ABSTRACT
This study examined the effect of corporate governance on firm performance of some selected companies listed on the Nigerian Stock Exchange. The intent of the study was to determine whether corporate governance mechanisms- CEO duality, board size audit committee, and ownership concentration have an effect on firm performance surrogated by return on assets (ROA); return on equity (ROE), profit margin (PM). Data was sourced from annual report of selected companies. It provides empirical evidence for five (5) non-financial firms in Nigeria for a period of 2010 to 2014. In order to achieve this objective, data collected was analyzed using descriptive statistics and Jarque-Bera statistics to test for normality of variables; Pearson correlation matrix was used to check for multi co-linearity presence in a model and to explore the relationship between the explanatory variables and the dependent variable; The Ordinary Least Square (OLS) multiple regression is employed to test the hypotheses. The results reveal that; a) board size has a negative significant effect with return on asset (ROA), return on equity (ROE), earnings per share (EPS) and profit margin (PM); audit committee had a negative significant effect with return on equity (ROE), earnings per share (EPS) and profit margin (PM), but has a positive significant effect on return on asset (ROA); ownership concentration has a negative significant effect on return on asset (ROA), return on equity (ROE), earnings per share (EPS) and profit margin (PM). It is also observed that CEO duality has a negative significant effect on return on asset (ROA), return on equity (ROE), earnings per share (EPS) and profit margin (PM). The advocacy is for the Securities and Exchange Commission to take into cognizance industry specific effects before formulating codes of corporate governance that determine the characteristic of board structure. Proposition is also made for the Corporate Governance Committee of companies to endeavor to do a regular appraisal of their corporate governance compliance status so as to understand its effect on performance.
