                  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 AlphaDEX(R) 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

                        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 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 ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2019

Dear Shareholders:

One thing we can all agree on and expect: headline news coming out of
Washington, DC continues to influence the financial markets. By late February of
2019, President Trump announced the U.S. was close to a trade deal with China,
yet by May 10, existing tariffs on Chinese imports jumped from 10% to 25%.
Furthermore, the President's threat of additional tariffs on the remaining $300
billion in Chinese imports became a reality with his announcement after a
Federal Funds rate cut of 0.25% on the last day of July. This led many to wonder
if these events could be signaling a recession.

While reticent investors sought cover in "risk-on" assets, calendar year-to-date
performances of broad markets as of July 31, 2019, were strong. Both U.S. and
world equities, as indicated by the S&P 500(R) Index and the MSCI All Country
World Index, returned 20.24% and 16.57%, respectively. Bonds, as measured by the
Bloomberg Barclays U.S. Aggregate Bond Index, returned 6.35%, for the same
period.

Despite the ongoing bluster of the news cycle, we believe the economy is doing
well and productivity growth, due to deregulation and lower taxes on corporate
profits, has improved over the last two years.

      o     The Consumer Confidence Index of 135.7 for July is strong and at the
            highest level this year.

      o     The U.S. inflation rate hovers near 2%, on average, as it has for
            the last decade.

      o     July's unemployment rate of 3.7% barely moved from 3.6% in May,
            which was the lowest level since December of 1969.

Before you head for the exits or reach for the antacids due to the latest
political equivocation, keep a balanced perspective in view. Remember, no one
can predict the inevitable and expected market fluctuations. Speak periodically
with your investment professional, who can provide insight when it comes to
investing and discovering opportunities when they arise.

Thank you for giving First Trust the opportunity to be a part of your financial
plan. We value our relationship with you.

Sincerely,

/s/ James A. Bowen

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

                                 JULY 31, 2019

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 U.S. ECONOMY

The trade conflict between the U.S. and China was nearly 17-months-old at the
close of July 2019. In our opinion, the most notable change from the business
climate of 2018 to that of 2019 was the Trump Administration's ratcheting up of
tariffs on roughly $200 billion of imported goods from China. On May 10, 2019,
tariffs jumped from 10% to 25%. At the end of July, President Trump decided to
up the ante on China by announcing a 10% tariff on the remaining $300 billion or
so in goods shipped to the U.S. annually. The Trump Administration tends to play
the tariff card whenever trade negotiations get bogged down. The tariff was to
begin on September 1, 2019. We learned in August, however, that President Trump
softened his stance by shielding some consumer products from the new tariff
until at least December in order to allow retailers to stock their inventories
for the critical holiday shopping season. The ongoing dispute has become a drag
on global growth, according to organizations such as the International Monetary
Fund.

While the U.S. economy continues to flourish relative to many other developed
and emerging economies, recent data suggests that China's economy is being
stressed by the tariffs. China's gross domestic product rose at an annualized
pace of 6.2% in the second quarter of 2019, the slowest rate of growth in 27
years, according to MarketWatch. CNBC reported that, as of July 1, 2019, the
current U.S. economic expansion will become the longest in its history, breaking
the previous record of 120 months of growth from March 1991 to March 2001,
according to data from the National Bureau of Economic Research.

The recent escalation in the trade conflict between the U.S. and China has
investors flocking to safe-haven assets around the globe, including bonds. One
reflection of this is the market value of the Bloomberg Barclays Global Negative
Yielding Debt Index, which closed the July 31, 2019 trading session at $14.01
trillion, according to Bloomberg. Another is the plunge in the yield on the
benchmark 10-year Treasury Note, which declined by 94 basis points to 2.02% over
the past 12 months. More than half of that drop transpired after mid-April 2019.

ETFGI, an independent research and consultancy firm, reported that total assets
invested in exchange-traded funds ("ETFs") and related exchange-traded products
("ETPs") listed globally stood at an all-time high of $5.74 trillion in July
2019, up from $5.12 trillion a year ago, according to its own release. Total
assets of U.S. listed ETFs/ETPs also stood at an all-time high of $4.02 trillion
for the same period, up from $3.63 trillion a year ago.

SECTOR/EQUITY INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. The flows are reported over
time on a rolling 12-month basis. For the 12-month period ended July 31, 2019,
U.S. Equity funds/ETFs reported estimated net inflows totaling $40.68 billion,
according to data from Morningstar. As has been the case in recent years,
investors are favoring passive funds over actively managed funds. Passive U.S.
Equity funds/ETFs reported estimated net inflows totaling $242.78 billion,
compared to estimated net outflows totaling $202.10 billion for actively managed
U.S. Equity funds/ETFs, for the same period.

Investors shied away from sector funds and sector ETFs. For the 12-month period
ended July 31, 2019, Sector Equity funds/ETFs reported estimated net outflows
totaling $50.79 billion. Passive Sector Equity funds/ETFs reported estimated net
outflows totaling $20.18 billion, compared to estimated net outflows totaling
$30.61 billion for actively managed Sector Equity funds/ETFs for the same
period.

For the 12-month period ended July 31, 2019, nine of the 11 major sectors that
comprise the S&P 500(R) Index generated positive total returns, according to
Bloomberg. The S&P 500(R) Index posted a total return of 7.99% over the period.
Six of the 11 sectors outperformed the broader index. Those six sectors were as
follows: Real Estate (+17.56%); Utilities (+16.53%); Information Technology
(+15.72%); Communication Services (+14.82%); Consumer Staples (+14.64%); and
Consumer Discretionary (+9.22%), according to Bloomberg. The two sectors that
posted negative total returns for the period were Materials, down 0.14%, and
Energy, down 15.99%.


                                                                          Page 3

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

FIRST TRUST CONSUMER DISCRETIONARY ALPHADEX(R) FUND (FXD)

The First Trust Consumer Discretionary AlphaDEX(R) 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 StrataQuant(R) Consumer
Discretionary Index (the "Consumer Discretionary Index"). The Fund will normally
invest at least 90% of its net assets (including investment borrowings) in
common stocks that comprise the Consumer Discretionary Index. The shares of the
Fund are listed and trade on the NYSE Arca, Inc. (the "NYSE Arca" or the
"Exchange") under the ticker symbol "FXD."

The Consumer Discretionary Index is a modified equal-dollar weighted index
designed by ICE Data Indices, LLC. or its affiliates ("IDI") to objectively
identify and select stocks from the Russell 1000(R) Index in the consumer
discretionary sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Consumer
Discretionary Index using the Russell Global Sectors (the "RGS") sector scheme
to determine a stock's sector membership.

(1) On or about September 18, 2008, Russell Investment Group ("Russell") began
calculating its Russell U.S. Indices using an enhanced Russell sector scheme,
the RGS. The RGS and the former U.S. sector scheme ran in tandem until June 30,
2009, when Russell officially transitioned to the RGS and ceased calculating its
indices using the U.S. sector scheme. In addition to the implementation of the
RGS, Russell changed the name of the Russell 1000(R) Consumer Discretionary and
Services Index to the Russell 1000(R) Consumer Discretionary Index.
Consequently, performance data is not available for all the periods shown in the
table for the Russell 1000(R) Consumer Discretionary Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

The StrataQuant(R) Consumer Discretionary Index is a registered trademark of IDI
and has been licensed for use by First Trust Portfolios L.P., which has
sub-licensed the Index for use by the Fund. The Fund is not sponsored, endorsed,
sold or promoted by IDI, and IDI makes no representation or warranty regarding
the advisability of investing in the Fund or as to the result to be obtained by
any person from use of the StrataQuant(R) Consumer Discretionary Index in
connection with the trading of the Fund.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 CONSUMER STAPLES ALPHADEX(R) FUND (FXG)

The First Trust Consumer Staples AlphaDEX(R) 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 StrataQuant(R) Consumer Staples
Index (the "Consumer Staples Index"). The Fund will normally invest at least 90%
of its net assets (including investment borrowings) in common stocks that
comprise the Consumer Staples Index. The shares of the Fund are listed and trade
on the NYSE Arca under the ticker symbol "FXG."

The Consumer Staples Index is a modified equal-dollar weighted index designed by
IDI to objectively identify and select stocks from the Russell 1000(R) Index in
the consumer staples sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Consumer Staples Index using the RGS sector scheme to determine a stock's
sector membership.

PERFORMANCE REVIEW

FXG's one-year NAV return of 0.83% underperformed the S&P 500(R) Consumer
Staples Index ("Benchmark") return of 14.64% by 13.81%. Over the period, the
Food Products industry was given the greatest allocation in the Fund with a
weighting of 53.8%. With a return of 5.7% and contribution of 3.3% to the Fund's
total return, this industry was the greatest positive contributor to the Fund's
return. The Food & Staples Retailing industry caused the greatest drag in the
portfolio, with a weight of 20.5%, return of -6.2%, and contribution to the
Fund's return of -1.6%. The Fund underperformed the Benchmark during the period.
The Household Products industry caused the most underperformance. The Benchmark
allocated 22.3% to this industry, in contrast with the Fund's 10.2%, and these
investments in the Benchmark returned 35%, while Household Products in the Fund
returned 9.0%. In all, Household Products accounted for -4.3% underperformance
in the Fund. The greatest outperformance for the Fund came simply by investing
very little in the Tobacco industry. This industry was very nearly absent from
the Fund, with an average allocation of only 0.5%, and earned 2.3%
outperformance in the Fund versus the Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Consumer Staples Index because

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 ENERGY ALPHADEX(R) FUND (FXN)

The First Trust Energy AlphaDEX(R) 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 StrataQuant(R) Energy Index (the "Energy
Index"). The Fund will normally invest at least 90% of its net assets (including
investment borrowings) in common stocks that comprise the Energy Index. The
shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol
"FXN."

