On the effort-saving effect of audit committee–auditor interlocking

Using unique data on audit hours from China, this paper investigates the effort-saving effect of the audit committee–auditor interlocking (AClk). We find that AClk is negatively associated with audit effort without any deterioration in audit quality. The results suggest that AClk has an effort-saving effect through information sharing between interlocked audit committee members and auditors. However, auditors retain the effort-saving benefits of AClk without sharing them with their client firms. Further analysis shows that the effort-saving effect of AClk is more pronounced for client firms whose auditors have industry expertise, for client firms that share the same individual auditor, or for client firms that share audit committee members with financial expertise.     

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.     

Busy auditors,financial reporting timeliness and quality

We investigate whether audit partners with multiple clients are able to complete their audits in a timely fashion, an important but largely unexplored area of academic research. One view is that having multiple clients increases the knowledge and experience of the audit partner resulting in a more efficient and therefore, quicker audit. On the other hand, having multiple clients may over-burden an audit partner resulting in a slower audit process and longer completion times. We find that audit partners with multiple clients take longer to complete their annual audit. More importantly, we also find that companies with busy auditors who take longer to complete their audits also have poorer levels of financial reporting quality. Additionally, in terms of consequences for busy auditors, firms with lengthy audit report lag switched their auditors the next year suggesting that busy audit partners may lose clients if their workload is excessive and they are not able to maintain audit quality. Our results are robust to alternative measures for both audit report lag and audit partner busyness and a range of endogeneity tests. We also undertake simultaneous quantile regression to assess changes in audit report lag depending on the number of audit clients per partner where we find preliminary evidence of a knowledge spill-over effect. Consequently, our results have implications for companies, audit firms, regulators and other key stakeholders.     

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.     

The effect of small audit firms’ failure to remediate the PCAOB’s quality control criticisms on audit market segmentation

This paper examines the role of the Public Company Accounting Oversight Board (PCAOB) quality control inspection program on market segmentation of small firms’ audit services. Specifically, we investigate how non-remediation of quality control criticisms (QCCs) affects the supply and demand of low-quality audits. We find that remediation of QCCs improves audit quality for small accounting firms. However, some small accounting firms do not remediate QCCs (NR firms) and continue to provide low audit quality. We investigate how NR clients react to the disclosure of non-remediation of QCCs. We find that NR clients with low agency costs are more likely to retain NR firms after the disclosure of non-remediation. This finding is consistent with our expectation that voluntary QCC remediation creates a low-quality audit market segment for NR firms. Our findings suggest that the public disclosure of QCCs is not sufficient to remove low-quality auditors. Instead, NR clients use the disclosure of non-remediation of QCCs as a signal to sort themselves into segments based on their demand for audit quality. We are the first to study and find that PCAOB inspections, and specifically the voluntary nature of remediation and public disclosure of lack of remediation, create market segmentation.     

Do supply shocks in the audit partner labor market affect auditor choice? Evidence from a quasi-natural experiment

We examine whether supply shocks in the audit partner labor market induce clients to switch audit partners. We argue that audit partners in their early careers (i.e., junior partners) charge low audit fees to attract clients, which induces client firms to switch from senior partners to junior partners when there are more junior partners available. Utilizing the Big4 localization policy, we find that Big4 clients are more likely to replace senior auditors with junior auditors to cut costs after the policy. Furthermore, the results are mainly driven by clients who are charged high fees. Our empirical evidence enriches the understanding of auditor choice determinants and informs the ongoing debates surrounding new regulations for Big4 firms in China.     

Risk-preparedness mechanism and audit quality: Evidence from mandatory increase of professional indemnity insurance and professional risk fund

We examine the risk-preparing benefits of Chinese audit firms’ professional indemnity insurance (PII) and professional risk fund (PRF) by using the Notice on Adjusting the Application Requirement of Audit Firms for Securities Qualifications as an exogenous shock. This policy requires audit firms to raise the sum of the cumulative compensation limit of their PII and PRF from 6 million to 80 million yuan. It is found, first, that the capital market regards this policy revision as a signal to strengthen investor protection and responds positively; client firms with high audit risks have a stronger response. Second, auditors’ governance of financial information has strengthened, resulting in the significant improvement of their clients’ financial reporting quality, with a stronger effect on firms with higher earnings management risk. There is no evidence that audit firms pass the costs on to their clients. Finally, the mismatch between auditors and new client firms is alleviated. We show that in an emerging market with weak investor protection, establishing a sound risk-preparedness mechanism for audit firms and strengthening the capacity for civil compensation ex post greatly improve the adaptive degree between international auditing standards and the legal environment of China, thereby enhancing the overall service quality of the audit market.     

The impact of customer firm data breaches on the audit fees of their suppliers

This study investigates whether audit risks that accompany data breaches of major customer firms can spillover into the supply chain and affect audit fees of their suppliers. Based on the economic bond that exists between supplier firms and their major customers, we predict that data breach incidents of customer firms will lead to higher audit fees for their respective suppliers. Consistent with customer breaches increasing the audit risk to the supplier, we observe a positive association between breach disclosures made by major customers and audit fees of the supplier firm. This association exists for both internal and external data breaches. We further find that audit fees are increasing with the number of major customers disclosing a breach in a given year. Our results are robust to both a matched sample design and a difference-in-difference approach. Interestingly, we find that while supplier auditors appear to price the risks associated with customer breaches, the breaches do not appear to affect audit quality. The findings of this study are timely and relevant to academics, practitioners, and regulators as supply chains continue to become larger and more complex.     

