RATINGS RATIONALE
The actions are a result of the rapidly deteriorating performance of option
arm pools in conjunction with macroeconomic conditions that remain under
duress. The actions reflect Moody's updated loss expectations on
option arm pools issued from 2005 to 2007.
The principal methodology used in these ratings was "Option ARM RMBS Loss
Projection Update: April 2010" published in April 2010.
To assess the rating implications of the updated loss levels on option
arm RMBS, each individual pool was run through a variety of scenarios
in the Structured Finance Workstation® (SFW), the cash flow
model developed by Moody's Wall Street Analytics. This individual
pool level analysis incorporates performance variances across the different
pools and the structural features of the transaction including priorities
of payment distribution among the different tranches, average life
of the tranches, current balances of the tranches and future cash
flows under expected and stressed scenarios. The scenarios include
ninety-six different combinations comprising 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.
Certain securities, as noted above, are insured by financial
guarantors. The Cl. A-1, Cl. A-1I
and Cl. A-NA tranches, contained in this rating action,
are wrapped by Ambac Assurance Corporation (Segregated Account --
Unrated). For securities insured by a financial guarantor,
the rating on the securities is the higher of (i) the guarantor's financial
strength rating and (ii) the current underlying rating (i.e.,
absent consideration of the guaranty) on the security. The principal
methodology used in determining the underlying rating is the same methodology
for rating securities that do not have a financial guaranty and is as
described earlier. RMBS securities wrapped by Ambac Assurance Corporation
are rated at their underlying rating without consideration of Ambac's
guaranty.
In addition, Moody's publishes a weekly summary of structured finance
credit, ratings and methodologies, available to all registered
users of our website, at www.moodys.com/SFQuickCheck.
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.
