                  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 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 which 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 its 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.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment. It
includes details about the Fund and presents data and analysis that provide
insight into the Fund's performance and investment approach.

By reading the portfolio commentary by the portfolio management team of the
Fund, you may obtain an understanding of how the market environment affected the
Fund's performance. 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 EIP
are just that: informed opinions. They should not be considered to be promises
or advice. The opinions, like the statistics, cover the period through the date
on the cover of this report. The risks of investing in the Fund are spelled out
in the prospectus, the statement of additional information, this report and
other Fund regulatory filings.

                                   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 master limited partnerships ("MLPs"), MLP affiliates, Canadian income
equities, 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's
investment objective will be achieved. 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") (together, the "Blended Index"), the total
return for energy-related MLPs and utilities over the fiscal year ended November
30, 2014, was 12.87% and 24.72%, 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 per share quarterly cash
distributions and dividends. Over the last 10 years, growth in per share MLP
distributions and utility dividends has averaged 7.3% and 5.0%, respectively.
Over the last 12 months, the cash distributions of MLPs increased by about 3.5%
and utilities increased by about 0.8% (source: Alerian Capital Management and
Bloomberg).

PERFORMANCE ANALYSIS

On a net asset value ("NAV") basis, the Fund provided a total return(1) of
31.02%, including the reinvestment of dividends for the year ended November 30,
2014. This compares, according to collected data, to a 19.01% return of the
Blended Index. Unlike the Fund, the Blended Index does not incur fees and
expenses. On a market value basis, the Fund had a total return,

(1)   Total return is based on the combination of reinvested dividend, capital
      gain 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.

PORTFOLIO COMMENTARY (CONTINUED)

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                                 ANNUAL REPORT
                               NOVEMBER 30, 2014


including the reinvestment of dividends, of 19.18% for the period. At period
end, the Fund was priced at $23.00, while the NAV was $25.97, a discount of
11.44%. On November 30, 2013, the Fund was priced at $21.71, while the NAV was
$22.30, a discount of 2.65%.

The Fund declared regular monthly Common Share distributions of $0.11 per share
for each month from December 2013 through November 2014. In addition, the Fund
declared a special long-term capital gain distribution of $1.43 per share in
November 2014.

The Fund's NAV outperformed the 19.01% return of the Blended Index. The MLP
portion of the portfolio outperformed the AMZX due in part to MLPs with
announced acquisitions of assets from their general partner or sponsor and
merger activity. The non-MLP portion of the portfolio outperformed the UTY
index. Outperforming non-MLP positions 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 $165,000,000. 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 NAV and
therefore volatility of the 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 positive 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 an MLP,
diversified power companies are spinning out a regular "C" corporation with a
higher dividend payout ratio (relative to earnings). By EIP's count, nine such
"Yield-Co.'s" have been created in the last year, and EIP expects more will be
created.

Calendar year-to-date through November 30, 2014, the MLP asset class has
experienced 19 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 59 secondary equity
offerings for MLPs, which raised $18.8 billion in proceeds. This compares to
$20.3 billion raised in all of 2013. Calendar year-to-date through November 30,
2014, MLPs also found access to the public debt markets, raising $26.9 billion
in 28 offerings. This compares to $19.9 billion in calendar year 2013 (source:
Barclays Capital).

Capital expenditures for the 20 companies that comprise the UTY Index were $61.7
billion for the first three calendar quarters of 2014. Annualizing this number
would result in an estimate of about $82.2 billion for the year. This compares
to $80 billion in 2012 and about $81 billion in 2013. 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 liquidity on their revolving lines of credit. Since the Fund invests in
securities that tend to have high dividend payout ratios (as measured versus
earnings), in EIP's opinion, securities with unpredictable cyclical cash flows
make them 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.

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                               NOVEMBER 30, 2014


                                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 which 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 its 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 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 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 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.

      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.


