CHICAGO--(BUSINESS WIRE)--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.

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.
