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.     

Auditor liability and excess cash holdings: Evidence from audit fees of foreign incorporated firms

Auditors of foreign cross-listed firms face liability arising from the nature of the institutional monitoring framework of legal claims that can potentially be brought against the auditor in both the home country and the US. This paper is the first to document the relationship between auditor liability and auditor pricing of excess cash holdings for foreign firms cross-listed in the US. Our findings indicate that auditors demand a fee premium for foreign incorporated clients with greater excess cash holdings, consistent with auditors recognizing the potential for legal exposure to agency conflict arising from foreign listed US traded clients. Furthermore, we examine aspects of foreign capital market protections, such as disclosure requirements, the strength of legal enforcement, and the strength of shareholder rights to better understand auditor perception of the liability they incur due to the agency costs associated with excess cash holdings. We find that there is a significant positive association between audit fees and excess cash holdings for firms where the country of incorporation permits greater liability of auditors in criminal and civil litigation. In addition, auditors assign higher audit fees to firms holding greater excess cash incorporated in countries with greater required accounting disclosure, stronger legal enforcement and stronger shareholder rights.     

Non-audit services provided to audit clients,independence of mind and independence in appearance: latest evidence from large UK listed companies

This paper investigates whether the provision of non-audit services (NAS) to audit clients impairs auditor independence of mind and independence in appearance. The main contributions of this paper are in terms of its timeliness with respect to regulatory changes, the simultaneous examination of both forms of auditor independence and the methodological innovation whereby it uses a variable derived from the level of abnormal audit fees as a moderating variable in order to capture the direct impact of the NAS fee level on auditor independence as well as how its influence is moderated by the level of unexpected audit fees. Our results indicate that auditor independence of mind is compromised by the size of NAS fees, particularly for clients who pay below the level of expected audit fee. The stock market perceives that auditor independence is compromised by NAS fees but, at the same time, additional tests indicate that there are benefits that accrue from NAS and, in particular, the relation between return and non-discretionary net income is increasing in NAS fees. The balance of evidence suggests that the European Union is correct in undertaking some reform of the auditing market.     

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.     

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.     

Evidence on the Joint Determination of Audit and Non-Audit Fees

In this study we investigate whether the characteristics of clients, auditors, and the auditor‐client relationship simultaneously determine audit and non‐audit fees. As done in prior studies, we maintain that fees proxy for the level of service provided and follow the physical flow of knowledge. Estimating single‐equation models of audit and non‐audit fee models, we confirm prior findings of an association between audit and non‐audit fees. Studies conclude that such evidence is consistent with knowledge spillovers between the two services. However, we document empirically that audit and non‐audit fees are simultaneously determined. Because the data indicate audit and non‐audit fees are jointly determined, we then investigate whether previously documented associations between audit and non‐audit fees are the result of biased estimation induced by using endogenous variables in single‐equation models. In contrast to results from single‐equation estimations, we find no association between audit and non‐audit fees using a simultaneous specification of the fee system, suggesting that single‐equation estimations suffer from simultaneous‐equations bias. In sum, the findings are not consistent with the existence of economies of scope from the joint performance of audit and non‐audit services after controlling for the joint behavior of audit and non‐audit fees. Given the ongoing debate over the level of allowed non‐audit services by auditors, the argument for the joint provision of audit and non‐audit services is less justified than if joint‐supply benefits had been documented.     

Government ownership,audit firm size and audit pricing: Evidence from China

The present study provides empirical evidence on the impact of government ownership on audit pricing behaviour based on data from Chinese listed companies between 2001 and 2008. Our findings, having controlled for auditor choice, indicate that state-owned enterprises (SOEs) incur significantly lower audit fees than non-SOEs. The results also reveal a significant interaction between the type of SOE (i.e., owned by central vs. local government) and audit firm size, which also affects audit fees. More specifically, large auditors tend to charge the central-SOEs lower audit fees than local-SOEs (province, city and county), while small auditors charge central-SOEs higher fees than local-SOEs. We explore a political economy rationale from a supply-side perspective in explaining the results.     

