Summary Information

Investment Objective

The First Trust Core Investment Grade ETF (the "Fund") seeks to maximize long-term total return.

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold and sell shares of the Fund. Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Shareholder Fees
(fees paid directly from your investment)

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)

None

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Management Fees	___%
Distribution and Service (12b-1) Fees	___%
Other Expenses(1)	___%
Total Annual Fund Operating Expenses	___%

(1)

“Other Expenses” is an estimate based on the expenses the Fund expects to incur for 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.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or sell all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$___	$___

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. The Fund has no operational history and therefore no historical turnover rate.

Principal Investment Strategies

Under normal market conditions, the Fund seeks to invest 100% of its Investment Portfolio in investment grade securities. Investment grade securities are those securities that are, at the time of purchase, rated as investment grade (i.e., rated Baa3/BBB- or above) by at least one nationally recognized statistical rating organization (“NRSRO”) rating such securities, or if unrated, debt securities determined by the Fund’s investment advisor to be of comparable quality. The Fund’s Investment Portfolio includes only investment grade securities purchased by the Fund’s portfolio managers (the “Investment Portfolio”) and does not include uninvested cash or any other Fund asset unconnected to the Fund’s intended portfolio, including, but not limited to, accounts receivable or assets received as part of an issuer workout. The Fund’s Investment Portfolio may also include derivatives that utilize investment grade securities as the reference asset or derivatives which the Fund's investment advisor determines to be of comparable quality, money market funds or exchange-traded funds ("ETFs") that invest substantially all of their assets in investment grade securities. In the case of a split rating on a security between one or more of the NRSROs, the Fund will consider the highest rating. 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 an NRSRO.

The Fund’s Investment Portfolio is composed of securities issued by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities; Treasury Inflation Protected Securities (“TIPS”); residential and commercial mortgage-backed securities; asset-backed securities; U.S. corporate bonds; fixed income securities issued by non-U.S. corporations and governments, including issuers with significant ties to emerging market countries; municipal bonds; and collateralized loan obligations ("CLOs").

The investment advisor seeks to maximize long-term total return by investing in a portfolio of investment grade securities. The investment advisor employs a relative value approach that opportunistically allocates the Fund’s investments across the investment grade fixed income sub-sectors. At the core of its investment process, the investment advisor utilizes quantitative and qualitative methods to assess macroeconomic and sector specific risks and opportunities. The investment advisor seeks to deliver superior risk-adjusted returns by utilizing an active and value-oriented approach to duration, yield curve, sector and security specific risk allocations.

Under normal market conditions, the Fund seeks to construct a portfolio that has a weighted average duration of +/- two years of the weighted average duration of the Bloomberg Barclays Aggregate Bond Index. 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 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 investment advisor will utilize third-party models.

The Fund may utilize exchange-traded futures contracts and options contracts, and well as over-the-counter traded derivatives including forwards, options and swaps. The Fund's use of derivatives will be used to: manage risks, serve as a substitute for a position in an underlying asset, reduce transaction costs, maintain full market exposure to manage cash flows and/or to preserve capital. 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. The Fund may also invest in cash or cash equivalents.

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.

ALTERNATIVE MINIMUM TAX RISK. Although the interest received from municipal securities is generally exempt from federal income tax, the Fund may invest in municipal securities subject to the federal alternative minimum tax. Accordingly, investment in the Fund could cause shareholders to be subject to the federal alternative minimum tax.

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 (the difference between the market price of the Fund's shares and the Fund's net asset value) and possibly face delisting and the bid/ask

spread (the difference between the price that someone is willing to pay for shares of the Fund at a specific point in time versus the price at which someone is willing to sell) on the Fund’s shares may widen.

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.

CLO RISK. CLOs bear many of the same risks as other forms of asset-backed securities, including credit risk, interest rate risk, liquidity risk and valuation risk. As they are backed by pools of loans, CLOs also bear similar risks to investing in loans directly. CLOs issue classes or “tranches” that vary in risk, expected maturity, priority of payment and yield. CLOs may experience substantial losses attributable to loan defaults. Losses caused by defaults on underlying loans are typically borne first by the holders of subordinate tranches. Investment in CLOs may decrease in market value when the CLO experiences loan defaults or credit impairment, the disappearance of one or more subordinate classes, or market anticipation of defaults and investor aversion to CLO securities as a class.

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.

CREDIT RATING AGENCY RISK. Credit ratings are determined by credit rating agencies such as S&P Global Ratings, 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.

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates and expect to continue to do so, and the Federal Reserve has announced that it intends to reverse previously implemented quantitative easing. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, in February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues

to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. The COVID-19 global pandemic, or any future public health crisis, and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. While vaccines have been developed, there is no guarantee that vaccines will be effective against emerging future variants of the disease. As this global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

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. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but 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.

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.

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.

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. 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.

ETF RISK. The Fund may invest in ETFs. 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.

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.

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.

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.

INFLATION-INDEXED SECURITIES RISK. Inflation-indexed debt securities, such as TIPS, are subject to the same risks as other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. Although the holders of TIPS receive no less than the par value of the security at maturity, if the Fund purchases TIPS in the secondary market whose principal values have previously been adjusted upward and there is a period of subsequent declining inflation rates, the Fund may receive at maturity less than it invested and incur a loss.

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 during periods of low interest rates. 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.

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.

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 objectives.

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 investment, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors 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, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares, the liquidity of an investment, and may 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, the bid/ask spread on the Fund’s shares may widen and the returns on investment may fluctuate.

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 and extension risk, given that mortgage loans generally allow borrowers to refinance. In periods of declining interest rates, borrowers may be more apt to prepay their mortgage sooner than expected. This can reduce the returns to the security holder as the amount of interest related to the price may be reduced while the proceeds may have to be reinvested at lower prevailing interest rates. This is prepayment risk. In periods of rising interest rates, borrowers may be less likely to refinance than expected thus extending the cash flows of the security such that there is increased downward price sensitivity to interest rate changes. This is extension risk. As 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. Along with prepayment risk, mortgage-related securities are significantly affected by interest rate risk.

MUNICIPAL SECURITIES RISK. Issuers, including governmental issuers, may be unable to pay their obligations as they come 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 obligation to receive the cash flows generated by the revenue source. The values of municipal securities held by the Fund 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. 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. Due to the COVID-19 pandemic, the risks of the municipal securities market have been magnified. The costs associated with combating the pandemic and the negative impact on tax revenues has adversely affected the financial condition of many states and political subdivisions. These risks may also adversely affect several sectors of the municipal bond market, such as airports, toll roads, hospitals and colleges, among many others. The full impact of the COVID-19 pandemic on state and political subdivisions’ ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund.

NEW FUND RISK. The Fund is new and has no performance history or assets as of the date of this prospectus. The Fund expects to have fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure, and in turn, the Fund’s returns for limited periods of time.

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-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.

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.

or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Fund's investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

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.

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 and the bid/ask spread on the Fund’s shares may widen.

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 significant 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.

SOVEREIGN DEBT SECURITIES RISK. Sovereign debt securities that 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.

SWAP AGREEMENTS RISK. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

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.

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.

VALUATION RISK. The sale price the Fund could receive for a security may differ from the Fund’s valuation of the security, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. 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 in valuation of debt securities than for other types of securities. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Advisor were to change its valuation policies, or if the Fund were to change pricing services, or if a pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s net asset value. Additionally, pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. 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. In addition, the value of the debt securities in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. Net asset value calculation may also be impacted by operational risks arising from factors such as failures in systems and technology.

WHEN-ISSUED, TBA AND DELAYED DELIVERY TRANSACTIONS RISK. The Fund may purchase securities on a when-issued, to-be-announced ("TBA"), delayed delivery or forward commitment basis. 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 on a when-issued, TBA, delayed delivery or forward commitment basis may give rise to investment leverage and may increase the Fund’s volatility. Default by, or bankruptcy of, a counterparty to a when-issued, TBA, delayed delivery or forward commitment 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.

