First Trust Mortgage Income Fund (FMY)

Semi-Annual Letter from the Chairman and CEO

April 30, 2021

Dear Shareholders,

First Trust is pleased to provide you with the semi-annual report for the First Trust Mortgage Income Fund (the “Fund”), which contains detailed information about the Fund for the six months ended April 30, 2021.

I would like to begin my remarks by saying that this is a time for all of us to be thankful. It is astounding to me that our scientists and extended health care community successfully discovered, developed, and distributed multiple effective vaccines to treat the coronavirus (“COVID-19”) in the span of just 15 months. Suffice it to say that we are witnessing history in the making. We even received some good news recently with respect to wearing masks in public, a polarizing act for many politicians and Americans. The Centers for Disease Control and Prevention released a new set of guidelines in mid-May for those individuals who have been fully vaccinated. It essentially says fully vaccinated Americans can quit wearing their masks outdoors (even in crowds), in most indoor settings, and can drop social distancing altogether. This is a big step towards expediting the reopening of the U.S. economy.

For those who may not know, we subscribe to the buy-and-hold philosophy of investing here at First Trust Advisors L.P., even though it means enduring lots of tough times. While the notion of being able to time the market is seductive on its face, very few investors are skilled enough to make it work over time. I can think of no better example than the COVID-19 pandemic. The degree of uncertainty surrounding the onset of the virus alone was enough to make the average investor want to run for cover. And if that was not enough, the 33.8% plunge in the S&P 500^® Index (the “Index”) from February 19, 2020, through March 23, 2020 (23 trading days) was a real gut check for most of us. But a funny thing happened on the way to another potential collapse of the market − it did not happen. In fact, thanks to the U.S. Federal government stepping up with trillions of dollars of timely fiscal and monetary support, the stock market roared. From March 23, 2020 through May 14, 2021, the Index posted a total return of 90.14%, according to Bloomberg. What a shame for those investors who may have moved some, or all, of their capital out of equities. What looked like a great time to de-risk turned out to be just the opposite.

The overall climate for investing looks bright for a few reasons. First, U.S. real gross domestic product (“GDP”) growth is expected to grow by 6.4% year-over-year in 2021, according to the International Monetary Fund. The last time the U.S. economy grew that fast was in 1984, when real GDP growth reached 7.2%. Second, corporate earnings are expected to recover from their 2020 slide. Bloomberg’s consensus year-over-year earnings growth rate estimates for the Index for 2021 and 2022 were 33.17% and 12.87%, respectively, as of May 14, 2021. That is a significant rebound from the 12.44% decline in earnings in 2020. Third, inflation is rising, and that is exactly what the Federal Reserve has been wanting for some time. Central banks around the world have spent years battling deflationary pressures, so a little bit of inflation is welcome at this stage of the recovery. Lastly, the U.S. labor market is robust despite the talk about the millions of people who lost their jobs in the COVID-19 pandemic and are living off unemployment benefits. As of March 31, 2021, there were 8.12 million job openings in the U.S., the highest total since record-keeping began in December 2000, according to the Bureau of Labor Statistics. We need to get people back to work.

While it seems fashionable to sell fear these days, we choose to follow the data. Remember, the Index has never failed to fully recoup the losses sustained in a market correction or bear market. Stay the course!

Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.

Sincerely,

James A. Bowen

Chairman of the Board of Trustees

Chief Executive Officer of First Trust Advisors L.P.

Commentary

First Trust Mortgage Income Fund

The Fund’s primary investment objective is to seek a high level of current income. As a secondary objective, the Fund seeks to preserve capital. The Fund pursues its objectives by investing primarily in mortgage-backed securities (“MBS”) representing part ownership in a pool of either residential or commercial mortgage loans that, in the opinion of the Fund’s investment advisor, offer an attractive combination of credit quality, yield and maturity. There can be no assurance the Fund will achieve its investment objectives. The Fund may not be appropriate for all investors.

