A federal judge gave final approval Wednesday for three more banks to pay $6.6 billion to settle civil claims that they helped Enron Corp. manipulate earnings.

U.S. District Judge Melinda Harmon in Houston approved the deals with the Canadian Imperial Bank of Commerce, JPMorgan Chase & Co. and Citigroup Inc. Her ruling came as a jury in another courtroom continued to deliberate the fate of Enron founder Kenneth Lay and former chief executive Jeffrey Skilling in a criminal fraud and conspiracy trial.
