According to Moody's, the rating actions taken on the notes
result primarily from improvement in the credit quality of the underlying
portfolio and an increase in the transaction's overcollateralization
ratios since the rating action in June 2009.
Improvement in the credit quality is observed through an improvement in
the average credit rating (as measured by the weighted average rating
factor) and a decrease in the proportion of securities from issuers rated
Caa1 and below. In particular, as of the latest trustee report
dated December 31, 2010, the weighted average rating factor
is currently 2504 compared to 2772 in the May 2009 report, and securities
rated Caa1/CCC+ or lower make up approximately 6.7%
of the underlying portfolio versus 13.1% in May 2009.
Additionally, defaulted securities total about $2 million
of the underlying portfolio compared to $44 million in May 2009.
The overcollateralization ratios of the rated notes have also improved
since the rating action in May 2009. The Class A, Class B,
Class C, Class D and Class E overcollateralization ratios are reported
at 131.93%, 123.46%, 115.54%,
109.41% and 106.19%, respectively,
versus May 2009 levels of 124.07%, 116.25%,
108.93%, 103.24% and 100.25%,
respectively, and all related overcollateralization tests are currently
in compliance. Moody's also notes that the Class E Notes
are no longer deferring interest and that all previously deferred interest
has been paid in full.
Due to the impact of revised and updated key assumptions referenced in
"Moody's Approach to Rating Collateralized Loan Obligations" and
"Annual Sector Review (2009): Global CLOs," key
model inputs used by Moody's in its analysis, such as par,
weighted average rating factor, diversity score, and weighted
average recovery rate, may be different from the trustee's reported
numbers. In its base case, Moody's analyzed the underlying
collateral pool to have a performing par and principal proceeds balance
of $715 million, defaulted par of $8.2 million,
a weighted average default probability of 28.02% (implying
a WARF of 3521), a weighted average recovery rate upon default of
42.85%, and a diversity score of 60. These
default and recovery properties of the collateral pool are incorporated
in cash flow model analysis where they are subject to stresses as a function
of the target rating of each CLO liability being reviewed. The
default probability is derived from the credit quality of the collateral
pool and Moody's expectation of the remaining life of the collateral
pool. The average recovery rate to be realized on future defaults
is based primarily on the seniority of the assets in the collateral pool.
In each case, historical and market performance trends and collateral
manager latitude for trading the collateral are also factors.
Duane Street CLO IV, Ltd., issued in August 2007,
is a collateralized loan obligation backed primarily by a portfolio of
senior secured loans.
The principal methodologies used in these ratings were "Moody's Approach
to Rating Collateralized Loan Obligations" published in August 2009 and
"Using the Structured Note Methodology to Rate CDO Combo-Notes"
published in February 2004.
Moody's Investors Service did not receive or take into account a
third-party due diligence report on the underlying assets or financial
instruments related to the monitoring of this transaction in the past
Moody's modeled the transaction using the Binomial Expansion Technique,
as described in Section 184.108.40.206 of the "Moody's Approach
to Rating Collateralized Loan Obligations" rating methodology published
in August 2009.
In addition to the base case analysis described above, Moody's also
performed a number of sensitivity analyses to test the impact on all rated
notes, including the following:
1. Various default probabilities to capture potential defaults
in the underlying portfolio
2. A range of recovery rate assumptions for all assets to capture
variability in recovery rates.
Below is a summary of the impact of different default probabilities (expressed
in terms of WARF levels) on all rated notes (shown in terms of the number
of notches' difference versus the current model output, where
a positive difference corresponds to lower expected loss), assuming
that all other factors are held equal:
Moody's Adjusted WARF -- 20% (2817)
Class A-1T: +2
Class A-1R: +2
Class B: +2
Class C: +2
Class D: +4
Class E: +2
Class F: +2
Moody's Adjusted WARF + 20% (4225)
Class A-1T: -2
Class A-1R: -2
Class B: -2
Class C: -2
Class D: -3
Class E: -2
Class F: -2
Below is a summary of the impact of different recovery rate levels on

Moody's notes that this transaction is subject to a high level of
macroeconomic uncertainty, as evidenced by 1) uncertainties of credit
conditions in the general economy and 2) the large concentration of speculative-grade
debt maturing between 2012 and 2014 which may create challenges for issuers
to refinance. CDO notes' performance may also be impacted
by 1) the manager's investment strategy and behavior and 2) divergence
in legal interpretation of CDO documentation by different transactional
parties due to embedded ambiguities.
Sources of additional performance uncertainties are described below:
1) Long-dated assets: The presence of assets that mature
beyond the CLO's legal maturity date exposes the deal to liquidation
risk on those assets. Moody's assumes an asset's terminal
value upon liquidation at maturity to be equal to the lower of an assumed
liquidation value (depending on the extent to which the asset's
maturity lags that of the liabilities) and the asset's current market
2) Weighted average life: The notes' ratings are sensitive
to the weighted average life assumption of the portfolio, which
may be extended due to the manager's decision to reinvest into new
issue loans or other loans with longer maturities and/or participate in
amend-to-extend offerings. Moody's tested for
a possible extension of the actual weighted average life in its analysis.
3) Other collateral quality metrics: The deal is allowed to reinvest
and the manager has the ability to deteriorate the collateral quality
metrics' existing cushions against the covenant levels. Moody's
analyzed the impact of assuming lower of reported and covenanted values
for weighted average rating factor, weighted average spread,
weighted average coupon, and diversity score. However,
as part of the base case, Moody's considered spread and diversity
levels higher than the covenant levels due to the large difference between
the reported and covenant levels.
