Robert B. Willumstad

AIG CEO June-September 2008

Then: The former President and Chief Operating Officer at Citigroup joined AIG's board of directors in 2006, eventually presiding as its CEO when the Federal Reserve engineered an $85 billion takeover of the insurance giant, deemed "too big to fail," the day after Lehman collapsed.

Now: Willumstad, 63, rejected a $22 million severance package for his short tenure as CEO and was replaced by Edward M. Liddy. He's managing partner at Brysam Global Partners, a private equity firm he co-founded in 2007 that specializes in emerging markets.
