About AYMIX
American Century High-Yield Municipal Fund I Class is an open-end mutual fund focused on providing shareholders with high current income that is exempt from federal income taxes. The fund primarily invests in municipal and other debt securities, emphasizing high-yield (below investment grade) issues to achieve its income objective, with capital appreciation as a secondary goal. Its portfolio spans a broad spectrum of U.S. municipalities and typically holds hundreds of individual securities, offering diversification across regions and sectors such as local government projects, education, and public utilities. As an institutional share class, it is tailored to large investors, with a high minimum investment requirement and a competitive net expense ratio. The fund is managed by American Century, leveraging collaborative research and credit analysis while navigating credit and liquidity risks inherent in lower-rated municipal bonds. Its monthly income distributions and tax-advantaged status make it a notable asset for investors seeking regular income that is less impacted by federal taxes, playing a key role within the high-yield municipal bond segment of fixed-income markets.