Performance

The Fund does not have a performance history. Once available, the Fund’s performance information, and information that gives some indication of the risks of an investment in the Fund by comparing the Fund’s performance with a broad measure of market performance, will be available on the Fund’s website at www.ftportfolios.com. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

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, bid-ask spreads and the median bid-ask spread for the Fund’s most recent fiscal year, 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, registered investment adviser, bank or other financial intermediary (collectively, “intermediaries”), 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 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 to seek to maximize long-term total return 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.

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 (plus any borrowings for investment purposes) in investment grade securities. Any Fund investments in the Fund's Investment Portfolio (as defined above) will count towards the 80% investment requirement. 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

Under normal market conditions, the Fund seeks to invest 100% of its Investment Portfolio in investment grade securities. Investment grade securities are those securities that are, at the time of purchase, rated as investment grade (i.e., rated Baa3/BBB- or above) by at least one NRSRO rating such securities, or if unrated, debt securities determined by the Fund’s investment advisor to be of comparable quality. The Fund’s Investment Portfolio includes only investment grade securities purchased by the Fund’s portfolio managers and does not include uninvested cash or any other Fund asset unconnected to the Fund’s intended portfolio, including, but not limited to, accounts receivable or assets received as part of an issuer workout. The Fund's Investment Portfolio may also include derivatives that utilize investment grade securities as the reference asset or derivatives which the Fund's investment advisor determines to be of comparable quality, money market funds or ETFs that invest substantially all of their assets in investment grade securities. In the case of a split rating on a security between one or more of the NRSROs, the Fund will consider the highest rating. 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 an NRSRO.

The Fund’s Investment Portfolio is composed of securities issued by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities; TIPs; residential and commercial mortgage-backed securities; asset-backed securities; U.S. corporate bonds; fixed income securities issued by non-U.S. corporations and governments, including issuers with significant ties to emerging market countries; municipal bonds; and CLOs.

The investment advisor seeks to maximize long-term total return by investing in a portfolio of investment grade securities. The investment advisor employs a relative value approach that opportunistically allocates the Fund’s investments across the investment grade fixed income sub-sectors. At the core of its investment process, the investment advisor utilizes quantitative and qualitative methods to assess macroeconomic and sector specific risks and opportunities. The investment advisor seeks to deliver superior risk-adjusted returns by utilizing an active and value oriented approach to duration, yield curve, sector and security specific risk allocations.

Under normal market conditions, the Fund seeks to construct a portfolio that has a weighted average duration of +/- 2 years of the weighted average duration of the Bloomberg Barclays Aggregate Bond Index. 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 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 investment advisor will utilize third-party models.

a position in an underlying asset, reduce transaction costs, maintain full market exposure to manage cash flows and/or to preserve capital. 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. The Fund may also invest in cash or cash equivalents.

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.

Cash Equivalents and 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 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 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.

Collateralized Loan Obligations

A CLO is a financing company (generally called a “Special Purpose Vehicle” or “SPV”) created to reapportion the risk and return characteristics of a pool of assets. CLOs use funds received from the issuance of debt and equity to acquire a diverse portfolio of loans that are actively managed by the CLO manager. The debt issued by CLOs is divided into separate tranches, each of which has a different risk/return profile based on its priority of claim on the cash flows produced by the underlying loan pool. The most senior and highest rated tranche has the lowest yield but is the most loss remote as it has the highest claim on cash-flow distributions. Mezzanine tranches have higher yields but are more at risk of loss. The lowest tranche is the equity tranche, which does not have a coupon and represents a claim on all excess cash flows once the obligations for each debt tranche have been met. The equity tranche is also the most risky. The underlying loans purchased by CLOs are generally performing at the time of purchase but may become non-performing, distressed or defaulted. CLOs with underlying assets of non-performing, distressed or defaulted loans are not contemplated to comprise a significant portion of the Fund’s investments in CLOs.

Corporate Debt Securities

The Fund may invest in corporate debt securities. Corporate debt securities are fixed income securities issued by businesses to finance or expand their operations. Notes bonds, loans, 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.

Corporate debt securities are generally expected to provide periodic payments and the return of principal at maturity. Holders of corporate 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. The investment return of corporate 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.

Derivative Instruments

The Fund may utilize exchange-traded futures contracts and options contracts, as well as over-the-counter traded derivatives including forwards, options and swaps. The Fund's use of derivatives will be used to: enhance return, hedge risks, serve as a substitute for a position in an underlying asset, reduce transaction costs, maintain full market exposure to manage cash flows and/or to preserve capital.

To the extent the Fund enters into derivatives transactions, it will do so pursuant to Rule 18f-4 under the 1940 Act. Rule 18f-4 requires the Fund to implement certain policies and procedures designed to manage its derivatives risks, dependent upon the Fund’s level of exposure to derivative instruments.

ETFs

The Fund may invest in ETFs, which are registered investment companies that trade on a securities exchange. The shares of ETFs may, at times, trade at a premium or discount to their net asset value. The Fund will incur brokerage costs when purchasing and selling shares of ETFs. As a shareholder in an ETF, the Fund will bear its ratable share of the ETF’s expenses, and would remain subject to payment of the ETF’s advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses. Securities of ETFs 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.

Generally, investments in ETFs are subject to statutory limitations prescribed by the 1940 Act. These limitations include a prohibition on the Fund acquiring more than 3% of the voting shares of any other investment company, and a prohibition on the Fund investing more than 5% of its total assets in the securities of any one investment company or more than 10% of its total assets, in the aggregate, in investment company securities.

Mortgage-Related Securities

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 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 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 issued by Ginnie Mae, Fannie Mae and Freddie Mac, and their income streams.

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. government, 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.

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 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.

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-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.

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. 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.

Sovereign Debt Securities

The Fund may invest in Sovereign Debt, which includes bonds, notes and bills, issued or guaranteed by: (i) foreign governments (which may be local foreign governments); (ii) instrumentalities, agencies or other political subdivisions of foreign governments (which may be local foreign governments); (iii) central banks, sovereign entities, supranational issuers or development agencies; or (iv) entities or enterprises organized, owned, backed or sponsored by any of the entities set forth above.

Non-Principal Investments

Illiquid Investments

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 investments may include, but are not limited to certain restricted securities (securities the disposition of which is restricted under the federal securities laws), certain investments 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

ALTERNATIVE MINIMUM TAX RISK. Although the interest received from municipal securities is generally exempt from federal income tax, the Fund may invest in municipal securites subject to the federal alternative minimum taxon individuals. Therefore, all or a portion of the Fund’s otherwise exempt interest, may be taxable to shareholders subject to (or result in an increased liability under) the federal alternative minimum taxon individuals. For tax years beginning after December 31, 2022, exempt-interest dividends may affect the corporate alternative minimum tax for certain corporations.

ASSET-BACKED SECURITIES RISK. The Fund 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 and the bid/ask spread on the Fund’s shares may widen.

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 entirely 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.

CLO RISK. CLOs bear many of the same risks as other forms of asset-backed securities, including credit risk, interest rate risk, liquidity risk and valuation risk. As they are backed by pools of loans, CLOs also bear similar risks to investing in loans directly. CLOs issue classes or “tranches” that vary in risk, expected maturity, priority or payment and yield. CLOs may experience substantial losses attributable to loan defaults. Losses caused by defaults on underlying loans are typically borne first by the holders of subordinate tranches. Investment in CLOs may decrease in market value when the CLO experiences loan defaults or credit impairment, the disappearance of one or more subordinate tranches, or market anticipation of defaults and investor aversion to CLO securities as a class. The complex structure of a CLO may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results.

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.

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.

