Ladies and Gentlemen:

The Company acknowledges that it is responsible for the adequacy and accuracy of the disclosure in the Preliminary Proxy Materials for the Perimeter Small Cap Growth Fund (the “Preliminary Proxy”).  The Company further acknowledges that staff comments or changes to disclosure in response to staff comments on the Preliminary Proxy may not foreclose the Securities and Exchange Commission (the “Commission”) from taking any action with respect to the Preliminary Proxy.  The Company further acknowledges that it may not assert staff comments as a defense in any proceeding initiated by the Commission or any party under the federal securities laws of the United States of America.

Very truly yours,
The RBB Fund, Inc.
