Bank Corporate Governance and Future Earnings Predictability

This study examines the impact of corporate governance on earnings predictability (future cash flows) for banks operating in 71 countries over the period 2007 to 2016. We find that board structure and CEO power have a significant influence on future cash flows. In contrast, risk governance variables have no significant influence. These findings vary between developed and emerging countries, common and civil law countries, and different sized banks. Board structure is more effective in predicting future cash flows in civil law and developed countries than in common law and emerging economies.


Introduction
An extensive literature examines how corporate governance and reporting quality impacts earnings but these issues have little been addressed in the banking area. The extant non-bank literature on earnings quality or earnings management typically link these to possible influences including: institutional ownership (Velury and Jenkins 2006); book-tax conformity (Atwood et al. 2010); gender diversity (Ye et al. 2010); board characteristics (Mashayekhi and Bazaz 2010); internal control regulation (Altamuro and Beatty 2010); employee expenses (Schiemann and Guenther 2013); the characteristics of chief financial officers (Dichev et al. 2013); and various country-level institutional factors (Kanagaretnam et al. 2014). Our study extends this literature by using bank governance indicators such as board structure, CEO The quality of accounting information derives from International Financial Reporting System (IFRS) standards and US Generally Accepted Accounting Principles (GAAP). Under the IFRS/GAAP framework, the current earnings of firms are reflected in their future operating cash flows (CFO t + 1 ). 3 Earnings predictability is an important measure as it deals with how well past earnings can explain current and future earnings and this can lead to more accurate valuations as it enables investors to better anticipate expected future cash flows (Velury and Jenkins 2006;Schiemann and Guenther 2013). Earnings predictability is a forward-looking measure of earnings quality as opposed to earnings management which is backward-looking. It provides a better understanding of expected future cash flows (CFO t + 1 ) derived from the company cash flow statement rather than the comprehensive income statement, which more likely determines future bank investment and lending activities (Hasan et al. 2012). Managerial discretion and manipulation are more pronounced in reporting earnings in the income statement (namely, through accrual-based accounting), than through changes in operational cash flows (using, cash-basis accounting measures). Despite the importance of earnings quality and predictability to banks, however, the extant literature is somewhat limited.
Prior banking literature documents that managers use discretion in financial reporting for several reasons, to: signal private information; manage risk; meet or beat earnings benchmarks; and to avoid adverse compensation and career consequences (Kanagaretnam et al. 2004(Kanagaretnam et al. , 2010Bushman and Williams 2012;Dechow et al. 2012;Dichev et al. 2013). Cornett et al. (2009) show that U.S banks use their discretion to smooth earnings during periods of low profitability by delaying the reporting of loan-losses and increasing the realization of securities gains. Under higher investor protection, banks may prefer forward-looking loan-loss provisioning and have a greater incentive to recognise larger provisions in order to smooth incomethis has a negative bearing on future earnings predictability. While the purpose of loan-loss provisions is to adjust banks' loan-loss reserves to reflect expected future losses, bank managers may also have incentives to use them to manage earnings and regulatory capital (Ahmed et al. 1999;Prior et al. 2014). As noted by Pérez et al. (2008) the accrual of loan-loss provisions is left to bank managers' discretion. However, the literature is somewhat inconclusive as to the link between loan-loss provisioning and earnings. Collins et al. (1995) find evidence of a positive link whereas Beatty et al. (1995) find no evidence of earnings smoothing.
Reforms to IFRS and U.S GAAP have not only made the standards more similar but have also aimed at improving earnings quality (see Dichev et al. 2013). Barth et al. (2008) contend that IFRS limits the opportunity of management to engage in opportunistic behaviour by restricting accounting options available to them. Leventis et al. (2011) also find that IFRS has been beneficial to users of financial reports as it has reduced opportunistic behaviour in earnings management. Although, the occurrence of earnings manipulation is hard to unravel (Dechow et al. 2010), a lack of correspondence between 'earnings' and 'cash flows' and deviations from industry and other peer experience can provide helpful indications of earnings management practice (Dichev et al. 2013). Altamuro and Beatty (2010) argue that internal control requirements can increase the validity of loan-loss provisioning and this aids (among other things) earnings persistence and cash flow predictability. Kanagaretnam et al. (2014) find an association between measures of earnings quality (as measured by earnings persistence and cash flow predictability) and strong country-wide legal, extra-legal and political institutions.
They also find that institutional factors can constrain opportunistic earnings management behaviour in banks.
The global financial crisis also raised questions about the link between corporate governance and bank earnings. For non-bank firms it has been shown that weak corporate governance structures result in poorer earnings quality (du Plessis et al. 2005;Hashim and Devi 2007;Jo and Kim 2007). Developments in corporate governance mechanisms and the introduction of IFRS/GAAP have generally improved earnings quality and reduced opportunistic behaviour (via tougher monitoring systems) (Dechow et al. 1996;Klein 2002;Xie et al. 2003;Cormier and Martinez 2006;Jo and Kim 2007;Shen and Chih 2007;Kent et al. 2010 andPrencipe andBar-Yosef 2011). Some of these monitoring mechanisms relate to strengthening inside corporate governance through legal and disclosure related legislation (macrolevel), and through improved systems and procedures at the firm-level (micro-level) (Agrawal and Chadha 2005;Hope and Thomas 2008;Altamuro andBeatty 2010, Holm andSchøler 2010;Kanagaretnam et al. 2014). In conjunction with compliance with IFRS/GAAP standards, various other governance mechanisms such as, board characteristics, CEO power and risk governance can also (if working properly) positively influence earnings quality by restraining managerial manipulations detrimental to firm value. This paper examines the impact of corporate governance on the predictability of future cash flows (CFO t + 1 ), (a forward-looking measure of earnings quality), using a sample of 306 large, medium and small commercial banks and bank holding companies (BHCs) chartered in 71 countries over the period 2007-2016. Our approach is (to some extent) in-line with Cornett et al. (2009), Altamuro and Beatty (2010) and Kanagaretnam et al. (2014), where we use the cash flow predictability measure as the main indicator of earnings quality. Cornett et