CORPORATE GOVERNANCE AND FINANCIAL PERFORMANCE OF BANKS: A STUDY OF LISTED BANKS IN NIGERIA
An international wave of mergers and acquisitions has swept the banking industry as boundaries between financial sectors and products have blurred dramatically. There is therefore the need for countries to have sound resilient banking systems with good corporate governance, which will strengthen and upgrade the institution to survive in an increasingly open environment. In Nigeria, the Central Bank unveiled new banking guidelines designed to consolidate and restructure the industry through mergers and acquisition. This was to make Nigerian banks more competitive and be able to operate in the global market. Despite all its attempts, the Central Bank of Nigeria disclosed that after the consolidation in 2006, 741 cases of attempted fraud and forgery involving N5.4 billion were reported. In the light of the above, this research examined the relationships that exist between governance mechanisms and financial performance in the Nigerian consolidated banks. And also to find out if there is any significant relationship between the level of corporate governance disclosure index among Nigerian banks and their performance. The Pearson Correlation and the regression analysis were used to find out whether there is a relationship between the corporate governance variables and firm’s performance. In examining the level of corporate governance disclosures of the sampled banks, a disclosure index was developed guided by the CBN code of governance and also on the basis of the papers prepared by the UN secretariat for the nineteenth session of ISAR (International Standards of Accounting and Reporting). The study therefore observed that a negative but significant relationship exists between board size, board composition and the financial performance of these banks, while a positive and significant relationship was also noticed between directors’ equity interest, level of governance disclosure and performance. Furthermore, the t- test result indicated that while a significant difference was observed in the profitability of the healthy banks and the rescued banks, no difference was seen in the profitability of banks with foreign directors and that of banks without foreign directors. The study therefore concludes thatthere is no uniformity in the disclosure of corporate governance practices by the banks. Likewise, the banks do not disclose in general how their debts are performing, by providing a statement that expresses outstanding debts in terms of their ages and due dates. The study suggests that efforts to improve corporate governance should focus on the value of the stock ownership of board members. Also, steps should be taken for mandatory compliance with the code of corporate governance while an effective legal framework should be developed that specifies the rights and obligations of a bank, its directors, shareholders, specific disclosure requirements and provide for effective enforcement of the law.
1.0 Background to the Study
Globalization and technology have continuing speed which makes the financial arena to become more open to new products and services invented. However, financial regulators everywhere are scrambling to assess the changes and master the turbulence (Sandeep, Patel and Lilicare, 2002:9). An international wave of mergers and acquisitions has also swept the banking industry. In line with these changes, the fact remains unchanged that there is the need for countries to have sound resilient banking systems with good corporate governance. This will strengthen and upgrade the institution to survive in an increasingly open environment (Qi, Wu and Zhang, 2000; Köke and Renneboog, 2002 and Kashif, 2008).
Given the fury of activities that have affected the efforts of banks to comply with the various consolidation policies and the antecedents of some operators in the system, there are concerns on the need to strengthen corporate governance in banks. This will boost public confidence and ensure efficient and effective functioning of the banking system (Soludo, 2004a). According to Heidi and Marleen (2003:4), banking supervision cannot function well if sound corporate governance is not in place. Consequently, banking supervisors have strong interest in ensuring that there is effective corporate governance at every banking organization. As opined by Mayes, Halme and Aarno (2001), changes in bank ownership during the 1990s and early 2000s substantially altered governance of the world’s banking organization. These changes in the corporate governance of banks raised very important policy research questions. The fundamental question is how do these changes affect bank performance?
It is therefore necessary to point out that the concept of corporate governance of banks and very large firms have been a priority on the policy agenda in developed market economies for over a decade. Further to that, the concept is gradually warming itself as a priority in the African continent. Indeed, it is believed that the Asian crisis and the relative poor performance of the corporate sector in Africa have made the issue of corporate governance a catchphrase in the development debate (Berglof and Von -Thadden, 1999).
Several events are therefore responsible for the heightened interest in corporate governance especially in both developed and developing countries. The subject of corporate governance leapt to global business limelight from relative obscurity after a string of collapses of high profile companies. Enron, the Houston, Texas based energy giant and WorldCom the telecom behemoth, shocked the business world with both the scale and age of their unethical and illegal operations. These organizations seemed to indicate only the tip of a dangerous iceberg. While corporate practices in the US companies came under attack, it appeared that the problem was far more widespread. Large and trusted companies from Parmalat in Italy to the multinational newspaper group Hollinger Inc., Adephia Communications Company, Global Crossing Limited and Tyco International Limited, revealed significant and deep-rooted problems in their corporate governance. Even the prestigious New York Stock Exchange had to remove its director (Dick Grasso) amidst public outcry over excessive compensation (La Porta, Lopez and Shleifer 1999).
