Fund Summary

Investment Objective/Strategy - The First Trust Total US Market AlphaDEX® ETF is an exchange-traded index fund. The objective of the Fund is to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the NASDAQ AlphaDEX® Total US Market Index.

There can be no assurance that the Fund's investment objectives will be achieved.

The NASDAQ AlphaDEX^® Total US Market Index is an "enhanced" index created and administered by Nasdaq, Inc. ("Nasdaq") which employs the AlphaDEX^® stock selection methodology to select stocks that meet certain criteria from three indices - the NASDAQ US Large Cap Index, the NASDAQ US Mid Cap Index and the NASDAQ US Small Cap Index.
Nasdaq constructs the NASDAQ AlphaDEX^® Total US Market Index by ranking the eligible stocks within the three indices on growth factors including 3-, 6- and 12- month price appreciation, sales to price and one year sales growth, and separately on value factors including book value to price, cash flow to price and return on assets. All stocks are ranked within each size class (Large, Mid, or Small) on the sum of ranks for the growth factors and, separately, all stocks are ranked on the sum of ranks for the value factors. A stock must have data for all growth and/or value factors to receive a rank for that style.
Nasdaq classifies each stock as either a value stock or a growth stock and each stock receives its style rank from the previous step as its selection score.
The top 200 stocks from the NASDAQ US Large Cap Index (50% of the total portfolio), the top 400 stocks from the NASDAQ US Mid Cap Index (30% of the total portfolio) and the top 600 stocks from the NASDAQ US Small Cap Index (20% of the total portfolio) based on the selection score determined in the previous step comprise the "selected stocks".
The selected stocks are divided into quintiles within their size class based on their rankings and the top ranked quintiles receive a higher weight within each sub-portfolio (Large, Mid, and Small). Within each sub-portfolio, stocks are equally weighted within each quintile.
The index is reconstituted and rebalanced quarterly.

*Performance data quoted represents past performance. Past performance is not a guarantee of future results and current performance may be higher or lower than performance quoted. Investment returns and principal value will fluctuate and shares when sold or redeemed, may be worth more or less than their original cost.

After Tax Held returns represent return after taxes on distributions. Assumes shares have not been sold. After Tax Sold returns represent the return after taxes on distributions and the sale of fund shares. Returns do not represent the returns you would receive if you traded shares at other times. Market Price returns are based on the midpoint of the bid/ask spread 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. Returns are average annualized total returns, except those for periods of less than one year, which are cumulative. The fund's performance reflects fee waivers and expense reimbursements, absent which performance would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

Footnotes

¹	The NAV represents the fund's net assets (assets less liabilities) divided by the fund's outstanding shares .
²	Fund shares are purchased and sold on an exchange at their share price rather than net asset value (NAV), which may cause the shares to trade at a price greater than NAV (premium) or less than NAV (discount).
³	Most recent distribution paid or declared to today's date. Subject to change in the future. There is no guarantee that the fund will declare dividends.
⁴	The 30-day SEC yield is calculated by dividing the net investment income per share earned during the most recent 30-day period by the maximum offering price per share on the last day of the period and includes the effects of fee waivers and expense reimbursements, if applicable.
⁵	The unsubsidized 30-day SEC yield is calculated the same as the 30-day SEC yield, however it excludes contractual fee waivers and expense reimbursements.

ETF Characteristics

The fund lists and principally trades its shares on The Nasdaq Stock Market LLC.

The fund's return may not match the return of the NASDAQ AlphaDEX® Total US Market Index. Securities held by the fund will generally not be bought or sold in response to market fluctuations.

Investors buying or selling fund shares on the secondary market may incur customary brokerage commissions. Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be redeemed directly from the fund by authorized participants, in very large creation/redemption units. If the fund's authorized participants are unable to proceed with creation/redemption orders and no other authorized participant is able to step forward to create or redeem, fund shares may trade at a discount to the fund's net asset value and possibly face delisting.

Risk Considerations

The fund's shares will change in value, and you could lose money by investing in the fund. One of the principal risks of investing in the fund is market risk. Market risk is the risk that a particular stock owned by the fund, fund shares or stocks in general may fall in value. There can be no assurance that the fund's investment objective will be achieved.

The fund may invest in small capitalization and mid capitalization companies. Such companies may experience greater price volatility than larger, more established companies.
