This document provides an overview of the accounting fraud scandal at WorldCom that led to its bankruptcy filing in 2002. It describes how WorldCom improperly recorded $3.8 billion in capital expenditures as expenses over five quarters between 2001-2002 in order to artificially inflate profits. This was uncovered in June 2002 and had severe consequences, as WorldCom filed for Chapter 11 bankruptcy protection shortly after, listing over $100 billion in assets but $41 billion in debt. The document examines who was responsible and the impact on the telecommunications industry.
