Class A-X-1, Class A-X-2, Class A-X-3, Class A-X-4, Class A-X-5, Class A-X-
6 and Class A-X-7 are interest-only certificates. The class balances represent notional amounts.

Class A-5, Class A-6, Class A-7, Class A-8, Class A-9, Class A-10, Class A-11, Class A-X-5, Class A-X-6 and Class A-X-7 are exchangeable certificates. These classes can be exchanged for combinations of initial exchangeable certificates as specified in the offering documents.

Class A-2, Class A-3, Class A-7, Class A-8, Class A-9 and Class A-10 are super senior certificates. These classes benefit from additional protection from senior support certificates (Class A-4 and Class A-11) with respect to loss allocation.

The AAA (sf) ratings in this transaction reflect the 7.65% of credit enhancement provided by subordination. The AA (sf), A (sf), BBB (sf) and BB (sf) ratings reflect 6.20%, 4.50%, 3.45% and 1.50% of credit enhancement, respectively. Other than the specified classes above, DBRS does not publicly rate any other classes in this transaction.

The Certificates are backed by 525 prime residential mortgage loans with a total principal balance of $381,595,526 as of the Cut-Off Date (January 1, 2015). The mortgage loans were acquired by DLJ Mortgage Capital, Inc. (DLJMC).

The originators for the mortgage pool are New Penn Financial, LLC (New Penn, 20.2%), Quicken Loans Inc. (19.3%), Caliber Home Loans, Inc. (7.6%) and various other originators, each comprising less than 5.0%.

The loans will be serviced by Select Portfolio Servicing, Inc. (68.8%), New Penn doing business as Shellpoint Mortgage Servicing (20.2%), Fifth Third Mortgage Company (4.8%), PHH Mortgage Corporation (3.7%), First Republic Bank (1.5%) and EverBank (0.9%). Wells Fargo Bank, N.A. will act as the Master Servicer and Securities Administrator. Christiana Trust, a division of Wilmington Savings Fund Society, FSB, will serve as trustee. The transaction employs a senior subordinate shifting-interest cash flow structure that is enhanced from a pre-crisis structure.

Each originator has made certain representations and warranties concerning the mortgage loans. The enforcement mechanism for breaches of representations includes automatic breach reviews by a third-party reviewer for any seriously delinquent loans, and resolution of disputes may be ultimately subject to determination in an arbitration proceeding. Certain loans also benefit from representations and warranties backstopped by the seller, DLJMC, a wholly owned subsidiary of Credit Suisse (USA), Inc., in the event of an originator’s bankruptcy or insolvency proceeding, and if the originator fails to cure, repurchase or substitute such breach or loans. Such backstop is, however, subject to certain sunset provisions that give consideration to prior loan performance.

DBRS views the representations and warranties features for this transaction to be consistent with recent DBRS-rated CSMC prime jumbo transactions. However, the relatively weak financial strength of certain originators, coupled with the sunset provisions on the backstop by DLJMC, still demand additional penalties and credit enhancement protections. The full description of the representations and warranties standard, the mitigating factors and the DBRS analysis are detailed in the related presale report.
