A report from the Institute of Internal Auditors ?nds that a majority of Fortune 500 com-
panies systematically rotate internal auditors out of the internal audit function and into
operational management (IIA, 2009a). We use semi-structured interviews with 11 chief
audit executives and 2 audit committee chairmen to develop an initial framework focusing
on how this practice affects ?nancial reporting quality. We then test these associations
with archival data and ?nd that companies that use a rotational staf?ng model for the
internal audit function have signi?cantly lower ?nancial reporting quality than companies
that do not. However, we ?nd that several compensating controls identi?ed from the inter-
views (e.g., consistency of IAF leadership or supervision, audit committee oversight, and
management oversight and direction) can reduce this adverse ?nancial reporting effect.
We conclude that companies should consider the potential costs of using a rotational staff-
ing model in the internal audit function and, if adopting this practice, should ensure the
appropriate compensating controls are in place to mitigate such costs.

Introduction
Approximately two-thirds of Fortune 500 companies
report that they systematically rotate their internal audi-
tors into management positions outside of internal audit
(IIA, 2009a), this practice potentially causes the internal
audit function (IAF) to be used or viewed as a training
ground for future managers (IIA, 2013). This practice is
somewhat perplexing given evidence from prior research
suggesting it diminishes internal auditors’ objectivity
(Messier, Reynolds, Simon, & Wood, 2011; Rose, Rose, &
Norman, 2013). We extend prior research on the effects
of systematically rotating internal auditors into opera-
tional management by conducting interviews with chief
audit executives and audit committee chairpersons to
develop an initial framework of how this practice is
thought to impact ?nancial reporting outcomes. We thenhttp://dx.doi.org/10.1016/j.aos.2015.05.004

use this initial framework to guide an archival analysis that
tests for the presence of key associations between such
rotation and ?nancial reporting quality.
The IAF is required to evaluate the risk exposure and
control effectiveness of the ?nancial reporting system
(IPPF, 2012). In addition, internal audit is expected to help
prevent and detect fraudulent ?nancial reporting (IIA,
2009b; IPPF, 2012) and otherwise constrain aggressive
?nancial reporting (KPMG, 2003; Prawitt, Sharp, & Wood,
2012; Prawitt, Smith, & Wood, 2009; Ege, 2015; Norman,
Rose, & Rose, 2010).
1
However, internal audit functions use a variety of staff-
ing models to ful?ll their responsibilities, including a range
of systematic rotational programs. Three common types of
rotational programs are: (1) hiring new internal auditors
from outside of the organization with the expectation that
they will spend a (preset) amount of time in internal audit
before being promoted into an operational management
position, (2) bringing operational personnel into internal
audit from within the company for a preset amount of time
on their path to operational management, and (3) sending
‘‘career’’ internal auditors into the organization for a brief
period of time to experience speci?c operational processes
before returning to internal audit. While this spectrum of
rotational programs exists in practice, prior academic liter-
ature has focused on the ?rst two types of programs and
examined how internal auditors’ ultimate goal of obtaining
a management position outside of internal audit likely
impacts his/her effectiveness as an internal auditor. Both
academics and practitioners refer to these types of rota-
tional programs as ‘‘management training grounds’’ (i.e.,
MTGs) because one of their main purposes is developing
future managers’ skills by working in internal audit (e.g.,
Burton, Starliper, Summers, & Wood, 2015; Ege, 2015;
IIA, 2013; Messier et al., 2011; Rose et al., 2013).
We posit that speci?c types of rotational programs have
the potential to reduce ?nancial reporting quality.
Consistent with prior research, we focus on the systematic
rotational programs that result in internal auditors later
obtaining management positions because these practices
are most prevalent and have the potential to impair ?nan-
cial reporting quality. Hereafter, we refer to these practices
as ‘‘systematic rotation.’’ This study does not focus on the
third type of rotational model, which sends career auditors
into operations to gain expertise before returning to inter-
nal audit, because that type of rotational program unlikely
poses the same risks to objectivity as the two other models.
We investigate whether using systematic rotation mod-
els in the IAF affects ?nancial reporting quality in two
stages. One, we draw from prior literature on external
auditor reliability (e.g., DeAngelo, 1981; Taylor, DeZoort,
Thomas, & Munn, 2003) and internal audit quality (e.g.,
Messier et al., 2011; Prawitt et al., 2009; Rose et al.,
2013), as well as regulatory guidance on internal auditor
independence and objectivity (IIA, 2001; IPPF, 2012) and
external auditors’ reliance on internal auditors (e.g., SAS
No. 128, No. 65; ISA 610; AS 5) to guide a set of interviews
with 11 chief audit executives (CAEs) and 2 audit commit-
tee chairmen. Each interviewee provides insights about the
use of systematic rotational programs in his/her organiza-
tion, including the potential costs and bene?ts of system-
atic rotation. By integrating the results of these
interviews with themes in existing literature and regula-
tory guidance, we develop an initial framework that we
test using archival data.
From the interviews and from prior research, we posit
that, in isolation, systematic rotation is likely to impair
?nancial reporting quality. We then advance the theory
and literature on this subject by examining whether com-
pensating controls focused on IAF oversight mitigate the
adverse effect on ?nancial reporting quality. In particular,
our initial framework includes three compensating con-
trols described by our interviewees that we can test: (1)
consistency of IAF leadership or supervision, (2) audit com-
mittee oversight, and (3) management oversight and direc-
tion. Prior research has not identi?ed these potential
compensating controls; however, our interviewees believe
these controls mitigate the potential impairment of inter-
nal auditors’ objectivity and competence that likely arises
when systematic rotational programs are used, such that
the bene?ts of the practice outweigh the risks.
2
Two, we conduct archival tests using data collected by
the IIA to examine the effects of systematic rotation on
?nancial reporting quality. This proprietary database rep-
resents one of the most complete sets of archival internal
auditing data that currently exists. The data identify com-
panies that use systematic rotation, other internal audit
characteristics that help control for internal audit exper-
tise, audit committee characteristics and activities, and
other possible determinants of ?nancial reporting quality,
such as ?rm governance mechanisms (e.g., management
and the external auditor). Our proxy for ?nancial reporting
quality is accounting risk, which we de?ne as the risk that
the audited ?nancial statements contain misleading and/or
fraudulent results (e.g., Price, Sharp, & Wood, 2011). We
address selection bias arising from unobservable differ-
ences in companies that do or do not use systematic rota-
tion with a Heckman self-selection model.
Consistent with our framework, we ?nd that use of sys-
tematic rotation is associated with higher accounting risk.
This result suggests that systematic rotation weakens the
effectiveness of internal audit’s monitoring of ?nancial
reporting within the organization. This result is also con-
sistent with the view from prior research that some rota-
tional IAFs operate primarily as a management training
ground, at the expense of the effectiveness of traditional
internal audit activities.
However, consistent with our predictions, other organi-
zations implement compensating controls that mitigate
this negative relation. Speci?cally, organizations that (1)
rotate only staff internal audit positions (e.g., not the head
1
In the most recent Comprehensive Body of Knowledge (CBOK) survey
conducted by the Institute of Internal Auditors (IIA), approximately 72% of
respondents indicate that their IAF performed audits of ?nancial risks and
71% report that they perform fraud investigations, representing the third
and fourth most commonly performed activities, respectively.
