WorldCom internal audit uncovers capitalised line costs
In 2002, WorldCom internal audit chief Cynthia Cooper and her team, including Gene Morse, found billions in line costs (fees paid to other carriers for network access) booked as capital assets through undocumented top-side journal entries. They worked partly after hours and copied data to preserve evidence. CFO Scott Sullivan asked her to postpone the review until the next quarter, but she took the findings directly to audit committee chair Max Bobbitt. Sullivan was fired, WorldCom announced a restatement in June 2002, and the total fraud eventually reached about $11 billion.
