Performance Narrative [Text Block]

The bar chart below shows how the fund’s investment results have varied from year to year, and the following table shows how the

fund’s average annual total returns for various periods compared to that of one or more indices. The MSCI ACWI Index (Net) serves as the fund’s regulatory index and provides a broad measure of market performance. The FTSE EPRA Nareit Global Index (Net) is the fund’s additional index and is more representative of the fund’s investment universe than the regulatory index. This information provides some indication of the risks of investing in the fund. All figures assume distributions were reinvested. Keep in mind that future performance (both before and after taxes) may differ from past performance. For current performance information, please see www.schwabassetmanagement.com/prospectus.

Performance Table Explanation after Tax Higher In some cases, the return after taxes on distributions and sale of shares may exceed the fund’s other returns due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.
