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.

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.     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.     

The influence of jurors' perceptions of auditor tenure on blame

This study investigates whether jurors' judgments of auditor blameworthiness are influenced by the length of an auditor's tenure with a client. We use an experiment to determine whether tenure affects juror perceptions of an auditor's competence and independence. We then examine whether these perceptions influence the attribution of blame. Results, consistent with both sides of the mandatory auditor rotation debate, indicate that tenure has a positive impact on perceptions of competence and a negative impact on perceptions of independence. Further, as juror perceptions of the auditor's competence and independence decrease, attributions of blame increase. These results have implications for auditor tenure research as well as for auditors involved in litigation. By utilizing structural equation analysis, we find that the effects of auditor tenure on perceptions of audit quality are complex. Perceptions of both competence and independence are significantly related to extended tenure; however, these perceptions independently affect the assignment of blame. While longer tenure improves perceptions of competence and lessens blame, it decreases perceptions of independence resulting in greater blame. From a litigation perspective, the auditor's tenure with a client is a double-edged sword that must be addressed strategically in court.     

Non-audit services, auditor quality and the value relevance of earnings

This paper tests the hypothesis that there is an inverse relation between non‐audit services (NAS) provided by a firm auditor and the value relevance of earnings (measured as the earnings response coefficient) and that this relation is weaker for firms with Big 6 auditors. The hypothesis is based on anecdotal evidence and previous research that suggests that the provision of NAS by the external auditor is likely to adversely affect investors’ perceptions of the credibility of financial reports, and that Big 6 auditors, because of reputational capital and litigation costs, are likely to mitigate the adverse effects of NAS. Results using 840 firm‐year observations of Australian companies document a statistically significant inverse relationship between NAS and the value relevance of earnings, and this inverse relationship is weaker for Big 6 auditors, therefore supporting the hypothesis.     

Acquirers’ abnormal returns and the non-Big 4 auditor clientele effect

I analyze the effect of auditor choice on acquirers’ values around merger announcements and the factors affecting the interaction between auditor size and the market reaction to merger announcements. I find that acquirers audited by non-Big 4 accounting firms outperform those audited by Big 4 firms. This effect is more pronounced when the targets are privately held and when the likelihood of the auditors playing a prominent advisory role increases. While the largest auditing firms are usually assumed to offer superior services, the study suggests that smaller firms have a comparative advantage in assisting their clients in merger transactions.     

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.     

Earnings quality: Some evidence on the role of auditor tenure and auditors’ industry expertise

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.     

Effect of audit report disclosure on auditor litigation risk

Internationally, the escalating number of cases levelled against auditors and the costs of defending such actions has led to the auditing profession calling for measures to reduce their liability burden. Relatively few measures have been taken by the auditing profession by way of adapting the disclosure contained in the audit report to mitigate their litigation risk. This study examines whether the issuance of an audit opinion with a going concern related ‘emphasis of matter’ paragraph or work practices disclosure has any effect on potential litigants' likelihood of pursuing litigation against the auditor. An analysis of 69 responses from advanced law students and 18 practitioners working in corporate liquidation demonstrate that a modified (but not qualified) audit report effectively acts as a ‘red flag’ and reduces potential litigants' propensity to initiate litigation. However, work practices disclosure did not significantly alter potential litigants' inclination to recommend litigation. Despite this finding, respondents (particularly liquidators) indicated that work practices disclosure was an important factor in their litigation decision. These results suggest that further investigation into how to effectively disclose the work done on audit and assurance engagements is needed. This has implications for standard setters and the auditing profession, especially considering recent changes in the disclosure contained in audit and assurance reports.     

