Reliant Resources Says Two Executives Quit

Reliant Resources Inc. said two of its top energy-trading executives resigned after the company revealed sham electricity and natural gas transactions that inflated its business.

Joe Bob Perkins, president of the wholesale energy business, and Shahid Malik, head of wholesale trading, quit, a spokeswoman said.

Separately, CMS Energy Corp., which made sham trades with Reliant, said the head of its energy-marketing unit, Tamela W. Pallas, quit.
