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
any series of First Trust Exchange-Traded Fund (the "Trust") described in this
report (each such series is referred to as a "Fund" and collectively, as the
"Funds") to be materially different from any future results, performance or
achievements expressed or implied by the forward-looking statements. When

place undue reliance on these forward-looking statements, which reflect the
judgment of the Advisor and its representatives only as of the date hereof. We

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its
investment objective. Each 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 a Fund. See "Risk
Considerations" in the Additional Information Section of this report for a
discussion of other risks of investing in the Funds.

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
www.ftportfolios.com or speak with your financial advisor. Investment returns,
net asset value and share price will fluctuate and Fund shares, when sold, may
be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund
performance on each Fund's webpage at www.ftportfolios.com.

SHAREHOLDER LETTER
--------------------------------------------------------------------------------

                        FIRST TRUST EXCHANGE-TRADED FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                               DECEMBER 31, 2017

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Exchange-Traded Fund which contains detailed information about your investment
for the twelve months ended December 31, 2017, including a market overview and a
performance analysis for the period. We encourage you to read this report
carefully and discuss it with your financial advisor.

This was a very strong year for U.S. markets. The three major indices--the S&P
500(R) Index, the Dow Jones Industrial Average and the Nasdaq posted their best
performance since 2013. And there was more good news for Wall Street:

      o     The S&P 500(R) achieved something it had not previously finishing
            2017 with 12 months of gains;

      o     The Dow Jones realized a milestone as well closing above 24,000 for
            the first time ever on November 30; and

      o     The Nasdaq set a record by having 11 months of gains in 2017 (June
            was the only down month, and by just 0.86%).

World markets were also strong in 2017. According to the MSCI AC World Index,
which captures all sources of equity returns in 23 developed and 24 emerging
markets, world stocks rose every month in 2017. The value of public companies on
global stock markets grew by $12.4 trillion during the year.

In 2017, stocks benefitted from increased global demand, growth in corporate
profits (especially technology stocks) and an accommodative Federal Reserve. The
housing market in the United States continues to grow due to a strong job
market, low interest rates and tight inventory. As the year came to a close,
President Trump signed the tax reform package, called the "Tax Cuts and Jobs
Act," which was seen as a promise kept by then-candidate Trump to accomplish
sweeping reform. It is hoped this tax reform will boost economic activity to
greater highs.

At First Trust, we are optimistic about the U.S. economy. We also continue to
believe that you should invest for the long term and be prepared for market
volatility, which can happen at any time. How can you do this? By keeping
current on your portfolio and investing goals by speaking regularly with your
investment professional. It's important to keep in mind that past performance of
the U.S. and global stock markets or investment products can never guarantee
future results. As we've said before, markets go up and they also go down, but
savvy investors are prepared for either through careful attention to their
portfolios and investment goals.

Thank you for giving First Trust the opportunity to be a part of your financial
plan through your investment. We value our relationship with you and will report
on your investment again in six months.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

MARKET OVERVIEW
--------------------------------------------------------------------------------

                        FIRST TRUST EXCHANGE-TRADED FUND
                                 ANNUAL REPORT
                         DECEMBER 31, 2017 (UNAUDITED)

ROBERT F. CAREY, CFA
SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST
FIRST TRUST ADVISORS L.P.

Mr. Carey is responsible for the overall management of research and analysis of
the First Trust product line. Mr. Carey has over 25 years of experience as an
Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial
Analyst ("CFA") designation. He is a graduate of the University of Illinois at
Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment
Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a
guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been
quoted by several publications, including The Wall Street Journal, The Wall
Street Reporter, Bloomberg News Service, and Registered Rep.

STATE OF THE ECONOMY/INVESTING

At the midpoint of 2017, House Speaker Paul Ryan stated that he did not think
that the U.S. economy could achieve a 3% gross domestic product ("GDP") growth
rate without passing tax reform legislation. The Tax Cuts and Jobs Act was
signed into law by President Trump on December 22, 2017. One of the main goals
of cutting taxes, both corporate and individual, is to try and boost economic
activity in the U.S. It is true that real GDP growth has topped the 3.0% mark on
an annualized basis the past two quarters (3.1% in the second quarter and 3.2%
in the third quarter), but growth has only averaged 2.2% in the current
recovery, which commenced in the third quarter of 2009, according to data from
the Bureau of Economic Analysis. While it will likely take some time to
determine how effective lower tax rates will be in stimulating economic growth,
particularly the cut from 35% to 21% on the federal tax rate for corporations,
the concept of tax cuts seems to have been well-received by investors since
Trump was elected more than a year ago, in our opinion.

Both small and large companies in the U.S. seem optimistic looking ahead. The
National Federation of Independent Business ("NFIB") reported that its Small
Business Optimism Index hit 107.5 in November, the second-highest reading in its
44-year history, according to its own release. The all-time high was 108.0, set
in September 1983. The NFIB noted that "small business owners are exuberant
about the economy and are ready to lead the U.S. economy in a period of robust
growth." Chief Executive's CEO Confidence Index in Business Conditions 12 Months
Out just registered its second most optimistic year (7.08 out of 10) since the
index commenced in 2003, according to its own release. The highest mark ever
achieved for a calendar year was 7.47 in 2004. The monthly survey of 267 CEOs
revealed that two-thirds of those polled plan to add to their workforce in 2018,
while only 5% forecast a decrease in headcount. CEOs are also expecting to
increase both profitability and revenue in 2018.

ETFGI, an industry research group, reported that total assets invested in
exchange-traded funds ("ETFs") and other exchange-traded products ("ETPs")
listed globally reached an all-time high of $4.83 trillion at the close of 2017,
according to its own release. Total assets invested in ETFs and ETPs listed in
the U.S. reached a record high of $3.42 trillion.

U.S. STOCKS AND BONDS

In 2017, three of the major U.S. stock indices posted double-digit returns. The
S&P 500(R) Index, S&P MidCap 400(R) Index and S&P SmallCap 600(R) Index posted
total returns of 21.83%, 16.24%, and 13.23%, respectively, according to
Bloomberg. Nine of the 11 major S&P 500(R) Index sectors posted positive total
returns. The top-performing sectors were Information Technology, Materials and
Consumer Discretionary, up 38.83%, 23.84% and 22.98%, respectively, on a total
return basis. The two sectors that posted losses were Energy and
Telecommunication Services, down 1.25% and 1.01%, respectively. In general,
cyclical areas of the stock market outperformed non-cyclicals in 2017, an
indication that investors are optimistic about U.S. economic growth moving
forward.

The Federal Reserve ("the Fed") raised the federal funds target rate (upper
bound) three times, from 0.75% to 1.50%, in 2017. It is poised to hike rates
three times in 2018, according to CNBC. The Fed has already raised this rate
five times, dating back to its first hike on December 16, 2015. If the Fed
tightens three times in 2018, the rate will likely hit 2.25%, assuming 25 basis
points per hike. For comparative purposes, the target rate averaged 2.68% for
the 25-year period ended December 29, 2017, according to Bloomberg. The highest
level it reached over that period was 6.50% on May 16, 2000. So while this key
benchmark lending rate is rising, it is still low by historical standards. The
projected bump up in interest rates would not likely derail the bull market in
stocks, but it could put some downward pressure on bond prices by pushing bond
yields higher, in our opinion.

In the U.S. bond market, the top-performing major debt group was high yield
corporate bonds. The Bloomberg Barclays U.S. Corporate High Yield Index posted a
total return of 7.50% in 2017. The worst-performing debt group that we track was
Treasuries, though the group still generated a positive return. The Bloomberg
Barclays U.S. Treasury: Intermediate Index posted a total return of 1.14%. The
yield on the benchmark 10-Year Treasury note (T-note) declined by four basis
points to 2.41% in 2017, according to Bloomberg. The average yield on the
10-year T-note was 2.58% for the 10-year period ended December 29, 2017.

FOREIGN STOCKS AND BONDS

The U.S. dollar declined by 9.87% against a basket of major currencies in 2017,
as measured by the U.S. Dollar Index (DXY). With respect to U.S. investors, a
weaker U.S. dollar can positively impact returns on foreign securities.

The Bloomberg Barclays EM Hard Currency Aggregate Index of emerging markets debt
posted a total return of 9.61% (USD), while the Bloomberg Barclays Global
Aggregate Index of higher quality debt rose 7.39% (USD) in 2017. The MSCI Daily
Total Return Net Emerging Markets Index of stocks posted a total return of
37.28% (USD), while the MSCI Daily Total Return Net World Index (excluding the
U.S.) posted a total return of 24.21% (USD) in 2017.

PERFORMANCE REVIEW

The Fund generated a net asset value ("NAV") return of 8.44% during the 12-month
period covered by this report. During the same period, the Russell 2000(R) Index
("benchmark") generated a return of 14.65%. The Financials sector was given the
highest allocation in the Fund with a 44.3% weighting. This sector had a modest
return of 5.2% leading to a 1.8% contribution. The largest contributing sector
to the Fund's return was the Industrials sector with a 2.1% contribution, which
stems from its 14.8% allocation and 15.7% return. The Telecommunication Services
sector was the worst performing sector with a -22.3% return and also the
smallest weighted sector at 0.4%, which minimized its total impact to the Fund
to only -0.2%. On a relative basis, the Fund underperformed the benchmark. The
Fund's 26.2% larger allocation to the Financials sector created -2.5% of
relative drag. The Fund's holdings within the Consumer Discretionary sector also
created -1.6% of relative drag as the Fund underperformed this sector by 9.0%.
Underperformance of 1.0% was reversed by the Fund giving less weighting to the
poor performing Energy sector securities.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

them. The Index consists of the top 100 stocks, based on dividend yield, in the
Morningstar(R) U.S. Market Index that have been selected through the application
of Morningstar, Inc.'s proprietary multi-step screening process. The Index is
rebalanced annually in June. The Fund's shares are listed for trading on the
NYSE Arca. The first day of secondary market trading in shares of the Fund was

PERFORMANCE REVIEW

The Fund generated a NAV return of 11.93% during the 12-month period covered by
this report. During the same period, the S&P 500(R) Index ("benchmark")
generated a return of 21.83%. The Fund's largest allocation was in the Consumer
Staples sector with a 17.2% weighting. This sector was also the greatest
contributing sector to the Fund's return with a 3.1% contribution and 17.3%
return. The top performing sector in the Fund was the Materials sector with a
32.2% return. The least contributing sector was the Telecommunication Services
sector with a -0.5% contribution, which stems from its 16.1% allocation and
-0.5% return. On a relative basis, the Fund underperformed the benchmark. The
primary cause of the underperformance is attributable to the Fund
over-allocating the Telecommunication Services sector by 13.9%, leading to -3.5%
of relative drag. The Fund's holdings within the Energy sector reversed 1.4% of
underperformance as the Fund over-allocated and outperformed the benchmark by
2.9% and 6.8%, respectively, in this sector.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST US EQUITY OPPORTUNITIES ETF (FPX)

The First Trust US Equity Opportunities ETF (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the IPOX(R)-100 U.S. Index (the
"Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Index. The
Index is an applied market-cap weighted price index measuring the performance of
the top U.S. companies ranked quarterly by market capitalization in the IPOX(R)
U.S. Composite Index, a sub-index of the IPOX(R) Global Composite Index. The
Index utilizes a 10% capping on all constituents and includes the 100 largest
public offerings ("IPOs") in the IPOX(R) U.S. Composite Index, adjusted for
liquidity. In general, eligible constituents are added on the sixth day of
trading and remain eligible to be included in the Index for approximately four
years. The Index includes the securities of small, mid and large companies. The
Fund's shares are listed for trading on the NYSE Arca. The first day of
secondary market trading in shares of the Fund was April 13, 2006.

PERFORMANCE REVIEW

The Fund generated a NAV return of 26.96% during the 12-month period covered by
this report. During the same period, the Russell 3000(R) Index ("benchmark")
generated a return of 21.13%. The Information Technology sector was the highest
allocated sector in the Fund with a 26.8% weighting. This sector had a 42.9%
return, which led to a 9.9% contribution to the Fund's return. It was the
Materials sector which had the top return of 44.6%. The Fund's performance was
impacted by -0.8% due to the Fund's holdings within the Energy sector which had
2.4% allocation and -26.9% return. On a relative basis, the Fund outperformed
the benchmark. The primary cause of the outperformance is due to the Fund
outperforming the benchmark within the Consumer Discretionary sector by 14.3%,
creating 2.3% of relative outperformance. The Fund's holdings within the
Consumer Staples sector reversed -1.7% of underperformance as the benchmark
outperformed the Fund by 6.9%.

not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST NYSE ARCA BIOTECHNOLOGY INDEX FUND (FBT)

The First Trust NYSE Arca Biotechnology Index Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the NYSE Arca Biotechnology Index(SM)
(the "Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Index. The
Index is an equal dollar-weighted index designed to measure the performance of a
cross section of companies in the biotechnology industry that are primarily
involved in the use of biological processes to develop products or provide
services. Such processes include, but are not limited to, recombinant DNA
technology, molecular biology, genetic engineering, monoclonal antibody-based
technology, lipid/liposome technology and genomics. This Index is rebalanced
quarterly based on closing prices on the third Friday in January, April, July
and October to ensure that each component stock continues to represent
approximately equal weight in the Index. The Fund's shares are listed for
trading on the NYSE Arca. The first day of secondary market trading in shares of
the Fund was June 23, 2006.

FIRST TRUST DOW JONES INTERNET INDEX FUND (FDN)

The First Trust Dow Jones Internet Index Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Dow Jones Internet Composite
Index(SM) (the "Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in common stocks that comprise the
Index. The Index represents companies that generate the majority of their
revenues via the Internet. The Index is designed to include only companies whose
primary focus is Internet-related. To be eligible for inclusion in the Index, a
company must generate at least 50% of its revenue from Internet commerce or
services. Internet commerce companies are defined as those that derive the
majority of their revenues from providing goods and services through an open
network, whereas Internet services companies are defined as those that derive
the majority of their revenues from providing access to the Internet or
providing services to people using the Internet. The Fund's shares are listed
for trading on the NYSE Arca. The first day of secondary market trading in
shares of the Fund was June 23, 2006.

PERFORMANCE REVIEW

The Fund generated a NAV return of 37.62% during the 12-month period covered by
this report. During the same period, the S&P Composite 1500(R) Information
Technology Index ("benchmark") generated a return of 37.29%. The Fund was mainly
comprised of Information Technology securities (69.5% allocation), which had a
38.5% return and 26.7% contribution, and Consumer Discretionary securities
(19.9% allocation), which had a 40.1% return and 8.1% contribution. On a
relative basis, the Fund outperformed the benchmark. The benchmark did not have
any exposure to Consumer Discretionary securities such as Amazon.com, Inc.,
Netflix, Inc. or Groupon, Inc., which led to 0.5% of outperformance. The Fund's
Information Technology sector holdings led to 0.7% of outperformance as the Fund
outperformed the benchmark by 1.0%. Securities like E*TRADE Financial Corp. and
TD Ameritrade Holding Corp., which are categorized as Diversified Financials by
GICS, led to -0.2% of relative drag as the benchmark did not have any exposure
to these less than average performing securities.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST CAPITAL STRENGTH ETF (FTCS)

The First Trust Capital Strength ETF (the "Fund") seeks investment results that
correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called The Capital Strength Index(TM) (the
"Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Index. In
constructing the Index, NASDAQ begins with the largest 500 U.S. companies
included in the NASDAQ US Benchmark Index and excludes (i) companies with less
than $1 billion in cash and short term investments; (ii) companies with
long-term debt are divided by the market capitalization greater than 30%; and
(iii) companies with return on equity less than 15%. NASDAQ then ranks all
remaining stocks in the universe by one-year and three-month daily volatility
(one-year and three-month daily volatility factors are equally weighted), and
selects the top 50 companies with the lowest combined volatility score, subject
to a maximum weight of 30% from any one of the ten Industry Classification
Benchmark industries. The stocks in the Index are equally weighted initially and
on each reconstituting and rebalancing effective date. The Fund's shares are
listed for trading on the Nasdaq. The first day of secondary market trading in
shares of the Fund was July 11, 2006.

      the Fund until May 1, 2018.

PERFORMANCE REVIEW

The Fund generated a NAV return of 26.49% during the 12-month period covered by
this report. During the same period, the S&P 500 Value Index ("benchmark")
generated a return of 15.36%. The Fund's largest sector allocation was the
Information Technology sector with a 30.3% allocation. This sector had a 27.7%
return and 8.5% contribution. The top performing sector in the Fund was the
Financials sector with a 49.7% return. This sector was given a smaller weighting
of 3.6%, which capped the sector impact to the Fund's return to only 1.7%. The
Fund's holdings amongst Consumer Discretionary sector were the worst performing
securities with a 11.2% return. On a relative basis, the Fund outperformed the
benchmark. The primary cause of the outperformance is attributable to the Fund
overweighting and outperforming the benchmark amongst Industrials sector
securities by 14.2% and 16.9%, respectively, creating 3.7% of outperformance.
Outperformance of 0.7% was reversed due to the Fund underperforming the
benchmark amongst Consumer Discretionary sector.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST VALUE LINE(R) DIVIDEND INDEX FUND (FVD)

The First Trust Value Line(R) Dividend Index Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Value Line(R) Dividend Index (the
"Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Index. The
Index is designed to objectively identify and select those stocks from the
universe of stocks which Value Line Publishing LLC gives a Safety(TM) Ranking of
#1 or #2 in the Value Line(R) Safety(TM) Ranking System and have the potential
to pay above-average dividends and achieve capital appreciation. The Index is
rebalanced on a monthly basis. The Fund's shares are listed for trading on the
NYSE Arca.

      On December 15, 2006, the Fund acquired the assets and adopted the
      financial and performance history of First Trust Value Line(R) Dividend
      Fund (the "Predecessor FVD Fund," a closed-end fund), which had an
      inception date of August 19, 2003. The inception date total returns at net
      asset value ("NAV") include the sales load of $0.675 per share on the
      initial offering. The investment goals, strategies and policies of the
      Fund are substantially similar to those of the Predecessor FVD Fund. The
      inception date of the Index was July 3, 2006. Returns for the Index are
      only disclosed for those periods in which the Index was in existence for
      the entire period. The cumulative total returns for the period from the
      reorganization date (December 15, 2006) through period end (December 31,
      2017) were 146.46% and 147.80% at NAV and Market Value, respectively. That
      compares to an Index return of 168.76% for the same period. The average
      annual total returns for the period from the reorganization date (December
      15, 2006) through period end (December 31, 2017) were 8.51% and 8.56% at
      NAV and Market Value, respectively. That compares to an Index return of
      9.37% for the same period.

      NAV and Market Value returns assume that all distributions have been
      reinvested in the Fund at NAV and Market Value, respectively. Prior to
      December 15, 2006, NAV and Market Value returns assumed that all
      distributions were reinvested at prices obtained by the Dividend

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

      On June 15, 2007, the Fund acquired the assets and adopted the financial
      and performance history of First Trust Value Line(R) 100 Fund (the
      "Predecessor FVL Fund," a closed-end fund), which had an inception date of
      June 12, 2003. The inception date total returns at NAV include the sales
      load of $0.675 per share on the initial offering. The investment goals,
      strategies and policies of the Fund are substantially similar to those of
      the Predecessor FVL Fund. The inception date of the Index was January 16,
      2007. Returns for the Index are only disclosed for those periods in which
      the Index was in existence for the entire period. The cumulative total
      returns for the period from the reorganization date (June 15, 2007)
      through period end (December 31, 2017) were 45.26% and 45.33% at NAV and
      Market Value, respectively. That compares to an Index return of 59.57% for
      that same period. The average annual total returns for the period from the
      reorganization date (June 15, 2007) through period end (December 31, 2017)
      were 3.60% and 3.61% at NAV and Market Value, respectively. That compares
      to an Index return of 4.53% for the same period.

