NEW YORK (Standard & Poor's) June 11, 2008--Standard & Poor's Ratings Services
today lowered its ratings to 'D' on 80 classes from 71 U.S. residential
mortgage-backed securities (RMBS) transactions backed by closed-end
second-lien mortgage collateral. Specifically, we lowered our ratings on 12
classes from nine deals to 'D' from 'CC' and 66 classes from 60 deals to 'D'
from 'CCC'. In addition, we lowered our rating on class I-B-5 from Terwin
Mortgage Trust 2006-1 to 'D' from 'B'. Finally, we lowered our rating on class
IV-M-6 from American Home Mortgage Investment Trust 2006-3 to 'D' from 'BBB+'
(see list).
The downgrades reflect the deteriorating performance of the collateral
pools as monthly net losses continue to significantly outpace monthly excess
interest cash flows, resulting in the complete write-down of the
overcollateralization (O/C) for these deals. Some of these transactions have
already experienced a complete write-down to the principal balance of other
subordinate classes over the past few months. The affected classes experienced
principal write-downs during the May 2008 remittance period.
As of the May 2008 distribution period, cumulative realized losses ranged
from 3.11% (Terwin Mortgage Trust 2003-7SL) to 31.43% (CWABS Asset Backed
Certificates Trust 2006-SPS1) of the original principal balances, and total
delinquencies ranged from 10.76% (Nomura Asset Acceptance Corp. Alternative
Loan Trust Series 2005-S1) to 41.25% (Structured Asset Securities Corp.
Mortgage Loan Trust 2006-ARS1) of the current principal balances. Seasoning
for these transactions ranged from 11 months (Merrill Lynch Mortgage Investors
Trust Series 2007-SL1) to 52 months (Terwin Mortgage Trust 2003-7SL), and
these transactions have outstanding pool factors ranging from approximately
4.86% (Terwin Mortgage Trust 2003-7SL) to 78.60% (ACE Securities Corp. Home
Equity Loan Trust Series 2007-ASL1). If delinquencies continue to translate
into realized losses, we will likely take further negative rating actions on
the outstanding classes from these transactions.
Subordination, O/C, and excess interest cash flow provide credit support
for these deals. The collateral originally consisted of 30-year, fixed-rate,
closed-end second-lien mortgage loans secured by one- to four-family
residential properties.
