Williams Cos. and CFTC Reach Settlement over Natural Gas Trading Allegations

LCG, July 30, 2003Williams Cos. and its electricity trading subsidy came to a $20 million settlement with the Commodity Futures Trading Commission over allegedly manipulative published trading information.

Last year, Williams publicly and voluntarily reported that some of its non-managerial employees had submitted inaccurate natural gas trading data to industry publications. These employees were put on leave and eventually dismissed.

The Commission alleges that Williams Cos. reported falsified price and volume information to industry publications, resulting in the creation of unrealistic indices. These published indices were, in turn, used by others to gauge appropriate prices for wholesale natural gas contracts.

While Williams Cos. and its unit Williams Energy Marketing & Trading Co. agreed to pay $20 million to the CFTC, the companies admit no wrongdoing. The Commission announced the settlement yesterday.

Oklahoma-based Williams Cos. has ended its practice of providing data to industry publications and has moved its focus from trading to its core, natural gas businesses.