2
While not the focus of this paper, our interviewees also described
several important bene?ts of using rotational programs. We include
insights related to these bene?ts, when relevant, throughout the paper
and provide a list of bene?ts in Table 2.
38 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
of internal audit), (2) have more effective audit commit-
tees, or (3) have management who directs internal audit
to focus on ?nancial reporting (as opposed to operational
or IT audits) are able to reduce the negative ?nancial
reporting effects associated with systematic rotation of
internal auditors into management positions. Further, at
least in this data, when all three types of compensating
controls are present, the negative association between sys-
tematic rotation and ?nancial reporting quality is elimi-
nated. Thus, our results suggest that control-conscious
organizations can use compensating controls to prevent
systematic rotation from reducing ?nancial reporting
quality.
Our study contributes to the literature in several ways.
First, our interviews with CAEs and audit committee chair-
persons identify important institutional details about
using systematic rotation. Interviewees describe many
bene?ts of the practice (e.g., helps attract and retain talent,
improves organizational expertise with the IAF), which
helps explain why so many organizations use systematic
rotation despite potential negative consequences. Our
interviews also identify control practices that companies
use to reduce the risk of impaired IAF objectivity and com-
petence. These institutional details allow us to develop and
re?ne an initial framework of the effect of systematic rota-
tion on ?nancial reporting quality, and they guide our
archival analysis.
Second, we complement and extend prior research by
showing that systematic rotation of internal auditors into
management positions is associated with higher account-
ing risk. Complementing experimental evidence from prior
research suggests that systematic rotation can reduce
internal auditors’ objectivity and external auditors’ percep-
tions of internal audit objectivity (Messier et al., 2011;
Rose et al., 2013), archival associations reported herein
are consistent with our framework’s prediction, i.e., these
rotations can impair internal auditors’ objectivity to the
point of lowering ?nancial reporting quality. Further, these
associations obtain despite compensating work that may
be performed by the external auditor.
Third, in further tests of our framework, however, we
test several compensating controls described by our inter-
viewees, which moderate the negative effect of systematic
rotation on ?nancial reporting quality. These compensat-
ing controls provide various oversight mechanisms within
the company intended to improve the IAF’s willingness and
capacity to prevent and/or detect low quality ?nancial
reporting. This aspect of our study builds on Rose et al.
(2013), who examine whether giving directors power over
the appointment of senior managers in?uences the adverse
effect of systematic rotation; however, Rose et al. (2013)
do not investigate the broader issue of corporate gover-
nance strength, such as audit committee oversight and
effectiveness.
3
In addition, prior research has not examined
IAF leadership consistency or management’s direction for
the IAF as compensating controls.
Finally, we contribute to the literature and to practice
by providing evidence on the effects of using the CAE posi-
tion as a rotational position. Many of our interviewees
expressed concerns about internal audit competence and
objectivity when the head of internal audit is a rotational
position, and our archival analysis con?rms that rotating
the head of internal audit is associated with low ?nancial
reporting quality. The results of our analysis inform the
on-going debate among practitioners regarding the appro-
priateness of this practice. Overall, our results add to the
limited prior literature on how the IAF affects its organiza-
tion’s economic, operational, and ?nancial reporting
outcomes.
Evidence on the consequences of systematic rotation
will also be interesting to investors, boards of directors,
audit committees, and management. These stakeholders
rely on the IAF to monitor ?nancial reporting, and they
can bene?t from evidence about how systematic rotation
affects ?nancial reporting quality. Furthermore, regulators
and standard setters, such as the IIA, would bene?t from
understanding how these rotational assignments affect
?nancial reporting quality and what organizations can do
to address the potential consequences.
In the next section, we use the literature on internal
auditor quality to begin to develop our initial framework
and develop our hypothesis on the effect of systematic
rotation on ?nancial reporting quality. We then describe
our interview method, after which we use the insights
gained from our interviews to re?ne our initial framework
and develop hypotheses on the moderating effects of three
compensating controls. The section titled ‘Archival data
and model speci?cation’ describes our archival analysis.
We report the results of our hypotheses tests in the subse-
quent section and then conclude.
IAF quality and ?nancial reporting quality
The IAF is one of the cornerstones of effective corpo-
rate governance and ?nancial reporting (IIA, 2003;
Gramling, Maletta, Schneider, & Church, 2004, Reding
et al., 2009). By the IIA’s de?nition, internal audit should
bring a ‘‘systematic, disciplined approach to evaluate and
improve the effectiveness of risk management, control,
and governance processes’’ (IIA, 2011a). Standards for
the internal auditing profession af?rm the IAF’s responsi-
bility to monitor ?nancial reporting (e.g., IPPF, 2012) and
help detect and deter fraud (e.g., IIA, 2009b; IPPF, 2012),
as well as reduce related losses (Coram, Ferguson, &
Moroney, 2008; Ege, 2015; KPMG, 2003; Norman et al.,
2010).
Prior academic research similarly has shown that an
effective IAF improves: risk assessments (Asare,
Davidson, & Gramling, 2008; Sarens & De Beelde, 2006),
safeguarding of assets (Beasley, Carcello, Hermanson, &
Lapides, 2000; Coram et al., 2008), earnings quality
(Abbott, Daugherty, Parker, & Peters, 2013; Prawitt et al.,
2009), deterrence of management misconduct (Ege,
2015), internal control strength (Lin, Pizzini, Vargus, &
Bardhan, 2011), audit quality (Prawitt et al., 2012), and
audit ef?ciency (Felix, Gramling, & Maletta, 2001; Pizzini,

Rose et al. (2013) ?nd that empowering the board of directors to
promote internal auditors into senior management positions increases the
adverse effect of systematic rotation on objectivity.

Lin, Vargus, & Ziegenfuss, 2011; Prawitt, Sharp, & Wood,
2011).
Prior research generally considers internal auditing at
a relatively high level (e.g., an overall composite measure
of internal audit strength) and institutional details of the
internal auditing environment are sometimes overlooked
(Koonce, 2013). Thus, one purpose of this paper is to pro-
vide rich institutional details from interviews with heads
of internal audit (i.e., chief audit executives) and audit
committee chairmen who describe how internal audit is
practiced. We then use these institutional details to
develop an initial framework to guide our archival
analysis.
We begin by reviewing the existing academic research,
practitioner literature, and regulatory guidance on internal
and external auditor reliability. We extract common ele-
ments and to develop an initial framework of factors that
(should) impact the IAF’s effect on ?nancial reporting qual-
ity. In particular, we draw from: (1) The International
Standards for the Professional Practice of Internal
Auditing promulgated by the IIA, which provide the basic
requirements for internal auditing; (2) various external
audit standards that govern how external auditors are to
evaluate IAFs when using their work as part of the external
audit
4
; (3) DeAngelo’s (1981) model describing external
audit quality as a function of auditor technical ability and
independence/objectivity; and (4) Taylor et al.’s (2003)
framework describing external auditor reliability as a func-
tion of expertise, objectivity, independence, and integrity.
5
Although DeAngelo’s model and Taylor et al.’s (2003) frame-
work focus on external auditor quality and reliability,
respectively, the underlying components are relevant to
internal auditors as well.
