RATING DRIVERS
The affirmations of the re-REMIC transaction are the result of the affirmations of the underlying bonds, both rated by Fitch.

This transaction is a resecuritization of the ownership interest in two commercial mortgage-backed certificates which total \$164.95 million. The transaction consists of two non-pooled re-REMIC bond groups, each backed by one underlying super-senior bond. Each re-REMIC 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.

RATING SENSITIVITY
The Rating Outlook on the bonds remains Stable as no rating actions are expected. 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 2-B and 2-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.
