Abstract
Restating 10-Ks has become an increasingly common phenomenon in financial reporting. Restatements clearly signal that the firm's prior financial statements were not credible and were of relatively lower "quality". In this study, we examine the effect of restatements on investors' and dealers' perceptions of the firm. First, we examine the market returns and the bid-ask spread effects at the announcement of the accounting problem that leads to restatement. We find negative market returns for accounting problem announcements, and we find that the negative reaction is most pronounced for firms with revenue recognition issues. We also find an increase in spreads surrounding the announcement of revenue recognition problems. Second we examine returns and spreads from the announcement of the restatement to the filing of the restated financial statements. We find a significant negative market reaction and a larger negative reaction for firms with revenue recognition problems. We find no change in spreads from before the announcement of the accounting problem to after the restatement is filed. Finally, we examine the effect of the restatement on earnings response coefficients, and find that the market reacts less to earnings after a restatement than to earnings prior to a restatement. In general, these results indicate that investors and dealers react negatively to restatements and are more concerned with revenue recognition problems than with other financial reporting errors.
