Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as "anticipate," "estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or other words that convey uncertainty of future events or outcomes. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the series of First Trust Exchange-Traded Fund IV (the "Trust") described in this report (First Trust North American Energy Infrastructure Fund; hereinafter referred to as the "Fund") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

PERFORMANCE AND RISK DISCLOSURE There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in the Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of other risks of investing in the Fund. Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit http://www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost. The Advisor may also periodically provide additional information on Fund performance on the Fund's webpage at http://www.ftportfolios.com. HOW TO READ THIS REPORT This report contains information that may help you evaluate your investment in the Fund. It includes details about the Fund's portfolio and presents data and analysis that provide insight into the Fund's performance and investment approach. The statistical information that follows may help you understand the Fund's performance compared to that of relevant market benchmarks. It is important to keep in mind that the opinions expressed by personnel of the Advisor and/or Sub-Advisor are just that: informed opinions. They should not be considered to be promises or advice.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices, and second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) The investment objective of the First Trust North American Energy Infrastructure Fund (the "Fund") is to seek total return. The Fund pursues its objective by investing at least 80% of its net assets under normal market conditions (plus the amount of any borrowing for investment purposes) in equity securities of companies engaged in the energy infrastructure sector. These companies principally include publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, Canadian Income Equities, pipeline companies, utilities and other companies that derive at least 50% of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). The Fund will be generally concentrated in Energy Infrastructure Companies. Under normal market conditions, the Fund will invest at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in equity securities of companies headquartered or incorporated in the United States and Canada. There can be no assurance that the Fund's investment objective will be achieved. The Fund may not be appropriate for all investors. ---------------------------------------------------------------------------------------------------------------- PERFORMANCE ---------------------------------------------------------------------------------------------------------------- AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (6/20/12) Inception (6/20/12) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 1.65% -13.34% 7.04% 30.04% Market Price 1.56% -13.29% 7.06% 30.14% INDEX PERFORMANCE Blended Benchmark(1) 4.09% -9.21% 5.97% 25.10% S&P 500(R) Index 0.43% 1.21% 13.92% 65.37% ---------------------------------------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the 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 the 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 the Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance. ----------------------------- (1) The Blended Benchmark consists of the following two indices: 50% of the Philadelphia Stock Exchange Utility 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.

MURCHIE EVA PAO PORTFOLIO MANAGER CO-PORTFOLIO MANAGER FOUNDER AND CEO OF ENERGY PRINCIPAL OF ENERGY INCOME PARTNERS, LLC INCOME PARTNERS, LLC JOHN TYSSELAND CO-PORTFOLIO MANAGER PRINCIPAL OF ENERGY INCOME PARTNERS, LLC Page 4 -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) -------------------------------------------------------------------------------- UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust North American Energy Infrastructure Fund (the "Fund"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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, 2015 APRIL 30, 2016 PERIOD PERIOD (a) ----------------------------------------------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) Actual $1,000.00 $1,016.50 0.95% $4.76 Hypothetical (5% return before expenses) $1,000.00 $1,020.14 0.95% $4.77 (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, 2015 through April 30, 2016), multiplied by 182/366 (to reflect the one-half year period).

See Notes to Financial Statements Page 11 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust North American Energy Infrastructure Fund (the "Fund"), which trades under the ticker "EMLP" on the NYSE Arca, Inc. ("NYSE Arca"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are issued and redeemed principally in-kind for securities in which the Fund invests or for cash or, in certain circumstances, a combination of both. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to seek total return. The Fund invests in energy infrastructure companies which principally include publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, Canadian Income Equities, pipeline companies, utilities, and other companies that derive at least 50% 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"). 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. The Fund's NAV is calculated 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 shares outstanding. The 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 Fund's investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), 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. The 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 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. Page 12 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) 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 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 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 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 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 the 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. 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: 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. Page 13 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund's investments as of April 30, 2016, is included with the 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 the Fund's investments in MLPs generally are comprised of return of capital and investment income. The 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. C. FOREIGN CURRENCY The books and records of the Fund 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 Statement 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 Statement 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 are shown in "Net realized gain (loss) on foreign currency transactions" on the Statement 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 Statement of Operations. D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income of the 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 the Fund, if any, are distributed at least annually. Distributions from net investment income and realized capital gains are determined in accordance with 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 significantly modified 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 time in the future. The tax character of distributions paid during the fiscal year ended October 31, 2015 was as follows: Distributions paid from: Ordinary income................................. $ 36,418,951 Capital gain.................................... -- Return of capital............................... -- As of October 31, 2015, the components of distributable earnings on a tax basis for the Fund were as follows: Undistributed ordinary income................... $ -- Accumulated capital and other gain (loss)....... (20,930,851) Net unrealized appreciation (depreciation)...... (94,526,075) Page 14 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) E. 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, 2015, the Fund had non-expiring capital loss carryforwards available for federal income tax purposes of $20,930,851. 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, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2012, 2013, 2014 and 2015 remain open to federal and state audit. As of April 30, 2016, 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. 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 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 ongoing monitoring of the securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. The Fund and First Trust have retained Energy Income Partners, LLC ("EIP" or the "Sub-Advisor"), an affiliate of First Trust, to serve as its investment sub-advisor. In this capacity, EIP is responsible for the selection and on-going monitoring of the securities in the 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 the Fund's assets and will pay EIP for its services as the Fund's sub-advisor. First Trust will also be responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The 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 from First Trust equal to 45% of any remaining monthly investment management fee paid to First Trust after the average Fund expenses accrued during the most recent twelve months are subtracted from the investment management fee in a given month. 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the Fund. BNYM is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company. Page 15 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or actively managed fund, or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2016, the cost of purchases and proceeds from sales of investments, excluding short-term investments and in-kind transactions, were $204,901,923 and $203,142,462 respectively. For the six months ended April 30, 2016, the cost of in-kind purchases and proceeds from in-kind sales were $211,110,053 and $58,412,405, respectively. 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of equity securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a standard redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services. Page 16 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 7. INDEMNIFICATION The Trust, on behalf of the Fund, 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.

YOU SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV. The following summarizes some of the risks that should be considered for the Fund. CONCENTRATION RISK. A fund concentrated in a single industry or sector is likely to present more risks than a fund that is broadly diversified over several industries or sectors. Compared to the broad market, an individual industry or sector may be more strongly affected by changes in the economic climate, broad market shifts, moves in a particular dominant stock, or regulatory changes. DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. EQUITY SECURITIES RISK. Because the Fund invests in equity securities, the value of the Fund's shares will fluctuate with changes in the value of these 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 the capital rises and borrowing costs increase. SMALLER COMPANIES RISK. The Fund invests in small and/or mid capitalization companies. Such companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. MARKET RISK. Market risk is the risk that a particular security owned by the Fund, Shares of the Fund or securities in general may fall in value. Shares are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall securities values could decline generally or could underperform other investments. Page 18 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP) APRIL 30, 2016 (UNAUDITED) NON-DIVERSIFICATION RISK. Because the Fund is non-diversified, it may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issues. ENERGY INFRASTRUCTURE COMPANIES RISK. The Fund invests in Energy Infrastructure Companies and is subject to certain risks inherent in investing in these types of securities. Energy Infrastructure Companies may be directly affected by energy commodity prices, especially those Energy Infrastructure Companies which own the underlying energy commodity. A decrease in the production or availability of natural gas, natural gas liquids ("NGLs"), crude oil, coal or other energy commodities or a decrease in the volume of such commodities available for transportation, processing, storage or distribution may adversely impact the financial performance of Energy Infrastructure Companies. Energy Infrastructure Companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of Energy Infrastructure Companies. Natural disasters, such as hurricanes in the Gulf of Mexico, also may impact Energy Infrastructure Companies. Certain Energy Infrastructure Companies are subject to the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations, and the capital market's ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for these companies. Such issuers have been experiencing certain of these problems to varying degrees. MLP RISK. An investment in MLP units involves risks which differ from an investment in common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership. In addition, there are certain tax risks associated with an investment in MLP units and conflicts of interest exist between common unit holders and the general partner, including those arising from incentive distribution payments. In addition, there is the risk that a MLP could be, contrary to its intention, taxed as a corporation, resulting in decreased returns from such MLP. GEOGRAPHIC RISK. The Fund invests primarily in securities of companies headquartered or incorporated in the United States and Canada. An investment in a particular geographic region may be particularly susceptible to changes in the political, diplomatic and economic conditions of that region or any new regulatory requirements of the region. Accordingly, an investment in the Fund may be more volatile than an investment diversified across several geographic regions. NON-U.S. SECURITIES. The Fund invests in securities of non-U.S. issuers, including non-U.S. dollar-denominated securities traded in Canada or other foreign countries and U.S. dollar-denominated securities of non-U.S. issuers traded in the United States. Such 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; lack of liquidity; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. These risks may be heightened for securities of companies located in, or with significant operations in, emerging market countries. CURRENCY RISK. Because the Fund's NAV is determined on the basis of U.S. dollars and the Fund invests in foreign securities, you may lose money if the local currency of a foreign market depreciates against the U.S. dollar, even if the local currency value of the Fund's holdings goes up. INTEREST RATE RISK. Rising interest rates could adversely impact the financial performance of MLPs, MLP-related entities and energy companies. Rising interest rates may increase an MLP's, MLP-related entity's or energy company's cost of capital, which would increase operating costs and may reduce an MLP's, MLP-related entity's or energy company's ability to execute acquisitions or expansion projects in a cost-effective manner. Rising interest rates may also impact the price of MLP units, MLP-related entity securities and energy company shares as the yields on alternative investments increase. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, Energy Income Partners will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objective. Page 19 This page intentionally left blank.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) The First Trust Senior Loan Fund's (the "Fund") primary investment objective is to provide high current income. The Fund's secondary investment objective is the preservation of capital. The Fund pursues its objectives by investing at least 80% of its net assets (plus the amount of any borrowing for investment purposes) under normal market conditions in a diversified portfolio of first lien senior floating rate loan interests ("Senior Loans"). A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions to one or more corporations, partnerships or other business entities and typically pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate, most commonly the London Interbank Offered Rate ("LIBOR"). A Senior Loan is considered senior to all other unsecured claims against the borrower, senior to or equal with all other secured claims; this means that in the event of a bankruptcy, the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing unsecured claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence. The Fund invests primarily in Senior Loans that are below investment grade quality at the time of investment. Securities rated below investment grade, commonly referred to as "junk" or "high-yield" securities, include securities that are rated Ba1/BB+/BB+ or below by Moody's Investors Service, Inc., Fitch, Inc., or Standard & Poor's Ratings Group, respectively. The Fund invests in Senior Loans made predominantly to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. The Senior Loans included in the Fund's portfolio often maintain an average interest rate duration of less than 90 days; however, the inclusion of LIBOR floors on certain Senior Loans or other factors may cause interest rate duration to be longer than 90 days. The Fund may also invest up to 20% of its net assets in (1) non-Senior Loan debt securities, which may be fixed-rate or floating-rate income-producing securities (including, without limitation, U.S. government debt securities and corporate debt securities), (2) warrants and equity securities issued by a borrower or its affiliates, and/or (3) securities of other investment companies. ------------------------------------------------------------------------------------------------------------------------- PERFORMANCE ------------------------------------------------------------------------------------------------------------------------- AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (5/1/13) Inception (5/1/13) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 1.86% 1.17% 2.49% 7.64% Market Price 1.61% 1.29% 2.50% 7.68% INDEX PERFORMANCE Markit iBoxx USD Liquid Leveraged Loan Index 1.98% -1.04% 1.59% 4.84% S&P/LSTA Leveraged Loan 100 Index 2.52% -0.59% 1.73% 5.27% ------------------------------------------------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the 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 the 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 the Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance.

The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.

PORTFOLIO MANAGEMENT TEAM WILLIAM HOUSEY, CFA - SENIOR VICE PRESIDENT, SENIOR PORTFOLIO MANAGER SCOTT D. FRIES, CFA - SENIOR VICE PRESIDENT, PORTFOLIO MANAGER Page 5 FIRST TRUST SENIOR LOAN FUND (FTSL) UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust Senior Loan Fund (the "Fund"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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.

These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more United States banks or (iii) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR floor that establishes a minimum LIBOR rate. The interest rate shown reflects the rate in effect at April 30, 2016. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche at varying rates. (b) Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown. (c) Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be illiquid by the investment advisor, First Trust Advisors L.P. (the "Advisor"). (d) This security is fair valued by the Advisor's Pricing Committee in accordance with procedures adopted by the Trust's Board of Trustees, and in accordance with provisions of the Investment Company Act of 1940, as amended. At April 30, 2016, securities noted as such amounted to $619,293 or 0.1% of net assets. (e) This issuer has filed for protection in federal bankruptcy court. (f) This issuer is in default but interest is still being accrued by the Fund and paid by the issuer. Page 16 See Notes to Financial Statements FIRST TRUST SENIOR LOAN FUND (FTSL) PORTFOLIO OF INVESTMENTS (CONTINUED) APRIL 30, 2016 (UNAUDITED) (g) On December 21, 2015, Millennium Health, LLC completed a Bankruptcy Plan of Reorganization. As part of the Bankruptcy Plan of Reorganization, the holders of Millennium Laboratories LLC, Tranche B Term Loan received a portion of a new term loan and a pro rata share of the newly issued common equity shares in New Millennium Holdco, Inc., the new company. Each lender was also issued a beneficial interest in the Corporate Claim Trust entitling it, as holder of such beneficial interest, to receive Corporate Claim Trust Distributions when and if net cash proceeds from the pursuit of Retained Corporate Causes of Action are available to make such a distribution. In addition, each lender was issued a beneficial interest in the Lender Claim Trust entitling it, as holder of such beneficial interest, to receive Lender Claim Trust Distributions when and if net cash proceeds from the pursuit of Retained Lender Causes of Action are available to make such a distribution. (h) Delayed Draw Loan (See Note 2C - Unfunded Loan Commitments in the Notes to Financial Statements). (i) Represents commitment fee rate on Unfunded Loan Commitment. (j) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended, and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be liquid by the Advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. At April 30, 2016, securities noted as such amounted to $10,709,273 or 2.4% of net assets. (k) These notes are Payment-in-Kind ("PIK") Notes whereby the issuer may, at its option, elect to pay interest on the notes (1) entirely in cash or (2) entirely in PIK Interest. Interest paid in cash will accrue at the rate of 7.000% per annum ("Cash Interest Rate") and PIK Interest will accrue on the Notes at a rate per annum equal to the Cash Interest Rate plus 75 basis points. For the six months ended April 30, 2016, this security paid all of its interest in cash. (l) Non-income producing security. (m) Interest rate shown reflects yield as of April 30, 2016. (n) Aggregate cost for financial reporting purposes, which approximates the aggregate cost for federal income tax purposes. As of April 30, 2016, the aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $2,235,483 and the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $8,265,860. ----------------------------- VALUATION INPUTS A summary of the inputs used to value the Fund's investments as of April 30, 2016 is as follows (see Note 2A - Portfolio Valuation in the Notes to Financial Statements): LEVEL 2 LEVEL 3 TOTAL LEVEL 1 SIGNIFICANT SIGNIFICANT VALUE AT QUOTED OBSERVABLE UNOBSERVABLE 4/30/2016 PRICES INPUTS INPUTS -------------- -------------- -------------- -------------- Senior Floating-Rate Loan Interests: Cable & Satellite.............................. $ 619,293 $ -- $ -- $ 619,293 Property & Casualty Insurance.................. 270,829 -- -- 270,829 Other Industry Categories*..................... 381,367,921 -- 381,367,921 -- -------------- -------------- -------------- -------------- Total Senior Floating-Rate Loan Interests......... 382,258,043 -- 381,367,921 890,122 Corporate Bonds*.................................. 35,531,190 -- 35,531,190 -- Foreign Corporate Bonds*.......................... 4,393,183 -- 4,393,183 -- Common Stocks*.................................... 90,848 -- 90,848 -- Rights*........................................... --** -- -- --** Money Market Funds................................ 37,191,009 37,191,009 -- -- -------------- -------------- -------------- -------------- Total Investments................................. $ 459,464,273 $ 37,191,009 $ 421,383,142 $ 890,122 ============== ============== ============== ============== * See Portfolio of Investments for industry breakout.

Level 3 Senior Floating-Rate Loan Interests are valued based on either third-party pricing service prices obtained from dealer runs and indicative sheets from brokers or are valued using broker quotes. The values are based on unobservable and non-quantitative inputs. The Trust's Board of Trustees has adopted valuation procedures that are utilized by the Advisor's Pricing Committee to oversee the day-to-day valuation of the Fund's investments. The Advisor's Pricing Committee, through the Fund's fund accounting agent, monitors the daily pricing via tolerance checks and stale and unchanged price reviews. The Advisor's Pricing Committee also reviews monthly back testing of pricing service prices by comparing sales prices of the Fund's investments to prior day pricing service prices. Additionally, the Advisor's Pricing Committee reviews periodic information from the Fund's third-party pricing service that compares secondary market trade prices to their daily valuations. The following table presents the activity of the Fund's investments measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the period presented: BEGINNING BALANCE AT OCTOBER 31, 2015 Senior Floating-Rate Loan Interests $ 1,413,777 Rights -- Net Realized Gain (Loss) Senior Floating-Rate Loan Interests 1,889 Rights -- Change in Unrealized Appreciation /(Depreciation) Senior Floating-Rate Loan Interests (16,293) Rights -- Purchases Senior Floating-Rate Loan Interests -- Rights --* Sales Senior Floating-Rate Loan Interests (509,251) Rights -- Transfers In Senior Floating-Rate Loan Interests -- Rights -- Transfers Out Senior Floating-Rate Loan Interests -- Rights -- -------------- ENDING BALANCE AT APRIL 30, 2016 Senior Floating-Rate Loan Interests 890,122 Rights --* -------------- Total Level 3 holdings $ 890,122 ============== * Investment is valued at $0.

