                  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

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.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
http://www.ftportfolios.com or speak with your financial advisor. Investment
returns, net asset value and share price will fluctuate and Fund shares, when
sold, may be worth more or less than their original cost.

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

                            HOW TO READ THIS REPORT

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2016

Dear Shareholders:

Thank you for your investment in the Sector Funds of First Trust Exchange-Traded
AlphaDEX(R) Fund.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
annual report which contains detailed information about your investment for the
12 months ended July 31, 2016, including a market overview and a performance
analysis for the period. We encourage you to read this report and discuss it
with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December 2015 had little effect on the money supply, and
the stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and from
February 11, 2016 to July 31, 2016, the S&P 500(R) Index was up 19.99%.

First Trust believes that having a long-term investment horizon and investing in
quality products can help you reach your goals, regardless of how the market
behaves. We have always maintained perspective about the markets and believe
investors should as well. We will continue to strive to provide quality
investment opportunities each and every day, which has been one of the hallmarks
of our firm since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

Sincerely,

/s/ James A. Bowen

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                 ANNUAL REPORT
                                 JULY 31, 2016

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

One of the reasons cited by the Federal Reserve for not raising interest rates
beyond the initial 0.25% hike in the federal funds target rate on December 16,
2015 is the slowdown in global growth. The International Monetary Fund reduced
its global growth estimate for 2016 from 3.3% in April to 3.2% in July. It also
shaved its 2017 estimate by 0.1% to 3.5%, according to its own release. To help
put this concern into perspective, the rate was 5.4% in 2010.

The rebound in the price of crude oil is boosting Mergers & Acquisitions ("M&A")
activity in the energy sector, according to Bloomberg. From February 11, 2016
(multi-year low) through August 25, 2016, the price of a barrel of crude oil
rose 80.6%, from $26.21 to $47.33. Wood Mackenzie, a consulting firm, reported
that more than $11 billion worth of oil and gas transactions were announced
globally in July. It was the highest monthly total so far this year. Since May,
deal volume has totaled $32 billion. Wood Mackenzie believes that M&A activity
will continue to accelerate as oil prices stabilize. Higher energy prices, if
sustained, could help boost global economic growth moving forward. Many nations
around the globe rely fairly heavily on the sale of crude oil to help fund their
economies, in our opinion.

ETFGI, an industry research group, reported that total assets invested in
exchange-traded funds (ETFs) and other exchange-traded products (ETPs) reached a
record high of $3.34 trillion globally in July 2016, according to its own
release. Total assets invested in U.S. ETFs/ETPs reached a record high of $2.37
trillion in July 2016.

SECTOR INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. For the 12-month period
ended July 31, 2016, U.S. Equity funds/ETFs reported net outflows totaling over
$47 billion, according to data from Morningstar. Investors continue to favor
passive funds over actively managed funds. Passive U.S. Equity funds/ETFs
reported net inflows totaling $163.6 billion, compared to net outflows totaling
$211.0 billion for actively managed U.S. Equity funds/ETFs.

For the 12-month period ended July 2016, investors pulled capital from sector
funds/ETFs, which reported net outflows totaling $18.1 billion. Passive Sector
Equity funds/ETFs reported net inflows totaling $3.1 billion, compared to net
outflows totaling $21.2 billion for actively managed Sector Equity funds/ETFs.
Using Morningstar fund categories, some of the major sectors reporting the
highest net inflows over the past 12 months were Real Estate ($7.3 billion),
Equity Energy ($5.6 billion), Utilities ($2.8 billion), Consumer Defensive ($2.3
billion) and Communications ($1.3 billion).

Slow and steady appears to be winning the race, in our opinion. Despite the
moderate pace of economic growth since the previous recession ended in 2009, the
current bull market in stocks is the second-longest in U.S. history at 2,701
days through July, as measured by the S&P 500(R) Index, according to Bespoke
Investment Group. From March 9, 2009 to July 29, 2016, the S&P 500(R) Index
posted a cumulative total return of 275.51%, according Bloomberg. From 2009 to
2015, the S&P 500(R) Index increased its annual earnings from $58.15 to $109.32,
according to Bloomberg. As of August 5, 2016, Bloomberg's consensus estimates
for 2016 and 2017 are $117.73 and $133.11, respectively.


                                                                          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 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 NYSE Group, Inc. or its affiliates ("NYSE") 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) screening methodology. Alpha is an
indication of how much an investment outperforms or underperforms on a
risk-adjusted basis relative to its benchmark. The NYSE constructs the Consumer
Discretionary Index using the Russell Global Sectors (the "RGS") sector scheme
to determine a stock's sector membership.

PERFORMANCE REVIEW

FXD's one-year net asset value ("NAV") return of -2.34% underperformed the
benchmark S&P 500(R) Consumer Discretionary Index return of 3.53% by -5.87%. The
Auto Components industry was the best contributing and best performing industry
during the period, with a 0.97% contribution and 17.4% return. The Textiles
Apparel & Luxury Goods industry was the worst contributing and second worst
performing industry during the period, with a -1.7% contribution and -17.1%
return. The highest weighted industry during the period was Specialty Retail at
an average 23.2% weighting. This industry had an average return of -0.7%. On a
relative basis, the Fund underperformed the benchmark primarily because the Fund
was underweight Amazon.com, Inc. within the Internet & Catalog Retail industry.
Amazon.com, Inc. was held at an average weighting of 1.3% during the period
versus the benchmark weighting of 10.4%. Amazon.com, Inc.'s return of 41.5%
caused -2.9% of relative underperformance. The Fund's underweighting of Walt
Disney Co. by 6.5%, relative to the benchmark, reversed 1.6% of
underperformance. Walt Disney Co. had a return of -18.6% during the period.

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

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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 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
the NYSE 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)
screening methodology. Alpha is an indication of how much an investment
outperforms or underperforms on a risk-adjusted basis relative to its benchmark.
The NYSE 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 9.19% underperformed the benchmark S&P 500(R)
Consumer Staples Index return of 11.67% by -2.48%. With a return of 7.8% and
average weighting of 44.9%, Food Products was the top performing and highest
weighted industry during the period, contributing 7.8% to the Fund's return.
Within the industry, Tyson Foods, Inc. was the top returning security with a
67.6% return. The Food & Staples Retailing was the only industry to have a
negative return during the period, with a -9.6% return. The Fund held this
industry at an average 21.9% weighting, leading to a contribution of -2.0%
during the period. Rite Aid Corp. was the worst performing security with a
-21.4% return. On a relative basis, the Fund underperformed the benchmark
primarily due to the Fund overweighting Rite Aid Corp. by 3.8%, creating -1.5%
of drag, and due to the Fund underweighting the Tobacco industry by 9.7%,
creating -1.2% of drag. The Tobacco industry had a return of 22.7% during the
period. The well-performing Food Products industry reversed 2.3% of drag by
being overweight 27.8% in the well performing industry. Tyson Foods, Inc., as
mentioned above, created 1.8% 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. 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 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 the NYSE
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) screening methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. The NYSE 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 -12.67% underperformed the benchmark S&P 500(R)
Energy Index return of 2.03% by -14.70%. The Energy Equipment & Services and Oil
Gas & Consumable Fuels industries each contributed about -5.75% during the
period. California Resources Corp. stands out as the worst performing security
with a -69.6% return during the period, contributing -2.3% to the Fund's return.
Exxon Mobil Corp. and Chevron Co., the two largest energy conglomerates held
within the Fund, posted solid returns of 16.4% and 21.5%, respectively, during
the period. On a relative basis, the Fund underperformed the benchmark. Exxon
Mobil Corp. and Chevron Co. were two of the leading contributors to the
underperformance as the Fund was underweight the benchmark -25.4% and -11.3%,
respectively, causing in total -5.1% of relative underperformance. Because the
benchmark is market cap weighted, these two securities take the lion's share of
the weighting at 41.6%. The Fund reversed 1.7% of the relative underperformance
by holding Kinder Morgan, Inc., which returned -38.9% during the period, at a 2%
smaller weighting.

(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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

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 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 the
NYSE 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) screening
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. The NYSE
constructs the Financials Index using the RGS sector scheme to determine a
stock's sector membership.

PERFORMANCE REVIEW

FXO's one-year NAV return of 0.22% outperformed the benchmark S&P 500(R)
Financials Index return of -3.77% by 3.99%. It was the Real Estate Investment
Trust ("REIT") industry that contributed the most to the Fund's return during
the period. This industry had a return of 19.9%, an average weighting of 20.8%,
and contribution of 4.4%. Digital Realty Trust, Inc. also stood out as the top
performing security within the REIT industry with a 69.9% return. The Capital
Market industry was the worst contributing industry with a -2.2% contribution.
Notably, Waddell & Reed Financial, Inc. returned -60.9% during the period
creating -0.8% contribution. On a relative basis, the Fund outperformed the
benchmark primarily due to the Fund's holdings within the Banking industry. The
Fund underweighted this poor performing industry (-10.3% return) by 18.6%,
creating 2.5% of relative outperformance. Amongst the Diversified Financial
Services industry, the Fund lost -1.2% of relative performance by having a 7.4%
lower allocation and -7.3% lower return.

