Dear Mr. Greene:

Pursuant to Rule 461(a) under the Securities Act of 1933, as amended (the “Securities Act”), the Fund respectfully requests that the effectiveness of the above-referenced registration statement on Form N-2 (the “Registration Statement”) be accelerated to Thursday, February 27, 2014, or as soon thereafter as practicable.

The Fund acknowledges that (i) should the Securities and Exchange Commission (the “Commission”) or its staff (the “staff”), acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any actions with respect to the filing, (ii) the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Fund from its full responsibility for the adequacy and accuracy of the disclosure in the filing, and (iii) the Fund may not assert this action as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Please call Brent Bates of Ropes & Gray LLP at 212-596-9143 as soon as the Registration Statement has been declared effective.

Very truly yours,
