(1) The Registrant is relying on Rule 457(c) under the Securities Act of 1933 to calculate the registration fee. The Maximum Aggregate Offering Price is estimated solely for the purpose of determining the registration fee in accordance with Rule 457(c) under the Securities Act of 1933 based on the average of the high and low sales prices of the shares of Common Shares on June 13, 2023, as reported on the New York Stock Exchange. The proposed maximum offering price per security will be determined, from time to time, by the Registrant in connection with the sale by the Registrant of the securities registered under this Registration Statement.

(2) Amount represents $110.20 previously paid to register $1,000,000 of Common Shares, plus $22,206.40 to register the additional $201,510,000 of Common Shares registered hereby.

(3) The Registrant previously paid $110.20 in connection with the filing of the Registrant’s Registration Statement on Form N-2 (File No. 333-271575) with the Securities and Exchange Commission on May 2, 2023.
