PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its investment objective.

Accordingly, you can lose money investing in a Fund. See "Risk Considerations" at the end 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.

MARKET OVERVIEW

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
ANNUAL REPORT
JULY 31, 2012

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

STATE OF THE ECONOMY/INVESTING

The U.S., while clearly not hitting on all cylinders, is one of the most attractive markets for investors to consider committing capital to, in our opinion. Interest rate levels are near their historic lows in some instances, inflation has declined from 3.6% in July 2011 to 1.4% in July 2012, corporate profits are still relatively strong but expected to strengthen, and, aside from the high unemployment rate, the U.S. economy is performing better than most people realize. The U.S. gross domestic product (GDP) growth rate was 2.3% over the past four quarters (through June 2012). That is actually higher than the 1.7% GDP growth rate for the 10-year period ended June 2012. The Blue Chip Economic Indicators survey of 50 leading economists in early August revealed a 2013 U.S. Gross Domestic Product (GDP) forecast of 2.5%.

Data compiled by the Rockefeller Institute shows that total state tax collections rose 4.7% (year-over-year) in Q1'12, the ninth consecutive quarter in which revenues were up, according to its own release. Eleven states reported double-digit growth. Overall state tax revenues are now above peak levels attained several months into the recession. With respect to the banking industry, data from the Federal Deposit Insurance Corporation (FDIC) revealed that U.S. banks saw their earnings rise 21% (year-over-year) in Q2'12. Industry profits increased for the 12th consecutive quarter, with 89% of banks posting gains.

There are other indications that the economy has taken a turn for the better. The U.S. consumer credit default rate is currently at its lowest point since late 2006, according to the S&P/Experian Consumer Credit Default Composite Index. The default rate stood at 1.5% in July 2012, below the 2.0% level it registered in August 2007, which was just before the start of the financial crisis. The BGOV (Bloomberg Government) Barometer shows that household debt as a percentage of GDP has declined to 83.5%, the lowest level since 2004, and significantly below the all-time high of 97.7% reached during the financial crisis, according to Bloomberg. Zillow Inc. announced that home values posted their first year-over-year increase since 2007 in Q2'12, according to Bloomberg. Residential property values rose 0.2% from Q2'11. Home values rose four consecutive months through June.

U.S. STOCKS AND BONDS

All of the major U.S. stock indices posted gains for the 12-month period ended July 31, 2012. The S&P 500 Index, S&P MidCap 400 Index and S&P SmallCap 600 Index were up 9.1%, 1.2%, and 4.0%, respectively, according to Bloomberg. We could be witnessing a changing of the guard in the market with respect to leadership. Large-cap stocks had lagged mid- and small-caps for the past 3, 5, 10, 15 and 20-year periods (as of 6/30/12), according to Bloomberg. Eight of the 10 major sectors in the S&P 500 posted gains over the past 12 months. The top performing sector was Telecommunication Services, up 30.5%, while the weakest showing came from Materials, down 5.2%. The year-over-year estimated earnings growth rate for the companies in the S&P 500 Index is expected to be 5.4% in 2012 and 13.4% in 2013, according to Standard & Poor's.

The current bull market has lasted 1,240 days (as of 7/31/12). It is the ninth longest on record, according to Bespoke Investment Group. The longest bull market on record lasted 4,494 days (12/4/87-3/24/00). The S&P 500's price-only return from 3/9/09-7/31/12 was 103.9%, also the ninth best on record. The aforementioned longest rally also posted the best return at 582.1%. In the 25 bull markets prior to this one, the average length was 890 days with an average price-only return of 101.6%.

In the U.S. bond market, all of the domestic categories performed well. The onset of economic weakness in Europe, stemming from its ongoing debt crisis, the tempering of growth in China and the drop in inflation in the U.S. and abroad, helped fuel a rally in bonds. The yield on the benchmark 10-Year T-Note fell 133 basis points from 2.80% on 7/29/11 to 1.47% on 7/31/12. Its yield actually hit an all-time low of 1.39% on 7/24/12. Despite concerns from a small number of influential pundits warning there could be a potential spike in the default rate for municipalities (never materialized), the top performing major group by far was tax-free debt. The Barclays Capital Municipal Bond: Long Bond (22+) Index posted a total return of 16.8%. The next closest domestic category was high yield corporate bonds, up 8.1%, as measured by the Barclays Capital U.S. Corporate High Yield Index. Treasuries, while posting a positive return, had the weakest showing of the major categories, up 4.6%, as measured by the Barclays Capital U.S. Treasury: Intermediate Index.

FOREIGN STOCKS AND BONDS

Since the biggest and most pressing concern overseas has been the debt crisis in the European Union, which is comprised of developed nations, investors appeared to be more comfortable with investing in emerging markets debt. The Barclays Capital Global Emerging Markets Index of debt securities rose 8.5% (USD), while the Barclays Capital Global Aggregate Index of higher quality debt returned 1.8% (USD), according to Barclays Capital. Due to the slowing of economic activity abroad, investors did not appear to be enthusiastic about foreign equities in general. The MSCI Emerging Markets Index of stocks declined by 13.9% (USD), while the MSCI World Index (excluding the U.S.) of stocks from developed countries fell 11.6% (USD). The U.S. dollar appreciated 11.8% against a basket of major currencies, as measured by the Dollar Index (DXY).

FUND PERFORMANCE OVERVIEW

FXD - FIRST TRUST CONSUMER DISCRETIONARY ALPHADEX(R) FUND

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 Euronext or its affiliates ("NYSE Euronext"), to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext 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 -3.06% underperformed the benchmark S&P 500(R) Consumer Discretionary Index return of +11.90% by -14.96%. A major cause of the Fund's underperformance was being underweight in large companies that performed well. For example, Home Depot, Inc. (+53.5% one-year return), Comcast Corp. (+38.4%), and Walt Disney Co. (+29.4%) combined for an average weight of 2.3% in the Fund, versus a 16.5% average weight in the benchmark. The three companies contributed +1.0% to the Fund's total return and
+5.9% to the benchmark's performance. The Fund's relative performance was also hindered by being overweight in the Diversified Consumer Services industry relative to the benchmark (3.9% vs. 0.9% average weight). For-profit education companies Education Management Corp. (-83.1% annual return), Career Education Corp. (-79.2%), and DeVry, Inc. (-68.1%) caused the industry to have extremely weak performance for the year covered by this report. In total, the Diversified Consumer Services industry caused -3.7% of the Fund's underperformance.

(1) On or about September 18, 2008, Russell Investment Group ("Russell") began calculating its Russell U.S. Indexes 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.

Performance figures assume reinvestment of all dividend 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.

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, 2007 through July 31, 2012. 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.

FUND PERFORMANCE OVERVIEW (CONTINUED)

FXG - FIRST TRUST CONSUMER STAPLES ALPHADEX(R) FUND

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 NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext constructs the Consumer Staples Index using the RGS sector scheme to determine a stock's sector membership.

FXG's one-year NAV return of -3.03% underperformed the benchmark S&P 500(R) Consumer Staples Index return of +19.67% by -22.70%.

(+45.1% one-year return), Philip Morris International, Inc. (+33.7%), Coca-Cola Co. (+22.2%), Altria Group (+44.5%), and Proctor & Gamble Co. (+8.5%). In total, these companies comprised 48.9% of the benchmark's average weight and contributed +12.6% to the benchmark's total return. The same companies comprised 5.4% of the Fund's average weight and contributed +1.6% to the Fund's total return. The Fund's position in Green Mountain Coffee Roasters, Inc. was another contributor to underperformance. While the company was in the Fund during the year covered by this report, the company returned -66.9% and contributed -4.6% to the Fund's total return. Green Mountain Coffee Roasters, Inc. was not in the benchmark.

