Investors should consider carefully information contained in the prospectus, including investment objectives, risks, charges and expenses. You can request a prospectus by calling 800-435-4000. Please read the prospectus carefully before investing.  Investment value will fluctuate, and shares, when redeemed, may be worth more or less than original cost.

There are risks associated with investing in foreign markets, such as erratic market conditions, economic and political instability, and fluctuations in currency and exchange rates. Risks of the REITs are similar to those associated with direct ownership of real estate, such as changes in real estate values and property taxes, interest rates, cash flow of underlying real estate assets, supply and demand, and the management skill and creditworthiness of the issuer. Diversification strategies do not ensure a profit and do not protect against losses in declining markets.

1. Schwab and the investment adviser have agreed to limit the fund's "net operating expenses" as stated in the prospectus for each fund, for so long as the investment adviser serves as the adviser to the fund. This agreement may only be amended or terminated with the approval of the fund's Board of Trustees. The limitation excludes interest, taxes, expenses for dividends and interest paid on securities sold short, and certain non-routine expenses, which may result in a fund incurring net operating expenses above the limitation.
