DBRS Upgrades Class A-4B of Banc of America Re-REMIC Trust 2009-UBER1

DBRS, Inc. (DBRS) has today upgraded the rating of the following Commercial Mortgage Pass-Through Certificates issued by Banc of America Re-REMIC Trust 2009-UBER1:

-- Class A-4B to AAA (sf) from A (sf)

The trend is Stable.

The transaction is 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 four remaining underlying transactions and classes within the resecuritization are as follows:

-- CWCI 2007-C3, Class A-4
-- LBUBS 2007-C6, Class A-4
-- MLCFC 2007-9, Class A-4
-- MLMT 2007-C1, Class A-4

The rating upgrade reflects the improved credit characteristics of the underlying commercial mortgage-backed securities (CMBS) bonds as a result of scheduled loan amortization, successful loan repayment, proceeds recovered from specially serviced loans and stabilizing cash flows on performing loans. The transaction is a senior/subordinate pass through, providing a sequential-pay structure intended to contain any potential losses within Class A-4B. However, if significant losses were to occur in one of the underlying transactions and its corresponding certificate, the losses would not be offset by the other mortgage pools or certificates within this trust. As such, DBRS rates Class A-4B to a first-dollar loss scenario, and in so doing, DBRS analyzed each of the four underlying transactions separately to determine the ratings floor. Although DBRS does not publicly rate any of the underlying transactions, a detailed level of analysis on each transaction was performed to derive an indicative rating for each contributed certificate.

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 with the actual credit enhancement provided to the contributed certificates within the underlying CMBS structures. Based on that comparison, the rating upgrade was appropriate.

The rating is dependent on the continued performance of the underlying deals.

The rating does not address the likelihood of additional trust fund expenses.
