DBRS has today assigned the following ratings to the Mortgage Certificate-Backed Certificates, Series 2009-R6 issued by Banc of America Funding 2009-R6 Trust (the Trust).

-- $17.8 million Class 1-A-1 rated at AAA
-- $36.7 million Class 3-A-1 rated at AAA

DBRS rates Groups 1 and 3 in this resecuritization trust. Group 1 is backed by a percentage interest of Banc of America Mortgage 2007-3 Trust Class 1-A-1 Certificates. Group 3 is backed by a percentage interest of three senior residential mortgage-backed securities (RMBS) from WaMu Mortgage Pass-Through Certificates Series 2006-AR10, 2006-AR14 and 2006-AR18, respectively. Within each DBRS-rated group, the AAA ratings on the Class A-1 certificates reflect the credit enhancement provided by subordination. The ratings also reflect the quality of the underlying securities.

DBRS does not rate the Class 1-A-2 certificates, the Class 3-A-2 certificates or any certificates in Groups 2 and 4.

Interest and principal payments on the certificates will generally be made on the 26th day of each month, commencing in July 2009. Within each group, interest payments will be distributed on a pro rata basis to the certificates and principal payments will be distributed on a sequential basis to the certificates until the certificate principal balance has been reduced to zero.

Any losses realized from the underlying securities will be allocated reverse sequentially to the certificates within each group until their principal balances have been reduced to zero.

The Trust is a resecuritization consisting of six senior RMBS represented by various real estate mortgage investment conduits (REMICs). For the DBRS-rated groups, the REMIC trusts are backed by pools of prime first lien, one- to four-family residential mortgages.