The Energy Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
energy sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Energy Index
using the RGS sector scheme to determine a stock's sector membership.

PERFORMANCE REVIEW

FXN's one-year NAV return of -35.77% underperformed the S&P 500(R) Energy Index
("Benchmark") return of -15.99% by 19.78%. The Oil, Gas, & Consumable Fuels
industry was given by far the greatest allocation in the Fund and caused
significant negative performance in the Fund. The allocation of 84.9% performed
-36.3%, contributing -30.9% to the Fund's total return. The best-returning
industry was the Chemicals industry, with a performance of -5.3%. With a meager
0.2% allocation, this industry contributed essentially nothing to the Fund's
return (-2 basis points over the year). The Fund underperformed the Benchmark
during the period. The heavily weighted Oil, Gas, & Consumable Fuels industry
contributed -21% to this underperformance, while Energy Equipment & Services and
Chemicals created 0.6% and 0.5% outperformance, respectively.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. In addition to the implementation of the RGS, Russell combined the
Russell 1000(R) Integrated Oils Index and the Russell 1000(R) Other Energy Index
into one index, the Russell 1000(R) Energy Index. Consequently, performance data
is not available for all the periods shown in the table for the Russell 1000(R)
Energy Index because this index did not exist until on or about September 18,
2008.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 FINANCIALS ALPHADEX(R) FUND (FXO)

The First Trust Financials AlphaDEX(R) 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 StrataQuant(R) Financials Index (the
"Financials Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in common stocks that comprise the
Financials Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXO."

The Financials Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
financial services sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Financials Index using the RGS sector scheme to determine a stock's sector
membership.

which caused -1.0% underperformance.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Financial Services Index because
performance data does not exist for each of the entire periods using solely the
U.S. sector scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 HEALTH CARE ALPHADEX(R) FUND (FXH)

The First Trust Health Care AlphaDEX(R) 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 StrataQuant(R) Health Care Index
(the "Health Care Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in common stocks that comprise the
Health Care Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXH."

The Health Care Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
health care sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Health Care
Index using the RGS sector scheme to determine a stock's sector membership.

greatest allocation was Health Care Providers and Services, with a 27.5% average
weight over the period. This industry performed -3.3% and contributed -1.7% to
the Fund's total performance. This -1.7% contribution was the greatest drag on
the Fund's performance during the period. The greatest contributor to the Fund's

and Supplies caused -1.4% underperformance for the Fund.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Health Care Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 INDUSTRIALS/PRODUCER DURABLES ALPHADEX(R) FUND (FXR)

The First Trust Industrials/Producer Durables AlphaDEX(R) 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
StrataQuant(R) Industrials Index (the "Industrials Index"). The Fund will
normally invest at least 90% of its net assets (including investment borrowings)
in common stocks that comprise the Industrials Index. The shares of the Fund are
listed and trade on the NYSE Arca under the ticker symbol "FXR."

The Industrials Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
industrials and producer durables sector that may generate positive alpha
relative to traditional passive-style indices through the use of the AlphaDEX(R)
selection methodology. Alpha is an indication of how much an investment
outperforms or underperforms on a risk-adjusted basis relative to its benchmark.
IDI constructs the Industrials Index using the RGS sector scheme to determine a
stock's sector membership.

PERFORMANCE REVIEW

FXR's one-year NAV return of 3.67% outperformed the S&P 500(R) Industrials Index
("Benchmark") return of 3.58% by 0.09%. The Machinery industry carried the most
weight in the Fund during the period. With an average weight of 19.9% and a
performance of -3.2%, this industry contributed -1.1% to the Fund's total
return. The best industry for the Fund during this period was Commercial
Services & Supplies, which received a 6.4% allocation, experienced 22.8%
performance and contributed 2% to the Fund's total return. The worst drag on the
Fund was from Trading Companies & Distributors. Investments in this industry
accounted for -1.3% of the Fund's performance. The Fund outperformed the
Benchmark during the period. The outperformance of 1.7% is attributable to
investments in the Industrial Conglomerates industry, which was a drag on the
Benchmark but was barely represented in the Fund. The greatest source of
underperformance were the investments in the Machinery industry, which caused
-1.5% underperformance against the Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Producer Durables Index because
performance data does not exist for each of the entire periods using solely the
U.S. sector scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 MATERIALS ALPHADEX(R) FUND (FXZ)

The First Trust Materials AlphaDEX(R) 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 StrataQuant(R) Materials Index (the
"Materials Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Materials
Index. The shares of the Fund are listed and trade on the NYSE Arca under the
ticker symbol "FXZ."

The Materials Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
materials and processing sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Materials Index using the RGS sector scheme to determine a stock's sector
membership.

PERFORMANCE REVIEW

FXZ's one-year NAV return of -10.08% underperformed the S&P 500(R) Materials
Index ("Benchmark") return of -0.14% by 9.94%. With an average weight of 35.8%,
the Chemicals industry was the largest allocation in the Fund. Investments in
Chemicals performed -12.5% and contributed -4.4% to the Fund's total return. The
greatest drag on portfolio performance, however, were investments in the Metals
& Mining industry, which received an allocation of 18.7% and caused a -6.7%
return in the Fund. The greatest contributor to the Fund's performance were the
investments in the Building Products industry, which carried an average weight
of 6.4% and contributed 1.4% to the Fund's total return. The Fund underperformed
the Benchmark during the period. The vast majority of this underperformance is
attributable to investments in Metals and Mining, with -4.5% underperformance,
and Chemicals with -3.9% underperformance against the Benchmark. The Building
Products industry, meanwhile, caused 1.1% outperformance against the Benchmark
during the period.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Materials and Processing Index
because performance data does not exist for each of the entire periods using
solely the U.S. sector scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 TECHNOLOGY ALPHADEX(R) FUND (FXL)

The First Trust Technology AlphaDEX(R) 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 StrataQuant(R) Technology Index (the
"Technology Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in common stocks that comprise the
Technology Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXL."

The Technology Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
technology sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Technology
Index using the RGS sector scheme to determine a stock's sector membership.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Technology Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 UTILITIES ALPHADEX(R) FUND (FXU)

The First Trust Utilities AlphaDEX(R) 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 StrataQuant(R) Utilities Index (the
"Utilities Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in common stocks that comprise the Utilities
Index. The shares of the Fund are listed and trade on the NYSE Arca under the
ticker symbol "FXU."

The Utilities Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
utilities sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Utilities

PERFORMANCE REVIEW

FXU's one-year NAV return of 11.71% underperformed the S&P 500(R) Utilities
Index ("Benchmark") return of 16.53% by 4.82%. The Electric Utilities industry
received the largest allocation during the period, performed at 15.4%, and
contributed more than any other industry to the Fund's total performance,
contributing 5.5% to the Fund's total return. The sector with the greatest drag
in the Fund was Independent Power & Renewable Electricity Producers, which
received a 1.1% allocation and contributed -0.4% to the Fund's total return. The
Fund underperformed the Benchmark during the period. Much of this
underperformance is attributable to the investments in Diversified
Telecommunications Services, which received 14.5% allocation in the Fund, was
absent in the Benchmark, and caused -2.9% underperformance against the
Benchmark. The most outperformance came from investments in Wireless
Telecommunication Services, which was also absent from the Benchmark, and
garnered 1.8% outperformance relative to the Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Utilities Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 period 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 May 8, 2007
(inception) to May 10, 2007 (the first day of secondary market trading) 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 ALPHADEX(R) FUND

SECTOR FUNDS
UNDERSTANDING YOUR FUND EXPENSES
JULY 31, 2019 (UNAUDITED)

As a shareholder of First Trust Consumer Discretionary AlphaDEX(R) Fund, First
Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund,
First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R)
Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust
Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund or First
Trust Utilities AlphaDEX(R) 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 July 31, 2019.

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.

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2019

                                1. ORGANIZATION

First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") is an open-end
management investment company organized as a Massachusetts business trust on
December 6, 2006, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty-one exchange-traded funds considered
either a Sector Fund or a Style Fund. This report covers the nine Sector Funds
listed below. The shares of each Sector Fund are listed and traded on NYSE Arca,
Inc.

    First Trust Consumer Discretionary AlphaDEX(R) Fund - (ticker "FXD")
    First Trust Consumer Staples AlphaDEX(R) Fund - (ticker "FXG")
    First Trust Energy AlphaDEX(R) Fund - (ticker "FXN")
    First Trust Financials AlphaDEX(R) Fund - (ticker "FXO")
    First Trust Health Care AlphaDEX(R) Fund - (ticker "FXH")
    First Trust Industrials/Producer Durables AlphaDEX(R) Fund - (ticker "FXR")
    First Trust Materials AlphaDEX(R) Fund - (ticker "FXZ")
    First Trust Technology AlphaDEX(R) Fund - (ticker "FXL")
    First Trust Utilities AlphaDEX(R) Fund - (ticker "FXU")

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." Each Fund's 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 ("FASB")
Accounting Standards Codification ("ASC") 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'


                                                                         Page 57

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2019

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

      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 ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2019

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 July 31, 2019, 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
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.

