The Fund’s investment objective is to provide stockholders with current income exempt from federal income taxes. The Fund’s investment policies provide that it seeks to achieve its investment objective by investing, as a fundamental policy at least 80% of an aggregate of the Fund’s net assets (including proceeds from the issuance of any preferred stock) and the proceeds of any borrowings for investment purposes, in a portfolio of municipal obligations issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies or instrumentalities.
