Debt contract strictness and auditor specialization

The conflicts of interest among managers, shareholders and creditors resulting in agency costs, can be mitigated by restricting managers’ adverse behavior, through financial covenants to better align the various stakeholder interests. Thus, debt contract strictness represents an important aspect of agency costs between creditors, shareholders, and management that is not always captured by interest rates. The contract setting provides a unique opportunity to investigate how creditors may rely on auditors to alleviate information uncertainty stemming from reliance on management's financial reporting and thus alleviate the creditor's potential loss of invested capital. After controlling for borrower risks, loan characteristics, and audit factors, we show that auditor industry specialization is significantly associated with a reduction in the strictness of debt contracts, consistent with creditors viewing certain industry expert auditors as effective monitors against financial reporting manipulation aimed at the avoidance of debt covenant triggers that protect creditors against potential loss. Further, we find that the association between loan strictness and auditor specialization is attenuated by stronger corporate governance systems, external monitors, and prior lender relationships.     

Do seasoned industry specialists provide higher audit quality? A re-examination

The purpose of this paper is to re-examine the recent findings in Gaver and Utke (2019) (GU) who find that seasoned industry specialist auditors provide higher audit quality. We first illustrate how the magnitude of residuals from the accruals model can vary significantly by industry, thus highlighting the importance of including industry fixed effects when the dependent variable is discretionary accruals. We next replicate GU’s findings. We first attempt to replicate prior literature after including industry fixed effects in the audit quality (discretionary accruals) models. This is an important control, as the relevant benchmark for a firm with an industry specialist auditor is a peer firm in the same industry with a non-specialist auditor. We find that after including industry fixed effects, there is no association between seasoned industry specialist auditors and discretionary accruals. We also find that the association between industry specialization and discretionary accruals is very sensitive to the way in which the researcher calculates specialization. Our findings are informative for shareholders of public companies who vote on auditor ratification.     

Audit fees around dismissals and resignations: Additional evidence

This paper offers new findings about how audit fees vary around auditor dismissals and resignations. For dismissals, we find evidence of lower than normal fees before and after an auditor change, consistent with the view that both incumbent and successor auditors adjust fees downward to retain the client. Our evidence also shows that incumbent and successor auditors charge unusually high fees before and after a resignation. We interpret the higher than normal incumbent fees as an indication that resignation companies reflect unusual levels of audit effort or risk, which the incumbent auditor captures as additional fees. Eventually, however, the additional fees are insufficient, inducing the incumbent to resign. A fee premium by the successor auditor after resignation also supports this view.

Using machine learning to predict auditor switches: How the likelihood of switching affects audit quality among non-switching clients

In this paper, we utilize machine learning techniques to identify the likelihood that a company switches auditors and examine whether increased likelihood of switching is associated with audit quality. Building on research that finds a deterioration in audit quality associated with clients that engage in audit opinion shopping, we predict and find lower audit quality among companies that are more likely to switch auditors but remain with their incumbent auditor. Specifically, we find that companies more likely to switch auditors have a higher likelihood of misstatement and larger abnormal accruals. These results are consistent with auditors sacrificing audit quality to retain clients that might otherwise switch. Our findings are especially concerning because there is no public signal of this behavior, such as an auditor switch. Our methodology is designed such that it could be implemented by investors, audit firms and regulators to identify companies with a higher probability of switching auditors and preemptively address the deterioration in audit quality.     

Perceived auditor independence and audit firm fees

Regulations requiring the disclosure of fees paid to an auditor for audit and non-audit services (NAS) respond to concerns that such payments are potentially detrimental to auditors' actual or perceived independence. Although empirical studies have failed to produce unequivocal evidence of detrimental effects on auditor independence, the actions of regulators, audit firms and companies are consistent with the belief that economic bonding generated by fees can impair perceived levels of auditor independence.

Using a sample of UK companies over a six year period to March 2006, we study perceived impairment of auditor independence by examining the relationship between levels of total relative fees (combined audit and NAS fees payable by a company to its auditor as a proportion of the audit firm's UK income) and market value. This paper's methodological innovation is its use of a valuation framework in this setting. A further contribution lies in dropping the assumption of linearity found in most prior empirical studies. We provide evidence that shareholders perceive a threat to auditor independence only at high total relative fee levels. At lower levels, total relative fees are positively related to company value. These results suggest that disclosure of NAS and audit fees are of relevance to investors, as is information about auditor income. Our results support the view that regulation by reference to the threshold at which total relative fees are perceived negatively is more consistent with investor preferences than prohibition of the supply of NAS by auditors to their audit clients.     

Does Ethical Culture in Audit Firms Support Auditor Objectivity?

