Do auditors care about real earnings management in their audit fee decisions?

This study investigates whether auditors incorporate the implications of potential litigation risk arising from their client firms' using real earnings management (REM) to manage earnings. Using a large sample of US firms, we find that REM is positively related to audit fees and that this relation is incremental over and beyond the effects of accrual-based earnings management and other control variables. We also find that the positive relation between REM and audit fees is stronger for firms with sophisticated investors or higher stock price sensitivity to accounting earnings. Finally, we find that this positive relation is more pronounced for firms with financial constraints where REM is more likely to stem from managerial opportunism and is perceived as riskier by auditors. These findings are robust to endogeneity controls and various sensitivity tests.
