Although the fund may purchase securities of any maturity, the fund invests primarily in longer-term municipal securities. The fund generally seeks higher-yielding municipal bonds, including those that are rated below investment grade (BB and lower, or an equivalent rating) by a major credit rating agency or by T. Rowe Price, known as “junk” bonds.

T. Rowe Price’s active investment management approach emphasizes the value of in-depth fundamental credit research, diversification, and risk management practices. By using fundamental research, T. Rowe Price seeks to select investments for the fund’s portfolio based on its outlook for the different sectors of the tax-free municipal market (for example, T. Rowe Price may emphasize revenue bonds instead of state and local general obligation debt) and specific issuers or securities. The goal of this approach is to seek higher yields while taking a risk-conscious approach. Risk management practices include managing the fund’s duration (which is a measurement of the price sensitivity of a bond or bond fund to changes in interest rates), while also focusing on striking a balance between (i) investing more heavily in certain sectors or issuers and (ii) diversifying the fund’s investments across the broader municipal market.

Normally, at least 80% of the fund’s income will be exempt from federal income taxes. However, up to 20% of the fund’s income could be derived from securities subject to the alternative minimum tax.

From time to time, the fund may invest a significant portion of its assets in sectors with special risks, such as health care, transportation, utilities, or private activity bonds.