(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.

was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July

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

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 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 the
NYSE 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) screening methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. The NYSE constructs the Health
Care 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) 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

Arca under the ticker symbol "FXR."

The Industrials Index is a modified equal-dollar weighted index designed by the
NYSE 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)
screening methodology. Alpha is an indication of how much an investment
outperforms or underperforms on a risk-adjusted basis relative to its benchmark.
The NYSE constructs the Industrials 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) 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.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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
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 the
NYSE 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) screening
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. The NYSE
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 13.48% outperformed the benchmark S&P 500(R)
Materials Index return of 8.40% by 5.08%. Resulting from an 18.8% average
weighting and a 55.8% return, the Metals & Mining industry accounted for 9.2% of
the Fund's return during the period. Several securities posted high returns;
among them was Newmont Mining Co., which returned 157.4% and contributed 3.6% to
the Fund's return. The Chemicals industry, which was given the greatest
allocation during the period at 34.5%, was the worst performing and contributing
industry during the period, with a -1.1% return and -0.4% contribution. On a
relative basis, the Fund outperformed the benchmark. The majority of the
outperformance came from the Metals & Mining industry where the Fund posted a
13.5% higher return than the benchmark and an 8.8% greater allocation, which
created 4.3% of outperformance. The Chemical industry reversed -0.8% of
outperformance by underperforming (-5.5%) and underweighting (-39.7%) 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. 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 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 the
NYSE 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) screening methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. The NYSE constructs the
Technology Index using the RGS sector scheme to determine a stock's sector
membership.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)

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
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 the
NYSE 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) screening methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. The NYSE constructs the
Utilities Index using the RGS sector scheme to determine a stock's sector
membership.

PERFORMANCE REVIEW

FXU's one-year NAV return of 22.66% underperformed the benchmark S&P 500(R)
Utilities Index return of 23.10% by -0.44%. Electric Utilities, with the
greatest allocation of 42.6%, was the top contributing industry with a 10.5%
contribution. The top performing industry, Gas Utilities, had a 48.8% return,
but only contributed 2.9% due to its lower allocation of 5.3% during the period.
The Independent Power & Renewable Electricity Producers industry, with an
allocation of 7.4% during the period, returned -25.5% and contributed -3.1% to
the Fund's return. On a relative basis, the Fund underperformed the benchmark.
The Independent Power & Renewable Electricity Producers industry accounted for
-3.6% of the underperformance due to having a 5.3% greater allocation and -8.9%
worse performance. Calpine Corp. accounted for -2.1% of the drag by the Fund
having a 3.4% greater allocation than the benchmark in the -24.9% returning
security. The Multi-Utilities industry reversed 1.8% of underperformance by
having a 6.5% higher return than the benchmark during the period. SCANA Corp.,
within this industry, was the cause of 0.5% relative outperformance due to the
Fund having a 2.5% greater allocation to the 41.8% returning security.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

NOTES TO FUND PERFORMANCE OVERVIEW
--------------------------------------------------------------------------------

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

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period 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, 2016

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, 2016.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this 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
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the 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
Lending Agency Agreement. Securities lent in accordance with the Securities
Lending Agency Agreement on a gross basis were as follows:

SECURITIES LENDING AGENCY AGREEMENT
-------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(1)    $     4,651,140
Non-cash Collateral(2)                             (4,638,075)
                                              ---------------
Net Amount                                    $        13,065
                                              ===============

(1)   The amount presented on the Statements of Assets and Liabilities, which is
      included in "Investments, at value", is not offset and is shown on a gross
      basis.

(2)   The collateral requirements are determined at the beginning of each
      business day based on the market value of the loaned securities from the
      end of the prior day. On July 29, 2016, the last business day of the
      period, there was sufficient collateral based on the end of day market
      value from the prior business day; however, as a result of market movement
      from July 28 to July 29, the value of the related securities loaned was
      above the collateral value received. See Note 2D - Securities Lending in
      the Notes to Financial Statements.

The Fund's investments in repurchase agreements were all subject to an
enforceable Master Repurchase Agreement. Repurchase Agreements on a gross basis
were as follows:

REPURCHASE AGREEMENTS
-------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(3)    $     2,545,362

(3)   The amount is included in "Investments, at value" on the Statements of
      Assets and Liabilities.

(4)   At July 31, 2016, the value of the collateral received from each seller
      exceeded the value of the repurchase agreements.

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
Lending Agency Agreement. Securities lent in accordance with the Securities
Lending Agency Agreement on a gross basis were as follows:

SECURITIES LENDING AGENCY AGREEMENT
-------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(1)    $     3,786,475
Non-cash Collateral(2)                             (3,624,900)
                                              ---------------
Net Amount                                    $       161,575
                                              ===============

(1)   The amount presented on the Statements of Assets and Liabilities, which is
      included in "Investments, at value", is not offset and is shown on a gross
      basis.

(2)   The collateral requirements are determined at the beginning of each
      business day based on the market value of the loaned securities from the
      end of the prior day. On July 29, 2016, the last business day of the
      period, there was sufficient collateral based on the end of day market
      value from the prior business day; however, as a result of market movement
      from July 28 to July 29, the value of the related securities loaned was
      above the collateral value received. See Note 2D - Securities Lending in
      the Notes to Financial Statements.

The Fund's investments in repurchase agreements were all subject to an
enforceable Master Repurchase Agreement. Repurchase Agreements on a gross basis
were as follows:

REPURCHASE AGREEMENTS
-------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(3)    $     1,989,334
Non-cash Collateral(4)                             (1,989,334)

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

(3)   The amount is included in "Investments, at value" on the Statements of
      Assets and Liabilities.

(4)   At July 31, 2016, the value of the collateral received from each seller
      exceeded the value of the repurchase agreements.

                                  SECTOR FUNDS
                                 JULY 31, 2016

                                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." Creation Units are issued and redeemed principally in-kind
for securities included in a Fund's relevant index. 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

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Funds, each of which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follow
accounting and reporting guidance under FASB Accounting Standards Codification
Topic 946, "Financial Services-Investment Companies." The following is a summary
of significant accounting policies consistently followed by the Funds in the
preparation of the financial statements. The preparation of the financial
statements in accordance with accounting principles generally accepted in the
United States of America ("U.S. GAAP") requires management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION

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

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


                                                                         Page 61

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2016

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 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 pricing service, does not reflect the security's fair value. As a general
principle, the current fair value of a security would appear to be the amount
which the owner might reasonably expect to receive for the security upon its
current sale. When fair value prices are used, generally they will differ from
market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

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

      6)    relationships among various securities;

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

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

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

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, 2016

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, 2016, 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.

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 dividend and interest earned on the securities loaned is accounted for in
the same manner as other dividend and interest income. At July 31, 2016, all the
Funds except FXH, FXR and FXZ have securities in the securities lending program.
During the fiscal year ended July 31, 2016, 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 Funds 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 63

                                 JULY 31, 2016

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 Notes. The U.S. Treasury Notes 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 Notes 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 is 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, 2016, were received as
collateral for lending securities.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

Distributions from income and capital gains are determined in accordance with
income tax regulations, which may differ from U.S. GAAP. Certain capital
accounts in the financial statements are periodically adjusted for permanent
differences in order to reflect their tax character. These permanent differences
are primarily due to the varying treatment of income and gain/loss on
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, 2016 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 the 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 2013, 2014,
2015 and 2016 remain open to federal and state audit. As of July 31, 2016,
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, 2016, the Funds had pre-enactment
and post-enactment net capital losses for federal income tax purposes as shown
in the following table. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to Fund shareholders. The Funds are subject to certain
limitations, under U.S. tax rules, on the use of capital loss carryforwards and
net unrealized built-in losses. These limitations apply when there has been a
50% change in ownership.

At the taxable year ended July 31, 2016, the following Funds' capital loss
carryforwards expired in the following amounts:

In order to present paid-in capital, accumulated net investment income (loss)
and accumulated net realized gain (loss) on investments on the Statements of
Assets and Liabilities that more closely represent their tax character, certain
adjustments have been made to paid-in capital, accumulated net investment income
(loss) and accumulated net realized gain (loss) on investments. These
adjustments are primarily due to the difference between book and tax treatments
of income and gains on various investment securities held by the Funds and
in-kind transactions. The results of operations and net assets were not affected
by these adjustments. For the fiscal year ended July 31, 2016, 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 Archipelago for each of the
Funds. The license agreements allow for the use by FTP of certain trademarks and
trade names of Archipelago and certain trademarks and trade names of NYSE Group.
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.

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, 2017.

