Ten classes from four issues of Structured Asset Securities Corp. mortgage pass-through certificates have been downgraded by Fitch Ratings, and five classes have been placed on Rating Watch Negative.In addition, two classes were upgraded, and the ratings on 31 other classes in five SASCO transactions were affirmed. Fitch attributed the downgrades to a deterioration in the relationship between credit enhancement and loss expectations. The collateral in the pools consists of fixed- and adjustable-rate conventional mortgages, substantially all of which have original terms of 30 years.
