Family control, board independence and earnings management: Evidence based on Hong Kong firms

In this study, we document that independent corporate boards of Hong Kong firms provide effective monitoring of earnings management, which suggests that despite differences in institutional environments, corporate board independence is important to ensure high-quality financial reporting. The findings also show that the monitoring effectiveness of corporate boards is moderated in family-controlled firms, either through ownership concentration or the presence of family members on corporate boards. The results based on firms reporting small earnings increases provide additional support for our finding that the monitoring effectiveness of independent corporate boards is moderated in family-controlled firms.     

Does confucianism influence corporate earnings management?

This paper investigates the effect of Confucianism on corporate earnings management. Using a sample of Chinese listed firms from 2007 to 2017, we find that corporate earnings management is negatively associated with the popularity of Confucianism. Our findings also reveal that the effect of Confucianism is particularly strong among firms characterized with weaker internal control and external supervision or located in areas with lower level of marketization. Our findings shed important light on how culture improves the quality of financial reporting in emerging markets.     

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.     

Board of director characteristics and earnings quality surrounding implementation of a corporate governance code in Mexico

Mexico recently enacted a corporate governance code. One objective of the code is to improve board of director oversight and to reveal more transparent information to shareholders by including detailed information regarding the structure of the board and its functions. Research in the U.S. has documented improvement in earnings quality associated with board characteristics. Whether or not board characteristics are associated with improved earnings quality in Mexico is questionable given the business environment in which firms operate, characterized by controlling family ownership and weak legal protection of property rights. The purpose of this study is to investigate whether or not board characteristics other than compliance with board independence (board composition disclosure, family concentrated ownership and shared-directors) are associated with the improvement in earnings quality found in previous research. Earnings quality is measured using income smoothing, timely loss recognition and conditional accruals. We find firms that do not have concentrated family ownership or share directors have greater increases in earnings quality than firms that have concentrated family ownership or share directors. We conclude that applying board-level corporate governance reforms, without considering cultural and legal environments, may limit the desired effects of the change.     

Reversing an impairment loss and earnings management: The role of corporate governance

This paper examines whether the reversal of a previously recognized impairment loss provides an opportunity for earnings management, and whether such behavior is associated with managers' incentives. It also examines whether a corporate-governance mechanism can mitigate this behavior. Since 2005, listed companies in Taiwan have been required to comply with accounting standards, equivalent to International Accounting Standards (IAS) No. 36 “Impairment of Assets,” which allow reversals of asset-impairment losses. Data on a sample of 55 firms that reversed impairment losses between 2005 and the first quarter of 2007 were matched by industry and size with 55 control firms. Empirical results show that firms recognizing more impairment losses are more likely to reverse impairment losses when doing so would avoid an earnings decline in a subsequent period, which is consistent with the “cookie jar” reserve hypothesis. We also show that such behavior is more pronounced for firms with higher debt ratios, consistent with earnings management being associated with the incentive to avoid violation of debt covenants. However, an effective corporate governance mechanism could mitigate such behavior. Our study may contribute to the debate on global convergence with IFRS, especially convergence between IFRS and U.S. GAAP with respect to the “Impairment of Assets,” by providing a rationale for the latter's prohibition of reversals. It may also contribute to the corporate-governance literature by showing the effect of governance mechanisms on deterring earnings management.     

International comparative analysis of the association between board structure and the efficiency of value added by a firm from its physical capital and intellectual capital resources

This study investigates the link between corporate board features and corporate performance for a sample of 286 publicly traded firms from South Africa (84 firms), Sweden (94 firms), and the UK (108 firms). Corporate board features considered are board composition, inside director ownership, duality and board size. In contrast to prior literature, performance is defined as the efficiency of value added (VA) rather than in financial terms. Further, the analysis examines the association between board features and efficiency of VA and each of the firm's physical capital (PC) and intellectual capital (IC), respectively. Finally, the present study analyzes the association between board features and corporate performance conjointly. Comparable to general findings from studies using U.S. data, the empirical analysis as a whole did not discern consistent significant link between the four board features and corporate performance across the three nations. However, individual board features are found to influence corporate performance in isolated cases. Overall, results provide evidence that even under different sociopolitical and economic conditions, governance needs vary across firms. Consequently, these findings do not lend support to the notion that uniform board structures should be mandated.     

