First Trust Mortgage Income Fund (FMY)

Annual Letter from the Chairman and CEO

October 31, 2022

Dear Shareholders,

First Trust is pleased to provide you with the annual report for the First Trust Mortgage Income Fund (the “Fund”), which contains detailed information about the Fund for the twelve months ended October 31, 2022.

As I’m writing this letter in mid-November, it strikes me that things appear to be a little more chaotic in the current climate than normal. One of the things that may have contributed to the chaotic nature of the news flow of late was the November mid-term election. For the most part, except for a few seats in Congress, the election is behind us. We learned there would be no “red wave” (Republicans gaining a strong majority in Congress) but likely gridlock ahead. Gridlock has been good for stock market investors in the past few decades, particularly when there’s been a Democratic president and the Republicans have control of at least one house of Congress, according to Brian Wesbury, Chief Economist at First Trust.

The Federal Reserve (the “Fed”) has kept its promise to aggressively hike interest rates to combat robust inflation. As of November 13, 2022, the Fed has increased the Federal Funds target rate (upper bound) six times, from 0.25% to 4.00%. The Fed’s actions have some investors and pundits looking for evidence linking the interest rate hikes to a downturn in the economy. In short, the hope is that a pullback in economic activity might deter the Fed from executing further interest rate hikes. Fed Chairman Jerome Powell, however, recently said that the terminal rate (the ultimate rate the Fed is targeting) will likely need to be higher than previously estimated in order to curb stubbornly high inflation. The Consumer Price Index (“CPI”) is a commonly used measure of inflation. The CPI stood at 7.7% on a trailing 12-month basis as of October 31, 2022, according to the U.S. Bureau of Labor Statistics. That is down from its recent high of 9.1% in June 2022. Prior to this year, the last time the CPI was higher than 7.0% was over 40 years ago. While monetary policy is an ongoing process subject to change, the Fed does appear to be steadfast in its mission to bring the rate of inflation back to its preferred level of 2.0%, and that will take some time, in my opinion. Stay tuned!

Equity and fixed income markets have contended with numerous headwinds this year, such as the war between Russia and Ukraine. Since setting its all-time high of 4,796.56 on January 3, 2022, the S&P 500^® Index has been in a bear market (a price decline of 20% or more from the most recent high) for the better part of 310 days. Suffice it to say, we are all looking forward to the end of this bear market. With respect to corrections and bear markets, the silver lining is that the S&P 500^®Index has never failed to fully recover the losses sustained in any previous downturn. Where might we see demand for stocks moving forward? One such source could be stock buybacks. As of the last week of October 2022, U.S. companies had announced stock buybacks totaling $1 trillion so far this year, according to Birinyi Associates. The fixed income market has not been immune to selling pressure either. Year-to-date through November 10, 2022, yields on the 10-Year Treasury Note increased by 258 basis points. As you may be aware, bond yields and bond prices are inversely related, particularly with respect to investment-grade bonds. As yields rise, prices fall and vice versa. As noted above, the Fed has more work to do, so bond investors should not be surprised to see interest rates and bond yields trend at least a bit higher in the months ahead.

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 12-month period ended October 31, 2022 began with markets coming under pressure as measures of inflation began to accelerate upward, and market participants questioning whether inflation was truly transitory, as so proclaimed by the Federal Reserve (the “Fed”). In a continuation of the yield curve repricing following the September 2021 Federal Open Market Committee (“FOMC”) meeting, bond yields once again resumed their march higher as the calendar year flipped into 2022, as fears of the Omicron variant of the coronavirus (“COVID-19”) were pushed aside, broader economic data remained strong, and incoming inflation data was rapidly deteriorating. Finally, the Fed relented and abandoned its transitory language, began to pivot and signaled very hawkish monetary policy to come. This hawkish pivot included guidance on not only an aggressive path of future rate hikes, but also signaled the use of the balance sheet to finally conclude new purchases of U.S. Treasuries and Agency MBS and subsequently, to let the securities mature and roll off via Quantitative Tightening. Unfortunately for the Fed and the broader U.S. economy, inflationary readings continued to push higher, and the Fed was forced, albeit clearly too late in its action, in our view, to act very aggressively. This started in June 2022 with the first 75 basis point (“bps”) hike in nearly thirty years and was followed by successive 75 bps hikes at the July and September 2022 meetings. This abrupt monetary policy change kicked off rather sharp moves higher in interest rates, volatility, and risk asset pricing, with each coming under duress throughout the 2022 calendar year. Over the course of the fiscal year, 2-Year treasury yields rose +399 bps, 5-Year treasury yields rose +305 bps, and 10-Year treasury yields rose +243 bps. These dramatic rate increases caused measures of volatility to spike, with the Merrill Lynch Option Volatility Estimate Index increasing to levels not seen since the Great Financial Crisis of 2008 (“GFC”). With upward pressure in interest rates and sustained rate volatility, overall risk asset pricing and market liquidity have come under significant pressure. Over the period, securitized spreads have widened with the Agency mortgage basis closing at +175 bps on October 31, 2022, which is +111 bps wider and the government option-adjusted spread on Agency MBS widening 45 bps to close the period at 49 bps, with a period high of 64 bps.

