Abstract
This study examined the effect of audit quality determinants on financial statement accuracy of listed oil and gas firms in Nigeria. The study focused on audit tenure, audit committee size, audit committee meeting frequency, and audit firm size, while financial statement accuracy was proxied by return on assets (ROA). The research adopted an ex- post facto design using secondary data extracted from the annual reports of eleven listed oil and gas firms on the Nigerian Exchange Group (NGX) covering a ten-year period from 2015 to 2024. The data were analyzed using descriptive statistics, correlation analysis, and panel regression techniques conducted in SPSS and EViews 13. The diagnostic tests, including the Jarque-Bera normality test, Variance Inflation Factor (VIF), Breusch-Pagan test, and Durbin-Watson statistic, confirmed the absence of multicollinearity, eroskedasticity, and autocorrelation, indicating the reliability of the regression output. The findings revealed that audit tenure has a negative but insignificant efect on financial statement accuracy, while audit committee size, committee meeting frequency, and audit firm size exhibited positive but insignificant effects on financial statement accuracy. The overall regression model was not statistically significant, suggesting that the selected audit quality attributes do not meaningfully explain variations in the financial accuracy of the sampled firms. It recommends that firms and regulators shift focus from structural audit attributes toward strengthening auditor independence, audit committee expertise, and enforcement of corporate governance practices.
