Do PCAOB Inspections Improve the Quality of Internal Control Audits?

We investigate whether Public Company Accounting Oversight Board (PCAOB) inspections affect the quality of internal control audits. Our research design improves on prior studies by exploiting both cross‐sectional and time‐series variation in the content of PCAOB inspection reports, while also controlling for audit firm and year fixed effects, effectively achieving a difference‐in‐differences research design. We find that when PCAOB inspectors report higher rates of deficiencies in internal control audits, auditors respond by increasing the issuance of adverse internal control opinions. We also find that auditors issue more adverse internal control opinions to clients with concurrent misstatements, who thus genuinely warrant adverse opinions. We further find that higher inspection deficiency rates lead to higher audit fees, consistent with PCAOB inspections prompting auditors to undertake costly remediation efforts. Taken together, our results are consistent with the PCAOB inspections improving the quality of internal control audits by prompting auditors to remediate deficiencies in their audits of internal controls.     

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.     

Management letter comments: Their determinants and their association with financial reporting quality in local government

The issuance of management letters (MLs) as part of financial statement audits is a long-standing practice; however, previous studies of MLs are few and no previous research has tested the utility of MLs empirically. This paper reports a study of MLs issued by independent CPA firms pursuant to audits of Florida general purpose local governments. We investigate the determinants of ML comments, finding that such comments are influenced by auditee characteristics and auditor tenure but not by auditor specialization, a proxy for audit quality. Further, we explore the relationship between MLs and financial reporting quality. We observe a negative relationship between first-year ML comments and assessed financial reporting quality. When lagged one year, first-year ML comments bear a positive relationship with financial reporting quality. The absence of ML comments is positively associated with financial reporting quality. Our results suggest that MLs are beneficial to auditees. As such, our study should be interesting to policymakers, users of financial reports, auditees, and auditors.     

Audit Quality in New Zealand – Early Evidence from the Regulator

This study examines the impact of audit regulation in New Zealand, using audit quality reviews undertaken by the Financial Markets Authority (FMA) between 2013 and 2017. Regulation has more than halved the number of registered audit firms indicating that it imposes costs on audit firms. The results show that audit quality is improving, but a high proportion of audits do not meet the FMA's requirements. A key area for improvement is the consistency of quality across audits performed by the same audit firm. The FMA advises audit firms to investigate the underlying cause of audit deficiencies to ensure that internal quality control systems are effective in producing high‐quality audits on a regular basis. A comparison of audit file ratings with the United Kingdom shows that New Zealand's audit quality is much lower. The variation in audit quality across countries concerns the International Forum of Independent Audit Regulators (IFIAR) as it has the potential to undermine stakeholder confidence in the audit industry. Thus monitoring progress in improving audit quality in New Zealand is important. This paper provides insights into audit quality at a country level, whereas most research focuses on the firm level.     

国家审计、内部审计与注册会计师审计的协调与贯通

我国审计体系依据审计主体的不同,划分包括国家审计、内部审计和注册会计师审计三种审计力量。三大审计主体之间既有区别也有联系。三者之间的区别即工作目标、工作依据不同。三者之间的联系主要体现在国家审计对内部审计、注册会计师审计具有领导作用;内部审计以及注册会计师审计应接受国家审计机关的监督和指导,以便促进三种审计力量的有效相互配合,更好的服务于国家治理。为推动我国国家治理现代化的实现,进一步加强三大审计主体之间的协调与贯通是很有必要的。     

The comparative effect of process and outcome accountability in enhancing professional scepticism

Responding to concerns about insufficient professional scepticism in audits (e.g. PCAOB, 2011 , 2012 ; ASIC, 2012 ), we investigate the effect of process and outcome accountability in enhancing the level of professional scepticism and the differences in effects across audit experience levels. In our experiment, we manipulate the type of accountability (outcome versus process) for both novice auditors and audit seniors. We examine the effect on four measures of professional scepticism and find that auditors show greater levels of professional scepticism when they are expected to justify their judgment process, rather than their final judgments. Our results also show that the professional scepticism of novice auditors improves to a greater extent than that of more experienced auditors (audit seniors) under process accountability.     