In developing economies, the banking sector among other sectors has also witnessed several cases of collapses, some of which include the Alpha Merchant Bank Ltd, Savannah Bank Plc, Societe Generale Bank Ltd (all in Nigeria), The Continental Bank of Kenya Ltd, Capital Finance Ltd, Consolidated Bank of Kenya Ltd and Trust Bank of Kenya among others (Akpan, 2007).
In Nigeria, the issue of corporate governance has been given the front burner status by all sectors of the economy. For instance, the Securities and Exchange Commission (SEC) set up the Peterside Committee on corporate governance in public companies. The Bankers’ Committee also set up a sub-committee on corporate governance for banks and other financial institutions in Nigeria. This is in recognition of the critical role of corporate governance in the success or failure of companies (Ogbechie, 2006:6). Corporate governance therefore refers to the processes and structures by which the business and affairs of institutions are directed and managed, in order to improve long term share holders’ value by enhancing corporate performance and accountability, while taking into account the interest of other stakeholders (Jenkinson and Mayer, 1992). Corporate governance is therefore, about building credibility, ensuring transparency and accountability as well as maintaining an effective channel of information disclosure that will foster good corporate performance.
Jensen and Meckling (1976) acknowledged that the principal-agent theory which was also adopted in this study is generally considered as the starting point for any debate on the issue of corporate governance. A number of corporate governance mechanisms have been proposed to ameliorate the principal-agent problem between managers and their shareholders. These governance mechanisms as identified in agency theory include board size, board composition, CEO pay performance sensitivity, directors’ ownership and share holder right (Gomper, Ishii and Metrick, 2003). They further suggest that changing these governance mechanisms would cause managers to better align their interests with that of the shareholders thereby resulting in higher firm value.
Although corporate governance in developing economies has recently received a lot of attention in the literature (Lin (2000); Goswami (2001); Oman (2001); Malherbe and Segal (2001); Carter, Colin and Lorsch (2004); Staikouras, Maria-Eleni, Agoraki, Manthos and Panagiotis (2007); McConnell, Servaes and Lins (2008) and Bebchuk, Cohen and Ferrell (2009), yet corporate governance of banks in developing economies as it relates to their financial performance has almost been ignored by researchers (Caprio and Levine (2002); Ntim (2009). Even in developed economies, the corporate governance of banks and their financial performance has only been discussed recently in the literature (Macey and O’Hara, 2001).
The few studies on bank corporate governance narrowly focused on a single aspect of governance, such as the role of directors or that of stock holders, while omitting other factors and interactions that may be important within the governance framework. Feasible among these few studies is the one by Adams and Mehran (2002) for a sample of US companies, where they examined the effects of board size and composition on value. Another weakness is that such research is often limited to the largest, actively traded organizations- many of which show little variation in their ownership, management and board structure and also measure performance as market value.
In Nigeria, among the few empirically feasible studies on corporate governance are the studies by Sanda and Mukailu and Garba (2005) and Ogbechie (2006) that studied the corporate governance mechanisms and firms’ performance. In order to address these deficiencies, this study examined the role of corporate governance in the financial performance of Nigerian banks. Unlike other prior studies, this study is not restricted to the framework of the Organization for Economic Cooperation and Development principles, which is based primarily on shareholder sovereignty. It analysed the level of compliance of code of corporate governance in Nigerian banks with the Central Bank’s post consolidated code of corporate governance. Finally, while other studies on corporate governance neglected the operating performance variable as proxies for performance, this study employed the accounting operating performance variables to investigate the relationship if any, that exists between corporate governance and performance of banks in Nigeria.
1.1 Statement of Research Problem
Banks and other financial intermediaries are at the heart of the world’s recent financial crisis. The deterioration of their asset portfolios, largely due to distorted credit management, was one of the main structural sources of the crisis (Fries, Neven and Seabright, 2002; Kashif, 2008 and Sanusi, 2010). To a large extent, this problem was the result of poor corporate governance in countries’ banking institutions and industrial groups. Schjoedt (2000) observed that this poor corporate governance, in turn, was very much attributable to the relationships among the government, banks and big businesses as well as the organizational structure of businesses.