al. (2009) study the relationship between earnings management and governance indicators for large U.S bank holding companies (BHCs). They use data from the 100 largest publicly traded BHCs from 1994 to 2002 and find that reported earnings, board independence, and capital are negatively related to earnings management. Altamuro and Beatty (2010) study the effect of internal control regulation on financial reporting. Based on U.S and international banks over 1986-1992 and 1995-2001 they document improvements in earnings' persistence and predictability of cash flows and find evidence of reduced earnings management activity in the form of benchmark-beating. They also find a decrease in accounting conservatism due to various internal control regulations. Overall, their main conclusion is that improvements in internal control monitoring and reporting lead to an enhanced quality of financial reporting in the banking industry. Kanagaretnam et al. (2014) study the impact of international institutional factors on earnings quality. Using a large sample of non-US banks from 35 countries over 1993-2006 they report that cash-flow predictability is higher in countries with stronger legal, extra-legal and political institutional structures. Both studies use loan-loss provisions to capture earnings management in the banking sector. While our study extends Cornett et al. (2009), Altamuro and Beatty (2010) and Kanagaretnam et al. (2014), we investigate earnings predictability of future cash flows (namely, CFO t + 1 ) and corporate governance relationships rather than focusing on loan-loss provisions-based earnings management and institutional factors directly. Moreover, unlike the aforementioned studies, we rely on future cash flows from the company cash flow statement rather than future earnings or comprehensive performance from the income statement, primarily because managerial discretion is greater in measuring earnings compared to operational cash flows. Given the phenomenon of managerial discretion and accrual-based earnings, we also argue that current earnings are likely to be a better predictor of future cash flows compared to current cash flows, consistent with Greenberg et al. (1986) and Dechow et al. (1998). As for our key empirical findings, we find that board structure and CEO power have a significant influence on the earnings predictability of banks. The results vary for emerging and developed countries, and common and civil law countries as well as different bank sizes.
Our study contributes to existing research in several ways. First, to the best of our knowledge, this is the first study to use an extensive international sample of banks across a large number of countries (71) countries (over 2007-2016) which enables us to investigate the link between corporate governance and earnings predictability in not only developed and emerging economies but also across economies with varying legal and other institutional features. We show a positive and significant relationship between current earnings and CFO t + 1 , indicating that current year's reported earnings are an important predictor of future earnings. Small boards with more independent directors also help predict future cash flow (CFO t + 1 ) whereas CEO duality (where the CEO also acts as the Chairperson) is more likely to have a negative effect on future earnings predictability. We further report that having a risk committee member on the board is positively associated with CFO t + 1 . These findings are consistent with both Velury and Jenkins (2006) and Atwood et al. (2010) who show that future cash flows are positively linked to current earnings.
Second, in-line with Pathan (2009), Pathan and Faff (2013) and Mollah and Zaman (2015) we argue that bank governance factors are effective in enhancing earnings quality and reducing risks. Cornett et al. (2009) suggest that corporate governance plays some role in earnings and earnings management at large U.S. banks as they find a significant negative relationship between earnings management and board independence. Our focus on the link between corporate governance indicators and CFO t + 1 is motivated by the conceptual framework of IFRS/GAAP, which suggests that users and investors should obtain quality information from financial reports to assess CFO t + 1 . We find (as expected) a significant influence of board structure and CEO power on earnings predictability of our sample banks (but we do not find any strong relationship with risk governance variables). Our study, therefore, provides empirical evidence consistent with the signalling theory built on financial reporting under the IFRS/GAAP regime as well as agency theory predictions from the regulatory environment concerning board structure and CEO-power in explaining earnings predictability.
Third, banks are highly regulated, compared to non-banks, and need to not only comply with accounting standards and listing requirements on disclosure, but also on a wide range of other regulatory requirements (Basel requirements, domestic supervisory regulations and so on). Among explanations as to why banks exposed themselves to excessive risks during the run-up to the global financial crisis was that there was a failure of risk management (Ellus and Yerramilli 2013). This motivates us to investigate whether predicted earnings of banks are influenced by bank risk governance features. We find little evidence that bank risk governance features impact earnings predictability.
Finally, while existing studies mainly use samples of large banks, we focus on a broader range of bank sizes across a larger number of (71) countries. This enables us to investigate earnings predictability from a wider range of perspectives, namely: across different legal regimes (civil vs. common law countries); stages of economic development (developed vs. emerging economies); and for varying bank sizes (large to small). Kanagaretnam et al. (2014) find that banks' cash-flow predictability is higher in countries with stronger legal, extra-legal and political institutional structures. Overall, our results vary between developed and emerging countries, common and civil law countries, and large, medium and small sized banks. Board structure is more effective in predicting future cash flows in civil law and developed countries than in common law and emerging economies. CEO power reduces future earnings predictability in common law and emerging countries while less so in civil law economies (and to some extent increasing predictability in developed countries). Risk governance also indicates variations in influence between civil and common law countries as well as across developed and emerging economies. In general there is greater similarity in the influence of risk governance in common law and emerging countries although overall they do not appear to have a significant influence. Again, governance variables also have a differential influence on earnings predication for banks of varying size.
The remainder of the paper is structured as follows: Section 2 provides an overview of literature and hypotheses on board structure, CEO power and risk governance while Section 3 discusses the methods, data and model specifications; Section 4 focuses on the empirical results and robustness tests and finally Section 5 provides the concluding remarks.