Does compliance with corporate governance codes help to mitigate financial distress?

This paper analyzes whether the compliance with corporate governance codes helps to mitigate the financial distress of firms. We examine three different levels of compliance: overall compliance, the compliance with the recommendations regarding the board of directors and the compliance with the recommendations on board subcommittees. Our results reveal that only the fulfillment with the recommendations about the board of directors leads to a reduction in the likelihood of financial distress. These findings extend the academic debate concerning the role of governance codes and their impact on firm outcomes, and have practical implications for both professionals and firms. Moreover, our findings emphasize the need to distinguish between the different types of recommendations to investigate the effects of these codes. In addition, the results can be useful for policymakers in the configuration of new requirements and recommendations regarding corporate governance structures. Furthermore, our results contribute to the literature, delving into the determinants of the financial distress of firms.     

Corporate governance and earnings management at large U.S. bank holding companies

This paper examines whether corporate governance mechanisms affect earnings and earnings management at the largest publicly traded bank holding companies in the United States. We first find that performance, earnings management, and corporate governance are endogenously determined. Thus, OLS estimation can lead to biased coefficients and a simultaneous equations approach is used. We find that CEO pay-for-performance sensitivity (PPS), board independence, and capital are positively related to earnings and that earnings, board independence, and capital are negatively related to earnings management. We also find that PPS is positively related to earnings management. Finally, PPS and board independence are positively related and the relationship is bidirectional. While both PPS and board independence are associated with higher earnings, our results indicate that more independent boards appear to constrain the earnings management that greater PPS compels.     

The association between corporate governance and earnings quality: Further evidence using the GOV-Score

This paper reexamines the relation between corporate governance and quality of earnings using a summary governance measure. Prior research has used many surrogates for corporate governance including size and composition of board of directors, existence and composition of audit committee, and extent of institutional ownership. However, the criticism of the extant research has been that corporate governance comprises many facets and is not uni-dimensional. In this study we fill this void by using the Gov-Score developed by Brown and Caylor [Brown, D., and Caylor, M.L., (2006). Corporate governance and firm valuation. Journal of Accounting and Public Policy 25, 409-434.] to measure corporate governance. In the post-Sarbanes-Oxley period, we find evidence of a significant inverse relationship, namely higher levels of corporate governance are associated with lower absolute discretionary accruals and higher quality of earnings. Furthermore, our results suggest that only firms in the highest category of corporate governance experience significantly improved quality of earnings. Finally, as a test of robustness, we document that corporate governance is negatively associated with small earnings surprises. This implies that firms with weak corporate governance are more likely to manage earnings in order to meet or beat analyst forecasts.     

Internal governance structures and earnings management

This paper investigates the role of a firm's internal governance structure in constraining earnings management. It is hypothesized that the practice of earnings management is systematically related to the strength of internal corporate governance mechanisms, including the board of directors, the audit committee, the internal audit function and the choice of external auditor. Based on a broad cross‐sectional sample of 434 listed Australian firms, for the financial year ending in 2000, a majority of non‐executive directors on the board and on the audit committee are found to be significantly associated with a lower likelihood of earnings management, as measured by the absolute level of discretionary accruals. The voluntary establishment of an internal audit function and the choice of auditor are not significantly related to a reduction in the level of discretionary accruals. Our additional analysis, using small increases in earnings as a measure of earnings management, also found a negative association between this measure and the existence of an audit committee.     

Board composition,grey directors and corporate failure in the UK

This study examines the effect of board composition on the likelihood of corporate failure in the UK. We consider both independent and non-independent (grey) non-executive directors (NEDs) to enhance our understanding of the impact of NEDs' personal or economic ties with the firm and its management on firm performance. We find that firms with a larger proportion of grey directors on their boards are less likely to fail. Furthermore, the probability of corporate failure is lower both when firms have a higher proportion of grey directors relative to executive directors and when they have a higher proportion of grey directors relative to independent directors. Conversely, there is a positive relationship between the likelihood of corporate failure and the proportion of independent directors on corporate boards. The findings discussed in this study support the collaborative board model and the view that corporate governance reform efforts may have over emphasised the monitoring function of independent directors and underestimated the benefits of NEDs' affiliations with the firm and its management.
