Item 4 is hereby amended and supplemented as follows: On January 24, 2025, Saba Capital filed a preliminary proxy statement (the "Preliminary Proxy Statement") with the Securities and Exchange Commission expressing its opposition to and asking shareholders to oppose the Issuer's plan to reorganize into a new fund advised by Victory Capital Management Inc., as such reorganization does not provide the Issuer's shareholders with the opportunity to exit their investment in the Issuer and receive the net asset value of their shares. The foregoing summary of the Preliminary Proxy Statement is not complete and is qualified in its entirety by reference to the Preliminary Proxy Statement, which is attached hereto by reference as Exhibit 3 to this Schedule 13D/A and incorporated by reference herein.
