Is Self-Regulated Peer Review Effective
at Signaling Audit Quality?
ABSTRACT: This study examines whether peer reviews conducted under the AICPA’s
self-regulatory model have been effective at signaling audit quality Prior research has
examined whether peer-review reports are associated with perceived audit quality We examine whether peer-review reports are associated with actual audit quality Using a
unique data set obtained from the files of an insurance company, we find that review findings are indeed useful in predicting audit failure (i.e., malpractice claims alleging auditor negligence), and that certain types of findings are particularly useful in this regard We also find that peer-review findings are associated with other firm- specific indicators of potentially weak quality control or risky practices within account- ing firms Taken together, we interpret our findings to indicate that self-regulated peer review as mandated by the AICPA does provide effective signals regarding audit-firm quality.

I INTRODUCTION
This study examines the effectiveness of the AICPA’s self-regulated peer-review
proc-ess We specifically examine whether traditional peer-review reports are informativeregarding the audit quality of accounting firms Peer review has for many years been
an integral part of the AICPA’s program for enhancing quality in the auditing profession

Trang 2Originally adopted in the 1970s, the intent of peer review was to improve audit quality
primarily by identifying significant audit-firm weaknesses, and by communicating those
weaknesses to the reviewed firms so they could take corrective action (White et al 1988;AICPA 2004) It was clearly intended to be a forward-looking, rather than a punitive proc-ess.1 However, the AICPA has recently recognized that regulators and the general publicmight also use peer-review reports for decision-making purposes (AICPA Peer ReviewBoard 2004) This has led to a renewed emphasis on peer-review transparency, and to muchdebate regarding the information content of peer-review reports, including the disclosure
of audit-firm weaknesses to the public (e.g., Bunting 2004; Snyder 2004) Implicit in thisdebate are the assumptions that many parties value audit-firm quality, and that peer-reviewreports provide information regarding such quality Little is currently known about thevalidity of these assumptions
In this study, we focus on the information content of the peer-review report itself Inorder for peer review to impact audit quality, it must effectively identify weaknesses
in lower-quality firms and communicate this information in the report Without this, rective action cannot be taken, and related market pressure cannot be brought to bear.Recent actions by regulators imply that self-regulated peer review has not been an effectivemechanism in this regard For example, the Sarbanes-Oxley Act of 2002 now requires auditfirms with public clients to have PCAOB inspections regardless of their peer-review results(U.S House of Representatives 2002) This change was clearly a reaction to the observationthat most audit failures involved firms receiving clean (unmodified) peer-review reports
cor-At that time, few empirical studies existed to shed light on the issue In fact, little research
to date has examined whether peer-review reports credibly capture audit-firm quality.2This
is unfortunate since most audit firms continue to rely on self-regulated peer review to guidetheir quality-control efforts (Hilary and Lennox 2005).3 Moreover, understanding peer-review effectiveness is imperative to the ongoing debate about the extent to which theauditing profession should be self-regulated
Using a unique and proprietary data set obtained from the application files of an surance company that provides liability coverage to accounting firms, we examine the linkbetween peer-review reports and audit-firm quality We first examine whether the detailedinformation communicated in the peer-review report—specifically the associated letter ofcomments (LOC)—is helpful in predicting audit failure Using malpractice claims as evi-dence of audit failure, we find that the number of weaknesses identified in peer-reviewreports is associated with audit failure We also find that some types of weaknesses iden-tified in peer-review reports are helpful in predicting audit failure while others are not Wealso examine whether the information contained in peer-review reports is calibrated withother potential firm-specific indicators of risk Using information gathered by the insurance
in-1 The output from an AICPA peer review includes, (1) an overall report, which generally contains little or no specific information about quality-control weaknesses identified during the review, and (2) a letter of comments, which describes the specific quality-control weaknesses identified during the review, and which requires a written response Until recently, these were not generally available to the public.
2 Recent studies find PCAOB inspections to be associated with improved audit quality (e.g., Gunny and Zhang 2006; Hermanson et al 2007; Lennox and Pittman 2007), but say little about the effectiveness of traditional AICPA peer reviews This paper should help provide a basis for benchmarking current efforts at regulation against the strictly self-regulatory regime that existed prior to Sarbanes-Oxley.
3 Peer review remains a requirement for AICPA membership—even for firms receiving PCAOB inspections Because PCAOB inspections focus only on the audits of public clients, the AICPA allows members of its Center for Audit Quality (which replaced the SECPS in 2003) to have peer reviews that focus only on the other aspects
of a firm’s practice Most states continue to require peer review for CPA licensure Audit firms in many countries also have peer-review requirements similar to those maintained by the AICPA.