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

PERFORMANCE REVIEW

FXN's one-year NAV return of -21.50% underperformed the benchmark S&P 500(R) Energy Index return of -5.03% by -16.47%. In general, the Energy sector had weak performance during the year covered by this report due to global economic uncertainty. Despite the sector's weak performance, oil and gas behemoths Exxon Mobil Corp. (+11.6% one-year return) and Chevron Corp. (+8.8%) had solid returns. Underweighting the two companies were the primary cause of the Fund's underperformance relative to the benchmark as they comprised 43.3% of the benchmark's average weight and contributed +5.4% to the benchmark's performance. In comparison, Exxon and Chevron combined to comprise 5.4% of the Fund's average weight and contributed +0.5% to the Fund's total return.

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 dividend 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.

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, 2007 through July 31, 2012. 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.

FUND PERFORMANCE OVERVIEW (CONTINUED)

FXO - FIRST TRUST FINANCIALS ALPHADEX(R) FUND

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 NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext 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 +4.57% outperformed the benchmark S&P 500(R) Financials Index return of +1.11% by +3.46%. Performance of Financial stocks was mixed for the year covered by this report with Consumer Finance companies posting strong returns, while larger diversified financial companies had poor performance. The Fund's outperformance came from being underweight in a handful of large financial institutions. Citigroup, Inc. (-29.2% one-year return), Bank of America Corp. (-24.0%), Goldman Sachs Group, Inc. (-24.1%), JPMorgan Chase & Co. (-8.3%), and Morgan Stanley (-37.9%) were the largest detractors from the benchmark's performance. The five companies comprised an average of 23.0% of the benchmark's weight and contributed -7.1% to the benchmark's annual performance. The same five banks combined to comprise 4.0% of the Fund's average weight and contributed -0.5% to the Fund's total return. The Consumer Finance industry was a bright spot in the Fund as the Fund's holdings in the industry returned +25.7% for the year. Discover Financial Services and Capital One Financial Corp. led the Fund's holdings in the industry, with one-year returns of +42.2% and +18.7%, respectively.

Performance figures assume reinvestment of all dividend 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, 2012

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, 2007 through July 31, 2012. 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 (CONTINUED)

FXH - FIRST TRUST HEALTH CARE ALPHADEX(R) FUND

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 NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext constructs the Health Care Index using the RGS sector scheme to determine a stock's sector membership.

PERFORMANCE REVIEW

FXH's one-year NAV return of +5.17% underperformed the benchmark S&P 500(R) Health Care Index return of +15.42% by -10.25%. A major cause of the Fund's underperformance was being underweight in large pharmaceutical companies that performed well. Pfizer, Inc. (+30.1% annual return), Merck & Co., Inc. (+35.5%), Abbott Laboratories (+33.7%), Amgen, Inc. (+54.2%), and Johnson & Johnson (+10.8%) were the leading contributors to the benchmark's performance. The five companies combined had an average weight in the benchmark of 43.4% and contributed +11.7% to the benchmark's performance. The same companies combined for an average weight of 5.1% in the Fund and contributed +1.6% to the Fund's total return.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indexes 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.

FUND PERFORMANCE OVERVIEW (CONTINUED)

FXR - FIRST TRUST INDUSTRIALS/PRODUCER DURABLES ALPHADEX(R) FUND

The First Trust Industrials/Producer Durables AlphaDEX(R) Fund (the "Fund") seeks investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the StrataQuant(R) Industrials Index (the "Industrials Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Industrials Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FXR."

The Industrials Index is a modified equal-dollar weighted index designed by NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext constructs the Industrials Index using the RGS sector scheme to determine a stock's sector membership.

PERFORMANCE REVIEW

FXR's one-year NAV return of -0.72% underperformed the benchmark S&P 500(R) Industrials Index return of +6.64% by -7.36%. A major cause of the Fund's underperformance was being underweight in large companies that performed well. General Electric Co. had an average weight in the Fund of 0.5% versus 15.3% in the benchmark. For the year covered by the report, the company returned +20.1%. As a result, General Electric Co. contributed +0.1% to the Fund's total return and +3.0% to the benchmark's performance. Union Pacific Corp. (+22.3% one-year return) and United Parcel Service, Inc. (+12.6%) also caused Fund underperformance by being overweight in the benchmark. The two companies combined to have an average Fund weight of 1.1% versus 9.8% of the benchmark's weight. In terms of contribution to return, the two companies contributed -1.7% to the Fund's underperformance.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indexes 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 dividend 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.

BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2012

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, 2007 through July 31, 2012. 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

FXZ's one-year NAV return of -4.78% outperformed the benchmark S&P 500(R) Materials Index return of -5.20% by +0.42%. Performance in the Fund was relatively flat except for the Metals & Mining industry. Metals & Mining companies in the Fund had a one-year return of -25.9% and contributed -4.5% to the Fund's total return. Cliffs Natural Resources, Inc. was the largest detractor from the Fund's total return. During the time it was held in the Fund for the year covered by this report, Cliffs Natural Resources, Inc. returned -60.1% and contributed -1.5% to the Fund's total return. Though the Metals & Mining industry hurt the Fund's absolute performance, the Fund gained +4.3% in relative performance to the benchmark by being underweight in the industry. Much of the Fund's outperformance in the industry came from having almost no weight invested in Freeport-McMoRan Copper & Gold, Inc., which had a one-year return of -34.4% and an average weight in the benchmark of 9.0%. The Fund lost -2.3% of relative performance by being underweight Monsanto Co. relative to the benchmark. The chemical company had a one-year return of +18.4% and an average weight of 0.9% in the Fund versus an average weight of 9.8% in the benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indexes 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 dividend 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, 2012

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, 2007 through July 31, 2012. 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 (CONTINUED)

FXL - FIRST TRUST TECHNOLOGY ALPHADEX(R) FUND

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 NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext constructs the Technology Index using the RGS sector scheme to determine a stock's sector membership.

PERFORMANCE REVIEW

FXL's one-year NAV return of -3.80% underperformed the benchmark S&P 500(R) Information Technology Index return of +13.05% by -16.85%. The Fund's underperformance was caused by strong performance from large technology companies, which the Fund held at a much lower weight than the benchmark. The benchmark's three largest constituents were Apple, Inc. (+56.4% one-year return), International Business Machines Corp. (+9.6%), and Microsoft Corp. (+10.5%). In total, these companies combined for an average benchmark weight of 38.2% and contributed +10.8% to the benchmark's performance. In comparison, the same companies combined to have an average Fund weight of 3.1% and contributed +1.0% to the Fund's total return.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2012

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, 2007 through July 31, 2012. 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 (CONTINUED)

FXU - FIRST TRUST UTILITIES ALPHADEX(R) FUND

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 NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index 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. NYSE Euronext 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 +6.65% underperformed the benchmark S&P 500(R) Utilities Index return of +19.29% by -12.64%. Much of the Fund's underperformance came from companies that were not held in the benchmark because they are classified by GICS(R) as being from the Telecommunication Services sector. The Fund had an average weight in the sector of 23.4% and the Fund's holdings in the sector returned -23.8%, resulting in -10.5% of Fund underperformance.

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

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. 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 the 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 the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all dividend 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, 2012 (UNAUDITED)

As a shareholder of First Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund or First Trust Utilities AlphaDEX(R) Fund (each a "Fund" and collectively, the "Funds"), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, 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, 2012.

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.

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SECTOR FUNDS
JULY 31, 2012

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 ("SEC") under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty-one funds considered either a Sector Fund or a Style Fund, each type having a separate report. This report covers the nine Sector Funds listed below:

First Trust Consumer Discretionary AlphaDEX(R) Fund - (NYSE Arca, Inc.
("NYSE Arca") ticker "FXD")

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

Each fund represents a separate series of shares of beneficial interest in the Trust (each a "Fund" and collectively, the "Funds"). Each Fund's shares currently are listed and traded on the NYSE Arca. 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, shares are not redeemable securities of a Fund. The investment objective of each Fund is to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of the following indices:

FUND                                                            INDEX

("FTP"), the distributor of the Trust, by Archipelago Holdings, Inc. ("Archipelago"), an affiliate of NYSE Euronext. Prior to the acquisition of the American Stock Exchange LLC (the "AMEX") by NYSE Euronext, the Index was developed,maintained and sponsored by AMEX.