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 fees received from the securities lending agent are accrued daily. The
dividend and interest earned on the securities loaned is accounted for in the
same manner as other dividend and interest income. At July 31, 2019, only FXN
and FXR had securities in the securities lending program. During the fiscal year
ended July 31, 2019, all the Funds participated 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.


                                                                         Page 59

                                 JULY 31, 2019

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
maintain 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 fiscal year ended July 31, 2019, 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 net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying
treatment of income and gain/loss on significantly modified portfolio securities
held by the Funds and have no impact on net assets or NAV per share. Temporary
differences, which arise from recognizing certain items of income, expense and
gain/loss in different periods for financial statement and tax purposes, will
reverse at some time in the future.

The tax character of distributions paid by each Fund during the fiscal year
ended July 31, 2019 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 2016, 2017,
2018, and 2019 remain open to federal and state audit. As of July 31, 2019,
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 beginning 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 July 31, 2019, the Funds had 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.



                                                                             Post Enactment -

                                 JULY 31, 2019

Certain losses realized during the current fiscal year may be deferred and
treated as occurring on the first day of the following fiscal year for federal
income tax purposes. For the fiscal year ended July 31, 2019, the following Fund
listed below incurred and elected to defer net late year ordinary or capital
losses as follows:



                                                                   Qualified Late Year Losses

In order to present paid-in capital and accumulated distributable earnings
(loss) (which consists of accumulated net investment income (loss), accumulated
net realized gain (loss) on investments and net unrealized appreciation
(depreciation) 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 fiscal
year ended July 31, 2019, the adjustments for each Fund were as follows:



                                                                                      Accumulated

H. EXPENSES

Expenses that are directly related to one of the Funds are charged directly to
the respective Fund. General expenses of the Trust are allocated to all the
Funds based upon the net assets of each Fund.

FTP has entered into licensing agreements with IDI for each of the Funds. The
license agreements allow for the use by FTP of certain trademarks and trade
names of IDI. The Funds and First Trust are sub-licensees to the license
agreement. The Funds are required to pay licensing fees, which are shown on the
Statements of Operations.

I. NEW ACCOUNTING PRONOUNCEMENT

On August 28, 2018, the FASB issued Accounting Standards Update ("ASU") 2018-13,
"Disclosure Framework - Changes to the Disclosure Requirements for Fair Value
Measurement," which amends the fair value measurement disclosure requirements of
ASC 820. The amendments of ASU 2018-13 include new, eliminated, and modified
disclosure requirements of ASC 820. In addition, the amendments clarify that
materiality is an appropriate consideration of entities when evaluating
disclosure requirements. The ASU is effective for fiscal years beginning after
December 15, 2019, including interim periods therein. Early adoption is
permitted for any eliminated or modified disclosures upon issuance of this ASU.
The Funds have early adopted ASU 2018-13 for these financial statements, which
did not result in a material impact.

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

First Trust, the investment advisor to the Funds, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the selection and ongoing monitoring of the securities
in each Fund's portfolio, managing the Fund's business affairs and providing
certain administrative services necessary for the management of the Funds.

For these services, First Trust is paid an annual management fee of 0.50% of
each Fund's average daily net assets. The Trust and First Trust 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 each 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 November 30, 2020.

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 or expense was incurred, but no reimbursement payment will be made by a Fund
if it results in the Fund exceeding its Expense Cap. These amounts would be
included in "Expenses previously waived or reimbursed" on the Statements of
Operations.

For the fiscal year ended July 31, 2019, there were no fees waived or expenses
reimbursed by First Trust for the Funds. As of July 31, 2019, none of the Funds
had previously waived fees 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.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2019

                  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

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 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 November 30, 2020.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

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

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

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
ALPHADEX(R) FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples
AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials
AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust
Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials
AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund, and First Trust
Utilities AlphaDEX(R) Fund (the "Funds"), each a series of the First Trust
Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the portfolios of
investments, as of July 31, 2019, 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, and 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 nine portfolios included within
the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2019, 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 its 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 July 31, 2019, 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 ALPHADEX(R) FUND
                                  SECTOR FUNDS
                           JULY 31, 2019 (UNAUDITED)


                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE
APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS
RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW
APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT
IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY
FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE,
RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF
ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT
WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO
REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND.

CONCENTRATION RISK. To the extent that a fund is able to invest a large
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
not concentrated.

CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable
or unwilling to make dividend, interest and/or principal payments when due and
the related risk that the value of a security may decline because of concerns
about the issuer's ability to make such payments.

CYBER SECURITY RISK. The funds are susceptible to potential operational risks
through breaches in cyber security. A breach in cyber security refers to both
intentional and unintentional events that may cause a fund to lose proprietary
information, suffer data corruption or lose operational capacity. Such events
could cause a fund to incur regulatory penalties, reputational damage,
additional compliance costs associated with corrective measures and/or financial
loss. In addition, cyber security breaches of a fund's third-party service
providers, such as its administrator, transfer agent, custodian, or sub-advisor,
as applicable, or issuers in which the fund invests, can also subject a fund to
many of the same risks associated with direct cyber security breaches.

DERIVATIVES RISK. To the extent a fund uses derivative instruments such as
futures contracts, options contracts and swaps, the fund may experience losses
because of adverse movements in the price or value of the underlying asset,
index or rate, which may be magnified by certain features of the derivative.
These risks are heightened when a fund's portfolio managers use derivatives to
enhance the fund's return or as a substitute for a position or security, rather
than solely to hedge (or offset) the risk of a position or security held by the
fund.

EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the
value of the fund's shares will fluctuate with changes in the value of the
equity securities. Equity securities prices fluctuate for several reasons,
including changes in investors' perceptions of the financial condition of an
issuer or the general condition of the relevant stock market, such as market
volatility, or when political or economic events affecting the issuers occur. In
addition, common stock prices may be particularly sensitive to rising interest
rates, as the cost of capital rises and borrowing costs increase. Equity
securities may decline significantly in price over short or extended periods of
time, and such declines may occur in the equity market as a whole, or they may
occur in only a particular country, company, industry or sector of the market.

ETF RISK. The shares of an ETF trade like common stock and represent an interest
in a portfolio of securities. The risks of owning an ETF generally reflect the
risks of owning the underlying securities, although lack of liquidity in an ETF
could result in it being more volatile and ETFs have management fees that
increase their costs. Shares of an ETF trade on an exchange at market prices
rather than net asset value, which may cause the shares to trade at a price
greater than net asset value (premium) or less than net asset value (discount).
In times of market stress, decisions by market makers to reduce or step away
from their role of providing a market for an ETF's shares, or decisions by an
ETF's authorized participants that they are unable or unwilling to proceed with
creation and/or redemption orders of an ETF's shares, could result in shares of
the ETF trading at a discount to net asset value and in greater than normal
intraday bid-ask spreads.

FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income
securities, the fund will be subject to credit risk, income risk, interest rate
risk, liquidity risk and prepayment risk. Income risk is the risk that income
from a fund's fixed income investments could decline during periods of falling
interest rates. Interest rate risk is the risk that the value of a fund's fixed
income securities will decline because of rising interest rates. Liquidity risk
is the risk that a security cannot be purchased or sold at the time desired, or
cannot be purchased or sold without adversely affecting the price. Prepayment
risk is the risk that the securities will be redeemed or prepaid by the issuer,
resulting in lower interest payments received by the fund. In addition to these
risks, high yield securities, or "junk" bonds, are subject to greater market
fluctuations and risk of loss than securities with higher ratings, and the
market for high yield securities is generally smaller and less liquid than that
for investment grade securities.

                           JULY 31, 2019 (UNAUDITED)

INDEX CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. As a result, such a fund may be included in one or more index-tracking
exchange-traded funds or mutual funds. Being a component security of such a
vehicle could greatly affect the trading activity involving a fund, the size of
the fund and the market volatility of the fund. Inclusion in an index could
significantly increase demand for the fund and removal from an index could
result in outsized selling activity in a relatively short period of time. As a
result, a fund's net asset value could be negatively impacted and the fund's
market price may be significantly below its net asset value during certain
periods.

INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject
to Index Provider Risk. There is no assurance that the Index Provider will
compile the Index accurately, or that the Index will be determined, maintained,
constructed, reconstituted, rebalanced, composed, calculated or disseminated
accurately. To correct any such error, the Index Provider may carry out an
unscheduled rebalance or other modification of the Index constituents or
weightings, which may increase the fund's costs. The Index Provider does not
provide any representation or warranty in relation to the quality, accuracy or
completeness of data in the Index, and it does not guarantee that the Index will
be calculated in accordance with its stated methodology. Losses or costs
associated with any Index Provider errors generally will be borne by the fund
and its shareholders.

INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of
other investment vehicles, the fund will incur additional fees and expenses that
would not be present in a direct investment in those investment vehicles.
Furthermore, the fund's investment performance and risks are directly related to
the investment performance and risks of the investment vehicles in which the
fund invests.

MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to
management risk. In managing an actively-managed fund's investment portfolio,
the fund's portfolio managers will apply investment techniques and risk analyses
that may not have the desired result. There can be no guarantee that a fund will
meet its investment objective.

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations.

NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities,
it is subject to additional risks not associated with securities of domestic
issuers. Non-U.S. securities are subject to higher volatility than securities of
domestic issuers due to: possible adverse political, social or economic
developments; restrictions on foreign investment or exchange of securities; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; different legal or accounting standards; and less government supervision
and regulation of exchanges in foreign countries. Investments in non-U.S.
securities may involve higher costs than investments in U.S. securities,
including higher transaction and custody costs, as well as additional taxes
imposed by non-U.S. governments. These risks may be heightened for securities of
companies located, or with significant operations, in emerging market countries.

PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund
will invest in the securities included in, or representative of, the index
regardless of their investment merit. A fund generally will not attempt to take
defensive positions in declining markets.

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 AlphaDEX(R) Fund 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, 2018, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $3,416,811.
This figure is comprised of $149,724 paid (or to be paid) in fixed compensation
and $3,267,087 paid (or to be paid) in variable compensation. There were a total
of 14 beneficiaries of the remuneration described above. Those amounts include
$2,169,857 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $1,246,954 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.

                               ADVISORY AGREEMENT

 BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees (the "Board") of First Trust Exchange-Traded AlphaDEX(R)
Fund (the "Trust"), including the Independent Trustees, unanimously approved the
continuation of the Investment Management Agreement (the "Agreement") with First
Trust Advisors L.P. (the "Advisor") on behalf of the following nine series of
the Trust (each a "Fund" and collectively, the "Funds"):

         First Trust Consumer Discretionary AlphaDEX(R) Fund (FXD)
         First Trust Consumer Staples AlphaDEX(R) Fund (FXG)
         First Trust Energy AlphaDEX(R) Fund (FXN)
         First Trust Financials AlphaDEX(R) Fund (FXO)
         First Trust Health Care AlphaDEX(R) Fund (FXH)
         First Trust Industrials/Producer Durables AlphaDEX(R) Fund (FXR)
         First Trust Materials AlphaDEX(R) Fund (FXZ)
         First Trust Technology AlphaDEX(R) Fund (FXL)
         First Trust Utilities AlphaDEX(R) Fund (FXU)

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2020 at a meeting held on June 2, 2019. The
Board determined for each Fund that the continuation of the Agreement is in the
best interests of the Fund in light of the nature, extent and quality of the
services provided and such other matters as the Board considered to be relevant
in the exercise of its reasonable business judgment.

To reach this determination for each Fund, 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. At meetings held on April 18, 2019 and June 2, 2019, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to the Independent
Trustees, submitted on behalf of the Independent Trustees, that, among other
things, outlined: the services provided by the Advisor to each Fund (including
the relevant personnel responsible for these services and their experience); the
advisory fee rate payable by each Fund as compared to fees charged to a peer
group of funds (the "Expense Group") and a broad peer universe of funds (the
"Expense Universe"), each assembled by Broadridge Financial Solutions, Inc.
("Broadridge"), an independent source, and as compared to fees charged to other
clients of the Advisor, including other exchange-traded funds ("ETFs") managed
by the Advisor; the expense ratio of each Fund as compared to expense ratios

                           JULY 31, 2019 (UNAUDITED)

of the funds in the Fund's Expense Group and Expense Universe; performance
information for each Fund, including comparisons of each Fund's performance to
that of one or more relevant benchmark indexes and to that of a performance
group of funds and a broad performance universe of funds (the "Performance
Universe"), each assembled by Broadridge; the nature of expenses incurred in
providing services to each 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 Board reviewed initial materials with the Advisor at the
meeting held on April 18, 2019, prior to which the Independent Trustees and
their counsel met separately to discuss the information provided by the Advisor.
Following the April meeting, independent legal counsel on behalf of the
Independent Trustees requested certain clarifications and supplements to the
materials provided, and the information provided in response to those requests
was considered at an executive session of the Independent Trustees and
independent legal counsel held prior to the June 2, 2019 meeting, as well as at
the meeting held that day. The Board applied its business judgment to determine
whether the arrangement between the Trust and the Advisor continues to be a
reasonable business arrangement from each Fund's perspective. The Board
determined that, given the totality of the information provided with respect to
the Agreement, the Board had received sufficient information to renew the
Agreement. The Board considered that shareholders chose to invest or remain
invested in a Fund knowing that the Advisor manages the Fund and knowing the
Fund's advisory fee.

In reviewing the Agreement for each Fund, the Board considered the nature,
extent and quality of the services provided by the Advisor under the Agreement.
The Board considered that the Advisor is responsible for the overall management
and administration of the Trust and each Fund and reviewed all of the services
provided by the Advisor to the Funds, as well as the background and experience
of the persons responsible for such services. In reviewing the services
provided, the Board noted the compliance program that had been developed by the
Advisor and considered that it includes a robust program for monitoring the
Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's
compliance with its investment objective, policies and restrictions. The Board
also considered a report from the Advisor with respect to its risk management
functions related to the operation of the Funds. Finally, as part of the Board's
consideration of the Advisor's services, the Advisor, in its written materials
and at the April 18, 2019 meeting, described to the Board the scope of its
ongoing investment in additional infrastructure and personnel to maintain and
improve the quality of services provided to the Funds and the other funds in the
First Trust Fund Complex. In light of the information presented and the
considerations made, the Board concluded that the nature, extent and quality of
the services provided to the Trust and each Fund by the Advisor under the
Agreement have been and are expected to remain satisfactory and that the Advisor
has managed each Fund consistent with its investment objective, policies and
restrictions.

The Board considered the advisory fee rate payable by each Fund under the
Agreement for the services provided. The Board considered that the Advisor
agreed to extend the current expense cap for each Fund through November 30,
2020. For each Fund, the Board noted that expenses borne or fees waived by the
Advisor are to be subject to reimbursement by the Fund for up to three years
from the date the expense was incurred or fee was waived, but no reimbursement
payment would be made by the Fund if it would result in the Fund exceeding an
expense ratio equal to the expense cap in place at the time the expenses were
borne or fees were waived by the Advisor. The Board received and reviewed
information showing the advisory or unitary fee rates and expense ratios of the
peer funds in the Expense Groups, as well as advisory and unitary fee rates
charged by the Advisor to other fund (including ETFs) and non-fund clients, as
applicable. Because each Fund's Expense Group included peer funds that 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 total (net) expense ratio of each Fund was above the median total (net)
expense ratio of the peer funds in its respective Expense Group. With respect to
the Expense Groups, the Board, at the April 18, 2019 meeting, discussed with
Broadridge its methodology for assembling peer groups and discussed with the
Advisor limitations in creating peer groups for index ETFs, including
differences in underlying indexes and index-tracking methodologies that can
result in greater management complexities across seemingly comparable ETFs, and
different business models that may affect the pricing of services among ETF
sponsors. The Board took these limitations and differences into account in
considering the peer data. With respect to fees charged to other non-ETF
clients, the Board considered differences between the Funds and other non-ETF
clients that limited their comparability. In considering the advisory fee rates
overall, the Board also considered the Advisor's statement that it seeks to meet
investor needs through innovative and value-added investment solutions and the
Advisor's description of its long-term commitment to each Fund.

The Board considered performance information for each Fund. The Board noted the
process it has established for monitoring each Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Funds. The Board determined that this process continues to
be effective for reviewing each Fund's performance. The Board received and
reviewed information for periods ended December 31, 2018 regarding the
performance of each Fund's underlying index, the correlation between each Fund's
performance and that of its underlying index, each Fund's tracking difference
and each Fund's excess return as compared to its benchmark index. The Board
considered the Advisor's explanations of how the AlphaDEX(R) stock selection
methodology impacts Fund performance in various market environments, and the
Advisor's statement that AlphaDEX(R) is designed to provide long-term
outperformance. Based on the information provided and its ongoing review of
performance, the Board concluded that each Fund was correlated to its underlying
index and that the tracking difference for each Fund was within a reasonable

range. In addition, the Board reviewed data prepared by Broadridge comparing
each Fund's performance to that of its respective Performance Universe and to
that of a broad-based benchmark index, but given each Fund's objective of
seeking investment results that correspond generally to the performance of its
underlying index, the Board placed more emphasis on its review of correlation
and tracking difference.

On the basis of all the information provided on the fees, expenses and
performance of each Fund and the ongoing oversight by the Board, the Board
concluded that the advisory fee for each Fund continues to be reasonable and
appropriate in light of the nature, extent and quality of the services provided
by the Advisor to each Fund under the Agreement.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Funds and noted the Advisor's statement that it believes its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Funds. The Board considered the revenues and allocated costs
(including the allocation methodology) of the Advisor in serving as investment
advisor to each Fund for the twelve months ended December 31, 2018 and the
estimated profitability level for each Fund calculated by the Advisor based on
such data, as well as complex-wide and product-line profitability data for the
same period. The Board noted the inherent limitations in the profitability
analysis and concluded that, based on the information provided, the Advisor's
profitability level for each Fund was not unreasonable. In addition, the Board
considered fall-out benefits described by the Advisor that may be realized from
its relationship with the Funds. The Board considered that the Advisor had
identified as a fall-out benefit to the Advisor and FTP their exposure to
investors and brokers who, absent their exposure to the Funds, may have had no
dealings with the Advisor or FTP, and noted that the Advisor does not utilize
soft dollars in connection with the Funds. 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 continue to be fair and reasonable and that the continuation of
the Agreement is in the best interests of each Fund. No single factor was
determinative in the Board's analysis.

