FIRST TRUST ------------------- ENERGY INFRASTRUCTURE ------------------- FUND (FIF) SEMI-ANNUAL REPORT For the Six Months Ended May 31, 2015 FIRST TRUST ENERGY INCOME PARTNERS, LLC -------------------------------------------------------------------------------- TABLE OF CONTENTS -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) SEMI-ANNUAL REPORT MAY 31, 2015 Shareholder Letter.......................................................... 1 At a Glance................................................................. 2 Portfolio Commentary........................................................ 3 Portfolio of Investments.................................................... 5 Statement of Assets and Liabilities......................................... 10 Statement of Operations..................................................... 11 Statements of Changes in Net Assets......................................... 12 Statement of Cash Flows..................................................... 13 Financial Highlights........................................................ 14 Notes to Financial Statements............................................... 15 Additional Information...................................................... 22 CAUTION REGARDING FORWARD-LOOKING STATEMENTS This report contains certain forward-looking statements within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. ("First Trust" or the "Advisor") and/or Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") and their respective representatives, taking into account the information currently available to them. 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 First Trust Energy Infrastructure Fund (the "Fund") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and/or the Sub-Advisor and their respective representatives only as of the date hereof. We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof. MANAGED DISTRIBUTION POLICY The Board of Trustees of the Fund has approved a managed distribution policy for the Fund (the "Plan") in reliance on exemptive relief received from the Securities and Exchange Commission that permits the Fund to make periodic distributions of long-term capital gains as frequently as monthly each tax year. Under the Plan, the Fund currently intends to continue to pay a recurring monthly distribution in the amount of $0.11 per share that reflects the distributable cash flow of the Fund. A portion of this monthly distribution may include realized capital gains. This may result in a reduction of the long-term capital gain distribution necessary at year end by distributing realized capital gains throughout the year. The annual distribution rate is independent of the Fund's performance during any particular period. Accordingly, you should not draw any conclusions about the Fund's investment performance from the amount of any distribution or from the terms of the Plan. The Board of Trustees may amend or terminate the Plan at any time without prior notice to shareholders. 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 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. 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 common share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with this semi-annual report which contains detailed information about your investment for the six months ended May 31, 2015, including a portfolio commentary from the Fund's management team, a performance analysis and a market and Fund outlook. Additionally, First Trust has compiled the Fund's financial statements for you to review. We encourage you to read this report and discuss it with your financial advisor. U.S. markets, fueled by accelerating growth and an accommodating Federal Reserve, enjoyed a prosperous year in 2014. However, for the six months covered by this report, some economic and global factors, including the continued conflict in the Middle East and a sharp decline in oil prices, created volatility in the U.S. and global markets. Another factor that has impacted markets is the fact that many economists are predicting the Federal Reserve will begin to raise interest rates this year. As I have written previously, First Trust believes investors should maintain perspective about the markets and have realistic expectations about their investments. Markets will always go up and down, but we believe that having a long-term investment horizon and being invested in quality products can help you reach your goals. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value the relationship and will continue to focus on our disciplined investment approach and long-term perspective to help investors reach their 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.