      NAV and Market Value returns assume that all distributions have been
      reinvested in the Fund at NAV and Market Value, respectively. Prior to
      June 15, 2007, NAV and Market Value returns assumed that all distributions
      were reinvested at prices obtained by the Dividend Reinvestment Plan of
      the Predecessor FVL Fund and the price used to calculate Market Value
      return was the AMEX (now known as the NYSE MKT) closing market price of
      the Predecessor FVL Fund.

      * Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for some of the
      entire periods.

(See Notes to Fund Performance Overview on page 20.)

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

Total returns for the periods since inception are calculated from the inception
date of each Fund. "Average annual total returns" represent the average annual
change in value of an investment over the periods indicated. "Cumulative total
returns" represent the total change in value of an investment over the periods
indicated. The total returns would have been lower if certain fees had not been
waived and expenses reimbursed by the Advisor.

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period from inception
to the first day of secondary market trading in shares of the Fund, the NAV of
each Fund is used as a proxy for the secondary market trading price to calculate
market returns. NAV and market returns assume that all distributions have been
reinvested in each Fund at NAV and Market Price, respectively.

An index is a statistical composite that tracks a specified financial market or
sector. Unlike each Fund, the indices do not actually hold a portfolio of
securities and therefore do not incur the expenses incurred by each Fund. These
expenses negatively impact the performance of each Fund. Also, market returns do
not include brokerage commissions that may be payable on secondary market
transactions. If brokerage commissions were included, market returns would be
lower. The total returns presented reflect the reinvestment of dividends on
securities in the indices. The returns presented do not reflect the deduction of
taxes that a shareholder would pay on Fund distributions or the redemption or
sale of Fund shares. The investment return and principal value of shares of each
Fund will vary with changes in market conditions. Shares of each Fund may be
worth more or less than their original cost when they are redeemed or sold in
the market. Each Fund's past performance is no guarantee of future performance.

FIRST TRUST EXCHANGE-TRADED FUND

UNDERSTANDING YOUR FUND EXPENSES
DECEMBER 31, 2017 (UNAUDITED)

As a shareholder of First Trust Dow Jones Select MicroCap Index Fund, First
Trust Morningstar Dividend Leaders Index Fund, First Trust US Equity
Opportunities ETF, First Trust NYSE Arca Biotechnology Index Fund, First Trust
Dow Jones Internet Index Fund, First Trust Capital Strength ETF, First Trust
Value Line(R) Dividend Index Fund or First Trust Value Line(R) 100
Exchange-Traded Fund (each a "Fund" and collectively, the "Funds"), you incur
two types of costs: (1) transaction costs; and (2) ongoing costs, including
management fees, distribution and/or service fees, if any, and other Fund
expenses. This Example is intended to help you understand your ongoing costs of
investing in the Funds and to compare these costs with the ongoing costs of
investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended December 31, 2017.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this six-month
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on each Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
each Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Funds and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)   Total return is calculated assuming an initial investment made at the net
      asset value at the beginning of the period, reinvestment of all
      distributions at net asset value during the period, and redemption at net
      asset value on the last day of the period. The returns presented do not
      reflect the deduction of taxes that a shareholder would pay on Fund
      distributions or the redemption or sale of Fund shares. Total return is
      calculated for the time period presented and is not annualized for periods
      of less than a year. The total returns would have been lower if certain
      fees had not been waived and expenses reimbursed by the investment
      advisor.

(b)   Portfolio turnover is calculated for the time period presented and is not
      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

      distributions or the redemption or sale of Fund shares. Total return is
      calculated for the time period presented and is not annualized for periods

(c)   The Fund received a payment from the Advisor in the amount of $95,996 in
      connection with a trade error, which represents $0.03 per share. Since the
      Advisor reimbursed the Fund, there was no effect on the Fund's total
      return.

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

                                1. ORGANIZATION

First Trust Exchange-Traded Fund (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on August 8,
2003, and is registered with the Securities and Exchange Commission ("SEC")
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty exchange-traded funds. This report covers
the eight funds listed below:

      First Trust Dow Jones Select MicroCap Index Fund - (NYSE Arca, Inc.
         ("NYSE Arca") ticker "FDM")
      First Trust Morningstar Dividend Leaders Index Fund - (NYSE Arca ticker
         "FDL")
      First Trust US Equity Opportunities ETF - (NYSE Arca ticker "FPX")
      First Trust NYSE Arca Biotechnology Index Fund - (NYSE Arca ticker "FBT")
      First Trust Dow Jones Internet Index Fund - (NYSE Arca ticker "FDN")
      First Trust Capital Strength ETF - (The Nasdaq Stock Market LLC ("Nasdaq")
          ticker "FTCS")
      First Trust Value Line Dividend Index Fund - (NYSE Arca ticker "FVD")
      First Trust Value Line(R) 100 Exchange-Traded Fund - (NYSE Arca ticker
         "FVL")

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Creation Units are generally issued and redeemed in-kind for
securities in which a Fund invests and, in certain circumstances, for cash, and
only to and from broker-dealers and large institutional investors that have
entered into participation agreements. Except when aggregated in Creation Units,
each Fund's shares are not redeemable securities. The investment objective of
each Fund is to seek investment results that correspond generally to the price
and yield (before the Fund's fees and expenses) of the following indices:

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Funds are each considered an investment company and follow accounting and
reporting guidance under Financial Accounting Standards Board Accounting
Standards Codification Topic 946, "Financial Services-Investment Companies." The
following is a summary of significant accounting policies consistently followed
by the Funds in the preparation of the financial statements. The preparation of
the financial statements in accordance with accounting principles generally
accepted in the United States of America ("U.S. GAAP") requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION

Each Fund's NAV is determined daily as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Each Fund's NAV is calculated by dividing the
value of all assets of each Fund (including accrued interest and dividends),
less all liabilities (including accrued expenses and dividends declared but
unpaid), by the total number of shares outstanding.

Each Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Funds'
investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Trust's Board of
Trustees, and in accordance with provisions of the 1940 Act. Investments valued
by the Advisor's Pricing Committee, if any, are footnoted as such in the
footnotes to the Portfolio of Investments. Each Fund's investments are valued as
follows:

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than
      one securities exchange are valued at the last sale price or official
      closing price, as applicable, at the close of the securities exchange
      representing the principal market for such securities.

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

      Securities traded in an over-the-counter market are fair valued at the
      mean of their most recent bid and asked price, if available, and otherwise
      at their closing bid price.

      Overnight repurchase agreements are valued at amortized cost when it
      represents the best estimate of fair value.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) for which a third-party pricing service is unable to provide a
market price; securities whose trading has been formally suspended; a security
whose market or fair value price is not available from a pre-established pricing
source; a security with respect to which an event has occurred that is likely to
materially affect the value of the security after the market has closed but
before the calculation of a Fund's NAV or make it difficult or impossible to
obtain a reliable market quotation; and a security whose price, as provided by
the third-party pricing service, does not reflect the security's fair value. As
a general principle, the current fair value of a security would appear to be the
amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

In addition, differences between the prices used to calculate a Fund's NAV and
the prices used by such Fund's corresponding index could result in a difference
between a Fund's performance and the performance of its underlying index.

The Funds are subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investment.


                                                                         Page 59

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of December 31, 2017, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

Withholding taxes and tax reclaims on foreign dividends have been provided for
in accordance with each Fund's understanding of the applicable country's tax
rules and rates.

Distributions received from a Fund's investments in real estate investment trust
("REITs") may be comprised of return of capital, capital gains and income. The
actual character of the amounts received during the year is not known until
after the REITs' fiscal year end. A Fund records the character of distributions
received from REITs during the year based on estimates available. The
characterization of distributions received by a Fund may be subsequently revised
based on information received from the REITs after their tax reporting periods
conclude.

C. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES

Offsetting Assets and Liabilities require entities to disclose both gross and
net information about instruments and transactions eligible for offset on the
Statements of Assets and Liabilities, and disclose instruments and transactions
subject to master netting or similar agreements. These disclosure requirements
are 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. The transactions subject to offsetting disclosures are derivative
instruments, repurchase agreements and reverse repurchase agreements, and
securities borrowing and securities lending transactions.

This disclosure, if applicable, is included within each Fund's Portfolio of
Investments under the heading "Offsetting Assets and Liabilities." For financial
reporting purposes, the Funds do not offset financial assets and financial
liabilities that are subject to master netting arrangements ("MNAs") or similar
agreements on the Statements of Assets and Liabilities. MNAs provide the right,
in the event of default (including bankruptcy and insolvency), for the
non-defaulting counterparty to liquidate the collateral and calculate the net
exposure to the defaulting party or request additional collateral.

D. SECURITIES LENDING

The Funds may lend securities representing up to 33 1/3% of the value of their
total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, collateral equal to at least 102% (for domestic
securities) or 105% (for international securities) of the market value of the
loaned securities. The collateral amount is valued at the beginning of each
business day and is compared to the market value of the loaned securities from
the prior business day to determine if additional collateral is required. If
additional collateral is required, a request is sent to the borrower. Securities
lending involves the risk that the Fund may lose money because the borrower of
the Fund's loaned securities fails to return the securities in a timely manner
or at all. The Fund could also lose money in the event of (i) a decline in the
value of the collateral provided for the loaned securities, (ii) a decline in
the value of any investments made with cash collateral or (iii) an increase in
the value of the loaned securities if the borrower does not increase the
collateral accordingly and the borrower fails to return the securities. These
events could also trigger adverse tax consequences for the Funds.

Under the Funds' Securities Lending Agency Agreement, the securities lending
agent will generally bear the risk that a borrower may default on its obligation
to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the
Funds' securities lending agent and is responsible for executing the lending of
the portfolio securities to creditworthy borrowers. The Funds, however, will be
responsible for the risks associated with the investment of cash collateral. A
Fund may lose money on its investment of cash collateral, which may affect its
ability to repay the collateral to the borrower without the use of other Fund
assets. Each Fund that engages in securities lending receives compensation (net
of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The dividend and interest earned on the securities loaned is accounted for in
the same manner as other dividend and interest income. At December 31, 2017,
only FDM, FPX, FBT, and FDN had securities in the securities lending program.

In the event of a default by a borrower with respect to any loan, BBH will
exercise any and all remedies provided under the applicable borrower agreement
to make the Funds whole. These remedies include purchasing replacement
securities by applying the collateral held from the defaulting broker against
the purchase cost of the replacement securities. If, despite such efforts by BBH

                               DECEMBER 31, 2017

to exercise these remedies, a Fund sustains losses as a result of a borrower's
default, BBH will indemnify the Fund by purchasing replacement securities at its
own expense, or paying the Fund an amount equal to the market value of the
replacement securities, subject to certain limitations which are set forth in
detail in the Securities Lending Agency Agreement between the Trust on behalf of
the Funds and BBH.

E. REPURCHASE AGREEMENTS

Repurchase agreements involve the purchase of securities subject to the seller's
agreement to repurchase the securities at a mutually agreed upon date and price,
under the terms of a Master Repurchase Agreement ("MRA"). During the term of a
repurchase agreement, the value of the underlying securities held as collateral
on behalf of a Fund, including accrued interest, is required to exceed the value
of the repurchase agreement, including accrued interest. The underlying
securities for all repurchase agreements are held at the Funds' custodian or
designated sub-custodians under tri-party repurchase agreements.

MRAs govern transactions between a Fund and select counterparties. The MRAs
contain provisions for, among other things, initiation, income payments, events
of default, and maintenance of collateral for repurchase agreements.

Repurchase agreements received for lending securities are collateralized by U.S.
Treasury securities. The U.S. Treasury securities are held in a joint custody
account at BBH on behalf of the Funds participating in the securities lending
program. In the event the counterparty defaults on the repurchase agreement, the
U.S. Treasury securities can either be maintained as part of a Fund's portfolio
or sold for cash. A Fund could suffer a loss to the extent that the proceeds
from the sale of the underlying collateral held by the Fund are less than the
repurchase price and the Fund's costs associated with the delay and enforcement
of the MRA.

While the Funds may invest in repurchase agreements, any repurchase agreements
held by the Funds during the year ended December 31, 2017, were received as
collateral for lending securities.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income of each Fund, if any, are declared and paid
quarterly or as the Board of Trustees may determine from time to time.
Distributions of net realized gains earned by each Fund, if any, are distributed
at least annually.

Distributions from 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 Funds and have no impact on net assets or NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some time in the future.

The tax character of distributions paid by each Fund during the year ended
December 31, 2017 was as follows:

G. INCOME TAXES

Each Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, which includes distributing substantially all of its net
investment income and net realized gains to shareholders. Accordingly, no
provision has been made for federal and state income taxes. However, due to the
timing and amount of distributions, each Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of each Fund's taxable income
exceeds the distributions from such taxable income for the calendar year.

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2014, 2015,
2016, and 2017 remain open to federal and state audit. As of December 31, 2017,
management has evaluated the application of these standards to the Funds, and
has determined that no provision for income tax is required in the Funds'
financial statements for uncertain tax positions.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"),
net capital losses arising in taxable years after December 22, 2010, may be
carried forward indefinitely, and their character is retained as short-term
and/or long-term losses. Previously, net capital losses were carried forward for
up to eight years and treated as short-term losses. As a transition rule, the
Act requires that post-enactment net capital losses be used before pre-enactment
net capital losses. At December 31, 2017, the Funds had pre-enactment and
post-enactment net capital losses for federal income tax purposes as shown in
the following table. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to Fund shareholders. The Funds are 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.

In order to present paid-in capital, accumulated net investment income (loss)
and accumulated net realized gain (loss) on investments on the Statements of
Assets and Liabilities that more closely represent their tax character, certain
adjustments have been made to paid-in capital, accumulated net investment income
(loss) and accumulated net realized gain (loss) on investments. These
adjustments are primarily due to the difference between book and tax treatments
of income and gains on various investment securities held by the Funds and
in-kind transactions. The results of operations and net assets were not affected
by these adjustments. For the year ended December 31, 2017, the adjustments for
each Fund were as follows:

I. NEW AND AMENDED FINANCIAL REPORTING RULES AND FORMS

On October 13, 2016, the SEC adopted new rules and forms, and amended existing
rules and forms. The new and amended rules and forms are intended to modernize
the reporting of information provided by funds and to improve the quality and
type of information that funds provide to the SEC and investors. In part, the
new and amended rules and forms amend Regulation S-X and require standardized,
enhanced disclosures about derivatives in a fund's financial statements, as well
as other amendments. The compliance date for the amendments of Regulation S-X
was August 1, 2017, which resulted in no change to the financial statements. The
new form types and other rule amendments will be effective for the First Trust
funds, including the Funds, for reporting periods beginning on and after June 1,
2018. Management is evaluating the new form types and other rule amendments that
are effective on and after June 1, 2018 to determine the impact to the Funds.

 3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS

First Trust, the investment advisor to the Funds, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The

Expenses reimbursed and fees waived by First Trust under the Recovery Agreement
are subject to recovery by First Trust for up to three years from the date the
fee was waived or expense was incurred, but no reimbursement payment will be
made by a Fund if it results in the Fund exceeding an expense ratio equal to the
Expense Cap in place at the time the expenses were reimbursed or fees waived by
First Trust. These amounts are included in "Expenses previously waived or
reimbursed" on the Statements of Operations.

The advisory fee waivers and expense reimbursements for the year ended December

The Trust has multiple service agreements with The Bank of New York Mellon
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
each Fund. As custodian, BNYM is responsible for custody of each Fund's assets.
As fund accountant and administrator, BNYM is responsible for maintaining the
books and records of each Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for each Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund,
or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Trust for acting in such capacities.

                  5. CREATION, REDEMPTION AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Such transactions are generally permitted on an
in-kind basis, with a balancing cash component to equate the transaction to the
daily NAV per Share of each Fund on the transaction date times the number of
Shares in a Creation Unit. Authorized Participants purchasing Creation Units
must pay to BNYM, as transfer agent, a standard creation transaction fee (the
"Creation Transaction Fee"), which is based on the number of different
securities in a Creation Unit of each Fund according to the fee schedule set
forth below:

                     Number of Securities            Creation
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

The Creation Transaction Fee is applicable to each purchase transaction
regardless of the number of Creation Units purchased in the transaction. An
additional variable fee of up to three times the Creation Transaction Fee may be
charged to approximate additional expenses incurred by a Fund with respect to
transactions effected outside of the clearing process (i.e., through a DTC
Participant) or to the extent that cash is used in lieu of securities to
purchase Creation Units. The price for each Creation Unit will equal the daily
NAV per Share of a Fund on the transaction date times the number of Shares in a
Creation Unit plus the fees described above and, if applicable, any transfer
taxes.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
which is based on the number of different securities in a Creation Unit of each
Fund according to the fee schedule set forth below:

                     Number of Securities           Redemption
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

The Redemption Transaction Fee is applicable to each redemption transaction
regardless of the number of Creation Units redeemed in the transaction. An
additional variable fee of up to three times the Redemption Transaction Fee may
be charged to approximate additional expenses incurred by a Fund with respect to
redemptions effected outside of the clearing process or to the extent that
redemptions are for cash. Each Fund reserves the right to effect redemptions in
cash. A shareholder may request cash redemption in lieu of securities; however,
a Fund may, in its discretion, reject any such request.

                              6. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Funds, for amounts expended to finance activities primarily intended to result
in the sale of Creation Units or the provision of investor services. FTP may
also use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before April 30, 2019.

                               7. INDEMNIFICATION

The Trust, on behalf of the Funds, has a variety of indemnification obligations
under contracts with its service providers. The Trust's maximum exposure under
these arrangements is unknown. However, the Trust has not had prior claims or
losses pursuant to these contracts and expects the risk of loss to be remote.

                              8. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Funds
through the date the financial statements were issued, and has determined there
were no subsequent events requiring recognition or disclosure in the financial
statements that have not already been disclosed.


                                                                         Page 67

for the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, the financial highlights for each of the
five years in the period then ended, and the related notes. In our opinion, the
financial statements and financial highlights present fairly, in all material
respects, the financial position of each of the portfolios constituting the
First Trust Exchange-Traded Fund as of December 31, 2017, and the results of
their operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

BASIS FOR OPINION

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

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

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements and financial highlights, whether due
to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements and financial highlights. Our audits
also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 2017, by correspondence with
the custodian and brokers; when replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER EACH FUND'S INVESTMENT
OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST
PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS
AND OTHER INFORMATION ABOUT EACH FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUNDS, PLEASE SEE THE FUNDS' STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND.

The following summarizes some of the risks that should be considered for the
Funds.

Each Fund's shares will change in value, and you could lose money by investing
in a Fund. Shares are subject to market fluctuations caused by such factors as
economic, political, regulatory or market developments, changes in interest
rates and perceived trends in stock prices. Overall stock values could decline
generally or could underperform other investments. Overall stock market values
could decline generally or could underperform other investments.


                                                                         Page 69

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

An investment in a Fund involves risks similar to those of investing in any fund
of equity securities traded on an exchange. Investors buying or selling Fund
shares on the secondary market may incur brokerage commissions. In addition,
investors who sell Fund shares may receive less than the Fund shares' net asset
value. Unlike shares of open-end funds, investors are generally not able to
purchase exchange-traded fund ("ETF") shares directly from a Fund and individual
ETF shares are not redeemable. However, specified large blocks of ETF shares
called creation units can be purchased from, or redeemed to, a Fund.

Each Fund is subject to index tracking risk. You should anticipate that the
value of Fund shares will decline, more or less, in correlation with any decline
in the value of the index that the Fund seeks to track.

Each Fund's return may not match the return of the index it seeks to track for a
number of reasons. While First Trust seeks to have a correlation of 0.95 or
better, before expenses, between a Fund's performance and the performance of its
corresponding index, there can be no assurance that a Fund will be able to
achieve such a correlation. Accordingly, each Fund's performance may correlate
to a lesser extent and may possibly vary substantially from the performance of
its corresponding index.

Each Fund is also exposed to additional market risk due to a policy of investing
principally in the securities included in its corresponding index. As a result
of such policies, securities held by each Fund will generally not be bought or
sold in response to market fluctuations and the securities may be issued by
companies concentrated in a particular industry. As a result, each Fund will
generally not sell a stock because the stock's issuer is in financial trouble,
unless that stock is removed or is anticipated to be removed from the index the
Fund seeks to track.

