This paper investigates the economic consequences of the Sarbanes-Oxley Act through a study of market reactions to legislative events related to the Act. I find that the cumulative abnormal return around all legislative events leading to the passage of the Act is significantly negative. I then examine the private benefits and costs of major provisions of the Act by investigating the cross-sectional variation in market reactions to the rulemaking events. Regression results are consistent with the hypothesis that shareholders consider both the restriction of nonaudit services and the provisions to enhance corporate governance costly to business. The results also show that Section 404 of SOX, which mandates an internal control test, imposes significant costs on firms on average.
