The Effect of Board Diversity on Earnings Quality: An Empirical Study of Listed Firms in Vietnam

Previous studies have established that firms’ effectiveness can differ based on the differences among directors within a board, and between boards. However, studies have yet to establish the effectiveness of the diverse attributes of the board on firms’ quality of earnings in an emerging market setting such as Vietnam. This study investigates the effect of board diversity on earnings quality in a sample of Vietnamese listed firms. The two dimensions of board diversity measures in this study cover a wide range of structural and demographic attributes of board of directors, using a diversity‐of‐boards index (dissimilarities among firm boards, i.e., board structure) and a diversity‐in‐boards index (dissimilarities among directors within a board, i.e., demographic attributes of board members). Earnings quality is an aggregate measure compiled from four accounting‐based measures of earnings quality: accruals quality, earnings persistence, earnings predictability and earnings smoothness. We find a significant, positive linear relationship between diversity of boards and earnings quality, while the relationship between diversity in boards and earnings quality is non‐linear, with a U‐shaped curve.     

Non-GAAP earnings and board independence

We examine the association between board independence and the characteristics of non-GAAP earnings. Our results suggest that companies with less independent boards are more likely to opportunistically exclude recurring items from non-GAAP earnings. Specifically, we find that exclusions from non-GAAP earnings have a greater association with future GAAP earnings and operating earnings when boards contain proportionally fewer independent directors. Consistent with the association between board independence and the permanence of non-GAAP exclusions reflecting opportunism rather than the economics of the firm, we find that the association declines following Regulation G and that managers appear to use exclusions to meet earnings targets prior to selling their shares more often in firms with fewer independent board members. Overall, our results suggest that board independence is positively associated with the quality of non-GAAP earnings.     

内部控制与异质机构持股的治理效应

本文实证检验了不同内部控制水平下,异质机构持股在抑制管理层盈余操纵方面的公司治理效应。研究发现,相比外地或短期机构持股,本地或长期机构持股更有助于提升应计质量和降低盈余噪音;当公司存在实质性内部控制缺陷时,本地或长期机构持股在抑制管理层盈余操纵方面的治理效应显著降低;相比国有控股,异质机构持股治理效应的发挥在非国有控股公司中受内部控制的影响更大;当公司存在财务报告实质性内控缺陷时,异质机构持股发挥的治理效应明显更弱。这些结果表明,异质机构持股治理效应的发挥离不开公司内部控制机制,二者之间是互补而非替代关系,这种互补关系主要由财务报告内部控制缺陷驱动。本研究有助于深化理解异质机构持股影响公司治理的具体作用机理,为实务界和监管机构改善公司治理、加强投资者保护提供经验参考。     

Making honest men of them: Institutional investors,financial reporting,and the appointment of female directors to all-male boards

In this paper, we theorize that dedicated institutional investors are more likely than transient institutional investors to appoint female directors to investee firms with all-male boards, particularly those with high opacity. We conjecture that dedicated investors appoint female directors as a governance mechanism to improve the financial reporting quality of these investee firms. Specifically, we find that through the appointment of female directors, dedicated institutional investors trigger the release of stockpiled negative accounting information, thereby increasing the likelihood of a stock price crash risk. We also show that dedicated investors, through the appointment of female directors, improve investee firms' corporate disclosure environment by decreasing earnings management. Finally, we find that through continued service on investee firms' boards, female directors reduce the future likelihood of a stock price crash.     