Market Recap

The 2021 fiscal year began in earnest as markets reacted to shifting and uncertain results surrounding U.S. elections. Meanwhile, the effects of the coronavirus (“COVID-19”) pandemic continued to ripple through both global and domestic economies alike. Post-election, on the back of incredibly positive vaccine developments, risk markets staged a very strong and very broad-based rally as market expectations for a faster economic recovery than earlier anticipated began to be priced into forward data. After another round of Federal stimulus, the calendar year turned over, election results were certified, and immediately the details of yet another round of an even larger scale stimulus program began to take shape. Market participants took notice, and when considering another massive stimulus bill alongside a blow out in M2 money supply during the pandemic, two factors weighed heavily on the intermediate and longer dated maturity segment of the U.S. yield curve – inflation and treasury debt issuance. Over the preceding 12 months, treasury issuance had already soared to buoy government deficit spending. Plans for additional rounds of stimulus only heightened fears of further treasury supply. As a result, the 5-Year Treasury sold off 46 basis points (“bps”), the 10-Year +75 bps and the 30-year +64 bps, while the 2-Year Treasury, firmly anchored by the Federal Reserve (the “Fed”), was basically unchanged. This drove the yield curve in the 2/10 (the 2-Year and 10-Year Treasury notes) 75 bps steeper to settle at 146 bps to end the fiscal period. As rates rose, yield hungry investors remained in an aggressive risk-on stance, as economic data showed the recovery was well underway. As such, Agency MBS spreads tightened dramatically, starting the period at 64 bps Option-Adjusted Spread (“OAS”), and ending the semi-annual period at -12 bps OAS.

Performance Analysis

During the first half of the 2021 fiscal year, the Fund returned 1.03% on a net asset value (“NAV”) basis, and 4.35% on a market price basis.

During the same period, the Bloomberg/Barclays US MBS Index (the “Index”) returned -0.27%.

During the same period, the Fund outperformed the Index by 1.30% net of fees, on a NAV basis and 4.62% on a market price basis. The Fund maintained significant exposures to Non-Agency Residential Mortgage-Backed Securities (“RMBS”), and Interest Only Agency MBS securities that continued to tighten over the period, which was a strong contributor to the outperformance. Additionally, the Fund maintained a lower, and more stable overall effective duration than its more negatively convex benchmark, which saw its duration extend as interest rates moved higher. The Fund’s usage of futures positions to help manage interest rate risk and to structurally position a lower overall effective duration, was mildly beneficial to the Fund’s performance. During the period, the Fund deployed a very minimal amount of leverage for a short period of time, which very minimally detracted from the Fund’s performance, as interest rates continued their sell off during the first quarter of 2021. The Fund continues to recover from the severe illiquidity that gripped financial markets in March of 2020. Since the NAV low on March 25, 2020, the Fund has outperformed its Agency MBS benchmark by more than 800 bps.

Fund and Market Outlook

As expected, we saw an acceleration in overall consumer and economic data to start the fiscal year. We expect strong and robust data over the remainder of the year as well, as the United States continues to fully reopen the economy. With the massive increase in M2 money supply, and with stimulus dollars in consumers’ hands, we do expect inflationary risks to continue to build. We are ever mindful

of the impacts this can have on term premium pricing along the U.S. yield curve, and believe heightened uncertainty will ultimately drive intermediate to long rates higher, before the Fed will confront how hot it wants the U.S. economy to run, and what magnitude of ongoing inflation it is comfortable within the economy. At the outset of the pandemic, the Fed deployed emergency rate cuts, large scale quantitative easing and unprecedented lending programs. Over one year later, it remains highly accommodative. We do anticipate that the Fed will begin to taper its bond purchasing program later this year, and potentially could implement a curve twist type program with the reinvestment of MBS paydowns back into U.S. treasuries. Overall, we believe that as long as the Fed maintains its view that inflation pressures are ‘transitory’, the front end of the yield curve will remain fairly anchored in place in the near term, with any rate volatility centralized in the intermediate to longer maturity segments. While we continue to redeploy capital into what we believe are attractively priced opportunities in the broader securitized mortgage market, we have turned negative on generic Agency MBS spread valuations, the types of securities of which constitute the majority of the Fund’s benchmark, and believe there is the potential for spread widening.

