Abstract: We examine whether the mandate for auditors to report key audit matters (KAMs) affects firm-specific stock price crash risk in China. Auditors in China are required to issue an expanded audit report that contains KAMs for AH-share firms, effective on January 1, 2017 (applicable to the financial year 2016), and for A-share firms, effective on January 1, 2018 (applicable to the financial year 2017). Applying a staggered difference-in-differences (D-i-D) design on a sample of 18,751 observations for financial years 2012–2019, we find that auditor reporting of KAMs is not significantly associated with stock price crash risk. The mechanism tests show that the disclosure of KAMs does not reduce information opaqueness and managerial opportunistic behaviors. Furthermore, our findings are not sensitive, but are robust to firms' corporate governance, product market competition, ownership structure, and auditor size. Overall, our study informs regulators, investors, auditors, and other stakeholders interested in the economic consequences of mandating KAM disclosures.
