About AIANX

American Century Inflation-Adjusted Bond Fund R5 Class is a mutual fund designed to provide total return and inflation protection through investments primarily in inflation-indexed securities. Under normal market conditions, it allocates at least 80% of its net assets to inflation-adjusted bonds, with the remainder potentially in derivatives like futures contracts, inflation swaps, and credit default swaps to manage duration, inflation, and credit exposure. The portfolio predominantly features U.S. government securities, supplemented by smaller positions in corporates, securitized assets, and cash equivalents, emphasizing high credit quality with an average effective duration around 6.55 years and maturity of about 7.99 years. This R5 share class targets institutional investors seeking preservation of purchasing power against inflation within the fixed-income market. Managed by American Century Investments, the fund plays a key role in inflation-protected bond strategies, offering exposure to Treasury Inflation-Protected Securities (TIPS) and related instruments to mitigate real return erosion in rising price environments.