EIP mainly focuses on investments in energy-related infrastructure assets such as pipelines, power transmission and distribution, petroleum storage and terminals that receive fee-based or regulated income from their corporate and individual customers. EIP manages or supervises approximately $6.1 billion of assets as of May 31, 2015. Private funds advised by EIP include a partnership for U.S. high net worth individuals and a master-and-feeder fund for institutions. EIP also serves as an advisor to separately managed accounts for individuals and institutions and provides its model portfolio to unified managed accounts. Finally, EIP serves as a sub-advisor to three closed-end management investment companies in addition to the First Trust Energy Infrastructure Fund ("FIF" or the "Fund"), an actively managed exchange-traded fund ("ETF"), a sleeve of an actively managed ETF and a sleeve of a series of a variable insurance trust. EIP is a registered investment advisor with the Securities and Exchange Commission. PORTFOLIO MANAGEMENT TEAM JAMES J. MURCHIE EVA PAO PORTFOLIO MANAGER CO-PORTFOLIO MANAGER FOUNDER AND CEO OF PRINCIPAL OF ENERGY INCOME PARTNERS, LLC ENERGY INCOME PARTNERS, LLC COMMENTARY FIRST TRUST ENERGY INFRASTRUCTURE FUND The investment objective of the Fund is to seek a high level of total return with an emphasis on current distributions paid to shareholders. The Fund pursues its objective by investing primarily in securities of companies engaged in the energy infrastructure sector. These companies principally include publicly-traded MLPs, MLP affiliates, YieldCos, pipeline companies, utilities and other infrastructure-related 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"). Under normal market conditions, the Fund invests at least 80% of its managed assets (total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowing) in securities of Energy Infrastructure Companies. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors. MARKET RECAP As measured by the Alerian MLP Total Return Index ("AMZX") and the Philadelphia Stock Exchange Utility Index ("UTY"), the total return for energy-related MLPs and utilities over the six months ended May 31, 2015, was -8.42% and -1.93%, respectively. These figures are according to data collected from several sources, including Alerian Capital Management and Bloomberg. While in the short term, share appreciation of Energy Infrastructure Companies can be volatile, the Sub-Advisor believes that over the longer term, such share appreciation will approximate growth in monthly cash distributions and dividends per share. Over the last 10 years, growth in MLP distributions and utility dividends has averaged 5.4% and 4.3%, respectively. Over the last 12 months, the cash distributions of MLPs decreased by about 4.6% and utilities increased by about 3.6% (source: Alerian Capital Management and Bloomberg). PERFORMANCE ANALYSIS On a net asset value ("NAV") basis, the Fund provided a total return(2) of -1.56%, including the reinvestment of distributions for the six months ended May 31, 2015. This compares, according to collected data, to a -4.91% return for a blended index consisting of the UTY (50%) and the AMZX (50%), (the "Blended Index"). Unlike the Fund, the Blended Index does not incur (1) Yieldcos are publicly traded entities that own, operate and acquire contracted renewable and conventional generation and thermal and other infrastructure assets, which are generally not MLP-qualifying assets. Like MLPs, Yieldcos generally seek to position themselves as vehicles for investors seeking stable and growing dividend income from a diversified portfolio of lower-risk, hiqh-quality assets. (2) Total return is based on the combination of reinvested dividends, capital gains and return of capital distributions, if any, at prices obtained by the Dividend Reinvestment Plan and changes in NAV per share for NAV returns and changes in common share price for market value returns. Total returns do not reflect sales load and are not annualized for periods less than one year. Past performance is not indicative of future results. Page 3 -------------------------------------------------------------------------------- PORTFOLIO COMMENTARY (CONTINUED) -------------------------------------------------------------------------------- fees and expenses. On a market value basis, the Fund had a total return, including the reinvestment of distributions, of -1.60% for the period. As of May 31, 2015, the Fund's market price per share was $21.99, while the NAV per share was $24.84, a discount of 11.47%. As of November 30, 2014, the Fund's market price per share was $23.00, while the NAV per share was $25.97, a discount of 11.44%. The Fund declared regular monthly Common Share distributions of $0.11 per share for each month from December 2014 through May 2015. During the six-month period, the Fund's NAV