The Fund will seek to achieve its investment objectives by investing, directly or indirectly, at least 80% of its Managed Assets in municipal bonds, the interest on which is, in the opinion of bond counsel to the issuers, generally excludable from gross income for regular U.S. federal income tax purposes, except that the interest may be includable in taxable income for purposes of the Federal alternative minimum tax. In order to qualify to pay exempt-interest dividends, which are items of interest excludable from gross income for federal income tax purposes, the Fund will seek to invest at least 50% of its Managed Assets directly in such Municipal Bonds.
