A sector fund focuses on companies in a specific sector and may involve a greater degree of risk than an investment in funds with broader diversification.

Exchange-Traded Notes (ETNs) are distinct from Exchange-Traded Funds (ETFs). ETNs are debt instruments backed by the credit of the issuer and carry inherent credit risk. In some instances, ETNs can be subject to early redemption prior to maturity at the issuer’s discretion. Therefore, their value when called may be less than the market price that you paid or even zero, resulting in a partial, or total, loss of your investment. ETNs are not generally appropriate for the average investor. To find out more about ETNs, please read Exchange-Traded Notes: The facts and the risks.

• 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.