                                 JULY 31, 2016

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 an expense ratio equal to the Expense Cap in
place at the time the expenses were reimbursed or fees waived by First Trust.
These amounts would be included in "Expenses previously waived or reimbursed" on
the Statements of Operations.

For the fiscal year ended July 31, 2016 there were no fees waived or expenses
reimbursed by First Trust for the Funds. As of July 31, 2016, none of the Funds
had remaining fees previously waived or expenses reimbursed that were still
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.

At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark
Bradley's resignation from his position as the President and Chief Executive
Officer of the Trust, effective December 31, 2015. At the same meeting, the
Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and
Treasurer of the Trust, to serve as the President and Chief Executive Officer,
and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as
the Treasurer, Chief Financial Officer and Chief Accounting Officer of the
Trust.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. Each Independent Trustee is also paid an
annual per fund fee that varies based on whether the fund is a closed-end or
other actively managed fund or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
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, 2016

                  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 June 30, 2017.

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

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, each a series of the First Trust Exchange-Traded
AlphaDEX(R) Fund (the "Funds"), including the portfolios of investments, as of
July 31, 2016, and 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. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Funds
are not required to have, nor were we engaged to perform, an audit of their
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of July 31, 2016 by correspondence with the Funds'
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.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the funds listed above included in the First Trust Exchange-Traded
AlphaDEX(R) Fund as of July 31, 2016, 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.

                              RISK CONSIDERATIONS

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

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

CONSUMER DISCRETIONARY COMPANIES RISK. Certain of the Funds invest in consumer
discretionary companies. Consumer discretionary companies are companies that
provide non-essential goods and services, such as retailers, media companies and
consumer services. These companies manufacture products and provide
discretionary services directly to the consumer, and the success of these
companies is tied closely to the performance of the overall domestic and

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                           JULY 31, 2016 (UNAUDITED)

international economy, interest rates, competition and consumer confidence.
Success depends heavily on disposable household income and consumer spending.
Changes in demographics and consumer tastes can also affect the demand for, and
success of, consumer discretionary products in the marketplace.

CONSUMER STAPLES COMPANIES RISK. Certain of the Funds invest in consumer staples
companies. Consumer staples companies provide products directly to the consumer
that are typically considered non-discretionary items based on consumer
purchasing habits. The success of these companies is affected by a variety of
factors, such as government regulations, which may affect the permissibility of
using various food additives and the production methods of companies that
manufacture food products.

ENERGY COMPANIES RISK. Certain of the Funds invest in energy companies. Energy
companies include integrated oil companies that are involved in the exploration,
production and refining process, gas distributors and pipeline-related companies
and other energy companies involved with mining, producing and delivering
energy-related services and drilling. General problems of energy companies
include volatile fluctuations in price and supply of energy fuels, international
politics, terrorist attacks, reduced demand, the success of exploration
projects, clean-up and litigation costs relating to oil spills and environmental
damage, and tax and other regulatory policies of various governments. Natural
disasters such as hurricanes in the Gulf of Mexico also impact the petroleum
industry. Oil production and refining companies are subject to extensive
federal, state and local environmental laws and regulations regarding air
emissions and the disposal of hazardous materials. In addition, oil prices are
generally subject to extreme volatility.

EQUITY SECURITIES RISK. Because the Funds invest in equity securities, the value
of the Funds' shares will fluctuate with changes in the value of these equity
securities. Equity securities prices fluctuate for several reasons, including
changes in investors' perceptions of the financial condition of an issuer or the
general condition of the relevant stock market, such as market volatility, or
when political or economic events affecting the issuers occur. In addition,
common stock prices may be particularly sensitive to rising interest rates, as
the cost of capital rises and borrowing costs increase.

FINANCIAL COMPANIES RISK. Certain of the Funds invest in financial companies.
Financial companies are especially subject to the adverse effects of economic
recession, currency exchange rates, government regulation, decreases in the
availability of capital, volatile interest rates, portfolio concentrations in
geographic markets and in commercial and residential real estate loans, and
competition from new entrants in their fields of business.

GROWTH STOCKS INVESTMENT RISK. Growth stocks tend to be more volatile than
certain other types of stocks and their prices usually fluctuate more
dramatically than the overall stock market. A stock with growth characteristics
can have sharp price declines due to decreases in current or expected earnings.

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

INDEX CONSTITUENT RISK. One or more of the Funds may be a constituent of one or
more indices. As a result, the Fund may be included in one or more
index-tracking ETFs or mutual funds. Being a component security of such a
vehicle could greatly affect the trading activity involving the 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, the Fund's NAV could be negatively impacted and the Fund's market price
may be significantly below the Fund's net asset value during certain periods In
addition, index rebalances may potentially result in increased trading activity.
To the extent buying or selling activity increases, the Fund can be exposed to
increased brokerage costs and adverse tax consequences and the market price of
the Fund can be negatively affected.

INDUSTRIALS COMPANIES RISK. Certain of the Funds invest in industrials
companies. Industrials companies convert unfinished goods into finished durables
used to manufacture other goods or provide services. Some industrials companies
are involved in electrical equipment and components, industrial products,
manufactured housing and telecommunications equipment. General risks of
industrials companies include the general state of the economy, intense
competition, consolidation, domestic and international politics, excess capacity
and consumer demand and spending trends. In addition, they may also be
significantly affected by overall capital spending levels, economic cycles,
technical obsolescence, delays in modernization, labor relations, government
regulations and e-commerce initiatives.


                                                                         Page 71

                           JULY 31, 2016 (UNAUDITED)

INFORMATION TECHNOLOGY COMPANIES RISK. Certain of the Funds invest in
information technology companies. Information technology companies are generally
subject to the following risks: rapidly changing technologies; short product
life cycles; fierce competition; aggressive pricing and reduced profit margins;
the loss of patent, copyright and trademark protections; cyclical market
patterns; evolving industry standards; and frequent new product introductions.
Information technology companies may be smaller and less experienced companies,
with limited product lines, markets or financial resources and fewer experienced
management or marketing personnel. Information technology company stocks,
especially those which are Internet related, have experienced extreme price and
volume fluctuations that are often unrelated to their operating performance.

MARKET RISK. Market risk is the risk that a particular security owned by a Fund
or shares of a Fund in general may fall in value. Securities are subject to
market fluctuations caused by such factors as economic, political, regulatory or
market developments, changes in interest rates and perceived trends in
securities prices. Shares of the Funds could decline in value or underperform
other investments.

MATERIALS AND PROCESSING COMPANIES RISK. Certain of the Funds invest in
materials and processing companies. General risks of the materials sector
include the general state of the economy, consolidation, domestic and
international politics and excess capacity. In addition, basic materials
companies may also be significantly affected by volatility of commodity prices,
import controls, worldwide competition, liability for environmental damage,
depletion of resources and mandated expenditures for safety and pollution
control devices.

NON-CORRELATION RISK. A Fund's return may not match the return of its Index for
a number of reasons. For example, a Fund incurs operating expenses not
applicable to its Index, and may incur costs in buying and selling securities,
especially when rebalancing the Fund's portfolio holdings to reflect changes in
the composition of the Index. In addition, a Fund's portfolio holdings may not
exactly replicate the securities included in its Index or the ratios between the
securities included in the Index.

PORTFOLIO TURNOVER RISK. Certain Funds' strategies may frequently involve buying
and selling portfolio securities to rebalance the Funds' exposure to various
market sectors. High portfolio turnover may result in a Fund paying higher
levels of transaction costs and generating greater tax liabilities for
shareholders. Portfolio turnover risk may cause a Fund's performance to be less
than you expect.

REPLICATION MANAGEMENT RISK. The Funds are exposed to additional market risk due
to their policy of investing principally in the securities included in the
Indices. As a result of this policy, securities held by the Funds will generally
not be bought or sold in response to market fluctuations.

SMALLER COMPANIES RISK. Small and/or mid capitalization companies may be more
vulnerable to adverse general market or economic developments, and their
securities may be less liquid and may experience greater price volatility than
larger, more established companies as a result of several factors, including
limited trading volumes, products or financial resources, management
inexperience and less publicly available information. Accordingly, such
companies are generally subject to greater market risk than larger, more
established companies.

TELECOMMUNICATIONS COMPANIES RISK. Certain of the Funds invest in
telecommunications companies. Telecommunications companies are subject to risks,
which include increased competition and regulation by various regulatory
authorities, the need to commit substantial capital and technological
obsolescence.

UTILITIES COMPANIES RISK. Certain of the Funds invest in utilities companies.
General problems of utilities companies include the imposition of rate caps,
increased competition due to deregulation, the difficulty in obtaining an
adequate return on invested capital or in financing large construction projects,
the limitations on operations and increased costs and delays attributable to
environmental considerations and the capital market's ability to absorb utility
debt. In addition, taxes, government regulation, international politics, price
and supply fluctuations, volatile interest rates and energy conservation may
cause difficulties for utilities. All of such issuers have been experiencing
certain of these problems in varying degrees.

