An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.Because the fund invests primarily in California municipal securities and securities issued by U.S. territories, its yield and share price will be affected by political and economic developments within the state and territories.

Specifically, the portfolio managers are permitted at any time to invest up to 20% of the fund's assets in debt securities with interest payments that are subject to federal income tax and/or federal AMT.