The suggested cause of constrained auditor objectivity has been centred on auditors' financial incentives and long audit tenure. Recent research has challenged those assumptions and questioned the effectiveness of auditor rotation to counteract short-tenure threats to auditor objectivity. Audit firms and regulators need to adopt methods for enhancing auditor objectivity that are effective in various auditor–client relationships. This study examines whether audit firm ethical culture is positively related to auditor objectivity. Based on the responses of 281 practising auditors, the findings indicate that auditors are more likely to make objective judgments in ethical cultures characterized by the rewarding of ethical behaviour and punishment of unethical behaviour, prevalence of ethical norms, visible ethical leadership, and low emphasis on obedience to authority. In conclusion, evidence indicates that auditors in audit firms with a strong ethical culture are more likely to maintain auditor objectivity than are auditors in less supportive cultures. This suggests that audit firms should promote a strong ethical culture to reduce the risk of constrained auditor judgment.     

The Small Company Audit Qualification: A Preliminary Investigation

In recent years there has been much debate in the UK regarding the value and feasibility of the small company audit. The lack of formal internal control systems and the application of universal auditing standards has given rise to the use of a special ‘Small Company (Example 6) Audit Qualification’. However, doubts concerning the uniformity of practice between auditors has created difficulties for users in interpreting its meaning. This paper examines the extent to which a number of financial, organisational and auditor variables are able to explain the receipt of a ‘Small Company Audit Qualification’. The main empirical findings, using multivariate logistic analysis on a sample of 540 small company reports, are that companies audited by large audit practices, companies which had a prior year qualification, a secured loan, declining earnings, large audit lags and few non-director shareholders were more likely to receive an audit qualification than other companies.     

Auditor specialization, perceived audit quality, and audit fees in the local government audit market

Prior governmental research implies a positive relation between auditor specialization and audit quality, but the effect of specialization on audit fees is mixed. However, no single governmental study investigates the effect of auditor specialization on both audit quality and audit fees. Also, prior studies focus on either large- or small audit firms and often employ indirect proxies for audit quality. We study the effects of auditor specialization on perceived audit quality and audit fees. Our data represent both Big 5 and smaller audit firms and include three market-based measures of specialization. We survey 241 Florida local government finance directors and find that specialization is positively associated with perceived audit quality but not with audit fees. We also find that Big 5 auditors, often used as a proxy for higher audit quality in prior research, are not uniformly associated with increased perceived audit quality but consistently charge higher audit fees. Our results confirm a relation between measures of audit firm specialization and audit quality and raise questions regarding audit firm size and audit quality in the municipal sector. Our findings suggest that engaging specialized auditors may be good policy for many local governments.     

Auditor size and audit quality

Regulators and small audit firms allege that audit firm size does not affect audit quality and therefore should be irrelevant in the selection of an auditor. Contrary to this view, the current paper argues that audit quality is not independent of audit firm size, even when auditors initially possesses identical technological capabilities. In particular, when incumbent auditors earn client-specific quasi-rents, auditors with a greater number of clients have ‘more to lose’ by failing to report a discovered breach in a particular client's records. This collateral aspect increases the audit quality supplied by larger audit firms. The implications for some recent recommendations of the AICPA Special Committee on Small and Medium Sized Firms are developed.     

The influence of auditor narcissism and moral disengagement on risk assessments of a narcissistic client CFO

Global capital markets rely heavily on independent and skeptical auditors as gatekeepers to provide assurance that corporate financial reports are free of material fraud. The rise of narcissism among the ranks of both client and audit professionals challenge this gatekeeper function. In addition, auditor moral disengagement may undermine auditor skepticism, further eroding public confidence in the integrity of financial reporting and the audit process. We conduct a quasi-experiment with 118 auditors from three international audit firms. In a simulated interview with a client CFO, we examine whether auditors underestimate risks of fraudulent financial statements due to the interactive effects of (1) client narcissism (manipulated verbally and nonverbally) and (2) auditor narcissism. We also examine the influence of auditor moral disengagement on client risk assessments. Results indicate that CFO verbal and nonverbal narcissism significantly influenced auditors’ assessment of management-related client risk. Moreover, auditor narcissism was found to interactively influence client risk inferences such that auditors higher in narcissism exhibited narcissistic tolerance (lower risk assessments) when the hypothetical CFO displayed high verbal narcissism. Auditor moral disengagement was negatively associated with client risk assessments. We discuss the implication of these findings on future audit judgment research, audit firm policy and training on maintaining auditor skepticism, and the audit oversight role of standard-setters.     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.     