Audit committee quality indices,reporting quality and firm value

We investigate the relation between audit committee (AC) quality indices, financial reporting, internal control quality and firm value using a US dataset for the period 2002–12. The indices are developed by linking firm value with principal component analysis (PCA) factors based on a broad set of 82 AC variables, some of which influence the quality of the AC, but are not addressed in prior literature. Significant AC factors include ‘overlapping directors’, ‘busyness’ and ‘foreign director’, and we use these factors to develop ‘high’ and ‘low’ AC quality indices. We show that low AC quality firms are more likely to manage earnings, be external auditor dependent with respect to non‐audit tax services, and switch to a lower quality auditor. Low AC quality firms are also more likely to have internal control concerns disclosed by predecessor auditors, including accounting issues, financial restatements, audit opinion concerns and deficiencies that undermine internal control effectiveness. Further, they are more likely to receive an audit report containing additional explanatory notes. Conversely, high AC quality firms are significantly less likely to have these concerns. Our findings highlight the value of using AC quality indices in delivering greater oversight of the financial reporting process.     

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.     

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.     

Do Control Effectiveness Disclosures Require SOX 404(b) Internal Control Audits? A Natural Experiment with Small U.S. Public Companies

We use incremental and joint implementation of multiple SOX‐based control effectiveness disclosure and audit mandates to assess relative performance of alternatives for small U.S. public companies. Using data from several low‐ and high‐effort management disclosure and audit regimes implemented from 2003 to 2008, we find substantial and statistically significant increases in material weakness disclosure rates for small firms undergoing initial SOX 404(b) internal control audits, but find quantitatively and statistically similar increases for initial management reports of small firms exempt from such audits. As to audit cost, fees more than double for initial 404(b) audits in 2004 and remain high, while 404(b)‐exempt firms’ fees grow about 10% annually. Our results support the view that, for small firms, management internal control reports and traditional financial audits may be a cost effective disclosure alternative to full application of SOX 404(b). Also, our results suggest that, even without management reports on internal control, analysis of the cause of known accounting mistakes may yield substantial material weakness disclosures.     

State audit budgets and market assessments of credit risk

While financial statement auditing dominates the market for corporate auditing, internal controls and operational auditing appear to be emphasized in governmental markets. The size of the governmental audit budget (beyond the minimum level prescribed by generally accepted auditing standards) is ultimately a cost/benefit decision, with lower borrowing costs being one of several potential benefits. In testing for empirical regularities between auditing quantity and investor decisions, we found the size of the audit budget to be indeed associated with borrowing costs, but the direction of the relationship was anomalous. The anomalous positive sign for the audit budget variable could be due to self-selection bias. Self-selection bias is a confounding effect that has come up repeatedly to muddy the interpretation of empirical findings in prior (corporate) market based research on discretionary accounting variables. The supply of (discretionary) internal and operational audits may be driven by operational considerations (e.g., internal control weaknesses), which cannot be directly observed by outsiders. The bond markets may be interpreting the size of the audit budget as a signal about underlying economic characteristics that make the state a more risky investment. Alternatively, larger state audit budgets may signal less use of private sector auditors and be interpreted as less useful to investors (though, possibly more useful to governmental concerns focusing on compliance issues). Despite the inclusion of CPAs' audit fees in state budgets, the signal “inferred” for the state's municipalities may have a carryover effect onto state issues.     

