Audit Labor Usage and Fees under Business Risk Auditing

The adoption of business risk audit (BRA) approaches during the 1990s by several leading audit firms has been the subject of considerable scrutiny and commentary. Under BRA, the auditor responds to the increasing complexity of auditee financial reports by acquiring a deep and comprehensive understanding of the auditee's industry, strategy, business models, and processes—tasks best accomplished by higher-ranked labor—and by employing this understanding to make audit labor allocations. Using proprietary data for 165 audits conducted in 2002, we investigate three propositions about audit labor use under BRA. First, relative to pre-BRA benchmarks for the same auditor, we expect BRA audits to use a greater proportion of higher-ranked labor. Second, we expect engagements with high assessed auditor business risk (ABR), a summary risk assessment that reflects the BRA auditor's rich understanding of the auditee, to be allocated more labor and more higher-ranked labor than pre-BRA benchmarks. Third, at all ranks of labor, we expect a positive association between assessed ABR and levels of labor use. We find empirical evidence consistent with these propositions. We also find that total labor use in our sample is only modestly lower than pre-BRA norms. Analysis of fee data from these engagements suggests that audit fees in 2002 are substantially less than would be expected under pre-BRA benchmarks. After controlling for audit labor use, both total fees and fees per hour increase with assessed ABR for first-year auditees but not for continuing auditees. Overall, our results provide evidence on the impact of the BRA audit regime and speak to the likely impact of BRA on audit effectiveness and efficiency.     

The effect of external audits of internal control over financial reporting on financial reporting for clients of Big 4, Second-tier,and small audit firms

The external audit of internal control over financial reporting (ICFR) is a very expensive and contentious aspect of the Sarbanes–Oxley Act (SOX). Larger public firms were first required to file a management report on and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the audit requirement. Whereas most related prior research investigates the combined effect of management and auditor reports on financial reporting, this study examines the distinct effect of auditor reports on reporting quality. For companies audited by small auditors, we find evidence that financial reporting quality improves with an auditor report on ICFR. We find no evidence that auditor ICFR reports improve reporting quality for clients of Big 4 or Second-tier audit firms. Our study adds to the debate on the applicability of SOX Section 404 to smaller firms.     

A survey of models for determining optimal audit strategies

The problem studied in this survey is how to optimize the allocation of audit resources over an auditee population with respect to available population statistics. The auditees are assumed to optimize their expected utility based on information about the audit strategy. This survey is limited to models where the auditee can vary the fraud amount along a continuous scale.If the auditor is not able or willing to announce the audit strategy, a Nash equilibrium can be derived in which the auditor and auditee correctly anticipate each other's strategies. If the auditor announces the audit strategy in advance, the problem is formulated as a sequential game with perfect information which is solved as an optimization problem.Early models in the literature resulted in unrealistically high degrees of fraud. Later models have incorporated a split into one group of inherently honest auditees and another group of potentially dishonest auditees. The fraction of inherently honest auditees is exogenous.In this paper, the four combinations of non-announcing/pre-announcing the strategy and all potentially dishonest/some inherently honest auditees are studied. For the case of pre-announcing the strategy with some inherently honest auditees, two new solution methods are presented.Two main conclusions are as follows. First, models with some inherently honest auditees have greater external validity. Second, when a pre-announced strategy is feasible, as it often is with tax and benefit audits, the pre-announced strategy is preferred by the auditor over the non-announced strategy.     

Late for a very important date: financial reporting and audit implications of late 10-K filings

Delays in financial reports often reflect issues related to period-end accounting and audit processes. We investigate the impact of filing delays in connection with auditor characteristics on the quality of financial statements in a sample of firms that filed Form 10-K after the statutory due date. We find that late filing firms are associated with lower financial reporting quality compared to timely filing firms matched by propensity scores, where financial reporting quality is measured by the absolute value of performance-matched discretionary accruals and the probability of a late filing being restated in subsequent periods. Furthermore, we demonstrate that the adverse consequences of late filings can be largely mitigated by having a Big 4 auditor. The differential audit quality stems primarily from Big 4 auditors in large offices and is more pronounced when an auditor may need to draw on additional resources in a limited period.     

