New York, January 05, 2011 -- Moody's Investors Service has assigned definitive rating of Aaa (sf) to
Class A4A, A3 (sf) to Class A4B, A1 (sf) to Class A4B-1,
and A3 (sf) to Class A4B-2, issued by Morgan Stanley Re-REMIC
Trust 2010-GG10. The pass-through certificates are
collateralized by Class A-4 ("Underlying Certificate") issued by
GS Mortgage Securities Trust 2007-GG10. This transaction

US$64.0M Cl. A4B Certificate, Assigned A3 (sf)
US$32.0M Cl. A4B-1 Certificate*,
Assigned A1 (sf)
US$32.0M Cl. A4B-2 Certificate*,
Assigned A3 (sf)
The Certificates are backed by Class A-4 ("Underlying Certificate")
issued by GS Mortgage Securities Trust 2007-GG10. The Underlying
Certificate is backed by fixed rate mortgage loans secured by first liens
on commercial and multifamily properties. The Class A4A is senior
to Class A4B and Class A4B absorbs realized losses prior to A4A.
Class A4B is exchangeable for Class A4B-1 and Class A4B-2,
and vice versa. Class A4B-1 is senior to Class A4B-2
and Class A4B-2 absorbs realized losses prior to Class A4B-1.
Class A4A and Class A4B are exchangeable for Class A4 (not rated by Moody's),
and vice versa.
The methodology used in assigning the ratings is as follows: Moody's
applied ratings-specific cash flow scenarios assuming different
loss timing, recovery and prepayment assumptions on the underlying
pool of mortgages that are the collateral for the underlying CMBS transaction
through Structured Finance Workstation® (SFW), the cash flow
model developed by Moody's Wall Street Analytics. The analysis
incorporates performance variances across the different pools and the
structural features of the transaction including priorities of payment
distribution among the different tranches, tranche average life,
current tranche balance and future cash flows under expected and stressed
scenarios. In each scenario, cash flows and losses from the
underlying collateral were analyzed applying different stresses at each
rating level. The resulting ratings specific stressed cash flows
were then input into the structure of the resecuritization to determine
expected losses for each class. The expected losses were then compared
to the idealized expected loss for each class to gauge the appropriateness
of the existing rating. The stressed assumptions considered,
among other factors, the underlying transaction's collateral attributes,
past and current performance, and Moody's current negative performance
outlook for commercial real estate.
Within the resecuritization, the WAL of the Class A-4 Certificates
of GS Mortgage Securities Trust 2007-GG10 is 6.3 years assuming
a 0%/0% CDR/CPR. Expected recovery rates at the mortgage
loan level ranged from 40% to 60% with a WARR of 54.2%.
Since the ratings of the CRE CDO Certificates are linked to the rating
of the underlying CMBS certificate which in turn are linked to the performance
of the underlying commercial mortgage pool's performance, any rating
action on the underlying certificate may trigger a review of the ratings
of the Certificates. The last monitoring action placed on the Underlying
Certificate was on October 5, 2010.
Changes in any one or combination of the key parameters may have rating
implications on certain classes of rated notes. However,
in many instances, a change in key parameter assumptions in certain
stress scenarios may be offset by a change in one or more of the other
key parameters. Rated certificates are particularly sensitive to
changes in recovery rate assumptions. Holding all other key parameters
static, changing the recovery rate assumption from 50% to
27% would result in average rating movement on the junior most
Aaa (sf) rated tranche of 1 notch downward.
The performance expectations for a given variable indicate Moody's forward-looking
view of the likely range of performance over the medium term. From
time to time, Moody's may, if warranted, change these
expectations. Performance that falls outside the given range may
indicate that the collateral's credit quality is stronger or weaker than
Moody's had anticipated when the related securities ratings were issued.
Even so, a deviation from the expected range will not necessarily
result in a rating action nor does performance within expectations preclude
such actions. The decision to take (or not take) a rating action
is dependent on an assessment of a range of factors including, but
not exclusively, the performance metrics. Primary sources
of assumption uncertainty are the current stressed macroeconomic environment
and continuing weakness in the commercial real estate and lending markets.
Moody's currently views the commercial real estate market as stressed
with further performance declines expected in a majority of property sectors.
The availability of debt capital is improving with terms returning towards
market norms. Job growth and housing price stability will be necessary
precursors to commercial real estate recovery. Overall, Moody's
central global scenario remains "hook-shaped" for 2010 and 2011;
we expect overall a sluggish recovery in most of the world's largest economies,
returning to trend growth rate with elevated fiscal deficits and persistent