company specifically to aid in the assessment of audit-firm risk, we find that the number
of weaknesses identified in peer-review reports is associated with such firm-specific butes We interpret our results to be generally supportive of self-regulated peer review being

II PEER REVIEW AND AUDIT QUALITY
The AICPA has for many years incorporated peer review as one of its primary methods
of controlling quality among CPA firms Even before mandatory peer review was adopted,the AICPA had a system of voluntary peer review that started in the 1970s This wasimplemented primarily as part of the profession’s response to a wave of audit failures thatcaused the public to question audit effectiveness The voluntary phase of peer review even-tually gave way to a form of mandatory, yet self-regulated, peer review that was instituted
by the AICPA’s membership in the late 1980s at the prodding of the SEC (Berton 1987;White et al 1988) Self-regulated peer review has remained basically intact from that time
until the present—even after the creation of the PCAOB in 2002 Although the creation of
the PCAOB implied that self-regulation had failed in terms of monitoring, the AICPArecently reasserted its commitment to peer review for its membership (AICPA 2004), albeit
in a more transparent form
The effectiveness of the AICPA’s peer-review program has often been questioned Whilesome commentators have been supportive of the program (e.g., Mautz 1984; Kaiser 1989;Felix and Prawitt 1993), critics have made reasonable arguments over the years as to whyself-regulated peer review may not work Some point to the anecdotal evidence that peerreviews identify relatively few weaknesses in reviewed firms (e.g., Wallace and Cravens1994), that almost all peer-review engagements result in unmodified reports (e.g., Hilaryand Lennox 2005), and that most audit failures involve peer-reviewed firms (e.g., Fogarty1996) Others argue that peer review cannot be effective because of the general lack ofindependence among reviewers and reviewees (Anantharaman 2007; Grumet 2005), andbecause the formality of the process allows firms to develop explicit compliance plans based
on charts and checklists that have little impact on the conduct of audits (Atherton 1989;Austin and Lanston 1981) Fogarty (1996) argues that the AICPA’s peer-review programmay be nothing more than ‘‘ceremonial logic’’ because (1) the program was created by atrade organization focused more on maintaining the profession’s image than on improvingaudit quality, and (2) reviews focus on the quality-control process and documentation ofthat process rather than on the appropriateness of audit decisions and actual audit quality.While these criticisms appear reasonable, the key to determining whether peer review
is effective is to examine whether it successfully identifies quality differences among auditfirms In other words, do peer-review reports credibly reflect audit quality? Empirical studies
have shed some light on this question, but most of this evidence is indirect For example, studies examining ex post assessments of quality find that audit firms required to undergo
peer review are associated with higher-quality audits (e.g., Deis and Giroux 1992; Giroux
et al 1995; Krishnan and Schauer 2000) On the other hand, studies using fees as a proxyfor quality are less clear on this question Francis et al (1990) find no evidence that auditorssubject to peer review are able to charge higher fees However, Giroux et al (1995) findthat such firms may indeed charge higher fees, but not on a per-hour basis Similarly, a
Trang 4survey by Schneider and Ramsay (2000) suggests that while loan officers claim to havemore confidence in clients audited by peer-reviewed firms, they are not more likely toapprove loans or offer lower interest rates for those borrowers.
Wallace (1991) is the first to examine the information contained in peer-review reportsand related LOCs She finds that 90 percent of reports filed during the 1980–86 periodwere unmodified, with an average of 3.47 weaknesses identified per engagement She alsofinds that the number of weaknesses is invariant to the type of reviewer, type of reviewee,
or year of review Wallace (1991) interprets these findings as supporting the contention thatpeer review is effective in that it is not subject to moral hazard problems surrounding thechoice of the reviewing firm Hilary and Lennox (2005) examine reports filed during 1997–
2003 and find that most reports continue to be unmodified (95 percent), and that the averagenumber of weaknesses identified (1.12 per report) appears to have decreased considerablyover time Their primary contribution is to gauge the information content of peer-reviewreports by focusing on audit-market reactions to those reports Their research design makes
two assumptions: first, that audit clients perceive peer-review reports to reflect actual audit
quality; and second, that any market reaction to peer-review reports is due to audit-clients’demand for audit quality The authors find evidence that the audit market reacts to theinformation signaled by peer-review reports Specifically, firms receiving unmodified reportswithout LOCs gain clients following the review, while firms receiving modified or adversereports lose clients Shifts in the audit market also appear to be related to the number ofweaknesses identified in the LOC
Hilary and Lennox (2005) is the most complete examination to date of the informationcontent of peer-review reports They demonstrate that peer-review reports are associated
with perceived audit quality However, whether peer review provides an effective signal of audit quality ultimately depends on whether its results are well calibrated with actual audit
quality.4Unfortunately, audit quality is usually unobservable on specific audits (O’Keefe et
al 1994) Because of this, researchers generally use proxies for audit quality in their yses Such proxies often involve events suggestive of audit failure, such as restatements(e.g., Kinney et al 2004), failure to issue going-concern reports (e.g., Lim and Tan 2008),the presence of AAERs (e.g., Hilary and Lennox 2005), and audit-related litigation (e.g.,DeFond and Francis 2005; Francis 2004; Bonner et al 1998) In this vein, we believe pooraudit quality is observable with hindsight if an engagement results in litigation or a claim
anal-of malpractice against the audit firm (Palmrose 1988) That is, ceteris paribus, firms
ex-periencing legitimate malpractice claims (i.e., audit failures) are likely to provide
lower-quality audits on average It follows that if peer-review reports accurately reflect actual
audit quality, then such firms should generally have received weaker peer-review reports
prior to the events leading to the claims This leads to our first hypothesis:
H1: The likelihood of audit failure (i.e., poor audit quality) is associated with
peer-review findings
This hypothesis reflects our belief that audit failure (as proxied for by a malpracticeclaim) is a reasonable indicator of poor audit quality However, we recognize that not allaudit failures result in observable events such as lawsuits or malpractice claims We also
4 Hilary and Lennox (2005) indicate a univariate association between peer-review findings and Accounting and
Auditing Enforcement Releases (AAERs) While AAERs are a reasonable proxy for audit quality, few firms in their study had clients subject to AAERs Additionally, reviews of those firms appear to have been conducted
after the SEC investigations had begun Given the publicity surrounding SEC investigations, reviewing firms
may have felt pressure to identify weaknesses in those cases.

