A couple of famous financial industry quotes came to mind recently as I was sizing up the current business climate: "There's no such thing as a free lunch" and "Don't fight the Fed!" It seems that for some, the trillions of dollars of financial stimulus funneled into U.S. households and businesses by the Federal government and its agencies to help mitigate the fallout stemming from the coronavirus ("COVID-19") pandemic, which commenced sometime around February 2020, was for all intents and purposes "free money." It was not free. From the close of February 2020 through March 2022, the Federal Reserve (the "Fed") expanded the U.S. money supply, known as M2, by 41% to $21.81 trillion to boost liquidity in the financial system. Normally, M2 grows around 6.0% on a year-over-year basis. When you factor in that all this new capital was accompanied by a breakdown of the global supply chain, there is little wonder why inflation is rampant. One of the more common definitions of inflation is too many dollars chasing too few goods. The biggest downside to the supply chain bottlenecks, such as the severe backup of container ships at some U.S. ports, is that they have markedly reduced the flow of imported goods to retailers. The Fed has been signaling to Americans and the rest of the globe that, after many years of artificially low interest rates, tighter monetary policy will likely rule the day for the foreseeable future. Higher interest rates make borrowing capital more expensive and that should slow consumption over time, which, in turn, should bring down inflation. Don't fight the Fed is code for don't bet against the Fed, in my opinion. Stay tuned! The primary job of the Fed is price stability. Its standard inflation target rate is 2.0%. The most recent Consumer Price Index release showed that prices were up 8.3% on a year-over-year basis as of April 30, 2022, according to data from the U.S. Bureau of Labor Statistics. While down from 8.5% the prior month, it is clearly elevated and that means the Fed has some work to do to with respect to mitigating inflation. The war between Russia and Ukraine is making the Fed's job even tougher, particularly in the areas of food and energy. Rising costs and potential shortages could become even bigger if the COVID-19 outbreak in China grows. These are important events to monitor. Fed Chairman Jerome Powell has stated that the Fed is poised to raise the Federal Funds target rate (upper bound) by 50 basis points at each of its next two meetings (set for June and July), which would take the rate up to 2.00%. Data from CME Group indicates that current market pricing has the rate rising to 2.75% or 3.00% by year-end. Securities markets do not go up in a straight line and they do not just go up year in and year out. In fact, what we have witnessed over the past couple of decades are often referred to as boom and bust cycles. Thankfully, it has ended up more boom than bust. Simply put, investors, not traders of the market, need to be willing to take the bad with the good. As the various stages of an economic cycle come and go (expansion to contraction), the markets tend to reprice securities to reflect the current narrative. In other words, we believe the markets essentially heal themselves - if you let them. That is an accurate depiction of how the markets have behaved so far in 2022, in my opinion. In response to a softening economy, the stock and bond markets have experienced some serious downside through the first four months of this year, as measured by the broader market indices. As of today, Brian Wesbury, Chief Economist at First Trust, is not forecasting a recession for the U.S. in 2022 or 2023. Whether he is proven right or wrong, we encourage investors to stay the course. Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Funds again in six months. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P.

The Fund's investment objective is to seek total return. The Fund will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") to be engaged in the energy infrastructure sector, which principally include publicly-traded master limited partnerships or limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, pipeline companies, utilities, and other companies that derive the majority of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). In addition, under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies headquartered or incorporated in the United States and Canada. ------------------------------------------------------------------------------------------------------------------------------------ PERFORMANCE ------------------------------------------------------------------------------------------------------------------------------------ AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended 5 Years Ended Inception (6/20/12) 5 Years Ended Inception (6/20/12) 4/30/22 4/30/22 4/30/22 to 4/30/22 4/30/22 to 4/30/22 FUND PERFORMANCE NAV 8.17% 14.76% 5.27% 6.87% 29.26% 92.53% Market Price 8.17% 14.80% 5.27% 6.88% 29.25% 92.65% INDEX PERFORMANCE Blended Benchmark(1) 10.88% 19.39% 7.38% 7.37% 42.75% 101.68% S&P 500(R) Index -9.65% 0.21% 13.66% 14.19% 89.68% 269.89% ------------------------------------------------------------------------------------------------------------------------------------ (See Notes to Fund Performance Overview on page 6.) ----------------------------- (1) The Blended Benchmark consists of the following two indices: 50% of the PHLX Utility Sector Index which is a market capitalization weighted index composed of geographically diverse public U.S. utility stocks; and 50% of the Alerian MLP Total Return Index which is a float-adjusted, capitalization weighted composite of the 50 most prominent energy Master Limited Partnerships (MLPs). Indices are unmanaged and an investor cannot invest directly in an index. All index returns assume that distributions are reinvested when they are received. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS Information showing the number of days the market price of the Fund's shares was greater (at a premium) and less (at a discount) than the Fund's net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter) is available at https://www.ftportfolios.com/Retail/etf/home.aspx. Page 5 -------------------------------------------------------------------------------- NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- Total returns for the periods since inception are calculated from the inception date of each Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the periods indicated. "Cumulative Total Returns" represent the total change in value of an investment over the periods indicated. Each Fund's per share net asset value ("NAV") is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return ("Market Price") is determined by using the midpoint of the national best bid and offer price ("NBBO") as of the time that the Fund's NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund's NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund's NAV was calculated. Since shares of each Fund did not trade in the secondary market until after the Fund's inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of each Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in each Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund's past performance is no guarantee of future performance.

