Default Swap Reforms Roiled as Aiful Tests Settlement

By Abigail Moses and Shannon D. Harrington

Nov. 27 (Bloomberg) -- Wall Street’s system for determining payments on derivatives linked to the debt of defaulted companies is showing cracks less than a year after securities firms changed practices to avoid “Draconian” regulation.

Credit-default swaps tied to Thomson SA, the Paris-based owner of film processor Technicolor Inc., paid some holders 30 percent less than those with contracts expiring a day later. In Japan, owners of swaps on Aiful Corp. haven’t been compensated, though one of its banks said the consumer lender skipped loan repayments. Dealers can’t agree whether to reimburse investors in Mexican cement maker Cemex SAB’s debt swaps.