Each Fund relies on a license from an index provider that permits the Fund to
use its corresponding index and associated trade names and trademarks in
connection with the name and investment strategies of the Fund. Such licenses
may be terminated by the respective index provider and, as a result, each Fund
may lose its ability to use such intellectual property. There is also no
guarantee that the index provider has all rights to license the respective
intellectual property to First Trust, on behalf of the Fund. Accordingly, in the
event the license is terminated or the index provider does not have rights to
license the particular intellectual property, it may have a significant effect
on the operation of the related Fund.

Each Fund is subject to issuer specific changes risk. The value of an individual
security or a particular type of security can be more volatile than the market
as a whole and can perform differently from the value of the market as a whole.

Each Fund will be concentrated in the securities of companies of a given
industry if the Fund's corresponding index is concentrated in such industry. A
concentration makes a Fund more susceptible to any single occurrence affecting
the related industry and may subject a Fund to greater market risk than less
concentrated funds.

Only a party that has entered into a participation agreement an "authorized
participant" may engage in creation or redemption transactions directly with the
Funds. The Funds have a limited number of institutions that act as authorized
participants. To the extent that these institutions exit the business or are
unable to proceed with creation and/or redemption orders with respect to the
Funds and no other authorized participant is able to step forward to create or
redeem, in either of these cases, Fund shares may trade at a discount to a
Fund's net asset value and possibly face delisting.

The Funds have become more susceptible to potential operational risks through
breaches in cyber security as the use of Internet technology has become more
prevalent in the course of business. Cyber security breaches may involve
unauthorized access to the Fund's digital information system or those of the
Fund's third party service providers, such as its administrator, transfer agent,
custodian, or issuers in which the Fund invests. The Funds have established risk
management systems designed to reduce the risks associated with cyber security,
however there is no guarantee that such efforts will succeed.

With the exception of First Trust Capital Strength ETF, First Trust Dow Jones
Select MicroCap Index Fund, First Trust Value Line(R) Dividend Index Fund and
First Trust Value Line(R) 100 Exchange-Traded Fund, each Fund is considered to
be non-diversified. As a result, those Funds are exposed to additional market
risk. A non-diversified fund may invest a relatively high percentage of its
assets in a limited number of issuers. As a result, changes in the market value
of a single portfolio security could cause greater fluctuations in share price
than would occur in a diversified fund. Furthermore, non-diversified funds are
more susceptible to any single political, regulatory or economic occurrence.

The Funds are not actively managed. The Funds may be affected by a general
decline in certain market segments relating to their corresponding index. The
Funds invest in securities included in or representative of their corresponding
index regardless of their investment merit. The Funds generally will not attempt
to take defensive positions in declining markets.

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

The First Trust Dow Jones Select MicroCap Index Fund invests in
micro-capitalization companies. Such companies may be more vulnerable to adverse
general market or economic developments, may be less liquid, and may experience
greater price volatility than larger, more established companies.

The First Trust NYSE Arca Biotechnology Index Fund invests in the securities of
companies in the health care sector. Because companies in the health care sector
are involved in medical services or health care including biotechnology research
and production, drugs and pharmaceuticals and health care facilities and
services, general problems with these companies include extensive competition,
generic drug sales or the loss of patent protection, product liability
litigations and increased government regulations.

The First Trust NYSE Arca Biotechnology Index Fund invests in biotechnology and
pharmaceutical companies that are subject to changing government regulation
which could have a negative effect on the price, profitability of their products
and services. Regulations have been proposed to increase the availability and
affordability of prescription drugs including increased access to generic drugs
and increased rebates paid by drug manufacturers in exchange for Medicaid
coverage of their products. Whether such proposals will be adopted cannot be
predicted. Such companies also face increasing competition from existing generic
drugs, the termination of their patent protection for certain drugs and
technological advances which render their products or services obsolete. The
research and development costs required to bring a drug to market are
substantial and may include a lengthy review by the government, with no
guarantee that the product will ever be brought to market or show a profit. In
addition, the potential for an increased amount of required disclosure of
proprietary scientific information could negatively impact the competitive
position of these companies, many of which may not offer certain drugs or
products for several years, and as a result, may have significant losses of
revenue and earnings.

The First Trust Capital Strength ETF invests in health care companies involved
in medical services or health care, including biotechnology research and
production, drugs and pharmaceuticals and health care facilities and services.
These companies are subject to extensive competition, generic drug sales or the
loss of patent protection, product liability litigation and increased government
regulation. Research and development costs of bringing new drugs to market are
substantial, and there is no guarantee that the product will ever come to
market. Health care facility operators may be affected by the demand for
services, efforts by government or insurers to limit rates, restriction of
government financial assistance and competition from other providers.

The First Trust US Equity Opportunities ETF invests in companies that have
recently conducted an initial public offering. The stocks of such companies are
often subject to extreme price volatility and speculative trading.

The First Trust Dow Jones Select Micro Cap Index Fund and First Trust Value
Line(R) Dividend Index Fund invest in financial companies which are especially
subject to the adverse effects of economic recession, currency exchange rates,
government regulation, decreases in the availability of capital, volatile
interest rates, portfolio concentrations in geographic markets and in commercial
and residential real estate loans, and competition from new entrants in their
fields of business.

The First Trust Capital Strength ETF, First Trust Dow Jones Internet Index Fund,
First Trust US Equity Opportunities ETF and First Trust Value Line(R) 100
Exchange-Traded Fund invest in securities of companies in the information
technology industry. Information technology companies are generally subject to
the risks of rapidly changing technologies; short product life cycles; fierce
competition; and aggressive pricing and reduced profit margins.

The First Trust Dow Jones Internet Index Fund invests in the securities of
Internet companies. Internet companies are subject to rapid changes in
technology, worldwide competition, rapid obsolescence of products and services,
loss of patent protections, cyclical market patterns, evolving industry
standards and frequent new product introductions. The Fund's investment in
Internet companies may also be subject to the risk of owning small
capitalization companies that have recently begun operations.

The First Trust Dow Jones Internet Index Fund, First Trust US Equity
Opportunities ETF, First Trust Value Line(R) 100 Exchange-Traded Fund and First
Trust Dow Jones Internet Index Fund invest in the securities of companies in the
consumer discretionary sector. Because companies in the consumer discretionary
sector provide non-essential goods and services directly to the consumer, the
success of these companies is tied closely to the performance of the overall
domestic and international economy, interest rates, competition and consumer
confidence. Changes in demographics and consumer tastes can also affect the
demand for, and success of, consumer discretionary products.

The First Trust Capital Strength ETF and First Trust Value Line(R) 100
Exchange-Traded Fund invest in the securities of companies in the industrials
sector. General risks of these companies include the general state of the
economy, intense competition, consolidation, domestic and international
politics, excess capacity and consumer demand and spending trends. In addition,
they may also be significantly affected by overall capital spending levels,
economic cycles, technical obsolescence, delays in modernization, labor
relations, government regulations and e-commerce initiatives.


                                                                         Page 71

                         DECEMBER 31, 2017 (UNAUDITED)

The First Trust Capital Strength ETF and First Trust Value Line(R) Dividend
Index Fund invest in the securities of companies in the consumer staples sector.
Consumer staples companies provide products directly to the consumer that are
typically considered non-discretionary items based on consumer purchasing
habits. The success of these companies is affected by a variety of factors, such
as government regulations, which may affect the permissibility of using various
food additives and the production methods of companies that manufacture food
products.

The First Trust Morningstar Dividend Leaders Index Fund and First Trust Value
Line(R) Dividend Index Fund invest in the securities of utilities companies.
Utilities companies are subject to the imposition of rate caps, increased
competition due to deregulation, the difficulty in obtaining an adequate return
on invested capital or in financing large construction projects, the limitations
on operations and increased costs and delays attributable to environmental
considerations, and the capital market's ability to absorb utility debt. In
addition, taxes, government regulation, international politics, price and supply
fluctuations, volatile interest rates and energy conservation may cause
difficulties for utilities. Utilities issuers have been experiencing certain of
these problems to varying degrees.

With the exception of First Trust Capital Strength ETF and First Trust Dow Jones
Select MicroCap Index Fund, the Funds may invest in small capitalization and
mid-capitalization companies. Such companies' securities may be less liquid and
may experience greater price volatility than securities of larger, more
established companies.

Because a Fund's corresponding index may include American Depositary Receipts
("ADRs"), American Depositary Shares ("ADSs") and/or stocks of non-U.S.
companies, the investments of certain Funds, including but not limited to, the
First Trust Value Line(R) 100 Exchange-Traded Fund, involves risks of investing
in non-U.S. securities that are in addition to the risk associated with domestic
securities. Non-U.S. companies, in general, are not subject to the regulatory
requirements of U.S. companies and, as such, there may be less publicly
available information about these companies. Moreover, non-U.S. accounting,
auditing and financial reporting standards generally are different from those
applicable to U.S. companies. In addition, non-U.S. companies are exposed to
additional economic, political, social or diplomatic events. ADRs and ADSs also
involve substantially identical risks to those associated with investments in
non-U.S. securities. In addition, the issuers of certain depositary receipts,
particularly unsponsored or unregistered depositary receipts, are under no
obligation to distribute shareholder communications to the holders of such
receipts, or to pass through to them any voting rights with respect to the
deposited securities.

The First Trust Morningstar Dividend Leaders Index Fund invests in
telecommunications companies which are subject to risks such as a market
characterized by increasing competition and regulation by the Federal
Communications Commission and various state regulatory authorities, the need to
commit substantial capital to meet increasing competition, particularly in
formulating new products and services using new technology, and innovations that
may make various products and services obsolete.

The First Trust Morningstar Dividend Leaders Index Fund invests in the
securities of companies in the energy sector. General problems of issuers in the
energy sector include volatile fluctuations in price and supply of energy fuels
, international politics, terrorist attacks, reduced demand as a result of
increases in energy efficiency and energy conservation, the success of
exploration projects, clean-up and litigation costs relating to oil spills and
environmental damage, and tax and other regulatory policies of various
governments. In addition, oil prices are subject to extreme volatility.

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

                                  REMUNERATION

First Trust Advisors L.P. ("First Trust") is authorised and regulated by the
U.S. Securities and Exchange Commission and is entitled to market shares of the
First Trust Exchange-Traded Funds it manages (the "Funds") in certain member
states in the European Economic Area in accordance with the cooperation
arrangements in Article 42 of the Alternative Investment Fund Managers Directive
(the "Directive"). First Trust is required under the Directive to make
disclosures in respect of remuneration. The following disclosures are made in
line with First Trust's interpretation of currently available regulatory
guidance on remuneration disclosures.

During the year ended December 31, 2017, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $8,575,944.
This figure is comprised of $345,122 paid (or to be paid) in fixed compensation
and $8,230,822 paid (or to be paid) in variable compensation. There were a total
of 14 beneficiaries of the remuneration described above. Those amounts include
$6,004,189 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $2,571,755 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors
L.P. or the Funds (collectively, "Code Staff").

Code Staff included in the aggregated figures disclosed above are rewarded in
line with First Trust's remuneration policy (the "Remuneration Policy") which is
determined and implemented by First Trust's senior management. The Remuneration
Policy reflects First Trust's ethos of good governance and encapsulates the
following principal objectives:

      i.    to provide a clear link between remuneration and performance of
            First Trust and to avoid rewarding for failure;

      ii.   to promote sound and effective risk management consistent with the
            risk profiles of the Funds managed by First Trust; and

      iii.  to remunerate staff in line with the business strategy, objectives,
            values and interests of First Trust and the Funds managed by First
            Trust in a manner that avoids conflicts of interest.

First Trust assesses various risk factors which it is exposed to when
considering and implementing remuneration for Code Staff and considers whether
any potential award to such person(s) would give rise to a conflict of interest.
First Trust does not reward failure, or consider the taking of risk or failure
to take risk in its remuneration of Code Staff.

First Trust assesses performance for the purposes of determining payments in
respect of performance-related remuneration of Code Staff by reference to a
broad range of measures including (i) individual performance (using financial
and non-financial criteria), and (ii) the overall performance of First Trust.
Remuneration is not based upon the performance of the Funds.

The elements of remuneration are balanced between fixed and variable and the
senior management sets fixed salaries at a level sufficient to ensure that
variable remuneration incentivises and rewards strong individual performance but
does not encourage excessive risk taking.

No individual is involved in setting his or her own remuneration.


                                                                         Page 73

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its
investment objective. Each 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 a Fund. See "Risk
Considerations" in the Additional Information section of this report for a
discussion of other risks of investing in the Funds.

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
www.ftportfolios.com or speak with your financial advisor. Investment returns,
net asset value and share price will fluctuate and Fund shares, when sold, may
be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund
performance on each Fund's webpage at www.ftportfolios.com.

                        FIRST TRUST EXCHANGE-TRADED FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                               DECEMBER 31, 2017

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Exchange-Traded Fund which contains detailed information about your investment
for the twelve months ended December 31, 2017, including a market overview and a
performance analysis for the period. We encourage you to read this report
carefully and discuss it with your financial advisor.

This was a very strong year for U.S. markets. The three major indices--the S&P
500(R) Index, the Dow Jones Industrial Average and the Nasdaq posted their best
performance since 2013. And there was more good news for Wall Street:

      o     The S&P 500(R) achieved something it had not previously, finishing
            2017 with 12 months of gains;

      o     The Dow Jones realized a milestone as well, closing above 24,000 for
            the first time ever on November 30; and

      o     The Nasdaq set a record by having 11 months of gains in 2017 (June
            was the only down month, and by just 0.86%).

World markets were also strong in 2017. According to the MSCI AC World Index,
which captures all sources of equity returns in 23 developed and 24 emerging
markets, world stocks rose every month in 2017. The value of public companies on
global stock markets grew by $12.4 trillion during the year.

In 2017, stocks benefitted from increased global demand, growth in corporate
profits (especially technology stocks) and an accommodative Federal Reserve. The
housing market in the United States continues to grow due to a strong job
market, low interest rates and tight inventory. As the year came to a close,
President Trump signed the tax reform package, called the "Tax Cuts and Jobs
Act," which was seen as a promise kept by then-candidate Trump to accomplish
sweeping reform. It is hoped this tax reform will boost economic activity to
greater highs.

At First Trust, we are optimistic about the U.S. economy. We also continue to
believe that you should invest for the long term and be prepared for market
volatility, which can happen at any time. How can you do this? By keeping
current on your portfolio and investing goals by speaking regularly with your
investment professional. It's important to keep in mind that past performance of
the U.S. and global stock markets or investment products can never guarantee
future results. As we've said before, markets go up and they also go down, but
savvy investors are prepared for either through careful attention to their
portfolios and investment goals.

Thank you for giving First Trust the opportunity to be a part of your financial
plan through your investment. We value our relationship with you and will report
on your investment again in six months.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

                        FIRST TRUST EXCHANGE-TRADED FUND
                                 ANNUAL REPORT
                               DECEMBER 31, 2017

ROBERT F. CAREY, CFA
SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST
FIRST TRUST ADVISORS L.P.

Mr. Carey is responsible for the overall management of research and analysis of
the First Trust product line. Mr. Carey has over 25 years of experience as an
Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial
Analyst ("CFA") designation. He is a graduate of the University of Illinois at
Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment
Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a
guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been
quoted by several publications, including The Wall Street Journal, The Wall
Street Reporter, Bloomberg News Service, and Registered Rep.

STATE OF THE ECONOMY/INVESTING

At the midpoint of 2017, House Speaker Paul Ryan stated that he did not think
that the U.S. economy could achieve a 3% gross domestic product ("GDP") growth
rate without passing tax reform legislation. The Tax Cuts and Jobs Act was
signed into law by President Trump on December 22, 2017. One of the main goals
of cutting taxes, both corporate and individual, is to try and boost economic
activity in the U.S. It is true that real GDP growth has topped the 3.0% mark on
an annualized basis the past two quarters (3.1% in the second quarter and 3.2%
in the third quarter), but growth has only averaged 2.2% in the current
recovery, which commenced in the third quarter of 2009, according to data from
the Bureau of Economic Analysis. While it will likely take some time to
determine how effective lower tax rates will be in stimulating economic growth,
particularly the cut from 35% to 21% on the federal tax rate for corporations,
the concept of tax cuts seems to have been well-received by investors since
Trump was elected more than a year ago, in our opinion.

Both small and large companies in the U.S. seem optimistic looking ahead. The
National Federation of Independent Business ("NFIB") reported that its Small
Business Optimism Index hit 107.5 in November, the second-highest reading in its
44-year history, according to its own release. The all-time high was 108.0, set
in September 1983. The NFIB noted that "small business owners are exuberant
about the economy and are ready to lead the U.S. economy in a period of robust
growth." Chief Executive's CEO Confidence Index in Business Conditions 12 Months
Out just registered its second most optimistic year (7.08 out of 10) since the
index commenced in 2003, according to its own release. The highest mark ever
achieved for a calendar year was 7.47 in 2004. The monthly survey of 267 CEOs
revealed that two-thirds of those polled plan to add to their workforce in 2018,
while only 5% forecast a decrease in headcount. CEOs are also expecting to
increase both profitability and revenue in 2018.

ETFGI, an industry research group, reported that total assets invested in
exchange-traded funds ("ETFs") and other exchange-traded products ("ETPs")
listed globally reached an all-time high of $4.83 trillion at the close of 2017,
according to its own release. Total assets invested in ETFs and ETPs listed in
the U.S. reached a record high of $3.42 trillion.

U.S. STOCKS AND BONDS

In 2017, three of the major U.S. stock indices posted double-digit returns. The
S&P 500(R) Index, S&P MidCap 400(R) Index and S&P SmallCap 600(R) Index posted
total returns of 21.83%, 16.24%, and 13.23%, respectively, according to
Bloomberg. Nine of the 11 major S&P 500(R) Index sectors posted positive total
returns. The top-performing sectors were Information Technology, Materials and
Consumer Discretionary, up 38.83%, 23.84% and 22.98%, respectively, on a total
return basis. The two sectors that posted losses were Energy and
Telecommunication Services, down 1.25% and 1.01%, respectively. In general,
cyclical areas of the stock market outperformed non-cyclicals in 2017, an
indication that investors are optimistic about U.S. economic growth moving
forward.

The Federal Reserve ("the Fed") raised the federal funds target rate (upper
bound) three times, from 0.75% to 1.50%, in 2017. It is poised to hike rates
three times in 2018, according to CNBC. The Fed has already raised this rate
five times, dating back to its first hike on December 16, 2015. If the Fed
tightens three times in 2018, the rate will likely hit 2.25%, assuming 25 basis
points per hike. For comparative purposes, the target rate averaged 2.68% for
the 25-year period ended December 29, 2017, according to Bloomberg. The highest
level it reached over that period was 6.50% on May 16, 2000. So while this key
benchmark lending rate is rising, it is still low by historical standards. The
projected bump up in interest rates would not likely derail the bull market in
stocks, but it could put some downward pressure on bond prices by pushing bond
yields higher, in our opinion.

In the U.S. bond market, the top-performing major debt group was high yield
corporate bonds. The Bloomberg Barclays U.S. Corporate High Yield Index posted a
total return of 7.50% in 2017. The worst-performing debt group that we track was
Treasuries, though the group still generated a positive return. The Bloomberg
Barclays U.S. Treasury: Intermediate Index posted a total return of 1.14%. The
yield on the benchmark 10-Year Treasury note (T-note) declined by four basis
points to 2.41% in 2017, according to Bloomberg. The average yield on the
10-year T-note was 2.58% for the 10-year period ended December 29, 2017.

FOREIGN STOCKS AND BONDS

The U.S. dollar declined by 9.87% against a basket of major currencies in 2017,
as measured by the U.S. Dollar Index (DXY). With respect to U.S. investors, a
weaker U.S. dollar can positively impact returns on foreign securities.

