Determinants of audit fees for quoted UK companies

This study reports further evidence as to the determinants of the audit fees paid by quoted companies in the UK. It outlines a framework based on the findings from semi-structured interviews with partners in four large audit firms and the results of previous research, and tests this framework by means of multivariate analysis using 1987 data for a large sample of quoted UK companies. A model explaining 87 per cent of the variation in audit fees is constructed. The principal explanatory variables are found to be auditee size, return on shareholders equity, the number of subsidiaries, the lag between the year end and the date of the audit report, the size of the auditor, a measure of auditee diversification, the ownership structure of the auditee, and whether the auditor was based in London, with the last three being new variables introduced in this study