                                                                         Page 15

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                               NOVEMBER 30, 2014

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 methodology 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 November 30, 2014, is
included with the Fund's Portfolio of Investments.

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

--------------------------------------------------------------------------------

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                               NOVEMBER 30, 2014

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 the Counterparty, the Fund will seek withdrawal of this
collateral and may incur certain costs exercising its right 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 a
change 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 November 30, 2014 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 November 30, 2014. 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.

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.


                                                                         Page 17

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                               NOVEMBER 30, 2014

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 year ended November 30, 2014, distributions of $7,911,163
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. Permanent differences
incurred during the year ended November 30, 2014, primarily as a result of
differing book and tax treatments on the sale of MLP investments, have been
reclassified at year end to reflect an increase in accumulated net investment
income (loss) of $8,755,203 a decrease in accumulated net realized gain (loss)
on investments of $9,039,770 and an increase to paid-in capital of $284,567. Net
assets were not affected by these reclassifications.

The tax character of distributions paid during the fiscal years ended November
30, 2014 and 2013 is as follows:

Distributions paid from:                                 2014           2013
Ordinary income ..................................   $  7,795,582   $ 36,268,003
Capital gain......................................   $ 38,829,529   $ 35,321,879
Return of capital.................................   $  1,638,038   $    918,918

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.......................             --

                                                     ============


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.

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 November 30, 2014,
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.

                               NOVEMBER 30, 2014


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.

The Fund adopted the disclosure requirement on netting for the current reporting
period. For financial reporting purposes, the Fund does not offset financial
assets and financial liabilities that are subject to master netting arrangements
or similar agreements on the Statement of Assets and Liabilities. The Fund's
right to setoff may be restricted or prohibited by the bankruptcy or insolvency
laws of the particular jurisdiction to which a specific master netting or
similar agreement counterparty is subject.

At November 30, 2014, derivative assets and liabilities (by type) on a gross
basis are as follows:





                                                                                                GROSS AMOUNTS

The following table presents the amount of net realized gain (loss) and change
in net unrealized appreciation (depreciation) recognized for the year ended

The average volume of interest rate swaps was $47,698,077 for the year ended
November 30, 2014.

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 $165,000,000 and a borrowing rate equal to the 1-month
LIBOR plus 65 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 for the year ended November 30, 2014 was $149,425,479, with a
weighted average interest rate of 0.76%. As of November 30, 2014, the Fund had
outstanding borrowings of $158,000,000 under this committed facility agreement.
The high and low annual interest rates for the year ended November 30, 2014,
were 0.81% and 0.75%, respectively. The interest rate at November 30, 2014 was
0.80%.

                               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 EVENTS

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
were the following subsequent events:

On December 22, 2014, the Fund declared a distribution of $0.11 per share to
Common Shareholders of record on January 6, 2015, payable January 15, 2015.

On January 20, 2015, the Fund declared a distribution of $0.11 per share to
Common Shareholders of record on February 4, 2015, payable February 17, 2015.

Effective December 22, 2014, the committed facility agreement with Scotia was
amended, whereby the maximum commitment amount was increased from $165,000,000
to $200,000,000 and the borrowing rate was increased from 1-month LIBOR plus 65
basis points to 1-month LIBOR plus 70 basis points.

On December 8, 2014, the Board of Trustees of the Fund approved a managed
distribution policy for the Fund (the "Plan") in reliance on exemptive relieve
received from the Securities and Exchange Commission which permits the Fund to
make periodic distributions of long-term capital gains as frequently as monthly
each tax year. See Note 2 in the Notes to Financial Statements for additional
discussion of the Plan.


                                                                         Page 21





--------------------------------------------------------------------------------
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF FIRST TRUST ENERGY INFRASTRUCTURE
FUND:

We have audited the accompanying statement of assets and liabilities of First
Trust Energy Infrastructure Fund (the "Fund"), including the portfolio of
investments, as of November 30, 2014, and the related statements of operations
and cash flows for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Fund is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2014 by correspondence with the Fund's
custodian and brokers; where replies were not received, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
First Trust Energy Infrastructure Fund as of November 30, 2014, and the results
of its operations and its cash flows for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented, in conformity with accounting
principles generally accepted in the United States of America.

