New York, May 12, 2011 -- Moody's Investors Service has downgraded the ratings of 61 tranches and
has confirmed the ratings of six tranches issued by 15 RMBS resecuritization
transactions.
RATINGS RATIONALE
The actions are a result of the bonds not having sufficient credit enhancement
to maintain the current ratings when compared to the revised loss expectations
on the pools of mortgages backing the underlying certificates.
The principal methodology used in these ratings is described in the "Surveillance
Approach for Resecuritized transactions" section in "Moody's
Approach to Rating US Resecuritized Residential Mortgage-Backed
Securities" published in February 2011.
The underlying certificates backing each resecuritization and the type
of collateral backing each underlying certificate can be found at http://www.moodys.com/viewresearchdoc.aspx?docid=PBS_SF245176.
Moody's ratings on the resecuritization notes are based on:
(i) The updated expected loss on the pools of loans backing the underlying
certificates and the updated ratings on the underlying certificates.
Moody's current loss expectations on the 2005-2008 vintage Alt-A,
Option Arm, Subprime, and Prime Jumbo pools backing the underlying
certificates and ratings of these underlying certificates can be found
at
http://www.moodys.com/page/viewresearchdoc.aspx?docid=PBS_SF198174,
http://www.moodys.com/viewresearchdoc.aspx?docid=PBS_SF225686,
http://www.moodys.com/viewresearchdoc.aspx?docid=PBS_SF198689,
and http://www.moodys.com/page/viewresearchdoc.aspx?docid=PBS_SF196023
respectively.
(ii) The credit enhancement available to the underlying certificates,
and
(iii) The structure of the resecuritization transaction.
Moody's first updated its loss assumption on the underlying pools of mortgage
loans (backing the underlying certificates) and then arrived at updated
ratings on the underlying certificates. The ratings on the underlying
certificates are based on expected recoveries on the bonds under ninety-six
different combinations of six loss levels, four loss timing curves
and four prepayment curves. The volatility in losses experienced
by a tranche due to small increments in losses on the underlying mortgage
pool is taken into consideration when assigning ratings.
For details regarding Moody's approach to estimating losses on 2005-2008
vintage Alt-A / Option Arm, Subprime, and Prime Jumbo
pools, please refer to the methodology publication " Alt-A
RMBS Loss Projection Update: February 2010", " Subprime
RMBS Loss Projection Update: February 2010", and "Prime
Jumbo RMBS Loss Projection Update: January 2010", available
on Moodys.com.
In order to determine the ratings of the resecuritized bonds, losses
on the underlying certificates were ascribed to the resecuritized bonds,
according to the structure of each resecuritized transaction.
The primary source of assumption uncertainty is the current macroeconomic
environment, in which unemployment levels remain high, and
weakness persists in the housing market. Overall, Moody's
assumes a further 5% decline in home prices with stabilization
in late 2011, accompanied by continued stress in national employment
levels through that timeframe.
Moody's Investors Service received and took into account a third party
due diligence report on the underlying assets or financial instruments
in this transaction and the due diligence reports had neutral impact on
the ratings.

Moody's takes action on $1.98 billion of resecuritized RMBS issued between 2005 and 2008