Page 7 FIRST TRUST EXCHANGE-TRADED FUND IV UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2022 (UNAUDITED) As a shareholder of First Trust North American Energy Infrastructure Fund or First Trust EIP Carbon Impact ETF (each a "Fund" and collectively, the "Funds"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended April 30, 2022. ACTUAL EXPENSES The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Six-Month Period" to estimate the expenses you paid on your account during this six-month period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. ------------------------------------------------------------------------------------------------------------------------------ ANNUALIZED EXPENSE RATIO EXPENSES PAID BEGINNING ENDING BASED ON THE DURING THE ACCOUNT VALUE ACCOUNT VALUE SIX-MONTH SIX-MONTH NOVEMBER 1, 2021 APRIL 30, 2022 PERIOD PERIOD (a) ------------------------------------------------------------------------------------------------------------------------------ FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) Actual $1,000.00 $1,081.70 0.95% $4.90 Hypothetical (5% return before expenses) $1,000.00 $1,020.08 0.95% $4.76 FIRST TRUST EIP CARBON IMPACT ETF (ECLN) Actual $1,000.00 $1,047.70 0.95% $4.82 Hypothetical (5% return before expenses) $1,000.00 $1,020.08 0.95% $4.76 (a) Expenses are equal to the annualized expense ratio as indicated in the table multiplied by the average account value over the period (November 1, 2021 through April 30, 2022), multiplied by 181/365 (to reflect the six-month period).

ORGANIZATION First Trust Exchange-Traded Fund IV (the "Trust") is an open-end management investment company organized as a Massachusetts business trust on September 15, 2010, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the "1940 Act"). The Trust currently consists of eleven funds that are offering shares. This report covers the two funds (each a "Fund" and collectively, the "Funds") listed below. The shares of each Fund are listed and traded on the NYSE Arca, Inc. ("NYSE Arca"). First Trust North American Energy Infrastructure Fund -- (ticker "EMLP") First Trust EIP Carbon Impact ETF -- (ticker "ECLN") Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large blocks of shares known as "Creation Units." Each Fund is an actively managed exchange-traded fund. EMLP's investment objective is to seek total return. EMLP will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") to be engaged in the energy infrastructure sector, which principally include publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, pipeline companies, utilities, and other companies that derive the majority of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). In addition, under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies headquartered or incorporated in the United States and Canada. ECLN's investment objective is to seek to achieve a competitive risk-adjusted total return balanced between dividends and capital appreciation. ECLN will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in equity securities of companies identified by EIP as having or seeking to have a positive carbon impact, defined as companies that reduce, have a publicly available plan to reduce, or enable the reduction of carbon and other greenhouse gas emissions from the production, transportation, conversion, storage and use of energy. ECLN's investments will be concentrated in the industries constituting the energy infrastructure sector, which principally include utilities, natural gas pipeline companies, manufacturers, contracted developers and/or owners of renewable energy, and other companies that derive the majority of their earnings from manufacturing, operating or providing services in support of infrastructure assets and/or infrastructure activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. 2. SIGNIFICANT ACCOUNTING POLICIES The Funds are each considered an investment company and follow 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 Funds 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 Each Fund's NAV is determined daily as of the close of regular trading on the New York Stock Exchange ("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. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund's NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding. Each Fund's investments are valued daily at market value or, in the absence of the market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds' investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), Page 17 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) in accordance with valuation procedures adopted by the Trust's Board of Trustees, and in accordance with provisions of the 1940 Act. Investments valued by the Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund's investments are valued as follows: Common stocks, MLPs and other equity securities listed on any national or foreign exchange (excluding The Nasdaq Stock Market LLC ("Nasdaq") and the London Stock Exchange Alternative Investment Market ("AIM")) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the principal market for such securities. Securities trading on foreign exchanges or over-the-counter markets that close prior to the NYSE close may be valued using a systematic fair valuation model provided by a third-party pricing service. If these foreign securities meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of the foreign markets. Shares of open-end funds are valued at fair value which is based on NAV per share. Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust's Board of Trustees or its delegate, the Advisor's Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) 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 a 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 type of security; 2) the size of the holding; 3) the initial cost of the security; 4) transactions in comparable securities; 5) price quotes from dealers and/or third-party pricing services; 6) relationships among various securities; 7) information obtained by contacting the issuer, analysts, or the appropriate stock exchange; 8) an analysis of the issuer's financial statements; and 9) the existence of merger proposals or tender offers that might affect the value of the security. If the securities in question are foreign securities, the following additional information may be considered: 1) the value of similar foreign securities traded on other foreign markets; 2) ADR trading of similar securities; 3) closed-end fund or exchange-traded fund trading of similar securities; 4) foreign currency exchange activity; 5) the trading prices of financial products that are tied to baskets of foreign securities; 6) factors relating to the event that precipitated the pricing problem; 7) whether the event is likely to recur; and 8) whether the effects of the event are isolated or whether they affect entire markets, countries or regions. Because foreign markets may be open on different days than the days during which investors may transact in the shares of a Fund, the value of the Fund's securities may change on the days when investors are not able to transact in the shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars using exchange rates determined daily as of the close of regular trading on the NYSE. Page 18 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) The Funds are 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: o 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. o 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. o 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 each Fund's investments as of April 30, 2022, is included with each Fund's Portfolio of Investments. 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. Dividend income is recorded on the ex-dividend date. Interest income, if any, is recorded on the accrual basis. Distributions received from a Fund's investments in MLPs generally are comprised of return of capital and investment income. A Fund records estimated return of capital and investment income based on historical information available from each MLP. These estimates may subsequently be revised based on information received from the MLPs after their tax reporting periods are concluded. Distributions received from a Fund's investments in Real Estate Investment Trusts ("REITs") may be comprised of return of capital, capital gains, and income. The actual character of the amounts received during the year are not known until after the REITs' fiscal year end. A Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by a Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude. C. FOREIGN CURRENCY The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of investments and items of income and expense are translated on the respective dates of such transactions. Unrealized gains and losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in "Net change in unrealized appreciation (depreciation) on foreign currency translation" on the Statements of Operations. Unrealized gains and losses on investments in securities which result from changes in foreign exchange rates are included with fluctuations arising from changes in market price and are shown in "Net change in unrealized appreciation (depreciation) on investments" on the Statements of Operations. Net realized foreign currency gains and losses include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received and is included in "Net realized gain (loss) on foreign currency transactions" on the Statements of Operations. The portion of foreign currency gains and losses related to fluctuations in exchange rates between the initial purchase settlement date and subsequent sale trade date is included in "Net realized gain (loss) on investments" on the Statements of Operations. D. DIVIDENDS AND DISTRIBUTION TO SHAREHOLDERS Dividends from net investment income of each Fund, if any, are declared and paid quarterly, or as the Board of Trustees may determine from time to time. Distributions of net realized gains earned by each Fund, if any, are distributed at least annually. 