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 expectation
on the pool of mortgages backing the underlying certificate.
The resecuritization is backed by the class 7-A1 (the "Underlying
Certificate") issued by CSMC Mortgage-Backed Trust Series 2006-9.
The underlying certificate is backed primarily by first-lien,
Alt-A residential mortgage loans.
The resecuritization has three depositable classes (Classes A3,
A4, and A5) that can be deposited in exchange for one or more classes
of exchangeable certificates (Classes A1, A2, and A6 through
A14).The Class A3 issued by Morgan Stanley 2008-1R is a
senior class, supported by a subordinated bond Class A4, which
receives principal payments after Class A3 but absorbs losses before Class
A4. The class A5 is an interest only bond whose notional amount
is linked to the Class A4.
Moody's ratings on the resecuritization certificates are based on:
(i) The updated expected loss on the pool of loans backing the underlying
certificate and the updated rating on the underlying certificate.
Moody's current loss expectation on the Alt-A pool backing the
CSMC 2006-9 underlying certificate and the current rating of this
underlying certificate can be found at http://www.moodys.com/viewresearchdoc.aspx?docid=PBS_SF240070.
(ii) The credit enhancement available to the underlying certificate,
and
(iii) The structure of the resecuritization transaction.
Moody's first updated its loss assumption on the underlying pool of mortgage
loans (backing the underlying certificate) and then arrived at updated
rating on the underlying certificate. The rating on the underlying
certificate is 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 Alt-A pools,
please refer to the methodology publications "Alt-A RMBS Loss Projections
Update: 2010", available on Moodys.com.
In order to determine the ratings of depositable resecuritized bonds,
loss on the underlying certificate was ascribed to the resecuritized classes,
according to the structure of the resecuritized transaction. The
losses on the resecuritized certificates are allocated "bottom up" with
the subordinate class taking losses ahead of the senior class.
Principal payments to the certificates are allocated sequentially,
with the senior class being paid ahead of the subordinate class.
In order to determine the ratings of exchangeable resecuritized bonds,
losses on the depositable certificates were ascribed to these exchangeable
classes, according to the available exchanges of the depositable
classes for exchangeable classes.
The primary source of assumption uncertainty is the current macroeconomic
environment, in which unemployment remains at high levels,
and weakness persists in the housing market. Moody's notes an increasing
potential for a double-dip recession, which could cause a
further 20% decline in home prices (versus its baseline assumption
of roughly 5% further decline). Overall, Moody's assumes
a further 5% decline in home prices with stabilization in early
2011, accompanied by continued stress in national employment levels
through that timeframe.
As part of the sensitivity analysis, we stressed the updated expected
loss on the pool of loans backing the underlying certificates by an additional
10% and found that the implied ratings of the resecuritized bonds
do not change.
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.
