Moody's Eyes Option One MBS Classes

Eight tranches from five deals originated with collateral from Option One Mortgage Corp. in 2003 have been placed under review for possible downgrade by Moody's Investors Service.The affected classes from Option One Mortgage Loan Trust are as follows: series 2003-3, classes M-5 and M-6; series 2003-4, class M-6; series 2003-5, classes M-5 and M-6; and series 2003-6, class M-6. The affected classes from ABFC 2003-OPT1 Trust were classes M-5 and M-6 of series 2003-OPT1. In addition, Moody's has placed two tranches from one Option One deal under review for possible upgrade. The negative rating actions were attributed to credit enhancement levels that may be low given the projected losses on the underlying pools. The transactions consist primarily of first-lien, adjustable- and fixed-rate subprime mortgage loans.
