MUNI is an actively managed municipal bond fund, meaning that its portfolio tilts are dynamic and can deviate quite a bit from neutral exposure. The fund principally invests in investment-grade municipal bonds that are exempt from federal alternative minimum tax. The fund focuses on bonds with potentially attractive current income by looking for consistent current yields or competitive prices. As an actively managed fund, duration, yield, and geographic biases are all liable to change quite a bit. The fund may, at its own discretion, use other investment techniques such as entering into purchase and sale contracts.