6
Indeed, Taylor et al. (2003) state
that their framework ‘‘has the potential to clarify responsi-
bilities and guide other critical ?nancial reporting and cor-
porate governance groups, such as internal auditors’’ (264).
Our examination of these sources reveals two impor-
tant commonalities. First, objectivity is central to high
quality auditing. For example, Taylor et al. (2003) argue
that external auditor reliability ‘‘can be achieved only by
the relentless pursuit of objectivity’’ (p. 262). Similarly,
internal audit standards state that ‘‘internal auditors must
be objective in performing their work. . .Objectivity is an
unbiased mental attitude that allows internal auditors to
perform engagements in such a manner that they believe
in their work product and that no quality compromises
are made. . .Objectivity requires that internal auditors do
not subordinate their judgment on audit matters to others’’
(IPPF, 2012, pp. 3–4). Finally, for evaluating internal audi-
tors, AS 5 states ‘‘the auditor should not use the work of
[internal auditors] who have a low degree of objectivity,
regardless of their level of competence.’’
Second, the competence or expertise of internal audi-
tors also is key. Internal audit standards state that ‘‘internal
auditors must possess the knowledge, skills, and other
competencies needed to perform their individual responsi-
bilities’’ (IPPF, 2012, p. 5). ISA 610 (revised) states,
‘‘Competence of the internal audit function refers to the
attainment and maintenance of knowledge and skills of
the function as a whole at the level required to enable
assigned tasks to be performed diligently and in accor-
dance with applicable professional standards’’ (p. 13).
Other external audit standards mirror this language, and
the DeAngelo (1981) model and the auditor reliability
framework (Taylor et al., 2003) suggest expertise is a key
component of external audit quality. In sum, all of the
sources we have reviewed consider objectivity and compe-
tence to be central to high performing IAFs.
7
Importantly, systematic rotation has the potential to
impair the objectivity and competence of the internal audit
function. Although there exists a spectrum of rotational
staf?ng models used by organizations, we followprior liter-
ature and focus on rotational models that result in internal
auditors systematically leaving the IAF for management
positions (e.g., Ege, 2015; Messier et al., 2011). In one such
model, the IAF hires new auditors from outside the com-
pany, promising them a short tenure (e.g., two to three
years) in internal audit followed by the opportunity to
assume management positions within operations.
Alternatively, other organizations populate the internal
audit function with existing operational personnel who
use a short termin the IAF to become knowledgeable about
risk and control before being promoted into other opera-
tional positions.
8
While there are notable differences in
these two rotational staf?ng models, each is likely to have
similar effects on the objectivity and competence of the
internal auditors within them because the internal auditors
are motivated by the ultimate goal of obtaining future
4
We refer to SAS No. 128, Using the Work of Internal Auditors (which
supersedes SAS No. 65, The Auditor’s Consideration of the Internal Audit
Function in an Audit of Financial Statements); ISA 610 (revised 2013), Using
the Work of Internal Auditors; and AS 5, An Audit of Internal Control Over
Financial Reporting that is Integrated with an Audit of Financial Statements. A
signi?cant body of research supports that external auditors follow these
standards when evaluating IAFs (e.g., see Bame-Aldred, Brandon, Messier,
Rittenberg, & Stafaniak, 2013; Glover, Prawitt, & Wood, 2008; Gramling
et al., 2004).
5
Taylor et al. (2003) develop the external auditor reliability framework
which is tested by DeZoort, Holt, and Taylor (2012).
6
Prior research often uses the terms reliability and quality interchange-
ably (e.g., Taylor et al., 2003). Similarly, the terms competence/expertise
and objectivity/independence are also often used interchangeably in the
literature. Differentiating between each of these concepts is beyond the
scope of this paper. Therefore, when discussing prior literature we use the
term(s) used in each speci?c paper and as a result, also use the terms
somewhat interchangeably.
7
Each source also describes other attributes of a high quality IAF. For
example, the internal audit standards suggest the importance of quality
assurance programs and speci?c performance standards (e.g., guidelines of
how to plan, perform the engagement, and communicate ?ndings). External
auditing standards state that the internal auditors’ work must relate to the
external audit, and the external auditor reliability framework focuses on
other factors that increase objectivity, such as integrity and independence.
We retain the simple two-factor model of objectivity and competence to
guide our interviews because objectivity and competence are common
across all sources we reviewed and because other factors often lead to
objectivity and competence (e.g., see discussion in Taylor et al., 2003).
8
Home Depot has publicized its use of systematic rotation to hire new
auditors into the organization from the outside, with the express intent to
go into a business manager role after two years. GE is one of the most
prominent companies to employ systematic rotation to staff the internal
audit department with current operational personnel who intend to
advance to higher positions after a stint in internal audit (Baker, 2010).
Organizations also vary in the extent to which rotating into or out of
internal audit within a certain timeframe is optional (Baker, 2010).
40 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
positions outside of the IAF.
9
We consider these two rota-
tional staf?ng models together, which is consistent with
prior literature (e.g., Ege, 2015; Messier et al., 2011; Rose
et al., 2013).
Fig. 1 illustrates the theoretical relationships modeled
in our initial framework of the effect of systematic rotation
of internal auditors on ?nancial reporting quality.
Objectivity
Systematic rotation could impair internal auditors’
objectivity by creating a dependent relationship between
the internal auditors and members of management who
are considering them for promotion (Chadwick, 1995;
Hoos, Messier, Smith, & Tandy, 2014; Wood & Wilson,
1989). As noted in Stewart and Subramaniam (2010), sys-
tematic rotation can induce social pressures and economic
interest threats to the independence and objectivity of the
IAF. In particular, there is the potential for systematic rota-
tion to focus internal auditors on obtaining or performing
future positions outside of the internal audit department,
diminishing their objective assurance over ?nancial report-
ing processes.
10
This potential is consistent with the general conclusion
of prior studies on systematic rotation. Using experiments,
Hoos et al. (2014) and Rose et al. (2013) provide evidence
that internal auditors are less objective given systematic
rotation.
11
Relatedly, Messier et al. (2011) ?nd that external
auditors perceive rotational internal auditors to be less
objective, and that audit fees are higher for companies that
rotate internal auditors into operations. The latter effect is
interpreted as evidence that the external auditors do more
work to compensate for the (perceived) impaired objectivity
of rotational auditors. Taken together, prior literature sug-
gests systematic rotation causes impaired objectivity.
Competence
Systematic rotation could compromise the internal audit
competence of the IAF for several reasons. One, employees
who view internal audit positions as a stepping stone to
management opportunities are less likely than others to
pursue training and certi?cations that would improve their
internal audit competence (Anderson, 2010). Two, the con-
stant rotation out of the IAF diminishes overall IA experi-
ence and expertise relative to models with ‘‘career’’
auditors (Anderson, Christ, Johnstone, & Rittenberg, 2010).
Research examining whether rotational staf?ng models
affect internal auditors’ competence is less prevalent than
examinations of its effects on independence and objectiv-
ity and yields somewhat mixed results. The same Messier
et al. (2011) paper discussed earlier reports no difference
in how external auditors perceive the competence of
non-rotational versus rotational internal auditors.
