SUMMARY: The Public Company Accounting Oversight Board (PCAOB) recently undertook an exploration of the need for mandatory audit firm rotation with its issuance of the Concept Release on Auditor Independence and Auditor Rotation (PCAOB 2011a) The accumulation of evidence from PCAOB inspections of audit engagements over the last eight years has led the Board to consider additional steps to protect auditors’ independence We provide a brief synopsis of these matters based primarily on remarks
by the PCAOB’s chairman, James R Doty (PCAOB 2011b, 2011c) In addition, we include relevant observations from prior academic studies and end with a call for the active participation of stakeholders in this important debate
Keywords: auditor rotation; regulation; inspection
OVERVIEW
On August 16, 2011, the Public Company Accounting Oversight Board issued PCAOB Release No 2011-006, titled Concept Release on Auditor Independence and Auditor Rotation,
‘‘to explore whether there are other approaches that could more systematically insulate auditors from the forces that pull them away from the necessary mindset’’ (PCAOB 2011a) We

Trang 2summarize the PCAOB’s discussion on this issue, based mainly on statements made by James
R Doty, the recently appointed chairman (PCAOB 2011b) While each of the members of the PCAOB has made statements regarding audit firm rotation, we focus on Chairman Doty’s remarks because of his position and role in establishing the agenda of the PCAOB We also intersperse observations from academic findings as well as our opinions that are pertinent to Chairman Doty’s comments We encourage others to participate in this extremely important discussion
CHAIRMAN DOTY’S VIEWS
At the core of the PCAOB’s oversight responsibility for public company audits is its duty to protect the interests of investors and further the public interest in the preparation of informative, accurate, and independent audit reports As such, the PCAOB’s mission is to promote an atmosphere that protects audit quality, to reduce the risks of audit failures in the U.S public securities market, and to promote public trust in both the financial reporting process and the auditing profession Chairman Doty believes that the current arrangement, where the auditor is paid by the auditee, and long associations exist between auditors and clients, particularly large clients, are issues that must be addressed to fulfill the mission of the PCAOB Chairman Doty views audit firm rotation as a potential counterweight to the inherent conflict created by the current structural arrangements (PCAOB 2011b, 2011c)
Chairman Doty believes that the very size, complexity, and systemic risk found in today’s issuer population supports the need for reconsideration of audit firm rotation at this time He notes that the PCAOB has seen evidence of ‘‘auditors marketing themselves to potential clients as ‘a partner in supporting and helping’ the client ‘achieve its goals’’’ (PCAOB 2011b) Chairman Doty does acknowledge, however, that improper auditor conduct would be a problem regardless of the auditor’s tenure In the short term, auditors might please the client to foster a lasting relationship
In the long term, auditors might make concessions to preserve relationships and avoid losing clients Chairman Doty believes it is worth exploring how audit firm rotation could possibly mitigate these incentives (PCAOB 2011b, 2011c)
THE HISTORY OF THE DEBATE
Chairman Doty notes that limiting an audit firm’s tenure is not a new idea and has been discussed by various commentators and organizations for some time (PCAOB 2011b, 2011c) Past public debate has described the basic arguments both for and against mandatory term limits In 1977, the Metcalf Report recommended auditor rotation to remedy independence issues created by long associations between corporations and their auditing firms A year later, the AICPA’s Cohen Commission considered auditor rotation for independence protection and providing a fresh viewpoint In its final report, the Cohen Commission rejected auditor rotation, concluding that such an arrangement is not cost beneficial The question of mandatory rotation surfaced again in 2002 when Congress considered requiring audit firm term limits during the debates that led to the passage of the Sarbanes-Oxley Act The U.S Government Accountability Office (GAO) was charged by Congress to examine issues surrounding auditor rotation The final GAO report issued in 2003 rejected auditor rotation, but noted that the SEC and the PCAOB would need several years to evaluate the effectiveness of the Sarbanes-Oxley reforms That is, the PCAOB would need time to determine whether the reforms are sufficient, or whether further
Trang 3independence measures, such as audit firm rotation, are necessary to protect investors and enhance auditor independence and audit quality (GAO 2003)
PREVIOUS RESEARCH
We would like to note that the GAO’s study surveyed public accounting firms with more than 10 audit clients and Fortune 1000 companies Respondents include 74 public accounting firms, 201 chief financial officers, and 191 audit committee chairs Respondents overwhelmingly opposed mandatory audit firm rotation A fundamental concern with rotation is that it is unduly costly, and the burden of change may be disproportionately high for small audit firms DeFond and Lennox (2011) document that a substantial number of small audit firms have ten or fewer clients, with many having just one audit client The effect of mandatory rotation on such audit firms could be significant By comparison, an audit failure that could have been avoided in
a mandatory rotation regime could have a significant negative impact on investors and creditors
Academic research that directly examines the effect of mandatory audit firm rotation is scant because, except for a handful of countries, such a regulatory regime has not been implemented A notable exception isRuiz-Barbadillo et al (2009), who look at auditor reporting behavior in Spain from 1988–1995, a time period during which audit firm rotation was required in Spain Ruiz-Barbadillo et al (2009) compare the auditor’s propensity to issue a going-concern opinion across periods with and without audit firm rotation The study fails to document any significant differences in the auditor’s reporting behavior While their findings do not provide any evidence to suggest that audit firm rotation improves audit quality, it is important to note that the study examines auditor behavior in a country with different economic and cultural dynamics than those
in the United States