2. SIGNIFICANT ACCOUNTING POLICIES

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. The NAV is calculated 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 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 in accordance with valuation procedures adopted by the Trust's Board of Trustees and in accordance with the 1940 Act. Each Fund's securities will be valued as follows:

Securities listed on any exchange other than the NASDAQ Stock Market, Inc. ("NASDAQ") or the London Stock Exchange Alternative Investment Market ("AIM") are valued at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and asked prices on such day. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SECTOR FUNDS
JULY 31, 2012

Securities listed on the NASDAQ or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there is no official closing price on the valuation day, the securities are valued at the mean of the most recent bid and ask prices on such day.

Securities traded in the over-the-counter market, but excluding securities trading on the NASDAQ or the AIM, are valued at the closing bid prices.

Short-term investments that mature in less than 60 days when purchased are valued at amortized cost.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board of Trustees or its delegate 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 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. The use of fair value prices by a Fund generally results in prices used by the Fund that may differ from current market quotations or official closing prices on the applicable exchange. 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, the use of fair value prices and certain current market quotations or official closing prices could result in a difference between the prices used to calculate a Fund's NAV and the prices used by such Fund's corresponding index, which, in turn, could result in a difference between a Fund's performance and the performance of its underlying index.

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

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

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

o Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund's investments as of July 31, 2012, 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. SECURITIES LENDING

The Funds may lend securities representing up to 20% 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. 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 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. 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 in the form of fees or interest on the investment of any cash received as collateral. The dividend and interest earned on the securities loaned are accounted for in the same manner as other dividend and interest income. At July 31, 2012, FXD has securities in the securities lending program.

D. DIVIDENDS AND DISTRIBUTION TO SHAREHOLDERS

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

On January 23, 2012, the Board of Trustees approved a change to quarterly dividends for each of the Funds. This change will be effective with the filing with the SEC of each Fund's prospectus in November 2012.

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

The tax character of distributions paid by each Fund during the year ended July 31, 2012 was as follows:

                                                           Distributions paid from  Distributions paid from  Distributions paid from

E. 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 2009, 2010, 2011 and 2012 remain open to federal and state audit. As of July 31, 2012, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds' financial statements for uncertain tax positions.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for 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, 2012, the Fund had pre-enactment and post-enactment net capital losses for federal income tax purposes as shown in the following table. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to Fund shareholders. The Funds are subject to certain limitations, under U.S. tax rules, on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership.

In order to present paid-in capital 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, 2012, the adjustments for each Fund were as follows:

F. 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 a licensing agreement with Archipelago for each of the Sector Funds. The license agreement allows for the use by FTP of certain trademarks and trade names of Archipelago and certain trademarks and trade names of NYSE Euronext. The Funds and First Trust Advisors L.P. ("First Trust" or the "Advisor") are sub-licensees to the license agreement. The Funds are required to pay licensing fees, which are shown on the Statements of Operations.

G. ACCOUNTING PRONOUNCEMENTS

In April 2011, the Financial Accounting Standards Board ("FASB") released Accounting Standards Update ("ASU") No. 2011-03, "Reconsideration of Effective Control for Repurchase Agreements." This ASU amends FASB Accounting Standards Codification ("ASC") Topic 860, "Transfers and Servicing"; specifically the criteria required to determine whether a repurchase agreement and similar agreements should be accounted for as sales of financial assets or secured borrowings with commitments. This ASU is effective for fiscal years and interim periods beginning on or after December 15, 2011. Management has concluded that the adoption of ASU No. 2011-03 is not expected to have a material impact on the Funds' financial statements and the accompanying notes, net assets or results of operations.

In May 2011, FASB issued ASU No. 2011-04 "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs", modifying Topic 820, "Fair Value Measurements and Disclosures". At the same time, the International Accounting Standards Board ("IASB") issued International Financial Reporting Standard ("IFRS") 13, "Fair Value Measurement." The objective by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, the ASU requires reporting entities to disclose (i) the amounts of any transfers between Level 1 and Level 2, and the reasons for the transfers, (ii) for Level 3 fair value measurements, quantitative information about significant unobservable inputs used, (iii) a description of the valuation processes used by the reporting entity, and (iv) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of the ASU is for interim and annual periods beginning after December 15, 2011. Management is currently evaluating the impact of the updated standards on the Funds' financial statements, if any.

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. 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 other 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, taxes and extraordinary expenses) exceed 0.70% of average daily net assets per year (the "Expense Cap"). The Expense Cap, pursuant to a contractual agreement, will be in effect until at least November 30, 2013.

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, if any, would be included in "Expenses previously waived or reimbursed" on the Statements of Operations.

5. CREATION, REDEMPTION & TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 50,000 shares. 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. Purchasers of 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
        101-200                     $1,000
        201-300                     $1,500
        301-400                     $2,000
        401-500                     $2,500
        501-600                     $3,000
        601-700                     $3,500

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 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.

Parties 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
       101-200                      $1,000
       201-300                      $1,500
       301-400                      $2,000
       401-500                      $2,500
       501-600                      $3,000
       601-700                      $3,500

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 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, the Funds will not pay 12b-1 fees any time before November 30, 2013.

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 "Fund"), including the portfolios of investments, as of July 31, 2012, 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 Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

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

Our procedures included confirmation of securities owned as of July 31, 2012 by correspondence with the Fund's custodian and brokers; where replies were not received, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the funds listed above included in the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2012, 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 the each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

ADVISORY AGREEMENT

BOARD CONSIDERATIONS REGARDING APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

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

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

The Board approved the continuation of the Agreement for a one-year period ending March 31, 2013, for each Fund at a meeting held on March 11-12, 2012. The Board of Trustees determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the services, expenses 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. To assist the Board in its evaluation of the Agreement for each Fund, the Independent Trustees received a report in advance of the Board meeting responding to a request for information from counsel to the Independent Trustees. The report, 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 for each Fund as compared to fees charged to a peer group of Funds compiled by Lipper Inc. ("Lipper"), an independent source (the "Lipper Expense Group"), and as compared to fees charged to other clients of the Advisor with similar investment objectives and to other exchange-traded funds ("ETFs") managed by the Advisor; expenses of each Fund compared to expense ratios of the funds in the Fund's Lipper Expense Group; 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; fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P.; and a summary of the Advisor's compliance program. Following receipt of this information, counsel to the Independent Trustees posed follow-up questions to the Advisor, and the Independent Trustees and their counsel then met separately to discuss the information provided by the Advisor, including the supplemental responses. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor is a reasonable business arrangement from each Fund's perspective as well as from the perspective of shareholders. 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 investment advisory fee. The Board also considered that the Agreement was approved by shareholders of each Fund at meetings held in December 2010.

In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of services provided 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 the services provided by the Advisor to the Funds. The Board also considered the background and experience of the persons responsible for the day-to-day management of the Funds. The Board considered the compliance program that had been developed by the Advisor and the procedures in place to monitor each Fund's investment program. In light of the information presented and the considerations made, the Board concluded that the nature, quality and extent of services provided to the Trust and each Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with its investment objective and policies.

The Board considered the advisory fees payable by each Fund under the Agreement. The Board considered that the Advisor agreed to extend the current expense cap for each Fund through November 30, 2013. For each Fund, the Board noted that expenses borne by the Advisor are to be subject to reimbursement by the Fund for up to three years from the date the fee or expense was incurred, 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 by the Advisor. The Board considered the fees charged by the Advisor to other ETFs and other advisory clients with investment objectives and policies similar to the Funds', noting that those fees generally were similar

to the fees charged to the Funds. In addition, the Board received data prepared by Lipper showing the management fees and expense ratios of each Fund as compared to the Fund's Lipper Expense Group. Because each Fund's Lipper Expense Group included peer funds that pay a unitary fee, the Board determined that the Funds' expense ratios were the more relevant data point. Based on the information provided, the Board noted that the total (net) expense ratio of each Fund was above the median of the Fund's Lipper Expense Group. The Board discussed with representatives of the Advisor the limitations in creating a relevant peer group for each Fund, including that (i) many of the Funds are unique in their composition, which makes assembling peers with similar strategies and asset mix difficult and (ii) Lipper omitted certain peer funds due to size that are otherwise logical and appropriate comparisons based on style, strategy and objective. The Board took these limitations into account in considering the Lipper data. The Board also considered information regarding First Trust ETFs from a February 2012 report from Cogent Research on ETF investors.

