The article describes and summarizes five studies that examined whether the landmark Sarbanes-Oxley Act of 2002 (SOX) was beneficial or not to financial reporting. The U.S. Congress is stated to have passed the legislation on July 25, 2002 in reaction to a series of financial accounting scandals involving such companies as Enron and WorldCom, as well as the demise of the accounting firm Arthur Andersen LLP. The author asserts that all five of the studies provide evidence of a significant improvement in the financial reporting environment since SOX.
