Earnings quality: Some evidence on the role of auditor tenure and auditors’ industry expertise

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.     

Client influence and auditor independence revisited: Evidence from auditor resignations

Financial scandals such as the Enron-Andersen debacle provoke concerns that auditors lack independence when faced with influential clients. Unlike previous studies that examine whether client influence affects audit quality on ongoing engagements (providing mixed results), we investigate whether client influence (which engenders “independence risk”) at the audit-office level affects auditor resignations from high engagement-risk clients. We construct summary measures of engagement risk, using client disclosures on Form 8-K filings, potential risk factors (e.g., litigation risk), and auditor action (e.g., issuance of a going concern opinion) on the previous year’s financial statements. Focusing on risky clients, we find that auditors are more likely on average to resign from influential clients, and this positive association holds for auditors that are less likely to have mechanisms in place to mitigate independence risk. Also, importantly, influential clients are prevalent across the spectrum of client size, and the positive association between client influence and auditor resignations holds for both large and small clients.     

UK investors’ perceptions of auditor independence

The auditor’s role in society is that of validating the truth and fairness of financial statements. If owners of organisations doubt the auditor’s independence, financial statements will lack credibility. This questionnaire-based study investigated how investors perceive three potentially independence-impairing auditor–client relationships: the joint provision of audit and non-audit services, an audit firm’s economic dependence upon a client and long-term relationships between auditor and client. The objective was to determine whether, after a series of high-profile corporate collapses, owners retain faith in the integrity of the auditor. The results suggest that economic dependence and the provision of non-audit services are perceived as greater threats to auditor independence than long-term relationships between the auditor and client.     

The effects on financial statements of the litigation cost rule in a civil action for negligence against the auditor

The litigation cost rule relates to which of the two parties in a civil lawsuit has to pay the legal costs. In those countries where the American system applies, each has to pay their own legal costs. In most other countries, the British system applies and the loser pays all the legal costs. By means of a single person decision-theoretic model, I examine the effects of this on auditing and financial statements under certainty and uncertainty conditions. Generally, the American system has the effect of restraining shareholders from suing unless they are able to cover their legal costs, thereby providing scope for under- or over-statements, depending on management’s wishes. This scope is denied under the British system and, as a result, audited financial statements will not be similarly biased.     

Third-party auditor liability and financial restatements

We examine whether U.S. state-level third-party auditor liability (TPAL) regimes affect firms' financial restatement decisions. Using a sample of 34,409 firm-year observations from 2003 to 2018, we find that state-level TPAL is significantly negatively related to the likelihood of firm-level financial restatements. We also observe that the negative relationship between TPAL and financial restatements persists for a subsample of firms with income-increasing financial restatements and the ‘restatement of torts standard’ (one of the more expansive subgroups of TPAL). Using a difference-in-differences regression design, we find that an increase in state-level TPAL regimes strengthens the negative relationship between TPAL and the incidence of restatements. Our main finding remains robust across several sensitivity tests. Finally, we find that the negative relationship between TPAL and restatements is more pronounced when firms are subject to greater litigation risk and when firms are audited by non-specialist auditors. Overall, we show that TPAL has important implications for client firms' financial restatements.     

Market reactions to auditor switches under regulatory consent and market driven regimes

We examine market reactions to announcements of auditor switches by Australian-listed companies during the ‘regulatory consent’ period (2000–2011) under which auditor resignations require consent by the corporate regulator before taking effect at annual general meetings. Overall, we find no clear evidence of significant market responses to firms announcing auditor switches, consistent with a lack of information content or potential information leakage argument. However, examination of a more recent sample in the ‘partial deregulation’ period (2015–2017), whereby timing and consent provisions have been relaxed under a more market-driven regime, uncovers univariate evidence of market reactions directionally consistent with the audit quality interpretation. Overall, these results provide support for the regulator’s recent initiative to deregulate the auditor resignation process in Australia to become more disclosure driven as in other jurisdictions.     

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.     

