This document summarizes a case study on the collapse of Enron Corporation. It provides background on Enron's rapid growth and success in the late 1990s as an energy company, but also describes how much of its reported profits were fictional due to fraudulent accounting practices. The summary outlines some of the major ethical issues involved, including accounting fraud, misleading financial disclosures, excessive executive compensation tied to stock performance, lack of oversight of risky derivatives trading, and 401k retirement plans that were heavily invested in Enron stock. The downfall of Enron in 2001 as the largest corporate bankruptcy at the time had wide-ranging impacts and led to new regulations and legislation to reform corporate accounting and governance.
