RATINGS RATIONALE
The actions are a result of the recent performance of the underlying pools
and reflect Moody's updated loss expectations on these pools. The
downgrades are a result of deteriorating performance and structural features
resulting in higher expected losses for certain bonds than previously
anticipated. The upgrades are due to improvement in collateral
performance.
The methodologies used in these ratings were "Moody's Approach to Rating
US Residential Mortgage-Backed Securities" published in December
2008 and "Pre-2005 US RMBS Surveillance Methodology" published
in January 2012. The methodology used in rating Interest-Only
Securities was "Moody's Approach to Rating Structured Finance Interest-Only
Securities" published in February 2012. Please see the Credit Policy
page on www.moodys.com for a copy of these methodologies.
Moody's adjusts the methodologies noted above for 1) Moody's current view
on loan modifications and 2) small pool volatility.
Loan Modifications
As a result of an extension of the Home Affordable Modification Program
(HAMP) to 2013 and an increased use of private modifications, Moody's
is extending its previous view that loan modifications will only occur
through the end of 2012. It is now assuming that the loan modifications
will continue at current levels until 2014.
Small Pool Volatility
To project losses on prime jumbo pools with fewer than 100 loans,
Moody's first calculates an annualized delinquency rate based on vintage,
number of loans remaining in the pool and the level of current delinquencies
in the pool. For prime jumbo pools originated before 2005,
Moody's first applies a baseline delinquency rate of 3.0%.
Once the loan count in a pool falls below 76, this rate of delinquency
is increased by 1% for every loan fewer than 76. For example,
for a pool with 75 loans, the adjusted rate of new delinquency would
be 3.03%. In addition, if current delinquency
levels in a small pool is low, future delinquencies are expected
to reflect this trend. To account for that, the rate calculated
above is multiplied by a factor ranging from 0.75 to 2.5
for current delinquencies ranging from less than 2.5% to
greater than 10% respectively. Delinquencies for subsequent
years and ultimate expected losses are projected using the approach described
in the methodology publication.
When assigning the final ratings to bonds, in addition to the approach
described above, Moody's considered the volatility of the projected
losses and timeline of the expected defaults.
The primary source of assumption uncertainty is the uncertainty in our
central macroeconomic forecast and performance volatility due to servicer-related
issues. The unemployment rate fell from 8.2% in March
2012 to 7.6% in March 2013. Moody's forecasts
a further drop to 7.5% by 2014. Moody's expects
house prices to drop another 1% from their 4Q2011 levels before
gradually rising towards the end of 2013. Performance of RMBS continues
to remain highly dependent on servicer procedures. Any change resulting
from servicing transfers or other policy or regulatory change can impact
the performance of these transactions.

this announcement provides certain regulatory disclosures in relation
to the provisional rating assigned, and in relation to a definitive
rating that may be assigned subsequent to the final issuance of the debt,
in each case where the transaction structure and terms have not changed

have affected the rating. For further information please see the
