Deutsche MBS Classes Downgraded

Two classes from Deutsche ALT-A Securities Mortgage Loan Trust 2006-AR1 have been downgraded by Fitch Ratings and removed from Rating Watch Negative.Class B-3 was downgraded from BB to B, and class B-4 was downgraded from B to C/DR4. Fitch also placed class B-2 on Rating Watch Negative and affirmed the ratings on three other classes in the deal. The downgrades resulted from a deterioration in the relationship between credit enhancement and expected losses, the rating agency said. The collateral consists of first-lien, adjustable-rate residential mortgage loans.