VALUE STOCKS INVESTMENT RISK. The intrinsic value of a stock with value
characteristics may not be fully recognized by the market for a long time or a
stock judged to be undervalued may actually be appropriately priced at a low
level.

First Trust Exchange-Traded AlphaDEX(R) Fund it manages (the "Funds") in the
United Kingdom 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, 2015, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $9,067,727.
This figure is comprised of $453,849 paid (or to be paid) in fixed compensation
and $8,613,878 paid (or to be paid) in variable compensation. There were a total
of 13 beneficiaries of the remuneration described above. Those amounts include
$5,011,396 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $4,056,331 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 the First Trust Exchange-Traded

approved the continuation of the Investment Management Agreement (the
"Agreement") with First Trust Advisors L.P. (the "Advisor" or "First Trust") 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 Materials AlphaDEX(R) Fund (FXZ)

                                                                         Page 73

ADDITIONAL INFORMATION (CONTINUED)

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                           JULY 31, 2016 (UNAUDITED)

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2017 at a meeting held on June 13, 2016. The
Board determined for each Fund that the continuation of the Agreement is in the
best interests of the Fund in light of the extent and quality of the services
provided and such other matters as the Board considered to be relevant in the
exercise of its reasonable business judgment.

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 22, 2016 and June 13, 2016, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to 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 (all of which were exchange-traded funds
("ETFs")) compiled by Management Practice, Inc. ("MPI"), an independent source
(the "MPI Peer Group"), and as compared to fees charged to other clients of the
Advisor, including other ETFs managed by the Advisor; expenses of each Fund as
compared to expense ratios of the funds in the Fund's MPI Peer Group;
performance information for each Fund; 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 a
special meeting held on April 22, 2016, 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 13, 2016 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 as well as from the
perspective of shareholders. 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 and policies. In addition, as part of
the Board's consideration of the Advisor's services, the Advisor, in its written
materials and at the April 22, 2016 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 the Fund's investment objective and
policies.

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,
2017. 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 MPI Peer Groups, as well as advisory fee and unitary fee rates
charged by the Advisor to other fund (including ETFs) and non-fund clients.
Because each Fund's MPI Peer 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 each Fund's respective MPI Peer Group. With respect to the MPI
Peer Groups, the Board discussed with representatives of 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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                           JULY 31, 2016 (UNAUDITED)

respect to fees charged to other clients, the Board considered differences
between the Funds and other 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, 2015 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 consistent with the
Fund's prospectus. In addition, the Board reviewed data prepared by MPI
comparing each Fund's performance to its respective MPI Peer Group and to one or
more broad-based benchmark indexes, 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 expects its expenses to
increase over the next twelve months as the Advisor continues to make
investments in personnel and infrastructure. 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, 2015 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.
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 its
management of the Funds' portfolios.

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

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

                            HOW TO READ THIS REPORT

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

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

It is important to keep in mind that the opinions expressed by personnel of the
Advisor are just that: informed opinions. They should not be considered to be
promises or advice. The opinions, like the statistics, cover the period through
the date on the cover of this report. The material risks of investing in each
Fund are spelled out in its prospectus, statement of additional information,
this report and other Fund regulatory filings.

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2016

Dear Shareholders:

Thank you for your investment in the Style Funds of First Trust Exchange-Traded
AlphaDEX(R) Fund.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
annual report which contains detailed information about your investment for the
12 months ended July 31, 2016, including a market overview and a performance
analysis for the period. We encourage you to read this report and discuss it
with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December 2015 had little effect on the money supply, and
the stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and from
February 11, 2016 to July 31, 2016, the S&P 500(R) Index was up 19.99%.

First Trust believes that having a long-term investment horizon and investing in
quality products can help you reach your goals, regardless of how the market
behaves. We have always maintained perspective about the markets and believe
investors should as well. We will continue to strive to provide quality
investment opportunities each and every day, which has been one of the hallmarks
of our firm since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

Sincerely,

/s/ James A. Bowen

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

                                 ANNUAL REPORT
                                 JULY 31, 2016

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./GLOBAL ECONOMY

One of the reasons cited by the Federal Reserve for not raising interest rates
beyond the initial 0.25% hike in the federal funds target rate on December 16,
2015 is the slowdown in global growth. The International Monetary Fund reduced
its global growth estimate for 2016 from 3.3% in April to 3.2% in July. It also
shaved its 2017 estimate by 0.1% to 3.5%, according to its own release. To help
put this concern into perspective, the rate was 5.4% in 2010.

The rebound in the price of crude oil is boosting Mergers & Acquisitions ("M&A")
activity in the energy sector, according to Bloomberg. From February 11, 2016
(multi-year low) through August 25, 2016, the price of a barrel of crude oil
rose 80.6%, from $26.21 to $47.33. Wood Mackenzie, a consulting firm, reported
that more than $11 billion worth of oil and gas transactions were announced
globally in July. It was the highest monthly total so far this year. Since May,
deal volume has totaled $32 billion. Wood Mackenzie believes that M&A activity
will continue to accelerate as oil prices stabilize. Higher energy prices, if
sustained, could help boost global economic growth moving forward. Many nations
around the globe rely fairly heavily on the sale of crude oil to help fund their
economies, in our opinion.

ETFGI, an industry research group, reported that total assets invested in
exchange-traded funds (ETFs) and other exchange-traded products (ETPs) reached a
record high of $3.34 trillion globally in July 2016, according to its own
release. Total assets invested in U.S. ETFs/ETPs reached a record high of $2.37
trillion in July 2016.

STYLE/MARKET CAP INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. For the 12-month period
ended July 31, 2016, U.S. Equity funds/ETFs reported net outflows totaling over
$47 billion, according to data from Morningstar. Investors continue to favor
passive funds over actively managed funds. Passive U.S. Equity funds/ETFs
reported net inflows totaling $163.6 billion, compared to net outflows totaling
$211.0 billion for actively managed U.S. Equity funds/ETFs.

For the 12-month period ended July 2016, Morningstar reported the following net
flows for these nine Style/Market Cap fund categories: $51.2 billion (Large
Blend); $1.1 billion (Large Value); -$58.8 billion (Large Growth); -$2.2 billion
(Mid-Cap Blend); -$6.4 billion (Mid-Cap Value); -$20.3 billion (Mid-Cap Growth);
-$0.4 billion (Small Blend); $2.6 billion (Small Value); and -$14.4 billion
(Small Growth).

Slow and steady appears to be winning the race, in our opinion. Despite the
moderate pace of economic growth since the previous recession ended in 2009, the
current bull market in stocks is the second-longest in U.S. history at 2,701
days through July, as measured by the S&P 500(R) Index, according to Bespoke
Investment Group. From March 9, 2009 to July 29, 2016, the S&P 500(R) Index
posted a cumulative total return of 275.51%, according Bloomberg. From 2009 to
2015, the S&P 500(R) Index increased its annual earnings from $58.15 to $109.32,
according to Bloomberg. Currently, Bloomberg's consensus estimates for 2016 and
2017 are $117.73 and $133.11, respectively.


                                                                          Page 3

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

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

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Large Cap Core AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Large Cap Core Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an 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 in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FEX." The Fund
commenced trading on May 9, 2007.

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.

(1)   The Defined Large Cap Core Index was replaced with the Nasdaq AlphaDEX(R)
      Large Cap Core Index. The new index is substantially similar to the old
      index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns from April 8, 2016 through July 31,
      2016 were 7.33% and 7.38% at NAV and Market Price, respectively. That
      compares to an Index return of 7.54% for the same period.

PERFORMANCE REVIEW

FEX's one-year net asset value ("NAV") return of 3.59% underperformed the
benchmark S&P 500(R) Index return of 5.61% by -2.02%. The Utilities sector was
the leading contributing sector during the period with a 1.9% contribution,
24.2% return, and 8.4% average weighting. The Gas Utilities industry had an
impressive 51.9% return, but was limited to a 0.2% contribution due to its small
allocation of 0.4%. The Consumer Discretionary sector was given the highest
weighting during the period at 19%, and due to its -3.6% return, contributed
-1.1% to the Fund's return. Amongst the Consumer Discretionary sector,
securities held within the Multiline Retail industry such as Kohls Co., Macy's
Inc., and Nordstrom, Inc. had a -21.9% return and contributed -0.4% to the
Fund's return. On a relative basis the Fund underperformed the benchmark
primarily due to the Consumer Discretionary sector where the Fund was overweight
the sector by 6.2% and underperformed by -7.1%, creating -1.7% of relative
underperformance. The Financials sector, the second highest weighted sector
during the period at 15.2%, reversed 1.3% of underperformance by outperforming
the benchmark by 4.9%.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST MID CAP CORE ALPHADEX(R) FUND (FNX)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Mid Cap Core AlphaDEX(R) Fund (the "Fund") sought investment results
that corresponded generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the Defined Mid Cap Core Index. Effective
April 8, 2016, the Fund changed its investment objective to seek investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Nasdaq AlphaDEX(R) Mid Cap Core
Index (the "Index"). The Fund will normally invest at least 90% of its net
assets in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FNX." The Fund
commenced trading on May 9, 2007.