However, Ege (2015) uses archival data from the IIA and
?nds that measures of internal auditor competence (e.g.,
internal audit certi?cations and experience) are negatively
correlated with systematic rotation. Thus, it is reasonable
to conclude that the internal audit competence of a rota-
tional IAF will be similar or lower (but not higher) than
that of an IAF that does not use systematic rotation.
Taken together, previous literature suggests that using
systematic rotation is likely to be associated with lower
objectivity, and possibly lower competence among internal
auditors. Therefore, when considering the overall relation-
ship between systematic rotation and ?nancial reporting
quality, we predict that it will be associated with weaker
?nancial reporting quality than non-rotational internal
audit departments.
12
Stated formally:
H1. Systematic rotation lowers ?nancial reporting quality.
We next describe our interview process that led us to
further develop our framework.
Interview method
We interviewed heads of internal audit (i.e., CAEs) from
11 companies of varying sizes and industries and two audit
committee chairpersons who (combined) have worked
with 12 unique companies.
13
Table 1 provides demographic
information for our interviewees. Our heads of internal audit
vary in direct experiences with systematic rotation. Eight of
eleven companies use formal rotation programs, one uses
informal rotation, and two do not use rotation. However,
all of our interviewees indicated they had considered and
discussed this practice within their organizations.
Similarly, both audit committee chairmen sat on boards of
companies that did and did not use rotational models, and
both were knowledgeable about the practice.
Our goal in obtaining this varied sample was to learn
both positive and negative perspectives about systematic
rotation, especially aspects of the practice that may in?u-
ence the objectivity and competence of the IAF and, as a
result, ?nancial reporting quality. We developed a
semi-structured interview protocol (see Appendix A) with
open-ended questions (Lillis & Mundy, 2005; Yin,
2009).
14
Interviews began with questions about the
9
One notable difference between these models is that rotational models
that hire new auditors from outside the company are less likely to gain
organizational knowledge and expertise, which is a potential bene?t when
existing operational employees rotate through the IAF. This bene?t is
discussed more thoroughly in a later subsection.
10
For additional discussion of how rotational internal auditors may be
consciously or unconsciously biased, see Rose et al. (2013) and Koonce
(2013).
11
Hoos et al. (2014) show that rotational internal auditors are more likely
than non-rotational internal auditors to make recommendations that
management would prefer. Similarly, Rose et al. (2013) ?nd that rotational
auditors are more likely than non-rotational auditors to agree with
management’s aggressive accounting policies.
12
There is an additional reason we may not observe the relation
hypothesized in H1. The results of Messier et al. (2011) suggest that
external auditors are concerned about the potential lack of objectivity in
rotational IAFs; therefore, they price external audit services higher for these
?rms. If external auditors do more work to compensate for the lower
objectivity of the IAF, rotation will have no effect on ?nancial reporting
quality.
13
The audit committee chairmen served on the boards for multiple
companies, so we do not include them in cited statistics but rather discuss
their responses in general when they provide pertinent additional details.
14
Semi-structured questions allow for consistency, and thus higher
internal validity, while not restricting our ability to uncover new ideas
and concepts.

background of the organization, the head of internal audit
(or audit committee member), and the IAF. Interviews pro-
gressed to discuss speci?c experiences with systematic rota-
tion as well as the bene?ts and drawbacks of this practice for
internal auditors’ objectivity and competence. We concluded
the interviews by asking for descriptions of practices (i.e.,
compensating controls) used to ensure that the systematic
rotation was successful. Interviews lasted an average of
46 min. In Table 2 we report the risks, bene?ts, and compen-
sating control identi?ed by CAE interviewees and the num-
ber of individuals who speci?cally mentioned each.
To identify interviewees, we contacted the IIA who
reached out to potential interviewees on our behalf. Six
of eleven (55%) interviewees are from Fortune 500 compa-
nies. Internal audit department size ranges from 3 to 97
employees, and interviewees’ experience in their current
position ranges from 1 to 25 years. We identi?ed audit
committee member interviewees through accounting pro-
fessors from two universities. The audit committee mem-
bers represent 12 unique companies (9 public and 3
private), all with revenues over $1 billion in 2013.
One author conducted telephone interviews with all
heads of internal audit. Two authors conducted audit com-
mittee chairmen interviews in person. In general, we asked
questions in the order shown in the interview protocol;
however, we allowed interviewees to elaborate and move
to relevant or related topics naturally. We asked clarifying
questions as needed.
All interviews were recorded and transcribed, and later
coded independently by one author and one research
Fig. 1. Initial framework of the effects of systematic rotation on ?nancial reporting quality. This ?gure displays the initial framework we develop based on
prior literature and our interviews. The relationships that we test in this paper are shown with a solid line. Because we use archival analysis using data from
the IIA GAIN database, we do not directly test (or hypothesize) the effect of systematic rotation on internal auditor objectivity or independence. However,
we recognize that these are the underlying mechanisms through which systematically rotating internal auditors into management positions in?uences
?nancial reporting quality (shown with dashed lines). We also show several other compensating controls, described by interviewees, which we cannot test
with existing data, but should be explored in future research.

assistant. To code the interviews, one author reviewed
each transcript and identi?ed speci?c passages in which
an interviewee mentioned a risk or bene?t of systematic
rotation or a compensating control. The author then cate-
gorized each passage as a risk, bene?t, or control. The
research assistant then independently reviewed the inter-
views, identi?ed passages, and assigned each to one of
the same categories (i.e., risk, bene?t, or control). Any pas-
sages that the second coder could not categorize within the
initial set of choices were temporarily coded as other. The
coders identi?ed 133 passages related to risk (35), bene?ts
(54), and compensating controls (44). Inter-rater agree-
ment after the ?rst pass was 94%. The coders examined
and discussed any discrepancies until agreement was
reached.
Re?ning our initial framework for the effects of
systematic rotation on ?nancial reporting quality
In this section, we report insights fromour interviews. In
general, the interviewees’ comments support our predic-
tion in H1 that systematic rotation tends to cause lower
?nancial reporting quality, at least in absence of compen-
sating controls. In particular, our interviewees discussed
how systematic rotation lowers internal auditor objectivity
and competence—and is therefore likely to impair the orga-
nization’s ?nancial reporting quality (if left unchecked).
Additionally, interviewees indicate it is important to
expand our framework to consider compensating controls
that are likely to moderate these negative relationships.
Consistent with Taylor et al.’s (2003) conjecture that other
types of quality controls (e.g., training, reviews) may com-
pensate for a lack of external auditor independence, our
interviewees suggest that the following control mecha-
nisms can mitigate the adverse effects of systematic rota-
tion: (1) consistent and continuous IA supervision, (2)
audit committee’s oversight of the IAF, and (3) manage-
ment’s oversight of and direction for the IAF. Our intervie-
wees described these factors as a key compensating
control that mitigates the risk of diminished objectivity
and/or competence in internal auditors due to systematic
rotation. We extend prior literature by including these
controls in our initial framework (see Fig. 1).
Objectivity and competence
Many of the internal auditors we interviewed agreed to
some extent that systematic rotation can impair objectiv-
ity, competence or both. Eight of the eleven (73%) CAEs
acknowledged that internal auditor objectivity could be
impaired by systematic rotation. For example, CAE9
remarked,
‘‘That is a clear risk if they come in with the wrong mind
set [that] I’m just going to make friends and not call
things out in order to get a job in another area. . .’’