Institutional investors and earnings management associated with controlling shareholders' promises: Evidence from the split share structure reform in China

We examine the effectiveness of institutional investors in constraining aggressive earnings management induced by strong contractual incentives. To this end we focus on the consequences of earnings-related promises (covenants) negotiated between corporate controlling shareholders and minority shareholders during China’s split-share structure reform, wherein failure to achieve profit benchmarks had the potential to transfer significant wealth from controlling to minority shareholders. Our initial analysis provides evidence that profit-promised firm-years are, on average, associated with income-increasing earnings management, and that this association is stronger for: (i) firm-years in which the profit-promise was satisfied, and (ii) firm-years in which proxies for the level of unmanaged earnings suggest that earnings management was needed to satisfy the promise. However, such benchmark-beating behavior is weaker for firms with higher levels of institutional ownership. Further analysis documents that the exit threat of institutional shareholders can discipline earnings management associated with profit promises. We also show that the effect of institutional shareholders in reducing earnings management associated with profit promises is greater for domestic mutual funds and for privately controlled firms. Interestingly, our evidence suggests that institutional investors only play an effective monitoring role over earnings management when their incentives are strongly aligned with those of other minority owners. In other cases, our evidence suggests that these investors may exacerbate the level of earnings management.     

Board diversity and stock price crash risk

We show how board diversity influences stock price crash risk. By classifying board diversity into relation-oriented diversity (gender and age) and task-oriented diversity (tenure and education), we find that greater diversity on board can lower the risk of future stock crash. Additional analyses show that the effect of board diversity on future crash risk is stronger for firms with high information opacity and low institutional ownership. Overall, our findings provide new insights and suggest for more diverse boards to improve corporate governance practices.     

Female tainted directors,financial reporting quality and audit fees

This paper examines the association between the presence of female tainted directors on corporate boards and audit committees and (1) financial reporting quality and (2) audit fees. Female tainted directors are defined as female directors who have been directors of the firms that have previously been involved in financial failures and integrity indiscretions. Using real earnings management and audit fees as proxies for effective governance and board reputation, we find that firms with female tainted directors have higher real earnings management and higher audit fees. However, since prior literature has demonstrated that audit fees are higher for firms with female directors because female directors demand better auditing, we corroborate a supply-side effect of auditors charging higher audit fees when female tainted directors exist. We demonstrate this by showing that while there is an association between audit fee and real earnings management, this association is higher for firms with female tainted directors. Arguably, the governance and reputational benefits of female directors on boards are negated if such directors have tarnished professional reputations.     

Institutional investor distraction and earnings management

In this study, we explore the implications of institutional investor distraction for earnings management. Our identification approach relies on a firm-level measure of institutional investor distraction that exploits exogenous attention-grabbing shocks to unrelated parts of institutional investors' portfolios. We find that firms with distracted institutional shareholders engage more in both accrual-based and real earnings management. Further analyses show that the association between investor distraction and earnings management is stronger in firms with low analyst coverage and weak board monitoring, as well as in firms where managing earnings upward allows meeting or just beating their earnings target. Collectively, our results suggest that managers exploit the loosening in monitoring intensity resulting from investor distraction by engaging in earnings management. Even in the presence of institutional investors with superior monitoring abilities, limited attention may induce insufficient monitoring of earnings management practices.     

Informed trading before positive vs. negative earnings surprises

This paper investigates whether institutional investors trade profitably around the announcements of positive or negative earnings surprises. Using Korean data over the period of 2001–2010, we find that information asymmetry is larger before negative earnings surprises (earnings shock) among investors and that the trading volume decreases only before earnings shock announcements due to the severe information asymmetry. We also find that institutions sell their stocks prior to earnings shock announcements whereas individual and foreign investors do not anticipate bad news. Finally, we find that institutional trade imbalance is positively related to the post-announcement abnormal returns of negative events. This study complements and extends prior literature on informed trading around earnings announcements by documenting evidence that domestic institutions exploit their superior information around particularly earnings shock announcements.     

Foreign institutional investment horizon and earnings management: Evidence from around the world

This paper investigates whether and how the investment horizon relates to foreign institutional monitoring in constraining the self-interested managerial use of earnings management for a sample of firms from 29 countries. We find that equity ownership by long-term foreign institutional investors, irrespective of the strength of institutional controls in their home countries, is associated with lesser earnings management. Accounting for the significance of information asymmetry in earnings management and the ability of long-term foreign institutional investors to mitigate the information disadvantage associated with cross-border equity investments, we find that the constraining effect is stronger in firms with weaker information environments. Finally, using multiple proxies for the country- and firm-level agency, we find that monitoring by long-term, rather than short-term, foreign institutional investors is significantly effective in limiting earnings management in environments of severe agency conflicts. Overall, our findings draw attention to the heterogeneity in the monitoring role played by foreign institutional investors in influencing the financial reporting quality.     

