Williams Denies Using Strategies

LCG, May 22, 2002-Williams Cos. announced today that it did not participate in the trading strategies elaborated in the recently released Enron memos.

The Federal Energy Regulatory Commission ordered over a hundred energy traders to state whether or not they participated in twelve Enron-related trading strategies under threat of losing trading ability. On Tuesday, FERC ordered all electricity traders participating in the Western electricity market to state whether or not they participated in "round trip" trades, where electricity is sold to another party and bought back at the same price in to boost trading volume.

The natural gas pipeline operator Williams Cos., based in Tulsa, Oklahoma, said it prohibited its traders from selling power out of California for the purpose of reselling back into the state at elevated costs. Williams also asserted that only a very small percentage of trades were of the type listed in the memos.

Williams said that it will provide further information about trading in order to comply with FERC's second order, which carries a May 31 deadline.
