The performance data shown represent past performance, which is not a guarantee of future results. Investment returns and principal value will fluctuate so that investors' shares, when sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data cited.

Performance data do not reflect the deduction of the $25 annual account service fee that may be applied to certain accounts. If this fee was included, performance would be lower.

Total returns: Short-term total return information is provided only as a service. Historical performance—particularly short-term performance—is no guarantee of future returns. Price, yield, and return on an actual investment will fluctuate, and you may have a gain or loss when you sell. Average annual returns include changes in price and reinvestments of dividends and capital gains. Since-inception returns for less than 1 year and year-to-date returns aren't annualized. Index performance is provided as a benchmark but isn't illustrative of any particular investment. You can't invest in an index.

Standardized returns: To see quarterly fee-adjusted returns, refer to the Price & Performance details.

Expense ratios: Expense ratios are displayed on Overview. For investments that are less than 1 fiscal year old, expense ratios are estimated.

Risk: All investing is subject to risk, including the possible loss of the money you invest. Funds that concentrate on a relatively narrow market sector face the risk of higher share-price volatility. Investments in stocks or bonds issued by non-U.S. companies are subject to risks including country/regional risk and currency risk.