Other academic research investigates the effect of audit firm tenure on various proxies for audit quality Chairman Doty suggests that short tenure may be problematic as audit firms try to build relationships with their clients, and that mandatory rotation likely would be an effective means to curb such behavior (PCAOB 2011b, 2011c) However, we note that a more pressing concern with short tenure may be the auditor’s lack of familiarity with the client Empirical evidence suggests that audit quality is relatively lower in the initial years of an auditor-client relationship Specifically, short tenure is positively associated with audit reporting failures (Geiger and Raghunandan 2002), fraudulent financial reporting (Carcello and Nagy 2004), and reduced earnings quality (Johnson et al 2002) A lack of familiarity may have adverse consequences, which could be exacerbated by instituting mandatory audit firm rotation
Chairman Doty also is concerned with long tenure, suggesting that auditors are incentivized
to avoid being ‘‘the engagement partner that lost the client.’’ He offers anecdotal evidence of auditors conceding to client demands where auditor tenure is very lengthy (PCAOB 2011c) Such evidence is certainly disquieting Yet, academic evidence generally does not suggest that long tenure is detrimental to audit quality (e.g.,Johnson et al 2002; Myers et al 2003; Carcello and Nagy 2004; Knechel and Vanstraelen 2007); however, for a notable exception refer toDavis et al (2009)
PCAOB INSPECTIONS AND ENFORCEMENT
The potential benefits of mandatory rotation are difficult to predict The PCAOB’s inspections, however, suggest that the current regulatory regime provides ample room for improvement After
Trang 4eight years of conducting annual inspections of the largest and smaller domestic and non-U.S firms, inspectors have found hundreds of audit deficiencies where, in many cases, auditors failed
to exercise the required skepticism and accepted less than persuasive evidence.1 Similar concerns have surfaced in the PCAOB’s enforcement program The Board’s efforts to address these problems through inspections and enforcement are ongoing Based on the disturbing lack of skepticism, along with the fundamental importance of independence to the performance of quality audit work, Chairman Doty believes ‘‘it is incumbent on the PCAOB to take up the debate about firm tenure and examine it, with rigorous analysis and the weight of evidence in support and against.’’ Chairman Doty states that he does not have ‘‘a predetermined idea as to whether the PCAOB ultimately should adopt term limits My only predilection is that the PCAOB deepen the analysis of how we can better insulate auditors from client pressure and shift their mindset to protecting the investing public’’ (PCAOB 2011c)
It is important to note that the number of audit deficiencies identified in the inspection process has declined markedly over time (PCAOB 2008) Moreover, extant evidence indicates that a relatively small proportion of audit deficiencies results in a misstatement (Hermanson et al 2007; Church and Shefchik 2012)
MOVING FORWARD
Chairman Doty acknowledges the considerable implementation challenges associated with mandatory rotation Therefore, the concept release also pursues the study and consideration of ways to mitigate such challenges Chairman Doty states that the reason to consider the concept of auditor rotation is to resolve the question to which the discussion of independence, skepticism, and objectivity always seems to return That is, will term limits reduce the pressures auditors face (PCAOB 2011b)?
Chairman Doty challenges both critics and proponents alike ‘‘to do their homework, come forward with facts, and add meaningful depth to the discussion, in order that we might reach resolution.’’ He encourages the discussion to go beyond the conventional wisdom ‘‘which often stops with the assumption that term limits would mean little or no improvements in audits and higher fees.’’ While recognizing a learning curve for new auditors when auditors change, the learning curve and cost-based issues are not ‘‘uncharted waters.’’ Chairman Doty cites recent research by Glass Lewis & Co which finds that ‘‘between 2003 and 2006, more than 6,500 public companies, or nearly 52 percent of all public companies, voluntarily changed their auditors’’ (PCAOB 2011b) Chairman Doty encourages analysis and consideration of how the auditors, companies, and audit committees involved managed these voluntary changes to ensure that the new auditors were in a position to provide reasonable assurance in the early years of an engagement

In Chairman Doty’s speeches and in the text of the concept release, audit failure is used to describe what we are calling audit deficiencies It is important to note that the concept release defines audit failure as the following: ‘‘In this context, an audit failure is a failure to obtain reasonable assurance about whether the financial statements are free of material misstatement That does not mean that the financial statements are, in fact, materially misstated Rather, it means that the inspection staff has determined that, because of an identified error or omission, the firm failed to fulfill its fundamental responsibility in the audit—to obtain reasonable assurance about whether the financial statements are free of material misstatement In other words, investors were relying
on an opinion on the financial statements that, when issued, was not supported by sufficient appropriate evidence.’’ Often, audit firms do not agree with a significant number of the deficiencies found by the PCAOB.
Trang 5We note that, while a large number of auditor changes are documented for the period 2003–2006, the extent to which many of these changes was voluntary is unclear DeFond and Lennox (2011) find that, over this time period, nearly one-third of small firms with audit clients stopped performing audits altogether Such unexpected changes in auditors are not necessarily beneficial to audit quality.Blouin et al (2007)look at what happened to former Arthur Andersen clients, who were forced to change auditors, and do not find any evidence to support improved audit quality, regardless of whether clients followed Andersen personnel to a new auditor
FINAL THOUGHTS
Finally, Chairman Doty foresees an active and important role for the PCAOB in supporting a full and informed debate about how to counteract the conflicts that auditors face Therefore, he expects that the PCAOB will issue several policy documents in the near-term We applaud the PCAOB’s efforts ‘‘to foster broad debate and research about ways to enhance both the relevance and credibility of audits and to provide the investing public a better understanding of what an audit
is through enhanced transparency’’ (PCAOB 2011c) In closing, while the vast majority of academic findings are not supportive of mandatory audit firm rotation (e.g.,Cameran et al 2005; Stefaniak et al 2009), we do encourage others to participate in this important discussion of auditor independence and to not sit on the sidelines
