RATINGS RATIONALE
The actions reflect the recent performance of the underlying pools and
Moody's updated loss expectation on these pools. The rating upgrades
are due to the stable to improved collateral performance of the related
underlying pools and the increase of credit enhancement available to the
bonds. The rating upgrades on Classes II-A-1,
II-A-3, II-A-4, II-A-6a
and II-A-6b from Bear Stearns ALT-A Trust 2004-11,
Classes I-A-5, I-A-6 and II-AR-1
from Deutsche Mortgage Securities, Inc. Mortgage Loan Trust,
Series 2004-3, and Class A from Thornburg Mortgage Securities
Trust 2003-2 are solely due to the increase of credit enhancement
available to the bonds. The rating upgrades on tranches from Structured
Asset Securities Corp Trust 2004-11XS are due to the credit enhancement
available to the bonds and their current cash flow priority in a sequential
pay waterfall. The rating downgrades are due to the deterioration
of credit enhancement available to the bonds.
The principal methodology used in these ratings was "US RMBS Surveillance
Methodology" published in January 2017. Please see the Rating
Methodologies page on www.moodys.com for a copy of this
methodology.
Additionally, the methodology used in rating Bear Stearns Asset-Backed
Securities Trust 2003-AC7 Class A-4 was "Moody's Approach
to Rating Structured Finance Interest-Only Securities" published
in October 2015. Please see the Rating Methodologies page on www.moodys.com
for a copy of this methodology.
Factors that would lead to an upgrade or downgrade of the ratings:
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 4.8% in January 2017 from 4.9%
in January 2016. Moody's forecasts an unemployment central range
of 4.5% to 5.5% for the 2017 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 2017. 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.
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 credit rating action on the support provider and in relation to
each particular credit 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 credit rating action,
and whose ratings may change as a result of this credit 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.
Please see the ratings tab on the issuer/entity page on www.moodys.com