Given our outlook on the broader bond markets, we plan to continue to actively manage the Fund versus the Index from a duration standpoint. To the extent the curve sees a large bear steepening, likely due to inflationary pressures, treasury supply or volatility, we will look to take advantage of higher longer maturity yields and potentially look to increase interest rate hedges on the front end. From an asset allocation perspective, we plan to continue to reinvest legacy portfolio runoff into both Agency RMBS and Agency Commercial Mortgage-Backed Securities (“CMBS”) interest only securities. The Fund will also look to invest in select opportunities that the managers find to be attractively priced in Non-Agency CMBS and Non-Agency RMBS, with an emphasis on floating rate instruments. In our view, this approach would provide some yield, income, dividend, and spread protection for shareholders. As a reminder, as part of the investment team’s Agency MBS strategy, a substantial portion of the agency securities have been, and will continue to be, invested in the interest-only sectors to increase the income and economic earnings of the portfolio. This strategy can be very effective with proper security selection, particularly when combined with appropriate yield curve management. We plan to continue to maintain a tradeable portfolio as that is critical to being able to act should opportunities arise.

First Trust Mortgage Income Fund (FMY)

April 30, 2021 (Unaudited)

1. Organization

First Trust Mortgage Income Fund (the “Fund”) is a diversified, closed-end management investment company organized as a Massachusetts business trust on February 22, 2005, and is registered with the Securities and Exchange Commission (“SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund trades under the ticker symbol “FMY” on the New York Stock Exchange (“NYSE”).

The Fund’s primary investment objective is to seek a high level of current income. As a secondary objective, the Fund seeks to preserve capital. The Fund pursues its objectives by investing primarily in mortgage-backed securities (“MBS”) representing part ownership in a pool of either residential or commercial mortgage loans that, in the opinion of First Trust Advisors L.P. (“First Trust” or the “Advisor”), offer an attractive combination of credit quality, yield and maturity. There can be no assurance the Fund will achieve its investment objectives. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

A. Portfolio Valuation

The net asset value (“NAV”) of the Common Shares of the Fund is determined daily as of the close of regular trading on the NYSE, normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities and foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund’s NAV per Common Share is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses, dividends declared but unpaid and any borrowings of the Fund), by the total number of Common Shares outstanding.

The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Advisor’s Pricing Committee, in accordance with valuation procedures adopted by the Fund’s Board of Trustees, and in accordance with provisions of the 1940 Act. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund’s investments are valued as follows:

U.S. government securities, mortgage-backed securities, asset-backed securities and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Fund’s Board of Trustees, which may use the following valuation inputs when available:

1)	benchmark yields;
2)	reported trades;
3)	broker/dealer quotes;
4)	issuer spreads;
5)	benchmark securities;
6)	bids and offers; and
7)	reference data including market research publications.

Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Over-the-counter options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

April 30, 2021 (Unaudited)

Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:

1)	the credit conditions in the relevant market and changes thereto;
2)	the liquidity conditions in the relevant market and changes thereto;
3)	the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);
4)	issuer-specific conditions (such as significant credit deterioration); and
5)	any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Fund’s Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended (the “1933 Act”)) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

1)	the fundamental business data relating to the issuer;
2)	an evaluation of the forces which influence the market in which these securities are purchased and sold;
3)	the type, size and cost of the security;
4)	the financial statements of the issuer;
5)	the credit quality and cash flow of the issuer, based on the Advisor’s or external analysis;
6)	the information as to any transactions in or offers for the security;
7)	the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8)	the coupon payments;
9)	the quality, value and salability of collateral, if any, securing the security;
10)	the business prospects of the issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the issuer’s management;
11)	the prospects for the issuer’s industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry; and
12)	other relevant factors.

The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.

April 30, 2021 (Unaudited)

o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•	Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund’s investments as of April 30, 2021, is included with the Fund’s Portfolio of Investments.

B. Option Contracts

The Fund may invest in exchange-listed options on U.S. Treasury securities, exchange-listed options on U.S. Treasury futures contracts and exchange-listed U.S. Treasury futures contracts. The Fund uses derivative instruments primarily to hedge interest rate risk and actively manage interest rate exposure. The primary risk exposure is interest rate risk.