Independent and joint effects of audit partner tenure and non-audit fees on audit quality

We examine the individual and joint effects of auditors’ non-audit services (NAS)/abnormal NAS fees and length of audit partner tenure on audit quality. Our results raise questions about the ‘one size fits all’ approach imposed by the current audit partner rotation requirement in Australia as a result of (1) a learning differentiation that we observe between Big 4 and non-Big 4 auditors and (2) higher discretionary accruals associated with non-Big 4 auditors. We find abnormal NAS fees to have a positive association with both absolute and positive (income-increasing) values of discretionary accruals for firms with short audit partner tenure. NAS/abnormal NAS fees are also negatively associated with the issuance of going concern opinions to financially distressed firms when partner tenure is short. In terms of policy implications, regulators are able to gauge the efficacy of the CLERP 9 reforms which currently impose a five year mandatory audit partner rotation requirement.     

The impact of corporate governance on auditor choice: Evidence from China

As the largest and fastest growing emerging market, China is becoming more and more important to investors throughout the world. The purpose of this paper is to investigate the determinants of firms’ auditor choice in China in respect of their corporate governance mechanism. Normally firms have to take a trade-off in their auditor choice decisions, i.e., to hire high-quality auditors to signal effective audit monitoring and good corporate governance to lower their capital raising costs, or to select low-quality auditors with less effective audit monitoring in order to reap private benefits derived from weak corporate governance and less-transparent disclosure (the opaqueness gains). We develop a logit regression model to test the impact of firms’ internal corporate governance mechanism on auditor choice decisions made by IPO firms getting listed during a bear market period of 2001–2004 in China. Three variables are used to proxy for firms’ internal corporate governance mechanism, i.e., the ownership concentration, the size of the supervisory board (SB), and the duality of CEO and chairman of board of directors (BoDs). We classify all auditors in China into large auditors (Top 10) and others (non-Top 10), assuming the large auditors can provide higher quality audit services. The empirical results show that firms with larger controlling shareholders, with smaller size of SB, or in which CEO and BoDs chairman are the same person, are less likely to hire a Top 10 (high-quality) auditor. This suggests that when benefits from lowering capital raising costs are trivial, firms with weaker internal corporate governance mechanism are inclined to choose a low-quality auditor so as to capture and sustain their opaqueness gains. On the other hand, with improvement of corporate governance, firms should be more likely to appoint high-quality auditors.     

The impact of the Social Security Fund on auditor litigation risk

In this study, we examine the effect of the Social Security Fund on auditor litigation risk. Using audit fees as a proxy for auditor perceptions of litigation risk, we find that the Social Security Fund significantly reduces auditor litigation risk. Furthermore, we show that the Social Security Fund influences auditor litigation risk through reducing both the audit risk and the business risk of public companies. In addition, the impact of the Social Security Fund for reducing auditor litigation risk is more obvious in the group of firms with low levels of internal governance, which indicates that the Social Security Fund plays an important governance role as a high-quality institutional investor. In summary, we verify that the Social Security Fund, when acting as an institutional investor, plays an important role in corporate governance, and that it helps to reduce auditor litigation risk. Our results provide empirical support for expanding the governance role of the Social Security Fund as an institutional investor in China’s A-share market.     

The effect of auditor litigation risk on clients' access to bank debt: Evidence from a quasi-experiment

We exploit staggered state-level shocks to third-party auditor legal liability in the U.S. to test whether auditor litigation risk affects client companies' access to private debt markets. We find that an exogenous increase in auditor litigation risk leads to an increase in both clients' likelihood of receiving bank loans and the average amount of the bank loans that clients receive. In support of our proposed mechanism that auditor litigation risk leads to improvements in clients' audit and financial reporting quality, we find that these same shocks lead to a reduction in accruals, an increase in going-concern opinions, a decrease in restatements, and an improvement in accruals' ability to predict future cash flows. We also find that increased auditor litigation risk leads to an increase in the contractibility of clients’ accounting numbers, as proxied by the use of debt covenants, and a decrease in the cost of borrowing.     

