RATINGS RATIONALE
The rating actions are a result of the recent performance of the underlying
pools and reflect Moody's updated loss expectation on the pools.
The ratings upgraded are the result of the amortization and improved credit
enhancement on these bonds. The ratings downgraded are a result
of weaker collateral performance and higher expected losses on the underlying
collateral.
In addition to performance, today's rating action on Class A-X
from MASTR Alternative Loan Trust 2006-2 reflects correction of
a prior error. In accordance with Moody's methodology for rating
Interest-Only (IO) securities, the rating of this interest-only
tranche should be capped at the rating of the highest rated tranche in
the same group. In the February 22, 2012 rating action,
the rating of Class A-X was capped instead to the highest rated
tranche in the deal. The error has now been corrected, and
today's rating action reflects this change.
The principal methodology used in these ratings was "US RMBS Surveillance
Methodology" published in November 2013. Please see the Credit
Policy page on www.moodys.com for a copy of this methodology.
Factors that would lead to an upgrade or downgrade of the rating:
Ratings in the US RMBS sector remain exposed to the high level of macroeconomic
uncertainty, and in particular the unemployment rate. The
unemployment rate fell to 5.5% in February 2015 from 6.7%
in February 2014. Moody's forecasts an unemployment central range
of 5% to 6% for the 2015 year. Deviations from this
central scenario could lead to rating actions in the sector. House
prices are another key driver of US RMBS performance. Moody's expects
house prices to continue to rise in 2015. Lower increases than
Moody's expects or decreases could lead to negative rating actions.
Finally, 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.

REGULATORY DISCLOSURES
For further specification of Moody's key rating assumptions and sensitivity
analysis, see the sections Methodology Assumptions and Sensitivity
to Assumptions of the disclosure form.
Moody's did not receive or take into account a third party assessment
on the due diligence performed regarding the underlying assets or financial
instruments related to the monitoring of these transactions in the past
six months.
The analysis includes an assessment of collateral characteristics and
performance to determine the expected collateral loss or a range of expected
collateral losses or cash flows to the rated instruments. As a
second step, Moody's estimates expected collateral losses or cash
flows using a quantitative tool that takes into account credit enhancement,
loss allocation and other structural features, to derive the expected
loss for each rated instrument.
Moody's quantitative analysis entails an evaluation of scenarios
that stress factors contributing to sensitivity of ratings and take into
account the likelihood of severe collateral losses or impaired cash flows.
Moody's weights the impact on the rated instruments based on its
assumptions of the likelihood of the events in such scenarios occurring.
For ratings issued on a program, series or category/class of debt,
this announcement provides certain regulatory disclosures in relation
to each rating of a subsequently issued bond or note of the same series
or category/class of debt or pursuant to a program for which the ratings
are derived exclusively from existing ratings in accordance with Moody's
rating practices. For ratings issued on a support provider,
this announcement provides certain regulatory disclosures in relation
to the rating action on the support provider and in relation to each particular
rating action for securities that derive their credit ratings from the
support provider's credit rating. For provisional ratings,
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
prior to the assignment of the definitive rating in a manner that would
have affected the rating. For further information please see the
ratings tab on the issuer/entity page for the respective issuer on www.moodys.com.
For any affected securities or rated entities receiving direct credit
support from the primary entity(ies) of this rating action, and
whose ratings may change as a result of this rating action, the
associated regulatory disclosures will be those of the guarantor entity.
Exceptions to this approach exist for the following disclosures,
if applicable to jurisdiction: Ancillary Services, Disclosure
to rated entity, Disclosure from rated entity.
Regulatory disclosures contained in this press release apply to the credit
rating and, if applicable, the related rating outlook or rating
review.
Please see www.moodys.com for any updates on changes to
the lead rating analyst and to the Moody's legal entity that has issued
the rating.
