Corporate governance among banks listed in the Philippine Stock Exchange.


Kabigting, Leila C.


INTRODUCTION

Asian central banks initiated corporate governance reforms among banks as an aftermath of the 1997 Asian Financial crisis. By 2008, when the global financial crisis set in, corporate governance reforms already in place among Philippine banks provided safety nets which minimized falling asset prices and losses.

Since 2002, listed companies in the Philippines have been required to discuss their adoption of best practices in Corporate Governance in their annual reports on SEC Form 17-A submitted to the Securities and Exchange Commission (SEC).

This paper evaluates corporate governance among banks listed in the Philippine Stock Exchange (PSE) from the period 2005-2009. Our main goal is to investigate the determinants of corporate governance and the dynamics of their relationship to corporate governance. Thus, we will test the following hypotheses:

HYPOTHESES

HI: Corporate governance (as proxied by insider ownership) has a significant relationship with an independent board of directors, bank size, return on assets (ROA), return on equity(ROE), earnings per share (EPS), age, and non performing loans ratio (NPL).

H2: Corporate governance (as proxied by board size) has a significant relationship with an independent board of directors, bank size, return on assets (ROA), return on equity(ROE), earnings per share (EPS), age, and non performing loans ratio (NPL).

LITERATURE REVIEW

Jensen and Meckling (1976) agency theory discussed that agents or managers perform functions on behalf of shareholders. However, these agents or managers will prioritize maximizing his wealth ahead of the shareholders' value since his compensation is tied to managerial performance. Thus, Jensen and Meckling (1976) discussed that internal and external monitoring costs are incurred to minimize conflict of interest. As Elsayed (2007) cited Johnson et al. (1996), the board of directors' main functions are: "monitoring management actions, advising the CEO and getting external resources that are vital to build corporate capabilities (p. 1204)."

Elsayed (2007) defined the total number of directors on the board as the measure of board size. El Mehdi (2007) showed that board size is positively related to corporate governance which means a larger board would have more directors to monitor agency problems, review management actions, bring greater opportunities. The presence of independent directors in the board enhance board governance, reduce financial statement fraud, increase transparency and disclosure, and protect minority shareholders. (Leung and Horwitz, 2004). However, El Mehdi cited Jensen (1993) that there is an upper limit to boards, which is eight directors, as more than this will affect group dynamics and board performance. On the other hand, El Mehdi (2007) and Barucci and Felini (2005) cited that there is a large literature establishing a negative relationship between board size and firm performance; see Hermalin and Weisbach (2001), Yermack (1996) and Barucci and Ceccacci (2005).

Corporate governance literature uses two alternative approaches to measuring corporate performance. The first uses accounting measures of corporate performance. These include return on assets, return on equity and earnings per share. Elsayed (2007) presented that return on assets is net profit divided by total assets, which reflects operating results rather than capital structure decisions. The relationship between earnings and managerial shareholdings can be positive (Korczak and Korczak, 2009) or negative (Korczak and Korczak, 2009; Kuznetsov, Kapelyushnikov, Dyomina (2008) at higher levels of managerial shareholdings.

Barucci and Felini (2005) studied the determinants for corporate governance in listed firms in the Italian stock exchange. These included balance sheet data, ownership structure, company performance and qualitative features. They concluded that companies with a large shareholder and/or large minority blockholders have poor governance and protection of shareholders. However, Korczak and Korczak (2009) presented that concentrated holdings of several investors rather than a single large shareholder will result into the blockholders protecting themselves thus making sure that managers and investors' interests are aligned.

Barniv and Bao (2009), Elsayed (2007) discussed the other approach to measuring corporate performance applies market valuation measures, especially the Tobin's q ratio which takes into account risk, return and present value of future profits. Elsayed (2007) presented Tobin's q ratio as:

Tobin's q ratio = [Market Value + Book value of Preference Capital + Book value of Long term Debt + Book value of Inventory + Book value of Current Liabilities - Book value of Current Assets] / [Total Assets] (see Lee and Tompkins, 1999).

