While most of our assignments are confidential we are particularly proud of the Devonshire decision below and it is one of the few that we can discuss (went all the way to the Supreme Court)

Barclays Bank PLC v. Devonshire Trust - CMRA helped prevail in $600 mm dispute

Lenczner Slaght, counsel to Devonshire Trust, retained CMRA to determine the valuation of 2 CSOs with stop-loss provisions in the context of the 17-month standstill that took place in the Canadian ABCP market from August 2007 through January 2009.  The extraordinary change in the mark to model value of the transactions that occurred during the standstill as a result of the financial crisis created a unique situation that required expert opinions from a practitioner's point of view on the operation of the waterfall, the impact of the collateral stop loss, who defaulted, as well as complicated and nuanced valuation issues.

CMRA was the sole expert on behalf of Devonshire whereas Barclays had 3 different experts.  CMRA submitted 2 expert reports and rebutted the reports of Barclay's 3 experts.  Leslie Rahl testified for 1 full and 2 half days at trial. Devonshire Trust prevailed, even upon appeal, ultimately recouping a total of roughly $300 mm.

CMRA Commentary on Lehman Default

Peter Niculescu, Partner, Capital Market Risk Advisors
What Red Adair is to oil and gas exploration, CMRA is to financial engineering.
— Grant's Interest Rate Observer (August 1994)

CMRA has been involved in many of the investigations and commercial disputes arising from financial meltdowns in the past 25+ years:



The [Lehman v. Citigroup] proceeding is being closely watched by the derivatives industry, which has been overhauling the way it manages counterparty risk. There are unresolved questions about whether the market’s shift to using central clearinghouses is effective, said Peter Niculescu, a partner at Capital Market Risk Advisors. The firm advises financial institutions and law firms on issues including the termination of derivatives agreements, and has represented around 15 parties with regards to their Lehman exposure...

- Bloomberg (May 2017)

Askin Capital

"In some ways there is nothing new," said Ms. Rahl, who helped investigate what went wrong at Askin." The big deals are front-page news, then they go into the recesses of people’s memories."

- The New York Times (September 2008)

In the rough-and-tumble of real-life trading, things can quickly get messy. Clearly the interests of the solvent and bankrupt parties are opposite when it comes to valuing contracts for early termination, and not surprisingly it can become contentious. Leslie Rahl, president and founder of Capital Market Risk Advisors, a risk consultancy, said that "there’s almost always a difference of opinion, breakage between the value that someone thinks they’re going to receive and what they do [receive]. Even if you have two [originally] matched trades you’re going to take them off at different prices." In other words, what looked like two sets of perfectly offsetting positions-a perfect hedge-may turn out not to offset once quotes have been obtained and the contracts terminated.

- Journal of Global Markets (Spring 2002)

Long Term Capital Management

Rahl also stressed the importance of qualitative due diligence-"eyeball to eyeball meetings"-as a key component of risk management. Rahl said this simple step is just as important as quantitative research and could have played a role in the prevention of hedge fund blowups such as the Long Term Capital Management fiasco of 1998 that tainted the industry’s reputation.

- HedgeNews (September 2002)

For now, Rahl thinks that basic checks and balances, the operational controls, are key to managing risk. Rahl should know. Rahl’s firm has surveyed major financial institutions around the world about how the Russian crisis and the LTCM problem affected risk management.

- Euromoney (November 1999)


There is no doubt that the less liquid and more exotic the derivatives position, the more subjective the estimate of value is. Clearly, that was an issue at Enron in some of their positions," said Leslie Rahl, president of Capital Market Risk Advisors Inc., a New York derivatives consulting firm.

-DowJones Newswires (May 2002)

Manhattan Investment Fund

In the wake of problems at Manhattan Investment Fund and at Heartland Advisors and the new SEC guidance on "fair value" pricing for funds, CMRA conducted an NAV/Fair Value Practices survey. Participants included hedge funds, fund of funds, mutual funds and traditional money managers.