The Board considered performance information for each Fund, noting that the performance information included each Fund's quarterly performance report, which is part of the process that the Board has established for monitoring each Fund's performance on an ongoing basis. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board also considered information regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, the Fund's tracking error and the Fund's excess return as compared to a benchmark index. 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 error for each Fund was consistent with the target set forth in the Fund's prospectus. In addition, the Board received data prepared by Lipper comparing each Fund's performance to a peer group selected by Lipper (the "Lipper Performance Group") and to a broad-based benchmark. In reviewing each Fund's performance as compared to the performance of the Fund's Lipper Performance Group, the Board took into account the limitations described above with respect to creating relevant peer groups for the Funds.

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

The Board noted that the Advisor has continued to invest in personnel and infrastructure and considered whether fee levels reflect any economies of scale for the benefit of shareholders. The Board concluded that the advisory fee for each Fund reflects an appropriate level of sharing of any economies of scale at current asset levels. The Board also considered the costs of the services provided and profits realized by the Advisor from serving as investment advisor to each Fund for the twelve months ended December 31, 2011, as set forth in the materials provided to the Board. Based on the information provided, the Board concluded that the pre-tax profits estimated to have been realized by the Advisor in connection with the management of each Fund for calendar year 2011 were not unreasonable. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and First Trust Portfolios L.P. their exposure to investors and brokers who, in the absence of the Funds, may have had no dealings with the Advisor, 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 Trust and each Fund. No single factor was determinative in the Board's analysis.

RISK CONSIDERATIONS

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SECTOR FUNDS
JULY 31, 2012 (UNAUDITED)

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.

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

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

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

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

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

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

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

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

Each Fund is considered to be non-diversified. As a result, each Fund is exposed to additional market risk. A non-diversified fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, changes in the market value of a single portfolio security could cause greater fluctuations in share price than would occur in a diversified fund. Furthermore, non-diversified funds are more susceptible to any single political, regulatory or economic occurrence.

Each Fund is not actively managed. A Fund may be affected by a general decline in certain market segments relating to a Fund's corresponding index. A Fund invests in securities included in or representative of its corresponding index regardless of its investment merit. A Fund generally will not attempt to take defensive positions in declining markets.

RISK CONSIDERATIONS (CONTINUED)

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SECTOR FUNDS
JULY 31, 2012 (UNAUDITED)

and the First Trust Utilities AlphaDEX(R) Fund may invest in small capitalization and/or mid capitalization companies. Such 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.

The First Trust Consumer Discretionary AlphaDEX(R) Fund invests in the securities of companies in the consumer discretionary sector. Companies in the consumer discretionary sector 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.

The First Trust Consumer Staples AlphaDEX(R) Fund invests in the securities of companies in the consumer staples sector. Companies in the consumer staples sector provide products directly to the consumer that are typically considered non-discretionary items based on consumer purchasing habits and may be affected by a variety of factors which could impact company profitability. For instance, government regulations may affect the permissibility of using various food additives and the production methods of companies that manufacture food products.

The First Trust Energy AlphaDEX(R) Fund invests in the securities of companies in the energy sector. The companies in the energy sector 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 issuers in the energy sector 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 will 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 have been extremely volatile.

The First Trust Financials AlphaDEX(R) Fund invests in the securities of companies in the financials sector. Banks, thrifts and their holding companies are especially subject to the adverse effects of economic recession; 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. In addition, the Fund may invest in companies that may be significantly affected by the downturn in the U.S. and world economies that began with the significant decline in the subprime mortgage lending market in the United States.

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

The First Trust Industrials/Producer Durables AlphaDEX(R) Fund invests in the securities of companies in the industrials and producer durables sectors. Many companies in these sectors convert unfinished goods into finished durables used to manufacture other goods or provide services. Some industries included in these sectors are 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.

The First Trust Materials AlphaDEX(R) Fund invests in the securities of companies in the materials sector. Companies in the materials sector are involved in the extracting or processing of raw materials. General risks of these companies include the general state of the economy, consolidation, domestic and international politics and excess capacity. In addition, 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.

The First Trust Technology AlphaDEX(R) Fund invests in the securities of companies in the technology sector. General risks of technology companies include the risks of rapidly changing technologies, short product life cycles, fierce competition, aggressive pricing and reduced profit margins, loss of patent, copyright and trademark protections, cyclical market patterns, evolving industry standards, and frequent new product introductions. Technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel.

RISK CONSIDERATIONS (CONTINUED)

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SECTOR FUNDS
JULY 31, 2012 (UNAUDITED)

The First Trust Utilities AlphaDEX(R) Fund invests in the securities of companies in the utilities sector. General problems of issuers in the utilities sector 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.

Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of a Fund's assets can decline as can the value of a Fund's distributions. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

The Funds may invest in non-U.S. securities publicly traded in the United States. Securities issued by non-U.S. companies present risks beyond those of securities of U.S. issuers. Risks of investing in non-U.S. securities include:
different accounting standards; expropriation, nationalization or other adverse political or economic developments; currency devaluation, blockages or transfer restrictions; changes in non-U.S. currency exchange rates; taxes; restrictions on non-U.S. investments and exchange of securities; and less government supervision and regulation of issuers in non-U.S. countries. Prices of non-U.S. securities also may be more volatile.

NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE

MARKET OVERVIEW

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
ANNUAL REPORT
JULY 31, 2012

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

STATE OF THE ECONOMY/INVESTING

The U.S., while clearly not hitting on all cylinders, is one of the most attractive markets for investors to consider committing capital to, in our opinion. Interest rate levels are near their historic lows in some instances, inflation has declined from 3.6% in July 2011 to 1.4% in July 2012, corporate profits are still relatively strong but expected to strengthen, and, aside from the high unemployment rate, the U.S. economy is performing better than most people realize. The U.S. gross domestic product (GDP) growth rate was 2.3% over the past four quarters (through June 2012). That is actually higher than the 1.7% GDP growth rate for the 10-year period ended June 2012. The Blue Chip Economic Indicators survey of 50 leading economists in early August revealed a 2013 U.S. Gross Domestic Product (GDP) forecast of 2.5%.

Data compiled by the Rockefeller Institute shows that total state tax collections rose 4.7% (year-over-year) in Q1'12, the ninth consecutive quarter in which revenues were up, according to its own release. Eleven states reported double-digit growth. Overall state tax revenues are now above peak levels attained several months into the recession. With respect to the banking industry, data from the Federal Deposit Insurance Corporation (FDIC) revealed that U.S. banks saw their earnings rise 21% (year-over-year) in Q2'12. Industry profits increased for the 12th consecutive quarter, with 89% of banks posting gains.

There are other indications that the economy has taken a turn for the better. The U.S. consumer credit default rate is currently at its lowest point since late 2006, according to the S&P/Experian Consumer Credit Default Composite Index. The default rate stood at 1.5% in July 2012, below the 2.0% level it registered in August 2007, which was just before the start of the financial crisis. The BGOV (Bloomberg Government) Barometer shows that household debt as a percentage of GDP has declined to 83.5%, the lowest level since 2004, and significantly below the all-time high of 97.7% reached during the financial crisis, according to Bloomberg. Zillow Inc. announced that home values posted their first year-over-year increase since 2007 in Q2'12, according to Bloomberg. Residential property values rose 0.2% from Q2'11. Home values rose four consecutive months through June.

U.S. STOCKS AND BONDS

All of the major U.S. stock indices posted gains for the 12-month period ended July 31, 2012. The S&P 500 Index, S&P MidCap 400 Index and S&P SmallCap 600 Index were up 9.1%, 1.2%, and 4.0%, respectively, according to Bloomberg. We could be witnessing a changing of the guard in the market with respect to leadership. Large-cap stocks had lagged mid- and small-caps for the past 3, 5, 10, 15 and 20-year periods (as of 6/30/12), according to Bloomberg. Eight of the 10 major sectors in the S&P 500 posted gains over the past 12 months. The top performing sector was Telecommunication Services, up 30.5%, while the weakest showing came from Materials, down 5.2%. The year-over-year estimated earnings growth rate for the companies in the S&P 500 Index is expected to be 5.4% in 2012 and 13.4% in 2013, according to Standard & Poor's.