outperformed the -4.91% return of the Blended Index. The MLP portion of the portfolio outperformed the AMZX due in part to the Fund's overweight positions in MLPs that benefited from corporate restructurings and underweight positions in MLPs with commodity exposure. The non-MLP portion of the portfolio outperformed the UTY index. Outperforming non-MLP positions in the Fund included MLP parent corporations and Canadian infrastructure corporations. This positive performance was offset by the Fund's underweight positions in UTY members that outperformed the index. Income was enhanced by writing covered calls on select portfolio positions. An important factor that affected the return of the Fund was its use of financial leverage through the use of a line of credit. The Fund has a committed facility agreement with The Bank of Nova Scotia, with a maximum commitment amount of $200,000,000. The Fund uses leverage because the Sub-Advisor believes that, over time, leverage can enhance total return for common shareholders. However, the use of leverage can also increase the volatility of the Fund's NAV and therefore volatility of the Fund's share price. For example, if the prices of securities held by the Fund decline, the effect of changes in common share NAV and common shareholder total return loss is magnified by the use of leverage. Conversely, leverage may enhance common share returns during periods when the prices of securities held by the Fund generally are rising. Unlike the Fund, AMZX and UTY are not leveraged. Leverage had a negative impact on the performance of the Fund over this reporting period. MARKET AND FUND OUTLOOK MLPs continue to play an integral role in the restructuring of more diversified energy conglomerates. This restructuring includes the creation by these more diversified conglomerates of subsidiaries with high dividend payout ratios that contain assets with stable cash flows such as pipelines, storage terminals and electric power assets with long-term fixed-price contracts. The restructuring can also include the divestiture by some of the parent companies of most or all of their cyclical businesses, leaving the parent company looking very similar to an old-fashioned pipeline utility with a large holding in a subsidiary MLP. In our view, these diversified energy conglomerates are restructuring so that their regulated infrastructure assets that have predictable cash flows may be better valued by the market. In our opinion, the result is a better financing tool to raise capital for the new energy infrastructure projects related to the rapid growth of North American oil and gas production. This phenomenon is beginning to spread to the power utility industry, but instead of spinning out MLPs, diversified power companies are spinning out regular "C" corporations with higher dividend payout ratios (relative to earnings). Calendar year-to-date through May 31, 2015, five MLPs have conducted initial public offerings ("IPOs"). In addition, there was secondary financing activity for MLPs during the reporting period, as MLPs continued to fund their ongoing investments in new pipelines, processing and storage facilities. During the same period, there have been 22 secondary equity offerings for MLPs, which raised an aggregate of $6.4 billion in proceeds during the period. This compares to $19.1 billion raised in all of 2014. Calendar year-to-date through May 31, 2015, MLPs also found access to the public debt markets, raising an aggregate of $21 billion in 21 offerings. This compares to $28.1 billion in calendar year 2014. (Source: Barclays Capital). Capital expenditures for the 20 companies that comprise the UTY Index were $22 billion for the first calendar quarter of 2015. The capital expenditure estimate for 2015 is $93 billion. (Source: Bloomberg) This compares to $81 billion in 2013 and about $86.3 billion in 2014. The expenditures are in response to needs such as reliability, interconnection, modernization and growing demand. These capital investments are supported, in part, by federal and state regulation, which allows companies to recoup investments they have made in the rates they charge their customers. The Fund continues to aim to weight the portfolio toward Energy Infrastructure Companies with mostly non-cyclical cash flows, investment-grade ratings, conservative balance sheets, modest and/or flexible organic growth commitments and available liquidity under revolving lines of credit. Since the Fund invests in securities that tend to have high dividend payout ratios (relative to earnings), in EIP's opinion, securities with unpredictable cyclical cash flows make a poor fit within the portfolio. While there are some businesses within the Fund's portfolio whose cash flows are cyclical, they are generally small and analyzed in the context of each company's financial and operating leverage and payout ratio.