The Fund may purchase (buy) or write (sell) put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option contract may be closed out by an offsetting purchase or sale of a futures option of the same series. When the Fund writes (sells) an option, an amount equal to the premium received by the Fund is included in “Options contracts written, at value” on the Statement of Assets and Liabilities. When the Fund purchases (buys) an option, the premium paid represents the cost of the option, which is included in “Premiums paid on options contracts purchased” on the Statement of Assets and Liabilities. Options are marked-to-market daily and their value is affected by changes in the value of the underlying security, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying securities, and the remaining time to the option’s expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or the trading volume diminishes.

The Fund uses options on futures contracts in connection with hedging strategies. Generally, these strategies are applied under the same market and market sector conditions in which the Fund uses put and call options on securities. The purchase of put options on futures contracts is analogous to the purchase of puts on securities so as to hedge the Fund’s securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities which are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund’s holdings of securities. If the price when the option is exercised is above the exercise price, however, the Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Fund intends to acquire. Realized gains and losses on written options are included in “Net realized gain (loss) on written options contracts” on the Statement of Operations. Realized gains and losses on purchased options are included in “Net realized gain (loss) on purchased options contracts” on the Statement of Operations.

The Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by the Fund. The Fund will pledge in a segregated account at the Fund’s custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be pledged in the segregated account whenever the total value of the pledged assets falls below the amount due on the underlying obligation.

The risks associated with the use of options on future contracts include the risk that the Fund may close out its position as a writer of an option only if a liquid secondary market exists for such options, which cannot be assured. The Fund’s successful use of options on futures contracts depends on the Advisor’s ability to correctly predict the movement in prices on futures contracts and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to option.

C. Securities Transactions and Investment Income

Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.

The Fund invests in interest-only securities. For these securities, if there is a change in the estimated cash flows, based on an evaluation of current information, then the estimated yield is adjusted. Additionally, if the evaluation of current information indicates a permanent impairment of the security, the cost basis of the security is written down and a loss is recognized. Debt obligations may be placed on non-accrual status and the related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At April 30, 2021, the Fund had no when-issued, delayed-delivery or forward purchase commitments.

The United Kingdom’s Financial Conduct Authority, which regulates the London Interbank Offered Rates (“LIBOR”), announced on March 5, 2021 that all non-USD LIBOR reference rates and the 1-week and 2-month USD LIBOR reference rates will cease to be provided or no longer be representative immediately after December 31, 2021 and the remaining USD LIBOR settings will cease to be provided or no longer be representative immediately after June 30, 2023.

(“ISDA”) confirmed that the March 5, 2021 announcement constituted an index cessation event under the Interbank Offered Rates (“IBOR”) Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks Protocol for all 35 LIBOR settings and confirmed that the spread adjustment to be used in ISDA fallbacks was fixed as of the date of the announcement.

In the United States, the Alternative Reference Rates Committee (the “ARRC”), a group of market participants convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York in cooperation with other federal and state government agencies, has since 2014 undertaken efforts to identify U.S. dollar reference interest rates as alternatives to LIBOR and to facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC identified the Secured Overnight Financing Rate (“SOFR”), a broad measure of the cost of cash overnight borrowing collateralized by U.S. Treasury securities, as the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New York began daily publishing of SOFR in April 2018.

At this time, it is not possible to predict the full impact of the elimination of LIBOR and the establishment of an alternative reference rate on the Fund or its investments.

D. Futures Contracts

The Fund may purchase or sell (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in “Net realized gain (loss) on futures contracts” on the Statement of Operations.

Upon entering into a futures contract, the Fund must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked to market daily with the change in value recognized as a component of “Net change in unrealized appreciation (depreciation) on futures contracts” on the Statement of Operations. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are included in “Variation margin” payable or receivable on the Statement of Assets and Liabilities.

If market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments.

Restricted cash segregated as collateral for futures contracts in the amount of $38,214 is shown as “Restricted Cash” on the Statement of Assets and Liabilities.

E. Inverse Floating-Rate Securities

An inverse floating-rate security is one where the coupon is inversely indexed to a short-term floating interest rate multiplied by a specific factor. As the floating rate rises, the coupon is reduced. Conversely, as the floating rate declines, the coupon is increased. The price of these securities may be more volatile than the price of a comparable fixed-rate security. These instruments are typically used to enhance the yield of the portfolio and have the effect of creating leverage. These securities, if any, are identified on the Portfolio of Investments.

