Purpose The purpose of this paper is to analyze the perception held by attendees about the role and the effectiveness of their audit committees. Design/methodology/approach The investigation was conducted via a qualitative methodology through the content analysis of interviews conducted with 33 attendees of audit committee meetings of Tunisian listed companies. Findings The findings reveal that audit committees do not have the means to achieve the objectives that they have been given by the legal texts, which are likely to characterize their work as “ceremonial” or “symbolic.” This paper also found that the most significant effects of the audit committee chair’s role come through informal meetings and conversations. Practical implications The paper’s findings have policy implications for regulators. Findings from this research may allow regulators to assess whether the audit committee activities in Tunisian companies meet their expectations. Originality/value This paper tries to fill a gap in the extant literature and provides meaningful information on activities performed by audit committees and the extent to which they are perceived effective in the eyes of attendees of audit-committee meetings. This study is one of the few field investigations that have analyzed audit committees’ effectiveness in emerging markets through interviews with attendees involved in audit-committee processes.