Related literature and hypotheses development
A number of studies measure earnings quality by assessing the ability of earnings to predict future cash flows (Doyle et al., 2003;Cohen et al., 2004;Francis et al., 2004;Van der Meulen et al., 2007;Melumad and Nissim, 2009;Atwood et al. 2010Atwood et al. , 2011. Researchers use different proxies for earnings quality such as: earnings management; accrual quality; earnings predictability; smoothness; persistence; earnings informativeness; and benchmark beating (Francis et al. 2004;Dichev et al. 2013). Another indicator of quality relates to earnings with a high predictive value, namely, a strong association with future cash flows. Lipe (1990) considers earnings predictability as the ability of earnings to explain itself. If past earnings are good estimates of current earnings, then predictability is said to be high. The quality of firms' earnings relates to the usefulness of accounting information to financial statement users. While quality of earnings is a concept having multidimensional constructs, the foundation of earnings quality derives from the 'conceptual framework' of accounting standards, namely the IFRS/ GAAP regime. IFRS/GAAP promote quality disclosure and reporting and as a consequence financial reports are designed to provide value relevant information. In the IFRS/GAAP framework, both relevance and reliability are viewed as the two principal qualitative characteristics of earnings numbers. To be relevant, among other things, earnings numbers must have predictive value. The predictive nature of accounting earnings is also manifest in valuing firm's equity which also requires investors to anticipate expected future cash flows (Velury and Jenkins 2006). Dechow (1994) contends that current earnings generally produce better predictions of future cash flows. Current earnings figures are believed to be of higher quality the more they can predict future cash flows, and the quality of current accounting information is firmly rooted in strict compliance to IFRS/GAAP based accounting standards.
Furthermore, firms with higher earnings quality are more likely to have good governance systems that signal the reliability of their financial reporting processes (Engel 2005). The direct and indirect agency costs relating to managerial incentives can be mitigated through several mechanisms. It is argued that good governance assists in aligning managers' interests with those of shareholders via reduced agency costs. Similarly, CEO power has also been found to be linked to the quality of firm financial statements (Zhang and Wiersema 2009). Agency theory predicts that powerful CEOs tend to be entrenched and operate detrimentally (to shareholders) by extracting private benefits of control, including, empire building (Jensen 1986). Good governance therefore recommends the separation of the role of CEO and Chairperson as well as promoting a larger number of independent board members (Shleifer and Vishny 1997). In the same vein (and since the global financial crisis) it has been suggested that risk management mechanisms be emphasised more in the governance of banks and other financial firms (Mongiardino and Plath 2010;Sabato 2010;Aebi et al. 2012). In particular, the aforementioned studies emphasize greater risk-reporting to the board (rather than the CEO), and to check the power of CEOs thus reducing possibilities for opportunistic behaviour. The following incorporates these issues in our methodology on bank earnings predictability as outlined below.

