Responsiveness of Auditors to the Audit Risk Standards: Unique Evidence from Big 4 Audit Firms

We examine the effect of changes in audit risk standards on the conduct of financial statement audits in a European setting. We investigate this by analysing the audit hours and audit fees for clients of Big 4 audit firms in Finland in 1996 and 2010. Our results show that audit firms became more sensitive to clients’ business risk due to the introduction of the new audit risk standards, with more audit hours allocated to owner-managed companies in 2010 than in 1996, and fewer audit hours allocated to low-risk clients in 2010 than in 1996. Also, the labour mix in the audit team changed for owner-managed companies, with a greater work load carried by junior auditors in 2010 than in 1996. Regarding the price of audit, we find an increase in audit fees for clients with high business risk, while audit fees remained at roughly the same level for low-risk clients. These findings should be of interest to the auditing profession and those involved in the development of auditing regulations.     

审计师收取客户债务风险溢价了吗?

已有研究发现,公司债务风险越高,审计师收取的审计费用越高;然而,审计费用提高的原因可能是审计投入的增加,也可能是审计师收取客户公司的债务风险溢价。由于缺少审计投入的数据,已有研究无法回答审计师是否收取客户公司债务风险溢价的问题。本文以我国A股上市公司为研究样本,运用我国独到的审计工时数据,就此展开相关问题研究。研究发现,在控制了审计投入之后,客户债务风险与审计费用显著正相关,表明审计师收取了客户公司的债务风险溢价。进一步研究表明,审计师对财务状况较差和治理较差的公司以及非国有企业收取更高的债务风险溢价,规模较小的会计师事务所收取的债务风险溢价高于规模较大的会计师事务所。     

Workforce environment and audit fees: International evidence

Using a dataset from 30 countries over the period from 2002 to 2017, we examine the effects of auditing clients’ workforce environment on audit fees as well as the role that national labor market flexibility plays in this relationship. We find evidence that audit fees are significantly lower for firms with a good workforce environment, suggesting that auditors perceive such clients as less risky; as a result, auditors expend less effort and/or charge a lower risk premium. Furthermore, we find this effect to be stronger for firms in countries with a more flexible labor market. Our mediation test results indicate that the relationship between the audit client workforce environment and audit fees is mediated by media coverage of workforce controversies. Our study contributes to the international audit fee literature by identifying employee welfare as a distinct audit pricing factor, above and beyond the effects of overall corporate social responsibility practices.     

Does International Accounting Network Membership Affect Audit Fees and Audit Quality? Evidence From China

Regulators suggest that small audit firms join international accounting networks to reduce their resource constraints in serving large clients and providing high-quality service. Bills, Cunningham, and Myers (2016) investigate the issue in the United States and find that both audit fees and quality are higher for members of international accounting networks (i.e., member audit firms). We investigate the effects of network membership on audit fees and quality in China, a relatively weaker institutional environment than the United States. Using data of Chinese listed companies audited by non-Big N audit firms from 2001 to 2010, we find that member audit firms charge 3.9% higher fees than nonmember audit firms, much lower than the 30% fee premiums charged by U.S. member audit firms. We do not find consistent evidence that audit quality is higher for member audit firms. Overall, our results demonstrate that China's weak institutional environment may overwhelm the quality control brought by international accounting networks and that it may weaken or even offset the benefits of audit firms' participation in these networks, resulting in smaller or even no effects of membership on audit fees and quality.     

The Unintended Consequences of the Frequency of PCAOB Inspection

After more than 50 years of self‐regulation of the US auditing profession, the Sarbanes‐Oxley Act of 2002 (SOX) created the Public Company Accounting Oversight Board (PCAOB) as a quasi‐governmental entity with statutory authority to inspect accounting firms that audit public clients. The frequency of this inspection is annual or triennial, based upon the number of public clients the firm audits. We examine the effects of these two levels of inspection frequency on financial reporting quality and audit fees for clients of small and midsize public accounting firms. Our findings provide evidence of significantly higher audit quality and audit fees for clients of annually inspected firms relative to clients of triennially inspected firms. These findings are robust to auditor‐client alignment analyses, propensity score matching, time‐series analyses, examination of firms that have changed from triennial to annual inspection, and particular examination of firms with inspection deficiencies. Overall, our study suggests that the two‐tier frequency system of PCAOB inspection may have also resulted in two‐tier audit quality and audit fee systems for small and midsize public accounting firms, with more frequent inspection leading to more rigorous and informed auditor decisions. We discuss the implications of our results for the Board and the profession at large.     

