The Pricing of Audit Services: Further Evidence from the Canadian Market

Since the seminal work of Simunic (1980), many studies have investigated audit pricing, competition in the audit industry, product differentiation and audit cost functions. This study expands on the work done to date by examining Canadian audit fees across time, audit firm and industry. The observations of audit fee data span the period of time during which the provincial codes of professional ethics with respect to fee tenders and advertising in general were relaxing in Canada. The results reported in this study support the existence of differentiated audit services in the Canadian audit market, and are consistent with DeAngelo's (1981) size interpretation of audit quality. Although no significant differences in the pricing of audit services across time are detected, the data provide evidence of significant pricing differences across (pre-merger) Big Eight audit firms in the small auditee market, suggesting that treating these audit firms as a homogeneous group in future research may not be appropriate. These inter-firm pricing differences do not appear to be due to the potential confounding effects of the auditee's industry. In contrast to previous studies, a significant positive association between internal and external audit costs is observed, suggesting a complementary, rather than a substitute, relationship.     

Competition in the Audit Market: Policy Implications

The audit market's unique combination of features—its role in capital market transparency, mandated demand, and concentrated supply—means it receives considerable attention from policy makers. We explore the effects of two market scenarios that have been the focus of policy discussions: mandatory audit firm rotation and further supply concentration due to the exit of a “Big 4” audit firm. To do so, we first estimate publicly traded firms' demand for auditing services, allowing the services provided by each of the Big 4 to be differentiated products. We then use those estimates to calculate how each scenario would affect client firms' consumer surplus. We estimate that, for U.S. publicly trade firms, mandatory audit firm rotation would induce consumer surplus losses of approximately $2.7 billion if rotation were required after 10 years and $4.7–5.0 billion if after only four years. We find similarly that exit by one of the Big 4 would reduce client firms' surplus by $1.4–1.8 billion. These estimates reflect only the value of firms' lost options to hire the exiting audit firm; they do not include likely fee increases resulting from less competition among audit firms. The latter could result in audit fee increases between $0.75–1.3 billion per year for mandatory rotation and $0.47–0.58 billion per year for the disappearance of a Big 4 audit firm. Such losses are substantial; by comparison, total audit fees for public firms were $11 billion in 2010.     

The Relative Importance of Audit Quality Attributes

Corporate collapses and audit failures have threatened the credibility of the audit function, with audit quality once again being a major issue. Motivated by the significance of auditing and perceptions of audit quality in enhancing the reliability and credibility of financial statements, this article investigates the relative importance of audit team and audit firm attributes in perceptions of audit quality by users of audit services. Data are gathered from 81 users of audit services and analysed using adaptive conjoint analysis in order to measure the relative importance of audit team and audit firm attributes in perceptions of audit quality. The results show that, in general, users of audit services perceive audit team attributes as being relatively more important than audit firm attributes in perceptions of audit quality. The findings of the study have implications for regulators and the accounting profession concerned with improving confidence in corporate governance and the effectiveness and integrity of the audit process, and for audit firms in monitoring and promoting the quality of their audit services.     

会计师事务所的属性重要性与审计收费——基于中国会计师事务所综合评价前百家信息的证据

审计收费是对事务所的审计师团队努力的回报,而审计师团队有多种不同重要程度的属性,因此有必要把会计事务所作为一个拥有多个属性重要性的系统,具体考察其对于审计收费的影响。本文根据中国注册会计师协会年度会计师事务所综合评价前百家信息,具体考察了会计事务所的属性重要性对审计收费的影响。研究表明,事务所中的CPA的教育结构、CPA的经验(年龄)结构和事务所综合规模对审计收费具有显著正向影响。事务所其他属性与审计收费未发现存在显著相关性。     

Fee pressure and the longitudinal dynamics of audit engagement budgeting and reporting

Using longitudinal data from an international accounting firm, this paper investigates how budgeted and reported audit hours change in response to prior budget variances, fee pressure, and budget pressure imposed by audit firm management. This investigation is motivated by concern regarding the association between these factors and quality-reducing audit behaviors. The results for audit firm management budgeting show that budgets increase following unfavorable variances, and that fee pressure does not affect the budgeting process. Regarding engagement team reporting behavior, we find that both prior unfavorable variances and fee pressure are associated with subsequent reduction in reported audit hours. Further, when audit firm management imposes budget pressure on engagement teams, they respond by reducing reported hours. Overall, the results provide evidence on the interplay between audit firm management and engagement teams in responding to prior variances, fee pressure, and budget pressure during the period 2001-2003.     

