1Roles and the dated record

analysisMcMahon was part of Enron’s treasury and finance leadership before becoming CFO in the final weeks before bankruptcy. The Powers inquiry recorded a disputed March 2000 conversation in which he said he warned Skilling about pressure associated with LJM. The report did not resolve all differences between their accounts. 1 2

analysisIn June 2007 McMahon agreed to settle SEC allegations concerning the Nigerian barge transaction and rating-agency disclosures. Without admitting or denying the allegations, he accepted an injunction, five-year officer-and-director bar and $300,000 in combined disgorgement, interest and penalty. The release said court approval was still required; its accounting suspension allowed reapplication after three years. These terms were a distinct resolution of his case. 1
