Does the mandatory disclosure of audit information affect analysts' information acquisition?

Abstract

This paper explores the effect of public information on analysts' information acquisition. By introducing the implementation of the Key Audit Matters (KAM) Disclosure Standards for China's firms cross-listed in Hong Kong in 2017, we present evidence that KAM disclosure reduces analysts' firm visits, which is an important channel of information acquisition. The effect is particularly pronounced for firms with audit partner rotation and low institutional ownership. KAM disclosure by industrial leaders has a spillover effect on analyst visits for peer firms. Disclosure also improves the frequency and quality of analysts' forecasts and firms' information environments, indicating that KAMs are informative and audit information is an important determinant of analysts' information acquisition. Our study reveals the real effect of KAM disclosure on analyst decisions, which may be of interest to regulators concerned with the mandatory disclosure of audit information and capital market efficiency.
