About ASHHX

American Century Short Duration Fund I Class is an actively managed mutual fund focused on high‑quality, short‑maturity fixed income. Its primary objective is to deliver current income while seeking to limit price volatility, particularly during periods of rising interest rates. The portfolio concentrates on investment‑grade debt and maintains a short duration profile, using securities such as notes and bonds alongside commercial paper, mortgage‑ and asset‑backed securities, collateralized loan obligations, collateralized mortgage obligations, and U.S. Treasury securities. The fund’s approach emphasizes investment‑grade credit exposure, with a policy to invest at least a majority of assets in non‑money market, investment‑grade instruments to balance income generation with capital stability. By targeting the one‑to‑three‑year area of the bond market—often referenced against the Bloomberg U.S. 1–3 Year Government/Credit Bond Index—the strategy aims to reduce interest‑rate sensitivity relative to intermediate‑ and long‑duration bond funds. Within the broader market, it serves as a core short‑term bond holding for investors seeking liquidity management and diversification from equity risk, while maintaining a disciplined emphasis on credit quality and controlled duration.
