CHAPTER ONE
INTRODUCTION
1.1 Background
of the Study
Corporate governance is concerned with the ways in
which the shareholders of corporations assure themselves of getting a return on
their investment (Shleifer and Vishny, 1997). It also
deals with the mechanisms by which shareholders of a corporation exercise
control over management such that the interests of the shareholders are
protected (John and Senbet, 1998). The organisation for Economic Cooperation
and Development (OECD) Principles of Corporate Governance (2004) define
corporate governance as involving “a set of relationships between a company’s
management, its board, its shareholders, and other stakeholders”. Corporate
governance also provides the structures through which the objectives of the
company are set, the means of determining the attainment of those objectives,
and establishing performance-monitoring mechanisms. OECD (2004) also posits
that good corporate governance should provide proper incentives for the board
and management to pursue objectives that are in the interests of the company
and its shareholders, and should facilitate effective monitoring. The presence
of an effective corporate governance system, within an individual company and
across an economy as a whole, helps to provide a degree of confidence that is
necessary for the proper functioning of a market economy. Corporate governance
is, therefore, about what the board of a company does and how it sets the
values of the company, and is to be distinguished from the day-to-day
operational management of the company by full-time executives (Financial
Reporting Council, 2010).
Corporate
governance research is influenced by the agency theory. The primary reason for
corporate governance is the separation of ownership and control, and the agency
problem it engenders (John and Senbet, 1998). Agency cost arises in
organisations where the owners (shareholders) are not the managers. Usually,
the interests of shareholders may not wholly match the interests of managers.
Shareholders are interested in maximizing the value of the firm, but managers’
objectives may also include the increase in perquisite consumption and job
security (Belkhir, 2006). Given various
attributes of the management-shareholder relationship, corporate governance
mechanisms such as equity ownership by managers (Jensen and Meckling, 1976);
equity ownership by outside blockholders (Kaplan and Minton, 1994);
executive compensation (Mehran, 1995); compensation contracts (Adams and
Mehran, 2003), among others, may help align the interest of managers with those
of shareholders, thereby mitigating the agency problem. In addition, the board
of directors also may play a central role in monitoring managers (Fama, 1980),
and minimizing losses in shareholders’ interest (Nicholson and Kiel, 2004).
Hence, the board is known as one of the most important instruments of solving
the corporate governance problem (Jensen, 1993).
Since
the mid-1980S, the issue of corporate governance has attracted a
great deal of attention both in academic research and in practice (Levrau and
Van den Berghe, 2007). Corporate scandals across the world, especially in
Europe and America, such as Adelphia Communications, Arthur Anderson, Enron,
Health South, Tyco, WorldCom and Ahold, among others, set off a fresh round of
debate on the effectiveness of corporate governance laws, which also shifted
the spotlight to the board of directors (Levrau and Van den Berghe, 2007). In
the wake of these series of high profile scandals, the Sabones-Oxley Act 2002
(SOX) was passed in the United States of America (Dalton and Dalton, 2007;
Romano, (2005), and similar regulations in other jurisdictions.
Corporate
governance has also been at the forefront of the policy agenda of international
bodies. The OECD, in 1999, promulgated the Principles of Corporate Governance,
which was revised in 2004 (OECD, 2004). Similarly, the European Association of
Securities Dealers (EASD), in 2000, issued the Corporate Governance Principles
and Recommendations, while the International Corporate Governance Network
(ICGN), in 2005, issued the Statement on Global Corporate Governance
Principles, revising its 1999 version (EASD, 2000; ICGN, 2005). Also, the Basel
Committee on Banking Supervision promulgated a set of corporate governance
principles in 1999, which was revised in 2006, following the 2005 Consultative
Document (see Basel Committee on Banking Supervision, 1999, 2005, 2006). One of
the major objectives of these recommendations is the design of an optimal board
structure that would prevent the failure of the firms’ governance, as well as
maximize their financial performance.
In
Nigeria, the Central Bank of Nigeria, CBN, in 2006, responded to this trend by
establishing the Code of Corporate Governance for Banks in Nigeria Post
Consolidation.The major recommendations of the code include:that the board
should have a minimum of four meetings in a financial year; that the number of
non-executive directors should be more than that of executive directorsand that,
bank board size should not be more than twenty, among others.