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 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

FNX's one-year NAV return of 0.76% underperformed the benchmark S&P MidCap
400(R) Index return of 5.53% by -4.77%. The Financials sector contributed the
most during the period to the Fund's return, with a 2.5% contribution stemming
from its high 21.8% allocation and 6.6% return. Amongst this sector, the Real
Estate Investment Trust ("REIT") industry contributed 2.8% to the Fund's return.
REITs had a return of 29.8% during the period. The Energy sector was the Fund's
worst performing sector with a -29.3% return, contributing -3.1% to the Fund's
return, and given an average allocation of 6.4% during the period. The two
industries within the Energy sector, the Oil Gas & Consumable Fuels and the
Energy Equipment & Services contributed -1.9% and -1.2%, respectively, to the
Fund's return. On a relative basis the Fund underperformed the benchmark. The
Energy sector caused -1.4% of the underperformance by allocating 2.8% more of
the Fund's weighting to the -29.3% returning sector. Several securities
contributed to this sectors underperformance including Atwood Oceanics, Inc.
(-0.40%), SM Energy Co. (-0.30%), and Western Refining, Inc. (-0.20%). The
Utilities sector, which was the top returning sector during the period at 31.0%,
reversed 0.6% of underperformance as the Fund was slightly overweight the
benchmark by 0.6%. Most securities held within the sector contributed to the
outperformance as they were given slightly higher allocations than 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 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST SMALL CAP CORE ALPHADEX(R) FUND (FYX)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Small Cap Core AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Small Cap Core Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Small
Cap Core Index (the "Index"). The Fund will normally invest at least 90% of its
net assets in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FYX." The Fund
commenced trading on May 9, 2007.

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 700 Small 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.

(1)   The Defined Small Cap Core Index was replaced with the Nasdaq AlphaDEX(R)
      Small Cap Core Index. The new index is substantially similar to the old
      index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 12.13% and 12.33% at NAV and Market Price,
      respectively. That compares to an Index return of 12.33% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FYX's one-year NAV return of 2.20% underperformed the benchmark S&P SmallCap
600(R) Index return of 5.96% by -3.76%. The Information Technology sector
contributed the most to the Fund's return during the period with a 2.8%
contribution. This sector had a 16.2% allocation and 19.5% return. Within the
Information Technology sector, the Diversified Telecommunication Services
industry had an impressive 57.9% return. The Energy sector contributed -3.8% to
the Fund's return as a result of the Fund allocating 4.9% to the -37.8%
returning sector. The Energy Equipment & Services industry, in particular,
returned -46.7% and contributed -2.3% to the Fund's return. On a relative basis
the Fund underperformed the benchmark primarily due to the Energy sector. This
sector had a -7.5% lower return during the period and was given a 2.0% greater
allocation. It was the Energy Equipment & Services industry that created the
most underperformance within the Energy sector, creating -1.6% drag from its
-19.1% lower return, relative to the benchmark. The Financials and Information
Technology sectors each reversed about 0.34% of drag by outperforming 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 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. 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)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Large Cap Value AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Large Cap Value Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an 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 in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FTA." The Fund
commenced trading on May 9, 2007.

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.

(1)   The Defined Large Cap Value Index was replaced with the Nasdaq AlphaDEX(R)
      Large Cap Value Index. The new index is substantially similar to the old
      index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 6.78% and 6.74% at NAV and Market Price,
      respectively. That compares to an Index return of 6.99% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FTA's one-year NAV return of 2.94% underperformed the benchmark S&P 500(R) Value
Index return of 5.79% by -2.85%. The Energy sector contributed -1.9% to the
Fund's return during the period as it had a -9.8% return and 12.3% allocation.
The Oil Gas & Consumables industry contributed -1.2% of the -1.9% due to the
fact that the Fund had a return of -8.6% and 9.5% allocation within the
industry. The Utilities sector was by far the leading sector in terms of
contribution. The Utilities sector contributed 2.9% as a result of the Fund's
23.5% return and 13.5% allocation. The Multi-Utilities and Electric Utilities
industries each accounted for about 1.5% of contribution. On a relative basis,
the Fund underperformed the benchmark. The Energy sector accounted for -2.3% of
the underperformance due to the Fund having a -17.1% worse relative return.
Several securities contributed to the sectors underperformance, including
Southwestern Energy Co. (-0.4% of underperformance), Exxon Mobil Corp. (-0.38%),
and HollyFrontier Co., (-0.28%). The Financials sector reversed close to 2.1% of
underperformance within the Banking industry by underweighting the benchmark by
5.3% and outperforming the benchmark by 1.8%. Wells Fargo & Co., Citigroup Inc.,
and Bank of America Co. were the three largest contributors to the
outperformance, each creating about 0.5% 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST LARGE CAP GROWTH ALPHADEX(R) FUND (FTC)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Large Cap Growth AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Large Cap Growth Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Large
Cap Growth Index (the "Index"). The Fund will normally invest at least 90% of
its net assets in common stocks that comprise the Index. From the beginning of
the period covered by this report until April 8, 2016, the shares of the Fund
traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are
listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FTC."
The Fund commenced trading on May 9, 2007.

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 Growth 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.

(1)   The Defined Large Cap Growth Index was replaced with the Nasdaq
      AlphaDEX(R) Large Cap Growth Index. The new index is substantially similar
      to the old index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 7.26% and 7.31% at NAV and Market Price,
      respectively. That compares to an Index return of 7.47% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FTC's one-year NAV return of 3.96% underperformed the benchmark S&P 500(R)
Growth Index return of 5.28% by -1.32%. The Information Technology sector was
the leading contributing sector with a 2.1% contribution. This sector was given
the second highest weighting of 18.8% and had a return of 10.8%. NVIDIA Corp.
notably had 190.3% return during the period and contributed 1.0%. The Health
Care sector, the third highest weighted sector at 15.7%, was the worst
contributing sector with a return of -1.8%, causing a -2.3% contribution. The
Health Care Providers & Services industry contributed -1.3%, containing
securities such as Tenet Healthcare Co. (-32.1% return), HCA Holdings, Inc.
(-32.4% return), and AmerisourceBergen Co. (-17.2% return). On a relative basis,
the Fund underperformed the benchmark primarily due to the Fund having a 4.6%
greater allocation and -6.2% lower relative return within the Consumer
Discretionary sector, causing -1.7% of underperformance. Amazon.com, Inc., held
within the Consumer Discretionary sector, was held at a 1.6% lower weighting
relative to the benchmark throughout the period, which created -0.5% of
underperformance. The Energy sector, which made up a small portion of the Fund
throughout the period at 0.7%, reversed 0.9% of underperformance by having a
notable 36.6% higher return than the benchmark. Cameron International Co.,
within the Energy sector, in particular, had a 38.4% higher return than 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 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST MULTI CAP VALUE ALPHADEX(R) FUND (FAB)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Multi Cap Value AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Multi Cap Value Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Multi
Cap Value Index (the "Index"). The Fund will normally invest at least 90% of its
net assets in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FAB." The Fund
commenced trading on May 9, 2007.

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select value stocks from the
Nasdaq US 500 Large Cap Index, Nasdaq US 600 Mid Cap Index and Nasdaq US 700
Small Cap Index (together the "Nasdaq US Multi 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.

(1)   The Defined Multi Cap Value Index was replaced with the Nasdaq AlphaDEX(R)
      Multi Cap Value Index. The new index is substantially similar to the old
      index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 8.04% and 8.31% at NAV and Market Price,
      respectively. That compares to an Index return of 8.28% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FAB's one-year NAV return of 1.98% underperformed the benchmark S&P Composite
1500(R) Value Index return of 6.03% by -4.05%. The Utilities sector contributed
the most to the Fund's return, with a 2.5% contribution, coming from the
sector's 27.7% return and 10.0% allocation. Electric Utilities were the cause of
1.2% of the Fund's return. This industry had a 5.3% allocation and 25.3% return.
The Energy sector contributed -3.9% to the Fund's return as it returned -21.9%
and was given an allocation of 11%. On a relative basis, the Fund underperformed
the benchmark. The Energy sector contributed the most to the relative
underperformance. The Fund and benchmark each had an allocation of about 11%,
but the Fund had a -26.8% lower return than the benchmark. The return difference
is attributable to the Energy Equipment & Services and Oil Gas & Consumable
Fuels industries, having -20.4% and -26.8% lower returns than the benchmark,
respectively. The Financials sector reversed 2.6% of underperformance as the
Fund was underweight the benchmark in this relatively poor performing sector
(0.4% return) by 4.9%. The Banking industry, in particular, was the cause of
1.9% of the outperformance as the Fund underweighted the benchmark by 5.3% and
outperformed the benchmark by 6.9%.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST MULTI CAP GROWTH ALPHADEX(R) FUND (FAD)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Multi Cap Growth AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Multi Cap Growth Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Multi
Cap Growth Index (the "Index"). The Fund will normally invest at least 90% of
its net assets in common stocks that comprise the Index. From the beginning of
the period covered by this report until April 8, 2016, the shares of the Fund
traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are
listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FAD."
The Fund commenced trading on May 9, 2007.

