Pioneer AMT-Free Municipal Fund Class Y (PBYMX)

This fund typically allocates a minimum of 80% of its total assets (which includes any borrowed capital used for investment) to high-quality municipal debt instruments. These securities must have maturities exceeding one year and provide interest income that is exempt from ordinary federal income taxation. Furthermore, the fund generally avoids investments in bonds whose interest might be classified as a tax preference item for the federal Alternative Minimum Tax (AMT).