Page 22 See Notes to Financial Statements -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust Senior Loan Fund (the "Fund"), which trades under the ticker "FTSL" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are generally issued and redeemed for cash and, in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the shares are not redeemable securities of the Fund. The Fund's primary investment objective is to provide high current income. The Fund's secondary investment objective is the preservation of capital. The Fund pursues its objectives by investing at least 80% of its net assets (plus the amount of any borrowing for investment purposes) under normal market conditions in a diversified portfolio of first lien senior floating rate loan interests ("Senior Loans")(1). A Senior Loan is an advanced or commitment of funds made by one or more banks or similar financial institutions to one or more corporations, partnerships or other business entities and typically pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate, most commonly the London Interbank Offered Rate ("LIBOR"). The Fund invests primarily in Senior Loans that are below investment grade quality at the time of investment. The Fund invests in Senior Loans made predominantly to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. 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 is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund's investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), 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. The Fund's investments are valued as follows: Senior Loans in which the Fund invests are not listed on any securities exchange or board of trade. Senior Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of Senior Loans ----------------------------- (1) The terms "security" and "securities" used throughout the Notes to Financial Statements include Senior Loans. Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) than for other types of securities. Typically, Senior Loans are valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans. Corporate bonds, corporate notes and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by an independent pricing service approved by the Trust'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. 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. Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 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 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 borrower/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 a security; 4) the financial statements of the borrower/issuer; 5) the credit quality and cash flow of the borrower/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 borrower/issuer, or comparable companies; 8) the coupon payments; Page 24 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) 9) the quality, value and salability of collateral, if any, securing the security; 10) the business prospects of the borrower/issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the borrower's/issuer's management; 11) the prospects for the borrower's/issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry; 12) borrower's/issuer's competitive position within the industry; 13) borrower's/issuer's ability to access additional liquidity through public and/or private markets; and 14) 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: 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 the Fund's investments as of April 30, 2016, is included with the 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. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method over the expected life of each respective borrowing for loans. 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. Due to the nature of the Senior Loan market, the actual settlement date may not be certain at the time of the purchase or sale for some of the Senior Loans. Interest income on such Senior Loans is not accrued until settlement date. 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. The Fund had no when-issued, delayed-delivery, or forward purchase commitments (other than unfunded commitments discussed below) as of April 30, 2016. C. UNFUNDED LOAN COMMITMENTS The Fund may enter into certain credit agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrower's discretion. The Fund had unfunded delayed drawn loan commitments of $95,186 as of April 30, 2016. D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom the shares were purchased makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker. Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) Distributions from net investment income and realized capital gains are determined in accordance with 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 time in the future. The tax character of distributions paid during the fiscal year ended October 31, 2015 was as follows: Distributions Distributions Distributions paid from paid from paid from Ordinary Capital Return of Income Gains Capital ------------- ------------- ------------- $ 10,638,104 $ -- $ -- As of October 31, 2015, the components of distributable earnings on a tax basis for the Fund were as follows: Accumulated Net Undistributed Capital and Unrealized Ordinary Other Appreciation Income Gains (Loss) (Depreciation) ------------- ------------- ------------- $ 397,650 $ (496,979) $ (9,548,485) E. 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. As of October 31, 2015, the Fund had $496,979 of non-expiring capital loss carryforwards that may be carried forward indefinitely. 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, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2013, 2014 and 2015 remain open to federal and state audit. As of April 30, 2016, 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. 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 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 securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Page 26 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund's assets and is responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.85% of its average daily net assets. 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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, or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and the 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. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2016, the cost of purchases and proceeds from sales of investments, excluding short-term investments and in-kind transactions, were $228,451,112 and $154,427,674, respectively. For the six months ended April 30, 2016, there were no in-kind transactions. 5. BORROWINGS The Trust, on behalf of the Fund, along with First Trust Exchange-Traded Fund III and First Trust Series Fund entered into a $140 million Credit Agreement with The Bank of Nova Scotia ("Scotia") as administrative agent for a group of lenders. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans. Prior to March 9, 2016, the commitment amount was $80 million and the commitment fee was 0.15%. First Trust allocates the commitment fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended April 30, 2016. 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. The Fund's Creation Units are generally issued and redeemed for cash. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a standard redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 7. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 8. INDEMNIFICATION The Trust, on behalf of the Fund, 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. 9. SUBSEQUENT EVENTS Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were issued, and has determined that there was the following subsequent event: On May 19, 2016, the Fund declared a distribution of $0.15 per share to shareholders of record on May 24, 2016, payable May 31, 2016.

YOU SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV. The following summarizes some of the risks that should be considered for the Fund. BANK LOAN RISK: An investment in Senior Loans subjects the Fund to credit risk, which is heightened for Senior Loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. Senior Loans are usually rated below investment grade but may also be unrated. An economic downturn would generally lead to a higher non-payment rate, and a Senior Loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a Senior Loan may decline in value or become illiquid, which would adversely affect the loan's value. Unlike the securities markets, there is no central clearinghouse for Senior Loan trades, and the Senior Loan market has not established enforceable settlement standards or remedies for failure to settle. Therefore, portfolio transactions in Senior Loans may have uncertain settlement time periods. Senior Loans are subject to a number of risks described elsewhere in this prospectus, including liquidity risk and the risk of investing in below investment grade fixed-income instruments. CALL RISK. If an issuer calls higher-yielding securities held by the Fund, performance could be adversely impacted. CASH TRANSACTION RISK: The Fund currently intends to effect a significant portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an exchange-traded fund that effects its creations and redemptions for in-kind securities. Because the Fund principally effects redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses, and may also result in higher brokerage costs. CONVERTIBLE BONDS RISK. The market values of convertible bonds tend to decline as interest rates increase and, conversely, to increase as interest rates decline. A convertible bond's market value also tends to reflect the market price of the common stock of the issuing company. 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. Credit risk may be heightened for the Fund because it may invest a substantial portion of its net assets in high yield or "junk" debt; such securities, while generally offering higher yields than investment-grade debt with similar maturities, involve greater risks, including the possibility of dividend or interest deferral, default or bankruptcy, and are regarded as predominantly speculative with respect to the issuer's capacity to pay dividends or interest and repay principal. Credit risk is heightened for loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. Page 29 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) CURRENCY RISK. Because the Fund's net asset value is determined on the basis of U.S. dollars and the Fund invests in foreign securities, you may lose money if the local currency of a foreign market depreciates against the U.S. dollar, even if the local currency value of the Fund's holdings goes up. The Fund intends to hedge its non-U.S. dollar holdings. HIGH YIELD SECURITIES RISK: High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, may be highly speculative. These securities are issued by companies that may have limited operating history, narrowly focused operations, and/or other impediments to the timely payment of periodic interest and principal at maturity. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. ILLIQUID SECURITIES RISK. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. INCOME RISK: If interest rates fall, the income from the Fund's portfolio will likely decline because the Fund holds floating rate debt that will adjust lower with falling interest rates. For loans, interest rates typically reset periodically. INTEREST RATE RISK: Interest rate risk is the risk that the value of the debt securities in the Fund will decline because of rising market interest rates. Interest rate risk is generally lower for shorter-term investments and higher for longer-term investments. Duration is a common measure of interest rate risk, which measures a bond's expected life on a present value basis, taking into account the bond's yield, interest payments and final maturity. Duration is a reasonably accurate measure of a bond's price sensitivity to changes in interest rates. The longer the duration of a bond, the greater the bond's price sensitivity is to changes in interest rates. LIQUIDITY RISK: The Fund invests a substantial portion of its assets in lower-quality debt issued by companies that are highly leveraged. Lower-quality debt tends to be less liquid than higher-quality debt. Moreover, smaller debt issues tend to be less liquid than larger debt issues. If the economy experiences a sudden downturn, or if the debt markets for such companies become distressed, the Fund may have particular difficulty selling its assets in sufficient amounts, at reasonable prices and in a sufficiently timely manner to raise the cash necessary to meet any potentially heavy redemption requests by Fund shareholders. MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the Advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objectives. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value generally or could underperform other investments. NON-DIVERSIFICATION RISK: The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended. As a result, the Fund is only limited as to the percentage of its assets that may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers. NON-U.S. SECURITIES RISK: Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Page 30 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SENIOR LOAN FUND (FTSL) APRIL 30, 2016 (UNAUDITED) OTHER DEBT SECURITIES RISK: Secured loans that are not first lien, loans that are unsecured and debt securities are subject to many of the same risks that affect Senior Loans; however they are often unsecured and/or lower in the issuer's capital structure than Senior Loans, and thus may be exposed to greater risk of default and lower recoveries in the event of a default. This risk can be further heightened in the case of below investment grade instruments. Additionally, most fixed-income securities are fixed-rate and thus are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. PREPAYMENT RISK: Loans are subject to pre-payment risk. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan. Page 31 This page intentionally left blank.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) The primary investment objective of the First Trust Tactical High Yield ETF (the "Fund") is to provide current income. The Fund's secondary investment objective is to provide capital appreciation. The Fund seeks to achieve its investment objectives by investing at least 80% of its net assets including investment borrowings, under normal market conditions, in high yield debt securities that are rated below investment grade at the time of purchase or unrated securities deemed by the Fund's advisor to be of comparable quality. Below investment grade securities are those that, at the time of purchase, are rated lower than "BBB-" by Standard & Poor's Ratings Group, a division of the McGraw Hill Companies, Inc., or lower than "Baa3" by Moody's Investors Service, Inc., or comparably rated by another nationally recognized statistical rating organization. High yield debt securities that are rated below investment grade are commonly referred to as "junk" bonds. Such securities may include U.S. and non-U.S. corporate debt obligations, bank loans and convertible bonds. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. There can be no assurance that the Fund's investment objective will be achieved. The Fund may not be appropriate for all investors. ------------------------------------------------------------------------------------------------------------------- PERFORMANCE ------------------------------------------------------------------------------------------------------------------- AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (2/25/13) Inception (2/25/13) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 1.26% 0.21% 4.56% 15.20% Market Price 1.00% 0.14% 4.56% 15.21% INDEX PERFORMANCE BofA Merrill Lynch US High Yield Constrained Index 2.25% -1.33% 3.31% 10.89% ------------------------------------------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Annual Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the 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 the 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 the Fund at NAV and Market Price, respectively. 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. 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 index. 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 the shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance.

A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations except for those debt obligations that are only privately rated. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.

This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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 BEGINNING ENDING BASED ON THE EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE SIX-MONTH DURING THE NOVEMBER 1, 2015 APRIL 30, 2016 PERIOD SIX-MONTH PERIOD (a) -------------------------------------------------------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) Actual $1,000.00 $1,012.60 1.16% $5.80 Hypothetical (5% return before expenses) $1,000.00 $1,019.10 1.16% $5.82 (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, 2015 through April 30, 2016), multiplied by 182/366 (to reflect the one-half year period).

(b) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A under the Securities Act of 1933, as amended (the "1933 Act"), and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P., the Fund's advisor (the "Advisor"). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. At April 30, 2016, securities noted as such amounted to $258,584,462 or 32.4% of net assets. (c) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under 144A under the 1933 Act, and may be resold in transactions exempt from registration, normally to qualified institutional buyers (see Note 2E - Restricted Securities in the Notes to Financial Statements). (d) Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be illiquid by the Advisor. (e) These notes are Senior Payment-In-Kind ("PIK") Toggle Notes whereby the issuer may, at its option, elect to pay interest on the notes (1) entirely in cash or (2) entirely in PIK interest. Interest paid in cash will accrue at the rate of 7.00% per annum ("Cash Interest Rate") and PIK interest will accrue on the notes at a rate per annum equal to the Cash Interest Rate plus 75 basis points. For the six months ended April 30, 2016, this security paid all of its interest in cash. (f) Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more United States banks or (iii) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR floor that establishes a minimum LIBOR rate. The interest rate shown reflects the rate in effect at April 30, 2016. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche at varying rates. (g) Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown. (h) This security is fair valued by the Advisor's Pricing Committee in accordance with procedures adopted by the Trust's Board of Trustees and in accordance with provisions of the Investment Company Act of 1940, as amended. At April 30, 2016, securities noted as such are valued at $464,470 or 0.06% of net assets. (i) This issuer has filed for protection in federal bankruptcy court. (j) This issuer is in default but interest is still being accrued by the Fund and paid by the issuer. (k) Interest rate shown reflects yield as of April 30, 2016. (l) Aggregate cost for financial reporting purposes, which approximates the aggregate cost for federal income tax purposes. As of April 30, 2016, the aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $11,564,002 and the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $17,553,235.

Industry categories are only shown separately if they include holdings in two or more levels or have holdings in only Level 3. There were no transfers between Level 1 and Level 2. All transfers in and out of Level 3 during the period are assumed to be transferred on the last day of the period at their current value. As of April 30, 2016, the Fund transferred Senior Floating-Rate Loan Interests valued at $134,539 from Level 2 to Level 3 of the fair value hierarchy. The Senior Floating-Rate Loan Interests that transferred from Level 2 to Level 3 did so primarily as a result of a change in information obtained from an independent third-party pricing service relating to the market activity of individual Senior Floating-Rate Loan Interests and a lack of trading activity in certain Senior Floating-Rate Loan Interests. As of April 30, 2016, the Fund transferred Corporate Bonds valued at $1,010,610 from Level 2 to Level 3 of the fair value hierarchy. The Corporate Bonds that transferred from Level 2 to Level 3 did so primarily as a result of a change in information obtained from an independent third-party pricing service relating to the market activity of individual Corporate Bonds and a lack of trading activity in certain Corporate Bonds. Level 3 Senior Floating-Rate Loan Interests that are fair valued by the Advisor's Pricing Committee are footnoted in the Portfolio of Investments. Level 3 Senior Floating-Rate Loan Interests are valued based on either third-party pricing services prices obtained from dealer runs and indicative sheets from brokers or are valued using broker quotes. The values are based on unobservable and non-quantitative inputs. The Trust's Board of Trustees has adopted valuation procedures that are utilized by the Advisor's Pricing Committee to oversee day-to-day valuation of the Fund's investments. The Advisor's Pricing Committee, through the Fund's fund accounting agent, monitors daily pricing via tolerance checks and stale and unchanged price reviews. The Advisor's Pricing Committee also reviews monthly back testing of pricing service prices by comparing sales prices of the Fund investments to prior day pricing service prices. Additionally, the Advisor's Pricing Committee reviews periodic information from the Fund's third-party pricing service that compares secondary market trade prices to their daily valuations.