ACCRUAL MANAGEMENT TO MEET EARNINGS TARGETS: UK EVIDENCE PRE- AND POST-CADBURY

Central to both the Cadbury Committee’s initial remit and its subsequent recommendations is the view that director integrity and board effectiveness play key roles in ensuring the quality and reliability of published financial statements. Using a constant sample, this paper tests whether the association between board composition and earnings management activity differs between the pre- and post-Cadbury periods. Earnings management is measured by the use of income-increasing abnormal accruals when unmanaged earnings undershoot target earnings. Results provide evidence of accrual management to meet earnings targets in both periods. However, while we find no evidence of an association between the degree of accrual management and the composition of the board of directors in the pre-Cadbury period, results for the post-Cadbury period indicate less income-increasing accrual management to avoid earnings losses or earnings declines when the proportion of non-executive directors is high. These results are consistent with the view that appropriately structured boards are discharging their financial reporting duties more effectively post-Cadbury.     

IFRS adoption in China and foreign institutional investments

We examine the effectiveness of China’s IFRS adoption from the perspective of an important set of financial report users, foreign institutional investors. We find that foreign institutional investment does not increase after China’s IFRS adoption, and some evidence that it actually declines, particularly among firms with weaker incentives to credibly implement IFRS, or with greater ability to manipulate IFRS’s fair value provisions. We also find that the association between earnings and returns generally declines after IFRS adoption, consistent with reduced earnings quality. In addition, we find that foreign institutional investors’ returns decrease after China’s IFRS adoption. Finally, the decline in foreign institutional investment is greater among investors from countries with weak institutions that have also adopted IFRS. Taken together, our evidence suggests that the weak institutional infrastructure in China’s transitional economy impairs IFRS’s intended goal of attracting institutional investment through improved financial reporting quality. Further, financial information users’ home country institutions and IFRS adoption experience affect the effectiveness of IFRS adoption.     

Do co-opted boards increase insider profitability?

Using a sample of U.S. firms over the period 1996–2014, this paper examines whether insider trading profitability increases with high board co-option. Indeed, we find that firms with a higher level of co-opted directors exhibit higher insider trading profitability, largely due to a lower level of managerial ability and analyst coverage. Co-opted boards are also unlikely to implement self-imposed insider trading restrictions, exacerbating this relationship. This positive association is mitigated by a higher level of external monitoring by institutional investors and if the CEO receives more performance-based incentives. Overall, co-opted directors demonstrate aligned interests with CEOs and corporate insiders rather than performing their role as monitors. As a result, a more co-opted board is positively associated with exploitative behaviour of insiders.     

The role of corporate board structure in attracting foreign investors

A long-recognized phenomenon in capital markets is the underinvestment in foreign equity securities, known as equity home bias. Our study examines the effect of board independence on the firm's ability to attract foreign equity capital. After accounting for potential endogeneity, we document that U.S. and non-U.S. foreign investors exhibit a strong preference for firms with more independent corporate boards. Further, our analysis indicates that the positive relation between board independence and foreign ownership is significantly stronger in countries with less developed legal institutions and poor external protection of investor rights. We suggest that it is in these countries that firm-determined characteristics such as independent boards can be most beneficial in attracting capital. We also find that institutional investors are more responsive to the impact of independent corporate boards than are other types of investors.     

Effects of takeover protection on earnings overstatements: evidence from restating firms

A staggered board can substantially protect a firm’s incumbents from takeover in either a hostile acquisition or a proxy contest. We use the existence of a staggered board as enhanced takeover protection and examine the association between staggered boards and earnings manipulation. Following a rigorous procedure to identify a sample of restating firms that overstated earnings, manually collecting data on several governance characteristics and using a matched-pairs methodology, we find that firms with staggered boards are less likely to overstate earnings. One potential interpretation of our results is that staggered boards lessen takeover threats and thus mitigate managers’ pressure to overstate earnings.     