Board structure and earnings predictability
Agency theory suggests that board independence acts as a watchdog over a firm's operations and provides monitoring incentives for reducing agency costs. The existence of independent directors on the board therefore is expected to enhance earnings ability to predict future cash flows. Chen and Jaggi (2000) provide evidence that board independence is crucial in influencing the level of superior financial reporting. Cheng and Courtney (2006) document a significant positive association between the proportion of independent directors and the extent of reporting quality.
Again, board size is also one of the factors influencing the effectiveness of board oversight duties. There has been continued debate on the role of board size, although agency theory suggests that larger boards support more effective monitoring (Coles et al. 2008;Pathan 2009). Small boards are favoured for: being easier to co-ordinate; quicker in making decisions; less likely to have free-rider problems; and more likely to be innovative (Dimitropoulos and Asteriou 2010;Mollah and Zaman 2015;Pathan 2009). Xie et al. (2003, p. 300) point out that BA smaller board may be less encumbered with bureaucratic problems and may be more functional. Smaller boards may provide better financial reporting oversight^. Vafeas (2000) and Cho and Rui (2009) find that earnings numbers of firms with small boards are more informative. However, there are opposing views about large boards and their role in monitoring. Empirical studies conclude that a greater number of board members will likely lead to more independent directors and provide more expertise, experience, knowledge and diversity and increase the board's monitoring capacity (Dalton et al. 1998;John and Senbet 1998;Dalton et al. 1999;Linck et al. 2008). Rahman and Ali (2006), however, point out that large boards can be less effective in reducing earnings manipulation.
Given the mixed evidence on board independence, size and earnings quality, we hypothesize that board structure, 4 especially a strong board structure (smaller board size and greater independence) helps improve the earnings predictability of banks: H1: Board structure has an effect on earnings predictability. Or -Small and independent boards have a positive effect on earnings predictability.

CEO power and earnings predictability
The governance literature defines CEO power in a variety of ways: CEO duality; internallyhired CEO; and CEO tenure (May 1995;Hermalin and Weisbach 1998;Morck et al. 1989;Adams et al. 2005;Pathan 2009;Fracassi and Tate 2012;Mollah and Zaman 2015). A CEO becomes more powerful when they also chair the board (CEO-duality) and such power grows with employment tenure and if the CEO is internally-hired (Pathan 2009;Fracassi and Tate 2012;Mollah and Zaman 2015). CEO power can be entrenched thereby restricting information flows to other board directors, impacting board decisions and undermining the board's independence to oversee managers. Pathan (2009) documents that CEO power is negatively related to bank risk-taking, namely, bank CEOs have incentives to take less risk to secure their jobs and human capital investment by accepting some safe value-reducing projects, and rejecting risky but value-increasing projects (May 1995;Saunders and Cornett 2006). Similarly, in the earnings informativeness literature, CEO duality seems to have a detrimental effect on the usefulness of earnings numbers (Gul and Lai 2002;Anderson et al. 2003;Firth et al. 2007). Combining two roles (chairperson and CEO) along with longer tenure exacerbates the potential for managing earnings, thus impairing the quality of reported earnings (Saleh et al. 2005;Prencipe and Bar-Yosef 2011). Similarly, other CEO characteristics, such as whether the CEO was an internal appointment and the length of tenure can also have a negative bearing on financial statement quality and therefore earnings predictability (Pathan 2009;Fracassi and Tate 2012). Following the aforementioned agency theory views we propose a second hypothesis: H2: CEO power has a negative effect on earnings predictability. Or-CEO-duality, CEO-internal and CEO tenure have negative effects on earnings predictability.

