About BBMUX

Bridge Builder Municipal Bond Fund is an open-end mutual fund that invests primarily in U.S. municipal securities to deliver current income that is exempt from federal income tax, with a secondary objective of preserving capital. Under normal conditions, it allocates at least 80% of net assets to municipal bonds across a range of maturities, emphasizing diversified exposure to state and local issuers that finance public projects such as transportation, utilities, education, and healthcare. The fund resides in the Muni National Intermediate category, reflecting a balanced interest-rate profile and moderate duration positioning designed to manage rate sensitivity while maintaining tax-advantaged income. Key characteristics include a broad portfolio spanning thousands of holdings and a low expense ratio relative to peers, supporting cost-efficient access to the municipal market. Regular monthly distributions underscore its income orientation, while the portfolio’s credit and duration management aims to balance income generation with risk control in changing market conditions. By aggregating investment across numerous issuers and sectors, the fund serves as a diversified core municipal allocation for investors seeking federally tax-exempt income.
