In accordance with the Fund’s By-Laws, a quorum is constituted by the presence in person or by proxy of the holders of record of a majority of the outstanding shares of the Fund’s common stock (“Common Stock”) entitled to vote at the Meeting. For purposes of determining the presence of a quorum for transacting business at the Meeting, abstentions and broker non-votes, if any, will be treated as shares of Common Stock that are present but which have not been voted. In the event of any conflict between a description of the Fund’s By-Laws in the proxy statement and the Fund’s By-Laws, the Fund’s By-Laws will control.

The Board has fixed the close of business on August 29, 2025 as the record date (the “Record Date”) for the determination of stockholders of the Fund entitled to notice of and to vote at the Meeting or any adjournment or postponement thereof.
