MainStay MacKay DefinedTerm Municipal Opportunities Fund

MainStay MacKay DefinedTerm Municipal Opportunities Fund is a diversified closed-end management investment company. The Fund's primary investment objective is to seek current income exempt from regular United States (U.S.) federal income taxes (but which may be includable in taxable income for the purpose of the Federal alternative minimum tax). The Fund's secondary objective is a total return. The Fund seeks to achieve its investment objectives by investing, under normal market conditions, 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). The Fund may invest in both tender option bond (TOB) floaters and TOB residuals. The Fund's manager is New York Life Investment Management LLC.
