Sustainable performance, conditional conservatism and audit fees

Abstract

Purpose This paper aims to examine the effect of conditional conservatism on audit fees and whether the firm’s engagement in sustainable practices moderates the relationship between conditional conservatism and audit fees. Design/methodology/approach Using a sample of 3,767 firm-year observations from 14 European Union countries over the period of 2006–2019, the authors adopt the ordinary least square estimator to perform a panel data analysis of the effect of conditional conservatism on audit fees, and the moderating role of the environmental, social and governance (ESG) scores on the relationship between conditional conservatism and audit fees. Findings The authors find that conditional conservatism has a significant negative effect on audit fees, suggesting that auditors charge lower audit fees on more conservative clients. The authors also find that firms engaging in ESG actions, whether combined or individual, pay higher audit fees. More interestingly, the authors provide evidence that the negative effect of conditional conservatism on audit fees is mitigated only when ESG performance is considered in combination. This implies that firms exhibiting less commitment to ESG sustainability practices are prone to paying reduced audit fees when engaged in more conservative reporting. The findings remain robust after conducting a battery of tests. Practical implications The findings of this study have practical implications for several parties, including companies, auditors and regulators. This study emphasizes the potential benefit associated with using conservative accounting practices in terms of shaping downward the amount of audit fees. However, it also highlights the importance of considering the additional audit costs associated with higher ESG scores when making decisions about implementing sustainable practices. Originality/value Unlike prior studies that investigate the direct impact of sustainable practices on audit fees, the present work contributes to the literature on the benefits and costs of ESG by examining the moderating role of ESG performance in the association between audit fees and conditional conservatism. To the best of the authors’ knowledge, this study is the first to examine this relationship. Theoretically, the research integrates the theories of audit risk and agency to provide a more comprehensive understanding of the drivers of audit fees.