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions.

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates and expect to continue to do so, and the Federal Reserve has announced that it intends to reverse previously implemented quantitative easing. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund. While it is hard to predict whether any of these regulations will be adopted, due to the current scope of proposed regulations, any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Regulatory changes may also increase Fund operational costs, which could impact overall

performance. Certain market factors may result in central banks changing their approach in the future. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity.

The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, such as presidential, congressional and gubernatorial elections in the U.S., global elections and governmental changes and the U.S. government’s failure to agree on a long-term budget and deficit reduction plan, have and may continue to have an adverse impact on the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The potential result of a U.S. federal government shutdown may also significantly impact investor and consumer behavior, which may adversely impact the markets and global economy. Global and domestic authorities and regulators have previously responded to serious economic disruptions with ranging fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. Any change in these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which may adversely impact the Fund’s investments and performance. Any market disruptions could also delay the Fund from making sound investment decisions in a timely manner. If the Fund concentrates its investments in a region enduring geopolitical market disruption, it may face higher risk of loss, although the increasing interconnectivity between global economies and financial markets can lead to events or conditions in one country, region or financial market adversely impacting a different country, region or financial market.

Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, in February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. The COVID-19 global pandemic, or any future public health crisis, and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. While vaccines have been developed, there is no guarantee that vaccines will be effective against emerging future variants of the disease. As this global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others.

Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. As the use of technology grows, liquidity and market movements may be affected. As artificial intelligence is used more widely, the profitability and growth of Fund holdings may be impacted, which could significantly impact the overall performance of the Fund.

These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

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.

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, a lack of liquidity, potential for market manipulation, 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, the Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain emerging market countries. 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. As such, the rights and remedies associated with emerging market investment securities may be different than those available for investments in more developed markets. For example, it may be more difficult for shareholders to bring derivative litigation or for U.S. regulators to bring enforcement actions against issuers in emerging markets.

In addition, due to the differences in regulatory, accounting, audit and financial recordkeeping standards, including financial disclosures, less information about emerging market companies is publicly available and information that is available may be unreliable or outdated. This may affect the Index Provider’s ability to compute and construct the Index and may further impede the Advisor’s ability to accurately evaluate the index data provided. This potential for error in index construction and index data could affect the overall performance of 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.

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.

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 referencesand 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.

FUTURES CONTRACTS RISK. The Fund may invest in 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 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.

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.

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.

INFLATION-INDEXED SECURITIES RISK. The Fund may invest in inflation-indexed debt securities. Inflation-indexed debt securities, such as TIPS, are subject to the same risks as other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Although the holders of TIPS receive no less than the par value of the security at maturity, if the Fund purchases TIPS in the secondary market whose principal values have previously been adjusted upward and there is a period of subsequent declining inflation rates, the Fund may receive at maturity less than it invested and incur a loss. Depending on the changes in inflation rates during the period the Fund holds an inflation-indexed security, the Fund may earn less on the security than on a conventional debt security. Generally, the value of inflation-indexed securities are affected by changes in “real” interest rates, which are stated interest rates reduced by the expected impact of inflation. Inflation-indexed securities normally will decline in price when “real” interest rates rise. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Fund’s portfolio managers. The principal amounts of inflation-indexed securities are typically only adjusted periodically, and changes in the values of the securities may only approximately reflect changes in inflation rates and may occur substantially after the changes in inflation rates in question occur.

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 during periods of low interest rates. 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.

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.

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.

MORTGAGE-RELATED SECURITIES RISK. The Fund may invest in mortgage-related securities. 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 and extension risk, given that mortgage loans generally allow borrowers to refinance. In periods of declining interest rates, borrowers may be more apt to prepay their mortgage sooner than expected. This can reduce the returns to the security holder as the amount of interest related to the price may be reduced while the proceeds may have to be reinvested at lower prevailing interest rates. This is prepayment risk. In periods of rising interest rates, borrowers may be less likely to refinance than expected

thus extending the cash flows of the security such that there is increased downward price sensitivity to interest rate changes. This is extension risk. As 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. Along with prepayment risk, mortgage-related securities are significantly affected by interest rate risk.

MUNICIPAL SECURITIES MARKET LIQUIDITY RISK. From time to time, inventories of municipal securities held by brokers and dealers may decrease, lessening their ability to make a market in these securities Any reduction in market making capacity has the potential to decrease the Fund’s ability to buy or sell municipal securities and increase price volatility and trading costs, particularly during periods of economic or market stress. In addition, federal banking regulations may cause certain dealers to reduce their inventories of municipal securities, which may further decrease the Fund’s ability to buy or sell municipal securities. As a result, the Fund may be forced to accept a lower price to sell a municipal security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. The market for unrated municipal securities may be less liquid than the market for rated municipal securities of comparable quality. Decreased liquidity may negatively affect the Fund’s ability to mitigate risk and meet redemptions. Also, less public information is typically available about unrated municipal securities or their issuer which can affect the liquidity of the market.

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 a 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 a 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 a Fund’s investments. In addition, income from municipal securities held by a 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 a Fund to be taxable and may result in a significant decline in the values of such municipal securities. Due to the COVID-19 pandemic, the risks of the municipal securities market have been magnified. The costs associated with combating the pandemic and the negative impact on tax revenues has adversely affected the financial condition of many states and political subdivisions. These risks may also adversely affect several sectors of the municipal bond market, such as airports, toll roads, hospitals and colleges, among many others. The full impact of the COVID-19 pandemic on state and political subdivisions’ ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund.

NON-AGENCY SECURITIES RISK. The Funds may invest 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-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.

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.

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. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Fund’s investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

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 Fund will lose money if the value of the reference index or security rises above the strike price and the buyer exercises the option; however, such loss will be partially offset by any premium received from the sale of the option. 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 securities.

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.

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 and the bid/ask spread on the Fund’s shares may widen.

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.

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.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a significant 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.

SOVEREIGN DEBT SECURITIES RISK. The Fund may invest in ETFs that hold sovereign debt securities. 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.

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.

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.

valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Advisor were to change its valuation policies, or if the Fund were to change pricing services, or if a pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s net asset value. Additionally, pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. 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. In addition, the value of the debt securities in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. Net asset value calculation may also be impacted by operational risks arising from factors such as failures in systems and technology.

WHEN-ISSUED, TBA AND DELAYED DELIVERY TRANSACTIONS RISK. The Fund may purchase securities on a when-issued, TBA, delayed delivery or forward commitment basis. 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 on a when-issued, TBA, delayed delivery or forward commitment basis may give rise to investment leverage and may increase the Fund’s volatility. Default by, or bankruptcy of, a counterparty to a when-issued, TBA or delayed delivery 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 when-issued, TBA, delayed delivery or forward commitment transactions. Such transactions require mandatory collateralization which could increase the cost of such transactions and impose added operational complexity.

Non-Principal Risks

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 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.

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.

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."

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.

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.

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 [___]% 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.

As approved by the Trust’s Board of Trustees, the management fee paid to First Trust will be reduced at certain levels of Fund net assets (“breakpoints”). See the Fund's Statement of Additional Information for more information on the breakpoints.

A discussion regarding the Board’s approval of the Investment Management Agreement will be available in the Fund’s Annual Report to Shareholders for the fiscal period ended October 31, 2023.

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.

For purposes of the 1940 Act, the Fund is treated as a registered investment company and 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 and the related rules and interpretations.

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.

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

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.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service ("IRS") could disagree with any conclusions set forth in this section. 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

The Fund intends to qualify as a “regulated investment company” (a “RIC”) under the federal tax laws. If the Fund qualifies as a RIC and distributes its income as required by the tax law, the Fund generally will not pay federal income taxes.

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, 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.

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.

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 RICs.

Capital Gains and Losses

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. 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.