ADDITIONAL INFORMATION
--------------------------------------------------------------------------------

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                         NOVEMBER 30, 2014 (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

                              RISK CONSIDERATIONS

Risks are inherent in all investing. 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.

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                         NOVEMBER 30, 2014 (UNAUDITED)


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.

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.

                        INVESTMENT MANAGEMENT AGREEMENT

BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF INVESTMENT MANAGEMENT
AND SUB-ADVISORY AGREEMENTS

The Board of Trustees of First Trust Energy Infrastructure Fund (the "Fund"),
including the Independent Trustees, unanimously approved the continuation of the
Investment Management Agreement (the "Advisory Agreement") between the Fund and
First Trust Advisors L.P. (the "Advisor") and the Investment Sub-Advisory
Agreement (the "Sub-Advisory Agreement" and together with the Advisory
Agreement, the "Agreements") among the Fund, the Advisor and Energy Income
Partners, LLC (the "Sub-Advisor"), at a meeting held on June 8-9, 2014. The
Board of Trustees determined that the continuation of the Agreements is in the
best interests of the Fund in light of the extent and quality of the services
provided and such other matters as the Board considered to be relevant in the
exercise of its reasonable business judgment.


                                                                         Page 25

                  FIRST TRUST ENERGY INFRASTRUCTURE FUND (FIF)
                         NOVEMBER 30, 2014 (UNAUDITED)


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 from counsel to the Independent Trustees. The reports, among other
things, outlined the services provided by the Advisor and the Sub-Advisor
(including the relevant personnel responsible for these services and their
experience); the advisory and sub-advisory fees for the Fund as compared to fees
charged to other clients of the Advisor and the Sub-Advisor and as compared to
fees charged by investment advisors and sub-advisors to comparable funds;
expenses of the Fund as compared to expense ratios of comparable funds; the
nature of expenses 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; any fall out benefits to the Advisor and the Sub-Advisor; and
information on the Advisor's and the Sub-Advisor's compliance programs.
Following receipt of this information, counsel to the Independent Trustees posed
follow-up questions to the Advisor, and the Independent Trustees and their
counsel met separately to discuss the information provided by the Advisor and
the Sub-Advisor, including the supplemental responses. The Board applied its
business judgment to determine whether the arrangements between the Fund and the
Advisor and among the Fund, the Advisor and the Sub-Advisor are reasonable
business arrangements from the Fund's perspective as well as from the
perspective of shareholders. The Board considered that shareholders chose to
invest or remain invested in the Fund knowing that the Advisor and the
Sub-Advisor manage the Fund.

In reviewing the Agreements, the Board considered the nature, extent and quality
of services provided by the Advisor and the Sub-Advisor under the Agreements.
The Board considered the Advisor's statements regarding the incremental benefits
associated with the Fund's advisor/sub-advisor management structure. With
respect to the Advisory Agreement, the Board considered that the Advisor is
responsible for the overall management and administration of the Fund and
reviewed the services provided by the Advisor to the Fund, including the
oversight of the Sub-Advisor. The Board noted the compliance program that had
been developed by the Advisor and considered that it includes a robust program
for monitoring the Sub-Advisor's compliance with the 1940 Act and the Fund's
investment objective and policies. With respect to the Sub-Advisory Agreement,
the Board noted the background and experience of the Sub-Advisor's portfolio
management team. At the meeting, the Board received a presentation from
representatives of the Sub-Advisor, including the portfolio managers, discussing
the services that the Sub-Advisor provides to the Fund and how the Sub-Advisor
manages the Fund's investments. In light of the information presented and the
considerations made, the Board concluded that the nature, extent and quality of
services provided to the Fund by the Advisor and the Sub-Advisor under the
Agreements have been and are expected to remain satisfactory and that the
Sub-Advisor, under the oversight of the Advisor, has managed the Fund consistent
with its investment objective and policies.

