Performance matched discretionary accrual measures

Audit committee, board of director characteristics, and earnings management

This study examines the relation between audit quality and earnings management. Consistent with prior research, we treat audit quality as a dichotomous variable and assume that Big Six auditors are of higher quality than non-Big Six auditors. Earnings management is captured by discretionary accruals that are estimated using a cross-sectional version of the Jones 1991 model. Prior literature suggests that auditors are more likely to object to management's accounting choices that increase earnings (as opposed to decrease earnings) and that auditors are more likely to be sued when they are associated with financial statements that overstate earnings (as compared to understate earnings). Therefore, we hypothesize that clients of non-Big Six auditors report discretionary accruals that increase income relatively more than the discretionary accruals reported by clients of Big Six auditors. This hypothesis is supported by evidence from a sample of 10,379 Big Six and 2,179 non-Big Six firm years. Specifically, clients of non-Big Six auditors report discretionary accruals that are, on average, 1.5-2.1 percent of total assets higher than the discretionary accruals reported by clients of Big Six auditors. Also, consistent with earnings management, we find that the mean and median of the absolute value of discretionary accruals are greater for firms with non-Big Six auditors. This result also indicates that lower audit quality is associated with more “accounting flexibility”.

The market pricing of accruals quality

The pricing of discretionary accruals

We find no evidence that non-audit service fees impair auditor independence, where independence is surrogated by auditors' propensity to issue going concern audit opinions. We do find, however, that auditors are more likely to issue going concern opinions to clients paying higher audit fees, suggesting that auditors behave with relatively greater independence towards these clients. Our findings are consistent with Reynolds and Francis (2001) and suggest that market-based incentives, such as loss of reputation and litigation costs, dominate the benefits auditors are likely to receive from compromising their independence to retain clients that pay larger fees. Overall, our findings indicate that recent SEC regulations based on concerns that non-audit services impair auditor independence, are unfounded.

Do Non-audit Service Fees Impair Auditor Independence? Evidence from Going-concern Audit Opinions

We find no significant association between non–audit service fees and impaired auditor independence, where auditor independence is surrogated by auditors’ propensity to issue going concern audit opinions. We also find no association between going concern opinions and either total fees or audit fees. In addition, our findings are robust to controlling for unexpected fees, to controlling for endogeneity among our variables, and to several alternative research design specifications. Our results are consistent with market–based incentives, such as loss of reputation and litigation costs, dominating the expected benefits from compromising auditor independence.