See Notes to Financial Statements Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust Tactical High Yield ETF (the "Fund"), which trades under the ticker "HYLS" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are generally issued and redeemed for cash and, in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The primary investment objective of the Fund is to provide current income. The Fund's secondary investment objective is to provide capital appreciation. The Fund seeks to achieve its investment objectives by investing at least 80% of its net assets including investment borrowings, under normal market conditions, in high yield debt securities that are rated below investment grade at the time of purchase or unrated securities deemed by the Fund's advisor to be of comparable quality. Below investment grade securities are those that, at the time of purchase, are rated lower than "BBB-" by Standard & Poor's Ratings Group, a division of the McGraw Hill Companies, Inc., or lower than "Baa3" by Moody's Investors Service, Inc., or comparably rated by another nationally recognized statistical rating organization. High yield debt securities that are rated below investment grade are commonly referred to as "junk" bonds. Such securities may include U.S. and non-U.S. corporate debt obligations, bank loans and convertible bonds. For purposes of determining whether a security is below investment grade, the lowest available rating will be considered. There can be no assurance that the Fund's investment objective will be achieved. The Fund may not be appropriate for all investors. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. 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 is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Advisor's Pricing Committee in accordance with valuation procedures adopted by the 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. The Fund's investments are valued as follows: Corporate bonds, corporate notes, U.S. government securities and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by an independent pricing service approved by the Trust'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. Page 26 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 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. Senior Loans(1) in which the Fund invests are not listed on any securities exchange or board of trade. Senior Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of Senior Loans than for other types of securities. Typically, Senior Loans are fair valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans. Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 (the "1933 Act")) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of 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 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 borrower/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 a security; 4) the financial statements of the borrower/issuer; 5) the credit quality and cash flow of the borrower/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 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 borrower/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 borrower's/issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry; 12) borrower's/issuer's competitive position within the industry; 13) borrower's/issuer's ability to access additional liquidity through public and/or private markets; and 14) other relevant factors. ----------------------------- (1) The terms "security" and "securities" used throughout the Notes to Financial Statements include Senior Loans. Page 27 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 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: 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 the Fund's investments as of April 30, 2016, is included with the 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. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method over the expected life of each respective borrowing for loans. 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. Due to the nature of the Senior Loan market, the actual settlement date may not be certain at the time of the purchase or sale for some of the Senior Loans. Interest income on such Senior Loans is not accrued until settlement date. 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. The Fund did not have any when-issued, delayed-delivery, or forward purchase commitments as of April 30, 2016. C. SHORT SALES Short sales are utilized for investment and risk management purposes and are transactions in which securities or other instruments (such as options, forwards, futures or other derivative contracts) are sold that are not currently owned in the Fund's portfolio. When the Fund engages in a short sale, the Fund must borrow the security sold short and deliver the security to the counterparty. Short selling allows the Fund to profit from a decline in a market price to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. The Fund is charged a fee or premium to borrow the securities sold short and is obligated to repay the lenders of the securities. Any dividends or interest that accrues on the securities during the period of the loan are due to the lenders. A gain, limited to the price at which the security was sold short, or a loss, unlimited in size, will be recognized upon the termination of the short sale; which is effected by the Fund purchasing the security sold short and delivering the security to the lender. Any such gain or loss may be offset, completely or in part, by the change in the value of the long portion of the Fund's portfolio. The Fund is subject to the risk it may be unable to reacquire a security to terminate a short position except at a price substantially in excess of the last quoted price. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. The Fund has established an account with Pershing, LLC for the purpose of purchasing or borrowing securities on margin. The Fund pays interest on any margin balance, which is calculated as the daily margin account balance times the broker's margin interest rate. At April 30, 2016, the Fund had $59,754,471 in restricted cash associated with investments sold short and $63,483,097 of investments sold short as shown on the Statement of Asset and Liabilities. Interest is charged on these balances at a rate equal to the Federal Funds rate plus 75 basis points and is charged on payable credit margin balances at a rate equal to the Federal Funds rate less 40 basis points. At April 30, 2016, the Fund had a debit margin balance with an interest rate of 1.04%. For the six months ended April 30, 2016, margin interest expense was $86,438, which is shown in "Margin interest expense" on the Statement of Operations. For the six months ended April 30, 2016, the average margin balance and interest rates were $16,135,229 and 1.04%, respectively. Page 28 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) D. UNFUNDED LOAN COMMITMENTS The Fund may enter into credit agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrower's discretion. The Fund had no unfunded loan commitments as of April 30, 2016. E. RESTRICTED SECURITIES The Fund invests in restricted securities, which are securities that may not be offered for public sale without first being registered under the 1933 Act. Prior to registration, restricted securities may only be resold in transaction exempt from registration under Rule 144A under the 1933 Act, normally to qualified institutional buyers. As of April 30, 2016, the Fund held restricted securities as shown in the following table that the Advisor has deemed illiquid pursuant to procedures adopted by the Fund's Board of Trustees. Although market instability can result in periods of increaded overall market illiquidity, liquidity for each security is determined based on security-specified factors and assumptions, which require subjective judgement.The Fund does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security. There are no unrestricted securities with the same maturity dates and yields for these issuers. ACQUISITION PAR CURRENT CARRYING % OF NET SECURITY DATE AMOUNT PRICE COST VALUE ASSETS ------------------------ -------------- ------------- ------------- ------------- ------------- ------------- Pinnacle Operating Corp., 9.00%, 11/15/20 9/13/13-12/19/14 $ 1,182,000 $ 85.50 $ 1,211,260 $ 1,010,610 0.13% F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom the shares were purchased makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker. 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 significantly modified 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 time in the future. The tax character of distributions paid during the fiscal year ended October 31, 2015 was as follows: Distributions paid from: Ordinary income................................. $ 24,914,521 Capital gain.................................... -- Return of capital............................... 332,485 As of October 31, 2015, the components of distributable earnings on a tax basis for the Fund were as follows: Undistributed ordinary income................... $ -- Accumulated capital and other losses............ (930,645) Net unrealized appreciation (depreciation)...... (15,965,702) G. 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. Page 29 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 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. As of October 31, 2015, the Fund has non-expiring capital loss carryforwards of $930,645 for federal income tax purposes. 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. 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, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2013, 2014 and 2015 remain open to federal and state audit. As of April 30, 2016, 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. H. EXPENSES Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 3). The Fund is subject to an interest expense due to the costs associated with the Fund's short positions in securities. 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 securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund's assets and is responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. During the year ended October 31, 2015, the Fund received a payment from the Advisor of $24,541 in connection with a trade error. 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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 or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2016, the cost of purchases and proceeds from sales of investments, excluding short-term investments and in-kind transactions, were $312,763,481 and $77,734,480, respectively. For the six months ended April 30, 2016, the Fund had no in-kind transactions. Page 30 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 5. BORROWINGS The Trust, on behalf of the Fund, along with the First Trust Series Fund and First Trust Variable Insurance Trust, entered into a $135 million Credit Agreement ("Line of Credit") with BNYM, to be a liquidity backstop during periods of high redemption volume. A commitment fee of 0.15% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans will be charged by BNYM, which First Trust allocates amongst the funds that had access to the Line of Credit. To the extent that the Fund accesses the Line of Credit, there would also be an interest fee charged. For the six months ended April 30, 2016, the Fund did not have any outstanding borowings under the Line of Credit. 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Partcipant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of equity securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. The Fund's Creation Units are generally issued and redeemed for cash. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 7. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 8. INDEMNIFICATION The Trust, on behalf of the Fund, 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.

YOU SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV. The following summarizes some of the risks that should be considered for the Fund. BANK LOANS RISK. An investment in bank loans subjects the Fund to credit risk, which is heightened for bank loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. Senior Loans, in which the Fund may invest, are usually rated below investment grade but may also be unrated. As a result, the risks associated with these Senior Loans are similar to the risks of high yield fixed income instruments. An economic downturn would generally lead to a higher non-payment rate, and a Senior Loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a Senior Loan may decline in value or become illiquid, which would adversely affect the Senior Loan's value. Unlike the securities markets, there is no central clearinghouse for loan trades, and the loan market has not established enforceable settlement standards or remedies for failure to settle. Therefore, portfolio transactions in Senior Loans may have uncertain settlement time periods. Senior Loans are subject to a number of risks described elsewhere in this prospectus, including liquidity risk and the risk of investing in below investment grade fixed income instruments. Furthermore, increases in interest rates may result in greater volatility of Senior Loans and average duration may fluctuate with fluctuations in interest rates. CALL RISK: If an issuer calls higher-yielding securities held by the Fund, performance could be adversely impacted. CASH TRANSACTIONS RISK: The Fund will, under most circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an exchange-traded fund that effects its creations and redemption for in-kind securities. Because the Fund may effect a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses and may also result in higher brokerage costs. CONVERTIBLE BONDS RISK: The market values of convertible bonds tend to decline as interest rates increase and, conversely, to increase as interest rates decline. A convertible bond's market value also tends to reflect the market price of the common stock of the issuing company. COUNTERPARTY RISK: Certain Derivative Instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty's bankruptcy or failure to perform its obligations. In the event of default, the Fund could experience lengthy delays in recovering some or all of its assets or no recovery at all. The Fund's investments in the futures markets also introduce the risk that its futures commission merchant ("FCM") would default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM's obligation to return margin posted in connection with the Fund's futures contracts. Page 33 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) 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. Credit risk may be heightened for the Fund because it invests a substantial portion of its net assets in high yield or "junk" debt; such securities, while generally offering higher yields than investment grade debt with similar maturities, involve greater risks, including the possibility of dividend or interest deferral, default or bankruptcy, and are regarded as predominantly speculative with respect to the issuer's capacity to pay dividends or interest and repay principal. Credit risk is heightened for loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. CURRENCY RISK: Because the Fund's net asset value is determined on the basis of U.S. dollars and the Fund invests in foreign securities, you may lose money if the local currency of a foreign market depreciates against the U.S. dollar, even if the local currency value of the Fund's holdings goes up. The Fund intends to hedge its non-U.S. dollar holdings. DERIVATIVES RISK: The use of Derivative Instruments can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the Derivative Instruments. These risks are heightened when the 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. DISTRESSED SECURITIES RISK: The Fund may invest in Distressed Securities, including stressed, distressed and bankrupt issuers and debt obligations that are in default. In any investment involving Distressed Securities, there exists the risk that the transaction involving such securities will be unsuccessful. Distressed Securities might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. Many Distressed Securities are illiquid or trade in low volumes and thus may be more difficult to value. Companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations or financial restructurings are referred to herein as "Distressed Securities." HIGH YIELD SECURITIES RISK: High yield securities are subject to greater market fluctuations and risk of loss than securities with higher ratings. These securities are issued by companies that may have limited operating history, narrowly focused operations, and/or other impediments to the timely payment of periodic interest and principal at maturity. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. ILLIQUID SECURITIES RISK: Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. INCOME RISK: If interest rates fall, the income from the Fund's portfolio will decline as the Fund invests the proceeds from new share sales, or from matured or called debt securities, at interest rates that are below the portfolio's current earnings rate. INTEREST RATE RISK: Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. In general, duration represents the expected percentage in the value of a security for an immediate 1% change in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. LIQUIDITY RISK: The Fund invests a substantial portion of its assets in lower-quality debt issued by companies that are highly leveraged. Lower-quality debt tends to be less liquid than higher-quality debt. Moreover, smaller debt issues tend to be less liquid than larger debt issues. If the economy experiences a sudden downturn, or if the debt markets for such companies become distressed, the Fund may have particular difficulty selling its assets in sufficient amounts, at reasonable prices and in a sufficiently timely manner to raise the cash necessary to meet any potentially heavy redemption requests by Fund shareholders. As of the fourth quarter of 2015, the market for high yield debt has experienced decreased liquidity, and investor perception of increased risk has caused yield spreads to widen. Decreased liquidity may negatively affect the Fund's ability to mitigate risk and meet redemptions. Page 34 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) APRIL 30, 2016 (UNAUDITED) MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objectives. MARKET RISK: Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in stock prices. Overall stock values could decline generally or could underperform other investments. NON-U.S. SECURITIES RISK: Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. OTHER DEBT SECURITIES RISK: Secured loans that are not first lien, loans that are unsecured and debt securities are subject to many of the same risks that affect senior loans; however they are often unsecured and/or lower in the issuer's capital structure than senior loans, and thus may be exposed to greater risk of default and lower recoveries in the event of a default. This risk can be further heightened in the case of below investment grade instruments. Additionally, most fixed-income securities are fixed-rate and thus are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. PREPAYMENT RISK: Loans are subject to pre-payment risk. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan. SHORT SALE RISK: The Fund uses short sales for investment and risk management purposes, including when the Fund's advisor anticipates that the market price of securities will decline or in the aggregate will underperform the Index. In times of unusual or adverse market, economic, regulatory or political conditions, the Fund may not be able, fully or partially, to implement its short selling strategy. Periods of unusual or adverse market, economic, regulatory or political conditions may exist for relatively long periods of time. The Fund will have substantial short positions and must borrow those securities to make delivery to the buyer. The Fund may not be able to borrow a security that it needs to deliver or it may not be able to close out a short position at an acceptable price and may have to sell related long positions before it had intended to do so. Thus, the Fund may not be able to successfully implement its short sale strategy due to limited availability of desired securities or for other reasons. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. Page 35 This page intentionally left blank.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) The investment objective of First Trust Enhanced Short Maturity ETF (the "Fund") is to seek current income, consistent with preservation of capital and daily liquidity. Under normal market conditions, the Fund intends to achieve its investment objective by investing at least 80% of its net assets in a portfolio of U.S. dollar-denominated fixed- and variable-rate instruments (collectively, "Fixed Income Securities") issued by U.S. and non-U.S. public and private sector entities. Fixed Income Securities will include the following types of fixed- and variable-rate debt securities: corporate and government bonds and notes; agency securities; instruments of non-U.S. issuers in developed markets; privately issued securities; asset-backed securities; mortgage-related securities; municipal bonds; and money market securities. Shares of the Fund are listed on The Nasdaq Stock Market LLC under the ticker symbol "FTSM." The Fund's investment advisor, First Trust Advisors L.P. (the "Advisor") selects securities for the portfolio by evaluating fixed income sectors and macro market trends while completing bottom-up analysis of individual securities. Portfolio securities are selected based upon relative value in the context of overall portfolio duration. Key inputs for the screens in the securities selection process include, but are not limited to, credit quality, yield, interest rate sensitivity and liquidity. The Fund's holdings are systematically monitored for meaningful changes in performance and risk measures. A security will generally be sold when the Advisor believes that a security can be substituted for a similar investment that represents better relative value; it lacks adequate compensation for embedded credit risk; or when rebalancing the portfolio to maintain diversification. Under normal market conditions, the Fund's average duration is expected to be below one year and the average maturity of the Fund's portfolio is expected to be below three years. -------------------------------------------------------------------------------------------------------------------------- PERFORMANCE -------------------------------------------------------------------------------------------------------------------------- ANNUAL AVERAGE CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (8/5/14) Inception (8/5/14) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 0.34% 0.32% 0.46% 0.79% Market Price 0.38% 0.32% 0.44% 0.76% INDEX PERFORMANCE BofA Merrill Lynch 0-1 Year U.S. Treasury Index 0.25% 0.34% 0.26% 0.45% -------------------------------------------------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the 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 the 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 the Fund at NAV and Market Price, respectively. 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. 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance.

FRIES, CFA - SENIOR VICE PRESIDENT, PORTFOLIO MANAGER Page 5 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust Enhanced Short Maturity ETF (the "Fund"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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, 2015 APRIL 30, 2016 PERIOD (a) PERIOD (b) ------------------------------------------------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) Actual $1,000.00 $1,003.40 0.24% $1.20 Hypothetical (5% return before expenses) $1,000.00 $1,023.67 0.24% $1.21 (a) These expense ratios reflect expense waivers.

The interest rate shown reflects the rate in effect at April 30, 2016. (b) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A under the Securities Act of 1933, as amended, and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P., the Fund's advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At April 30, 2016, securities noted as such amounted to $14,266,354 or 3.8% of net assets. (c) Aggregate cost for financial reporting purposes, which approximates the aggregate cost for federal income tax purposes. As of April 30, 2016, the aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $225,041 and the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $226,143.

