Fund Summary

Investment Objective/Strategy - The First Trust Cloud Computing ETF is an exchange-traded fund. The investment 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 ISE Cloud Computing Index.

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

The index is a modified equal dollar weighted index designed to track the performance of companies actively involved in the cloud computing industry. To be included in the index, a security must be engaged in a business activity supporting or utilizing the cloud computing space, listed on an index-eligible global stock exchange and have a market capitalization of at least $100 million.
All securities are then classified according to the following three business segments:
- Pure Play Cloud Computing Companies: Companies that are direct service providers for “the cloud” (network hardware/software, storage, cloud computing services) or companies that deliver goods and services that utilize cloud computing technology.
- Non Pure Play Cloud Computing Companies: Companies that focus outside the cloud computing space but provide goods and services in support of the cloud computing space.
- Technology Conglomerate Cloud Computing Companies: Large broad-based companies that indirectly utilize or support the use of cloud computing technology.
The overall weight for each of the three business segments is calculated as follows:
- 10% of the index weight is allocated to technology conglomerate companies.
- The index weight that is allocated to non pure play companies is calculated by dividing the non pure play companies' market capitalization by the sum of the pure play and non pure play market capitalizations.
- The remainder of the index weight is allocated to pure play companies.
Stocks are equally weighted within each of the three classifications.
The index is reconstituted and rebalanced semi-annually.

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.

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	12-Month Distribution Rate is calculated by dividing the sum of the fund's trailing 12-month ordinary distributions paid or declared by the NAV price. Distribution rates may vary.
⁶	Index yield represents the weighted average trailing 12-month dividend of the constituents of the ISE Cloud Computing(TM) Index.
⁷	All market capitalization numbers are in USD$ Millions.
⁸	Inception Date is 7/5/2011

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 ISE Cloud Computing™ 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.

An investment in a fund containing securities of non-U.S. issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers.

The fund may invest in depositary receipts which may be less liquid than the underlying shares in their primary trading market.

The fund invests in information technology companies, which are subject to certain risks, including 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. Certain companies may be smaller and less experienced companies, with limited product lines, markets or financial resources. Information technology company stocks, especially those which are Internet related, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance.

The risks related to investing in cloud computing companies include interruptions or delays in service, security breaches involving sensitive, proprietary and confidential information, privacy concerns and laws, and other regulations that may limit or otherwise affect the operations of such companies.

Changes in currency exchange rates and the relative value of non-US currencies may affect the value of a fund's investments and the value of a fund's shares.

First Trust Advisors L.P. is the adviser to the fund. First Trust Advisors L.P. is an affiliate of First Trust Portfolios L.P., the fund's distributor.
