New York, February 07, 2018 -- Moody's Investors Service (Moody's) has confirmed the ratings of 47 Interest-Only
(IO) bonds, upgraded the ratings of 2 IO bonds and downgraded the
ratings of 3 IO bonds from 42 US residential mortgage backed securitization
(RMBS) transactions, issued by multiple issuers prior to 2009.
Of these, 3 bonds were among those placed on review on 15 August
2017 in connection with a correction of errors in our earlier analysis,
and 49 bonds were among those placed on review on 29 August 2017 in connection
with a reassessment of our internal linkage of these IO bonds to their
reference bond(s) or pool(s). 6 bonds in this action are IO PO
bonds, which have both an IO component and a principal-only
(PO) component.

RATINGS RATIONALE
Today's action resolves the review of 3 IO bonds which were among those
placed on review in connection with data input errors in prior analyses
and 49 IO bonds which were among those placed on review for a reassessment
of the IO bond linkages captured in our internal database, prompted
by the identification of errors in that database. The factors that
Moody's considers in rating an IO bond depend on the type of referenced
securities or assets to which the IO bond is linked. For IO PO
bonds, which have both an IO component and a PO component,
Moody's determines the rating of IO PO bonds using a weighted average
of the ratings of the two components.
For the 3 IO bonds that had data input errors in prior analysis,
the data inputs were corrected as part of the analysis for this rating
action.
We have reassessed the linkage for the 52 IO bonds in today's rating action,
and determined that 34 of these IO bonds were linked to the appropriate
bonds(s) or pool(s). For the remaining 18 IO bonds, the linkage
was incorrect and has been updated. Six of these 18 IO bonds are
IO PO bonds for which the linkage correction applied only with respect
to the PO component, where prior analysis incorrectly omitted the
PO component rating.
All 52 IO bonds in today's action reference a portion of the aggregate
collateral pool (a "sub-pool"). For 31 of the IO bonds,
the sub-pool amounts to 75% or more of the entire collateral
pool; as a result, we have treated these IO bonds as linked
to the entire pool. For nine IO bonds, the sub-pool
amounts to less than 75% of the entire collateral pool.
However, the realized loss to date (% of original balance)
of the sub-pool(s) backing these nine bonds are comparable to the
entire pool. As a result, we have also treated these nine
IO bonds as linked to the entire pool.
For the remaining 12 IO bonds that reference a sub-pool,
the sub-pool amounts to less than 75% of the entire collateral
pool and has a different realized loss to date (% of original balance)
than that of the entire pool. As a result, we used the realized
loss of the sub-pool in the analysis for today's rating actions.
Today's rating actions on the 52 IO bonds reflect the linkage reassessment,
the corrections to the linkages of 18 IO bonds, and updated performance
of the underlying collateral and bonds.
We are evaluating the remaining IO bonds on review and note that,
although a number of linkages may be corrected, this will not necessarily
lead to rating movements in all cases.

for the List of Affected Credit Ratings. This list is an integral
part of this Press Release and identifies, for each affected credit
rating, Moody's disclosures on the following items:
-Principal Methodologies
Factors that can lead to an upgrade or downgrade of the ratings:
An IO bond may be upgraded or downgraded, within the constraints
and provisions of the IO methodology, based on lower or higher realized
and expected loss due to an overall improvement or decline in the credit
quality of the reference bonds and/or pools.

REGULATORY DISCLOSURE
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

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.

support from the primary entity(ies) of this credit rating action,
and whose ratings may change as a result of this credit rating action,