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 brokerage fees, if any. 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 IRS, 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 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. For tax years after December 31, 2022, amounts paid to or recognized by a non-U.S. affiliate that are excluded from tax under the portfolio interest, capital gain dividends, short-term capital gains or tax-exempt interest dividend exceptions or applicable treaties, may be taken into consideration in determining whether a corporation is an “applicable corporation” subject to a 15% minimum tax on adjusted financial statement income.

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.

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 ____________, 2025. 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 (“NAV”) is determined as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open for trading. If the NYSE closes early on a valuation day, the Fund’s NAV will be determined as of that time. The Fund’s NAV is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

Section 2(a)(41) of the 1940 Act provides that when a market quotation is readily available for a fund’s portfolio investment, it must be valued at the market value. Rule 2a-5 under the 1940 Act (“Rule 2a-5”) defines a readily available market quotation as “a quoted price (unadjusted) in active markets for identical investments that the fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable.” If a market quotation is not “readily available,” then the portfolio investment must be fair valued as determined in good faith by a fund’s board of trustees.

Rule 2a-5 permits a fund’s board of trustees to designate the fund’s investment adviser as its “valuation designee” to perform fair value determinations, subject to certain conditions. Accordingly, the Fund’s Board has designated First Trust as its valuation designee (the “Valuation Designee”) pursuant to Rule 2a-5 and has directed the Valuation Designee to perform the functions required in Rule 2a-5(a) subject to the requirements of Rule 2a-5(b) on behalf of all portfolio investments of the Fund, subject to the Board’s oversight. First Trust has established a pricing committee (the “Pricing Committee”) to assist in the administration of the duties of the Valuation Designee. The Valuation Designee has adopted valuation procedures for the First Trust Funds (the “Valuation Procedures”), a brief summary of which is set forth below.

The Pricing Committee has identified certain portfolio investments that are routinely categorized as having a readily available market quotation. The market value of an investment with a readily available market quotation is typically determined on the basis of official closing prices or last reported sale prices or equivalent price, although this can vary based on investment type and/or the availability of such prices.

The Pricing Committee has also identified certain portfolio investments that are routinely categorized as fair valued investments. In general, for such investments, the Fund’s accounting agent will obtain all pricing data for use in valuing such investments from a pricing service provider approved by the Pricing Committee (each, a “Pricing Service Provider”), subject to the oversight of the Pricing Committee. Pricing Service Providers typically value non-exchange-traded instruments utilizing a range of market-based inputs and assumptions. For example, when available, Pricing Service Providers may utilize inputs such as benchmark yields, reported trades, broker-dealer quotes, spreads, and transactions for comparable instruments. In pricing certain instruments, a Pricing Service Provider may consider information about an instrument’s issuer or market activity. Pricing Service Provider valuations of non-exchange-traded instruments generally represent the service’s good faith opinion as to what the holder of an instrument would receive in an orderly transaction for an institutional round lot position under current market conditions. Certain exchange-traded options, such as FLEX Options, are typically valued using a model-based price provided by a Pricing Service Provider.

Portfolio investments trading on foreign exchanges or over-the-counter markets that close prior to the close of the NYSE may be fair valued using a systematic fair valuation model provided by a Pricing Service Provider. If these foreign securities meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of certain foreign markets.

If no price is available from a Pricing Service Provider or if the Pricing Committee has reason to question the accuracy or the reliability of a price supplied for a portfolio investment or the use of amortized cost, the Pricing Committee will determine the fair value of such portfolio investment in a manner that it believes most appropriately reflects the fair value of the portfolio

investment on the valuation date (a “Special Fair Value Pricing Situation”). In a Special Fair Value Pricing Situation, the Pricing Committee will determine a fair value price subject to the process outlined in the Valuation Procedures and based on a consideration of all available information to the Pricing Committee at the time of the determination.

Additionally, 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 NAV is determined that calls into doubt whether that earlier market quotation represents fair value at the time the Fund’s NAV is determined, the Pricing Committee will determine the fair valuation as set forth in the Valuation Procedures.

Fair value represents a good faith approximation of the value of a portfolio investment and is the amount the Fund might reasonably expect to receive from the current sale of that investment in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations, if any, and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. While the Valuation Procedures and Valuation Designee’s processes are intended to result in the Fund’s NAV calculation that fairly reflects the values as of the time of pricing, the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

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 Provider. All assets denominated in foreign currencies will be converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Fund Service Providers

The Bank of New York Mellon, 240 Greenwich Street, New York, New York 10286, acts as the administrator, custodian and fund accounting and transfer agent for the Fund. Chapman and Cutler LLP, 320 S. Canal St., Chicago, Illinois 60606, serves as legal counsel to the Fund.

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.

Financial Highlights

The Fund is new and has no performance history as of the date of this prospectus. Financial information therefore is not available.

Other Information

Continuous Offering

The Fund will issue, on a continuous offering basis, its shares in one or more groups of a fixed number of Fund shares (each such group of such specified number of individual Fund shares, a “Creation Unit Aggregation”). The method by which Creation Unit Aggregations of Fund shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Unit Aggregations of shares are issued and sold by the Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act, may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Unit Aggregations after placing an order with FTP, breaks them down into constituent shares and sells such shares directly to customers, or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not underwriters but are participating in a distribution (as contrasted with ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(a)(3)(C) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. Firms that incur a prospectus delivery obligation with respect to shares are reminded that, under the Securities Act Rule 153, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to a broker-dealer in connection with a sale on the Exchange is satisfied by the fact that the prospectus is available from the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available with respect to transactions on a national securities exchange, a trading facility or an alternative trading system.

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 [__] series. This SAI relates to the Fund, which is a non-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 objective 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 shares 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 Trustees 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 may, except in limited circumstances, be amended by the Trustees in any respect without a shareholder vote. The Declaration provides that the Trustees may establish the number of Trustees and that vacancies on the Board of Trustees may be filled by the remaining Trustees, except when election of Trustees by the shareholders is required under the 1940 Act. Trustees are then elected by a plurality of votes cast by shareholders at a meeting at which a quorum is present. 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 provides that a Trustee acting in his or her capacity as Trustee is liable to the Trust for his or her own bad faith,willful misfeasance, gross negligence, or reckless disregard of his or her duties involved in the conduct of the individual’s office, and for nothing else and shall not be liable for errors of judgment or mistakes of fact or law. The Declaration also provides that the Trustees of the Trust will be subject to the laws of the Commonwealth of Massachusetts relating to Massachusetts business trusts, but not to the laws of Massachusetts relating to the trustees of common law trusts, such as donative or probate type trusts. 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.

These provisions are not intended to restrict any shareholder rights under the federal securities laws and the Declaration specifically provides that no provision of the Declaration shall be effective to require a waiver of compliance with any provision of, or 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 of any valid rule, regulation, or order of the 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 NYSE Arca, Inc. ("NYSE Arca" 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) 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.

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 as permitted under the 1940 Act.

(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 will 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, its agencies or instrumentalities, or securities of other investment companies.

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 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 borrowing shall be at least 300%. 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.

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).

Notwithstanding restriction (7) above, to the extent the Fund invests in other investment companies, it will consider, to the extent practicable, the investments of the underlying investment companies when determining compliance with the limitations set forth in restriction (7) above.

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.

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.

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 (plus any borrowings for investment purposes) in investment grade securities. As a result, the Fund must provide shareholders with a notice meeting the requirements of Rule 35d-1(c) at least 60 days prior to any change of the Fund’s Name Policy.

Investment Strategies

The following information supplements the discussion of the Fund’s investment objective, policies and strategies that appears in the Prospectus.