Non-audit services, auditor quality and the value relevance of earnings

This paper tests the hypothesis that there is an inverse relation between non‐audit services (NAS) provided by a firm auditor and the value relevance of earnings (measured as the earnings response coefficient) and that this relation is weaker for firms with Big 6 auditors. The hypothesis is based on anecdotal evidence and previous research that suggests that the provision of NAS by the external auditor is likely to adversely affect investors’ perceptions of the credibility of financial reports, and that Big 6 auditors, because of reputational capital and litigation costs, are likely to mitigate the adverse effects of NAS. Results using 840 firm‐year observations of Australian companies document a statistically significant inverse relationship between NAS and the value relevance of earnings, and this inverse relationship is weaker for Big 6 auditors, therefore supporting the hypothesis.     

Takeover premiums and the perception of auditor independence and reputation

This study investigates if there is a positive association between takeover premiums and the bidder’s perception of target firm auditor reputation and independence. Using auditor size as a proxy for auditor reputation, the results indicate that in hostile takeovers target shareholders receive a higher takeover premium when a Big 4 auditor audits the target firm prior to the takeover. This result is only significant, however, in the period prior to the highly publicised audit failures. The impact of perceived auditor independence on takeover premiums is studied using the levels and size of non-audit service (NAS) fees provided by the target firm auditor. Using three proxies for auditor independence, the results show no association between perceived auditor independence and takeover premiums. This finding is robust to partitioning the sample by auditor size, takeover hostility and splitting the sample into takeovers pre- and post- the corporate scandals that occurred in 2002.     

Costs Associated With Going-Concern-Modified Audit Opinions: An Analysis of the Australian Audit Market

This article examines the potential costs to Australian auditors and their clients from the issuance of first-time going-concern-modified audit opinions. We examine the population of Australian companies receiving a first-time going-concern-modified audit opinion during the period 1994–97 and a matched sample of financially distressed firms receiving a clean audit opinion. Results indicate that auditor switching is positively associated with receipt of a going-concern-modified opinion. However, we find no empirical evidence that there is a self-fulfilling prophecy of increased probability of company failure following the issuance of a going-concern-modified opinion for the Australian companies in our study. Our analyses of lost audit fees indicate that auditors issuing first-time going-concern-modified audit opinions lost proportionately more fees by losing clients (through switching or company failure) than firms not issuing a going-concern-modified opinion to financially stressed clients.     

Audit committee diligence around initial audit engagement

Studies focusing on governance mechanisms argue that auditor monitoring is one of several governance mechanisms that exist in the firm, and these mechanisms supplement each other. Extending this argument, I examine whether firms support auditor monitoring with audit committee monitoring when auditor oversight is deemed to be weak. Prior auditing literature argues that audit quality is affected by auditors' lack of familiarity with their clients' activities. Since lack of auditor–client familiarity exists in the first year of auditor–client tenure, I examine whether firms increase their audit committee monitoring during the year of auditor change. For a sample of firms that changed auditors between 2006 and 2012, the findings show that audit committees meet more frequently in the first year of audit engagement. Further tests show that firms' past reporting behavior play a significant role in the demand for more audit committee meetings and the increase in the audit committee meetings in the initial year of auditor engagement positively affects reporting quality.     

企业集团统一审计与审计质量

The influence of judges' attitudes on liability assessments related to failed audits exhibiting significant audit team over-time or significant use of off-shore auditors

This study provides evidence on how audit firms' decisions to use offshore (outsourced) auditors or to assign on-site (local) auditors extensive overtime affect judges' evaluation of auditor legal liability I conduct a behavioral experiment in which actual judges responded to a hypothetical audit lawsuit. The results suggest auditors may be penalized during the litigation process depending on the extent of overtime or off-shoring and judges' attitude toward the public accounting profession. Judges with a positive attitude toward public accounting assessed more liability for an audit firm that used offshore (outsourced) auditors than for the use of extensive overtime for on-site auditors or a control condition. However, judges with a negative attitude toward the auditing profession assessed higher liability for auditors except when on-site auditors bore significant overtime in the final weeks of the audit.     

Conservative Reporting and the Incremental Effect of Mandatory Audit Firm Rotation Policy: A Comparative Analysis of Audit Partner Rotation vs Audit Firm Rotation in South Korea

In this paper, we take advantage of Korea's unique experiment with mandatory audit firm rotation (MAFR) and mandatory audit partner rotation (MAPR) to ascertain their influence on audit quality, proxied by conditional conservatism. Overall, we find that the implementation of MAFR did not have the desired effect. Firms that adopted MAFR demonstrate higher levels of conservatism in previous periods under MAPR (or compared to voluntary adopters). Furthermore, we find that audit tenure increases conservatism levels consistent with the auditor expertise hypothesis. However, whilst evidence suggests MAFR decreases audit quality on the whole, we find that firms that switch from non‐Big 4 to Big 4 auditors demonstrate higher conservatism because Big 4 auditors are more likely to demand conservative accounting practices, consistent with Big 4 audit firm knowledge superiority. Overall, the results suggest that MAFR's negative effect on audit quality can be mitigated by Big 4 auditor supervision.
