks which issue dividends that qualify for the dividends received deduction under which “qualified” domestic corporations are able to exclude a percentage of the dividends received from their taxable income. Certain of the preferred securities in which the Fund invests are preferred stock that does not issue dividends that qualify for the dividends received deduction or generate qualified dividend income. Hybrid preferred securities, another type of preferred securities, are typically junior and fully subordinated liabilities of an issuer or the beneficiary of a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. Preferred securities held by the Fund generally pay fixed or adjustable-rate distributions to investors and have preference over common stock in the payment of distributions and the liquidation of a company’s assets, which means that a company typically must pay dividends or interest on its preferred securities before paying any dividends on its common stock. Preferred securities are generally junior to all forms of the company’s debt, including both senior and subordinated debt.

International Sovereign Debt

The Fund intends to invest between 0% and 30%, but may invest up to 50%, of its net assets in debt securities, including inflation-linked bonds, issued by foreign governments or their subdivisions, agencies and government-sponsored enterprises (“Sovereign Debt”). Sovereign Debt may include bonds, notes or other debt obligations denominated in local currencies, Euros or U.S. dollars, as well as issues denominated in emerging market local currencies that are issued by “supranational issuers,” such as the International Bank for Reconstruction and Development and the International Finance Corporation, as well as development agencies supported by other national governments. According to the applicable Management Team, while there is no universally accepted definition of what constitutes an “emerging market,” in general, emerging market countries are characterized by developing commercial and financial infrastructure with significant potential for economic growth and increased capital market participation by foreign investors. At least 50% of the Fund’s net assets that are invested in Sovereign Debt will be invested in securities of issuers rated investment grade (BBB-/ Baa3 or higher) at the time of purchase by at least one NRSRO, and unrated securities judged to be of comparable quality by the applicable Management Team. Up to 50% of the Fund’s net assets invested in Sovereign Debt may be invested in securities of issuers rated below investment grade at the time of purchase (i.e., “junk” bonds). If a security or issuer of Sovereign Debt is rated by multiple NRSROs and receives different ratings, the Fund will treat the security or issuer (as applicable) as being rated in the highest rating category received from a NRSRO.

The Fund intends to invest in Sovereign Debt of issuers in both developed and emerging markets. In addition, the Fund expects that, under normal market conditions, at least 80% of the Sovereign Debt in which it invests will be issued by issuers with outstanding debt of at least $200 million (or the foreign currency equivalent thereof).

Equity Securities of Energy Infrastructure Companies

The Fund intends to invest between 0% and 50% of its net assets in exchange-traded equity securities of companies deemed by the applicable Management Team to be engaged in the energy infrastructure sector. These companies principally include U.S. and Canadian natural gas and electric utilities, corporations operating energy infrastructure assets such as pipelines or renewable energy production, publicly-traded master limited partnerships and limited liability companies taxed as partnerships (“MLPs”), MLP affiliates (including entities that control MLPs, entities that own general partner interests in an MLP), U.S. and Canadian yield corporations (“yieldcos”), utilities, and other companies that are involved in operating or providing services in support of infrastructure assets such as pipelines, power transmission, terminalling and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, “Energy Infrastructure Companies”).

The Fund may invest in the equity securities of MLPs, which are limited partnerships whose shares (or units) are listed and traded on a U.S. securities exchange. MLP units may be common or subordinated. In addition, the Fund may invest in I-Shares, which represent an ownership interest issued by an affiliated party of an MLP. The MLP affiliate uses the proceeds from the sale of I-Shares to purchase limited partnership interests in the MLP in the form of i-units. I-units have similar features as MLP common units in terms of voting rights, liquidation preference and distributions. However, rather than receiving cash, the MLP affiliate receives additional i-units in an amount equal to the cash distributions received by MLP common units. Similarly, holders of I-Shares will receive additional I-Shares, in the same proportion as the MLP affiliates’ receipt of i-units, rather than

cash distributions. I-Shares themselves have limited voting rights which are similar to those applicable to MLP common units. I-Shares are listed and traded on a U.S. national securities exchange.

Dividend Paying U.S. Exchange-Traded Equity Securities and Depositary Receipts and Related Option Overlay Strategy

The Fund intends to invest between 0% and 30%, but may invest up to 50%, of its net assets in dividend paying U.S. exchange-traded equity securities (including common stock) of companies (that may be domiciled in or outside of the United States) and depositary receipts. For the avoidance of doubt, this investment category and these percentages will not include investments in preferred securities (described above under “Preferred Securities”), investments in those equity securities that are included in “Equity Securities of Energy Infrastructure Companies” (as described above), or investments in ETFs that are intended to provide exposure to any of the other five investment categories.

The Management Team may utilize a related option overlay strategy and/or derivative instruments in implementing their respective investment strategies for the Fund. To implement this strategy, the Fund will write (sell) covered U.S. exchange-traded call options in order to seek additional cash flow in the form of premiums on the options. The market value of the option overlay strategy may be up to 30% of the Fund’s overall net asset value and the notional value of the calls written may be up to 30% of the overall Fund. The maturity of the options utilized will generally be between one week and three months. The options written may be in-the-money, at-the-money or out-of-the-money. Out-of-the-money options are less expensive than in-the-money options, but out-of-the-money options have no intrinsic value and are also regarded as bearing higher risk as there is a greater probability that they will end up being worthless upon expiration. Out-of-the-money options may be more volatile and often experience larger percent gains/losses than the in-the-money options.

Derivative Instruments

The Fund may invest in derivative instruments. Not including the option overlay strategy, no more than 20% of the value of the Fund’s net assets will be invested in derivative instruments (the “20% Limitation”). In general, the Fund may invest in exchange-listed futures contracts, exchange-listed options, exchange-listed options on futures contracts, and exchange-listed stock index options.

Primarily in connection with its investments in Sovereign Debt (but, to the extent applicable, in connection with other investments), the Fund may actively manage its foreign currency exposures, including through the use of forward currency contracts, non-deliverable forward currency contracts, exchange-listed currency futures and exchange-listed currency options; such derivatives use will be included for purposes of determining compliance with the 20% Limitation. The Fund may, for instance, enter into forward currency contracts in order to “lock in” the exchange rate between the currency it will deliver and the currency it will receive for the duration of the contract and may buy or sell exchange-listed futures contracts on U.S. Treasury securities, non-U.S. government securities and major non-U.S. currencies.

The Fund will comply with the regulatory requirements of the Securities and Exchange Commission to maintain assets as “cover,” maintain segregated accounts, and/or make margin payments when it takes positions in derivative instruments involving obligations to third parties (i.e., instruments other than purchase options). If the applicable guidelines prescribed under the 1940 Act so require, the Fund will earmark or set aside cash, U.S. government securities, high grade liquid debt securities and/or other liquid assets permitted by the Securities and Exchange Commission in a segregated custodial account in the amount prescribed. The Fund will only enter into transactions in derivative instruments with counterparties that the Advisor and/or the applicable Management Team reasonably believes are capable of performing under the applicable contract. The Fund’s investments in derivative instruments will be consistent with the Fund’s investment objectives and the 1940 Act and will not be used to seek to achieve a multiple or inverse multiple of an index.

Investment Companies and Other Pooled Investment Vehicles

The Fund may invest in securities of investment companies, including ETFs, some of which may be ETFs that are advised by the Advisor. The Fund’s ability to invest in other investment companies is limited by the 1940 Act and the related rules and interpretations. The Fund may invest in other investment companies in excess of the limits imposed under the 1940 Act pursuant to exemptive orders obtained by certain investment companies and their sponsors from the Securities and Exchange

Commission, subject to certain conditions and pursuant to a contractual arrangement between the Fund and such investment companies. ETFs trade on a securities exchange and their shares may, at times, trade at a premium or discount to their net asset value.

In general, as a shareholder of an investment company, the Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the fund’s advisory and administrative fees with respect to assets so invested. Share- holders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. However, pursuant to a contractual agreement, the Advisor has agreed to reduce the management fee paid by the Fund by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided, that, the investment companies are advised by the Advisor. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed- end investment companies.

Non-Principal Investments

Cash Equivalents and Short-Term Investments

The Fund may invest up to 20% of its net assets in short-term debt securities, money market funds and other cash equivalents, or it may hold cash. The percentage of the Fund invested in such holdings will vary and will depend on several factors, including market conditions. For temporary defensive purposes, during the initial invest-up period and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities or it may hold cash. During such periods, the Fund may not be able to achieve its investment objectives. The Fund may adopt a defensive strategy when the Advisor believes securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances.

Short-term debt securities are securities from issuers having a long-term debt rating of at least A by S&P Ratings, Moody’s or Fitch and having a maturity of one year or less. The use of temporary investments will not be a part of a principal investment strategy of the Fund.

Short-term debt securities are defined to include, without limitation, the following: (i) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities; (ii) short-term securities issued or guaranteed by non-U.S. governments or by their agencies or instrumentalities; (iii) certificates of deposit issued against funds deposited in a bank or savings and loan association; (iv) bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions; (v) repurchase agreements, which involve purchases of debt securities; (vi) bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest; and (vii) commercial paper, which is short-term unsecured promissory notes. The Fund may only invest in commercial paper rated A-1 or higher by S&P Ratings, Prime-1 or higher by Moody’s or F1 or higher by Fitch.

Junior Loans

The Fund may invest up to 15% of its net assets in secured loans that are not first lien loans or loans that are unsecured (collectively referred to as “junior loans”). Junior loans have the same characteristics as senior loans except that junior loans are not first in priority of repayment and/or may not be secured by collateral.

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objectives. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CALL RISK. Some debt securities may be redeemed at the option of the issuer, or “called,” before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. A Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. A Fund would then be forced to invest the unanticipated proceeds at lower interest rates, likely resulting in a decline in the Fund’s income. Such redemptions and subsequent reinvestments would also increase a Fund’s portfolio turnover. If a called debt security was purchased by a Fund at a premium, the value of the premium may be lost in the event of a redemption.

CASH TRANSACTIONS RISK. The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A Fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

ownership. A bail-in of a financial institution may result in a reduction in value of some or all of securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, the Fund may also be similarly impacted.

COVENANT-LITE LOANS RISK. The loan agreement, which sets forth the terms of a loan and the obligations of the borrower and lender, contains certain covenants that mandate or prohibit certain borrower actions, including financial covenants that dictate certain minimum and maximum financial performance levels. Covenants that require the borrower to maintain certain financial metrics during the life of the loan (such as maintaining certain levels of cash flow and limiting leverage) are known as “maintenance covenants.” These covenants are included to permit the lender to monitor the performance of the borrower and declare an event of default if breached, allowing the lender to renegotiate the terms of the loan based upon the elevated risk levels or take other actions to help mitigate losses. Covenant-lite loans contain fewer or no maintenance covenants making an investment in these types of loans inherently riskier than an investment in loans containing provisions allowing the lender reprice credit risk associated with the borrower or restructure a problematic loan. Since 2013, the number of covenant-lite loans issued has increased significantly. The Fund’s elevated exposure to such loans during a downturn in the credit cycle could cause the Fund to experience outsized losses.

COVERED CALL RISK. The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The premiums received from the options may not be sufficient to affect any losses sustained from the underlying stocks over time. The Fund will have no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security. A number of factors may influence the option holder’s decision to exercise the option, including the value of the underlying security, price volatility, dividend yield and interest rates. To the extent that these factors increase the value of the call option, the option holder is more likely to exercise the option, which may negatively affect the Fund. In addition, the Fund’s ability to sell the securities underlying the options will be limited while the options are in effect unless the Fund cancels out the option position through the purchase of offsetting identical options prior to the expiration of the written options. Exchanges may suspend the trading of options in volatile markets which may prohibit the Fund from writing options at times the portfolio managers deem advisable.

coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Advisor, distributor and other service providers (including, but not limited to, sub-advisors, index providers, fund accountants, custodians, transfer agents and administrators), market makers, authorized participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses; interference with the Fund’s ability to calculate its net asset value; disclosure of confidential trading information; impediments to trading; submission of erroneous trades or erroneous creation or redemption orders; the inability of the Fund or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines penalties, reputational damage, reimbursement or other compensation costs; or additional compliance costs. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. However, there is no guarantee that such efforts will succeed, and the Fund and its shareholders could be negatively impacted as a result.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

DIVIDENDS RISK. The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of an issuer’s track record of paying dividends. Companies that issue dividend-yielding securities are not required to continue to pay dividends on such securities. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future especially if the companies are facing an economic downturn, which could negatively affect the Fund’s performance.

EMERGING MARKETS RISK. Investments in securities issued by governments and companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed market countries. Moreover, emerging market countries often have less uniformity in accounting and reporting requirements, unsettled securities laws, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging market countries often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. and other developed market countries. In addition, significant delays may occur in registering the transfer of securities. Settlement or registration problems may make it more difficult for the Fund to value its portfolio securities and could cause the Fund to miss attractive investment opportunities. Investing in emerging market countries involves a higher risk of expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries. Enforcing legal rights may be made difficult, costly and slow in emerging markets as there may be additional problems enforcing claims against non-U.S. governments.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests.Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

ETF RISK. Most ETFs use a “passive” investment strategy and seek to replicate the performance of a market index. Such ETFs do not take defensive positions in volatile or declining markets their shares may trade below net asset value. While some ETFs seek to achieve the same return as a particular market index, the performance of the ETF may diverge from the performance of the index. Some ETFs are actively managed ETFs and do not track a particular index which indirectly subjects an investor to active management risk. An active secondary market in ETF shares may not develop or be maintained and may be halted or interrupted due to actions by its listing exchange, unusual market conditions or other reasons. There can be no assurance that an ETF’s shares will continue to be listed on an active exchange. In addition, shareholders bear both their proportionate share of the Fund’s expenses and, indirectly, the ETF’s expenses, incurred through the Fund’s ownership of the ETF. Because the expenses and costs of an ETF are shared by its investors, redemptions by other investors in the ETF could result in decreased economies of scale and increased operating expenses for such ETF. These transactions might also result in higher brokerage, tax or other costs for the ETF. This risk may be particularly important when one investor owns a substantial portion of the ETF. There is a risk that ETFs in which the Fund invests may terminate due to extraordinary events. For example, any of the service providers to ETFs, such as the trustee or sponsor, may close or otherwise fail to perform their obligations to the ETF, and the ETF may not be able to find a substitute service provider. Also, certain ETFs may be dependent upon licenses to use various indexes as a basis for determining their compositions and/or otherwise to use certain trade names. If these licenses are terminated, the ETFs may also terminate. In addition, an ETF may terminate if its net assets fall below a certain amount.

FLOATING RATE SECURITIES RISK. Floating rate securities are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate security is set in the loan agreement at the level of a widely followed interest rate, plus a fixed spread. As a result, it is expected that when interest rates change, the value of floating rate securities will fluctuate less than the value fixed rate debt securities. The coupon on floating rate securities will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the security. A floating rate security’s coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates and may effect the value of the security. Floating rate securities may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate which would decrease the value of the security. The secondary market value of a floating rate security is based on the volatility of the reference rate, the time remaining to maturity, the outstanding amount of such securities, market interest rates and the credit quality or perceived financial status of the issuer. Floating rate securities may be less liquid than other types of securities.

risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and valuation risk, among others.

HYBRID CAPITAL SECURITIES RISK. Hybrid capital securities are securities which contain characteristics of both debt and equity securities and are subject to many of the same risks as equity and debt securities. The claims of holders of hybrid capital securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid capital securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances be even more volatile than traditional equity securities. At the same time, hybrid capital securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. Hybrid capital securities may also be more limited in their rights to participate in management decisions of an issuer (such as voting for the board of directors). The terms of hybrid capital securities may vary substantially and the risks of a particular hybrid capital security will depend upon the terms of the instrument. Certain hybrid capital securities may be more thinly traded and less liquid than either publicly issued equity or debt securities, especially hybrid capital securities that are “customized” to meet the needs of particular investors, potentially making it difficult for the Fund to sell such securities at a favorable price or at all. Any of these features could cause a loss in market value of hybrid capital securities held by the Fund or otherwise adversely affect the Fund.

decline. This risk is more prevalent with respect to debt securities held by the Fund. Inflation creates uncertainty over the future real value (after inflation) of an investment. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund investors.

the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in the MLP being required to pay U.S. federal income tax (as well as state and local income taxes) on its taxable income at the applicable corporate tax rate. This would have the effect of reducing the amount of cash available for distribution by an MLP and could result in a significant reduction in the value of the Fund’s investment. The classification of an MLP as a corporation for U. S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP’s current or accumulated earnings and profits. To the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in the amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Furthermore, any return of capital distribution received from an MLP may require the Fund to restate the character of its distributions and amend any shareholder tax reporting previously issued.

financial information about the issuers, less market liquidity, more market volatility and political instability. Future political and economic developments, the possible imposition of withholding taxes on dividend income, the possible seizure or nationalization of non-U.S. holdings, the imposition of sanctions by foreign governments, the possible establishment of capital controls, exchange controls or freezes on the convertibility of currency or the adoption of other governmental restrictions might adversely affect an investment in non-U.S. securities. Additionally, non-U.S. issuers may be subject to less stringent regulation, and to different accounting, auditing and recordkeeping requirements. The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other regional developments particular to a given country or region.

OPTIONS RISK. The Fund may utilize options. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund's portfolio manager to forecast market movements correctly. The prices of options are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. As a seller (writer) of a put option, the seller will tend to lose money if the value of the reference index or security falls below the strike price. As the seller (writer) of a call option, the seller will tend to lose money if the value of the reference index or security rises above the strike price. As the buyer of a put or call option, the buyer risks losing the entire premium invested in the option if the buyer does not exercise the option. The effective use of options also depends on the Fund's ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Options may also involve the use of leverage, which could result in greater price volatility than other markets.

OTC DERIVATIVES RISK. The Fund may utilize derivatives that are traded over-the-counter, or “OTC.” In general, OTC derivatives are subject to the same risks as derivatives generally, as described throughout. However, because OTC derivatives do not trade on an exchange, the parties to an OTC derivative face heightened levels of counterparty risk, liquidity risk and valuation risk. To the extent that the Fund utilizes OTC derivatives, its counterparty risk will be higher if it only trades with a single or small number of counterparties. The secondary market for OTC derivatives may not be as deep as for other instruments and such instruments may experience periods of illiquidity. In addition, some OTC derivatives may be complex and difficult to value. Under certain market conditions it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a particular derivative transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

negatively impact the return of the preferred security held by the Fund. Preferred securities may also be substantially less liquid than other securities, including common stock.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

REIT RISK. The Fund may invest in closed-end funds and/or ETFs that hold REITs. REITs typically own and operate income-producing real estate, such as residential or commercial buildings, or real-estate related assets, including mortgages. As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. Additionally, investing in REITs involves certain other risks related to their structure and focus, which include, but are not limited to, dependency upon management skills, limited diversification, the risks of locating and managing financing for projects, heavy cash flow dependency, possible default by borrowers, the costs and potential losses of self-liquidation of one or more holdings, the risk of a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages, changes in neighborhood values and appeal to purchasers, the possibility of failing to maintain exemptions from registration under the 1940 Act, failure to satisfy the requirements of the Internal Revenue Code of 1986 for maintaining REIT status and, in many cases, relatively small market capitalization, which may result in less market liquidity and greater price volatility for a REIT’s shares. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities.

SENIOR LOAN RISK. Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by the assets of the borrower. The senior loan market has seen a significant increase in loans with limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan credit agreement and general weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions, all of which may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may be unable to declare a default if financial performance deteriorates. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. Although senior loans are generally secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by equity interests in the borrower or its subsidiaries, such equity interest may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss. Senior loans made in connection with highly leveraged transactions are subject to greater risks than other senior loans. For example, the risks of default or bankruptcy of the borrower or the risks that other creditors of the borrower may seek to nullify or subordinate the Fund’s claims on any collateral securing the loan are greater in highly leveraged transactions.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

SMALLER COMPANIES RISK. The stock price of small and/or mid capitalization companies may be more volatile than those of larger companies and therefore the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large capitalization companies. Stock prices of small and/or mid capitalization companies are also generally more vulnerable than those of large capitalization companies to adverse business and economic developments. Securities of small and/or mid capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small and/or mid capitalization companies are typically less financially stable than larger, more established companies and may reinvest a high proportion of their earnings in their business and may not pay dividends. Small and/or mid capitalization companies may also depend on a small number of essential personnel who may also be less experienced than the management of larger companies, making these companies more vulnerable to experiencing adverse effects due to the loss or inexperience of personnel. Small and/or mid capitalization companies also normally have less diverse product lines than those of large capitalization companies and are more susceptible to adverse developments concerning their products.

of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Debt securities are commonly valued by third-party pricing services that utilize a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such securities, cash flows and transactions for comparable instruments. However, because the available information is less reliable and more subjective, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund.

Non-Principal Risks

COMMODITY PRICING RISK. MLPs, MLP-related entities and energy companies may be directly affected by energy commodity prices, especially those energy companies who own the underlying energy commodity. Commodity prices fluctuate for several reasons including, changes in market and economic conditions, the impact of weather on demand, levels of domestic production and imported commodities, energy conservation, domestic and foreign governmental regulation and taxation and the availability of local, intrastate and interstate transportation systems. Volatility of commodity prices which leads to a reduction in production or supply may also impact the performance of MLPs, MLP-related entities and energy companies that are solely involved in the transportation, processing, storing, distribution or marketing of commodities. Volatility of commodity prices may also make it more difficult for MLPs, MLP-related entities and energy companies to raise capital to the extent the market perceives that their performance may be directly tied to commodity prices.

by tax deductions. The Fund will recognize income with respect to that portion of a distribution that is not offset by tax deductions, with the remaining portion of the distribution being treated as a tax-deferred return of capital. The percentage of an MLP’s distribution which is offset by tax deductions will fluctuate over time for various reasons. A significant slowdown in acquisition or investment activity by MLPs held in the Fund’s portfolio could result in a reduction of accelerated depreciation or other deductions generated by these activities, which may result in increased net income to the Fund. A reduction in the percentage of the income from an MLP offset by tax deductions or gains as a result of the sale of portfolio securities will reduce that portion, if any, of the Fund’s distribution treated as a tax-deferred return of capital and increase that portion treated as dividend income, resulting in lower after-tax distributions to the Fund’s shareholders. The Fund will rely to some extent on information provided by MLPs, which is usually not timely, to determine the tax character of the distributions to shareholders.

DEPENDENCE ON KEY PERSONNEL RISK. The Advisor is dependent upon the experience and expertise of the portfolio managers comprising the Management Teams in providing advisory services with respect to the Fund’s investments. If the Advisor were to lose the services of any of these portfolio managers, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for any of the portfolio managers in the event of their death, resignation, retirement or inability to act on behalf of the Advisor.

FAILURE TO QUALIFY AS A REGULATED INVESTMENT COMPANY RISK. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. In such circumstances, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment. If the Fund fails to qualify as a regulated investment company, distributions to the Fund’s shareholders generally would be eligible (i) for treatment of qualified dividend income in the case of individual shareholders and (ii) for the dividends received deduction in the case of corporate shareholders. See “Federal Tax Matters.”

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund's primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market), resulting in premiums or discounts to the Fund's net asset value that may be greater than those experienced by other ETFs. However, because shares can be created and redeemed in Creation Units at the Fund’s net asset value, it is not expected that large discounts or premiums to the net asset value of the Fund will be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values).

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain securities in which the Fund invests. In addition, litigation regarding any of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Advisor determines to sell such a holding.

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the "Investment Management Agreement"), First Trust manages the investment of a portion of the Fund's assets and oversees each Sub-Advisor’s investment of the remainder of the Fund’s assets and pays each Sub-Advisor for its services as Sub-Advisor. First Trust is paid an annual unitary management fee by the Fund equal to 0.85% of the Fund's average daily net assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

Pursuant to a contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided that, the investment companies are advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Board or (ii) upon the termination of the Fund’s management agreement with First Trust, however, it is expected to remain in place for no less than one year from the date of this prospectus.

A discussion regarding the Board’s approval of the continuation of the Investment Management Agreement and Sub-Advisory Agreements is available in the Fund’s Annual Report to Shareholders for the fiscal year ended October 31, 2020.

How to Buy and Sell Shares

purchase or sell shares in smaller “odd lots,” at no per-share price differential. When buying or selling shares through a broker, investors should expect to pay brokerage commissions, investors may receive less than the net asset value of the shares because shares are bought and sold at market prices rather than at net asset value, and investors may pay some or all of the bid-ask spread for each transaction (purchase or sale) of Fund shares. Share prices are reported in dollars and cents per share.

Share Trading Prices

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. As may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate; however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

If you are an individual, the maximum marginal stated federal tax rate for net capital gain is generally 20% (15% or 0% for taxpayers with taxable income below certain thresholds). Some capital gains, including some portion of your capital gain dividends may be taxed at a higher maximum stated tax rate. Some portion of your capital gain dividends may be attributable to the Fund’s interest in a master limited partnership which may be subject to a maximum marginal stated federal tax rate of 28%, rather than the rates set forth above. In the case of capital gain dividends, the determination of which portion of the capital gain dividend, if any, is subject to the 28% tax rate, will be made based on rules prescribed by the United States Treasury. Capital gains may also be subject to the Medicare tax described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

Mortgage-related investments will generally be valued by using a third-party pricing service. If a pricing service does not cover a particular mortgage-related investment, or discontinues covering a mortgage-related investment, the security will be priced using a broker quote. To derive values, pricing services and broker-dealers may use matrix pricing and valuation models, as well as recent market transactions for the same or similar assets. Occasionally, the Advisor’s pricing committee (the “Pricing Committee”) may determine that a pricing service price does not represent an accurate value of a mortgage- related investment, based on the broker quote it receives, a recent trade in the security by the Fund, information from a portfolio manager, or other market information. In the event that the Pricing Committee determines that the pricing service price is unreliable or inaccurate based on such other information, the broker quote may be used. Additionally, if the Pricing Committee determines that the price of a mortgage-related investment obtained from a pricing service and the available broker quote is unreliable or inaccurate due to market conditions or other reasons, or if a pricing service price or broker quote is unavailable, the security will be valued using fair value pricing, as described below.

but before the calculation of the Fund’s net asset value or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from the current market valuations. See the Fund’s SAI for details.

Total Return Information

The table below compares the total return of the Fund to two broad-based security market indices and to the Fund's benchmark index. The information presented for the Fund is for the period indicated.

“Average annual total returns” represent the average annual change in the value of an investment over the period indicated. “Cumulative total returns” represent the total change in value of an investment over the period indicated. The return information shown under “Annual Total Return” in the Fund’s summary prospectus represents the average annual total returns of the Fund as of the calendar year end, while the information presented below is as of the Fund’s fiscal year end. The net asset value per share of the Fund is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The net asset value return is based on the net asset value per share of the Fund and the market return is based on the market price per share of the Fund. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund's NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund's NAV was calculated. Since the shares of the Fund typically do not trade in the secondary market until several days after the Fund's inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the net asset value of the Fund is used as a proxy for the secondary market trading price to calculate market returns. Market and net asset value returns assume that all distributions have been reinvested in the Fund at Market Price and net asset value, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns reflect the reinvestment of dividends on securities in the indices. The returns shown in the table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of shares of the Fund. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future results.

Financial Highlights

The financial highlights table is intended to help you understand the Fund's financial performance for the periods shown. Certain information reflects financial results for a single share of the Fund. The total returns represent the rate that an investor would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). The information for the periods indicated has been derived from financial statements audited by Deloitte & Touche LLP, whose report, along with the Fund's financial statements, is included in the Fund's Annual Report to Shareholders dated October 31, 2020 and is incorporated by reference in the Fund's SAI, which is available upon request.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets (including investment borrowings) in high yield debt securities that are rated below investment grade at the time of purchase or unrated securities deemed by the Fund’s advisor to be of comparable quality. Below investment grade securities are those that, at the time of purchase, are rated lower than “BBB–” by Standard & Poor’s Ratings Group, a division of the McGraw Hill Companies, Inc. (“S&P”), or lower than “Baa3” by Moody’s Investors Service, Inc. (“Moody’s”), or comparably rated by another nationally recognized statistical rating organization (“NRSRO”). High yield debt securities that are rated below investment grade are commonly referred to as “junk” debt. Such securities may include U.S. and non-U.S. corporate debt obligations, bank loans and convertible bonds. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered.

The Fund may invest up to 10% of its net assets (including investment borrowings) in non-U.S. securities denominated in non-U.S. currencies. The Fund may invest in non-income producing securities including Distressed Securities (as defined below) and common stocks. Companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations or financial restructurings are referred to herein as “Distressed Securities.” The Fund invests no

more than 15% of its net assets in Distressed Securities, as determined at the time of the investment. The Fund may receive equity, warrants, corporate bonds and other such securities (i) in conjunction with the restructuring or reorganization, as applicable, of an issuer or any debt issued by an issuer, whether accomplished within or outside of a bankruptcy proceeding (or any other similar statutory restructuring or reorganization proceeding) or (ii) together with (e.g., as part of a unit or package that includes) one or more high yield debt securities (or other debt instruments) of an issuer. The Fund may also invest in investment grade corporate debt obligations and government securities to manage overall credit and duration risk. The Fund does not have any portfolio maturity limitation and may invest its assets in securities with short-term, medium-term or long-term maturities.

The Fund may, under normal market conditions, invest up to 40% of its net assets (including investment borrowings) in bank loans; however the Fund will invest no more than 15% of its net assets (including investment borrowings) in loans other than first lien senior secured floating rate bank loans.

The Fund may invest in listed and over-the-counter derivatives to the extent permitted by the listing rules of the Exchange. Derivatives with comparable economic characteristics to high yield debt securities may be used to satisfy the Fund’s stated policy to invest at least 80% of its net assets (including investment borrowings) in high yield debt securities.

As part of its investment strategy, the Fund intends to maintain both long and short positions in securities under normal market conditions. The Fund takes long positions in securities that the investment advisor believes in the aggregate to have the potential to outperform the Fund’s benchmark, the ICE BofA US High Yield Constrained Index (the “Index”). The Fund takes short positions in securities that the investment advisor believes will decline or in the aggregate will underperform the Index. The Fund’s long positions may total up to 130% of the Fund’s net assets. The Fund’s short positions will range between 0% and 30% of the Fund’s net assets. Under normal market conditions, the Fund takes short positions in U.S. Treasury securities and/or corporate debt obligations, which may be rated investment grade or rated or deemed to be high yield securities.

Short sales are transactions in which the Fund sells a security or other instrument (such as an option, forward, futures or other derivative contract) that it does not own. Short selling allows the Fund to profit from a decline in market price to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. The proceeds received from the Fund’s short sales of securities will generally be used to purchase all or a portion of the Fund’s additional long positions in securities, particularly high yield debt securities. By investing the proceeds received from selling securities short, the Fund could be deemed to be employing a form of leverage, which creates special risks. The use of leverage may increase the Fund’s exposure to long securities positions and make any change in the Fund’s net asset value greater than it would be without the use of leverage, which could result in increased volatility of returns. There is no guarantee that any leveraging strategy the Fund employs will be successful during any period in which it is employed.

The Fund’s investment advisor combines a fundamental credit selection process with relative value analysis and top-down macroeconomic perspectives when selecting investment opportunities. The Fund’s investment advisor believes that an evolving investment environment offers varying degrees of investment risk opportunities in the high yield, bank loan and other fixed income instrument markets. To capitalize on attractive investments and effectively manage potential risk, the Fund’s investment advisor believes that the combination of thorough and continuous credit analysis, market evaluation, diversification and the ability to reallocate investments is critical to achieving higher risk-adjusted returns.

Principal Risks

interest rate. The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. The Fund would then be forced to invest the proceeds at lower interest rates, likely resulting in a decline in the Fund’s income.

DEFAULTED SECURITIES RISK. Defaulted securities pose a greater risk that principal will not be repaid than non-defaulted securities. The reorganization or liquidation of an issuer of a defaulted security may result in the Fund losing its entire investment or being required to accept cash or securities with a value less than its original investment. It may also be difficult to obtain complete and accurate information regarding the true financial condition of the issuer of a defaulted security. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

LEVERAGE RISK. Leverage may result in losses that exceed the amount originally invested and may accelerate the rates of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the value of the Fund’s shares to be volatile and sensitive to market swings.

discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Additional Information on the Fund's Investment Objectives and Strategies

The Fund has adopted a non-fundamental name policy pursuant to Rule 35d-1 under the 1940 Act, whereby the Fund, under normal market conditions, invests at least 80% of its net assets (including investment borrowings) in high yield debt securities that are rated below investment grade at the time of purchase or unrated securities deemed by the Advisor to be of comparable quality. The Name Policy may be changed by the Board without shareholder approval upon 60 days’ prior written notice.

Additional Information on the Fund’s Strategy

The Fund’s investments in high yield debt securities may include senior and subordinated corporate debt obligations and senior floating rate loans, debtor-in-possession (DIP) loans and other junior or bridge loans. The Fund’s investments may also include loan interests that are not secured by any specific collateral of the borrower, loan interests that have a lower than first lien priority on collateral of the borrower, loans to foreign borrowers, loans in foreign currencies and other loans with characteristics that the Advisor believes qualify as bank loans. The Fund may also invest up to 15% of its net assets in illiquid securities. The Fund may receive equity, warrants, corporate bonds and other such securities as a result of the restructuring of the debt of an issuer, or a reorganization of a bank loan or bond, or as part of a package of securities acquired together with a high yield bond or bank loan(s) of an issuer. The Fund may sell securities for a variety of reasons, including, without limitation, to take advantage of a profit on a security, to mitigate risk and to meet redemptions.

The Fund under normal market conditions, invests at least 80% of its net assets (including investment borrowings) in high yield debt securities that are rated below investment grade at the time of purchase or unrated securities deemed by the Advisor to be of comparable quality.

High yield debt securities that are rated below investment grade are commonly referred to as “junk” debt. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. The Fund’s long positions may total up to 130% of the Fund’s net assets. The Fund will take short positions in securities that the Advisor believes will decline or in the aggregate will underperform the Index. These securities may consist of securities included in the Index or other securities, including U.S. Treasury securities, that the Advisor believes will decline or in the aggregate will underperform the Index. The Fund’s short positions will range between 0% and 30% of the Fund’s net assets.

Fund Investments

Principal Investments

Bank Loans

The Fund may invest up to 40% of its net assets (including investment borrowings) in bank loans; however the Fund invests no more than 15% of its net assets (including investment borrowings) in junior loans, and all other bank loans in which the Fund invests are Senior Loans. However, this 40% limit does not apply to investment companies purchased by the Fund that invest principally in bank loans. At least 75% of the Fund’s net assets that are invested in bank loans would be invested in tranches that have a minimum principal amount outstanding of $100 million or more with respect to U.S. borrowers and $200 million or more with respect to non-U.S. borrowers. The Fund may invest in such loans by purchasing assignments on all or a portion of loans or loan participations from third parties. These loans are made by or issued to corporations primarily to finance acquisitions, refinance existing debt, support organic growth, or pay out dividends, and are typically originated by large banks and then syndicated out to institutional investors as well as to other banks. Bank loans typically bear interest at a floating rate although some loans pay a fixed rate. Due to their subordination in the borrower’s capital structure, unsecured and/or subordinated loans involve a higher degree of overall risk than senior bank loans of the same borrower. Unfunded contracts are commitments by lenders (such as the Fund) to loan an amount in the future or that is due to be contractually funded in the future.