Pro forma disclosures,audit fees,and auditor resignations

The disclosure of non-GAAP (pro forma) earnings numbers by managers in the post-SOX era continues to attract attention from regulators, media, and researchers. However, there is limited empirical evidence on how auditors view clients that emphasize pro forma earnings over GAAP earnings. We study the extent to which audit fees and auditor resignations are associated with opportunistic non-GAAP disclosures. We find that during the pre-SOX period, optimistic pro forma differences, measured using either IBES actual earnings or hand-collected pro forma earnings, are associated with higher audit fees and a higher likelihood of auditor resignations. Additional results indicate that auditors seem to be more concerned with non-GAAP earnings disclosures in the post-SOX period.     

Audit firm tenure and financial restatements: An analysis of industry specialization and fee effects

This study investigates the relation between audit firm tenure and clients’ financial restatements. Specifically, we extend the audit tenure literature by assessing restatement-based reporting failures using dimensions of auditor expertise and independence previously assumed to underlie short and long audit tenure problems. Short tenure expertise and independence effects are hypothesized using audit firm industry specialization and audit fees as proxies. Long tenure independence effects are hypothesized using nonaudit fees as a proxy. Using matched-sample logistic regression and 382 companies with and without financial restatements during 2000–2004, the results support prior findings by indicating a negative relation between the length of the auditor–client relationship and the likelihood of restatement. For short tenure engagements, we find that auditor industry specialization and audit fees are negatively related to the likelihood of restatement. This result is consistent with concerns about reduced audit quality due to a lack of client-specific knowledge and low audit fees on new audit engagements. Alternatively, the long tenure results indicate an insignificant relation between nonaudit fees and the likelihood of restatement. This finding contradicts independence concerns about nonaudit fees paid to entrenched auditors.     

The Provision of Other Services by Auditors: Independence and Pricing Issues

This research has three objectives: to identify the extent and level of other services provided by incumbent auditors in the Australian business environment; to examine pricing issues by investigating the relationship between fees for other services and audit fees; and to address the question of independence by (a) identifying whether the incidence of audit qualification is related to the level of other services purchased and (b) investigating whether there is a relationship between audit tenure and the level of other services provided. Information on audit fees, fees for other services, size, audit qualifications, industry and auditor (Big 8(6)/Non-Big 8(6)) was obtained from publicly available information for the majority of the top 500 Australian companies listed on the Australian stock exchange between 1986–1990. This study provides evidence that an increasing number of clients are purchasing other services from their auditor. A significant positive relationship between fees paid for other services and audit fees was also identified. No relationship was identified between the level of other services and the type of audit report issued or audit tenure, supporting the view that audit independence is not compromised by provision of the other services.     

The association between municipal disclosure practices and audit quality

This study examines the impact of two proxies for audit quality on a model of public sector disclosure for a sample of municipal governments. I argue that more complete disclosures enhance the reputation of an independent auditing firm and that independent auditors, seeking to maintain a reputation of higher quality, positively influence the level of financial disclosures appearing in their clients' financial statements.Specifically, a variable indicating the presence of a (then) Big Eight auditor and regression residuals from a model of audit fees were used as surrogates of audit quality. These were included in a model designed to explain variation in an index representing financial disclosures required under generally accepted accounting principles for local governments. The results provide evidence in support of the hypothesized relationship between audit quality and disclosure.     

Public Disclosure of Audit Fees and Bargaining Power between the Client and Auditor: Evidence from China

Before the public disclosure of audit fees was mandated, it was unlikely for an audit client to have accurate information about how much other companies were charged by their auditors. Public fee disclosure decreases the cost of auditees' access to audit fee information for the auditor's portfolio of clients and is thus likely to increase the relative bargaining power of auditees over auditors when they negotiate audit fees. Using both proprietary and public audit fee data before and after public fee disclosure was mandated in China, we provide evidence consistent with the preceding conjecture. We find that public fee disclosure reinforces the magnitude of audit fee decreases for overcharged clients and weakens auditors' ability to raise audit fees for undercharged clients. These findings suggest the existence of unintended consequences of public fee disclosure regulation, the original rationale of which was a concern about audit pricing practices that could undermine auditor independence.     

