/sd/customer/portfolio_json 1.800.345.2021

Goal and Strategy

Total return and current income that is exempt from federal and CA income taxes through investment-grade, long-term municipal bonds.

Distinguishing Characteristics

Seeks to provide monthly California state and federal tax-free income while avoiding Alternative Minimum Tax (AMT) exposure.

A Note About Risk

The lower-rated securities in which the fund invests are subject to greater default and liquidity risk, because the issuers of high-yield securities are more sensitive to real or perceived economic changes. Interest rate changes are among the most significant factors affecting bond return. Generally, as interest rates rise, the value of the securities held in the fund will decline. The opposite is true when interest rates decline. Investment income may be subject to certain state and local taxes and, depending on your tax status, the federal alternative minimum tax (AMT). Capital gains are not exempt from state and federal income tax. There is no guarantee that the investment objectives will be met. Dividends and yields represent past performance and there is no guarantee that they will continue to be paid.


Rating & Rankings

Loading Ratings and Rankings ...

For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Morningstar ratings are based upon Investor class of shares, unless otherwise indicated. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Overall Morningstar RatingTM for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar RatingTM metrics. Past performance is no guarantee of future results.

Fund Management

Data reflects past performance for Investor Class shares, assumes reinvestment of dividends and capital gains and is no guarantee of future results. Current performance may be higher or lower than data shown. Investment return and principal value fluctuates. Redemption value may be more or less than original cost. Obtain performance data current to the most recent month end. For additional share class information, consult the prospectus.

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.

There is no guarantee that all of the fund's income will be exempt from federal or state or local income taxes. The portfolio managers are permitted to invest up to 20% of the fund's assets in debt securities with interest payments that are subject to federal income tax, California state or local income tax and/or the federal alternative minimum tax.

This fund is not available in all states.
