DBRS Confirms Claris IV Limited Series 25

DBRS has today confirmed the following ratings on the Classes issued by Claris IV Limited Series 25. Claris IV Limited Series 25 is collateralized primarily by a portfolio of U.S. residential mortgage-backed securities (RMBS) and other asset-backed securities (ABS). The DBRS ratings of the Class I-A Swap, Class I-B Swap, and Class I-C Swap address the probability of breaching their respective attachment points as defined in the transaction documents at or prior to their maturity dates.

The actions reflect (a) the deterioration in credit quality of the underlying collateral pool since the transaction was last assigned a DBRS rating on June 30, 2009, (b) amendments to the transaction as of August 17, 2010, and (c) additional subordination to the Claris IV Limited Series 25 Class I-A Swap, Class I-B Swap, and Class I-C Swap as of August 17, 2010.
