Eaton Vance Maryland Municipal Income Fund 

This fund primarily invests in municipal bonds, dedicating at least 80% of its total assets (including any funds borrowed for investment purposes) to these instruments. These securities are designed to be exempt from regular federal income tax and the specific state taxes detailed in the fund's investment objectives. Typically, at least 75% of its net assets are allocated to municipal obligations considered investment-grade. This quality assessment is made either by their official rating at the time of acquisition or, if unrated, by the investment adviser's determination of equivalent investment-grade quality. The fund operates as a non-diversified portfolio.
