The Registration Statement submitted herewith relates to the initial public offering of the Company’s common stock. A formal filing of the Registration Statement will be made at a later date, which in no event will be later than 21 days before the Company commences its road show. On behalf of our client, we confirm that as of the date of this letter, the Company is an “emerging growth company” as defined under Section 2(a)(19) of the Securities Act, because its total gross revenues during the year ended December 31, 2011, its last completed fiscal year, were less than $1 billion. In addition, we confirm that as of the date of this letter, none of the disqualifying conditions set forth in Section 2(a)(19) of the Securities Act have occurred. A copy of the Registration Statement has been attached to our e-mail as a text searchable PDF file, labeled DRAFTRS.pdf. We hereby notify the Commission that the Company does not intend to take advantage of the extended transition period for adopting new or revised accounting standards provided for emerging growth companies under Section 7(a)(2)(B) of the Securities Act.
