About ACSPX
American Century Short Duration Fund R Class is an actively managed mutual fund focused on investment‑grade, short‑maturity fixed income. Its primary objective is to maximize total return, with a secondary goal of delivering a high level of income, while seeking to limit volatility through a short duration profile typically aligned with one to three years. The portfolio invests predominantly in investment‑grade debt, including corporate notes and bonds, U.S. Treasury and agency securities, commercial paper, and securitized assets such as mortgage‑ and asset‑backed securities; it may allocate a minority sleeve to high‑yield debt to enhance income. The fund distributes income monthly and maintains a diversified roster of holdings across sectors and issuers to manage credit and interest‑rate risk. Positioned within the short‑term bond category, it serves as a core short‑duration allocation for investors seeking capital preservation characteristics with current income and lower interest‑rate sensitivity than intermediate‑ or long‑duration strategies. The R share class reflects a retirement‑plan oriented fee structure within the American Century Investments lineup.
