It is generally agreed that audit committees play an important role in corporate governance, particularly in enhancing the board of directors’ effectiveness in monitoring management (Klein, 2002; Smith Report, 2003; Spira, 2003). The audit committee provides active supervision of the financial reporting process and also monitors the relationship between a firm's management and its external auditor. Hence, the audit committee plays an important role in the determination of audit fees (Abbott et al., 2003)
