The prospectus or summary prospectus should be read carefully before investing. ETF Characteristics The fund lists and principally trades its shares on the NYSE Arca, Inc. The fund’s return may not match the return of the StrataQuant® Consumer Staples 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. 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. The success of consumer staples companies which provide products that are typically considered non-discretionary items based on consumer purchasing habits is affected by a variety of factors, such as government regulations, which may affect the permissibility of using various food additives and the production methods of companies that manufacture food products. The fund is classified as “non-diversified” and may invest a relatively high percentage of its assets in a limited number of issuers.

As a result, the fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers. 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. Definitions Standard Deviation is a measure of price variability (risk). Alpha is an indication of how much an investment outperforms or underperforms on a risk-adjusted basis relative to its benchmark. Beta is a measure of price variability relative to the market.

Sharpe Ratio is a measure of excess reward per unit of volatility. Correlation is a measure of the similarity of performance. The Russell 1000® Index is an unmanaged index used to measure the large-cap U.S.

Ratings are based on the ETF’s Morningstar Risk-Adjusted Return measure which accounts for variation in monthly performance, placing more emphasis on downward variations and rewarding consistent performance.

An ETF’s risk-adjusted return includes a brokerage commission estimate. This estimate is intended to reflect what an average investor would pay when buying or selling an ETF. PLEASE NOTE, this estimate is subject to change and the actual brokerage commission an investor pays may be higher or lower than this estimate.

Morningstar compares each ETF’s risk-adjusted return to the open-end mutual fund rating breakpoints for that category. Consistent with the open-end mutual fund ratings, the top 10% of ETFs in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. The overall rating for an ETF is based on a weighted average of the time-period ratings (e.g., the ETF’s 3, 5, and 10 year rating).

The determination of an ETF’s rating does not affect the retail open end mutual fund data published by Morningstar. ©2016 Morningstar, Inc. All Rights Reserved.