F. Stripped Mortgage-Backed Securities

Stripped Mortgage-Backed Securities are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security’s principal or interest payments. Mortgage securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security known as an interest-only security (“IO Security”) and all of the principal is distributed to holders of another type of security known as a principal-only security. These securities, if any, are identified on the Portfolio of Investments.

G. Interest-Only Securities

An IO Security is the interest-only portion of a mortgage-backed security that receives some or all of the interest portion of the underlying mortgage-backed security and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due to the IO Security. IO Securities are sold at a deep discount to their notional principal amount. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of an IO Security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of an IO Security will rise. These securities, if any, are identified on the Portfolio of Investments.

H. Mortgage Dollar Rolls and TBA Transactions

The Fund may invest, without limitation, in mortgage dollar rolls. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Fund’s investment advisor. In a mortgage dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. Mortgage dollar rolls are recorded as separate purchases and sales in the Fund. The Fund may also invest in to-be-announced transactions (“TBA Transactions”). A TBA Transaction is a method of trading mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price.

I. Dividends and Distributions to Shareholders

The Fund will distribute to holders of its Common Shares monthly dividends of all or a portion of its net income after the payment of interest and dividends in connection with leverage, if any. Distributions of any net long-term capital gains earned by the Fund are distributed at least annually. Distributions will automatically be reinvested into additional Common Shares pursuant to the Fund’s Dividend Reinvestment Plan unless cash distributions are elected by the shareholder.

Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Fund and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some point in the future.

The tax character of distributions paid by the Fund during the fiscal year ended October 31, 2020, was as follows:

Distributions paid from:
Ordinary income	$2,663,075
Capital gains	—
Return of capital	370,368

As of October 31, 2020, the components of distributable earnings and net assets on a tax basis were as follows:

Undistributed ordinary income	$—
Undistributed capital gains	—
Total undistributed earnings	—
Accumulated capital and other losses	(2,755,463)
Net unrealized appreciation (depreciation)	(2,646,536)
Total accumulated earnings (losses)	(5,401,999)
Other	—
Paid-in capital	66,279,669
Total net assets	$60,877,670

J. Income Taxes

The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, the Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of the Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses arising in taxable years after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At October 31, 2020, the Fund had no pre-enactment net capital losses for federal income tax purposes. At October 31, 2020, the Fund had post-enactment net capital losses for federal income tax purposes of $2,755,463 to be carried forward indefinitely.

The Fund is subject to certain limitations under the U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership.

Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended October 31, 2020, the Fund did not incur any net ordinary losses.

The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of April 30, 2021, management has evaluated the application of these standards to the Fund and has determined that no provision for income tax is required in the Fund’s financial statements for uncertain tax positions.

K. Expenses

The Fund will pay all expenses directly related to its operations.

3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements

First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the Fund’s investment portfolio, managing the Fund’s business affairs and providing certain administrative services necessary for the management of the Fund. For these investment management services, First Trust is entitled to a monthly fee calculated at an annual rate of 0.85% of the Fund’s Managed Assets (the average daily total asset value of the Fund minus the sum of the Fund’s liabilities other than the principal amount of borrowings or reverse repurchase agreements, if any). First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250.

BNY Mellon Investment Servicing (US) Inc. (“BNYM IS”) serves as the Fund’s transfer agent in accordance with certain fee arrangements. As transfer agent, BNYM IS is responsible for maintaining shareholder records for the Fund. The Bank of New York Mellon (“BNYM”) serves as the Fund’s administrator, fund accountant, and custodian in accordance with certain fee arrangements. As administrator and fund accountant, BNYM is responsible for providing certain administrative and accounting services to the Fund, including maintaining the Fund’s books of account, records of the Fund’s securities transactions, and certain other books and records.

As custodian, BNYM is responsible for custody of the Fund’s assets. BNYM IS and BNYM are subsidiaries of The Bank of New York Mellon Corporation, a financial holding company.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a defined-outcome fund or an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and “Interested” Trustee receive no compensation from the Fund for acting in such capacities.