                  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 AlphaDEX(R) 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 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.

SHAREHOLDER LETTER

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2019

Dear Shareholders:

One thing we can all agree on and expect: headline news coming out of
Washington, DC continues to influence the financial markets. By late February of
2019, President Trump announced the U.S. was close to a trade deal with China,
yet by May 10, existing tariffs on Chinese imports jumped from 10% to 25%.
Furthermore, the President's threat of additional tariffs on the remaining $300
billion in Chinese imports became a reality with his announcement after a
Federal Funds rate cut of 0.25% on the last day of July. This led many to wonder
if these events could be signaling a recession.

While reticent investors sought cover in "risk-on" assets, calendar year-to-date
performances of broad markets as of July 31, 2019, were strong. Both U.S. and
world equities, as indicated by the S&P 500(R) Index and the MSCI All Country
World Index, returned 20.24% and 16.57%, respectively. Bonds, as measured by the
Bloomberg Barclays U.S. Aggregate Bond Index, returned 6.35%, for the same
period.

Despite the ongoing bluster of the news cycle, we believe the economy is doing
well and productivity growth, due to deregulation and lower taxes on corporate
profits, has improved over the last two years.

      o     The Consumer Confidence Index of 135.7 for July is strong and at the
            highest level this year.

      o     The U.S. inflation rate hovers near 2%, on average, as it has for
            the last decade.

      o     July's unemployment rate of 3.7% barely moved from 3.6% in May,
            which was the lowest level since December of 1969.

Before you head for the exits or reach for the antacids due to the latest
political equivocation, keep a balanced perspective in view. Remember, no one
can predict the inevitable and expected market fluctuations. Speak periodically
with your investment professional, who can provide insight when it comes to
investing and discovering opportunities when they arise.

Thank you for giving First Trust the opportunity to be a part of your financial
plan. We value our relationship with you.

Sincerely,

/s/ James A. Bowen

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

                                 JULY 31, 2019

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

Street Reporter, Bloomberg News Service, and Registered Rep.

STATE OF THE U.S./GLOBAL ECONOMY

The trade conflict between the U.S. and China was nearly 17-months-old at the
close of July 2019. In our opinion, the most notable change from the business
climate of 2018 to that of 2019 was the Trump Administration's ratcheting up of
tariffs on roughly $200 billion of imported goods from China. On May 10, 2019,
tariffs jumped from 10% to 25%. At the end of July, President Trump decided to
up the ante on China by announcing a 10% tariff on the remaining $300 billion or
so in goods shipped to the U.S. annually. The Trump Administration tends to play
the tariff card whenever trade negotiations get bogged down. The tariff was to
begin on September 1, 2019. We learned in August, however, that President Trump
softened his stance by shielding some consumer products from the new tariff
until at least December in order to allow retailers to stock their inventories
for the critical holiday shopping season. The ongoing dispute has become a drag
on global growth, according to such organizations as the International Monetary
Fund.

While the U.S. economy continues to flourish relative to many other developed
and emerging economies, recent data suggests that China's economy is being
stressed by the tariffs. China's gross domestic product rose at an annualized
pace of 6.2% in the second quarter of 2019, the slowest rate of growth in 27
years, according to MarketWatch. CNBC reported that, as of July 1, 2019, the
current U.S. economic expansion will become the longest in its history, breaking
the previous record of 120 months of growth from March 1991 to March 2001,
according to data from the National Bureau of Economic Research.

The recent escalation in the trade conflict between the U.S. and China has
investors flocking to safe-haven assets around the globe, including bonds. One
reflection of this is the market value of the Bloomberg Barclays Global Negative
Yielding Debt Index, which closed the July 31, 2019 trading session at $14.01
trillion, according to Bloomberg. Another is the plunge in the yield on the
benchmark 10-year Treasury Note, which declined by 94 basis points to 2.02% over
the past 12 months. More than half of that drop transpired after mid-April 2019.

ETFGI, an industry research and consultancy firm, reported that total assets
invested in exchange-traded funds ("ETFs") and related exchange-traded products
("ETPs") listed globally stood at an all-time high of $5.74 trillion in July
2019, up from $5.12 trillion a year ago, according to its own release. Total
assets of U.S. listed ETFs/ETPs also stood at an all-time high of $4.02 trillion
for the same period, up from $3.63 trillion a year ago.

STYLE/EQUITY INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. The flows are reported over
time on a rolling 12-month basis. For the 12-month period ended July 31, 2019,
U.S. Equity funds/ETFs reported estimated net inflows totaling $40.68 billion,
according to data from Morningstar. As has been the case in recent years,
investors are favoring passive funds over actively managed funds. Passive U.S.
Equity funds/ETFs reported estimated net inflows totaling $242.78 billion,
compared to estimated net outflows totaling $202.10 billion for actively managed
U.S. Equity funds/ETFs for the same period.

For the 12-month period ended July 31, 2019, U.S. Large Blend, U.S. Large Growth
and U.S. Large Value equity funds/ETFs reported estimated net flows totaling
$175.56 billion, -$46.08 billion and -$19.60 billion, respectively, according to
Morningstar. U.S. Mid-Cap Blend, U.S. Mid-Cap Growth and U.S. Mid-Cap Value
equity funds/ETFs reported estimated net flows totaling $11.22 billion, -$8.41
billion and -$14.71 billion, respectively, for the same period. U.S. Small
Blend, U.S. Small Growth and U.S. Small Value equity funds/ETFs reported
estimated net flows totaling $2.75 billion, -$6.11 billion and -$2.45 billion,
respectively, for the same period. Investors were clearly more comfortable
funneling their capital into blended portfolios.

For the 12-month period ended July 31, 2019, the S&P 500(R) Index posted a total
return of 7.99%, according to Bloomberg. Growth stocks outperformed value stocks
in the same period. The S&P 500(R) Growth Index posted a total return of 9.55%,
compared to 6.28% for the S&P 500(R) Value Index for the period. The S&P MidCap
400(R) Index posted a total return of 0.79% in the same period. Growth stocks
outperformed value stocks in the period. The S&P MidCap 400(R) Growth Index
posted a total return of 1.81%, compared to -0.24% for the S&P MidCap 400(R)
Value Index for the same period. The S&P SmallCap 600(R) Index posted a total
return of -6.75% in the period. Growth stocks outperformed value stocks in the
period. The S&P SmallCap 600(R) Growth Index posted a total return of -4.81%,
compared to -8.48% for the S&P SmallCap 600(R) Value Index for the same period.

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

FIRST TRUST LARGE CAP CORE ALPHADEX(R) FUND (FEX)

The First Trust Large Cap Core AlphaDEX(R) 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 AlphaDEX(R) Large Cap Core
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 shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FEX."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 500 Large Cap Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

PERFORMANCE REVIEW

FEX's one-year net asset value ("NAV") return of 3.48% underperformed the S&P
500(R) Index ("Benchmark") return of 7.99% by 4.51%. The Information Technology
sector received the largest allocation and contributed the most to the Fund's
return during the period. This sector carried an average weight of 16.6%,
returned 11.5%, and contributed 1.5% to the Fund's return. The Energy sector,
meanwhile, was the greatest drag on the Fund's return with a 6.1% allocation,
-21.7% performance and -1.9% contribution to the Fund's return. On a relative
basis, the Fund underperformed the Benchmark. The Benchmark over-weighted
Information Technology, in comparison to the Fund, and this well-performing
sector caused -1.4% underperformance for the Fund versus the Benchmark. Some
outperformance for the Fund came from investments in Industrials, which earned
0.4% outperformance versus the Benchmark.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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

FYX's one-year NAV return of -6.52% outperformed the S&P SmallCap 600(R) Index
("Benchmark") return of -6.75% by 0.23%. Investments in Industrials received the
greatest allocation of any sector in the Fund during the period. This sector had
an average weight of 20.5%, returned -6.6%, and contributed -1.1% to the Fund's
total return. The most contributing sector in the Fund were the investments in
Information Technology, which received an allocation of 12.1%, returned 15% and
contributed 1.6% to the Fund's total return. The investments in the Energy
sector were the greatest drag on performance, with a weight of 6.5%, a return of
-53.6%, and a contribution to the Fund's return of -5.2%. On a relative basis,
the Fund outperformed the Benchmark. The greatest contribution to the
outperformance came from investments in the Consumer Discretionary sector. The
Consumer Discretionary investments in the Fund outperformed those in the
Benchmark, resulting in 1.4% outperformance for the Fund. The poorly returning
Energy sector, meanwhile, caused -1.9% underperformance for the Fund, as the
Fund allocated more weight to Energy than did the Benchmark.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 LARGE CAP VALUE ALPHADEX(R) FUND (FTA)

The First Trust Large Cap Value AlphaDEX(R) 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 AlphaDEX(R) Large Cap Value
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 shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FTA."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 500 Large Cap Value Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

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

BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2019

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 1, 2014 through July

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.

performing and contributing sector with a 15.1% return and 0.6% contribution,
stemming from its 6.1% allocation. The Energy sector was the Fund's worst
performing and least contributing sector with a -36.9% return and -3.2%
contribution, stemming from its 7.1% allocation. On a relative basis, the Fund
underperformed the Benchmark. The Fund under-allocated and underperformed the
Benchmark amongst the well-performing Information Technology sector by -5.4% and
-15.5%, respectively, creating -1.9% of relative drag. The Fund over-allocated
the Benchmark among the well-performing Utilities sector by 0.9%, which created
0.1% of relative 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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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.