See Notes to Financial Statements Page 21 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust Enhanced Short Maturity ETF (the "Fund"), which trades under the ticker "FTSM" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are generally issued and redeemed for cash, and in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is an actively managed exchange-traded fund ("ETF"). The Fund's investment objective is to seek current income, consistent with preservation of capital and daily liquidity. Under normal market conditions, the Fund will invest at least 80% of its net assets in a portfolio of U.S. dollar-denominated fixed- and variable-rate instruments (collectively, "Fixed Income Securities") issued by U.S. and non-U.S. public and private sector entities. Fixed Income Securities will include the following types of fixed- and variable-rate debt securities: corporate and government bonds and notes; agency securities; instruments of non-U.S. issuers in developed markets; privately issued securities; asset-backed securities; mortgage-related securities; municipal bonds and money market securities. The Fund may also invest in investment companies, such as ETFs, that invest in primarily Fixed Income Securities. The Fund will limit its investments in asset-backed securities and non-agency mortgage-backed securities (in the aggregate) to 20% of its net assets. The Fund may also invest up to 20% of its net assets in floating rate loans. The floating rate loans will represent amounts borrowed by companies or other entities from banks and other lenders and a significant portion of such floating rate loans may be rated below investment grade or unrated. Floating rate loans held by the Fund may be senior or subordinate obligations of the borrower and may or may not be secured by collateral. Under normal market conditions, the Fund's average duration is expected to be below one year and the average maturity of the Fund's portfolio is expected to be below three years. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. 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 is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund's investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), 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. The Fund's investments are valued as follows: Corporate bonds, corporate notes, municipal securities, 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 an independent pricing service approved by the Trust'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; Page 22 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) 5) benchmark securities; 6) bids and offers; and 7) reference data including market research publications. Common stocks and other equity securities listed on any national or foreign exchange (excluding 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 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. Commercial paper, fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 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 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 borrower/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 a security; 4) the financial statements of the borrower/issuer; 5) the credit quality and cash flow of the borrower/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 of the borrower/issuer, 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 borrower/issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the borrower's/issuer's management (for corporate debt only); 11) the prospects for the borrower's/issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); 12) the borrower's/issuer's competitive position within the industry; 13) the borrower's/issuer's ability to access additional liquidity through public and/or private markets; and 14) 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: Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) 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 the Fund's investments as of April 30, 2016, is included with the 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 is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method. C. AFFILIATED TRANSACTIONS The Fund invests in an affiliated fund. Dividend income, realized gains and losses, and change in appreciation (depreciation) from the affiliated fund are presented on the Statement of Operations. The Fund's investment performance and risks are directly related to the investment performance and risks of the affiliated fund. Amounts related to this investment for the six months ended April 30, 2016 are as follows: SHARE ACTIVITY ----------------------------------------------------- BALANCE AT BALANCE AT VALUE AT DIVIDEND REALIZED SECURITY NAME 10/31/15 PURCHASES SALES 4/30/16 4/30/16 INCOME GAIN (LOSS) ---------------------------- ----------- ----------- ----------- ----------- ------------ ----------- ----------- First Trust Senior Loan Fund 147,215 -- (147,215) -- $ -- $ 30,312 $ (223,734) D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom the shares were purchased makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker. Distributions from net investment income and realized capital gains are determined in accordance with 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 time in the future. The tax character of distributions paid during the fiscal year ended October 31, 2015 was as follows: Distributions paid from: Ordinary income................................. $ 2,887,800 Capital gain.................................... -- Return of capital............................... -- Page 24 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) As of October 31, 2015, the components of distributable earnings and net assets on a tax basis for the Fund were as follows: Undistributed ordinary income................... $ 413,174 Accumulated capital and other losses............ (1,505,466) Net unrealized appreciation (depreciation)...... (337,236) E. 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, 2015, the Fund had $1,505,466 of non-expiring capital loss carryforwards that may be carried forward indefinitely. 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, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2014 and 2015 remain open to federal and state audit. As of April 30, 2016, 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. 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 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 securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Pursuant to the Investment Management Agreement between the Trust and Advisor, First Trust manages the investment of the Fund's assets and is responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses with the exception of those attributable to affiliated funds, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.45% of its average daily net assets. Pursuant to contractual agreements, First Trust has agreed to waive management fees of 0.20% of average daily net assets until March 1, 2017. The waiver agreement may be terminated by action of the Trust's Board of Trustees at any time upon 60 days' written notice by the Trust on behalf of the Fund or by the Fund's investment advisor only after March 1, 2017. Pursuant to a contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the portion of the management fees earned by First Trust from the Fund for assets invested in other investment companies advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Trust's Board of Trustees or (ii) upon termination of the Fund's management agreement with First Trust; however, it is expected to remain in place at least until March 1, 2017. First Trust does not have the right to recover the fees waived that are attributable to the assets invested in other investment companies advised by First Trust. Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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 or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen will rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. REVERSE STOCK SPLIT On October 29, 2014, the Trust's Board of Trustees approved a one-for-two reverse stock split, whereby each share of the Fund outstanding as of the close of business on November 7, 2014 automatically converted to one-half share as of the opening of business on November 10, 2014. For the fiscal year ended October 31, 2015, the share transactions on the Statements of Changes in Net Assets reflect the actual transactions, including the impact of the reverse stock split. As a result of the reverse stock split, fractional shares totaling 277 shares were redeemed and paid out to shareholders. The reverse stock split had no impact on the overall value of a shareholder's investment in the Fund. 5. PURCHASES AND SALES OF SECURITIES The cost of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016, were $32,333,399 and $109,129,826, respectively. The proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016 were $14,620,661 and $66,204,522, respectively. For the six months ended April 30, 2016, the Fund had no in-kind transactions. 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. The Fund's Creation Units are generally issued and redeemed for cash. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Page 26 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 7. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 8. INDEMNIFICATION The Trust, on behalf of the Fund, 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. 9. SUBSEQUENT EVENTS Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were issued, and has determined there was the following subsequent event: On May 19, 2016, the Fund declared a distribution of $0.045 per share to shareholders of record on May 24, 2016, payable May 31, 2016.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objective will be achieved. ASSET-BACKED AND MORTGAGE-RELATED SECURITIES RISK. The risk of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk and prepayment risk. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making them more sensitive to changes in interest rates. Extension risk is prevalent when in a period of rising interest rates, the Fund holds mortgage-related securities and such securities exhibit additional volatility. Prepayment risk is prevalent when in a period of declining interest rates, borrowers may pay off their mortgages sooner than expected. Prepayments can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. The Fund's investments in asset-backed securities are subject to risks similar to those associated with mortgage-related securities, as well as additional risks associated with the nature of the assets and the servicing of those assets. CALL RISK. If an issuer calls higher yielding debt instruments held by the Fund, performance could be adversely impacted. CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a portion of creations and redemptions for cash, rather than in kind securities. As a result, an investment in the Fund may be less tax efficient than an investment in an ETF that effects its creations and redemption for in kind securities. Because the Fund may effect a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses, and may also result in higher brokerage costs. 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. FIXED INCOME SECURITIES RISK. An investment in the Fund involves risk associated with an investment in fixed income securities including the risk that certain of the securities in the Fund may not have the benefit of covenants that would prevent the issuer from engaging in capital restructurings or borrowing transactions in connection with corporate acquisitions, leveraged buyouts or restructurings. This limitation could reduce the ability of the issuer to meet its payment obligations and might result in increased credit risk. In addition, certain of the securities may be redeemed or prepaid by the issuer, resulting in lower interest payments received by the Fund and reduced distributions to shareholders. FLOATING RATE LOAN RISK. An investment in floating rate loans subjects the Fund to credit risk, which is heightened for loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. The loans are usually rated below investment grade but may also be unrated. An economic downturn would generally lead to a higher non-payment rate, and a loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan's value. Unlike the securities markets, there is no central clearinghouse for loan trades, and the loan market has not established enforceable settlement standards or remedies for failure to settle. Therefore, portfolio transactions in loans may have uncertain settlement time periods. Loans are subject to a number of risks described elsewhere in this Page 28 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) prospectus, including liquidity risk and the risk of investing in below investment grade debt instruments. Floating rate loans are subject to prepayment risk. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan. HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, may be highly speculative. These securities are issued by companies that may have limited operating history, narrowly focused operations, and/or other impediments to the timely payment of periodic interest and principal at maturity. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is generally smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over the counter markets. Due to the smaller, less liquid market for high yield securities, the bid offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. In general, high yield securities may have a greater risk of default than other types of securities. ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be illiquid. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. INCOME RISK. Income from the Fund's fixed income investments could decline during periods of falling interest rates. INTEREST RATE RISK. Interest rate risk is the risk that the value of the Fixed Income Securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term Fixed Income Securities and higher for longer term Fixed Income Securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the Fixed Income Security's expected principal and interest payments. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. Therefore, prices of Fixed Income Securities with shorter durations tend to be less sensitive to interest rate changes than Fixed Income Securities with longer durations. As the value of a Fixed Income Security changes over time, so will its duration. Mortgage-related securities are particularly subject to the risk that interest rate volatility may adversely impact the valuation and price of such securities. INVESTMENT COMPANIES RISK. The Fund may invest in the shares of other investment companies, and therefore, the Fund's investment performance and risks may be related to the investment performance and risks of the underlying funds. In general, as a shareholder in other investment companies, the Fund bears its ratable share of the underlying fund's expenses, and would be subject to duplicative expenses to the extent the Fund invests in other investment companies. Pursuant to a contractual agreement, the Fund's investment advisor has agreed to reduce the management fee paid by the Fund by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided, that, the investment companies are advised by the Fund's investment advisor. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. The Fund's investment advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objectives. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall security values could decline generally or could underperform other investments. NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the Fund is only limited as to the percentage of its assets that may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers. Page 29 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM) APRIL 30, 2016 (UNAUDITED) NON-U.S. SECURITIES RISK. The Fund invests in securities of non-U.S. 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; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards and less government supervision and regulation of exchanges in foreign countries. PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and selling portfolio securities to rebalance the Fund's exposure to various market sectors. High portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund's performance to be less than you expect. SOVEREIGN DEBT RISK. Investments in debt securities issued by foreign governments ("Sovereign Debt") involve special risks because the governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities; the relative size of the debt service burden to the economy as a whole; or the government debtor's policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund's ability to obtain recourse may be limited. VOLATILITY RISK. The market price and net asset value of the Fund's shares and the Fund's yield will change daily. There may be instances when the Fund will experience large in flows and out flows, which will significantly alter the Fund's size. At times, these fluctuations may negatively impact the Fund's yield, result in increased transaction costs for the Fund and contribute to the overall volatility of the Fund. The risk will be more prevalent when the Fund is smaller in size, such as during the Fund's invest up period. An investor may lose money by investing in this Fund because this Fund is not a money market fund and may experience significant fluctuations in its net asset value.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) The primary investment objective of the First Trust Strategic Income ETF (the "Fund") is to seek risk-adjusted income. The Fund's secondary investment objective is capital appreciation. The Fund is a multi-manager, multi-strategy actively managed exchange-traded fund. First Trust Advisors L.P. ("First Trust" or the "Advisor") serves as the advisor. The Advisor's Investment Committee determines the Fund's strategic allocation among various general investment categories and allocates the Fund's assets to portfolio management teams comprised of personnel of the Advisor and/or a sub-advisor (each, a "Management Team"), which employ their respective investment strategies. Shares of the Fund are listed on The Nasdaq Stock Exchange LLC under the ticker symbol "FDIV." The Fund's investment categories are: (i) high yield corporate bonds, commonly referred to as "junk" bonds, and first lien senior secured floating rate bank loans; (ii) mortgage-related investments; (iii) preferred securities; (iv) international sovereign bonds, including emerging markets debt; (v) equity securities of Energy Infrastructure Companies, certain of which are master limited partnerships ("MLPs"); and (vi) dividend paying U.S. exchange-traded equity securities and depositary receipts. The Management Teams may utilize a related option overlay strategy and/or derivative instruments in implementing their respective investment strategies for the Fund. Additionally, the Management Team may seek to gain exposure to the Fund's investment categories through investments in exchange-traded funds. The Fund seeks to achieve its objectives by having each Management Team focus on those instruments within its respective investment category. The Fund may add or remove investment categories or Management Teams at the discretion of the Advisor. ----------------------------------------------------------------------------------------------------------------------------- PERFORMANCE ----------------------------------------------------------------------------------------------------------------------------- AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (8/13/14) Inception (8/13/14) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 4.47% 1.02% 2.52% 4.35% Market Price 2.11% -1.61% 0.87% 1.50% INDEX PERFORMANCE Blended Index(1) 2.78% -1.82% 0.03% 0.05% Barclays Capital U.S. Aggregate Bond Index 2.83% 2.74% 3.29% 5.70% Russell 3000(R) Index 0.06% -0.18% 4.84% 8.44% ----------------------------------------------------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the 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 the 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 the Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance. ----------------------------- (1) The Blended Index is equally weighted to include these six indices: the Alerian MLP Index, Dow Jones U.S. Select Dividend Index, BofA Merrill Lynch Fixed Rate Preferred Securities Index, BofA Merrill Lynch U.S. High Yield Index, Barclays EM USD Aggregate Index and Barclays U.S. MBS Index. An index does not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the index performance shown. Indices are unmanaged and an investor cannot invest directly in an index.

Page 4 FIRST TRUST STRATEGIC INCOME ETF (FDIV) UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust Strategic Income ETF (the "Fund"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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, 2015 APRIL 30, 2016 PERIOD (a) PERIOD (b) --------------------------------------------------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) Actual $1,000.00 $1,044.70 0.55% $2.80 Hypothetical (5% return before expenses) $1,000.00 $1,022.13 0.55% $2.77 (a) These expense ratios reflect expense waivers. See Note 3 in the Notes to Financial Statements. (b) Expenses are equal to the annualized expense ratio as indicated in the table, multiplied by the average account value over the period (November 1, 2015 through April 30, 2016), multiplied by 182/366 (to reflect the one-half year period).

Page 18 See Notes to Financial Statements -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust Strategic Income ETF (the "Fund"), which trades under the ticker "FDIV" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are generally issued and redeemed for cash and, in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is a multi-manager, multi-strategy actively managed exchange-traded fund. The Fund's primary investment objective is to seek risk-adjusted income. The Fund's secondary investment objective is capital appreciation. First Trust Advisors L.P. ("First Trust" or the "Advisor") is the investment advisor to the Fund. The following serve as investment sub-advisors to the Fund: First Trust Global Portfolios Ltd. ("FTGP"); Energy Income Partners, LLC ("EIP"); Stonebridge Advisors LLC ("Stonebridge"); and Richard Bernstein Advisors LLC ("RBA") (each, a "Sub-Advisor" and together, the "Sub-Advisors"). The Advisor's Investment Committee determines the Fund's strategic allocation among various general investment categories and allocates the Fund's assets to portfolio management teams comprised of personnel of the Advisor and/or a Sub-Advisor (each, a "Management Team"), which employ their respective investment strategies. The Fund seeks to achieve its objectives by having each Management Team focus on those investments within its respective investment category. The Fund may add or remove investment categories or Management Teams at the discretion of the Advisor. Under normal market conditions, the Fund will invest in various asset classes, which include high-yield corporate bonds, senior floating-rate loan interests, mortgage-related investments, preferred securities, international sovereign bonds, equity securities of Energy Infrastructure Companies(1), certain of which are master limited partnerships ("MLPs") and dividend paying U.S. exchange-traded equity securities and depositary receipts. The Management Team may utilize a related option overlay strategy and/or derivative instruments in implementing their respective investment strategies for the Fund. Additionally, the Management Team may seek exposure to these asset classes through investments in exchange-traded funds. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. 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 is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Advisor's Pricing Committee in ----------------------------- (1) Energy Infrastructure Companies are publicly-traded MLPs, MLP affiliates, Canadian income trusts and their successor companies, pipeline companies, utilities, and other companies that are involved in operating or providing services in support of infrastructure assets such as pipeline, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries. Page 19 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) 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. All securities and other assets of the Fund initially expressed in foreign currencies will be converted to U.S. dollars using exchange rates in effect at the time of valuation. The Fund's investments are valued as follows: Corporate bonds, corporate notes, 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 an independent pricing service approved by the Trust'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. Common stocks, preferred stocks, MLPs and other equity securities listed on any national or foreign exchange (excluding 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 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. Forward foreign currency contracts are fair valued at the current day's interpolated foreign exchange rate, as calculated using the current day's spot rate, and the thirty, sixty, ninety, and one-hundred eighty day forward rates provided by an independent pricing service. Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 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 Page 20 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, does not reflect the security's fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from 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. Fair valuation of a debt security will be based on the consideration of all available information, 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 a 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 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 (for corporate debt only); 11) the economic, political and social prospects/developments of the country of issue and the assessment of the country's government leaders/officials (for sovereign debt only) 12) the prospects for the issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); and 13) other relevant factors. Fair valuation of an equity security will be based on the consideration of all available information, 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 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 Because foreign markets may be open on different days than the days during which investors may transact in the shares of the 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 the 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. 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: 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). Page 21 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) 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 the Fund's investments as of April 30, 2016, is included with the 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 is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method. Distributions received from the Fund's investments in MLPs generally are comprised of return of capital and investment income. The 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 the 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 is not known until after the REITs' fiscal year end. The Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by the Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude. C. FORWARD FOREIGN CURRENCY CONTRACTS The Fund is subject to foreign currency risk in the normal course of pursuing its investment objectives. Forward foreign currency contracts are agreements between two parties ("Counterparties") to exchange one currency for another at a future date and at a specified price. The Fund uses forward foreign currency contracts to facilitate transactions in foreign securities and to manage the Fund's foreign currency exposure. These contracts are valued daily, and the Fund's net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in "Unrealized appreciation (depreciation) on forward foreign currency contracts" on the Statement of Assets and Liabilities. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or the cost of) the closing transaction and the Fund's basis in the contract. This realized gain or loss is included in "Net realized gain (loss) on forward foreign currency contracts" on the Statement of Operations. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movement in currency and securities values and interest rates. Due to the risks, the Fund could incur losses in excess of the net unrealized value shown on the forward foreign currency contracts table in the Portfolio of Investments. In the event of default by the Counterparty, the Fund will provide notice to the Counterparty of the Fund's intent to convert the currency held by the Fund into the currency that the Counterparty agreed to exchange with the Fund. If a Counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Fund may obtain only limited recovery or may obtain no recovery in such circumstances. As of April 30, 2016, the Fund had no open forward foreign currency contracts. D. FUTURES CONTRACTS The Fund purchases or sells (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in "Net realized gain (loss) on futures contracts" on the Statement of Operations. Page 22 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) 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 contacts 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. As of April 30, 2016, the Fund had no open futures contracts. E. OPTIONS CONTRACTS In the normal course of pursuing its investment objective, the Fund may invest up to 20% of its net assets in derivative instruments in connection with hedging strategies. The Fund may invest in exchange-listed futures contracts, exchange-listed options, exchange-listed options on futures contracts, and exchange-listed stock index options. The Fund may purchase (buy) or write (sell) put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures contract may be closed out by an offsetting purchase or sale of a futures option of the same series. Options are marked-to-market daily and their value is affected by changes in the value of the underlying security, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying securities, and the remaining time to the option's expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or the trading volume diminishes. The Fund uses options on futures contracts in connection with hedging strategies. Generally, these strategies are applied under the same market and market sector conditions in which the Fund uses put and call options on securities or indices. The purchase of put options on futures contracts is analogous to the purchase of puts on securities or indices so as to hedge the Fund's securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities which are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund's holdings of securities. If the price when the option is exercised is above the exercise price, however, the Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Fund intends to acquire. Realized gains and losses on purchased options are included in "Net realized gain (loss) on investments" on the Statement of Operations. The Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by the Fund. The Fund will pledge in a segregated account at the Fund's custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be pledged in the segregated account whenever the total value of the pledged assets falls below the amount due on the underlying obligation. The risks associated with the use of options on future contracts include the risk that the Fund may close out its position as a writer of an option only if a liquid secondary market exists for such options, which cannot be assured. The Fund's successful use of options on futures contracts depends on the Advisor's ability to correctly predict the movement in prices on futures contracts and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to option. F. FOREIGN CURRENCY The books and records of the Fund 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 Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) result from changes in foreign currency exchange rates have been included in "Net change in unrealized appreciation (depreciation) on foreign currency translation" on the Statement 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 Statement 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 is included in "Net realized gain (loss) on foreign currency trasactions" on the Statement of Operations. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase settlement date and subsequent sale trade date for fixed-income securities is included in "Net realized gain (loss) on investments" on the Statement of Operations. G. INTEREST-ONLY SECURITIES An interest-only security ("IO Security") is the interest-only portion of a mortgage-backed security that receives some or all of the interest portion of the underlying mortgage-backed security and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due to the IO Security. IO Securities are sold at a deep discount to their notional principal amount. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of an IO Security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of an IO Security will rise. These securities, if any, are identified on the Portfolio of Investments. H. PRINCIPAL-ONLY SECURITIES A principal-only security ("PO Security") is the principal-only portion of a mortgage-backed security that does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO Security will rise. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO Security will fall. These securities, if any, are identified on the Portfolio of Investments. I. 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-backed 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 IO Security and all of the principal is distributed to holders of another type of security known as a PO Security. These securities, if any, are identified on the Portfolio of Investments. J. AFFILIATED TRANSACTIONS The Fund invests in securities of affiliated funds. Dividend income and realized gains and losses, and change in appreciation (depreciation) from affiliated funds are presented on the Statement of Operations. The Fund's investment performance and risks are directly related to the investment performance and risks of the affiliated funds. Amounts related to these investments in the Fund's Portfolio of Investments at April 30, 2016, and for the six months ended are as follows: SHARE ACTIVITY ---------------------------------------------------- BALANCE AT BALANCE AT VALUE AT DIVIDEND REALIZED SECURITY NAME 10/31/15 PURCHASES SALES 4/30/16 4/30/16 INCOME GAIN (LOSS) ------------------------------------------------------------------------------------------------------------------------------ First Trust Emerging Markets Local Currency Bond ETF 6,600 16,100 (5,600) 17,100 $ 730,170 $ 19,318 $ (6,669) First Trust Low Duration Opportunities ETF -- 2,603 (2,603) -- -- -- 526 First Trust Preferred Securities and Income ETF 166,265 -- (89,354) 76,911 1,454,387 80,282 (18,353) First Trust Tactical High Yield ETF 67,818 4,176 (16,109) 55,885 2,679,686 80,407 (63,460) --------------------------------------- $ 4,864,243 $ 180,007 $ (87,956) ======================================= Page 24 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) K. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually. Distributions from net investment income and realized capital gains are determined in accordance with 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 significantly modified 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 time in the future. The tax character of distributions paid during the fiscal year ended October 31, 2015 was as follows: Distributions paid from: Ordinary income................................. $ 559,024 Capital gain.................................... -- Return of capital............................... 208,980 As of October 31, 2015, the components of distributable earnings and net assets on a tax basis for the Fund were as follows: Undistributed ordinary income................... $ (842) Accumulated capital and other losses............ (365,713) Net unrealized appreciation (depreciation)...... (321,690) L. 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, 2015, the Fund had $365,713 of non-expiring capital loss carryforwards for federal income tax purposes. 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, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2014 and 2015 remain open to federal and state audit. As of April 30, 2016, 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. M. 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 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 supervising the selection and ongoing monitoring of the securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) The Fund and First Trust have retained the Sub-Advisors to provide recommendations to the Advisor regarding the selection and on-going monitoring of the securities in the Fund's investment portfolio. First Trust executes all transactions on behalf of the Fund, with the exception of the securities that are selected by FTGP. EIP, an affiliate of First Trust, provides recommendations regarding the selection of MLP securities for the Fund's investment portfolio and provides ongoing monitoring of the MLP securities, MLP affiliate and energy infrastructure securities in the Fund's investment portfolio selected by EIP. EIP exercises discretion only with respect to assets of the Fund allocated to EIP by the Advisor. FTGP, an affiliate of First Trust, selects international sovereign debt securities for the Fund's investment portfolio and provides ongoing monitoring of the international sovereign debt securities in the Fund's investment portfolio selected by FTGP. RBA provides recommendations regarding longer term investment strategies that combine top-down, macroeconomic analysis and quantitatively-driven portfolio construction. Stonebridge, an affiliate of First Trust, provides recommendations regarding the selection and ongoing monitoring of the preferred and hybrid securities in the Fund's investment portfolio. Pursuant to the Investment Management Agreement between the Trust and Advisor, First Trust will supervise the Sub-Advisors and their management of the investment of the Fund's assets and will pay EIP, FTGP, RBA and Stonebridge for their services as the Fund's sub-advisors. First Trust will also be responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses with the exception of those attributable to affiliated Funds, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.85% of its average daily net assets. Pursuant to a contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided, that, the investment companies are advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Trust's Board of Trustees or (ii) the termination of the Fund's management agreement with First Trust. First Trust does not have the right to recover the fees waived that are attributable to acquired fund fees and expenses on the shares of investment companies advised by First Trust. During the six months ended April 30, 2016, the Advisor waived fees of $27,304. During the year ended October 31, 2015, the Fund received a payment from the Advisor of $23,478 in connection with a trade error. 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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, or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen will rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES The cost of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016, were $326,101 and $7,235,100, respectively. The proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016 were $267,386 and $12,017,490, respectively. For the six months ended April 30, 2016, the Fund had no in-kind transactions.