Page 14 See Notes to Financial Statements -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) 1. ORGANIZATION First Trust Energy Infrastructure Fund (the "Fund") is a non-diversified, closed-end management investment company organized as a Massachusetts business trust on February 22, 2011 and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund trades under the ticker symbol FIF on the New York Stock Exchange ("NYSE"). The Fund's investment objective is to seek a high level of total return with an emphasis on current distributions paid to shareholders. The Fund seeks to achieve its objective by investing primarily in securities of companies engaged in the energy infrastructure sector. Energy infrastructure 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"). For purposes of the Fund's investment objective, total return includes capital appreciation of, and all distributions received from, securities in which the Fund will invest, taking into account the varying tax characteristics of such securities. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors. 2. MANAGED DISTRIBUTION POLICY The Board of Trustees of the Fund has approved a managed distribution policy for the Fund (the "Plan") in reliance on exemptive relief received from the Securities and Exchange Commission that permits the Fund to make periodic distributions of long-term capital gains as frequently as monthly each tax year. Under the Plan, the Fund currently intends to continue to pay a recurring monthly distribution in the amount of $0.11 per share that reflects the distributable cash flow of the Fund. A portion of this monthly distribution may include realized capital gains. This may result in a reduction of the long-term capital gain distribution necessary at year end by distributing realized capital gains throughout the year. The annual distribution rate is independent of the Fund's performance during any particular period. Accordingly, you should not draw any conclusions about the Fund's investment performance from the amount of any distribution or from the terms of the Plan. The Board of Trustees may amend or terminate the Plan at any time without prior notice to shareholders. 3. 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 its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. PORTFOLIO VALUATION The net asset value ("NAV") of the Common Shares of the Fund is determined daily as of the close of regular trading on the NYSE, normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund's NAV per Common Share is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses, dividends declared but unpaid and any borrowings of the Fund) by the total number of Common Shares outstanding. The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the 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 Fund's Board of Trustees, and in accordance with provisions of the 1940 Act. Investments valued by the Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund's investments are valued as follows: Common stocks, MLPs and other equity securities listed on any national or foreign exchange (excluding The NASDAQ(R) 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. Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Over-the-counter options contracts are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Page 15 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (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. Swaps are fair valued utilizing quotations provided by a third-party pricing service or, if the pricing service does not provide a value, by quotes provided by the selling dealer or financial institution. Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Fund's Board of Trustees or its delegate, the Advisor's Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) 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. 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 May 31, 2015, is included with the Fund's Portfolio of Investments. Page 16 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) B. OPTION CONTRACTS The Fund is subject to equity price risk in the normal course of pursuing its investment objective and may write (sell) options to hedge against changes in the value of equities. Also, the Fund seeks to generate additional income, in the form of premiums received, from writing (selling) the options. The Fund may write (sell) covered call or put options ("options") on all or a portion of the common stock and MLPs held in the Fund's portfolio as determined to be appropriate by the Sub-Advisor. The number of options the Fund can write (sell) is limited by the amount of common stock and MLPs the Fund holds in its portfolio. The Fund will not write (sell) "naked" or uncovered options. When the Fund writes (sells) an option, an amount equal to the premium received by the Fund is included in "Options written, at value" on the Fund's Statement of Assets and Liabilities. Options are marked-to-market daily and their value will be affected by changes in the value and dividend rates of the underlying equity securities, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying equity securities and the remaining time to the options' expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or trading volume diminishes. Options the Fund writes (sells) will either be exercised, expire or be cancelled pursuant to a closing transaction. If the price of the underlying equity security exceeds the option's exercise price, it is likely that the option holder will exercise the option. If an option written (sold) by the Fund is exercised, the Fund would be obligated to deliver the underlying security to the option holder upon payment of the strike price. In this case, the option premium received by the Fund will be added