Growth Index ("Benchmark") return of 8.65% by 4.00%. The Information Technology
sector was the largest allocated and top contributing sector in the Fund over
the period with a 24.5% allocation and 4.7% contribution, stemming from its
20.7% return. The top performing sector in the Fund was the Utilities sector
with a 23.8% return. This sector had a limited 0.4% contribution due to its 2.3%
allocation. The Energy sector, which was only given a 4.8% allocation in the
Fund, was the least contributing and worst performing sector over the period
with a -3.8% contribution and -41.5% return. On a relative basis, the Fund
underperformed the Benchmark. The Fund over weighted the Benchmark among the
poor performing Energy sector by 2.5%, which created -2.9% of relative
underperformance. The Fund outperformed the Benchmark among the Communication

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 MID CAP VALUE ALPHADEX(R) FUND (FNK)

The First Trust Mid Cap Value AlphaDEX(R) 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 AlphaDEX(R) Mid Cap Value
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 shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FNK."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 600 Mid Cap Value Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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 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 JULY 31, 2019

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 1, 2014 through July
31, 2019. 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.

the largest allocation in the Fund over the period. This sector carried a 24.7%
average weight in the Fund, returned -9.2% and contributed -2.8% to the Fund's

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

FIRST TRUST MEGA CAP ALPHADEX(R) FUND (FMK)

The First Trust Mega Cap AlphaDEX(R) 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 AlphaDEX(R) Mega Cap 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
shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the
ticker symbol "FMK."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select mega cap stocks from
the Nasdaq US 500 Large Cap Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

PERFORMANCE REVIEW

FMK's one-year NAV return of 3.24% underperformed the S&P 100(R) Index
("Benchmark") return of 8.34% by 5.10%. The Information Technology sector was
the Fund's heaviest allocated sector over the period with a 19.4% allocation.
However, it was the Communication Services sector that contributed the most to
the Fund over the period with a 3.2% contribution, stemming from its 16.3%
allocation and 20.2% return. The Fund had a relatively smaller allocation to the
Utilities sector with a 3% weighting. This sector was the top performing sector
in the Fund with a 25.8% return. The least performing sector in the Fund was the
Energy sector with a -15.0% return and -1.3% contribution, stemming from its
9.7% allocation. The Fund's least contributing sector was the Consumer Staples
sector with a -1.5% contribution, stemming from its -14.7% return and 9.8%
allocation. On a relative basis, the Fund underperformed the Benchmark. The
primary cause of the underperformance is attributable to the Fund
underperforming the Benchmark among Information Technology securities by -10.2%,
which created -3.7% of relative drag. The Fund outperformed the Benchmark among
Communication Services securities by 11.6%, which created 1.2% of relative
outperformance.

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. For certain Funds 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.

UNDERSTANDING YOUR FUND EXPENSES
JULY 31, 2019 (UNAUDITED)

As a shareholder of First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid
Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First
Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R)
Fund, First Trust Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth
AlphaDEX(R) Fund, First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid
Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First
Trust Small Cap Growth AlphaDEX(R) Fund or First Trust Mega Cap AlphaDEX(R) 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 July 31, 2019.

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.

OFFSETTING ASSETS AND LIABILITIES
-------------------------------------------------------------
Offsetting assets and liabilities requires entities to disclose both gross and
net information about instruments and transactions eligible for offset, and to
disclose instruments and transactions subject to master netting or similar
agreements (see Note 2C - Offsetting on the Statements of Assets and Liabilities
in the Notes to Financial Statements).

The Fund's loaned securities were all subject to an enforceable Securities

Offsetting assets and liabilities requires entities to disclose both gross and
net information about instruments and transactions eligible for offset, and to
disclose instruments and transactions subject to master netting or similar
agreements (see Note 2C - Offsetting on the Statements of Assets and Liabilities
in the Notes to Financial Statements).

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:

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Funds are each considered an investment company and follow accounting and
reporting guidance under Financial Accounting Standards Board ("FASB")
Accounting Standards Codification ("ASC") 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.


                                                                        Page 121

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                                 JULY 31, 2019

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
      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.

                                  STYLE FUNDS
                                 JULY 31, 2019

            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 July 31, 2019, 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
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.

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 fees received from the securities lending agent are accrued daily. The
dividend and interest earned on the securities loaned is accounted for in


                                                                        Page 123

                                  STYLE FUNDS
                                 JULY 31, 2019

the same manner as other dividend and interest income. At July 31, 2019, all the
Funds except FEX, FTA, and FMK had securities in the securities lending program.
During the fiscal year ended July 31, 2019, all the Funds except FMK
participated 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.

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 fiscal year ended July 31, 2019, 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 net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying
treatment of income and gain/loss on significantly modified portfolio securities
held by the Funds and have no impact on net assets or NAV per share. Temporary
differences, which arise from recognizing certain items of income, expense and
gain/loss in different periods for financial statement and tax purposes, will
reverse at some time in the future.

The tax character of distributions paid by each Fund during the fiscal year
ended July 31, 2019, 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 2016, 2017,
2018, and 2019 remain open to federal and state audit. As of July 31, 2019,
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 beginning 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 July 31, 2019, the Funds had 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.


                                                                        Page 125

Certain losses realized during the current fiscal year may be deferred and
treated as occurring the first day of the following fiscal year for federal
income tax purposes. For the fiscal year ended July 31, 2019, the Funds had no
net late year ordinary or capital losses.

In order to present paid-in capital and accumulated distributable earnings
(loss) (which consists of accumulated net investment income (loss), accumulated
net realized gain (loss) on investments and net unrealized appreciation
(depreciation) 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 fiscal
year ended July 31, 2019, the adjustments for each Fund were as follows:

H. EXPENSES

Expenses that are directly related to one of the Funds are charged directly to
the respective Fund, except for the First Trust Mid Cap Value AlphaDEX(R) Fund,
First Trust Mid Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value
AlphaDEX(R) Fund, First Trust Small Cap Growth AlphaDEX(R) Fund and First Trust
Mega Cap AlphaDEX(R) Fund (the "Unitary Fee Funds"), for which expenses other
than excluded expenses (discussed in Note 3) are paid by the Advisor. General
expenses of the Trust are allocated to all the Funds based upon the net assets
of each Fund.

First Trust Portfolios L.P. ("FTP") has entered into licensing agreements with
Nasdaq, Inc. for each of the Style Funds. The license agreements allow for the
use by FTP of certain trademarks and trade names. The Funds and First Trust are
sub-licensees to the applicable license agreement. The Funds, except for the
Unitary Fee Funds, are required to pay licensing fees, which are shown on the
Statements of Operations. The licensing fees for the Unitary Fee Funds are paid
by First Trust from the unitary investment advisory fees it receives from each
of these Funds.

I. NEW ACCOUNTING PRONOUNCEMENT

On August 28, 2018, the FASB issued Accounting Standards Update ("ASU") 2018-13,
"Disclosure Framework - Changes to the Disclosure Requirements for Fair Value
Measurement," which amends the fair value measurement disclosure requirements of
ASC 820. The amendments of ASU 2018-13 include new, eliminated, and modified
disclosure requirements of ASC 820. In addition, the amendments clarify that
materiality is an appropriate consideration of entities when evaluating
disclosure requirements. The ASU is effective for fiscal years beginning after
December 15, 2019, including interim periods therein. Early adoption is
permitted for any eliminated or modified disclosures upon issuance of this ASU.
The Funds have early adopted ASU 2018-13 for these financial statements, which
did not result in a material impact.

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

First Trust, the investment advisor to the Funds, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the selection and ongoing monitoring of the securities
in each Fund's portfolio, managing the Funds' business affairs and providing
certain administrative services necessary for the management of the Funds.

For the Unitary Fee Funds, First Trust is paid an annual unitary management fee
of 0.70% of such Fund's average daily net assets and is responsible for the
expenses of such Fund including the cost of transfer agency, custody, fund
administration, legal, audit, license and other services, and excluding fee
payments under the Investment Management Agreement, distribution and service
fees pursuant to a Rule 12b-1 plan, if any, brokerage expenses, acquired fund
fees and expenses, taxes, interest, and extraordinary expenses.

For the First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core
AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large
Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First
Trust Multi Cap Value AlphaDEX(R) Fund and First Trust Multi Cap Growth
AlphaDEX(R) Fund, First Trust is paid an annual management fee of 0.50% of each
Fund's average daily net assets. For such Funds, the Trust and First Trust 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 each such
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"). These
Funds will have the Expense Cap in effect until at least November 30, 2020.


                                                                        Page 127

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

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.