会计师事务所规模与审计定价——基于中国本土事务所的经验研究

会计师事务所规模与审计收费之间的关系取决于产品差异化、声誉投资、市场势力等三个因素与规模效应之间何者相对占优。对我国A股上市公司2007～2008年数据检验发现,无论是以业务收入、注册会计师人数还是从业人员人数度量事务所规模,事务所规模与审计收费之间都呈显著的正向关系。这表明,大事务所可以收取更高的审计费用。同时,在我国审计市场,规模效应相对于其他三个因素可能不占优势。     

中国本土会计师事务所的市场地位与经济回报

区域规模化和行业专长化是会计师事务所通常采取的两种发展战略。本文分析和比较了具有区域市场领先地位以及具有行业市场领先地位的中国本土会计师事务所伴随的经济回报(以审计定价度量)。基于全样本的证据显示:本土会计师事务所仅仅通过在各省际市场取得领先地位并不足以获取明显的经济回报;具备行业市场领先地位则伴随着显著更高的经济回报;同时具备行业市场领先地位和区域市场领先地位则伴随着更大的经济回报。进一步的分析显示,不同本土会计师事务所可能需要考虑在发展战略及其实现途径上的差异化。本文的发现对本土会计师事务所制定符合自身特征的发展战略具有启示意义。     

The Importance of Audit Firm Characteristics and the Drivers of Auditor Change in UK Listed Companies

This paper explores the importance of audit firm characteristics and the factors motivating auditor change based on questionnaire responses from 210 listed UK companies (a response rate of 70%). Twenty-nine potentially desirable auditor characteristics are identified from the extant literature and their importance elicited. Exploratory factor analysis reduces these variables to eight uncorrelated underlying dimensions: reputation/quality; acceptability to third parties: value for money: ability to provide non-audit services: small audit firm: specialist industry knowledge; non-Big Six large audit firm: and geographical proximity. Insights into the nature of ‘the Big Six factor’ emerge. Two thirds of companies had recently considered changing auditors; the main reasons cited being audit Ice level, dissatisfaction with audit quality and changes in top management. Of those companies that considered change. 73% did not actually do so. the main reasons cited being fee reduction by the incumbent and avoidance of disruption. Thus audit fee levels are both a key precipitator of change and a key factor in retaining the status quo.     

Explaining Variability in External Audit Fees

This study examines the effect of several factors on the level of external audit fees using a multiple regression model. Audit fee data were provided by 95 US publicly held companies for the years 1983 to 1985. Variables measuring client industry membership and auditor involvement in the security registration process were proxies for client regulatory aspects. These variables were significant and provide support for the hypothesis that scale economies and/or specialization effects accrue to audit firms in dealing with the regulatory complexities faced by clients. Variables measuring auditee size and complexity, auditee/auditor loss sharing risk, and audit firm size were also significant in explaining variability in external audit fees.     

Auditor's Engagement Risk and Audit Fees: The Role of Audit Firm Alumni

Abstract:  This study explores the effect of the association of audit firm alumni with their alma mater on audit prices. The tests indicate that there is a moderate reduction of up to 21% in the level of audit fee when alumni (i.e., former employees) of the incumbent audit firm sit on the client board of directors which is consistent with the engagement risk theory. This suggests that there is an 'alumni effect' in the market for audit services. The findings hold only in the large company segment of the market. The results are robust to different model specifications and alternative samples. The sample comprises all executive and non-executive directors who run the UK quoted companies and are simultaneously ICAEW qualified chartered accountants. The study's implications for the accounting profession and the regulators are also discussed.     

