Eaton Vance Senior Income Trust

Eaton Vance Senior Income Trust is a closed-end fixed income mutual fund headquartered in Boston, Massachusetts, and listed on the New York Stock Exchange. Established in October 1998, the fund is launched and managed by Eaton Vance Management. The trust operates in the asset management sector, specifically within fixed income portfolio management for institutional and individual investors.

The fund's primary investment focus is senior secured floating rate loans in the United States fixed income markets. It constructs its portfolio across diversified sectors while maintaining a specific mandate toward senior secured debt instruments. The trust benchmarks its portfolio performance against the S&P/LSTA Leveraged Loan Index, which tracks the broader leveraged loan market. As a closed-end fund structure, EVF issues a fixed number of shares traded on the public market, distinguishing it from open-end mutual funds that allow continuous share issuance and redemption.

Eaton Vance Management, the fund's investment adviser, provides the operational and portfolio management infrastructure supporting the trust's operations. The fund generates returns for shareholders through interest income and distributions derived from its senior loan holdings.
