Fidelity Municipal Money Market Fund (FTEXX) is a municipal money market mutual fund managed by Fidelity Investments that seeks as high a level of current interest income exempt from federal income tax as is consistent with the preservation of capital and liquidity. The fund invests at least 80% of its assets in high-quality, short-term municipal securities whose interest is exempt from federal income tax, including variable and floating rate securities, municipal repurchase agreements, and tender option bonds; it may invest more than 25% of total assets in municipal securities financing similar projects such as hospitals or airports, while complying with industry-standard money market fund regulations for maturity, liquidity, quality, and diversification.
Headquartered in Boston, Massachusetts, the fund operates as part of Fidelity Union Street Trust II and primarily serves retail and institutional investors seeking tax-exempt cash management solutions across the United States.
Inception in 1980, FTEXX maintains a stable $1.00 net asset value with a total expense ratio of 0.41%, featuring low weighted average maturities typically measured in days.