Under normal market conditions, the Fund seeks to invest 100% of its Investment Portfolio (as defined in the prospectus) in investment grade securities. The Fund’s Investment Portfolio is composed of securities issued by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities; Treasury Inflation Protected Securities (“TIPS”); residential and commercial mortgage-backed securities; asset-backed securities; U.S. corporate bonds; fixed income securities issued by non-U.S. corporations and governments, including issuers with significant ties to emerging market countries; municipal bonds; and collateralized loan obligations ("CLOs"). For purposes of compliance with this investment test, the Fund may also invest in derivatives that utilize investment grade securities as the reference asset or derivatives which the Fund's investment advisor determines to be of comparable quality, money market funds or exchange-traded funds ("ETFs") that invest substantially all of their assets in investment grade securities.

Types of 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 due on a regular basis. Those payments, if collected, are distributed to bond holders according to that securitization’s indenture. The average life of asset-backed securities varies with the maturities of the underlying instruments

and, as a result of prepayments and time-tranching of cash flows, can often be less than the original maturity of the assets underlying the securities.

Collateralized Loan Obligations (“CLOs”). A CLO is a financing company (generally called a Special Purpose Vehicle or “SPV”) created to reapportion the risk and return characteristics of a pool of assets. While the assets underlying CLOs are typically Senior Loans, the assets may also include (i) unsecured loans, (ii) other debt securities that are rated below investment grade, (iii) debt tranches of other CLOs and (iv) equity securities incidental to investments in Senior Loans. When investing in CLOs, the Fund will not invest in equity tranches, which are the lowest tranche. The underlying Senior Loans purchased by CLOs are generally performing at the time of purchase but may become non-performing, distressed or defaulted. CLOs with underlying assets of non-performing, distressed or defaulted loans are not contemplated to comprise a significant portion of the Fund’s investments in CLOs. The key feature of the CLO structure is the prioritization of the cash flows from a pool of debt securities among the several classes of the CLO. The SPV is a company founded solely for the purpose of securitizing payment claims arising out of this diversified asset pool. On this basis, marketable securities are issued by the SPV which, due to the diversification of the underlying risk, generally represent a lower level of risk than the original assets. The redemption of the securities issued by the SPV typically takes place at maturity out of the cash flow generated by the collected claims.

Holders of CLOs bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk.

The Fund may have the right to receive payments only from the CLOs, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain CLOs enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in CLOs generally pay their share of the CLO’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying a CLO will rise or fall, these prices and, therefore, the prices of CLOs will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a CLO uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the CLOs owned by the Fund.

Certain CLOs may be thinly traded or have a limited trading market. CLOs are typically privately offered and sold. As a result, investments in CLOs may be characterized by the Fund as illiquid securities. In addition to the general risks associated with debt securities discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Corporate Bonds. Corporate bonds, also known as fixed-income securities, are debt obligations issued by corporations. Corporate bonds are generally used by corporations to borrow money from investors. Corporate bonds may be either secured or unsecured. Collateral used for secured debt includes, but is not limited to, real property, machinery, equipment, accounts receivable, stocks, bonds or notes. If a corporate bond is unsecured, it is known as a debenture. Holders of corporate bonds, as creditors, have a prior legal claim over common and preferred stockholders 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 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.

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.

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.

Derivatives. The Fund may utilize exchange-traded futures contracts and options contracts, and well as over-the-counter traded derivatives including forwards, options and swaps. The Fund's use of derivatives will be used to: enhance return, hedge risks, serve as a substitute for a position in an underlying asset, reduce transaction costs, maintain full market exposure to manage cash flows and/or to preserve capital.

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.

Fixed Income Investments and Cash Equivalents. Normally, the Fund invests substantially all of its assets to meet its investment objectives; 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.

Fixed income investments and cash equivalents 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 U.S. 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 the 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; 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 investments and be subject to the Fund's 15% restriction on investments in illiquid investments. 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, 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)

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)

The Fund may invest in shares of money market funds, as consistent with its investment objective 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.

Illiquid Investments. The Fund may invest in illiquid investments (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 investments 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 investments if, as a result, such investments 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 investments 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 investments 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 investments or the depreciation of liquid investments, the Fund should be in a position where more than 15% of the value of its net assets are invested in illiquid investments, 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. The Fund may invest in securities of other investment companies, including 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 their 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. 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 may invest in mortgage-based securities. 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, 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 Fund may invest in mortgage-backed securities that are 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.

Municipal Securities. The Fund may invest in municipal securities. Municipal securities are debt securities that generally 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.

Non-U.S. Investments. The Fund may invest in non-U.S. securities. 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 supra-national 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.

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

The Fund may engage in hedging activities and, in this regard, may utilize forward contracts, currency spot transactions and futures contracts.

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 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 Derivative Transactions

The Fund limits its direct investments in derivative instruments to the extent necessary for the Advisor 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 certain derivative instruments (excluding activity for “bona fide hedging purposes,” as defined by the CFTC) such that each 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 the Fund’s 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.

The Advisor 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.

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. 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

In order to generate additional income, as a non-principal investment strategy, First Trust is authorized to select certain 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.

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 in an amount at least equal to the value of the borrowed securities, marked to market daily. 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.

Additional Market Disruption Risk

In February 2022, Russia commenced a military attack on Ukraine. In response, various countries, including the United States, issued broad-ranging sanctions on Russia and certain Russian companies and individuals. The hostilities between the two countries may escalate and any existing or future sanctions could have a severe adverse effect on Russia’s economy, currency, companies and region as well as negatively impact other regional and global economic markets of the world (including Europe and the United States), companies in such countries and various sectors, industries and markets for securities and commodities globally, such as oil and natural gas. Accordingly, the hostilities and sanctions may have a negative effect on the Fund’s investments and performance beyond any direct exposure to Russian issuers or those of adjoining geographic regions. Russia may also take retaliatory actions or countermeasures, such as cyberattacks and espionage, which may negatively impact the countries and companies in which the Fund may invest. The extent and duration of the military action or future escalation of such hostilities; the extent and impact of existing and any future sanctions, market disruptions and volatility; and the result of any diplomatic negotiations cannot be predicted. These and any related events could have a significant negative impact on certain of the Fund’s investments as well as the Fund’s performance, and the value or liquidity of certain securities held by the Fund may decline significantly.

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.

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.

Debt Securities Risk

In addition to the risks described elsewhere in the Prospectus and this SAI, debt securities are subject to certain other risks, including:

•

Issuer Risk. The value of debt securities may decline for a number of reasons which directly relate to the issuer, such as management performance, leverage and reduced demand for the issuer’s goods and services. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer.

•

Interest Rate Risk. Interest rate risk is the risk that debt securities will decline in value because of changes in market interest rates. When market interest rates rise, the market value of fixed rate securities generally will fall. Currently, interest rates are at or near historical lows and, as a result, they are likely to rise over time. Market value generally falls further for fixed rate securities with longer duration. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected prepayments. This may lock in a below-market yield, increase the security’s duration and further reduce the value of the security. Investments in debt securities with long-term maturities may experience significant price declines if long-term interest rates increase. Fluctuations in the value of portfolio securities will not affect interest income on existing portfolio securities but will be reflected in the Fund’s net asset value. Since the magnitude of these fluctuations will generally be greater at times when the Fund’s average maturity is longer, under certain market conditions the Fund may, for temporary defensive purposes, accept lower current income from short-term investments rather than investing in higher yielding long-term securities.

•

Liquidity Risk. Certain debt securities may be substantially less liquid than many other securities, such as common stocks traded on an exchange. Illiquid investments involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximating the value at which the Fund is carrying the securities on its books.

•

Prepayment Risk. During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest the proceeds from such prepayment in lower yielding securities, which may result in a decline in the Fund’s income and distributions to common shareholders of the Fund. This is known as call or prepayment risk. Debt securities frequently have call features that allow the issuer to redeem the security prior to its stated maturity. An issuer may redeem an obligation if the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. If the Fund bought a security at a premium, the premium could be lost in the event of a prepayment.

