Client influence and auditor independence revisited: Evidence from auditor resignations

Financial scandals such as the Enron-Andersen debacle provoke concerns that auditors lack independence when faced with influential clients. Unlike previous studies that examine whether client influence affects audit quality on ongoing engagements (providing mixed results), we investigate whether client influence (which engenders “independence risk”) at the audit-office level affects auditor resignations from high engagement-risk clients. We construct summary measures of engagement risk, using client disclosures on Form 8-K filings, potential risk factors (e.g., litigation risk), and auditor action (e.g., issuance of a going concern opinion) on the previous year’s financial statements. Focusing on risky clients, we find that auditors are more likely on average to resign from influential clients, and this positive association holds for auditors that are less likely to have mechanisms in place to mitigate independence risk. Also, importantly, influential clients are prevalent across the spectrum of client size, and the positive association between client influence and auditor resignations holds for both large and small clients.     

Legal systems and auditor independence

This paper examines whether an appropriate legal system, which is a combination of a legal regime and a damage apportionment rule, effectively enhances auditor independence. Economic and psychological hypotheses derived from a one-period game model in which the auditor may commit either a technical audit failure (resulting from the auditor’s inability to detect true output given a lack of audit effort) or an independence audit failure (resulting from the auditor’s intentional misreporting on false output) are tested. Three major findings are documented. First, auditor independence affects firm investment, which in turn affects audit effort. Under this strategic dependence, no single legal system can provoke audit effort, improve auditor independence, and encourage firm investment simultaneously. To enhance auditor independence and motivate investment, a legal system consisting of both a strict regime and a proportionate rule is preferred. Second, the strict regime induces more auditor independence than the negligence regime, while the proportionate rule induces higher audit effort than the joint-and-several rule. Finally, auditors’ moral reasoning and penalty for misreporting are both positively associated with their independence. In addition, the effect of moral reasoning on auditor independence diminishes as the level of penalty increases. These two results hold only when the legal systems that auditors face are considered.     

UK investors’ perceptions of auditor independence

The auditor’s role in society is that of validating the truth and fairness of financial statements. If owners of organisations doubt the auditor’s independence, financial statements will lack credibility. This questionnaire-based study investigated how investors perceive three potentially independence-impairing auditor–client relationships: the joint provision of audit and non-audit services, an audit firm’s economic dependence upon a client and long-term relationships between auditor and client. The objective was to determine whether, after a series of high-profile corporate collapses, owners retain faith in the integrity of the auditor. The results suggest that economic dependence and the provision of non-audit services are perceived as greater threats to auditor independence than long-term relationships between the auditor and client.     

Perceptions of auditor independence: Its perceived effect on the loan and investment decisions of German financial statement users

Recent research in the United States and the United Kingdom investigated the effect of the perceived independece of auditors on the financial decisions of financial statement users. This paper is an extension of that research, reporting the results of a mail survey of two groups of German users of financial statements audited by German auditors. The survey was undertaken to investigate the user' perceptions of auditors' independence for a number of auditor-client relationships and to determine how those perceptions would affect their financial decisions.     

审计委员会与外部审计独立性

本文首先从完全信息动态博弈的视角出发,推导得出,强化外部审计独立性是审计委员会的基本职能之一.然而,接下来的实证检验结果却与前述的理论预期相悖,即实证检验结果表明,我国上市公司审计委员会制度在实际运行中,并不具有强化外部审计独立性的功能.接下来的分析表明,由于缺乏"独立人"的资格,导致我国审计委员会很难打破原有的均衡,从而很难强化外部审计独立性.     

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.     

Consulting revenue sharing,auditor effort and independence,and the regulation of auditor compensation

The joint provision of audit and non-audit services by audit firms to their audit clients has posed a threat to auditor independence. To mitigate the independence problem, the US Securities and Exchange Commission (SEC) issued a regulation (SEC, 2003) that prohibits audit partners from receiving compensation for the sale of non-audit services to their audit clients. This study examines the effects of this regulatory change on the effort and reporting decisions of audit partners. We show that partners in an audit firm strategically change the firm’s liability-sharing rule. As a consequence, the regulation restores truthful reporting but has an undesirable negative effect on audit effort. The effect of the regulation on the welfare of the economy (defined as the total payoff to both audit firms and their clients) hinges on the tradeoff between the benefit of the regulation, which is derived from the inducement of truthful reporting, and the cost of the regulation, which results from less diligent audit work. We show that the regulation is more likely to increase the welfare in a strong legal regime (where the legal liability cost of auditor litigation is high) than in a weak legal regime.     

Educational interventions for teaching the new auditor independence rules

The Sarbanes-Oxley Act of 2002 brought sweeping changes to the accounting profession. One important mandate was for the US Securities and Exchange Commission (SEC) to strengthen the rules of auditor independence. To meet its legal responsibility, the SEC issued Final Rule No. 68 [United States Securities and Exchange Commission (USSEC) (2003). Final Rule 68: Strengthening the commission’s requirements regarding auditor independence. Washington, DC: Government Printing Office [Issue Date: January 28, 2003 (www.sec.gov/rules/final/33-8183.htm and Retrieval Date: January 25, 2004)]], thereby adopting new independence rules for auditors of public companies.     

