WorldCom accounting scandal was one of the largest corporate frauds in American history. In 2002, WorldCom admitted to overstating earnings by $3.8 billion by improperly accounting for line costs as capital expenditures. This was uncovered by internal auditors Cynthia Cooper and others. WorldCom's CEO Bernie Ebbers and CFO Scott Sullivan were charged and convicted for their roles in the massive fraud that ultimately led to WorldCom's bankruptcy. This scandal shook confidence in financial reporting and led to stricter Sarbanes-Oxley regulations being passed in 2002.