Effect of audit report disclosure on auditor litigation risk

Internationally, the escalating number of cases levelled against auditors and the costs of defending such actions has led to the auditing profession calling for measures to reduce their liability burden. Relatively few measures have been taken by the auditing profession by way of adapting the disclosure contained in the audit report to mitigate their litigation risk. This study examines whether the issuance of an audit opinion with a going concern related ‘emphasis of matter’ paragraph or work practices disclosure has any effect on potential litigants' likelihood of pursuing litigation against the auditor. An analysis of 69 responses from advanced law students and 18 practitioners working in corporate liquidation demonstrate that a modified (but not qualified) audit report effectively acts as a ‘red flag’ and reduces potential litigants' propensity to initiate litigation. However, work practices disclosure did not significantly alter potential litigants' inclination to recommend litigation. Despite this finding, respondents (particularly liquidators) indicated that work practices disclosure was an important factor in their litigation decision. These results suggest that further investigation into how to effectively disclose the work done on audit and assurance engagements is needed. This has implications for standard setters and the auditing profession, especially considering recent changes in the disclosure contained in audit and assurance reports.     

Non-audit service and auditor independence: an examination of the Procomp effect

This paper examines whether non-audit service provision impairs auditor independence, and whether the degree of auditor independence in Taiwan changed in the wake of the 2004 Procomp scandal. The auditors involved in the Procomp affair were suspended from practice for 2 years and were sued, and we posit that these unprecedented sanctions and litigation affected subsequent auditor behavior. Considering the measurement errors involved in discretionary accruals, we propose an alternative analytic approach in which the dependent variable in the regression analysis is the difference between audited earnings and forecast earnings, scaled by total assets, and the primary independent variable is the non-audit fees ratio. After controlling for the effects of financial leverage, operating and market performance, industry, company size, audit firm size, management forecast error, and management attempts to manipulate earnings, regression analysis indicates that the coefficient for non-audit fees ratio is negative and significant in 2003 but not in 2004. Using non-audit fees instead of non-audit fees ratio to conduct the regression analysis yields similar results. This finding is consistent with the notion that auditors make a trade-off between gaining service fees and avoiding litigation and reputation loss. Limitations and policy implications are also offered.

The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

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.     

Response to discussants'' comments: The demand for auditor reputation across international markets for audit services

Previous research has documented a positive relation between variation in audit fees across countries and specific macroeconomic factors such as a country's level of litigiousness and the level of required disclosure. Such studies have focused on the supply of auditor services using single-equation models. This study examines not only the supply of but also the demand for large-firm auditors across 20 different countries using the simultaneous-equations approach. This approach is used to account for the endogeneity between choice of auditor and audit fees. The results indicate an association between greater disclosure requirements and the choice of a large-firm auditor. They also indicate that increased litigation and regulation are associated with higher audit fees.     

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.

How individual auditor characteristics impact the likelihood of audit failure: Evidence from China

Audit failure imposes a severe loss on investors and damages market participants' confidence in financial reporting quality. This study investigates the impacts of individual auditor characteristics on the likelihood of audit failure. Chinese regulators mandate listed firms to disclose the engagement auditors' identity. Furthermore, the information regarding individual auditor characteristics in China is also publicly available. Utilizing this unique setting, we examine the relationship between individual auditor characteristics and the likelihood of audit failure in China during the period from 2000 to 2009. We document that individual auditors with more auditing experience are less likely associated with audit failure. We also find a weaker negative relationship between auditor education level and audit failure. Our study has important implications for both auditors and regulators by shedding lights on the determinants of audit failure and by providing guidance to the human resource management in audit firms.     

Government quality,auditor choice and adoption of IFRS: A cross country analysis

We examine the association between country-level government quality and firms' choice of external auditors. Using a cross-sectional sample of 142,193 firm-year observations from 46 countries over 1998–2007, we show that the government quality of a country has a significant positive effect on the likelihood of choosing Big 4 auditors by firms in that country. We also show that firms in countries with strong governments that have adopted IFRS are more likely to choose Big 4 than non-Big 4 auditors. To our knowledge, this is the first study of its kind to provide direct evidence on the role of government quality in firms' choice of external auditors. Choice of a Big 4 auditor may be regarded as a proxy for the demand for high quality financial reporting, and thus the results provide insights for policy makers on the importance of government quality toward improving financial reporting quality in a country.
