Auditor litigation: Evidence that revenue restatements are determinative

This study extends the Palmrose and Scholz (2004) general litigation and general restatements study by focusing on auditor litigation and revenue restatements. We investigate all potential accounting issues, individually, instead of by their group method, with regard to auditor litigation. The impact of the individual accounting issues implicated in restatements is of concern to auditors and audit standard setters in gauging auditor litigation risk and audit risk. It also is important for financial analysis and securities valuation because investors' losses are greater, and recovery of losses on a percentage basis is lower, when the auditor is a defendant, and especially when the auditor has a more severe, negative litigation experience (Commolli et al., 2012). We examine financial reporting lawsuits filed from 2001 to 2008 and find that revenue restatements—far more than any other kind of restatements—are associated with auditors being named defendants and also auditors experiencing a more severe, negative outcome in the litigation.