The pricing of audit and non-audit services in a regulated environment: a longitudinal study of the UK life insurance industry

This paper studies the relationship between audit and non-audit service fees paid to the statutory auditor by UK life insurance firms, utilising an extensive panel-data sample set for the period 1999–2009. Consistent with a knowledge spillover (impairment of independence) hypothesis, we predict and find that audit fees are positively (negatively) associated with actuarial (tax service) fees. Additionally, our results indicate that regulatory changes enforced after 2004 deterred UK life insurance firms from purchasing non-audit services that are perceived to impair auditor independence. Finally, we find evidence concerning the inter-temporal determination of audit fees.     

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.     

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.     

Consequences of adopting an expanded auditor’s report in the United Kingdom

The United Kingdom has recently required an expanded auditor’s report for large public companies. We investigate whether this requirement is associated with an increase in the decision usefulness of the auditor’s report and whether it has indirect consequences on audit fees and quality. Our analyses cover four years surrounding the changes, including companies that transitioned to the new regime and companies that continued issuing the previous report’s format. We do not find evidence that the regulatory change significantly affected investors’ reaction to the release of auditors’ reports, audit fees, or audit quality. Furthermore, we do not find that variation in the expanded reports’ content has affected these outcomes. Although companies with long reports pay comparatively higher fees, the mere increase in disclosure does not affect audit fees or quality. Collectively, our evidence is consistent with the expanded auditor’s report providing little incremental information to investors.     

How do auditors view managers’ voluntary disclosure strategy? The effect of earnings guidance on audit fees

The objective of this study is to examine the relation between attributes of earnings forecasts issued by managers and audit fees. Although there is an extensive literature on managers’ disclosure of earnings forecasts, there is a paucity of research on how auditors incorporate information from these voluntary disclosures. We find that the issuance of an annual or quarterly management earnings forecast in the prior period is positively associated with the current period audit fees. Our results indicate that on average, audit fees are higher by about 7% for firm-years associated with an annual forecast. Among the firms that issue earnings forecasts, we find no association between audit fees and likelihood of updating a previously issued earnings forecast, indicating that auditors do not view such behavior negatively. Further, we find audit fees to be positively associated with the error and the bias (or optimism) in the forecasts for annual forecasts but not for quarterly forecasts. Overall, these results suggest that management’s forecast behavior captures higher business risk for the auditor via greater risk of earnings management or litigation risk.     

Referral as a determining factor for changing auditors in the Belgian auditing market: An empirical study

Traditional research on auditor choice and auditor switching focuses on company and audit (or) characteristics such as size and reputation, level of fees, or audit opinion. These studies seek causal relationship between changes in these characteristics and changes in auditor. This article claims that the conclusions of existing research have limited application to smaller companies in a small open economy like Belgium. We see a need to supplement the research model to reflect the fact that the decision to choose or switch auditors in subsidiary companies often occurs at the parent level and is determined by group characteristics rather than local characteristics of the subsidiary. In this article, we show that “referral,” the situation whereby the subsidiary—encouraged by the parent company—appoints the same auditor as the parent company, must be considered as an explanatory variable to understand audit-switching behavior in Belgium.     

The Effect of Corporate Status on External Audit Fees: Evidence From the UK

Abstract:  This paper simultaneously examines, for the first time, the determinants of external audit fees of UK companies drawn from the quoted sector (Main Market, the Alternative Investment Market and Ofex), and the unquoted sector (public and private limited companies). The paper also provides new evidence on the effects of corporate failure and the persistence of the big four and mid-tier auditor premiums across the public and private corporate sectors. After controlling for firm size, audit risk and complexity, we find that quoted and unquoted public limited companies have significantly higher audit fees than their private limited counterparts. Our estimates imply that relative premiums for market/corporate form are as follows: Main Market over AIM, 6.8%; AIM over Ofex, 19.5%; Ofex over unquoted plc, 15.5%; and unquoted plc over private, 16.7%. However, despite indications in prior US research to the contrary, we find no evidence that insolvent firms that failed were charged higher audit fees in the year preceding failure. A positive relationship is also found between audit and consultancy fees – a result that persists using an instrumental variables approach to control for endogeneity.     

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.
