On July 30, 2002, the American Congress passed the Sarbanes-Oxley (SOX) act to improve corporate disclosure accountability, transparency, and corporate governance across a public company. The SOX act is intended to protect the shareholders and the general public from business accounting errors and fraudulent activities. The act was passed in a reaction to a series of financial scandals that occurred during 2000-2002 period such as Enron, Tyco, and WorldCom.
