WorldCom: How Internal Auditors Uncovered a $3.8 Billion Fraud

What would you do if the evidence pointed to the executives above you? In 2002, Cynthia Cooper and her internal audit team pursued accounting questions that helped expose the WorldCom scandal. The initial disclosure involved approximately $3.8 billion in improper transfers from expenses to assets. Further investigations revealed a wider fraud. This documentary explores how the accounting worked, how the auditors pursued the evidence, and what the case teaches us about management override, professional skepticism, and corporate governance. In this video: • The pressure to meet financial expectations • Line costs and improper capitalization • Why approval does not replace supporting evidence • Cynthia Cooper’s team and the investigation • Escalation to the audit committee • Six practical lessons for internal auditors and business leaders The simplified accounting example in this video is illustrative and does not represent WorldCom’s actual figures. Presented by Salih Ahmed Islam, CIA, GRCP.
