The fund invests at least 65% of its total assets in Maryland municipal securities, and at least 80% of the fund’s income is expected to be exempt from federal and Maryland state and local income taxes. The fund is a retail money market fund managed in compliance with Rule 2a-7 under the Investment Company Act of 1940.

The securities purchased by the fund are subject to the maturity, credit quality, diversification, liquidity, and other requirements of Rule 2a-7. All securities purchased by the fund present minimal credit risk in the opinion of T. Rowe Price. The fund is managed to provide a stable share price of $1.00 by investing in high-quality U.S. dollar-denominated municipal money market securities. Money market securities are generally high-quality, short-term obligations issued by companies or governmental entities. The fund’s weighted average maturity will not exceed 60 calendar days, the fund’s weighted average life will not exceed 120 calendar days, and the fund will not purchase any security with a remaining maturity longer than 397 calendar days (unless otherwise permitted by Rule 2a-7, such as certain variable and floating rate instruments).

In selecting securities for the fund, the portfolio manager may examine relationships among yields of various types and maturities of money market securities in the context of interest rate outlooks. The fund’s yield will fluctuate with changes in short-term interest rates.

In addition to investing in state and local general obligation bonds, the fund may invest a significant portion of its assets in sectors with special risks, such as health care, transportation, and utilities, as well as private activity bonds (including industrial revenue bonds), which are municipal bonds issued by a government agency on behalf of a private sector company and, in most cases, are not backed by the credit of the issuing municipality. It is possible that 25% or more of the fund’s assets could be invested in municipal securities that would tend to respond similarly to particular economic or political developments. For example, the fund may invest in securities of issuers whose revenues are generated from similar types of projects or operate in similar industries. The fund may at times invest more than 25% of its net assets overall in industrial revenue bonds, but investments in industrial revenue bonds related to the same industry may not exceed 25% of the fund’s net assets. Bonds that are refunded with escrowed U.S. government securities are not subject to the 25% limitation. Refunded bonds may have originally been issued as general obligation or revenue bonds, but become “refunded” when they are secured by an escrow fund, usually consisting entirely of direct U.S. government obligations, U.S. government agency obligations, and/or cash.

Due to seasonal variations in the supply of suitable Maryland municipal securities, the fund may invest in other municipal securities whose interest is exempt from federal but not Maryland income taxes. While efforts will be made to minimize such investments, they could comprise up to 10% of the fund’s annual income.
