Principal Investment Strategies

• Normally investing in municipal money market securities.

• Normally investing at least 80% of assets in municipal securities whose interest is exempt from federal and Massachusetts personal income taxes.

• Potentially investing up to 20% of assets in municipal securities whose interest is subject to Massachusetts personal income tax.

• Normally not investing in municipal securities whose interest is subject to the federal alternative minimum tax.

• Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.

• Investing in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, liquidity, and diversification of investments.

Principal Investment Risks

• Municipal Market Volatility. The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.

• Interest Rate Changes. Interest rate increases can cause the price of a money market security to decrease.

• Foreign Exposure. Entities providing credit support or a maturity-shortening structure that are located in foreign countries can be affected by adverse political, regulatory, market, or economic developments in those countries.

• Geographic Concentration. Unfavorable political or economic conditions within Massachusetts can affect the credit quality of issuers located in that state.

• Issuer-Specific Changes. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a money market security to decrease.

You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Fidelity Investments and its affiliates, the fund’s sponsor, have 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.
