Non-audit Services and Auditor Independence: New Zealand Evidence

Abstract:  This paper examines evidence in New Zealand about whether auditors providing more non-audit services are less independent. Three sets of tests are used to address the issue. The first examines whether there is a relation between non-audit fees and audit fees, the second examines whether there is a relation between non-audit fees and audit report qualification or modification, and the third examines whether there is a relation between non-audit fees and stability of audit tenure. The results suggest a potential for the impairment of auditor independence in appearance when auditors provide non-audit services but no evidence of any impact on independence of mind.     

New development: Local public audit—the changing landscape

This article considers the implications for local public audit of the abolition of the Audit Commission and its audit practice (District Audit). The audit regime of NHS foundation trusts, where the Audit Commission is not responsible for auditor appointments or their oversight, is investigated to provide insights for the future of local public audit.     

AUDIT FEES AND AUDITOR CHANGE; AN INVESTIGATION OF THE PERSISTENCE OF FEE REDUCTION BY TYPE OF CHANGE

Despite concern expressed over 'low-balling' or competitive price reduction in the market for audit services, the only empirical investigation of the relationship between initial audit fees, fee recovery and auditor change which has been carried out is by Simon and Francis (1988) using US cross-sectional data, although Pong and Whittington (1994, forthcoming) examine the impact on first year fees. We investigate the impact of auditor change on cross-sectional UK data for 1991 with the aim of discovering whether there is any evidence of price cutting and subsequent price recovery in a European, rather than a US context. We find that there is evidence of such a phenomenon, and investigate further to see whether this effect is robust with respect to the definition used of 'auditor change', and whether the effect varies according to whether the old auditor was a 'Big Six' or 'non-Big Six' firm. We find that the largest reductions (controlling for auditor size) are experienced by firms changing to 'Big Six' firms. We further show that involuntary changes (by auditor acquisition) are associated with positive (although statistically insignificant) increases in fees, whereasvoluntary changesare associated with negative (andsignificant) feereductions. These effects are shown to be robust with respect to model specification. This suggests that fee reductions cannot be ascribed to economies of scale or scope, but is consistent with a 'low-balling' model of behaviour.     

Auditor independence, executive pay and firm performance

This paper investigates whether compensation committees actively intervene to adjust accounting performance‐based incentive schemes for the real, or perceived, reduced earnings credibility signalled by the purchase of non‐audit services. Using a nonlinear, two‐stage least‐squares method that accounts for the simultaneity of executive pay, firm performance and non‐audit fees, we find a significant negative relationship between non‐audit fees and the sensitivity of chief executive officer (CEO) pay to firm performance. Point estimates suggest that the reduced weight applied to accounting performance lowers the incentive component of executive pay between roughly 5 and 8 per cent for the CEO of the ‘average firm’.     

审计师变更与审计质量:一个理论分析

本文通过建立股东、管理层和审计师三方参与的两委托人-单代理人博弈模型,研究了固定审计费用下不同审计师变更方式对审计质量的影响。研究结果表明,审计师强制性单期变更与审计师强制性定期变更下,审计师与管理层之间的合谋将导致严重的财务舞弊;而在审计师自愿性变更下,股东可以利用解聘现任审计师这一威胁来阻止审计师和管理层之间的合谋,使得审计师和管理层的最优策略均为真实披露公司的盈余信息,并发表标准无保留审计意见。     

Public Audit: A Clarification of CIPFA's views – A Reply

In this article I reject Martin Evans' accusation that I seriously misrepresented CIPFA when citing CIPFA's submission to the Nolan Committee in my 1996 FAM article. CIPFA's argument regarding auditor independence is presented as a difference between two conceptual models – the private sector and public sector models of audit. I argue that however Evans tries to present CIPFA's position, any concerns relate to differences of practice, not concept. Whilst it is understandable that CIPFA would wish to present these differences as relating to conceptual frameworks, the argument does not stand up to scrutiny.     

Future Events—A Conceptual Study of their Significance for Recognition and Measurement A Review Article

A number of research papers present evidence of fee premiums paid to specialist auditors. In this paper, we explore for listed and unlisted New Zealand firms not only the question of whether such premiums exist, but perhaps more importantly why they exist. We find evidence of fee premiums for auditor specialisation defined at the city level but not at the national level. We extend testing to examine the issue of self-selection of auditors by clients; we examine several different industry classification schemes and a number of different specialisation measures; and we consider the issue of portfolio specialists. We find from these additional tests that self-selection does not account for the existence of specialisation premiums; various alternative classification schemes all result in premiums at the city level; and portfolio specialists also earn fee premiums when portfolio specialisation is measured at the city level. We find that these specialist premiums apply most consistently to larger client firms and to low-risk firms. We consider various explanations and conclude that this result is consistent with non-specialist auditors providing discounts to attract desirable clients. Desirable clients – those that are large or low risk – are not able to negotiate fees as successfully with auditors who have differentiated themselves via industry specialisation.     