The Board considered the advisory and sub-advisory fees paid under the
Agreements. The Board considered the advisory fees charged by the Advisor to
similar funds and other non-fund clients, noting that the Advisor provides
advisory services to three other closed-end funds and one actively managed
exchange-traded fund ("ETF") sub-advised by the Sub-Advisor and certain
separately managed accounts that may have investment objectives and policies
similar to the Fund's. The Board noted that the Advisor charges the same
advisory fee rate to the Fund and the other closed-end funds sub-advised by the
Sub-Advisor and a lower advisory fee rate to the actively managed ETF and the
separately managed accounts. The Board noted the Advisor's statement that the
nature of the services provided to the separately managed accounts is not
comparable to those provided to the Fund. The Board considered the sub-advisory
fee and how it relates to the Fund's overall advisory fee structure and noted
that the sub-advisory fee is paid by the Advisor from its advisory fee. The
Board noted that the Sub-Advisor provides sub-advisory services to the other
closed-end funds and the actively managed ETF noted above and that the
sub-advisory fee rate for the other closed-end funds is the same as that
received from the Advisor for the Fund. The Board also considered information
provided by the Sub-Advisor as to the fees it charges to other similar clients,
noting that the sub-advisory fee rate is generally lower than the fee rate
charged by the Sub-Advisor to other similar clients. In addition, the Board
reviewed data prepared by Lipper Inc. ("Lipper"), an independent source, showing
the advisory fees and expense ratios of the Fund as compared to the advisory
fees and expense ratios of an expense peer group selected by Lipper and similar
data from the Advisor for a separate peer group selected by the Advisor. The
Board noted that the Lipper peer group included only two funds and that the
Lipper and Advisor peer groups did not include any overlapping peer funds. The
Board discussed with representatives of the Advisor the limitations in creating
a relevant peer group for the Fund, including that (i) the Fund is unique in its
composition, which makes assembling peers with similar strategies and asset mix
difficult; (ii) peer funds may use different amounts and types of leverage which
have different costs associated with them or may use no leverage; and (iii) most
peer funds do not employ an advisor/sub-advisor management structure. The Board
took these limitations into account in considering the peer data. The Board
noted that Lipper changed the category in which it classified the Fund from
Sector Equity Funds to Natural Resources Funds between 2013 and 2014. In
reviewing the peer data, the Board noted that the Fund's contractual advisory
fee was equal to the median of the Lipper peer group.

The Board also considered performance information for the Fund, noting that the
performance information included the Fund's quarterly performance report, which
is part of the process that the Board has established for monitoring the Fund's
performance and portfolio risk on an ongoing basis. The Board determined that
this process continues to be effective for reviewing the Fund's performance. In
addition to the Board's ongoing review of performance, the Board also received
data prepared by Lipper comparing the Fund's performance to a performance

                         NOVEMBER 30, 2014 (UNAUDITED)


peer universe selected by Lipper and to a blended benchmark. In reviewing the
Fund's performance as compared to the performance of the Lipper performance peer
universe, the Board took into account the limitations described above with
respect to creating a relevant peer group for the Fund. The Board also
considered the Fund's dividend yield as of March 31, 2014 and information
provided by the Advisor on the Fund's leverage, including that leverage was
accretive to the Fund's total return in 2013. In addition, the Board compared
the Fund's premium/discount over the past eight quarters to the average and
median premium/discount of the Advisor peer group over the same period and
considered the factors that may impact a fund's premium/discount.

On the basis of all the information provided on the fees, expenses and
performance of the Fund, the Board concluded that the advisory and sub-advisory
fees were reasonable and appropriate in light of the nature, extent and quality
of services provided by the Advisor and Sub-Advisor under the Agreements.