Page 27 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant'). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. The Fund's Creation Units are generally issued and redeemed for cash. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 7. BORROWINGS The Trust on behalf of the Fund, along with First Trust Series Fund and First Trust Variable Insurance Trust, entered into a $135 million Credit Agreement (the "BNYM Line of Credit") with BNYM, to be a liquidity backstop during periods of high redemption volume. A commitment fee of 0.15% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loan is charged by BNYM, which First Trust allocates amongst the funds that have access to the BNYM Line of Credit. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings during the six months ended April 30, 2016. 8. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 9. INDEMNIFICATION The Trust, on behalf of the Fund, has a variety of indemnification obligations under contracts with its service providers. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Information regarding the operation of the PRR may be obtained by calling (800) SEC-0330. RISK CONSIDERATIONS PRINCIPAL RISKS You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objectives will be achieved. CASH TRANSACTIONS RISK: The Fund will, under most circumstances, effect a portion of creations and redemptions for cash, rather than in kind securities. As a result, an investment in the Fund may be less tax efficient than an investment in an ETF that effects its creations and redemption for in kind securities. Because the Fund may effect a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses, and may also result in higher brokerage costs. COVERED CALL RISK. The Fund may invest in covered call options. Covered call risk is the risk that the Fund will forgo, during the option's life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but has retained the risk of loss should the price of the underlying security decline. In addition, as the Fund writes covered calls over more of its portfolio, its ability to benefit from capital appreciation becomes more limited. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. 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. CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund's investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

The use of options and other derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivatives. These risks are heightened when the 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. ENERGY INFRASTRUCTURE COMPANIES RISK. Energy Infrastructure Companies may be directly affected by energy commodity prices, especially those companies that own the underlying energy commodity. A decrease in the production or availability of natural gas, natural gas liquids, crude oil, coal or other energy commodities or a decrease in the volume of such commodities available for transportation, processing, storage or distribution may adversely impact the financial performance of Energy Infrastructure Companies. Energy Infrastructure Companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of Energy Infrastructure Companies. Natural disasters, such as hurricanes in the Gulf of Mexico, also may impact Energy Infrastructure Companies. Certain Energy Infrastructure Companies in the utilities industry are subject to imposition of rate caps, increased competition due to deregulation, difficulty in obtaining an adequate return on invested capital or in financing large construction projects, limitations on operations and increased costs and delays attributable to environmental considerations, and the capital market's ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for these companies. Such issuers have been experiencing certain of these problems to varying degrees. EQUITY SECURITIES RISK. The Fund invests in equity securities. The value of the shares will fluctuate with changes in the value of these 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 the current 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 the capital rises and borrowing costs increase. FINANCIAL COMPANIES RISK. The Fund invests in financial companies, including banks, thrifts and their holding companies. Financial companies are especially subject to the adverse effects of economic recession, currency exchange rates, government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets and in commercial and residential real estate loans, and competition from new entrants in their fields of business. FIXED INCOME SECURITIES RISK. An investment in the Fund involves risk associated with an investment in fixed income securities including the risk that certain of the securities in the Fund may not have the benefit of covenants that would prevent the issuer from engaging in capital restructurings or borrowing transactions in connection with corporate acquisitions, leveraged buyouts or restructurings. This limitation could reduce the ability of the issuer to meet its payment obligations and might result in increased credit risk. In addition, certain of the securities may be redeemed or prepaid by the issuer, resulting in lower interest payments received by the Fund and reduced distributions to shareholders. HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, may be highly speculative. These securities are issued by companies that may have limited operating history, narrowly focused operations, and/or other impediments to the timely payment of periodic interest and principal at maturity. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is generally smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be illiquid. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. Page 31 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) INCOME RISK. Income from the Fund's fixed income investments could decline during periods of falling interest rates. INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term investments. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. Mortgage-related securities are particularly subject to the risk that interest rate volatility may adversely impact the valuation and price of such securities. INVESTMENT COMPANIES RISK. The Fund may invest in the shares of other investment companies, and therefore, the Fund's investment performance and risks may be related to the investment performance and risks of the underlying funds. In general, as a shareholder in other investment companies, the Fund bears its ratable share of the underlying fund's expenses, and would be subject to duplicative expenses to the extent the Fund invests in other investment companies. Pursuant to a contractual agreement, the Advisor has agreed to reduce the management fee paid by the Fund by the proportional amount of the acquired fund fees and expenses of the shares of investment companies held by the Fund so that the Fund would not bear the indirect costs of holding them, provided, that the investment companies are advised by the Advisor. LIQUIDITY RISK. The Fund invests a substantial portion of its assets in lower-quality debt issued by companies that are highly leveraged. Lower-quality debt tends to be less liquid than higher-quality debt. Moreover, smaller debt issues tend to be less liquid than larger debt issues. If the economy experiences a sudden downturn, or if the debt markets for such companies become distressed, the Fund may have particular difficulty selling its assets in sufficient amounts, at reasonable prices and in a sufficiently timely manner to raise the cash necessary to meet any potentially heavy redemption requests by Fund shareholders. As of the fourth quarter of 2015, the market for high yield debt has experienced decreased liquidity, and investor perception of increased risk has caused yield spreads to widen. Decreased liquidity may negatively affect the Fund's ability to mitigate risk and meet redemptions. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the Management Teams will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objectives. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall security values could decline generally or could underperform other investments. MLP RISK. An investment in MLP units involves risks which differ from an investment in common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership. In addition, there are certain tax risks associated with an investment in MLP units and conflicts of interest may exist between common unit holders and the general partner, including those arising from incentive distribution payments. In addition, there is the risk that an MLP could be, contrary to its intention, taxed as a corporation, resulting in decreased returns from such MLP. MORTGAGE SECURITIES RISK. The Fund invests in mortgage-related securities, including mortgage-backed securities, which may make the Fund more susceptible to adverse economic, political or regulatory events that affect the value of real estate. Changes in local, state and federal policies could negatively impact the mortgage-related securities market, which include various government initiated and sponsored homeowner assistance programs and eminent domain issues. Mortgage-related securities may also face liquidity issues when the Fund seeks to sell such securities, but is unable to find buyers at a bid ask spread to make the transaction feasible. These securities are also subject to the risk that the underlying borrowers may default on their mortgages, resulting in a non-payment of principal and interest. Finally, the mortgage-related securities market may be negatively impacted by regulatory changes including those that are related to the mandate or existence of the government-sponsored enterprises, Fannie Mae, Freddie Mac and Ginnie Mae. Mortgage-related securities are subject to the risk that the rate of mortgage prepayments decreases, which extends the average life of a security and increases the interest rate exposure. NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the Fund is only limited as to the percentage of its assets that may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest Page 32 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST STRATEGIC INCOME ETF (FDIV) APRIL 30, 2016 (UNAUDITED) a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers. NON-U.S. SECURITIES RISK AND EMERGING MARKETS RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards and less government supervision and regulation of exchanges in foreign countries. These risks may be heightened for securities of companies located in, or with significant operations in, emerging market countries. PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and selling portfolio securities to rebalance the Fund's exposure to various market sectors. High portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund's performance to be less than you expect. PREFERRED SECURITIES RISK. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt instruments in a company's capital structure in terms of priority to corporate income, and therefore will be subject to greater credit risk than those debt instruments. Preferred securities are also subject to credit risk, interest rate risk and income risk. SENIOR LOAN RISK. An investment in senior loans subjects the Fund to credit risk, which is heightened for loans in which the Fund invests because companies that issue such loans tend to be highly leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy. The loans are usually rated below investment grade but may also be unrated. An economic downturn would generally lead to a higher non payment rate, and a loan may lose significant market value before a default occurs. Moreover, any specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan's value. Unlike the securities markets, there is no central clearinghouse for loan trades, and the loan market has not established enforceable settlement standards or remedies for failure to settle. Therefore, portfolio transactions in loans may have uncertain settlement time periods. Loans are subject to a number of risks described elsewhere in this prospectus, including liquidity risk and the risk of investing in below investment grade debt instruments. Floating rate loans are subject to prepayment risk. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan. SMALL FUND RISK. The Fund currently has fewer assets than larger funds, and like other relatively smaller funds, large inflows and outflows may impact the Fund's market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. SMALLER COMPANIES RISK. The Fund invests in small and/or mid capitalization companies. Such companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. Page 33 This page intentionally left blank. This page intentionally left blank.

PERFORMANCE AND RISK DISCLOSURE There is no assurance that the Fund will achieve its investment objectives. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in the Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of other risks of investing in the Fund. Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown.

Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost. The Advisor may also periodically provide additional information on Fund performance on the Fund's webpage at http://www.ftportfolios.com. HOW TO READ THIS REPORT This report contains information that may help you evaluate your investment in the Fund.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment for the six months ended April 30, 2016. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) The primary investment objective of the First Trust Low Duration Opportunities ETF (the "Fund") is to generate current income. The Fund's secondary investment objective is capital appreciation. The Fund is an actively managed exchange-traded fund. First Trust Advisors L.P. ("First Trust" or the "Advisor") serves as the advisor. Jim Snyder and Jeremiah Charles are the Fund's portfolio managers and are jointly and primarily responsible for the day-to-day management of the Fund's investment portfolio. The Fund's investment categories are: (i) mortgage-related investments, including mortgage-backed securities that may be, but are not required to be, issued or guaranteed by the U.S. government or its agencies or instrumentalities; (ii) U.S. government securities, including callable agency securities, which give the issuer (the U.S. government agency) the right to redeem the security prior to maturity, and U.S. government inflation-indexed securities; and (iii) high yield debt, commonly referred to as "junk" debt. Although the Fund intends to invest primarily in investment grade securities, the Fund may invest up to 20% of its net assets (including investment borrowings) in securities of any credit quality, including securities that are below investment grade (as described in (iii) above), illiquid securities, and derivative instruments. ------------------------------------------------------------------------------------------------------------------------- PERFORMANCE ------------------------------------------------------------------------------------------------------------------------- AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 6 Months Ended 1 Year Ended Inception (11/4/14) Inception (11/4/14) 4/30/16 4/30/16 to 4/30/16 to 4/30/16 FUND PERFORMANCE NAV 3.50% 4.77% 4.82% 7.25% Market Price 3.85% 4.33% 4.82% 7.24% INDEX PERFORMANCE BofA Merrill Lynch 1-5 Year US Treasury & Agency Index 1.10% 1.57% 1.71% 2.55% ------------------------------------------------------------------------------------------------------------------------- Total returns for the periods since inception are calculated from the inception date of the Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the period indicated. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the 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 the Fund at NAV and Market Price, respectively. 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. 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 index. 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance.

A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO), of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured highest to lowest on a scale that generally ranges from AAA to D for long-term ratings and A-1+ to C for short-term ratings. Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher or a short-term credit rating of A-3 or higher. The credit ratings shown relate to the credit worthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares.

("First Trust" or the "Advisor") is the investment advisor to the First Trust Low Duration Opportunities ETF (the "Fund" or "LMBS"). In this capacity, First Trust is responsible for the selection and ongoing monitoring of the investments in the Fund's portfolio and certain other services necessary for the management of the portfolio.

PORTFOLIO MANAGEMENT TEAM JEREMIAH CHARLES - VICE PRESIDENT, PORTFOLIO MANAGER JIM SNYDER - VICE PRESIDENT, PORTFOLIO MANAGER Page 5 FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust Low Duration Opportunities ETF (the "Fund"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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, 2016. 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 period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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.

At April 30, 2016, securities noted as such amounted to $1,537,728 or 4.3% of net assets. (d) Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be illiquid by the Advisor. (e) Step-up security. A security where the coupon increases or steps up at a predetermined date. The interest rate shown reflects the rate in effect at April 30, 2016.

See Notes to Financial Statements Page 21 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) 1. 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 eight funds that are offering shares. This report covers the First Trust Low Duration Opportunities ETF (the "Fund"), which trades under the ticker "LMBS" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are generally issued and redeemed for cash, and in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is an actively managed exchange-traded fund ("ETF"). The Fund's primary investment objective is to generate current income. The Fund's secondary investment objective is capital appreciation. The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets (including investment borrowings) in mortgage-related debt securities and other mortgage-related instruments (collectively, "Mortgage-Related Investments"). The Fund normally expects to invest in Mortgage-Related Investments tied to residential and commercial mortgages. Mortgage-Related Investments include residential mortgage-backed securities, commercial mortgage-backed securities, stripped mortgage-backed securities, collateralized mortgage obligations and real estate mortgage investment conduits. The Fund may also invest in investment companies, such as ETFs, that invest primarily in Mortgage-Related Investments. The Fund will limit its investments in Mortgage-Related Investments that are not issued or guaranteed by Government Entities to 20% of its net assets (including investment borrowings). 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, First Trust Advisors L.P. ("First Trust" or the "Advisor"). The Fund may also invest in to-be-announced transactions ("TBA Transactions"). Further, the Fund may enter into short sales as part of its overall portfolio management strategies or to offset a potential decline in the value of a security; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets (including investment borrowings). Although the Fund intends to invest primarily in investment grade securities, the Fund may invest up to 20% of its net assets (including investment borrowings) in securities of any credit quality, including securities that are below investment grade, which are also known as high yield securities, or commonly referred to as "junk" bonds, or unrated securities that have not been judged by the Advisor to be of comparable quality to rated investment grade securities. In the case of a split rating between one or more of the nationally recognized statistical rating organizations, the Fund will consider the highest rating. Under normal market conditions, the Fund targets an estimated effective duration of three years or less. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 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. 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 is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Advisor's Pricing Committee, in accordance with valuation procedures adopted by the 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. The Fund's investments are valued as follows: Page 22 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) Corporate bonds, corporate notes, 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 an independent pricing service approved by the Trust'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. 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. Common stocks and other equity securities listed on any national or foreign exchange (excluding 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. Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 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 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 a security; 4) the financial statements of the issuer; Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) 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 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 (for corporate debt only); 11) the prospects for the issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); 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: 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 the Fund's investments as of April 30, 2016, is included with the 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 is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method. The Fund invests in interest-only securities. For these securities, if there is a change in the estimated cash flows, based on an evaluation of current information, then the estimated yield is adjusted. Additionally, if the evaluation of current information indicates a permanent impairment of the security, the cost basis of the security is written down and a loss is recognized. Debt obligations may be placed on non-accrual status and the related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured. Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At April 30, 2016, the Fund had no when-issued, delayed-delivery or forward purchase commitments. C. FUTURES CONTRACTS The Fund purchases or sells (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Page 24 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) 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" 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 contacts are marked-to-market daily with the change in value recognized as a component of "Net change in unrealized appreciation (depreciation) on futures" 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. D. OPTIONS CONTRACTS In the normal course of pursuing its investment objective, the Fund may invest up to 20% of its net assets in derivative instruments in connection with hedging strategies. The Fund may invest in exchange-listed options on U.S. Treasury securities, exchange-listed options on U.S. Treasury futures contracts and exchange-listed U.S. Treasury futures contracts. The Fund uses derivative instruments primarily to hedge interest rate risk, actively manage interest rate exposure, hedge foreign currency risk and actively manage foreign currency exposure. The primary risk exposure is interest rate risk. The Fund may purchase (buy) or write (sell) put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option contract may be closed out by an offsetting purchase or sale of a futures option of the same series. Options are marked-to-market daily and their value is affected by changes in the value of the underlying security, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying securities, and the remaining time to the option's expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or the trading volume diminishes. The Fund uses options on futures contracts in connection with hedging strategies. Generally, these strategies are applied under the same market and market sector conditions in which the Fund uses put and call options on securities or indices. The purchase of put options on futures contracts is analogous to the purchase of puts on securities or indices so as to hedge the Fund's securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities which are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund's holdings of securities. If the price when the option is exercised is above the exercise price, however, the Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Fund intends to acquire. The Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by the Fund. The Fund will pledge in a segregated account at the Fund's custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be pledged in the segregated account whenever the total value of the pledged assets falls below the amount due on the underlying obligation. The risks associated with the use of options on future contracts include the risk that the Fund may close out its position as a writer of an option only if a liquid secondary market exists for such options, which cannot be assured. The Fund's successful use of options on futures contracts depends on the Advisor's ability to correctly predict the movement in prices on futures contracts and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to option. Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) E. INTEREST-ONLY SECURITIES An interest-only security ("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. F. PRINCIPAL-ONLY SECURITIES A principal-only security ("PO Security") is the principal-only portion of a mortgage-backed security that does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO Security will rise. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO Security will fall. These securities, if any, are identified on the Portfolio of Investments. G. 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-backed 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 IO Security and all of the principal is distributed to holders of another type of security known as a PO Security. These securities, if any, are identified on the Portfolio of Investments. H. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least annually. Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom the shares were purchased makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker. Distributions from net investment income and realized capital gains are determined in accordance with 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 time in the future. The tax character of distributions paid during the fiscal period ended October 31, 2015, was as follows: Distributions paid from: Ordinary income....................................... $ 159,003 Capital gain.......................................... -- Return of capital..................................... -- As of October 31, 2015, the components of distributable earnings and net assets on a tax basis for the Fund were as follows: Undistributed ordinary income......................... $ 15,304 Accumulated capital and other losses.................. (74,009) Net unrealized appreciation (depreciation)............ 110,496 I. INCOME TAXES The Fund intends 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. Page 26 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) 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, 2015, the Fund had $66,589 of non-expiring capital loss carryforwards for federal income tax purposes. 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 period ended October 31, 2015, the Fund had no net ordinary losses. The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable year ended 2015 remains open to federal and state audit. As of April 30, 2016, 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. J. 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 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 supervising the selection and ongoing monitoring of the securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund's assets and is responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.65% of its average daily net assets. 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 the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each Fund's net assets. 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 or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen will rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES The cost of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016, were $21,576,510 and $11,804,475, respectively. The proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the six months ended April 30, 2016 were $1,887,882 and $8,612,341, respectively. For the six months ended April 30, 2016, the Fund had no in-kind transactions.

CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund Shares (per Creation Unit Aggregation) and the market value of the Page 28 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. The Fund's Creation Units are generally issued and redeemed for cash. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction Fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 7. BORROWINGS The Trust on behalf of the Fund, along with First Trust Series Fund and First Trust Variable Insurance Trust, has a $135 million Credit Agreement (the "BNYM Line of Credit") with BNYM to be a liquidity backstop during periods of high redemption volume. A commitment fee of 0.15% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loan is charged to BNYM, which First Trust will allocate amongst the funds that have access to the BNYM Line of Credit. These fees are reflected on the Statement of Operations in the Commitment Fees line item. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings during the six months ended April 30, 2016. 8. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 9. INDEMNIFICATION The Trust, on behalf of the Fund, 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. 10. SUBSEQUENT EVENTS Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were issued, and has determined there was the following subsequent event: On May 19, 2016, the Fund declared a distribution of $0.1275 per share to shareholders of record on May 24, 2016, payable May 31, 2016. Page 29 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (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 the 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 the Fund's website located at http://www.ftportfolios.com; and (3) on the Securities and Exchange Commission's ("SEC") website at http://www.sec.gov. PORTFOLIO HOLDINGS The Trust files its complete schedule of the Fund's portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Trust's Forms N-Q are available (1) by calling (800) 988-5891; (2) on the Fund's website located at http://www.ftportfolios.com; (3) on the SEC's website at http://www.sec.gov; and (4) for review and copying at the SEC's Public Reference Room ("PRR") in Washington, DC. Information regarding the operation of the PRR may be obtained by calling (800) SEC-0330. RISK CONSIDERATIONS You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objectives will be achieved. CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an exchange-traded fund that effects its creations and redemption for in-kind securities. Because the Fund may effect a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses and may also result in higher brokerage costs. COUNTERPARTY RISK. The Fund bears the risk that the counterparty to a mortgage dollar roll, TBA Transaction, derivative or other contract with a third-party may default on its obligations or otherwise fail to honor its obligations. If a counterparty defaults on its payment obligations the Fund will lose money and the value of an investment in Fund shares may decrease. In addition, the Fund may engage in such investment transactions with a limited number of counterparties. 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. HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and therefore, are considered to be highly speculative. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is generally smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. In general, high yield securities may have a greater risk of default than other types of securities. ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be illiquid. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. INCOME RISK. Income from the Fund's fixed income investments could decline during periods of falling interest rates. INTEREST RATE RISK. Interest rate risk is the risk that the value of the fixed income securities in the Fund will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term investments, which generally have shorter durations, and higher for longer term investments. Mortgage-Related Investments are particularly subject to the risk that interest rate volatility may adversely impact the valuation and price of such securities. LIQUIDITY RISK. The Fund invests a substantial portion of its assets in lower-quality debt issued by companies that are highly leveraged. Lower-quality debt tends to be less liquid than higher-quality debt. Moreover, smaller debt issues tend to be less liquid than larger debt issues. If the economy experiences a sudden downturn, or if the debt markets for such companies become Page 30 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) distressed, the Fund may have particular difficulty selling its assets in sufficient amounts, at reasonable prices and in a sufficiently timely manner to raise the cash necessary to meet any potentially heavy redemption requests by Fund shareholders. As of the fourth quarter of 2015, the market for high yield debt has experienced decreased liquidity, and investor perception of increased risk has caused yield spreads to widen. Decreased liquidity may negatively affect the Fund's ability to mitigate risk and meet redemptions. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the Fund's investment advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objective. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall securities values could decline generally or could underperform other investments. MORTGAGE-RELATED INVESTMENTS RISK. The Fund invests in Mortgage-Related Investments, including mortgage-backed securities, which may make the Fund more susceptible to adverse economic, political or regulatory events that affect the value of real estate. Changes in local, state and federal policies could negatively impact the Mortgage-Related Investments market, which include various government initiated and sponsored homeowner assistance programs and eminent domain issues. Mortgage-Related Investments are subject to the risk that the rate of mortgage prepayments decreases, which extends the average life of a security and increases the interest rate exposure. Mortgage-Related Investments may also face liquidity issues when the Fund seeks to sell such securities, but is unable to find buyers at a bid-ask spread to make the transaction feasible. These securities are also subject to the risk that the underlying borrowers may default on their mortgages, resulting in a non-payment of principal and interest. Finally, the Mortgage-Related Investments market may be negatively impacted by regulatory changes including those that are related to the mandate or existence of the government-sponsored enterprises, FNMA, FHLMC and GNMA. NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the Fund is only limited as to the percentage of its assets that may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers. PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and selling portfolio securities to rebalance the Fund's exposure to various market sectors. High portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund's performance to be less than you expect. PREPAYMENT RISK. Mortgage-Related Investments are subject to pre-payment risk. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan. REPURCHASE AGREEMENT RISK. The Fund's investment in repurchase agreements, including mortgage dollar rolls and TBA Transactions, may be subject to market and credit risk with respect to the collateral securing the agreements. Investments in mortgage dollar rolls also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the agreement term. SHORT SALES RISK. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, which may result in the Fund having to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. In a rising stock market, the Fund's short positions may significantly impact the Fund's overall performance and cause the Fund to underperform traditional long-only equity funds or to sustain losses, particularly in a sharply rising market. The use of short sales may also cause the Fund to have higher expenses than other funds. Because losses on short sales arise from increases in the value of the security sold short, such losses are theoretically unlimited. By contrast, a loss on a long position arises from decreases in the value of the security and is limited by the fact that a security's value cannot go below zero. The Fund's investment Page 31 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS) APRIL 30, 2016 (UNAUDITED) advisor's use of short sales in combination with long positions in the Fund's portfolio in an attempt to improve performance or reduce overall portfolio risk may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund's long securities positions will decline in value at the same time that the value of its short securities positions increase, thereby increasing potential losses to the Fund. In addition, the Fund's short selling strategies may limit its ability to fully benefit from increases in the equity markets. To the extent the Fund invests the proceeds received from selling securities short in additional long positions, the Fund is engaging in a form of leverage. The use of leverage may increase the Fund's exposure to long positions and make any change in the Fund's net asset value greater than it would be without the use of leverage. This could result in increased volatility of returns. SMALL FUND RISK. The Fund currently has fewer assets than larger funds, and like other relatively smaller funds, large inflows and outflows may impact the Fund's market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. U.S. GOVERNMENT AND AGENCY SECURITIES RISK. The Fund may invest in U.S. government obligations. U.S. government obligations include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government or by various instrumentalities, which have been established or sponsored by the U.S. government. U.S. Treasury obligations are backed by the "full faith and credit" of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

Accordingly, you can lose money by investing in the Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of certain other risks of investing in the Fund. Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment since the Fund's inception date of November 3, 2015. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) The First Trust SSI Strategic Convertible Securities ETF (the "Fund") is an actively managed exchange-traded fund that seeks to deliver total return by investing, under normal market conditions, at least 80% of its net assets (including investment borrowings) in a diversified portfolio of U.S. and non-U.S. convertible securities. The shares of the Fund are listed and traded on the Nasdaq Stock Market LLC under the ticker symbol "FCVT." -------------------------------------------------------------------------------- PERFORMANCE -------------------------------------------------------------------------------- CUMULATIVE TOTAL RETURNS Inception (11/3/15) to 4/30/16 FUND PERFORMANCE NAV -1.93% Market Price -1.61% INDEX PERFORMANCE BofA Merrill Lynch All US Convertible Index -3.88% -------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market price returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively. 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. 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 index. 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance. ----------------------------------------------------------- % OF TOTAL SECTOR ALLOCATION INVESTMENTS ----------------------------------------------------------- Information Technology 34.8% Health Care 19.1 Financials 16.6 Consumer Discretionary 9.9 Utilities 4.9 Consumer Staples 3.7 Materials 3.5 Industrials 3.0 Energy 2.4 Telecommunication Services 2.1 ------ Total 100.0% ====== ----------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS INVESTMENTS ----------------------------------------------------------- Wells Fargo & Co., Series L 3.3% Allergan PLC, Series A 3.1 Bank of American Corp., Series L 2.6 Hologic, Inc. 2.6 Priceline Group, Inc./The 2.5 VeriSign, Inc. 2.1 NVIDIA Corp. 2.1 Tesla Motors, Inc. 2.0 Intel Corp. 2.0 Citrix Systems, Inc. 1.9 ------ Total 24.2% ====== Page 2 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) PERFORMANCE OF A $10,000 INITIAL INVESTMENT NOVEMBER 3, 2015 - APRIL 30, 2016 First Trust SSI BofA Merrill Strategic Convertible Lynch All US Securities ETF Convertible Index 11/3/15 $10,000 $10,000 4/30/16 9,807 9,612 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.

NAV THROUGH APRIL 30, 2016 The following Frequency Distribution of Discounts and Premiums charts are provided to show the frequency at which the bid/ask midpoint price for the Fund was at a discount or premium to the daily NAV. The following tables are for comparative purposes only and represent the period November 4, 2015 (commencement of trading) through April 30, 2016. Shareholders may pay more than NAV when they buy Fund shares and receive less than NAV when they sell those shares because shares are bought and sold at current market price.

SSI Investment Management Inc.

OPRE - CFA, PORTFOLIO MANAGER FLORIAN EITNER - CFA, PORTFOLIO MANAGER ETHAN GANZ - ASSOCIATE PORTFOLIO MANAGER Page 4 FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2016 (UNAUDITED) As a shareholder of First Trust SSI Strategic Convertible Securities ETF (the "Fund") you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund 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 (or since inception) and held through the six-month (or shorter) period ended April 30, 2016. 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 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 the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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 EXPENSES PAID EXPENSE RATIO DURING THE PERIOD BEGINNING ENDING BASED ON THE NOVEMBER 3, 2015 (a) ACCOUNT VALUE ACCOUNT VALUE NUMBER OF DAYS TO NOVEMBER 3, 2015 (a) APRIL 30, 2016 IN THE PERIOD APRIL 30, 2016 (b) ---------------------------------------------------------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) Actual $1,000.00 $ 980.70 0.95% $4.63 Hypothetical (5% return before expenses) $1,000.00 $1,020.14 0.95% $4.77 (a) Inception date. (b) Actual expenses are equal to the annualized expense ratio as indicated in the table, multiplied by the average account value over the period (November 3, 2015 through April 30, 2016), and multiplied by 180/366. Hypothetical expenses are assumed for the most recent one-half year period.

Pursuant to procedures adopted by the Trust's Board of Trustees, this security has been determined to be liquid by SSI Investment Management Inc., the sub-advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. At April 30, 2016, securities noted as such amounted to $389,386 or 8.0% of net assets. (b) Zero coupon security. (c) Multi-Step Coupon Bond - Coupon steps up or down at predetermined dates. The interest rate shown reflects the rate in effect at April 30, 2016. (d) Perpetual maturity. (e) Aggregate cost for financial reporting purposes, which approximates the aggregate cost for federal income tax purposes. As of April 30, 2016, the aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $175,745 and the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $189,151. ----------------------------- VALUATION INPUTS A summary of the inputs used to value the Fund's investments as of April 30, 2016 is as follows (see Note 2A - Portfolio Valuation in the Notes to Financial Statements): LEVEL 2 LEVEL 3 TOTAL LEVEL 1 SIGNIFICANT SIGNIFICANT VALUE AT QUOTED OBSERVABLE UNOBSERVABLE 4/30/2016 PRICES INPUTS INPUTS --------------- --------------- --------------- --------------- Convertible Corporate Bonds*....................... $ 3,371,375 $ -- $ 3,371,375 $ -- --------------- --------------- --------------- --------------- Convertible Preferred Securities: Automobiles..................................... 48,056 -- 48,056 -- Food Products .................................. 117,229 87,164 30,065 -- Pharmaceuticals ................................ 233,465 146,068 87,397 -- Other industry categories*...................... 992,336 992,336 -- -- --------------- --------------- --------------- --------------- Total Convertible Preferred Securities............. 1,391,086 1,225,568 165,518 -- --------------- --------------- --------------- --------------- Total Investments.................................. $ 4,762,461 $ 1,225,568 $ 3,536,893 $ -- =============== =============== =============== =============== * See Portfolio of Investments for industry breakout.

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 eight funds that are offering shares. This report covers the First Trust SSI Strategic Convertible Securities ETF (the "Fund"), which trades under the ticker "FCVT" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are issued and redeemed for cash and, in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to seek total return. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a diversified portfolio U.S. and non-U.S. convertible securities. 2. VALUATION AND INVESTMENT PRACTICES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 Fund's net asset value ("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. Domestic debt securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund's NAV is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund's investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), 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. The Fund's investments are valued as follows: Convertible preferred stocks and other equity securities listed on any national or foreign exchange (excluding 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. Convertible corporate bonds, notes and other debt securities are valued on the basis of valuations provided by dealers who make markets in such securities or by an independent pricing service approved by the Trust'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. Page 15 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) 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. Fixed income and other debt securities having a remaining maturity of 60 days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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 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 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 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. Fair valuation of a debt security will be based on the consideration of all available information, 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 security; 4) the financial statements of the issuer; 5) the credit quality and cash flow of the issuer, based on the sub-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 (for corporate debt only); 11) the prospects for the issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); and 12) other relevant factors. Fair valuation of an equity security will be based on the consideration of all available information, 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 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. Page 16 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) 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: 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 the Fund's investments as of April 30, 2016, is included with the 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, is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method. C. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, will be distributed at least annually. Distributions from income and capital gains are determined in accordance with 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 has no impact on net assets or net asset value 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. D. INCOME TAXES The Fund intends 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 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. As of April 30, 2016, 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. E. 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 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 supervising the selection and ongoing monitoring of the securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Page 17 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) The Fund and First Trust have retained SSI Investment Management Inc. ("SSI" or the "Sub-Advisor"), to serve as its investment sub-advisor. In this capacity, SSI is responsible for the selection and on-going monitoring of the securities in the Fund's investment portfolio. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise SSI and its management of the investment of the Fund's assets and will pay SSI for its services as the Fund's sub-advisor. First Trust will also be responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. SSI receives a sub-advisory fee from First Trust. The Trust has multiple service agreements with Brown Brothers Harriman & Co. ("BBH"). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund's assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund. 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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, or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. At a meeting on December 7, 2015, the Board of Trustees accepted Mr. Mark Bradley's resignation from his position as the President and Chief Executive Officer of the Fund, effective December 31, 2015. At the same meeting, the Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and Treasurer of the Trust, to serve as the President and Chief Executive Officer and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as the Treasurer, Chief Financial Officer and Chief Accounting Officer of the Trust. 4. PURCHASES AND SALES OF SECURITIES For the period ended April 30, 2016, the cost of purchases and proceeds from sales of investments, excluding short-term investments and in-kind transactions, for the Fund were $6,226,665 and $1,256,457, respectively. For the period ended April 30, 2016, the Fund had no in-kind transactions. 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund shares (per Creation Unit aggregations) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the creator will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BBH, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction fee is currently $500. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Page 18 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) Authorized Participants redeeming Creation Units must pay to BBH, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $500. The Fund reserves the right to affect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request. 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 7. INDEMNIFICATION The Trust, on behalf of the Fund, 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 to the Fund through the date the financial statements were issued, and has determined there was the following subsequent event: On May 19, 2016, the Fund declared a distribution of $0.03 per share to shareholders of record on May 24, 2016, payable May 31, 2016.