The Bloomberg Barclays EM Hard Currency Aggregate Index of emerging markets debt
posted a total return of 9.61% (USD), while the Bloomberg Barclays Global
Aggregate Index of higher quality debt rose 7.39% (USD) in 2017. The MSCI Daily
Total Return Net Emerging Markets Index of stocks posted a total return of
37.28% (USD), while the MSCI Daily Total Return Net World Index (excluding the
U.S.) posted a total return of 24.21% (USD) in 2017.

FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

FIRST TRUST NASDAQ-100 EQUAL WEIGHTED INDEX FUND (QQEW)

The First Trust NASDAQ-100 Equal Weighted Index Fund (the "Fund") seeks
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the NASDAQ-100 Equal
Weighted Index(SM) (the "Index"). The Fund will normally invest at least 90% of
its net assets (including investment borrowings) in common stocks that comprise
the Index. The Index is the equal-weighted version of the NASDAQ-100 Index(R),
which includes 100 of the largest non-financial securities listed on The Nasdaq
Stock Market LLC ("Nasdaq") based on market capitalization. The Index contains
the same securities as the NASDAQ-100 Index(R), but each of the securities is
initially set at a weight of 1.00% of the Index which is rebalanced quarterly.
The Fund's shares are listed for trading on the Nasdaq. The first day of
secondary market trading in shares of the Fund was April 25, 2006.

PERFORMANCE REVIEW

The Fund generated a net asset value ("NAV") return of 26.00% during the
12-month period covered by this report. During the same period, the NASDAQ-100
Index(R) ("benchmark") generated a return of 32.99%. The Information Technology
sector was the highest allocated and top performing sector over the period as it
comprised 40.8% of the Fund and had a 38.9% return, which led to a 15.0%
contribution to the Fund's return. The Consumer Staples sector was the worst
performing sector in the Fund with a 8.3% return and 0.4% contribution. On a
relative basis, the Fund underperformed the benchmark. The Fund underperformed
the benchmark in Consumer Discretionary securities by -13.0% which led to -3.7%
of relative drag. Another -2.6% of underperformance is attributable to the Fund
under allocating the benchmark 17.8% amongst the well performing Information
Technology securities. Underperformance of 0.7% was reversed due to the Fund
outperforming the benchmark in Consumer Staples securities.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

PERFORMANCE REVIEW

The Fund generated a NAV return of 37.86% during the 12-month period covered by
this report. During the same period, the S&P 500 Information Technology Index
("benchmark") generated a return of 38.83%. The Semiconductors & Semiconductor
Equipment and the Software & Services industries were each given an average
weighting of roughly 42.5% in the Fund. The Semiconductors & Semiconductor
Equipment industry had a 44% return in the Fund, leading to a 17.9% contribution
while the Software & Services industry had a 35.5% return in the Fund, leading
to a 15.6% contribution. The worst performing industry was the Technology
Hardware & Equipment industry with a 31% return and 3.8% contribution. On a
relative basis, the Fund underperformed the benchmark. The primary cause of the
underperformance is due to the Fund underperforming in Technology Hardware &
Equipment securities by -9.8%, which resulted in -1.5% of relative drag. The
Software & Services industry created another -1.0% of drag as the Fund
underperformed the benchmark by -2.5%. The Semiconductors & Semiconductor
Equipment industry reversed 2.1% of drag as the Fund over allocated this well
performing industry and outperformed by 5.5%.

its net assets (including investment borrowings) in common stocks that comprise
the Index. The Index contains securities of the NASDAQ-100 Index(R) that are not

non-financial companies listed on the Nasdaq based on market capitalization. The
Index is equally-weighted and is rebalanced four times annually in March, June,

PERFORMANCE REVIEW

The Fund generated a NAV return of 20.41% during the 12-month period covered by
this report. During the same period, the Russell 1000(R) Index ("benchmark")
generated a return of 21.69%. Consumer Discretionary securities were given the
highest allocation in the Fund over the period at 40.1%. This sector had a 17.8%
return and contributed 7.4% to the Fund's return. The top performing sector was
the Information Technology sector with a 40.8% return. This sector was given an
11.3% allocation and had a 4.1% contribution. The worst performing and least
contributing sector was the Consumer Staples sector with an 8.3% return and 0.7%
contribution. On a relative basis, the Fund underperformed the benchmark. The
primary cause of the underperformance is attributable to the Fund
underperforming the benchmark amongst Consumer Discretionary securities by
-5.6%, which created -1.7% of drag. The Fund did not have any allocation to the
Energy sector which resulted in 1.6% of relative outperformance as these
securities were given a 6.0% allocation in the benchmark and had a -1.6% return.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

PERFORMANCE REVIEW

The Fund generated a NAV return of 31.73% during the 12-month period covered by
this report. During the same period, the Russell 2000(R) Index ("benchmark")
generated a return of 14.65%. Information Technology securities comprised the
majority of the Fund at 54.1% over the period and with a return of 42.8% this
led to a 22.0% contribution to the Fund's return. The Semiconductors &
Semiconductor Equipment industry within the Information Technology sector in
particular was given a 38.9% allocation. Although the Energy sector securities
were only given a 2.2% allocation, due to their poor return of -28.7%, they
contributed -1.0% to the Fund's return. Notably, Tesla Inc., part of the
Consumer Discretionary sector, was given a high 8.6% allocation. Tesla Inc. had
a 45.7% return and 5.1% contribution to the Fund's return. Acuity Brands, Inc.,
part of the Industrials sector, was the worst single contributor to the Fund's
return with a -2.4% contribution, stemming from its 7.3% allocation and -23.6%
return. On a relative basis, the Fund outperformed the benchmark. The Fund over
allocated and outperformed the benchmark amongst Information Technology
securities by 37.2% and 25.9%, respectively, which led to 13.9% of relative
outperformance. The Fund's holdings amongst the Industrials sector created -2.7%
of relative drag as the Fund underperformed the benchmark by -15.3%.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST S&P REIT INDEX FUND (FRI)

The First Trust S&P REIT Index Fund (the "Fund") seeks investment results that
correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the S&P United States REIT Index (the
"Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Index. The
Index is a subset of the S&P Developed REIT Index, which measures the
performance of more than 200 REITs or REIT-like structures in 15 developed
markets. The S&P Developed REIT Index is a sub-index of the S&P Global REIT
Index. The S&P Developed REIT Index aims to represent an accurate measure of the
REIT developed equity market, reflecting the risk and return characteristics of
this broad universe on an on-going basis. The Index contains those constituents
of the S&P Developed REIT Index that are domiciled in the United States. The
Index includes the securities of small and mid cap companies. The Fund's shares
are listed for trading on the NYSE Arca. The first day of secondary market
trading in shares of the Fund was May 10, 2007.

PERFORMANCE REVIEW

The Fund generated a NAV return of 3.79% during the 12-month period covered by
this report. During the same period, the Russell 3000(R) Index ("benchmark")
generated a return of 21.13%. Retail Real Estate Investment Trusts ("REITs")
were given the highest allocation in the Fund over the period at 21.5%, but due
to these securities poor return of -4.6%, their contribution to the Fund's
return was -1.3%. Industrial REITs were the Fund's top performing and
contributing REITs with a 23.9% return and 1.4% contribution. On a relative
basis, the Fund underperformed the benchmark. REITs accounted for 2.9% of the
benchmark over the period and contributed 0.1% to the benchmark's return. The
primary cause of the underperformance is attributable to the Fund over
allocating the benchmark among the poor performing Retail REITs by 20.8%
creating -5.7% of relative drag. The only REIT industry in the Fund to create
relative outperformance was the Industrial REITs, which the Fund over allocated
by 6.2%, creating 0.2% of outperformance.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST NATURAL GAS ETF (FCG)

The First Trust Natural Gas ETF (the "Fund"), formerly First Trust ISE-Revere
Natural Gas Index Fund, seeks investment results that correspond generally to
the price and yield (before the Fund's fees and expenses) of an equity index
called the ISE-Revere Natural Gas(TM) Index (the "Index"). The Fund will
normally invest at least 90% of its net assets (including investment borrowings)
in equity securities that comprise the Index. The Index is designed to take
advantage of both event-driven news and long term trends in the natural gas
industry. Equity securities are selected for inclusion in the Index using a
quantitative ranking and screening system that begins with the universe of
equity securities of issuers that are involved in the exploration and production
of natural gas and that satisfy market capitalization, liquidity and weighting
concentration requirements. After application of the screens, the remaining
equity securities are divided into two groups, one for equity securities issued
by master limited partnerships ("MLPs") and one for equity securities issued by
entities that are not MLPs ("non-MLPs"). The Index is allocated 85% to equity
securities issued by non-MLPs, and the remaining 15% consists of equity
securities issued by MLPs. The Index uses a linear-based capitalization-weighted
methodology for each of the MLP and non-MLP group of constituents that initially
ranks the equity securities based on market capitalization and average daily
trading volume, and then adjusts the combined rankings of each equity security
by a factor relating to its market capitalization. The resulting linear weight
distribution prevents a few large component stocks from dominating the Index
while allowing smaller companies to adequately influence Index performance. The
Fund's shares are listed for trading on the NYSE Arca. The first day of
secondary market trading in shares of the Fund was May 11, 2007.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

PERFORMANCE REVIEW

The Fund generated a NAV return of 47.36% during the 12-month period covered by
this report. During the same period, the MSCI Emerging Markets Index
("benchmark") generated a return of 37.28%. Chinese securities were given the
heaviest allocation in the Fund over the period with a 59.9% allocation. These
securities returned 61.3% and contributed 34.5% to the Fund's return. Indian
securities comprised the remainder of the Fund and had a 29.1% return and 12.1%
contribution. On a relative basis, the Fund outperformed the benchmark. The
outperformance can be attributed to the Fund allocating 32.5% more weighting to
the well performing Chinese securities. Relative drag of -2.4% was incurred as a
result of the Fund not being exposed to an appreciated Korean Won relative to
the U.S. Dollar.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST NASDAQ(R) ABA COMMUNITY BANK INDEX FUND (QABA)

The First Trust NASDAQ(R) ABA Community Bank Index Fund (the "Fund") seeks
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the NASDAQ OMX(R) ABA
Community Bank Index(SM) (the "Index"). The Fund will normally invest at least
90% of its net assets (including investment borrowings) in common stocks that
comprise the Index. The Index includes a subset of banks and thrifts or their
holding companies listed on Nasdaq. The Index is jointly owned and was developed
by Nasdaq and the American Bankers Association ("ABA"). For the purposes of the
Index, a "community bank" is considered to be all U.S. banks and thrifts or
their holding companies listed on Nasdaq excluding the 50 largest U.S. banks by
asset size. Also excluded are banks that have an international specialization
and those banks that have a credit-card specialization, as screened by the ABA
based on the most recent data from the Federal Deposit Insurance Company. Banks
with an international specialization are those institutions with assets greater
than $10 billion and more than 25% of total assets in foreign offices. Banks
with a credit-card specialization are those institutions with credit-card loans
plus securitized receivables in excess of 50% of total assets plus securitized
receivables. Securities in the Index must have a market capitalization of at
least $200 million and a three-month average daily trading volume of at least
$500 thousand. The Index is rebalanced quarterly and reconstituted
semi-annually. The Fund's shares are listed for trading on the Nasdaq. The first
day of secondary market trading in shares of the Fund was July 1, 2009.

PERFORMANCE REVIEW

The Fund generated a NAV return of 0.55% during the 12-month period covered by
this report. During the same period, the S&P Composite 1500(R) Financials Index
("benchmark") generated a return of 20.89%. Regional banks from California were
the heaviest allocated banks in the Fund over the period with a 13.5%
allocation. Due to their size, they were also the top contributing banks with a
0.7% contribution, which was limited due to their return being a meager 5.9%.
Regional banks from Colorado were the top performing banks with a 18.2% return,
0.1% contribution, and 0.6% allocation. Regional banks from West Virginia were
the worst performing banks with a -13.6% return and -0.4% contribution. On a
relative basis, the Fund underperformed the benchmark. Relative underperformance
of -19.9% is attributable to the Fund allocating 53.1% more to the banking
industry and underperforming the benchmark amongst banking securities by -18.6%.
Bank of America Corp. in particular caused -2.2% of relative drag on performance
as the Fund did not have any exposure to the 35.7% returning banks, versus the
benchmark which had a 7.2% allocation.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

Total returns for the periods since inception are calculated from the inception
date of each Fund. "Average annual total returns" represent the average annual
change in value of an investment over the periods indicated. "Cumulative total
returns" represent the total change in value of an investment over the periods
indicated. The total returns would have been lower if certain fees had not been
waived and expenses reimbursed by the Advisor.

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period from inception
to the first day of secondary market trading in shares of the Fund, the NAV of
each Fund is used as a proxy for the secondary market trading price to calculate
market returns. NAV and market returns assume that all distributions have been
reinvested in each Fund at NAV and Market Price, respectively.

An index is a statistical composite that tracks a specified financial market or
sector. Unlike each Fund, the indices do not actually hold a portfolio of
securities and therefore do not incur the expenses incurred by each Fund. These
expenses negatively impact the performance of each Fund. Also, market returns do
not include brokerage commissions that may be payable on secondary market
transactions. If brokerage commissions were included, market returns would be
lower. The total returns presented reflect the reinvestment of dividends on
securities in the indices. The returns presented do not reflect the deduction of
taxes that a shareholder would pay on Fund distributions or the redemption or
sale of Fund shares. The investment return and principal value of shares of each
Fund will vary with changes in market conditions. Shares of each Fund may be
worth more or less than their original cost when they are redeemed or sold in
the market. Each Fund's past performance is no guarantee of future performance.

FIRST TRUST EXCHANGE-TRADED FUND

UNDERSTANDING YOUR FUND EXPENSES
DECEMBER 31, 2017 (UNAUDITED)

As a shareholder of First Trust NASDAQ-100 Equal Weighted Index Fund, First
Trust NASDAQ-100-Technology Sector Index Fund, First Trust NASDAQ-100
Ex-Technology Sector Index Fund, First Trust NASDAQ(R) Clean Edge(R) Green
Energy Index Fund, First Trust S&P REIT Index Fund, First Trust Water ETF, First
Trust Natural Gas ETF, First Trust Chindia ETF or First Trust NASDAQ(R)ABA
Community Bank Index Fund (each a "Fund" and collectively, the "Funds"), you
incur two types of costs: (1) transaction costs; and (2) ongoing costs,
including management fees, distribution and/or service fees, if any, and other
Fund expenses. This Example is intended to help you understand your ongoing
costs of investing in the Funds and to compare these costs with the ongoing
costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended December 31, 2017.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this six-month
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on each Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
each Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Funds and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

      distributions or the redemption or sale of Fund shares. Total return is
      calculated for the time period presented and is not annualized for periods
      of less than a year. The total returns would have been lower if certain
      fees had not been waived and expenses reimbursed by the investment
      advisor.

(b)   Portfolio turnover is calculated for the time period presented and is not
      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

(a)   All per share amounts and net asset values have been adjusted to reflect
      the impact of the 1-for-5 reverse share split on May 2, 2016. The net
      asset values reported on December 31, 2015, 2014 and 2013 prior to the
      reverse share split restatement were $4.46, $11.22 and $19.53,
      respectively.

(b)   Total return is calculated assuming an initial investment made at the net
      asset value at the beginning of the period, reinvestment of all
      distributions at net asset value during the period, and redemption at net
      asset value on the last day of the period. The returns presented do not
      reflect the deduction of taxes that a shareholder would pay on Fund
      distributions or the redemption or sale of Fund shares. Total return is
      calculated for the time period presented and is not annualized for periods
      of less than a year. The total returns would have been lower if certain
      fees had not been waived and expenses reimbursed by the investment
      advisor.

(c)   For the years ended December 31, 2017 and 2016, ratios reflect excise tax
      of 0.03% and 0.01%, respectively, which are not included in the expense
      cap.

(d)   Portfolio turnover is calculated for the time period presented and is not
      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

                                1. ORGANIZATION

First Trust Exchange-Traded Fund (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on August 8,
2003, and is registered with the Securities and Exchange Commission ("SEC")
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty exchange-traded funds. This report covers
the nine funds listed below:

      First Trust NASDAQ-100 Equal Weighted Index Fund - (The Nasdaq Stock
         Market LLC ("Nasdaq") ticker "QQEW")
      First Trust NASDAQ-100-Technology Sector Index Fund - (Nasdaq ticker
         "QTEC")
      First Trust NASDAQ-100 Ex-Technology Sector Index Fund - (Nasdaq
         ticker "QQXT")
      First Trust NASDAQ(R) Clean Edge(R) Green Energy Index Fund - (Nasdaq
         ticker "QCLN")
      First Trust S&P REIT Index Fund - (NYSE Arca, Inc. ("NYSE Arca") ticker
         "FRI")
      First Trust Water ETF - (NYSE Arca ticker "FIW")
      First Trust Natural Gas ETF - (NYSE Arca ticker "FCG")
      First Trust Chindia ETF - (NYSE Arca ticker "FNI")
      First Trust NASDAQ(R) ABA Community Bank Index Fund - (Nasdaq ticker
         "QABA")

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Creation Units are generally issued and redeemed in-kind for
securities in which a Fund invests and, in certain circumstances, for cash, and
only to and from broker-dealer and large institutional investors that have
entered into participation agreements. Except when aggregated in Creation Units,
each Fund's shares are not redeemable securities. The investment objective of
each Fund is to seek investment results that correspond generally to the price
and yield (before the Fund's fees and expenses) of the following indices:

following is a summary of significant accounting policies consistently followed
by the Funds in the preparation of the financial statements. The preparation of
the financial statements in accordance with accounting principles generally
accepted in the United States of America ("U.S. GAAP") requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION

Each Fund's NAV is determined daily as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Foreign securities are priced using the data
reflecting the earlier closing of the principal markets for those securities.
Each Fund's NAV is calculated by dividing the value of all assets of each Fund
(including accrued interest and dividends), less all liabilities (including
accrued expenses and dividends declared but unpaid), by the total number of
shares outstanding.

Each Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Funds'


                                                                         Page 61

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Trust's Board of
Trustees, and in accordance with provisions of the 1940 Act. Investments valued
by the Advisor's Pricing Committee, if any, are footnoted as such in the
footnotes to the Portfolio of Investments. Each Fund's investments are valued as
follows:

      Common stocks, real estate investment trusts ("REITs"), master limited
      partnerships ("MLPs") and other equity securities listed on any national
      or foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than
      one securities exchange are valued at the last sale price or official
      closing price, as applicable, at the close of the securities exchange
      representing the principal market for such securities.

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

      Securities traded in an over-the-counter market are fair valued at the
      mean of their most recent bid and asked price, if available, and otherwise
      at their closing bid price.

      Overnight repurchase agreements are valued at amortized cost when it
      represents the best estimate of fair value.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) for which a third-party pricing service is unable to provide a
market price; securities whose trading has been formally suspended; a security
whose market or fair value price is not available from a pre-established pricing
source; a security with respect to which an event has occurred that is likely to
materially affect the value of the security after the market has closed but
before the calculation of a Fund's NAV or make it difficult or impossible to
obtain a reliable market quotation; and a security whose price, as provided by
the third-party pricing service, does not reflect the security's fair value. As
a general principle, the current fair value of a security would appear to be the
amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

In addition, differences between the prices used to calculate a Fund's NAV and
the prices used by such Fund's corresponding index could result in a difference
between a Fund's performance and the performance of its underlying index.

The Funds are subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investment.

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of December 31, 2017, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

Withholding taxes and tax reclaims on foreign dividends have been provided for
in accordance with each Fund's understanding of the applicable country's tax
rules and rates.

Distributions received from a Fund's investments in MLPs generally are comprised
of return of capital and investment income. A Fund records estimated return of
capital and investment income based on historical information available from
each MLP. These estimates may subsequently be revised based on information
received from the MLPs after their tax reporting periods are concluded.