Risk governance and earnings predictability
In recent years, risk management has become an integral part of governance in the banking sector. Mongiardino and Plath (2010) outline best practice in banking risk governance and highlight the need to have at least a dedicated board-level risk committee, of which a majority of members should be independent, and also that the Chief Risk Officer (CRO) should be part of the bank's board (Aebi et al. 2012). Both Aebi et al. (2012) and Ellus and Yerramilli (2013) note that risk governance (having a CRO on the board as well as a Risk Management Committee) matters for bank risk-taking as they perform risk monitoring functions. As banks are at the center of undertaking risky business, the main purpose of the risk management function is to mitigate the risk of large losses, known as tail risk (Ellus and Yerramilli 2013). Ellus and Yerramilli (2013) suggest that a strong and independent risk management function in banks can curtail such tail risk exposures. Kashyap et al. (2008) and Stulz (2008) also contend that the presence of a strong and independent risk management team is necessary to control tail risk exposures of financial institutions.
Policy makers around the globe have emphasized the importance of appropriate risk management practices being applied in financial institutions, including the existence of a risk management committee and appointment of a CRO (Brancato et al. 2006;Sabato 2010). Therefore, risk governance mechanisms, together with clear CRO reporting lines are important components of bank corporate governance. A strong risk management function is necessary to correctly identify risks and prevent excessive risk-taking (Kashyap et al. 2008;Stulz 2008) that cannot be controlled entirely by regulatory supervision or external market discipline (Ellus and Yerramilli 2013). Similarly, the role of the CRO and other risk managers is also important to evaluate the viability of bank's loans and other investments. Risk managers or CROs can limit a bank's propensity for excessive risk-taking.
Again, female directors are Bmore risk-averse to fraud and opportunistic earnings management^ (Man and Wong 2013, p. 391) than their male counterparts. In suggesting that women are generally more conservative and less inclined to take excessive risks in banks (Palvia et al. 2014), Sunden and Surette (1998) also reveal that female directors are more riskaverse in making decisions. Srinidhi et al. (2011) demonstrate that the participation of woman directors on boards increases the quality of reported earnings. But, Sun et al. (2010) find no relationship between female directors and earnings management and Berger et al. (2014) indicate that a higher proportion of female board members increases bank portfolio risks. Despite diverse results on the link between risk governance and earnings predictability, we propose the following hypothesis: H3: Risk governance has a positive effect on earnings predictability Or the presence of a -Risk committee, chief risk officer and female directors have a positive effect on earnings predictability.

Data
We primarily focus on a sample of (all) listed commercial banks and BHCs with accounting data available in Bankscope and market data available in Datastream over 2007-2016. We retain only institutions with an independent ownership structure defined by the database (nonindependent banks such as subsidiaries can be influenced by the parent). The remaining banks should have at least four years of accounting, market and governance data. The selection criterion leads to a sample of 306 banks from 71 countries. We present the sample distribution in terms of country and year in Table 1. Panel A shows the country distribution, which indicates a high proportion of banks in Japan and the U.S. For example, we have 61 banks from Japan and 27 from the US in the sample.

Methodology
First we apply OLS estimation to our baseline models and then two-step system GMM for robustness checks. System GMM can effectively address endogeneity/causality concerns between the variables used (Arellano and Bond 1991;Blundell and Bond 1998;Arellano and Honoré 2001).

Model specification
We use the following model to test our hypotheses in-line with Cornett et al. (2009), Altamuro and Beatty (2010), Kanagaretnam et al. (2014) and others in the literature: Where, CFO i,(t + 1) is the cash flow from operations at time t + 1 (CFO i,(t + 1) is the proxy used to test for earnings predictability). ROIAA i,t is the current profitability (return on operating income by average assets), CG ,it is a matrix of firm level corporate governance variables of bank i at time t, ROIAA i,t * CG i,t is the interaction term, X i,t is a matrix of firm-level control variables of bank i at time t, ME it is a matrix of country level macroeconomic variables at time t, ε i,t is the error term, α 0 is the constant, and α, β, γ and δ are the vectors of coefficient estimates. All hypotheses are linked to the CG matrix, which includes board structure (board size, board independence), CEO power (CEO-duality, CEO-internal and CEO tenure) and risk governance (risk committee, chief risk officer and female directors) variables. In addition, IFRS, Big-4 audit firms, 1/Z-score (risk-taking), Tier-1 capital, deposit insurance, log total assets and GDP are used as control variables. The descriptions of these variables are shown in Table 2.
4 Empirical results

