Effect of Board Size and Ceo Tenure on Performance of Quoted Insurance Firms in Nigeria

The Nigerian insurance industry still seems to be performing below expectation despite all efforts of owners, managers and government regulation. This study examined the effect of board size and CEO Tenure (being corporate governance mechanisms) on performance (Tobin Q) of quoted insurance companies in Nigeria from 2008-2019. The research design used in the study is the exploratory research design. The population for this study is all twenty -three (23) insurance firms listed on the Nigerian Stock Exchange (NSE) as at December, 2019. Secondary data was collected and analysed for this study, sourced from Central Bank of Nigeria’s (CBN) Statistical Bulletin, Nigerian Stock Exchange (NSE) Fact book and the listed firm’s published financial statements for the per iod of 2008 -2019. Panel regression technique was used to analyse the data. The study found out that board size has no significant effect on the performance of quoted insurance firms in Nigeria as measured by Tobin’s Q while CEO Tenure had a positive and si gnificant effect. The study recommends that since board size has been insignificant to performance but shows a positive effect, then the ownership of quoted insurance firms in Nigeria should continue to improve on their board size practices so that it may become significant while they continue with their CEO tenure practices since it is already positive and significant to performance.
