Shares of closed-end investment companies, including those of the Funds, may frequently trade at prices lower than NAV, the Funds’ Board of Trustees (Board) has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from NAV in respect of Common Shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at NAV, or the conversion of the Fund to an open-end investment company. The Funds cannot assure you that their Board will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount. SENIOR SECURITIES The following table sets forth information regarding each Fund’s outstanding senior securities as of the end of each of the Fund’s last ten fiscal years, as applicable. Each Fund’s senior securities during this time period are comprised of borrowings that constitute “senior securities” as defined in the Investment Company Act of 1940, as amended (1940 Act). The information in this table as of and for the fiscal years ended 2024 through 2015 has been audited by KPMG LLP, independent registered public accounting firm. The Funds’ audited financial statements, including the report of KPMG LLP thereon, and accompanying notes thereto, are included in this Annual Report.