CPAs and Big 4 office audit quality

Both accounting firms and regulators recognize the importance of human capital in the audit function, yet we know little about whether and how the level of professionally qualified human capital varies across offices of an audit firm and whether it is associated with audit quality. In this paper, we examine the association between office professionally qualified human capital and audit quality. Using hand-collected data on Big 4 audit firm office CPA levels from 30 U.S. cities, we find that offices with relatively more professionally qualified human capital deliver higher quality audits, with this benefit being more pronounced for audits performed during busy season than for non-busy season audits. The results underscore the importance of the availability of professionally qualified human capital in an audit office to the office’s audit quality. Our finding of CPA levels being an office-level audit quality indicator will potentially help the PCAOB in their ongoing Audit Quality Indicator (AQI) project, whose goal is to assist audit firms, clients, and investors in measuring audit quality. Furthermore, the results lend credibility toward the CPA designation, which helps justify the AICPA’s, NASBA’s, and state Accountancy Boards’ regulatory roles of admitting and licensing qualified candidates.     

A study of whistleblowing among trainee auditors

Over the last number of years whistleblowers have been gaining prominence. This paper investigates some of the factors that influence the propensity or willingness to blow the whistle among trainee auditors. Three categories of factors are examined: audit firm organisational structures, personal characteristics of whistleblowers and situational variables.A survey of 240 final year students of the Institute of Chartered Accountants in Ireland was undertaken. Trainee auditors (just about to sit their finals) were asked about their confidence in internal and external reporting structures in their firms. Using four scenarios, audit trainees were questioned on their willingness to challenge an audit partner's inappropriate response to concerns raised during the audit. Finally, audit trainees were asked about the influence of legal protection on their likelihood of whistleblowing.Results indicate that where firms have adequate formal structures for reporting wrongdoing, trainee auditors are more likely to report wrongdoing and have greater confidence that this will not adversely affect their careers. Training increases this confidence. Trainee auditors also express a willingness to challenge an audit partner's unsatisfactory response to wrongdoing. Significant differences were found in attitudes depending on whether the reports of wrongdoing were internal or external. The willingness to report wrongdoing externally reduces for older (aged over 25) trainees.     

Internal control audits: Judges' perceptions of the credibility of the financial reporting process and likely auditor liability

This paper reports the results of a study in which fifty-seven sitting United States judges participated in a behavioral experiment to assess the perceived credibility of the financial reporting process and the legal risk auditors bear under conditions where they provide an internal control audit report (vs. no report) under two corporate governance environments. We find that participating judges believe internal control audits provide enhanced assurance that intentional misstatements do not exist and also serve to provide elevated protection to the public, but only under conditions of a strong corporate governance environment beyond current regulatory requirements. We also find that, after being informed of an undetected material fraud, judges who currently have high expectations of the auditing profession find auditors more liable when an internal control audit report has been issued (as compared to when no such report has been issued).     

Measuring audit quality of local governments in England and Wales

The purpose of this paper is to model and test the audit quality provided to local governments in England and Wales. A key question is: are there major differences in audit quality provided? The Audit Commission, a national public body under Parliament, regulates the audits. It sets audit standards, appoints the auditors, and (although each auditor and client local government set the specific audit fee for that client) it establishes a formula to determine standard audit fees. The Audit Commission also conducts an annual review of the audit quality provided by the selected auditors, as well as a survey of client satisfaction. The majority of audits are conducted by District Auditors (public sector employees of the Audit Commission). About a quarter of local governments are audited by one of six private sector auditors (including three of the Big 4). Actual results indicate that audit quality differences are associated with the number of governmental audit clients and local government type. Generally, there were modest quality differences by auditor category.     

Group audits: Are audit quality and price associated with the Lead auditor’s decision to accept responsibility?

