About AYMCX

The American Century High-Yield Municipal Fund Class C is a mutual fund that targets investors seeking a high level of income that is exempt from federal income tax. This fund primarily invests in a diversified portfolio of high-yield municipal securities, often referred to as "junk bonds," which are issued by or on behalf of state and local governments and their agencies across the United States. By focusing on lower-rated, higher-yielding muni bonds, the fund aims to deliver attractive tax-advantaged income, while also maintaining capital appreciation as a secondary objective. Notably, at least 80% of its assets are consistently allocated to municipal securities whose interest payments are exempt from federal income tax. The fund's holdings may include some securities that are not exempt from the federal alternative minimum tax. As part of the high yield munis category, this fund plays a significant role for investors interested in maximizing after-tax income, especially those in higher tax brackets. The fund distributes income on a monthly basis and is designed to complement broader taxable and tax-exempt fixed-income allocations within diversified portfolios.
