**Exchangeable REMIC certificates
Fitch does not rate classes 1-A-4, 1-B, and 1-B-B.
The affirmations are the result of the affirmations of the underlying bonds in two transactions rated by Fitch. This transaction is a resecuritization of the ownership interest in two commercial mortgage-backed certificates. The transaction consists of two non-pooled re-REMIC bond groups each backed by one underlying super-senior 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.
The underlying bonds have Stable Outlooks and no rating actions are anticipated.
Credit enhancement is approximately 60% for classes 1-A-A and 2-A-A; 50% for classes 1-A, 1-A-B, 2-A and 2-A-B; 40% for classes 1-B-A and 2-B-A; and 30% for classes 1-A-4, 1-B, 1-B-B, 2-B, 2-B-B, and 2-A-3. Credit enhancement for each class is provided by the structural support of the underlying transaction and the respective subordinate classes in the resecuritization.
