The Impact of Expanded Audit Reports in Hong Kong and China
Key audit matters show limited effect on market reactions and audit quality.
1Transition to Expanded Audit Reports
Hong Kong adopted expanded audit reports in 2016, followed by China in 2017, aligning with IAASB standards. These reports include key audit matters (KAMs), detailing significant risks in the audit process. The goal was to enhance investor transparency and audit quality. However, differences in investor protection and legal enforcement between the two regions remain notable.
2Market Reactions and Audit Quality
The study found no compelling evidence that expanded audit reports influenced market reactions or audit quality. Analyses using company fixed effects showed KAMs did not meet investors' demand for incremental information. This highlights a gap between regulatory intent and implementation, suggesting KAMs may not be as effective as intended.
3Impact of KAM Characteristics
A higher number of KAMs and novel or transaction-specific KAMs were associated with stronger pricing of fundamentals, indicating investors perceived these financial statements as better vetted. However, these KAMs also correlated with lower profitability persistence, reflecting higher company risk and volatility.
4Role of Industry-Common KAMs
Industry-common KAMs appeared less relevant for valuation, as investors tended to discount routine disclosures. Yet, these KAMs were linked to more persistent performance, likely due to stable industry conditions. This underscores the importance of KAM content in shaping investor perceptions.
5Investor Perception and Risk
Novel KAMs signaled company risk and volatility, influencing investor decisions. While investors valued these disclosures, they also associated them with reduced profitability persistence. This duality suggests KAMs can have nuanced effects on market behavior.
6Limitations of Regulatory Framework
The study concluded that mandating expanded audit reports alone offers limited value. However, better-tailored KAM disclosures could still signal firm fundamentals and future performance. Regulators may need to refine KAM formats to enhance their usefulness.
7Implementation Challenges
Audit reports in Hong Kong and China fell short of fully addressing investor needs. Differences in legal systems and investor protection levels limited KAM effectiveness, highlighting the need for localized adaptations of global audit standards.
8Recommendations for the Future
The research advocates for more specific and informative KAMs. Disclosures that better reflect company risks and industry dynamics could offer greater value to investors. Regulators should review KAM formats and provide guidance to improve audit quality.