Lead auditors frequently rely on work performed by Other auditors, especially when auditing clients with operations in multiple countries. The PCAOB has expressed concern that the quality of such group audits may differ depending on whether the Lead auditor accepts or declines responsibility for work done by Other auditors. The PCAOB also has been concerned with the venue through which Lead auditors and Other auditors disclose their participation in group audits, including disclosure of whether Lead auditors accept or decline responsibility. To investigate these issues, we employ a sample consisting entirely of group audit engagements. We identify Lead auditors taking responsibility from PCAOB Form 2, filed by Other auditors of U.S. registrants for fiscal years 2009 to 2017. We identify Lead auditors not accepting responsibility from audit report disclosures during the same period. The results suggest that Lead auditors accepting responsibility charge higher audit fees but provide audits of no higher quality, and possibly of even lower quality. These results are robust to various additional analyses. Our research contributes to the ongoing debate over how the participation of Other auditors affects audit quality.     

监管风险、事务所规模与审计质量

我国会计师事务所规模与审计质量之间是否存在正相关关系,现有研究一直存在争议。本文从注册会计师的执业环境出发,对此进行了重新审视。用上市公司实际控制人的控制权与现金流权之差衡量事务所面临的监管风险,研究发现,大事务所只对监管风险较高的客户提供高质量的审计服务。进一步的研究表明,事务所面临的监管环境改善后,大事务所才对所有客户提供高质量的审计服务,审计质量与事务所规模之间的正相关关系不再依赖监管风险而存在。因此,在法律环境相对薄弱的情况下,加强监管是促使会计师事务所提供高质量审计服务的有效机制。     

An Empirical Investigation of the Interface Between Internal and External Auditors

Professional standards place specific responsibilities on auditors for the discovery of material mis-statements in reports of corporate financial performance. Certain factors have been shown to increase the likelihood of fraudulent financial reporting. One warning sign is the potentially pervasive effect of a weak internal control environment consistent with a weak internal audit group. This study investigates the impact of internal audit department quality differences on auditors ‘willingness to place reliance on the work performed by internal auditors. The study also gives consideration to auditors’ recent experiences with material errors and irregularities and examines the influence of two previously untested individual auditor differences on audit judgment decisions: (1) conflict management style and (2) perception of internal/external auditor communication barriers. The results indicate that auditors attend to internal audit department quality differences and that individual auditor differences exhibit significant influence over auditor judgments. Implications for audit practice are considered and directions for future research are suggested.     

Audit office size,audit quality and audit pricing: evidence from small- and medium-sized enterprises

Using Swedish data, we investigate how audit quality and audit pricing vary with audit firm and office size. In contrast to prior studies, we use disciplinary sanctions issued against auditors not meeting the quality requirement as the measure of audit quality. We find no significant differences in the likelihood of sanctions between Big 4 audit firms and the fifth and sixth largest audit firms in Sweden (Grant Thornton and BDO). We refer to these collectively as ‘Top 6’. However, we find that the probabilities of warnings or exclusions from the profession are much higher for non-Top 6 auditors in Sweden than for Top 6 auditors. Furthermore, we find a strong negative association between the likelihood of sanctions and audit office size for non-Top 6 auditors. This association is insignificant for Top 6 audit firms. Audit fees follow a similar pattern and indicate that larger audit firms and offices put in more effort or have greater expertise. These results suggest that audit quality is differentiated in the private segment market. However, contrary to prior studies, our results suggest that the important dimensions are Top 6 versus non-Top 6 and the office size of non-Top 6 audit firms.     

Big Six auditors and audit quality: The Korean evidence

This study investigates the association between discretionary accruals and Big Six and non-Big Six auditors, and the direction of auditor change. We hypothesize that there is no significant difference in discretionary accruals between Big Six and non-Big Six clients when there is low incentive for auditors to provide high-quality audits, as in Korea.Upon examination of the discretionary accruals of firms listed on the Korean Stock Exchange from 1994 to 1998, we find there is no significant difference between the discretionary accruals of firms with Big Six and non-Big Six auditors. This holds true for firms that switch from non-Big Six to Big Six auditors and vice versa. These resources imply that there may be no difference in audit quality between Big Six and non-Big Six auditors in Korea. This is consistent with other studies in Korea, while inconsistent with the findings of previous studies on audit quality in other countries.
