American Century Intermediate-Term Tax-Free Bond Fund - Y Class 

This fund primarily channels its investments into high-quality fixed-income instruments. Under typical market conditions, a minimum of 80% of its net capital will be allocated to debt obligations that provide interest payments free from federal income taxation. The portfolio is structured to maintain a weighted average maturity between three and ten years, inclusive. However, no specific maturity limits are imposed on individual securities held within the fund. Furthermore, the investment team is authorized to purchase investment-grade bonds whose interest income is exempt from standard federal income tax, even if it remains subject to the federal alternative minimum tax.
