Fidelity New Jersey Municipal Money Market Fund (FNJXX) is a municipal money market mutual fund that seeks as high a level of current income, exempt from federal income tax and New Jersey personal income tax, as is consistent with the preservation of capital. The fund, part of Fidelity Court Street Trust II and managed by Fidelity Management & Research Company (FMRCo), normally invests at least 80% of assets in high-quality, short-term municipal securities issued by or on behalf of New Jersey or U.S. territories whose interest is exempt from federal income tax (and typically New Jersey personal income tax); these include municipal notes, variable and floating-rate securities, general obligation bonds, revenue bonds, and participation certificates; the fund may also invest up to 20% of assets in taxable instruments or municipal securities subject to New Jersey personal income tax, as well as repurchase agreements and shares of other affiliated money market funds. It maintains a stable $1.00 net asset value, targets high liquidity for institutional and retail investors (with a $25,000 minimum investment for premium class shares), and features an expense ratio of approximately 0.30%, focusing on preservation of capital and daily liquidity for New Jersey tax-sensitive investors, financial intermediaries, and cash management needs in the municipal fixed-income segment.
Established in 1990 and headquartered in Boston, Massachusetts as part of Fidelity Investments' extensive lineup of over 400 mutual funds, the fund primarily serves investors in New Jersey and surrounding regions seeking tax-advantaged cash equivalents amid fluctuating short-term interest rates.
No major strategic changes, such as acquisitions, partnerships, funding rounds, new product launches, or reorganizations, have been reported for FNJXX within the last 1-2 years; the fund continues stable operations under Fidelity's oversight, with portfolio adjustments reflecting ongoing municipal market conditions and regulatory compliance for money market funds.