Senior floating rate loans are made to companies whose debt is rated below investment grade. Senior floating rate loans typically hold or share a first lien priority and pay interest at rates which are determined periodically on the basis of a floating base lending rate, primarily the London Interbank Offered Rate (“LIBOR”), plus a premium. Senior floating rate loans are typically made to U.S. and, to a lesser extent, non-U.S. corporations, partnerships and other business entities which operate in various industries and geographical regions. Borrowers may obtain these loans to, among other reasons, refinance existing debt and for acquisitions, dividends, leveraged buyouts, and general corporate purposes.

Senior floating rate loans typically are rated below investment grade. Below investment grade securities often are regarded as having predominately speculative characteristics with respect to an issuer’s capacity to pay interest and repay principal. Although many of the Fund’s investments may consist of securities rated below investment grade, the Fund reserves the right to invest in debt securities, including senior floating rate loans, of any credit quality, maturity and duration.

The senior loan market has seen a significant increase in loans with few or none of the financial maintenance covenants (i.e., “covenant-lite loans”) that have traditionally protected lenders including more aggressive terms that favor borrowers with respect to restrictions regarding additional debt, payment terms, income requirements and asset dispositions. A substantial amount of the senior loans held by the Fund are expected to be covenant-lite loans, meaning the Fund may be unable to declare an event of default if financial performance deteriorates, renegotiate the terms of the loan based upon the elevated risk levels or take other actions to help mitigate losses.

Corporate Debt Securities

The Fund may invest corporate debt securities issued by U.S. and non-U.S. companies of all kinds, including those with small, mid and large capitalizations. Corporate debt securities are fixed income securities issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary differences being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. Such debt instruments are typically issued by corporations, generally in the form of interest-bearing notes, or by an affiliated business trust of a corporation, generally in the form of (i) beneficial interests in subordinated debentures or similarly structured securities or (ii) more senior debt securities that pay income and trade in a manner similar to preferred securities. Corporate debt may be rated investment grade or below investment grade and may carry fixed or floating rates of interest.

Derivatives

The Fund may invest up to 30% of its net assets (including investment borrowings) in derivative instruments to allow the Fund to seek to enhance return, to hedge some of the risks of its investments in securities, as a substitute for a position in an underlying asset, to reduce transaction costs, to maintain full market exposure (which means to adjust the characteristics of its investments to more closely approximate those of the markets in which it invests), to manage cash flows, to preserve capital or to manage its foreign currency exposures.

High Yield Debt

Non-U.S. Debt Securities

Non-Principal Investments

Cash Equivalents and Short-Term Investments

Normally, the Fund invests substantially all of its assets to meet its investment objectives. The Fund may invest the remainder of its assets in securities with maturities of less than one year or cash equivalents, or each may hold cash. The percentage of the Fund invested in such holdings varies and depends on several factors, including market conditions. For temporary defensive purposes and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities, or it may hold cash. During such periods, the Fund may not be able to achieve its investment objectives. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the Fund's SAI.

Convertible Bonds

Illiquid Securities

The Fund may invest up to 15% of its net assets in securities and other instruments that are, at the time of investment, illiquid (determined using the Securities and Exchange Commission's standard applicable to investment companies, i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For this purpose, illiquid securities may include, but are not limited to, certain restricted securities (securities the disposition of which is restricted under the federal securities laws), certain securities that may only be resold pursuant to Rule 144A under the Securities Act, that are deemed to be illiquid, and certain repurchase agreements.

Investment Companies and Other Pooled Investment Vehicles

The Fund may invest in securities of other investment companies, including other exchange-traded funds (“ETFs”). As a shareholder in a pooled investment vehicle, the Fund bears its ratable share of that vehicle's expenses and would remain subject to payment of the Fund's management fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other pooled investment vehicles. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed-end investment companies. Securities of other pooled investment vehicles may be leveraged, in which case the value and/or yield of such securities will tend to be more volatile

than securities of unleveraged vehicles. The Fund may satisfy the Name Policy by investing in investment companies and other pooled investment vehicles that are subject to a comparable name policy and invest in the types of securities in which the Fund may invest directly.

Mortgage-Backed Securities

Although not a part of the Fund’s principal investment strategy, the Fund may invest in mortgage-backed securities, which represent direct or indirect participations in, or are secured by and payable from, mortgage loans secured by real property and can include single- and multi-class pass-through securities and collateralized mortgage obligations. Mortgage-backed securities are based on different types of mortgages, including those on commercial real estate or residential properties. These securities often have stated maturities of up to thirty years when they are issued, depending upon the length of the mortgages underlying the securities. The Fund may also invest in U.S. agency mortgage-backed securities and collateralized mortgage securities issued by the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”).

Preferred Securities

While some preferred securities are issued with a final maturity date, others are perpetual in nature. In certain instances, a final maturity date may be extended and/or the final payment of principal may be deferred at the issuer’s option for a specified time without any adverse consequence to the issuer. No redemption can typically take place unless all cumulative payment obligations to preferred security investors have been met, although issuers may be able to engage in open-market repurchases without regard to any cumulative dividends or interest payable. A portion of the portfolio may include investments in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to holders of such securities. Should an issuer default on its obligations under such a security, the amount of income earned by the Fund may be adversely affected.

Preferred securities may be issued by trusts or other special purpose entities established by operating companies, and therefore may not be direct obligations of operating companies. At the time a trust or special purpose entity sells its preferred securities to investors, the trust or special purpose entity generally purchases debt of the operating company (with terms comparable to those of the trust or special purpose entity securities). The trust or special purpose entity, as the holder of the operating company’s debt, has priority with respect to the operating company’s earnings and profits over the operating company’s common shareholders, but is typically subordinated to other classes of the operating company’s debt. Typically a preferred share has a rating that is below that of its corresponding operating company’s senior debt securities due to its subordinated nature.

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objectives. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CALL RISK. Some debt securities may be redeemed at the option of the issuer, or “called,” before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. The Fund would then be forced to invest the unanticipated proceeds at lower interest rates, likely resulting in a decline in the Fund’s income. Such redemptions and subsequent reinvestments would also increase a Fund’s portfolio turnover. If a called debt security was purchased by a Fund at a premium, the value of the premium may be lost in the event of a redemption.

CASH TRANSACTIONS RISK. The Fund will effect some or all of its creations and redemptions for cash rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only in-kind. ETFs are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. A Fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the Fund will generally cause the Fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund’s shares than for ETFs that distribute portfolio securities in-kind.

interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

FLOATING RATE DEBT INSTRUMENTS RISK. Investments in floating rate debt instruments are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. The Fund may invest in floating rate loans considered to be high yield, or “junk,” instruments and considered speculative because of the credit risk of their issuers. Such issuers are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund. An economic downturn would also generally lead to a higher non-payment rate, and a floating rate debt instrument may lose significant market value before a default occurs. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to Fund, and that the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, there is no central clearinghouse for loan trades and the loan market has not established enforceable settlement standards or remedies for failure to settle. As such, the secondary market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods which may cause the Fund to be unable to realize the full value of its investment. Lastly, floating rate loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws.

LEVERAGE RISK. The Fund has exposure to instruments subjecting them to leverage risk. Leverage may result in losses that exceed the amount originally invested and may accelerate the rates of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the value of the Fund’s portfolio and the Fund’s shares to be volatile and sensitive to market swings. Certain instruments have the potential for unlimited loss, regardless of the size of the initial investment.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

or inadequate processes and technology or systems failures. Although the Fund and the Advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SENIOR LOAN RISK. Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by the assets of the borrower. The senior loan market has seen a significant increase in loans with limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan credit agreement and general weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions, all of which may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may be unable to declare a default if financial performance deteriorates. This may hinder the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

SHORT SALES RISK. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. The risk of loss on a shorted position arises from the increase in value of the security sold short and is potentially unlimited unlike the risk of loss on a long position, which is limited to the amount paid for the investment plus transaction costs. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, in times of unusual or adverse economic, market or political conditions, the Fund may not be able to fully or partially implement its short selling strategy. In addition, as a series of an investment company registered under the 1940 Act, the Fund must segregate liquid assets, or engage in other measures to “cover” open positions with respect to short sales. The Fund may nonetheless incur significant losses on short sales even if they are covered.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

Non-Principal Risks

with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Issuers in Asia may not be subject to the same accounting, auditing and financial reporting standards as U.S. companies and if their securities are not listed on a U.S. exchange, they may not be subject to the same corporate governance standards as U.S. issuers. In addition, satisfactory custodial services for investment securities may not be available in some Asia countries, which may result in the Fund incurring additional costs and delays in providing transportation and custody services for such securities outside such countries. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund.

to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. Changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. An increase in the strength of the U.S. dollar relative to other currencies may cause the value of the Fund to decline. Certain non-U.S. currencies may be particularly volatile, and non-U.S. governments may intervene in the currency markets, causing a decline in value or liquidity in the Fund's non-U.S. holdings whose value is tied to the affected non-U.S. currency. Additionally, the prices of non-U.S. securities that are traded in U.S. dollars are often indirectly influenced by currency fluctuations.

DISTRESSED SECURITIES RISK. The Fund may invest in distressed debt securities. Distressed securities are speculative and involve substantial risks in addition to the risks of investing in high-yield debt securities that are not in default. In some instances, the Fund will not receive interest payments from the distressed securities it holds and may incur additional expenses to protect its investment. These securities may present a substantial risk of default and there is a substantial risk that the principal will not be repaid. A Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or of interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in exchange for such securities may be subject to restrictions on resale.

risk of expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries. Enforcing legal rights may be made difficult, costly and slow in emerging markets as there may be additional problems enforcing claims against non-U.S. governments.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests.Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

INVESTMENT COMPANIES RISK. If the Fund invests in investment companies, Fund shareholders bear both their proportionate share of Fund expenses and, indirectly, the expenses of the investment companies. Also, the investment companies are subject to the risks of the underlying securities that they hold. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed-end investment companies. Closed-end investment companies may be leveraged, in which case the value and/or yield of their shares will tend to be more volatile than shares of unleveraged funds. In addition, for index-based ETFs, the performance of an ETF may diverge from the performance of such index (commonly known as tracking error). Moreover, shares of closed-end investment companies and ETFs may be sold at a discount from their net asset value.

government overspending and political instability. International economic conditions, particularly those in the United States, Europe and Asia, as well as world prices for oil and other commodities may also influence the development of Latin American economies. Many Latin American countries are highly reliant on the exportation of commodities and their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities. In the past, certain Latin American economies have been influenced by changing supply and demand for a particular currency, monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries), and currency devaluations and revaluations. Other Latin American investment risks may include inadequate investor protection, less developed regulatory, accounting, auditing and financial standards, unfavorable changes in laws or regulations, natural disasters, corruption and military activity. The governments of many Latin American countries may also exercise substantial influence over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Securities of companies in Latin America may also be subject to significant price volatility.

SWAP AGREEMENTS RISK. The Fund may enter in swap agreements. Swap agreements are two-party contracts entered into for a set period of time in which the parties agree to exchange payments based on some underlying reference or asset (such as interest rates). The use of swaps is a highly specialized activity that involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. These transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Fund’s direct investments in the reference assets. Transactions in swaps can involve greater risks than if the Fund had invested directly in the reference asset since, in addition to general market risks, swaps may be leveraged and are also subject to credit risk, counterparty risk, liquidity risk and valuation risk. Because they are two-party contracts and may have terms of greater than seven days, certain swap transactions may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap counterparty. Some swaps may be complex and difficult to value. Swaps may also be subject to pricing or “basis” risk, which exists when a particular swap becomes extraordinarily expensive relative to historical prices or the price of corresponding cash market instruments. Under certain market conditions it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. The prices of swaps can be very volatile, and a variance in the degree of volatility or in the direction of the price of the reference asset from the sub-adviser’s expectations may produce significant losses in the Fund’s investments in swaps. In addition, a perfect correlation between a swap and an investment position may be impossible to achieve. As a result, the Fund’s use of swaps may not be effective in fulfilling the Fund’s investment strategies and may contribute to losses that would not have been incurred otherwise. Certain swaps are not bilateral agreements but are centrally-cleared and are exchange-traded. Central clearing tends to decrease credit risk and improve liquidity but many regulations regarding centrally-cleared swaps have not been fully implemented and the scope of the risks remain unclear. As central clearing does not make the agreements risk-free and there is no guarantee that the Fund would consider all centrally-cleared or exchange-traded swaps to be liquid.

Fund Organization

Management of the Fund

William Housey, Jeffrey Scott and Orlando Purpura are the Fund’s portfolio managers and share responsibilities for the day-to-day management of the Fund’s investment portfolio.

•

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the "Investment Management Agreement"), First Trust manages the investment of the Fund's assets. First Trust is paid an annual unitary management fee by the Fund equal to 0.95% of the Fund’s average daily net assets and is responsible for the expenses of the Fund including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, expenses associated with short sales transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

How to Buy and Sell Shares

For purposes of the 1940 Act, the Fund is treated as a registered investment company, and, absent an available exemption or exemptive relief, the acquisition of shares by other registered investment companies and companies relying on Sections 3(c)(1) and 3(c)(7) of the 1940 Act is subject to the restrictions of Section 12(d)(1) of the 1940 Act. The Trust, on behalf of the Fund, has received an exemptive order from the Securities and Exchange Commission that permits certain registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions, including that any such investment companies enter into an agreement with the Fund regarding the terms of any investment.

Share Trading Prices

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold or redeemed, even if you sell or redeem the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

The Fund’s net asset value is determined as of the close of trading (normally 4:00 p.m., Eastern time) on each day the New York Stock Exchange is open for business. Net asset value is calculated for the Fund by taking the market price of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing such amount by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share. All valuations are subject to review by the Board or its delegate.

The Fund’s investments are valued daily in accordance with valuation procedures adopted by the Board, and in accordance with provisions of the 1940 Act. Certain securities in which the Fund may invest are not listed on any securities exchange or board of trade. Such securities are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market makers exist. Certain securities, particularly debt securities, have few or no trades, or trade infrequently, and information regarding a specific security may not be widely available or may be incomplete. Accordingly, determinations of the fair value of debt securities may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. Typically, debt securities are valued using information provided by a third-party pricing service. The third- party pricing service primarily uses broker quotes to value the securities.

The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value in accordance with valuation procedures adopted by the Board and in accordance with the 1940 Act. Portfolio securities listed on any exchange other than Nasdaq and the London Stock Exchange Alternative Investment Market (“AIM”) are valued at the last sale price on the business day as of which such value is being determined. Securities listed on Nasdaq or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

Senior Loans in which the Fund invests are not listed on any securities exchange or board of trade. Senior Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may

play a greater role in valuation of Senior Loans than for other types of securities. Typically, Senior Loans are fair valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board or its delegate, the Advisor’s Pricing Committee, at fair value. The use of fair value pricing by the Fund is governed by valuation procedures adopted by the Board and in accordance with the provisions of the 1940 Act. These securities generally include, but are not limited to, certain restricted securities (securities which may not be publicly sold without registration under the Securities Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s net asset value or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from the current market valuations. See the Fund’s SAI for details.

Because foreign securities exchanges may be open on different days than the days during which an investor may purchase or sell shares of the Fund, the value of the Fund’s securities may change on days when investors are not able to purchase or sell shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Total Return Information

The table below compares the total return of the Fund to the Fund's benchmark index. The information presented for the Fund is for the period indicated.

In managing the Fund’s portfolio, the Fund’s portfolio managers utilize a top-down, bottom-up analytical investment process. The portfolio managers will first conduct a top-down review of the mortgage-backed security and Treasury fixed income sectors to determine sector position weights based on its evaluation of market fundamentals. The portfolio managers then perform a bottom-up analysis of individual securities to determine in which sub-sectors the portfolio will be over, neutral and underweight. The portfolio managers analyze the Fund’s holdings on a systematic basis to monitor any changes in security and portfolio performance, in addition to looking for meaningful changes in risk factors.

Under normal market conditions, the portfolio managers will manage the Fund’s portfolio to have a weighted average effective duration of eight or more years. Duration is a mathematical calculation of the average life of a debt security (or portfolio of debt securities) that serves as a measure of its price risk. In general, each year of duration represents an expected 1% change in the value of a security for every 1% immediate change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. The Fund’s portfolio managers will calculate the duration of the portfolio by modeling the cash flows of all the individual holdings, including the impact of prepayment variability and coupon adjustments where applicable, to determine the duration of each holding and then aggregating based on the size of the position. In performing this duration calculation, the Fund’s portfolio managers will utilize third-party models.

The Fund’s investments in mortgage-related securities may include investments in fixed or adjustable-rate securities structured as “pass-through” securities and collateralized mortgage obligations, including residential and commercial mortgage-backed securities, stripped mortgage-backed securities and real estate mortgage investment conduits. The Fund will invest in mortgage-related securities issued or guaranteed by the U.S. government, its agencies (such as Ginnie Mae), and U.S. government-sponsored entities (such as Fannie Mae and Freddie Mac). The Fund may purchase government-sponsored mortgage-related securities in TBA Transactions, including mortgage dollar rolls. In a TBA Transaction, a seller and buyer of securities agree upon a price for delivering a given volume of securities at a specified future date. The characteristic feature of a TBA Transaction is that the actual identity of the securities to be delivered at settlement is not specified on the trade date. Instead, participants agree upon only the general parameters of the securities to be delivered, including issuer, maturity, coupon, price, par amount and settlement date. Generally, two days prior to the settlement date, the seller provides the buyer with the identity of the securities it intends to deliver on the settlement date. In a mortgage dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Fund’s portfolio managers.

In addition to its investment in securities issued or guaranteed by the U.S. government, its agencies and government-sponsored entities, the Fund may invest up to 20% of its net assets in other types of debt securities, including privately-issued, non-agency sponsored asset-backed and mortgage-related securities, futures contracts, options, swap agreements, cash and cash equivalents, and ETFs that investment principally in fixed income securities. Further, the Fund may enter into short sales as part of its overall portfolio management strategy, or to offset a potential decline in the value of a security; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets. To the extent required under applicable federal securities laws, rules, and interpretations thereof, the Fund will “set aside” liquid assets or engage in other measures to “cover” open positions and short positions held in connection with the foregoing types of transactions.

Although the Fund intends to invest primarily in investment grade securities, the Fund may invest up to 20% of its net assets in securities of any credit quality, including securities that are below investment grade, which are also known as high yield securities, or commonly referred to as “junk” bonds, or unrated securities that have not been judged by the portfolio managers to be of comparable quality to rated investment grade securities. In the case of a split rating between one or more of the nationally recognized statistical rating organizations, the Fund will consider the highest rating.

The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).

Principal Risks

the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

LEVERAGE RISK. The Fund has exposure to instruments subjecting them to leverage risk. Leverage may result in losses that exceed the amount originally invested and may accelerate the rates of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the value of the Fund’s shares to be volatile and sensitive to market swings.

Fund's actual yield to maturity on any mortgage-related securities. Along with prepayment risk, mortgage-related securities are significantly affected by interest rate risk.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

volatility. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction.

Additional Information on the Fund's Investment Objectives and Strategies

The Fund is a series of First Trust Exchange-Traded Fund IV and is regulated as an “investment company” under the 1940 Act. The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objective is fundamental and may not be changed without approval by the holders of a majority of the outstanding voting securities of the Fund. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”), without shareholder approval. If there is a material change to the Fund’s principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.

Additional Information on the Fund’s Strategy

The Fund targets an estimated weighted average effective duration of eight years or more. In comparison to maturity (i.e., the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the expected price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments and other factors. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments, call features and coupon adjustments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with lower durations tend to be less sensitive to interest rate changes than securities with higher durations. In general, a portfolio of securities with a lower duration can be expected to be less sensitive to interest rate changes than a portfolio with a higher duration.

Fund Investments

Principal Investments

Asset-Backed Securities

Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Asset-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities.

Debt Securities

Derivative Instruments

The Fund may invest in options, futures and swaps. The use of these derivative transactions may allow the Fund to obtain net long or short exposures to selected interest rates or durations. The Fund may also utilize derivatives to enhance return, to hedge some of the risks of its investments in securities, as a substitute for a position in the underlying asset, to reduce transaction costs, to maintain full market exposure (which means to adjust the characteristics of its investments to more closely approximate those of the markets in which it invests), to manage cash flows or to preserve capital.

Exchange-Traded Funds

ETFs trade on a securities exchange and their shares may, at times, trade at a premium or discount to their net asset value. As a stockholder in an investment company or other pooled vehicle, the Fund will bear its ratable share of that investment

company’s or vehicle’s expenses and would remain subject to payment of the Fund’s or vehicle’s advisory and administrative fees with respect to assets so invested.

High Yield Securities

The Fund may invest in securities of any credit quality, including securities that are rated below investment grade. Below investment grade securities are rated below “BBB-” by Standard & Poor’s Ratings Group, a division of The McGraw-Hill Companies (“S&P”), or Fitch Ratings, Inc. (“Fitch”), below “Baa3” by Moody’s Investors Service, Inc. (“Moody’s”) or comparably rated by another NRSRO or, if unrated, determined by the Sub‑Advisor to be of comparable credit quality at the time of purchase. Below investment grade securities are commonly referred to as “junk” or “high yield” securities and are considered speculative with respect to the issuer’s capacity to pay interest and repay principal.

Mortgage-Related Investments

Mortgage-related securities are structured debt obligations collateralized by pools of residential or commercial mortgage loans made by banks and other financial institutions to finance purchases of residential homes, commercial buildings and other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors by various governmental and private organizations and provide the holder with monthly payments derived from the principal and interest payments made by the individual borrowers on the pooled mortgage loans. In their simplest form, mortgage-related securities are structured as “pass-through” securities, meaning they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. In the basic mortgage-pass through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a pool consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans. However, mortgage-related securities may also be structured as collateralized mortgage obligations (“CMOs”). A CMO is a multi-class bond backed by a pool of mortgage pass-through certificates or mortgage loans. While CMOs may be collateralized by whole mortgage loans or private mortgage bonds, they are generally collateralized by portfolios of mortgage pass-through securities guaranteed by Ginnie Mae, Fannie Mae and Freddie Mac, and their income streams. Each class of CMOs, often referred to as a “tranche,” is issued at a specific coupon rate and offers investors various maturity and credit risk characteristics. Tranches are categorized as senior, mezzanine, and subordinated/equity or “first loss,” according to their degree of risk. The most senior tranche has the greatest collateralization and pays the lowest interest rate. If there are defaults or the collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Lower tranches represent lower degrees of credit quality and pay higher interest rates intended to compensate for the increased risks. The return on the lower tranches is especially sensitive to the rate of defaults in the collateral pool. The lowest tranche (i.e., the “equity” or “residual” tranche) specifically receives the residual interest payments (money that is left over after the higher tranches have been paid and expenses of the issuing entities have been paid) rather than a fixed interest rate.

Mortgage-related investments may be issued or guaranteed by the U.S. government, its agencies or instrumentalities, (such as Ginnie Mae), and U.S. government-sponsored entities, (such as Fannie Mae and Freddie Mac). Government agency or instrumentality securities have different levels of credit support. Securities issued by the U.S. governments, its agencies or instrumentalities carry a guarantee as to the timely repayment of principal and interest that is backed by the full faith and credit of the U.S. government. However, the full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. Securities issued by government-sponsored entities may only be backed by the creditworthiness of the issuing institution, not the U.S. government. Government-sponsored entity issuers may have the right to borrow from the U.S. Treasury to meet their obligations.

The Fund may also invest up to 20% of its net assets in privately-issued, non-agency sponsored mortgage- and asset-backed securities. There are no direct or indirect government or agency guarantees of payments in mortgage pools created by non-government issuers.

coupon and maturity) securities on a future date. During the period between a sale and repurchase, the Fund will forgo principal and interest paid on the mortgage-backed securities. The Fund will earn or lose money on a mortgage dollar roll from any difference between the sale price and the future purchase price. In a sale and repurchase, the Fund will also earn money on the interest earned on the cash proceeds of the initial sale. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the portfolio managers.

U.S. Government Securities

The Fund may invest in U.S. government securities. U.S. government securities include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government, or by various instrumentalities which have been established or sponsored by the U.S. government, including STRIPS and zero-coupon bonds. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government. The Fund may also invest in callable agency securities, which give the issuer (the U.S. government agency) the right to redeem the security prior to maturity. The Fund may also invest in U.S. government inflation-indexed securities. At times, the Fund may allocate its investments into direct obligations of the U.S. government (such as Treasury bonds, bills and notes) and in securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities, including government-sponsored entities.

Non-Principal Investments

Cash Equivalents and Short-Term Investments

Under normal market conditions, the Fund may invest up to 20% of its net assets in short-term debt securities that are not publicly-issued U.S. Treasury securities and bonds, debentures and mortgage-backed securities issued or guaranteed by the U.S. government, its agencies or government-sponsored entities, such as money market funds and other cash equivalents, or it may hold cash. The percentage of the Fund invested in these types of holdings will vary and will depend on several factors, including market conditions. Cash earmarked or otherwise held as collateral for settling mortgage dollar rolls and other delayed-delivery transactions is not included within the above 20% limitation and will count towards the Fund's 80% investment requirement.

The Fund may invest in securities with maturities of less than one year or cash equivalents, or it may hold cash, in order to collateralize, its investments or for temporary defensive purposes. The percentage of the Fund invested in these types of holdings varies and depends on several factors, including market conditions. For temporary defensive purposes, during the initial invest-up period and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities or it may hold cash. During such periods, the Fund may not be able to achieve its investment objective. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the Fund’s SAI.

Disclosure of Portfolio Holdings

Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objectives. Before you invest, you should consider the following disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a centralized securities exchange making them generally less liquid and more difficult to value than common stock. The values of debt securities may also increase or decrease as a result of market fluctuations, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets generally.

low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Interest rate risk is generally lower for shorter term investments and higher for longer term investments. Duration is a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of a debt security, the greater the debt security’s price sensitivity is to changes in interest rates. Rising interest rates also may lengthen the duration of debt securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. An increase in interest rates could also cause principal payments on a debt security to be repaid at a slower rate than expected. This risk is particularly prevalent for a callable debt security where an increase in interest rates could cause the issuer of that security to not redeem the security as anticipated on the call date, effectively lengthening the security’s expected maturity, in turn making that security more vulnerable to interest rate risk and reducing its market value. When interest rates fall, the Fund may be required to reinvest the proceeds from the sale, redemption or early prepayment of a debt security at a lower interest rate.

could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

commissions, dealer mark-ups and other costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is more broadly diversified.

remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

U.S. GOVERNMENT SECURITIES RISK. The Fund invest in U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.While securities issued or guaranteed by U.S. federal government agencies (such as Ginnie Mae) are backed by the full faith and credit of the U.S. Department of the Treasury, securities issued by government sponsored entities (such as Fannie Mae and Freddie Mac) are solely the obligation of the issuer and generally do not carry any guarantee from the U.S. government. No assurance can be given that the U.S. government will provide financial support to its government sponsored entities or any other agency if not obligated by law to do so.

Non-Principal Risks

ASSET-BACKED SECURITIES RISK. Asset-backed securities are debt securities typically created by buying and pooling loans or other receivables other than mortgage loans and creating securities backed by those similar type assets. They are typically issued by trusts and special purpose co-purchasers that pass income from the underlying pool to investors. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. Certain asset-backed securities do not have the benefit of the same security interest in the related collateral as do mortgage-backed securities, nor are they provided government guarantees of repayment. Credit card receivables are generally unsecured, and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. In addition, some issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

ETF RISK. The Fund may invest in ETFs. Most ETFs use a “passive” investment strategy and seek to replicate the performance of a market index. Such ETFs do not take defensive positions in volatile or declining markets their shares may trade below net asset value. While some ETFs seek to achieve the same return as a particular market index, the performance of the ETF may diverge from the performance of the index. Some ETFs are actively managed ETFs and do not track a particular index which indirectly subjects an investor to active management risk. An active secondary market in ETF shares may not develop or be maintained and may be halted or interrupted due to actions by its listing exchange, unusual market conditions or other reasons. There can be no assurance that an ETF’s shares will continue to be listed on an active exchange. In addition, shareholders bear both their proportionate share of the Fund’s expenses and, indirectly, the ETF’s expenses, incurred through the Fund’s ownership of the ETF. Because the expenses and costs of an ETF are shared by its investors, redemptions by other investors in the ETF could result in decreased economies of scale and increased operating expenses for such ETF. These transactions might also result in higher brokerage, tax or other costs for the ETF. This risk may be particularly important when one investor owns a substantial portion of the ETF. There is a risk that ETFs in which the Fund invests may terminate due to extraordinary events. For example, any of the service providers to ETFs, such as the trustee or sponsor, may close or otherwise fail to perform their obligations to the ETF, and the ETF may not be able to find a substitute service provider. Also, certain ETFs may be dependent upon licenses to use various indexes as a basis for determining their compositions and/or otherwise to use certain trade names. If these licenses are terminated, the ETFs may also terminate. In addition, an ETF may terminate if its net assets fall below a certain amount.

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain companies in which the Fund invests. In addition, litigation regarding any of the issuers of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the portfolio managers determine to sell such a holding.

under a swap agreement in the event of the default or bankruptcy of a swap counterparty. Some swaps may be complex and difficult to value. Swaps may also be subject to pricing or “basis” risk, which exists when a particular swap becomes extraordinarily expensive relative to historical prices or the price of corresponding cash market instruments. Under certain market conditions it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. The prices of swaps can be very volatile, and a variance in the degree of volatility or in the direction of the price of the reference asset from the sub-adviser’s expectations may produce significant losses in the Fund’s investments in swaps. In addition, a perfect correlation between a swap and an investment position may be impossible to achieve. As a result, the Fund’s use of swaps may not be effective in fulfilling the Fund’s investment strategies and may contribute to losses that would not have been incurred otherwise. Certain swaps are not bilateral agreements but are centrally-cleared and are exchange-traded. Central clearing tends to decrease credit risk and improve liquidity but many regulations regarding centrally-cleared swaps have not been fully implemented and the scope of the risks remain unclear. As central clearing does not make the agreements risk-free and there is no guarantee that the Fund would consider all centrally-cleared or exchange-traded swaps to be liquid.

How to Buy and Sell Shares

Share Trading Prices

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund, or otherwise not in the Fund's best interests.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Investments in Certain Non-U.S. Corporations

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

Net Asset Value

The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value, in accordance with valuation procedures adopted by the Board and in accordance with the 1940 Act. Portfolio securities listed on any exchange other than The Nasdaq Stock Market LLC ("Nasdaq") and the London Stock Exchange Alternative Investment Market (“AIM”) are valued at the last sale price on the business day as of which such value is being determined. Securities listed on Nasdaq or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there has been no sale on such day, or no official closing price in the case of securities traded on Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

that the Pricing Committee determines that the pricing service price is unreliable or inaccurate based on such other information, the broker quote may be used. Additionally, if the Pricing Committee determines that the price of a Mortgage-Related Investment obtained from a pricing service and the available broker quote is unreliable or inaccurate due to market conditions or other reasons, or if a pricing service price or broker quote is unavailable, the security will be valued using fair value pricing, as described below.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in the equity securities of companies identified by the Fund’s investment sub-advisor, Energy Income Partners, LLC (“EIP” or the “Sub-Advisor”), as having or seeking to have a positive carbon impact. The Sub-Advisor defines positive carbon impact companies as companies that reduce, have a publicly available plan to reduce, or enable the reduction of carbon and other greenhouse gas (“GHG”) emissions from the production, transportation, conversion, storage and use of energy. The companies in which the Fund invests will have demonstrated a commitment to positive carbon impact activities, as determined by the Sub-Advisor, based on its fundamental research and review of public documents, such as regulatory filings and investor and public communications. Examples of positive carbon impact activities include investing capital in activities and technologies with lower GHG emissions, such as wind and solar power generation, or by replacing coal fired power generation facilities with natural gas power generation facilities.

In addition, natural gas pipeline companies that supply natural gas power generation facilities have a positive carbon impact by enabling the use of wind and solar power because natural gas power generation facilities serve to back-up and compensate

for the intermittent availability of wind and solar power. Other examples of companies having a positive carbon impact include those making investments to reduce methane leaks from the processing, transport and distribution of natural gas, investments in the capture, transportation and sequestration of carbon dioxide or investments in grid-level battery storage or fuel cells.

The Sub-Advisor conducts the following four-step process when selecting investments for the Fund:

Define a universe of potential investments from companies operating in the following industries, including but not limited to: utilities; natural gas pipelines; manufacturers, contracted developers and/or owners of renewable energy; and other companies that operate and/or provide services in support of activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. These companies may exhibit a higher than average payout ratio supported by stable cash flows derived from long-term contracts, a regulated cost-of-service pricing scheme with inflation adjustments or cost pass-through protections.

Eliminate companies that in the Sub-Advisor’s view have no plans to reduce emissions and have a strategic commitment to any of the following activities that (individually, and not collectively) constitutes more than a de minimis amount of annual enterprise-wide earnings before interests, taxes, depreciation and amortization (“EBITDA”):

coal production;

crude oil exploration and production; or

transportation, storage or delivery of crude oil.

Identify among the remaining companies those that, in the Sub-Advisor’s view, currently or plan to:

reduce carbon and other GHG emissions within their own operations;

facilitate reduction of carbon and other GHG emissions across the broader market, such as through the displacement of more carbon-intensive fuels such as coal or oil; or

facilitate the increased use of renewable resources across the broader market such as by balancing the variable production of wind and solar power with fully available natural gas generated power or through the storage of electricity.

The Sub-Advisor then selects securities for the Fund’s portfolio from the remaining eligible securities based upon its holistic assessment of both quantitative and qualitative attributes associated with the remaining securities. Such quantitative attributes include, but are not limited to, operating metrics and financial metrics, such as stability of cash flows and the strength of the balance sheet. Relevant qualitative attributes include, but are not limited to, the Sub-Advisor’s confidence in the company’s management team, the sustainability of a company’s business model and the competitiveness of a company’s assets. In its assessment of quality, the Sub-Advisor will not consider any measures of valuation. No one quantitative or qualitative attribute is dispositive in the Sub-Advisor’s security selection process, but rather, when considered cumulatively, such attributes help inform the Sub-Advisor’s investment decisions in light of market conditions and the Sub-Advisor’s own experience. In determining security weights, the Sub-Advisor balances each position’s expected rate of return against risks, position size and diversification considerations and the Fund’s portfolio limitations.

The Fund’s investments will be concentrated in the industries constituting the energy infrastructure sector. These companies principally include: utilities; natural gas pipeline companies; manufacturers, contracted developers and/or owners of renewable energy; and other companies that derive the majority of their earnings from manufacturing, operating or providing services in support of infrastructure assets and/or infrastructure activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. The Fund will generally not invest in companies comprising the following industries: coal production, oil exploration and production, or crude oil storage, transportation and delivery. The Fund’s portfolio will be principally composed of equity securities, including common stock, depositary receipts, and units issued by master limited partnerships (“MLPs”). Such securities may be issued by small, mid and large capitalization companies operating in developed market countries. As of January 31, 2021, the Fund had significant investments in energy and utility companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

CONCENTRATION RISK. The Fund is concentrated in the industries comprising the energy infrastructure sector. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A concentration makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is not so concentrated.