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select growth stocks from
the Nasdaq US 500 Large Cap Index, Nasdaq US 600 Mid Cap Index and Nasdaq US 700
Small Cap Index (together the "Nasdaq US Multi Cap Growth 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.

(1)   The Defined Multi Cap Growth Index was replaced with the Nasdaq
      AlphaDEX(R) Multi Cap Growth Index. The new index is substantially similar
      to the old index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 8.67% and 8.89% at NAV and Market Price,
      respectively. That compares to an Index return of 8.91% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FAD's one-year NAV return of 2.66% underperformed the benchmark S&P Composite
1500(R) Growth Index return of 5.06% by -2.40%. The Financials sector
contributed the most to the Fund's return with a 2.3% contribution. This sector
had a 9.1% return and was given the third highest allocation amongst the various
sectors at 16.1%. The REIT industry, in particular, contributed 2.8% to the
Fund's return due to its 32.5% return and 7.6% allocation. The Health Care
sector posted the worst return during the period at -4.2%, and due to its high
allocation of 16.3%, the sector contributed -2.1% to the Fund's return. The
Pharmaceuticals industry in particular had a -28.2% return and -1.1% relative
contribution. On a relative basis, the Fund underperformed the benchmark
primarily due to the Consumer Discretionary sector. Within this sector, -1.8% of
drag was created by having a 1.9% higher weighting than the benchmark and a
-6.8% lower return. Securities within the Internet & Catalog Retail industry,
such as Amazon.com, Inc., which had a 41.5% return, caused -0.8% of drag as the
Fund was underweight the benchmark. The Energy sector reversed 0.9% of
underperformance as the Fund outperformed the benchmark by 41.8%. Several
securities contributed to this outperformance including Rice Energy, Inc., which
had a 59.6% return, and Parsley Energy, Inc., Class A, which had a 25.1% return.

FIRST TRUST MID CAP VALUE ALPHADEX(R) FUND (FNK)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Mid Cap Value AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Mid Cap Value Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an 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 in common stocks that comprise the Index. From the beginning of the
period covered by this report until April 8, 2016, the shares of the Fund traded
on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and
trade on The Nasdaq Stock Market LLC under the ticker symbol "FNK." The Fund
commenced trading on April 20, 2011.

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select value stocks from the
Nasdaq US 600 Mid 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.

(1)   The Defined Mid Cap Value Index was replaced with the Nasdaq AlphaDEX(R)
      Mid Cap Value Index. The new index is substantially similar to the old
      index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 7.93% and 8.11% at NAV and Market Price,
      respectively. That compares to an Index return of 8.16% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FNY's one-year NAV return of 0.03% underperformed the benchmark S&P MidCap
400(R) Growth Index return of 3.32% by -3.29%. The Financials sector contributed
the most during the period to the Fund's return, with a 2.9% contribution
stemming from its high 21.8% allocation and 8.1% return. Amongst this sector,
the REIT industry contributed 4.7% to the Fund's return. REITs had a return of
38.9% during the period. The Consumer Discretionary sector was the Fund's third
highest weighted sector during the period at 17.8% and the Fund's worst
contributing sector with a -2.7% contribution, stemming from its -5.8% return.
The Hotels Restaurants & Leisure industry in particular contributed -1.1% to the
Fund's return due to its higher weighting of 5.1% and return of -4.4%. On a
relative basis, the Fund underperformed the benchmark. The underperformance can
be attributed primarily to the Health Care sector, which was given a 13.9%
allocation during the period, where the Fund underperformed the benchmark by
-10.1%, creating -1.8% of drag. The Life Sciences Tools & Services industry,
within the Health Care sector, was the cause of -0.8% of the underperformance.
The Industrials sector, which was given a weighting of 11.1% during the period,
reversed close to 1.1% of underperformance by outperforming the benchmark by
8.1%. The Airlines industry alone, within the Industrials sector, reversed 0.5%
of underperformance by underweighting the poor performing industry (-26.9%
return).

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

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

PERFORMANCE REVIEW

FYT's one-year NAV return of 0.79% underperformed the benchmark S&P SmallCap
600(R) Value Index return of 8.95% by -8.16%. Several sectors contributed
equally to the Fund's return during the period including the Information
Technology (2% contribution), Industrials (1.9% contribution), Financials (1.7%
contribution), and Utilities (1.6% contribution) sectors. The highest weighted
sector during the period was the Consumer Discretionary sector at 19.4%, but it
had a near flat contribution due to its -8.4% return. The Energy sector was the
worst performing and contributing sector during the period. This sector had a
-40.9% return and -7.1% contribution to the Fund's return. The contribution was
tampered due to its relatively low weighting of 8.5% during the period. On a
relative basis, the Fund underperformed the benchmark. It was the Energy sector
that contributed the most to the relative underperformance. The Fund held the
Energy sector at a 4.2% greater allocation and had a -8.2% lower return, leading
to -4.7% of relative underperformance. The two industries within the Energy
sector, the Oil Gas & Consumable Fuels and Energy Equipment & Services
industries, each contributed about -2.3% to the underperformance, each
overweighting and underperforming the benchmark. The Health Care sector reversed
0.5% of drag by underweighting the benchmark by 3.8% and outperforming the
benchmark by 1.5%.

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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST SMALL CAP GROWTH ALPHADEX(R) FUND (FYC)

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Small Cap Growth AlphaDEX(R) Fund (the "Fund") sought investment
results that corresponded generally to the price and yield (before the Fund's
fees and expenses) of an equity index called the Defined Small Cap Growth Index.
Effective April 8, 2016, the Fund changed its investment objective to seek
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Small
Cap Growth Index (the "Index"). The Fund will normally invest at least 90% of
its net assets in common stocks that comprise the Index. From the beginning of
the period covered by this report until April 8, 2016, the shares of the Fund
traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are
listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FYC."
The Fund commenced trading on April 20, 2011.

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select growth stocks from
the Nasdaq US 700 Small 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.

(1)   The Defined Small Cap Growth Index was replaced with the Nasdaq
      AlphaDEX(R) Small Cap Growth Index. The new index is substantially similar
      to the old index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 12.48% and 12.61% at NAV and Market Price,
      respectively. That compares to an Index return of 12.75% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

18.2% allocation and 19.3% return. Several industries within the Information
Technology sector posted high returns during the period including Diversified
Telecommunication Services (57.9%), IT Services (31.1%), and Semiconductors &
Semiconductor Equipment (29.0%). The Health Care sector was the worst

allocation during the period, the highest amongst the sectors, and a -5.2%
return. The Pharmaceuticals industry returned -27.4% during the period and
contributed -1.6% to the Fund's return. On a relative basis, the Fund

than the benchmark. The sector also had a 6.3% higher return than 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 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, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2011 through July
31, 2016. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

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

From the beginning of the period covered by this report until April 8, 2016, the
First Trust Mega Cap AlphaDEX(R) Fund (the "Fund") sought investment results
that corresponded generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the Defined Mega Cap Index. Effective April
8, 2016, the Fund changed its investment objective to seek investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the Nasdaq AlphaDEX(R) Mega Cap Index (the
"Index"). The Fund will normally invest at least 90% of its net assets in common
stocks that comprise the Index. From the beginning of the period covered by this
report until April 8, 2016, the shares of the Fund traded on the NYSE Arca.
Effective April 8, 2016, the shares of the Fund are listed and trade on The
Nasdaq Stock Market LLC under the ticker symbol "FMK." The Fund commenced
trading on May 12, 2011.

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.

(1)   The Defined Mega Cap Index was replaced with the Nasdaq AlphaDEX(R) Mega
      Cap Index. The new index is substantially similar to the old index.

(2)   Performance data is not available for all the periods shown in the table
      for the index because performance data does not exist for each of the
      entire periods.

(3)   The Fund's cumulative total returns for the period from April 8, 2016
      through July 31, 2016 were 4.86% and 5.19% at NAV and Market Price,
      respectively. That compares to an Index return of 5.10% for the same
      period.

(See Notes to Fund Performance Overview on page 28.)

