About ACSUX
American Century Short Duration Fund R5 is an actively managed short-term bond mutual fund designed to deliver total return with a secondary emphasis on income. The strategy primarily invests in investment‑grade, non‑money‑market debt across U.S. Treasuries, agencies, and corporate credits, focusing on securities with shorter maturities to help moderate interest‑rate sensitivity. The fund maintains broad diversification across hundreds of holdings, reflecting a multi‑sector approach typical of short‑duration mandates. Within the American Century Short Duration lineup, the R5 share class aligns with retirement and institutional platforms while sharing the same underlying portfolio as other classes such as R6 and Investor. Its profile suits cash‑flow‑oriented allocators seeking bond exposure with lower duration than core intermediate strategies, aiming to balance stability and income generation through monthly distributions. The fund’s market role is to serve as a conservative fixed‑income building block, offering liquidity, diversification, and a potential buffer against equity volatility while participating in front‑end credit and government markets tied to the Bloomberg U.S. 1–3 Year Government/Credit segment.