Similarly, CAE5 explained,
‘‘For instance, you do an audit in an area, and somebody
pulls a punch on a ?nding and doesn’t report the ?nding
because ‘gee, you know, I talked to so and so, and
they’re going to offer me this job when I get done with
this audit....’ So you have that risk.’’
Furthermore, CAE3 stated,
‘‘There is always [an objectivity] risk. If you’ve kind of
got your eye on sort of a sweet job out there that you’d
like to get, it comes into question of how likely is it that
you’re going to really raise a serious audit ?nding if you
know it’s going to be. . .a hard sell. I think that is a risk’’
With respect to competence, 8 of 11 (73%) interviewees
acknowledged that when internal auditors rotate out of the
IAF and into the organization, there is the potential for a
loss of internal audit expertise. For example, CAE10
described concerns about IAFs that rotate all internal audit
positions (i.e., no core group of ‘‘career’’ auditors is
retained):
‘‘I would argue if . . .[we’re] turning over my entire
internal audit group every two years. . .If I’m a board
member, an audit committee member, I would look
back and say, ‘How can you be giving me quality assess-
ments and quality audit work if everybody in your staff

or less?’’’
Similarly CAE7 said:
‘‘If you had an audit team that was full of . . . rotational
type people, you probably wouldn’t build up that sort of
expertise and knowledge. . . I could see a risk of a pure
rotational type function. You would just lose a lot of
corporate knowledge, and [that is a] key thing I would
think about.’’
However, several CAEs (6 out of 11) also described an
increase in organizational expertise gained from systematic
rotation—a potential bene?t not considered in prior aca-
demic research. Organizational expertise relates to knowl-
edge about the speci?c operations and procedures that
compose the core processes of the business. For example,
if an individual from manufacturing spends a two-year
rotation in internal audit as a stepping stone to a manage-
ment position, (s)he will bring speci?c knowledge about
manufacturing processes, risks, and controls into the inter-
nal audit function that may be dif?cult to gain simply by
auditing that process. In fact, many of our interviewees
believed the gain in organizational expertise could out-
weigh the loss of audit expertise. For example, CAE4 said,
‘‘Whenyoutalkabout competency, if you’re talking about
competency of the department, if we didn’t have rota-
tional [auditors], there would be more people involved
in internal auditing, and probably more sophisticated
internal auditing; but as far as expertise, havingrotational
[auditors] enlightens people and provides more wisdom
to them from the competencies that they’re bringing in,
so it enhances the department totally.’’
Also related to competence, Burton et al. (2015) ?nd
that more accounting students are willing to apply for an
internal auditing position if it will include systematic rota-
tion. This suggests that rotational IAFs will have a deeper
pool of candidates fromwhich to hire better quality profes-
sionals. Many of our interviewees echoed this sentiment.
In particular, 6 of the 11 (55%) CAE interviewees speci?-
cally mentioned that systematic rotation helps them
recruit and retain quality internal auditors. For example,
as CAE6 described,
‘‘It’s a great way to hire great people, and high-potential
people. . .If you’re just hiring internal auditors who are
quali?ed for the position to be internal auditors, you
probably aren’t going to get many of the best. So it puts
you in the market.’’

44 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Similarly, CAE5 explained,
‘‘[The] rotational program is good from the depart-
ment standpoint, because you’re going to have highly
motivated people. You’re going to have people who
seek career opportunities. You’re going to have people
who really are going to go in there and want to do
their best job because that’s how they’re going to
get the, you know, attention of people in the company
to want to hire them into their organizations,
their departments. So you don’t have to motivate
people.’’
Both audit committee chairmen echoed the belief that
using a systematic rotational staf?ng model attracts more
and better people.
In summary, although prior academic research pro-
vides relatively little evidence about the effect on compe-
tence of systematic rotation, our interviews suggest this
can have both positive and negative effects on IAF compe-
tence. Interviewees suggest that systematic rotation could
increase internal auditors’ competence by attracting more
and better people, and the IAF can bene?t from the oper-
ational expertise of operational personnel rotating
through the department. On the other hand, a high rate
of turnover within the internal audit department can also
lead to a loss of technical audit skills and audit expertise.
On balance, however, the loss of internal audit compe-
tence has the potential to hamper ?nancial reporting
quality. Thus, taken together, our interviewees provided
insights suggesting that systematic rotation poses risks
of impaired objectivity and competence consistent with
our prediction in H1.
Compensating controls
Our interviews revealed several critical compensating
controls companies can use to mitigate the impairment
of objectivity and (possibly) competence associated with
systematic rotation. The compensating controls described
by the interviewees provide various forms of oversight
over the IAF which can improve the IAF’s willingness
and capacity to prevent and/or detect low quality ?nan-
cial reporting. We conclude that the CAEs believe these
controls reduce the risk of impaired objectivity and com-
petence suf?ciently that the bene?ts of using the sys-
tematic rotational models exceed the risks. This is
consistent with Goodwin and Yeo’s (2001) ?nding that
nearly half of surveyed internal auditors disagreed that
the systematic rotation of internal auditors could impair
their work.
Although Taylor et al. (2003) conjecture that there may
be compensating controls that moderate the relationships
explored in their external auditor reliability model, with
the exception of a few studies that consider the effects of
audit committee activities, prior research has not
addressed the important compensating controls our inter-
viewees identi?ed. Based on our interviews, we include the
following compensating controls in our initial framework
as potential moderating variables and test their effects
with our archival data: (1) consistency and continuity of
IA supervision, (2) audit committee oversight, and (3)
management oversight and direction.
15
Consistency of IA supervision
Seven of the eleven (64%) CAEs and both audit commit-
tee chairmen described the importance of maintaining
some consistency in the higher levels of the IAF to reduce
the risk of diminished independence or competence result-
ing from systematic rotation. Most felt it was important to
have some career positions within the IAF (i.e., auditors
who did not rotate). For example, CAE3’s organization only
rotates internal auditors below the senior level:
‘‘One of the reasons that I set the program the way I did,
so that senior auditors and above no longer have to
rotate, is to try to maintain that continuity within the
department. . .there is that [competency] risk, and one
of the risks that I have right now is with such a small
department, if I do lose my senior, for example, then
that becomes a huge loss of support in that consistency
[and] de?nitely expertise.’’
Our interviewees described several ways that maintain-
ing some consistency in the department, especially at the
higher levels, helps to reduce objectivity and competence
concerns: higher level auditors reviewing others’ work
(45%), training and mentoring rotating staff and seniors
(45%), and facilitating discussions to ensure there are no
objectivity concerns (9%).
16
For example, CAE3 described
the importance of suf?cient supervision to reduce the
threats to objectivity:
‘‘[The] biggest way to mitigate that [objectivity] risk is
to really make sure that the folks that are not in line
of that succession, so a senior or above, [are] deeply
enough involved in the audit to where any
issue. . .would require collusion in order to bury it.’’