ENERGY COMPANIES RISK. The success of energy companies may be cyclical and highly dependent on energy prices. The market value of securities issued by energy companies may decline for many reasons, including, among other things, changes in the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production of energy sources, exchange rates, interest rates, economic conditions, tax treatment, energy conservation efforts, increased competition and technological advances. Energy companies may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of energy companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of energy companies. Energy companies may also operate in, or engage in transactions involving, countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters.

condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

IMPACT INVESTING RISK. The Fund’s investment strategy limits the number of investment opportunities available to the Fund. Only securities issued by companies identified by the Sub-Advisor as seeking to reduce the carbon impact of the production, transportation, conversion or storage of energy are eligible for inclusion in the Fund’s portfolio. As a result, the Fund may underperform other funds that are not subject to such limits. In addition, companies selected for inclusion in the Fund may not ultimately undertake, or be successful in, their efforts to reduce the carbon impact of the production, transportation, conversion or storage of energy.

could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

Additional Information on the Fund's Investment Objective and Strategies

While it is not expected that the Fund will invest in the securities of other investment companies, any such investments would be subject to limitations imposed by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

Additional Information on the Fund’s Strategy

The Sub-Advisor generally seeks to own companies that provide a cost-effective way of transporting, storing and converting the lowest cost energy, which today increasingly means cleaner energy in the form of natural gas and/or renewable electric power. The Sub-Advisor expects the Fund’s portfolio to include securities issued by, for example, utility companies, companies that own or operate natural gas pipelines and contracted developers of renewable energy, energy storage and related technologies. These companies tend to be natural monopolies operating under a cost-of-service model regulated at the federal or state level or companies operating under long-term contracts tied more to a targeted rate of return on capital than to volumes and margins.

Fund Investments

Principal Investments

Equity Securities

The Funds invest in equity securities, including common stocks and depositary receipts.Common stock represents an equity ownership interest in issuers. Holders of common stock are entitled to the income and increase in the value of the assets and business of the issuers after all debt obligations and obligations to preferred stockholders are satisfied. Depositary receipts are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies. Depositary receipts may or may not be jointly sponsored by the underlying issuer.

Master Limited Partnerships

An MLP is a limited partnership or a limited liability company that is treated as a partnership for federal income tax purposes, the interests in which (known as units) are traded on securities exchanges or over-the-counter. MLPs are typically engaged in one or more aspects of the exploration, production, processing, transmission, marketing, storage or delivery of energy-related commodities such as natural gas, natural gas liquids, coal, crude oil or refined petroleum products. Holders of MLP units have limited control and voting rights on matters affecting the partnership. If publicly traded, to be treated as a partnership for U.S. federal income tax purposes, the MLP must receive at least 90% of its income from qualifying sources, including interest, dividends, real estate rents, gain from the sale or disposition of real property, income and gain from mineral or natural resources activities, income and gain from the transportation or storage of certain fuels, gain from the sale or disposition of a capital asset held for the production of income described in the foregoing. Mineral or natural resources activities include exploration, development, production, mining, refining, marketing and transportation (including pipelines), of oil and gas, minerals, geothermal energy, fertilizer, timber or carbon dioxide.

Non-Principal Investments

Cash Equivalents and Short-Term Investments

Normally, the Fund invests substantially all of its assets to meet its investment objective. The Fund may invest in securities with maturities of less than one year or cash equivalents, or it may hold cash, in order to collateralize its investments or for temporary defensive purposes. The percentage of the Fund invested in such holdings varies and depends on several factors,

including market conditions. For temporary defensive purposes and during periods of high cash inflows or outflows, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities, or it may hold cash. During such periods, the Fund may not be able to achieve its investment objective. The Fund may adopt a defensive strategy when the portfolio managers believe securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the Fund's SAI.

Risks of Investing in the Fund

Principal Risks

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CONCENTRATION RISK. The Fund is concentrated in the industries comprising the energy infrastructure sector. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development that affected a particular asset class, region or industry may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A concentration makes the Fund more susceptible to any single occurrence and may subject the Fund to greater volatility and market risk than a fund that is not so concentrated.

data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. These risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Advisor, distributor and other service providers (including, but not limited to, sub-advisors, index providers, fund accountants, custodians, transfer agents and administrators), market makers, authorized participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses; interference with the Fund’s ability to calculate its net asset value; disclosure of confidential trading information; impediments to trading; submission of erroneous trades or erroneous creation or redemption orders; the inability of the Fund or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines penalties, reputational damage, reimbursement or other compensation costs; or additional compliance costs. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. However, there is no guarantee that such efforts will succeed, and the Fund and its shareholders could be negatively impacted as a result.

ENERGY COMPANIES RISK. The Fund invests significantly in energy companies. The success of energy companies may be cyclical and highly dependent on energy prices. The market value of securities issued by energy companies may decline for many reasons, including, among other things, changes in the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production of energy sources, exchange rates, interest rates, economic conditions, tax treatment, energy conservation efforts, increased competition and technological advances. Energy companies may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of these companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of energy companies. Energy companies may also operate in, or engage in transactions involving, countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies may also face counterparty risk such that long term contracts may be declared void if the counterparty to those contracts enters into bankruptcy proceedings. Energy Companies that own interstate pipelines are subject to regulation by FERC with respect to the tariff rates they may charge for transportation services. An adverse determination by FERC with respect to the tariff rates of such a company could have a material adverse effect on its business, financial condition, results of operations and cash flows and its ability to pay cash distributions or dividends. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests.Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

Fund may underperform other funds that are not subject to such limits. In addition, companies selected for inclusion in the Fund may not ultimately undertake, or be successful in, their efforts to reduce the carbon impact of the production, transportation, conversion or storage of energy.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. Additionally, the COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative

than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

SMALLER COMPANIES RISK. The Fund may invest in the securities of small and/or mid capitalization companies. The stock price of small and/or mid capitalization companies may be more volatile than those of larger companies and therefore the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large capitalization companies. Stock prices of small and/or mid capitalization companies are also generally more vulnerable than those of large capitalization companies to adverse business and economic developments. Securities of small and/or mid capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small and/or mid capitalization companies are typically less financially stable than larger, more established companies and may reinvest a high proportion of their earnings in their business and may not pay dividends. Small and/or mid capitalization companies may also depend on a small number of essential personnel who may also be less experienced than the management of larger companies, making these companies more vulnerable to experiencing adverse effects due to the loss or inexperience of personnel. Small and/or mid capitalization companies also normally have less diverse product lines than those of large capitalization companies and are more susceptible to adverse developments concerning their products.

improvement programs; difficulty in raising adequate capital on reasonable terms in periods of high inflation and unsettled capital markets; governmental regulation of rates that the issuer can charge to customers; costs associated with compliance with, and adjusting to changes to, environmental and other regulations; counterparty risk; effects of economic slowdowns and surplus capacity; increased competition from other providers of utility services; costs associated with the reduced availability of certain types of fuel, occasionally reduced availability and high costs of natural gas for resale, and the effects of energy conservation policies. Some utility companies also face risks associated with the effects of a national energy policy and lengthy delays, and greatly increased costs and other problems, associated with the design, construction, licensing, regulation and operation of nuclear facilities for electric generation, including, among other considerations: the problems associated with the use of radioactive materials and the disposal of radioactive wastes; technological innovations that may render existing plants, equipment or products obsolete; difficulty in obtaining regulatory approval of new technologies; lack of compatibility of telecommunications equipment; potential impacts of terrorist activities on the utility industry and its customers; and the impact of natural or man-made disasters. Utility companies may also be subject to regulation by various governmental authorities and may be affected by the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. Deregulation is subjecting utility companies to greater competition and may adversely affect profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. There is no assurance that regulatory authorities will, in the future, grant rate increases, or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company.

Non-Principal Risks

DEPOSITARY RECEIPTS RISK. The Fund may invest in depositary receipts. Depository receipts are securities issued by a bank or trust company reflecting ownership of underlying securities issued by a foreign company. An investment in depositary receipts involves further risks due to certain unique features. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights pursuant to a deposit agreement between the underlying issuer and the depositary. In certain cases, the depositary will vote the shares deposited with it as directed by the underlying issuer’s board of directors. Furthermore, investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert shares into depositary receipts and vice versa. Such restrictions may cause shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipt. Moreover, if depositary receipts are converted into shares, the laws in certain countries may limit the ability of a non-resident to trade the shares and to reconvert the shares to depositary receipts. Depositary receipts may be “sponsored” or “unsponsored.” Sponsored depositary receipts are established jointly by a depositary and the underlying issuer, whereas unsponsored depositary receipts may be established by a depositary without participation by the underlying issuer. Holders of unsponsored depositary receipts generally bear all the costs associated with establishing the unsponsored depositary receipts. In addition, the issuers of the securities underlying unsponsored depositary receipts are not obligated to disclose material information in the U.S. and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts.

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed in the United States and abroad which may have a negative impact on certain companies in which the Fund invests. In addition, litigation regarding any of the issuers of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the portfolio managers determine to sell such a holding.

Dividends, Distributions and Taxes

Dividends from net investment income, if any, are declared and paid quarterly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

reached a conclusion with respect to, the federal income tax treatment of the assets to be included in the Fund. The following disclosure may not be sufficient for you to use for the purpose of avoiding penalties under federal tax law.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

Fund Status

Distributions

The Fund’s distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate, however, as further discussed below, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your shares, which could result in you having to pay higher taxes in the future when shares are sold, even if you sell the shares at a loss from your original investment. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Dividends Received Deduction

Capital Gains and Losses and Certain Ordinary Income Dividends

If you are an individual, the maximum marginal stated federal tax rate for net capital gain is generally 20% (15% or 0% for taxpayers with taxable income below certain thresholds). Some capital gain, including some portion of your capital gain dividends, may be taxed at a higher maximum stated tax rate. Some portion of your capital gain dividends may be attributable to your Fund’s interest in a master limited partnership which may be subject to a maximum marginal stated federal tax rate of 28%, rather than the rates set forth above. In the case of capital gain dividends, the determination of which portion of the capital gain dividend, if any, is subject to the 28% tax rate will be made based on rules prescribed by the United States Treasury. Capital gains may also be subject to the Medicare tax described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your share at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

Sale of Shares

If you sell or redeem your shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your shares from the amount you receive in the transaction. Your tax basis in your shares is generally equal to the cost of your shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and the cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

Non-U.S. Tax Credit

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will be characterized as dividends for federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below. However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

It is the responsibility of the entity through which you hold your shares to determine the applicable withholding.

Investments in Certain Non-U.S. Corporations

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

The Fund does not currently pay 12b-1 fees, and pursuant to a contractual arrangement, the Fund will not pay 12b-1 fees any time before March 31, 2022.. However, in the event 12b-1 fees are charged in the future, because these fees are paid out of the Fund's assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.

Net Asset Value

Nasdaq or the AIM, the securities are fair valued at the mean of the most recent bid and ask prices on such day. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities trading on Nasdaq or the AIM, are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at the closing bid price. Short-term investments that mature in less than 60 days when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discount, provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of determination. Net asset value may change on days when investors may not sell or redeem Fund shares.

General Description of the Trust and the Fund

The Trust was organized as a Massachusetts business trust on September 15, 2010 and is authorized to issue an unlimited number of shares in one or more series. The Trust is an open-end management investment company, registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust currently offers shares in nine series. This SAI relates to the Fund, which is a diversified series.

The Fund, as a series of the Trust, represents a beneficial interest in a separate portfolio of securities and other assets, with its own objectives and policies.

The Board of Trustees of the Trust (the “Board,”“Board of Trustees” or “Trustees”) has the right to establish additional series in the future, to determine the preferences, voting powers, rights and privileges thereof and to modify such preferences, voting powers, rights and privileges without shareholder approval. Shares of any series may also be divided into one or more classes at the discretion of the Trustees.

The Trust or any series or class thereof may be terminated at any time by the Board of Trustees upon written notice to the shareholders.

Each share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the rules promulgated thereunder. Shares of all series of the Trust vote together as a single class except as otherwise required by the 1940 Act, or if the matter being voted on affects only a particular series, and, if a matter affects a particular series differently from other series, the share of that series will vote separately on such matter. The Trust’s Declaration of Trust (the “Declaration”) requires a shareholder vote only on those matters where the 1940 Act requires a vote of shareholders and otherwise permits the Trustees to take actions without seeking the consent of shareholders. For example, the Declaration gives the Trustee broad authority to approve reorganizations between the Fund and another entity, such as another exchange-traded fund, or the sale of all or substantially all of the Fund’s assets, or the termination of the Trust or the Fund without shareholder approval if the 1940 Act would not require such approval.

The Declaration provides that by becoming a shareholder of the Fund, each shareholder shall be expressly held to have agreed to be bound by the provisions of the Declaration and to any By-laws adopted by the Trust. The Declaration provides that, except as set forth therein and authorized by the Trustees, shareholders have no rights, privileges, claims or remedies under any contract or agreement entered into by the Trust or the Fund with any service provider or other agent to or contractor with the Trust or the Fund including, without limitation, any third party beneficiary rights.

The Declaration also provides that Trustees may be removed, with or without cause, by a vote of shareholders holding at least two-thirds of the voting power of the Trust, or by a vote of two-thirds of the remaining Trustees. The provisions of the Declaration relating to the election and removal of Trustees may not be amended without the approval of two-thirds of the Trustees.

The holders of Fund shares are required to disclose information on direct or indirect ownership of Fund shares as may be required to comply with various laws applicable to the Fund or as the Trustees may determine, and ownership of Fund shares may be disclosed by the Fund if so required by law or regulation. In addition, pursuant to the Declaration, the Trustees may, in their discretion, require the Trust to redeem shares held by any shareholder for any reason under terms set by the Trustees.

The Declaration provides a detailed process for the bringing of derivative actions by shareholders in order to permit legitimate inquiries and claims while avoiding the time, expense, distraction and other harm that can be caused to the Fund or its shareholders as a result of spurious shareholder demands and derivative actions. In addition, the Declaration provides that actions that are derivative in nature may not be brought directly. Prior to bringing a derivative action, a demand must first be made on the Trustees. The Declaration details various information, certifications, undertakings and acknowledgements that must be included in the demand. Following receipt of the demand, the Trustees have a period of 90 days, which may be extended by an additional 60 days, to consider the demand. If a majority of the Trustees who are considered independent for the purposes of considering the demand determine that maintaining the suit would not be in the best interests of the Fund, the Trustees are required to reject the demand and the complaining shareholder may not proceed with the derivative

action unless the shareholder is able to sustain the burden of proof to a court that the decision of the Trustees not to pursue The requested action was not a good faith exercise of their business judgment on behalf of the Fund. In making such a determination, a Trustee is not considered to have a personal financial interest by virtue of being compensated for his or her services as a Trustee. If a demand is rejected, the complaining shareholder will be responsible for the costs and expenses (including attorneys’ fees) incurred by the Fund in connection with the consideration of the demand under a number of circumstances. In addition, if a court determines that a derivative action was made without reasonable cause or for an improper purpose, or if a derivative or direct action is dismissed on the basis of a failure to comply with the procedural provisions relating to shareholder actions as set forth in the Declaration, or if a direct action is dismissed by a court for failure to state a claim, the shareholder bringing the action may be responsible for the Fund’s costs, including attorneys’ fees.

The provisions of the Declaration provide that any direct or derivative action commenced by a shareholder must be brought only in the U.S. District Court for the District of Massachusetts (Boston Division) or if any such action may not be brought in that court, then in the Business Litigation Session of Suffolk Superior Court in Massachusetts (the “Chosen Courts”). Except as prohibited by applicable law, if a shareholder commences an applicable action in a court other than a Chosen Court without the consent of the Fund, then such shareholder may be obligated to reimburse the Fund and any applicable Trustee or officer of the Fund made party to such proceeding for the costs and expenses (including attorneys’ fees) incurred in connection with any successful motion to dismiss, stay or transfer of the action. The Declaration also provides that any shareholder bringing an action against the Fund waives the right to trial by jury to the fullest extent permitted by law.

The Trust is not required to and does not intend to hold annual meetings of shareholders.

Under Massachusetts law applicable to Massachusetts business trusts, shareholders of such a trust may, under certain circumstances, be held personally liable as partners for its obligations. However, the Declaration contains an express disclaimer of shareholder liability for acts or obligations of the Trust and requires that notice of this disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or the Trustees. The Declaration further provides for indemnification out of the assets and property of the Trust for all losses and expenses of any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which both inadequate insurance existed and the Trust or the Fund itself was unable to meet its obligations.

The Declaration further provides that a Trustee acting in his or her capacity as Trustee is not personally liable to any person other than the Trust, for any act, omission, or obligation of the Trust. The Declaration requires the Trust to indemnify any persons who are or who have been Trustees, officers or employees of the Trust for any liability for actions or failure to act except to the extent prohibited by applicable federal law. In making any determination as to whether any person is entitled to the advancement of expenses in connection with a claim for which indemnification is sought, such person is entitled to a rebuttable presumption that he or she did not engage in conduct for which indemnification is not available. The Declaration provides that any Trustee who serves as chair of the Board of Trustees or of a committee of the Board of Trustees, as lead independent Trustee or as audit committee financial expert, or in any other similar capacity will not be subject to any greater standard of care or liability because of such position.

The Declaration further provides that no provision of the Declaration will restrict any shareholder rights expressly granted by the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended or the 1940 Act, or any rule, regulation or order of the Securities Exchange Commission thereunder.

The Fund is advised by First Trust Advisors L.P. (the “Advisor” or “First Trust”).

The shares of the Fund are principally listed and traded on The Nasdaq Stock Market LLC (“Nasdaq” or the “Exchange”). ETFs, such as the Fund, do not sell or redeem individual shares of the Fund. Instead, financial entities known as “authorized participants” (which are discussed in greater detail below) that have contractual arrangements with the Fund or the Distributor to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” An authorized participant that purchases a Creation Unit of Fund shares deposits with the Fund a “basket” of securities, cash and/or other assets identified by the Fund that day, and then receives the Creation Unit of Fund shares in return for those assets. The redemption process is the reverse of the purchase process: the authorized participant redeems a Creation Unit of Fund shares for a basket of securities, cash and/or other assets. The basket is generally representative of the Fund’s portfolio, and together with a cash balancing amount, it is equal to the NAV of the Fund shares comprising the Creation Unit. Pursuant to Rule 6c-11 of the 1940 Act, the Fund may utilize baskets that are not representative of the Fund’s portfolio. Such “custom baskets” are discussed in the section entitled “Creation and Redemption of Creation Units.”

Fund shares may be issued in advance of receipt of Deposit Securities subject to various conditions including a requirement to maintain on deposit with the Fund cash at least equal to 115% of the market value of the missing Deposit Securities. See the section entitled “Creation and Redemption of Creation Units.” In each instance of such cash creations or redemptions, transaction fees may be imposed that will be higher than the transaction fees associated with in-kind creations or redemptions. In all cases, such fees will be limited in accordance with the requirements of the SEC applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

There can be no assurance that the requirements of the Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Exchange may, but is not required to, remove the shares of the Fund from listing if (i) following the initial 12-month period beginning at the commencement of trading of the Fund, there are fewer than 50 beneficial owners of the shares of the Fund for 30 or more consecutive trading days; or (ii) such other event shall occur or condition exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. The Exchange will remove the shares of the Fund from listing and trading upon termination of the Fund.

As in the case of other stocks traded on the Exchange, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

The Fund reserves the right to adjust the price levels of shares in the future to help maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

The Fund is required by the Exchange to comply with certain listing standards (which includes certain investment parameters) in order to maintain its listing on the Exchange. Compliance with these listing standards may compel the Fund to sell securities at inopportune time or for a price other than the security’s then-current market value. The sale of securities in such circumstances could limit the Fund’s profit or require the Fund to incur a loss, and as a result, the Fund’s performance could be impacted.

Investment Objective and Policies

The Prospectus describes the investment objective and certain policies of the Fund. The following supplements the information contained in the Prospectus concerning the investment objective and policies of the Fund.

The Fund is subject to the following fundamental policies, which may not be changed without approval of the holders of a majority of the outstanding voting securities (as such term is defined in the 1940 Act) of the Fund:

(1)

The Fund may not issue senior securities, except as permitted under the 1940 Act.

(2)

The Fund may not borrow money, except that the Fund may (i) borrow money from banks for temporary or emergency purposes (but not for leverage or the purchase of investments) and (ii) engage in other transactions permissible under the 1940 Act that may involve a borrowing (such as obtaining short-term credits as are necessary for the clearance of transactions, engaging in delayed-delivery transactions, or purchasing certain futures, forward contracts and options), provided that the combination of (i) and (ii) shall not exceed 33⅓% of the value of the Fund’s total assets (including the amount borrowed), less the Fund’s liabilities (other than borrowings).

(3)

The Fund will not underwrite the securities of other issuers except to the extent the Fund may be considered an underwriter under the Securities Act of 1933, as amended (the “1933 Act”), in connection with the purchase and sale of portfolio securities.

(4)

The Fund will not purchase or sell real estate or interests therein, unless acquired as a result of ownership of securities or other instruments (but this shall not prohibit the Fund from purchasing or selling securities or other instruments backed by real estate or of issuers engaged in real estate activities).

(5)

The Fund may not make loans to other persons, except through (i) the purchase of debt securities permissible under the Fund’s investment policies, (ii) repurchase agreements, or (iii) the lending of portfolio securities, provided that no such loan of portfolio securities may be made by the Fund if, as a result, the aggregate of such loans would exceed 33⅓% of the value of the Fund’s total assets.

(6)

The Fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts, forward contracts or other derivative instruments, or from investing in securities or other instruments backed by physical commodities).

(7)

The Fund may not invest 25% or more of the value of its total assets in securities of issuers in any one industry. This restriction does not apply to obligations issued or guaranteed by the U.S. government or its agencies or instrumentalities.

For purposes of applying restriction (1) above, under the 1940 Act as currently in effect, the Fund is not permitted to issue senior securities, except that the Fund may borrow from any bank if immediately after such borrowing and at all times thereafter, the value of the Fund’s total assets is at least 300% of the principal amount of all of the Fund’s borrowings (i.e., the principal amount of the borrowings may not exceed 33⅓% of the Fund’s total assets). In the event that such asset coverage shall at any time fall below 300% the Fund shall, within three days thereafter (not including Sundays and holidays), reduce the amount of its borrowings to an extent that the asset coverage of such borrowings shall be at least 300%.

Except for restriction (2) above, if a percentage restriction is adhered to at the time of investment, a later increase in percentage resulting from a change in market value of the investment or the total assets will not constitute a violation of that restriction. With respect to restriction (2), if the limitations are exceeded as a result of a change in market value then the Fund will reduce the amount of borrowings within three days thereafter to the extent necessary to comply with the limitations (not including Sundays and holidays).

The fundamental investment limitations set forth above limit the Fund’s ability to engage in certain investment practices and purchase securities or other instruments to the extent permitted by, or consistent with, applicable law. As such, these limitations will change as the statute, rules, regulations or orders (or, if applicable, interpretations) change, and no shareholder vote will be required or sought.

The Fund’s investment objective and the foregoing fundamental policies of the Fund may not be changed without the affirmative vote of the majority of the outstanding voting securities of the Fund. The 1940 Act defines a majority vote as the vote of the lesser of (i) 67% or more of the voting securities represented at a meeting at which more than 50% of the outstanding securities are represented; or (ii) more than 50% of the outstanding voting securities. With respect to the submission of a change in an investment policy to the holders of outstanding voting securities of the Fund, such matter shall be deemed to have been effectively acted upon with respect to the Fund if a majority of the outstanding voting securities of the Fund vote for the approval of such matter, notwithstanding that such matter has not been approved by the holders of a majority of the outstanding voting securities of any other series of the Trust affected by such matter.

In addition to the foregoing fundamental policies, the Fund is also subject to strategies and policies discussed herein which, unless otherwise noted, are non-fundamental restrictions and policies and may be changed by the Board of Trustees.

Investment Strategies

The following information supplements the discussion of the Fund’s investment objective, policies and strategies that appears in the Prospectus.

The Fund seeks to achieve its investment objective by investing in a portfolio of U.S. dollar-denominated fixed and variable rate instruments including securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities, residential and commercial mortgage-backed securities, asset-backed securities, U.S. corporate bonds, fixed income securities issued by non-U.S. corporations and governments, municipal obligations, privately issued securities and other debt securities bearing fixed or floating interest rates. The Fund may also invest in money market securities.

Types of Investments

the principal and interest due them and may have a prior claim over other creditors if liens or mortgages are involved. Interest on corporate bonds may be fixed or floating, or the securities may be zero coupon fixed-income securities which pay no interest. Interest on corporate bonds is typically paid semi-annually and is fully taxable to the holder of the bonds. Corporate bonds contain elements of both interest rate risk and credit risk. The market value of a corporate bond generally may be expected to rise and fall inversely with changes in interest rates and may also be affected by the credit rating of the issuer, the issuer’s performance and perceptions of the issuer in the marketplace. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk.

Credit Linked Notes. Credit linked notes are structured securities typically issued by banks whose principal and interest payments are contingent on the performance of a reference issuer. Credit linked notes are created by embedding a credit default swap in a funded asset to form an investment whose credit risk and cash flow characteristics resemble those of a bond or loan. These credit linked notes pay an enhanced coupon to the investor for taking on the added credit risk of the reference issuer.

Delayed-Delivery Transactions. The Fund may from time to time purchase securities on a “when-issued” or other delayed-delivery basis. The price of securities purchased in such transactions is fixed at the time the commitment to purchase is made, but delivery and payment for the securities take place at a later date. During the period between the purchase and settlement, the Fund does not remit payment to the issuer, no interest is accrued on debt securities and dividend income is not earned on equity securities. Delayed-delivery commitments involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, which risk is in addition to the risk of a decline in value of the Fund’s other assets. While securities purchased in delayed-delivery transactions may be sold prior to the settlement date, the Fund intends to purchase such securities with the purpose of actually acquiring them. At the time the Fund makes the commitment to purchase a security in a delayed-delivery transaction, it will record the transaction and reflect the value of the security in determining its net asset value.

The Fund will earmark or maintain in a segregated account cash, U.S. government securities, and high-grade liquid debt securities equal in value to commitments for delayed-delivery securities. Such earmarked or segregated securities will mature or, if necessary, be sold on or before the settlement date. When the time comes to pay for delayed-delivery securities, the Fund will meet its obligations from then-available cash flow, sale of the securities earmarked or held in the segregated account described above, sale of other securities, or, although it would not normally expect to do so, from the sale of the delayed-delivery securities themselves (which may have a market value greater or less than the Fund’s payment obligation).

Although the Prospectus and this SAI describe certain permitted methods of segregating assets or otherwise “covering” certain transactions, such descriptions are not all-inclusive. The Fund may segregate against or cover such transactions using other methods permitted under the 1940 Act, the rules and regulations thereunder, or orders issued by the SEC thereunder.

Fixed Income Investments and Cash Equivalents. Normally, the Fund invests substantially all of its assets to meet its investment objectives and consequently may invest significantly in fixed income securities and cash equivalents; however, for temporary or defensive purposes, the Fund may also invest in other fixed income investments and cash equivalents in order to provide income, liquidity and preserve capital.

Fixed income investments and cash equivalents held by the Fund may include, without limitation, the types of investments set forth below:

(1)

agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. In addition, the Fund may invest in sovereign debt obligations of non-U.S. countries. A sovereign debtor’s willingness or ability to repay principal and interest in a timely manner may be affected by a number of factors, including its cash flow situation, the extent of its non-U.S. reserves, the availability of sufficient non-U.S. exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders and the political constraints to which it may be subject.

(2)

The Fund may invest in certificates of deposit issued against funds deposited in a bank or savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. If such certificates of deposit are non-negotiable, they will be considered illiquid securities and be subject to the Fund’s 15% restriction on investments in illiquid securities. Pursuant to the certificate of deposit, the issuer agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by the Fund may not be fully insured. The Fund may only invest in certificates of deposit issued by U.S. banks with at least $1 billion in assets.

(3)

The Fund may invest in bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions. Generally, an acceptance is a time draft drawn on a bank by an exporter or an importer to obtain a stated amount of funds to pay for specific merchandise. The draft is then “accepted” by a bank that, in effect, unconditionally guarantees to pay the face value of the instrument on its maturity date. The acceptance may then be held by the accepting bank as an asset or it may be sold in the secondary market at the going rate of interest for a specific maturity.

(4)

The Fund may invest in repurchase agreements, which involve purchases of debt securities with counterparties that are deemed by the Advisor to present acceptable credit risks. In such an action, at the time the Fund purchases the security, it simultaneously agrees to resell and redeliver the security to the seller, who also simultaneously agrees to buy back the security at a fixed price and time. This assures a predetermined yield for the Fund during its holding period since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. government or its agencies or instrumentalities, certificates of deposit, or bankers’ acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, however, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. The portfolio managers monitor the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The portfolio managers do so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(5)

The Fund may invest in bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest. There may be penalties for the early withdrawal of such time deposits, in which case the yields of these investments will be reduced.

(6)

continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. The Fund may only invest in commercial paper rated A-3 or higher by S&P Ratings, Prime-3 or higher by Moody’s or F3 or higher by Fitch.

(7)

The Fund may invest in shares of money market funds, as consistent with its investment objectives and policies. Shares of money market funds are subject to management fees and other expenses of those funds. Therefore, investments in money market funds will cause the Fund to bear proportionately the costs incurred by the money market funds’ operations. At the same time, the Fund will continue to pay its own management fees and expenses with respect to all of its assets, including any portion invested in the shares of other investment companies. It is possible for the Fund to lose money by investing in money market funds.

High Yield Securities. The Fund may invest in securities that are rated below investment grade, commonly referred to as “junk” bonds, at the time of purchase. The ratings of a rating agency represent its opinion as to the quality of securities it undertakes to rate. Ratings are not absolute standards of quality; consequently, securities with the same maturity, duration, coupon and rating may have different yields. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. If a security owned by the Fund is subsequently downgraded, the Fund will not be required to dispose of such security. If a downgrade occurs, the Advisor will consider what action, including the sale of such security, is in the best interests of the Fund. The Credit Rating Definitions, as published by the three major rating agencies, are set forth in Exhibit B to this SAI.

Because the risk of default is higher for below investment grade securities than for investment grade securities, the Advisor’s research and credit analysis will be an especially important part of managing securities of this type. The Advisor will attempt to identify those issuers of below investment grade securities whose financial condition the Advisor believes are adequate to meet future obligations or who have improved or are expected to improve in the future. The Advisor’s analysis focuses on relative values based on such factors as interest or dividend coverage, asset coverage, earnings prospects and the experience and managerial strength of the issuer.

Illiquid Securities. The Fund may invest in illiquid securities (i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For purposes of this restriction, illiquid securities may include, but are not limited to, certain restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the 1933 Act and repurchase agreements with maturities in excess of seven days, among others. However, the Fund will not acquire illiquid securities if, as a result, such securities would comprise more than 15% of the value of the Fund’s net assets. The Advisor, subject to oversight by the Board of Trustees, has the ultimate authority to determine, to the extent permissible under the federal securities laws, which securities are liquid or illiquid for purposes of this 15% limitation under the Fund’s liquidity risk management program, adopted pursuant to Rule 22e-4 under the 1940 Act.

Restricted securities may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the 1933 Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. Illiquid securities will be priced at fair value as determined in good faith under procedures adopted by the Board of Trustees. If, through the appreciation of illiquid securities or the depreciation of liquid securities, the Fund should be in a position where more than 15% of the value of its net assets are invested in illiquid securities, including restricted securities which are not readily marketable, the Advisor will report such occurrence to the Board of Trustees and take such steps as are deemed advisable to protect liquidity in accordance with the Fund’s liquidity risk management program.

Investment Companies and Other Pooled Investment Vehicles. The Fund may invest in other pooled investment vehicles, including open-end or closed-end investment companies, other exchange-traded funds (“ETFs”) and business development companies that invest primarily in securities of the types in which the Fund may invest directly. An ETF is a fund that holds a portfolio of securities and trades on a securities exchange and its shares may, at times, trade at a premium or discount to its net asset value. As a shareholder in a pooled investment vehicle, the Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the Fund’s management fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other pooled investment vehicles. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and closed-end funds. Other pooled investment

vehicles may be leveraged, and the net asset value and market value of their securities will therefore be more volatile and the yield to shareholders will tend to fluctuate more than the yield of unleveraged pooled investment vehicles.

Loans. The Fund may invest in fixed and floating rate loans (“Loans”). Loans may include senior floating rate loans (“Senior Loans”) and secured and unsecured loans, second lien or more junior loans and bridge loans (“Junior Loans”). Loans are typically arranged through private negotiations between borrowers in the United States or in foreign or emerging markets which may be corporate issuers or issuers of sovereign debt obligations (“Obligors”) and one or more financial institutions and other lenders (“Lenders”). The Fund may invest in Loans by purchasing assignments of all or a portion of Loans (“Assignments”) or Loan participations (“Participations”) from third parties.

The Fund has direct rights against the Obligor on the Loan when it purchases an Assignment. Assignments are arranged through private negotiations between potential assignees and potential assignors. With respect to Participations, typically, the Fund will have a contractual relationship only with the Lender and not with the Obligor. The agreement governing Participations may limit the rights of the Fund to vote on certain changes which may be made to the Loan agreement, such as waiving a breach of a covenant. However, the holder of a Participation will generally have the right to vote on certain fundamental issues such as changes in principal amount, payment dates and interest rate. Participations may entail certain risks relating to the creditworthiness of the parties from which the participations are obtained.

A Loan is typically originated, negotiated and structured by a U.S. or foreign commercial bank, insurance company, finance company or other financial institution (the “Agent”) for a group of Loan investors. The Agent typically administers and enforces the Loan on behalf of the other Loan investors in the syndicate. The Agent’s duties may include responsibility for the collection of principal and interest payments from the Obligor and the apportionment of these payments to the credit of all Loan investors. The Agent is also typically responsible for monitoring compliance with the covenants contained in the Loan agreement based upon reports prepared by the Obligor. In addition, an institution, typically but not always the Agent, holds any collateral on behalf of the Loan investors. In the event of a default by the Obligor, it is possible, though unlikely, that the Fund could receive a portion of the borrower’s collateral. If the Fund receives collateral other than cash, any proceeds received from liquidation of such collateral will be available for investment as part of the Fund’s portfolio.

There may be instances in which the Fund is required to vote upon amendments to certain of the Loans in which it invests. In these cases, the Fund will attempt to ensure that such amendments are voted consistently and solely in the best interests of the Fund.

Money Market Funds. The Fund may invest in shares of money market funds to the extent permitted by the 1940 Act.