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance. Performance in securitized product investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size.

For the 12-month period ended October 31, 2022, the Fund returned -8.38% on a net asset value (“NAV”) basis.

During the same period, the Bloomberg U.S. MBS Index (the “Index”) returned -15.04%.

During the same period, the Fund outperformed the Index by 6.66% net of fees, on a NAV basis.

Given the historic ascent of home price appreciation the U.S. housing market experienced in late 2020 and throughout 2021, the Fund elected to reduce its non-Agency residential mortgage-backed securities (“RMBS”) holdings during the period. We believed that housing would cool on both a nominal as well as real basis, as interest rates increased and put significant pressure on affordability of housing stock. Additionally, the Fund continued to reduce its allocations to various Agency MBS sectors, namely pass-throughs and collateralized mortgage obligations. Proceeds from the reductions in Non-Agency RMBS and Agency MBS were reallocated into select Non-Agency commercial mortgage-backed securities and asset-back securities sectors, with a particular focus on short duration and floating rate opportunities. Additionally, there were periods that the Fund built and held more cash than normal, as we believe there would be better entry points for select risk assets. We thought that this was a prudent reallocation of risk as the Fund reduced exposure to assets that we believed would feel more impact from a slowing housing market and on the Agency side, assets we felt were more exposed to any Fed taper or additional rate increases. We believe this reallocation provided the Fund a significant pickup in

spread, helped maintain a very short duration, and allowed the Fund to more easily achieve its primary objective of a high level of current income. Additionally, throughout the period, the Fund maintained a significantly lower, and more stable overall effective duration than its more negatively convex Index, which saw its duration extend as interest rates moved higher. Combined, these strategies helped to drive the relative outperformance, which saw the Fund outperform the Index by over 600 bps on a NAV basis calendar, year-to-date. Additionally, the Fund’s usage of futures positions to help manage interest rate risk and to structurally position a lower overall effective duration was beneficial to the Fund’s performance as interest rates rose. Over the course of the 12-month period ended October 31, 2022, the Fund deployed a very minimal amount of leverage for a short period of time, which had a negligible effect on the Fund’s performance.

The Fund has a practice of seeking to maintain a relatively stable monthly distribution, which may be changed at any time. The practice has no impact on the Fund’s investment strategy and may reduce the Fund’s NAV. However, the Advisor believes the practice helps maintain the Fund’s competitiveness and may benefit the Fund’s market price and premium/discount to the Fund’s NAV. The monthly distribution rate began the period at $0.0550 per share and ended at $0.0550 per share. At the $0.0550 per share monthly distribution rate, the annualized distribution rate at October 31, 2022 was 5.46% at NAV and 5.99% at market price. For the 12-month period ended October 31, 2022, 65.45% of the distributions were characterized as ordinary income and 34.55% of the distributions were characterized as return of capital. The final determination of the source and tax status of all 2022 distributions will be made after the end of 2022 and will be provided on Form 1099-DIV. Not to be construed as tax advice. Please consult your tax advisor for further information regarding tax matters.