CAE9 also described the importance of mitigating con-
trols such as supervisory review, monitoring, and targeted
conversations:
‘‘It’s about conversations with the person, making sure
how they think, kind of what they’re looking at, how
they’re perceiving different risks that they’re seeing
15
Our interviewees identi?ed several other important compensating
controls that we do not currently test in this initial framework. These
include (1) prohibiting internal auditors from auditing departments for
which they have worked for at least 1 year (55%), (2) careful hiring
practices within internal audit (45%), (3) supervisory review of audit work
(45%), (4) training and mentoring of internal auditors (45%), and (5)
requiring a con?ict of interest statement (18%). We do not test these
additional compensating controls within this initial framework due to data
limitations; however, future research should consider their effects as
mitigating controls to reduce the potential risks associated with rotating
internal auditors into operational management positions.
16
These arguments are somewhat akin to the ?ndings on the effects of
external audit partner (and ?rm) rotation on audit quality, which describe
reduced audit quality after a rotation presumably due to the new auditor’s
lack of client-speci?c knowledge (e.g., Chi, Huang, Liao, & Xie, 2009).
Although regulatory bodies suggest that auditor rotation will improve audit
quality by allowing for a fresh set of eyes to review the ?nancials, this
comes at the loss of experience and knowledge which might can, at least
initially, outweigh the bene?t.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 45
out there, and then what actions they’re taking to fol-
low up on them to make sure that they’re digging all
the way down to get to the root cause.’’
With respect to the consistency and continuity of
supervision within the IAF, one of the critical decisions that
companies must make is whether to rotate the CAE posi-
tion speci?cally. Fifty-?ve percent of our interviewees
described concerns that there are increased risks to IAF
objectivity and competence when the CAE role is rotated.
Interviewees suggested that by rotating this position the
IAF not only loses valuable supervisory skills and internal
audit expertise, but the position is often ?lled by someone
with less (or no) internal audit experience. CAE3 described
the trend of rotating the CAE position as follows,
‘‘For me, it’s kind of a disturbing trend. I ?nd it problem-
atic, and I know why [management is] doing it. [They
want to] increase that ‘audit knows the business’ ele-
ment. . .but I don’t think they realize exactly how much
of a hole that person is in, starting from zero to try and
lead an audit function. There’s such a learning curve,
and it’s not something that they’re going to pick up in
six months or a year. . . I think it’s a big disconnect on
the part of management as far as understanding how
internal audit works.’’
With respect to objectivity, some interviewees
expressed concerns that the CAE would focus primarily
on pleasing executive management. CAE5 described the
risk as follows:
‘‘You know, the mindset of a career professional chief
audit executive, in my opinion, is different than the
mindset of a rotational chief audit executive. My job
[as CAE is] to make sure I did a dog-gone good job as
the chief auditor and make sure that the audit commit-
tee’s rear end was protected. Rotational chief auditors
may not have that as their goal and may have the goal
of, I want to become the CFO someday or the CEO, so I
want to keep the people and executive management
happy, and just sort of hope to keep the audit commit-
tee happy.’’
CAE5 continued to explain how a rotating CAE may face
challenges when reporting identi?ed weaknesses to execu-
tive management,
‘‘As a career auditor, I just know the challenges that a
person has when you’ve got to walk in and tell the
CFO or the CEO that something is going wrong in your
area and [they’re] not necessarily happy to hear it.
And so to me, it’s a lot easier when it’s like this is my
job, that’s the way I’m calling it, and I’ve got to tell
you this versus, gee, if I just sort of like kind of tell
you, and I don’t really tell the audit committee or any-
body else, and you’re still happy, we can go ?x the prob-
lem, and good, and everybody is going to be happy with
this, and that problem just goes away and gets ?xed. . .A
career auditor will know that I have a ?duciary respon-
sibility to let people know this thing is a problem, needs
to be addressed, and yeah, it’s probably going to get
?xed, but I’m going to tell the audit committee, because
they need to be aware of it.’’
CAE3 described a related but different risk to objectivity
when the CAE is a rotating position. In particular, he
described how it can affect the objectivity of the current
IAF staff because they could be uncomfortable auditing a
former supervisor:
‘‘When the chief audit executive is rotating as well, I
think that’s where you start to really run into some
impairments, because then you’ve got a really close
tie with. . .that individual who is now out in the busi-
ness. And so you take an audit staff, and they actually
end up in a position of auditing their former boss.’’
Finally, AC2 summarized these concerns when he
explained why none of the companies with which he was
involved rotated the CAE position:
‘‘[We] just felt that it was better to have stability at the
top, because we did feel that we wanted to have, if we
could, more rotation underneath. And having stability
at the top was a way of providing more continuity and
just felt that if the whole thing was turning over, that
was going to be just a little more dif?cult to manage.’’
In sum, we expect that maintaining consistency and
stability in the IAF can mitigate the risk of impaired IAF
objectivity and competence when internal auditors are
systematically rotated into management positions.
Formally, we hypothesize:
H2. Among companies using systematic rotation, limiting
it to internal audit staff only (not CAE) increases ?nancial
reporting quality.
Audit committee oversight
Audit committees are responsible for ?nancial report-
ing quality and for overseeing internal and external audit
processes; however, due to a variety of factors (e.g., organi-
zational complexity, internal auditor reporting lines), audit
committee effectiveness can vary widely in this regard
(Beasley, Carcello, Hermanson, & Neal, 2009). IIA
Standards require that the CAE report to the audit commit-
tee (or an equivalent) and recommends a dual reporting
relationship in which the CAE reports functionally to the
audit committee and administratively to senior manage-
ment (Alkafaji, Hussain, Khallaf, & Majdalawieh, 2010).
Prior literature shows that the audit committee is often
involved with hiring and ?ring the CAE and reviewing or
approving the internal audit budget. Further, in many
organizations the audit committee meets frequently and
privately with the CAE (Anderson, Christ, Johnstone, &
Rittenberg, 2011; Beasley et al., 2009). Beasley et al.
(2009) interview 42 audit committee members and pro-
vide rich descriptions of audit committee activities, includ-
ing internal audit oversight. Drawing from agency theory
(e.g., Jensing & Meckling, 1976) and institutional theory
(e.g., Cohen, Krishamoorthy, & Wright, 2007; Scott, 1987)
the authors consider whether audit committees’ practices
are more indicative of effective monitoring of manage-
ment, as predicted by agency theory or primarily serve cer-
emonial purposes, as predicted by institutional theory.
46 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Results of the interviews are mixed, suggesting that
although some audit committee members are committed
to effective monitoring, ceremonial activities commonly
occur in some organizations. To the extent that an audit
committee’s activities are primarily ceremonial, they will
not translate into an effective audit committee. Much like
audit committee performance, the internal audit function
likely varies widely (Beasley et al., 2009).
Prior accounting research suggests that audit commit-
tee oversight is an important factor that moderates the
proposed negative relation between the use of systematic
rotation and ?nancial reporting quality (Abbott, Parker, &
Peters, 2007, 2010; Agoglia, Doupnik, & Tsakumis, 2011;
Goodwin & Yeo, 2001). For example, Goodwin and Yeo
(2001) ?nd some evidence that systematic rotation is clus-
tered in ?rms with strong audit committees, which they
speculate, but do not test, could mitigate potential objec-
tivity concerns. Abbott et al. (2007, 2010) suggest that high
quality audit committees may be able to provide suf?cient
oversight when internal auditor independence is threat-
ened.
17
Rose et al. (2013) ?nd some evidence that audit
committees with more power over management’s promo-
tion opportunities are associated with less objective (rotat-
ing) internal auditors.