Mortgage-Backed Securities. The Fund normally expects to invest in mortgage-backed securities tied to residential and commercial mortgages, including, among other things, RMBS and CMBS. Mortgage-backed securities represent an interest in a pool of mortgage loans made by banks and other financial institutions to finance purchases of homes, commercial buildings and other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors. As the underlying mortgage loans are paid off, investors receive principal and interest payments. Mortgage-backed securities may be fixed-rate or adjustable-rate mortgage-backed securities (“ARMS”). Certain mortgage-backed securities (including RMBS and CMBS), where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest, are referred to as stripped mortgage-backed securities (“SMBS”). Further, mortgage-backed securities can also be categorized as collateralized mortgage obligations (“CMOs”) or real estate mortgage investment conduits (“REMICs”) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets.

of principal and interest that is backed by the full faith and credit of the U.S. government. However, the full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. Fannie Mae and Freddie Mac pass-through mortgage certificates are backed by the credit of the respective instrumentality and are not guaranteed by the U.S. government. Other securities issued by government agencies or instrumentalities, including government-sponsored entities, may only be backed by the creditworthiness of the issuing institution, not the U.S. government, or the issuers may have the right to borrow from the U.S. Treasury to meet their obligations. Many mortgage-backed securities are pass-through securities, which means they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately. Adjustable-rate mortgage-backed securities include ARMS and other mortgage-backed securities with interest rates that adjust periodically to reflect prevailing market rates.

Municipal Bonds. The two general classifications of municipal bonds are “general obligation” bonds and “revenue” bonds. General obligation bonds are secured by the governmental issuer’s pledge of its faith, credit and taxing power for the payment of principal and interest upon a default by the issuer of its principal and interest payment obligations. They are usually paid from general revenues of the issuing governmental entity. Revenue bonds, on the other hand, are usually payable only out of a specific revenue source rather than from general revenues. Revenue bonds ordinarily are not backed by the faith, credit or general taxing power of the issuing governmental entity. The principal and interest on revenue bonds for private facilities are typically paid out of rents or other specified payments made to the issuing governmental entity by a private company which uses or operates the facilities. Examples of these types of obligations are industrial revenue bond and pollution control revenue bonds. Industrial revenue bonds are issued by governmental entities to provide financing aid to community facilities such as hospitals, hotels, business or residential complexes, convention halls and sport complexes. Pollution control revenue bonds are issued to finance air, water and solids pollution control systems for privately operated industrial or commercial facilities.

Municipal Bonds and Other Municipal Obligations. The Fund invests in municipal bonds and other municipal obligations. These bonds and other obligations are issued by the states and by their local and special-purpose political subdivisions. The term “municipal bond” includes short-term municipal notes issued by the states and their political subdivisions, including, but not limited to, tax anticipation notes (“TANs”), bond anticipation notes (“BANs”), revenue anticipation notes (“RANs”), construction loan notes, tax free commercial paper, and tax free participation certificates. In general, municipal obligations include debt obligations issued by states, cities and local authorities to obtain funds for various public purposes, including construction of a wide range of public facilities such as airports, bridges, highways, hospitals, housing, mass transportation, schools, streets and water and sewer works. Industrial development bonds and pollution control bonds that are issued by or on behalf of public authorities to finance various privately-rated facilities are included within the term municipal obligations if the interest paid thereon is exempt from federal income tax.

Obligations of issuers of municipal obligations are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal and/or interest, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal obligations may be materially affected.

Non -U.S. Investments. Non-U.S. securities include securities issued or guaranteed by companies organized under the laws of countries other than the United States (including emerging markets), securities issued or guaranteed by foreign, national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities and debt obligations of supranational governmental entities such as the World Bank or European Union. Non-U.S. securities may also include U.S. dollar-denominated debt obligations, such as “Yankee Dollar” obligations, of foreign issuers and of supra-national government entities. Yankee Dollar obligations are U.S. dollar-denominated obligations issued in the U.S. capital markets by foreign corporations, banks and governments. Foreign securities also may be traded on foreign securities exchanges or in over-the-counter (“OTC”) capital markets.

will generally be the difference between the bid and offer spot rate of the currency being purchased or sold. In order to protect against uncertainty in the level of future currency exchange rates, the Fund is authorized to enter into various currency exchange transactions.

Other Loans. The Fund may invest in secured loans that are not first lien and loans that are unsecured. These loans have the same characteristics as Senior Loans except that such loans are not first in priority of repayment and/or are not secured by collateral. Accordingly, the risks associated with these loans are higher than the risks for loans with first priority over the collateral. Because these loans are lower in priority and/or unsecured, they are subject to the additional risk that the cash flow of the borrower may be insufficient to meet scheduled payments after giving effect to the secured obligations of the borrower. In the event of default on such a loan, the first priority lien holder has first claim to the underlying collateral of the loan. It is possible that no value would remain for the holders of secured loans that are not first lien and loans that are unsecured and therefore result in a loss of investment to the Fund.

Secured loans that are not first lien and loans that are unsecured generally have greater price volatility than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in these loans, which would create greater credit risk exposure for the holders of such loans. Secured loans that are not first lien and loans that are unsecured share the same risks as other below investment grade instruments.

Additional Information Concerning Senior Loans. Senior Loans typically hold the most senior position in the capital structure of the Obligor, are typically secured with specific collateral and have a claim on the assets and/or stock of the Obligor that is senior to that held by subordinated debtholders and shareholders of the Obligor. Collateral for Senior Loans may include (i) working capital assets, such as accounts receivable and inventory; (ii) tangible fixed assets, such as real property, buildings and equipment; (iii) intangible assets, such as trademarks and patent rights; and/or (iv) security interests in shares of stock of subsidiaries or affiliates.

Additional Information Concerning Synthetic Letters of Credit. Loans may include synthetic letters of credit. In a synthetic letter of credit transaction, the lender typically creates a special purpose entity or a credit-linked deposit account for the purpose of funding a letter of credit to the borrower. When the Fund invests in a synthetic letter of credit, the Fund is typically paid a rate based on the lender’s borrowing costs and the terms of a synthetic letter of credit. Synthetic letters of credit are typically structured as assignments with the Fund acquiring direct rights against the Obligor.

Additional Information Concerning Unfunded Commitments. Unfunded commitments are contractual obligations pursuant to which the Fund agrees to invest in a loan at a future date. Typically, the Fund receives a commitment fee for entering into the unfunded commitment.

Portfolio Turnover

The Fund buys and sells portfolio securities in the normal course of its investment activities. The proportion of the Fund's investment portfolio that is bought and sold during a year is known as the Fund's portfolio turnover rate. A portfolio turnover rate of 100% would occur, for example, if all of the portfolio securities (other than short-term securities) were replaced once during the fiscal year. A high portfolio turnover rate could result in the payment by the Fund of increased brokerage costs, expenses and taxes. The portfolio turnover rates for the specified periods are set forth in the table below. Significant variations in portfolio turnover from year-to-year are generally the result of fluctuations in the size of the Fund or changes to the Fund’s portfolio holdings.

Lending of Portfolio Securities

banks or other institutions which First Trust has determined are creditworthy under guidelines approved by the Board of Trustees. The First Trust Funds will pay a portion of the income earned on the lending transaction to the placing broker and may pay administrative and custodial fees in connection with these loans. First Trust may select the First Trust Fund to participate in the securities lending program, at its discretion with notice to the Board of Trustees.

In these loan arrangements, the First Trust Funds will receive collateral in the form of cash, U.S. government securities or other high-grade debt obligations equal to at least 102% (for domestic securities) or 105% (for international securities) of the market value of the securities loaned as determined at the time of loan origination. This collateral must be valued daily by First Trust or the First Trust Fund’s lending agent and, if the market value of the loaned securities increases, the borrower must furnish additional collateral to the lending First Trust Fund. During the time portfolio securities are on loan, the borrower pays the lending First Trust Fund any dividends or interest paid on the securities. Loans are subject to termination at any time by the lending First Trust Fund or the borrower. While a First Trust Fund does not have the right to vote securities on loan, it would terminate the loan and regain the right to vote if that were considered important with respect to the investment. When a First Trust Fund lends portfolio securities to a borrower, payments in lieu of dividends made by the borrower to the First Trust Fund will not constitute “qualified dividends” taxable at the same rate as long-term capital gains, even if the actual dividends would have constituted qualified dividends had the First Trust Fund held the securities. Please see "Securities Lending Risk" below for a description of the risks associated with securities lending activities.

Investment Risks

The following risk disclosure supplements the discussion of the Fund’s investment risks that appears in the Prospectus.

Overview

An investment in the Fund should be made with an understanding of the risks that an investment in the Fund’s shares entails, including the risk that the financial condition of the issuers of the securities held by the Fund or the general condition of the securities market may worsen and the value of the securities and therefore the value of the Fund may decline. The Fund may not be an appropriate investment for those who are unable or unwilling to assume the risks involved generally with such an investment. The past market and earnings performance of any of the securities included in the Fund is not predictive of their future performance.

Agency Mortgage Related Securities Risk

Agency mortgage-related securities are instruments that are guaranteed by the U.S. government through agencies such as Ginnie Mae, and are backed by the full faith and credit of the U.S. government. Other agency mortgage-related securities are guaranteed by government-related agencies, such as Fannie Mae, but are not backed by the full faith and credit of the U.S. government. On September 6, 2008, Fannie Mae and Freddie Mac were placed in conservatorship under the Federal Housing Finance Agency (“FHFA”). FHFA has all rights, titles, powers and privileges of Fannie Mae and Freddie Mac and their assets. In addition, the U.S. Treasury entered into a Senior Preferred Stock Purchase Agreement with Fannie Mae and Freddie Mac. In connection with the Senior Preferred Stock Purchase Agreement, Fannie Mae and Freddie Mac are required to submit an annual risk management plan to the U.S. Treasury. Both Fannie Mae and Freddie Mac continue to operate under the conservatorship of FHFA and the funding from the Senior Preferred Stock Purchase Agreement to meet their obligations. As conservator, FHFA has the authority to, among other things, repudiate contracts and sell assets or liabilities of Fannie Mae and Freddie Mac without prior approval or consent. Parties holding Fannie Mae or Freddie Mac mortgage-backed securities would have to rely on the satisfaction of those loans and would be exposed to the counterparty’s credit risk in the event FHFA repudiates such a contract or sells the assets or liabilities of such a contract.

Agent Risk

Selling lenders, Agents and other entities that may be positioned between the Fund and the Obligor will likely conduct their principal business activities in the banking, finance and financial services industries. Investments in loans may be more impacted by a single economic, political or regulatory occurrence affecting such industries than other types of investments. Entities engaged in such industries may be more susceptible to, among other things, fluctuations in interest rates, changes in the Federal Open Market Committee’s monetary policy, government regulations concerning such industries and concerning capital raising activities generally and fluctuations in the financial markets generally. An Agent, lender or other entity positioned between the Fund and the Obligor may become insolvent or enter FDIC receivership or bankruptcy. The Fund might incur certain costs and delays in realizing payment on a loan or suffer a loss of principal and/or interest if assets or interests held

by the Agent, lender or other party positioned between the Fund and the Obligor are determined to be subject to the claims of the Agent’s, lender’s or such other party’s creditors.

Collateral, Subordination and Litigation Risk

With respect to loans that are secured, the Fund is subject to the risk that collateral securing the loan will decline in value or have no value or that the Fund’s lien is or will become junior in payment to other liens. A decline in value, whether as a result of bankruptcy proceedings or otherwise, could cause the loan to be undercollateralized or unsecured. There may be no formal requirement for the Obligor to pledge additional collateral. In addition, collateral may consist of assets that may not be readily liquidated, and there is no assurance that the liquidation of such assets would satisfy an Obligor’s obligation on a loan.

If an Obligor becomes involved in bankruptcy proceedings, a court may invalidate the loan or the Fund’s security interest in loan collateral or subordinate the Fund’s rights under a Senior Loan or Junior Loan to the interest of the Obligor’s other creditors, including unsecured creditors, or cause interest or principal previously paid to be refunded to the Obligor. If a court required interest or principal to be refunded, it could negatively affect Fund performance. Such action by a court could be based, for example, on a “fraudulent conveyance” claim to the effect that the Obligor did not receive fair consideration for granting the security interest in the loan collateral to the Fund. For Senior Loans made in connection with a highly leveraged transaction, consideration for granting a security interest may be deemed inadequate if the proceeds of the loan were not received or retained by the Obligor, but were instead paid to other persons (such as shareholders of the Obligor) in an amount which left the Obligor insolvent or without sufficient working capital. There are also other events, such as the failure to perfect a security interest due to faulty documentation or faulty official filings, which could lead to the invalidation of the Fund’s security interest in loan collateral. If the Fund’s security interest in loan collateral is invalidated or the Senior Loan is subordinated to other debt of an Obligor in bankruptcy or other proceedings, the Fund would have substantially lower recovery, and perhaps no recovery on the full amount of the principal and interest due on the loan, or the Fund could have to refund interest.

Lenders and investors in loans can be sued by other creditors and shareholders of the Obligors. Losses can be greater than the original loan amount and occur years after the principal and interest on the loan have been repaid.

Credit Rating Agency Risk

Credit ratings are determined by credit rating agencies such as Standard & Poor’s, Moody’s Investors Service, Inc. and Fitch Ratings, and are only the opinions of such entities. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risk or the liquidity of securities. Any shortcomings or inefficiencies in credit rating agencies’ processes for determining credit ratings may adversely affect the credit ratings of securities held by the Fund and, as a result, may adversely affect those securities’ perceived or actual credit risk.

Derivatives Risk

The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivatives. In addition, when the Fund invests in certain derivative securities, including, but not limited to, when-issued securities, forward commitments, futures contracts and interest rate swaps, the Fund is effectively leveraging its investments, which could result in exaggerated changes in the net asset value of the Fund’s shares and can result in losses that exceed the amount originally invested. The success of the Advisor’s derivatives strategies will depend on its ability to assess and predict the impact of market or economic developments on the underlying asset, index or rate and the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions. Liquidity risk exists when a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Additionally, certain risks associated with an investment in derivatives may also include: market risk, credit risk, correlation risk, liquidity risk, legal risk and systemic or “interconnection” risk, as specified below.

(1)

the Advisor’s judgment that the derivative transaction will provide value to the Fund and its shareholders and is consistent with the Fund’s objective, investment limitations, and operating policies. In making such a judgment, the Advisor will analyze the benefits and risks of the derivative transactions and weigh them in the context of the Fund’s overall investments and investment objective.

(2)

Credit Risk/Counterparty Risk. Credit risk is the risk that a loss may be sustained as a result of the failure of a counterparty to comply with the terms of a derivative instrument. The counterparty risk for exchange-traded derivatives is generally less than for privately-negotiated or OTC derivatives, since generally a clearing agency, which is the issuer or counterparty to each exchange-traded instrument, provides a guarantee of performance. For privately-negotiated instruments, there is no similar clearing agency guarantee. In all transactions, the Fund will bear the risk that the counterparty will default, and this could result in a loss of the expected benefit of the derivative transactions and possibly other losses to the Fund. The Fund will enter into transactions in derivative instruments only with counterparties that First Trust reasonably believes are capable of performing under the contract.

(3)

Correlation Risk. Correlation risk is the risk that there might be an imperfect correlation, or even no correlation, between price movements of a derivative instrument and price movements of investments being hedged. When a derivative transaction is used to completely hedge another position, changes in the market value of the combined position (the derivative instrument plus the position being hedged) result from an imperfect correlation between the price movements of the two instruments. With a perfect hedge, the value of the combined position remains unchanged with any change in the price of the underlying asset. With an imperfect hedge, the value of the derivative instrument and its hedge are not perfectly correlated. For example, if the value of a derivative instrument used in a short hedge (such as writing a call option, buying a put option or selling a futures contract) increased by less than the decline in value of the hedged investments, the hedge would not be perfectly correlated. This might occur due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded. The effectiveness of hedges using instruments on indices will depend, in part, on the degree of correlation between price movements in the index and the price movements in the investments being hedged.

(4)

Liquidity Risk. Liquidity risk is the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value. Generally, exchange contracts are very liquid because the exchange clearinghouse is the counterparty of every contract. OTC transactions are less liquid than exchange-traded derivatives since they often can only be closed out with the other party to the transaction. The Fund might be required by applicable regulatory requirements to maintain assets as “cover,” maintain segregated accounts, and/or make margin payments when it takes positions in derivative instruments involving obligations to third parties (i.e., instruments other than purchase options). If the Fund is unable to close out its positions in such instruments, it might be required to continue to maintain such assets or accounts or make such payments until the position expires, matures or is closed out. These requirements might impair the Fund’s ability to sell a security or make an investment at a time when it would otherwise be favorable to do so, or require that the Fund sell a portfolio security at a disadvantageous time. The Fund’s ability to sell or close out a position in an instrument prior to expiration or maturity depends upon the existence of a liquid secondary market or, in the absence of such a market, the ability and willingness of the counterparty to enter into a transaction closing out the position. Due to liquidity risk, there is no assurance that any derivatives position can be sold or closed out at a time and price that is favorable to the Fund.

(5)

Legal Risk. Legal risk is the risk of loss caused by the unenforceability of a party’s obligations under the derivative. While a party seeking price certainty agrees to surrender the potential upside in exchange for downside protection, the party taking the risk is looking for a positive payoff. Despite this voluntary assumption of risk, a counterparty that has lost money in a derivative transaction may try to avoid payment by exploiting various legal uncertainties about certain derivative products.

(6)

Systemic or “Interconnection” Risk. Systemic or “interconnection risk” is the risk that a disruption in the financial markets will cause difficulties for all market participants. In other words, a disruption in one market will spill over into other markets, perhaps creating a chain reaction. Much of the OTC derivatives market takes place among the OTC dealers themselves, thus creating a large interconnected web of financial obligations. This interconnectedness raises the possibility that a default by one large dealer could create losses for other dealers and destabilize the entire market for OTC derivative instruments.

Information Risk

There is typically less publicly available information concerning loans than other types of fixed income investments. As a result, the Fund generally will be dependent on reports and other information provided by the Obligor, either directly or through an Agent, to evaluate the Obligor’s creditworthiness or to determine the Obligor’s compliance with the covenants and other terms of the Loan Agreement. Such reliance may make investments in loans more susceptible to fraud than other types of investments. In addition, because the Advisor may wish to invest in the publicly traded securities of an Obligor, they may not have access to material non-public information regarding the Obligor to which other loan investors have access.

Liquidity Risk

Although the Fund limits its investments in illiquid securities to no more than 15% of its net assets at the time of purchase, securities that are deemed to be liquid at the time of purchase may become illiquid or less liquid. No active trading market may exist for certain securities and certain securities may be subject to restrictions on resale or have a limited secondary market. Certain securities may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. The inability to dispose of certain securities in a timely fashion or at a favorable price could result in losses to the Fund.

Whether or not the securities held by the Fund are listed on a securities exchange, the principal trading market for certain of the securities may be in the OTC market. As a result, the existence of a liquid trading market for such securities may depend on whether dealers will make a market in the securities. There can be no assurance that a market will be made for any of the securities, that any market for such securities will be maintained or that there will be sufficient liquidity of the securities in any markets made. The price at which such securities are held by the Fund will be adversely affected if trading markets for the securities are limited or absent.

Listing Standards Risk

The Fund is required to comply with listing requirements adopted by the Exchange. Non-compliance with such requirements may result in the Fund's shares being delisted by the Exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders.

Market Risk

Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments due to short-term market movements or any longer periods during more prolonged market downturns. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

Health crises caused by the outbreak of infectious diseases or other public health issues, may exacerbate other pre-existing political, social, economic, market and financial risks. The impact of any such events, could negatively affect the global economy, as well as the economies of individual countries or regions, the financial performance of individual companies, sectors and industries, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests and negatively impact the Fund’s investment return. For example, an outbreak of a respiratory disease designated as COVID-19 was first detected in China in December 2019 and subsequently spread internationally. The transmission of COVID-19 and efforts to contain its spread have resulted in international, national and local border closings and other significant travel restrictions and disruptions, significant disruptions to business operations, supply chains and customer activity, event cancellations and restrictions, service cancellations, reductions and other changes, significant challenges in healthcare service preparation and delivery, and quarantines, as well as general concern and uncertainty that has negatively affected the economic environment. These impacts also have caused significant volatility and declines in global financial markets, which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession.

In addition, the operations of the Fund, the Advisor and the Fund’s other service providers may be significantly impacted, or even temporarily or permanently halted, as a result of government quarantine measures, voluntary and precautionary restrictions on travel or meetings and other factors related to a public health emergency, including its potential adverse impact on the health of any such entity’s personnel.

Non-U.S. Securities Risk

An investment in non-U.S. securities involves risks in addition to the usual risks inherent in domestic investments, including currency risk. The value of a non-U.S. security in U.S. dollars tends to decrease when the value of the U.S. dollar rises against the non-U.S. currency in which the security is denominated and tends to increase when the value of the U.S. dollar falls against such currency. Non-U.S. securities are affected by the fact that in many countries there is less publicly available information about issuers than is available in the reports and ratings published about companies in the United States and companies may not be subject to uniform accounting, auditing and financial reporting standards. Other risks inherent in non-U.S. investments may include expropriation; confiscatory taxation; withholding taxes on dividends and interest; less extensive regulation of non-U.S. brokers, securities markets and issuers; diplomatic developments; and political or social instability. Non-U.S. economies may differ favorably or unfavorably from the U.S. economy in various respects, and many non-U.S. securities are less liquid and their prices tend to be more volatile than comparable U.S. securities. From time to time, non-U.S. securities may be difficult to liquidate rapidly without adverse price effects.

Authorization, Custody and Settlement Risk for Non-U.S. Securities

Approval of governmental authorities may be required prior to investing in the securities of companies based in certain frontier countries. Delays in obtaining such an approval would delay investments in the particular country.

Rules adopted under the 1940 Act permit a fund to maintain its non-U.S. securities and cash in the custody of certain eligible non-U.S. banks and securities depositories. Certain banks in foreign countries that are eligible foreign sub-custodians may be recently organized or otherwise lack extensive operating experience. In addition, in certain countries there may be legal restrictions or limitations on the ability of the Fund to recover assets held in custody by a foreign sub-custodian in the event of the bankruptcy of the sub-custodian. Settlement systems in emerging markets may be less well organized than in developed markets. Thus there may be a risk that settlement may be delayed and that cash or securities of the Fund may be in jeopardy because of failures of or defects in the systems. Under the laws of certain countries in which the Fund may invest, the Fund may be required to release local shares before receiving cash payment or may be required to make cash payment prior to receiving local shares.

Certain countries in which the Fund may invest utilize share blocking schemes. Share blocking refers to a practice, in certain foreign markets, where voting rights related to an issuer’s securities are predicated on these securities being blocked from trading at the custodian or sub-custodian level, for a period of time around a shareholder meeting. These restrictions have the effect of prohibiting securities to potentially be voted (or having been voted), from trading within a specified number of days before, and in certain instances, after the shareholder meeting.

Share blocking may prevent the Fund from buying or selling securities for a period of time. During the time that shares are blocked, trades in such securities will not settle. The specific practices may vary by market and the blocking period can last from a day to several weeks, typically terminating on a date established at the discretion of the issuer.

Once blocked, the only manner in which to remove this block would be to withdraw a previously cast vote, or to abstain from voting altogether. The process for having a blocking restriction lifted can be quite onerous, with the particular requirements varying widely by country. In addition, in certain countries, the block cannot be removed.

Share blocking may present operational challenges for the Fund and authorized participants, including the effect that an imposed block would have on pending trades. Pending trades may be caused to fail and could potentially remain unsettled for an extended period of time. Fails may also expose the transfer agent and the Fund to “Buy In” situations in which, if unable to deliver shares after a certain period of time, a counterparty has the right to go to market, purchase a security at the current market price and have any additional expense borne by the Fund or transfer agent.

As a result, the Advisor, on behalf of the Fund, reserves the right to abstain from voting proxies in share blocking proxy markets.

Regulatory Changes

To the extent that legislation or state or federal regulators that regulate certain financial institutions impose additional requirements or restrictions with respect to the ability of such institutions to make loans, particularly in connection with highly leveraged transactions, the availability of loans for investment may be adversely affected. Furthermore, such legislation or regulation could depress the market value of loans held by the Fund.

Risk Factors of Loan Assignments and Participations

Loans are subject to the risks associated with debt obligations in general including interest rate risk, credit risk and market risk. When a loan is acquired from a lender, the risk includes the credit risk associated with the Obligor of the underlying loan. The Fund may incur additional credit risk when the Fund acquires a participation in a loan from another lender because the Fund must assume the risk of insolvency or bankruptcy of the other lender from which the loan was acquired. To the extent that loans involve Obligors in foreign or emerging markets, such loans are subject to the risks associated with foreign investments or investments in emerging markets in general.

Securities Lending Risk

Securities lending involves exposure to certain risks, including counterparty risk, collateral risk and operational risk. Counterparty risk is the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, a First Trust Fund engaged in securities lending transactions may suffer a loss and there may be a delay in recovering the lent securities. Any delay in the return of securities on loan may restrict the ability of the Fund to meet delivery or payment obligations. Collateral risk is the risk that the collateral received may be realized at a value lower than the value of the securities lent, whether due to inaccurate pricing of the collateral, adverse market movements in the value of the collateral, intra-day increases in the value of the securities lent, a deterioration in the credit rating of the collateral issuer, or the illiquidity of the market in which the collateral is traded. Securities lending also entails operational risks, such as settlement failures or delays in the settlement of instructions. Such failures or delays may restrict the ability of the Fund to meet delivery or payment obligations. Lastly, securities lending activities may result in adverse tax consequences for the Fund and its shareholders. For instance, substitute payments for dividends received by the Fund for securities loaned out by the Fund will not be considered qualified dividend income. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan.

Tax Law Change Risk

Changes in tax laws or regulations, or interpretations thereof in the future, could adversely affect the Fund or the assets in which it invests. Any such changes could negatively impact the Fund and its shareholders.

Volatility Risk

The market price and net asset value of the Fund’s shares and the Fund’s yield will change daily. There may be instances when the Fund will experience large in-flows and out-flows, which will significantly alter the Fund’s size. At times, these fluctuations may negatively impact the Fund’s yield, result in increased transaction costs for the Fund and contribute to the overall volatility of the Fund. The risk will be more prevalent when the Fund is smaller in size, such as during the Fund’s invest-up period. An investor may lose money by investing in this Fund because this Fund is not a money market fund and may experience significant fluctuations in its net asset value.

Management of the Fund

Trustees and Officers

The general supervision of the duties performed for the Fund under the investment management agreement is the responsibility of the Board of Trustees. There are five Trustees of the Trust, one of whom is an “interested person” (as the term is defined in the 1940 Act) and four of whom are Trustees who are not officers or employees of First Trust or any of its affiliates (“Independent Trustees”). The Trustees set broad policies for the Fund, choose the Trust’s officers and hire the Trust’s investment advisor. The officers of the Trust manage its day-to-day operations and are responsible to the Board of Trustees. The following is a list of the Trustees and executive officers of the Trust and a statement of their present positions and principal occupations during the past five years, the number of portfolios each Trustee oversees and the other directorships they have held during the past five years, if applicable. Each Trustee has been elected for an indefinite term. The officers of the Trust serve indefinite terms. Each Trustee, except for James A. Bowen, is an Independent Trustee. Mr. Bowen is deemed an “interested person” (as that term is defined in the 1940 Act) (“Interested Trustee”) of the Trust due to his position as Chief Executive Officer of First Trust, investment advisor to the Fund. The following table identifies the Trustees and Officers of the Trust.

Mr. Bowen is deemed an “interested person” of the Trust due to his position as Chief Executive Officer of First Trust, investment advisor of the Fund.

Unitary Board Leadership Structure

Each Trustee serves as a trustee of all open-end and closed-end funds in the First Trust Fund Complex (as defined below), which is known as a “unitary” board leadership structure. Each Trustee currently serves as a trustee of First Trust Series Fund and First Trust Variable Insurance Trust, open-end funds with eight portfolios advised by First Trust; First Trust Senior Floating Rate Income Fund II, Macquarie/First Trust Global Infrastructure/Utilities Dividend & Income Fund, First Trust Energy Income and Growth Fund, First Trust Enhanced Equity Income Fund, First Trust/Aberdeen Global Opportunity Income Fund, First Trust Mortgage Income Fund, First Trust/Aberdeen Emerging Opportunity Fund, First Trust Specialty Finance and Financial Opportunities Fund, First Trust High Income Long/Short Fund, First Trust Energy Infrastructure Fund, First Trust MLP and Energy Income Fund, First Trust Intermediate Duration Preferred & Income Fund, First Trust Dynamic Europe Equity Income Fund, First Trust New Opportunities MLP & Energy Fund, First Trust Senior Floating Rate 2022 Target Term Fund and First Trust High Yield Opportunities 2027 Term Fund, closed-end funds advised by First Trust; and First Trust Exchange-Traded Fund, First Trust Exchange-Traded Fund II, First Trust Exchange-Traded Fund III, First Trust Exchange-Traded Fund IV, First Trust Exchange-Traded Fund V, First Trust Exchange-Traded Fund VI, First Trust Exchange-Traded Fund VII, First Trust Exchange-Traded Fund VIII, First Trust Exchange-Traded AlphaDEX® Fund and First Trust Exchange-Traded AlphaDEX® Fund II, exchange-traded funds with 172 portfolios advised by First Trust (each a “First Trust Fund” and collectively, the “First Trust Fund Complex”). None of the Trustees who are not “interested persons” of the Trust, nor any of their immediate family members, has ever been a director, officer or employee of, or consultant to, First Trust, First Trust Portfolios L.P. or their affiliates.

The management of the Fund, including general supervision of the duties performed for the Fund under the investment management agreement between the Trust, on behalf of the Fund, and the Advisor, is the responsibility of the Board of Trustees. The Trustees set broad policies for the Fund, choose the Trust’s officers and hire the Fund's investment advisor, sub-advisors and other service providers. The officers of the Trust manage the day-to-day operations and are responsible to the Board. The Board is composed of four Independent Trustees and one Interested Trustee. The Interested Trustee, James A. Bowen, serves as the Chairman of the Board for each fund in the First Trust Fund Complex.

The same five persons serve as Trustees on the Board and on the Boards of all other First Trust Funds. The unitary board structure was adopted for the First Trust Funds because of the efficiencies it achieves with respect to the governance and oversight of the First Trust Funds. Each First Trust Fund is subject to the rules and regulations of the 1940 Act (and other applicable securities laws), which means that many of the First Trust Funds face similar issues with respect to certain of their fundamental activities, including risk management, portfolio liquidity, portfolio valuation and financial reporting. Because of the similar and often overlapping issues facing the First Trust Funds, including among the First Trust exchange-traded funds, the Board of the First Trust Funds believes that maintaining a unitary board structure promotes efficiency and consistency in the governance and oversight of all First Trust Funds and reduces the costs, administrative burdens and possible conflicts that may result from having multiple boards. In adopting a unitary board structure, the Trustees seek to provide effective governance through establishing a board the overall composition of which will, as a body, possess the appropriate skills, diversity, independence and experience to oversee the Fund's business.

Annually, the Board reviews its governance structure and the committee structures, their performance and functions, and it reviews any processes that would enhance Board governance over the Fund's business. The Board has determined that its leadership structure, including the unitary board and committee structure, is appropriate based on the characteristics of the funds it serves and the characteristics of the First Trust Fund Complex as a whole.

In order to streamline communication between the Advisor and the Independent Trustees and create certain efficiencies, the Board has a Lead Independent Trustee who is responsible for: (i) coordinating activities of the Independent Trustees; (ii) working with the Advisor, Fund counsel and the independent legal counsel to the Independent Trustees to determine the agenda for Board meetings; (iii) serving as the principal contact for and facilitating communication between the Independent Trustees and the Fund's service providers, particularly the Advisor; and (iv) any other duties that the Independent Trustees may delegate to the Lead Independent Trustee. The Lead Independent Trustee is selected by the Independent Trustees and serves a three-year term or until his or her successor is selected.

meetings (other than meetings of the Executive Committee and Dividend Committee). Generally, the Board acts by majority vote of all the Trustees, including a majority vote of the Independent Trustees if required by applicable law.

The four Committee Chairmen and the Lead Independent Trustee rotate every three years in serving as Chairman of the Audit Committee, the Nominating and Governance Committee, the Valuation Committee or the Dividend Committee, or as Lead Independent Trustee. The Lead Independent Trustee and immediately preceding Lead Independent Trustee also serve on the Executive Committee with the Interested Trustee.

The five standing committees of the First Trust Fund Complex are: the Executive Committee, the Nominating and Governance Committee, the Valuation Committee, the Audit Committee and the Dividend Committee. The Executive Committee, which meets between Board meetings, is authorized to exercise all powers of and to act in the place of the Board of Trustees to the extent permitted by the Trust’s Declaration of Trust and By Laws. Mr. Nielson, Mr. Bowen and Dr. Erickson are members of the Executive Committee. During the last fiscal year, the Executive Committee held twelve meetings.

The Nominating and Governance Committee is responsible for appointing and nominating non-interested persons to the Board of Trustees. Messrs. Erickson, Kadlec, Keith and Nielson are members of the Nominating and Governance Committee. If there is no vacancy on the Board of Trustees, the Board will not actively seek recommendations from other parties, including shareholders. The Board of Trustees adopted a mandatory retirement age of 75 for Trustees, beyond which age Trustees are ineligible to serve. The Committee will not consider new trustee candidates who are 72 years of age or older or will turn 72 years old during the initial term. When a vacancy on the Board of Trustees occurs or is anticipated to occur and nominations are sought to fill such vacancy, the Nominating and Governance Committee may seek nominations from those sources it deems appropriate in its discretion, including shareholders of the Fund. To submit a recommendation for nomination as a candidate for a position on the Board of Trustees, shareholders of the Fund should mail such recommendation to W. Scott Jardine, Secretary, at the Trust’s address, 120 East Liberty Drive, Suite 400, Wheaton, Illinois 60187. Such recommendation shall include the following information: (i) evidence of Fund ownership of the person or entity recommending the candidate (if a Fund shareholder); (ii) a full description of the proposed candidate’s background, including education, experience, current employment and date of birth; (iii) names and addresses of at least three professional references for the candidate; (iv) information as to whether the candidate is an “interested person” in relation to the Fund, as such term is defined in the 1940 Act, and such other information that may be considered to impair the candidate’s independence; and (v) any other information that may be helpful to the Committee in evaluating the candidate. If a recommendation is received with satisfactorily completed information regarding a candidate during a time when a vacancy exists on the Board or during such other time as the Nominating and Governance Committee is accepting recommendations, the recommendation will be forwarded to the Chairman of the Nominating and Governance Committee and to counsel to the Independent Trustees. During the last fiscal year, the Nominating and Governance Committee held five meetings.

The Valuation Committee is responsible for the oversight of the valuation procedures of the Fund (the "Valuation Procedures"), for determining the fair value of the Fund's securities or other assets under certain circumstances as described in the Valuation Procedures and for evaluating the performance of any pricing service for the Fund. Messrs. Erickson, Kadlec, Keith and Nielson are members of the Valuation Committee. During the last fiscal year, the Valuation Committee held four meetings.

The Audit Committee is responsible for overseeing the Fund’s accounting and financial reporting process, the system of internal controls and audit process and for evaluating and appointing independent auditors (subject also to Board approval). Messrs. Erickson, Kadlec, Keith and Nielson serve on the Audit Committee. During the last fiscal year, the Audit Committee held four meetings.

The Dividend Committee is responsible for assisting the Board in, or assuming the authority and power of the Board with respect to, the declaration and setting of the Fund's dividends. Messrs. Erickson and Nielson serve on the Dividend Committee. During the last fiscal year, the Dividend Committee did not hold any meetings.