•

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the Fund portfolio’s current earnings rate. A decline in income could affect the market price of the Fund’s common shares or the overall return of the Fund.

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. Certain specific risks associated with an investment in derivatives may include: market risk, credit risk, correlation risk, liquidity 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 objective, 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 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 over-the-counter (“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 the Fund. Such counterparty risk is accentuated in the case of contracts with longer maturities where there is a greater risk that a specific event may prevent or delay settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties. The Fund is not restricted from dealing with any particular counterparty or from concentrating any or all of its transactions with one counterparty. 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. In addition, the Fund’s success in using hedging instruments is subject to the ability of the portfolio manager to correctly predict changes in relationships of such hedge instruments to the Fund’s portfolio holdings, and there can be no assurance that the judgment of the portfolio manager in this respect will be accurate. An imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to a risk of loss.

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 to maintain segregated accounts and/or make margin payments when taking 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)

Volatility. The prices of many derivative instruments are highly volatile. Price movements of such instruments may be influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments, and national and international political and economic events and policies. The value of such instruments also may depend upon the price of the securities or currencies underlying them.

(7)

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.

Liquidity Risk

Although the Fund limits its investments in illiquid investments 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 the 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 the securities will be maintained or that there will be sufficient liquidity of the securities in any markets made. The price at which the 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, natural disasters 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 and the bid/ask spread on the Fund’s shares may widen.

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 ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. While vaccines have been developed, there is no guarantee that vaccines will be effective against future variants of the disease. The impact of the 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.

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 obligation 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 securities 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. There are various different types of municipal securities, each with its own unique risk profile. Some of these risks include:

•

General Obligation Bonds Risk—timely payments depend on the issuer’s credit quality, ability to raise tax revenues and ability to maintain an adequate tax base;

•

Revenue Bonds Risk—timely payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source, and may be negatively impacted by the general credit of the user of the facility;

•

Private Activity Bonds Risk—municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise, which is solely responsible for paying the principal and interest on the bonds, and payment under these bonds depends on the private enterprise’s ability to do so;

•

Moral Obligation Bonds Risk—moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality;

•

Municipal Notes Risk—municipal notes are shorter-term municipal debt obligations that pay interest that is, in the opinion of bond counsel for the issuer at the time of issuance, generally excludable from gross income for federal income tax purposes (except that the interest may be includable in taxable income for purposes of the federal alternative minimum taxon individuals) and that have a maturity that is generally one year or less.For tax years beginning after December 31, 2022, interest on the bonds may affect the corporate alternative minimum tax for certain corporations. If there is a shortfall in the anticipated proceeds, the notes may not be fully repaid and the Fund may lose money; and

•

Municipal Lease Obligations Risk—in a municipal lease obligation, the issuer agrees to make payments when due on the lease obligation. Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property.

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. 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.

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.

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 six Trustees of the Trust, one of whom is an “interested person” (as the term is defined in the 1940 Act) and five 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. Unless otherwise indicated, the address of all persons below is c/o First Trust Advisors L.P., 120 East Liberty Drive, Suite 400, Wheaton, IL 60187.

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 ten 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 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 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 [___] portfolios advised by First Trust (each a “First Trust Fund” and collectively, the “First Trust Fund Complex”). None of the Independent Trustees 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 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 five 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 six 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.

The Board has established five standing committees (as described below) and has delegated certain of its responsibilities to those committees. The Board and its committees meet frequently throughout the year to oversee the Fund's activities, review contractual arrangements with and performance of service providers, oversee compliance with regulatory requirements and review Fund performance. The Independent Trustees are represented by independent legal counsel at all Board and committee meetings (other than meetings of the 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 Chairs and the Lead Independent Trustee rotate every three years in serving as Chair 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 Mr. Keith are members of the Executive Committee.

The Nominating and Governance Committee is responsible for appointing and nominating non-interested persons to the Board of Trustees. Messrs. Erickson, Kadlec, Keith, Nielson and Ms. Keefe 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 Chair of the Nominating and Governance Committee and to counsel to the Independent Trustees.

The Valuation Committee is responsible for the oversight of the Advisor as the “Valuation Designee” under Rule 2a-5 of the 1940 Act and its implementation of the valuation of the securities held in the Fund's portfolio. Messrs. Erickson, Kadlec, Keith, Nielson and Ms. Keefe are members of the Valuation Committee.

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, Nielson and Ms. Keefe serve on the Audit Committee.

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, Keith and Nielson serve on the Dividend Committee.

Executive Officers

The executive officers of the Trust hold the same positions with each fund in the First Trust Fund Complex (representing [___] portfolios) as they hold with the Trust, except Messrs. Russo and Ueland who are executive officers 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 and the Fund's independent auditors, 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 oversees the Advisor's performance as Valuation Designee.

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, 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.

Richard E. Erickson, M.D., is an orthopedic surgeon with Edward-Elmhurst Medical Group. He was previously President of Wheaton Orthopedics, a co-owner and director of a fitness center and a limited partner of two real estate companies. Dr. Erickson has served as a Trustee of each First Trust Fund since its inception and of the First Trust Funds since 1999. Dr. Erickson has also served as the Lead Independent Trustee (2008–2009 and 2017–2019) and on the Executive Committee (2008–2009 and 2017–2022), Chairman of the Nominating and Governance Committee (2003–2007 and 2014–2016), Chairman of the Audit Committee (2012–2013) and Chairman of the Valuation Committee (June 2006–2007; 2010–2011 and 2020–2022) of the First Trust Funds. He currently serves as Chairman of the Audit Committee (since January 1, 2023) of the First Trust Funds.

Thomas R. Kadlec was previously President of ADM Investor Services Inc. (“ADMIS”), a futures commission merchant and wholly-owned subsidiary of the Archer Daniels Midland Company (“ADM”) from 2010 to July 2022. Mr. Kadlec was employed by ADMIS and its affiliates since 1990 in various accounting, financial, operations and risk management capacities. Mr. Kadlec served on the boards of several international affiliates of ADMIS until July 2022 and served as a member of ADM’s Integrated Risk Committee from 2008–2018, which was tasked with the duty of implementing and communicating enterprise-wide risk management. From 2014 to 2022, Mr. Kadlec was on the board of the Futures Industry Association. In 2017, Mr. Kadlec was elected to the board of the National Futures Association.

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 Fund.

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.

First Trust acts as investment advisor for the Fund and manages the investment and reinvestment of the assets of the Fund. First Trust also administers the Trust’s business affairs, provides office facilities and equipment and certain clerical, bookkeeping 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 [____]% 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.

As approved by the Trust’s Board of Trustees, the management fee paid to the Advisor will be reduced at certain levels of Fund net assets (“breakpoints”) and calculated pursuant to the schedule below:

Management Fee	Breakpoints
[________]%	Fund net assets up to and including $2.5 billion
[________]%	Fund net assets greater than $2.5 billion up to and including $5 billion
[________]%	Fund net assets greater than $5 billion up to and including $7.5 billion
[________]%	Fund net assets greater than $7.5 billion up to and including $10 billion
[________]%	Fund net assets greater than $10 billion

Name	Position with First Trust	Length of Service with First Trust	Principal Occupation During Past Five Years

Jim Snyder: Mr. Snyder serves as a Senior Portfolio Manager for the First Trust Securitized Products Group.

Jeremiah Charles: Mr. Charles serves as a Senior Portfolio Manager for the First Trust Securitized Products Group.

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.

Owen Aronson: Mr. Aronson is a Vice President and Portfolio Manager for First Trust.

Nathan Simons, CFA: Mr. Simons serves as Vice President and Portfolio Manager for First Trust.

Scott Skowronski, CFA: Mr. Skowronski serves as Senior Vice President and Portfolio Manager for First Trust.