PERFORMANCE REVIEW

FMK's one-year NAV return of 0.19% underperformed the benchmark S&P 100(R) Index
return of 5.75% by -5.56%. The Information Technology sector was given the
greatest allocation of 22.9% and had a return of 7.5%, leading to a 1.4%
contribution to the Fund's return. In the Information Technology sector, the
Semiconductor & Semiconductor Equipment industry contributed 0.9%, due to its
15.6% return and 6.7% allocation. The Health Care sector deterred -3.5% of Fund
performance as this sector had a -16.9% return and 11.7% allocation. The
Biotechnology industry caused -1.9% of the sector's contribution. The
Biotechnology industry was given an allocation of 4.1% and had a return of
-28.9%. On a relative basis, the Fund underperformed the benchmark. The
underperformance can be largely attributed to the Health Care sector. The Health
Care sector caused -3.3% of underperformance as it had an -18.9% lower return.
The Biotechnology and Pharmaceuticals industries each contributed about -1.1% of
underperformance due to underperforming the benchmark by -16.1% and -23.9%
respectively. The Financials sector reversed 1.7% of underperformance as the
Fund was underweight the benchmark in this poor performing sector (-12.2%
return) by 6.1%. The Banking industry, in particular, was the cause of 1.6% of
the outperformance as the Fund underweighted the benchmark by 4.3% and
outperformed the benchmark by 5.1%.

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, 2016

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, 2016.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this 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
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the 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
Lending Agency Agreement. Securities lent in accordance with the Securities
Lending Agency Agreement on a gross basis were as
follows:

SECURITIES LENDING AGENCY AGREEMENT
------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(1)   $     3,635,971
Non-cash Collateral(2)                            (3,630,397)
                                             ---------------
Net Amount                                   $         5,574
                                             ===============

(1)   The amount presented on the Statements of Assets and Liabilities, which is
      included in "Investments, at value", is not offset and is shown on a gross
      basis.

(2)   The collateral requirements are determined at the beginning of each
      business day based on the market value of the loaned securities from the
      end of the prior day. On July 29, 2016, the last business day of the
      period, there was sufficient collateral based on the end of the day market
      value from the prior business day; however, as a result of market movement
      from July 28 to July 29, the value of the related securities loaned was
      above the collateral value received. See Note 2D - Securities Lending in
      the Notes to Financial Statements.

The Fund's investments in repurchase agreements were all subject to an
enforceable Master Repurchase Agreement. Repurchase Agreements on a gross basis
were as follows:

REPURCHASE AGREEMENTS
------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(3)   $     1,992,351
Non-cash Collateral(4)                            (1,992,351)
                                             ---------------
Net Amount                                   $            --
                                             ===============

(3)   The amount is included in "Investments, at value" on the Statements of
      Assets and Liabilities.

(4)   At July 31, 2016, the value of the collateral received from each seller
      exceeded the value of the repurchase agreements.

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
Lending Agency Agreement. Securities lent in accordance with the Securities
Lending Agency Agreement on a gross basis were as follows:

SECURITIES LENDING AGENCY AGREEMENT
------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(1)   $       675,110
Non-cash Collateral(2)                              (670,565)
                                             ---------------
Net Amount                                   $         4,545
                                             ===============

(1)   The amount presented on the Statements of Assets and Liabilities, which is
      included in "Investments, at value", is not offset and is shown on a gross
      basis.

(2)   The collateral requirements are determined at the beginning of each
      business day based on the market value of the loaned securities from the
      end of the prior day. On July 29, 2016, the last business day of the
      period, there was sufficient collateral based on the end of day market
      value from the prior business day; however, as a result of market movement
      from July 28 to July 29, the value of the related securities loaned was
      above the collateral value received. See Note 2D - Securities Lending in
      the Notes to Financial Statements.

The Fund's investments in repurchase agreements were all subject to an
enforceable Master Repurchase Agreement. Repurchase Agreements on a gross basis
were as follows:

REPURCHASE AGREEMENTS
------------------------------------------------------------
Total gross amount presented on the
   Statements of Assets and Liabilities(3)   $       368,004

(3)   The amount is included in "Investments, at value" on the Statements of
      Assets and Liabilities.

(4)   At July 31, 2016, the value of the collateral received from each seller
      exceeded the value of the repurchase agreements.

                                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 Style Fund. This report covers the twelve Style Funds
listed below. The shares of each Style Fund are listed and traded on The Nasdaq
Stock Market LLC ("Nasdaq").

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 issued and redeemed principally in-kind
for securities included in a Fund's relevant index. Except when aggregated in
Creation Units, each Fund's shares are not redeemable securities.

Effective April 8, 2016, 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, each of which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follow
accounting and reporting guidance under FASB Accounting Standards Codification
Topic 946, "Financial Services-Investment Companies." The following is a summary
of significant accounting policies consistently followed by the 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.


                                                                        Page 127

                                 JULY 31, 2016

A. PORTFOLIO VALUATION

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

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

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than
      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 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 pricing service, does not reflect the security's fair value. As a general
principle, the current fair value of a security would appear to be the amount
which the owner might reasonably expect to receive for the security upon its
current sale. When fair value prices are used, generally they will differ from
market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

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

      6)    relationships among various securities;

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

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

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

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:

                                 JULY 31, 2016

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of July 31, 2016, 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.

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


                                                                        Page 129

of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The dividend and interest earned on the securities loaned is accounted for in
the same manner as other dividend and interest income. At July 31, 2016, all the
Funds except for FMK have securities in the securities lending program.

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

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 Notes. The U.S. Treasury Notes 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 Notes 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 is 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, 2016, were received as
collateral for lending securities.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

Distributions from income and capital gains are determined in accordance with
income tax regulations, which may differ from U.S. GAAP. Certain capital
accounts in the financial statements are periodically adjusted for permanent
differences in order to reflect their tax character. These permanent differences
are primarily due to the varying treatment of income and gain/loss on
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, 2016, 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 the 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 2013, 2014,
2015 and 2016 remain open to federal and state audit. As of July 31, 2016,
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, 2016, the Funds had pre-enactment
and post-enactment net capital losses for federal income tax purposes as shown
in the following table. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to Fund shareholders. The Funds are subject to certain
limitations, under U.S. tax rules, on the use of capital loss carryforwards and
net unrealized built-in losses. These limitations apply when there has been a
50% change in ownership.


                                                                        Page 131

In order to present paid-in capital, accumulated net investment income (loss)
and accumulated net realized gain (loss) on investments on the Statements of
Assets and Liabilities that more closely represent their tax character, certain
adjustments have been made to paid-in capital, accumulated net investment income
(loss) and accumulated net realized gain (loss) on investments. These
adjustments are primarily due to the difference between book and tax treatments
of income and gains on various investment securities held by the Funds and
in-kind transactions. The results of operations and net assets were not affected
by these adjustments. For the fiscal year ended July 31, 2016, the adjustments

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.

Effective April 8, 2016, First Trust Portfolios L.P. ("FTP") entered into
licensing agreements with Nasdaq, Inc. for each of the Style Funds. Prior to
April 8, 2016, FTP had licensing agreements with Standard & Poors Financial

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.

 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 and other services, and excluding 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, 2017.

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

The advisory fee waivers and expense reimbursements for the fiscal year ended
July 31, 2016 and fees waived or expenses borne by First Trust subject to
recovery from the applicable Fund for the periods indicated were as follows:

At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark
Bradley's resignation from his position as the President and Chief Executive
Officer of the Trust, effective December 31, 2015. At the same meeting, the
Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and
Treasurer of the Trust, to serve as the President and Chief Executive Officer,
and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as
the Treasurer, Chief Financial Officer and Chief Accounting Officer of the
Trust.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each Fund's net assets. Each Independent Trustee is also paid an
annual per fund fee that varies based on whether the fund is a closed-end or
other actively managed fund or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
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.

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 June 30, 2017.

                               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.

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

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

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,
each a series of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Funds"),
including the portfolios of investments, as of July 31, 2016, and 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. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Funds
are not required to have, nor were we engaged to perform, an audit of their
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of July 31, 2016 by correspondence with the Funds'
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.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the funds listed above included in the First Trust Exchange-Traded
AlphaDEX(R) Fund as of July 31, 2016, 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.

                                  STYLE FUNDS
                                 JULY 31, 2016

                              RISK CONSIDERATIONS

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

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

CONSUMER DISCRETIONARY COMPANIES RISK. Certain of the Funds invest in consumer
discretionary companies. Consumer discretionary companies are companies that
provide non-essential goods and services, such as retailers, media companies and
consumer services. These companies manufacture products and provide
discretionary services directly to the consumer, and the success of these
companies is tied closely to the performance of the overall domestic and
international economy, interest rates, competition and consumer confidence.
Success depends heavily on disposable household income and consumer spending.
Changes in demographics and consumer tastes can also affect the demand for, and
success of, consumer discretionary products in the marketplace.

ENERGY COMPANIES RISK. Certain of the Funds invest in energy companies. Energy
companies include integrated oil companies that are involved in the exploration,
production and refining process, gas distributors and pipeline-related companies
and other energy companies involved with mining, producing and delivering
energy-related services and drilling. General problems of energy companies
include volatile fluctuations in price and supply of energy fuels, international
politics, terrorist attacks, reduced demand, the success of exploration
projects, clean-up and litigation costs relating to oil spills and environmental
damage, and tax and other regulatory policies of various governments. Natural
disasters such as hurricanes in the Gulf of Mexico also impact the petroleum
industry. Oil production and refining companies are subject to extensive
federal, state and local environmental laws and regulations regarding air
emissions and the disposal of hazardous materials. In addition, oil prices are
generally subject to extreme volatility.