Executive Officers

The executive officers of the Trust hold the same positions with each fund in the First Trust Fund Complex (representing 196 portfolios) as they hold with the Trust, except Mr. Ueland who is an executive officer of only the ETFs advised by First Trust and Mr. Testin who is an executive officer of only the ETFs and open-end funds advised by First Trust.

Risk Oversight

As part of the general oversight of the Fund, the Board is involved in the risk oversight of the Fund. The Board has adopted and periodically reviews policies and procedures designed to address the Fund’s risks. Oversight of investment and compliance risk is performed primarily at the Board level in conjunction with the Advisor’s investment oversight group and the Trust’s Chief Compliance Officer (“CCO”). Oversight of other risks also occurs at the committee level. The Advisor’s investment oversight group reports to the Board at quarterly meetings regarding, among other things, Fund performance and the various drivers of such performance. The Board reviews reports on the Fund's and the service providers’ compliance policies and procedures at each quarterly Board meeting and receives an annual report from the CCO regarding the operations of the Fund's and the service providers’ compliance programs. In addition, the Independent Trustees meet privately each quarter with the CCO. The Audit Committee reviews with the Advisor the Fund’s major financial risk exposures and the steps the Advisor has taken to monitor and control these exposures, including the Fund’s risk assessment and risk management policies and guidelines. The Audit Committee also, as appropriate, reviews in a general manner the processes other Board committees have in place with respect to risk assessment and risk management. The Nominating and Governance Committee monitors all matters related to the corporate governance of the Trust. The Valuation Committee monitors valuation risk and compliance with the Fund's Valuation Procedures and oversees the pricing services and actions by the Advisor’s Pricing Committee with respect to the valuation of portfolio securities.

Not all risks that may affect the Fund can be identified nor can controls be developed to eliminate or mitigate their occurrence or effects. It may not be practical or cost effective to eliminate or mitigate certain risks, the processes and controls employed to address certain risks may be limited in their effectiveness, and some risks are simply beyond the reasonable control of the Fund or the Advisor or other service providers. For instance, as the use of Internet technology has become more prevalent, the Fund and its service providers have become more susceptible to potential operational risks through breaches in cyber security (generally, intentional and unintentional events that may cause the Fund or a service provider to lose proprietary information, suffer data corruption or lose operational capacity). There can be no guarantee that any risk management systems established by the Fund, its service providers, or issuers of the securities in which the Fund invests to reduce cyber security risks will succeed, and the Fund cannot control such systems put in place by service providers, issuers or other third parties whose operations may affect the Fund and/or its shareholders. Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve the Fund's goals. As a result of the foregoing and other factors, the Fund's ability to manage risk is subject to substantial limitations.

Board Diversification and Trustee Qualifications

As described above, the Nominating and Governance Committee of the Board oversees matters related to the selection and nomination of Trustees. The Nominating and Governance Committee seeks to establish an effective Board with an appropriate range of skills and diversity, including, as appropriate, differences in background, professional experience, education, vocation, and other individual characteristics and traits in the aggregate. Each Trustee must meet certain basic requirements, including relevant skills and experience, time availability and, if qualifying as an Independent Trustee, independence from the Advisor and any sub-advisors, underwriters or other service providers, including any affiliates of these entities.

Listed below for each current Trustee are the experiences, qualifications and attributes that led to the conclusion, as of the date of this SAI, that each current Trustee should serve as a Trustee in light of the Trust’s business and structure.

As of December 31, 2020, the officers and Trustees, in the aggregate, owned less than 1% of the shares of the Fund.

The table set forth in Exhibit A shows the percentage ownership of each shareholder or “group” (as that term is used in Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) who, based on the securities position listing reports as of January 31, 2020, owned of record, or is known by the Trust to have owned of record or beneficially, 5% or more of the shares of the Fund (the “Principal Holders”). A control person is one who owns, either directly or indirectly, more than 25% of the voting securities of the Fund or acknowledges the existence of control. A party that controls the Fund may be able to significantly influence the outcome of any item presented to shareholders for approval.

Investment Advisor. First Trust, 120 East Liberty Drive, Suite 400, Wheaton, Illinois 60187, is the investment advisor to the Fund. First Trust is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. Grace Partners of DuPage L.P. is a limited partnership with one general partner, The Charger Corporation, and a number of limited partners. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, the Chief Executive Officer of First Trust. First Trust discharges its responsibilities to the Fund subject to the policies of the Board of Trustees.

First Trust provides investment tools and portfolios for advisors and investors. First Trust is committed to theoretically sound portfolio construction and empirically verifiable investment management approaches. Its asset management philosophy and investment discipline are deeply rooted in the application of intuitive factor analysis and model implementation to enhance investment decisions.

and administrative services, and permits any of its officers or employees to serve without compensation as Trustees or officers of the Trust if elected to such positions.

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the “Investment Management Agreement”), First Trust manages the investment of the Fund’s assets and is responsible for paying all expenses of the Fund, excluding the fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions, acquired fund fees and expenses, if any, and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.45% of its average daily net assets.

Pursuant to a contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the portion of the management fees earned by First Trust from the Fund for assets invested in other investment companies advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Trust’s Board of Trustees or (ii) upon the termination of the Fund’s management agreement with First Trust, however, it is expected to remain in place for no less than one year from the date of this SAI. Pursuant to two separate contractual agreements, First Trust has agreed to waive management fees of 0.05% and 0.15% of average daily net assets until March 1, 2022. These waiver agreements may be terminated by action of the Board of Trustees, at any time upon 60 days' written notice by the Trust on behalf of the Fund or by First Trust, only after March 1, 2022. First Trust has committed to the fee waivers to respond to the current low interest rate environment and expects that the fee waivers will be appropriate until long term yields increase. First Trust anticipates that if the average yield over the prior 30-day period on the current one year U.S. Treasury Bond continues to exceed 1.50%, one or both fee waivers may not be continued past March 1, 2022.

Under the Investment Management Agreement, First Trust shall not be liable for any loss sustained by reason of the purchase, sale or retention of any security, whether or not such purchase, sale or retention shall have been based upon the investigation and research made by any other individual, firm or corporation, if such recommendation shall have been selected with due care and in good faith, except loss resulting from willful misfeasance, bad faith, or gross negligence on the part of First Trust in the performance of its obligations and duties, or by reason of its reckless disregard of its obligations and duties. The Investment Management Agreement terminates automatically upon assignment and is terminable at any time without penalty as to the Fund by the Board of Trustees, including a majority of the Independent Trustees, or by vote of the holders of a majority of the Fund’s outstanding voting securities on 60 days’ written notice to First Trust, or by First Trust on 60 days’ written notice to the Fund.

The following table sets forth the unitary fee (net of fee waivers, where applicable) paid by the Fund to First Trust and the fees waived, by First Trust, where applicable, for the specified periods.

Amount of Unitary Fees			Amount of Fees Waived and Expenses Reimbursed By First Trust
Fiscal Year Ended October 31,			Fiscal Year Ended October 31,
2020	2019	2018	2020	2019	2018
$19,007,284	$16,591,310	$6,275,411	$3,485,866	$2,775,527	$2,377,599

Portfolio Managers. The portfolio managers are primarily and jointly responsible for the day-to-day management of the Fund. There are currently five portfolio managers, as follows:

Name	Position with First Trust	Length of Service with First Trust	Principal Occupation During Past Five Years
Todd Larson	Vice President and Portfolio Manager	Since 2007	Senior Vice President, Portfolio Manager, First Trust Advisors L.P. and First Trust Portfolios L.P.
Eric R. Maisel	Vice President and Portfolio Manager	Since 2008	Senior Vice President and Portfolio Manager, First Trust Advisors L.P. and First Trust Portfolios L.P.
James Snyder	Senior Vice President and Portfolio Manager	Since 2013	Senior Vice President and Portfolio Manager, First Trust Advisors L.P. (2019 to present); Vice President and Portfolio Manager (2013 - 2019), First Trust Advisors L.P. and First Trust Portfolios L.P.; Senior Portfolio Manager, Fort Sheridan Advisors (2003 - 2013)

Name	Position with First Trust	Length of Service with First Trust	Principal Occupation During Past Five Years
Jeremiah Charles	Senior Vice President and Portfolio Manager	Since 2013	Senior Vice President and Portfolio Manager, First Trust Advisors L.P. (2019 to present); Vice President and Portfolio Manager (2013 - 2019), First Trust Advisors L.P. and First Trust Portfolios L.P.; Vice President of Mortgage Product Sales, CRT Capital (2011 - 2013)

Todd Larson, CFA: As head of First Trust’s Fixed Income Group, Mr. Larson is responsible for implementing fixed income investment strategies for First Trust’s institutional clients.

Eric Maisel: Mr. Maisel serves as a Portfolio Manager for First Trust’s Fixed Income Group.

James Snyder: Mr. Snyder serves as a Portfolio Manager for the First Trust Securitized Products Group.

Jeremiah Charles: Mr. Charles serves as a Portfolio Manager for the First Trust Securitized Products Group.

As of October 31, 2020, Mr. Larson beneficially owned shares of the Fund in the amount of over $100,000, Mr. Charles beneficially owned shares of the Fund in the amount of $10,001 - $50,000, Mr. Maisel owned shares of the Fund in the amount of $1 - $10,000 and Mr. Snyder did not beneficially own any shares of the Fund.

Compensation. The compensation structure for each portfolio manager is based upon a fixed salary as well as a discretionary bonus determined by the management of First Trust. Salaries are determined by management and are based upon an individual’s position and overall value to the firm. Bonuses are also determined by management and are based upon an individual’s overall contribution to the success of the firm and the profitability of the firm. Salaries and bonuses for the portfolio managers are not based upon criteria such as performance of the Fund or the value of assets included in the Fund’s portfolio.

Accounts Managed by Portfolio Managers

The portfolio managers manage the investment vehicles (other than the Fund) with the number of accounts and assets, as of the fiscal year ended October 31, 2020, set forth in the table below:

Portfolio Manager	Registered Investment Companies Number of Accounts ($ Assets)	Other Pooled Investment Vehicles Number of Accounts ($ Assets)	Other Accounts Number of Accounts ($ Assets)
Todd Larson	6 ($482,459,099)	N/A	10 ($4,940,180)
Eric R. Maisel	2 ($410,167,684)	N/A	10 ($4,940,180)
James Snyder	5 ($6,523,307,817)	N/A	N/A
Jeremiah Charles	5 ($6,523,307,817)	N/A	N/A

Conflicts. None of the accounts managed by the portfolio managers pays an advisory fee that is based upon the performance of the account. In addition, First Trust believes that there are no material conflicts of interest that may arise in connection with the portfolio managers’ management of the Fund’s investments and the investments of the other accounts managed by the portfolio managers. However, because the investment strategy of the Fund and the investment strategies of many of the other accounts managed by the portfolio managers are based on fairly mechanical investment processes, the portfolio managers may recommend that certain clients sell and other clients buy a given security at the same time. In addition, because the investment strategies of the Fund and other accounts managed by the portfolio managers generally result in the clients investing in readily available securities, First Trust believes that there should not be material conflicts in the allocation of investment opportunities between the Fund and other accounts managed by the portfolio managers.

Brokerage Allocations

net price without regard to the mix between purchase or sale price and commission, if any. Purchases may be made from underwriters, dealers and, on occasion, the issuers. Commissions will be paid on the Fund’s futures and options transactions, if any. The purchase price of portfolio securities purchased from an underwriter or dealer may include underwriting commissions and dealer spreads. The Fund may pay markups on principal transactions. In selecting broker-dealers and in negotiating commissions, First Trust considers, among other things, the firm’s reliability, the quality of its execution services on a continuing basis and its financial condition. Fund portfolio transactions may be effected with broker-dealers who have assisted investors in the purchase of shares.

Section 28(e) of the 1934 Act permits an investment advisor, under certain circumstances, to cause an account to pay a broker or dealer who supplies brokerage and research services a commission for effecting a transaction in excess of the amount of commission another broker or dealer would have charged for effecting the transaction. Brokerage and research services include (a) furnishing advice as to the value of securities, the advisability of investing, purchasing or selling securities, and the availability of securities or purchasers or sellers of securities; (b) furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy and the performance of accounts; and (c) effecting securities transactions and performing functions incidental thereto (such as clearance, settlement and custody). Such brokerage and research services are often referred to as “soft dollars.” First Trust has advised the Board of Trustees that it does not currently intend to use soft dollars.

Notwithstanding the foregoing, in selecting brokers, First Trust may in the future consider investment and market information and other research, such as economic, securities and performance measurement research, provided by such brokers, and the quality and reliability of brokerage services, including execution capability, performance and financial responsibility. Accordingly, the commissions charged by any such broker may be greater than the amount another firm might charge if First Trust determines in good faith that the amount of such commissions is reasonable in relation to the value of the research information and brokerage services provided by such broker to First Trust or the Trust. In addition, First Trust must determine that the research information received in this manner provides the Fund with benefits by supplementing the research otherwise available to the Fund. The Investment Management Agreement provides that such higher commissions will not be paid by the Fund unless the Advisor determines in good faith that the amount is reasonable in relation to the services provided. The investment advisory fees paid by the Fund to First Trust under the Investment Management Agreement would not be reduced as a result of receipt by First Trust of research services.

First Trust places portfolio transactions for other advisory accounts advised by it, and research services furnished by firms through which the Fund effects its securities transactions may be used by First Trust in servicing all of its accounts; not all of such services may be used by First Trust in connection with the Fund. First Trust believes it is not possible to measure separately the benefits from research services to each of the accounts (including the Fund) advised by it. Because the volume and nature of the trading activities of the accounts are not uniform, the amount of commissions in excess of those charged by another broker paid by each account for brokerage and research services will vary. However, First Trust believes such costs to the Fund will not be disproportionate to the benefits received by the Fund on a continuing basis. First Trust seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell securities by the Fund and another advisory account. In some cases, this procedure could have an adverse effect on the price or the amount of securities available to the Fund. In making such allocations between the Fund and other advisory accounts, the main factors considered by First Trust are the respective investment objectives, the relative size of portfolio holding of the same or comparable securities, the availability of cash for investment and the size of investment commitments generally held.

Brokerage Commissions

The following table sets forth the aggregate amount of brokerage commissions paid by the Fund for the specified periods. Significant variations in the amount the Fund paid in brokerage commissions from year-to-year are generally the result of fluctuations in the size of the Fund or changes to the Fund’s portfolio holdings.

During the last fiscal year, First Trust Enhanced Short Maturity ETF held securities of Barclays Capital, Inc., BOFA Securities, Inc., CitiGroup Global Markets, Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Mizuho Securities USA LLC, RBC

Capital Markets LLC and Wells Fargo Securities, LLC, each a regular broker or dealer of the Fund as defined in Rule 10b-1 under the 1940 Act. As of October 31, 2020, the Fund’s investment in each was 0.21%, 1.33%, 1.21%, 0.94%, 1.13%, 0.29%, 0.50% and 1.00% of the Fund’s net assets, respectively.

Administrator, Fund Accounting Agent, Custodian, Transfer Agent, Distributor and Exchange

Administrator and Fund Accounting Agent. The Fund has appointed The Bank of New York Mellon Corporation ("BNYM"), located at 240 Greenwich Street, New York, New York 10286, to serve as the Fund’s administrator and provide the Fund with accounting services pursuant to a fund administration and accounting agreement (the “Administration and Accounting Agreement”). Under the Administration and Accounting Agreement, BNYM is obligated, on a continuous basis, to provide such administrative services as the Board reasonably deems necessary for the proper administration of the Trust and the Fund. BNYM generally will assist in many aspects of the Trust’s and the Fund’s operations, including accounting, bookkeeping and record keeping services (including, without limitation, the maintenance of such books and records as are required under the 1940 Act and the rules thereunder, except as maintained by other service providers), assist in preparing reports to shareholders or investors, prepare and file tax returns, supply financial information and supporting data for reports to and filings with the SEC and various state Blue Sky authorities and supply supporting documentation for meetings of the Board.

Custodian. The Trust has appointed BNYM to serve as the Fund's custodian pursuant to a custody agreement (the “Custody Agreement”). Pursuant to the terms of the Custody Agreement, BNYM is generally responsible for the safekeeping of the Fund's assets and performing various other administrative duties set forth in the agreement.

Transfer Agent. The Trust has appointed BNYM to serve as the Fund's transfer agent and dividend disbursing agent pursuant to a transfer agency and service agreement (the “Transfer Agency Agreement”). Pursuant to the terms of the Transfer Agency Agreement, BNYM is responsible for performing and facilitating the purchases and redemptions of Creation Unit Aggregations, as well as performing other customary services of a transfer agent and dividend disbursing agent.

As set forth in the Administration and Accounting Agreement, Custody Agreement and Transfer Agency Agreement, the Trust, on behalf of the Fund, has agreed to indemnify and hold harmless BNYM from certain costs, expenses, damages, liabilities or claims which are sustained or incurred or which may be asserted against BNYM, provided that such costs, expenses, damages, liabilities and claims did not result from BNYM’s own negligence or willful misconduct.

Distributor. First Trust Portfolios L.P., an affiliate of First Trust, is the distributor (“FTP” or the “Distributor”) and principal underwriter of the shares of the Fund. Its principal address is 120 East Liberty Drive, Suite 400, Wheaton, Illinois 60187. The Distributor has entered into a Distribution Agreement with the Trust pursuant to which it distributes Fund shares. Shares are continuously offered for sale by the Fund through the Distributor only in Creation Unit Aggregations, as described in the Prospectus and below under the heading “Creation and Redemption of Creation Unit Aggregations.”

For the fiscal years ended October 31, 2018, October 31, 2019 and October 31, 2020, there were no underwriting commissions with respect to the sale of Fund shares, and FTP did not receive compensation on redemptions for the Fund for those periods.

12b -1 Plan. The Trust has adopted a Plan of Distribution pursuant to Rule 12b-1 under the 1940 Act (the “Plan” ) pursuant to which the Fund may reimburse the Distributor up to a maximum annual rate of 0.25% of its average daily net assets.

Under the Plan and as required by Rule 12b-1, the Trustees will receive and review after the end of each calendar quarter a written report provided by the Distributor of the amounts expended under the Plan and the purpose for which such expenditures were made. With the exception of the Distributor and its affiliates, no “interested person” of the Trust (as that term is defined in the 1940 Act) and no Trustee of the Trust has a direct or indirect financial interest in the operation of the Plan or any related agreement.

No fee is currently paid by the Fund under the Plan, and pursuant to a contractual agreement, the Fund will not pay 12b-1 fees any time before March 31, 2022.

Aggregations. Fund shares in less than Creation Unit Aggregations are not distributed by the Distributor. The Distributor will deliver the Prospectus and, upon request, this SAI to persons purchasing Creation Unit Aggregations and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority (“FINRA”).

The Distribution Agreement provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ written notice by the Trust to the Distributor (i) by vote of a majority of the Independent Trustees; or (ii) by vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with participants that utilize the facilities of the Depository Trust Company (the “DTC Participants”), which have international, operational, capabilities and place orders for Creation Unit Aggregations of Fund shares. Participating Parties (which are participants in the Continuous Net Settlement System of the National Securities Clearing Corporation) shall be DTC Participants.

Exchange. The only relationship that the Exchange has with First Trust or the Distributor of the Fund in connection with the Fund is that the Exchange lists the shares of the Fund and disseminates the intra-day portfolio values that are calculated by the IPV calculator pursuant to its listing agreement with the Trust. The Exchange is not responsible for and has not participated in the determination of pricing or the timing of the issuance or sale of the shares of the Fund or in the determination or calculation of the asset value of the Fund. The Exchange has no obligation or liability in connection with the administration, marketing or trading of the Fund.

Additional Payments to Financial Intermediaries

First Trust or its affiliates may from time to time make payments, out of their own resources, to certain financial intermediaries that sell shares of First Trust mutual funds and ETFs (“First Trust Funds”) to promote the sales and retention of Fund shares by those firms and their customers. The amounts of these payments vary by intermediary. The level of payments that First Trust is willing to provide to a particular intermediary may be affected by, among other factors, (i) the firm’s total assets or Fund shares held in and recent net investments into First Trust Funds, (ii) the value of the assets invested in the First Trust Funds by the intermediary’s customers, (iii) redemption rates, (iv) its ability to attract and retain assets, (v) the intermediary’s reputation in the industry, (vi) the level and/or type of marketing assistance and educational activities provided by the intermediary, (vii) the firm’s level of participation in First Trust Funds’ sales and marketing programs, (viii) the firm’s compensation program for its registered representatives who sell Fund shares and provide services to Fund shareholders, and (ix) the asset class of the First Trust Funds for which these payments are provided. Such payments are generally asset-based but also may include the payment of a lump sum.

First Trust may also make payments to certain intermediaries for certain administrative services and shareholder processing services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement. All fees payable by First Trust under this category of services may be charged back to the Fund, subject to approval by the Board.

First Trust and/or its affiliates may make payments, out of its own assets, to those firms as compensation and/or reimbursement for marketing support and/or program servicing to selected intermediaries that are registered as holders or dealers of record for accounts invested in one or more of the First Trust Funds or that make First Trust Fund shares available through certain selected Fund no-transaction fee institutional platforms and fee-based wrap programs at certain financial intermediaries. Program servicing payments typically apply to employee benefit plans, such as retirement plans, or fee-based advisory programs but may apply to retail sales and assets in certain situations. The payments are based on such factors as the type and nature of services or support furnished by the intermediary and are generally asset based. Services for which an intermediary receives marketing support payments may include, but are not limited to, business planning assistance, advertising, educating the intermediary’s personnel about First Trust Funds in connection with shareholder financial planning needs, placement on the intermediary’s preferred or recommended fund list, and access to sales meetings, sales representatives and management representatives of the intermediary. In addition, intermediaries may be compensated for enabling representatives of First Trust and/or its affiliates to participate in and/or present at conferences or seminars, sales or training programs for invited registered representatives and other employees, client and investor events and other events sponsored by the intermediary. Services for which an intermediary receives program servicing payments typically include, but are not limited to, record keeping, reporting or transaction processing and shareholder communications and other account administration services, but may also include services rendered in connection with Fund/investment selection and monitoring, employee enrollment and education, plan balance rollover or separation, or other similar services. An intermediary may perform program services itself or may arrange with a third party to perform program services. These payments, if any, are in addition to the service fee and any applicable omnibus sub-accounting fees paid to these firms with respect to these services by the First Trust Funds out of Fund assets.

From time to time, First Trust and/or its affiliates, at its expense, may provide other compensation to intermediaries that sell or arrange for the sale of shares of the First Trust Funds, which may be in addition to marketing support and program servicing payments described above. For example, First Trust and/or its affiliates may: (i) compensate intermediaries for National Securities Clearing Corporation networking system services (e.g., shareholder communication, account statements, trade confirmations and tax reporting) on an asset-based or per-account basis; (ii) compensate intermediaries for providing Fund shareholder trading information; (iii) make one time or periodic payments to reimburse selected intermediaries for items such as ticket charges (i.e., fees that an intermediary charges its representatives for effecting transactions in Fund shares) or exchange order, operational charges (e.g., fees that an intermediary charges for establishing the Fund on its trading system), and literature printing and/or distribution costs; (iv) at the direction of a retirement plan’s sponsor, reimburse or pay direct expenses of an employee benefit plan that would otherwise be payable by the plan; and (v) provide payments to broker-dealers to help defray their technology or infrastructure costs.

When not provided for in a marketing support or program servicing agreement, First Trust and/ or its affiliates may also pay intermediaries for enabling First Trust and/or its affiliates to participate in and/or present at conferences or seminars, sales or training programs for invited registered representatives and other intermediary employees, client and investor events and other intermediary-sponsored events, and for travel expenses, including lodging incurred by registered representatives and other employees in connection with prospecting, asset retention and due diligence trips. These payments, if any, may vary depending upon the nature of the event. First Trust and/or its affiliates make payments for such events as it deems appropriate, subject to its internal guidelines and applicable law.

First Trust and/or its affiliates occasionally sponsor due diligence meetings for registered representatives during which they receive updates on various First Trust Funds and are afforded the opportunity to speak with portfolio managers. Although invitations to these meetings are not conditioned on selling a specific number of shares, those who have shown an interest in First Trust Funds are more likely to be considered. To the extent permitted by their firm’s policies and procedures, all or a portion of registered representatives’ expenses in attending these meetings may be covered by First Trust and/or its affiliates.

The amounts of payments referenced above made by First Trust and/or its affiliates could be significant and may create an incentive for an intermediary or its representatives to recommend or offer shares of the First Trust Funds to its customers. The intermediary may elevate the prominence or profile of the First Trust Funds within the intermediary’s organization by, for example, placing the First Trust Funds on a list of preferred or recommended funds and/or granting First Trust and/or its affiliates preferential or enhanced opportunities to promote the First Trust Funds in various ways within the intermediary’s organization. These payments are made pursuant to negotiated agreements with intermediaries. The payments do not change the price paid by investors for the purchase of a share or the amount the Fund will receive as proceeds from such sales. Furthermore, many of these payments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus because they are not paid by the Fund. The types of payments described herein are not mutually exclusive, and a single intermediary may receive some or all types of payments as described.

Other compensation may be offered to the extent not prohibited by state laws or any self-regulatory agency, such as FINRA. Investors can ask their intermediaries for information about any payments they receive from First Trust and/or its affiliates and the services it provides for those payments. Investors may wish to take intermediary payment arrangements into account when considering and evaluating any recommendations relating to Fund shares.

Additional Information

Book Entry Only System. The following information supplements and should be read in conjunction with the Prospectus.

DTC Acts as Securities Depository for Fund Shares. Shares of the Fund are represented by securities registered in the name of The Depository Trust Company (“DTC”) or its nominee, Cede & Co., and deposited with, or on behalf of, DTC.

DTC, a limited-purpose trust company, was created to hold securities of its participants (the “DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities, certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the New York Stock Exchange (the “NYSE”) and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (the “Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase and sale of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to a letter agreement between DTC and the Trust, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form and number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participants a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Fund distributions shall be made to DTC or its nominee, as the registered holder of all Fund shares. DTC or its nominee, upon receipt of any such distributions, shall immediately credit DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

DTC may decide to discontinue providing its service with respect to shares at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Policy Regarding Investment in Other Investment Companies. The Fund will not rely on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act to invest in other investment companies.

AIFM Directive Disclosures

Background. The AIFM Directive is a European Union (“EU”) directive which regulates the management and marketing of funds within the EEA. The AIFM Directive distinguishes between EU and non-EU funds and EU and non-EU fund managers and different obligations apply under the AIFM Directive depending on where the fund is based and where the manager is based. Certain disclosure, transparency and reporting obligations are imposed on non-EU fund managers wishing to market funds to investors in the EEA. There are additional requirements imposed on EU fund managers, which do not currently apply to First Trust.

To the extent not already disclosed to you prior to your investment in the Fund, the purpose of this section of the SAI is to satisfy the disclosures which are required to be provided to you under the AIFM Directive.

Overview of the Fund and the Service Providers. The Fund is non-EU AIFs (“AIF” means an alternative investment fund for the purposes of the AIFM Directive).

First Trust Advisors L.P. (“First Trust”) is the AIFM of the Fund (“AIFM” means an alternative investment fund manager for the purposes of the AIFM Directive). First Trust is a non-EU AIFM.

The Trust has entered into agreements with various service providers including First Trust (as the Investment Advisor), the Custodian, Distributor, Transfer Agent, Administrator, index providers and the exchanges where the Fund is listed in respect of the Fund. Further details regarding the duties and roles of such service providers can be found in the Prospectus and the SAI for the Fund.

In addition to the parties listed above, the Trust has appointed (i) Chapman and Cutler LLP as its legal counsel which advises it on US legal matters; (ii) Deloitte & Touche LLP as the Fund’s auditors who undertake to audit the Fund’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB) (United States); and (iii) CT Corporation System as the Fund’s registered agent.

First Trust is not required to ensure that the Fund appoints, and the Fund has not appointed, a depositary for purposes of the AIFM Directive (a depositary in the context of the AIFM Directive, has a specific role and function. The appointment of such depositary is not required for non-EU AIFs with non-EU AIFMs). As such investors in the Fund has no rights as against any person in respect of the duties or liabilities of a depositary under the AIFM Directive.

Investors’ Contractual Rights. In respect of each of the service providers to the Fund, investors who purchase shares in the Fund in the secondary market have no direct rights of action against the service providers, as a matter of contract law or under the establishment documents of the Trust. The proper plaintiff in an action in respect of which a wrongdoing is alleged to have been committed against the Fund or the Trust by a service provider is, prima facie, the Trust itself. An investor may bring a derivative or similar action or proceeding (“Derivative Action”) against the Trust or the Fund to recover a judgment in its favor in accordance with the provisions of the Declaration. Accordingly, investors would have no direct contractual right against the relevant service provider for breach of the agreement governing its appointment by the Trust. The foregoing disclosure

is without prejudice to such other rights of action (for example, under the securities laws, tort law or in respect of breach of fiduciary duty) which might in certain situations be separately available to investors.

Investment in the Fund. Investors will buy shares in the Fund in secondary market transactions through brokers and will not subscribe for shares from the Trust directly. As such, there is no direct contractual relationship between the Fund and the investor in connection with the purchase or sale of shares. While the Fund is established under Massachusetts law and Massachusetts law does facilitate the enforcement of judgments obtained in foreign jurisdictions, investors who buy shares on the secondary market will have no direct contractual right of action against the Fund. Investors should refer to “How to Buy and Sell Shares” in the main body of the Prospectus for more detail. The foregoing disclosure is without prejudice to such other rights of action (for example, under the securities laws, tort law or in respect of breach of fiduciary duty) which might in certain situations be separately available to investors.

Redemption from the Fund. Non-US investors will sell shares in secondary market transactions through brokers and will not redeem shares from the Fund directly. Shares can be sold throughout the trading day like other publically traded shares. Investors should refer to “How to Buy and Sell Shares” in the main body of the Prospectus for more detail.

Liquidity Risk Management. Investors should note that while First Trust is not required to implement liquidity management arrangements in accordance with the AIFM Directive in respect of the Fund, the Fund is subject to the liquidity limitations established by the SEC. The Trustees have delegated to First Trust the day-to- day determination of illiquidity of equity and fixed income securities as described under “Illiquid Securities” in the SAI.

Treatment of Investors. The Trust and the AIFM do not offer any investors preferential treatment or the right to obtain preferential treatment. Whilst the Trust does not take specific steps to ensure the fair treatment of investors, under the 1940 Act the Trustees are required to monitor how the Fund operates and oversee matters where the interests of the Fund and its shareholders may differ from those of its investment adviser.

First Trust is registered as an investment adviser with the SEC, and is subject to regulation and oversight designed to protect shareholders. Under the Investment Advisers Act of 1940, First Trust is a fiduciary to its clients, the Fund, and is therefore required to act in the best interests of clients and to place the interests of clients before its own.

Information Regarding the use of Leverage and Collateral. The AIFM Directive requires disclosure of certain information relating to leverage, collateral and asset re-use arrangements. The Fund may obtain leverage through the use of derivatives and other non-fully funded investments such as reverse repurchase agreements, firm commitment agreements, standby commitment agreements if, and to the extent that, such transactions are (i) disclosed in the Fund’s Prospectus and SAI and (ii) deemed appropriate investments by First Trust. These leveraged trading practices generally have not been prohibited by the SEC, though the SEC has published guidance on the manner in which the Fund may cover their leveraged trading practices to limit leverage and avoid the need to address the leverage concerns in Section 18 of the 1940 Act, which severely restricts how the Fund may use leverage. All arrangements entered into by First Trust on behalf of the Fund which result in leverage follow the parameter of the guidance published by the SEC.

As a non-EU AIFM, First Trust is not obliged to set a maximum permitted level of leverage which it may employ in its management of the Fund. The total amount of leverage employed by the Fund is provided at www.ftglobalportfolios.com.

Investors should refer to the “Investment Objectives and Policies” and “Investment Strategies” section of the SAI for more details on the use and risk of leverage by the Fund.

Shareholder Voting Rights. The Declaration requires a shareholder vote only on those matters where the 1940 Act requires a vote of shareholders and otherwise permits the Trustees to take actions without seeking the consent of shareholders. The Fund’s fundamental policies, as described in the “Investment Objectives and Policies” section of the SAI, may not be changed without approval of the holders of a majority of the outstanding voting securities (as such term is defined in the 1940 Act) of the Fund. The 1940 Act defines a majority vote as the vote of the lesser of (i) 67% or more of the voting securities represented at a meeting at which more than 50% of the outstanding securities are represented; or (ii) more than 50% of the outstanding voting securities. Please refer to the SAI for further information.

Net Asset Value. The latest NAV of the Fund, and the latest NAV per share of each class of share of the Fund, is available online at: www.ftglobalportfolios.com and online stock quote services. Generally investors will buy and sell shares of the Fund in secondary market transactions through brokers. Shares of the Fund will therefore be available at the relevant market price rather than NAV.

The historical performance of the Fund since inception is available online at: www.ftglobalportfolios.com.

Accounts. Under the AIFM Directive, First Trust is required to make available the annual report of the Fund that it markets in the EEA. This must be prepared by no later than 6 months following the end of the financial year and contain certain specific content requirements set out in the AIFM Directive. Once the annual report has been produced, it will be made available to investors in the manner as set out in the Prospectus.

Professional Liability Requirements/Delegation by the AIFM/Valuation. As a non-EU AIFM, First Trust is not subject to certain EU requirements relating to (i) the cover of professional liability risk by holding either additional own funds or appropriate professional liability insurance; (ii) permitted delegation and the management and disclosure of conflicts of interest relating to any such delegation; and (iii) valuation as set out in Article 19 of the AIFM Directive. As such, no disclosures for the purposes of the AIFM Directive have been made. Notwithstanding this, First Trust and the Fund continue to comply with their requirements under US law.

Periodic Disclosure Obligations. The following information will be disclosed to Fund shareholders on a periodic basis by way of a posting being made on www.ftglobalportfolios.com:

•

the percentage of the Fund’s assets, if any, that are subject to special arrangements arising from their illiquid nature (including, but not limited to, deferrals of redemptions and suspensions);

•

the current risk profile of the Fund and the risk management systems employed by the AIFM to manage those risks; and

•

the total amount of leverage employed by the Fund, if any.

Whenever any new arrangements for managing the liquidity of the Fund are introduced including, but not limited to, any material changes to the liquidity management systems and procedures employed by First Trust, a disclosure to this effect will be uploaded on the Fund’s website. The Fund will ensure that a notice is uploaded on an expedited basis whenever deferrals or other similar special arrangements are activated or where redemptions of shares are suspended.

A notice will be posted without undue delay whenever there is a change to a maximum level of leverage which may be employed on behalf of the Fund; and any changes are made to the right of re-use of collateral or any changes to any guarantee granted under any leveraging arrangement.

Proxy Voting Policies and Procedures

The Trust has adopted a proxy voting policy that seeks to ensure that proxies for securities held by the Fund are voted consistently with the best interests of the Fund.

The Board has delegated to First Trust the proxy voting responsibilities for the Fund and has directed First Trust to vote proxies consistent with the Fund’s best interests. First Trust has engaged the services of Institutional Shareholder Services, Inc. (“ISS”), to make recommendations to First Trust on the voting of proxies relating to securities held by the Fund. If First Trust manages the assets of a company or its pension plan and any of First Trust’s clients hold any securities of that company, First Trust will vote proxies relating to such company’s securities in accordance with the ISS recommendations to avoid any conflict of interest.