Code of ethics quality and audit fees

Using a sample of U.S. firms from 2003 to 2018, we examine the effect of an audit client’s code of ethics quality on audit fees. We find that clients with a lower code of ethics quality pay significantly higher audit fees, suggesting that auditors perceive such clients as riskier and charge greater risk premiums. We also find that such clients have higher litigation risk and auditors spend greater effort when auditing such clients. Our study is among the first to demonstrate the role of a client’s code of ethics quality in audit pricing. Overall, our findings are consistent with codes of ethics being useful to auditors in assessing managers’ financial representations and providing value to firms.     

Audit committee quality,auditor independence,and internal control weaknesses

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.     

Audit committee characteristics and financial statement comparability

Financial statement comparability enables weighing the similarities and differences in financial performance between firms. Prior studies mainly focus on the role of accounting standards in the production of comparability, but the role of economic agents has been largely overlooked. We find that a firm's audit committee size and financial expertise affect its financial statement comparability. Financial information tends to be more comparable among industry peers when audit committees are larger and more members have financial and accounting expertise. The effect of audit committee expertise on comparability is stronger for firms with less independent and smaller boards, for firms with non-Big 4 auditors and for firms with CEOs serving as the chairperson of the boards.     

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.     

Social trust and the demand for audit quality

Our study explores the association between social trust and the demand for audit quality. We argue that social trust reduces the demand for audit quality because it mitigates agency problems. By exploring Chinese listed firms, we find that firms in regions with higher social trust are less likely to choose big auditors, suggesting that higher social trust is associated with lower demand for audit quality. This finding arises because social trust disciplines managers by creating norms and relational networks to constrain opportunistic behaviors. Moreover, firms in high-trust regions have higher financial reporting quality, and the influence of social trust is more pronounced for firms with severer agency problems. Our results suggest that social trust allows firms to rely less on quality audits.     

Corporate employment,red flags,and audit effort

U.S. regulatory agencies and congressional oversight committees have expressed concerns that auditors often neglect red flags embedded in the operating characteristics of firms that misstate their financial reports. This study examines whether labor employment decisions, a major part of a firm’s operations, help predict accounting improprieties and consequently play a role in audit planning and pricing. We find that negative abnormal employment changes are associated with a higher likelihood of subsequent financial restatements, accounting irregularities, and lawsuits related to accounting fraud, and generally require greater effort from auditors as manifested by higher audit fees and longer audit report lags. Positive abnormal employment changes are associated with subsequent restatements and longer audit report lags, but not associated with fraud or audit fees. Taken together, the results are consistent with auditors recognizing the individual misstatement risks pertaining to companies’ employment decisions. These results suggest that standard setters, regulators, and practitioners should devote more attention to operational statistics to identify potential red flags.     

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.     

The effect of inspections,rotations and client preferences on staffing decisions

With increased regulatory focus on audits and concerns about whether audit regulation is achieving its stated aims, it is timely to investigate how regulator inspection of audit files and partner rotations may be affecting staffing decisions. This is an important issue, which affects all audits, as the calibre of staff allocated across engagements impacts the quality of audit work delivered. This study reports the results of an experiment where auditor participants allocate staff across two audits, where regulation anticipated (none, inspection, rotation) and a client request for the best staff (absent, present) are manipulated between‐subjects. We find that auditors allocate lower calibre staff when neither an inspection nor rotation is anticipated than when either is anticipated. When an inspection is anticipated, auditors allocate staff with more knowledge and compliance skills. When a rotation is anticipated, auditors allocate staff with more people skills. A client request for the best staff only has an effect when a partner is due to be rotated, where auditors allocate staff with more people skills in response to the client request. Our findings provide greater understanding of staffing decisions, which may affect audit quality if concerns around audit inspections and partner rotations are perceived by auditors as more important than the underlying risk or complexity of an engagement when allocating staff.     

Audit fee lowballing: Determinants,recovery, and future audit quality

Prior research on the link between lowballing (LB) of audit fees and audit quality is inconclusive. Using more recent data and an innovative design, we define LB engagements as those where the audit fee discount is at least 30 percent. We consider three research questions to understand the possible link between LB and audit quality. First, we investigate whether the two variables that are often associated with auditor independence in the literature—non-audit fees and client importance—are related to LB. Second, we test whether lowballing auditors recoup initial audit fee discounts in the future period. Lastly, we investigate the relation between recovery of audit fees and future audit quality. We find that non-audit fees in the first year of engagement are negatively related to the propensity to LB. LB is significantly positively related to client importance for client firms switching from a non-Big N to another non-Big N auditor while the relation is insignificant for client firms switching from a Big N to another Big N auditor. The results of non-audit fees and client importance indicate that economic dependence does not motivate audit firms to lowball. Further, lowballing auditors tend to recoup their initial fee discounts in subsequent periods via increases in audit fees. Using multiple measures of audit quality, we do not find a significant relation between recovery of audit fees and future audit quality. Overall, contrary to regulators’ concerns, our results suggest that LB does not impair audit quality.     

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.     

Audit market concentration,audit fees,and audit quality: A cross-country analysis of complex audit clients

Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market is segmented and that concentration in the Big 4 segment of the market leads to higher audit pricing. Accordingly, our analyses use international data and focus on concentration within the Big 4 group of firms across countries. We find that audit fees are increasing in our concentration measure for clients where the barriers to entry by competing auditors are higher, as proxied by client size, international operations, and IFRS use. Finally, we find evidence that audit quality is decreasing in Big 4 market concentration for these types of engagements. This indicates a wealth transfer from shareholders to audit firms when auditor concentration is high because these complex clients are charged more, but receive audits that are of lower quality.