18
Overall, prior research suggests
that an effective audit committee may be able to reduce
the negative effect on ?nancial reporting quality associated
with systematic rotation that we hypothesize in H1.
Interviewees agree with the prior research. In particu-
lar, 6 out of 11 interviewees (55%) discussed the impor-
tance of audit committee oversight and direction. For
example, CAE1, CAE5, and CAE11 (respectively) describe
the monitoring role of the audit committee over the IAF:
‘‘We do an annual risk assessment. The audit committee
is part of that risk assessment. They approve my audit
plan. Every year they approve any changes I make to
the audit plan. To the extent there are hot topics,
emerging issues, things that are on their mind, they’re
certainly going to bring those up, and we’ll incorporate
them as appropriate.’’
‘‘Well, we certainly spent time with our audit commit-
tee to talk to them about, for instance, when we devel-
oped our audit plan and presented our audit plan. We
went through with them the approach we went and
identi?ed for our risk assessment, so that they would
understand why there were certain audits that were
in the plan.’’
‘‘The audit committee is heavily involved, quite frankly,
so they see I work for them indirectly, right? They
appoint me. They could get rid of me, they do my bud-
get approval each year, my rating, my top, everything
associated with the program, they’re involved with.’’
CAE2 also describes how his/her audit committee is
aware of IA staff rotations:
‘‘I meet quarterlywith[the audit committee] andwe pro-
vide to them on that quarterly basis an update of where
we are on the plan, how many hours, for example, etc. I
provide them updates real time on staff changes, so if I
have someone leaving or moving into the organization,
they know about it within a quarter, generally sooner.’’
Relatedly, CAE4 indicated that his/her audit committee
monitors the success of the rotational program based on a
pre-established metric (e.g., rotate two internal auditors
into the business per year) in the same manner that they
evaluate the IAFs performance relative to other metrics.
Audit committees can improve ?nancial reporting qual-
ity in a variety of ways such as asking external auditors to
do more work, questioning management to a greater
degree (Gendron & Bedard, 2006), shifting internal audi-
tors’ work to focus on ?nancial audits, increasing informal
meetings and communication with the IAF (Zaman &
Sarens, 2013), or other similar activities. Our interview
with AC1 supported this notion:
‘‘[The] compensating control is that as an audit commit-
tee member and as the [audit committee] director, we
get all the audit reports. We not only get their summary,
but we get the entire report that’s written up, so after a
while, you get so you can sort of judge quality.’’
The interviews and prior research lead to our third
hypothesis.
H3. Among companies using systematic rotation, those
having relatively strong audit committee oversight have
higher ?nancial reporting quality.
Management oversight and direction
Prior literature (e.g., Anderson & Dahle, 2009) and our
interviews revealed that different IAFs focus on different
types of audit work (e.g., operational audits, ?nancial
audits, external audit support, and management’s
requests) and that management can signi?cantly affect
the type of work performed by and the results reported
by the IAF. In particular, 4 of 11 (36%) of our interviewees
described management’s involvement and direction in the
areas of audit focus and the scoping of particular audits.
For example, CAE9 describes how management can direct
and assist in audit work:
‘‘They have a lot of input. They provide color around
areas. They provide suggestions on areas to be audited.
[But] they don’t stop us from auditing areas. We have
free access to any information that we need to audit
17
Abbott et al. (2007) ?nd that in the pre-SOX era, ?rms with strong audit
committees are less likely to outsource routine internal audit activities to
their external audit ?rm. They interpret these results to mean that high
quality audit committees are more effective at managing independence
issues within the IAF. Abbott et al. (2010) ?nd that when audit committees
have greater oversight of the IAF, they are better able to steer internal audit
activities toward performing internal control work than when management
has greater internal audit oversight.
18
Rose et al. (2013) focus on a narrow issue related to the power of the
board of directors to appoint members of management, thereby reducing
senior management’s ability to promote internal auditors into management
functions. While their study shows that empowering the board with this
responsibility further reduces IAF objectivity, this result is not necessarily
generalizable to the broader construct of audit committee effectiveness. We
extend Rose et al. (2013) by examining the broader issue of how overall
audit committee oversight interacts with the systematic rotation of internal
auditors on ?rm-level ?nancial reporting metrics.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 47
an area. . .. they’re real good about, you know, saying
hey, I’d really like you to look into this area.’’
CAE11 similarly reports management’s expectations
play a large role:
‘‘It’s changed over the years, so when I ?rst became the
Chief Audit Executive, I reported to our CFO. . .[then] I
got moved to our [chief legal of?cer]. . .and then move-
d. . .to our CEO, so as those transitions have occurred, so
has really my drive and push to do different things. So
of course when this was a CFO function with my prede-
cessor, the group talked about ?nance stuff. . .’’
The interviews suggest that management’s interests
affect the work performed by the IAF—especially if the
IAF uses a rotational staf?ng model. Thus, if management
expects internal audit to focus on ?nancial reporting qual-
ity, this will operate as a compensating control in that the
internal auditors will be more likely to do so, which we
expect will help ensure higher ?nancial reporting quality.
This leads to our ?nal hypothesis:
H4. Among companies using systematic rotation, those
that more heavily focus internal auditors on ?nancial
matters have higher ?nancial reporting quality.
Archival data and model speci?cation
Sample and data
We use several datasets to test our hypotheses. We
obtain data about IAFs from the GAIN database, gathered
by the IIA. We use data from the Compustat, CRSP, Audit
Analytics, and RiskMetrics databases to obtain the remain-
ing variables. Similar to Messier et al. (2011), we lose 148
?rm-years because of inconclusive data concerning the use
of systematic rotation.
19
Our data requirements result in
353 ?rm-year observations, which correspond to 157 com-
panies in 38 different two-digit SIC code industries from
the years 2000 to 2005.
The IIA GAIN database compiles survey responses from
chief audit executives associated with IIA member organi-
zations, and thus includes a wide range of institutions (e.g.,
publicly-traded companies, private companies, educational
institutions, subsidiaries and divisions within companies,
and governmental institutions). The survey covers various
aspects of internal audit practice and provides benchmark-
ing data for participating companies. The survey changes
slightly from year to year, but none of the questions
included in this study changed over our time period.
20
The IIA does not reveal participating companies’ identi-
ties. Thus, we match several self-reported ?elds in the
survey with data items in Compustat to include appropri-
ate control variables in our study. Speci?cally, following
Prawitt et al. (2009), we match on self-reported total
assets, total revenues, and operating industry to identify
companies. We include all companies for which we can
match identically all three metrics in a particular year
and then use the unique identi?er in the IIA data to iden-
tify subsequent or previous ?rm year responses.
21
We measure ?nancial reporting quality using
Accounting Risk, a proprietary measure developed by
Audit Integrity. Audit Integrity uses publiclyavailable ?nan-
cial data to estimate the likelihood that reported ?nancial
information includes elements that are intentionally mis-
leading or fraudulent (Audit Integrity, 2005). Accounting
Risk is the output of a proprietary model that evaluates pub-
lic companies’ ?nancial reports and independently assesses
the risk of misreporting by identifying suspicious patterns
in accounting. Thus, Accounting Risk is an ex ante estimate
of the risk that companies are engaging in inappropriate
or aggressive ?nancial reporting.
