About OWMBX

Old Westbury Municipal Bond Fund is an open-end mutual fund focused on U.S. municipal securities within the muni national intermediate category. Its primary objective is to provide income that is generally exempt from federal income tax by investing predominantly in bonds issued by state and local governments to finance public projects such as infrastructure, education, and transportation. According to category definitions, portfolios in this segment typically maintain durations around four to six years to balance interest-rate sensitivity with income generation, and diversify across multiple states and sectors to manage credit risk. The fund maintains a broad portfolio with hundreds of holdings, limiting concentration—its top 10 positions represent a single-digit share of assets—while keeping cash and high-quality liquidity instruments as part of its allocation. With multi-manager oversight and an expense ratio positioned around the middle of peers, the fund targets consistent, tax-advantaged income within a diversified municipal bond framework. Its role in the market is to serve investors seeking federally tax-exempt income and intermediate-rate interest exposure through a nationally diversified municipal bond strategy.