to the amount realized on the sale of the underlying security for purposes of determining gain or loss. If the price of the underlying equity security is less than the option's strike price, the option will likely expire without being exercised. The option premium received by the Fund will, in this case, be treated as short-term capital gain on the expiration date of the option. The Fund may also elect to close out its position in an option prior to its expiration by purchasing an option of the same series as the option written (sold) by the Fund. Gain or loss on options is presented separately as "Net realized gain (loss) on written options" on the Statement of Operations. The options that the Fund writes (sells) give the option holder the right, but not the obligation, to purchase a security from the Fund at the strike price on or prior to the option's expiration date. The ability to successfully implement the writing (selling) of covered call options depends on the ability of the Sub-Advisor to predict pertinent market movements, which cannot be assured. Thus, the use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market value, which may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security that it might otherwise sell. As the writer (seller) of a covered option, the Fund foregoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the option above the sum of the premium and the strike price of the option, but has retained the risk of loss should the price of the underlying security decline. The writer (seller) of an option has no control over the time when it may be required to fulfill its obligation as a writer (seller) of the option. Once an option writer (seller) 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 to the option holder at the exercise price. Over-the-counter options have the risk of the potential inability of counterparties to meet the terms of their contracts. The Fund's maximum equity price risk for purchased options is limited to the premium initially paid. In addition, certain risks may arise upon entering into option contracts including the risk that an illiquid secondary market will limit the Fund's ability to close out an option contract prior to the expiration date and that a change in the value of the option contract may not correlate exactly with changes in the value of the securities hedged. C. SWAP AGREEMENTS The Fund may enter into total return equity swap and interest rate swap agreements. A swap is a financial instrument that typically involves the exchange of cash flows between two parties ("Counterparties") on specified dates (settlement dates) where the cash flows are based on agreed upon prices, rates, etc. Swap agreements are individually negotiated and involve the risk of the potential inability of the Counterparties to meet the terms of the agreement. In connection with these agreements, cash and securities may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default under the swap agreement or bankruptcy/insolvency of a party to the swap agreement. In the event of a default by a Counterparty, the Fund will seek withdrawal of the collateral and may incur certain costs exercising its rights with respect to the collateral. 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. Swap agreements may increase or decrease the overall volatility of the investments of the Fund. The performance of swap agreements may be affected by changes in the specific interest rate, security, currency, or other factors that determine the amounts of payments due to and from the Fund. The Fund's maximum equity price risk to meet its future payments under swap agreements outstanding at May 31, 2015 is equal to the total notional amount as shown on the Portfolio of Investments. The notional amount represents the U.S. dollar value of the contract as of the day of the opening transaction or contract reset. When the Fund enters into a swap agreement, any premium paid is included in "Swap contracts, at value" on the Statement of Assets and Liabilities. The Fund held interest rate swap agreements at May 31, 2015. An interest rate swap agreement involves the Fund's agreement to exchange a stream of interest payments for another party's stream of cash flows. Interest rate swaps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Fund is contractually obligated to make. Page 17 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) D. 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. The Fund will rely to some extent on information provided by the MLPs, which is not necessarily timely, to estimate taxable income allocable to the MLP units held in the Fund's portfolio. 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. For the six months ended May 31, 2015, distributions of $4,178,778 received from MLPs have been reclassified as return of capital. The cost basis of applicable MLPs has been reduced accordingly. E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS The Fund will distribute to holders of its Common Shares monthly dividends of all or a portion of its net income after the payment of interest in connection with leverage, if any. Distributions of any long-term capital gains earned by the Fund are distributed at least annually. Distributions will automatically be reinvested into additional Common Shares pursuant to the Fund's Dividend Reinvestment Plan unless cash distributions are elected by the shareholder. Distributions from 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 have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some point in the future. The tax character of distributions paid during the fiscal year ended November 30, 2014 is as follows: Distributions paid from: Ordinary income................................... $ 7,795,582 Capital gain...................................... 38,829,529 Return of capital................................. 