How individual auditor characteristics impact the likelihood of audit failure: Evidence from China

Audit failure imposes a severe loss on investors and damages market participants' confidence in financial reporting quality. This study investigates the impacts of individual auditor characteristics on the likelihood of audit failure. Chinese regulators mandate listed firms to disclose the engagement auditors' identity. Furthermore, the information regarding individual auditor characteristics in China is also publicly available. Utilizing this unique setting, we examine the relationship between individual auditor characteristics and the likelihood of audit failure in China during the period from 2000 to 2009. We document that individual auditors with more auditing experience are less likely associated with audit failure. We also find a weaker negative relationship between auditor education level and audit failure. Our study has important implications for both auditors and regulators by shedding lights on the determinants of audit failure and by providing guidance to the human resource management in audit firms.     

The effect of auditor litigation risk on clients' access to bank debt: Evidence from a quasi-experiment

We exploit staggered state-level shocks to third-party auditor legal liability in the U.S. to test whether auditor litigation risk affects client companies' access to private debt markets. We find that an exogenous increase in auditor litigation risk leads to an increase in both clients' likelihood of receiving bank loans and the average amount of the bank loans that clients receive. In support of our proposed mechanism that auditor litigation risk leads to improvements in clients' audit and financial reporting quality, we find that these same shocks lead to a reduction in accruals, an increase in going-concern opinions, a decrease in restatements, and an improvement in accruals' ability to predict future cash flows. We also find that increased auditor litigation risk leads to an increase in the contractibility of clients’ accounting numbers, as proxied by the use of debt covenants, and a decrease in the cost of borrowing.     

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.     

Government quality,auditor choice and adoption of IFRS: A cross country analysis

We examine the association between country-level government quality and firms' choice of external auditors. Using a cross-sectional sample of 142,193 firm-year observations from 46 countries over 1998–2007, we show that the government quality of a country has a significant positive effect on the likelihood of choosing Big 4 auditors by firms in that country. We also show that firms in countries with strong governments that have adopted IFRS are more likely to choose Big 4 than non-Big 4 auditors. To our knowledge, this is the first study of its kind to provide direct evidence on the role of government quality in firms' choice of external auditors. Choice of a Big 4 auditor may be regarded as a proxy for the demand for high quality financial reporting, and thus the results provide insights for policy makers on the importance of government quality toward improving financial reporting quality in a country.     

Voluntary disclosure of reasons for auditor changes and the capital market reaction to information disclosure

This study examines the association between firm attributes and management’s voluntary disclosure of the reason(s) for auditor changes and evaluates the capital market reaction to information disclosure of the auditor change events accompanied by preexisting red flag and non-red flag issues. We find that managers are more likely to disclose the reason(s) for auditor changes when those changes occurred because of benign business reasons or if the reasons do not indicate the presence of any underlying operating or financial reporting problem. On the other hand, managers are less likely to disclose the reason(s) for auditor changes when those changes are preceded by red-flag situations. Furthermore, auditor changes accompanied by preexisting red-flag situations are viewed negatively by the capital market, implying that the full disclosure of reasons for auditor changes is informative to investors. This observation is supported further by our market-based analyses, which consistently show that auditor changes accompanied by prevailing red flag issues are valued incrementally in the market above and beyond the reportable events (under FRR No. 31) and auditor-initiated changes. The study contributes to the recent policy debate related to mandating the disclosure of the reason(s) for auditor switches. Specifically, the results support the recent debates that the current voluntary disclosure regime results in selective disclosure practices that are likely to contribute to the general lack of transparency with respect to auditor changes.     

CAP Forum on Enron: Professional Insecurity and the Erosion of Accountancy's Jurisdictional Boundaries*

This study examines attitudes about professionalism in accounting shortly before the debacles of Enron and Andersen. Interviews with experienced Canadian chartered accountants (CAs) conducted mostly in late 2000 and early 2001 indicate significant doubts about the notion of auditor independence and a relatively high degree of uncertainty about the future of the profession. Accountants also expressed significant difficulties in describing the basic features of what it means to be a professional accountant. On the basis of these observations, we introduce and detail the construct of “professional insecurity". Relying on Giddens's theoretical developments on the role of trust and systems of expertise in today's society, we reflect on the significance and implications of the professional insecurity of CAs, particularly its impact on accountancy's ability to hold on to its jurisdictional boundaries. Our thesis is that the difficulties that accountants experienced in their day‐today lives in sustaining a coherent sense of self‐identity were particularly stressful to them given people's fundamental need for coherence, and this significantly affected the capacity of their profession to hold jurisdiction.     