Distributions received from a Fund's investments in REITs may be comprised of
return of capital, capital gains and income. The actual character of the amounts
received during the year is not known until after the REITs' fiscal year end. A
Fund records the character of distributions received from the REITs during the
year based on estimates available. The characterization of distributions
received by a Fund may be subsequently revised based on information received
from the REITs after their tax reporting periods conclude.

C. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES

Offsetting Assets and Liabilities requires entities to disclose both gross and
net information about instruments and transactions eligible for offset on the
Statements of Assets and Liabilities, and disclose instruments and transactions
subject to master netting or similar agreements. These disclosure requirements
are 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. The transactions subject to offsetting disclosures are derivative
instruments, repurchase agreements and reverse repurchase agreements, and
securities borrowing and securities lending transactions.

This disclosure, if applicable, is included within each Fund's Portfolio of
Investments under the heading "Offsetting Assets and Liabilities". For financial
reporting purposes, the Funds do not offset financial assets and financial
liabilities that are subject to master netting arrangements ("MNAs") or similar
agreements on the Statements of Assets and Liabilities. MNAs provide the right,
in the event of default (including bankruptcy and insolvency), for the
non-defaulting counterparty to liquidate the collateral and calculate the net
exposure to the defaulting party or request additional collateral.

D. SECURITIES LENDING

The Funds may lend securities representing up to 33 1/3% of the value of their
total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, collateral equal to at least 102% (for domestic
securities) or 105% (for international securities) of the market value of the
loaned securities. The collateral amount is valued at the beginning of each
business day and is compared to the market value of the loaned securities from
the prior business day to determine if additional collateral is required. If
additional collateral is required, a request is sent to the borrower. Securities
lending involves the risk that the Fund may lose money because the borrower of
the Fund's loaned securities fails to return the securities in a timely manner
or at all. The Fund could also lose money in the event of (i) a decline in the
value of the collateral provided for the loaned securities, (ii) a decline in
the value of any investments made with cash collateral or (iii) an increase in
the value of the loaned securities if the borrower does not increase the
collateral accordingly and the borrower fails to return the securities. These
events could also trigger adverse tax consequences for the Funds.

Under the Funds' Securities Lending Agency Agreement, the securities lending
agent will generally bear the risk that a borrower may default on its obligation
to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the
Funds' securities lending agent and is responsible for executing the lending of
the portfolio securities to creditworthy borrowers. The Funds, however, will be
responsible for the risks associated with the investment of cash collateral. A
Fund may lose money on its investment of cash collateral, which may affect its
ability to repay the collateral to the borrower without the use of other Fund
assets. Each Fund that engages in securities lending receives compensation (net
of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The dividend and interest earned on the securities loaned is accounted for in
the same manner as other dividend and interest income. At December 31, 2017,
QQEW, QQXT, QCLN, FIW, FCG, FNI, and QABA have securities in the securities
lending program. During the fiscal year ended December 31, 2017, QQEW, QTEC,
QQXT, QCLN, FIW, FCG, FNI, and QABA participated in the securities lending
program.


                                                                         Page 63

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

In the event of a default by a borrower with respect to any loan, BBH will
exercise any and all remedies provided under the applicable borrower agreement
to make the Funds whole. These remedies include purchasing replacement
securities by applying the collateral held from the defaulting broker against
the purchase cost of the replacement securities. If, despite such efforts by BBH
to exercise these remedies, a Fund sustains losses as a result of a borrower's
default, BBH will indemnify the Fund by purchasing replacement securities at its
own expense, or paying the Fund an amount equal to the market value of the
replacement securities, subject to certain limitations which are set forth in
detail in the Securities Lending Agency Agreement between the Trust on behalf of
the Funds and BBH.

E. REPURCHASE AGREEMENTS

Repurchase agreements involve the purchase of securities subject to the seller's
agreement to repurchase the securities at a mutually agreed upon date and price,
under the terms of a Master Repurchase Agreement ("MRA"). During the term of a
repurchase agreement, the value of the underlying securities held as collateral
on behalf of a Fund, including accrued interest, is required to exceed the value
of the repurchase agreement, including accrued interest. The underlying
securities for all repurchase agreements are held at the Funds' custodian or
designated sub-custodians under tri-party repurchase agreements.

MRAs govern transactions between a Fund and select counterparties. The MRAs
contain provisions for, among other things, initiation, income payments, events
of default, and maintenance of collateral for repurchase agreements.

Repurchase agreements received for lending securities are collateralized by U.S.
Treasury securities. The U.S. Treasury securities are held in a joint custody
account at BBH on behalf of the Funds participating in the securities lending
program. In the event the counterparty defaults on the repurchase agreement, the
U.S. Treasury securities can either be maintained as part of a Fund's portfolio
or sold for cash. A Fund could suffer a loss to the extent that the proceeds
from the sale of the underlying collateral held by the Fund are less than the
repurchase price and the Fund's costs associated with the delay and enforcement
of the MRA.

While the Funds may invest in repurchase agreements, any repurchase agreements
held by the Funds during the year ended December 31, 2017, were received as
collateral for lending securities.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income of each Fund, if any, are declared and paid
quarterly, or as the Board of Trustees may determine from time to time.
Distributions of net realized gains earned by each Fund, if any, are distributed
at least annually.

Distributions from 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 Funds and have no impact on net assets or NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some time in the future.

The tax character of distributions paid by each Fund during the year ended
December 31, 2017 was as follows:



                                                                       Distributions        Distributions        Distributions

G. INCOME TAXES

Each Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, which includes distributing substantially all of its net
investment income and net realized gains to shareholders. Accordingly, no
provision has been made for federal and state income taxes. However, due to the
timing and amount of distributions, each Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of each Fund's taxable income
exceeds the distributions from such taxable income for the calendar year.

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2014, 2015,
2016, and 2017 remain open to federal and state audit. As of December 31, 2017,
management has evaluated the application of these standards to the Funds, and
has determined that no provision for income tax is required in the Funds'
financial statements for uncertain tax positions.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"),
net capital losses arising in taxable years after December 22, 2010, may be
carried forward indefinitely, and their character is retained as short-term
and/or long-term losses. Previously, net capital losses were carried forward for
up to eight years and treated as short-term losses. As a transition rule, the
Act requires that post-enactment net capital losses be used before pre-enactment
net capital losses. At December 31, 2017, the Funds had net capital losses for
federal income tax purposes as shown in the following table. To the extent that
these loss carryforwards are used to offset future capital gains, it is probable
that the capital gains so offset will not be distributed to Fund shareholders.
The Funds are 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.


                                                                         Page 65

In order to present paid-in capital, accumulated net investment income (loss)
and accumulated net realized gain (loss) on investments on the Statements of
Assets and Liabilities that more closely represent their tax character, certain
adjustments have been made to paid-in capital, accumulated net investment income
(loss) and accumulated net realized gain (loss) on investments. These
adjustments are primarily due to the difference between book and tax treatments
of income and gains on various investment securities held by the Funds and
in-kind transactions. The results of operations and net assets were not affected
by these adjustments. For the year ended December 31, 2017, the adjustments for
each Fund were as follows:

I. NEW AND AMENDED FINANCIAL REPORTING RULES AND FORMS

On October 13, 2016, the SEC adopted new rules and forms, and amended existing
rules and forms. The new and amended rules and forms are intended to modernize
the reporting of information provided by funds and to improve the quality and
type of information that funds provide to the SEC and investors. In part, the
new and amended rules and forms amend Regulation S-X and require standardized,
enhanced disclosures about derivatives in a fund's financial statements, as well
as other amendments. The compliance date for the amendments of Regulation S-X
was August 1, 2017, which resulted in no change to the financial statements. The
new form types and other rule amendments will be effective for the First Trust
funds, including the Funds, for reporting periods beginning on and after June 1,
2018. Management is evaluating the new form types and other rule amendments that
are effective on and after June 1, 2018 to determine the impact to the Funds.

During the year ended December 31, 2017, First Trust recovered fees that were

First Trust S&P REIT Index Fund and First Trust Water ETF do not have any
remaining fees previously waived or expenses reimbursed that are subject to
recovery.

The Trust has multiple service agreements with The Bank of New York Mellon
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
each Fund. As custodian, BNYM is responsible for custody of each Fund's assets.
As fund accountant and administrator, BNYM is responsible for maintaining the
books and records of each Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for each Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund,
or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Trust for acting in such capacities.

                             4. REVERSE SHARE SPLIT

On April 22, 2016, the Trust's Board of Trustees approved a one-for-five reverse
share split, whereby every five outstanding shares of FCG as of the close of
business on April 29, 2016 automatically converted to one share as of the
opening of business on May 2, 2016. For the fiscal year ended December 31, 2016,
the share transactions on the Statements of Changes in Net Assets reflect the
actual transactions, including the impact of the reverse share split. As a
result of the reverse share split, fractional shares totaling 1,635 shares were
redeemed and paid out to shareholders. The reverse share split had no impact on
the overall value of a shareholder's investment in FCG.

                      5. PURCHASES AND SALES OF SECURITIES

                  6. CREATION, REDEMPTION AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Such transactions are generally permitted on an
in-kind basis, with a balancing cash component to equate the transaction to the
daily NAV per Share of each Fund on the transaction date times the number of
Shares in a Creation Unit. Authorized Participants purchasing Creation Units
must pay to BNYM, as transfer agent, a standard creation transaction fee (the
"Creation Transaction Fee"), which is based on the number of different
securities in a Creation Unit of each Fund according to the fee schedule set
forth below:

                     Number of Securities            Creation
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

The Creation Transaction Fee is applicable to each purchase transaction
regardless of the number of Creation Units purchased in the transaction. An
additional variable fee of up to three times the Creation Transaction Fee may be
charged to approximate additional expenses incurred by a Fund with respect to
transactions effected outside of the clearing process (i.e., through a DTC
Participant) or to the extent that cash is used in lieu of securities to
purchase Creation Units. The price for each Creation Unit will equal the daily
NAV per Share of a Fund on the transaction date times the number of Shares in a
Creation Unit plus the fees described above and, if applicable, any transfer
taxes.


                                                                         Page 69

                               DECEMBER 31, 2017

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
which is based on the number of different securities in a Creation Unit of each
Fund according to the fee schedule set forth below:

                     Number of Securities           Redemption
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

The Redemption Transaction Fee is applicable to each redemption transaction
regardless of the number of Creation Units redeemed in the transaction. An
additional variable fee of up to three times the Redemption Transaction Fee may
be charged to approximate additional expenses incurred by a Fund with respect to
redemptions effected outside of the clearing process or to the extent that
redemptions are for cash. Each Fund reserves the right to effect redemptions in
cash. A shareholder may request cash redemption in lieu of securities; however,
a Fund may, in its discretion, reject any such request.

                              7. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Funds, for amounts expended to finance activities primarily intended to result
in the sale of Creation Units or the provision of investor services. FTP may
also use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before April 30, 2019.

                               8. INDEMNIFICATION

The Trust, on behalf of the Funds, has a variety of indemnification obligations
under contracts with its service providers. The Trust's maximum exposure under
these arrangements is unknown. However, the Trust has not had prior claims or
losses pursuant to these contracts and expects the risk of loss to be remote.

                              9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Funds
through the date the financial statements were issued, and has determined that
there were no subsequent events requiring recognition or disclosure in the
financial statements that have not already been disclosed.

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

TO THE SHAREHOLDERS AND THE BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust NASDAQ-100 Equal Weighted Index Fund, First Trust NASDAQ-100-Technology
Sector Index Fund, First Trust NASDAQ-100 Ex-Technology Sector Index Fund, First
Trust NASDAQ(R) Clean Edge(R) Green Energy Index Fund, First Trust S&P REIT
Index Fund, First Trust Water ETF, First Trust Natural Gas ETF, First Trust
Chindia ETF, and First Trust NASDAQ(R) ABA Community Bank Index Fund (the
"Funds"), each a series of the First Trust Exchange-Traded Fund (the "Trust"),
including the portfolios of investments, as of December 31, 2017, the related
statements of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, the financial
highlights for each of the five years in the period then ended, and the related
notes. In our opinion, the financial statements and financial highlights present
fairly, in all material respects, the financial position of each of the
portfolios constituting the First Trust Exchange-Traded Fund as of December 31,
2017, and the results of their operations for the year then ended, the changes
in their net assets for each of the two years in the period then ended, and the
financial highlights for each of the five years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

BASIS FOR OPINION

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

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

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements and financial highlights, whether due
to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements and financial highlights. Our audits
also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 2017, by correspondence with
the custodian and brokers; when replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER EACH FUND'S INVESTMENT
OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST
PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS
AND OTHER INFORMATION ABOUT EACH FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUNDS, PLEASE SEE THE FUNDS' STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND.

The following summarizes some of the risks that should be considered for the
Funds.

Each Fund's shares will change in value, and you could lose money by investing
in a Fund. Shares are subject to market fluctuations caused by such factors as
economic, political, regulatory or market developments, changes in interest
rates and perceived trends in stock prices. Overall stock values could decline
generally or could underperform other investments. Overall stock market values
could decline generally or could underperform other investments.

An investment in a Fund involves risks similar to those of investing in any fund
of equity securities traded on an exchange. Investors buying or selling Fund
shares on the secondary market may incur brokerage commissions. In addition,
investors who sell Fund shares may receive less than the Fund shares' net asset
value. Unlike shares of open-end funds, investors are generally not able to
purchase exchange-traded fund ("ETF") shares directly from a Fund and individual
ETF shares are not redeemable. However, specified large blocks of ETF shares
called creation units can be purchased from, or redeemed to, a Fund.

Each Fund is subject to index tracking risk. You should anticipate that the
value of Fund shares will decline, more or less, in correlation with any decline
in the value of the index that the Fund seeks to track.

Each Fund's return may not match the return of the index it seeks to track for a
number of reasons. While First Trust seeks to have a correlation of 0.95 or
better, before expenses, between a Fund's performance and the performance of its
corresponding index, there can be no assurance that a Fund will be able to
achieve such a correlation. Accordingly, each Fund's performance may correlate
to a lesser extent and may possibly vary substantially from the performance of
its corresponding index.

Each Fund is also exposed to additional market risk due to a policy of investing
principally in the securities included in its corresponding index. As a result
of such policies, securities held by each Fund will generally not be bought or
sold in response to market fluctuations and the securities may be issued by
companies concentrated in a particular industry. As a result, each Fund will
generally not sell a stock because the stock's issuer is in financial trouble,
unless that stock is removed or is anticipated to be removed from the index the
Fund seeks to track.

Each Fund relies on a license from an index provider that permits the Fund to
use its corresponding index and associated trade names and trademarks in
connection with the name and investment strategies of the Fund. Such licenses
may be terminated by the respective index provider and, as a result, each Fund
may lose its ability to use such intellectual property. There is also no
guarantee that the index provider has all rights to license the respective
intellectual property to First Trust, on behalf of the Fund. Accordingly, in the
event the license is terminated or the index provider does not have rights to
license the particular intellectual property, it may have a significant effect
on the operation of the related Fund.

The Funds have become more susceptible to potential operational risks through
breaches in cyber security as the use of Internet technology has become more
prevalent in the course of business. Cyber security breaches may involve
unauthorized access to a Fund's digital information systems or those of a Fund's
third party service providers, such as its administrator, transfer agent,
custodian, or issuers in which a Fund invests. The Funds have established risk
management systems designed to reduce the risks associated with cyber security,
however, there is no guarantee that such efforts will succeed.

Each Fund is subject to issuer specific changes risk. The value of an individual
security or a particular type of security can be more volatile than the market
as a whole and can perform differently from the value of the market as a whole.

Each Fund will be concentrated in the securities of companies of a given
industry if the Fund's corresponding index is concentrated in such industry. A
concentration makes a Fund more susceptible to any single occurrence affecting
the related industry and may subject a Fund to greater market risk than less
concentrated funds.


                                                                         Page 73

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

Only a party that has entered into a participation agreement (an "authorized
participant") may engage in creation or redemption transactions directly with
the Funds. The Funds have a limited number of institutions that act as
authorized participants. To the extent that these institutions exit the business
or are unable to proceed with creation and/or redemption orders with respect to
the Funds and no other authorized participant is able to step forward to create
or redeem, in either of these cases, Fund shares may trade at a discount to a
Fund's net asset value and possibly face delisting.

First Trust NASDAQ(R) Clean Edge(R) Green Energy Index Fund and First Trust
Chindia ETF are non-diversified. As a result, those Funds are exposed to
additional market risk. A non-diversified fund may invest a relatively high
percentage of its assets in a limited number of issuers. As a result, changes in
the market value of a single portfolio security could cause greater fluctuations
in share price than would occur in a diversified fund. Furthermore,
non-diversified funds are more susceptible to any single political, regulatory
or economic occurrence.

The Funds are not actively managed. The Funds may be affected by a general
decline in certain market segments relating to their corresponding index. The
Funds invest in securities included in or representative of their corresponding
index regardless of their investment merit. The Funds generally will not attempt
to take defensive positions in declining markets.

The First Trust NASDAQ-100 Equal Weighted Index Fund and the First Trust
NASDAQ-100-Technology Sector Index Fund invest in stocks of companies in the
technology sector. You should be aware that an investment in a portfolio which
invests in a particular sector involves additional risks, including limited
diversification. The companies engaged in the technology sector are subject to
fierce competition and high research and development costs, and their products
and services may be subject to rapid obsolescence.

The First Trust Chindia ETF, First Trust S&P REIT Index Fund and First Trust
NASDAQ(R) ABA Community Bank Index Fund invest in securities of companies in the
financials and/or real estate sectors. Banks, thrifts and their holding
companies are especially subject to the adverse effects of economic recession;
volatile interest rates; portfolio concentrations in geographic markets and in
commercial and residential real estate loans; and competition from new entrants
in their fields of business. Although recently enacted legislation repealed most
of the barriers which separated the banking, insurance and securities
industries, these industries are still extensively regulated at both the federal
and state level and may be adversely affected by increased regulations.

The First Trust Chindia ETF, the First Trust NASDAQ-100 Equal Weighted Index
Fund, the First Trust NASDAQ-100-Technology Sector Index Fund and the First
Trust NASDAQ(R) Clean Edge(R) Green Energy Index Fund invest in securities of
companies in the information technology industry. Information technology
companies are generally subject to the risks of rapidly changing technologies;
short product life cycles; fierce competition; and aggressive pricing and
reduced profit margins and have experienced extreme price and volume
fluctuations that are often unrelated to their operating performance.

The First Trust Chindia ETF, First Trust NASDAQ-100 Ex-Technology Sector Index
Fund and First Trust NASDAQ-100 Equal Weighted Index Fund invest in the
securities of companies in the consumer discretionary sector. Because companies
in the consumer discretionary sector manufacture products and provide
discretionary services directly to the consumer, the success of these companies
is tied closely to the performance of the overall domestic and international
economy, interest rates, competition and consumer confidence. Success depends
heavily on disposable household income and consumer spending. Changes in
demographics and consumer tastes can also affect the demand for, and success of,
consumer discretionary products in the marketplace.

The First Trust Natural Gas ETF invests in the securities of companies in the
energy sector. General problems of issuers in the energy sector include volatile
fluctuations in price and supply of energy fuels, international politics,
terrorist attacks, reduced demand as a result of increases in energy efficiency
and energy conservation, the success of exploration projects, clean-up and
litigation costs relating to oil spills and environmental damage, and tax and
other regulatory policies of various governments. In addition, oil prices are
subject to extreme volatility.

The First Trust Water ETF and the First Trust NASDAQ(R) Clean Edge(R) Green
Energy Index Fund invest in the securities of companies in the industrials
sector. General risks of these companies include the general state of the
economy, intense competition, consolidation, domestic and international
politics, excess capacity and consumer demand and spending trends. In addition,
they may also be significantly affected by overall capital spending levels,
economic cycles, technical obsolescence, delays in modernization, labor
relations, government regulations and e-commerce initiatives.