Russian Ruble Crisis

Trading in the rapidly devaluing ruble came to a screeching halt yesterday, renewing concerns about Russia's ability to manage $40 billion in ruble-denominated debt, roughly 25 percent of which is held by foreign investors… Capital Market Risk Advisors, a New York consulting firm specializing in derivatives, estimates the Russian foreign exchange contracts and currency derivatives of one form or another currently total about $65 billion.

- The New York Times (August 1998)

Barings Bank

The collapse of a British bank [Barings Bank]… at the hands of a rogue trader in Signapore… who lost $1 billion by borrowing money to place high-risk derivatives bets in Japan… Early reports suggest Leeson was a self-contained, independent operator, violating one of the basic rules of risk management, says Leslie Rahl, principal of Capital Markets Risk Advisors, a New York firm that advises clients on derivatives investing programs.
Firms involved in high-risk trading should divide the responsibilities so there are checks and balances, she said. And they should set clear limits on the size and types of trades. Supervisors should get regular reports on what their traders are doing, she said.

- The Philadelphia Inquirer (March 1995)

Subprime/"Quant" Crisis of 2007

The panel was moderated by Leslie Rahl, an MIT graduate and the founder of Capital Market Risk Advisors. Her job is to advise companies on risk and help them understand the products quants invent. But understanding was in short supply in August [2007]. Some of the quants’ financial products had collapsed in price, with unexpected consequences in another financial sector: the trading of equities.
Was subprime the canary in the mine? Leslie Rahl, for instance, cautiously told me in a follow-up email that it is "looking more and more like the answer is yes." Many signs have suggested so, form job losses to a continuing credit drought to a weakening dollar, but that history has not yet been written.

- MIT Technology Review (November/December 2007)


"People forget that even when there's careful mark-to-market pricing, portfolio valuation does not necessarily reflect the actual price you'll get at execution," said Leslie Rahl, president of Capital Market Risk Advisors in New York. "There can be a huge difference between honest mark-to-market price and execution price."

- Lipper HedgeWorld (June 2007)

"One of the questions people have to ask themselves is, how will these synthetic instruments behave in times of stress?" says Leslie Rahl, a former Citibank risk expert who now runs Capital Market Risk Advisors, a risk consultancy in New York. Normal risk modeling only approximates normal markets-the real test comes in extreme markets. And as Rahl likes to say, "We have a once in a lifetime crisis every three or four years."

- Investment Dealers Digest (May 1995)

Bankers Trust

Gibson Greetings Inc. sued the Bankers Trust Company yesterday, accusing it of "deception, cheating and fraud" in connection with a series of financial transactions known as derivatives...
Many derivatives experts sympathize with Bankers Trust's position. "It's just human nature when a trade goes against you, you find someone to blame," said Leslie Rahl, a partner in Capital Market Risk Advisers, a derivatives consulting firm in New York."
She said a number of other companies posted losses related to derivatives but had not made them public.

- The New York Times (September 1994)

Orange County

Orange County didn’t know how much trouble its investment fund was in until… Leslie Rahl spent four weeks sorting it all out from both coasts last fall… [CMRA] uncovered the shocking $2 billion derivatives loss that forced the county into bankruptcy in December. 

- Forbes (May 1995)

A rescue mission, operating in secret in New York and Santa Ana, had hammered out a plan to restructure the county's topping investment fund and avoid default. Time was critical. The fund was hemorrhaging cash, with loses at 1.5 billion and mounting. To avoid tipping off financial markets about any plans, the team coded its cellular-phone messages: Orange County was "Oscar."

. . . The county hired Capital Market Advisors, a New York consulting firm, , last month to do some sleuthing in the portfolio. At that point, the county simply wanted to find out what the portfolio contained.

What CMRA found far worse than anyone imagined. For years, the fund's manager, County Treasurer Robert L. Citron, had been chalking up high yields by borrowing heavily from Wall Street brokers to buy even more bonds. That worked fine when interest rates were falling, but when rates turned back up this year, losses mounted. Instead of calling it quits, Mr. Citron doubled up.

. . . On Friday, the CMRA consultants contacted every Wall Street firm that had avoided doing business with Mr. Citron to explore the fund's option and negotiate a workout. Four stepped up: J.P. Morgan & Co., Goldman Sachs & Co., Salomon Inc. and Swiss bank Corp. . .