                                                                        Page 129

                              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 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 November 30, 2020.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

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

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

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
ALPHADEX(R) FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R)
Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value
AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust
Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth AlphaDEX(R) Fund,
First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth
AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust
Small Cap Growth AlphaDEX(R) Fund, and First Trust Mega Cap AlphaDEX(R) Fund
(the "Funds"), each a series of the First Trust Exchange-Traded AlphaDEX(R) Fund
(the "Trust"), including the portfolios of investments, as of July 31, 2019, 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, and
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 twelve portfolios included within the First Trust Exchange-Traded
AlphaDEX(R) Fund as of July 31, 2019, 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 its 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 July 31, 2019, by correspondence with the
custodian and brokers. We believe that our audits provide a reasonable basis for
our opinion.

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                           JULY 31, 2019 (UNAUDITED)

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE
APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS
RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW
APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT
IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY
FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE,
RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF
ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT
WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO
REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND.

CONCENTRATION RISK. To the extent that a fund is able to invest a large
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
not concentrated.

CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable
or unwilling to make dividend, interest and/or principal payments when due and
the related risk that the value of a security may decline because of concerns
about the issuer's ability to make such payments.

CYBER SECURITY RISK. The funds are susceptible to potential operational risks
through breaches in cyber security. A breach in cyber security refers to both
intentional and unintentional events that may cause a fund to lose proprietary
information, suffer data corruption or lose operational capacity. Such events
could cause a fund to incur regulatory penalties, reputational damage,
additional compliance costs associated with corrective measures and/or financial
loss. In addition, cyber security breaches of a fund's third-party service
providers, such as its administrator, transfer agent, custodian, or sub-advisor,
as applicable, or issuers in which the fund invests, can also subject a fund to
many of the same risks associated with direct cyber security breaches.

DERIVATIVES RISK. To the extent a fund uses derivative instruments such as
futures contracts, options contracts and swaps, the fund may experience losses
because of adverse movements in the price or value of the underlying asset,
index or rate, which may be magnified by certain features of the derivative.
These risks are heightened when a fund's portfolio managers use derivatives to
enhance the fund's return or as a substitute for a position or security, rather
than solely to hedge (or offset) the risk of a position or security held by the
fund.

EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the
value of the fund's shares will fluctuate with changes in the value of the
equity securities. Equity securities prices fluctuate for several reasons,
including changes in investors' perceptions of the financial condition of an
issuer or the general condition of the relevant stock market, such as market
volatility, or when political or economic events affecting the issuers occur. In
addition, common stock prices may be particularly sensitive to rising interest
rates, as the cost of capital rises and borrowing costs increase. Equity
securities may decline significantly in price over short or extended periods of
time, and such declines may occur in the equity market as a whole, or they may
occur in only a particular country, company, industry or sector of the market.

ETF RISK. The shares of an ETF trade like common stock and represent an interest
in a portfolio of securities. The risks of owning an ETF generally reflect the
risks of owning the underlying securities, although lack of liquidity in an ETF
could result in it being more volatile and ETFs have management fees that
increase their costs. Shares of an ETF trade on an exchange at market prices
rather than net asset value, which may cause the shares to trade at a price
greater than net asset value (premium) or less than net asset value (discount).
In times of market stress, decisions by market makers to reduce or step away
from their role of providing a market for an ETF's shares, or decisions by an
ETF's authorized participants that they are unable or unwilling to proceed with
creation and/or redemption orders of an ETF's shares, could result in shares of
the ETF trading at a discount to net asset value and in greater than normal
intraday bid-ask spreads.

FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income
securities, the fund will be subject to credit risk, income risk, interest rate
risk, liquidity risk and prepayment risk. Income risk is the risk that income
from a fund's fixed income investments could decline during periods of falling
interest rates. Interest rate risk is the risk that the value of a fund's fixed
income securities will decline because of rising interest rates. Liquidity risk
is the risk that a security cannot be purchased or sold at the time desired, or
cannot be purchased or sold without adversely affecting the price. Prepayment
risk is the risk that the securities will be redeemed or prepaid by the issuer,
resulting in lower interest payments received by the fund. In addition to these
risks, high yield securities, or "junk" bonds, are subject to greater market
fluctuations and risk of loss than securities with higher ratings, and the
market for high yield securities is generally smaller and less liquid than that
for investment grade securities.


                                                                        Page 133

                                  STYLE FUNDS
                           JULY 31, 2019 (UNAUDITED)

INDEX CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. As a result, such a fund may be included in one or more index-tracking
exchange-traded funds or mutual funds. Being a component security of such a
vehicle could greatly affect the trading activity involving a fund, the size of
the fund and the market volatility of the fund. Inclusion in an index could
significantly increase demand for the fund and removal from an index could
result in outsized selling activity in a relatively short period of time. As a
result, a fund's net asset value could be negatively impacted and the fund's
market price may be significantly below its net asset value during certain
periods.

INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject
to Index Provider Risk. There is no assurance that the Index Provider will
compile the Index accurately, or that the Index will be determined, maintained,
constructed, reconstituted, rebalanced, composed, calculated or disseminated
accurately. To correct any such error, the Index Provider may carry out an
unscheduled rebalance or other modification of the Index constituents or
weightings, which may increase the fund's costs. The Index Provider does not
provide any representation or warranty in relation to the quality, accuracy or
completeness of data in the Index, and it does not guarantee that the Index will
be calculated in accordance with its stated methodology. Losses or costs
associated with any Index Provider errors generally will be borne by the fund
and its shareholders.

INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of
other investment vehicles, the fund will incur additional fees and expenses that
would not be present in a direct investment in those investment vehicles.
Furthermore, the fund's investment performance and risks are directly related to
the investment performance and risks of the investment vehicles in which the
fund invests.

MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to
management risk. In managing an actively-managed fund's investment portfolio,
the fund's portfolio managers will apply investment techniques and risk analyses
that may not have the desired result. There can be no guarantee that a fund will
meet its investment objective.

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations.

NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities,
it is subject to additional risks not associated with securities of domestic
issuers. Non-U.S. securities are subject to higher volatility than securities of
domestic issuers due to: possible adverse political, social or economic
developments; restrictions on foreign investment or exchange of securities; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; different legal or accounting standards; and less government supervision
and regulation of exchanges in foreign countries. Investments in non-U.S.
securities may involve higher costs than investments in U.S. securities,
including higher transaction and custody costs, as well as additional taxes
imposed by non-U.S. governments. These risks may be heightened for securities of
companies located, or with significant operations, in emerging market countries.

PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund
will invest in the securities included in, or representative of, the index
regardless of their investment merit. A fund generally will not attempt to take
defensive positions in declining markets.

          NOT FDIC INSURED     NOT BANK GUARANTEED     MAY LOSE VALUE

                                  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 AlphaDEX(R) Fund 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, 2018, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $2,633,004.
This figure is comprised of $115,378 paid (or to be paid) in fixed compensation
and $2,517,626 paid (or to be paid) in variable compensation. There were a total
of 14 beneficiaries of the remuneration described above. Those amounts include
$1,672,097 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $960,907 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").

                           JULY 31, 2019 (UNAUDITED)

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.

                               ADVISORY AGREEMENT

 BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees (the "Board") of First Trust Exchange-Traded AlphaDEX(R)
Fund (the "Trust"), including the Independent Trustees, unanimously approved the
continuation of the Investment Management Agreements (as applicable to a
specific Fund, the "Agreement" and collectively, the "Agreements") with First
Trust Advisors L.P. (the "Advisor") on behalf of the following twelve series of
the Trust (each a "Fund" and collectively, the "Funds"):

        First Trust Large Cap Core AlphaDEX(R) Fund (FEX)
        First Trust Mid Cap Core AlphaDEX(R) Fund (FNX)
        First Trust Small Cap Core AlphaDEX(R) Fund (FYX)
        First Trust Multi Cap Growth AlphaDEX(R) Fund (FAD)
        First Trust Multi Cap Value AlphaDEX(R) Fund (FAB)
        First Trust Large Cap Growth AlphaDEX(R) Fund (FTC)
        First Trust Large Cap Value AlphaDEX(R) Fund (FTA)
        First Trust Mid Cap Growth AlphaDEX(R) Fund (FNY)
        First Trust Mid Cap Value AlphaDEX(R) Fund (FNK)
        First Trust Small Cap Growth AlphaDEX(R) Fund (FYC)
        First Trust Small Cap Value AlphaDEX(R) Fund (FYT)
        First Trust Mega Cap AlphaDEX(R) Fund (FMK)

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2020 at a meeting held on June 2, 2019. The
Board determined for each Fund that the continuation of the Agreement is in the
best interests of the Fund in light of the nature, extent and quality of the
services provided and such other matters as the Board considered to be relevant
in the exercise of its reasonable business judgment.