Descriptive statistics and correlation matrix
The summary statistics for earnings predictability, corporate and risk governance, and firm and country-level control variables are shown in Table 2. The panel data comprising observations for each bank span the 2007 to 2016 period and include 306 publicly-listed banks. The mean (median) of CFO t + 1 as the proxy for earnings predictability is 0.022 (0.019) indicating that average earnings predictability is positive. The mean (median) of current earnings is also 0.022 (0.019). Similarly, the average value of an alternative proxy for earnings predictability -the standard deviation of the residuals (ѵ j ) from equation Earn j , t = ϕ 0 , j + ϕ 1 , j Earn j , t -1 + ѵ j , t deflated by firm j's total assets (RESTDEV_ROIAA) -is 0.014 (0.010), which is also positive. Regarding the corporate governance variables, we find that mean board size is 12 and on average, independent directors constitute around 51% of board members. Again, about 24% of CEOs also have the co-role as Chairperson and almost 78% of them are internally promoted with an average tenure of 5 years. Turning to the risk governance variables, nearly 82% of the sample banks have risk committees and 49% have a CRO. The percentage of female directors is relatively low, approximately 10%. For control variables, we find 54% of banks report their accounts under IFRS and 85% are audited by the Big-4 audit firms.
The mean inverse Z-score (1/Z represents an insolvency risk measure), Tier 1 capital and deposit insurance variable for the sample are, respectively, 0.618, 0.093 and 0.404. Finally, log total asset and log GDP size have mean values, respectively of, 17.061 and 27.315. The correlation matrix shows that current earnings, corporate governance, and risk governance variables typically have a positive relationship with CFO t + 1 , (with the exceptions of our board independence and risk committee measures which suggest a negative link). 5 Among the control variables, IFRS and total assets also have a negative link to CFO t + 1 , and Big4 a positive relationship. The correlation matrix indicates no sign of serious multi-collinearity among the explanatory variables. 6   Table 3 reports the results of regressions 1-3. Model 1 represents a base estimation of current earnings (ROIAA) and its interaction with corporate governance variables separately for board structure, CEO power and the risk governance variables. Models 2-3 include a couple of controls, such as whether the bank is a BHC or not and a dummy for the 2008-2009 financial crisis, respectively. All three models in Table 3 reveal a positive and significant relationship between current earnings and CFO t + 1 (at the 10% level), indicating that the current year's reported earnings are an important predictor of future cash flow. These results confirm that quality earnings in the IFRS/GAAP framework have significant predictive power in determining bank CFO t + 1 . The finding is also consistent with Velury and Jenkins (2006) who show a positive and significant relationship between earnings and cash flows, as well as Atwood et al. (2010) who find that future cash flows are positively linked to current earnings.
Model 1 presents the effects of the interaction terms of current earnings and governance variables (namely, board size and independence; CEO-duality; CEO-internal and CEOtenure; risk committee; chief risk officer; and female director) on CFO t + 1 . The results of the interaction variables are largely consistent with our main hypotheses suggesting a 'complementary' link between earnings and governance in explaining CFO t + 1 . Firstly, on board structure variables (board size and independence), we find a significant negative relationship between CFO t + 1 and the interactive variable of accounting earnings and board size (ROIAA*LNBOARD) (10% level) illustrating that a small bank board is capable of predicting future cash flows. Conversely, the interactive variable of accounting earnings and independent boards (ROIAA*INDEPENDENT) has a positive significant impact on CFO t + 1 (5% level). So it appears that a small board with more independent directors helps predict future bank cash flows. The findings remain unchanged in all the models (Models 2-3), hence, our H 1 is fully supported. The results are also consistent with those of Al-Dhamari and Ismail (2013) (although they contrast with those from Mashayekhi and Bazaz 2010).
Secondly, with respect to CEO power (CEO-duality, CEO-internal and CEO-tenure), we find (as expected) a negative relation between CFO t + 1 and the interactive variable of earnings and CEO-duality (5% level). So CEO-duality reduces earnings quality / predictability. The variable that interacts earnings with CEO-internal and CEO-tenure shows a positive but insignificant relation with CFO t + 1 . These findings partially support our H 2 , and it seems that bank CEOs are more aligned to pursuing their own rather than the firms' interests.  Table 2. Standard errors in parentheses. *** p < 0.01, ** p < 0.05, * p < 0.1 Finally, with regard to the risk governance variables (risk committee, chief risk officer and female director), we report mixed results for the effects of the variable that interacts earnings with the risk indicators and bank CFO t + 1 . Consistent with expectations, we report that the risk committee interaction variable is positively associated with CFO t + 1 (1% level), illustrating that it is capable of helping to improve earnings quality and hence predict future cash flow. However, the chief risk officer interaction variable reveals a significantly negative effect on CFO t + 1 , (contrary to expectations), while the female director interaction variable has no significant relationship. These mixed findings lead us to marginally support our H 3 .
Again, both Model 2 and Model 3 extend the analysis of Model 1 with other control variables, respectively, for the effect of being a bank holding company (BHC) and during the period of the global financial crisis (2008)(2009). In both models we observe that the results reflect those from Model 1 (for all interactive corporate governance and earnings variables) in terms of explaining CFO t + 1 . In addition, Model 2, which includes the volatility in current earnings (std_roiaa) as an additional variable, also documents a positive significant effect of bank holding company status and future earnings, while there is a positive but insignificant effect of earnings volatility on CFO t + 1 . Further tests also indicate no significant effects on future earnings, 7 so volatility in current earnings is not an issue in determining future earnings. Furthermore, Model 3 also shows that there was no significant effect of the global financial crisis in terms of being able to predict future bank earnings over the sample period.
With regard to the control variables in Models 1-3, we observe consistent findings for the IFRS dummy and Tier 1 capital variable indicating a positive influence on CFO t + 1 . The IFRS dummy has a positive link to CFO t + 1 , which is consistent with expectations. The results also illustrate that capital adequacy, as a regulatory requirement and an indicator of bank solvency, is a predictor of future earnings. On the other hand, deposit insurance, bank size (total assets) and GDP variables show a negative relation with CFO t + 1 . Even though deposit insurance is a safeguard to protect deposit holders, it lowers the ability to predict future CFO (CFO t + 1 ) perhaps reflecting the confounding effect of moral hazard on bank's future earnings. Similarly, smaller bank size and country GDP increases the predictive power of future earningspossibly because banking business is less complex in these countries. Finally, bank risk (z score) does not explain future bank earnings across any of our estimates, while there is a positive significant relation between audit quality (Big-4 audit firms) and CFO t + 1 found in Model 1 only.

