First Eagle Senior Loan Fund (FSLF) is a closed-end management investment company that seeks a high level of current income by investing primarily in senior loans made to companies whose debt is rated below investment grade or unrated. The fund offers exposure to floating-rate senior secured loans, high-yield bonds, and other income-producing securities; it employs leverage through borrowings to enhance returns; and provides weekly repurchase offers for liquidity at net asset value. FSLF operates in the fixed income segment of the asset management industry, targeting institutional and retail investors seeking yield in non-investment grade credit markets, with geographic focus on U.S. and global issuers. The fund, managed by First Eagle Alternative Credit, L.P., commenced operations in 2021 and is headquartered in New York. In recent developments, FSLF announced a proposed merger with First Eagle Energy Fund in late 2024 to broaden its credit opportunities amid rising interest rates; it also expanded its portfolio with new senior loan issuances from leveraged buyouts in the energy and technology sectors during 2025.
