One of the key functions of a board of directors is to oversee the CEO to ensure that shareholders are getting the most out of their investment. This idea has led to regulation such as the Sarbanes-Oxley Act (2002), as well as requirements by the NYSE and NASDAQ that boards have a majority of independent directors and that members on the audit committee have financial expertise. Such rules rest on the premise that if we can just structure the board properly, management misconduct can largely be prevented. But is this a realistic expectation for directors? Maybe not.
