DBRS Rates Deutsche Mortgage Securities, Inc. REMIC Trust, Series 2010-RS1

DBRS has today assigned the following ratings to the REMIC Trust, Series 2010-RS1 Certificates issued by Deutsche Mortgage Securities, Inc. (the Trust).

-- $41.8 million Class A-1 rated at "A"

This resecuritization trust consists of one seasoned senior residential mortgage-backed security (RMBS). The "A" rating on the Class A-1 certificates reflects the credit enhancement provided by Class A-2 via subordination and the quality of the underlying security.

DBRS does not rate the Class A-2 certificates in this transaction.

Interest and principal payments on the certificates will be made generally on the 25th day of each month commencing in April 2010. Interest payments will be distributed on a pro rata basis to the certificates, and principal will be distributed on a sequential basis to the certificates, until the principal balances thereof are reduced to zero.

Any losses realized from the underlying securities will be allocated in a reverse numerical order to the certificates.

The Trust is a resecuritization of one senior RMBS, which is backed by a pool of Alt-A, fixed-rate, first-lien, one- to four-family residential mortgages.