Information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30, is available upon request and without charge on the Fund’s website at www.ftportfolios.com, by calling (800) 621-1675 or by accessing the SEC’s website at www.sec.gov.

and is filed with the SEC on Form N-CSR. A semi-annual or annual report for the Fund will become available to investors within 60 days after the period to which it relates. The Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.

Policy Regarding Disclosure of Portfolio Holdings. The Trust has adopted a policy regarding the disclosure of information about the Fund’s portfolio holdings. The Board of Trustees must approve all material amendments to this policy. The Fund’s portfolio holdings are publicly disseminated each day the Fund is open for business through financial reporting and news services, including publicly accessible Internet websites. In addition, a basket composition file, which includes the security names and share quantities to deliver in exchange for Fund shares, together with estimates and actual cash components, is publicly disseminated each day the NYSE is open for trading via the National Securities Clearing Corporation (“NSCC”). Pursuant to Rule 6c-11 under the 1940 Act, information regarding the Fund’s current portfolio holdings will be available on a daily basis at https://www.ftportfolios.com/Retail/etf/home.aspx. The Trust, First Trust, FTP and BNYM will not disseminate non-public information concerning the Trust.

Codes of Ethics. In order to mitigate the possibility that the Fund will be adversely affected by personal trading, the Trust, First Trust and the Distributor have adopted Codes of Ethics under Rule 17j-1 of the 1940 Act. These Codes of Ethics contain policies restricting securities trading in personal accounts of the officers, Trustees and others who normally come into possession of information on portfolio transactions. Personnel subject to the Codes of Ethics may invest in securities that may be purchased or held by the Fund; however, the Codes of Ethics require that each transaction in such securities be reviewed by the Chief Compliance Officer or his or her designee. These Codes of Ethics are on public file with, and are available from, the SEC.

Creation and Redemption of Creation Units

General. ETFs, such as the Fund, generally issue and redeem their shares in primary market transactions through a creation and redemption mechanism and do not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with an ETF or one of the ETF’s service providers to purchase and redeem ETF shares directly with the ETF in large blocks of shares known as “Creation Units.” Prior to start of trading on every business day, an ETF publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the ETF’s shares. An Authorized Participant that wishes to effectuate a creation of an ETF’s shares deposits with the ETF the “basket” of securities, cash or other assets identified by the ETF that day, and then receives the Creation Unit of the ETF’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the ETF’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the authorized participant redeems a Creation Unit of ETF shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in ETF shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of ETF shares at or close to the NAV per share of the ETF.

Authorized Participants. An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC that has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase or redemption of Creation Units (a “Participant Agreement”). Orders to purchase Creation Units must be delivered through an Authorized Participant that has executed a Participant Agreement and must comply with the applicable provisions of such Participant Agreement. Investors wishing to purchase or sell shares generally do so on an exchange. Institutional investors other than Authorized Participants are responsible for making arrangements for a redemption request to be made through an Authorized Participant.

Business Day. A “Business Day” is generally any day on which the New York Stock Exchange ( “NYSE” ), the Exchange and the Trust are open for business. As of the date of this SAI, the NYSE observes the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Business Day on which an order to purchase or redeem Creation Units is received in proper form is referred to as the “Transmittal Date.”

assets and other positions can legally and readily be acquired, transferred and held by the ETF and/or Authorized Participant(s), as applicable; (3) whether to utilize cash, either in lieu of securities or other instruments or as a cash balancing amount; and (4) in the case of an ETF that tracks an index, whether the securities, assets and other positions aid index tracking.

The Fund may utilize a pro rata basket or a custom basket in reliance on Rule 6c-11. A “pro rata basket” is a basket that is a pro rata representation of the ETF’s portfolio holdings, except for minor deviations when it is not operationally feasible to include a particular instrument within the basket, except to the extent that the Fund utilized different baskets in transactions on the same Business Day.

Rule 6c-11 defines “custom baskets” to include two categories of baskets. First, a basket containing a non-representative selection of the ETF’s portfolio holdings would constitute a custom basket. These types of custom baskets include, but are not limited to, baskets that do not reflect: (i) a pro rata representation of the Fund’s portfolio holdings; (ii) a representative sampling of an ETF’s portfolio holdings; or (iii) changes due to a rebalancing or reconstitution of an ETF’s securities market index, if applicable. Second, if different baskets are used in transactions on the same Business Day, each basket after the initial basket would constitute a custom basket. For example, if an ETF exchanges a basket with either the same or another Authorized Participant that reflects a representative sampling that differs from the initial basket, that basket (and any such subsequent baskets) would be a custom basket. Similarly, if an ETF substitutes cash in lieu of a portion of basket assets for a single Authorized Participant, that basket would be a custom basket. The Advisor’s Rule 6c-11 Committee defines any deviation from a pro rata basket to be a “custom basket.” Rebalancing and reconstitution baskets do not constitute custom baskets. All cash baskets that are the initial basket on a Business Day also do not constitute custom baskets.

Under a variety of circumstances, an ETF and its shareholders may benefit from the flexibility afforded by custom baskets. In general terms, the use of custom baskets may reduce costs, increase efficiency and improve trading. Because utilizing custom baskets provides a way for an ETF to add, remove and re-weight portfolio securities without transacting in the market, it may help the ETF to avoid transaction costs and adverse tax consequences. Rule 6c-11 provides an ETF with flexibility to use “custom baskets” if the ETF has adopted written policies and procedures that: (1) set forth detailed parameters for the construction and acceptance of custom baskets that are in the best interests of the ETF and its shareholders, including the process for any revisions to, or deviations from, those parameters; and (2) specify the titles or roles of employees of the ETF’s investment advisor who are required to review each custom basket for compliance with those parameters.

The use of baskets that do not correspond pro rata to an ETF’s portfolio holdings has historically created concern that an Authorized Participant could take advantage of its relationship with an ETF and pressure the ETF to construct a basket that favors an Authorized Participant to the detriment of the ETF’s shareholders. For example, because ETFs rely on Authorized Participants to maintain the secondary market by promoting an effective arbitrage mechanism, an Authorized Participant holding less liquid or less desirable securities potentially could pressure an ETF into accepting those securities in its basket in exchange for liquid ETF shares (i.e., dumping). An Authorized Participant also could pressure the ETF into including in its basket certain desirable securities in exchange for ETF shares tendered for redemption (i.e., cherry-picking). In either case, the ETF’s other investors would be disadvantaged and would be left holding shares of an ETF with a less liquid or less desirable portfolio of securities. The Advisor has adopted policies and procedures designed to mitigate these concerns but there is ultimately no guarantee that such policies and procedures will be effective.

Basket Dissemination. Basket files are published for consumption through the NSCC, a subsidiary of Depository Trust & Clearing Corporation, and can be utilized for pricing, creations, redemptions, rebalancing and custom scenarios. In most instances, pro rata baskets are calculated and supplied by the ETF’s custodial bank based on ETF holdings, whereas non-pro rata, custom and forward-looking pro rata baskets are calculated by the Fund’s investment advisor and disseminated by the ETF’s custodial bank through the NSCC process.

Placement of Creation or Redemption Orders. All orders to purchase or redeem Creation Units are to be governed according to the applicable Participant Agreement that each Authorized Participant has executed. In general, all orders to purchase or redeem Creation Units must be received by the transfer agent in the proper form required by the Participant Agreement no later than the closing time of the regular trading session of the NYSE (ordinarily 4:00 p.m. Eastern Standard Time) on each day the NYSE is open for business (the “Closing Time”) in order for the purchase or redemption of Creation Units to be effected based on the NAV of shares of the Fund as next determined on such date after receipt of the order in proper form. However, at its discretion, the Fund may require an Authorized Participant to submit orders to purchase or redeem Creation Units be placed earlier in the day (such as instances where an applicable market for a security comprising a creation or redemption basket closes earlier than usual).

Delivery of Redemption Proceeds. Deliveries of securities to Authorized Participants in connection with redemption orders are generally expected to be made within two Business Days. Due to the schedule of holidays in certain countries, however, the delivery of in-kind redemption proceeds for the Fund may take longer than two Business Days after the day on which the redemption request is received in proper form. Section 22(e) of the 1940 Act generally prohibits a registered open-end management investment company from postponing the date of satisfaction of redemption requests for more than seven days after the tender of a security for redemption. This prohibition can cause operational difficulties for ETFs that hold foreign investments and exchange in-kind baskets for Creation Units. For example, local market delivery cycles for transferring foreign investments to redeeming investors, together with local market holiday schedules, can sometimes require a delivery process in excess of seven days. However, Rule 6c-11 grants relief from Section 22(e) to permit an ETF to delay satisfaction of a redemption request for more than seven days if a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming Authorized Participants, or the combination thereof prevents timely delivery of the foreign investment included in the ETF’s basket. Under this exemption, an ETF must deliver foreign investments as soon as practicable, but in no event later than 15 days after the tender to the ETF. The exemption therefore will permit a delay only to the extent that additional time for settlement is actually required, when a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming authorized participants prevents timely delivery of the foreign investment included in the ETF’s basket. If a foreign investment settles in less than 15 days, Rule 6c-11 requires an ETF to deliver it pursuant to the standard settlement time of the local market where the investment trades. Rule 6c-11 defines “foreign investment” as any security, asset or other position of the ETF issued by a foreign issuer (as defined by Rule 3b-4 under the 1934 Act), and that is traded on a trading market outside of the United States. This definition is not limited to “foreign securities,” but also includes other investments that may not be considered securities. Although these other investments may not be securities, they may present the same challenges for timely settlement as foreign securities if they are transferred in kind.

Creation Transaction Fees. The Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various facts-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.

Redemption Transaction Fees. The Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various facts-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.

Suspension of Creations. The SEC has stated its position that an ETF generally may suspend the issuance of Creation Units only for a limited time and only due to extraordinary circumstances, such as when the markets on which the ETF’s portfolio holdings are traded are closed for a limited period of time. The SEC has also stated that an ETF could not set transaction fees so high as to effectively suspend the issuance of Creation Units. Circumstances in which the Fund may suspend creations include, but are not limited to: (i) the order is not in proper form; (ii) the purchaser or group of related purchasers, upon obtaining the Creation Units of Fund shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the required consideration is not delivered; (iv) the acceptance of the basket would have certain adverse tax consequences; (v) the acceptance of the basket would, in the opinion of the Fund, be unlawful; (vi) the acceptance of the basket would otherwise, in the discretion of the Fund, First Trust and/or any sub-advisor, have an adverse effect on the Fund or the rights of the Fund’s Beneficial Owners; or (vii) there exist circumstances outside the control of the Fund that make it impossible to process purchases of Creation Units for all practical purposes. Examples of such circumstances include: acts of God or public service or utility problems such as fires, floods, extreme weather conditions and power outages resulting in telephone, telecopy and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the Fund, First Trust, the Distributor, DTC, NSCC, the transfer agent, the custodian, any sub-custodian or any other participant in the purchase process; and similar extraordinary events. The Fund reserves the absolute right to reject a creation order transmitted to it. The Transfer Agent shall notify a prospective creator of a Creation Unit and/or the Authorized Participant acting on behalf

of such prospective creator of the rejection of the order of such person. The Trust, the Fund, the Transfer Agent, the custodian, any sub-custodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of baskets, nor shall any of them incur any liability for the failure to give any such notification.

Suspension of Redemptions. An ETF may suspend the redemption of Creation Units only in accordance with Section 22(e) of the 1940 Act. Section 22(e) stipulates that no registered investment company shall suspend the right of redemption, or postpone the date of payment or satisfaction upon redemption of any redeemable security in accordance with its terms for more than seven days after the tender of such security to the company or its agent designated for that purpose for redemption, except (1) for any period (A) during which the NYSE is closed other than customary week-end and holiday closings or (B) during which trading on the NYSE is restricted; (2) for any period during which an emergency exists as a result of which (A) disposal by the investment company of securities owned by it is not reasonably practicable or (B) it is not reasonably practicable for such company fairly to determine the value of its net assets; or (3) for such other periods as the SEC may by order permit for the protection of security holders of the investment company.

Exceptions to Use of Creation Units. Under Rule 6c-11 of the 1940 Act, ETFs are permitted to sell or redeem individual shares on the day of consummation of a reorganization, merger, conversion, or liquidation. In these limited circumstances, an ETF may need to issue or redeem individual shares and may need to transact without utilizing Authorized Participants.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of the SAI. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or foreign tax consequences.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, our counsel was not asked to review, and has not reached a conclusion with respect to the federal income tax treatment of the assets to be deposited in the Fund. The following disclosure may not be sufficient for prospective investors to use for the purpose of avoiding penalties under federal tax law.

As with any investment, prospective investors should seek advice based on their individual circumstances from their own tax advisor.

The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”).

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, taxable interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

and net capital gain. If the Fund retains any net capital gain or investment company taxable income, it will generally be subject to federal income tax at regular corporate rates on the amount retained. In addition, amounts not distributed on a timely basis in accordance with a calendar year distribution requirement are subject to a nondeductible 4% excise tax unless, generally, the Fund distributes during each calendar year an amount equal to the sum of (1) at least 98% of its ordinary income (not taking into account any capital gains or losses) for the calendar year, (2) at least 98.2% of its capital gains in excess of its capital losses (adjusted for certain ordinary losses) for the one-year period ending October 31 of the calendar year, and (3) any ordinary income and capital gains for previous years that were not distributed during those years. In order to prevent application of the excise tax, the Fund intends to make its distributions in accordance with the calendar year distribution requirement. A distribution will be treated as paid on December 31 of the current calendar year if it is declared by the Fund in October, November or December with a record date in such a month and paid by the Fund during January of the following calendar year. Such distributions will be taxable to shareholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received.

Subject to certain reasonable cause and de minimis exceptions, if the Fund fails to qualify as a regulated investment company or fails to satisfy the 90% distribution requirement in any taxable year, the Fund would be taxed as an ordinary corporation on its taxable income (even if such income were distributed to its shareholders) and all distributions out of earnings and profits would be taxed to shareholders as ordinary income.

Distributions

Dividends that qualify as “exempt-interest dividends” generally are excluded from gross income for federal income tax purposes. Some or all of the exempt-interest dividends, however, may be taken into account in determining a shareholder’s alternative minimum tax and may have other tax consequences (e.g., they may affect the amount of a shareholder’s social security benefits that are taxed). Other dividends paid out of the Fund’s investment company taxable income are generally taxable to a shareholder as ordinary income to the extent of the Fund’s earnings and profits, whether paid in cash or reinvested in additional shares.

Income from the Fund may also be subject to a 3.8% “Medicare tax.” This tax generally applies to net investment income if the taxpayer’s adjusted gross income exceeds certain threshold amounts, which are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single individuals. Interest that is excluded from gross income and exempt-interest dividends from the Fund are generally not included in net investment income for purposes of this tax.

Distributions of net capital gain (the excess of net long-term capital gain over net short-term capital loss), if any, properly reported as capital gain dividends are taxable to a shareholder as long-term capital gains, regardless of how long the shareholder has held Fund shares. An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements. Shareholders receiving distributions in the form of additional shares, rather than cash, generally will have a tax basis in each such share equal to the value of a share of the Fund on the reinvestment date. A distribution of an amount in excess of the Fund’s current and accumulated earnings and profits will be treated by a shareholder as a return of capital which is applied against and reduces the shareholder’s basis in his or her shares. To the extent that the amount of any such distribution exceeds the shareholder’s basis in his or her shares, the excess will be treated by the shareholder as gain from a sale or exchange of the shares.

Shareholders will be notified annually as to the U.S. federal income tax status of distributions, and shareholders receiving distributions in the form of additional shares will receive a report as to the value of those shares.

Sale or Exchange of Fund Shares

Upon the sale or other disposition of shares of the Fund, which a shareholder holds as a capital asset, such shareholder may realize a capital gain or loss which will be long-term or short-term, depending upon the shareholder’s holding period for the shares. Generally, a shareholder’s gain or loss will be a long-term gain or loss if the shares have been held for more than one year. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Any loss realized on a sale or exchange will be disallowed to the extent that shares disposed of are replaced (including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after disposition of shares or to the extent that the shareholder, during such period, acquires or enters into an option or contract to acquire, substantially identical stock or securities. In such a case, the basis of the shares acquired will be adjusted to reflect the disallowed loss. Any loss realized by a shareholder on a disposition of Fund shares held by the shareholder for six months or less will be disallowed to the extent of the exempt-interest dividends the shareholder received, except in the case of a regular dividend paid by the Fund if the Fund declares exempt-interest dividends on a daily basis in an amount equal to at least 90 percent of its net tax-exempt interest and distributes such dividends on a monthly or more frequent basis. To the extent, if any, it is not disallowed, it will be recharacterized as long-term capital loss to the extent of any capital gain dividend received.

Taxes on Purchase and Redemption of Creation Units

If a shareholder exchanges securities for Creation Units, the shareholder will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the shareholder’s aggregate basis in the securities surrendered and the Cash Component paid. If a shareholder exchanges Creation Units for securities, then the shareholder will generally recognize a gain or loss equal to the difference between the shareholder’s basis in the Creation Units and the aggregate market value of the securities received and the Cash Redemption Amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Nature of Fund Investments

Certain of the Fund’s investment practices are subject to special and complex federal income tax provisions that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions; (ii) convert lower taxed long-term capital gain into higher taxed short-term capital gain or ordinary income; (iii) convert an ordinary loss or a deduction into a capital loss (the deductibility of which is more limited); (iv) cause the Fund to recognize income or gain without a corresponding receipt of cash; (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur; and (vi) adversely alter the characterization of certain complex financial transactions.

Futures Contracts and Options

The Fund’s transactions in futures contracts and options will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital, or short-term or long-term), may accelerate recognition of income to the Fund and may defer Fund losses. These rules could, therefore, affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out), and (b) may cause the Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% distribution requirement for qualifying to be taxed as a regulated investment company and the distribution requirements for avoiding excise taxes.

Investments in Certain Foreign Corporations

If the Fund holds an equity interest in any “passive foreign investment companies” (“PFICs”), which are generally certain foreign corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax (described above). Dividends paid by PFICs are not treated as qualified dividend income.

Backup Withholding

The Fund may be required to withhold U.S. federal income tax from all taxable distributions and sale proceeds payable to shareholders who fail to provide the Fund with their correct taxpayer identification number or fail to make required certifications, or who have been notified by the Internal Revenue Service that they are subject to backup withholding. Corporate shareholders and certain other shareholders specified in the Code generally are exempt from such backup withholding. This withholding is not an additional tax. Any amounts withheld may be credited against the shareholder’s U.S. federal income tax liability.

Non-U.S. Shareholders

U.S. taxation of a shareholder who, as to the United States, is a nonresident alien individual, a foreign trust or estate, a foreign corporation or foreign partnership (“non-U.S. shareholder”) depends on whether the income of the Fund is “effectively connected” with a U.S. trade or business carried on by the shareholder.

In addition to the rules described in this section concerning the potential imposition of withholding on distributions to non-U.S. persons, distributions to non-U.S. persons that are “financial institutions” may be subject to a withholding tax of 30% unless an agreement is in place between the financial institution and the U.S. Treasury to collect and disclose information about accounts, equity investments or debt interests in the financial institution held by one or more U.S. persons or the institution is resident in a jurisdiction that has entered into such an agreement with the U.S. Treasury. For these purposes, a “financial institution” means any entity that (i) accepts deposits in the ordinary course of a banking or similar business; (ii) holds financial assets for the account of others as a substantial portion of its business; or (iii) is engaged (or holds itself out as being engaged) primarily in the business of investing, reinvesting or trading in securities, partnership interests, commodities or any interest (including a futures contract or option) in such securities, partnership interests or commodities. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

Distributions to non-financial non-U.S. entities (other than publicly traded foreign entities, entities owned by residents of U.S. possessions, foreign governments, international organizations, or foreign central banks) will also be subject to a withholding tax of 30% if the entity does not certify that the entity does not have any substantial U.S. owners or provide the name, address and TIN of each substantial U.S. owner. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

Income Not Effectively Connected. If the income from the Fund is not “effectively connected” with a U.S. trade or business carried on by the non-U.S. shareholder, distributions of investment company taxable income, generally not including exempt-interest dividends, will generally be subject to a U.S. tax of 30% (or lower treaty rate), which tax is generally withheld from such distributions.

Distributions of capital gain dividends and any amounts retained by the Fund which are properly reported by the Fund as undistributed capital gains will not be subject to U.S. tax at the rate of 30% (or lower treaty rate) unless the non-U.S. shareholder is a nonresident alien individual and is physically present in the United States for more than 182 days during the taxable year and meets certain other requirements. However, this 30% tax on capital gains of nonresident alien individuals who are physically present in the United States for more than the 182 day period only applies in exceptional cases because any individual present in the United States for more than 182 days during the taxable year is generally treated as a resident for U.S. income tax purposes; in that case, he or she would be subject to U.S. income tax on his or her worldwide income at the graduated rates applicable to U.S. citizens, rather than the 30% U.S. tax. In the case of a non-U.S. shareholder who is a nonresident alien individual, the Fund may be required to withhold U.S. income tax from distributions of net capital gain unless the non-U.S. shareholder certifies his or her non-U.S. status under penalties of perjury or otherwise establishes an exemption. If a non-U.S. shareholder is a nonresident alien individual, any gain such shareholder realizes upon the sale or exchange of such shareholder’s shares of the Fund in the United States will ordinarily be exempt from U.S. tax unless the gain is U.S. source income and such shareholder is physically present in the United States for more than 182 days during the taxable year and meets certain other requirements. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. shareholders, provided that the Fund makes certain elections and certain other conditions are met. In addition, capital gain distributions attributable to gains from U.S. real property interests (including certain U.S. real property holding corporations) will generally be subject to United States withholding tax and will give rise to an obligation on the part of the non-U.S. shareholder to file a United States tax return.

Income Effectively Connected. If the income from the Fund is “effectively connected” with a U.S. trade or business carried on by a non-U.S. shareholder, then distributions of investment company taxable income, generally not including exempt-interest dividends, and capital gain dividends, any amounts retained by the Fund which are properly reported by the Fund as undistributed capital gains and any gains realized upon the sale or exchange of shares of the Fund will be subject to U.S. income tax at the graduated rates applicable to U.S. citizens, residents and domestic corporations. Non-U.S. corporate shareholders may also be subject to the branch profits tax imposed by the Code. The tax consequences to a non-U.S. shareholder entitled to claim the benefits of an applicable tax treaty may differ from those described herein. Non-U.S. shareholders are advised to consult their own tax advisors with respect to the particular tax consequences to them of an investment in the Fund.

Capital Loss Carry-forward

Under the Regulated Investment Company Modernization Act of 2010, net capital losses of the Fund incurred in taxable years beginning after December 22, 2010 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. To the extent that these loss carry-forwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to Fund shareholders. As of October 31, 2020, the Fund had net capital losses for federal income tax purposes shown in the table below. The Fund is subject to certain limitations, under U.S. tax rules, on the use of capital loss carry-forwards and net unrealized built-in losses. These limitations generally apply when there has been a 50% change in ownership.

Determination of Net Asset Value

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “Net Asset Value.”

The per share net asset value of the Fund is determined by dividing the total value of the securities and other assets, less liabilities, by the total number of shares outstanding. Under normal circumstances, daily calculation of the net asset value will utilize the last closing sale price of each security held by the Fund at the close of the market on which such security is principally listed. In determining net asset value, portfolio securities for the Fund for which accurate market quotations are readily available will be valued by the Fund accounting agent as follows:

(1)

Common stocks and other equity securities listed on any national or foreign exchange other than Nasdaq and the London Stock Exchange Alternative Investment Market (“AIM”) will be valued at the last sale price on the exchange on which they are principally traded, or the official closing price for Nasdaq and AIM securities. Portfolio securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the Business Day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

(2)

Shares of open-end funds are valued at fair value which is based on NAV per share.

(3)

Securities traded in the OTC market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

(4)

Exchange-traded options and futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, they will be fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. OTC options and futures contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

(5)

Forward foreign currency contracts are fair valued at the current day’s interpolated foreign exchange rate, as calculated using the current day’s spot rate, and the 30-, 60-, 90- and 180-day forward rates provided by an independent pricing service or by certain independent dealers in such contracts.

In addition, the following types of securities will be fair valued by the Fund accounting agent as follows:

(1)

Fixed-income securities, convertible securities, interest rate swaps, credit default swaps, total return swaps, currency swaps, currency-linked notes, credit-linked notes and other similar instruments will be fair valued using a pricing service.

(2)

Fixed-income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:

(i)

the credit conditions in the relevant market and changes thereto;

(ii)

the liquidity conditions in the relevant market and changes thereto;

(iii)

the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);

(iv)

issuer-specific conditions (such as significant credit deterioration); and

(v)

any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.

(3)

Repurchase agreements will be valued as follows. Overnight repurchase agreements will be fair valued at amortized cost when it represents the best estimate of fair value. Term repurchase agreements (i.e., those whose maturity exceeds seven days) will be fair valued by the Advisor’s Pricing Committee at the average of the bid quotations obtained daily from at least two recognized dealers.

If the Advisor’s Pricing Committee has reason to question the accuracy or reliability of a price supplied or the use of the amortized cost methodology, the Advisor’s Pricing Committee shall determine if “it needs to fair value” such portfolio security pursuant to established valuation procedures. From time to time, the Advisor’s Pricing Committee will request that the Fund accounting agent submit price challenges to a pricing service, usually in response to any updated broker prices received.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities that may not be publicly sold without registration under the 1933 Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of Fund net asset value (as may be the case in foreign markets on which the security is primarily traded) or is likely to make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. Fair value prices represent any prices not considered market value prices and are either obtained from a pricing service or are determined by the Advisor’s Pricing Committee. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from pricing services. If no market price or official close price is available from either a pricing service or no quotations are available from one or more brokers or if the Advisor’s Pricing Committee has reason to question the reliability or accuracy of a price supplied or the use of amortized cost, the value of any portfolio security held by the Fund for which reliable market prices/quotations are not readily available will be determined by the Advisor’s Pricing Committee in a manner that most appropriately reflects fair market value of the security on the valuation date, based on a consideration of all available information. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchange.

Because foreign markets may be open on different days than the days during which a shareholder may buy or sell shares of the Fund, the value of the Fund's investments may change on the days when shareholders are not able to buy or

sell shares of the Fund. For foreign securities, if an extraordinary market event occurs between the time the last “current” market quotation is available for a security in the Fund’s portfolio and the time the Fund’s net asset value is determined and calls into doubt whether that earlier market quotation represents fair value at the time the Fund’s net asset value is determined, the Fund accounting agent will immediately notify the Advisor’s Pricing Committee and the Advisor’s Pricing Committee shall determine the fair valuation. For foreign securities, the Advisor’s Pricing Committee may seek to determine the “fair value” of such securities by retaining a pricing service to determine the value of the securities.

Foreign securities, currencies and other assets denominated in foreign currencies are translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar as provided by a pricing service. All assets denominated in foreign currencies will be converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Dividends and Distributions

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “Dividends, Distributions and Taxes.”

General Policies. Dividends from net investment income of the Fund, if any, are declared and paid monthly. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve the status of the Fund as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income.

Dividends and other distributions of Fund shares are distributed, as described below, on a pro rata basis to Beneficial Owners of such shares. Dividend payments are made through DTC Participants and Indirect Participants to Beneficial Owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by Beneficial Owners of the Fund for reinvestment of their dividend distributions. Beneficial Owners should contact their brokers in order to determine the availability and costs of the service and the details of participation therein. Brokers may require Beneficial Owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Exhibit B—Credit Rating Definitions

Standard & Poor’s

A Standard & Poor’s issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects Standard & Poor’s view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based, in varying degrees, on the following considerations:

Likelihood of payment: capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

Nature of and provisions of the obligation and the promise S&P imputes;

Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

The issue rating definitions are an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

AAA	An obligation rated “AAA” has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.
AA	An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.
A	An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.
BBB	An obligation rated “BBB” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

Obligations rated “BB,” “B,” “CCC,” “CC” and “C” are regarded as having significant speculative characteristics. “BB” indicates the least degree of speculation and “C” the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB	An obligation rated “BB” is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	An obligation rated “B” is more vulnerable to nonpayment than obligations rated “BB,” but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	An obligation rated “CCC” is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.
CC	An obligation rated “CC” is currently highly vulnerable to nonpayment. The “CC” rating is used when a default has not yet occurred but S&P expects default to be a virtual certainty regardless of the anticipated time to default.

B-1

An obligation rated “C” is currently highly vulnerable to nonpayment and the obligation is expected to have

lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.

An obligation rated “D” is in default or in breach of an imputed promise. For non-hybrid capital instruments,

the “D” rating category is used when payments on an obligation are not made on the date due unless S&P

believes that such payments will be made within five business days in the absence of a stated grace period or

within the earlier of the stated grace period or 30 calendar days. The “D” rating also will be used upon the

filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual

certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to

a distressed exchange offer.

Plus (+) or Minus (-): The ratings from “AA” to “CCC” may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

Moody’s Investors Service, Inc.

A brief description of the applicable Moody’s Investors Service, Inc. (“Moody’s”) rating symbols and their meanings (as published by Moody’s) follows.

Ratings assigned on Moody’s global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect the likelihood of a default on contractually promised payments.

LONG-TERM OBLIGATION RATINGS

Aaa	Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.
Aa	Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.
A	Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.
Baa	Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.
Ba	Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.
B	Obligations rated B are considered speculative and are subject to high credit risk.
Caa	Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.
Ca	Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.
C	Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Fitch Ratings

A brief description of the applicable Fitch Ratings (“Fitch”) ratings symbols and meanings (as published by Fitch) follows:

Fitch’s credit ratings provide an opinion on the relative ability of an entity to meet financial commitments, such as interest, preferred dividends, repayment of principal, insurance claims or counterparty obligations. Credit ratings are used by investors as indications of the likelihood of receiving the money owed to them in accordance with the terms on which they invested. The agency’s credit ratings cover the global spectrum of corporate, sovereign (including supranational and sub-national), financial, bank, insurance, municipal and other public finance entities and the securities or other obligations they issue, as well as structured finance securities backed by receivables or other financial assets.

The terms “investment grade” and “speculative grade” have established themselves over time as shorthand to describe the categories ‘AAA’ to ‘BBB’ (investment grade) and ‘BB’ to ‘D’ (speculative grade). The terms “investment grade” and “speculative grade” are market conventions, and do not imply any recommendation or endorsement of a specific security for investment

B-2

purposes. “Investment grade” categories indicate relatively low to moderate credit risk, while ratings in the “speculative” categories either signal a higher level of credit risk or that a default has already occurred.

A designation of “Not Rated” or “NR” is used to denote securities not rated by Fitch where Fitch has rated some, but not all, securities comprising an issuance capital structure.

Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss.

Fitch’s credit ratings do not directly address any risk other than credit risk. In particular, ratings do not deal with the risk of a market value loss on a rated security due to changes in interest rates, liquidity and other market considerations. However, in terms of payment obligation on the rated liability, market risk may be considered to the extent that it influences the ability of an issuer to pay upon a commitment. Ratings nonetheless do not reflect market risk to the extent that they influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of index-linked bonds).

In the default components of ratings assigned to individual obligations or instruments, the agency typically rates to the likelihood of non-payment or default in accordance with the terms of that instrument’s documentation. In limited cases, Fitch may include additional considerations (i.e. rate to a higher or lower standard than that implied in the obligation’s documentation). In such cases, the agency will make clear the assumptions underlying the agency’s opinion in the accompanying rating commentary.

INTERNATIONAL LONG-TERM RATINGS

Issuer Credit Rating Scales

Investment Grade

AAA	Highest credit quality. ‘AAA’ ratings denote the lowest expectation of default risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
AA	Very high credit quality. ‘AA’ ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.
A	High credit quality. ‘A’ ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
BBB	Good credit quality. ‘BBB’ ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.
BB	Speculative. ‘BB’ ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists which supports the servicing of financial commitments.
B	Highly speculative. ‘B’ ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.
CCC	Substantial credit risk. Default is a real possibility.
CC	Very high levels of credit risk. Default of some kind appears probable.
C	Exceptionally high levels of credit risk. Default is imminent or inevitable, or the issuer is in standstill. Conditions that are indicative of a ‘C’ category rating for an issuer include: •the issuer has entered into a grace or cure period following non-payment of a material financial obligation; •the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; or •Fitch otherwise believes a condition of ‘RD’ or ‘D’ to be imminent or inevitable, including through the formal announcement of a distressed debt exchange.

➤

The board's rationale for adopting the bylaw/charter amendment without shareholder ratification;

➤

Disclosure by the company of any significant engagement with shareholders regarding the amendment;

➤

The level of impairment of shareholders' rights caused by the board's unilateral amendment to the bylaws/charter;

Unless the adverse amendment is reversed or submitted to a binding shareholder vote, in subsequent years vote case-by-case on director nominees. Generally, vote against (except new nominees1, who should be considered case-by-case) if the directors:

➤

Classified the board;

➤

Adopted supermajority vote requirements to amend the bylaws or charter; or

➤

Eliminated shareholders' ability to amend bylaws.

Problematic Capital Structure – Newly Public Companies: For newly public companies8, generally vote against or withhold from the entire board (except new nominees1, who should be considered case-by-case) if, prior to or in connection with the company's public offering, the company or its board implemented a multi-class capital structure in which the classes have unequal voting rights without subjecting the multi-class capital structure to a reasonable time-based sunset. In assessing the reasonableness of a time-based sunset provision, consideration will be given to the company’s lifespan, its post-IPO ownership structure and the board’s disclosed rationale for the sunset period selected. No sunset period of more than seven years from the date of the IPO will be considered to be reasonable.

Continue to vote against or withhold from incumbent directors in subsequent years, unless the problematic capital structure is reversed or removed.

Problematic Governance Structure – Newly Public Companies: For newly public companies8, generally vote against or withhold from directors individually, committee members, or the entire board (except new nominees1, who should be considered case-by-case) if, prior to or in connection with the company's public offering, the company or its board adopted the following bylaw or charter provisions that are considered to be materially adverse to shareholder rights:

➤

Supermajority vote requirements to amend the bylaws or charter;

Restrictions on Shareholders’ Rights

Restricting Binding Shareholder Proposals: Generally, vote against or withhold from the members of the governance committee if:

➤

The company’s governing documents impose undue restrictions on shareholders’ ability to amend the bylaws. Such restrictions include but are not limited to: outright prohibition on the submission of binding shareholder proposals or share ownership requirements, subject matter restrictions, or time holding requirements in excess of SEC Rule 14a-8. Vote against or withhold on an ongoing basis.

Submission of management proposals to approve or ratify requirements in excess of SEC Rule 14a-8 for the submission of binding bylaw amendments will generally be viewed as an insufficient restoration of shareholders' rights. Generally continue to vote against or withhold on an ongoing basis until shareholders are provided with an unfettered ability to amend the bylaws or a proposal providing for such unfettered right is submitted for shareholder approval.

Problematic Audit-Related Practices

Generally vote against or withhold from the members of the Audit Committee if:

➤

The non-audit fees paid to the auditor are excessive;

➤

The company receives an adverse opinion on the company’s financial statements from its auditor; or

➤

There is persuasive evidence that the Audit Committee entered into an inappropriate indemnification agreement with its auditor that limits the ability of the company, or its shareholders, to pursue legitimate legal recourse against the audit firm.

