Abstract: The revelation of accounting fraud by the Olympus Corporation gave rise to shareholder allegations of audit failure against Olympus’ auditors—Ernst & Young ShinNihon LLC and KPMG AZSA LLC—in 2011. In this study, we investigate whether the auditors’ affiliation with Olympus contributes to divergent perceptions of audit quality in the event of news announcements affecting the reputation of Olympus’ auditors. First, we use a nonparametric generalized rank event study methodology on 918 sample firms from the First Section of the Tokyo Stock Exchange (TSE) to observe Japanese investors’ perceptions of auditor reputation as proxied by abnormal returns. Second, we perform a multivariate linear regression on firms’ abnormal returns after controlling for firm-specific variables. We find that Japanese investors do not respond to negative or neutral reputational information arising from news announcements concerning Olympus’ auditors for firms affiliated and not affiliated with those auditors. In the absence of legal penalties imposed on Olympus’ auditors, we argue that Japanese investors consider the Olympus fraud case as an expected occurrence of audit failure due to a lack of evidence suggesting systematic audit failure on the part of Olympus’ auditors and an expectation of lower audit quality in the Japanese capital market. As a result, Japanese investors do not consider news announcements affecting the Olympus auditors’ reputation as sufficient evidence to change their prior expectation regarding the reputations of the audit firms affiliated with the Olympus fraud case.