1,638,038 As of November 30, 2014, the components of distributable earnings and net assets on a tax basis were as follows: Undistributed ordinary income..................... $ -- Undistributed capital gains....................... -- ------------- Total undistributed earnings...................... -- Accumulated capital and other losses.............. -- Net unrealized appreciation (depreciation)........ 123,389,404 ------------- Total accumulated earnings (losses)............... 123,389,404 Other............................................. (16,747) Paid-in capital................................... 332,476,073 ------------- Net assets........................................ $ 455,848,730 ============= F. 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 or 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 November 30, 2014, the Fund had no 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 November 30, 2014, the Fund had no qualified late year losses. Page 18 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable years ending 2011, 2012, 2013 and 2014 remain open to federal and state audit. As of May 31, 2015, 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. G. EXPENSES The Fund will pay all expenses directly related to its operations. H. 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. 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 is included in "Net realized gain (loss) on investments" on the Statement of Operations. I. OFFSETTING ON THE STATEMENT OF ASSETS AND LIABILITIES In December 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-11 "Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"). This disclosure requirement is intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a fund's financial position. ASU 2011-11 requires entities to disclose both gross and net information about both instruments and transactions eligible for offset on the Statement of Assets and Liabilities, and disclose instruments and transactions subject to master netting or similar agreements. In addition, in January 2013, FASB issued Accounting Standards Update No. 2013-1 "Clarifying the Scope of Offsetting Assets and Liabilities" ("ASU 2013-1"), specifying exactly which transactions are subject to offsetting disclosures. The scope of the disclosure requirements is limited to derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. ASU 2011-11 and ASU 2013-1 are effective for financial statements with fiscal years beginning on or after January 1, 2013, and interim periods within those fiscal years. For financial reporting purposes, the Fund does not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statement of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and involvency) for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. At May 31, 2015, derivative assets and liabilities (by type) on a gross basis are as follows: GROSS AMOUNTS NOT OFFSET IN THE STATEMENT OF NET AMOUNTS OF ASSETS AND LIABILITIES GROSS GROSS AMOUNTS LIABILITIES PRESENTED -------------------------- AMOUNTS OF OFFSET IN THE IN THE STATEMENT CASH RECOGNIZED STATEMENT OF ASSETS OF ASSETS AND FINANCIAL SEGREGATED AS NET LIABILITIES AND LIABILITIES LIABILITIES INSTRUMENTS COLLATERAL AMOUNT ---------------------------------------------------------------------------------------------------------------------------- Interest Rate Swap Contracts $ (2,580,330) $ -- $ (2,580,330) $ -- $ 2,580,330 $ -- 4. 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 Fund's investment portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. For these investment management services, First Trust is entitled to a monthly fee calculated at an annual rate of 1.00% of the Fund's Managed Assets (the average daily total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowings). First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250. Page 19 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) EIP serves as the Fund's sub-advisor and manages the Fund's portfolio subject to First Trust's supervision. The Sub-Advisor receives a monthly sub-advisory fee calculated at an annual rate of 0.50% of the Fund's Managed Assets that is paid by First Trust out of its investment advisory fee. 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 the EIP. In addition, on March 27, 2014, FTCP, through a wholly-owned subsidiary, purchased a preferred interest in EIP. The preferred interest was non-voting and did not share in the profits or losses of EIP. EIP redeemed all of the preferred shares in March 2015. BNY Mellon Investment Servicing (US) Inc. ("BNYM IS") serves as the Fund's administrator, fund accountant and transfer agent in accordance with certain fee arrangements. As administrator and fund accountant, BNYM IS is responsible for providing certain administrative and accounting services to the Fund, including maintaining the Fund's books of account, records of the Fund's securities transactions, and certain other books and records. As transfer agent, BNYM IS is responsible for maintaining shareholder records for the Fund. The Bank of New York Mellon ("BNYM") serves as the Fund's custodian in accordance with certain fee arrangements. As custodian, BNYM is responsible for custody of the Fund's assets. 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 pro rata among each fund in the First Trust Fund Complex based on 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 Fund for acting in such capacities. 5. PURCHASES AND SALES OF SECURITIES Cost of purchases and proceeds from sales of investments, excluding short-term investments, for the six months ended May 31, 2015, were $92,919,805 and $112,803,243, respectively. 6.

