Internal audit: A comfort provider to the audit committee

This study, based upon four Belgian case studies, provides insights on (1) what drives the audit committee to look for the support of the internal audit function; and (2) what makes the internal audit function an expert at providing comfort to the audit committee [Pentland, B.T., 1993. Getting comfortable with the numbers: auditing and the micro-production of macro-order. Accounting, Organizations and Society 18 (7–8), 605–620; Carrington, T., Catasús, B., 2007. Auditing stories about discomfort: becoming comfortable with comfort theory. European Accounting Review 16 (1), 35–58]. We found that audit committees seek comfort, with respect to the control environment and internal controls, two areas in which they confront considerable discomfort. Besides the internal audit function's traditional assurance role, its involvement in improving internal controls provides a significant level of comfort to the audit committee. Internal auditors' unique knowledge about risk management and internal control, combined with appropriate inter-personal and behavioural skills, enables them to provide this comfort. Besides, their internal position, their familiarity with the company, and their position close to people across the company facilitate internal auditors being a major source of comfort for the audit committee. Formal audit reports and presentations, together with informal contacts, seem to be important symbols of comfort [Power, M., 1997. The Audit Society: Rituals of Verification. Oxford University Press, Oxford]. In addition, we found that the overall level of comfort to the audit committee can be enhanced via collaboration between internal and external auditing (the so-called ‘joint audit approach’).