4. Purchases and Sales of Securities

The cost of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2021, were $10,514,563 and $6,061,163, respectively. The proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2021, were $9,042,899 and $7,425,721, respectively. The cost of purchases to cover investments sold short and the proceeds of investments sold short were $1,003,516 and $1,003,516, respectively.

Dividend Reinvestment Plan

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), unless you elect, by written notice to the Fund, to receive cash distributions, all dividends, including any capital gain distributions, on your Common Shares will be automatically reinvested by BNY Mellon Investment Servicing (US) Inc. (the “Plan Agent”), in additional Common Shares under the Plan. If you elect to receive cash distributions, you will receive all distributions in cash paid by check mailed directly to you by the Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1)

If Common Shares are trading at or above net asset value (“NAV”) at the time of valuation, the Fund will issue new shares at a price equal to the greater of (i) NAV per Common Share on that date or (ii) 95% of the market price on that date.

(2)

If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date except where temporary curtailment or suspension of purchases is necessary to comply with federal securities laws. Interest will not be paid on any uninvested cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving written notice to the Plan Agent, or by telephone at (866) 340-1104, in accordance with such reasonable requirements as the Plan Agent and the Fund may agree upon. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan, and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions.

The Plan Agent maintains all Common Shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. The Plan Agent will forward to each participant any proxy solicitation material and will vote any shares so held only in accordance with proxies returned to the Fund. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Capital gains and income are realized although cash is not received by you. Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing BNY Mellon Investment Servicing (US) Inc., 301 Bellevue Parkway, Wilmington, Delaware 19809.

In addition, the Fund’s reports to the SEC on Form N-CSR contain certifications by the Fund’s principal executive officer and principal financial officer that relate to the Fund’s public disclosure in such reports and are required by Rule 30a-2 under the 1940 Act.

Submission of Matters to a Vote of Shareholders

The Fund held its Annual Meeting of Shareholders (the “Annual Meeting”) on April 26, 2021. At the Annual Meeting, Richard E. Erickson and Thomas R. Kadlec were elected by the Common Shareholders of First Trust Mortgage Income Fund as the Class II Trustees for a three-year term expiring at the Fund’s annual meeting of shareholders in 2024. The number of votes cast in favor of Mr. Erickson was 2,112,383 and the number of votes withheld was 289,605. The number of votes cast in favor of Mr. Kadlec was 2,110,797 and the number of votes withheld was 291,191. James A. Bowen, Niel B. Nielson, and Robert F. Keith are the other current and continuing Trustees.

Principal Risks

The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The following discussion summarizes the principal risks associated with investing in the Fund, which includes the risk that you could lose some or all of your investment in the Fund. The Fund is subject to the informational requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940 and, in accordance therewith, files reports, proxy statements and other information that is available for review.

Collateralized Mortgage Obligations Risks. A risk of CMOs is the uncertainty of the timing of cash flows that results from the rate of prepayments on the underlying mortgages serving as collateral and from the structure of the particular CMO transaction (that is, the priority of the individual tranches). An increase or decrease in prepayment rates (resulting from a decrease or increase in mortgage interest rates) may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates and will affect the yield and price of CMOs. In addition, if the collateral securing CMOs or any third-party guarantees are insufficient to make payments, the Fund could sustain a loss.

Credit Agency Risk. Credit ratings are determined by credit rating agencies 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.

Credit and Below-Investment Grade Securities Risk. Credit risk is the risk that the issuer of one or more securities in the Fund’s portfolio will fail to pay dividends or interest or repay principal when due. Below-investment grade instruments, including instruments that are not rated but judged to be of comparable quality, are commonly referred to as high-yield securities or “junk” bonds and are considered speculative with respect to the issuer’s capacity to pay dividends or interest and repay principal and are susceptible to default or decline in market value due to adverse economic and business developments. High-yield securities are often unsecured and subordinated to other creditors of the issuer. The market values for high-yield securities tend to be very volatile, and these securities are generally less liquid than investment grade securities. For these reasons, an investment in the Fund is subject to the following specific risks: (i) increased price sensitivity to changing interest rates and to a deteriorating economic environment; (ii) greater risk of loss due to default or declining credit quality; (iii) adverse company specific events more likely to render the issuer unable to make dividend, interest and/or principal payments; (iv) negative perception of the high-yield market which may depress the price and liquidity of high-yield securities; (v) volatility; and (vi) liquidity.

