DBRS Rates BCAP LLC 2010-RR4 Trust Resecuritization Trust Securities

DBRS has today assigned the following ratings to the Resecuritization Trust Securities issued by BCAP LLC 2010-RR4-I Trust (the Trust).

-- $6.4 million Class IV-A1 rated at "A"

There are two groups in this resecuritization trust. DBRS rates securities from Group IV, which consists of one seasoned senior residential mortgage-backed security (RMBS). The ratings on the securities reflect the credit enhancement provided by subordination within their group and the quality of the underlying asset.

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

Interest and principal payments on the securities will generally be made on the business day following the underlying distribution date (25th of the month), commencing in April 2010. Interest payments on the rated securities will be distributed on a pro rata basis. Principal payments will be distributed on a sequential basis to the rated securities until the principal balances have been reduced to zero.

Any losses realized from the underlying security will be allocated in a reverse sequential order, until the principal balances have been reduced to zero.

Group IV is a resecuritization of one senior RMBS, represented by one real estate mortgage investment conduits (REMICs). Within the DBRS-rated group, the REMIC trust is backed by a pool of seasoned Alt-A, adjustable-rate, first-lien one- to four-family residential mortgages.
