Abstract

In response to increasing public demand for more audit information, regulators worldwide have mandated expanded audit reports that disclose Key Audit Matters (KAMs).  We analyze whether investors pay attention to KAMs exploiting novel data from the Investor Interaction Platform (IIP) in China, where investors frequently communicate with firms by asking questions.  We show that investors are more likely to raise KAM-related questions on the IIP following KAM disclosures.  Our results also indicate that this effect is more salient when there are more retail shareholdings, when the KAM is uncommon in the industry, and when the firm’s information environment is more opaque.  In terms of trading behavior, we find that the increase in KAM-related questions leads to higher trading volumes.  Our findings suggest that investors attend to KAMs and that their processing of KAM information translates into trading activities.