The current bull market has lasted 1,240 days (as of 7/31/12). It is the ninth longest on record, according to Bespoke Investment Group. The longest bull market on record lasted 4,494 days (12/4/87-3/24/00). The S&P 500's price-only return from 3/9/09-7/31/12 was 103.9%, also the ninth best on record. The aforementioned longest rally also posted the best return at 582.1%. In the 25 bull markets prior to this one, the average length was 890 days with an average price-only return of 101.6%.

In the U.S. bond market, all of the domestic categories performed well. The onset of economic weakness in Europe, stemming from its ongoing debt crisis, the tempering of growth in China and the drop in inflation in the U.S. and abroad, helped fuel a rally in bonds. The yield on the benchmark 10-Year T-Note fell 133 basis points from 2.80% on 7/29/11 to 1.47% on 7/31/12. Its yield actually hit an all-time low of 1.39% on 7/24/12. Despite concerns from a small number of influential pundits warning there could be a potential spike in the default rate for municipalities (never materialized), the top performing major group by far was tax-free debt. The Barclays Capital Municipal Bond: Long Bond (22+) Index posted a total return of 16.8%. The next closest domestic category was high yield corporate bonds, up 8.1%, as measured by the Barclays Capital U.S. Corporate High Yield Index. Treasuries, while posting a positive return, had the weakest showing of the major categories, up 4.6%, as measured by the Barclays Capital U.S. Treasury: Intermediate Index.

FOREIGN STOCKS AND BONDS

Since the biggest and most pressing concern overseas has been the debt crisis in the European Union, which is comprised of developed nations, investors appeared to be more comfortable with investing in emerging markets debt. The Barclays Capital Global Emerging Markets Index of debt securities rose 8.5% (USD), while the Barclays Capital Global Aggregate Index of higher quality debt returned 1.8% (USD), according to Barclays Capital. Due to the slowing of economic activity abroad, investors did not appear to be enthusiastic about foreign equities in general. The MSCI Emerging Markets Index of stocks declined by 13.9% (USD), while the MSCI World Index (excluding the U.S.) of stocks from developed countries fell 11.6% (USD). The U.S. dollar appreciated 11.8% against a basket of major currencies, as measured by the Dollar Index (DXY).

FUND PERFORMANCE OVERVIEW

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

The First Trust Large Cap Core AlphaDEX(R) Fund (the "Fund") seeks investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Defined Large Cap Core Index (the "Large Cap Core Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Large Cap Core Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FEX."

The Large Cap Core Index is a modified equal-dollar weighted index designed by Standard & Poor's, a division of McGraw-Hill Companies, Inc. ("S&P") to objectively identify and select stocks from the S&P 500(R) Index 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.

PERFORMANCE REVIEW

FEX's one-year NAV return of +2.20% underperformed the benchmark S&P 500(R) Index return of +9.13% by -6.93%. The Information Technology sector was a major cause of Fund underperformance relative to the benchmark. The benchmark's holdings in the sector were heavily concentrated in large companies such as Apple, Inc. (+56.4% annual return) and Intel (+19.0%) where the Fund had much less concentrated holdings. As a result, the Fund's holdings from the Information Technology sector returned -3.5% versus +13.0 for the benchmark's constituents from the sector. In total, the Information Technology sector caused -2.5% of Fund underperformance relative to the benchmark. The Health Care sector was another source of FEX's underperformance relative to the benchmark. The benchmark's concentration in large pharmaceutical companies such as Abbott Laboratories (+33.7% annual return), Merck & Co., Inc. (+35.5%), and Pfizer, Inc. (+30.1%) was the major cause of the benchmark's outperformance relative to FEX within the sector. In total, the Fund's holdings in the Health Care sector returned +2.9% versus +15.4% for the benchmark's constituents in the sector, resulting in -1.4% of Fund underperformance.

Performance figures assume reinvestment of all dividend 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.

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, 2007 through July 31, 2012. 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.

PERFORMANCE REVIEW

FNX's one-year NAV return of +0.66% underperformed the benchmark S&P MidCap 400 Index return of +1.20% by -0.54%. On the positive side, the Fund's holdings in the Utilities sector had a one-year return of +14.7% and contributed +0.8% to total return. Electric Utilities did particularly well with a +20.7% one-year return. The Industrials sector was the heaviest weighted sector in the Fund with a +21.1% average weight. This helped it be the top contributing sector with a
+1.6% contribution even though the Fund's holdings in the sector had a one-year return of +2.9%. On the negative side, the Energy sector was by far the worst-performing sector as the Fund's Energy holdings had a -35.0% return. The sector contributed -2.8% to the Fund's total return. Being overweight the Energy sector relative to the benchmark cost the Fund -0.7% in performance against the benchmark.

Performance figures assume reinvestment of all dividend 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.

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, 2007 through July 31, 2012.

FUND PERFORMANCE OVERVIEW (CONTINUED)

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

The First Trust Small Cap Core AlphaDEX(R) Fund (the "Fund") seeks investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Defined Small Cap Core Index (the "Small Cap Core Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Small Cap Core Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FYX."

The Small Cap Core Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P SmallCap 600 Index 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.

PERFORMANCE REVIEW

FYX's one-year NAV return of +1.42% underperformed the benchmark S&P SmallCap 600 Index return of +3.99% by -2.57%. The Consumer Discretionary sector was the top contributing sector to the Fund's total return with a +2.0% contribution to total return. The Fund's holdings in the sector had a total return of +8.2% and an average weight in the Fund of 21.5% for the year. The Specialty Retail industry was responsible for +1.0% of the sector's contribution to the Fund. The Fund's holdings in the industry returned +15.3% for the year. The Financials sector was the best performing sector in the Fund as the Fund's holdings in the sector had a one-year total return of +15.1% and contributed +1.6% to the Fund's total return. Commercial banks were the best performing component of the Financials sector. The Fund's Commercial Bank holdings had an annual return of
+24.9%. The Industrials sector was the worst contributing sector in the Fund with a -1.1% contribution to the Fund's total return. Within the sector, it was the Commercial Services & Supplies industry that did the most damage. Companies such as Standard Register Co. (-76.2% one-year return) and Consolidated Graphics, Inc. (-54.0%) caused the industry to contribute -0.4% to the Fund's total return. On a relative basis, underperformance in the Industrials sector and an underweight position in the Financials sector relative to the benchmark contributed -1.7% to the Fund's underperformance of the benchmark.

PERFORMANCE REVIEW

FTA's one-year NAV return of +4.96% underperformed the benchmark S&P 500(R) Value Index return of +7.73% by -2.77%. The Utilities sector was the best-performing and top-contributing sector in the Fund. The Fund's holdings in the sector had a one year total return of +19.1% and contributed +2.2% to the Fund's total return. The Industrials sector was the next best contributing sector with a +1.6% contribution. Solid performance from the Fund's holdings in the Industrial Conglomerates industry (+14.7% one-year return) and the Electrical Equipment industry (+13.9%) boosted the performance of the Fund's holdings in the Industrials sector to +7.0%. The Fund's holdings in the Energy sector had a one-year return of -10.5% versus +1.0% for the benchmark's constituents in the sector. A main reason for the Fund's performance lag relative to the benchmark was the benchmark's large concentration in Exxon Mobil Corp. (+11.6% one-year return) and Chevron Corp. (+8.8%). In total, the Energy sector caused -1.6% of Fund underperformance.

Performance figures assume reinvestment of all dividend 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, 2012

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, 2007 through July 31, 2012. 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 (CONTINUED)

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

The First Trust Large Cap Growth 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 Defined Large Cap Growth Index (the "Large Cap Growth Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Large Cap Growth Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FTC."

The Large Cap Growth Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P 500(R) Growth Index 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.

