About MFNLX

BlackRock National Municipal Fund Investor C Shares is an open-end municipal bond mutual fund focused on generating federally tax-exempt income. It primarily invests in a diversified portfolio of U.S. municipal bonds, with a policy to keep at least 80% of assets in municipals and a stated intent to hold a majority in investment‑grade issues, while retaining flexibility to allocate to lower-rated debt when warranted by the mandate. The strategy emphasizes intermediate and longer maturities, providing exposure to interest rate dynamics and credit conditions across state and local issuers, including general obligation and revenue-backed bonds that finance infrastructure, transportation, utilities, and essential public services. Managed within BlackRock’s municipal platform, the fund distributes income monthly and maintains a broad holdings base. Its long track record reflects a role as a core national muni allocation for investors seeking diversified tax-advantaged income and professional credit selection across sectors and geographies. Key characteristics typically disclosed for this share class include an ongoing expense ratio, moderate portfolio turnover, and a minimum initial investment appropriate for individual accounts.
