The Effect of Internal Control Systems on Financial Reporting Quality in Selected Commercial Banks in Lagos State

This study examines the effect of internal control systems on financial reporting quality in selected commercial banks in Lagos State, South West Nigeria. The collapse of financial institutions in recent years has renewed concerns about the adequacy of internal controls and their capacity to ensure accurate and reliable financial disclosures. Despite regulatory reforms introduced by the Central Bank of Nigeria, questions persist about the effectiveness of existing control mechanisms at the branch and institutional levels. This study adopts a descriptive survey design, drawing on primary data collected through structured questionnaires administered to 120 accounting and audit staff across five commercial banks in Lagos. Secondary data were sourced from published annual reports spanning 2019 to 2023. The study evaluates four dimensions of internal control, namely control environment, risk assessment, control activities, and monitoring, using the Committee of Sponsoring Organizations framework. Data were analyzed using descriptive statistics and multiple regression analysis. Preliminary findings indicate a significant positive relationship between internal control effectiveness and the quality of financial reports produced by the sampled banks. Specifically, control activities and monitoring were found to have the strongest predictive influence on reporting accuracy. The study concludes that robust internal control systems are critical to maintaining the integrity of financial statements in Nigerian banking institutions. It recommends that bank management invest more in periodic control assessments and staff training to address identified gaps in compliance and oversight.