To reach this determination for each Fund, 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. At meetings held on April 18, 2019 and June 2, 2019, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to the Independent
Trustees, submitted on behalf of the Independent Trustees, that, among other
things, outlined: the services provided by the Advisor to each Fund (including
the relevant personnel responsible for these services and their experience); the


                                                                        Page 135

advisory or unitary fee rate payable by each Fund as compared to fees charged to
a peer group of funds (the "Expense Group") and a broad peer universe of funds
(the "Expense Universe"), each assembled by Broadridge Financial Solutions, Inc.
("Broadridge"), an independent source, and as compared to fees charged to other
clients of the Advisor, including other exchange-traded funds ("ETFs") managed
by the Advisor; the expense ratio of each Fund as compared to expense ratios of
the funds in the Fund's Expense Group and Expense Universe; performance
information for each Fund, including comparisons of each Fund's performance to
that of one or more relevant benchmark indexes and to that of a performance
group of funds and a broad performance universe of funds (the "Performance
Universe"), each assembled by Broadridge; the nature of expenses incurred in
providing services to each 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 Board reviewed initial materials with the Advisor at the
meeting held on April 18, 2019, prior to which the Independent Trustees and
their counsel met separately to discuss the information provided by the Advisor.
Following the April meeting, independent legal counsel on behalf of the
Independent Trustees requested certain clarifications and supplements to the
materials provided, and the information provided in response to those requests
was considered at an executive session of the Independent Trustees and
independent legal counsel held prior to the June 2, 2019 meeting, as well as at
the meeting held that day. The Board applied its business judgment to determine
whether the arrangement between the Trust and the Advisor continues to be a
reasonable business arrangement from each Fund's perspective. The Board
determined that, given the totality of the information provided with respect to
the Agreements, the Board had received sufficient information to renew the
Agreements. The Board considered that shareholders chose to invest or remain
invested in a Fund knowing that the Advisor manages the Fund and knowing the
Fund's advisory or unitary fee.

In reviewing the Agreement for each Fund, the Board considered the nature,
extent and quality of the services provided by the Advisor under the Agreement.
The Board considered that the Advisor is responsible for the overall management
and administration of the Trust and each Fund and reviewed all of the services
provided by the Advisor to the Funds, as well as the background and experience
of the persons responsible for such services. In reviewing the services
provided, the Board noted the compliance program that had been developed by the
Advisor and considered that it includes a robust program for monitoring the
Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's
compliance with its investment objective, policies and restrictions. The Board
also considered a report from the Advisor with respect to its risk management
functions related to the operation of the Funds. Finally, as part of the Board's
consideration of the Advisor's services, the Advisor, in its written materials
and at the April 18, 2019 meeting, described to the Board the scope of its
ongoing investment in additional infrastructure and personnel to maintain and
improve the quality of services provided to the Funds and the other funds in the
First Trust Fund Complex. In light of the information presented and the
considerations made, the Board concluded that the nature, extent and quality of
the services provided to the Trust and each Fund by the Advisor under the
Agreements have been and are expected to remain satisfactory and that the
Advisor has managed each Fund consistent with its investment objective, policies
and restrictions.

For FEX, FNX, FYX, FAD, FAB, FTC and FTA (the "Non-Unitary Fee Funds"), the
Board considered the advisory fee rate payable by each Non-Unitary Fee Fund
under the applicable Agreement for the services provided. The Board considered
that the Advisor agreed to extend the current expense cap for each Non-Unitary
Fee Fund through November 30, 2020. For each Non-Unitary Fee Fund, the Board
noted that expenses borne or fees waived by the Advisor are to be subject to
reimbursement by the Non-Unitary Fee Fund for up to three years from the date
the expense was incurred or fee was waived, but no reimbursement payment would
be made by the Non-Unitary Fee Fund if it would result in the Non-Unitary Fee
Fund exceeding an expense ratio equal to the expense cap in place at the time
the expenses were borne or fees were waived by the Advisor.

For FNY, FNK, FYC, FYT and FMK (the "Unitary Fee Funds"), the Board considered
the unitary fee rate payable by each Unitary Fee Fund under the applicable
Agreement for the services provided. The Board considered that as part of the
unitary fee the Advisor is responsible for each Unitary Fee 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 payment
under the applicable Agreement and 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 showing the advisory or unitary fee
rates and expense ratios of the peer funds in the Expense Groups, as well as
advisory and unitary fee rates charged by the Advisor to other fund (including
ETFs) and non-fund clients, as applicable. Because each Fund's Expense Group
included peer funds that pay a unitary fee and because each Unitary Fee Fund
pays 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 total (net) expense ratio of FTC was below the median total (net)
expense ratio of the peer funds in its Expense Group and that the total (net)
expense ratio of each other Non-Unitary Fee Fund and the unitary fee for each
Unitary Fee Fund were above the median total (net) expense ratio of the peer
funds in each Fund's respective Expense Group. With respect to the Expense
Groups, the Board, at the April 18, 2019 meeting, discussed with Broadridge its
methodology for assembling peer groups and discussed with the Advisor
limitations in creating peer groups for index ETFs, including differences in
underlying indexes and index-tracking methodologies that can result in greater
management complexities across seemingly comparable ETFs, and different business

                           JULY 31, 2019 (UNAUDITED)

models that may affect the pricing of services among ETF sponsors. The Board
took these limitations and differences into account in considering the peer
data. With respect to fees charged to other non-ETF clients, the Board
considered differences between the Funds and other non-ETF clients that limited
their comparability. In considering the advisory and unitary fee rates overall,
the Board also considered the Advisor's statement that it seeks to meet investor
needs through innovative and value-added investment solutions and the Advisor's
description of its long-term commitment to each Fund.

The Board considered performance information for each Fund. The Board noted the
process it has established for monitoring each Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Funds. The Board determined that this process continues to
be effective for reviewing each Fund's performance. The Board received and
reviewed information for periods ended December 31, 2018 regarding the
performance of each Fund's underlying index, the correlation between each Fund's
performance and that of its underlying index, each Fund's tracking difference
and each Fund's excess return as compared to its benchmark index. The Board
noted that, effective April 8, 2016, each Fund changed its underlying index to
an index developed and maintained by Nasdaq, Inc. using the AlphaDEX(R) stock
selection methodology and that the performance information included a blend of
the old and new indexes. The Board considered the Advisor's explanations of how
the AlphaDEX(R) stock selection methodology impacts Fund performance in various
market environments, and the Advisor's statement that AlphaDEX(R) is designed to
provide long-term outperformance. Based on the information provided and its
ongoing review of performance, the Board concluded that each Fund was correlated
to its underlying index and that the tracking difference for each Fund was
within a reasonable range. In addition, the Board reviewed data prepared by
Broadridge comparing each Fund's performance to that of its respective
Performance Universe and to that of a broad-based benchmark index, but given
each Fund's objective of seeking investment results that correspond generally to
the performance of its underlying index, the Board placed more emphasis on its
review of correlation and tracking difference.

On the basis of all the information provided on the fees, expenses and
performance of each Fund and the ongoing oversight by the Board, the Board
concluded that the advisory or unitary fee for each Fund continues to be
reasonable and appropriate in light of the nature, extent and quality of the
services provided by the Advisor to each Fund under the Agreements.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Funds and noted the Advisor's statement that it believes its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Funds. For the Unitary Fee Funds, the Board noted that any
reduction in fixed costs associated with the management of the Unitary Fee Funds
would benefit the Advisor, but that the unitary fee structure provides a level
of certainty in expenses for the Unitary Fee Funds. The Board considered the
revenues and allocated costs (including the allocation methodology) of the
Advisor in serving as investment advisor to each Fund for the twelve months
ended December 31, 2018 and the estimated profitability level for each Fund
calculated by the Advisor based on such data, as well as complex-wide and
product-line profitability data, for the same period. The Board noted the
inherent limitations in the profitability analysis and concluded that, based on
the information provided, the Advisor's profitability level for each Fund was
not unreasonable. In addition, the Board considered fall-out benefits described
by the Advisor that may be realized from its relationship with the Funds. The
Board considered that the Advisor had identified as a fall-out benefit to the
Advisor and FTP their exposure to investors and brokers who, absent their
exposure to the Funds, may have had no dealings with the Advisor or FTP, and
noted that the Advisor does not utilize soft dollars in connection with the
Funds. 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 Agreements continue to be fair and reasonable and that the continuation
of the Agreements is in the best interests of each Fund. No single factor was
determinative in the Board's analysis.

      instructions.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

      (a) Audit Fees (Registrant) -- The aggregate fees billed for each of the
last two fiscal years for professional services rendered by the principal
accountant for the audit of the registrant's annual financial statements or
services that are normally provided by the accountant in connection with
statutory and regulatory filings or engagements were $420,000 for 2018 and
$420,000 for 2019.

      (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 $0 for 2018 and $0 for 2019.

      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
reported under paragraph (a) of this Item were $0 for 2018 and $0 for 2019.

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

      (d) All Other Fees (Registrant) -- The aggregate fees billed in each of

      All Other Fees (Investment Adviser and Distributor) -- The aggregate fees
billed in each of the last two fiscal years for products and services provided
by the principal accountant to the registrant's investment adviser and
distributor, other than the services reported in paragraphs (a) through (c) of

      (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 and
distributor 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:

              Registrant:              Adviser and Distributor:
              -----------              ------------------------
                (b) 0%                          (b) 0%
                (c) 0%                          (c) 0%
                (d) 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 2018 were $45,675
for the registrant, $43,390 for the registrant's investment adviser and $68,710
for the registrant's distributor, and for 2019 were $61,425 for the registrant,
$33,300 for the registrant's investment adviser and $46,000 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.
