About ASDDX
American Century Short Duration Fund R6 is an actively managed short-term bond mutual fund designed to maximize total return with a secondary goal of delivering a high level of current income. The strategy emphasizes **investment‑grade** debt and holds a diversified mix of U.S. Treasuries, agencies, corporate bonds, commercial paper, and other high-quality fixed-income instruments, with a focus on **short effective duration** to help limit price volatility as interest rates change. The fund is positioned within the **Short‑Term Bond** category and targets securities generally in the one‑ to three‑year maturity range, aligning its risk profile with conservative income objectives. It distributes income **monthly** and is managed within the American Century lineup’s institutional R6 share class, which features a comparatively **low net expense ratio** for cost efficiency. The portfolio’s mandate to keep at least a majority in investment‑grade, non–money market debt supports capital preservation while seeking incremental yield over cash. In employer-sponsored retirement plans, it can serve as a **core short-duration fixed-income holding** for liquidity needs, ballast against equity volatility, and diversification of interest-rate and credit exposures.

ASDDX had a total return of 1.98% in the past year, including dividends. Since the fund's inception, the average annual return has been 2.08%.