recognize that the existence of audit risk allows that, statistically, some claims or lawsuitsmay be associated with high-quality auditors For this reason, we also turn to insurancecompany expertise to identify other firm-specific attributes indicative of audit-firm risk and/
or lower average audit quality
During the application process, companies providing professional malpractice insurance
to audit firms collect and carefully examine firm-specific information they consider useful
in assessing the likelihood of claims or lawsuits being filed against potential clients Whilesuch information about audit-firm attributes may also reflect risks not strictly associatedwith audit quality (e.g., clientele industry or jurisdiction), it is clear that audit-firm attributesindicative of lower audit quality would be associated with increased risk to the insurancecompany, and are likely to be captured in the client-screening process It follows that ifpeer-review reports are informative about audit-firm quality, then they should also be as-sociated with the attributes identified by insurance companies as being indicative of audit-firm risk / lower audit quality This leads to our second hypothesis:
H2: Peer-review findings are associated with the presence of audit-firm attributes
in-dicative of audit-firm risk and / or lower audit quality
III RESEARCH DESIGN AND DATA COLLECTION
The data for this study are drawn from the proprietary files of an insurance company(the company) specializing in professional liability coverage for local and regional account-ing firms The company is a subsidiary of a large international professional services orga-nization and is not publicly owned It is subject to state regulation, reporting requirements,and inspection It has been in existence for more than 20 years and sells directly to itsclients, which range in size from small local firms to very large regional firms Its clientsinclude many of the largest accounting firms in the U.S In fact, our sample includes 14 ofthe largest 100 CPA firms (Public Accounting Report 1999).5 Access to the data was ob-tained through negotiations with the company, and provides us with at least three uniqueopportunities not available in prior research First, we are able to use malpractice claims
as a measure of audit failure Most of the claims in our study are the product of litigationagainst the audit firm While litigation is generally viewed as a reasonable proxy for auditquality (see Francis 2004), claims settled without litigation may represent additional inci-dents of audit failure that are generally not publicly observable In fact, aside from nuisanceclaims, these may represent relatively egregious incidents of audit failure, since the alle-gations are not even challenged in court Second, we are able to identify and use a consid-erable amount of firm-specific information not generally available to the public, includinginformation about firm histories, clienteles, structures, and services Because this data comesfrom the underwriting files of an insurance company, we are able to incorporate the com-pany’s expertise in our research design Finally, accounting firms applying for coveragewith this particular insurer are required to have peer reviews and must have received un-modified reports in their most recent review The company’s files contain copies of thesereports, including the LOCs and associated responses
In our primary analysis, we use the presence (absence) of an alleged audit failure as
an indicator of lower (higher) audit quality We first identify all audit-related claims volving accounting firms covered by the insurer during the period 1987–2000 Each ob-servation represents a unique claim for deficient audit services for which the company made