Barniv and Bao (2009) defined EPS as earnings per share in their earnings-return regression. Their findings showed that valuation models perform better for companies with a greater analyst following, smaller forecast errors, relatively high public ownership and a strong board structure.

Korczak and Korczak (2009), Kuznetsov, Kapelyushnikov, Dyomina (2008) and Elsayed (2007) introduced control variables such as board size, institutional ownership and management shareholding, firm size, age in the estimated models affecting performance and ownership, so that there will be no specification errors. Size is the logarithm of the firm's total assets. (El Medhi, 2007). Kuznetsov, Kapelyushnikov, Dyomina (2008) defined age as the number of years since the firm was founded. Their results showed that in terms of the control variables, the regression coefficients for the size are positive and significant while the firm's age has proven to be insignificant.

EMPIRICAL ANALYSIS

The study included the following listed banks in the Philippine Stock Exchange: Banco de Oro (BDO), Bank of the Philippine Islands (BPI), China Banking Corporation (CHIB), Metropolitan Bank and Trust Corporation (MBT), Philippine National Bank (PNB), Philippine Bank of Communication (PBC), Rizal Commercial Banking Corporation (RCB), Security Bank (SECB), Union Bank of the Philippines (UBP) from 2005-2009. Most of the banks are traded daily. Also, the following banks: BDO, MBT, BPI, PNB, RCB, UBP, CHIB, belong to the top 10 banks that already comprise 70%-75% of the total assets of the commercial banking industry. Data was taken from the annual reports and 17-A from years 2005-2009 and from the data set from years 2005-2008 provided by Lagmay, Chong and Lee (2010).

The study used panel data estimations with fixed effects to help control for unobserved heterogeneity. We used the fixed effects since we are not using variances per se but the actual values themselves. Also, stationarity is assumed here. (Lagmay, Chong, Lee, 2010).

The dependent variable in the first model is corporate governance (proxied by insider ownership (io) and the independent variables: independent directors, bank size, age, roe, roa, npl, eps.

The second model has corporate governance (proxied by board size) as the dependent variable and the independent variables are: independent directors, bank size, age, roe, roa, npl, eps.

The first model (Table 2) resulted to the non-significant variables: bank age, independent directors, non performing loans (npl) and return on equity (roe). Bank age is defined as when the bank was founded. The result shows that insider ownership has nothing to do with bank age. This is consistent with Kuznetsov, Kapelyushnikov, Dyomina (2008) study that found bank age to be an insignificant variable in corporate governance. Although, Leung and Horwitz (2004) showed that independent directors have a positive relationship to corporate governance, our results show that it is insignificant and negative relationship. This could be that there are at least two independent board of directors in the bank who may only give advice/suggestions but banks usually have concentrated family ownership. The non performing loan (NPL) is insignificant because this is a result of credit policy administration of the bank while insider ownership set the directions of the bank. NPL is more of the result of the day to day operations of a bank. However, NPL and insider ownership are positively related. This may be explained by some banks having DOSRI (Directors, Owners, Stockholders and Related Interests) loans incurred in earlier years that are non-performing. Over the five-year period, banks were able to reduce their non performing loan ratios.

Return on equity and insider ownership have a negative relationship which is consistent with the findings of Yeo et al (2002) and Gul and Wah (2002) as cited by Korczak and Korczak(2009) and Kuznetsov, Kapelyushnikov, Dyomina (2008). These studies showed that the association between earnings and managerial ownership is negative at higher levels of managerial shareholdings and at blockholder controlled ownership.

The significant variables include bank size, eps, and return on asset (ROA). Bank size and ROA are positively related to insider ownership while EPS is negatively related. Kuznetsov, Kapelyushnikov, Dyomina (2008) used size as a control variable and their regression coefficients for the SIZE are positive and significant. In this study, the positive relationship between bank size and insider ownership can be a sign that large firms in the sample have larger insider ownership concentration and have better investment capabilities.

The positive relationship between insider ownership and ROA are consistent with Korczak and Korczak (2009),Kuznetsov, Kapelyushnikov, Dyomina (2008). Family controlled firms have higher profitability (as proxied by Return on assets).