公司避税活动对会计师事务所变更的影响

利用我国A股非金融类上市公司2009~2017年数据,同时用会计-税收差异和经应计项目调整的会计-税收差异两个指标度量公司的税收激进度,进而检验客户税收激进度对审计师变更的影响,结果发现,在控制了盈余管理等因素后,税收激进度与会计师事务所变更的可能性之间呈显著正向关系,这表明,审计师会将客户过于激进的避税活动视为高风险的标志,从而提高审计师变更的可能性。进一步研究发现,公司内部控制质量和产权性质可以缓解税收激进度对审计师变更的影响。这一研究可以进一步丰富审计师对客户避税活动的反应的相关文献,并可以从审计的角度拓展公司避税行为后果的文献。     

Public Audit: A Comment and a Clarification of CIPFA's Views

This article aims to clarify CIPFA's views on the arrangements for 'public audit', as reflected in its submissions to the Nolan Committee and the subsequent Cabinet Office/Treasury Review of external audit in the public services. In particular, it attempts to correct perceived misapprehensions about CIPFA's attitude to the role of the private audit firms in public sector audit.     

The Market for External Audit Services in the Public Sector: An Empirical Analysis of NHS Trusts

This study investigates the market for audit services in the UK National Health Service (NHS). The market has a number of interesting features, including the presence of the Audit Commission as a regulator, appointer and provider of audit services. Following a theoretical overview of audit pricing in the NHS, evidence is provided on the behaviour of private sector auditors in an environment where audit risk characteristics differ from the private sector. The research also investigates, for the first time in the public sector, the relationship between audit fees and non–audit (consultancy) fees. Comparisons are also drawn between audit fees in the public and private sectors in an analysis of audit fees by industry. Despite some key similarities, the study shows that a number of differences exist between private and public sector audit fee models. In particular, we find no evidence of Big 6 (or mid–tier) auditor premiums, but we do find a significant negative relationship between audit and consultancy fees providing support for the 'knowledge spill–over' hypothesis. In addition, the fees charged to trusts appear significantly lower than their private sector counterparts, despite trust auditors having additional duties to perform. Possible explanations for this finding are offered in the paper.     

The impact of revolving door practice and policy on nonprofessional investors’ perceptions of auditor independence

This study investigates whether an ex-auditor’s employment with an audit client impairs nonprofessional investors’ perceptions of auditor independence, and whether the strength of the US revolving door policy improves their perceptions of auditor independence. Despite nonprofessional investors owning over one-third of the US equity holdings, the literature has not examined how revolving door policy impacts their perceptions of auditor independence. Two between-subjects experiments examine these issues. The first experiment finds that investors perceive the ex-auditor’s integrity to be significant in explaining the firm’s decision to manage earnings, irrespective of the firm’s previous working relationship with the ex-auditor. The results from experiment two indicate that strengthening the revolving door policy above that of the American Institute of Certified Public Accountants’ policy does not improve perceptions of auditor independence. Academics may be interested in triangulating the independence ‘in appearance’ results of this study to the independence ‘in fact’ results of other studies, since the Securities and Exchange Commission asserts that both facets of independence are equally important. The results may also be of interest to academics and practitioners, as prior research suggests that restricting auditors’ moves to management positions with the client impairs firms’ abilities to hire quality auditors.     

The Impact of Managing Director Changes and Financial Distress on Audit Qualification and Auditor Switching

Abstract:   This study examines the interactive effects of change in managing director/chief executive officer (MD) and financial distress together with five control variables (type of audit firm; audit fees; gearing; time; and company size) on first, audit opinion and secondly on auditor switching. Based on a sample of 297 UK listed companies between 1987 and 2001, we find that companies that are financially distressed and change their MD are most likely to receive a qualified audit report, ceteris paribus . In addition, we find evidence of both familiarity and intimidation threats and that the probability of a switch increases with the severity of qualification.     

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.     

审计委员会特征与会计师事务所变更的经验研究

本文以会计师事务所变更为视角,探讨具备怎样特征的审计委员会才能有效履行其职责。研究表明:审计委员会的独立性和专业性与会计师事务所变更显著负相关;审计委员会的开会次数与会计师事务所变更没有显著关系,说明审计委员会的存在有助于减少会计师事务所变更。但在对会计师事务所变更的进一步研究中,我们并没有发现会计师事务所变是为了追求更高审计质量的进一步证据,也说明审计委员会对会计师事务所变更的影响仍然有限。这些研究结论为完善我国审计委员会制度提供了经验证据。
