Auditor Change Disclosures as Signals of Earnings Management and Risk

Auditor resignations are considered more negative signals than auditor dismissals, but firms’ self-reported distinction between the two may not offer a complete or reliable representation of the nature of the auditor change. 8-K regulations require the disclosure of the adjournment of an audit engagement even if a successor auditor has not yet been named. In compliance with this requirement, some firms file two 8-k’s related to the same auditor change. Exploiting these dual 8-K filings, we create a new measure of the nature of auditor changes and show that 1) both self-reported auditor resignations and dual 8-K filings are related to measures of earnings management and risk; and 2) auditor changes identified as both self-reported resignations and dual 8-K filings are associated with the most negative economic implications (as reflected by the likelihood of financial statement manipulation and bankruptcy risk). We suggest that dual 8-K filings and self-reported resignations are complementary negative signals each capturing unique dimensions of the underlying economic factors
