Do key audit matters matter? Correspondence between auditor and management disclosures and the role of audit committees

This study examines whether there is a correspondence between auditor disclosures of key audit matters (KAMs) and management disclosures of significant accounting policies and estimates, following the introduction of the International Standard on Auditing (ISA) 701. In addition, we investigate how audit committees moderate the relationship. We employ a sample of Swedish listed firms (2016–2018), using measures that capture the extent and quality of management disclosures and how they relate to auditor KAM disclosures, including the number of accounting items disclosed, total number of words, and number of unique KAM-related words (via a “bag-of-word” technique). We find a positive correspondence between auditor and management disclosures, and the correlation is greater in firms with an audit committee. Additional analyses provide evidence that management disclosure quality increases after the introduction of ISA 701, but the positive effect is mostly found in firms with a separate audit committee on the board. The results are robust to alternative measures for disclosures and using a matched sample design. Our findings suggest that policymakers should consider the interplay between audit standards and audit committees.