Fund and Market Outlook

As expected, on the back of a massive increase in M2 money supply, limited housing inventory coupled with historically low rates, ongoing supply chain delays and labor market shortages, inflationary pressure built to levels not seen in 40 years. We remain mindful of both how hard it can be to tame inflation once set in, and the impacts inflation can have on term premium pricing along the U.S. Treasury yield curve. And while we believe that it won’t be a straight line, we believe yields across the curve will continue to move higher, albeit at a much slower pace than experienced earlier this year. We believe the Fed may be forced to hike higher than the market expects, and as such believe that the curve inversion will continue to persist, although we do not expect significantly deeper inversion. Inflation remains high, however we believe follow through from the aggressive rate hikes implemented over the last several months have just begun to work their way through the broader economy, and already, it appears the housing market is beginning to cool off as month-over-month home price appreciation has turned negative. Currently, we do not believe the Fed will be an outright seller of its MBS holdings for long as measures of volatility and illiquidity remain this elevated. We do anticipate that heightened levels of rate volatility will remain over the shorter term, however, we believe that to expect measures of rate volatility and spread pricing to simply return to post-GFC/pre-Covid-19 levels in the near term and perhaps even intermediate term, would be unrealistic. Heavy handed Fed intervention appears to be over for now; however, for as long as inflation persists, the Fed appears committed to the fight. Despite the moderately bearish tone on rates, spreads are quite wide, and we believe opportunities abound, as we are now very positive on generic Agency MBS spread valuations, along with AAA shorter duration securitized opportunities.

We remain committed to finding value across the various sectors of the mortgage and securitized market, but also along the term spectrum of the U.S. yield curve. Given the massive increase in interest rates this year, we have begun to increase the interest rate sensitivity in the Fund as duration risks look more balanced, in our opinion, than earlier in the year, and should yields continue to climb, we will likely continue to extend duration. We remain committed to actively managing the convexity component in the portfolio and will look to continue to manage the Fund to a more stable duration target than the Index, meaning we do not want the bonds in the portfolio to extend in duration as rates rise, and conversely, we do not want to shorten or lose duration into a rally. From an asset allocation perspective, we plan to take advantage of very wide spreads in select securitized opportunities that the managers find to be attractively priced in the short to intermediate part of the curve, which we find to be particularly attractive in light of the current curve inversion. In our view, this approach would provide higher current yield, income, dividend, and spread protection for shareholders. As a reminder, as part of the investment team’s ongoing Agency MBS strategy, a portion of the agency securities have been and will continue to be invested in the interest-only sectors in an attempt to increase the income and economic earnings of the portfolio. We believe this strategy can be very effective with proper security selection, particularly when combined with appropriate yield curve management. Given the amount of rate increases already experienced across the curve, and with expectations for more, we anticipate the Interest Only component of the portfolio to perform well. 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)

October 31, 2022

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 readily available market quotations such as 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 approved by the Fund’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. 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.

Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

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 valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

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

Page 17

Table of Contents

Notes to Financial Statements (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022

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 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) 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.
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.

October 31, 2022

•	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 October 31, 2022, is included with the Fund’s Portfolio of Investments.

In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act, establishing requirements to determine fair value in good faith for purposes of the 1940 Act. The rule permits fund boards to designate a fund’s investment adviser to perform fair value determinations, subject to board oversight and certain other conditions. The rule also defines when market quotations are “readily available” for purposes of the 1940 Act and requires a fund to fair value a portfolio investment when a market quotation is not readily available. The SEC also adopted new Rule 31a-4 under the 1940 Act, which sets forth recordkeeping requirements associated with fair value determinations. The compliance date for Rule 2a-5 and Rule 31a-4 was September 8, 2022.

Effective September 8, 2022 and pursuant to the requirements of Rule 2a-5, the Fund’s Board of Trustees designated the Advisor as its valuation designee to perform fair value determinations and approved new Advisor Valuation Procedures for the Fund.

B. 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 October 31, 2022, the Fund had no when-issued, delayed-delivery or forward purchase commitments.

The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates the London Interbank Offered Rates (“LIBOR”), announced on March 5, 2021 that it intended to phase-out all LIBOR reference rates, beginning December 31, 2021. Since that announcement, the FCA has ceased publication of all non-USD LIBOR reference rates and the 1-week and 2-month USD LIBOR reference rates as of December 31, 2021. The remaining USD LIBOR settings will cease to be published or no longer be representative immediately after June 30, 2023. The International Swaps and Derivatives Association, Inc. (“ISDA”) confirmed that the FCA’s March 5, 2021 announcement of its intention to cease providing LIBOR reference rates, 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. There is no assurance that any alternative reference rate, including SOFR, will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity.

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.

C. 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

Page 19

Table of Contents

Notes to Financial Statements (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022

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 $153,871 is shown as “Restricted Cash” on the Statement of Assets and Liabilities.

