AIG was effectively the largest unfunded investor in the super-senior tranches of the Abacus 2004 deal.
This means that AIG:
A: Was committed to buy defaulted collateral from the CDO to make the short investors whole.
B: Effectively would sell the underlying subprime collateral as the mortgages began to default.
C: Would have to pay the short investors annual premiums
D: Owned all of the underlying subprime collateral of the Abacus CDO
