with the cost of investing in other mutual funds. The Example assumes that you

invest $10,000 in the fund for the time periods indicated and then redeem all of

your shares at the end of those periods. The Example also assumes that your

investment has a 5% return each year and that the fund's operating expenses

remain the same. Although your actual costs may be higher or lower, based on

these assumptions your costs would be:

Principal Investment Strategy

As a money market fund, the fund is subject to maturity, quality, liquidity and

diversification requirements designed to help it maintain a stable share price

of $1.00. To pursue its goal, the fund normally invests substantially all of its

assets in short-term, high quality municipal obligations that provide income

exempt from federal and California state income taxes. The fund also may invest

in high quality short-term structured notes, which are derivative instruments

whose value is tied to underlying municipal obligations.



Although the fund seeks to provide income exempt from federal and California

state income taxes, interest from some of the fund's holdings may be subject to

the federal alternative minimum tax. In addition, the fund temporarily may

invest in high quality, taxable money market instruments and/or municipal

obligations that pay income exempt only from federal income tax, including when

the portfolio manager believes acceptable California municipal obligations are

not available for investment.

Principal Risks

An investment in the fund is not insured or guaranteed by the Federal Deposit

Insurance Corporation (FDIC) or any other government agency. Although the fund

seeks to preserve the value of your investment at $1.00 per share, it is

possible to lose money by investing in the fund.



The fund's yield will fluctuate as the short-term securities in its portfolio

mature and the proceeds are reinvested in securities with different interest

rates. Additionally, while the fund has maintained a constant share price since

inception, and will continue to try to do so, neither The Dreyfus Corporation

nor its affiliates are required to make a capital infusion, enter into a capital

support agreement or take other actions to prevent the fund's share price from

falling below $1.00. The following are the principal risks that could reduce the

fund's income level and/or share price:



o Interest rate risk. This risk refers to the decline in the prices of

  fixed-income securities that may accompany a rise in the overall level of

  interest rates. A sharp and unexpected rise in interest rates could cause a

  money market fund's share price to drop below a dollar.



o Credit risk. Failure of an issuer to make timely interest or principal

  payments, or a decline or perception of a decline in the credit quality of a

  security, can cause the security's price to fall, potentially lowering the

  fund's share price. The credit quality of the securities held by the fund can

  change rapidly in certain market environments, and the default of a single

  holding could have the potential to cause significant deterioration of the

  fund's net asset value.



o Liquidity risk. When there is little or no active trading market for specific

  types of securities, it can become more difficult to sell the securities at or

  near their perceived value. In such a market, the value of such securities may

  fall dramatically, potentially lowering the fund's share price, even during

  periods of declining interest rates. Also, during such periods, redemptions by a

  few large investors in the fund may have a significant adverse effect on the

  fund's net asset value and remaining fund shareholders.



o Tax risk. To be tax-exempt, municipal obligations generally must meet certain

  regulatory requirements. If any such municipal obligation fails to meet these

  regulatory requirements, the interest received by the fund from its investment

  in such obligations and distributed to fund shareholders will be taxable.



o Structured notes risk. Structured notes, a type of derivative instrument, can

  be volatile, and the possibility of default by the financial institution or

  counterparty may be greater for these instruments than for other types of money

  market instruments. Structured notes typically are purchased in privately

  negotiated transactions from financial institutions and, thus, an active trading

  market for such instruments may not exist.



o State-specific risk. The fund is subject to the risk that California's

  economy, and the revenues underlying its municipal obligations, may decline.

  Investing primarily in a single state makes the fund more sensitive to risks

  specific to the state and may magnify other risks.



o Non-diversification risk. The fund is non-diversified, which means that the

  fund may invest a relatively high percentage of its assets in a limited number

  of issuers. Therefore, the fund's performance may be more vulnerable to changes

  in the market value of a single issuer or group of issuers and more susceptible

  to risks associated with a single economic, political or regulatory occurrence

  than a diversified fund.
