California Insured Tax-Free seeks safety of principal and high current income that is exempt from federal and California income taxes through investment in insured California municipal securities.
The fund managers buy long-term insured debt securities with interest payments exempt from federal and California income taxes. Cities, counties and other municipalities in California usually issue these securities for public projects.
The fund's investments are insured. This is significant because
A debt security's insurance cannot be cancelled and it guarantees that interest and other payments will be made as scheduled.
The weighted average maturity of the fund is expected to be 10 years or longer.
The fund also may use futures contracts and options to pursue its investment objective.
During unusual market conditions, the fund is permitted to keep a significant amount of its assets in cash or cash-equivalents. If it does, it may not achieve its investment objective and may generate taxable income.
Additional information about California Insured Tax-Free's investments is available in its annual and semiannual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period. You may get these reports at no cost by calling us.
In summary, California Insured Tax-Free is intended for investors who seek safety of principal and high current income that is exempt from federal and California income taxes through a municipal securities fund, and who are willing to accept the risks associated with the fund's investment strategy.

California High-Yield Municipal seeks high current income that is exempt from federal and California income taxes.
The fund managers buy long- and intermediate-term debt securities with interest payments exempt from federal and California income taxes. Cities, counties and other municipalities in the 50 states and U.S. territories usually issue these securities for public projects.
The fund managers also may buy long- and intermediate-term debt securities whose interest payments are exempt from regular federal and California income taxes, but not the federal alternative minimum tax. Cities, counties and other municipalities in California usually issue these securities (called private activity bonds) to fund for-profit private projects, such as athletic stadiums, airports and apartment buildings. Between 10% and 30% of the fund's total assets may be invested in these securities.
The fund managers buy securities rated below investment-grade, including so-called junk bonds and bonds that are in technical or monetary default. Issuers of these securities often have short financial histories, questionable credit, or problems making interest and principal payments.
During unusual market conditions, the fund is permitted to keep a significant amount of its assets in cash or cash-equivalents. If it does, it may not achieve its investment objective and may generate taxable income.
Additional information about California High-Yield Municipal's investments is available in its annual and semi-annual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period.