D. 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.

E. 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.

F. 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.

G. 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.

H. 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. Permanent differences incurred during the fiscal year ended October 31, 2022, resulting in book and tax accounting differences, have been reclassified at year end to reflect a decrease in accumulated net investment income (loss) of $1,369,047 and an increase in accumulated net realized gain (loss) of $1,369,047. Accumulated distributable earnings (loss) consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments, and unrealized appreciation (depreciation) on investments. Net assets were not affected by this reclassification.

The tax character of distributions paid by the Fund during the fiscal years ended October 31, 2022 and 2021, was as follows:

Distributions paid from:	2022	2021
Ordinary income	$1,819,898	$1,462,301
Capital gains	—	—
Return of capital	960,758	1,571,142

As of October 31, 2022, 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	(1,735,178)
Net unrealized appreciation (depreciation)	(11,083,415)
Total accumulated earnings (losses)	(12,818,593)
Other	—
Paid-in capital	63,747,769
Total net assets	$50,929,176

I. 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.

The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Fund is subject to certain limitations under 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. At October 31, 2022, the Fund had non-expiring capital loss carryforwards available for federal income tax purposes of $1,735,178.

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, 2022, the Fund did not incur any net late year 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 2019, 2020, 2021, and 2022 remain open to

federal and state audit. As of October 31, 2022, 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.

As of October 31, 2022, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows:

Tax Cost		Gross Unrealized Appreciation		Gross Unrealized (Depreciation)		Net Unrealized Appreciation (Depreciation)
$61,357,730		$175,013		$(11,258,428)		$(11,083,415)

J. 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”) served as the Fund’s transfer agent in accordance with certain fee arrangements until December 31, 2021. Effective December 31, 2021, Computershare, Inc. (“Computershare”) commenced serving as the Fund’s transfer agent. As transfer agent, Computershare is responsible for maintaining shareholder records for the Fund.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of First Trust Mortgage Income Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of First Trust Mortgage Income Fund (the “Fund”), including the portfolio of investments, as of October 31, 2022, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of October 31, 2022, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of October 31, 2022, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

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 Computershare Trust Company N.A. (the “Plan Agent”), in additional Common Shares under the Plan. BNY Mellon Investment Servicing (US) Inc. served as the Plan Agent until December 31, 2021. Effective December 31, 2021, Computershare Trust Company N.A. commenced serving as the Fund’s Plan Agent. 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 Computershare, Inc., P.O. Box 505000, Louisville, KY 40233-5000.

Investment Management Agreement

Board Considerations Regarding Approval of Continuation of Investment Management Agreement

The Board of Trustees of First Trust Mortgage Income Fund (the “Fund”), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the “Agreement”) between the Fund and First Trust Advisors L.P. (the “Advisor”). The Board approved the continuation of the Agreement for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022. The Board determined that the continuation of the Agreement is in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.

To reach this determination, the Board considered its duties under the Investment Company Act of 1940, as amended (the “1940 Act”), as well as under the general principles of state law, in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 18, 2022 and June 12–13, 2022, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees, submitted on behalf of the Independent Trustees, that, among other things, outlined: the services provided by the Advisor to the Fund (including the relevant personnel responsible for these services and their experience); the advisory fee rate payable by the Fund as compared to fees charged to a peer group of funds (the “Expense Group”) and a broad peer universe of funds (the “Expense Universe”), each assembled by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent source, and as compared to fees charged to other clients of the Advisor; the expense ratio of the Fund as compared to expense ratios of the funds in the Fund’s Expense Group and Expense Universe; performance information for the Fund, including comparisons of the Fund’s performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the “Performance Universe”), each assembled by Broadridge; the nature of expenses incurred in providing services to the Fund and the

potential for the Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; any indirect benefits to the Advisor; and information on the Advisor’s compliance program. The Board reviewed initial materials with the Advisor at the meeting held on April 18, 2022, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, counsel to the Independent Trustees, on behalf of the Independent Trustees, requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and their counsel held prior to the June 12–13, 2022 meeting, as well as at the June meeting. The Board applied its business judgment to determine whether the arrangement between the Fund and the Advisor continues to be a reasonable business arrangement from the Fund’s perspective. The Board determined that, given the totality of the information provided with respect to the Agreement, the Board had received sufficient information to renew the Agreement. The Board considered that shareholders chose to invest or remain invested in the Fund knowing that the Advisor manages the Fund.