The First Trust S&P REIT Index Fund invests in companies in the real estate
industry, including real estate investment trusts ("REITs") and is subject to
the risks associated with investing in real estate (any of which could cause the
value of a REIT's stock price to decline), which may include, but are not
limited to, possible declines in the value of real estate, adverse general and
local economic conditions, possible lack of availability of mortgage funds,
overbuilding in a REIT's market, changes in interest rates and environmental
problems. Furthermore, increases in interest rates typically lower the present
value of a REIT's future earnings stream, and may make financing property
purchases and improvements more costly. Retail REITs own and operate properties

                         DECEMBER 31, 2017 (UNAUDITED)

available for lease to retail companies. In addition to the risks related to
REITs generally, retail REITs are especially sensitive to local and national
economic cycles and are subject to decreases in demand for retail rental
properties, defaults by tenants and declines in rental market rates and economic
down cycles. Retail REITs are also negatively impacted by retail company
bankruptcies and restructurings, including store closings, and changes in
consumer discretionary spending.

The First Trust NASDAQ-100 Ex-Technology Sector Index Fund invests in the
securities of companies in the health care sector. Because companies in the
health care sector are involved in medical services or health care including
biotechnology research and production, drugs and pharmaceuticals and health care
facilities and services, general problems of these companies include extensive
competition, generic drug sales or the loss of patent protection, product
liability litigation and increased government regulations.

The First Trust Water ETF invests in the securities of utilities companies.
Utilities companies are subject to the imposition of rate caps, increased
competition due to deregulation, the difficulty in obtaining an adequate return
on invested capital or in financing large construction projects, the limitations
on operations and increased costs and delays attributable to environmental
considerations, and the capital market's ability to absorb utility debt. In
addition, taxes, government regulation, international politics, price and supply
fluctuations, volatile interest rates and energy conservation may cause
difficulties for utilities. Utilities issuers have been experiencing certain of
these problems to varying degrees.

The Funds may invest in small capitalization and mid-capitalization companies.
Such companies' securities may be less liquid and may experience greater price
volatility than securities of larger, more established companies.

Because a Fund's corresponding index may include American Depositary Receipts
("ADRs"), American Depositary Shares ("ADSs") and/or stocks of non-U.S.
companies, the investments of certain Funds, including but not limited to, the
First Trust Chindia ETF, the First Trust Natural Gas ETF and the First Trust
Water ETF involve risks of investing in non-U.S. securities that are in addition
to the risk associated with domestic securities. Non-U.S. companies, in general,
are not subject to the regulatory requirements of U.S. companies and, as such,
there may be less publicly available information about these companies.
Moreover, non-U.S. accounting, auditing and financial reporting standards
generally are different from those applicable to U.S. companies. In addition,
non-U.S. companies are exposed to additional economic, political, social or
diplomatic events. ADRs and ADSs also involve substantially identical risks to
those associated with investments in non-U.S. securities. In addition, the
issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder
communications to the holders of such receipts, or to pass through to them any
voting rights with respect to the deposited securities.

The First Trust NASDAQ(R) Clean Edge(R) Green Energy Index Fund invests in
renewable and alternative energy companies. You should be aware that share
prices of renewable and alternative energy companies have been significantly
more volatile than shares of companies operating in other more established
industries and the securities included in the First Trust NASDAQ(R) Clean
Edge(R) Green Energy Index Fund may be subject to sharp price declines. This
industry is relatively nascent and under-researched in comparison to more
established and mature sectors, and should therefore be regarded as having
greater investment risk.

The First Trust Water ETF invests in companies in the potable water and
wastewater industries. You should be aware that adverse developments in these
industries may significantly affect the value of the shares of the First Trust
ISE Water Index Fund. Companies involved in the potable water and wastewater
industries are subject to environmental considerations, taxes, government
regulation, price and supply fluctuations, competition and conservation.

The First Trust Natural Gas ETF invests in companies in the natural gas
industry. You should be aware that one of the natural gas industry's primary
risks is the competitive risk associated with the prices of alternative fuels,
such as coal and oil. Additionally, the natural gas industry is sensitive to
increased interest rates because of the industry's capital intensive nature.
Furthermore, there are additional risks and hazards that are inherent in the
natural gas industry that may cause the price of natural gas to widely
fluctuate.

The First Trust Chindia ETF invests in the securities of companies domiciled in
China and India. You should be aware that investments in such companies are
subject to additional risks, including investment restrictions which may affect
liquidity and risks associated with possible adverse economic, political and
social developments in those countries.

The First Trust NASDAQ(R) ABA Community Bank Index Fund is concentrated in the
securities of NASDAQ(R) listed community banks which were significantly impacted
by the downturn in the United States and world economies that began with the
decline in the subprime mortgage lending market in the United States, and have
brought about legislative and regulatory changes, changes in short-term and
long-term interest rates, inflation and changes in government monetary and
fiscal policies, all of which have had a significant impact on the banking
business. Community banks may also be affected by anticipated government fiscal
policy initiatives and the market reaction to those initiatives.


                                                                         Page 75

                         DECEMBER 31, 2017 (UNAUDITED)

A community bank's financial performance may be highly dependent upon the
business environment in certain geographic regions of the United States and may
be adversely impacted by any downturn or unfavorable economic or employment
developments in its local market and the United States as a whole. This impacts
the ability of borrowers to pay interest on and repay principal of outstanding
loans and the value of collateral securing those loans. Also, the securities of
community banks are often subject to low trading volume and low analyst
coverage.

First Trust NASDAQ-100-Technology Sector Index Fund and First Trust NASDAQ(R)
Clean Edge(R) Green Energy Index Fund invest in semiconductor companies.
Semiconductor companies are primarily involved in the design, distribution,
manufacture and sale of semiconductors. Semiconductor companies are
significantly affected by rapid obsolescence, intense competition and global
demand. The Fund is also subject to the risk that the securities of such issuers
will underperform the market as a whole due to legislative or regulatory
changes. The prices of the securities of semiconductor companies may fluctuate
widely in response to such events.

First Trust Natural Gas ETF invests in MLPs. An investment in MLP units involves
risks which differ from an investment in common stock of a corporation. Holders
of MLP units have limited control and voting rights on matters affecting the
partnership. In addition, there are certain tax risks associated with an
investment in MLP units and conflicts of interest may exist between common unit
holders and the general partner, including those arising from incentive
distribution payments. In addition, there is the risk that an MLP could be,
contrary to its intention, taxed as a corporation, resulting in decreased
returns from such MLP.

                                  REMUNERATION

First Trust Advisors L.P. ("First Trust") is authorised and regulated by the
U.S. Securities and Exchange Commission and is entitled to market shares of the
First Trust Exchange-Traded Funds it manages (the "Funds") in certain member
states in the European Economic Area in accordance with the cooperation
arrangements in Article 42 of the Alternative Investment Fund Managers Directive
(the "Directive"). First Trust is required under the Directive to make
disclosures in respect of remuneration. The following disclosures are made in
line with First Trust's interpretation of currently available regulatory
guidance on remuneration disclosures.

During the year ended December 31, 2017, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $8,575,944.
This figure is comprised of $345,122 paid (or to be paid) in fixed compensation
and $8,230,822 paid (or to be paid) in variable compensation. There were a total
of 14 beneficiaries of the remuneration described above. Those amounts include
$6,004,189 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $2,571,755 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors
L.P. or the Funds (collectively, "Code Staff").

Code Staff included in the aggregated figures disclosed above are rewarded in
line with First Trust's remuneration policy (the "Remuneration Policy") which is
determined and implemented by First Trust's senior management. The Remuneration
Policy reflects First Trust's ethos of good governance and encapsulates the
following principal objectives:

      i.    to provide a clear link between remuneration and performance of
            First Trust and to avoid rewarding for failure;

      ii.   to promote sound and effective risk management consistent with the
            risk profiles of the Funds managed by First Trust; and

      iii.  to remunerate staff in line with the business strategy, objectives,
            values and interests of First Trust and the Funds managed by First
            Trust in a manner that avoids conflicts of interest.

First Trust assesses various risk factors which it is exposed to when
considering and implementing remuneration for Code Staff and considers whether
any potential award to such person(s) would give rise to a conflict of interest.
First Trust does not reward failure, or consider the taking of risk or failure
to take risk in its remuneration of Code Staff.

First Trust assesses performance for the purposes of determining payments in
respect of performance-related remuneration of Code Staff by reference to a
broad range of measures including (i) individual performance (using financial
and non-financial criteria), and (ii) the overall performance of First Trust.
Remuneration is not based upon the performance of the Funds.

The elements of remuneration are balanced between fixed and variable and the
senior management sets fixed salaries at a level sufficient to ensure that
variable remuneration incentivises and rewards strong individual performance but
does not encourage excessive risk taking.

No individual is involved in setting his or her own remuneration.

                  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 its 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
any series of First Trust Exchange-Traded Fund (the "Trust") described in this
report (each such series is referred to as a "Fund" and collectively, as the
"Funds") 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 its 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.

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its
investment objective. Each 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 a Fund. See "Risk
Considerations" in the Additional Information Section of this report for a
discussion of other risks of investing in the Funds.

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
www.ftportfolios.com or speak with your financial advisor. Investment returns,
net asset value and share price will fluctuate and Fund shares, when sold, may
be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund
performance on each Fund's webpage at www.ftportfolios.com.

                            HOW TO READ THIS REPORT

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

By reading the market overview by Robert F. Carey, Chief Market Strategist of
the Advisor, you may obtain an understanding of how the market environment
affected the performance of each Fund. The statistical information that follows
may help you understand each Fund's performance compared to that of relevant

SHAREHOLDER LETTER

                        FIRST TRUST EXCHANGE-TRADED FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                               DECEMBER 31, 2017

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Exchange-Traded Fund which contains detailed information about your investment
for the twelve months ended December 31, 2017, including a market overview and a
performance analysis for the period. We encourage you to read this report
carefully and discuss it with your financial advisor.

This was a very strong year for U.S. markets. The three major indices--the S&P
500(R) Index, the Dow Jones Industrial Average and the Nasdaq posted their best
performance since 2013. And there was more good news for Wall Street:

      o     The S&P 500(R) achieved something it had not previously finishing
            2017 with 12 months of gains;

      o     The Dow Jones realized a milestone as well closing above 24,000 for
            the first time ever on November 30; and

      o     The Nasdaq set a record by having 11 months of gains in 2017 (June
            was the only down month, and by just 0.86%).

World markets were also strong in 2017. According to the MSCI AC World Index,
which captures all sources of equity returns in 23 developed and 24 emerging
markets, world stocks rose every month in 2017. The value of public companies on
global stock markets grew by $12.4 trillion during the year.

In 2017, stocks benefitted from increased global demand, growth in corporate
profits (especially technology stocks) and an accommodative Federal Reserve. The
housing market in the United States continues to grow due to a strong job
market, low interest rates and tight inventory. As the year came to a close,
President Trump signed the tax reform package, called the "Tax Cuts and Jobs
Act," which was seen as a promise kept by then-candidate Trump to accomplish
sweeping reform. It is hoped this tax reform will boost economic activity to
greater highs.

At First Trust, we are optimistic about the U.S. economy. We also continue to
believe that you should invest for the long term and be prepared for market
volatility, which can happen at any time. How can you do this? By keeping
current on your portfolio and investing goals by speaking regularly with your
investment professional. It's important to keep in mind that past performance of
the U.S. and global stock markets or investment products can never guarantee
future results. As we've said before, markets go up and they also go down, but
savvy investors are prepared for either through careful attention to their
portfolios and investment goals.

Thank you for giving First Trust the opportunity to be a part of your financial
plan through your investment. We value our relationship with you and will report
on your investment again in six months.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

                        FIRST TRUST EXCHANGE-TRADED FUND
                                 ANNUAL REPORT
                               DECEMBER 31, 2017

ROBERT F. CAREY, CFA
SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST
FIRST TRUST ADVISORS L.P.

Mr. Carey is responsible for the overall management of research and analysis of
the First Trust product line. Mr. Carey has over 25 years of experience as an
Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial
Analyst ("CFA") designation. He is a graduate of the University of Illinois at
Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment
Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a
guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been
quoted by several publications, including The Wall Street Journal, The Wall
Street Reporter, Bloomberg News Service, and Registered Rep.

STATE OF THE ECONOMY/INVESTING

At the midpoint of 2017, House Speaker Paul Ryan stated that he did not think
that the U.S. economy could achieve a 3% gross domestic product ("GDP") growth
rate without passing tax reform legislation. The Tax Cuts and Jobs Act was
signed into law by President Trump on December 22, 2017. One of the main goals
of cutting taxes, both corporate and individual, is to try and boost economic
activity in the U.S. It is true that real GDP growth has topped the 3.0% mark on
an annualized basis the past two quarters (3.1% in the second quarter and 3.2%
in the third quarter), but growth has only averaged 2.2% in the current
recovery, which commenced in the third quarter of 2009, according to data from
the Bureau of Economic Analysis. While it will likely take some time to
determine how effective lower tax rates will be in stimulating economic growth,
particularly the cut from 35% to 21% on the federal tax rate for corporations,
the concept of tax cuts seems to have been well-received by investors since
Trump was elected more than a year ago, in our opinion.

Both small and large companies in the U.S. seem optimistic looking ahead. The
National Federation of Independent Business ("NFIB") reported that its Small
Business Optimism Index hit 107.5 in November, the second-highest reading in its
44-year history, according to its own release. The all-time high was 108.0, set
in September 1983. The NFIB noted that "small business owners are exuberant
about the economy and are ready to lead the U.S. economy in a period of robust
growth." Chief Executive's CEO Confidence Index in Business Conditions 12 Months
Out just registered its second most optimistic year (7.08 out of 10) since the
index commenced in 2003, according to its own release. The highest mark ever
achieved for a calendar year was 7.47 in 2004. The monthly survey of 267 CEOs
revealed that two-thirds of those polled plan to add to their workforce in 2018,
while only 5% forecast a decrease in headcount. CEOs are also expecting to
increase both profitability and revenue in 2018.

ETFGI, an industry research group, reported that total assets invested in
exchange-traded funds ("ETFs") and other exchange-traded products ("ETPs")
listed globally reached an all-time high of $4.83 trillion at the close of 2017,
according to its own release. Total assets invested in ETFs and ETPs listed in
the U.S. reached a record high of $3.42 trillion.

U.S. STOCKS AND BONDS

In 2017, three of the major U.S. stock indices posted double-digit returns. The
S&P 500(R) Index, S&P MidCap 400(R) Index and S&P SmallCap 600(R) Index posted
total returns of 21.83%, 16.24%, and 13.23%, respectively, according to
Bloomberg. Nine of the 11 major S&P 500(R) Index sectors posted positive total
returns. The top-performing sectors were Information Technology, Materials and
Consumer Discretionary, up 38.83%, 23.84% and 22.98%, respectively, on a total
return basis. The two sectors that posted losses were Energy and
Telecommunication Services, down 1.25% and 1.01%, respectively. In general,
cyclical areas of the stock market outperformed non-cyclicals in 2017, an
indication that investors are optimistic about U.S. economic growth moving
forward.

The Federal Reserve ("the Fed") raised the federal funds target rate (upper
bound) three times, from 0.75% to 1.50%, in 2017. It is poised to hike rates
three times in 2018, according to CNBC. The Fed has already raised this rate
five times, dating back to its first hike on December 16, 2015. If the Fed
tightens three times in 2018, the rate will likely hit 2.25%, assuming 25 basis
points per hike. For comparative purposes, the target rate averaged 2.68% for
the 25-year period ended December 29, 2017, according to Bloomberg. The highest
level it reached over that period was 6.50% on May 16, 2000. So while this key
benchmark lending rate is rising, it is still low by historical standards. The
projected bump up in interest rates would not likely derail the bull market in
stocks, but it could put some downward pressure on bond prices by pushing bond
yields higher, in our opinion.

In the U.S. bond market, the top-performing major debt group was high yield
corporate bonds. The Bloomberg Barclays U.S. Corporate High Yield Index posted a
total return of 7.50% in 2017. The worst-performing debt group that we track was
Treasuries, though the group still generated a positive return. The Bloomberg
Barclays U.S. Treasury: Intermediate Index posted a total return of 1.14%. The
yield on the benchmark 10-Year Treasury note (T-note) declined by four basis
points to 2.41% in 2017, according to Bloomberg. The average yield on the
10-year T-note was 2.58% for the 10-year period ended December 29, 2017.

FOREIGN STOCKS AND BONDS

The U.S. dollar declined by 9.87% against a basket of major currencies in 2017,
as measured by the U.S. Dollar Index (DXY). With respect to U.S. investors, a
weaker U.S. dollar can positively impact returns on foreign securities.

The Bloomberg Barclays EM Hard Currency Aggregate Index of emerging markets debt
posted a total return of 9.61% (USD), while the Bloomberg Barclays Global
Aggregate Index of higher quality debt rose 7.39% (USD) in 2017. The MSCI Daily
Total Return Net Emerging Markets Index of stocks posted a total return of
37.28% (USD), while the MSCI Daily Total Return Net World Index (excluding the
U.S.) posted a total return of 24.21% (USD) in 2017.

FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

FIRST TRUST TOTAL US MARKET ALPHADEX(R) ETF (TUSA)

The First Trust Total US Market AlphaDEX(R) ETF (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the NASDAQ AlphaDEX(R) Total US Market
Index (the "Index"). The Fund will normally invest at least 90% of its assets in
common stocks that comprise the Index. The Index is designed to quantitatively
identify and select stocks across market capitalizations (including large-cap,
mid-cap and small-cap companies) that exhibit growth and value factors and
appear to have the greatest potential for capital appreciation. The Index is a
modified equal-dollar weighted index. The Index is reconstituted and balanced on
a quarterly basis. The Fund's shares are listed for trading on The Nasdaq Stock
Market LLC. The first day of secondary market trading in shares of the Fund was
December 7, 2006.

* On January 9, 2015, the Fund's underlying index changed from the Value Line(R)
Equity Allocation Index to the NASDAQ AlphaDEX(R) Total US Market Index.
Therefore, the Fund's performance and total returns shown for the periods prior
to January 9, 2015, are not necessarily indicative of the performance the Fund,
based on its current index, would have generated. Since the Fund's new
underlying index had an inception date of September 8, 2014, it was not in
existence for all of the periods disclosed.

(See Notes to Fund Performance Overview on page 10.)

PERFORMANCE REVIEW

The Fund generated a net asset value ("NAV") return of 19.44% during the
12-month period covered by this report. During the same period, the Russell
3000(R) Index ("benchmark") generated a return of 21.13%. The Consumer
Discretionary sector was given the highest allocation in the Fund at 18.4% over
the period. The largest contributing sector to the Fund's return was the
Information Technology sector with a 5.5% contribution, stemming from its 17.5%
allocation and 32.1% return. The Telecommunication Services sector was the only
negatively contributing sector over the period with a -0.2% contribution,
stemming from its 1.4% allocation and -11.7% return. On a relative basis, the
Fund underperformed the benchmark. The primary cause of the underperformance is
attributable to the Fund under allocating and underperforming the benchmark
amongst Information Technology securities, leading to -1.5% of drag. The Fund
outperformed the benchmark amongst Energy securities by 8.8% leading to 1.2% of
relative outperformance in this sector.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST DORSEY WRIGHT PEOPLE'S PORTFOLIO ETF (DWPP)

From the beginning of the period covered by this report until August 18, 2017,
the First Trust Dorsey Wright People's Portfolio ETF (the "Fund"), formerly
First Trust CBOE(R) S&P 500(R) VIX(R) Tail Hedge Fund, sought investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the CBOE(R) VIX(R) Tail Hedge Index.
Effective August 18, 2017, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an index called the Nasdaq Dorsey Wright People's
Portfolio Index (the "Index"). The Fund will normally invest at least 80% of its
total assets (including investment borrowings) in common stocks or U.S. Treasury
Bills ("T-Bills") that comprise the Index. The Index is designed to provide
exposure to either the U.S. equity market or T-Bills, based upon daily relative
strength readings resulting from a wholly-quantitative process. The Index always
holds exactly one of three possible positions: all the component securities of
the Nasdaq US 500 Large Cap Index, all the component securities in the Nasdaq US
500 Large Cap Equal Weight Index or all the component securities of the Nasdaq
US T-Bill Index. Each of the Nasdaq US 500 Large Cap Index and the Nasdaq US 500
Large Cap Equal Weight Index contains the same constituent securities - the 500
securities with the highest float market capitalization comprising the NASDAQ US
Benchmark Index - but weights them differently. The Nasdaq US 500 Large Cap
Index weights the securities according to their market capitalization and the
Nasdaq US 500 Large Cap Equal Index weights them equally. The Nasdaq US T-Bill
Index is designed to act as a US dollar-denominated cash position through the
use of nine T-Bills ranging from 30 to 91 days in duration. A T-Bill is a
short-term debt obligation backed by the U.S. government with a maturity of less
than one year, sold in denominations of $1,000 up to a maximum purchase of $5
million. From the beginning of the period covered by this report until August
18, 2017, the shares of the Fund traded on the NYSE Arca. Effective August 18,
2017, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC
under the ticker symbol "DWPP." The first day of secondary market trading in
shares of the Fund was August 30, 2012.