Style investing and firm innovation

We document that transient, dedicated and quasi-indexed institutional investors exhibit a high degree of within-group heterogeneity with respect to their investment styles (i.e., growth, value, and balanced). We find that growth institutional investors enhance firm innovation in terms of R&D expenditures, R&D intensity, quantity and quality of patents and patent radicalness while value institutional investors impede innovation. Balanced investors have no significant association with innovation. Findings are consistent with style investing literature that growth and value styles are substitutes. Using investment styles, we present evidence that reconcile literature’s mixed findings on how transient and dedicated investors affect R&D and innovation, and why quasi-indexed investors, the largest group among all investors, have an insignificant effect. We also show that the effect of institutional investors depends on the firm’s relative level of innovativeness.     

Institutional investor horizon and stock price synchronicity: Do product market competition and analyst coverage matter?

This paper provides new insights into the relation between institutional investment horizon and stock price synchronicity and investigates whether this relationship depends on the intensity of product market competition and analyst coverage. Based on a sample of French listed companies, we find that long-term (short-term) institutional investors are associated with lower (higher) stock price synchronicity. The results also show that the negative effect of long-term institutional investors is more accentuated for firms in less competitive markets and with high analyst coverage. An additional analysis shows that the synchronicity reduction effect does not vary during the financial crisis. Overall, these findings suggest that unlike their short-term counterparts, long term investors reduce asymmetric information and help disseminate firm-specific information into stock prices.     

Information asymmetry,mutual funds and earnings management: Evidence from China

This paper investigates how information asymmetry and mutual fund ownership affect listed companies’ earnings management. We show that (1) reducing information asymmetry improves firms’ earnings management behavior; (2) relative to short-term mutual funds, long-term mutual funds promote earnings quality by adopting a monitoring role; and (3) by dividing firms into high/low information asymmetry groups, we find that the information environment significantly increases the effect of long-term mutual funds on firms’ earnings management. In this paper, we provide new evidence for the role that institutional investors play in a typical emerging capital market. Our results have clear policy implications: to increase earnings quality, it is essential to improve information transparency and develop long-term institutional investors.     

Effects of international institutional factors on earnings quality of banks

We examine the relation between legal, extra-legal and political institutional factors and earnings quality of banks across countries. We predict that earnings quality is higher in countries with legal, extra-legal and political systems that reduce the consumption of private control benefits by insiders and afford outside investors greater protection. Using a sample of banks from 35 countries during the pre-crisis period from 1993 to 2006, we find that all five measures of earnings quality studied are higher in countries with stronger legal, extra-legal and political institutional structures. We also find that banks in countries with stronger institutions are less likely to report losses, have lower loan loss provisions, and higher balance sheet strength during the 2007–2009 crisis period. Our findings highlight the implications of country level institutional factors for financial reporting quality and are relevant to bank regulators who are considering additional regulations on bank financial reporting.     

Do Women and Ethnic Minority Directors Influence Firm Value? Evidence from Post‐Apartheid South Africa

Previous studies on the value relevance of board gender and ethnic diversity have produced mixed results. This paper re‐examines this relationship using hand‐collected data of 245 South African listed firms over the period 2008–2013. We document a positive and significant effect of both board gender and ethnic diversity on firm value. We also find that the increase in firm value is greater when boards have three or more women directors. In contrast, ethnic minority directors contribute less to firm value when there are three or more on the board. Furthermore, we document that ethnicity has a concave relationship with firm value, but gender does not. We demonstrate that in better‐governed firms, ethnic diversity is more value relevant than gender diversity. Our results also suggest that financial crisis is associated with the propensity to restructure boards along gender and ethnicity. This paper sheds new light on the effect of board diversity in South African firms as the government increasingly pursues policies aimed at eradicating the effects of apartheid. Our results are robust after controlling for self‐selection and various forms of endogeneity.