Public Attention and Auditor Behavior: The Case of Hurun Rich List in China

Adverse client publicity can entail regulatory scrutiny over audited financial statements and impose political costs on auditors. We use the changes in client publicity caused by their controlling owners’ presence on the Hurun Rich List (the rich listing) in China to test the hypothesis that auditor conservatism increases with client publicity. Our evidence indicates auditors issue more adverse audit opinions to clients and charge higher fees following the rich listing events. Moreover, we observe that auditors strategically respond to clients with different attributes—for clients whose owners accumulated wealth in a more questionable manner, auditors choose more stringent audit reporting to better defend themselves from regulatory scrutiny; for clients without such attributes, auditors primarily rely on increasing audit fees to cope with any post-listing increase in audit risks. Our analyses also suggest the impacts of rich listings tend to be concentrated among large audit firms with stronger reputation concerns or among engagement auditors with more conservative reporting styles. By showing how auditors manage political risks associated with heightened public scrutiny, we contribute to both the auditing and political cost literature.     

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.     

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.     

How do auditors respond to low annual report readability?

We show that increased audit effort is associated with lower annual report readability to compensate for a perceived increase in the risk of financial misstatement for United States (US) firms. In particular, we find that lower annual report readability is associated with longer audit delays and higher audit fees for Form 10-K for US auditors, suggesting that auditors spend more effort auditing clients when annual reports have lower readability. We also find that low readability increases the likelihood of auditors using more explanatory language in unqualified audit reports.     

Effects of audit committee chair characteristics on auditor choice,audit fee and audit quality

We investigate whether the characteristics of audit committee (AC) chairs are associated with decisions about auditor choice, audit fees and audit quality. Using hand-collected Australian data, firms with AC chairs who have longer tenure and multiple AC memberships across several boards are found to be more likely to choose Big 4 and/or industry specialist auditors, pay higher audit fees and have lower discretionary accruals. Those AC chairs with higher business qualifications are more likely to hire a Big 4 auditor, pay higher audit fees and have lower discretionary accruals, while AC chairs with professional qualifications are more likely to hire a Big 4 and/or industry specialist auditor. In contrast, firms with AC chairs who are executive directors are less likely to hire a Big 4 auditor and have higher discretionary accruals. Our findings contribute to the literature by documenting that various characteristics of AC chairs are important for enhancement of auditor selection and 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.     

The vanishing searches and audit fees: Evidence from Google's withdrawal from China

I investigate the impact of the disruption of free information access via search engines on audit fees using a quasi-natural experiment provided by Google's withdrawal from China. Employing a difference-in-differences design, I document an increase in audit fees for firms with overseas business relative to firms without overseas business after Google's withdrawal. The results are robust to matched samples, placebo tests, alternative specifications, excluding alternative explanations and different event windows. This trend in audit fees suggests that Google's withdrawal hampers firms' foreign information streams and increases audit risk and audit effort. Consistent with this argument, after Google's withdrawal, firms with overseas business conduct more earnings management, pay more abnormal audit fees and experience longer audit report lags. Furthermore, the increase in audit fees is greater for firms with poor information environments, more retail investors or non-Big 4 auditors. My findings suggest a potential auditing cost of restricting the free flow of public foreign information about firms.     

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.     

Information sharing between mutual funds and auditors

This paper examines whether there is information sharing between mutual funds and their auditors about the auditors’ other listed firm clients. Using data from the Chinese market, we find that mutual funds earn higher profits from trading in firms that share the same auditors. The effects are more pronounced when firms have a more opaque information environment and when the audit partners for the fund and the partners for the listed firm share school ties. The evidence is consistent with information flowing from auditors to mutual funds, providing mutual funds with an information advantage in firms that share the same auditors. Our findings are robust to the use of audit-firm mergers and acquisitions (M&As) as exogenous shocks and several other robustness checks. We further find that auditors benefit by charging higher audit fees for mutual fund clients and by improving their audit quality for listed firm clients. Our study provides evidence of bi-directional information sharing between two important market intermediaries.     

