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.

Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid-and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, an underlying fund’s performance could be impacted.

Small-cap funds are subject to greater volatility than those in other asset categories.

• 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.
