审计师声誉损失与审计保险价值

Reputation loss of auditors and the insurance value provided by the audits

本文通过万福生科财务舞弊案,用事件研究法计算了窗口期内万福生科主审事务所——中磊会计师事务所的其他客户的累计异常报酬率,旨在发现其中由审计失败所形成的审计师声誉损失是否导致审计保险价值减损这一经济后果。并通过统计涉案事务所的核心人力资源流失和客户流失的情况,以揭示审计师声誉损失所带来的负面影响。结果表明,审计师声誉损失造成事务所的核心人力资源大规模流失、客户迅速流失,并引发审计的保险价值显著下降。此外,审计师声誉损失还会带来审计的信息价值减损。