Information regarding the operation of the PRR may be obtained by calling (800) SEC-0330. RISK CONSIDERATIONS You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objective will be achieved. BDC RISK. The Fund may invest in BDCs which may carry risks similar to those of a private equity or venture capital fund. Investments in BDCs may be subject to price volatility and lack of liquidity. Debt securities and preferred securities issued by BDCs may be rated below investment grade (referred to as "junk" bonds), including in the lowest possible rating category, or unrated. Shares of BDCs are not redeemable at the option of the shareholder and they may trade in the market at a discount to their net asset value. Moreover, a shareholder of a BDC will indirectly bear its pro rata share of the fees and expenses incurred by the BDC in which it invests, including advisory fees. The BDCs held by the Fund may employ the use of leverage through borrowings or the issuance of preferred stock. This leverage also subjects a BDC to increased risks, including the likelihood of increased volatility and the possibility that a BDC's common share income will fall if the dividend rate of the preferred shares or the interest rate on any borrowings rises. The loss on a leveraged investment may far exceed the principal amount invested. Moreover, the use of leverage may result in a BDC having to liquidate holdings when it may not be advantageous to do so. Investments in BDCs include risks associated with their holdings of smaller issuers and private companies. A BDC may make investments with a larger amount of risk of volatility and loss of principal than other investment options and may also be highly speculative and aggressive. For example, BDCs may invest in the debt of a company, which involves risk that the company may default on its payments or declare bankruptcy, and many of the debt instruments in which a BDC may invest will not be rated by a credit rating agency and may be below investment grade quality (referred to as "junk" bonds). A BDC's investments are generally less liquid than publicly traded securities and are subject to restrictions on their resale. The illiquidity of a BDC's holdings may make it difficult for the BDC to sell such investments if the need arises, and thus the BDC may be unable to take advantage of market opportunities or it may be forced to sell illiquid securities at a loss if it is required to raise cash for operations. Some BDCs are listed and trade on an exchange and other BDCs are not traded on an exchange and trade only in private transactions. BDCs that are not traded on an exchange may be less liquid than those that are traded on an exchange. An investment in BDCs may result in a complete loss of the investment. CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a significant portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions for in-kind securities. Because the Fund may effect a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A sale of shares may result in capital gains or losses, and may also result in higher brokerage costs. CONVERTIBLE SECURITIES RISK. Convertible securities have characteristics of both equity and debt securities and, as a result, are exposed to certain additional risks. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying equity security or sell it to a third party, which may have an adverse effect on the Fund's ability to achieve its investment objective. The market values of convertible securities tend to decline as interest rates increase. However, a convertible security's market value also tends to reflect the market price of the equity security of the issuing company, particularly when the price of the equity security is greater than the convertible security's conversion price (i.e., the predetermined price or exchange ratio at which the convertible security can be converted or exchanged for the underlying equity security). Convertible securities are also exposed to the risk that an issuer is unable to meet its obligation to make dividend or principal payments when due as a result of changing financial or market conditions. Convertible securities generally offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of their potential for capital appreciation. Moreover, there can be no assurance that convertible securities will provide current income prior to conversion because the issuers of the convertible securities may default on their obligations. Page 20 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) Mandatory convertible securities are a subset of convertible securities. The conversion of such securities is not optional, and the conversion price at maturity is based solely upon the market price of the underlying equity security, which may be significantly less than par or the price (above or below par) paid. Mandatory convertible securities generally are subject to a greater risk of loss of value than securities convertible at the option of the holder. Contingent convertible securities (which generally provide for conversion under certain circumstances) are also a subset of convertible securities. They may have some of the characteristics of high yield bonds (referred to as "junk" bonds), while providing exposure to equity-like losses and volatility. Similar to mandatory convertible securities (and unlike traditional convertible securities), some contingent convertible securities provide for mandatory conversion under certain circumstances. The mandatory conversion might be automatically triggered, for instance, if a company fails to meet the minimum amount of capital described in the security, the company's regulator makes a determination that the security should convert or the company receives specified levels of extraordinary public support. Additionally, contingent convertible securities may contain features that limit an investor's ability to convert the security into the underlying equity security unless certain conditions are met. A typical feature may require that a security be convertible only when the sale price of the underlying common stock exceeds the conversion price by a specified percentage (e.g., the sale price of the common stock is greater than or equal to 130% of the conversion price) for a certain specified period of time (e.g., for at least 20 days during a span of 30 consecutive days in a month), or upon the occurrence of certain other specified conditions. Also, since the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero, and conversion would deepen the subordination of the investor, hence worsening standing in a bankruptcy. Further, some contingent convertible securities have a set stock conversion rate that would cause a reduction in value of the security if the price of the stock is below the conversion price on the conversion date. Additionally, some contingent convertible securities have characteristics designed to absorb losses, where the liquidation value of the security may be adjusted downward to below the original par value or written off entirely under certain circumstances. The write-down of the security's par value may occur automatically and would not entitle holders to institute bankruptcy proceedings against the issuer. In addition, an automatic write-down could result in a reduced income rate if the dividend or interest payment associated with the security is based on the security's par value. Moreover, various contingent convertible securities may contain features that limit an investor's ability to convert the security unless certain conditions are met. The values of certain synthetic convertible securities will respond differently to market fluctuations than a traditional convertible security because such synthetic convertibles are composed of two or more separate securities or instruments, each with its own market value. In addition, if the value of the underlying equity security or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value. Synthetic convertible securities created by other parties generally have economic characteristics similar to those of a traditional convertible security; however, the issuer of the synthetic convertible security assumes the credit risk associated with the investment, rather than the issuer of the underlying equity security into which the instrument is convertible. Therefore, the Fund is subject to the credit risk associated with the counterparty creating the synthetic convertible instrument. Synthetic convertible securities may also be subject to additional liquidity risk and to the risks associated with derivatives. CREDIT RISK. 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. Credit risk may be heightened if the Fund invests in "high yield" or "junk" securities; such securities involve greater risks than investment grade debt securities with similar maturities, including the possibility of dividend or interest deferral, default or bankruptcy, and are regarded as predominantly speculative with respect to the issuer's capacity to pay dividends or interest and repay principal. CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund's investments and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. DEBT SECURITIES RISK. An investment in the Fund involves risk associated with an investment in debt securities including the risk that certain of the securities in the Fund may not have the benefit of covenants that would prevent the issuer from engaging in capital restructurings or borrowing transactions in connection with corporate acquisitions, leveraged buyouts or restructurings. This limitation could reduce the ability of the issuer to meet its payment obligations and might result in increased credit risk. In addition, certain of the securities may be redeemed or prepaid by the issuer, resulting in lower interest payments received by the Fund and reduced distributions to shareholders. Page 21 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert shares into depositary receipts and vice versa. Such restrictions may cause shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. DERIVATIVES RISK. The use of swaps, options, futures contracts, forward contracts and other derivatives can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivatives. These risks are heightened when the Fund's portfolio managers use derivatives to enhance the Fund's return, rather than solely to hedge (or offset) the risk of a position or security held by the Fund. EQUITY SECURITIES RISK. The Fund may hold equity securities in its portfolio through direct investments in equity securities or upon conversion of a convertible security. The value of the Fund's shares will fluctuate with changes in the value of these 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 the current 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 the capital rises and borrowing costs increase. ETNS RISK. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy minus applicable fees. ETNs are subject to credit risk, and the value of the ETN may drop due to a downgrade in the issuer's credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in the applicable interest rates, changes in the issuer's credit rating and economic, legal, political or geographic events that affect the referenced underlying asset. HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings and, therefore, may be highly speculative. These securities are issued by companies that may have limited operating history, narrowly focused operations, and/or other impediments to the timely payment of periodic interest and principal at maturity. If the economy slows down or dips into recession, the issuers of high yield securities may not have sufficient resources to continue making timely payment of periodic interest and principal at maturity. The market for high yield securities is generally smaller and less liquid than that for investment grade securities. High yield securities are generally not listed on a national securities exchange but trade in the over-the-counter markets. Due to the smaller, less liquid market for high yield securities, the bid-offer spread on such securities is generally greater than it is for investment grade securities and the purchase or sale of such securities may take longer to complete. In general, high yield securities may have a greater risk of default than other types of securities. ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be illiquid. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximately the value at which the Fund is carrying the securities on its books. INCOME RISK. Income from the Fund's fixed income investments could decline during periods of falling interest rates. INTEREST RATE RISK. Interest rate risk is the risk that the value of the fixed income securities in the Fund will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term investments and higher for longer term investments. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the sub-advisor of the Fund will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objective. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall securities values could decline generally or could underperform other investments. NEW FUND RISK. The Fund currently has fewer assets than larger funds, and like other relatively new funds, large inflows and outflows may impact the Fund's market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. Also, during the initial invest-up period, the Fund may depart from its principal investment strategies and invest a larger amount or all of its assets in cash equivalents or it may hold cash. Page 22 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers. NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, different legal or accounting standards, and less government supervision and regulation of exchanges in foreign countries. PREFERRED SECURITIES RISK. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt instruments in a company's capital structure in terms of priority to corporate income and therefore will be subject to greater credit risk than those debt instruments. Preferred securities are also subject to credit risk, interest rate risk and income risk. RESTRICTED SECURITIES RISK. Investments in restricted securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase these securities. Illiquid and restricted securities may be difficult to dispose of at the price at which the Fund has valued the securities and at the times when the Fund believes it is desirable to do so. The market price of illiquid and restricted securities generally is more volatile than that of more liquid securities, which may adversely affect the price that the Fund recovers upon the sale of such securities. Investment of the Fund's assets in illiquid and restricted securities may restrict the Fund's ability to take advantage of market opportunities. WARRANTS RISK. The prices of warrants, which entitle the holder to purchase equity securities at specific prices for a certain period of time, do not necessarily move parallel to the prices of the underlying securities and likely fluctuate more than the prices of the underlying securities. Warrants have no voting rights, receive no dividends, and have no rights with respect to the assets of the issuer. ADVISORY AND SUB-ADVISORY AGREEMENTS BOARD CONSIDERATIONS REGARDING APPROVAL OF INVESTMENT MANAGEMENT AND INVESTMENT SUB-ADVISORY AGREEMENTS The Board of Trustees of the First Trust Exchange-Traded Fund IV (the "Trust"), including the Independent Trustees, unanimously approved the Investment Management Agreement (the "Advisory Agreement") with First Trust Advisors L.P. ("First Trust" or the "Advisor") on behalf of the First Trust SSI Strategic Convertible Securities ETF (the "Fund") and the Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement" and together with the Advisory Agreement, the "Agreements") among the Trust, on behalf of the Fund, the Advisor and SSI Investment Management Inc. (the "Sub-Advisor"), for an initial two-year term at a meeting held on January 21, 2015. The Board of Trustees determined that the Agreements are in the best interests of the Fund in light of the extent and quality of services expected to be provided and such other matters as the Board considered to be relevant in the exercise of its reasonable 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. To assist the Board in its evaluation of the Agreements, the Independent Trustees received a separate report from each of the Advisor and the Sub-Advisor in advance of the Board meeting responding to a request for information provided on behalf of the Independent Trustees that, among other things, outlined the services to be provided by the Advisor and the Sub-Advisor to the Fund (including the relevant personnel responsible for these services and their experience); the proposed unitary fee structure for the Fund as compared to fees charged by advisors to other comparable exchange-traded funds ("ETFs"), and as compared to fees charged to other ETFs managed by First Trust; the estimated expenses to be incurred in providing services to the Fund and the potential for economies of scale, if any; financial data on the Advisor and the Sub-Advisor; fall out benefits to First Trust and its affiliate, First Trust Portfolios L.P. ("FTP"); and a summary of the Advisor's compliance program. The Independent Trustees also met separately with their independent legal counsel to discuss the information provided by the Advisor and the Sub-Advisor. The Board applied its business judgment to determine whether the arrangements between the Trust and First Trust and among the Trust, the Advisor and the Sub-Advisor are reasonable business arrangements from the Fund's perspective as well as from the perspective of shareholders. In evaluating whether to approve the Agreements for the Fund, the Board considered the nature, extent and quality of services to be provided by the Advisor and the Sub-Advisor under the Agreements and considered that the Advisor's employees provide management services to other ETFs and to other investment companies in the First Trust fund complex with diligence and care. Page 23 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT) APRIL 30, 2016 (UNAUDITED) The Board considered that the Fund is not designed to track the performance of an index and will employ an advisor/sub-advisor management structure. With respect to the Advisory Agreement, the Board considered that First Trust will be responsible for the overall management and administration of the Fund and reviewed the services to be provided by First Trust to the Fund, including the oversight of the Sub-Advisor. The Board considered the compliance program that had been developed by First Trust and considered it includes a robust program for monitoring the Sub-Advisor's compliance with the 1940 Act and the Fund's investment objective and policies. It also considered the efforts expended by First Trust in organizing the Trust and in arranging for other entities to provide services to the Fund. With respect to the Sub-Advisory Agreement, the Board noted the background and experience of the Sub-Advisor's portfolio management team and the Sub-Advisor's investment style. At the meeting, the Trustees received a presentation from five representatives of the Sub-Advisor, including the Chief Executive Officer, the President, the Chief Investment Officer and a portfolio manager, and were able to ask questions about the Sub-Advisor and the Sub-Advisor's proposed investment strategies for the Fund. The Sub-Advisor's representatives stated that the Sub-Advisor provides sub-advisory services to a registered investment company and thus has familiarity with the requirements of the 1940 Act. Since the Fund had yet to commence investment operations, the Board could not consider the historical investment performance of the Fund. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of services to be provided to the Fund by the Advisor and the Sub-Advisor under the Agreements are expected to be satisfactory. The Board reviewed information regarding the proposed unitary fee structure for the Fund. The Board noted that under the Fund's unitary fee arrangement, the Fund would pay First Trust a fee equal to an annual rate of 0.95% of its average daily net assets. The Board also noted that, from the unitary fee, First Trust would pay the Sub-Advisor a sub-advisory fee equal to one half of any remaining monthly unitary fee paid to the Advisor after the Fund's average expenses accrued during the most recent twelve months are subtracted from the unitary fee for that month. The Board also noted that First Trust would be responsible for the Fund's ordinary operating expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, and license fees, if any, but excluding the fee payments under the Advisory Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions such as dividend and distribution expenses from securities sold short and/or other investment-related costs, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Board reviewed information provided by Management Practice Inc. ("MPI"), an independent source, as well as by First Trust, for the Fund on the advisory fees and expense ratios of other comparable ETFs, but also noted First Trust's statements about the limitations on the comparability of the peer groups with the Fund, including that not all of the ETFs in the MPI peer group are actively managed. The Board also considered supplemental information provided by First Trust on advisory fees and expense ratios of all actively managed ETFs as of a recent date. The Board noted that the Fund's expense ratio under its proposed unitary fee was above the median expense ratio of its MPI peer group. The Board compared the Fund's unitary fee to the total expense ratios (after fee waivers and/or expense reimbursements, if any) of other First Trust ETFs, including First Trust ETFs that pay a unitary fee, and to the advisory fees charged by First Trust to other advisory clients, noting the Advisor's statement that it provides services to First Trust Tactical High Yield ETF and First Trust Senior Loan Fund, both of which are actively managed ETFs that invest in below grade securities, the former of which also pays an annual unitary fee of 0.95%. In light of the information considered and the nature, extent and quality of services expected to be provided to the Fund under the Agreements, the Board determined that the proposed unitary fee for the Fund was fair and reasonable. The Board noted that the proposed unitary fee for the Fund was not structured to pass the benefits of any economies of scale on to shareholders as the Fund's assets grow. The Board noted that any reduction in fixed costs associated with the management of the Fund would benefit the Advisor and the Sub-Advisor, but that a unitary fee structure provides a level of certainty in expenses for the Fund. The Board noted that First Trust has continued to invest in personnel and infrastructure for the First Trust fund complex. The Board took the costs to be borne by First Trust in connection with its services to be performed for the Fund under the Advisory Agreement into consideration and noted that First Trust was unable to estimate the profitability of the Advisory Agreement to First Trust. The Board also considered that the Sub-Advisor was unable to estimate the profitability of the Sub-Advisory Agreement to the Sub-Advisor and that the Sub-Advisor would be paid by the Advisor from the unitary fee. The Board considered that the sub-advisory fee rate was negotiated at arm's length between the Advisor and the Sub-Advisor, an unaffiliated third party, and the fee is a net fee payable after the Fund's ordinary operating expenses are paid. The Board considered fall-out benefits described by the Advisor that may be realized from its and FTP's relationship with the Fund. The Board considered fall out benefits described by the Sub-Adviser that may be realized from its relationship with the Fund, including from soft-dollar arrangements, and the Advisor's proposal that the Sub-Advisor also serve as sub-advisor to a new closed-end fund being organized by the Advisor. The Board also considered the Advisor's statement that it or an affiliate may make an investment in the Sub-Advisor. Based on all the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreements are fair and reasonable and that the approval of the Agreements are in the best interests of the Fund. No single factor was determinative in the Board's analysis. Page 24 FIRST TRUST First Trust Exchange-Traded Fund IV INVESTMENT ADVISOR First Trust Advisors L.P. 120 E.

PERFORMANCE AND RISK DISCLOSURE There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in the Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of certain other risks of investing in the Fund. Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit http://www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost. The Advisor may also periodically provide additional information on Fund performance on the Fund's webpage at http:www.ftportfolios.com.

It is important to keep in mind that the opinions expressed by the personnel of the Advisor and/or Sub-Advisor are just that: informed opinions.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the semi-annual report which contains detailed information about your investment since the Fund's inception date of November 11, 2015. Additionally, First Trust compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices, and second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%. First Trust believes that having a long-term investment horizon and being invested in quality products can help you reach your goals, despite how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investments each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 1 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) First Trust Heitman Global Prime Real Estate ETF (the "Fund") is an actively managed exchange-traded fund that seeks to deliver long-term total return by investing, under normal market conditions, at least 80% of its assets in U.S. and non-U.S. exchange-traded real estate securities, which includes real estate investment trusts ("REITs"), real estate operating companies ("REOCs") and common stocks or depositary receipts of companies primarily engaged in the real estate industry. Accordingly, the Fund is concentrated in REITs and/or real estate management and development companies (including REOCs), sub-industries of the real estate industry group. The Fund will not invest directly in real estate. Shares of the Fund are listed on the NYSE Arca, Inc. under the ticker symbol "PRME." -------------------------------------------------------------------------------- PERFORMANCE -------------------------------------------------------------------------------- CUMULATIVE TOTAL RETURNS Inception (11/11/15) to 4/30/16 FUND PERFORMANCE NAV 4.74% Market Price 4.74% INDEX PERFORMANCE FTSE EPRA/NAREIT Developed Index 7.94% -------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of the Fund. "Cumulative Total Returns" represent the total change in value of an investment over the period indicated. The 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market price returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively. 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. 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 index. 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 the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund's past performance is no guarantee of future performance.

