We examine the association between auditor choice and the accruals patterns of Chinese listed firms that cross-list in Hong Kong.Our evidence suggests that the clients of Big 4 auditors report lower unsigned discretionary accruals relative to the clients of non-Big 4 auditors.Further,we find that cross-listed firms with non-Big 4 auditors are more likely to understate their earnings and experience larger reversals of accruals in the future than cross-listed firms with Big 4 auditors.These findings suggest that Big 4 auditors play a meaningful role in improving earnings quality for cross-listed firms,which helps to explain why crosslisted firms have higher earnings quality than their domestic counterparts,as documented in the previous literature.