In reviewing the Agreement, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Fund and reviewed all of the services provided by the Advisor to the Fund, as well as the background and experience of the persons responsible for such services. The Board noted that the Advisor’s Securitized Products Group is responsible for the day-to-day management of the Fund’s investments. The Board considered the background and experience of the members of the Securitized Products Group and noted the Board’s prior meetings with members of the Group. The Board considered the Advisor’s statement that it applies the same oversight model internally with its Securitized Products Group as it uses for overseeing external sub-advisors, including portfolio risk monitoring and performance review. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor’s and the Fund’s compliance with the 1940 Act, as well as the Fund’s compliance with its investment objectives, policies and restrictions. The Board also considered a report from the Advisor with respect to its risk management functions related to the operation of the Fund. Finally, as part of the Board’s consideration of the Advisor’s services, the Advisor, in its written materials and at the April 18, 2022 meeting, described to the Board the scope of its ongoing investment in additional personnel and infrastructure to maintain and improve the quality of services provided to the Fund and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed the Fund consistent with its investment objectives, policies and restrictions.

The Board considered the advisory fee rate payable under the Agreement for the services provided. The Board received and reviewed information showing the fee rates and expense ratios of the peer funds in the Expense Group, as well as advisory and unitary fee rates charged by the Advisor to other fund and non-fund clients, as applicable. With respect to the Expense Group, the Board, at the April 18, 2022 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating a relevant peer group for the Fund, including that (i) the Fund is unique in its composition, which makes assembling peers with similar strategies and asset mix difficult; and (ii) certain peer fund assets are larger than those of the Fund, in which case the comparison causes the fixed expenses of the Fund to be larger on a percentage basis. The Board took these limitations into account in considering the peer data, and noted that the contractual advisory fee rate payable by the Fund, based on average net assets, was above the median contractual advisory fee of the peer funds in the Expense Group. With respect to fees charged to other clients, the Board considered differences between the Fund and other clients that limited their comparability. In considering the advisory fee rate overall, the Board also considered the Advisor’s statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor’s demonstrated long-term commitment to the Fund and the other funds in the First Trust Fund Complex.

The Board considered performance information for the Fund. The Board noted the process it has established for monitoring the Fund’s performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Fund. The Board determined that this process continues to be effective for reviewing the Fund’s performance. The Board received and reviewed information comparing the Fund’s performance for periods ended December 31, 2021 to the performance of the funds in the Performance Universe and to that of a benchmark index. In reviewing the Fund’s performance as compared to the performance of the Performance Universe, the Board took into account the limitations described above with respect to creating a relevant peer group for the Fund. Based on the information provided on net asset value performance, the Board noted that the Fund outperformed the Performance Universe median for the one-year period ended December 31, 2021 and underperformed the Performance Universe median for the three-, five- and ten-year periods ended December 31, 2021. The Board also noted that the Fund outperformed the benchmark index for the one-, five- and ten-year periods ended December 31, 2021 and underperformed the benchmark index for the three-year period ended December 31, 2021. The Board also received information on the Fund’s annual distribution rate as of December 31, 2021 and the Fund’s average trading discount for various periods and comparable information for a peer group.

On the basis of all the information provided on the fees, expenses and performance of the Fund, and the ongoing oversight by the Board, the Board concluded that the advisory fee continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to the Fund under the Agreement.

The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Fund and noted the Advisor’s statement that it believes that its expenses relating to providing advisory services to the Fund will likely increase during the next twelve months as the Advisor continues to build infrastructure and add new staff. The Board determined that due to the Fund’s closed-end structure, the potential for realization of economies of scale as Fund assets grow was not a material factor to be considered. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to the Fund for the twelve months ended December 31, 2021 and the estimated profitability level for the Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data, for the same period. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor’s profitability level for the Fund was not unreasonable. In addition, the Board considered indirect benefits described by the Advisor that may be realized from its relationship with the Fund, including the Advisor’s compensation for fund reporting services pursuant to a separate Fund Reporting Services Agreement. The Board also noted that the Advisor does not utilize soft dollars in connection with the Fund. The Board concluded that the character and amount of potential indirect benefits to the Advisor were not unreasonable.

Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreement continue to be fair and reasonable and that the continuation of the Agreement is in the best interests of the Fund. No single factor was determinative in the Board’s analysis.

First Trust Mortgage Income Fund (FMY)

October 31, 2022 (Unaudited)

Changes Occurring During the Prior Fiscal Year

The following information is a summary of certain changes during the most recent fiscal year ended October 31, 2022. This information may not reflect all of the changes that have occurred since you purchased shares of the Fund.

