On February 23, 2026, TDI was reported as having 2,313 Variable Rate Demand Preferred Shares treated as acquired in a non-cash transaction.

According to the disclosure, these 2,313 shares were received from the fund in connection with the reorganization of BlackRock MuniVest Fund, Inc. and BlackRock MuniVest Fund II, Inc. into this fund, through an exchange of previously held preferred shares of those funds for an equal number of Variable Rate Demand Preferred Shares. After this transaction, TDI beneficially owned 5,877 Variable Rate Demand Preferred Shares of the fund. TDI is wholly owned by The Toronto-Dominion Bank through intermediate holding entities, which therefore hold an indirect interest in these shares while jointly filing this statement and expressly disclaiming group status under Section 13(d).