The Board noted that the Advisor has continued to invest in personnel and
infrastructure and considered whether fee levels reflect any economies of scale
for the benefit of shareholders. The Board determined that due to the Fund's
closed-end structure, the potential for realization of economies of scale as
Fund assets grow was not a material factor to be considered. The Board also
considered the costs of the services provided and profits realized by the
Advisor from serving as investment advisor to the Fund for the twelve months
ended December 31, 2013, as well as product-line profitability data for the same
period, as set forth in the materials provided to the Board. The Board noted the
inherent limitations in the profitability analysis, and concluded that the
Advisor's estimated profitability appeared to be not excessive in light of the
services provided to the Fund. In addition, the Board considered fall-out
benefits described by the Advisor that may be realized from its relationship
with the Fund, including the Advisor's compensation for fund reporting services
pursuant to a separate Fund Reporting Services Agreement. The Board considered
the ownership interest of an affiliate of the Advisor in the Sub-Advisor and
potential fall-out benefits to the Advisor from such ownership interest.

The Board considered that the Sub-Advisor's investment services expenses are
primarily fixed, and that the Sub-Advisor has made recent investments in
infrastructure and personnel. The Board considered that the sub advisory fee
rate was negotiated at arm's length between the Advisor and the Sub-Advisor. The
Board also considered data provided by the Sub-Advisor as to the profitability
of the Sub-Advisory Agreement to the Sub-Advisor. The Board noted the inherent
limitations in the profitability analysis and concluded that the profitability
analysis for the Advisor was more relevant, although the profitability of the
Sub-Advisory Agreement appeared to be not excessive in light of the services
provided to the Fund. The Board considered fall-out benefits realized by the
Sub-Advisor from its relationship with the Fund, including soft-dollar
arrangements, and considered a summary of such arrangements. The Board also
considered the potential fall-out benefits to the Sub-Advisor from the ownership
interest of the Advisor's affiliate in the Sub-Advisor.

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


                                                                         Page 27

ITEM 2. CODE OF ETHICS.

(a)   The registrant, as of the end of the period covered by this report, has
      adopted a code of ethics that applies to the registrant's principal
      executive officer, principal financial officer, principal accounting

      party.

(c)   There have been no amendments, during the period covered by this report,
      to a provision of the code of ethics that applies to the registrant's
      principal executive officer, principal financial officer, principal
      accounting officer or controller, or persons performing similar functions,

(d)   The registrant has not granted any waivers, including an implicit waiver,
      from a provision of the code of ethics that applies to the registrant's

      regardless of whether these individuals are employed by the registrant or
      a third party, that relates to one or more of the items set forth in
      paragraph (b) of this item's instructions.


ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

As of the end of the period covered by the report, the Registrant's board of
trustees has determined that Thomas R. Kadlec and Robert F. Keith are qualified

that each of them is "independent," as defined by Item 3 of Form N-CSR.


ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

      (a) Audit Fees (Registrant) -- The aggregate fees billed for each of the
last two fiscal years for professional services rendered by the principal
accountant for the audit of the Registrant's annual financial statements or
services that are normally provided by the accountant in connection with
statutory and regulatory filings or engagements for those fiscal years were
$44,000 for the fiscal year ended November 30, 2013 and $44,000 for the fiscal
year ended November 30, 2014.

      (b) Audit-Related Fees (Registrant) -- The aggregate fees billed in each
of the last two fiscal years for assurance and related services by the principal

fiscal year ended November 30, 2014.

      Audit-Related Fees (Investment Adviser) -- The aggregate fees billed in
each of the last two fiscal years for assurance and related services by the

of the registrant's financial statements and are not reported under paragraph
(a) of this Item were $0 for the fiscal year ended November 30, 2013 and $0 for
the fiscal year ended November 30, 2014.

