Effects Of Board Nationality And Ethnic Diversity On The Financial Performance Of Listed Firms In Nigeria

 ABSTRACT

This study examined the effect of board nationality and ethnic diversity on firms’ performance in the Nigeria stock exchange. With the aim of investigating the level of influence ethnic diversity and board nationality would affect firm performance in terms of profitability and growth in a developing economy, the study made use of ROA, ROE and Tobin’s Q for financial measures. The study analysed date from 60 non-financial firms with periodic observations from 2012-2015 using the ordinary least squares regression method. Yemeni formula was used to calculate the sample size out of the remainder 119 listed non-financial after 57 listed firms from the financial sector were removed. The total sample size was further streamlined to 60 based on a common reporting period (January 1st to December 31st) to ensure consistency. The Findings indicate that ethnic diversity and board nationality has no significant influence on the performance level of firms in both profitability (ROA and ROE) and growth (Tobin’s Q). Findings also reveal that the average board size of the listed non financial firms in Nigeria meets the countries corporate governance requirement of nine (9) members and the average board has a combination of at least two of the three ethnic groups in Nigeria. The board composition of sampled firms still reveals the presence of family members in same board which is against the central board composition code of corporate governance. This study encourages a diverse board since there is no significant effect on financial based performance; it is still advisable to be diverse except cost outweighs benefits. Diversity always tends to have effects on the way the board members make a decision, or strategic moves. It sets a control, brings innovation and could also slow down the rate of decision making.
