Large-cap companies are generally more mature and the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

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.

Active semi-transparent (also known as non-transparent) ETFs operate differently from other exchange-traded funds (ETFs). Unlike other ETFs, an active semi-transparent ETF does not publicly disclose its entire portfolio composition each business day, which may affect the price at which shares of the ETF trade in the secondary market. To find out more about active semi-transparent ETFs, please read Active Semi-transparent ETFs: What you need to know.

• 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).

• 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.