On October 24, 2022, the Board approved the adoption of a derivatives risk management program for the Fund pursuant to Rule 18f-4 under the 1940 Act covering the Fund’s use of derivatives and other transactions. Accordingly, the Fund’s use of certain derivatives, including options, futures contracts and options on futures contracts, will be subject to the program’s policies and procedures and the use of such derivatives may increase. Beginning on or around November 1, 2022, the Fund anticipates it could utilize futures contracts from time to time as a principal part of its investment strategy.

Investment Objectives

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.

Principal Investment Policies

In the pursuit of its investment objectives, under normal market conditions:

•	The Fund invests at least 80% of its managed assets in mortgage-backed securities. Such MBS may include those with fixed, floating or variable interest rates, those with interest rates that change based on multiples of changes in a specified index of interest rates and those with interest rates that change inversely to changes in interest rates, as well as those that do not bear interest. The Fund may also invest in MBS through TBA Transactions. The Fund does not invest in corporate bonds other than those primarily secured by interests in real estate.
•	The Fund may invest up to 35% of its managed assets in securities that, at the time of investment, are rated below investment grade (including securities that are unrated but judged to be of comparable quality by the Advisor).
•	The Fund may invest up to 20% of its managed assets in U.S. government securities, or cash or other short-term instruments, and may invest up to 10% of its managed assets in real-estate related assets collateralized by pools of assets, such as home equity loans and lines of credit, and asset-backed securities, including non-mortgage asset-backed securities.
•	The Fund may invest up to 10% of its managed assets in securities that, at the time of investment, are illiquid.

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.

The Fund may engage in the use of leverage by issuing preferred shares of beneficial interest, entering into reverse repurchase agreements, and/or issuing notes or other evidences of indebtedness including bank borrowings or commercial paper.

In addition, the Fund may, but is not required to, use various strategic transactions to: (1) seek to reduce interest rate risks arising from any use of leverage; (2) facilitate portfolio management; and (3) mitigate risks, including interest rate risk and credit risks. The Fund generally seeks to use these instruments and transactions as portfolio management or hedging techniques to protect against possible adverse changes in the market value of securities held in or to be purchased for the Fund’s portfolio, protect the value of the Fund’s portfolio, facilitate the sale of certain securities for investment purposes, manage the effective interest rate exposure of the Fund or establish positions in the derivative markets as a substitute for purchasing or selling particular securities.

Fundamental Policies

The Fund, as a fundamental policy, may not:

1. With respect to 75% of its total assets, purchase any securities if, as a result (i) more than 5% of the Fund’s total assets would then be invested in securities of any single issuer, or (ii) the Fund would hold more than 10% of the outstanding voting securities of any single issuer; provided, that government securities (as defined in the 1940 Act), securities issued by other investment companies and cash items (including receivables) shall not be counted for purposes of this limitation;

2. Purchase any security if, as a result of the purchase, 25% or more of the Fund’s total assets (taken at current value) would be invested in the securities of borrowers and other issuers having their principal business activities in the same industry; provided, that this limitation shall not apply with respect to issuers of mortgage-backed securities or obligations issued or guaranteed by the U.S. Government or by its agencies or instrumentalities;

3. Borrow money, except as permitted by the 1940 Act, the rules thereunder and interpretations thereof or pursuant to a Securities and Exchange Commission exemptive order;

Page 29

Table of Contents

Investment Objectives, Policies and Risks (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022 (Unaudited)

4. Issue senior securities, as defined in the 1940 Act, other than: (i) Preferred Shares which immediately after issuance will have asset coverage of at least 200%; (ii) indebtedness which immediately after issuance will have asset coverage of at least 300%; (iii) the borrowings permitted by investment restriction 3 set forth above; or (iv) pursuant to a Securities and Exchange Commission exemptive order;

5. Make loans of funds or other assets, other than by entering into repurchase agreements, lending portfolio securities and through the purchase of debt securities in accordance with its investment objectives, policies and limitations;

6. Act as underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 in connection with the purchase and sale of portfolio securities;

7. Purchase or sell real estate, but this shall not prevent the Fund from investing in securities of companies that deal in real estate or are engaged in the real estate business, including real estate investment trusts, and securities secured by real estate or interests therein and the Fund may hold and sell real estate or mortgages on real estate acquired through default, liquidation, or other distributions of an interest in real estate as a result of the Fund’s ownership of such securities; and

8. 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 or derivative instruments or from investing in securities or other instruments backed by physical commodities).

