The function of boards of directors and supervisors is the core of the corporate governance. The directors' expertise can strengthen the administrative mechanism, and in-crease financial statement's credibility. The restatement does not equal to a financial statement fraud. However, it will mislead the financial statement users and make them do improper decisions. We examine a sample of 34 restatements on listed company in the period 2003-2006, together with matched pairs control groups of similar industry and time. Our research find out that the boards of directors and supervisors who have financial background have significant negative relationship with restatement, and the existence of other jobs held by directors and supervisors has significant positive relationship with restatement. The results support directors' expertise can reduce the incidence of restatement.