To check the validity of our earlier results (Table 3), we construct three corporate governance indices and conduct the regression analysis between the indices, their interactions with accounting earnings and earnings predictability (CFO t + 1 ). We construct strong board, CEO power and strong risk governance based on corporate governance variables. 8 Table 4 Models 1-3 show the relationship between the interacted governance and other control variables, respectively, with CFO t + 1 . 7 The results are not reported due to space, but are available on request. 8 'Strong board' is defined as having a board size (number of members) lower than the median and a greater than median number of independent directors. CEO power is defined as having an internally appointed CEO that plays a dual role and who has board tenure higher than median. Similarly, strong risk governance is defined as having both a risk committee and risk officer as well as having a greater than median number of female board members. Table 4 reveals a strong positive and significant relationship between current earnings and CFO t + 1 at the 1% level across the three models thus reinforcing that the current year's reported earnings is an important predictor of future cash flow. In Model 1 of Table 4, the strong board index interactive variable shows a negative effect on CFO t + 1 (10% level). This moderately supports our findings in Table 3 and H 1 , implying that current earnings and strong boards have sufficient explanatory power to determine future earnings. With regard to our CEO power index interactive variable we also find a strong negative and significant relation with CFO t + 1 at the 1% level (in contrast to Table 3 findings). Therefore, H 2 is fully supported, namely that powerful bank CEOs tend to pursue their own interests over firms' interest and this is reflected in less predictable (poorer quality) future earnings. As for strong risk governance we find a  Table 2. Standard errors in parentheses. *** p < 0.01, ** p < 0.05, * p < 0.1  Table 4 as in Table 3.

Corporate governance and earnings predictability in different legal jurisdictions (common law versus civil law countries)
Following Table 4 Models 1-3, we re-estimate similar models after splitting the sample into banks based in common or civil law countries. The results are reported in Tables 5 Models 1-3 of Panels A and Panel B. In Panel A estimates for the civil law countries are reported and here we see that the interactions variables with current earnings reveal findings as reported in Table 4 for board structure variables but not for CEO power and risk governance variables. In Panel B of Table 5 the findings for banks operating in common law countries shows that CEO power and risk governance variables (but not board structure) improve cash flow prediction. In sum, the findings for common law countries generally confirm our earlier findings reported in Table 3. Clearly there are legal differences across countries that influence the effectiveness of governance mechanisms in enhancing bank earnings quality.

