RATINGS RATIONALE
Moody's has affirmed the ratings on the transaction because its key transaction
metrics are commensurate with the existing ratings. While the credit
quality of the reference pool has migrated negatively as evidenced by
WARF and WARR, there have been no protection payments made to date
and our forecast of protection payment frequency and magnitude has remained
within the range of the existing ratings. The rating actions are
the result of Moody's on-going surveillance of commercial
real estate collateralized debt obligation (CRE CDO Synthetic) transactions.
Calculus CMBS Resecuritization Trust is a static synthetic credit linked
notes transaction backed by a portfolio of credit default swaps on commercial
mortgage backed securities (CMBS) (100% of the reference obligation
pool balance) issued between 2005 and 2006.
Moody's has identified the following as key indicators of the expected
loss in CRE CDO transactions: the weighted average rating factor
(WARF), the weighted average life (WAL), the weighted average
recovery rate (WARR), and Moody's asset correlation (MAC).
Moody's typically models these as actual parameters for static deals
and as covenants for managed deals.
WARF is a primary measure of the credit quality of a CRE CDO pool.
Moody's has updated its assessments for the reference obligations
it does not rate. The rating agency modeled a bottom-dollar
WARF of 4358, compared to 1628 at last review. The current
ratings on the Moody's-rated reference obligations and the assessments
of the non-Moody's rated reference obligations follow: Aaa-Aa3
and 13.7% compared to 51.9% at last review;
A1-A3 and 0.0% compare to 11.8% at
last review; Ba1-Ba3 and 17.5% compared to 9.1%
at last review; B1-B3 and 34.7% compared to
11.4% at last review; and Caa1-Ca/C and 34.1%
compared to 15.8%.
Moody's modeled a WAL of 1.0 years, compared to 1.6
years at last review The WAL is based on the look-through extension
assumptions on the loans backing the underlying CMBS reference obligations.
Moody's modeled a variable WARR of 14.1%, compared
to a mean of 24.5% at last review.
Moody's modeled a MAC of 15.7%, compared to
9.6% at last review.
Methodology Underlying the Rating Action:
The principal methodology used in these ratings was "Moody's Approach
to Rating SF CDOs" published in July 2015. Please see the Ratings
Methodologies page on www.moodys.com for a copy of this
methodology.
Factors that would lead to an upgrade or downgrade of the ratings:
The performance of the notes is subject to uncertainty, because
it is sensitive to the performance of the underlying portfolio,
which in turn depends on economic and credit conditions that are subject
to change. The servicing decisions of the master and special servicer
and surveillance by the operating advisor with respect to the collateral
interests and oversight of the transaction will also affect the performance
of the rated notes.
Moody's Parameter Sensitivities: Changes to any one or more
of the key parameters could have rating implications for some of the rated
notes, although a change in one key parameter assumption could be
offset by a change in one or more of the other key parameter assumptions.
The rated notes are particularly sensitive to changes in the ratings and
credit assessment of the reference obligations. Notching down 100%
of the reference pool by one notch would result in an average modeled
rating movement on the rated notes of zero notch downward (e.g.,
one notch down implies a ratings movement of Baa3 to Ba1). Notching
up 100% of the reference pool by one notch would result in an average
modeled rating movement on the rated notes of zero to one notch upward
(e.g., one notch up implies a ratings movement of
Baa3 to Baa2).
The primary sources of uncertainty in Moody's assumptions are the extent
of growth in the current macroeconomic environment given the weak recovery
and certain commercial real estate property markets. Commercial
real estate property values continue to improve modestly, along
with a rise in investment activity and stabilization in core property
type performance. Limited new construction and moderate job growth
have aided this improvement. However, sustained growth will
not be possible until investment increases steadily for a significant
period, non-performing properties are cleared from the pipeline
and fears of a euro area recession abate.
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.
In rating this transaction, Moody's CDOROM™ is used to model
the expected loss for each tranche. Moody's CDOROM™
is a Monte Carlo simulation tool which takes each underlying asset default
probability as input. Each underlying asset default behavior is
then modeled individually with a standard multi-factor model incorporating
both intra- and inter-industry correlation. The correlation
structure is based on a Gaussian copula. Each Monte Carlo scenario
simulates defaults and if applicable, recovery rates, to derive
losses on a portfolio. For a synthetic transaction, the model
then allocates losses to the tranches in reverse order of priority to
derive the loss on the tranches. By repeating this process and
averaging over the number of simulations, Moody's can derive
the expected loss on the tranches. For a cash transaction,
the portfolio loss, or default, distribution produced by Moody's
CDOROM™ may be input into a separate cash flow model in accordance
with its priority of payment to determine each tranche's expected
loss.
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.