* On August 18, 2017, the Fund's underlying index changed from the CBOE(R)
VIX(R) Tail Hedge Index to the Nasdaq Dorsey Wright People's Portfolio Index
(the "Index"). Therefore, the Fund's performance and total returns shown for the
periods prior to August 18, 2017, are not necessarily indicative of the
performance the Fund, based on its current index, would have generated. Since
the Index had an inception date of July 24, 2017, it was not in existence for
all of the periods disclosed.

(See Notes to Fund Performance Overview on page 10.)

PERFORMANCE REVIEW

The Fund generated a NAV return of 21.71% during the 12-month period covered by
this report. During the same period, the S&P 500(R) Index ("benchmark")
generated a return of 21.83%. The Information Technology sector was the heaviest
allocated sector in the Fund over the period with a 19.8% weighting. With a
38.2% return this sector was the top performing sector and led to a contribution
of 6.9% to the Fund's return. Apple, Inc. was the highest allocated single
security with a 2.4% weighting. The Telecommunication Services sector was the
worst performing sector in the Fund with a -6.6% return, which led to a
contribution of -0.2%. On a relative basis, the Fund underperformed the
benchmark. The primary cause of the underperformance can be attributed to the
Fund overweighting and underperforming the benchmark amongst Utilities
securities by 0.8% and -1.3%, respectively, leading to -0.4% of relative drag.
The Fund's holdings amongst Industrial securities reversed -0.5% of
underperformance as the Fund outperformed the benchmark by 3.9% in this sector.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period January 1, 2013 through
December 31, 2017. Shareholders may pay more than NAV when they buy Fund shares
and receive less than NAV when they sell those shares because shares are bought
and sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST DOW 30 EQUAL WEIGHT ETF (EDOW)

The First Trust Dow 30 Equal Weight ETF (the "Fund") seeks investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity Index called the Dow Jones Industrial Average Equal
Weight Index (the "Index"). The Fund will normally invest at least 90% of its
net assets (including investment borrowings) in common stocks that comprise the
Index. The Index consists of an equally weighted portfolio of the 30 securities
that comprise the Dow Jones Industrial Average(TM) (the "DJIA"). The 30
securities comprising the DJIA are domestic, blue-chip companies covering all
industries. While inclusion in the DJIA is not governed by quantitative rules, a
stock is typically only added if the company has an excellent reputation,
demonstrates sustained growth and is of interest to a large number of investors.
The Index is rebalanced quarterly. The first day of secondary market trading in
shares of the Fund was August 9, 2017.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF DECEMBER 31, 2017

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 9, 2017 (commencement
of trading) through December 31, 2017. Shareholders may pay more than NAV when
they buy Fund shares and receive less than NAV when they sell those shares
because shares are bought and sold at current market price. Data presented
represents past performance and cannot be used to predict future results.

--------------------------------------------------------------------------------
NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

Total returns for the periods since inception are calculated from the inception
date of each Fund. "Average annual total returns" represent the average annual
change in value of an investment over the periods indicated. "Cumulative total
returns" represent the total change in value of an investment over the periods
indicated. The total returns would have been lower if certain fees had not been
waived and expenses reimbursed by the Advisor.

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period from inception
to the first day of secondary market trading in shares of the Fund, the NAV of
each Fund is used as a proxy for the secondary market trading price to calculate
market returns. NAV and market returns assume that all distributions have been
reinvested in each Fund at NAV and Market Price, respectively.

An index is a statistical composite that tracks a specified financial market or
sector. Unlike each Fund, the indices do not actually hold a portfolio of
securities and therefore do not incur the expenses incurred by each Fund. These
expenses negatively impact the performance of each Fund. Also, market returns do
not include brokerage commissions that may be payable on secondary market
transactions. If brokerage commissions were included, market returns would be
lower. The total returns presented reflect the reinvestment of dividends on
securities in the indices. The returns presented do not reflect the deduction of
taxes that a shareholder would pay on Fund distributions or the redemption or
sale of Fund shares. The investment return and principal value of shares of each
Fund will vary with changes in market conditions. Shares of each Fund may be
worth more or less than their original cost when they are redeemed or sold in
the market. Each Fund's past performance is no guarantee of future performance.

FIRST TRUST EXCHANGE-TRADED FUND

UNDERSTANDING YOUR FUND EXPENSES
DECEMBER 31, 2017 (UNAUDITED)

As a shareholder of First Trust Total US Market AlphaDEX(R) ETF, First Trust
Dorsey Wright People's Portfolio ETF or First Trust Dow 30 Equal Weight ETF
(each a "Fund" and collectively, the "Funds"), you incur two types of costs: (1)
transaction costs; and (2) ongoing costs, including management fees,
distribution and/or service fees, if any, and other Fund expenses. This Example
is intended to help you understand your ongoing costs of investing in the Funds
and to compare these costs with the ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period (or since inception) and held through the six-month (or shorter) period
ended December 31, 2017.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this six-month
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on each Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
each Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Funds and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)   Total return is calculated assuming an initial investment made at the net
      asset value at the beginning of the period, reinvestment of all
      distributions at net asset value during the period, and redemption at net
      asset value on the last day of the period. The returns presented do not
      reflect the deduction of taxes that a shareholder would pay on Fund
      distributions or the redemption or sale of Fund shares. Total return is
      calculated for the time period presented and is not annualized for periods
      of less than a year. The total returns for First Trust Total US Market
      AlphaDEX(R) ETF would have been lower if certain fees had not been waived
      and expenses reimbursed by the investment advisor.

(b)   Portfolio turnover is calculated for the time period presented and is not
      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

(c)   The variation in the portfolio turnover rate is due to the change in the
      Fund's underlying index effective August 18, 2017, which resulted in a
      complete rebalance of the Fund's portfolio.

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

                                1. ORGANIZATION

First Trust Exchange-Traded Fund (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on August 8,
2003, and is registered with the Securities and Exchange Commission ("SEC")
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty exchange-traded funds. This report covers
the three funds listed below:

      First Trust Total US Market AlphaDEX(R) ETF - (The Nasdaq Stock Market LLC
         ("Nasdaq") ticker "TUSA")
      First Trust Dorsey Wright People's Portfolio ETF - (Nasdaq ticker
         "DWPP")(1)
      First Trust Dow 30 Equal Weight ETF - (NYSE Arca, Inc. ("NYSE Arca")
         ticker "EDOW")(2)

(1)   Effective on August 18, 2017, First Trust CBOE(R) S&P 500(R) VIX(R) Tail
      Hedge Fund (NYSE Arca ticker "VIXH") changed its name and ticker symbol to
      First Trust Dorsey Wright People's Portfolio ETF (Nasdaq ticker "DWPP").

(2)   Commenced investment operations on August 8, 2017.

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Creation Units are generally issued and redeemed in-kind for
securities in which a Fund invests and, in certain circumstances, for cash, and
only to and from broker-dealers and large institutional investors that have
entered into participation agreements. Except when aggregated in Creation Units,
each Fund's shares are not redeemable securities. The investment objective of
each Fund is to seek investment results that correspond generally to the price
and yield (before the Fund's fees and expenses) of the following indices:



FUND                                                            INDEX
                                                             
First Trust Total US Market AlphaDEX(R) ETF                     NASDAQ AlphaDEX(R) Total US Market Index
First Trust Dorsey Wright People's Portfolio ETF                Nasdaq Dorsey Wright People's Portfolio Index(3)
First Trust Dow 30 Equal Weight ETF                             Dow Jones Industrial Average(R) Equal Weight Index


(3)   Effective on August 18, 2017, First Trust Dorsey Wright People's Portfolio
      ETF's underlying index was changed from the CBOE(R) VIX(R) Tail Hedge
      Index to the Nasdaq Dorsey Wright People's Portfolio Index.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Funds are each considered an investment company and follow accounting and
reporting guidance under Financial Accounting Standards Board Accounting
Standards Codification Topic 946, "Financial Services-Investment Companies." The
following is a summary of significant accounting policies consistently followed
by the Funds in the preparation of the financial statements. The preparation of
the financial statements in accordance with accounting principles generally
accepted in the United States of America ("U.S. GAAP") requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION

Each Fund's NAV is determined daily as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Each Fund's NAV is calculated by dividing the
value of all assets of each Fund (including accrued interest and dividends),
less all liabilities (including accrued expenses and dividends declared but
unpaid), by the total number of shares outstanding.

Each Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Funds'
investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Trust's Board of
Trustees, and in accordance with provisions of the 1940 Act. Investments valued
by the Advisor's Pricing Committee, if any, are footnoted as such in the
footnotes to the Portfolio of Investments. Each Fund's investments are valued as
follows:

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than


                                                                         Page 41

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
--------------------------------------------------------------------------------

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

      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.

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

      Securities traded in an over-the-counter market are fair valued at the
      mean of their most recent bid and asked price, if available, and otherwise
      at their closing bid price.

      Overnight repurchase agreements are valued at amortized cost when it
      represents the best estimate of fair value.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) for which a third-party pricing service is unable to provide a
market price; securities whose trading has been formally suspended; a security
whose market or fair value price is not available from a pre-established pricing
source; a security with respect to which an event has occurred that is likely to
materially affect the value of the security after the market has closed but
before the calculation of a Fund's NAV or make it difficult or impossible to
obtain a reliable market quotation; and a security whose price, as provided by
the third-party pricing service, does not reflect the security's fair value. As
a general principle, the current fair value of a security would appear to be the
amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

In addition, differences between the prices used to calculate a Fund's NAV and
the prices used by such Fund's corresponding index could result in a difference
between a Fund's performance and the performance of its underlying index.

The Funds are subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investment.

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of December 31, 2017, is
included with each Fund's Portfolio of Investments.

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

B. CALL OPTIONS

Prior to August 18, 2017, VIXH was subject to equity price risk in the normal
course of pursuing its investment objective and could purchase out-of-the-money
call options on the Chicago Board Options Exchange Market Volatility Index(R)
(the "VIX Index") to hedge against changes in the value of equities. Also, VIXH
could sell call options on the VIX Index in order to close out existing
positions. The purchase of call options involved the risk of loss of all or a
part of the cash paid for the call options (the premium). The market risk
associated with purchasing options on the VIX Index was limited to the premium
paid. When VIXH purchased a call option, the premium paid represented the cost
of the call option. Options were marked-to-market daily and their value was
affected by changes in the market value of the stocks included in the stock
index. If VIXH elected to exercise a call option on the VIX Index, settlement
did not occur by the delivery of the securities comprising the VIX Index. VIXH,
as holder of the stock index option, received an amount of cash if the closing
level of the stock index upon which the option was based was greater than, in
the case of a call, or less than in the case of a put, the exercise price of the
option. This amount of cash was equal to the difference between the closing
price of the stock index and the exercise price of the option expressed in
dollars times a specified multiple. If VIXH elected to allow a call option to
expire, then the equity price risk for purchased options was limited to the
premium initially paid. During the period ended August 18, 2017, there were no
open, expired or closed option contracts. As a result of the index change on
August 18, 2017, DWPP no longer engages in options activities.

C. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

Withholding taxes and tax reclaims on foreign dividends have been provided for
in accordance with each Fund's understanding of the applicable country's tax
rules and rates.

Distributions received from a Fund's investments in real estate investment
trusts ("REITs") may be comprised of return of capital, capital gains and
income. The actual character of the amounts received during the year is not
known until after the REITs' fiscal year end. A Fund records the character of
distributions received from the REITs during the year based on estimates
available. The characterization of distributions received by a Fund may be
subsequently revised based on information received from the REITs after their
tax reporting periods conclude.

D. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES

Offsetting Assets and Liabilities requires entities to disclose both gross and
net information about instruments and transactions eligible for offset on the
Statements of Assets and Liabilities, and disclose instruments and transactions
subject to master netting or similar agreements. These disclosure requirements
are 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. The transactions subject to offsetting disclosures are derivative
instruments, repurchase agreements and reverse repurchase agreements, and
securities borrowing and securities lending transactions.

This disclosure, if applicable, is included within each Fund's Portfolio of
Investments under the heading "Offsetting Assets and Liabilities". For financial
reporting purposes, the Funds do not offset financial assets and financial
liabilities that are subject to master netting arrangements ("MNAs") or similar
agreements on the Statements of Assets and Liabilities. MNAs provide the right,
in the event of default (including bankruptcy and insolvency), for the
non-defaulting counterparty to liquidate the collateral and calculate the net
exposure to the defaulting party or request additional collateral.

E. SECURITIES LENDING

The Funds may lend securities representing up to 33 1/3% of the value of their
total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, collateral equal to at least 102% (for domestic
securities) or 105% (for international securities) of the market value of the
loaned securities. The collateral amount is valued at the beginning of each
business day and is compared to the market value of the loaned securities from
the prior business day to determine if additional collateral is required. If
additional collateral is required, a request is sent to the borrower. Securities
lending involves the risk that the Fund may lose money because the borrower of
the Fund's loaned securities fails to return the securities in a timely manner
or at all. The Fund could also lose money in the event of (i) a decline in the
value of the collateral provided for the loaned securities, (ii) a decline in
the value of any investments made with cash collateral or (iii) an increase in
the value of the loaned securities if the borrower does not increase the
collateral accordingly and the borrower fails to return the securities. These
events could also trigger adverse tax consequences for the Funds.


                                                                         Page 43

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

Under the Funds' Securities Lending Agency Agreement, the securities lending
agent will generally bear the risk that a borrower may default on its obligation
to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the
Funds' securities lending agent and is responsible for executing the lending of
the portfolio securities to creditworthy borrowers. The Funds, however, will be
responsible for the risks associated with the investment of cash collateral. A
Fund may lose money on its investment of cash collateral, which may affect its
ability to repay the collateral to the borrower without the use of other Fund
assets. Each Fund that engages in securities lending receives compensation (net
of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The dividend and interest earned on the securities loaned is accounted for in
the same manner as other dividend and interest income. At December 31, 2017,
only TUSA had securities in the securities lending program.

In the event of a default by a borrower with respect to any loan, BBH will
exercise any and all remedies provided under the applicable borrower agreement
to make the Funds whole. These remedies include purchasing replacement
securities by applying the collateral held from the defaulting broker against
the purchase cost of the replacement securities. If, despite such efforts by BBH
to exercise these remedies, a Fund sustains losses as a result of a borrower's
default, BBH will indemnify the Fund by purchasing replacement securities at its
own expense, or paying the Fund an amount equal to the market value of the
replacement securities, subject to certain limitations which are set forth in
detail in the Securities Lending Agency Agreement between the Trust on behalf of
the Funds and BBH.

F. REPURCHASE AGREEMENTS

Repurchase agreements involve the purchase of securities subject to the seller's
agreement to repurchase the securities at a mutually agreed upon date and price,
under the terms of a Master Repurchase Agreement ("MRA"). During the term of a
repurchase agreement, the value of the underlying securities held as collateral
on behalf of a Fund, including accrued interest, is required to exceed the value
of the repurchase agreement, including accrued interest. The underlying
securities for all repurchase agreements are held at the Funds' custodian or
designated sub-custodians under tri-party repurchase agreements.

MRAs govern transactions between a Fund and select counterparties. The MRAs
contain provisions for, among other things, initiation, income payments, events
of default, and maintenance of collateral for repurchase agreements.

Repurchase agreements received for lending securities are collateralized by U.S.
Treasury securities. The U.S. Treasury securities are held in a joint custody
account at BBH on behalf of the Funds participating in the securities lending
program. In the event the counterparty defaults on the repurchase agreement, the
U.S. Treasury securities can either be maintained as part of a Fund's portfolio
or sold for cash. A Fund could suffer a loss to the extent that the proceeds
from the sale of the underlying collateral held by the Fund are less than the
repurchase price and the Fund's costs associated with the delay and enforcement
of the MRA.

While the Funds may invest in repurchase agreements, any repurchase agreements
held by the Funds during the period ended December 31, 2017, were received as
collateral for lending securities.

G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income of each Fund, if any, are declared and paid
quarterly, or as the Board of Trustees may determine from time to time.
Distributions of net realized gains earned by each Fund, if any, are distributed
at least annually.

Distributions from 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 Funds and have no impact on net assets or NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some time in the future.

The tax character of distributions paid by each Fund during the period ended
December 31, 2017 was as follows:




                                                                                            Distributions        Distributions

H. INCOME TAXES

Each Fund intends to qualify or continue to qualify as a regulated investment
company by complying with the requirements under Subchapter M of the Internal
Revenue Code of 1986, as amended, which includes distributing substantially all
of its net investment income and net realized gains to shareholders.
Accordingly, no provision has been made for federal and state income taxes.
However, due to the timing and amount of distributions, each Fund may be subject
to an excise tax of 4% of the amount by which approximately 98% of each Fund's
taxable income exceeds the distributions from such taxable income for the
calendar year.

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. For TUSA and DWPP, the taxable
years ending 2014, 2015, 2016, and 2017 remain open to federal and state audit.
For EDOW, the taxable year ending 2017 remains open for federal and state audit.
As of December 31, 2017, management has evaluated the application of these
standards to the Funds, and has determined that no provision for income tax is
required in the Funds' financial statements for uncertain tax positions.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"),
net capital losses arising in taxable years after December 22, 2010, may be
carried forward indefinitely, and their character is retained as short-term
and/or long-term losses. Previously, net capital losses were carried forward for
up to eight years and treated as short-term losses. As a transition rule, the
Act requires that post-enactment net capital losses be used before pre-enactment
net capital losses. At December 31, 2017, for federal income tax purposes, each
Fund has capital loss carryforwards available as shown in the following table.
To the extent that these loss carryforwards are used to offset future capital
gains, it is probable that the capital gains so offset will not be distributed
to Fund shareholders. The Funds are 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.



                                                                        Capital Loss            Post-                Total

                        FIRST TRUST EXCHANGE-TRADED FUND
                               DECEMBER 31, 2017

At the taxable year ended December 31, 2017, the following Fund's capital loss
carryforwards expired in the following amount:



                                                                        Capital Loss

                                                                          Expired
                                                                     ------------------
                                                                    
First Trust Total US Market AlphaDEX(R) ETF                            $    2,421,122


In order to present paid-in capital, accumulated net investment income (loss)
and accumulated net realized gain (loss) on investments on the Statements of
Assets and Liabilities that more closely represent their tax character, certain
adjustments have been made to paid-in capital, accumulated net investment income
(loss) and accumulated net realized gain (loss) on investments. These
adjustments are primarily due to the difference between book and tax treatments
of income and gains on various investment securities held by the Funds and
in-kind transactions. The results of operations and net assets were not affected
by these adjustments. For the period ended December 31, 2017, the adjustments
for each Fund were as follows:



                                                                                             Accumulated

type of information that funds provide to the SEC and investors. In part, the
new and amended rules and forms amend Regulation S-X and require standardized,
enhanced disclosures about derivatives in a fund's financial statements, as well
as other amendments. The compliance date for the amendments of Regulation S-X
was August 1, 2017, which resulted in no change to the financial statements. The
new form types and other rule amendments will be effective for the First Trust
funds, including the Funds, for reporting periods beginning on and after June 1,
2018. Management is evaluating the new form types and other rule amendments that
are effective on and after June 1, 2018 to determine the impact to the Funds.

