Lehman Alt-A Classes Downgraded

Nine classes from mortgage pass-through certificates issued by Lehman Brothers in 2006 have been downgraded by Fitch Ratings.In addition to the downgrades in LMT 2006-6 group 1 and LMT 2006-9, Fitch also placed one class on Rating Watch Negative and removed one class from Rating Watch Negative. Fitch also affirmed the ratings on 11 LMT classes. The negative rating actions were attributed to a deterioration in the relationship between credit enhancement and expected losses. The collateral for the deals consists of alternative-A mortgage loans.
