The Sarbanes-Oxley Act of 2002 was passed in response to major corporate and accounting scandals to increase corporate accountability and protect investors. It established new or enhanced standards for all U.S. public company boards, management, and public accounting firms. Key provisions included requiring CEOs and CFOs to certify the accuracy of financials, increasing penalties for financial misconduct, and strengthening auditor independence and corporate governance. The Act aimed to rebuild investor confidence in the securities markets.