Compliance with International Financial Reporting Standards and auditor choice: New evidence on the importance of the statutory audit

We examine the impact of auditor choice on IFRS compliance under the assumption of strict exogeneity of auditor choice. Our results reveal that compliance is positively related to auditor choice after controlling for firm size, profitability, leverage, degree of international diversification, and whether a firm has a U.S. listing or was audited according to International Standards of Auditing. We also find that auditor choice is positively related to firm compliance when controlling for unmeasured, firm-specific effects. The results of our study reinforce the importance of developing institutional mechanisms (e.g., enforcement, auditing, or corporate governance structures) to encourage compliance with IFRS.     

Can clients of economically dependent auditors benefit from voluntary audit firm rotation? An experiment with lenders

This study utilizes a nationwide random selection of 111 lenders in a 2?×?2 between-subjects experiment to determine whether the level of an auditor's economic dependence on a client and type of auditor rotation affect lenders’ independence and reliability perceptions and decisions to lend money to a potential borrower. Previous literature shows that financial statement users use client importance as a measure of audit quality when revenue streams are not equal across clients. This can negatively affect perceptions of independence and financial statement reliability. As United States regulators look for ways to improve audit quality under the current partner rotation mandate, this study explores whether an audited entity that voluntarily adopts a policy of firm rotation can mitigate the negative effects of the auditor's dependence on the client. Findings suggest that lenders view clients of economically dependent auditors (CEDA) as less independent from its auditor and perceive its financials as less reliable than clients without a dependent auditor (non-CEDA). Lenders are less likely to grant a loan to CEDA. However, under firm rotation, there is not only an increase in lenders’ perceptions of reliability of CEDA financials, but also no difference in perceptions of reliability of CEDA and non-CEDA financials.     

Disclosure of fees paid to auditors and the market valuation of earnings surprises

We investigate if the SEC’s recently mandated disclosure of fees for audit and nonaudit services paid by firms to their incumbent auditors affected the market’s perception of auditor independence and earnings quality. Following the initial fee disclosures in 2001, we find that the market valuation of quarterly earnings surprises (earnings response coefficient) was significantly lower for firms with high levels of nonaudit fees than for firms with low levels of such fees. In contrast, in the year prior to the new fee disclosures, there was no reduction in earnings response coefficients for firms that subsequently reported high nonaudit fees. Our evidence suggests that mandated fee disclosures provided new information that was viewed by the market as relevant to appraising auditor independence and earnings quality.

Characteristics of non-audit services and financial restatements in Malaysia

Various types of purchased non-audit services (NAS) and their recurring nature affect the likelihood of financial statement restatements in Malaysia. Based on 953 firm-year observations during the period 2007–2009, evidence of a negative relationship between non-audit fees and financial statement restatements is provided. The purchase of both tax-related and audit-related NAS decreases the likelihood of restatements. Recurring (as opposed to non-recurring) tax-related and audit-related NAS are negatively and significantly related to the likelihood of restatements. These findings support our hypothesis that both types of NAS and their recurrence provide knowledge spillover, which enhances audit and financial reporting quality. When considering institutional settings, we find that politically connected firms are more likely to require financial restatements than non-politically connected firms, while audit committee independence and the purchase of tax-related, recurring tax-related and other NAS decrease this likelihood. The purchase of audit-related and recurring audit-related NAS and non-recurring other NAS decreases the likelihood of restatements for non-politically connected firms.
