On July 30, 2002, President Bush signed into law the Sarbanes-Oxley Act of 2002 (the S-O Act). The S-O Act, which had been approved by a unanimous Senate and a nearly unanimous House, attempts to address many of the accounting and corporate governance issues raised by the collapse of Enron, Global Crossing and WorldCom. A number of critically important provisions of the S-O Act became effective on the date of enactment, with others to become effective over the next several months.
