The AAA ratings on the Class G30 through Class G85 Notes and the “A” rating on Class G90 (collectively, the Notes) reflect the credit enhancement provided by subordination. The ratings also reflect the quality of the underlying asset, which consists of the CSMC Resecuritization Trust 2006-1R Class 1-A-1 Certificate. The Class G30 through Class G90 Notes (Exchangeable Notes) are exchangeable for certain other classes of Exchanged Notes and vice versa, in the combinations described in Schedule A of the offering memorandum.

Except for the ones noted above, DBRS does not rate any other notes in this trust.

Interest and principal payments on the Notes will generally be made on the third business day following the underlying distribution date (25th day of each month) commencing in January 2010. Interest payments will be distributed on a pro rata basis to the Notes. Principal will be distributed on a sequential basis to the Notes, in numerical order, until the principal balances thereof are reduced to zero.

Losses will be allocated reverse sequentially to the Class G100, G95 and G90 Notes until the Note Principal Amount has been reduced to zero. No losses will be allocated to Class G30 through G85 Notes.