      (c) Tax Fees (Registrant) -- The aggregate fees billed in each of the last

through (c) of this Item were $0 for the fiscal year ended November 30, 2013 and

      All Other Fees (Investment Adviser) -- The aggregate fees billed in each

      (e)(1) Disclose the audit committee's pre-approval policies and procedures
described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

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

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

      (e)(2) The percentage of services described in each of paragraphs (b)
through (d) for the Registrant and the Registrant's investment adviser of this
Item that were approved by the audit committee pursuant to the pre-approval
exceptions included in paragraph (c)(7)(i)(c) or paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X are as follows:

                          (b)  0%
                          (c)  0%
                          (d)  0%

      (f) The percentage of hours expended on the principal accountant's
engagement to audit the registrant's financial statements for the most recent
fiscal year that were attributed to work performed by persons other than the
principal accountant's full-time, permanent employees was less than fifty
percent.

      (g) The aggregate non-audit fees billed by the registrant's accountant for
services rendered to the Registrant, and rendered to the Registrant's investment
adviser (not including any sub-adviser whose role is primarily portfolio
management and is subcontracted with or overseen by another investment adviser),
and any entity controlling, controlled by, or under common control with the
adviser that provides ongoing services to the Registrant for the fiscal year
ended November 30, 2013 were $6,300 for the Registrant and $3,000 for the
Registrant's investment adviser, and for the fiscal year ended November 30, 2014
were $6,300 for the registrant and $43,500 for the Registrant's investment
adviser.

      (h) The Registrant's audit committee of its Board of Trustees has
determined that the provision of non-audit services that were rendered to the
Registrant's investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
Registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X is compatible with maintaining the principal accountant's
independence.


ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

The Registrant has a separately designated audit committee consisting of all the
independent trustees of the Registrant. The members of the audit committee are:
Thomas R. Kadlec, Niel B. Nielson, Richard E. Erickson and Robert F. Keith.

ITEM 6. INVESTMENTS.

(a)   Schedule of Investments in securities of unaffiliated issuers as of the
      close of the reporting period is included as part of the report to
      shareholders filed under Item 1 of this form.

(b)   Not applicable.


ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

                      PROXY VOTING POLICIES AND PROCEDURES

If an adviser exercises voting authority with respect to client securities,
Advisers Act Rule 206(4)-6 requires the adviser to adopt and implement written
policies and procedures reasonably designed to ensure that client securities are
voted in the best interest of the client. This is consistent with legal
interpretations which hold that an adviser's fiduciary duty includes handling
the voting of proxies on securities held in client accounts over which the
adviser exercises investment or voting discretion, in a manner consistent with
the best interest of the client.

Absent unusual circumstances, EIP exercises voting authority with respect to
securities held in client accounts pursuant to provisions in its advisory
agreements. Accordingly, EIP has adopted these policies and procedures with the
aim of meeting the following requirements of Rule 206(4)-6:

      o     ensuring that proxies are voted in the best interest of clients;

      o     addressing material conflicts that may arise between EIP's interests
            and those of its clients in the voting of proxies;

      o     disclosing to clients how they may obtain information on how EIP
            voted proxies with respect to the client's securities;

      o     describing to clients EIP's proxy voting policies and procedures
            and, upon request, furnishing a copy of the policies and procedures
            to the requesting client.

               ENGAGEMENT OF INSTITUTIONAL SHAREHOLDER SERVICES INC.

      With the aim of ensuring that proxies are voted in the best interest of
EIP clients, EIP has engaged Institutional Shareholder Services Inc. ("ISS"),
formerly known as ISS, as its independent proxy voting service to provide EIP
with proxy voting recommendations, as well as to handle the administrative
mechanics of proxy voting. EIP has directed ISS to utilize its Proxy Voting
Guidelines in making recommendations to vote, as those guidelines may be amended
from time to time.

                     CONFLICTS OF INTEREST IN PROXY VOTING

      There may be instances where EIP's interests conflict, or appear to
conflict, with client interests in the voting of proxies. For example, EIP may
provide services to, or have an investor who is a senior member of, a company
whose management is soliciting proxies. There may be a concern that EIP would
vote in favor of management because of its relationship with the company or a
senior officer. Or, for example, EIP (or its senior executive officers) may have
business or personal relationships with corporate directors or candidates for
directorship.

