Former AIG boss Martin Sullivan and former AIG Financial Products executive Joseph Cassano are scheduled to testify on Wednesday before the US Financial Crisis Inquiry Commission. Mr Cassano led the London office of AIGFP, which put together high-risk credit default swaps as a form of insurance for mortgage-backed securities. Collateral calls on the swaps led to the near-fatal liquidity crunch at the insurer, leading to the US government bailout of the company in September 2008. Mr Sullivan was at the helm of AIG when the bulk of the swaps were sold and when the collateral calls began to threaten its survival. Also slated to appear before the commission this week are Goldman Sachs chief operating officer Gary Cohn and chief financial officer David Viniar. Goldman was a leading counterparty to AIG's swap deals and one of the leading beneficiaries of the government's bailout of AIG. Meanwhile, Senator Charles Grassley has written a letter to AIG seeking more information on generous severance packages that the company agreed last December for former chief compliance and regulatory officer Suzanne Folsom and former general counsel Anastasia Kelly. Mr Grassley said that Ms Folsom may not be eligible for more than $1m in severance pay because her severance agreement was executed after the government rescued the company. He also questioned Ms Kelly's "active role" in pushing for Ms Folsom's deal.
