Comment Letters and Reporting Quality: Evidence from Financial Restatements*

This study investigates the impact of comment letter reviews on reporting quality in terms of financial restatements, using comment letters from the Chinese market between 2013 and 2020. The baseline results indicate that although receiving a comment letter increases the next year's (year t + 1) restatements, it reduces later years' (year t + 2 onwards) restatements. Moreover, this effect is more pronounced among firms with lower external auditor quality, poorer information transparency, and those located in less marketized provinces. The mechanism analyses show that comment letter reviews improve financial reporting quality because of deterrent effects in the form of increased litigation risk.
