Fitch Takes Various Actions on CSMC Series 2010-RR1

CHICAGO--()--Fitch Ratings has affirmed 10 classes and placed two classes of Credit Suisse First Boston Mortgage Securities Corp., CSMC series 2010-RR1 on Rating Watch Negative. A detailed list of rating actions follows at the end of this press release.

KEY RATING DRIVERS

The Rating Watch Negative placements are due to Fitch placing the underlying CSMC 2007-C5 class A4 on Rating Watch Negative.

This transaction is a resecuritization of the ownership interest in three commercial mortgage-backed certificates which total $250,994,000. The transaction consists of three non-pooled re-REMIC bond groups each backed by one underlying super-senior A-4 bond. Each newly-issued bond group is split into one senior and one support class of certificates. Principal and interest from the underlying commercial mortgage-backed certificates is applied to its respective bond group sequentially while losses from the underlying commercial mortgage-backed certificates are applied to their respective bond group in reverse sequential order.

Credit enhancement is approximately 60% for classes 2-A-A and 3-A-A; 50% for classes 2-A, 2-A-B, 3-A and 3-A-B; 40% for classes 2-B-A and 3-B-A; and 30% for classes 2-B, 2-B-B, 3-B and 3-B-B. Credit enhancement for each class is provided by the structural support of the underlying transaction and the respective subordinate classes in the resecuritization.

The following commercial mortgage-backed securities are collateral for the re-REMIC securities rated by Fitch:

Credit Suisse Commercial Mortgage Trust series 2007-C5

--8.8% interest in class A-4, in the amount of $86,086,000.

Class A-4, rated 'AAA,' was placed on Rating Watch Negative by Fitch on Nov. 25, 2014. The underlying class A-4 has approximately 29.9% credit enhancement. This transaction serves as collateral for the classes 2-A, 2-A-A, 2-A-B, 2-B, 2-B-A and 2-B-B re-REMIC bonds. The class sizes above reflect the potential maximum certificate balance for each class given the exchangeable nature of the certificates. In aggregate, the total principal balance of this securitization can not exceed $86,086,000.

Banc of America Commercial Mortgage Inc. series 2007-3

--7.9% interest in class A-4, in the amount of $79,915,000.

Class A-4 is rated 'AAA' with a Stable Outlook and was affirmed by Fitch on Sept. 19, 2014. The underlying class A-4 has approximately 34.6% credit enhancement. This transaction serves as collateral for the classes 3-A, 3-A-A, 3-A-B, 3-B, 3-B-A and 3-B-B re-REMIC bonds. The class sizes above reflect the potential maximum certificate balance for each class given the exchangeable nature of the certificates. In aggregate, the total principal balance of this securitization cannot exceed $79,915,000.

Any extraordinary trust fund expenses incurred by the Trustee up to the first $200,000 will be reimbursed to the Trustee by an affiliate of the depositor. In the event extraordinary trust fund expenses exceed $200,000, they will be paid from available interest.