      EIP addresses these conflicts or appearances of conflicts by ensuring that
proxies are voted in accordance with the recommendations made by RiskMetrics, an
independent third party proxy voting service. As previously noted, in most
cases, proxies will be voted in accordance with RiskMetrics's own pre-existing
proxy voting guidelines.

                      DISCLOSURE ON HOW PROXIES WERE VOTED

      EIP will disclose to clients in its Form ADV how clients can obtain
information on how their proxies were voted, by contacting EIP at its office in
Westport, CT. EIP will also disclose in the ADV a summary of these proxy voting
policies and procedures and that upon request, clients will be furnished a full
copy of these policies and procedures.

      It is the responsibility of the CCO to ensure that any requests made by
clients for proxy voting information are responded to in a timely fashion and
that a record of requests and responses are maintained in EIP's books and
records.

                                PROXY MATERIALS

      EIP personnel will instruct custodians to forward to RiskMetrics all proxy
materials received on securities held in EIP client accounts.

                                  LIMITATIONS

      In certain circumstances, where EIP has determined that it is consistent
with the client's best interest, EIP will not take steps to ensure that proxies
are voted on securities in the client's account. The following are circumstances
where this may occur:

      *Limited Value: Proxies will not be required to be voted on securities in
a client's account if the value of the client's economic interest in the
securities is indeterminable or insignificant (less than $1,000). Proxies will
also not be required to be voted for any securities that are no longer held by
the client's account.

      *Securities Lending Program: When securities are out on loan, they are
transferred into the borrower's name and are voted by the borrower, in its
discretion. In most cases, EIP will not take steps to see that loaned securities
are voted. However, where EIP determines that a proxy vote, or other shareholder
action, is materially important to the client's account, EIP will make a good
faith effort to recall the security for purposes of voting, understanding that
in certain cases, the attempt to recall the security may not be effective in
time for voting deadlines to be met.

      *Unjustifiable Costs: In certain circumstances, after doing a cost-benefit
analysis, EIP may choose not to vote where the cost of voting a client's proxy
would exceed any anticipated benefits to the client of the proxy proposal.

      OVERSIGHT OF POLICY The CCO is responsible for overseeing these proxy
voting policies and procedures. In addition, the CCO will review these policies
and procedures not less than annually with a view to determining whether their
implementation has been effective and that they are operating as intended and in
such a fashion as to maintaining EIP's compliance with all applicable
requirements.

                            RECORDKEEPING ON PROXIES

      In it the responsibility of EIP's CCO to ensure that the following proxy
voting records are maintained:

      o     a copy of EIP's proxy voting policies and procedures;

      o     a copy of all proxy statements received on securities in client
            accounts (EIP may rely on RiskMetrics or the SEC's EDGAR system to
            satisfy this requirement);

      o     a record of each vote cast on behalf of a client (EIP relies on
            RiskMetrics to satisfy this requirement);

      o     a copy of any document prepared by EIP that was material to making a
            voting decision or that memorializes the basis for that decision;

      o     a copy of each written client request for information on how proxies
            were voted on the client's behalf or for a copy of EIP's proxy
            voting policies and procedures, and

      o     a copy of any written response to any client request for information
            on how proxies were voted on their behalf or furnishing a copy of
            EIP's proxy voting policies and procedures.

      The CCO will see that these books and records are made and maintained in
accordance with the requirements and time periods provided in Rule 204-2 of the
Advisers Act.

      For any registered investment companies advised by EIP, votes made on its
behalf will be stored electronically or otherwise recorded so that they are
available for preparation of the Form N-PX, Annual Report of Proxy Voting Record
of Registered Management Investment Company.

