Mid-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and the value of securities issued by these companies may move sharply.

An underlying strategy’s investments in growth stocks can be volatile. Growth companies usually invest a high portion of earnings in their businesses and may lack the dividends of value stocks that may cushion declining stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically. Growth stocks may also be more expensive relative to their earnings or assets compared to value or other stocks.

• Investors in ETFs should consider carefully information contained in the prospectus, including investment objectives, risks, charges and expenses. You can view, download, and print a prospectus by selecting the "View Prospectus" link at the top of the page. If there are remaining questions, please call 1-800-435-4000. Please read the prospectus carefully before investing.
• Unlike mutual funds, shares of ETFs are not individually redeemable directly with the ETF. Shares are bought and sold at market price, which may be higher or lower than the net asset value (NAV).
• Market Price is the price at which investors buy and sell ETF shares in the stock market. ETF Market Price determines investor returns. An ETF’s Market Price may be higher or lower than the NAV at any given point in time. Market price returns are based upon the Official Closing Price of the primary listing exchange (generally, 4:00 p.m. Eastern time) and may not represent the returns you would receive if shares were traded at other times.
• NAV (Net Asset Value) is a per share valuation of the securities in an ETF officially calculated once per day. NAV price performance is primarily used to evaluate the fund and its managers and may not reflect the actual return for the investor.

• Morningstar proprietary ratings reflect historical risk-adjusted performance. For each fund with at least a 3-year history, Morningstar calculates a Morningstar Rating™ based on a Morningstar risk-adjusted return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. (Each share class is counted as a fraction of 1 fund within this scale and rated separately, which may cause slight variations in the distribution percentages). The top 10% of the funds in an investment category receive 5 stars, 22.5% receive 4 stars, 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star.
