The Sarbanes-Oxley Act (SOX) was passed in 2002 in response to major corporate accounting scandals to increase transparency and accuracy in financial reporting. SOX established new or expanded standards for all U.S. public company boards, management, and public accounting firms. Key provisions addressed auditor independence, corporate governance, internal control assessment, and financial disclosure. SOX also strengthened criminal penalties for violation of securities law and increased criminal sentences for white-collar crimes like fraud.
