WorldCom Inc.
The $11 Billion Accounting Fraud
Filed: July 21, 2002
WorldCom's $11 billion accounting fraud surpassed Enron as the largest in U.S. history (until Madoff). CEO Bernie Ebbers turned a small Mississippi long-distance reseller into the second-largest telecom company in America — then used fraudulent accounting to hide its collapse when the dot-com bubble burst.
The Numbers

Root Cause Analysis
What actually killed WorldCom Inc..
- ▸ Capitalization of operating expenses: booking $3.8B in line costs as capital investment over 5 quarters
- ▸ Acquisition-fueled growth masked organic decline — when acquisitions stopped, growth disappeared
- ▸ CEO Bernie Ebbers' personal margin calls on WorldCom stock created incentive to prop up share price
- ▸ Board approved $400M in personal loans to Ebbers to cover margin calls
- ▸ Arthur Andersen (again) signed off on fraudulent accounting
Lessons Learned
What investors, executives, and regulators should take away.
- ! When a company grows entirely through acquisition, ask: what's the organic growth rate?
- ! Capitalizing operating expenses is Accounting 101 fraud — it should never survive an audit
- ! A CEO taking company loans to meet personal margin calls is a screaming conflict of interest
- ! Internal whistleblowers (Cynthia Cooper) stopped this fraud — invest in internal audit