As of ____, 2023, none of the portfolio managers beneficially owned 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 December 31, 2022, 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)
Jim Snyder	__ ($_____________)	__ ($____)	__ ($_____________)
Jeremiah Charles	__ ($_____________)	__ ($____)	__ ($_____________)
Todd Larson, CFA	__ ($_____________)	__ ($____)	__ ($_____________)
Owen Aronson	__ ($_____________)	__ ($____)	__ ($_____________)
Nathan Simons, CFA	__ ($_____________)	__ ($____)	__ ($_____________)
Scott Skowronski, CFA	__ ($_____________)	__ ($____)	__ ($_____________)

Conflicts. None of the accounts managed by the portfolio managers pay 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.

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.

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.

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 Investment Management Agreement,

the 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.

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 "Creations and Redemption of Creation Unit Aggregations."

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 such 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 ____________, 2025.

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 Depositary 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 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

First Trust or its affiliates may from time to time make payments, out of their own resources, to certain broker-dealers, registered investment advisers, banks or other intermediaries (collectively, “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; (v) provide payments to broker-dealers to help defray their technology or infrastructure costs; and (vi) make payments for expenses associated with intermediaries’ use of First Trust Funds including, but not limited to, the use of First Trust Funds in model portfolios.

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 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.

Payments to intermediaries, in certain circumstances, may also be made in connection with the distribution of model portfolios developed by First Trust, such as the inclusion of such model portfolios on an intermediary’s platform, as well as in connection with the marketing and sale of, and/or product training regarding such model portfolios, or servicing of accounts tracking such model portfolios. Such payments may be variable or fixed fee payments for platform support, or other payments in the form of a variable or fixed fee or a per position fee, or may relate to the amount of assets an intermediary’s clients have invested in the First Trust Funds in such models developed by First Trust, the management fee, the total expense ratio, or sales of the First Trust Funds in such models developed by First Trust. Some intermediaries also provide related data regarding transactions in specific model portfolios, First Trust Funds and investment strategies to First Trust in exchange for a fee.

First Trust and/or its affiliates may enter into arrangements with third parties, such as a software provider, whereby First Trust may license certain technology or other services from such entity in exchange for licensing or other fees which may be, in whole or in part, dependent on the value of First Trust mutual funds or ETFs held through such software or other service. Such third party may also offer price concessions to broker dealers, investment advisers or other financial intermediaries that license technology or other services that may be dependent, in whole or in part, on the value of First Trust mutual funds or ETFs held through such software or other service.

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, 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.

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. The First Trust Proxy Voting Guidelines are attached hereto as Exhibit B. 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 generally vote proxies relating to such company’s securities in accordance with the ISS recommendations to avoid any conflict of interest.

First Trust has adopted the ISS Proxy Voting Guidelines. While these guidelines are not intended to be all-inclusive, they do provide guidance on First Trust’s general voting policies. First Trust’s use of the ISS Proxy Voting Guidelines is not intended to constrain First Trust’s consideration of any proxy proposal, and there are times when First Trust deviates from the ISS Proxy Voting Guidelines. This includes when required by Rule 12d1-4 under the 1940 Act or when agreed to by the Fund and certain acquired funds as permitted under Rule 12d1-4 under the 1940 Act, if applicable. Generally, First Trust will not rely on ISS Proxy Voting Guidelines to withhold votes or vote against directors solely based on quota criteria or the exclusion of certain climate-related disclosures, which may or may not relate to the company’s core business or may not materially impact shareholder value. First Trust will consider such proxy voting decisions in light of merit-based considerations which it believes may impact shareholder value. First Trust retains final authority and fiduciary responsibility for proxy voting.

Information regarding how the Fund voted proxies (if any) 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.

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.

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 CCO 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 the 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, Juneteenth, 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.”

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.

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 or reject 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, in the opinion of the Fund, be unlawful; or (v) 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 right to reject a creation order transmitted to it provided that such action does not result in a suspension of sales of creation units in contravention of 6c-11 and the SEC’s positions thereunder. 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 (“IRS”) could disagree with any conclusions set forth in this section. 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 (a “RIC”) 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 RICs, 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 RICs 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 RICs) 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.

As a RIC, the Fund generally will not be subject to U.S. federal income tax on its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid) and net capital gain (the excess of net long-term capital gain over net short-term capital loss), if any, that it distributes to shareholders. The Fund intends to distribute to its shareholders, at least annually, substantially all of its investment company taxable income 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 RIC 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 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.

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 treated as a long-term capital loss to the extent of any distributions of long-term capital gain received by the shareholder with respect to such shares.

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 IRS, 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 (i) 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 (ii) 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 RIC and the distribution requirements for avoiding excise taxes.

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 IRS 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 ordividends. 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 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. For tax years after December 31, 2022, amounts paid to or recognized by a non-U.S. affiliate that are excluded from tax under the portfolio interest, capital gain dividends, short-term capital gains or tax-exempt interest dividend exceptions or applicable treaties, may be taken into consideration in determining whether a corporation is an “applicable corporation” subject to a 15% minimum tax on adjusted financial statement income.

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.

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. 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.

Other Taxation

Fund shareholders may be subject to state, local and foreign taxes on their Fund distributions. 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 Fund’s net asset value is determined as set forth in the Prospectus in the section entitled “Net Asset Value.”

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 RIC 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.

Miscellaneous Information

Counsel. Chapman and Cutler LLP, 320 S. Canal St., Chicago, Illinois 60606, is counsel to the Trust.

Independent Registered Public Accounting Firm. Deloitte & Touche LLP, 111 South Wacker Drive, Chicago, Illinois 60606, serves as the Fund's independent registered public accounting firm. The firm audits the Fund's financial statements and performs other related audit services.

Exhibit A—Credit Rating Definitions

S&P Global RATINGS

A S&P Global Ratings 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 S&P Global Rating’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 S&P Global Ratings. 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.

A-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 the next five business days in the absence of a stated grace

period or within the earlier of the stated grace period or the next 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. A rating on an obligation is lowered to 'D' if

it is subject to a distressed debt restructuring.

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 supra-national 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

A-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.

A-3

Restricted default. ‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced an uncured payment

default on a bond, loan or other material financial obligation but which has not entered into bankruptcy

filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not

otherwise ceased operating. This would include:

•the selective payment default on a specific class or currency of debt;

•the uncured expiry of any applicable grace period, cure period or default forbearance period following a

payment default on a bank loan, capital markets security or other material financial obligation;

•the extension of multiple waivers or forbearance periods upon a payment default on one or more material

financial obligations, either in series or in parallel; or

•execution of a distressed debt exchange on one or more material financial obligations.

Default. ‘D’ ratings indicate an issuer that in Fitch’s opinion has entered into bankruptcy filings,

administration, receivership, liquidation or other formal winding-up procedure, or which has otherwise ceased

business.

Default ratings are not assigned prospectively to entities or their obligations; within this context, non-payment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

“Imminent” default typically refers to the occasion where a payment default has been intimated by the issuer, and is all but inevitable. This may, for example, be where an issuer has missed a scheduled payment, but (as is typical) has a grace period during which it may cure the payment default. Another alternative would be where an issuer has formally announced a distressed debt exchange, but the date of the exchange still lies several days or weeks in the immediate future.

In all cases, the assignment of a default rating reflects the agency’s opinion as to the most appropriate rating category consistent with the rest of its universe of ratings, and may differ from the definition of default under the terms of an issuer’s financial obligations or local commercial practice.

