Eaton Vance Income Fund of Boston Class I

Eaton Vance Income Fund of Boston Class I is an actively managed open‑end mutual fund focused on the U.S. high‑yield bond market. Its primary objective is to deliver a high level of current income, with secondary goals of income growth and capital appreciation through diversified exposure to below‑investment‑grade corporate debt. The strategy is built on fundamental, bottom‑up credit research and a disciplined process emphasizing risk management and relative‑value positioning to pursue competitive risk‑adjusted returns. The portfolio spans hundreds of bonds across many issuers and industries, aiming to balance issuer‑specific opportunities with prudent diversification; recent characteristics show a multi‑year effective duration and intermediate average maturity consistent with high‑yield credit profiles. The fund targets a segment of the fixed‑income market that historically offers higher income potential and lower rate sensitivity than higher‑quality corporates, reflecting its focus on credit risk premia. As an institutional share class, it is designed for investors seeking professionally managed access to leveraged credit with transparent objectives, research depth, and a long‑tenured investment framework.