U.S. Audit partner identification and auditor reporting

After a lengthy and protracted debate, the Public Company Accounting Oversight Board (PCAOB) adopted new rules requiring disclosure of the engagement partner’s name and information about other accounting firms on the new PCAOB Form AP, Auditor Reporting of Certain Audit Participants. We investigate the impact of this regulation on auditor behavior in the context of the auditor’s going concern report modification propensity. We document an increase in the propensity to issue a going concern report modification in the disclosure regime, accompanied by a corresponding increase in the Type I (‘false positives’) error rate. Thus, an unintended consequence of Rule 3211 is the potential reduction in the audit report's informativeness. Conceivably, a more significant repercussion is that going concern modifications can hasten bankruptcy for firms since financial institutions may be reluctant to lend money to firms with modified audit reports. An unjustified increase in the going concern modification rate as evinced in our paper may make U.S. capital markets potentially less attractive to young, upstart, albeit financially-distressed, companies.     

Non-audit service and auditor independence: an examination of the Procomp effect

This paper examines whether non-audit service provision impairs auditor independence, and whether the degree of auditor independence in Taiwan changed in the wake of the 2004 Procomp scandal. The auditors involved in the Procomp affair were suspended from practice for 2 years and were sued, and we posit that these unprecedented sanctions and litigation affected subsequent auditor behavior. Considering the measurement errors involved in discretionary accruals, we propose an alternative analytic approach in which the dependent variable in the regression analysis is the difference between audited earnings and forecast earnings, scaled by total assets, and the primary independent variable is the non-audit fees ratio. After controlling for the effects of financial leverage, operating and market performance, industry, company size, audit firm size, management forecast error, and management attempts to manipulate earnings, regression analysis indicates that the coefficient for non-audit fees ratio is negative and significant in 2003 but not in 2004. Using non-audit fees instead of non-audit fees ratio to conduct the regression analysis yields similar results. This finding is consistent with the notion that auditors make a trade-off between gaining service fees and avoiding litigation and reputation loss. Limitations and policy implications are also offered.

Takeover premiums and the perception of auditor independence and reputation

This study investigates if there is a positive association between takeover premiums and the bidder’s perception of target firm auditor reputation and independence. Using auditor size as a proxy for auditor reputation, the results indicate that in hostile takeovers target shareholders receive a higher takeover premium when a Big 4 auditor audits the target firm prior to the takeover. This result is only significant, however, in the period prior to the highly publicised audit failures. The impact of perceived auditor independence on takeover premiums is studied using the levels and size of non-audit service (NAS) fees provided by the target firm auditor. Using three proxies for auditor independence, the results show no association between perceived auditor independence and takeover premiums. This finding is robust to partitioning the sample by auditor size, takeover hostility and splitting the sample into takeovers pre- and post- the corporate scandals that occurred in 2002.     

Audit and non-audit fees and capital market perceptions of auditor independence

This study provides evidence on whether auditor independence-in-appearance, proxied by earnings response coefficients, is related to the non-audit fee ratio (non-audit to total fees from a client) or client importance (total fees from a client as a percentage of the total revenues of the audit firm). The results from large samples over the period 2001–2006 show, contrary to popular belief and the findings of some prior studies, that there is no evidence of a relation between perceived auditor independence and the non-audit fee ratio. However, perceived auditor independence is negatively associated with client importance, consistent with the economic theory of auditing. Our paper adds to the literature by examining the relative importance of non-audit fee ratios and client importance as determinants of independence-in-appearance.     

The value relevance of major media advertising expenditures: Some U.K. evidence

This study examines whether ACNielsen MEAL major media advertising expenditure measures, that are publicly available at a cost, have value relevance. Our results suggest that these advertising-expenditure measures are positively associated with market value. We also find little difference in the value relevance of these expenditures among different sizes of firms. Value relevance is found to be present only for nonmanufacturing firms. This suggests that the costly information provided by ACNielsen MEAL surveys may be potentially useful to market participants in valuing firms, at least for nonmanufacturing firms.     

Audit committee quality,auditor independence,and internal control weaknesses

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.     

The effects of audit firm rotation on perceived auditor independence and audit quality

Our study explores loan officers’ perceptions of auditors’ independence and audit quality under three experimental audit firm rotation scenarios. We use a case experiment with a between-subjects design to determine whether rotation of the audit firm impacts financial statement users’ perceptions of auditor’s independence and quality. Findings based on 212 useable responses indicate that loan officers do perceive an increase in independence when the company follows an audit firm rotation policy. However, the length of auditor tenure within rotation fails to significantly change loan officers’ perceptions of independence. Findings also indicate that neither the presence of a rotation policy nor the length of the auditor tenure within rotation significantly influences the loan officers’ perceptions of audit quality.     

Long-horizon abnormal performance following rights issues and placings: Additional evidence from the U.K. market

We revisit the long-horizon abnormal performance of U.K. firms following rights issues and placings over the period 1989-1997. We make the following contributions relative to prior research. First, we use, as far as we are aware, a more comprehensive data set of rights issues and placings than hitherto studied for the U.K. market. We thus exploit the fact that issuing new equity predominantly through rights issues is a feature of the U.K. equity market that differs from the U.S. and other markets, where public offers dominate seasoned equity issues. Second, we study both the pre- and post-offer long-horizon performance, complementing previous research that focuses only on announcement-day wealth effects. Third, we apply various metrics and revisit the evidence of long-horizon post-offer underperformance reported in previous research. We find, however, little evidence of long-horizon post-offer underperformance for U.K. firms following issues of equity through rights issues or by placings.     

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.
