Dear Mr. Slivka:

Pursuant to Rule 461 under the Securities Act of 1933, as amended, the Registrants hereby respectfully request that the Securities and Exchange Commission (the “Commission”) take such action as may be necessary and proper in order that the above-referenced Registration Statement be declared effective at 12:00 p.m. Eastern Standard Time on Wednesday, December 21, 2011, or as soon thereafter as practicable.

In connection with this request, the Registrants acknowledge that:

1. Should the Commission or the Staff, acting pursuant to delegated authority, declare the Registration Statement effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement;

2. The action of the Commission or the Staff, acting pursuant to delegated authority, in declaring the Registration Statement effective, does not relieve the Registrants from their full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement; and