STATEMENT OF OPERATIONS LOCATION ------------------------------------------------------------------------------- EQUITY RISK EXPOSURE Net realized gain (loss) on written options $ 1,068,543 Net change in unrealized appreciation (depreciation) on written options 1,900,628 INTEREST RATE RISK EXPOSURE Net realized gain (loss) on swap contracts (770,351) Net change in unrealized appreciation (depreciation) on swap contracts (878,937) The average volume of interest rate swaps was $72,950,000 for the six months ended May 31, 2015. The Fund does not have the right to offset financial assets and financial liabilities related to option contracts on the Statement of Assets and Liabilities. 7. BORROWINGS During the period covered by this report, the Fund maintained a committed facility agreement with The Bank of Nova Scotia ("Scotia") with a maximum commitment amount of $200,000,000 and a borrowing rate equal to the 1-month LIBOR plus 70 basis points. In addition, under the facility, the Fund pays a commitment fee of 0.20% on the undrawn amount of such facility. The average amount outstanding under the facility for the six months ended May 31, 2015 was $145,736,264, with a weighted average interest rate of 0.87%. As of May 31, 2015, the Fund had outstanding borrowings of $141,000,000 under this committed facility agreement. The high and low annual interest rates for the six months ended May 31, 2015, were 0.89% and 0.81%, respectively. The interest rate at May 31, 2015 was 0.88%. Prior to December 22, 2014, the maximum commitment amount was $165,000,000 and the borrowing rate was 1-month LIBOR plus 65 basis points. 8. INDEMNIFICATION 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. 9. INDUSTRY CONCENTRATION RISK The Fund invests at least 80% of its Managed Assets in securities issued by Energy Infrastructure Companies. Given this industry concentration, the Fund is more susceptible to adverse economic or regulatory occurrences affecting that industry than an investment company that is not concentrated in a single industry. Energy Infrastructure Company issuers may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. 10. SUBSEQUENT EVENT Management has evaluated the impact of all subsequent events to the Fund through the date the financial statements were issued and has determined that there was the following subsequent event: On June 22, 2015, the Fund declared a distribution of $0.11 per share to Common Shareholders of record on July 6, 2015, payable July 15, 2015. On July 20, 2015, the Fund declared a distribution of $0.11 per share to Common Shareholders of record on August 5, 2015, payable August 17, 2015. Page 21 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) DIVIDEND REINVESTMENT PLAN If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund's Dividend Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund, to receive cash distributions, all dividends, including any capital gain distributions, on your Common Shares will be automatically reinvested by BNY Mellon Investment Servicing (US) Inc. (the "Plan Agent"), in additional Common Shares under the Plan. If you elect to receive cash distributions, you will receive all distributions in cash paid by check mailed directly to you by the Plan Agent, as the dividend paying agent. If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows: (1) If Common Shares are trading at or above net asset value ("NAV") at the time of valuation, the Fund will issue new shares at a price equal to the greater of (i) NAV per Common Share on that date or (ii) 95% of the market price on that date. (2) If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants' accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date except where temporary curtailment or suspension of purchases is necessary to comply with federal securities laws. Interest will not be paid on any uninvested cash payments. You may elect to opt-out of or withdraw from the Plan at any time by giving written notice to the Plan Agent, or by telephone at (866) 340-1104, in accordance with such reasonable requirements as the Plan Agent and the Fund may agree upon. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan, and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions. The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. The Plan Agent will forward to each participant any proxy solicitation material and will vote any shares so held only in accordance with proxies returned to the Fund. Any proxy you receive will include all Common Shares you have received under the Plan. There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Capital gains and income are realized although cash is not received by you. Consult your financial advisor for more information. If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing BNY Mellon Investment Servicing (US) Inc., 301 Bellevue Parkway, Wilmington, Delaware 19809. -------------------------------------------------------------------------------- PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that the Fund uses to determine how to vote proxies and information on how the Fund voted proxies relating to portfolio investments 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 located at http://www.sec.gov.

