Does the severity of a client’s negative environmental, social and governance reputation affect audit effort and audit quality?

Abstract

In recent years, investors have begun to value companies’ reputations through their environmental, social, and governance (ESG) practices. ESG risk can affect business processes and controls and can heighten financial risk and threaten a firm’s survival. This study examines whether and how the severity of media coverage of a firm’s negative ESG issues (tainted ESG reputation) is associated with audit effort and audit quality. I find that auditors manage the higher expected engagement risk conveyed by tainted ESG reputation by applying higher audit effort. Next, I observe that the increased effort is associated with auditors likely detecting and requiring adjustments for material misstatements and that tainted ESG reputation is associated with fewer misstatements (i.e., reduces poor audit quality). The association between tainted ESG reputation and audit quality is driven primarily by increased audit report lag, not by increased audit fees. Further, I find that tainted ESG reputation is positively associated with audit effort and reduces poor audit quality for up to three years. The results also show that the audit effort and audit quality effect vary across the three components of ESG.
