Terwin MBS Classes Downgraded

Two classes of Terwin Mortgage Trust mortgage-backed securities have been downgraded by Moody's Investors Service, and five classes have been placed under review for possible downgrade.Class B-6 of Terwin Mortgage Trust series 2006-2HGS was downgraded from B1 to Caa3, and class B-7 was downgraded from Caa3 to C. Classes B-3, B-4, and B-5 of the same transaction were placed under review for possible downgrade, as were classes B-4 and B-5 of Terwin Mortgage Trust series 2006-4SL. The negative rating actions were attributed to losses that have eroded subordination and caused credit enhancement to fall too low to support the existing ratings.