The following summarizes some, but not all, of the risks that should be considered for the Fund. For additional information about the risks associated with investing in the Fund, please see the Fund's prospectus and statement of additional information, as well as other Fund regulatory filings. INDUSTRY CONCENTRATION RISK: The Fund invests at least 80% of its Managed Assets in securities issued by Energy Infrastructure Companies. Given this industry concentration, the Fund is more susceptible to adverse economic or regulatory occurrences affecting that industry than an investment company that is not concentrated in a single industry. Energy Infrastructure Company issuers may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. CURRENCY RISK: The value of securities denominated or quoted in foreign currencies may be adversely affected by fluctuations in the relative currency exchange rates and by exchange control regulations. The Fund's investment performance may be negatively affected by a devaluation of a currency in which the Fund's investments are denominated or quoted. Further, the Fund's investment performance may be significantly affected, either positively or negatively, by currency exchange rates because the U.S. dollar value of securities denominated or quoted in another currency will increase or decrease in response to changes in the value of such currency in relation to the U.S. dollar. While certain of the Fund's non-U.S. dollar-denominated securities may be hedged into U.S. dollars, hedging may not alleviate all currency risks. INVESTMENT AND MARKET RISK: An investment in the Fund's Common Shares is subject to investment risk, including the possible loss of the entire principal invested. An investment in Common Shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. Common Shares at any point in time may be worth less than the original investment, even after taking into account the reinvestment of Fund dividends and distributions. Security prices can fluctuate for several reasons including the general condition of the securities markets, or when political or economic events affecting the issuers occur. When the Advisor or Sub-Advisor determines that it is temporarily unable to follow the Fund's investment strategy or that it is impractical to do so (such as when a market disruption event has occurred and trading in the securities is extremely limited or absent), the Fund may take temporary defensive positions. LEVERAGE RISK: The use of leverage results in additional risks and can magnify the effect of any losses. The funds borrowed pursuant to a leverage borrowing program constitute a substantial lien and burden by reason of their prior claim against the income of the Fund and against the net assets of the Fund in liquidation. If the Fund is not in compliance with certain credit facility provisions, the Fund may not be permitted to declare dividends or other distributions. Page 23 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF) MAY 31, 2015 (UNAUDITED) 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. NON-U.S. RISK: The Fund may invest a portion of its assets in the equity securities of issuers domiciled in jurisdictions other than the U.S. Investments in the securities and instruments of non-U.S. issuers involve certain considerations and risks not ordinarily associated with investments in securities and instruments of U.S. issuers. Non-U.S. companies are not generally subject to uniform accounting, auditing and financial standards and requirements comparable to those applicable to U.S. companies. Non-U.S. securities exchanges, brokers and listed companies may be subject to less government supervision and regulation than exists in the United States. Dividend and interest income may be subject to withholding and other non-U.S. taxes, which may adversely affect the net return on such investments. A related risk is that there may be difficulty in obtaining or enforcing a court judgment abroad. QUALIFIED DIVIDEND INCOME TAX RISK: There can be no assurance as to what portion of the distributions paid to the Fund's Common Shareholders will consist of tax-advantaged qualified dividend income. Certain distributions designated by the Fund as derived from qualified dividend income will be taxed in the hands of non-corporate Common Shareholders at the rates applicable to long-term capital gains, provided certain holding period and other requirements are satisfied by both the Fund and the Common Shareholders. Additional requirements apply in determining whether distributions by foreign issuers should be regarded as qualified dividend income. Certain investment strategies of the Fund will limit the Fund's ability to meet these requirements and consequently will limit the amount of qualified dividend income received and distributed by the Fund. A change in the favorable provisions of the federal tax laws with respect to qualified dividends may result in a widespread reduction in announced dividends and may adversely impact the valuation of the shares of dividend-paying companies. RESTRICTED SECURITIES RISK: The Fund may invest in unregistered or otherwise restricted securities. The term "restricted securities" refers to securities that are unregistered or are held by control persons of the issuer and securities that are subject to contractual restrictions on their resale. As a result, restricted securities may be more difficult to value and the Fund may have difficulty disposing of such assets either in a timely manner or for a reasonable price. In order to dispose of an unregistered security, the Fund, where it has contractual rights to do so, may have to cause such security to be registered. A considerable period may elapse between the time the decision is made to sell the security and the time the security is registered so that the Fund could sell it. Contractual restrictions on the resale of securities vary in length and scope and are generally the result of a negotiation between the issuer and acquirer of the securities. The Fund would, in either case, bear market risks during that period. Page 24 FIRST TRUST INVESTMENT ADVISOR First Trust Advisors L.P. 120 E.

The Fund is likewise obligated to file with the SEC the information contained in any such notice to shareholders.
