When the Sarbanes-Oxley (SOX) Act was signed into law in 2002 its goal was to protect investors through increased disclosure and tougher internal controls in the wake of accounting frauds at Enron WorldCom and other U.S. companies. But on April 4 2007 the Securities and Exchange Commission announced it will revisit some of SOX’s rules. The primary focus will be the financial costs of Section 404 which requires auditors of most publicly listed companies to verify the effectiveness of internal procedures for financial reporting. Knowledge at Wharton asked accounting experts for their opinions on possible SOX revisions.