Cyber Security Risk. The Fund is susceptible to potential 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

Page 24

Table of Contents

Additional Information (Continued)

First Trust Mortgage Income Fund (FMY)

April 30, 2021 (Unaudited)

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 Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the Fund invests, can also subject the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, 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.

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 their market value 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.

Fixed-Income Securities Risk. An investment in fixed-income securities is subject to certain risks, including:

•	Issuer Risk. The value of fixed-income 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. In addition, an issuer of fixed-income securities may default on its obligation to pay interest and repay principal.
•	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.
•	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 securities or loans at market interest rates that are below the Fund portfolio’s current earnings rate.

Futures Contracts Risk. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of the instruments or indices underlying the futures contracts and the price of the futures contracts; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the investment adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

Illiquid and Restricted Securities Risk. Investments in restricted securities could have the effect of increasing the amount of the Fund’s assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase these securities. Illiquid and restricted securities may be difficult to dispose of at a fair price at the times when the Fund believes it is desirable to do so. The market price of illiquid and restricted securities generally is more volatile than that of more liquid securities, which may adversely affect the price that the Fund pays for or recovers upon the sale of such securities. Illiquid and restricted securities are also more difficult to value, especially in challenging markets.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money.

Interest Rate and Duration Risk. Interest rate risk is the risk that securities will decline in value because of changes in market interest rates. For fixed income securities, when market interest rates rise, the market value of such securities generally will fall. 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. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations. Investments in fixed rate securities with long-term maturities may experience significant price declines if long-term interest rates increase.

The interest rates payable on floating rate securities are not fixed and may fluctuate based upon changes in market rates. As short-term interest rates decline, interest payable on floating rate securities typically decreases. Alternatively, during periods of rising interest rates, interest payable on floating rate securities typically increases. Changes in interest rates on floating rate securities may lag behind changes in market rates or may have limits on the maximum increases in interest rates. The value of floating rate securities may decline if their interest rates do not rise as much, or as quickly, as interest rates in general.

Many financial instruments use or may use a floating rate based upon the London Interbank Offered Rate (“LIBOR”). The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, intends to cease making LIBOR available as a reference rate over a phase-out period that is currently expected to begin after the end of 2021. The unavailability or replacement of LIBOR may affect the

Page 25

Table of Contents

Additional Information (Continued)

First Trust Mortgage Income Fund (FMY)

April 30, 2021 (Unaudited)

value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the Fund or on certain instruments in which the Fund invests can be difficult to ascertain, and they may vary depending on a variety of factors. Any such effects on the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Inverse floating rate securities generally will underperform the market for fixed rate securities in a rising interest rate environment. An inverse floating rate security’s price may be more volatile than that of a fixed rate security.

In the case of stripped mortgage-backed securities, in general, when interest rates are falling and prepayment rates are increasing, the value of a principal only security (“PO Security”) will rise and the value of an interest only security (“IO Security”) will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, in general, the value of a PO Security will fall and the value of an IO Security will rise.

Leverage Risk. The use of leverage by the Fund can magnify the effect of any losses. If the income and gains from the securities and investments purchased with leverage proceeds do not cover the cost of leverage, the return to the common shares will be less than if leverage had not been used. Leverage involves risks and special considerations for common shareholders including: the likelihood of greater volatility of net asset value and market price of the common shares than a comparable portfolio without leverage; the risk that fluctuations in interest rates on borrowings will reduce the return to the common shareholders or will result in fluctuations in the dividends paid on the common shares; in a declining market, the use of leverage is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares; and when the Fund uses certain types of leverage, the investment advisory fee payable to the Advisor and by the Advisor to the Sub-Advisor will be higher than if the Fund did not use leverage.

Management Risk and Reliance on Key Personnel. The implementation of the Fund’s investment strategy depends upon the continued contributions of certain key employees of the Advisor, some of whom have unique talents and experience and would be difficult to replace. The loss or interruption of the services of a key member of the portfolio management team could have a negative impact on the Fund.