Earnings per share and insider ownership are negatively related. This result is similar to ROE and insider ownership, where there is a negative relationship. As stated earlier, in cases of higher levels of managerial shareholdings in the US, Singapore and Russia, the relationship of earnings and managerial ownership is negative (Korczak and Korczak(2009) and Kuznetsov, Kapelyushnikov, Dyomina (2008).

The results of Model 2 where board size proxies for corporate governance resulted to the following significant variables: Independent directors, EPS, ROA, and ROE. The insignificant variables are bank age, bank size, npl.

Bank age has nothing to do with the board size. The increase in the number of directors is usually for board control although other factors are also taken into consideration. Also, bank size is insignificant because it is the Asset Liability Committee (ALCO) that sets interest rates of the bank, investment policy, pricing issues, liquidity management. ALCO is composed mostly of senior managers of the bank and it is only the bank President/Chief Executive Officer (CEO) that is part of the Board. ALCO reports to the board their policies, if there are changes, they will be prospective rather than retrospective. ALCO meets regularly (once a week) as compared to the board that meets only twice a month

NPL, similar to bank size is insignificant. NPL is a result of day to day operation of any bank although the board sets the strategic directions.

Independent directors, as a variable, is significant, implying that the more independent directors in the board, the greater the ability to monitor activities of management and protect shareholders' interest and enhance corporate governance.(Leung and Horwitz 2004). They can offer other viewpoints or /strategies than what the bank may be used to. Independent directors also serve as a deterrent to immediate and costly reactions during the crisis.

Earnings, returns ratio (EPS, ROA, ROE) are significant. However, ROE and EPS are negatively related to board size. Listed Philippine banks are often characterized as having concentrated ownership by insider ownership, a majority is part of the board of directors. As individual insider ownership, there is a clear representation of ownership. However, as individuals who are part of institutions that are also insider ownership, the representation of ownership may not be clear. As earlier stated, only the President/CEO is part of the ALCO, thus, there is board representation in the decisions that affect ROE and EPS. The findings on ROE and EPS are consistent with Leung and Horwitz (2004)findings where East Asian firms have high concentrated ownership resulting to lower informativeness of earnings as reflected in the earnings-return relation.

In 2008, the global financial crisis sent banks and investment banks either declaring bankruptcy or being bailed out. For the Philippine banking system, the Bangko Sentral ng Pilipinas (BSP) reported that only the banks with collaterized debt obligations were affected by the crisis and not one collapsed as a result of the crisis. After the 1997 Asian Financial Crisis, Asian banks adopted reforms particularly on corporate governance. Initially, there was resistance to corporate governance since banks in Asia are owned by taipans or families. Eventually, banks adopted leading practices and principles of corporate governance. These included transparency, accountability, fairness/equity, risk management, independent board of directors. These corporate governance practices cushioned the impact of the global financial crisis for Philippine banks.

SUMMARY AND CONCLUSION

The paper analyzed the relationship of corporate governance with bank size, age, non performing loan ratio, earnings per share, return on average assets, return on average equity and independent directors. Our findings showed that corporate governance as proxied by insider ownership has significant relationship with ROA, bank size and EPS. Both bank size and ROA are positively related while EPS is negatively related to corporate governance. And we summarized that corporate governance as proxied by board size has significant relationship with independent board, EPS, ROA and ROE. Both independent board and ROA are positively related while EPS and ROE are negatively related to corporate governance.

Philippine banks were minimally affected by the Global Financial Crisis in 2008 since they have corporate governance structures in place. The findings showed that the presence of independent directors in the board suggests effectiveness in increasing disclosure, transparency, enhancing corporate governance. Also, the reduction of non-performing loans ratios over the years since the 1997 Asian Financial Crisis showed that banks monitor the quality of their loans, disposing of the non performing assets through special asset vehicles. Philippine banks are cautious about lending and exposures to risky assets which is why they were minimally affected by the Global financial crisis.

Although ownership of Philippine banks is still largely concentrated, it is not a deterrent against improving corporate governance which resulted to higher profitability. With greater transparency demanded of them, Philippine banks focus more on coming up with client friendly products and services instead of simply increasing their asset size just to be the biggest but without concern for good corporate governance.
