Determinants and consequences of voluntary switches to Chinese auditors in Hong Kong

Abstract

Hong Kong market regulators have permitted 12 large Chinese accounting firms to audit the financial statements of Chinese firms that cross list in Hong Kong (i.e., H-share firms) since 2010. This paper examines the characteristics of H-share firms that voluntarily replaced their Hong Kong (HK) auditors with Chinese auditors, and the market reaction to auditor switches following this policy. We find that 38 out of 147 H-share firms voluntarily switched to Chinese auditors during 2011–2013. Switching firms are larger in size and are less likely to use Big4; they also have less need for external financing, a longer cross listing history, and a lower percentage of foreign revenue. We also find that investors negatively react to the auditor switches from HK non-Big4 to China non-Big4, but do not react to the auditor switches from HK Big4 to China Big4. This suggests that investors perceived lower audit quality for China non-Big4.