                               DECEMBER 31, 2017

For the First Trust Total US Market AlphaDEX(R) ETF, First Trust is paid an
annual management fee of 0.50% of the Fund's average daily net assets. For such
Fund, the Trust and the Advisor have entered into an Expense Reimbursement, Fee
Waiver and Recovery Agreement ("Recovery Agreement") in which First Trust has
agreed to waive fees and/or reimburse Fund expenses to the extent that the
operating expenses of the Fund (excluding interest expense, brokerage
commissions and other trading expenses, acquired fund fees and expenses, taxes
and extraordinary expenses) exceed 0.70% of average daily net assets per year
(the "Expense Cap"). The Expense Cap will be in effect until at least April 30,
2019.

Expenses reimbursed and fees waived by First Trust under the Recovery Agreement
are subject to recovery by First Trust for up to three years from the date the
fee was waived or expense was incurred, but no reimbursement payment will be
made by the Fund if it results in the Fund exceeding an expense ratio equal to
the Expense Cap in place at the time the expenses were reimbursed or fees were
waived by First Trust. This amount would be included in "Expenses previously
waived or reimbursed" on the Statements of Operations.

retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund,
or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee

                                                                  ---------------   ---------------
                                                                              
First Trust Total US Market AlphaDEX(R) ETF                       $     7,668,111   $     3,148,643
First Trust Dorsey Wright People's Portfolio ETF                       30,052,689         6,755,886
First Trust Dow 30 Equal Weight ETF                                     4,085,163         2,112,294


                  5. CREATION, REDEMPTION AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Such transactions are generally permitted on an
in-kind basis, with a balancing cash component to equate the transaction to the
daily NAV per Share of each Fund on the transaction date times the number of
Shares in a Creation Unit. Authorized Participants purchasing First Trust Total
US Market AlphaDEX(R) ETF and First Trust Dow 30 Equal Weight ETF Creation Units
must pay to BNYM, as transfer agent, a standard creation transaction fee (the
"Creation Transaction Fee"), which is based on the number of different
securities in a Creation Unit of each Fund, according to the fee schedule set
forth below:

                     Number of Securities            Creation
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

The standard creation transaction fee for First Trust Dorsey Wright People's
Portfolio ETF is currently $1,000.

The Creation Transaction Fee is applicable to each purchase transaction
regardless of the number of Creation Units purchased in the transaction. An
additional variable fee of up to three times the Creation Transaction Fee may be
charged to approximate additional expenses incurred by a Fund with respect to
transactions effected outside of the clearing process (i.e., through a DTC
Participant) or to the extent that cash is used in lieu of securities to
purchase Creation Units. The price for each Creation Unit will equal the daily
NAV per Share of a Fund on the transaction date times the number of Shares in a
Creation Unit plus the fees described above and, if applicable, any transfer
taxes.

Authorized Participants redeeming First Trust Total US Market AlphaDEX(R) ETF
and First Trust Dow 30 Equal Weight ETF Creation Units must pay to BNYM, as
transfer agent, a standard redemption transaction fee (the "Redemption
Transaction Fee"), which is based on the number of different securities in a
Creation Unit of each Fund, according to the fee schedule set forth below:

                     Number of Securities           Redemption
                      in a Creation Unit          Transaction Fee
                     --------------------         ---------------
                            1-100                     $  500
                           101-499                    $1,000
                         500 or more                  $1,500

The standard redemption transaction fee for First Trust Dorsey Wright People's
Portfolio ETF is currently $1,000.

The Redemption Transaction Fee is applicable to each redemption transaction
regardless of the number of Creation Units redeemed in the transaction. An
additional variable fee of up to three times the Redemption Transaction Fee may
be charged to approximate additional expenses incurred by a Fund with respect to
redemptions effected outside of the clearing process or to the extent that
redemptions are for cash. Each Fund reserves the right to effect redemptions in
cash. A shareholder may request cash redemption in lieu of securities; however,
a Fund may, in its discretion, reject any such request.

                              6. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Funds, for amounts expended to finance activities primarily intended to result
in the sale of Creation Units or the provision of investor services. FTP may
also use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

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

TO THE SHAREHOLDERS AND THE BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust Total US Market AlphaDEX(R) ETF, First Trust Dorsey Wright People's
Portfolio ETF (formerly known as First Trust CBOE(R) S&P 500(R) VIX(R) Tail
Hedge Fund), and First Trust Dow 30 Equal Weight ETF (the "Funds"), each a
series of the First Trust Exchange-Traded Fund (the "Trust"), including the
portfolios of investments, as of December 31, 2017, the related statements of
operations for the year then ended and the statements of changes in net assets
and the financial highlights for each of the periods presented, and the related
notes. In our opinion, the financial statements and financial highlights present
fairly, in all material respects, the financial position of each of the
portfolios constituting the First Trust Exchange-Traded Fund as of December 31,
2017, and the results of their operations for the year then ended and the
changes in their net assets and the financial highlights for each of the periods
presented, in conformity with accounting principles generally accepted in the
United States of America.

BASIS FOR OPINION

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

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

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements and financial highlights, whether due
to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements and financial highlights. Our audits
also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 2017, by correspondence with
the custodian. We believe that our audits provide a reasonable basis for our
opinion.

We have served as the auditor of one or more First Trust investment companies
since 2001.

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER EACH FUND'S INVESTMENT
OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST
PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS
AND OTHER INFORMATION ABOUT EACH FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUNDS, PLEASE SEE THE FUNDS' STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND.

The following summarizes some of the risks that should be considered for the
Funds.

Each Fund's shares will change in value, and you could lose money by investing
in a Fund. Shares are subject to market fluctuations caused by such factors as
economic, political, regulatory or market developments, changes in interest
rates and perceived trends in stock prices. Overall stock values could decline
generally or could underperform other investments. Overall stock market values
could decline generally or could underperform other investments.

An investment in a Fund involves risks similar to those of investing in any fund
of equity securities traded on an exchange. Investors buying or selling Fund
shares on the secondary market may incur brokerage commissions. In addition,
investors who sell Fund shares may receive less than the Fund shares' net asset
value. Unlike shares of open-end funds, investors are generally not able to
purchase exchange-traded fund ("ETF") shares directly from a Fund and individual
ETF shares are not redeemable. However, specified large blocks of ETF shares
called creation units can be purchased from, or redeemed to, a Fund.

Each Fund is subject to index tracking risk. You should anticipate that the
value of Fund shares will decline, more or less, in correlation with any decline
in the value of the index that the Fund seeks to track.

Each Fund's return may not match the return of the index it seeks to track for a
number of reasons. While First Trust seeks to have a correlation of 0.95 or
better, before expenses, between a Fund's performance and the performance of its
corresponding index, there can be no assurance that a Fund will be able to
achieve such a correlation. Accordingly, each Fund's performance may correlate
to a lesser extent and may possibly vary substantially from the performance of
its corresponding index.


                                                                         Page 51





--------------------------------------------------------------------------------
ADDITIONAL INFORMATION (CONTINUED)
--------------------------------------------------------------------------------

                        FIRST TRUST EXCHANGE-TRADED FUND
                         DECEMBER 31, 2017 (UNAUDITED)

Only a party that has entered into a participation agreement (an "authorized
participant") may engage in creation or redemption transactions directly with
the Funds. The Funds have a limited number of institutions that act as
authorized participants. To the extent that these institutions exit the business
or are unable to proceed with creation and/or redemption orders with respect to
the Funds and no other authorized participant is able to step forward to create
or redeem, in either of these cases, Fund shares may trade at a discount to a
Fund's net asset value and possibly face delisting.

The Funds have become more susceptible to potential operational risks through
breaches in cyber security as the use of Internet technology has become more
prevalent in the course of business. Cyber security breaches may involve
unauthorized access to a Fund's digital information systems or those of a Fund's
third party service providers, such as its administrator, transfer agent,
custodian, or issuers in which a Fund invests. The Funds have established risk
management systems designed to reduce the risks associated with cyber security,
however, there is no guarantee that such efforts will succeed.

Each Fund is also exposed to additional market risk due to a policy of investing
principally in the securities included in its corresponding index. As a result
of such policies, securities held by each Fund will generally not be bought or
sold in response to market fluctuations and the securities may be issued by
companies concentrated in a particular industry. As a result, each Fund will
generally not sell a stock because the stock's issuer is in financial trouble,
unless that stock is removed or is anticipated to be removed from the index the
Fund seeks to track.

Each Fund relies on a license from an index provider that permits the Fund to
use its corresponding index and associated trade names and trademarks in
connection with the name and investment strategies of the Fund. Such licenses
may be terminated by the respective index provider and, as a result, each Fund
may lose its ability to use such intellectual property. There is also no
guarantee that the index provider has all rights to license the respective
intellectual property to First Trust, on behalf of the Fund. Accordingly, in the
event the license is terminated or the index provider does not have rights to
license the particular intellectual property, it may have a significant effect
on the operation of the related Fund.

Each Fund is subject to issuer specific changes risk. The value of an individual
security or a particular type of security can be more volatile than the market
as a whole and can perform differently from the value of the market as a whole.

Each Fund will be concentrated in the securities of companies of a given
industry if the Fund's corresponding index is concentrated in such industry. A
concentration makes a Fund more susceptible to any single occurrence affecting
the related industry and may subject a Fund to greater market risk than less
concentrated funds.

The First Trust Dorsey Wright People's Portfolio ETF and First Trust Dow 30
Equal Weight ETF are each considered to be non-diversified. As a result, the
Funds are exposed to additional market risk. A non-diversified fund may invest a
relatively high percentage of its assets in a limited number of issuers. As a
result, changes in the market value of a single portfolio security could cause
greater fluctuations in share price than would occur in a diversified fund.
Furthermore, non-diversified funds are more susceptible to any single political,
regulatory or economic occurrence.

The Funds are not actively managed. The Funds may be affected by a general
decline in certain market segments relating to their corresponding index. The
Funds invest in securities included in or representative of their corresponding
index regardless of their investment merit. The Funds generally will not attempt
to take defensive positions in declining markets.

The First Trust Total US Market AlphaDEX(R) ETF, First Trust Dorsey Wright
People's Portfolio ETF and First Trust Dow 30 Equal Weight ETF invest in
securities of companies in the information technology industry. Information
technology companies are generally subject to the risks of rapidly changing
technologies; short product life cycles; fierce competition; and aggressive
pricing and reduced profit margins.

The Funds may invest in small capitalization and mid-capitalization companies.
Such companies' securities may be less liquid and may experience greater price
volatility than securities of larger, more established companies.

Because a Fund's corresponding index may include American Depositary Receipts
("ADRs"), American Depositary Shares ("ADSs") and/or stocks of non-U.S.
companies, the investments of the Funds involve risks of investing in non-U.S.
securities that are in addition to the risk associated with domestic securities.
Non-U.S. companies, in general, are not subject to the regulatory requirements
of U.S. companies and, as such, there may be less publicly available information
about these companies. Moreover, non-U.S. accounting, auditing and financial
reporting standards generally are different from those applicable to U.S.
companies. In addition, non-U.S. companies are exposed to additional economic,
political, social or diplomatic events. ADRs and ADSs also involve substantially
identical risks to those associated with investments in non-U.S. securities. In
addition, the issuers of certain depositary receipts, particularly unsponsored
or unregistered depositary receipts, are under no obligation to distribute
shareholder communications to the holders of such receipts, or to pass through
to them any voting rights with respect to the deposited securities.

                         DECEMBER 31, 2017 (UNAUDITED)

Each Fund currently has fewer assets than larger funds and large inflows and
outflows may have a positive or negative impact on the Fund's market exposure
for limited periods of time.

The First Trust Total US Market AlphaDEX(R) ETF invests in consumer
discretionary companies that provide non-essential goods and services directly
to the consumer. The success of these companies is tied closely to the
performance of the overall domestic and international economies, interest rates,
competition, consumer confidence, disposable household income and consumer
spending. Changes in demographics and consumer tastes can affect the demand for
and success of these products.

The First Trust Dorsey Wright People's Portfolio ETF invests in T-Bills whose
income could decline during periods of falling interest rates.

During periods of positive stock market performance, the returns of The First
Trust Dorsey Wright People's Portfolio ETF may be lower if the Fund's net assets
are allocated to T-Bills. Momentum can turn quickly and cause significant
variation from other types of investments.

The First Trust Dorsey Wright People's Portfolio ETF invests in U.S. government
obligations including U.S. Treasury obligations and securities issued or
guaranteed by various agencies of the U.S. government or by various
instrumentalities, which have been established or sponsored by the U.S.
government. U.S. Treasury obligations are back by the "full faith and credit" of
the U.S. government. Securities issued or guaranteed by federal agencies and
U.S. government sponsored instrumentalities may or may not be backed by the full
faith and credit of the U.S. government.

          NOT FDIC INSURED     NOT BANK GUARANTEED     MAY LOSE VALUE

BOARD CONSIDERATIONS REGARDING APPROVAL OF THE INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees (the "Board") of First Trust Exchange-Traded Fund (the
"Trust"), including the Independent Trustees, unanimously approved the
Investment Management Agreement (the "Agreement") with First Trust Advisors L.P.
(the "Advisor"), on behalf of First Trust Dow 30 Equal Weight ETF (the "Fund"),
for an initial two-year term at a meeting held on June 11-12, 2017. The Board
determined that the Agreement is in the best interests of the Fund in light of
the extent and quality of the services expected to be provided and such other
matters as the Board considered to be relevant in the exercise of its reasonable
business judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. To assist the Board in its evaluation of the Agreement for
the Fund, the Independent Trustees received a report from the Advisor in advance
of the Board meeting responding to a request for information provided on behalf
of the Independent Trustees that, among other things, outlined the services to
be provided by the Advisor to the Fund (including the relevant personnel
responsible for these services and their experience); the proposed unitary fee
rate payable by the Fund as compared to fees charged to a peer group of funds
(all of which were exchange-traded funds ("ETFs")) compiled by Management
Practice, Inc. ("MPI"), an independent source (the "MPI Peer Group"), and as
compared to fees charged to other clients of the Advisor, including other ETFs
managed by the Advisor; the estimated expenses of the Fund as compared to the
expense ratios of the funds in the MPI Peer Group; the nature of the expenses to
be incurred in providing services to the Fund and the potential for economies of
scale, if any; financial data on the Advisor; any fall-out benefits to the
Advisor and its affiliate, First Trust Portfolios L.P. ("FTP"); and information
on the Advisor's compliance program. The Independent Trustees also met
separately with their independent legal counsel to discuss the information
provided by the Advisor. The Board applied its business judgment to determine
whether the arrangement between the Trust and the Advisor is a reasonable
business arrangement from the Fund's perspective as well as from the perspective
of shareholders.

In evaluating whether to approve the Agreement for the Fund, the Board
considered the nature, extent and quality of the services to be provided by the
Advisor under the Agreement and considered that employees of the Advisor provide
management services to other ETFs and to other investment companies in the First
Trust fund complex with diligence and care. The Board considered that the
Advisor will be responsible for the overall management and administration of the
Fund and reviewed all of the services to be provided by the Advisor to the Fund.
The Board considered the background and experience of the persons who will be
responsible for the day-to-day management of the Fund. In reviewing the services
to be provided, the Board considered the compliance program that had been
developed by the Advisor and considered that it includes a robust program for
monitoring the Advisor's and the Fund's compliance with the 1940 Act, as well as
the Fund's compliance with its investment objective and policies. Since the Fund
had yet to commence investment operations, the Board could not consider the
historical investment performance of the Fund, but the Board did consider the
hypothetical investment performance of the underlying index. The Board
considered reports it receives on a quarterly basis showing the correlation and
tracking error between other ETFs for which the Advisor serves as investment


                                                                         Page 53

advisor and their applicable underlying indexes. In light of the information
presented and the considerations made, the Board concluded that the nature,
extent and quality of the services to be provided to the Fund by the Advisor
under the Agreement are expected to be satisfactory.

The Board considered the proposed unitary fee rate payable by the Fund under the
Agreement for the services to be provided. The Board noted that, under the
unitary fee arrangement, the Fund would pay the Advisor a unitary fee equal to
an annual rate of 0.50% of its average daily net assets. The Board noted that
the Advisor would be responsible for the Fund's expenses, including the cost of
transfer agency, custody, fund administration, legal, audit and other services
and license fees (if any), but excluding the fee payments under the Agreement,
interest, taxes, brokerage commissions and other expenses connected with the
execution of portfolio transactions, distribution and service fees pursuant to a
Rule 12b-1 plan, if any, and extraordinary expenses. The Board received and
reviewed information for the Fund showing the unitary fee rates and expense
ratios of the peer funds in the MPI Peer Group, as well as advisory fee rates
and expense ratios charged by the Advisor to other fund (including ETFs) and
non-fund clients, as applicable. Because the Fund's MPI Peer Group included peer
funds that pay a unitary fee and because the Fund will pay a unitary fee, the
Board determined that expense ratios were the most relevant comparative data
point. Based on the information provided, the Board noted that the unitary fee
for the Fund was above the median total (net) expense ratio of the peer funds in
its MPI Peer Group. With respect to the MPI Peer Group, the Board discussed with
representatives of the Advisor how the MPI Peer Group was assembled and how the
Fund compared and differed from the peer funds. The Board took these limitations
and differences into account in considering the peer data. With respect to fees
charged to other clients, the Board considered differences between the Fund and
other clients that limited their comparability. The Board noted that the Fund's
unitary fee rate was lower than the total (net) expense ratios of comparable
equal weighted index ETFs advised by the Advisor. In light of the information
considered and the nature, extent and quality of the services expected to be
provided to the Fund under the Agreement, the Board determined that the proposed
unitary fee for the Fund was fair and reasonable.

The Board noted that the proposed unitary fee for the Fund was not structured to
pass the benefits of any economies of scale on to shareholders as the Fund's
assets grow. The Board noted that any reduction in fixed costs associated with
the management of the Fund would benefit the Advisor, but that the unitary fee
structure provides a level of certainty in expenses for the Fund. The Board
noted that the Advisor has continued to invest in personnel and infrastructure
for the First Trust fund complex. The Board took the types of costs to be borne
by the Advisor in connection with its services to be performed for the Fund
under the Agreement into consideration and noted that the Advisor was unable to
estimate the profitability of the Agreement for the Fund to the Advisor. The
Board considered fall-out benefits described by the Advisor that may be realized
from its and FTP's relationship with the Fund. The Board also noted that the
Advisor would not utilize soft dollars in connection with its management of the
Fund's portfolio. The Board concluded that the character and amount of potential
fall-out benefits to the Advisor were not unreasonable.

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

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

      (a) Audit Fees -- The aggregate fees billed for each of the last two
fiscal years for professional services rendered by the principal accountant for

      (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 accountant that are reasonably related to the performance of the audit
of the registrant's financial statements and are not reported under paragraph
(a) of this Item were $1,746 for 2016 and $0 for 2017.

      Audit-Related Fees (Investment Adviser and Distributor) -- The aggregate
fees billed in each of the last two fiscal years for assurance and related
services by the principal accountant that are reasonably related to the
performance of the audit of the registrant's financial statements and are not

      All Other Fees (Investment Adviser and Distributor) -- The aggregate fees
billed in each of the last two fiscal years for products and services provided

this Item were $ 0 for 2016 and $0 for 2017.

      (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 is authorized to give such
pre-approvals on behalf of the Committee up to $25,000 and report any such
pre-approval to the full Committee.

      The Committee is also responsible for the pre-approval of the independent
auditor's engagements for non-audit services with the registrant's 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 its policies, 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 2016 were $55,575
for the registrant, $13,000 for the registrant's investment adviser and $32,500
for the registrant's distributor and for 2017 were $55,575 for the registrant,
$44,000 for the registrant's investment adviser and $63,400 for the registrant's
distributor .

      (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.
