ABSTRACT
This
empirical study, seeks to determine the impact of corporate governance
mechanisms on the performance of banks in Nigeria. An intensive review of
literature was conducted to identify the various aspects of corporate
governance and the roles they play in determining corporate performance. In
this study, board size and board independence represented corporate governance
while return on equity and return on assets proxied firm performance. The
Ordinary Least Squares (OLS) technique was applied on data gathered from 5
Commercial Banks firms over the period 2008 to 2012. The findings of this study
indicate that elements of corporate governance such as board size and board
independence have negative effects on the performance of firms, as measured by
the return on assets and return on equity.

CHAPTER
ONE
INTRODUCTION
1.1 BACKGROUND TO THE STUDY
Corporate Governance is the system by which
corporations are directed and controlled (Rezaee, 2009). The corporate
governance structure specifies the distribution of rights and responsibilities
among different participants in the corporation such as; boards, managers,
shareholders and other stakeholders and spells out the rules and procedures and
also decision making assistance on corporate affairs (Magdi and Nadereh, 2002).
By doing this, it also provides the structure through which the company
objectives are set, the means of obtaining those objectives and examining the
value and the performance of the firms. Effective corporate governance is
considered as ensuring corporate accountability, enhancing the reliability and
quality of financial information, and therefore enhancing the integrity and
efficiency of capital markets, which in turn will improve investors’ confidence
(Rezaee, 2009).
Corporate
governance involves a system by which governing institutions and all other
organizations relate to their communities and stakeholders to improve their
quality of life. (Ato, 2002). It is therefore important that good corporate
governance ensures transparency, accountability and fairness in reporting. In
this regard, corporate governance is not only concerned with corporate
efficiency, but also relates to a much wider range of company strategies and
life cycle development (Mayer, 2007). It is also concerned with the ways
parties (stake holders) interested in the wellbeing of firms ensure that managers
and other insiders adopt mechanisms to safeguard the interest of the
shareholders. (Ahmadu and Tukur, 2005). Corporate governance is based on the
level of corporate responsibility a company exhibits with regard to
accountability, transparency and ethical values. Corporate governance has also
been defined by Keasey et al (1997) to include, “the structures, processes,
cultures and systems that engender the successful operation of organizations”.
The definition could therefore be centered on how the organization relates with
other stake holders within an environment. Therefore, corporate governance
describes how companies ought to be run, directed and controlled (Cadbury
Committee, 1992). It is about supervising and holding to account those who
direct and control the management.
Corporate governance is an important effort to ensure
accountability and responsibility and a set of principles, which should be
incorporated into every part of the organization. Though it is viewed as a
recent issue, there is, in fact, nothing new about the concept. Corporate governance has been in existence as long as the
corporation itself – as long as there has been large–scale trade, reflecting
the need for responsibility in the handling of money and the conduct of
commercial activities (Metrick and Ishii, 2002).
Corporate governance has succeeded in attracting a great deal of interest as it
focuses not only on the long-term relationship, which has to deal with checks
and balances, incentives for managers and communications between management and
investors but also on transactional relationship, which involves dealing with
disclosure and authority (Tandelilin et
al. , 2007).
The challenge of corporate governance could help to align the
interests of individuals, corporations and society through a fundamental
ethical basis. This it will fulfill the long-term strategic goal of the owners,
which, after survival may consist of building shareholder value, establishing a
dominant market share or maintaining a technical lead in a chosen sphere (Yetman,2004). It will certainly not be the same for all organizations, but
will take into account the expectations of all the key stakeholders, in
particular: considering and caring for the interests of employees, customers
and suppliers, stockholders and debt holders, state and local community, both
in terms of the physical effects of the company’s operations and the economic
and cultural interaction with the population. The outcome of a
good corporate governance practice is an accountable board of directors who
ensures that the investors’ interests are not jeopardized (Hashanah and
Mazlina, 2005).
Desai
and Yetman (2004), identified two areas of agency problems that make human
ability to make allocative decision imperfect; the cognitive and behavioral
limitations. The cognitive limitation is hidden information, also known as
bounded rationality. This prevents investors from knowing a priori whether the
managers, whom they have employed as their agents, allocate resources in the
most efficient manner. The behavioral limitation, also known as opportunism, is
hidden action that reflects the productivity, inherent in an individualistic
society of managers as agents to use their positions for resources allocation
to pursue their own selfish interest and not necessarily the interest of the
firm’s principals. This makes it very crucial and important to study the
existence of the influence of corporate governance on the performance of firms.
1.2 STATEMENT OF 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 (Sanusi, 2010). 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 remained a worrisome feature of the banking
system (Soludo, 2004). The problem of corporate governance still
remains un-resolved among consolidated Nigerian banks, thereby increasing the
level of fraud (Akpan, 2007). 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
(Sanusi ,2010).
1.3
OBJECTIVES OF THE STUDY
The main objective of this study is
to ascertain
the impact of corporate governance on performance in Nigerian commercial banks.
To achieve this, the research is focused on the following specific objectives:
i. Examine the conceptual framework of corporate governance in commercial banks in Nigeria.
ii. Determine the extent of corporate governance
practices in operation in the banking sector
iii. Ascertain the impact
of Board Size on corporate performance.
iv. Determine how the level of independence of
directors influences the returns of banks.
v. Ascertain the factors that affect the
levels of governance adopted.
1.4 RESEARCH QUESTIONS
The study will
attempt to answer the following research questions:
i. To what extent do commercial banks in Nigeria practice and adhere to
corporate governance principles?
ii. Does the size of a
board have an impact on the corporate performance of banks in Nigeria?
iii. What influence does the
level of independence of boards have on bank’s performance?
iv. What are the reasons that make firms adopt different levels of governance
under the same level of investor protection?
1.5 RESEARCH HYPOTHESES
Hypothesis
One
H0: There is no significant relationship between the
size of a board and firm performance
in the banking sector in Nigeria
H1: There is a significant relationship between the size of a board and firm performance
in the banking sector in Nigeria
Hypothesis
Two
H0: Level of board independence has no
impact on firm performance in the banking sector
H1:. Level of
board independence impacts on firm performance in the banking sector
1.6 SIGNIFICANCE OF THE STUDY
The purpose of
this study would be to critically examine, and understand while analyzing
the adherence to corporate governance in the Nigerian Commercial banking
sector. The
outcome of this research is anticipated to contribute to existing body of
knowledge.In addition; the
study would highlight the regulatory and institutional factors which may
affect the adoption,
sustainable observation and practices of good corporate governance by banks in
Nigeria.
Since the corporate performance of banks and other
financial intermediaries is crucial for efficient resource allocation, at the
micro and macro levels, this study would show the importance for banks
themselves to put in place sound corporate governance. In fact, no one single
factor contributes more to institutional problems, capable of precipitating
crisis, than the lack of effective corporate governance (Lawal, 2009).
1.7
SCOPE OF THE STUDY
This
study investigated corporate governance and its impact on
performance commercial banks
in Nigeria. 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 (Achua, K,2007).
Financial sector stability, in turn has a profound externality on the economy
as a whole. To this end, the study basically covered five of
the commercial banks
operating in Nigeria till date that met the N25 billion capitalization
dead-line of 2005. The study will cover these banks’ activities during the post
consolidation period i.e. 2006- 2012.