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。     

Internal control reporting differences among public and governmental auditors: The case of city and county Circular A-133 audits

We investigate potential differences in audit reporting outcomes between Circular A-133 audits performed by governmental auditors vs. those performed by certified public accounting (CPA) firms. Specifically, we investigate the association between auditor type and the likelihood of auditor-disclosed internal control concerns. We employ a cross-sectional sample of 13,386 single audit reports of US cities and counties during 2004–2006. In contrast to prior literature, the results indicate that in the post-Sarbanes–Oxley environment, CPA firms appear more likely to issue audit reports that identify internal control concerns than are governmental auditors in the context of Circular A-133 audits. The differences are more pronounced for larger CPA firms.     

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.     

Audit Firm Tenure and Audit Quality in a Constrained Market

We examine the relation between audit quality and audit firm tenure in the Iranian audit market, which is constrained by government policies that create intense competition for clients among many small audit firms. We develop arguments that these circumstances create cost pressures that entrench low audit quality and render auditors' plans more predictable to managers wishing to misstate their accounts. Using publicly available data for the audits of listed companies in Iran prior to mandatory audit firm rotation and the incidence of misstated financial reports identified by the Iranian Association of Certified Public Accountants Inspection Office, we find that the likelihood of a misstatement is lowest in the first two years of audit firm tenure. We also find that the likelihood of misstatement is not associated with the year preceding a mandatory audit firm rotation, suggesting outgoing auditor effort is not sensitive to the prospect of subsequent revelations of deficiencies. Although our results from a pre-mandatory rotation period show that frequent rotations appear to improve the financial reporting quality in our sample, we are wary of interpreting these results as support for the mandatory audit firm rotation policy in Iran. Rather, we suggest this is a peculiar consequence of deficiencies in audit quality inherent in the Iranian market.     

New Auditors’ Decisions for Released Firms from the Mandatory Auditor Designation Rule: Evidence From South Korea

This study examines the effect of the mandatory designation rule on audit fees charged and audit hours rendered by auditors for firms released from the mandatory auditor designation rule in the Korean audit market. Under the mandatory auditor designation rule, which took effect in 1991, problematic firms are assigned new auditors by the Financial Supervisory Service. Previous studies suggest that this regulation positively affects the quality of audits by promoting auditor independence. Thus, this study hypothesises that firms that have been subjected to mandatory auditor designation improve the quality of their financial reporting, and that auditors hired after the mandatory designation period account for reduced audit risks when determining audit fees and audit hours. This study shows that audit fees and audit hours of firms released from the mandatory auditor designation rule are lower than those of other initial audit engagements. Taken together, this study's findings reinforce the notion that auditors’ perceptions of changes in audit risk yield corresponding changes in the audit fees they charge and audit hours they render.     

Financial reporting quality and outsourcing of accounting tasks: Evidence from small private firms

This study explores whether the financial reporting quality of small firms differs between firms that outsource accounting tasks and firms that perform these tasks internally. Using accruals quality as a measure for the financial reporting quality and a sample of small Finnish limited liability firms, we find that the quality among the firms is positively related to the decision of purchasing accounting services from an external service provider. This result is also economically significant. The evidence shows that outsourcing of accounting tasks such as the preparation of the statutory financial statements and longer outsourcing relationships increases reporting quality. However, outsourcing of additional tasks, such as payroll processing, does not result in higher quality. These findings are consistent with previous studies showing that small firms in general lack the resources and expertise to prepare high quality financial reports. We provide evidence of an important yet under-researched area of financial reporting quality among small firms.     

Audit quality,accruals quality and the cost of equity in an emerging market: Evidence from Vietnam

This study explores the relationship between audit quality, accruals quality, and the cost of equity in the context of Vietnam. Particularly, we examine the impact of auditor size and accruals quality on the industry-adjusted earnings – price ratio. Using a sample of Vietnamese listed companies, the study shows that firms audited by a Big Four auditor are associated with a lower cost of equity than firms with a non-Big Four auditor. The results indicate that the auditors' information role is more relevant than the insurance role in a civil law context with a relatively low auditor litigation risk. In addition, the findings show that companies with better accruals quality are associated with a lower cost of equity. The study has implications for managers and regulators. The findings highlight the importance of ensuring sound auditing practices and maintaining high-quality financial reporting for corporations.