In some countries (for example Iran and Kuwait), banks were part of larger family-controlled business groups and are abused as a tool of maximizing the family interests rather than the interests of all shareholders and other stakeholders. In other cases where private ownership concentration was not allowed, the banks were heavily interfered with and controlled by the government even without any ownership share (Williamson, 1970; Zahra, 1996 and Yeung, 2000). Understandably in either case, corporate governance was very poor. The symbiotic relationships between the government or political circle, banks and big businesses also contributed to the maintenance of lax prudential regulation, weak bankruptcy codes and poor corporate governance rules and regulations (Das and Ghosh, 2004; Bai, Liu, Lu, Song and Zhang, 2003).
In Nigeria, before the consolidation exercise, the banking industry had about 89 active players whose overall performance led to sagging of customers’ confidence. There was lingering distress in the industry, the supervisory structures were inadequate and there were cases of official recklessness amongst the managers and directors, while the industry was notorious for ethical abuses (Akpan, 2007). Poor corporate governance was identified as one of the major factors in virtually all known instances of bank distress in the country. Weak corporate governance was seen manifesting in form of weak internal control systems, excessive risk taking, override of internal control measures, absence of or non-adherence to limits of authority, disregard for cannons of prudent lending, absence of risk management processes, insider abuses and fraudulent practices remain a worrisome feature of the banking system (Soludo, 2004b). This view is supported by the Nigeria Security and Exchange Commission (SEC) survey in April 2004, which shows that corporate governance was at a rudimentary stage, as only about 40% of quoted companies including banks had recognised codes of corporate governance in place. This, as suggested by the study may hinder the public trust particularly in the Nigerian banks if proper measures are not put in place by regulatory bodies.
The Central Bank of Nigeria (CBN) in July 2004 unveiled new banking guidelines designed to consolidate and restructure the industry through mergers and acquisition. This was to make Nigerian banks more competitive and be able to play in the global market. However, the successful operation in the global market requires accountability, transparency and respect for the rule of law. In section one of the Code of Corporate Governance for banks in Nigerian post consolidation (2006), it was stated that the industry consolidation poses additional corporate governance challenges arising from integration processes, Information Technology and culture. The code further indicate that two-thirds of mergers world-wide failed due to inability to integrate personnel and systems and also as a result of the irreconcilable differences in corporate culture and management, resulting in Board of Management squabbles.
Despite all these measures, the problem of corporate governance still remains un-resolved among consolidated Nigerian banks, thereby increasing the level of fraud (Akpan, 2007) see Appendix 2. Akpan (2007) further disclosed that data from the National Deposit Insurance Commission report (2006) shows 741 cases of attempted fraud and forgery involving N5.4 billion. Soludo (2004b) also opined that a good corporate governance practice in the banking industry is imperative, if the industry is to effectively play a key role in the overall development of Nigeria.
The causes of the recent global financial crises have been traced to global imbalances in trade and financial sector as well as wealth and income inequalities (Goddard, 2008). More importantly, Caprio, Laeven & Levine (2008) opined that there should be a revision of bank supervision and corporate governance reforms to ensure that deliberate transparency reductions and risk mispricing are acted upon.
Furthermore, according to Sanusi (2010), the current banking crises in Nigeria, has been linked with governance malpractice within the consolidated banks which has therefore become a way of life in large parts of the sector. He further opined that corporate governance in many banks failed because boards ignored these practices for reasons including being misled by executive management, participating themselves in obtaining un-secured loans at the expense of depositors and not having the qualifications to enforce good governance on bank management.
The boards of directors were further criticized for the decline in shareholders’ wealth and corporate failure. They were said to have been in the spotlight for the fraud cases that had resulted in the failure of major corporations, such as Enron, WorldCom and Global Crossing.
The series of widely publicized cases of accounting improprieties recorded in the Nigerian banking industry in 2009 (for example, Oceanic Bank, Intercontinental Bank, Union Bank, Afri Bank, Fin Bank and Spring Bank) were related to the lack of vigilant oversight functions by the boards of directors, the board relinquishing control to corporate managers who pursue their own self-interests and the board being remiss in its accountability to stakeholders (Uadiale, 2010). Inan (2009) also confirmed that in some cases, these bank directors’ equity ownership is low in other to avoid signing blank share transfer forms to transfer share ownership to the bank for debts owed banks. He further opined that the relevance of non- executive directors may be watered down if they are bought over, since, in any case, they are been paid by the banks they are expected to oversee.
As a result, various corporate governance reforms have been specifically emphasized on appropriate changes to be made to the board of directors in terms of its composition, size and structure (Abidin, Kamal and Jusoff, 2009).
