The study examined the impact of integrated reporting on the performance of corporate organizations in Nigeria between 2009 and 2018. The major motivation for the study was the clarion call and the outcry by the public as regards environmental degradation due to firm activities. Unfortunately, such outcry were not really heard as information about the environment has not really been captured in the reports of firms which then makes them not accountable to their immediate environment. In the light of this necessity, the study which considered thirteen banks due to unavailability of data for the intended periods for the remaining five, used profit after tax as the dependent variable and also used IR index as a blend of financial and sustainability reporting, debt to equity ratio and total asset as independent variables. The study employed the classical Ordinary Least Square and Panel Co-integration techniques for analysis revealing that while IR has no significant impact on corporate performance in the short run, it has a significant relationship with firm performance in the long run. Hence, it was recommended that reporting authorities such as the FRCN should mandate firms to adopt the IR standard just like in South Africa as stipulated in their King’s Code of Governance in a bid to strengthen such long run relationship. Also, non-financial information that embraces long-term forecasting should be included in corporate reports in a bid to educate relevant entities about its long-term prospects and its ability to continue in the foreseeable future.

Fair Value Accounting and Corporate Reporting in Nigeria: A Logistics Regression Approach

Purpose This study investigates whether the external governance ecosystem enhances the corporate value of listed Nigerian banking institutions. Moving beyond the traditional board-centric approach, it examines the influence of regulatory oversight, external audit quality, and environmental governance as complementary external governance mechanisms operating through monitoring, credibility, and legitimacy channels. Methodology/Approach The study draws on agency, institutional, and stakeholder theories and employs a longitudinal panel design covering 11 listed Nigerian banking institutions over the period 2012-2025. Using 154 firm-year observations, Tobin’s Q serves as the measure of corporate value. The Prais-Winsten Panel-Corrected Standard Errors (PCSE) estimator is applied to address heteroskedasticity, serial correlation, and cross-sectional dependence. Firm size, leverage, and profitability are included as control variables. Findings The results reveal that regulatory oversight has a positive but statistically insignificant effect on corporate value, while external audit quality and environmental governance exhibit negative but insignificant effects. Among the control variables, firm size and leverage significantly reduce corporate value, whereas profitability has a positive but insignificant relationship with firm value. The findings suggest that external governance arrangements do not automatically generate market valuation benefits within emerging-market banking institutions. Originality/Value The study contributes to corporate governance literature by introducing an external governance ecosystem perspective that conceptualizes regulatory oversight, external audit quality, and environmental governance as interconnected governance institutions rather than isolated mechanisms. It also extends evidence from the underexplored context of Nigerian banking institutions and emerging markets. Practical Implications The findings highlight the importance of strengthening governance enforcement, disclosure credibility, and sustainability integration. Regulators, managers, and investors should focus on governance effectiveness rather than formal compliance, as external governance mechanisms appear to contribute more to transparency, accountability, and institutional legitimacy than to immediate market valuation gains.