Market Discount from Net Asset Value. Shares of closed-end investment companies such as the Fund frequently trade at a discount from their net asset value. The Fund cannot predict whether its common shares will trade at, below or above net asset value.

Market Risk. Securities held by the Fund, as well as shares of the Fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, 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 as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. The COVID-19 pandemic may last for an extended period of time and will continue to impact the economy for the foreseeable future.

Mortgage-Backed Securities Risk. A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security and the structure of its issuer. For example, if a mortgage underlying a particular mortgage-backed security defaults, the value of that security may decrease. Moreover, a downturn in the markets for residential or commercial real estate or a general economic downturn could negatively affect both the price and liquidity of privately issued mortgage-backed securities. Mortgage-backed securities are subject to prepayment risk, which is the risk that the borrowers under the mortgage loans underlying a Fund’s mortgage-backed securities might pay off their mortgage loans sooner than expected, which could happen when interest rates fall or for other reasons, which could cause the value of the Fund’s mortgage-backed securities to fall. Moreover, if the underlying mortgage loans are paid off sooner than expected, the Fund may have to reinvest the proceeds in other securities that have lower yields. Mortgage-backed securities are also subject to extension risk, which is the risk that rising interest rates could cause mortgages underlying the securities to be prepaid more slowly than expected, resulting in slower prepayments of the securities. This would, in effect, convert a short or medium-duration mortgage-backed security into a longer-duration security, increasing its sensitivity to interest rate changes and likely causing its price to decline. Mortgage-backed securities issued by a private issuer, such as commercial mortgage-backed securities, generally entail greater risk than obligations directly or indirectly guaranteed by the U.S. government or a government-sponsored entity.

A portion of the Fund’s managed assets may be invested in subordinated classes of mortgage-backed securities. Such subordinated classes are subject to a greater degree of non-payment risk than are senior classes of the same issuer or agency. In addition, under

certain market conditions, the market for subordinated classes of mortgage-backed securities may not be as liquid as the market for other fixed income securities.

Given its focus in mortgage-backed securities, the Fund may be more susceptible to adverse economic, political and regulatory events that affect the value of real estate.

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.

Potential Conflicts of Interest Risk. First Trust and the portfolio managers have interests which may conflict with the interests of the Fund. In particular, First Trust currently manages and may in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objectives and strategies as the Fund. In addition, while the Fund is using leverage, the amount of the fees paid to First Trust for investment advisory and management services are higher than if the Fund did not use leverage because the fees paid are calculated based on managed assets. Therefore, First Trust has a financial incentive to leverage the Fund.

Repurchase Agreement Risk. A repurchase agreement is an agreement to purchase a security from a party at one price and a simultaneous agreement to sell it back to the original party at an agreed-upon price, typically representing the purchase price plus interest. Repurchase agreements are subject to the risk of failure. If the Fund’s counterparty defaults on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss.

Short Selling Risk. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. Because losses on short sales arise from increases in the value of the security sold short, such losses are theoretically unlimited. It is possible that the Fund’s long securities positions will decline in value at the same time that the value of its short securities positions increase, thereby increasing potential losses to the Fund. In addition, the Fund’s short selling strategies will limit its ability to fully benefit from increases in the fixed-income markets. The Fund may not be able to borrow a security that it needs to deliver or it may not be able to close out a short position at an acceptable price and may have to sell related long positions before it had intended to do so. Thus, the Fund may not be able to successfully implement its short sale strategy due to limited availability of desired securities or for other reasons. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund.

TBA Transactions Risk. The Fund may purchase securities via TBA (To Be Announced) Transactions. In such a transaction, the purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchasing securities in a TBA Transaction may give rise to investment leverage and may increase the Fund’s volatility. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction.

Valuation Risk. The valuation of mortgage-backed securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. The Fund may hold investments in sizes smaller than institutionally‐sized round lot positions (sometimes referred to as odd lots). However, third‐party pricing services generally provide evaluations on the basis of institutionally‐sized round lots. If the Fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities have been held by the Fund. Odd lots often trade at lower prices than institutional round lots.