The Provision of Non-audit Services and the Pricing of Audit Fees

There have been a number of studies examining audit fees and this research has covered various nations. Recent legislation in Norway requires a company to disclose information on the audit fee and the fees for non-audit services paid to its auditor. Using this data, models of audit fee structure are developed. As with other studies, the size of the company is a major determinant of the audit fee. Payments for non-audit services are positively and significantly associated with audit fees; this relationship is difficult to explain although it parallels some research in the United States. Overall, the models explain about 75 per cent of the variability in audit fees.     

On the Relationship between Audit Tenure and Fees Paid to the Audit Firm and Audit Quality

Abstract

We investigate the impact of audit firm tenure, partner tenure, audit fees, fees for non-audit services and total fees on audit quality, as measured by discretionary accruals. Our sample consists of Spanish non-financial public companies for the years between 2006 and 2013. Results indicate that audit quality increases with audit firm tenure but decreases with partner tenure. Moreover, the level of fees paid to the audit firm seems to have a negative impact on audit quality, which is mainly driven by fees for audit services. In this regard, we do not observe any significant relationship between fees for non-audit services and audit quality. Our results also show that the negative relationship between either long partner tenures or high fees and audit quality does not occur when the tenure with the audit firm is long. Therefore, long audit firm tenures do not only seem to involve higher audit quality ‘per se’, but also moderate the negative effects of partner tenure and audit fees on audit quality. The results of this study, which are robust to several sensitivity checks, may be relevant for the current debate on auditor rotation and the joint provision of audit and non-audit services.     

Audit firm, corporate governance, and audit quality: Evidence from Bahrain

The aim of this research is to document the perceptions of credit and financial analysts with regard to the relationship between the effectiveness of audit committee, size of the auditing firm and audit quality in the context of Bahrain, which is characterized by a developed financial sector, low-liquidity stock market, low turnover in board of directors of listed firms, an inactive merger and acquisitions market and almost non-extent litigation. A survey of 300 credit and financial analysts shows that analysts considered auditors' opinion useful. Both credit and financial analysts see the credibility of financial statements to be a function of the size of the auditing firm. Both groups assume that the characteristics of Big-Four firms allow them to produce better-quality reports than non-Big firms. Non-audit services were found to affect auditor's independence and hence impair audit quality. Both the groups of analysts believe that effective audit committee enhances the quality of audit reports. Financial analysts perceive financial statements to be more credible than do credit analysts.     

The influence of corporate governance mechanisms on the quality of financial reporting and auditing: Perceptions of auditors and directors in Singapore

This study uses two hypothetical cases to examine the perceptions of auditors and directors in Singapore about corporate governance practices relating to the quality of financial reporting and auditing. In the first case, the strength of the audit committee, the existence of an internal audit function and the strength of a corporate code of conduct were manipulated. All three variables were perceived to have some influence on financial reporting and audit quality. However, some interesting differences were found between the perceptions of auditors and directors. Auditors place more weight on the internal audit function, possibly due to their familiarity with the role that internal audit can play in reducing audit risk and enhancing controls. Directors have more confidence in board enforcement of a strong code of conduct, possibly reflecting the view that this encourages staff to adhere to higher ethical standards. In the second case, audit partner rotation, outsourcing of internal audit services and whether the audit firm audited all companies within a group were manipulated. Auditors believed that their ability to resist management pressure was enhanced when they audited all companies within the group. No significant differences were found for the other variables, suggesting that neither group believes that these practices impair audit independence.     

会计师事务所合并与审计定价——基于2003—2009年十起合并案面板数据的研究

会计师事务所合并究竟是会提高还是会降低审计收费,取决于合并后事务所声誉及市场势力提升所带来的审计溢价与规模效应所导致的审计成本降低两方面孰者相对占优。文章以我国2003—2009年间十起事务所合并案为对象,利用其上市公司客户在事务所合并前后各2年的面板数据,检验了事务所合并对审计定价的影响。结果发现,事务所合并后,其审计收费显著提高。对所有事务所客户审计费用的横向比较也印证了上述结论。研究还发现,事务所合并后第一年审计收费的提升较第二年更为明显;就稳定客户数据而言,本土事务所之间合并对审计定价的影响不如涉及"四大"的合并显著;此外,新设合并与吸收合并对审计定价的影响没有显著差异。     