POTENTIAL CONFLICTS OF INTERESTS

      Besides the Funds, the Energy Income Partners, LLC ("EIP") also serves as
a sub-advisor to two closed-end management investment companies other than the
Funds, an actively managed exchange-traded fund (ETF), a sleeve of an ETF and a
sleeve of a series of a variable insurance trust. EIP also serves as investment
advisor to an open-end privately offered management investment company, and to
three private investment funds (the "Private Funds"). These three Private Funds
charge a performance fee. In addition, EIP advises separately managed accounts,
one of which has a performance fee, and provides its model portfolio to unified
managed accounts.

      EIP has written policies and procedures regarding Order Aggregation and
Allocation to ensure that all accounts are treated fairly and equitably and that
no account is at a disadvantage. EIP will generally execute client transactions
on an aggregated basis when the Firm believes that to do so will allow it to
obtain best execution and to negotiate more favorable commission rates or avoid
certain transaction costs that might have otherwise been paid had such orders
been placed independently. EIP's ability to implement this may be limited by an
account's custodian, directed brokerage arrangements or other constraints
limiting EIP's use of a common executing broker.

      An aggregated order may be allocated on a basis different from that
specified herein provided that all clients receive fair and equitable treatment
and there is a legitimate reason for the different allocation. Reasons for
deviation may include (but are not limited to): a client's investment guidelines
and restrictions, available cash, liquidity or legal reasons, and to avoid
odd-lots or in cases when a normal allocation would result in a de minimis
allocation to one or more clients.

      Notwithstanding the above, due to differing tax ramifications and
compliance ratios, as well as dissimilar risk constraints and tolerances,
accounts with similar investment mandates may trade the same securities at
differing points in time. Additionally, for the reasons noted above, certain
accounts, including funds in which EIP, its affiliates and/or employees ("EIP
Funds") have a financial interest, may trade separately from other accounts and
participate in transactions which are deemed to be inappropriate for other
accounts with similar investment mandates. Further, during periods in which EIP
intends to trade the same securities across multiple accounts, transactions for
those accounts that must be traded through specific brokers and/or platforms
will often be executed after those for accounts over which EIP exercises full
brokerage discretion, including the EIP Funds.

(A)(3) COMPENSATION STRUCTURE OF PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBERS

Information provided as of November 30, 2014.

The portfolio managers are compensated by a competitive minimum base salary and
share in the profits of EIP based on their EIP ownership. EIP's profits are
based on the assets under management and performance. While a portion of the
portfolio managers' compensation is tied to the performance through performance
fees earned through the Private Funds' performance, the portfolio managers are
not incentivized to take undue risk in circumstances when the Private Funds'
performance lags because their performance fee structures may sometimes have a
high watermark or are subject to a hurdle rate. Moreover, the portfolio managers
are the principal owners of EIP and are incentivized to maximize the long-term
performance of all of its clients, including the Funds, other funds and managed
accounts.

The compensation of the EIP team members is determined according to prevailing
rates within the industry for similar positions. EIP wishes to attract, retain
and reward high quality personnel through a competitive compensation package.

      amended (17 CFR 240.13a-15(b) or 240.15d-15(b)).

(b)   There were no changes in the Registrant's internal control over financial
      reporting (as defined in Rule 30a-3(d) under the 1940 Act (17 CFR
      270.30a-3(d)) that occurred during the Registrant's second fiscal quarter
      of the period covered by this report that has materially affected, or is
      reasonably likely to materially affect, the Registrant's internal control
      over financial reporting.

1     The Fund has received exemptive relief from the Securities and Exchange
      Commission which permits the Fund to make periodic distributions of
      long-term capital gains as frequently as monthly each tax year. The relief
      is conditioned, in part, on an undertaking by the Fund to make the
      disclosures to the holders of the Fund's common shares, in addition to the
      information required by Section 19(a) of the 1940 Act and Rule 19a-1
      thereunder. The Fund is likewise obligated to file with the SEC the
      information contained in any such notice to shareholders. In that regard,
      attached as an exhibit to this filing is a copy of such notice made during
      the period.
