CORPORATE GOVERNANCE AND ORGANIZATION PERFORMANCE(A Case Study of Nigeria Insurance companies)

Abstract

This study investigates the relationship between corporate governance mechanisms and the financial performance of listed insurance companies in Nigeria. In recent years, weak governance practices have been associated with declining investor confidence, financial scandals, and poor firm performance. Given the critical role of insurance firms in Nigeria’s financial system, strengthening governance mechanisms has become imperative for enhancing transparency, accountability, and sustainable growth. The study specifically examined three corporate governance variables board size, board composition, and board independence and their impact on three financial performance indicators: earnings per share (EPS), price earnings ratio (P/E), and dividend per share (DPS). An ex-post facto research design was employed, and panel data were collected from the annual reports of sixteen (16) insurance companies listed on the Nigerian Exchange (NGX) over an eleven-year period (2011–2021). The data were analyzed using descriptive statistics, panel regression analysis (fixed and random effects), and post-estimation diagnostics. The findings revealed mixed relationships between corporate governance mechanisms and financial performance. Board size demonstrated both positive and negative effects depending on the chosen performance metric, suggesting that an optimal board size is essential for efficiency. Board composition, measured as the proportion of non-executive directors, did not consistently improve firm performance, indicating that independence in numbers alone does not guarantee effective oversight. However, board independence was found to have a positive and significant effect on dividend per share (DPS), implying that independent directors enhance accountability and ensure that shareholders’ interests are better protected. The study concludes that corporate governance significantly influences the financial performance of Nigerian insurance companies, although the impact varies across governance variables and financial indicators. It recommends that insurance firms maintain moderate board sizes, strengthen board composition through diversity and expertise rather than numbers alone, and reinforce board independence in line with regulatory standards. Regulators such as NAICOM should intensify enforcement of governance codes, while firms should invest in capacity-building for board members. The study is limited by its reliance on secondary data and the focus on a narrow set of governance and performance variables. Future research is encouraged to include broader governance indicators (such as CEO duality, ownership structure, and audit committee effectiveness), expand the scope to unlisted insurance companies and other financial institutions, and adopt a cross-country comparative approach.
