One of the plays that would see Goldman through the crisis was the big short position it had built, betting against mortgage-backed securities. A big piece of that bet was placed by buying CDS from AIG. Already by June 30, 2008, Goldman had called $7.5 billion in collateral. When AIG was downgraded on September 15, there was a new surge in margin calls. Of the total claim against AIG, which now topped $32 billion, Goldman Sachs and its partner Société Générale accounted for $19.8 billion.
