Abstract: This paper examines the longer-term corporate governance, compliance and valuation implications of Sarbanes-Oxley Act of 2002 (SOX) on US and foreign firms. Significant benefits of SOX are shown, particularly for small companies and US-traded foreign companies, although disproportional compliance costs are shown for the former. Firms that are less compliant with the legislation experience relatively higher abnormal returns, supporting the hypothesis that relaxing compliance constraints is value enhancing. Long-term abnormal returns are negatively related to board independence and CEO duality, but are positively related to the ownership by insiders and institutional investors.
