Corporate scandals and breakdowns such as the Enron case of reputational risk in 2001 have increased calls for stronger compliance and regulations, particularly for publicly listed companies. The most significant recent statutory changes in this context have been the Sarbanes–Oxley Act developed by two U.S. congressmen, Senator Paul Sarbanes and Representative Michael Oxley in 2002 which defined significantly tighter personal responsibility of corporate top management for the accuracy of reported financial statements; and the Dodd-Frank Wall Street Reform and Consumer Protection Act.