It is in the light of the above problems, that this research work studied the effects of corporate governance mechanisms on the financial performance of banks in Nigeria and also reviewed the annual reports of the listed banks in Nigeria to find out their level of compliance with the CBN (2006) post consolidation code of corporate governance. The study also finds out if there is any statistically significant difference between the profitability of the healthy and the rescued banks in Nigeria as listed by CBN in 2009. Finally, it went further to investigate if the banks with foreign directors perform better than those without foreign directors.
1.2 Objectives of Study
Generally, this study seeks to explore the relationship between internal corporate governance structures and firm financial performance in the Nigerian banking industry. However, it is set to achieve the following specific objectives:
1a) To examine the relationship between board size and financial performance of banks in Nigeria.
1b) To find out if there is a significant difference in the financial performance of banks with foreign directors and banks without foreign directors in Nigeria
2) To appraise the effect of the proportion of non- executive directors on the financial performance of banks in Nigeria.
3) To investigate if there is any significant relationship between directors’ equity interest and the financial performance of banks in Nigeria.
4) To empirically determine if there is any significant relationship between the level of corporate governance disclosure and the financial performance of banks in Nigerian.
5) To investigate if there is any significant difference between the profitability of the healthy banks and the rescued banks in Nigeria.
1.3 Research Questions
This study addressed issues relating to the following pertinent questions emerging within the domain of study problems:
1a) To what extent (if any) does board size affect and the financial performance of banks in Nigeria?
1b) Is there a significant difference in the financial performance of banks with foreign directors and banks without foreign directors in Nigeria.
2) Is the relationship between the proportion of non-executive directors and the financial performance of listed banks in Nigeria statistically significant?
3) Is there a significant relationship between directors’ equity holdings and the financial performance of banks in Nigeria?
4) To what extent does the level of corporate governance disclosure affect the performance of banks in Nigeria?
5) To what extent (if any) does the profitability of the healthy banks differ from that of the rescued banks in Nigeria?
To proffer useful answers to the research questions and realize the study objectives, the following hypotheses stated in their null forms will be tested;
H0: There is no significant relationship between board size and financial
performance of banks in Nigeria
H0: There is no significant difference in the financial performance of banks with foreign directors and banks without foreign directors in Nigeria
H0: The relationship between the proportion of non executive directors and the financial performance of Nigerian banks is statistically not significant
H0: There is no significant relationship between directors’ equity holding and the financial performance of banks in Nigeria
H0: There is no significant relationship between the governance disclosures of banks in Nigeria and their performance
H0: There is no significant difference between the profitability of the healthy and the rescued banks in Nigeria
1.5 Significance of the Study
This study is of immense value to bank regulators, investors, academics and other relevant stakeholders. By introducing a summary index that is better linked to firm performance than the widely used G-index, the study provides future researchers with an alternative summary measure. This study provides a picture of where banks stand in relation to the codes and principles on corporate governance introduced by the Central Bank of Nigeria. It further provides an insight into understanding the degree to which the banks that are reporting on their corporate governance have been compliant with different sections of the codes of best practice and where they are experiencing difficulties. Boards of directors will find the information of value in benchmarking the performance of their banks, against that of their peers. The result of this study will also serve as a data base for further researchers in this field of research.
1.6 Justification of Study
Generally, banks occupy an important position in the economic equation of any country such that its (good or poor) performance invariably affects the economy of the country. Poor corporate governance may contribute to bank failures, which can increase public costs significantly and consequences due to their potential impact on any applicable system. Poor corporate governance can also lead markets to lose confidence in the ability of a bank to properly manage its assets and liabilities, including deposits, which could in turn trigger liquidity crisis.
From the preceding discussions, it is evident that the question of ideal governance mechanism (board size, board composition and directors equity interest) is highly debatable. Since performance of a firm, as identified by Das and Gosh (2004), depends on the effectiveness of these mechanisms, there is a need to further explore this area. Although researchers have tried to find out the effects of board size and other variables on the performance of firms, they are mostly in context of developed markets. To the best of the researcher’s knowledge based on the literatures reviewed, only few studies were found in the context of Nigerian banks. Due to neglect of banking sector by other studies and with radical changes in Nigerian banking sector in the last few years, present study aims to fill the existing gap in corporate governance literatures.