mal-to have been covered by the insurance company during the same period (i.e., firms werematched on application year and size) In order to be considered a non-claim firm, the firmmust have experienced no audit-related claims for the five years preceding the year of theobserved claim.7 The resulting sample includes 158 observations
An accounting firm’s underwriting application is updated once a year The applicationcontains information regarding the structure of the accounting firms, the services they pro-vide, the nature of their clienteles, the professional activities of their owners, and somedetails regarding their recent histories They contain no information about specific auditclients—including those associated with the incident leading to the malpractice claim Ourdata come from the underwriting files for the two years prior to the claim Data for thenon-claim firms are drawn from the same calendar periods Most of the data was hand-collected by a research assistant working directly under the supervision of one of theauthors The entire data set was then reviewed by a different author who had not beendirectly involved with initial data collection Discrepancies were resolved by re-examination
of the documents in the appropriate files
Descriptive data for the peer reviews in our sample are presented in Table 1 The reportsappear to be well distributed over the period 1986–1999 (see Panel A) The mean number
of weaknesses identified in the reports for the 158 firms was 1.44 (see Panel B) This falls
between Wallace (1991) and Hilary and Lennox (2005), and is consistent with a gradual
decrease in weaknesses over time since peer review was implemented The majority ofweaknesses relate to engagement performance, with 87 firms receiving such findings (al-most 1 per firm), followed by monitoring (29 firms, mean of 0.23 per firm) and personnelmanagement (17 firms, mean of 0.13 per firm) Few firms in our sample have findingsrelated to independence or client-acceptance issues.8
Table 1, Panel C presents the distribution of actual payouts on all audit-related claimsfiled with the insurance company It is noteworthy that during the sample period, 125 (59percent) of the 213 claims filed resulted in no payout, suggesting that the company doesnot simply settle claims to make them go away On the contrary, the data suggest that thecompany identifies frivolous claims and denies them The distribution of the remaining 88firms does not suggest an obvious bias toward smaller claims We are cautious, however,and eliminate the nine claims less than $5,000 from our sample Taken together, the payoutdistribution appears to support our assertion that the claims in our sample do not represent
6 We exclude claims involving small dollar amounts because they are more likely to represent frivolous claims rather than genuine audit failures We also exclude claims related to all nonaudit services The company tracks claims regardless of whether they result from litigation At least 56 of the 79 claims (71 percent) in our sample involved litigation.
7 Applications specifically request claims information only for the five years prior to the application year Matched firms were selected by insurance-company personnel who were not aware of the nature of the study.
8 The peer-review reports contained in the files represent reviews performed prior to the year the claim was filed.
Hence, it is unlikely that the reviewing firms felt pressure from these claims to identify weaknesses during their reviews (see footnote 4) In order to rule out the possibility that earlier claims may have impacted the reviews
in our study, we reviewed the applications and identified all claim firms that had audit-related claims within the five-year period prior to the claim of interest (and prior to the peer-review date) The mean number of weaknesses identified in the peer-review reports for these five firms was not unusually high (1.20 versus the 1.44 mean for all firms) Sensitivity tests performed after omitting these firms and their matched counterparts yield results that are qualitatively similar to those reported here.

mis-IV PEER REVIEW AND AUDIT FAILURE Model Development
Hypothesis 1 states that peer-review findings are useful in predicting audit failure (lowaudit quality) To test this hypothesis, we estimate regression models linking peer-reviewvariables to the presence or absence of malpractice claims alleging negligent, or low-quality,
audit work The dependent variable in the models (CLAIM) takes a value of 1 if a firm is
subject to a malpractice claim, and 0 otherwise Test variables reflect the findings described
in the respective LOCs Since peer-review findings apply to different aspects of an nization’s activities, we examine them both in total (Equation (1)) and separated into thefive quality-control categories (Equation (2)) used by the AICPA (1996):

otherwise
Equations (1) and (2) include control variables for non-quality factors likely to beassociated with the likelihood of claims being filed with the insurance company For ex-ample, while a link has been established between the size of a CPA firm and audit quality(e.g., Stice 1991), larger firms may experience more claims simply because they have moreclients To control for this possibility, we include the natural log of total fees for the firm
in the year prior to the claim incident (LNFEES) and the percentage change in total audit firm staff in the year of the claim incident (GROWTH).9We also include the percentage of
total firm fees coming from SEC clients (SEC%) to control for the likelihood that public
audit clients are more litigious than nonpublic audit clients We next include a dummy
variable indicating whether a CPA firm is located in either Arizona or Texas (JURIS) to
control for the possibility that claims are more likely in plaintiff-friendly jurisdictions (Esho
et al 2004).10Finally, to control for the possibility that CPA firms with low deductibles aremore likely to file insurance claims, we also include a variable measuring the policy de-
ductible divided by the number of firm owners (DEDUCT).

it does not qualitatively alter our results.

reasonable proxy for poor audit quality However, we suggest caution in interpreting our
lack of results for INDEP and ACCEPT as relatively few firms in our sample received such
