Following review of the judgment of the District Court, on February 22, 2022, the Funds’ Board of Trustees (the “Board”) amended the Fund’s by-lawsto provide that the Funds’ Control Share By-Lawshall be of no force and effect for so long as the judgment of the District Court is effective and that if the judgment of the District Court is reversed, overturned, vacated, stayed, or otherwise nullified, the Fund’s Control Share By-Lawwill be automatically reinstated and apply to any beneficial owner of common shares acquired in a Control Share Acquisition, regardless of whether such Control Share Acquisition occurs before or after such reinstatement, for the duration of the stay or upon issuance of the mandate reversing, overturning, vacating or otherwise nullifying the judgment of the District Court. On February 25, 2022, the Board and the Funds appealed the District Court’s decision to the U.S. Court of Appeals for the Second Circuit. On November 30, 2023, the U.S. Court of Appeals for the Second Circuit upheld the opinion of the District Court. On February 28, 2024, the Board of the Funds Amended and Restated By-Lawsto eliminate the “control share” provisions.