PERFORMANCE REVIEW

FTC's one-year NAV return of -1.89% underperformed the benchmark S&P 500(R) Growth Index return of +10.38% by -12.27%. The Information Technology sector was a major cause of Fund underperformance. The benchmark's holdings in the sector were heavily concentrated in large companies such as Apple, Inc. (+56.4% annual return) and Intel (+19.0%) where the Fund had much less concentrated holdings. As a result, the Fund's holdings from the Information Technology sector returned -1.5% versus +17.0% for the benchmark's constituents from the sector. In total, the Information Technology sector caused -3.8% of Fund underperformance. The Health Care sector was another source of Fund underperformance. The benchmark's concentration in large pharmaceutical companies such as Abbott Laboratories (+33.7% annual return), and Merck & Co., Inc. (+35.5%) was the major cause of the Fund's underperformance within the sector relative to the benchmark. In total, the Fund's holdings in the Health Care sector returned -0.5% versus
+14.3% for the benchmark's constituents in the sector, resulting in -1.9% of Fund underperformance relative to the benchmark. A third cause of underperformance came from the Financials sector, where the Fund's holdings underperformed the benchmark's return -6.91% versus +11.8% for the year. One source of the Fund's lagging return in the sector was the REIT industry where the Fund's holdings returned +3.9% versus +22.4% for the benchmark's constituents in the industry. In total, the Financials sector caused -1.2% of Fund underperformance.

Performance figures assume reinvestment of all dividend 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, 2012

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, 2007 through July 31, 2012. 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 (CONTINUED)

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

The First Trust Multi Cap Value AlphaDEX(R) Fund (the "Fund") seeks investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Defined Multi Cap Value Index (the "Multi Cap Value Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Multi Cap Value Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FAB."

The Multi Cap Value Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P Composite 1500 Value Index 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.

PERFORMANCE REVIEW

FAB's one-year NAV return of +3.62% underperformed the benchmark S&P Composite 1500 Value Index return of +7.18% by -3.56%. The Utilities sector was the best performing and top-contributing sector in the Fund. The Fund's holdings in the sector returned +18.1% and contributed +1.6% to the Fund's total return for the year. Behind the Utilities sector, the Fund's holdings in the Financials sector returned +8.2% for the year to be the second-best performing sector in the Fund. Consumer Finance companies Discover Financial Services (+42.2% one-year return) and Capital One Financial Corp. (+18.7%) boosted the Financials sector's return. The Fund's holdings in the Energy sector returned -19.4% for the year and contributed -1.5% to the Fund's total return, making it the worst performing and contributing sector in the Fund. The Fund's significant underweight position in energy companies Exxon Mobil Corp. (+11.6% one-year return) and Chevron Corp. (+8.8%) caused the Fund's holdings in the Energy sector to underperform the benchmark's constituents in the sector -19.4% versus -0.7% for the year. This resulted in -1.9% of Fund underperformance relative to the benchmark. The Telecommunication Services sector also caused the Fund to underperform its benchmark. Most of the benchmark's allocation to the sector was in AT&T, Inc. (+37.1% one-year return). The Fund had more diverse holdings in the sector, which returned +1.6% for the year. In total, the Telecommunication Services sector caused -1.0% of Fund underperformance relative to the benchmark.

FUND PERFORMANCE OVERVIEW (CONTINUED)

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

The First Trust Multi Cap Growth 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 Defined Multi Cap Growth Index (the "Multi Cap Growth Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Multi Cap Growth Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FAD."

The Multi Cap Growth Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P Composite 1500 Growth Index 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.

PERFORMANCE REVIEW

FAD's one-year NAV return of -1.10% underperformed the benchmark S&P Composite 1500 Growth Index return of +9.25% by -10.35%. The Information Technology sector was the main cause of Fund underperformance. Not only was the Fund underweight in the sector relative to the benchmark, but the Fund's performance in the sector lagged due to being underweight in large companies that performed well in general. For example, the benchmark had an average weight of 6.3% in Apple, Inc. (+56.4% one-year return) versus the Fund's average weight of 0.4% in the company. Intel (+19.0% one-year return) and Microsoft (+10.5%) were other examples of large companies with strong performance that the Fund was significantly underweight relative to the benchmark. In total, the Fund's holdings in the Information Technology sector returned +0.6% versus +15.9% for the benchmark's constituents in the sector. The Health Care sector was another cause of Fund underperformance as the Fund's underweight position in large pharmaceutical companies caused the Fund's performance in the sector to lag the benchmark's +1.3% versus +13.8% for the year. Abbott Laboratories (+33.7% one-year return), and Merck & Co. Inc., (+35.5%) were two examples of large pharmaceutical companies that the Fund was significantly underweight relative to the benchmark. In total, the Information Technology and Health Care sectors contributed -6.7% to the Fund's total return.

Performance figures assume reinvestment of all dividend 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.

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, 2007 through July 31, 2012. 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.

PERFORMANCE REVIEW

FNK's one-year NAV return of +3.23% outperformed the benchmark S&P MidCap 400 Value Index return of +3.01% by +0.22%. The Utilities sector was the best performing sector in the Fund. The Fund's holdings in the sector had a total return of +17.3% and contributed +1.4% to the Fund's total return for the year. Behind Utilities, the Financials sector was the second-best performing sector with a one-year return of +13.0%. Companies from the Insurance industry returned
+17.7% in the Fund giving the sector a performance boost. In total, the Financials sector contributed +1.6% to the Fund's total return. The Energy sector was by far the worst performing sector in the Fund with a -42.2% one-year return. In relative terms, the Fund managed slight outperformance of its benchmark. Being overweight the Energy sector and underperformance within the Consumer Discretionary sector caused a drag in the Fund's relative performance; however, the drag was made up by outperformance within the Industrials and Health Care sectors.

Performance figures assume reinvestment of all dividend 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.

FUND PERFORMANCE OVERVIEW (CONTINUED)

FNY - FIRST TRUST MID CAP GROWTH ALPHADEX(R) FUND

The First Trust Mid Cap Growth 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 Defined Mid Cap Growth Index (the "Mid Cap Growth Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Mid Cap Growth Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FNY."

The Mid Cap Growth Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P(R) MidCap 400 Growth Index 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.

PERFORMANCE REVIEW

FYT's one-year NAV return of +0.75 underperformed the benchmark S&P SmallCap 600 Value Index return of +4.26% by -3.51%. The Financials sector was the top-performing and contributing sector in the Fund. The Fund's holdings from the sector returned +25.0% and contributed +2.1% to the Fund's total return for the year. Insurance companies performed particularly well as the Fund's holdings in the industry had a one-year return of +32.8% and contributed +1.1% to the Fund's total return. Just behind the Financials sector in contribution was the Consumer Discretionary sector with a +2.0% contribution. The Fund's holdings in the sector returned +7.7% and had an average weight in the Fund of +21.8% for the year. The Industrials sector was the largest detractor from the Fund's total return with a -1.2% contribution to total return. The Fund's holdings in the sector returned -6.7% and had an average Fund weight of 17.8% for the year. The Aerospace & Defense industry was a primary cause of the sector's poor performance as the companies from the industry had a one-year return of -23.4%. In relative terms, the Fund's underweight position in the Financials and Utilities sectors relative to the benchmark caused -2.7% of Fund underperformance relative to the benchmark.

Performance figures assume reinvestment of all dividend 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.

FUND PERFORMANCE OVERVIEW (CONTINUED)

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

The First Trust Small Cap Growth 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 Defined Small Cap Growth Index (the "Small Cap Growth Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Small Cap Growth Index. The shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol "FYC."

The Small Cap Growth Index is a modified equal-dollar weighted index designed by S&P to objectively identify and select stocks from the S&P(R) SmallCap 600 Growth Index 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.

