How a small unit of AIG in London blew up the company

Although America’s housing collapse is often cited as having caused the crisis, the system was vulnerable because of intricate financial contracts known as credit derivatives, which insure debt holders against default. They are fashioned privately and beyond the ken of regulators — sometimes even beyond the understanding of executives peddling them.

Originally intended to diminish risk and spread prosperity, these inventions instead magnified the impact of bad mortgages like the ones that felled Bear Stearns and Lehman and now threaten the entire economy.

In the case of A.I.G., the virus exploded from a freewheeling little 377-person unit in London, and flourished in a climate of opulent pay, lax oversight and blind faith in financial risk models. It nearly decimated one of the world’s most admired companies, a seemingly sturdy insurer with a trillion-dollar balance sheet, 116,000 employees and operations in 130 countries.

“It is beyond shocking that this small operation could blow up the holding company,” said Robert Arvanitis, chief executive of Risk Finance Advisors in Westport, Conn. “They found a quick way to make a fast buck on derivatives based on A.I.G.’s solid credit rating and strong balance sheet. But it all got out of control.”

The insurance giant’s London unit was known as A.I.G. Financial Products, or A.I.G.F.P. It was run with almost complete autonomy, and with an iron hand, by Joseph J. Cassano, according to current and former A.I.G. employees.

A onetime executive with Drexel Burnham Lambert — the investment bank made famous in the 1980s by the junk bond king Michael R. Milken, who later pleaded guilty to six felony charges — Mr. Cassano helped start the London unit in 1987.

The unit became profitable enough that analysts considered Mr. Cassano a dark horse candidate to succeed Maurice R. Greenberg, the longtime chief executive who shaped A.I.G. in his own image until he was ousted amid an accounting scandal three years ago.

But last February, Mr. Cassano resigned after the London unit began bleeding money and auditors raised questions about how the unit valued its holdings. By Sept. 15, the unit’s troubles forced a major downgrade in A.I.G.’s debt rating, requiring the company to post roughly $15 billion in additional collateral — which then prompted the federal rescue.

...

When Mr. Cassano first waded into the derivatives market, his biggest business was selling so-called plain vanilla products like interest rate swaps. Such swaps allow participants to bet on the direction of interest rates and, in theory, insulate themselves from unforeseen financial events.

Ten years ago, a “watershed” moment changed the profile of the derivatives that Mr. Cassano traded, according to a transcript of comments he made at an industry event last year. Derivatives specialists from J. P. Morgan, a leading bank that had many dealings with Mr. Cassano’s unit, came calling with a novel idea.

Morgan proposed the following: A.I.G. should try writing insurance on packages of debt known as “collateralized debt obligations.” C.D.O.’s. were pools of loans sliced into tranches and sold to investors based on the credit quality of the underlying securities.

The proposal meant that the London unit was essentially agreeing to provide insurance to financial institutions holding C.D.O.’s and other debts in case they defaulted — in much the same way some homeowners are required to buy mortgage insurance to protect lenders in case the borrowers cannot pay back their loans.

Under the terms of the insurance derivatives that the London unit underwrote, customers paid a premium to insure their debt for a period of time, usually four or five years, according to the company. Many European banks, for instance, paid A.I.G. to insure bonds that they held in their portfolios.

Because the underlying debt securities — mostly corporate issues and a smattering of mortgage securities — carried blue-chip ratings, A.I.G. Financial Products was happy to book income in exchange for providing insurance. After all, Mr. Cassano and his colleagues apparently assumed, they would never have to pay any claims.

Since A.I.G. itself was a highly rated company, it did not have to post collateral on the insurance it wrote, analysts said. That made the contracts all the more profitable.

These insurance products were known as “credit default swaps,” or C.D.S.’s in Wall Street argot, and the London unit used them to turn itself into a cash register.

The unit’s revenue rose to $3.26 billion in 2005 from $737 million in 1999. Operating income at the unit also grew, rising to 17.5 percent of A.I.G.’s overall operating income in 2005, compared with 4.2 percent in 1999.

Profit margins on the business were enormous. In 2002, operating income was 44 percent of revenue; in 2005, it reached 83 percent.

Mr. Cassano and his colleagues minted tidy fortunes during these high-cotton years. Since 2001, compensation at the small unit ranged from $423 million to $616 million each year, according to corporate filings. That meant that on average each person in the unit made more than $1 million a year.

In fact, compensation expenses took a large percentage of the unit’s revenue. In lean years it was 33 percent; in fatter ones 46 percent. Over all, A.I.G. Financial Products paid its employees $3.56 billion during the last seven years.

The failure of all these highly intelligent people to understand the risks in these investments is truly astounding. Most thought they were dealing with high quality investments with limited risks. There was the failure to understand the risks as well as the additional risks compounded by the leverage in the transactions.
