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 income tax.
Municipal money market securities are high-quality, short-term debt securities that pay a fixed, variable, or floating interest rate, and include variable rate demand notes, commercial paper, and municipal notes. Municipal securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility.
  • Normally not investing in municipal securities whose interest is subject to the federal alternative minimum tax.
  • Potentially investing up to 20% of assets in securities subject to state and/or federal income 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.
  • Income Risk.
A low or negative interest rate environment can adversely affect the fund's yield.
  • 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.
  • Issuer-Specific Changes.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) 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. An investment in the fund is not a bank account and 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, is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.

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 income tax.
Municipal money market securities are high-quality, short-term debt securities that pay a fixed, variable, or floating interest rate, and include variable rate demand notes, commercial paper, and municipal notes. Municipal securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility.
  • Normally not investing in municipal securities whose interest is subject to the federal alternative minimum tax.
  • Potentially investing up to 20% of assets in securities subject to state and/or federal income 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.
  • Income Risk.
A low or negative interest rate environment can adversely affect the fund's yield.
  • 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.
  • Issuer-Specific Changes.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) 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. An investment in the fund is not a bank account and 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, is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.
