Strategy. To pursue its goal, the fund aims to provide diversification across major asset classes, including domestic equity securities, international equity securities, real assets, fixed income securities and money market investments, as well as diversification across a range of sub-asset classes within the major asset classes. The fund gains exposure to these asset classes by primarily investing in affiliated exchange-traded funds (ETFs) from Schwab Funds (the Schwab ETFs). The fund may also invest in affiliated mutual funds from Schwab Funds and unaffiliated third-party ETFs and mutual funds (all such ETFs and mutual funds referred to as underlying funds).

The fund gains exposure to these asset classes by primarily investing in affiliated exchange-traded funds (ETFs) from Schwab Funds (the Schwab ETFs). The fund may also invest in affiliated mutual funds from Schwab Funds and unaffiliated third-party ETFs and mutual funds (all such ETFs and mutual funds referred to as underlying funds). The fund will generally invest in a Schwab ETF that, in the investment advisers opinion, corresponds to a sub-asset class and is competitive with unaffiliated third-party ETFs. The fund normally will invest, including its investments in the underlying funds, at least 25% of its assets in equity securities and at least 25% of its assets in fixed-income securities, which may include bonds, cash equivalents, money market funds and money market investments. As of the date of this prospectus, the funds target asset class allocation ranges are 38-68% in fixed-income securities, and 32-62% in equity securities. Each underlying fund may invest directly in equity, fixed income or other securities or investments, as appropriate, consistent with its investment objective, strategies and policies. Through its investments in underlying funds that invest in equity securities, the fund invests principally in large-cap stocks of U.S. and international developed-market countries, small-cap stocks of U.S. companies and stocks of emerging countries. The fund also invests in underlying funds that invest in fixed-income investments, principally treasury bonds, corporate bonds and securitized bonds, which are primarily of investment grade. The funds investments in underlying funds that seek exposure to real assets include funds that invest in real estate investment trusts (REITs) and other companies related to the real estate industry. The fund may also invest in underlying funds that seek exposure to commodities. Finally, the fund may invest in money market investments, primarily through underlying funds that are money market funds. The investment adviser has discretion to select the underlying fund investments and adjust the funds underlying fund allocations within a particular asset class based on the following considerations: market trends, its outlook for a given market capitalization and sub-asset class, and the underlying funds performance in various market conditions. The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in securities represented in the major asset classes noted above. The fund may invest in derivatives, primarily to seek returns on the funds otherwise uninvested cash assets. By using these instruments, the fund potentially can offset the impact on its performance of keeping some assets in cash. For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the fund may hold a significant amount of its assets in cash, money market instruments, repurchase agreements and other short-term obligations. When the fund engages in such activities, it may not achieve its investment objective. The fund also may lend portfolio securities to earn additional income. Any income realized through securities lending may help fund performance. Show less
