Four classes from two Credit Suisse First Boston Home Equity Asset Trust securitizations have been downgraded by Fitch Ratings, and six others have been placed on Rating Watch Negative.The downgrades were as follows: series 2005-7, class B-4, from BB-plus to B-plus, and class B-5, from BB to B-plus; and series 2005-8, class B-4, from BB-plus to BB, and class B-5, from BB to B-plus. The securities placed on Rating Watch Negative were as follows: class B-4 of series 2005-6; classes B-2 and B-3 of series 2005-7; classes B-2 and B-3 of series 2005-8; and class B-3 of series 2005-9.
