Summary of the Interview or Submission:
Ellen Duke is currently a managing director at Lehman holding and is responsible for winding
down its derivative positions. She was a mortgage ABS trader for thirteen years prior to her risk
role.
Murray Barnes and Dominic Wallace were responsible for CDOs and the correlation desk
(synthetic CDOs) and Smillie had Global Securitized Markets. All reported into Ms. Duke and
all four of them met every Monday to discuss both sides of the house together. Mr. Barnes and
Mr. Smillie sat in offices next to each other and talked “all the time” to each other about Global
Securitized Markets and Global Structured Credit Products. Ms. Duke remembers in September
becoming aware that Global Securitized Markets (GSM) was de-levering subprime and Global
Structured Credit Products (GSCP) was doing more. In retrospect they were “seduced by the
structuring and failed to look at the underlying collateral.” She conceded looking back that the
analysis of CDO structuring shouldn’t have been different than RMBS securitization regarding
evaluation of subprime as collateral.
In addition to her weekly (Monday) independent risk team meetings, there were weekly
(Tuesday) meetings of the Citi Markets & Banking (CMB) risk committee, which included Ms.
Duke, Mr. Barnes, Mr. Wallace, and Mr. Smillie from Independent Risk and Thomas Maheras
and others from the business side, as well as representatives from Finance and Audit—about

for the weekly “Risk Committee Package,” which contained a cover sheet with attendees and
agenda. It always contained limits and any authorized or unauthorized limit increases, VAR and
risk factors in each business, concentrated exposures, and a weekly narrative commentary.
Ms. Duke outlined the three areas of risk that Independent risk evaluated: credit risk; market risk,
and operational risk (reputational, etc). I asked which bucket liquidity risk fell in and she said it
was separately evaluated outside of Independent Risk and was the express responsibility of
Finance and the CFO: the Asset Liability Management Committee (ALCO) was charged with
evaluating liquidity risk (Cliff Verron/Scott Freidenrich). Pricing and marking positions was the
responsibility of traders, subject to Finance validation and, if asked, input by Independent Risk
(Murray Barnes/ Dominic Wallace did have input variously).
She recalled one time in 2003 or 2004 that the super seniors made the “Top Ten Risks” list
specifically because of the size of the position, but ultimately all became comfortable with the
super seniors because of their overcollateralization. The Top Ten list was the annual compilation
that Business made to Independent Risk.
Ms. Duke never had concerns regarding CDO, RMBS, or the correlation businesses until the first
week in July—she had a clear recollection of being in Florida on vacation and getting a call over
July 4 and spending her vacation on the phone talking about pending losses in RMBS/CDOs and
the correlation desk.
One of Independent Risk’s responsibilities was to validate all models—there was frequently a
backlog of business models that Independent Risk hadn’t validated sometime in 2003 or 2004.
Ms. Duke put a process in place to prioritize model validations—generally desks could trade up
to a set limit/set times prior to full validation or approval by Independent Risk.
She recalled one instance in August or September of 2007 where validation approval was an
issue. The business side was creating a different model to value the super seniors and it came to
her attention that the prior super-senior model had not been validated by Independent Risk. At
the end of the day, she, Mr. Barnes, and Mr. Wallace were overruled by Mr. Bushnell and others
regarding what house price appreciation inputs should go into the model. However, Ms. Duke
was satisfied that there was a full vetting process even though she wanted a more conservative
input and was overruled. It was already August by then, and the difference was approximately
400 million in markdowns. She believes that the desk may have still had opportunity to more
effectively hedge (shorting the ABX) if the more conservative models had been adopted at that
point
Until July 2007, Ms. Duke viewed the possibility of liquidity puts being triggered as “extremely
remote.”
Ms. Duke has no knowledge of SIVs (would have been Patrick Ryan), no recollection of
liquidity puts prior to July 2007, and was not aware of the surveillance unit in GSM (nor did she
know who Susan Mills is).