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 Page 19 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) treatment of income and gain/loss on significantly modified portfolio securities held by the Funds 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 time in the future. The tax character of distributions paid by each Fund during the fiscal year ended October 31, 2021 was as follows: Distributions Distributions Distributions paid from paid from paid from Ordinary Income Capital Gains Return of Capital --------------- ------------- ----------------- First Trust North American Energy Infrastructure Fund $ 71,059,859 $ -- $ -- First Trust EIP Carbon Impact ETF 173,970 -- -- As of October 31, 2021, the components of distributable earnings on a tax basis for each Fund were as follows: Accumulated Undistributed Capital and Net Unrealized Ordinary Other Appreciation Income Gain (Loss) (Depreciation) --------------- ------------- ----------------- First Trust North American Energy Infrastructure Fund $ (42,502,994) $(430,769,976) $ 411,924,322 First Trust EIP Carbon Impact ETF 18,341 (42,033) 1,368,556 E. INCOME TAXES Each 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, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund's taxable income exceeds the distributions from such taxable income for the calendar year. Each 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. Each 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, 2021, EMLP and ECLN had non-expiring capital loss carryforwards available for federal income tax purposes of $430,769,976 and $42,033, respectively. The Funds are 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. For EMLP, the taxable years ended 2018, 2019, 2020, and 2021 remain open to federal and state audit. For ECLN, the taxable years ended 2019, 2020, and 2021 remain open to federal and state audit. As of April 30, 2022, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds' financial statements for uncertain tax positions. During the taxable year ended October 31, 2021, the following Fund utilized non-expiring capital loss carryforwards in the following amount: Capital Loss Carryforward Utilized --------------- First Trust North American Energy Infrastructure Fund $ 23,621,213 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, 2021, the following Fund incurred and elected to defer late year ordinary or capital losses as follows: Qualified Late Year Losses ---------------------------------- Ordinary Losses Capital Losses --------------- -------------- First Trust North American Energy Infrastructure Fund $ 42,502,994 $ -- Page 20 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) As of April 30, 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: Gross Gross Net Unrealized Unrealized Unrealized Appreciation Tax Cost Appreciation (Depreciation) (Depreciation) --------------- --------------- --------------- --------------- First Trust North American Energy Infrastructure Fund $ 1,884,599,472 $ 563,712,274 $ (13,655,862) $ 550,056,412 First Trust EIP Carbon Impact ETF 17,054,895 2,117,313 (301,413) 1,815,900 F. EXPENSES Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 3). 3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS First Trust, the investment advisor to the Funds, 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 ongoing monitoring of the securities in each Fund's portfolio, managing the Funds' business affairs and providing certain administrative services necessary for the management of the Funds. The Trust, on behalf of the Funds, and First Trust have retained EIP, an affiliate of First Trust, to serve as the Funds' investment sub-advisor. In this capacity, EIP is responsible for the selection and ongoing monitoring of the securities in each Fund's investment portfolio. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise EIP and its management of the investment of each Fund's assets and will pay EIP for its services as the Funds' sub-advisor. First Trust will also be responsible for each Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. Each Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. EIP receives a sub-advisory fee for EMLP from First Trust equal to 45% of any remaining monthly investment management fee paid to First Trust after the Fund's average Fund expenses accrued during the most recent twelve months are subtracted from the investment management fee in a given month. EIP receives a sub-advisory fee for ECLN from First Trust equal to an annual rate of 0.475% of the Fund's average daily net assets less one-half of the Fund's expenses, for which EIP is responsible. First Trust Capital Partners, LLC ("FTCP"), an affiliate of First Trust, owns, through a wholly-owned subsidiary, a 15% ownership interest in each of EIP and EIP Partners, LLC, an affiliate of EIP. The Trust has multiple service agreements with The Bank of New York Mellon ("BNYM"). Under the service agreements, BNYM performs custodial, fund accounting, certain administrative services, and transfer agency services for each Fund. As custodian, BNYM is responsible for custody of each Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of each Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for each Fund. BNYM is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company. Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates ("Independent Trustees") is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a defined-outcome fund or an index fund. Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities.

PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2022, the cost of purchases and proceeds from sales of investments for each Fund, excluding short-term investments and in-kind transactions, were as follows: Purchases Sales --------------- --------------- First Trust North American Energy Infrastructure Fund $ 375,700,091 $ 485,603,829 First Trust EIP Carbon Impact ETF 2,608,494 4,236,440 For the six months ended April 30, 2022, the cost of in-kind purchases and proceeds from in-kind sales for each Fund were as follows: Purchases Sales --------------- --------------- First Trust North American Energy Infrastructure Fund $ 203,288,860 $ 47,916,350 First Trust EIP Carbon Impact ETF -- 2,285,344 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as "Authorized Participants" have contractual arrangements with a Fund or one of the Fund's service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as "Creation Units." Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation ("NSCC") the "basket" of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund's shares. An Authorized Participant that wishes to effectuate a creation of a Fund's shares deposits with the Fund the "basket" of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund's shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold a Fund's shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund's shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund's shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund's shares at or close to the NAV per share of the Fund. Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket. Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed. 6. DISTRIBUTION PLAN The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are authorized to pay an amount up to 0.25% of their average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Funds, for amounts expended to finance activities primarily intended to result Page 22 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services. No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2023. 7. INDEMNIFICATION The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust's maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 8. SUBSEQUENT EVENTS Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed. Page 23 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to its portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund's website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov.

Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC's website at www.sec.gov. Each Fund's complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund's Forms N-PORT and Forms N-CSR are available on the SEC's website listed above. RISK CONSIDERATIONS RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND. CONCENTRATION RISK. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund's investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund's corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified. CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer's ability to make such payments. CYBER SECURITY RISK. The funds are 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 a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a 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 a fund to many of the same risks associated with direct cyber security breaches. DEFINED OUTCOME FUNDS RISK. To the extent a fund's investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor's investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund's share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless. Page 24 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) DERIVATIVES RISK. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund's portfolio managers use derivatives to enhance the fund's return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund. EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the value of the fund's shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. ETF RISK. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF's shares, or decisions by an ETF's authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF's shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads. FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund's fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund's fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities. INDEX OR MODEL CONSTITUENT RISK. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund's net asset value could be negatively impacted and the fund's market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund's shares. INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund's costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders. INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund's investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.

To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate ("LIBOR") as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom's Financial Conduct Authority, which regulates LIBOR, has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate ("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. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund. MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund's investment portfolio, the fund's portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective. MARKET RISK. Securities held by a fund, as well as shares of a 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 a 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 a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. 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. NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries. OPERATIONAL RISK. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each 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 a fund's ability to meet its investment objective. Although the funds and the funds' investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE Page 26 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2022 (UNAUDITED) LIQUIDITY RISK MANAGEMENT PROGRAM In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the "1940 Act"), the Funds and each other fund in the First Trust Fund Complex, other than the closed-end funds, have adopted and implemented a liquidity risk management program (the "Program") reasonably designed to assess and manage the funds' liquidity risk, i.e., the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors' interests in the fund. The Board of Trustees of the First Trust Funds has appointed First Trust Advisors L.P. (the "Advisor") as the person designated to administer the Program, and in this capacity the Advisor performs its duties primarily through the activities and efforts of the First Trust Liquidity Committee (the "Liquidity Committee"). Pursuant to the Program, the Liquidity Committee classifies the liquidity of each fund's portfolio investments into one of the four liquidity categories specified by Rule 22e-4: highly liquid investments, moderately liquid investments, less liquid investments and illiquid investments. The Liquidity Committee determines certain of the inputs for this classification process, including reasonably anticipated trade sizes and significant investor dilution thresholds. The Liquidity Committee also determines and periodically reviews a highly liquid investment minimum for certain funds, monitors the funds' holdings of assets classified as illiquid investments to seek to ensure they do not exceed 15% of a fund's net assets and establishes policies and procedures regarding redemptions in kind. At the April 18, 2022 meeting of the Board of Trustees, as required by Rule 22e-4 and the Program, the Advisor provided the Board with a written report prepared by the Advisor that addressed the operation of the Program during the period from March 16, 2021 through the Liquidity Committee's annual meeting held on March 17, 2022 and assessed the Program's adequacy and effectiveness of implementation during this period, including the operation of the highly liquid investment minimum for each fund that is required under the Program to have one, and any material changes to the Program. Note that because the Funds primarily hold assets that are highly liquid investments, the Funds have not adopted any highly liquid investment minimums. As stated in the written report, during the review period, no fund breached the 15% limitation on illiquid investments, no fund with a highly liquid investment minimum breached that minimum and no fund filed a Form N-LIQUID. The Advisor concluded that each fund's investment strategy is appropriate for an open-end fund; that the Program operated effectively in all material respects during the review period; and that the Program is reasonably designed to assess and manage the liquidity risk of each fund and to maintain compliance with Rule 22e-4.
