Market reactions to the disclosure of internal control weaknesses and to the characteristics of those weaknesses under section 302 of the Sarbanes Oxley Act of 2002

Abstract: We examine the stock price reaction to management's disclosure of internal control weaknesses under §302 of the Sarbanes Oxley Act and to the characteristics of these weaknesses, controlling for other material announcements in the event window. We find that some characteristics of the weaknesses-their severity, management's conclusion regarding the effectiveness of the controls, their auditability, and the vagueness of the disclosures-are informative. We also find that the information content of internal contr… Show more

“…We also contribute to research on the economic consequences of Section 404 internal control provisions including compliance with filing deadlines (Ettredge et al 2006) and disclosure of weaknesses in internal controls (Ogneva et al 2007;Beneish et al 2008;Hammersley et al 2008;Ashbaugh-Skaife et al 2009). With regard to the former, we find that late filing increased around initial compliance with Section 404.…”

“…Material weakness disclosures are associated with significantly negative stock returns (Beneish et al 2008;Hammersley, Myers, and Shakespeare 2008) ICDEF404_A is an indicator variable that equals one if the audit report identifies an ICOFR deficiency in the first fiscal year (after the IPO) the auditor opines on the effectiveness of ICOFR, and zero otherwise. The independent variable of interest, AU9550, is an indicator variable equal to one if the audit report included in the registration statement states that the auditor was not engaged to audit the effectiveness of ICOFR and, accordingly does not express an opinion thereon, and zero otherwise.…”

“…Regulatory intervention has been the driving force for the majority of the archival auditing studies (DeFond and Zhang, 2013). Several studies examine the impact of SOX on ERCs or other measures of perceived audit quality; for example, Hammersley et al (2008) report that stock returns were significantly less negative if a firm engaged a Big 4 auditor when firms disclosed internal control weaknesses during the period 2002-2005. However, more recent studies show no significant difference between Big 4 and non-Big 4 auditors or between Big 4 and second-tier auditors; for example, using the sample period -2006, Chang, Cheng, and Reichelt (2010 provide empirical evidence that firms switching from Big N auditors to non-Big N auditors experience non-negative stock returns. This finding suggests that market participants perceive no difference between the audit quality of Big N auditors and non-Big N auditors.…”