Corporate governance and earnings predictability for banks operating in developed and emerging countries, and for institutions of varying size
In Table 6 (Models 1-3 of Panels A and B), we re-estimate the same regression after splitting the sample based on countries' state of economic development (developed vs. emerging) from the IMF definition. Panel A reports the results for banks operating in developed countries where the board structure interaction variables with current earnings (rather than CEO power and risk governance structure interaction indicators with current earnings) are found to have a significant influence on future cash flows. We find that both CEO-duality and female directors have a positive link to CFO t + 1 , suggesting that bank CEOs and female directors are more likely to provide positive signals to the market to maintain sustained earnings for banks. In   Table 3 for CEO power and risk governance interaction variables with current earnings, while not for board structure interaction variables. Clearly stages of economic development impact bank earnings quality.
We also re-estimate the same regression after splitting the sample according to bank asset size. 9 The findings are somewhat mixed for large and medium-sized banks, although for smaller banks we do find stronger evidence that board structure and CEO power interaction variables help predict future bank earnings.

Robustness checks
To check the robustness of our findings, we estimate our baseline regressions using an alternative earnings predictability measure following Francis et al. (2004). This proxy is the standard deviation of the residuals (ѵ j ) defined from equation Earn j,t = ϕ 0,j + ϕ 1,j Earn j,t-1 + ѵ j,t deflated by firm j's total assets, where Earn j,t = firms j's net income before extraordinary items in year t, larger standard deviation of the residuals (ѵ j ) reflects lower earnings predictability. Our findings 10 show a positive and significant relationship between current earnings and CFO t + 1 at the 10% level, consistent with the baseline findings in Table 3. Overall, board size has a negative relation, independent boards and interactive variable of earnings and independent boards a positive influence on future earnings predictability and supporting H 1. Other findings also show that CEO power and interactive variables with earnings do not help predict future earnings (supporting H 2 .) and we do not find any support for an influence of risk governance factors and their interactive variables with earnings (no support for H 3 ).
Finally, we re-estimate eq. 1 using the two-step system GMM approach 11 adopted by Arellano and Bover (1995) and Blundell and Bond (1998) to help deal with potential endogeneity/causality issues. Overall the main findings are in accordance with those reported in Table 3, namely, that board structure, CEO power and their interactive variables with earnings have a significant influence on the earnings predictability of banks, but this is not the case for the risk governance measures and their interactive variables with earnings.

Conclusion
We examine the impact of corporate governance on earnings predictability in all listed banks from 71 countries over the period of 2007-2016 in the light of IFRS/GAAP. High quality accounting numbers are important to banks (as well as other firms) because without accurate accounting information they are unable to precisely estimate their future earnings prospects and valuations. Under IFRS/GAAP frameworks we posit that higher quality reported bank earnings should be a better predictor of future earnings. Corporate governance mechanisms can also mitigate agency problems and enhance bank performance. Since operating earnings are a key contributor to bank performance, governance mechanisms should be in place to promote disclosure quality and ensure sustained earnings. Effective governance provides positive signals to the market regarding the capacity of the firm to generate sufficient earnings over time. Good governance should lead to quality disclosure and earnings and improved financial reporting that ultimately protect investors' interests and restrain managerial opportunism.
In particular, we evaluate whether current earnings, board structure and CEO power as well as the risk governance features of banks can effectively predict future cash flows (CFO t + 1 ). Our results consistently suggest that CFO t + 1 is positively associated with current earnings. Interactive governance variables relating to board structure and current earnings generally show high explanatory power in influencing future CFO, as expected. However, such explanatory power tends to lessen in common law and emerging countries. Again, we find interactive CEO power variables reduce the predictability of future bank cash flows (CFO t + 1 ). However, the negative effects of CEO power variables are more noticeable in common law and emerging countries. We also find that risk governance variables have little impact on earnings predictability. Further differences are observed for the influence of governance variables on different sized banks. Overall, these results suggest that the IFRS/GAAP disclosure regime and powerful board structure can contribute to determine future bank cash flows. These findings are robust to different sub-samples covering country legal status (common law/civil law), stages of economic development (developed/emerging) and different bank sizes.
Our results imply the importance of the accounting regime -IFRS/GAAPand more specifically quality earnings as instrumental in reflecting future bank cash flows. The effects of standard governance interactive measures on earnings predictability, in particular small and independent boards enhance earnings predictability while CEO power tends to lessen predictability. Risk governance interactive features appear to have at best a marginal influence. The study highlights how board structure and risk governance features can influence earnings quality and highlights differences that occur depending on whether banks operate in various legal regimes (civil versus common law), and varying stages of economic development (developed versus. emerging) and for different bank sizes. Policymakers should perhaps consider strengthening the risk governance features of banks as these appear to have a limited influence on bank earnings quality.
