DBRS Rates CSMC Series 2012-2R

DBRS, Inc. has assigned the following ratings to the CSMC Series 2012-2R Securities issued by CSMC Series 2012-2R (the Trust).

-- $16.7 million Class 1-A-1* rated at AAA (sf)

-- $17.3 million Class 1-A-8** rated at A (sf)

There are two groups total in this resecuritization trust. DBRS rates notes from Group 1. Group 1 consists of one seasoned senior residential mortgage-backed security (RMBS). The ratings on the offered notes reflect the credit enhancement provided by subordination and the quality of the underlying asset. The Combination Notes are exchangeable for the Exchangeable Notes and vice versa, in the related combinations described in the private placement memorandum.

Other than the classes specified above, DBRS does not rate any other securities in this transaction.

Interest and principal payments on the securities will generally be made on the second business day following the latest underlying distribution date of any security group (the 25th of each month), commencing in March 2012. Within Group 1, interest payments will be distributed on a pro rata basis to the securities. Within Group 1, principal will be distributed on a sequential basis to the securities, in the order of priority specified in the private placement memorandum, until the principal balances thereof are reduced to zero.

Within Group 1, any losses realized from the underlying security will be allocated in a reverse sequential order to the securities.

Group 1 is a resecuritization of one seasoned senior RMBS, represented by one real estate mortgage investment conduit (REMIC). The REMIC is backed by a pool of seasoned Prime, adjustable-rate, first-lien, one- to four-family residential mortgages.

The ratings assigned to the offered securities address (i) the likelihood of the receipt by security holders of all principal distributions to which such security holders are entitled and (ii) the likelihood of the receipt by security holders of the amount of interest actually received by the trust to the extent payable to each class in accordance with the priorities described in the operative documents (as such interest received by the trust may have been reduced as a result of any interest shortfalls allocated to the related underlying securities or any other cause, and as such interest entitlement may be further reduced by the allocation of extraordinary expenses). For more details on the ratings, please refer to the offering and transaction legal documents.

DBRS ReREMIC Methodology Excerpt:
Since a ReREMIC is a pass-through of interest, principal and losses from the underlying certificates, its interest entitlement is usually capped at the actual interest amount collected on the underlying securities.

In other words, a ReREMIC trust cannot pay out more interest than it receives from its collateral, and sometimes, what is collected on the underlying securities can be as low as zero.

When rating ReREMICs, DBRS is assessing the ability of the trust making the full principal payment by the legal final maturity date of the transaction. These transactions typically define interest rate as the lesser of the bond coupon and the available interest funds. Hence, the DBRS rating does not provide an opinion on the timeliness or amount of interest payments the investor may receive. The trust’s only obligation is to pass through the interest proceeds net of fees from the underlying securities.