For the purpose of applying the limitation set forth in subparagraph 2 above, an issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the sole issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal bond is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal bond will be determined in accordance with the principles set forth above.

Except as noted above, the foregoing fundamental investment policies, together with the investment objectives of the Fund, cannot be changed without approval by holders of a majority of the outstanding voting securities of the Fund, as defined in the 1940 Act, which includes common shares of beneficial interest and preferred shares of beneficial interest (“Preferred Shares”), if any, voting together as a single class, and of the holders of the outstanding Preferred Shares voting as a single class. Under the 1940 Act a “majority of the outstanding voting securities” means the vote of: (A) 67% or more of the Fund’s shares present at a meeting, if the holders of more than 50% of the Fund’s shares are present or represented by proxy; or (B) more than 50% of the Fund’s shares, whichever is less.

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 or such credit rating agency’s ability to evaluate creditworthiness 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 or other obligated party of a debt security in the Fund’s portfolio will fail to pay dividends or interest and/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 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. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future.

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. Prepayment risk is the risk that the issuer of a debt security will repay principal prior to the scheduled maturity date. 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. The Fund may invest in securities that are restricted and/or illiquid securities. Restricted securities are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Restricted securities may be illiquid as they generally are not listed on an exchange and may have no active trading market. 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

Page 31

Table of Contents

Investment Objectives, Policies and Risks (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022 (Unaudited)

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. The Fund invests in securities that are subject to 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. As inflation increases, the present value of the Fund’s assets and distributions may decline. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund investors.

Interest Rate 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 (the “FCA”), which regulates LIBOR, intends to cease making LIBOR available as a reference rate over a phase-out period that began in early 2022. However, subsequent announcements by the FCA, the LIBOR administrators, and other regulators indicate that it is possible that the most widely used LIBOR rates may continue until mid-2023. While some instruments tied to LIBOR may include a replacement rate, not all instruments have such fallback provisions and the effectiveness of such replacement rates remains uncertain. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. In the United States, it is anticipated that in many instances the Secured Overnight Financing Rate (“SOFR”) will replace LIBOR as the reference rate for many floating rate instruments. There is no assurance that the composition or characteristics of SOFR, or any alternative reference rate, will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/ or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. 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. Yields on IOs and POs are very sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets.

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

Page 32

Investment Objectives, Policies and Risks (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022 (Unaudited)

common shares; and when the Fund uses certain types of leverage, the investment advisory fee payable to the 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. For example, the coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, had negative impacts, and in many cases severe impacts, on markets worldwide. While the development of vaccines has slowed the spread of the virus and allowed for the resumption of reasonably normal business activity in the United States, many countries continue to impose lockdown measures in an attempt to slow the spread. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. Also, in February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility across markets globally, including the United States. The hostilities and sanction resulting from those hostilities could have a significant impact on certain Fund investments as well as Fund performance. As the global pandemic and conflict in Ukraine have illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. These events also may adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on the Fund’s shares may widen.

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 such 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

Page 33

Table of Contents

Investment Objectives, Policies and Risks (Continued)

First Trust Mortgage Income Fund (FMY)

October 31, 2022 (Unaudited)

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.

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.

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.

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 securitized assets 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. 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.

As of the end of the period covered by the report, the registrant’s board of trustees has determined that Thomas R. Kadlec and Robert F. Keith are qualified to serve as audit committee financial experts serving on its audit committee and that each of them is “independent,” as defined by Item 3 of Form N-CSR.

Audit-Related Fees (Investment Advisor) -- The aggregate fees billed in each of the last two fiscal years for assurance and related services by the principal accountant that are reasonably related to the performance of the audit of the registrant’s financial statements and are not reported under paragraph (a) of this Item were $0 for the fiscal year ended October 31, 2021 and $0 for the fiscal year ended October 31, 2022.

Tax Fees (Investment Advisor) -- The aggregate fees billed in each of the last two fiscal years for professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning were $0 for the fiscal year ended October 31, 2021 and $0 for the fiscal year ended October 31, 2022.

All Other Fees (Investment Advisor) The aggregate fees billed in each of the last two fiscal years for products and services provided by the principal accountant to the registrant, other than the services reported in paragraphs (a) through (c) of this Item were $0 for the fiscal year ended October 31, 2021 and $0 for the fiscal year ended October 31, 2022.

