There is no assurance that a mutual fund will achieve its investment objective. Funds are subject to market risk, which is the possibility that the market values of securities owned by the fund will decline and that the value of fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in this fund. Please be aware that this fund may be subject to certain additional risks. Fixed-income securities. Subject to credit and interest-rate risk. Credit risk refers to the ability of an issuer to make timely payments of interest and principal. Interest-rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. In a declining interest-rate environment, the portfolio may generate less income. In a rising interest-rate environment, bond prices fall. Geographic concentration. The fund is more susceptible to political, economic, regulatory, or other factors affecting issuers of California securities than a fund that does not limit its investments to such issuers. Tax treatment. The fund may invest a portion of its total assets in bonds that may subject certain investors to the federal Alternative Minimum Tax (AMT). You should consult your tax advisor for further information on tax implications.
