Income Smoothing and Its Impact on Shareholder Wealth Creation: Evidence from Firms in the Nigerian Financial Services Sector

Abstract

Understanding how income smoothing influences shareholder wealth is critical in the evolving dynamics of Nigeria’s financial sector. This study examines the relationship between income smoothing and shareholder wealth creation in Zenith Bank Plc, a leading financial institution in Nigeria, over the period 2002 to 2024. The aim is to evaluate how Return On Equity (ROE), Dividend Per Share (DPS), and Return On Assets (ROA) Affect Earnings Per Share (EPS), a key proxy for shareholder wealth. An ex-post facto research design was employed, using secondary data sourced from Zenith Bank’s financial reports. Analytical techniques included trend analysis, SWOT, PESTEL, and regression analysis, carried out with the EViews software. The regression results revealed that ROA and ROE had positive coefficients, while DPS had a negative coefficient; however, none of the independent variables were statistically significant (ROA: p=0.2852, ROE: p = 0.9225, DPS: p = 0.5613). The overall model was not significant (p = 0.149), indicating that income smoothing did not have a statistically confirmed impact on shareholder wealth during the period under review. The study is limited by its focus on a single institution, which may affect the generalizability of the findings. Future research should consider a comparative analysis across multiple banks or financial institutions, both locally and internationally. In conclusion, while income smoothing did not significantly influence shareholder wealth statistically, the strategic management of income trends, asset utilization, and dividend policy remains essential for long-term value creation in the banking sector.
