Audit report information improvement and earnings management

Abstract

AbstractIncreasing the disclosure of key audit matters (KAMs) has been an important change in audit reports in recent years. After the implementation of this policy, what changes have taken place in the behaviour of auditors after the implementation of this policy? What impact has it had on the audit report? A series of problems deserve systematic analysis and empirical testing. This paper examines the relationship between the communication of KAMs and earnings management. We examined quasi‐natural experimental data shaped by new auditing standards issued by the Ministry of Finance of China on 23 December 2016. The new auditing standards have been implemented in phases for the listed companies. We find that (1) communicating KAMs in audit reports restrains the auditor's motivational reasoning behaviour by triggering rationality constraints and improves the auditor's professional scepticism, thus improving audit quality and significantly reducing the company's accrued earnings management level. (2) The influence of communicating KAMs on earnings management is more significant for sampled firms with high external financing dependence and low marketization, revealing its supplementary role in the existing corporate governance mechanism. The findings of this paper enrich existing research on KAMs and supplement important empirical evidence from the Chinese market for assessing the effects of audit reporting reforms worldwide.