The determinants of audit fees—evidence from the voluntary sector

Given the growing demand for accountability in the public sector, there is a need to begin to investigate audit pricing issues in this sector. This study makes three contributions. First, it develops and estimates, for the first time, a model of audit fee determinants for the charity sector. As in previous private sector company studies, size, organisational complexity and audit firm location are the major determinants. A positive association between audit fees and fees for non-audit services is also observed. Charity sector factors of empirical significance include the nature of the charity (i.e., grant-making or fund-raising), its area of activity and the importance of trading income. Separate models for grant-making and fund-raising charities reflect the relative complexity of the audit of fund-raising charities. Second, the lower auditor concentration in the charity sector market, compared to the private sector market, permits a more powerful test of whether large firms and/or auditor expertise are rewarded with a fee premium. In the more complex audit environment of fund-raising charities, the results show that Big Six audit firms receive higher audit fees (18.5%, on average) than non-Big Six firms. Also, non-Big Six audit firms with charity expertise are rewarded with a fee premium over other non-Big Six firms. Finally, the study demonstrates that the charity audit fee rate is significantly lower than that of private sector companies; in fact it is approximately half. A change in the reporting of charity audit fees is proposed to reflect any element of ‘charitable giving’ by the audit firm.     

非审计业务对审计市场绩效的影响——基于会计师事务所业务结构的角度

以审计质量和审计收费作为审计市场绩效的衡量指标,从会计师事务所业务结构角度来考察我国注册会计师行业拓展非审计业务对审计市场所带来的影响。实证检验发现,相对于其他事务所而言,非审计业务规模越大和当年非审计业务规模较上年扩大的事务所,其审计质量越好,审计收费也越高。这说明在目前审计服务市场容量有限,竞争过于激烈的环境下,拓展非审计业务有利于增强审计独立性和提高审计收费,是改善行业执业环境的一个重要途径。     

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.     

融资约束、审计费用与现金持有价值

审计费用和现金持有价值是公司财务审计研究领域的两个重要话题。审计费用高低所隐含的公司风险程度影响着投资者对公司增加现金持有量将产生积极还是消极效应的判断,会导致公司股票超额回报率的变化,进而也可能影响其现金持有价值,目前尚无相关的研究。本文以现金持有的边际价值模型为基础,引入审计费用和融资约束变量,对融资约束条件下审计费用与公司现金持有价值的关系进行研究后发现,过高的审计费用会降低公司的现金持有价值,审计费用增加得越多,公司的现金持有价值越低。进一步的分析发现,相对于其面临较高程度的融资约束时,公司面临较低程度的融资约束时审计费用对其现金持有价值的负向影响更为显著。     

Money laundering and audit fees

We investigate the association between state-level money laundering sentences and audit fees in the US. Money laundering measures a broad category of offenses involving financial transactions using funds or monetary instruments gained through criminal activities and tax evasion. We find that firms headquartered in US states with high rates of money laundering sentences pay more audit fees. Our results suggest that auditors incorporate, as a fee premium, the higher risks involved when clients operate in those states. Our result remains robust to alternative specifications of money laundering proxies, and to the inclusion of a number of firm-level and state-level control variables. We also conduct two-stage least squares and propensity score matching analysis to mitigate the endogeneity problem that might arise from omitted variables, reverse causality, or model misspecification problems.     

The impact of financial reporting flexibility on auditor risk judgement: Evidence from the implementation of FIN 46R

This paper investigates how auditors respond, in terms of their pricing and audit work, to a reduction of clients’ financial reporting discretion upon the implementation of FIN 46R, which requires firms to consolidate the variable interest entities (VIE) under their control. Using a difference-in-differences research design, we find that auditors charge relatively fewer audit fees and have shorter audit report lags for firms that are significantly affected by FIN 46R, compared to a group of control firms. This result concurs with the view that auditors react favorably to the reduction of clients’ financial reporting discretion. Our finding is concentrated among clients with higher accrual earnings management constraints, auditors with less client-specific knowledge, and auditors who have no recent experience of audit failures (e.g., severe client restatements). Our results are robust to alternative identifications of treatment and control samples, and our conclusion remains valid after controlling for the contemporaneous adoption of Sarbanes-Oxley (SOX) Act. We also show that the relatively reduced audit fees and audit effort do not lead to the deterioration of audit quality.
