Do institutional shareholder services (ISS) corporate governance ratings reflect a company's operating performance?

Little is known about the relation between the actual governance rating received by a firm and the firm's performance. In this study, we examine the relation between the actual corporate governance rating received by a firm and the firm's performance during the years 2002–2004. We use the institutional shareholder services (ISS) corporate governance quotient (CGQ) rating of a firm's corporate governance structure and analyze this rating in relation to the firm's operating performance. We compare the institutional shareholder services’ CGQ rating to two measures of the firm's operating performance, return on assets (ROA) and return on equity (ROE). Based upon our results, we do not find statistical evidence suggesting that the firms’ operating performance is related to the firms’ ISS corporate governance rating.
