ABSTRACT
The objective of
this study is to empirically investigate the relationship between corporate governance
(measured by Board Size, Ownership Concentration and CEO Duality) and
profitability (measured by Return on Asset and Return on Equity) of selected
Nigerian manufacturing companies.
The study
adopted survey research design. Random sampling was used to select 10 companies
out of a total population of 45 manufacturing companies listed on the Nigerian
Stock Exchange, for a time period of 2006 to 2015. Secondary data (financial
and non-financial) were collected from the annual reports and accounts of the
selected listed manufacturing companies. Pooled OLS regression, Fixed Effect
and Random Effect analysis and descriptive statistics were used in analyzing
the data. F-stat was used to test the hypothesis.
The results of
the study show that Board size had a positive relationship but not significant
with performance of the sampled manufacturing companies. Also, it was found
that CEO duality had a negative but significant relationship with the
performance of the sampled manufacturing companies, while Ownership
concentration had a significant positive relationship with performance of the
sampled manufacturing companies.
In conclusion, the study revealed that the
performance indicator (ROA) and (ROE) related with each component of the
Corporate Governance Index in a peculiar manner. It is therefore suggested that reform efforts
should be directed towards improving the corporate governance of listed
Nigerian manufacturing companies, especially emphasis should be devoted to
ownership concentration.

INTRODUCTION
- Background
to the Study
The issue of corporate governance
has brought about research interests with respect to principal-agent
relationship currently existing in publicly quoted companies. This is in
corroboration with Claessens and Fan (2002) who opined that corporate
governance has received much attention in recent years due to failure of some
firms in Asia.
Corporate governance reform has emerged as a critical business issue, thrust on the world stage by a number of high profile corporate failures (Strandberg, 2005). The famous corporate accounting scandals of Enron Corporation, World Com, Tyco, and Parmalat have led to contemporary discussion on the best mechanisms for protecting stakeholder’s interest and ensuring shareholders wealth maximization. Also, in Nigeria the emphasis on the need for corporate governance reform sprung up with the incidence of fraudulent financial reporting as reported in the case of Cadbury Nigeria Plc.In Nigeria, the growing incidence of corporate fraud has meant that investors’ confidence in the capital market has declined due to the current down turn in the market which is been blamed on the fraud at the Nigerian Stock Exchange (NSE) and investors in Cadbury (Nig)plc also lost heavily as the share price of the company took a downward turn. Organizations have monitoring mechanisms aimed at ensuring good corporate governance and minimization of corporate fraud. The primary objective of corporate governance is to try to align managerial incentives with that of stakeholders so that managers work in the best interest of the stakeholders (Nworji, Adebayo, & David, 2011).