Exhibit B—Proxy Voting Guidelines

FIRST TRUST ADVISORS L.P.
PROXY VOTING GUIDELINES

First Trust Advisors L.P. (“FTA” or the “Adviser”) serves as investment adviser to open- and closed-end investment companies, and other collective investments (“Funds”), as well as separately managed accounts (collectively, “Clients”). As part of these services, the Adviser has, in most cases, agreed to or been delegated proxy voting responsibility on such Clients’ behalf (“Proxy Clients”). FTA is required to adopt and implement policies and procedures reasonably designed to ensure proxy voting on behalf of Proxy Clients is conducted in a manner that is in their best interests and addresses how conflicts of interest between FTA’s interests and Proxy Clients’ interests are managed. FTA has adopted the following policies and procedures to comply with this requirement (the “Policy”).

(1)

It is the Adviser’s policy to seek and to ensure that proxies are voted consistently and in the best economic interests of the Proxy Client. The FTA Investment Committee is responsible for the implementation of the Policy.

(2)

The Adviser engaged Institutional Shareholder Services (“ISS”) to provide proxy research, recommendations, and voting services. ISS provides a password protected website which is accessible to authorized FTA personnel to download upcoming proxy meeting data, including research reports, of companies held in Proxy Client portfolios. The website can be used to view proposed proxy votes and to enter votes for upcoming meetings for Proxy Client portfolio securities.

(3)

FTA will generally follow the ISS Proxy Voting Guidelines (the “Guidelines”) to vote proxies for Proxy Clients’ accounts, so long as such Guidelines are considered to be in the best interests of the Proxy Client, and there are no noted or perceived conflicts of interest. FTA’s use of the Guidelines is not intended to constrain FTA’s consideration of any proxy proposal, and there are times when FTA deviates from the Guidelines. This includes when required by Rule 12d1-4 agreements between Fund Proxy Clients and certain acquired funds, if applicable. Generally, FTA will not rely on ISS Proxy Voting Guidelines to withhold votes or vote against directors solely based on (i) quota criteria or (ii) the exclusion of certain climate-related disclosures, which may or may not relate to the company’s core business or may not materially impact shareholder value. In such cases, FTA will consider such proxy voting decisions in light of merit-based considerations which it believes may impact shareholder value. In addition, FTA will vote against shareholder proposals that are not related to a company’s core business and/or do not appear to be an appropriate use of a company’s resources to maximize shareholder value. FTA retains final authority and fiduciary responsibility for proxy voting.

In certain circumstances, where FTA has determined that it is consistent with Proxy Clients’ best interests, FTA will not vote a proxy on behalf of one or more Proxy Clients. Such circumstances include:

(a)

Limited Value. Proxies will not be required to be voted on securities in a Proxy Client’s account if the value of the Proxy Client’s economic interest in the securities is indeterminable or insignificant (less than $1,000). Proxies will also not be required to be voted for any securities that are no longer held in Proxy Client’s account(s).

(b)

Securities Lending Program. When Fund portfolio securities are out on loan, they are transferred into the borrower’s name and are voted by the borrower, in its discretion. In most cases, FTA will not recall securities on loan in order to vote a proxy. However, where FTA determines that a proxy vote, or other shareholder action, is materially important to the Fund Proxy Client’s account, FTA will make a good faith effort to recall the security for purposes of voting, understanding that in certain cases, the attempt to recall the security may not be effective in time to meet voting deadlines. In certain instances, in FTA’s discretion, disclosure regarding FTA’s process for determining whether or not to recall Fund portfolio securities on loan for proxy voting purposes may be provided as part of the Funds’ annual Form N-PX filing.

(c)

Unjustifiable Costs. In certain circumstances, based on cost-benefit analysis, FTA may choose not to vote when the cost of voting on behalf of a Proxy Client would exceed any anticipated benefits of the proxy proposal to such Proxy Client (e.g. foreign securities).

(d)

International Markets Share Blocking. Share blocking is the “freezing” of shares for trading purposes

B-1

at the custodian/sub-custodian bank level in order to vote proxies. While shares are frozen, they may not be traded. Therefore, the potential exists for a pending trade to fail if trade settlement falls on a date during the blocking period. In international markets where share blocking applies, FTA typically will not, but reserves the right to, vote proxies due to the liquidity constraints associated with share blocking.

(4)

On a regular basis, FTA Research reviews ISS recommendations on matters determined to have a potential impact of shareholder value to decide whether to vote as the Guidelines recommend and advises the FTA Investment Committee of its determination.

(5)

FTA may determine voting in accordance with the Guidelines is not in the best interests of a Proxy Client. Whenever a conflict of interest arises between ISS and a target company subject to a proxy vote, the Adviser will consider the recommendation of the company and what the Adviser believes to be in the best interests of the Proxy Client and will vote the proxy without using the Guidelines. If FTA has knowledge of a material conflict of interest between itself and a Proxy Client, the Adviser shall vote the applicable proxy in accordance with the Guidelines to avoid such conflict of interest. If there is a decision to vote against the Guidelines, the FTA Investment Committee will document the reason and instruct ISS to change the vote to reflect this decision.

If there is a conflict of interest between a Fund Proxy Client and FTA or other Fund service providers, FTA will vote the proxy based on the Guidelines to avoid such conflict of interest.

(6)

If a Proxy Client requests the Adviser to follow specific voting guidelines or additional guidelines, the Adviser shall review the request and follow such guidelines, unless the Adviser determines that it is unable to do so. In such case, the Adviser shall inform the Proxy Client that it is not able to honor the Proxy Client’s request.

(7)

FTA periodically reviews proxy votes to ensure compliance with this Policy.

(8)

This Policy, the Guidelines and votes cast for Proxy Clients are available upon request and such Proxy Client requests must be forwarded to FTA Compliance for review and response. This Policy is also provided with each advisory contract and described and provided with the Form ADV, Part 2A.

Shareholders of Fund Proxy Clients can review the Policy and a Fund’s voted proxies (if any) during the most recent 12-month period ended June 30 on the First Trust website at www.ftportfolios.com or by accessing EDGAR on the SEC website at www.sec.gov.

(9)

FTA provides reasonable ongoing oversight of ISS. FTA, or ISS on behalf of FTA, maintains the following records relating to proxy voting:

(a)

a copy of this Policy;

(b)

a copy of each proxy form for which it is responsible to vote;

(c)

a copy of each proxy solicitation, including proxy statements and related materials with regard to each proxy issue it votes;

(d)

documents relating to the identification and resolution of conflicts of interest, if any;

(e)

any documents created by FTA or ISS that were material to a proxy voting decision or that memorialized the basis for that decision; and

(f)

a copy of each written request from any Proxy Client for information on how FTA voted proxies on the Proxy Client’s behalf, and a copy of any written response by FTA to any written or oral request for information by a Proxy Client on how FTA voted proxies for that Proxy Client’s account.

These records are either maintained at FTA’s office or are electronically available to FTA through access to the ISS Proxy Exchange portal.

Section 9.5. Indemnification and Advancement of Expenses. Subject to the exceptions and limitations contained in this Section 9.5, every person who is, or has been, a Trustee, officer, or employee of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a "Covered Person"), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him or in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof.

No indemnification shall be provided hereunder to a Covered Person to the extent such indemnification is prohibited by applicable federal law.

The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person.

Subject to applicable federal law, expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under this Section 9.5 shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 9.5.

To the extent that any determination is required to be made as to whether a Covered Person engaged in conduct for which indemnification is not provided as described herein, or as to whether there is reason to believe that a Covered Person ultimately will be found entitled to indemnification, the Person or Persons making the determination shall afford the Covered Person a rebuttable presumption that the Covered Person has not engaged in such conduct and that there is reason to believe that the Covered Person ultimately will be found entitled to indemnification.

As used in this Section 9.5, the words "claim," "action," "suit" or "proceeding" shall apply to all claims, demands, actions, suits, investigations, regulatory inquiries, proceedings or any other occurrence of a similar nature, whether actual or threatened and whether civil, criminal, administrative or other, including appeals, and the words "liability" and "expenses" shall include without limitation, attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

First Trust Advisors L.P.