Studies on bank governance are therefore important because banks play important monitoring and governance roles for their corporate clients to safeguard their credit against corporate financial distress and bankruptcy. An expose by Prowse (1997) shows that research on corporate governance applied to financial intermediaries especially banks, is indeed scarce. This shortage is confirmed in Oman (2001); Goswami (2001); Lin (2001); Malherbe and Segal (2001) and Arun and Turner (2002). They held a consensus that although the subject of corporate governance in developing economies has recently received a lot of attention in the literature, however, the corporate governance of banks in developing economies has been almost ignored by researchers. The idea was also shared by Caprio and Levine (2001). Macey and O’Hara (2002) shared the same opinion and noted that even in developed economies; the corporate governance of banks has only recently been discussed in the literature. To the best of the researchers knowledge, apart from the few studies by Caprio and Levine (2002), Peek and Rosengren (2000) on corporate governance and bank performance, very little or no empirical studies have been carried out specifically on this subject especially in developing economies like Nigeria. A similar study carried out in Nigeria was by Sanda, Mukailu and Garba (2005) where they looked at corporate governance and the financial performance of nonfinancial firms. This scarcity of research effort demands urgent intervention, which therefore justifies the importance of this study, which intends to provide guidance in corporate governance of banks. Furthermore, banks are very opaque, which makes the information asymmetry and the agency problem particularly serious (Biserka, 2007). This also necessitates the study on bank governance.
1.7 Scope and Limitation of Study
Considering the year 2006 as the year of initiation of post consolidation governance codes for the Nigerian banking sector, this study investigates the relationship between corporate governance and financial performance of banks. The choice of this sector is based on the fact that the banking sector’s stability has a large positive externality and banks are the key institutions maintaining the payment system of an economy that is essential for the stability of the financial sector. Financial sector stability, in turn has a profound externality on the economy as a whole. To this end, the study basically covers the 21 listed banks out of the 24 universal banks, operating in Nigeria till date that met the N25 billion capitalization dead-line of 2005. The study covers these banks’ activities during the post consolidation period i.e. 2006-2008. The choice of this period allows for a significant lag period for banks to have reviewed and implemented the recommendations by the CBN post consolidation code. However it was not possible to obtain the annual reports of 2009/2010 since they are yet to be published by many of the banks as at the time of this research.
Furthermore, we focused only on banking industry because corporate governance problems and transparency issues are important in the banking sector due to the crucial role in providing loans to non-financial firms, in transmitting the effects of monetary policy and in providing stability to the economy as a whole. The study therefore covers four key governance variables which are board size, board composition, directors’ equity interest and governance disclosure level.
1.8 Summary of Research Methodology
This study made use of secondary data in establishing the relationship between corporate governance and financial performance of the 21 banks listed in the Nigerian Stock Exchange. The secondary data is obtained basically from published annual reports of these banks. Books and other related materials especially the Central Bank of Nigeria bullions and the Nigerian Stock Exchange Fact Book for 2008 were also reviewed.
In analyzing the relationship that exists between corporate governance and the financial performance of the studied banks, a panel data regression analysis method was adopted. The Pearson correlation was used to measure the degree of association between variables under consideration. However, the proxies that were used for corporate governance are: board size, the proportion of non executive directors, directors’ equity interest and corporate governance disclosure index. Proxies for the financial performance of the banks also include the accounting measure of performance; return on equity (ROE) and return on asset (ROA) as identified by First Rand Banking Group (2006). To examine the level of corporate governance disclosures of the sampled banks, the content analysis method was used. Using the content analysis, a disclosure index is developed for each bank using the Nigerian post consolidation code and the Organization for Economic Cooperation and Development (OECD) code of corporate governance as a guide. This was used alongside with the papers prepared by the UN Secretariat for the nineteenth and the twentieth session of International Standards of Accounting and Reporting (ISAR), entitled “Transparency and Disclosure Requirements for Corporate Governance” and “Guidance on Good Practices in Corporate Governance Disclosure” respectively.
The student t- test was used in analysing the difference in the performances of the healthy banks and the rescued banks. It was also used to determine if there is any significant difference in the performance of banks with foreign directors and that of banks without foreign directors.
1.9 Sources of Data
This study employed only the secondary data derived from the audited financial statements of the listed banks on the Nigerian Stock Exchange (NSE) in analyzing the relationship between our dependent and independent variables. The secondary data covers a period of three years i.e. 2006 and 2008. This study also made use of books and other related materials especially the Central Bank of Nigeria bullions and the Nigerian Stock Exchange Fact Book (2008). Some of the annual reports that were not available at the NSE were collected from the head offices of the concerned banks in addition to the downloaded materials from the banks’ websites.
The data that was used in analyzing the disclosure index was derived using the content analysis method to score the banks based on their disclosure level. This was done using the disclosure items developed through the use of the CBN and the OECD codes of corporate governance.