EQUITY SECURITIES RISK. Because the Funds invest in equity securities, the value
of the Funds' shares will fluctuate with changes in the value of these equity
securities. Equity securities prices fluctuate for several reasons, including
changes in investors' perceptions of the financial condition of an issuer or the
general condition of the relevant stock market, such as market volatility, or
when political or economic events affecting the issuers occur. In addition,
common stock prices may be particularly sensitive to rising interest rates, as
the cost of capital rises and borrowing costs increase.

FINANCIAL COMPANIES RISK. Financial companies are especially subject to the
adverse effects of economic recession, currency exchange rates, government
regulation, decreases in the availability of capital, volatile interest rates,
portfolio concentrations in geographic markets and in commercial residential and
real estate loans, and competition from new entrants in their fields of
business.

GROWTH STOCKS INVESTMENT RISK. Certain of the Funds utilize a growth stocks
investment strategy and are thus subject to growth stocks investment risk.
Growth stocks tend to be more volatile than certain other types of stocks and
their prices usually fluctuate more dramatically than the overall stock market.
A stock with growth characteristics can have sharp price declines due to
decreases in current or expected earnings.

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

INDEX CONSTITUENT RISK. One or more of the Funds may be a constituent of one or
more indices. As a result, the Fund may be included in one or more
index-tracking ETFs or mutual funds. Being a component security of such a
vehicle could greatly affect the trading activity involving the 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, the Fund's NAV could be negatively impacted and the Fund's market price
may be significantly below the Fund's net asset value during certain periods In
addition, index rebalances may potentially result in increased trading activity.
To the extent buying or selling activity increases, the Fund can be exposed to
increased brokerage costs and adverse tax consequences and the market price of
the Fund can be negatively affected.

                                 JULY 31, 2016

INDUSTRIALS COMPANIES RISK. Industrials companies convert unfinished goods into
finished durables used to manufacture other goods or provide services. These
companies produce electrical equipment and components , industrial products,
manufactured housing and telecommunications equipment. General risks of these
companies include the general state of the economy, intense competition,
consolidation, domestic and international politics, excess capacity and consumer
demand and spending trends. In addition, they may also be significantly affected
by overall capital spending levels, economic cycles, technical obsolescence,
delays in modernization, labor relations, government regulations and e-commerce
initiatives.

INFORMATION TECHNOLOGY COMPANIES RISK. Certain of the Funds invest in
information technology companies. Information technology companies are generally
subject to the following risks: rapidly changing technologies; short product
life cycles; fierce competition; aggressive pricing and reduced profit margins;
the loss of patent, copyright and trademark protections; cyclical market
patterns; evolving industry standards; and frequent new product introductions.
Information technology companies may be smaller and less experienced companies,
with limited product lines, markets or financial resources and fewer experienced
management or marketing personnel. Information technology company stocks,
especially those which are Internet related, have experienced extreme price and
volume fluctuations that are often unrelated to their operating performance.

MARKET CAPITALIZATION RISK. The Funds normally invest at least 90% of their
assets in common stocks that comprise the applicable Index. The securities of
companies represented in the Indices generally have market capitalizations that
are consistent with the name of each Index. To determine the market
capitalization range of such securities, each Fund uses the current range of the
applicable Index. However, the Funds will not sell a security because the
security has exceeded or fallen below the current market capitalization range of
the applicable Index. Because of market movement, there can be no assurance that
the securities in the Funds will stay within a given market capitalization
range. As a result, the Funds may be exposed to additional risk or may not give
investors the opportunity to invest fully in a given market capitalization
range.

MARKET RISK. Market risk is the risk that a particular security owned by a Fund
or shares of a Fund in general may fall in value. Securities are subject to
market fluctuations caused by such factors as economic, political, regulatory or
market developments, changes in interest rates and perceived trends in
securities prices. Shares of the Funds could decline in value or underperform
other investments.

NON-CORRELATION RISK. A Fund's return may not match the return of its Index for
a number of reasons. For example, a Fund incurs operating expenses not
applicable to its Index, and may incur costs in buying and selling securities,
especially when rebalancing the Fund's portfolio holdings to reflect changes in
the composition of the Index. In addition, a Fund's portfolio holdings may not
exactly replicate the securities included in its Index or the ratios between the
securities included in the Index.

PORTFOLIO TURNOVER RISK. Certain Funds' strategies may frequently involve buying
and selling portfolio securities to rebalance the Funds' exposure to various
market sectors. High portfolio turnover may result in a Fund paying higher
levels of transaction costs and generating greater tax liabilities for
shareholders. Portfolio turnover risk may cause a Fund's performance to be less
than you expect.

REPLICATION MANAGEMENT RISK. The Funds are exposed to additional market risk due
to their policy of investing principally in the securities included in the
Indices. As a result of this policy, securities held by the Funds will generally
not be bought or sold in response to market fluctuations.

SMALLER COMPANIES RISK. Certain of the Funds invest in small and/or mid
capitalization companies. Small and/or mid capitalization companies may be more
vulnerable to adverse general market or economic developments, and their
securities may be less liquid and may experience greater price volatility than
larger, more established companies as a result of several factors, including
limited trading volumes, products or financial resources, management
inexperience and less publicly available information. Accordingly, such
companies are generally subject to greater market risk than larger, more
established companies.

VALUE STOCKS INVESTMENT RISK. Certain of the Funds utilize a value investment
strategy and thus are exposed to value investment risk. The intrinsic value of a
stock with value characteristics may not be fully recognized by the market for a
long time or a stock judged to be undervalued may actually be appropriately
priced at a low level.

                                  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) Funds it manages (the "Funds") in the
United Kingdom 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, 2015, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $9,067,727.
This figure is comprised of $453,849 paid (or to be paid) in fixed compensation
and $8,613,878 paid (or to be paid) in variable compensation. There were a total
of 13 beneficiaries of the remuneration described above. Those amounts include
$5,011,396 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $4,056,331 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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                                 JULY 31, 2016

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2017 at a meeting held on June 13, 2016. The
Board determined for each Fund that the continuation of the Agreement is in the
best interests of the Fund in light of the extent and quality of the services
provided and such other matters as the Board considered to be relevant in the
exercise of its reasonable business judgment.

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 22, 2016 and June 13, 2016, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to 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 or unitary fee rate payable by each
Fund as compared to fees charged to a peer group of funds (all of which were
exchange-traded funds ("ETFs")) compiled by Management Practice, Inc. ("MPI"),
an independent source (the "MPI Peer Group"), and as compared to fees charged to
other clients of the Advisor, including other ETFs managed by the Advisor;
expenses of each Fund as compared to expense ratios of the funds in the Fund's
MPI Peer Group; performance information for each Fund; 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 a special meeting held on April 22, 2016, 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 13, 2016 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 as well as
from the perspective of shareholders. 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 fee 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 and policies. In addition, as part of
the Board's consideration of the Advisor's services, the Advisor, in its written
materials and at the April 22, 2016 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 the Fund's investment objective
and policies.

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, 2017. 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 FNK, FNY, FYT, FYC 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, licensing and other services, but excluding 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 MPI Peer Groups, as well as
advisory fee and unitary fee rates charged by the Advisor to other fund
(including ETFs) and non-fund clients. Because each Fund's MPI Peer Group
included peer funds that pay a unitary fee and because the Unitary Fee Funds 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


                                                                        Page 141

ADDITIONAL INFORMATION (CONTINUED)

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                                 JULY 31, 2016

the total (net) expense ratio of each Non-Unitary Fee Fund and the unitary fee
for each Unitary Fee Fund was above the median total (net) expense ratio of the
peer funds in each Fund's respective MPI Peer Group. With respect to the MPI
Peer Groups, the Board discussed with representatives of 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 clients, the Board considered differences
between the Funds and other 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, 2015 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 consistent with the
Fund's prospectus. 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 stock selection methodology. In addition, the Board
reviewed data prepared by MPI comparing each Fund's performance to its
respective MPI Peer Group and to one or more broad-based benchmark indexes, 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 and 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 expects its expenses to
increase over the next twelve months as the Advisor continues to make
investments in personnel and infrastructure. 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, 2015 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. 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 its management of the Funds' portfolios.

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

(d)   The registrant, during the period covered by this report, has not granted

      instructions.

(e)   Not applicable.

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 2015 and
$420,000 for 2016.

      (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

      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

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

      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

      (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 2015 were $61,425
for the registrant, $12,700 for the registrant's investment adviser and $36,700
for the registrant's distributor, and for 2016 were $61,425 for the registrant,
$23,000 for the registrant's investment adviser and $42,100 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.

or this Item.
