About AIANX
The American Century Inflation-Adjusted Bond Fund R5 Class is a mutual fund focused on delivering **total return and inflation protection** by investing primarily in **inflation-indexed debt securities**. This fund allocates at least 80% of its assets to securities such as U.S. Treasury Inflation-Protected Securities (TIPS), and can also include corporate and securitized bonds, all designed to adjust their principal in line with inflation rates. Its primary purpose is to help investors preserve purchasing power during periods of rising prices, making it particularly relevant for long-term capital preservation in retirement or institutional portfolios. Distinguished by a **competitive expense ratio** for its share class and managed by a team with extensive fixed income experience, the fund employs robust risk management strategies to maximize real returns per unit of risk. The fund is predominantly offered through employer-sponsored retirement plans, underscoring its role as a core component of fixed income allocations seeking mitigation against inflation erosion. It tracks performance against the Bloomberg U.S. Treasury Inflation-Protected Securities Index and serves as a key tool for investors aiming to diversify traditional bond exposure while hedging inflation risk.
