Crossed-listed foreign firms' earnings informativeness, earnings management and disclosures of corporate governance information under SOX

The passage of the Sarbanes–Oxley Act (SOX) marks the beginning of the mandatory disclosure of audit-committee composition and other corporate governance information for cross-listed foreign firms. We posit that the provisions of SOX improve the effectiveness of an independent audit committee and other corporate-governance functions in monitoring the earnings quality of cross-listed foreign firms, and we use cross-listed firms' earnings informativeness and earnings management to measure earnings quality. Our findings show earnings informativeness is significantly associated with audit-committee independence as well as with board independence in the post-SOX period. In contrast, we do not find a significant association between earnings informativeness and audit-committee independence in the pre-SOX period. Our findings also show a consistently negative association between earnings management and audit-committee independence after SOX, an association that is not found in the pre-SOX period. Similarly, a negative association between earnings informativeness and the CEO duality as the chair of the board is only found in the post-SOX period. Furthermore, our results show a positive (negative) association between earnings informativeness (earnings management) and an aggregate corporate-governance score as a measure of overall corporate-governance functions in both the pre- and post-SOX periods. Our findings on the change of magnitude in the relationship between earnings informativeness (earnings management) and corporate governance suggest that the SOX provisions improve the effectiveness of cross-listed foreign firms' corporate-governance functions in monitoring the quality of accounting earnings.
