The Sarbanes-Oxley Act of 2002 (Pub.L. 107-204, 116 Stat. 745, enacted July 30, 2002), also known as the 'Public Company Accounting Reform and Investor Protection Act' (in the Senate) and 'Corporate and Auditing Accountability and Responsibility Act' (in the House) and commonly called Sarbanes-Oxley, Sarbox or SOX, is a United States federal law enacted on July 30, 2002, which set new or enhanced standards for all U.S. public company boards, management and public accounting firms. It is named after sponsors U.S. Senator Paul Sarbanes (D-MD) and U.S. Representative Michael G. Oxley (R-OH).The bill was enacted as a reaction to a number of major corporate and accounting scandals including those affecting Enron, Tyco International,Adelphia, Peregrine Systems and WorldCom. These scandals, which cost investors billions of dollars when the share prices of affected companies collapsed, shook public confidence in the nation's securities markets.It does not apply to privately held companies. The act contains 11 titles, or sections, ranging from additional corporate board responsibilities to criminal penalties, and requires the Securities and Exchange Commission (SEC) to implement rulings on requirements to comply with the new law. Harvey Pitt, the 26th chairman of the SEC, led the SEC in the adoption of dozens of rules to implement the Sarbanes-Oxley Act. It created a new, quasi-public agency, the Public Company Accounting Oversight Board, or PCAOB, charged with overseeing, regulating, inspecting and disciplining accounting firms in their roles as auditors of public companies. The act also covers issues such as auditor independence, corporate governance, internal control assessment, and enhanced financial disclosure.The act was approved by the House by a vote of 423 in favor, 3 opposed, and 8 abstaining and by the Senate with a vote of 99 in favor, 1 abstaining. President George W. Bush signed it into law, stating it included "the most far-reaching reforms of American business practices since the time of Franklin D. Roosevelt."Debate continues over the perceived benefits and costs of SOX. Opponents of the bill claim it has reduced America's international competitive edge against foreign financial service providers, saying SOX has introduced an overly complex regulatory environment into U.S. financial markets. Proponents of the measure say that SOX has been a "godsend" for improving the confidence of fund managers and other investors with regard to the veracity of corporate financial statements.
