The Financial Times is reporting AIG is ignoring the new rules on derivatives.

The unit that all but destroyed AIG has failed to sign up for the overhaul of the global derivatives market which was given added impetus by the troubles at the US insurance group.

AIG confirmed that its financial products unit, whose soured bets on credit default swaps forced the company into government hands last year, did not adopt the “Big Bang” protocol that has been signed by more than 2,000 market participants.

The protocol, created under the auspices of International Swaps & Derivatives Association, is intended to make it easier for investors in the opaque market for credit derivatives to know what will happen to their contracts if debt defaults occur. It came into force on Wednesday.
