About AIAHX

American Century Inflation-Adjusted Bond Fund I Class is a mutual fund designed to provide total return and inflation protection consistent with investment in inflation-indexed securities. It primarily invests in a portfolio of inflation-linked securities, such as Treasury Inflation Protected Securities (TIPS), to help preserve purchasing power against rising prices. The fund employs an active, opportunistic approach to securities selection, considering macroeconomic conditions and conducting in-depth credit research to identify relative-value opportunities while managing risks. To enhance return potential, it diversifies beyond TIPS into corporate bonds, securitized sectors, and other fixed-income instruments, with allocations typically including a majority in U.S. government securities, supplemented by securitized and credit holdings. Portfolio characteristics feature a mix of maturities, with significant exposure to 1-3 year and 5-10 year durations, and an average effective duration around 6.48 years. Managed by a team of experienced professionals, the fund declares distributions quarterly and belongs to the Inflation-Protected Bond category, benchmarked against the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index. Headquartered in Kansas City, Missouri, American Century Investments offers this I Class share primarily through financial advisors.