Switching due diligence auditor in Chinese mergers and acquisitions

The routine financial reporting auditor (FR auditor) of an acquiring firm has the advantage of knowing the acquirer very well, however, a large portion of acquirers in China do not use their FR auditor to continue serve as their due diligence auditor (DD auditor) in the takeover process. Using a sample of 818 takeover transactions from 2004 to 2014, we find that the acquiring firms are more likely to appoint a new DD auditor for M&A, instead of using the incumbent one, when the FR auditor is not an industry specialist and the acquiring firms’ financial reporting quality is low. For low financial reporting quality acquiring firms, changing to a new DD auditor can prevent negative market reactions when firms make the M&A announcement, but firms have to pay a higher premium. Our results remain robust when using alternative definitions of industry specialisation and measures of financial reporting quality.     

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.     

FRC intervention,financial reporting quality and due diligence

This study provides evidence of the relationship between government intervention, financial reporting quality and due diligence. Specifically, the authors examine the consequences of the disclosure of inspection reports by the Financial Reporting Council (FRC) for individual audit firms inspected in the UK. Using a difference-in-differences design, it is found that clients are more likely to receive qualified audit opinions during the post-disclosure period. This significant impact on reporting decisions is more concentrated among clients of small audit firms. Moreover, despite general efficiency during the sample period, clients affected by an FRC intervention experience longer delays in receiving their audit reports. Overall, this study contributes to literature on corporate governance and audit regulation, and has implications for policy making. FRC inspections are of greater concern to small audit firms than large firms, as the latter have already built a strong reputation. In general, the transparent inspection process may be beneficial in enhancing auditor oversight.     

Audit Firm Tenure,Non‐Audit Services,and Internal Assessments of Audit Quality

We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor‐provided non‐audit services (NAS) on audit quality. We find that first‐year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first‐year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor‐provided NAS.     

Institutional Ownership and the Selection of Industry Specialist Auditors

This study provides evidence linking corporate governance mechanisms to the choice of auditor, namely industry specialists. Given that institutional investors are likely to prefer higher quality financial reports to lower quality reports, we theorize that institutional investors will influence managers of companies in which they invest to improve reporting quality by using higher quality, industry specialist auditors. Our findings indicate that firms having relatively greater levels of institutional ownership tend to employ industry specialist audit firms. The results of this study contribute to an understanding of an important facet of corporate governance, the selection of a high quality audit firm.     

Costs and benefits of auditors' disclosure of critical audit matters: Initial evidence from the United States

In an effort to make audit reports more informative to financial statement users, the Public Company Accounting Oversight Board (PCAOB) requires an expanded audit report in which auditors are required to disclose critical audit matters (CAMs). The new standard (AS 3101) became effective for audits of financial statements of large accelerated filers for fiscal years ending on or after June 30, 2019. Using a sample of annual reports of large accelerated filers with and without CAM disclosures, we examine the costs and benefits of the mandatory disclosure of CAMs in auditors' reports. Our evidence suggests that compared to auditor reports reporting no CAMs, the presence of a single CAM disclosure in the auditor's report provides incremental information to equity investors without a significant increase in audit costs. However, using the benchmark of a single CAM disclosure, multiple CAMs in an auditor's report results in higher audit fees and longer audit delays.     

事务所审计任期会影响审计质量吗?——来自发布补充更正公告的上市公司的经验证据

本文以中国A股市场上针对2003年至2009年年报发布过补充更正公告的上市公司为研究样本,对事务所任期与审计质量之间的关系进行了重新讨论。与现有文献不同,我们在讨论中引入了审计风险的概念。我们发现,虽然从整体上看,事务所任期越长,审计质量越差。但是,进一步的分析发现,这一现象仅仅存在于涉及到的审计风险相对较低的上市公司中,而对于补充更正内容涉及到的审计风险相对较高的上市公司来说,事务所审计任期对审计质量并没有产生显著影响。我们的分析结果表明,事务所任期对审计质量的影响是有限的。在较高的审计风险水平下,事务所不会因为任期较长而丧失审计独立性。
