About ASDOX

American Century Short Duration Fund G Class is an actively managed mutual fund focused on high-quality, short‑maturity fixed income securities. Its primary purpose is to provide current income while seeking to limit price volatility through a portfolio concentrated in investment‑grade, non–money market debt. The strategy invests across notes and bonds, commercial paper, U.S. Treasury securities, and securitized instruments such as mortgage‑ and asset‑backed securities, including collateralized mortgage and loan obligations, with an emphasis on maintaining a short interest‑rate profile. Positioned within the short‑term bond category, the fund’s mandate prioritizes credit quality and duration control relative to benchmarks centered on the 1–3 year segment of the U.S. government and corporate markets. This approach makes it a tool for investors seeking bond exposure geared toward stability of principal and predictable income streams, particularly in environments where interest‑rate sensitivity is a concern. The G Class structure features a management fee waiver by the advisor, reflecting a cost‑conscious share class design overseen by the fund’s Board of Trustees. The fund plays a role in the market by channeling capital to high‑grade issuers while providing liquidity and near‑term financing across government and corporate sectors.
