Below are 10 of the largest corporate scandals in US history. Each of them had a profound impact on the nation's history.
Enron Scandal (2001):
Company: Enron Corporation
Issue: Enron executives engaged in complex accounting fraud known as "mark-to-market" accounting to hide debt and inflate profits. They created off-balance-sheet special purpose entities to keep liabilities hidden from investors.
Outcome: Enron declared bankruptcy, resulting in significant losses for shareholders and employees. Key executives, including CEO Jeffrey Skilling and CFO Andrew Fastow, were convicted and imprisoned. The scandal led to the dissolution of Arthur Andersen, one of the five largest audit and accountancy partnerships in the world, and the enactment of the Sarbanes-Oxley Act to improve corporate governance and financial disclosures.
WorldCom Scandal (2002):
Company: WorldCom, Inc.
Issue: WorldCom executives falsified financial statements by capitalizing operating expenses, inflating assets by approximately $11 billion. This made the company appear more profitable than it was.
Outcome: WorldCom filed for bankruptcy, the largest in U.S. history at the time. CEO Bernard Ebbers and other executives were convicted of fraud. The scandal led to increased regulatory scrutiny and reforms in corporate governance and accounting practices.
Bernie Madoff Ponzi Scheme (2008):
Company: Bernard L. Madoff Investment Securities LLC
Issue: Bernie Madoff orchestrated the largest Ponzi scheme in history, promising high returns to investors and using funds from new investors to pay returns to earlier investors. The scheme defrauded individuals, charities, and institutional investors out of an estimated $65 billion.

Lehman Brothers Collapse (2008):
Company: Lehman Brothers Holdings Inc.
Issue: Lehman Brothers heavily invested in subprime mortgages and complex financial instruments, leading to massive losses when the housing market collapsed. The firm was unable to secure a bailout or buyer and declared bankruptcy.

The collapse highlighted the risks of excessive leverage and inadequate risk management in the financial industry, leading to significant reforms, including the Dodd-Frank Wall Street Reform and Consumer Protection Act.

AIG Scandal (2008):
Company: American International Group (AIG)
Issue: AIG engaged in risky financial practices, particularly in the credit default swap market. When these investments soured during the financial crisis, AIG faced massive losses and liquidity problems.

HealthSouth Scandal (2003):
Company: HealthSouth Corporation
Issue: CEO Richard Scrushy and other executives falsified financial statements to meet earnings expectations, inflating earnings by $2.7 billion.