This Example is intended to help you understand your ongoing costs of investing in the Fund 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 (or since inception) and held through the six-month (or shorter) period ended April 30, 2016. 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 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 the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the 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 Fund 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 EXPENSES PAID EXPENSE RATIO DURING THE PERIOD BEGINNING ENDING BASED ON THE NOVEMBER 11, 2015 (a) ACCOUNT VALUE ACCOUNT VALUE NUMBER OF DAYS TO NOVEMBER 11, 2015 (a) APRIL 30, 2016 IN THE PERIOD APRIL 30, 2016 (b) ---------------------------------------------------------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) Actual $1,000.00 $1,047.40 0.95% $4.57 Hypothetical (5% return before expenses) $1,000.00 $1,020.14 0.95% $4.77 (a) Inception date. (b) Actual expenses are equal to the annualized expense ratio as indicated in the table, multiplied by the average account value over the period (November 11, 2015 through April 30, 2016), and multiplied by 172/366. Hypothetical expenses are assumed for the most recent one-half year 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 eight funds that are offering shares. This report covers the First Trust Heitman Global Prime Real Estate ETF (the "Fund"), which trades under the ticker "PRME" on the NYSE Arca, Inc. ("NYSE Arca"). Unlike conventional mutual funds, the fund issues and redeems shares on a continuous basis, as net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are issued and redeemed principally in-kind for securities in which the Fund invests or for cash or, in certain circumstances, a combination of both. Except when aggregated in Creation Units, the Fund's shares are not redeemable securities. The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to provide long-term total return. Under normal market conditions, the Fund will seek to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in U.S. and non-U.S. exchange-traded real estate securities, which includes real estate investment trusts ("REITs"), real estate operating companies ("REOCs") and common stocks or depositary receipts of companies primarily engaged in the real estate industry (collectively, "Real Estate Securities"). There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors. 2. SIGNIFICANT ACCOUNTING POLICIES The Fund, which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows accounting and reporting guidance under FASB 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 Fund's net asset value ("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. The Fund's NAV is calculated 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 shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund's investment advisor, First Trust Advisors L.P. (the "Advisor"), 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. The Fund's investments are valued as follows: Common stocks, real estate investment trusts ("REITs") 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 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 (the "1933 Act")) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a Page 12 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) 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 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 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 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. 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: 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 the Fund's investments as of April 30, 2016, is included with the Fund's Portfolio of Investments. Page 13 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) 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 REITs may be comprised of return of capital, capital gains and income. The actual character of the amounts received during the year is 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 Fund 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 Statement 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 Statement 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 dividend received and is included in "Net realized gain (loss) on foreign currency transactions" on the Statement 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 Statement of Operations. D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid quarterly, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, will be distributed at least annually. Distributions from income and capital gains are determined in accordance with 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 has no impact on net assets or net asset value 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. E. INCOME TAXES The Fund intends 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 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. As of April 30, 2016, 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. 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 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 supervising the selection and ongoing monitoring of the securities in the Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. Page 14 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) The Fund and First Trust have retained Heitman Real Estate Securities LLC ("Heitman" or the "Sub-Advisor"), an affiliate of First Trust, to serve as its investment sub-advisor and Heitman International Real Estate Securities HK Limited and Heitman International Real Estate Securities GmbH (the "Sub-Sub-Advisors") to serve as the investment sub-sub-advisors. In this capacity, the Sub-Advisor is responsible for the selection and on-going monitoring of the securities in the Fund's investment portfolio and overseeing the Sub-Sub-Advisors. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise Heitman and its management of the investment of the Fund's assets and will pay Heitman for its services as the Fund's sub-advisor. The Sub-Sub-Advisors' fees are paid by the Sub-Advisor out of the Sub-Advisor management fee. First Trust will also be responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. The Trust has multiple service agreements with Brown Brothers Harriman & Co. ("BBH"). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund's assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund's securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund. At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark Bradley's resignation from his position as the President and Chief Executive Officer of the Trust, effective December 31, 2015. At the same meeting, the Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and Treasurer of the Trust, to serve as the President and Chief Executive Officer, and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as the Treasurer, Chief Financial Officer and Chief Accounting Officer of the Trust. 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 based on net assets. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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, or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2016, the cost of purchases and proceeds from sales of investments, excluding short-term investments and in-kind transactions, were $734,927 and $719,297, respectively. For the six months ended April 30, 2016, the cost of in-kind purchases was $1,996,815. 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). In order to purchase Creation Units of the Fund, an Authorized Participant must deposit (i) a designated portfolio of equity securities determined by First Trust (the "Deposit Securities") and generally make or receive a cash payment referred to as the "Cash Component," which is an amount equal to the difference between the NAV of the Fund shares (per Creation Unit aggregations) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the creator will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BBH, as transfer agent, a creation transaction fee (the "Creation Transaction Fee") regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Creation Transaction fee is currently $700. The price for each Creation Unit will equal the daily NAV per share times the number of shares in a Creation Unit plus the fees described above and, if applicable, Page 15 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) any operational processing and brokerage costs, transfer fees or stamp taxes. When the Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including 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 such Deposit Securities and/or substitute securities. Authorized Participants redeeming Creation Units must pay to BBH, as transfer agent, a redemption transaction fee (the "Redemption Transaction Fee"), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund's portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee is currently $700. The Fund reserves the right to affect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, the Fund may, in its discretion, reject any such request 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2017. 7. INDEMNIFICATION The Trust, on behalf of the Fund, has a variety of indemnification obligations under contracts with its service providers. The Fund's maximum exposure under these arrangements is unknown. However, the Fund 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 to the Fund through the date the financial statements were issued, and has determined there were no subsequent events requiting recognition or disclosure in the financial statements.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objective will be achieved. ASIA INVESTMENT RISK. The Fund invests, in part, in securities issued by companies operating in Asia, and is therefore subject to certain risks associated specifically with Asia. For example, some of the currencies of these countries, including China, have experienced devaluations relative to the U.S. dollar, and adjustments have been made periodically in certain of such currencies. Certain countries, such as Indonesia, face serious exchange constraints. Jurisdictional disputes also exist, for example, between South Korea and North Korea. The Tokyo stock market, as measured by the Tokyo Stock Price Index, has been volatile. Declines in the Tokyo stock market have made the country's banks and financial institutions vulnerable. Furthermore, the natural disasters that have impacted Japan and the ongoing recovery efforts have had a negative effect on Japan's economy, and may continue to do so. CONCENTRATION RISK. The Fund is concentrated in REITs and/or real estate management and development companies. A fund concentrated in a single sector, industry or group of industries is likely to present more risks than a fund that is broadly diversified over several industries or sectors. Compared to the broad market, an individual industry or sector may be more strongly affected by changes in the economic climate, broad market shifts, moves in a particular dominant stock, or regulatory changes. CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund's investments and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert shares into depositary receipts and vice versa. Such restrictions may cause shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. EMERGING MARKETS RISK. Investments in securities of issuers located in emerging market countries are considered speculative. Heightened risks of investing in emerging markets securities include: (i) smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; (ii) significant price volatility; (iii) restrictions on foreign investment; and (iv) possible repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. The currencies of emerging market countries may experience significant declines against the U.S. dollar, and devaluation may occur subsequent to investments in these currencies by the Fund. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Page 17 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) EQUITY SECURITIES RISK. Because the Fund invests in equity securities, the value of the Fund's shares will fluctuate with changes in the value of these 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 current 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. EUROPE INVESTMENT RISK. The Fund invests in securities issued by companies operating in Europe. The Fund is therefore subject to certain risks associated specifically with Europe. A significant number of countries in Europe are member states in the European Union, and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. Furthermore, the European sovereign debt crisis and the related austerity measures in certain countries have had, and continue to have, a significant negative impact on the economies of certain European countries and their future economic outlooks. INTEREST RATE RISK. The Fund is subject to interest rate risk. Increases in interest rates typically coincide with higher investor required returns and can lower the present value of a REIT's future earnings stream if not met with a commensurate increase in growth. MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the portfolio managers of the Fund will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objective. MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Shares are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Overall Fund share values could decline generally or could underperform other investments. NEW FUND RISK. The Fund currently has fewer assets than larger funds, and like other relatively new funds, large inflows and outflows may impact the Fund's market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers. NON-U.S. SECURITIES RISK. The Fund may invest in securities of non-U.S. 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, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, different legal or accounting standards, and less government supervision and regulation of exchanges in foreign countries. REAL ESTATE INVESTMENT RISK. The Fund invests in companies in the real estate industry, including REITs and REOCs. Therefore, the Fund is subject to the risks associated with investing in real estate, which may include, but are not limited to, fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in competition, property taxes, capital expenditures or operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate industry. REIT INVESTMENT RISK. In addition to risks related to investments in real estate generally, investing in REITs involves certain other risks related to their structure and focus, which include, but are not limited to, dependency upon management skills, limited diversification, the risks of locating and managing financing for projects, heavy cash flow dependency, possible default by borrowers, the costs and potential losses of self-liquidation of one or more holdings, the risk of a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages, changes in neighborhood values and appeal to purchases, the possibility of failing to maintain exemptions from registration under the 1940 Act and, in many cases, relatively small market capitalization, which may result in less market liquidity and greater price volatility. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities.

("First Trust" or the "Advisor") on behalf of the First Trust Heitman Global Prime Real Estate ETF (the "Fund"), the Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement") among the Trust, on behalf of the Fund, the Advisor and Heitman Real Estate Securities LLC (the "Sub-Advisor"), and the Investment Sub-Sub-Advisory Agreements (the "Sub-Sub-Advisory Agreements") among the Trust, on behalf of the Fund, the Advisor, the Sub-Advisor and each of Heitman International Real Estate Securities HK Limited ("Heitman HK") and Heitman International Real Estate Securities GmbH ("Heitman GmbH" and together with Heitman HK, the "Sub-Sub-Advisors"). The Sub-Sub-Advisory Agreements, the Sub-Advisory Agreement and the Advisory Agreement are collectively referred to as the "Agreements." The Agreements were approved for an initial two-year term at a meeting held on March 8-9, 2015. The Board of Trustees determined that the Agreements are in the best interests of the Fund in light of the extent and quality of services expected to be provided and such other matters as the Board considered to be relevant in the exercise of its reasonable 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. To assist the Board in its evaluation of the Agreements, the Independent Trustees received a separate report from each of the Advisor and the Sub-Advisor (including information on the Sub-Sub-Advisors) in advance of the Board meeting responding to a request for information provided on behalf of the Independent Trustees that, among other things, outlined the services to be provided by the Advisor, the Sub-Advisor and the Sub-Sub-Advisors to the Fund (including the relevant personnel responsible for these services and their experience); the proposed unitary fee structure for the Fund as compared to fees charged by advisors to other comparable exchange-traded funds ("ETFs") and global REIT mutual funds, and as compared to fees charged to other ETFs managed by First Trust; the estimated expenses to be incurred in providing services to the Fund and the potential for economies of scale, if any; financial data on the Advisor, the Sub-Advisor and the Sub-Sub-Advisors; fall out benefits to First Trust and its affiliate, First Trust Portfolios L.P. ("FTP") and to the Sub-Advisor and Sub-Sub-Advisors; and a summary of the Advisor's and the Sub-Advisor's compliance program (which included the Sub-Sub-Advisors). The Independent Trustees also met separately with their independent legal counsel to discuss the information provided by the Advisor, the Sub-Advisor and the Sub-Sub-Advisors. The Board applied its business judgment to determine whether the arrangements between the Trust and First Trust; among the Trust, the Advisor and the Sub-Advisor; and among the Trust, the Advisor, the Sub-Advisor and each of Heitman HK and Heitman GmbH are reasonable business arrangements from the Fund's perspective as well as from the perspective of shareholders. In evaluating whether to approve the Agreements for the Fund, the Board considered the nature, extent and quality of services to be provided by the Advisor, the Sub-Advisor and the Sub-Sub-Advisors under the Agreements and considered that the Advisor's employees provide management services to other ETFs and to other investment companies in the First Trust fund complex with diligence and care. The Board considered that the Fund is not designed to track the performance of an index and will employ an advisor/sub-advisor/sub-sub-advisor management structure. With respect to the Advisory Agreement, the Board considered that First Trust will be responsible for the overall management and administration of the Fund and reviewed the services to be provided by First Trust to the Fund, including the oversight of the Sub-Advisor and the Sub-Sub-Advisors. The Board considered the compliance program that had been developed by First Trust and considered that it includes a robust program for monitoring the Sub-Advisor's and Sub-Sub-Advisors' compliance with the 1940 Act and the Fund's investment objective and policies. It also considered the efforts expended by First Trust in organizing the Trust and in arranging for other entities to provide services to the Fund. With respect to the Sub-Advisory Agreement and Sub-Sub-Advisory Agreements, the Board noted the background and experience of the Sub-Advisor's and Sub-Sub-Advisors' portfolio management teams and the Sub-Advisor's and Sub-Sub-Advisors' investment style. At the meeting, the Trustees received a presentation from representatives of the Sub-Advisor and were able to ask questions about the Sub-Advisor and the Sub-Sub-Advisors and their proposed investment strategies for the Fund. The Sub-Advisor's representatives explained the reason for structuring the sub-advisory relationship with two sub-sub-advisors, noting that both Sub-Sub-Advisors are U.S. registered investment advisors that use the same Chief Compliance Officer as the Sub-Advisor, and that the structure was created so that the Sub-Advisor could achieve best execution by using its affiliates to execute certain portfolio transactions. Since the Fund had yet to commence investment operations, the Board could not consider the historical investment performance of the Fund. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of services to be provided to the Fund by the Advisor, Sub-Advisor and Sub-Sub-Advisors under the Agreements are expected to be satisfactory. Page 19 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME) APRIL 30, 2016 (UNAUDITED) The Board reviewed information regarding the proposed unitary fee structure for the Fund. The Board noted that under the Fund's unitary fee arrangement, the Fund would pay First Trust a fee equal to an annual rate of 0.95% of its average daily net assets. The Board also noted that, from the unitary fee, First Trust would pay the Sub-Advisor a sub-advisory fee equal to one-half of any remaining monthly unitary fee paid to the Advisor after the Fund's average expenses accrued during the most recent twelve months are subtracted from the unitary fee for that month, and that the Sub-Advisor would pay each of Heitman HK and Heitman GmbH a pro-rata portion of the sub-advisory fee received from the Advisor based on the proportion of assets managed by each. The Board also noted that First Trust would be responsible for the Fund's ordinary operating expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, and license fees, if any, but excluding the fee payment under the Advisory Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions such as dividend and distribution expenses from securities sold short and/or other investment-related costs, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Board reviewed information provided by Management Practice Inc. ("MPI"), an independent source, as well as by First Trust, for the Fund on the advisory fees and expense ratios of other comparable ETFs, as well as data provided by First Trust on advisory fees and expense ratios of global REIT mutual funds. The Board noted that four of the five funds in First Trust's and MPI's peer group overlapped, and that most of the ETFs in the peer groups are not actively managed. The Board noted that the Fund's expense ratio under its proposed unitary fee was above the median expense ratio of its MPI peer group and within the range of the expense ratios of the group of global REIT mutual funds provided by First Trust. The Board compared the Fund's unitary fee to the total expense ratios (after fee waivers and/or expense reimbursements, if any) of other First Trust ETFs, including First Trust ETFs that pay a unitary fee, and to the advisory fees charged by First Trust to other advisory clients, noting the Advisor's statement that it provides services to First Trust FTSE EPRA/NAREIT Developed Markets Real Estate Index Fund ("FFR"), an index ETF that seeks investment results that correspond generally to the price and yield, before fees and expenses, of the FTSE EPRA/NAREIT Developed Index. The Board noted that FFR pays a lower annual unitary fee but considered that it is an index ETF and is not sub-advised. In light of the information considered and the nature, extent and quality of services expected to be provided to the Fund under the Agreements, the Board determined that the proposed unitary fee for the Fund was fair and reasonable. The Board noted that the proposed unitary fee for the Fund was not structured to pass the benefits of any economies of scale on to shareholders as the Fund's assets grow. The Board noted that any reduction in fixed costs associated with the management of the Fund would benefit the Advisor, the Sub-Advisor and the Sub-Sub-Advisors, but that a unitary fee structure provides a level of certainty in expenses for the Fund. The Board noted that First Trust has continued to invest in personnel and infrastructure for the First Trust fund complex. The Board took the costs to be borne by First Trust in connection with its services to be performed for the Fund under the Advisory Agreement into consideration and noted that First Trust was unable to estimate the profitability of the Advisory Agreement to First Trust. The Board considered estimated profitability information provided for the Sub-Advisor and Sub-Sub-Advisors. The Board noted that the Sub-Advisor would be paid by the Advisor from the unitary fee and the Sub-Sub-Advisors would be paid from the sub-advisory fee. The Board considered that the sub-advisory fee rate was negotiated at arm's length between the Advisor and the Sub-Advisor, an unaffiliated third party, and the fee is a net fee payable after the Fund's ordinary operating expenses are paid. The Board considered fall-out benefits described by the Advisor that may be realized from its and FTP's relationship with the Fund. The Board considered fall out benefits described by the Sub-Advisor and Sub-Sub-Advisors that may be realized from their relationship with the Fund, including from soft-dollar arrangements. Based on all the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreements are fair and reasonable and that the approval of the Agreements are in the best interests of the Fund. No single factor was determinative in the Board's analysis. Page 20 FIRST TRUST First Trust Exchange-Traded Fund IV INVESTMENT ADVISOR First Trust Advisors L.P. 120 E.
