About AIAYX

American Century Inflation-Adjusted Bond Fund Y is an open-end mutual fund designed to offer total return and inflation protection by investing primarily in inflation-indexed securities. Its core strategy centers on holding U.S. Treasury Inflation-Protected Securities (TIPS), whose principal and interest payments are adjusted in line with changes in the Consumer Price Index, helping to preserve purchasing power during periods of rising inflation. The fund may also utilize U.S. Treasury futures, inflation swap agreements, and credit default swaps to optimize duration, manage inflation dynamics, and control credit exposure. Targeted at institutional investors, the fund maintains a high-quality bond portfolio with a moderate interest rate sensitivity. It holds a significant concentration in U.S. government securities, including various Treasury notes and securitized issues, and aims to deliver consistent yield while minimizing costs, as reflected in its competitive expense ratio. As part of the inflation-protected bond category, this fund serves a crucial role in diversified portfolios for investors seeking long-term, inflation-sensitive fixed income allocations.
