The Sarbanes-Oxley Act of 2002 (SOX) was passed due to the accounting scandals at Enron, WorldCom, Global Crossing, Tyco and Arthur Andersen, that resulted in billions of dollars in corporate and investor losses. These huge losses negatively impacted the financial markets and general investor trust. SOX mandates a wide-sweeping accounting framework for all public companies doing business in the United States.
SOX itself is organized into eleven sections, but sections 302, 404, 401, 409, 802 and 906 are the most important in terms of compliance. More specifically, SOX established new accountability standards for corporate boards and auditors, established a Public Company Accounting Oversight Board (PCAOB) under the Security and Exchange Commission (SEC), and specified civil and criminal penalties for noncompliance.
