Eaton Vance Municipal Bond Fund (NYSE American: EIM) is a diversified, closed-end management investment company that seeks to provide current income exempt from regular federal income tax by investing primarily in a portfolio of municipal obligations. The Fund maintains a policy to invest at least 80% of its net assets in such municipal bonds, with an expectation to be fully invested at least 95% of its assets, including up to 20% in obligations rated BBB/Baa or lower (not more than 15% below B or equivalent); its portfolio emphasizes high-grade securities in sectors such as transportation, water and sewer, electric utilities, general obligation bonds, hospital, and power sectors. Eaton Vance Municipal Bond Fund pays common shareholders a stable monthly distribution, which may consist of ordinary dividends, capital gains, and return of capital, and employs leverage through residual interest bond (RIB) financing, auction preferred shares (APS), and interval municipal term preferred shares (iMTP) to enhance income potential.
Launched in 2002 and based in Boston, Massachusetts, at One Post Office Square, the Fund is managed by Eaton Vance Management, a part of Morgan Stanley Investment Management. It was formerly known as Eaton Vance Insured Municipal Bond Fund and operates within the asset management industry, targeting income-focused investors seeking tax-exempt fixed income exposure, with geographic focus on U.S. municipal issuers across various states.
In recent developments, the Fund announced and completed a cash tender offer in late 2024 and early 2025 to purchase up to 5% of its outstanding common shares (2,846,127 shares) at 98% of net asset value, or $10.7664 per share, following pro-ration of the 15.3 million shares tendered; this initiative, launched November 12, 2024, aimed to address discounts to NAV amid municipal bond market dynamics. The tender offer reduced outstanding common shares to approximately 54.1 million post-completion. Eaton Vance Municipal Bond Fund continues active portfolio management under lead portfolio managers Payson F. Swaffield and Adam A. Weigold, with ongoing emphasis on high credit quality and tax-exempt yield generation.
