The Citigroup settlement in the that case became a blueprint for other banks to reach settlements. In the WorldCom litigation, J.P. Morgan paid $2 billion to settle claims against it. J.P. Morgan's payout in WorldCom ranked right behind Citigroup. In Enron, it's believed that J.P. Morgan's level of exposure is roughly equal to that of Citigroup, because both banks were the primary lenders to Enron. In 2002, J.P. Morgan paid $135 million to the Securities and Exchange Commission to settle allegations it disguised loans to Enron as trading proceeds. In a similar settlement, Citigroup paid $101 million to the SEC. Other banks that have paid big regulatory fines for their role in the Enron debacle include Merrill and CIBC.