Vote case-by-case on members of the Audit Committee and potentially the full board if:

➤

Poor accounting practices are identified that rise to a level of serious concern, such as: fraud; misapplication of GAAP; and material weaknesses identified in Section 404 disclosures. Examine the severity, breadth, chronological sequence, and duration, as well as the company’s efforts at remediation or corrective actions, in determining whether withhold/against votes are warranted.

Problematic Compensation Practices

In the absence of an Advisory Vote on Executive Compensation (Say on Pay) ballot item or in egregious situations, vote against or withhold from the members of the Compensation Committee and potentially the full board if:

➤

There is an unmitigated misalignment between CEO pay and company performance (pay for performance);

➤

The company maintains significant problematic pay practices; or

➤

The board exhibits a significant level of poor communication and responsiveness to shareholders.

Generally, vote against or withhold from the Compensation Committee chair, other committee members, or potentially the full board if:

Shareholder Rights & Defenses

Advance Notice Requirements for Shareholder Proposals/Nominations

➤

General Recommendation: Vote case-by-case on advance notice proposals, giving support to those proposals which allow shareholders to submit proposals/nominations as close to the meeting date as reasonably possible and within the broadest window possible, recognizing the need to allow sufficient notice for company, regulatory, and shareholder review.

To be reasonable, the company’s deadline for shareholder notice of a proposal/nominations must be no earlier than 120 days prior to the anniversary of the previous year’s meeting and have a submittal window of no shorter than 30 days from the beginning of the notice period (also known as a 90-120 day window). The submittal window is the period under which shareholders must file their proposals/nominations prior to the deadline.

In general, support additional efforts by companies to ensure full disclosure in regard to a proponent’s economic and voting position in the company so long as the informational requirements are reasonable and aimed at providing shareholders with the necessary information to review such proposals.

Shareholder Litigation Rights

Federal Forum Selection Provisions

Federal forum selection provisions require that U.S. federal courts be the sole forum for shareholders to litigate claims arising under federal securities law.

➤

General Recommendation: Generally vote for federal forum selection provisions in the charter or bylaws that specify "the district courts of the United States" as the exclusive forum for federal securities law matters, in the absence of serious concerns about corporate governance or board responsiveness to shareholders.

Vote against provisions that restrict the forum to a particular federal district court; unilateral adoption (without a shareholder vote) of such a provision will generally be considered a one-time failure under the Unilateral Bylaw/Charter Amendments policy.

Exclusive Forum Provisions for State Law Matters

Exclusive forum provisions in the charter or bylaws restrict shareholders’ ability to bring derivative lawsuits against the company, for claims arising out of state corporate law, to the courts of a particular state (generally the state of incorporation).

➤

General Recommendation: Generally vote for charter or bylaw provisions that specify courts located within the state of Delaware as the exclusive forum for corporate law matters for Delaware corporations, in the absence of serious concerns about corporate governance or board responsiveness to shareholders.

For states other than Delaware, vote case-by-case on exclusive forum provisions, taking into consideration:

➤

The company's stated rationale for adopting such a provision;

➤

The Current Request:

➤

Disclosure in the proxy statement of the specific purposes of the proposed increase;

➤

Disclosure in the proxy statement of specific and severe risks to shareholders of not approving the request; and

➤

The dilutive impact of the request as determined relative to an allowable increase calculated by ISS (typically 100 percent of existing authorized shares) that reflects the company's need for shares and total shareholder returns.

ISS will apply the relevant allowable increase below to requests to increase common stock that are for general corporate purposes (or to the general corporate purposes portion of a request that also includes a specific need):

Most companies: 100 percent of existing authorized shares.

Companies with less than 50 percent of existing authorized shares either outstanding or reserved for issuance: 50 percent of existing authorized shares.

Companies with one- and three-year total shareholder returns (TSRs) in the bottom 10 percent of the U.S. market as of the end of the calendar quarter that is closest to their most recent fiscal year end: 50 percent of existing authorized shares.

Companies at which both conditions (B and C) above are both present: 25 percent of existing authorized shares.

If there is an acquisition, private placement, or similar transaction on the ballot (not including equity incentive plans) that ISS is recommending FOR, the allowable increase will be the greater of (i) twice the amount needed to support the transactions on the ballot, and (ii) the allowable increase as calculated above.

Mergers and Acquisitions

➤

General Recommendation: Vote case-by-case on mergers and acquisitions. Review and evaluate the merits and drawbacks of the proposed transaction, balancing various and sometimes countervailing factors including:

➤

Valuation - Is the value to be received by the target shareholders (or paid by the acquirer) reasonable? While the fairness opinion may provide an initial starting point for assessing valuation reasonableness, emphasis is placed on the offer premium, market reaction, and strategic rationale.

➤

Market reaction - How has the market responded to the proposed deal? A negative market reaction should cause closer scrutiny of a deal.

➤

Strategic rationale - Does the deal make sense strategically? From where is the value derived? Cost and revenue synergies should not be overly aggressive or optimistic, but reasonably achievable. Management should also have a favorable track record of successful integration of historical acquisitions.

➤

Negotiations and process - Were the terms of the transaction negotiated at arm's-length? Was the process fair and equitable? A fair process helps to ensure the best price for shareholders. Significant negotiation "wins" can also signify the deal makers' competency. The comprehensiveness of the sales process (e.g., full auction, partial auction, no auction) can also affect shareholder value.

➤

Conflicts of interest - Are insiders benefiting from the transaction disproportionately and inappropriately as compared to non-insider shareholders? As the result of potential conflicts, the directors and officers of the company may be more likely to vote to approve a merger than if they did not hold these interests. Consider whether these interests may have influenced these directors and officers to support or recommend the merger. The CIC figure presented in the "ISS Transaction Summary" section of this report is an aggregate figure that can in certain cases be a misleading indicator of the true value transfer from shareholders to insiders. Where such figure appears to be excessive, analyze the underlying assumptions to determine whether a potential conflict exists.

C-11ISSGOVERNANCE.COM

U.S. Concise Proxy Voting Guidelines

➤

Governance - Will the combined company have a better or worse governance profile than the current governance profiles of the respective parties to the transaction? If the governance profile is to change for the worse, the burden is on the company to prove that other issues (such as valuation) outweigh any deterioration in governance.

Compensation

Executive Pay Evaluation

Underlying all evaluations are five global principles that most investors expect corporations to adhere to in designing and administering executive and director compensation programs:

➤

Maintain appropriate pay-for-performance alignment, with emphasis on long-term shareholder value: This principle encompasses overall executive pay practices, which must be designed to attract, retain, and appropriately motivate the key employees who drive shareholder value creation over the long term. It will take into consideration, among other factors, the link between pay and performance; the mix between fixed and variable pay; performance goals; and equity-based plan costs;

➤

Avoid arrangements that risk “pay for failure”: This principle addresses the appropriateness of long or indefinite contracts, excessive severance packages, and guaranteed compensation;

➤

Maintain an independent and effective compensation committee: This principle promotes oversight of executive pay programs by directors with appropriate skills, knowledge, experience, and a sound process for compensation decision-making (e.g., including access to independent expertise and advice when needed);

➤

Provide shareholders with clear, comprehensive compensation disclosures: This principle underscores the importance of informative and timely disclosures that enable shareholders to evaluate executive pay practices fully and fairly;

➤

Avoid inappropriate pay to non-executive directors: This principle recognizes the interests of shareholders in ensuring that compensation to outside directors is reasonable and does not compromise their independence and ability to make appropriate judgments in overseeing managers’ pay and performance. At the market level, it may incorporate a variety of generally accepted best practices.

Advisory Votes on Executive Compensation—Management Proposals (Say-on-Pay)

➤

General Recommendation: Vote case-by-case on ballot items related to executive pay and practices, as well as certain aspects of outside director compensation.

Vote against Advisory Votes on Executive Compensation (Say-on-Pay or “SOP”) if:

➤

There is an unmitigated misalignment between CEO pay and company performance (pay for performance);

➤

The company maintains significant problematic pay practices;

➤

The board exhibits a significant level of poor communication and responsiveness to shareholders.

Vote against or withhold from the members of the Compensation Committee and potentially the full board if:

➤

There is no SOP on the ballot, and an against vote on an SOP would otherwise be warranted due to pay-for-performance misalignment, problematic pay practices, or the lack of adequate responsiveness on compensation issues raised previously, or a combination thereof;

➤

The board fails to respond adequately to a previous SOP proposal that received less than 70 percent support of votes cast;

➤

The company has recently practiced or approved problematic pay practices, such as option repricing or option backdating; or

➤

The situation is egregious.

Problematic Pay Practices related to Non-Performance-Based Compensation Elements

Pay elements that are not directly based on performance are generally evaluated case-by-case considering the context of a company's overall pay program and demonstrated pay-for-performance philosophy. Please refer to ISS' U.S. Compensation Policies FAQdocument for detail on specific pay practices that have been identified as potentially problematic and may lead to negative recommendations if they are deemed to be inappropriate or unjustified relative to executive pay best practices. The list below highlights the problematic practices that carry significant weight in this overall consideration and may result in adverse vote recommendations:

➤

Repricing or replacing of underwater stock options/SARS without prior shareholder approval (including cash buyouts and voluntary surrender of underwater options);

➤

Extraordinary perquisites or tax gross-ups;

➤

New or materially amended agreements that provide for:

➤

Excessive termination or CIC severance payments (generally exceeding 3 times base salary and average/target/most recent bonus);

➤

CIC severance payments without involuntary job loss or substantial diminution of duties ("single" or "modified single" triggers) or in connection with a problematic Good Reason definition;

➤

CIC excise tax gross-up entitlements (including "modified" gross-ups);

➤

Multi-year guaranteed awards that are not at risk due to rigorous performance conditions;

➤

Liberal CIC definition combined with any single-trigger CIC benefits;

➤

Insufficient executive compensation disclosure by externally-managed issuers (EMIs) such that a reasonable assessment of pay programs and practices applicable to the EMI's executives is not possible;

➤

Any other provision or practice deemed to be egregious and present a significant risk to investors.

Options Backdating

The following factors should be examined case-by-case to allow for distinctions to be made between “sloppy” plan administration versus deliberate action or fraud:

➤

Reason and motive for the options backdating issue, such as inadvertent vs. deliberate grant date changes;

➤

Duration of options backdating;

➤

Size of restatement due to options backdating;

➤

Corrective actions taken by the board or compensation committee, such as canceling or re-pricing backdated options, the recouping of option gains on backdated grants; and

➤

Adoption of a grant policy that prohibits backdating and creates a fixed grant schedule or window period for equity grants in the future.

Compensation Committee Communications and Responsiveness

Consider the following factors case-by-case when evaluating ballot items related to executive pay on the board’s responsiveness to investor input and engagement on compensation issues:

➤

Failure to respond to majority-supported shareholder proposals on executive pay topics; or

➤

Failure to adequately respond to the company's previous say-on-pay proposal that received the support of less than 70 percent of votes cast, taking into account:

➤

Disclosure of the specific concerns voiced by dissenting shareholders that led to the say-on-pay opposition;

➤

Disclosure of specific and meaningful actions taken to address shareholders’ concerns;

➤

Other recent compensation actions taken by the company;

➤

Whether the issues raised are recurring or isolated;

➤

The company's ownership structure; and

SOCIAL AND ENVIRONMENTAL ISSUES

Global Approach

Issues covered under the policy include a wide range of topics, including consumer and product safety, environment and energy, labor standards and human rights, workplace and board diversity, and corporate political issues. While a variety of factors goes into each analysis, the overall principle guiding all vote recommendations focuses on how the proposal may enhance or protect shareholder value in either the short or long term.

➤

General Recommendation: Generally vote case-by-case, examining primarily whether implementation of the proposal is likely to enhance or protect shareholder value. The following factors will be considered:

➤

If the issues presented in the proposal are more appropriately or effectively dealt with through legislation or government regulation;

➤

If the company has already responded in an appropriate and sufficient manner to the issue(s) raised in the proposal;

➤

Whether the proposal's request is unduly burdensome (scope or timeframe) or overly prescriptive;

➤

The company's approach compared with any industry standard practices for addressing the issue(s) raised by the proposal;

➤

Whether there are significant controversies, fines, penalties, or litigation associated with the company's environmental or social practices;

➤

If the proposal requests increased disclosure or greater transparency, whether reasonable and sufficient information is currently available to shareholders from the company or from other publicly available sources; and

➤

If the proposal requests increased disclosure or greater transparency, whether implementation would reveal proprietary or confidential information that could place the company at a competitive disadvantage.

Climate Change /Greenhouse Gas (GHG) Emissions

➤

General Recommendation: Generally vote for resolutions requesting that a company disclose information on the financial, physical, or regulatory risks it faces related to climate change on its operations and investments or on how the company identifies, measures, and manages such risks, considering:

➤

Whether the company already provides current, publicly-available information on the impact that climate change may have on the company as well as associated company policies and procedures to address related risks and/or opportunities;

➤

The company’s level of disclosure compared to industry peers; and

➤

Whether there are significant controversies, fines, penalties, or litigation associated with the company’s climate change-related performance.

Generally vote for proposals requesting a report on greenhouse gas (GHG) emissions from company operations and/or products and operations, unless:

➤

The company already discloses current, publicly-available information on the impacts that GHG emissions may have on the company as well as associated company policies and procedures to address related risks and/or opportunities;

➤

General Description of the Trust and the Fund

The Fund, as a series of the Trust, represents a beneficial interest in a separate portfolio of securities and other assets, with its own objectives and policies. Effective February 29, 2016, the Fund’s name was changed to its current name from First Trust Low Duration Mortgage Opportunities ETF.

The Trust or any series or class thereof may be terminated at any time by the Board of Trustees upon written notice to the shareholders.

Fund, the Trustees are required to reject the demand and the complaining shareholder may not proceed with the derivative action unless the shareholder is able to sustain the burden of proof to a court that the decision of the Trustees not to pursue The requested action was not a good faith exercise of their business judgment on behalf of the Fund. In making such a determination, a Trustee is not considered to have a personal financial interest by virtue of being compensated for his or her services as a Trustee. If a demand is rejected, the complaining shareholder will be responsible for the costs and expenses (including attorneys’ fees) incurred by the Fund in connection with the consideration of the demand under a number of circumstances. In addition, if a court determines that a derivative action was made without reasonable cause or for an improper purpose, or if a derivative or direct action is dismissed on the basis of a failure to comply with the procedural provisions relating to shareholder actions as set forth in the Declaration, or if a direct action is dismissed by a court for failure to state a claim, the shareholder bringing the action may be responsible for the Fund’s costs, including attorneys’ fees.

The Trust is not required to and does not intend to hold annual meetings of shareholders.

The Fund is advised by First Trust Advisors L.P. (the “Advisor” or “First Trust”).

Exchange Listing and Trading

As in the case of other stocks traded on the Exchange, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

Investment Objectives and Policies

The Prospectus describes the investment objectives and certain policies of the Fund. The following supplements the information contained in the Prospectus concerning the investment objectives and policies of the Fund.

(1)

The Fund may not issue senior securities, except as permitted under the 1940 Act.

(2)

The Fund may not borrow money, except that the Fund may (i) borrow money from banks for temporary or emergency purposes (but not for leverage or the purchase of investments) and (ii) engage in other transactions permissible under the 1940 Act that may involve a borrowing, provided that the combination of (i) and (ii) shall not exceed 33⅓% of the value of the Fund’s total assets (including the amount borrowed), less the Fund’s liabilities (other than borrowings).

(7)

The Fund’s investment objectives and the foregoing fundamental policies of the Fund may not be changed without the affirmative vote of the majority of the outstanding voting securities of the Fund. The 1940 Act defines a majority vote as the vote of the lesser of (i) 67% or more of the voting securities represented at a meeting at which more than 50% of the outstanding securities are represented; or (ii) more than 50% of the outstanding voting securities. With respect to the submission of a change in an investment policy to the holders of outstanding voting securities of the Fund, such matter shall be deemed to have been effectively acted upon with respect to the Fund if a majority of the outstanding voting securities of the Fund vote for the approval of such matter, notwithstanding that such matter has not been approved by the holders of a majority of the outstanding voting securities of any other series of the Trust affected by such matter.

The Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (a “Name Policy”) whereby the Fund, under normal market conditions, will invest at least 80% of its net assets in Mortgage-Related Instruments (as defined below).

Investment Strategies

The following information supplements the discussion of the Fund’s investment objectives, policies and strategies that appears in the Prospectus.

The Fund seeks to achieve its investment objectives by investing at least 60% of its net assets (including investment borrowings) in mortgage-related debt securities and other mortgage-related instruments (collectively, “Mortgage-Related Investments”). The Fund will be able to invest up to 40% of its net assets (including investment borrowings), in the aggregate, in (i) cash, cash equivalents and short-term investments (as described in the prospectus) and (ii) non-mortgage direct obligations of the U.S. government and other non-mortgage securities issued and/or guaranteed by Government Entities (as defined in the prospectus). Fund shareholders are entitled to 60 days’ notice prior to any change in these non-fundamental policies.

Types of Investments

Asset-Backed Securities ( “ABS” ). Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Asset-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities.

Cash Equivalents and Short-Term Investments. Normally, the Fund invests substantially all of its assets to meet its investment objective; however, for temporary or defensive purposes, the Fund may invest in fixed income investments and cash equivalents in order to provide income, liquidity and preserve capital. Under normal market conditions, for investment purposes, the Fund may invest in short-term debt securities, money market funds and other cash equivalents, or it may hold cash.

Cash equivalents and short-term investments held by the Fund may include, without limitation, the types of investments set forth below:

(1)

The Fund may invest in U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government securities include securities that are issued or guaranteed by the United States Treasury, by various agencies of the U.S. government, or by various instrumentalities that have been established or sponsored by the U.S. government. U.S. Treasury securities are backed by the “full faith and credit” of the United States. Securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. Some of the U.S. government agencies that issue or guarantee securities include the Export-Import Bank of the United States, the Farmers Home Administration, the Federal Housing Administration, the Maritime Administration, the Small Business Administration and The Tennessee Valley Authority. An instrumentality of the U.S. government is a government agency organized under federal charter with government supervision. Instrumentalities issuing or guaranteeing securities include, among others, the Federal Home Loan Banks, the Federal Land Banks, the Central Bank for Cooperatives, Federal Intermediate Credit Banks and FNMA. In the case of those U.S. government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. In addition, the Fund may invest in sovereign debt obligations of non-U.S. countries. A sovereign debtor’s willingness or ability to repay principal and interest in a timely manner may be affected by a number of factors, including its cash flow situation, the extent of its non-U.S. reserves, the availability of sufficient non-U.S. exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders and the political constraints to which it may be subject.

(4)

agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, however, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. The portfolio managers monitor the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The portfolio managers do so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(5)

(6)

The Fund may invest in commercial paper, which are short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for the notes. However, they are redeemable by the Fund at any time. The Fund’s portfolio managers will consider the financial condition of the corporation (e.g., earning power, cash flow and other liquidity ratios) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. The Fund may invest in commercial paper only if it has received the highest rating from at least one nationally recognized statistical rating organization or, if unrated, judged by First Trust to be of comparable quality.

(7)

Derivatives. The Fund may hold listed derivatives, including futures, options and swaps on commodities, currencies and financial instruments, or a basket or index of any of the foregoing. Additionally, the Fund may hold derivatives traded over-the-counter ("OTC”), including forwards, swaps, options and swaps on commodities, currencies and financial instruments,

or a basket or index of any of the foregoing. However, on both an initial and continuing basis, no more than 20% of the assets in the Fund's portfolio may be invested in OTC derivatives. Derivatives are financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate or index, and may relate to, among other things, interest rates, currencies or currency exchange rates. The Fund may, but is not required to, use derivative instruments for risk management purposes or as part of its investment strategies. The Fund will use derivative instruments primarily to hedge interest rate risk, actively manage interest rate exposure, hedge foreign currency risk and actively manage foreign currency exposure. The Fund may also use derivative instruments to enhance returns, as a substitute for, or to gain exposure to, a position in an underlying asset, to reduce transaction costs, to maintain full market exposure (which means to adjust the characteristics of its investments to more closely approximate those of the markets in which it invests), to manage cash flows or to preserve capital. The Fund’s investments in derivative instruments will not be used to seek to achieve a multiple or inverse multiple of an index. The use of the Fund’s derivative transactions may allow the Fund to obtain net long or short exposures to selected interest rates or durations. These derivatives may also be used to hedge risks associated with the Fund’s other portfolio investments.

High Yield Securities. The Fund may invest in securities that are rated below investment grade, commonly referred to as “junk” bonds, at the time of purchase. The ratings of a rating agency represent its opinion as to the quality of securities it undertakes to rate. Ratings are not absolute standards of quality; consequently, securities with the same maturity, duration, coupon and rating may have different yields. For purposes of determining whether a security is below investment grade, the highest available rating will be considered. If a security owned by the Fund is subsequently downgraded, the Fund will not be required to dispose of such security. If a downgrade occurs, the Advisor will consider what action, including the sale of such security, is in the best interests of the Fund. The Credit Rating Definitions, as published by the three major rating agencies, are set forth in Exhibit B to this SAI.

Illiquid Securities. The Fund may invest in illiquid securities (i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For purposes of this restriction, illiquid securities may include, but are not limited to, certain restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the 1933 Act, and repurchase agreements with maturities in excess of seven days, among others. However, the Fund will not acquire illiquid securities if, as a result, such securities would comprise more than 15% of the value of the Fund’s net assets. The Advisor, subject to oversight by the Board of Trustees, has the ultimate authority to determine, to the extent permissible under the federal securities laws, which securities are liquid or illiquid for purposes of this 15% limitation under the Fund’s liquidity risk management program, adopted pursuant to Rule 22e-4 under the 1940 Act.

Investment Companies. The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”). An ETF is a fund that holds a portfolio of securities and trades on a securities exchange and its shares may, at times, trade at a premium or discount to its net asset value. As a shareholder in a pooled investment vehicle, the Fund will bear its ratable share of that vehicle’s expenses, and would remain subject to payment of the Fund’s management fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other pooled investment vehicles. In addition, the Fund will incur brokerage costs when purchasing and selling shares of ETFs and

closed-end investment companies. Other pooled investment vehicles may be leveraged, and the net asset value and market value of their securities will therefore be more volatile and the yield to shareholders will tend to fluctuate more than the yield of unleveraged pooled investment vehicles.

Mortgage-Backed Securities. The Fund normally expects to invest in Mortgage-Related Investments tied to residential and commercial mortgages, including, among other things, residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”). The Fund will limit its investment in Mortgage-Related Investments that are not issued or guaranteed by government entities to 20% of its net assets. Mortgage-backed securities represent an interest in a pool of mortgage loans made by banks and other financial institutions to finance purchases of homes, commercial buildings and other real estate. The individual mortgage loans are packaged or “pooled” together for sale to investors. As the underlying mortgage loans are paid off, investors receive principal and interest payments. Mortgage-backed securities may be fixed-rate or adjustable-rate mortgage-backed securities (“ARMS”). Certain mortgage-backed securities (including RMBS and CMBS), where mortgage payments are divided up between paying the loan’s principal and paying the loan’s interest, are referred to as stripped mortgage-backed securities (“SMBS”). Further, mortgage-backed securities can also be categorized as collateralized mortgage obligations (“CMOs”) or real estate mortgage investment conduits (“REMICs”) where they are divided into multiple classes with each class being entitled to a different share of the principal and/or interest payments received from the pool of underlying assets.

The mortgage-backed securities in which the Fund will invest may be, but are not required to be, issued or guaranteed by the U.S. government or its agencies or instrumentalities, such as Government National Mortgage Association (“Ginnie Mae”), and U.S. government-sponsored entities, such as that Federal National Mortgage Association (“Fannie Mae”), and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The Fund may invest in callable agency securities, which give the issuer (the U.S. government agency) the right to redeem the security prior to maturity. Government agency or instrumentality securities have different levels of credit support. For example, Ginnie Mae securities carry a guarantee as to the timely repayment of principal and interest that is backed by the full faith and credit of the U.S. government. However, the full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Mae securities or to the net asset value, trading price or performance of the Fund, which will vary with changes in interest rates and other market conditions. Fannie Mae and Freddie Mac pass-through mortgage certificates are backed by the credit of the respective instrumentality and are not guaranteed by the U.S. government. Other securities issued by government agencies or instrumentalities, including government-sponsored entities, may only be backed by the creditworthiness of the issuing institution, not the U.S. government, or the issuers may have the right to borrow from the U.S. Treasury to meet their obligations. Many mortgage-backed securities are pass-through securities, which means they provide investors with monthly payments consisting of a pro rata share of both regular interest and principal payments as well as unscheduled prepayments on the underlying mortgage loans. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately. Adjustable-rate mortgage-backed securities include ARMS and other mortgage-backed securities with interest rates that adjust periodically to reflect prevailing market rates.

Mortgage Dollar Rolls. The Fund may invest, without limitation, in mortgage dollar rolls. In a mortgage dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (i.e., same type, coupon and maturity) securities on a future date. During the period between a sale and repurchase, the Fund will forgo principal and interest paid on the mortgage-backed securities. The Fund will earn or lose money on a mortgage dollar roll from any difference between the sale price and the future purchase price. In a sale and repurchase, the Fund will also earn money on the interest earned on the cash proceeds of the initial sale. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Advisor. Mortgage dollar rolls simulate the investment in a mortgage-backed security, while generally reducing the administrative and cost burdens of owning the mortgage-backed security directly. Investments in mortgage dollar rolls will generally expose the Fund to counter-party risk.

Short Sales. The Fund may take short positions in securities, which are often referred to as “short sales”; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets. A short sale is a sale of a security the Fund has borrowed, with the expectation that the security will underperform the market. To settle the short sale transaction, the Fund buys the same security at a later date and returns it to the lender of the security. The Fund makes money on a short position if the market price of the security goes down after the short sale or if the market price of the securities it buys with the proceeds of the short sale increases more than that of the security sold short. Conversely, if the price of the security sold short goes up after the short sale, the Fund loses money because it has to pay more to replace the borrowed security than it received when it sold the security short. Short-selling is considered “leverage” and may involve substantial risk.

TBA Transactions. The Fund may invest in to-be-announced transactions (“TBA Transactions”). A TBA Transaction is a method of trading mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely accepted guidelines that establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price. The actual pools delivered generally are determined two days prior to the settlement date.

U.S. Government Securities. The Fund may invest in U.S. government securities. U.S. government securities include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government, or by various instrumentalities, which have been established or sponsored by the U.S. government. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

Hedging Strategies

General Description of Hedging Strategies

The Fund may engage in hedging activities or other investment in derivative instruments, as described above. The Fund may utilize a variety of financial instruments, including exchange-listed options on U.S. Treasury securities, exchange-listed options on U.S. Treasury futures contracts and exchange-listed U.S. Treasury futures contracts to attempt to hedge the Fund’s holdings.

Hedging or derivative instruments on securities generally are used to hedge against price movements in one or more particular securities positions that the Fund owns or intends to acquire. Such instruments may also be used to “lock-in” realized but unrecognized gains in the value of portfolio securities. Hedging instruments on stock indices, in contrast, generally are used to hedge against price movements in broad market sectors in which the Fund has invested or expects to invest. Hedging strategies, if successful, can reduce the risk of loss by wholly or partially offsetting the negative effect of unfavorable price movements in the investments being hedged. However, hedging strategies can also reduce the opportunity for gain by offsetting the positive effect of favorable price movements in the hedged investments. The use of hedging instruments is subject to applicable regulations of the SEC, the several options and futures exchanges upon which they are traded, the Commodity Futures Trading Commission (the “CFTC”) and various state regulatory authorities. In addition, the Fund’s ability to use hedging instruments may be limited by tax considerations.

General Limitations on Futures and Options Transactions

The Fund limits its direct investments in futures, options on futures and swaps to the extent necessary for First Trust to claim the exclusion from regulation as a “commodity pool operator” with respect to the Fund under CFTC Rule 4.5, as such rule may be amended from time to time. Under Rule 4.5 as currently in effect, the Fund limits its trading activity in futures, options on futures and swaps (excluding activity for “bona fide hedging purposes,” as defined by the CFTC) such that it meets one of the following tests: (i) aggregate initial margin and premiums required to establish its futures, options on futures and swap positions do not exceed 5% of the liquidation value of the Fund’s portfolio, after taking into account unrealized profits and losses on such positions; or (ii) aggregate net notional value of its futures, options on futures and swap positions does not exceed 100% of the liquidation value of the Fund’s portfolio, after taking into account unrealized profits and losses on such positions.

First Trust has filed a notice of eligibility for exclusion from the definition of the term “commodity pool operator” with respect to the Fund with the National Futures Association, the futures industry’s self-regulatory organization. If First Trust were no longer able to claim the exclusion for the Fund, First Trust would be required to register as a “commodity pool operator,” and the Fund and First Trust would be subject to regulation under the Commodity Exchange Act (the “CEA”).

The foregoing limitations are non-fundamental policies of the Fund and may be changed without shareholder approval as regulatory agencies permit.

Asset Coverage for Futures and Options Positions

segregated custodial account in the amount prescribed. Securities earmarked or held in a segregated account cannot be sold while the futures or options position is outstanding, unless replaced with other permissible assets, and will be marked-to-market daily.

Certain Considerations Regarding Options

There is no assurance that a liquid secondary market on an options exchange will exist for any particular option, or at any particular time, and for some options no secondary market on an exchange or elsewhere may exist. If the Fund is unable to close out a call option on securities that it has written before the option is exercised, the Fund may be required to purchase the optioned securities in order to satisfy its obligation under the option to deliver such securities. If the Fund is unable to effect a closing sale transaction with respect to options on securities that it has purchased, it would have to exercise the option in order to realize any profit and would incur transaction costs upon the purchase and sale of the underlying securities.

The writing and purchasing of options is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Imperfect correlation between the options and securities markets may detract from the effectiveness of attempted hedging. Options transactions may result in significantly higher transaction costs and portfolio turnover for the Fund.

Futures Contracts

The Fund may enter into futures contracts and the Fund’s hedging activities may include sales of futures as an offset against the effect of expected declines in stock prices and purchases of futures as an offset against the effect of expected increases in stock prices. The Fund will not enter into futures contracts that are prohibited under the CEA and will, to the extent required by regulatory authorities, enter only into futures contracts that are traded on futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading are regulated under the CEA by the CFTC.

An interest rate futures contract provides for the future sale by one party and purchase by another party of a specified amount of a specific financial instrument (e.g., a debt security) or currency for a specified price at a designated date, time and place. An index futures contract is an agreement pursuant to which the parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index futures contract was originally written. Transaction costs are incurred when a futures contract is bought or sold and margin deposits must be maintained. A futures contract may be satisfied by delivery or purchase, as the case may be, of the instrument or by payment of the change in the cash value of the index. More commonly, futures contracts are closed out prior to delivery by entering into an offsetting transaction in a matching futures contract. Although the value of an index might be a function of the value of certain specified securities, no physical delivery of those securities is made. If the offsetting purchase price is less than the original sale price, a gain will be realized. Conversely, if the offsetting sale price is more than the original purchase price, a gain will be realized; if it is less, a loss will be realized. The transaction costs must also be included in these calculations. There can be no assurance, however, that the Fund will be able to enter into an offsetting transaction with respect to a particular futures contract at a particular time. If the Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain the margin deposits on the futures contract.

Margin is the amount of funds that must be deposited by the Fund with its custodian in a segregated account in the name of the futures commission merchant in order to initiate futures trading and to maintain the Fund’s open positions in futures contracts. A margin deposit is intended to ensure the Fund’s performance of the futures contract.

The margin required for a particular futures contract is set by the exchange on which the futures contract is traded and may be significantly modified from time to time by the exchange during the term of the futures contract. Futures contracts are customarily purchased and sold on margins that may range upward from less than 5% of the value of the futures contract being traded.

If the price of an open futures contract changes (by increase in the case of a sale or by decrease in the case of a purchase) so that the loss on the futures contract reaches a point at which the margin on deposit does not satisfy margin requirements, the broker will require an increase in the margin. However, if the value of a position increases because of favorable price changes in the futures contract so that the margin deposit exceeds the required margin, the broker will pay the excess to the Fund. In computing daily net asset value, the Fund will mark to market the current value of its open futures contracts. The Fund expects to earn interest income on its margin deposits.

Because of the low margin deposits required, futures trading involves an extremely high degree of leverage. As a result, a relatively small price movement in a futures contract may result in immediate and substantial loss, as well as gain, to the investor. For example, if at the time of purchase 10% of the value of the futures contract is deposited as margin, a subsequent 10% decrease in the value of the futures contract would result in a total loss of the margin deposit, before any deduction for the transaction costs, if the account were then closed out. A 15% decrease would result in a loss equal to 150% of the original margin deposit, if the future contracts were closed out. Thus, a purchase or sale of a futures contract may result in losses in excess of the amount initially invested in the futures contract. However, the Fund would presumably have sustained comparable losses if, instead of the futures contract, it had invested in the underlying financial instrument and sold it after the decline.

Most U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The day limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of futures contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some investors to substantial losses.

There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a futures position. The Fund would continue to be required to meet margin requirements until the position is closed, possibly resulting in a decline in the Fund’s net asset value. In addition, many of the contracts discussed above are relatively new instruments without a significant trading history. As a result, there can be no assurance that an active secondary market will develop or continue to exist.

Options on Futures

The Fund may also purchase or write put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option may be closed out by an offsetting purchase or sale of a futures option of the same series.

The Fund may use options on futures contracts in connection with hedging strategies. Generally, these strategies would be applied under the same market and market sector conditions in which the Fund uses put and call options on securities or indices. The purchase of put options on futures contracts is analogous to the purchase of puts on securities or indices so as to hedge the Fund’s securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities that are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund’s holdings of securities. If the price when the option is exercised is above the exercise price, however, the Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Fund intends to acquire.

As with investments in futures contracts, the Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by the Fund. The Fund will earmark or set aside in a segregated account at the Fund’s custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be earmarked or placed in the segregated account whenever the total value of the earmarked or segregated assets falls below the amount due on the underlying obligation.

and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to the option. For additional information, see “Futures Contracts.” Certain characteristics of the futures market might increase the risk that movements in the prices of futures contracts or options on futures contracts might not correlate perfectly with movements in the prices of the investments being hedged. For example, all participants in the futures and options on futures contracts markets are subject to daily variation margin calls and might be compelled to liquidate futures or options on futures contracts positions whose prices are moving unfavorably to avoid being subject to further calls. These liquidations could increase the price volatility of the instruments and distort the normal price relationship between the futures or options and the investments being hedged. Also, because of initial margin deposit requirements, there might be increased participation by speculators in the futures markets. This participation also might cause temporary price distortions. In addition, activities of large traders in both the futures and securities markets involving arbitrage, “program trading,” and other investment strategies might result in temporary price distortions.

Swap Agreements

A swap is a financial instrument that typically involves the exchange of cash flows between two parties on specified dates (settlement dates), where the cash flows are based on agreed-upon prices, rates, indices, etc. The nominal amount on which the cash flows are calculated is called the notional amount. Swaps are individually negotiated and structured to include exposure to a variety of different types of investments or market factors, such as interest rates, non-U.S. currency rates, mortgage securities, corporate borrowing rates, security prices, indexes or inflation rates.

