All trends are Stable.

The transaction is a resecuritization collateralized by the beneficial interests in four super-senior commercial mortgage-backed pass-through certificates from four underlying transactions that were securitized between 2006 and 2007. The collateral is non-pooled and each of the certificates of the underlying transactions consists of a senior/subordinate pass-through providing a sequential-pay structure intended to contain any deal-specific potential losses within each respective B Class. The A and B Exchangeable REMIC Classes of each underlying transaction each have several combinations of Exchangeable Certificates that are also rated by DBRS.

The four underlying transactions and Classes within the resecuritization are as follows:
-- Class A-4 of COBALT CMBS Commercial Mortgage Trust 2006-C1 Commercial
Mortgage Pass-Through Certificates, Series 2006-C1
-- Class A-3 of J.P. Morgan Chase Commercial Mortgage Securities Trust 2006-LDP9 Commercial Mortgage Pass-Through Certificates, Series 2006-LDP9
-- Class A-4 of Wachovia Bank Commercial Mortgage Trust Commercial Mortgage Pass-Through Certificates, Series 2007-C33
-- Class A-4 of Bear Stearns Commercial Mortgage Securities Trust 2007-PWR15, Series 2007- PWR15 Commercial Mortgage Pass-Through Certificates

Although DBRS does not publicly rate any of the underlying transactions, a detailed level of analysis on each transaction was performed by using the CRE Finance Council Investor Reporting Package (CREFC IRP) files from the latest remittance period.

DBRS analyzed the underlying certificates based on the performance of the underlying loans and the transaction structure. DBRS modeled the transactions independently and, in its review, focused on the larger assets, the specially serviced loans and the loans on the servicer’s watchlist, in an effort to most appropriately model the pivotal loans within the transactions that carry a higher likelihood of default. To simulate realized losses expected on all delinquent loans, including 30-day delinquencies, DBRS either modeled these loans with 100% probability of default and the corresponding loss severity, reflective of debt yield derived by using the most recent loan-level cash flow, or ran a liquidation scenario using a haircut to the latest appraisal to account for additional expenses and/or potential future value decline.

The resulting weighted-average credit enhancement requirements for all the loans in the underlying pools, at each respective rating category, were then compared to the actual credit enhancement provided to the contributed certificates within the underlying CMBS structures. Based on that comparison, the ratings confirmations were appropriate.

The ratings are dependent on the continued performance of the underlying deals.

The ratings do not address the likelihood of additional trust fund expenses.