PERFORMANCE REVIEW

FMK's one-year NAV return of -3.78% underperformed the benchmark S&P 100 Index return of +12.29% by -16.07%. The Energy sector caused the most underperformance of any sector in the Fund. For the year covered by this report the Fund's holdings in the sector returned -15.0% versus -2.1% for the benchmark's Energy constituents. The Fund's relative overweight positions in Apache Corp. (-29.9% one-year return) and Halliburton Co. (-38.9%) and relative underweight position in Exxon Mobil Corp. (+11.6%) contributed to the performance discrepancy. In total, the Energy sector caused -3.8% of Fund underperformance. The Consumer Discretionary sector was the second worst sector in terms of Fund underperformance. The Fund's holdings in the sector returned -3.9% for the year versus +17.6% for the benchmark. The major cause of the performance lag within the sector was the Fund's overweight position in the poor-performing Automobiles industry. The Fund's holdings in the Automobiles industry had a one-year return of -31.3% and made up an average of 3.7% of the Fund's weight. In comparison, the benchmark had an average weight of only 0.6% in the industry. In total, the Consumer Discretionary sector caused -3.6% of Fund underperformance. The Fund also received -2.4% of underperformance from the Information Technology sector, mostly from the Fund being overweight in Hewlett-Packard Co. (-47.1% one-year return) and underweight in Apple, Inc. (+56.4%) relative to the benchmark.

Performance figures assume reinvestment of all dividend 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, 2012

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 May 12, 2011 (commencement of trading) through July 31, 2012. 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. 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 the 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 the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all dividend 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, 2012 (UNAUDITED)

As a shareholder of First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth AlphaDEX(R) Fund, First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust Small Cap Growth AlphaDEX(R) Fund or First Trust Mega Cap AlphaDEX(R) Fund
(each a "Fund" and collectively, the "Funds"), you incur two types of costs: (1)
transaction costs; and (2) ongoing costs, including management fees, distribution and/or service fees, 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, 2012.

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.

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

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

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

Each fund represents a separate series of shares of beneficial interest in the Trust (each a "Fund" and collectively, the "Funds"). Each Fund's shares currently are listed and traded on the NYSE Arca. 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, shares are not redeemable securities of a Fund. 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 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. The NAV is calculated 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 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 in accordance with valuation procedures adopted by the Trust's Board of Trustees and in accordance with the 1940 Act. Each Fund's securities will be valued as follows:

Securities listed on any exchange other than the NASDAQ Stock Market, Inc. ("NASDAQ") or the London Stock Exchange Alternative Investment Market ("AIM") are valued at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and asked

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

prices on such day. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

Securities listed on the NASDAQ or the AIM are valued at the official closing price on the business day as of which such value is being determined. If there is no official closing price on the valuation day, the securities are valued at the mean of the most recent bid and ask prices on such day.

Securities traded in the over-the-counter market, but excluding securities trading on the NASDAQ or the AIM, are valued at the closing bid prices.

Short-term investments that mature in less than 60 days when purchased are valued at amortized cost.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Board of Trustees or its delegate 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 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. The use of fair value prices by a Fund generally results in prices used by the Fund that may differ from current market quotations or official closing prices on the applicable exchange. 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, the use of fair value prices and certain current market quotations or official closing prices could result in a difference between the prices used to calculate a Fund's NAV and the prices used by such Fund's corresponding index, which, in turn, 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 investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. A summary of the inputs used to value each Fund's investments as of July 31, 2012, 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 are 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. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:

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

On January 23, 2012, the Board of Trustees approved a change to quarterly dividends for each of the Funds. This change will be effective with the filing with the SEC of the annual update to each Fund's annual prospectus in November 2012.

Distributions from income and capital gains are determined in accordance with income tax regulations, which may differ from

U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.

The tax character of distributions paid by each Fund during the year ended July 31, 2012 was as follows:

D. 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 distribution 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 2009, 2010, 2011 and 2012 remain open to federal and state audit. As of July 31, 2012, management has evaluated the application of these standards to the Funds, and has determined that no provision for income tax is required in the Funds' financial statements for uncertain tax positions.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At July 31, 2012, the Funds had pre-enactment and post-enactment net capital losses for federal income tax purposes as shown in the following table. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to Fund shareholders. The Funds are subject to certain limitations, under U.S. tax rules, on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership.

In order to present paid-in capital 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, 2012, the adjustments for each Fund were as follows:

                                                                              Accumulated

E. EXPENSES:

Expenses that are directly related to one of the Funds are charged directly to the respective Fund, except for the First Trust Mid CapValue 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, for which expenses other than excluded expenses (discussed in Note 3) are paid by First Trust Advisors L.P. ("First Trust" or the "Advisor"). General expenses of the Trust are allocated to all the Funds based upon the net assets of each Fund.

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

F. ACCOUNTING PRONOUNCEMENTS:

In April 2011, the Financial Accounting Standards Board ("FASB") released Accounting Standards Update ("ASU") No. 2011-03, "Reconsideration of Effective Control for Repurchase Agreements." This ASU amends FASB Accounting Standards Codification ("ASC") Topic 860, "Transfers and Servicing"; specifically the criteria required to determine whether a repurchase agreement and similar agreements should be accounted for as sales of financial assets or secured borrowings with commitments. This ASU is effective for fiscal years and interim

periods beginning on or after December 15, 2011. Management has concluded that the adoption of ASU No. 2011-03 is not expected to have a material impact on the Funds' financial statements and the accompanying notes, net assets or results of operations.

In May 2011, FASB issued ASU No. 2011-04 "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs", modifying Topic 820, "Fair Value Measurements and Disclosures". At the same time, the International Accounting Standards Board ("IASB") issued International Financial Reporting Standard ("IFRS") 13, "Fair Value Measurement." The objective by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, the ASU requires reporting entities to disclose (i) the amounts of any transfers between Level 1 and Level 2, and the reasons for the transfers, (ii) for Level 3 fair value measurements, quantitative information about significant unobservable inputs used, (iii) a description of the valuation processes used by the reporting entity, and (iv) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of the ASU is for interim and annual periods beginning after December 15, 2011. Management is currently evaluating the impact of the updated standards on the Funds' financial statements, if any.

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. 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 other services necessary for the management of the Funds.

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 (such Funds, 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, 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 such 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 the Advisor 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, 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, 2013.

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

The advisory fee waivers and expense reimbursements for the year ended July 31, 2012 and the expenses borne by the Advisor subject to recovery from each Fund for the periods indicated were as follows:

                                                                           Expenses Borne by Advisor Subject to Recovery

5. CREATION, REDEMPTION & TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 50,000 shares. 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. Purchasers of 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
      101-200                    $1,000
      201-300                    $1,500
      301-400                    $2,000
      401-500                    $2,500
      501-600                    $3,000
      601-700                    $3,500

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 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.

Parties 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
      101-200                    $1,000
      201-300                    $1,500
      301-400                    $2,000
      401-500                    $2,500
      501-600                    $3,000
      601-700                    $3,500

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 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, the Funds will not pay 12b-1 fees before November 30, 2013.

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 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 "Fund"), including the portfolios of investments, as of July 31, 2012, 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 periods presented. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2012 by correspondence with the Fund's custodian and brokers; where replies were not received, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the funds listed above included in the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2012, 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 the each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

ADVISORY AGREEMENT

Board Considerations Regarding Approval of Investment Management Agreement

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

First Trust Large Cap Core AlphaDEX(R) Fund (FEX) First Trust Mid Cap Core AlphaDEX(R) Fund (FNX) First Trust Small Cap Core AlphaDEX(R) Fund (FYX) First Trust Multi Cap Growth AlphaDEX(R) Fund (FAD) First Trust Multi Cap Value AlphaDEX(R) Fund (FAB) First Trust Large Cap Growth AlphaDEX(R) Fund (FTC) First Trust Large Cap Value AlphaDEX(R) Fund (FTA)

The Board approved the continuation of the Agreement for a one-year period ending March 31, 2013, for each Fund at a meeting held on March 11-12, 2012. The Board of Trustees determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the services, expenses 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. To assist the Board in its evaluation of the Agreement for each Fund, the Independent Trustees received a report in advance of the Board meeting responding to a request for information from counsel to the Independent Trustees. The report, 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 for each Fund as compared to fees charged to a peer group of Funds compiled by Lipper Inc. ("Lipper"), an independent source (the "Lipper Expense Group"), and as compared to fees charged to other clients of the Advisor with similar investment objectives and to other exchange-traded funds ("ETFs") managed by the Advisor; expenses of each Fund compared to expense ratios of the funds in the Fund's Lipper Expense Group; 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; fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P.; and a summary of the Advisor's compliance program. Following receipt of this information, counsel to the Independent Trustees posed follow-up questions to the Advisor, and the Independent Trustees and their counsel then met separately to discuss the information provided by the Advisor, including the supplemental responses. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor is a reasonable business arrangement from each Fund's perspective as well as from the perspective of shareholders. 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 investment advisory fee. The Board also considered that the Agreement was approved by shareholders of each Fund at meetings held in December 2010.

