This paper aims to clarify the relationship between key audit matters (KAMs) disclosure and corporate financialization. The findings reveal that key audit matters (KAMs) disclosure can provide incremental information value, thereby impeding corporate financialization in China. Moreover, this effect is more pronounced in the samples with low media attention, low shareholding of institutional investors, and non-state-owned enterprises. Further research indicates that reducing managerial myopia and easing financing constraints serve as key channels through which key audit matters (KAMs) disclosure affects corporate financialization. This study provides empirical evidence on efficiently preventing excessive financialization of enterprises, as well as some insights for mitigating systemic financial risks from the key audit matters (KAMs) disclosure perspective.

In contrast to previous literature, our study not only examines the communicative value of Key Audit Matters (KAMs) through the capital market reaction to KAMs but also analyses the content and reporting format of KAMs, which vary based on the intrinsic risk of business activity. Using a sample of Chinese firms from 2017 to 2020, we find that more M&A-related KAMs are reported and they are disclosed through less boilerplate language when M&As are accompanied with the Performance Commitment contracts (PCs), an indicator as high possibility of overpayment during M&As thus inducing the high risk of the goodwill impairment and high litigation risk. Additionally, we find that the negative impact of PCs on boilerplate language is amplified when the benchmark in PCs is precisely achieved or when the firm has been sued in recent years. In other words, the disclosure of M&A-related KAMs is more tailored to the client firm when auditors observe a high risk for accountability. Consequently, capital market participants, as well as other recipients of auditing reports, such as regulators and analysts, perceive non-boilerplate M&A-related KAMs as informative for their decision-making process.
