Abstract

This study examines the influence of board and audit committee characteristics on integrated reporting disclosure among publicly listed firms in five Association of Southeast Asian Nations (ASEAN) countries during 2020–2024. The study is motivated by the growing importance of integrated reporting in voluntary disclosure environments, where internal governance mechanisms may play a more decisive role in shaping reporting practices (M. Ali et al., 2024). Using purposive sampling, the study analyzes 142 firm-year observations from 46 firms and measures integrated reporting disclosure through content analysis based on the Pistoni et al. (2018) Integrated Reporting Scoreboard. The data are analyzed using panel regression with firm fixed effects and clustered standard errors, supported by alternative model specifications for robustness. The findings show that board independence and audit committee independence have positive and significant effects on integrated reporting disclosure, indicating that independence-based governance mechanisms are more effective in promoting transparency and accountability in integrated reporting. In contrast, board size, board diversity, and board activity do not significantly affect integrated reporting disclosure. The study contributes to the governance-disclosure literature by showing that, in the ASEAN context where integrated reporting remains largely voluntary, independence-related governance mechanisms appear more influential than structural board characteristics in encouraging integrated reporting disclosure.