Audit fee determinants and auditor premiums: evidence from the micro-firm sub-market

Despite the growing literature on the market for audit services, to date no study has examined the determinants of audit fees for the smallest auditees in the market. This study therefore provides some new theory and evidence on the determinants of the audit fees of micro-firms operating in the UK manufacturing sector. A key finding of the study is that in the highly competitive market under consideration, independent small auditees willingly paid a premium to be audited by a mid-tier or a (then) Big Six auditor, with the latter commanding the higher premium. It is concluded that these findings are consistent with Big Six (and, to a lesser extent, mid-tier) auditors commanding a brand premium stemming from the (perceived) higher quality audit conducted by large auditors, for which small firms are willing to pay a premium in order to benefit from associated ‘reputational’ and ‘signalling’ effects. The common finding that the explanatory power of audit fee models declines as a function of firm size is also examined. The empirical analysis confirms this effect, but evidence is offered that, rather than resulting from model misspecification, it is likely that audit prices of the smallest auditees are relatively insensitive to variations in corporate size, which may result from lower incremental economies of scale and minimum pricing.

EC Green Paper Proposals and Audit Quality

In order to restore confidence in financial statements the European Commission proposes different measures to enhance audit quality. This paper examines potential effects of selected proposals on audit quality in the light of prior research findings. It concludes that an increased emphasis on substantive audit procedures may not be beneficial and that joint audits potentially improve competition and audit quality, but might increase audit fees. An appointment by a third party would strengthen auditor independence. The overall impact of a mandatory rotation of audit firms is unclear due to opposite effects on auditor competence and auditor independence. The provision of non-audit services might affect independence in appearance negatively. However, a total ban would not be necessary. Finally, a limit to the proportion of fees an audit firm can receive from a single client as well as a capping of non-audit fees seem to be desirable.     

Audit market structure,fees and choice in a period of structural change: Evidence from the UK – 1998–2003

This paper presents evidence on audit market concentration and auditor fee levels in the UK market in the crucial period of structural change following the PricewaterhouseCoopers’ (PwC) merger and encompassing Andersen’s demise (1998–2003). Given the current interest in auditor choice, analysis is also undertaken at the individual audit firm level and by industry sector. There is evidence of significant upward pressure on audit fees since 2001 but only for smaller auditees. Audit fee income for top tier auditors (Big 5/4) did not change significantly while the number of auditees fell significantly, consistent with a move towards larger, less risky, clients. A decomposition analysis of the aggregate Big 5/4 concentration ratio changes over the period identifies the impact of four distinct consumer-based reasons for change: leavers; net joiners; non-par auditor switches; and (only for the audit fees measure) audit fee changes. Andersen’s demise markedly reduced the level of inequality among the top tier firms but PwC retained its position as a ‘dominant firm’. On switching to the new auditor, former Andersen clients experienced an initial audit fee rise broadly in line with inflation, with no evidence of fee premia or discounting. They also reported significantly lower NAS fees, consistent with audit firms and auditees responding to public concerns about perceptions of auditor independence. There is no general evidence of knowledge spillover effects or cross-subsidisation of the audit fee by NAS. The combined findings provide no evidence to indicate that recent structural changes have resulted in anticompetitive pricing; the key concerns remain the lack of audit firm choice and issues concerning the governance and accountability of audit firms.     

The effect of audit firm size on audit prices: A study of the Australian Market

The effect of audit firm size on prizes is a complex function of competition in the market for audit services, product differentiation, and scale economics to large firms. In this study, a competitive market is supported in Australia with product differentiation to Bif Eight accounting firms. Specially, Big Eight accounting firms have significantly higher audit prices than non-Big Eight firms. This results holds for ‘large’ and ‘small’ auditees. A test is also made of price cutting in the Australian market. Price cutting is defined as lower initial audit fees than continuing engagement fees for a comparable audit. Test results do not evidence price-cutting behavior by accounting firms. There is in fact weak evidence that initial audit fees are higher than continuing engagement fee levels. Higher initial fees suggest that accounting firms may recover at least some of the audit start-up costs immediately.