The
rationale for these recommendations was to make commercial bank boards in
Nigeria effective. However, the recent
global financial crisis, which also triggered banking crisis in Nigeria, has come
as a surprise to practitioners and scholars given the low level of integration
of the Nigeria financial system to the global financial market. Investigation
carried out by the Central Bank of Nigeria revealed that the causes of the
post-consolidation crisis were as a result of macro-economic instability caused
by large and sudden capital inflows; major failures in corporate governance at
banks; lack of investor and customer sophistication; inadequate disclosure and
transparency about financial position of banks; critical gaps in regulatory
framework and regulations; uneven supervision and enforcement; unstructured
governance and management processes at the CBN/weakness within the CBN; and
weaknesses in the business environment (Sanusi, 2010). According to Sanusi
(2010), failure in corporate governance of banks was, indeed, a principal
factor contributing to the financial crisis in Nigeria. This raises an
important research question on the effectiveness of the recommendations of the
Code of Corporate Governance for Banks in Nigeria Post Consolidation in
promoting good corporate governance among Nigerian banks.
Corporate
governance of banks is important for banks themselves as well as for the whole
economy (Caprio and Levine, 2002). First of all, banks are themselves
corporations. Sound corporate governance is essential for banks to perform
efficiently. Moreover, since banks exert a strong impact on economic
development (Levine 1997), corporate governance of banks is crucial for growth
and development. Banks play a central role in mobilizing the social savings and
channeling them to the most productive projects. Bank lending is a major source
of external finance for other firms, especially in developing and emerging
economies. Sound corporate governance of banks is essential for bank managers
to allocate social capital efficiently and to enhance the performance of the
economy. Banks also play a critical role in the corporate governance of other
firms (Franks and Mayer, 2001; Santos and Rumble, 2006), as creditors or equity
holders of firms. Thus, it is also essential that banks, themselves, face sound
corporate governance so that they can exert effective governance over the firms
they fund.
As
suggested by both practitioners and academicians, banks’ governance mechanisms
are key factors influencing bank performance. Research on governance issues
related to banks has been limited, as prior research tends to focus on firms in
the non-financial sector (Handley-Schachler et al., 2001; Adams and Mehran,
2003). Hence, only few papers focus on bank corporate governance and its
association with performance (e.g. Adams and Mehran, 2005; Caprio et al, 2007,
Levine, 2004; Macey and O’Hara, 2003; Andres and Vallelado, 2008; Dahya et al.,
2008).This could be attributed to the peculiar nature of bank governance
problem.
The
nature of corporate governance problems in banking is different from
non-banking firms. Research offers several reasons which make bank corporate
governance peculiar. First, banks, due to their special nature have wider
stakeholders. In addition to shareholders, the interest of depositors has to be
addressed (Macey and O’Hara, 2003) and, also, that of regulators who ensure
sound financial system (Boot and Thakor, 1993). Hence, bank directors are accountable
not only to shareholders, but also to depositors and regulators (Subrahmanyam,
et al., 1997). Second, banks’ high leverage and, mismatch between term
structure and liquidity of their assets and liabilities make their role in the
economy very important. Third, the agency problems are particularly crucial for
banks as they are informationally opaque (Levine, 2003; Caprio and Levine,
2002) largely because of information asymmetries (Furfine, 2001). Fourth,
deposit insurance makes the situation worse by ameliorating the ‘moral hazard’
problem among bank shareholders and debt-holders. In the presence of deposit
insurance, the depositors or debt-holders may have less incentive to monitor
bank managers. Deposit insurance may similarly distort the bank’s investment
and financing process as bank managers and shareholders may have added
incentives to take more risks (Merton, 1977). Demirgüç-Kunt and Detragiache
(2002) argue that countries with more generous deposit insurance schemes tend
to have a higher likelihood of banking crises. Finally, Skully (2002) contends
that bank corporate governance is particularly important because it reduces the
risk of taxpayer funds being used in mitigating a crisis and helps restrain
connected lending.