Pursuant to its charter and its Audit and Non-Audit Services Pre-Approval Policy, the Audit Committee (the “Committee”) is responsible for the pre-approval of all audit services and permitted non-audit services (including the fees and terms thereof) to be performed for the registrant by its independent auditors. The Chairman of the Committee is authorized to give such pre-approvals on behalf of the Committee up to $25,000 and report any such pre-approval to the full Committee.

The Committee is also responsible for the pre-approval of the independent auditor’s engagements for non-audit services with the registrant’s advisor (not including a sub-advisor whose role is primarily portfolio management and is sub-contracted or overseen by another investment advisor) and any entity controlling, controlled by or under common control with the investment advisor that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant, subject to the de minimis exceptions for non-audit services described in Rule 2-01 of Regulation S-X. If the independent auditor has provided non-audit services to the registrant’s advisor (other than any sub-advisor whose role is primarily portfolio management and is sub-contracted with or overseen by another investment advisor) and any entity controlling, controlled by or under common control with the investment advisor that provides ongoing services to the registrant that were not pre-approved pursuant to its policies, the Committee will consider whether the provision of such non-audit services is compatible with the auditor’s independence.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

A description of the policies and procedures used to vote proxies on behalf of the Fund is attached as an exhibit.

The Securitized Products Group of First Trust Advisors L.P. is responsible for the day–to-day management of the registrant’s portfolio. The Securitized Products group has been led by James Snyder and Jeremiah Charles since 2013 and was previously known as the Mortgage Securities Team.

Jim Snyder. Mr. Snyder is a Senior Portfolio Manager and Co-head of the First Trust Securitized Products Group. He has over 32 years of investment and portfolio management experience. At First Trust, he is responsible for the management of the firm’s mortgage and securitized product fund offerings. Prior to joining First Trust in 2013, Jim spent most of his career leading several mortgage trading and portfolio management groups at American Express Financial Advisors, where he managed the AXP Federal Income Fund, and at Deerfield Capital, where he managed Deerfield’s Mortgage REIT and Opportunity Fund. Additionally, he has held senior positions at Fort Sheridan Advisors and Spyglass Capital. Mr. Snyder holds a B.S. and M.A. in Economics from DePaul University and an MBA from the University of Chicago Booth School of Business.

Jeremiah Charles. Mr. Charles is a Senior Portfolio Manager and Co-head of the First Trust Securitized Products Group. He has over 19 years of investment, trading and portfolio management experience. At First Trust, he is responsible for the management of the firm’s mortgage and securitized product fund offerings. Prior to joining First Trust in 2013, Jeremiah spent the majority of his career as a Senior Portfolio Manager at Deerfield Capital Management where he helped manage the Deerfield Mortgage REIT. In his career, he has also held positions at CRT Capital, where he worked as a Vice President in Securitized Products and at Piper Jaffray, where he began his career as an Analyst. Mr. Charles holds a B.S. in Finance from the Leeds School of Business at the University of Colorado, and a MS in Real Estate with honors from the Charles H. Kellstadt Graduate School of Business at DePaul University.

Potential conflicts of interest may arise when a portfolio manager of the registrant has day-to-day management responsibilities with respect to one or more other funds or other accounts. The First Trust Securitized Products Group adheres to its trade allocation policy utilizing a pro-rata methodology to address this conflict.

First Trust and its affiliate, First Trust Portfolios L.P. (“FTP”), have in place a joint Code of Ethics and Insider Trading Policies and Procedures that are designed to (a) prevent First Trust personnel from trading securities based upon material inside information in the possession of such personnel and (b) ensure that First Trust personnel avoid actual or potential conflicts of interest or abuse of their positions of trust and responsibility that could occur through such activities as front running securities trades for the registrant. Personnel are required to have duplicate confirmations and account statements delivered to First Trust and FTP compliance personnel who then compare such trades to trading activity to detect any potential conflict situations.

The compensation structure at First Trust is based on a fixed salary and discretionary bonus determined by First Trust management. Salaries are based on each individual’s position and overall value to First Trust. Bonuses are determined by First Trust management and are based on individual performance, the commitment to team performance and profitability, and the profitability of First Trust. Certain internal portfolio managers have an indirect ownership stake in the firm and will therefore receive their allocable share of ownership-related distributions.