Swap agreements may increase or decrease the overall volatility of the investments of the Fund and its share price. The performance of swap agreements may be affected by a change in the specific interest rate, currency, or other factors that determine the amounts of payments due to and from the Fund. If a swap agreement calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if the counterparty’s creditworthiness declines, the value of a swap agreement would be likely to decline, potentially resulting in losses.

Generally, swap agreements have a fixed maturity date that will be agreed upon by the parties. The agreement can be terminated before the maturity date only under limited circumstances, such as default by one of the parties or insolvency, among others, and can be transferred by a party only with the prior written consent of the other party. The Fund may be able to eliminate its exposure under a swap agreement either by assignment or by other disposition, or by entering into an offsetting swap agreement with the same party or a similarly creditworthy party. If the counterparty is unable to meet its obligations under the contract, declares bankruptcy, defaults or becomes insolvent, the Fund may not be able to recover the money it expected to receive under the contract.

A swap agreement can be a form of leverage, which can magnify the Fund’s gains or losses. In order to reduce the risk associated with leveraging, the Fund may cover its current obligations under swap agreements according to guidelines established by the SEC. If the Fund enters into a swap agreement on a net basis, it will earmark assets with a daily value at least equal to the excess, if any, of the Fund’s accrued obligations under the swap agreement over the accrued amount the Fund is entitled to receive under the agreement. If the Fund enters into a swap agreement on other than a net basis, it will earmark assets with a value equal to the full amount of the Fund’s accrued obligations under the agreement.

Equity Swaps. In a typical equity swap, one party agrees to pay another party the return on a stock, stock index or basket of stocks in return for a specified interest rate. By entering into an equity index swap, for example, the index receiver can gain exposure to stocks making up the index of securities without actually purchasing those stocks. Equity index swaps involve not only the risk associated with investment in the securities represented in the index, but also the risk that the performance of such securities, including dividends, will not exceed the return on the interest rate that the Fund will be committed to pay.

Interest Rate Swaps. Interest rate swaps are financial instruments that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future. Some of the different types of interest rate swaps are “fixed-for floating rate swaps,” “termed basis swaps” and “index amortizing swaps.” Fixed-for floating rate swaps involve the exchange of fixed interest rate cash flows for floating rate cash flows. Termed basis swaps entail cash flows to both parties based on floating interest rates, where the interest rate indices are different. Index amortizing swaps are typically fixed-for floating swaps where the notional amount changes if certain conditions are met. Like a traditional investment in a debt security, the Fund could lose money by investing in an interest rate swap if interest rates change adversely. For example, if the Fund enters into a swap where it agrees to exchange a floating rate of interest for a fixed rate of interest, the Fund may have to pay more money than it receives. Similarly, if the Fund enters into a swap where it agrees to exchange a fixed rate of interest for a floating rate of interest, the Fund may receive less money than it has agreed to pay.

Currency Swaps. A currency swap is an agreement between two parties in which one party agrees to make interest rate payments in one currency and the other promises to make interest rate payments in another currency. The Fund may enter into a currency swap when it has one currency and desires a different currency. Typically the interest rates that determine the currency swap payments are fixed, although occasionally one or both parties may pay a floating rate of interest. Unlike an interest rate swap, however, the principal amounts are exchanged at the beginning of the contract and returned at the end of the contract. Changes in non-U.S. exchange rates and changes in interest rates, as described above, may negatively affect currency swaps.

Credit Default Swaps. A credit default swap is similar to an insurance contract in that it provides the buyer with protection against specific risks. Most often, corporate bond investors buy credit default swaps for protection against a default by the issuer of the corporate bond, but these flexible instruments can be used in many ways to customize exposure to corporate credit. Credit default swap agreements can mitigate risks in bond investing by transferring a given risk from one party to another without transferring the underlying bond or other credit asset. In a credit default swap agreement, one party “sells” risk and the counterparty “buys” that risk. The “seller” of credit risk, who also tends to own the underlying credit asset, pays a periodic fee to the risk “buyer.” In return, the risk “buyer” agrees to pay the “seller” a set amount if there is a default, or a credit event.

The Fund’s use of credit default swap agreements exposes the Fund to additional risks, including but not limited to, the credit and liquidity risk of a counterparty. If the credit quality of any such counterparty deteriorates, such counterparty may default on its obligations to make payments under the swap agreement. The Fund may also be exposed to liquidity risk because the market for credit default swaps are relatively illiquid and the Fund will generally not be permitted to terminate or assign its credit default swaps without the consent of the related counterparty and accordingly may not be able to terminate or assign such credit default swaps in a timely fashion and for a fair price, potentially restricting its ability to take advantage of market opportunities.

Lending of Portfolio Securities

In order to generate additional income, as a non-principal investment strategy, First Trust is authorized to select the First Trust Funds, including the Fund, with notice to the Board of Trustees, to lend portfolio securities representing up to 33⅓% of the value of its total assets to broker-dealers, banks or other institutional borrowers of securities. As with other extensions of credit, there may be risks of delay in recovery of the securities or even loss of rights in the collateral should the borrower of the securities fail financially. However, such First Trust Funds will only enter into loan arrangements with broker-dealers, banks or other institutions which First Trust has determined are creditworthy under guidelines approved by the Board of Trustees. The First Trust Funds will pay a portion of the income earned on the lending transaction to the placing broker and may pay administrative and custodial fees in connection with these loans. First Trust may select the First Trust Fund to participate in the securities lending program, at its discretion with notice to the Board of Trustees.

pays the lending First Trust Fund any dividends or interest paid on the securities. Loans are subject to termination at any time by the lending First Trust Fund or the borrower. While a First Trust Fund does not have the right to vote securities on loan, it would terminate the loan and regain the right to vote if that were considered important with respect to the investment. When a First Trust Fund lends portfolio securities to a borrower, payments in lieu of dividends made by the borrower to the First Trust Fund will not constitute “qualified dividends” taxable at the same rate as long-term capital gains, even if the actual dividends would have constituted qualified dividends had the First Trust Fund held the securities. Please see "Securities Lending Risk" below for a description of the risks associated with securities lending activities.

Investment Risks

The following risk disclosure supplements the discussion of the Fund’s investment risks that appears in the Prospectus.

Overview

Agency Mortgage-Related Securities Risk

Credit Rating Agency Risk

Derivatives Risk

The use of derivatives, such as options, presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivatives. In addition, when the Fund invests in certain derivative securities, including, but not limited to, when-issued securities, forward commitments, futures contracts and interest rate swaps, the Fund is effectively leveraging its investments, which could result in exaggerated changes in the net asset value of the Fund’s shares and can result in losses that exceed the amount originally invested. The success of the Advisor’s derivatives strategies will depend on its ability to assess and predict the impact of market or economic developments on the underlying asset, index or rate and the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions. Liquidity risk exists when a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Certain specific risks associated with an investment in derivatives may include: market risk, credit risk, correlation risk, liquidity risk, legal risk and systemic or “interconnection” risk, as specified below.

(1)

Market Risk. Market risk is the risk that the value of the underlying assets may go up or down. Adverse movements in the value of an underlying asset can expose the Fund to losses. Derivative instruments may include elements of leverage and, accordingly, fluctuations in the value of the derivative instrument in relation to the underlying asset may be magnified. The successful use of derivative instruments depends upon a variety of factors, particularly the portfolio managers’ ability to predict movements of the securities, currencies, and commodities markets, which may require different skills than predicting changes in the prices of individual securities. There can be no assurance that any particular strategy adopted will succeed. A decision to engage in a derivative transaction will reflect the portfolio managers’ judgment that the derivative transaction will provide value to the Fund and its shareholders and is consistent with the Fund’s objectives, investment limitations and operating policies. In making such a judgment, the portfolio managers will analyze the benefits and risks of the derivative transactions and weigh them in the context of the Fund’s overall investments and investment objectives.

(4)

Liquidity Risk. Liquidity risk is the risk that a derivative instrument cannot be sold, closed out, or replaced quickly at or very close to its fundamental value. Generally, exchange contracts are very liquid because the exchange clearinghouse is the counterparty of every contract. OTC transactions are less liquid than exchange-traded derivatives since they often can only be closed out with the other party to the transaction. The Fund might be required by applicable regulatory requirements to maintain assets as “cover,” maintain segregated accounts, and/or make margin payments when it takes positions in derivative instruments involving obligations to third parties (i.e., instruments other than purchase options). If the Fund is unable to close out its positions in such instruments, it might be required to continue to maintain such assets or accounts or make such payments until the position expires, matures, or is closed out. These requirements might impair the Fund’s ability to sell a security or make an investment at a time when it would otherwise be favorable to do so, or require that the Fund sell a portfolio security at a disadvantageous time. The Fund’s ability to sell or close out a position in an instrument prior to expiration or maturity depends upon the existence of a liquid secondary market or, in the absence of such a market, the ability and willingness of the counterparty to enter into a transaction closing out the position. Due to liquidity risk, there is no assurance that any derivatives position can be sold or closed out at a time and price that is favorable to the Fund.

(5)

(6)

Systemic or “Interconnection” Risk. Systemic or “interconnection” risk is the risk that a disruption in the financial markets will cause difficulties for all market participants. In other words, a disruption in one market will spill over into other markets, perhaps creating a chain reaction. Much of the OTC derivatives market takes place among the OTC dealers themselves, thus creating a large interconnected web of financial obligations. This interconnectedness raises the possibility that a default by one large dealer could create losses for other dealers and destabilize the entire market for OTC derivative instruments.

Fixed Income Securities Risk

An investment in the Fund also involves risk associated with an investment in fixed income securities including the risk that certain of the securities in the Fund may not have the benefit of covenants that would prevent the issuer from engaging in capital restructurings or borrowing transactions in connection with corporate acquisitions, leveraged buyouts or restructurings that could have the effect of reducing the ability of the issuer to meet its payment obligations and might result in increased credit risk. In addition, certain of the securities may be redeemed or prepaid by the issuer, resulting in lower interest payments received by the Fund and reduced distributions to shareholders.

Information Risk

There is typically less publicly available information concerning Mortgage-Related Investments than other types of fixed income investments. As a result, the Fund generally will be dependent on reports and other information provided by the entity pooling the Mortgage-Related Investments or the obligor, either directly or through an intermediary, to evaluate the obligor’s creditworthiness or to determine the obligor’s compliance with the covenants and other terms of the loan agreement. Such reliance may make investments in Mortgage-Related Investments more susceptible to fraud than other types of investments.

Leverage Risk

Leverage risk is the risk that the Fund may be more volatile than if it had not been leveraged due to leverage’s tendency to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio. The use of leverage may also cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements.

Liquidity Risk

Whether or not the securities held by the Fund are listed on a securities exchange, the principal trading market for certain of the securities may be in the over-the-counter (“OTC”) market. As a result, the existence of a liquid trading market for such securities may depend on whether dealers will make a market in the securities. There can be no assurance that a market will be made for any of the securities, that any market for such securities will be maintained or that there will be sufficient liquidity of the securities in any markets made. The price at which such securities are held by the Fund will be adversely affected if trading markets for the securities are limited or absent.

Listing Standards Risk

The Fund is required to comply with listing requirements adopted by the Exchange. Non-compliance with such requirements may result in the Fund’s shares being delisted by the Exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs and could result in negative tax consequences for its shareholders.

Market Risk

as well as the economies of individual countries or regions, the financial performance of individual companies, sectors and industries, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests and negatively impact the Fund’s investment return. For example, an outbreak of a respiratory disease designated as COVID-19 was first detected in China in December 2019 and subsequently spread internationally. The transmission of COVID-19 and efforts to contain its spread have resulted in international, national and local border closings and other significant travel restrictions and disruptions, significant disruptions to business operations, supply chains and customer activity, event cancellations and restrictions, service cancellations, reductions and other changes, significant challenges in healthcare service preparation and delivery, and quarantines, as well as general concern and uncertainty that has negatively affected the economic environment. These impacts also have caused significant volatility and declines in global financial markets, which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession.

Regulatory Changes

To the extent that legislation or state or federal regulators that regulate certain financial institutions impose additional requirements or restrictions with respect to the ability of such institutions to make loans, particularly in connection with highly leveraged transactions, the availability of Mortgage-Related Securities for investment may be adversely affected. Furthermore, such legislation or regulation could depress the market value of Mortgage-Related Securities held by the Fund.

As of December 31, 2020, the officers and Trustees, in the aggregate, owned less than 1% of the shares of the Fund.

The table set forth as Exhibit A shows the percentage ownership of each person or “group” (as that term is used in Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) who, based on the securities position listing reports as of January 31, 2021, owned of record, or is known by the Trust to have owned of record or beneficially, 5% or more of the shares of the Fund (the “Principal Holders”). A control person is one who owns, either directly or indirectly, more than 25% of the voting securities of the Fund or acknowledges the existence of control. A party that controls the Fund may be able to significantly influence the outcome of any item presented to shareholders for approval.

and administrative services, and permits any of its officers or employees to serve without compensation as Trustees or officers of the Trust if elected to such positions.

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the “Investment Management Agreement”), First Trust manages the investment of the Fund’s assets and is responsible for paying all expenses of the Fund, excluding the fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions, acquired fund fees and expenses, if any, and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.65% of its average daily net assets.

Under the Investment Management Agreement, First Trust shall not be liable for any loss sustained by reason of the purchase, sale or retention of any security, whether or not such purchase, sale or retention shall have been based upon the investigation and research made by any other individual, firm or corporation, if such recommendation shall have been selected with due care and in good faith, except loss resulting from willful misfeasance, bad faith or gross negligence on the part of First Trust in the performance of its obligations and duties, or by reason of its reckless disregard of its obligations and duties. The Investment Management Agreement terminates automatically upon assignment and is terminable at any time without penalty as to the Fund by the Board of Trustees, including a majority of the Independent Trustees, or by vote of the holders of a majority of the Fund’s outstanding voting securities on 60 days’ written notice to First Trust, or by First Trust on 60 days’ written notice to the Fund.
The following table sets forth the unitary fee paid by the Fund to First Trust for the specified periods.

Amount of Unitary Fees
Fiscal Year Ended October 31,

$33,259,927	$17,574,335	$8,167,169

Portfolio Managers. The portfolio managers are primarily and jointly responsible for the day-to-day management of the Fund. There are currently two portfolio managers, as follows:

Name	Position with First Trust	Length of Service with First Trust	Principal Occupation During Past Five Years
James Snyder	Senior Vice President and Portfolio Manager	Since 2013	Vice President and Portfolio Manager (2013 to present), First Trust Portfolios L.P.; Senior Portfolio Manager (2013 to 2013), Fort Sheridan Advisors LLC; Senior Trader (2011 to 2012)
Jeremiah Charles	Senior Vice President and Portfolio Manager	Since 2013	Vice President and Portfolio Manager ( 2013 to present), First Trust Portfolios L.P.; Vice President (2011 to 2013), CRT Capital Group LLC

Mr. Snyder is a Portfolio Manager for the First Trust Securitized Products Group. Prior to joining First Trust in 2013, Mr. Snyder worked as a Senior Portfolio Manager at Fort Sheridan Advisors where he managed mortgage portfolios for institutional clients. Mr. Snyder has led several mortgage trading and portfolio groups at Deerfield Capital, Spyglass Capital & Trading and American Express Financial Advisors. Mr. Snyder managed AXP Federal Income Fund and developed mortgage trading strategies for Spyglass Capital and Deerfield’s Mortgage REIT and Opportunity Fund. Mr. Snyder holds a B.S. and M.A. in Economics from DePaul University and an MBA from the University of Chicago Booth School of Business.

Mr. Charles is a Portfolio Manager for the First Trust Securitized Products Group. Prior to joining First Trust in 2013, Mr. Charles worked as a Vice President of Mortgage Product Sales for CRT Capital where he advised pension funds, hedge funds and institutional money managers. Before joining CRT in 2011, Mr. Charles spent six years with Deerfield Capital Management LLC as a Senior Vice President and Senior Portfolio Manager for the Mortgage Trading team. Mr. Charles began his professional career as an Analyst at Piper Jaffray. Mr. Charles holds a B.S. in Finance from the Leeds School of Business at the University of Colorado and a M.S. in Real Estate Finance with Honors from the Charles H. Kellstadt Graduate School of Business at DePaul University.

As of October 31, 2020, Mr. Snyder beneficially owned shares of the Fund in the amount of $1-$10,000 and Mr. Charles beneficially owned shares of the Fund in the amount of $10,001-$50,000.

Accounts Managed by Portfolio Managers

The portfolio managers manage the investment vehicles (other than the Funds of the Trust) with the number of accounts and assets, as of the fiscal year ended October 31, 2020, set forth in the table below:

Portfolio Manager	Registered Investment Companies Number of Accounts ($ Assets)	Other Pooled Investment Vehicles Number of Accounts ($ Assets)	Other Accounts Number of Accounts ($ Assets)
James Snyder	5 ($5,301,977,221)	N/A	N/A
Jeremiah Charles	5 ($5,301,977,221)	N/A	N/A

Conflicts. None of the accounts managed by the portfolio managers pays an advisory fee that is based upon the performance of the account. In addition, First Trust believes that there are no material conflicts of interest that may arise in connection with the portfolio managers’ management of the Fund's investments and the investments of the other accounts managed by the portfolio managers. However, because the investment strategy of the Fund and the investment strategies of many of the other accounts managed by the portfolio managers are based on fairly mechanical investment processes, the portfolio managers may recommend that certain clients sell and other clients buy a given security at the same time. In addition, because the investment strategies of the Fund and other accounts managed by the portfolio managers generally result in the clients investing in readily available securities, the Advisor believes that there should not be material conflicts in the allocation of investment opportunities between the Fund and other accounts managed by the portfolio managers.

Brokerage Allocations

First Trust is responsible for decisions to buy and sell securities for the Fund and for the placement of the Fund’s securities business, the negotiation of the commissions to be paid on brokered transactions, the prices for principal trades in securities, and the allocation of portfolio brokerage and principal business. It is the policy of First Trust to seek the best execution at the best security price available with respect to each transaction, and with respect to brokered transactions in light of the overall quality of brokerage and research services provided to First Trust and its clients. The best price to the Fund means the best net price without regard to the mix between purchase or sale price and commission, if any. Purchases may be made from underwriters, dealers and, on occasion, the issuers. Commissions will be paid on the Fund’s futures and options transactions, if any. The purchase price of portfolio securities purchased from an underwriter or dealer may include underwriting commissions and dealer spreads. The Fund may pay markups on principal transactions. In selecting broker-dealers and in negotiating commissions, First Trust considers, among other things, the firm’s reliability, the quality of its execution services on a continuing basis and its financial condition. Fund portfolio transactions may be effected with broker-dealers who have assisted investors in the purchase of shares.

Trust determines in good faith that the amount of such commissions is reasonable in relation to the value of the research information and brokerage services provided by such broker to First Trust or the Trust. In addition, First Trust must determine that the research information received in this manner provides the Fund with benefits by supplementing the research otherwise available to the Fund. The Investment Management Agreement provides that such higher commissions will not be paid by the Fund unless the Advisor determines in good faith that the amount is reasonable in relation to the services provided. The investment advisory fees paid by the Fund to First Trust under the Investment Management Agreement would not be reduced as a result of receipt by First Trust of research services.

First Trust places portfolio transactions for other advisory accounts advised by it, and research services furnished by firms through which the Fund effects securities transactions may be used by First Trust in servicing all of its accounts; not all of such services may be used by First Trust in connection with the Fund. First Trust believes it is not possible to measure separately the benefits from research services to each of the accounts (including the Fund) advised by it. Because the volume and nature of the trading activities of the accounts are not uniform, the amount of commissions in excess of those charged by another broker paid by each account for brokerage and research services will vary. However, First Trust believes such costs to the Fund will not be disproportionate to the benefits received by the Fund on a continuing basis. First Trust seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell securities by the Fund and another advisory account. In some cases, this procedure could have an adverse effect on the price or the amount of securities available to the Fund. In making such allocations between the Fund and other advisory accounts, the main factors considered by First Trust are the respective investment objectives, the relative size of portfolio holding of the same or comparable securities, the availability of cash for investment and the size of investment commitments generally held.

Brokerage Commissions

Aggregate Amount of Brokerage Commissions

During the last fiscal year, First Trust Low Duration Opportunities ETF held securities of BMO Capital Markets Corp., BOFA Securities, Inc., Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, each a regular broker or dealer of the Fund as defined in Rule 10b-1 under the 1940 Act. As of October 31, 2020, the Fund’s investment in each was 0.00%, 0.01%, 0.03%, 0.59% and 0.11% of the Fund’s net assets, respectively.

Administrator, Fund Accounting Agent, Custodian, Transfer Agent, Distributor and Exchange

Custodian. The Trust has appointed BNYM to serve as the Fund’s custodian pursuant to a custody agreement (the “Custody Agreement”). Pursuant to the terms of the Custody Agreement, BNYM is generally responsible for the safekeeping of the Fund’s assets and performing various other administrative duties set forth in the agreement.

Transfer Agent. The Trust has appointed BNYM to serve as the Fund’s transfer agent and dividend disbursing agent pursuant to a transfer agency and service agreement (the “Transfer Agency Agreement”). Pursuant to the terms of the Transfer Agency Agreement, BNYM is responsible for performing and facilitating the purchases and redemptions of Creation Unit Aggregations, as well as performing other customary services of a transfer agent and dividend disbursing agent.

As compensation for the services provided by BNYM under the Administration and Accounting Agreement, Custody Agreement and Transfer Agency Agreement, the Trust, on behalf of the Fund, has agreed to pay to BNYM such compensation as may be specifically agreed upon from time to time and reimburse BNYM for out-of-pocket expenses which are a normal incident of the services provided under the agreements. Pursuant to the terms of the Unitary Fee Investment Management Agreement, the Fund does not directly pay BNYM for these services, as First Trust has assumed responsibility for the payment of these expenses out of the unitary management fee it receives from the Fund.

No fee is currently paid by the Fund under the Plan, and pursuant to a contractual agreement, the Fund will not pay 12b-1 fees any time before March 31, 2022.

The Distribution Agreement provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ written notice by the Trust to the Distributor (i) by vote of a majority of the Independent Trustees or (ii) by vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Exchange. The only relationship that the Exchange has with First Trust or the Distributor of the Fund in connection with the Fund is that the Exchange lists the shares of the Fund and disseminates the intra-day portfolio values of the Fund that are calculated by the IPV Calculator pursuant to its listing agreement with the Trust. The Exchange is not responsible for and has not participated in the determination of pricing or the timing of the issuance or sale of the shares of the Fund or in

the determination or calculation of the net asset value of the Fund. The Exchange has no obligation or liability in connection with the administration, marketing or trading of the Fund.

Additional Payments to Financial Intermediaries

sales or training programs for invited registered representatives and other intermediary employees, client and investor events and other intermediary-sponsored events, and for travel expenses, including lodging incurred by registered representatives and other employees in connection with prospecting, asset retention and due diligence trips. These payments may vary depending upon the nature of the event. First Trust and/or its affiliates make payments for such events as it deems appropriate, subject to its internal guidelines and applicable law.

Additional Information

Book Entry Only System. The following information supplements and should be read in conjunction with the Prospectus.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows.

Proxy Voting Policies and Procedures

The Trust has adopted a proxy voting policy that seeks to ensure that proxies for securities held by the Fund are voted consistently with the best interests of the Fund.

To the extent that the Fund invests in other registered investment companies (“acquired funds”), it may do so pursuant to an exemptive order granted by the SEC. The relief granted by that order is conditioned upon complying with a number of undertakings, some of which require the Fund to vote its shares in an acquired fund in the same proportion as other holders of the acquired fund’s shares. As a result, to the extent that the Fund, or another registered investment company advised by First Trust, relies on the relief granted by the exemptive order, First Trust will vote shares of an acquired fund in the same proportion as the other holders of that acquired fund’s shares.

Portfolio Schedule. The Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC’s website at www.sec.gov. The Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. A semi-annual or annual report for the Fund will become available to investors within 60 days after the period to which it relates. The Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.

Codes of Ethics. In order to mitigate the possibility that the Fund will be adversely affected by personal trading, the Trust, First Trust and the Distributor adopted Codes of Ethics under Rule 17j-1 of the 1940 Act. These Codes of Ethics contain policies restricting securities trading in personal accounts of the officers, Trustees and others who normally come into possession of information on portfolio transactions. Personnel subject to the Codes of Ethics may invest in securities that may be purchased or held by the Fund; however, the Codes of Ethics require that each transaction in such securities be reviewed by the Chief Compliance Officer or his or her designee. These Codes of Ethics are on public file with, and are available from, the SEC.

Creation and Redemption of Creation Units

Basket Composition. Rule 6c-11(c)(3) under of the 1940 Act requires an ETF relying on the exemptions offered by Rule 6c-11 to adopt and implement written policies and procedures governing the construction of baskets and the process that the ETF will use for the acceptance of baskets. In general, in connection with the construction and acceptance of baskets, the Advisor may consider various factors, including, but not limited to: (1) whether the securities, assets and other positions comprising a basket are consistent with the ETF’s investment objective(s), policies and disclosure; (2) whether the securities, assets and other positions can legally and readily be acquired, transferred and held by the ETF and/or Authorized Participant(s), as applicable; (3) whether to utilize cash, either in lieu of securities or other instruments or as a cash balancing amount; and (4) in the case of an ETF that tracks an index, whether the securities, assets and other positions aid index tracking.

after the tender of a security for redemption. This prohibition can cause operational difficulties for ETFs that hold foreign investments and exchange in-kind baskets for Creation Units. For example, local market delivery cycles for transferring foreign investments to redeeming investors, together with local market holiday schedules, can sometimes require a delivery process in excess of seven days. However, Rule 6c-11 grants relief from Section 22(e) to permit an ETF to delay satisfaction of a redemption request for more than seven days if a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming Authorized Participants, or the combination thereof prevents timely delivery of the foreign investment included in the ETF’s basket. Under this exemption, an ETF must deliver foreign investments as soon as practicable, but in no event later than 15 days after the tender to the ETF. The exemption therefore will permit a delay only to the extent that additional time for settlement is actually required, when a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming authorized participants prevents timely delivery of the foreign investment included in the ETF’s basket. If a foreign investment settles in less than 15 days, Rule 6c-11 requires an ETF to deliver it pursuant to the standard settlement time of the local market where the investment trades. Rule 6c-11 defines “foreign investment” as any security, asset or other position of the ETF issued by a foreign issuer (as defined by Rule 3b-4 under the 1934 Act), and that is traded on a trading market outside of the United States. This definition is not limited to “foreign securities,” but also includes other investments that may not be considered securities. Although these other investments may not be securities, they may present the same challenges for timely settlement as foreign securities if they are transferred in kind.

Federal Tax Matters

This section summarizes some of the main U.S. federal income tax consequences of owning shares of the Fund. This section is current as of the date of the SAI. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer or other investor with special circumstances. In addition, this section does not describe your state, local or foreign tax consequences.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, our counsel was not asked to review, and has not reached a conclusion with respect to, the federal income tax treatment of the assets to be deposited in the Fund. The following disclosure may not be sufficient for prospective investors to use for the purpose of avoiding penalties under federal tax law.

As with any investment, prospective investors should seek advice based on their individual circumstances from their own tax advisor.

The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”).

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

taking into account any capital gains or losses) for the calendar year, (2) at least 98.2% of its capital gains in excess of its capital losses (adjusted for certain ordinary losses) for the one-year period ending October 31 of the calendar year, and (3) any ordinary income and capital gains for previous years that were not distributed during those years. In order to prevent application of the excise tax, the Fund intends to make its distributions in accordance with the calendar year distribution requirement. A distribution will be treated as paid on December 31 of the current calendar year if it is declared by the Fund in October, November or December with a record date in such a month and paid by the Fund during January of the following calendar year. Such distributions will be taxable to shareholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received.

Distributions

Dividends paid out of the Fund’s investment company taxable income are generally taxable to a shareholder as ordinary income to the extent of the Fund’s earnings and profits, whether paid in cash or reinvested in additional shares. However, certain ordinary income distributions received from the Fund may be taxed at capital gains tax rates. In particular, ordinary income dividends received by an individual shareholder from a regulated investment company such as the Fund are generally taxed at the same rates that apply to net capital gain, provided that certain holding period requirements are satisfied and provided the dividends are attributable to qualifying dividends received by the Fund itself. The Fund will provide notice to its shareholders of the amount of any distributions that may be taken into account as a dividend which is eligible for the capital gains tax rates. The Fund cannot make any guarantees as to the amount of any distribution which will be regarded as a qualifying dividend.

A corporation that owns shares generally will not be entitled to the dividends received deduction with respect to many dividends received from the Fund because the dividends received deduction is generally not available for distributions from regulated investment companies. However, certain ordinary income dividends on shares that are attributable to qualifying dividends received by the Fund from certain domestic corporations may be reported by the Fund as being eligible for the dividends received deduction.

Taxes on Purchase and Redemption of Creation Units

Nature of Fund’s Investments

Futures Contracts and Options

The Fund’s transactions in futures contracts and options will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital, or short-term or long-term), may accelerate recognition of income to the Fund and may defer Fund losses. These rules could, therefore, affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark to market certain types of the positions in its portfolio (i.e., treat them as if they were closed out); and (b) may cause the Fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% distribution requirement for qualifying to be taxed as a regulated investment company and the distribution requirements for avoiding excise taxes.

Investments in Certain Foreign Corporations

Backup Withholding

Non-U.S. Shareholders

Income Not Effectively Connected. If the income from the Fund is not “effectively connected” with a U.S. trade or business carried on by the non-U.S. shareholder, distributions of investment company taxable income will generally be subject to a U.S. tax of 30% (or lower treaty rate), which tax is generally withheld from such distributions.

Distributions of capital gain dividends and any amounts retained by the Fund which are properly reported by the Fund as undistributed capital gains will not be subject to U.S. tax at the rate of 30% (or lower treaty rate) unless the non-U.S. shareholder is a nonresident alien individual and is physically present in the United States for more than 182 days during the taxable year and meets certain other requirements. However, this 30% tax on capital gains of nonresident alien individuals who are physically present in the United States for more than the 182-day period only applies in exceptional cases because any individual present in the United States for more than 182 days during the taxable year is generally treated as a resident for U.S. income tax purposes; in that case, he or she would be subject to U.S. income tax on his or her worldwide income at the graduated rates applicable to U.S. citizens, rather than the 30% U.S. tax. In the case of a non-U.S. shareholder who is a nonresident alien individual, the Fund may be required to withhold U.S. income tax from distributions of net capital gain unless the non-U.S. shareholder certifies his or her non-U.S. status under penalties of perjury or otherwise establishes an exemption. If a non-U.S. shareholder is a nonresident alien individual, any gain such shareholder realizes upon the sale or exchange of such shareholder’s shares of the Fund in the United States will ordinarily be exempt from U.S. tax unless the gain is U.S. source income and such shareholder is physically present in the United States for more than 182 days during the taxable year and meets certain other requirements. In addition, capital gain distributions attributable to gains from U.S. real property interests (including certain U.S. real property holding corporations) will generally be subject to United States withholding tax and will give rise to an obligation on the part of the non-U.S. shareholder to file a United States tax return. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. shareholders, provided that the Fund makes certain elections and certain other conditions are met.

Income Effectively Connected. If the income from the Fund is “effectively connected” with a U.S. trade or business carried on by a non-U.S. shareholder, then distributions of investment company taxable income and capital gain dividends, any amounts retained by the Fund which are properly reported by the Fund as undistributed capital gains and any gains realized upon the sale or exchange of shares of the Fund will be subject to U.S. income tax at the graduated rates applicable to U.S. citizens, residents and domestic corporations. Non-U.S. corporate shareholders may also be subject to the branch profits tax imposed by the Code. The tax consequences to a non-U.S. shareholder entitled to claim the benefits of an applicable tax treaty may differ from those described herein. Non-U.S. shareholders are advised to consult their own tax advisors with respect to the particular tax consequences to them of an investment in the Fund.

Determination of Net Asset Value

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “Net Asset Value.”

The per-share net asset value of the Fund is determined by dividing the total value of the securities and other assets, less liabilities, by the total number of shares outstanding. Under normal circumstances, daily calculation of the net asset value will utilize the last closing sale price of each security held by the Fund at the close of the market on which such security is principally listed. In determining net asset value, portfolio securities for the Fund for which accurate market quotations are readily available will be valued by the Fund accounting agent as follows:

(1)

(2)

Shares of open-end funds are valued at fair value which is based on NAV per share.

(3)

Securities traded in the OTC market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

(4)

Exchange traded options and futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, they will be fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. OTC options and futures contracts are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at their closing bid price.

(5)

Forward foreign currency contracts are fair valued at the current day’s interpolated foreign exchange rate, as calculated using the current day’s spot rate, and the 30, 60, 90 and 180-day forward rates provided by a pricing service or by certain independent dealers in such contracts.

In addition, the following types of securities will be fair valued by the Fund accounting agent as follows:

(1)

(2)

Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:

(i)

the credit conditions in the relevant market and changes thereto;

(ii)

the liquidity conditions in the relevant market and changes thereto;

(iii)

the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);

(iv)

issuer-specific conditions (such as significant credit deterioration); and

(v)

(3)

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include but are not limited to, restricted securities (securities that may not be publicly sold without registration under the 1933 Act) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of Fund net asset value (as may be the case in foreign markets on which the security is primarily traded) or is likely to make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security’s fair value. Fair value prices represent any prices not considered market value prices and are either obtained from a pricing service or are determined by the Advisor’s Pricing Committee. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from pricing services. If no market price or official close price is available from either a pricing service or no quotations are available from one or more brokers or if the Advisor’s Pricing Committee has reason to question the reliability or accuracy of a price supplied or the use of amortized cost, the value of any portfolio security held by the Fund for which reliable market prices/quotations are not readily available will be determined by the Advisor’s Pricing Committee in a manner that most appropriately reflects fair market value of the security on the valuation date, based on a consideration of all available information. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchange.

the shares of the Fund. For foreign securities, if an extraordinary market event occurs between the time the last “current” market quotation is available for a security in the Fund’s portfolio and the time the Fund’s net asset value is determined and calls into doubt whether that earlier market quotation represents fair value at the time the Fund’s net asset value is determined, the Fund accounting agent will immediately notify the Advisor’s Pricing Committee and the Advisor’s Pricing Committee shall determine the fair valuation. For foreign securities, the Advisor’s Pricing Committee may seek to determine the “fair value” of such securities by retaining a pricing service to determine the value of the securities.

Exhibit B—Credit Rating Definitions

Standard & Poor’s

LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based, in varying degrees, on the following considerations:

Likelihood of payment: capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

Nature of and provisions of the obligation and the promise S&P imputes;

AAA	An obligation rated “AAA” has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.
AA	An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.
A	An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.
BBB	An obligation rated “BBB” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB	An obligation rated “BB” is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	An obligation rated “B” is more vulnerable to nonpayment than obligations rated “BB,” but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	An obligation rated “CCC” is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.
CC	An obligation rated “CC” is currently highly vulnerable to nonpayment. The “CC” rating is used when a default has not yet occurred but S&P expects default to be a virtual certainty regardless of the anticipated time to default.