Among
other characteristics of the board, size, composition, and activity have
received special attention, in academic literature (Andres and Vallelado, 2008).
An extensive body of empirical research has examined the effect of board size
(Yermack, 1996; Provan, 1980; Dalton et al., 1999; Lee and Filbeck, 2006;
Jensen, 1993; Fernandez et al, 1997; Adams and Mehran, 2003, 2005, 2008;
Huther, 1997; Eisenberg et al, 1998), composition (Kesner, 1987; Baysinger and
Butler, 1985; Hermalin and Weisbach, 1988, 1991, 2003; Weisbach, 1988; Rosenstein
and Wyatt, 1990, 1997; Bhagat and Black, 1999) and number of meetings (Klein,
1998; Vafeas, 1999; Adams and Mehran, 2003) on firm performance. Empirical
evidence along this line remains inconclusive. It has been argued that a larger
board of directors is beneficial and will increase the collection of expertise
and resources accessible to a firm (Dalton et al., 1999). Belkhir (2009)
reports that a larger bank board is positively associated with firm performance
as measured by return on assets and Tobin’s Q. However, Hermalin and Weisbach
(2003) argue that a larger board will impair firm performance. Jensen (1993)
concludes that the effectiveness of a board may decline as board size increases.
On the one hand, non-executive directors could be more motivated to monitor the
CEO; but on the other hand, they might also be less informed about the running
of the business (Bahgat and Black, 1999; Adams and Ferreira, 2007). Regarding
board activity, the frequency of board meetings is suggested to indicate active
monitoring by the board (Conger et al., 1998). Contrary to this perspective,
Vafeas (1999) found that frequency of board meetings is negatively related to
performance, which may be the result of boards meeting more often subsequent to
poor performance.
It
is evident that most of the works reviewed used data from developed economies.
This study presented evidence from Nigeria, one of the emerging markets in the
world. Given the recent banking crisis in Nigeria and the revelation by CBN
that the principal cause of the crisis is governance problem, it becomes
important to evaluate the effectiveness of the major recommendations of the
Code of Corporate Governance for Banks in Nigeria Post Consolidation. This
study sought to fill this important research gap by evaluating the impact of board size, board composition and board
activity on the financial performance of banks in Nigeria using
a population sample of all the 24 commercial banks for the period 2006 – 2010.
1.2 Statement of the Problem
Less
than a decade after the Enron scandal, the recent global financial crisis has
raised a lot of questions on the effectiveness of the governance mechanisms in
the banking industry. It has brought to bear the harmful consequences of poor
governance principles in financial business. Poor corporate governance may
contribute to bank failures, loss of confidence by the market, bank run or
liquidity crisis which can pose broader macroeconomic implications, such as
contagion risk and impact on the payment systems (Basel Committee on Banking
Supervision, 2006). A bank which becomes less attractive for investment
purposes will shortly lose employees and customers (Spremann, 2005 P: 39).
Furthermore, it will become a candidate for acquisition.
For
a developing country like Nigeria, corporate governance in the banking sector
is of critical importance. This is evident in the recent banking crisis which
has been arguably described as the worse in the history of the country (Uche,
2010). In 2009, following the banking system crisis which was largely caused by
poor corporate governance practices, some Nigerian banks had to be rescued
through the injection of N620 billion
of liquidity by the CBN (Sanusi, 2010). This high-profile governance problem
occurred after the CBN had adopted the Code of Corporate Governance for Banks
in Nigeria Post Consolation. This raises an important question on the
effectiveness of the prescriptions of such code.
It has been established that Nigeria, like most developing economies, has weak market institutions, weak external governance laws and poor implementation of promulgated laws. Thus, effective corporate governance laws must incorporate the country’s institutional specifics in making bank boardeffective. Such laws must be influenced by studies in local jurisdiction instead of wholesome adoption of the recommendations of studies in developed economies. This study fills this important research gap by estimating the effectiveness of corporate boards in the Nigerian banking industry using Nigerian data. Specifically, the study evaluated the recommendations of the Code of Corporate Governance for Banks in Nigeria Post Consolation in enhancing bank board effectiveness in Nigeria.
