OREANDA-NEWS. Fitch Ratings has affirmed 12 classes of Credit Suisse First Boston Mortgage Securities Corp., series 2010-RR1. A detailed list of ratings actions follows at the end of this press release.

KEY RATING DRIVERS

This transaction is a resecuritization of the ownership interest in three commercial mortgage-backed certificates which total $229,254,278. The transaction consists of three
non-pooled re-REMIC bond groups each backed by one underlying supersenior bond. Each bond group is split into one senior and one subordinate class of certificates. Principal and interest from the underlying certificates is applied to its respective bond group in sequential order, while losses are applied in reverse sequential order.

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 $76,278,485

Fitch affirmed class A-4 at 'Asf' with a Stable Outlook on Feb. 4, 2016. The underlying bond has approximately 30.5% 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 size above reflects 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 $76,278,485.

Banc of America Commercial Mortgage Inc. Series 2007-3

--7.9% interest in class A-4, in the amount of $67,982,793

Class A-4 is rated 'AAAsf' with a Stable Outlook and was last affirmed by Fitch on Sept. 11, 2015. The underlying class A-4 has approximately 29.9% 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 size above reflects 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 $76,278,793.

RATING SENSITIVITIES

The deal structure provides additional credit support for all but the most junior tranches. The ratings on all but the 2-B-A certificate are expected to remain stable given the current credit enhancement of the underlying bonds in addition to the added credit enhancement provided by the junior tranches. The Negative Outlook on the 2-B-A certificate is maintained to reflect the possibility of future downgrades if expected losses on underlying loans in special servicing increase. The 2-B and 2-B-B certificates may be upgraded if the performance of the underlying pool warrants. Conversely, the classes may be downgraded should the underlying pools deteriorate further than current estimates indicate.