In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of services provided 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 the services provided by the Advisor to the Funds. The Board also considered the background and experience of the persons responsible for the day-to-day management of the Funds. The Board considered the compliance program that had been developed by the Advisor and the procedures in place to monitor each Fund's investment program. In light of the information presented and the considerations made, the Board concluded that the nature, quality and extent of services provided to the Trust and each Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with its investment objective and policies.

The Board considered the advisory fees payable by each Fund under the Agreement. The Board considered that the Advisor agreed to extend the current expense cap for each Fund through November 30, 2013. For each Fund, the Board noted that expenses borne by the Advisor are to be subject to reimbursement by the Fund for up to three years from the date the fee or expense was incurred, but

Page 120


ADDITIONAL INFORMATION (CONTINUED)

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
STYLE FUNDS
JULY 31, 2012 (UNAUDITED)

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 by the Advisor. The Board considered the fees charged by the Advisor to other ETFs and other advisory clients with investment objectives and policies similar to the Funds', noting that those fees generally were similar to the fees charged to the Funds. In addition, the Board received data prepared by Lipper showing the management fees and expense ratios of each Fund as compared to the Fund's Lipper Expense Group. Because each Fund's Lipper Expense Group included peer funds that pay a unitary fee, the Board determined that the Funds' expense ratios were the more relevant data point. Based on the information provided, the Board noted that the total (net) expense ratio of each Fund was above the median of the Fund's Lipper Expense Group. The Board discussed with representatives of the Advisor the limitations in creating a relevant peer group for each Fund, including that (i) many of the Funds are unique in their composition, which makes assembling peers with similar strategies and asset mix difficult and (ii) Lipper omitted certain peer funds due to size that are otherwise logical and appropriate comparisons based on style, strategy and objective. The Board took these limitations into account in considering the Lipper data. The Board also considered information regarding First Trust ETFs from a February 2012 report from Cogent Research on ETF investors.

The Board considered performance information for each Fund, noting that the performance information included each Fund's quarterly performance report, which is part of the process that the Board has established for monitoring each Fund's performance on an ongoing basis. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board also considered information regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, the Fund's tracking error and the Fund's excess return as compared to a benchmark index. 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 error for each Fund was consistent with the target set forth in the Fund's prospectus. In addition, the Board received data prepared by Lipper comparing each Fund's performance to a peer group selected by Lipper (the "Lipper Performance Group") and to a broad-based benchmark. In reviewing each Fund's performance as compared to the performance of the Fund's Lipper Performance Group, the Board took into account the limitations described above with respect to creating relevant peer groups for the Funds.

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

The Board noted that the Advisor has continued to invest in personnel and infrastructure and considered whether fee levels reflect any economies of scale for the benefit of shareholders. The Board concluded that the advisory fee for each Fund reflects an appropriate level of sharing of any economies of scale at current asset levels. The Board also considered the costs of the services provided and profits realized by the Advisor from serving as investment advisor to each Fund for the twelve months ended December 31, 2011, as set forth in the materials provided to the Board. Based on the information provided, the Board concluded that the pre-tax profits estimated to have been realized by the Advisor in connection with the management of each Fund for calendar year 2011 were not unreasonable. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and First Trust Portfolios L.P. their exposure to investors and brokers who, in the absence of the Funds, may have had no dealings with the Advisor, 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 Trust and each Fund. No single factor was determinative in the Board's analysis.

RISK CONSIDERATIONS

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
STYLE FUNDS
JULY 31, 2012 (UNAUDITED)

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.

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

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

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

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

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

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

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

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

Each Fund is considered to be non-diversified. As a result, each Fund is exposed to additional market risk. A non-diversified fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, changes in the market value of a single portfolio security could cause greater fluctuations in share price than would occur in a diversified fund. Furthermore, non-diversified funds are more susceptible to any single political, regulatory or economic occurrence.

Each Fund is not actively managed. A Fund may be affected by a general decline in certain market segments relating to a Fund's corresponding index. A Fund invests in securities included in or representative of its corresponding index regardless of its investment merit. A Fund generally will not attempt to take defensive positions in declining markets.

RISK CONSIDERATIONS (CONTINUED)

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
STYLE FUNDS
JULY 31, 2012 (UNAUDITED)

The First Trust Multi Cap Value AlphaDEX(R) Fund, the First Trust Multi Cap Growth AlphaDEX(R) Fund, the First Trust Mid Cap Core AlphaDEX(R) Fund, the First Trust Small Cap Core AlphaDEX(R) Fund, the First Trust Mid Cap Value AlphaDEX(R) Fund, the First Trust Mid Cap Growth AlphaDEX(R) Fund, the First Trust Small Cap Value AlphaDEX(R) Fund and the First Trust Small Cap Growth AlphaDEX(R) Fund may invest in small capitalization and/or mid capitalization companies. Such 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.

The First Trust Large Cap Value AlphaDEX(R) Fund and the First Trust Multi Cap Value AlphaDEX(R) Fund invest with a value-oriented investment style and may not be successful in realizing their respective investment objectives. Value companies may have experienced adverse business developments or may be subject to special risks that cause their securities to be out of favor, may never reach what may be their full value or may go down in price.

The First Trust Large Cap Growth AlphaDEX(R) Fund and the First Trust Multi Cap Growth AlphaDEX(R) Fund invest with a growth-oriented investment style and may not be successful in realizing their respective investment objectives. Securities of growth companies may experience significant fluctuations in price in response to economic, political, regulatory, company specific, sector or market developments, changes in perceptions or interest rate changes.

Each of the First Trust Large Cap Core AlphaDEX(R) Fund, the First Trust Mid Cap Core AlphaDEX(R) Fund, the First Trust Small Cap Core AlphaDEX(R) Fund, the First Trust Large Cap Value AlphaDEX(R) Fund, the First Trust Large Cap Growth AlphaDEX(R) Fund, the First Trust Mid Cap Value AlphaDEX(R) Fund, the First Trust Mid Cap Growth AlphaDEX(R) Fund, the First Trust Small Cap Value AlphaDEX(R) Fund, the First Trust Small Cap Growth AlphaDEX(R) Fund and the First Trust Mega Cap AlphaDEX(R) Fund normally invests at least 90% of its assets in common stocks that comprise the Index upon which it is based. The securities of companies represented in the Index upon which each Fund is based generally have market capitalizations that are consistent with the name of the Index. For purposes of determining the market capitalization range of such securities, the Fund will use the current range of the Index upon which it is based. However, the Fund will not be forced to sell a stock because the stock has exceeded or fallen below the current market capitalization range of the Index. Because of market movement, there can be no assurance that the securities in a Fund will stay within a given market capitalization range. As a result, each Fund may be exposed to additional risk or may not give investors the opportunity to invest fully in a given market capitalization range.

Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of a Fund's assets can decline as can the value of a Fund's distributions. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

The Funds may invest in non-U.S. securities publicly traded in the United States. Securities issued by non-U.S. companies present risks beyond those of securities of U.S. issuers. Risks of investing in non-U.S. securities include:
different accounting standards; expropriation, nationalization or other adverse political or economic developments; currency devaluation, blockages or transfer restrictions; changes in non-U.S. currency exchange rates; taxes; restrictions on non-U.S. investments and exchange of securities; and less government supervision and regulation of issuers in non-U.S. countries. Prices of non-U.S. securities also may be more volatile.

NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE

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 2010 were $66,000 for the registrant, $36,000 for the registrant's investment adviser and $37,300 for the registrant's distributor, and for 2011 were $60,242.86 for the registrant, $3,720 for the registrant's investment adviser and $35,433 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.