22,23
The Accounting Risk
measure, scaled from 0 to 100, is decreasing in risk (a value
of 100 suggests very low risk). For ease of interpretation
and to be consistent with prior research (Price et al., 2011),
we invert the scale so it is increasing in risk (a value of 100
suggests very high risk). A positive relation between system-
atic rotation and Accounting Risk (H1) suggests that system-
atically rotating internal auditors into management positions
is associated with lower ?nancial reporting quality.
Price et al. (2011) provide evidence supporting the con-
struct validity of the Accounting Risk measure. Speci?cally,
they ?nd that the measure is as good as or superior to a
variety of academic risk measures for predicting SEC
enforcement actions, irregular restatements (Hennes,
Leone, & Miller, 2008), and lawsuits related to accounting
malfeasance.
Addressing selection bias
Because organizations choose whether to use systematic
rotation, selection bias is a concern in our study.
Researchers have identi?ed several econometric techniques
for mitigating the effects of selection bias (see summaries in
Francis, Lennox, & Wang, 2010; Larcker & Rusticus, 2010;
and Tucker, 2010). We use a Heckman self-selection model
for several reasons: (1) selection bias due to unobservable
omitted variables is the chief concern in our setting; (2)
?rms’ choice to use rotational staf?ng models is binary;
(3) we identify an exogenous, independent variable in the
19
The IIA survey asks respondents if they systematically rotate staff and
the CAE position and gives them four options from which to choose. These
options include using staff and CAE positions as rotational, career,
rotational moving to career, and career moving to rotational. Consistent
with Messier et al. (2011), because it is not possible to discern the degree of
‘‘movement’’ for the latter two categories, we exclude these ?rm-years
from our study.
20
After 2005, the IIA no longer included the question on systematic
rotation as a staf?ng model.
21
Prawitt et al. (2009) report that this matching procedure correctly
identi?es ?rms in the IIA’s database.
22
Data relating to companies’ IAFs are not directly used in the calculation
of Audit Integrity’s risk measure. Ideally we would also examine ex post
measures of accounting risk (e.g., SEC enforcement actions, restatements,
etc.). However, similar to Prawitt et al. (2012), there is minimal intersection
of these type events with our data; therefore, we are unable to perform an
ex post analysis.
23
Accounting Risk is calculated based on the following inputs: (1)
expense recognition, (2) revenue recognition, (3) high risk events, and (4)
asset and liability valuation. Audit Integrity measures each component
using the following metrics: (i) the percentage change from the prior year,
(ii) number of standard deviations from the industry average, and (iii)
volatility over two years (Price et al., 2011).

?rst stage model that we appropriately exclude from the
independent variables in the second stage model; and (4)
from a practical perspective, the relatively small sample of
companies with IAF data makes it dif?cult to identify good
matches using propensity score matching.

(See Appendix B for variable de?nitions.)
In Eq. (1), the dependent variable is the dichotomous
choice variable, Rotate, which equals 1 if the ?rm uses sys-
tematic rotation and 0 otherwise. The Heckman selection
model requires us to identify an exogenous independent
variable in the ?rst stage model that we can appropriately
exclude from the second stage model (Francis et al., 2010).
We include MeanIndRotate, which represents the industry
average use of rotational staf?ng models (excluding the
company itself). Companies commonly benchmark their
IAF practices basedon industry peers; thus, if industry peers
systematically rotate internal auditors into management
positions, we posit that a company will be more likely to
do so as well. Thus, we expect a positive coef?cient on
MeanIndRotate. It is appropriate to exclude MeanIndRotate
from the second stage models explaining Accounting Risk
because there is no reason to expect that the industry
benchmark for using a rotational staf?ng model will affect
an individual company’s accounting risk.
Our prediction model also includes a number of addi-
tional variables. First, we control for two other internal
audit characteristics that might be associated with the
choice to use systematic rotation by including
IACompetence and Outsource. We include IACompetence
because Messier et al. (2011) provide univariate evidence
that systematic rotation is negatively associated with inter-
nal audit quality. We also include a dichotomous measure
to capture whether companies outsource work of the IAF
to a third party (Outsource) because it is unclear whether
?rms that use systematic rotation are likely to outsource
IA positions. Outsource is equal to 1 if a company outsources
any or all of its IAF to a third party, and 0 otherwise.
24
To
control for the effect of various corporate governance mech-
anisms, we include the effectiveness of the audit committee
(AuditCommittee), two measures of external auditor quality
(AuditSpecialist and AuditFee), and management’s power over
the board of directors (Gindex) (Gompers, Ishii, & Metrick,
2003). We expect higher quality corporate governance will
be negatively associated with the systematic rotation.
We control for size (Assets), leverage (Leverage), com-
plexity (Complexity), market-to-book (MB), age (Age), and
an indicator for companies listed on the New York Stock
Exchange (NYSE), as each of these ?rmcharacteristics could
affect the decision to use systematic rotation (Messier et al.,
2011). We also include six industry dummy variables rep-
resenting one-digit SIC code industries. We control for year
effects by including indicator variables for each ?scal year.

AR is the accounting risk measure described previously.
Rotate is a dichotomous variable measuring whether a
company uses systematic rotation. A positive coef?cient
on this variable would indicate that, consistent with
Hypothesis 1, companies that use systematic rotation have
higher accounting risk than companies that do not.
Audit committees are monitors of the ?nancial reporting
process. Therefore, we control for the CAE reporting to the
audit committee (CAEAC), effectiveness of the audit com-
mittee (AuditCommittee), and audit committee diligence
(MeetOften). We expect a negative coef?cient for CAEAC,
AuditCommittee, and MeetOften. To control for the expertise
of the IAF, we include IACompetence and QAR which mea-
sure things such as certi?cations, experience, and training
(see Appendix B for full discussion) and whether the IAF
has had a recent quality annual review. We also control
for turnover within the IAF (Turnover) as turnover may
decrease the monitoring ability of the IAF, thus increasing
accounting risk. Furthermore, IAFs that use systematic rota-
tion are likely to have higher turnover (Messier et al., 2011),
and we want to evaluate whether systematic rotation is
what is associated with accounting risk while holding con-
stant the effects of turnover. Prawitt et al. (2012) also
demonstrate that outsourcing work of the IAF can affect
24
In untabulated analyses, we include measures of whether the out-
sourced service provider was the external auditor (Prawitt et al., 2012). Our
inferences are qualitatively similar to those reported when we include
these alternative measures and therefore, for parsimony, we report our
results with the single outsourcing measure. For purposes of this paper, we
de?ne qualitatively similar to mean the results are of the same statistical
signi?cance (statistically signi?cant p-value < 0.05, marginally signi?cant
p-value < 0.10) and of the same sign. We also note that in our sample, the
average amount of the IAF that is outsourced to a third party is 9.4%
(median of 3.0%). There is one ?rm-year observation that outsourced 100%
of the work. At the 95th percentile, 40% of the work is outsourced. Since
only a small part of the IAF is outsourced, there are many positions that are
still available for systematic rotation.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 49
accounting risk, thus we include a measure of outsourcing
in our model (Outsource).
In addition, we expect a negative association between
accounting risk and external auditor quality
(AuditSpecialist), but a positive association between
accounting risk and external audit fees (AuditFee)
(Charles, Glover, & Sharp, 2010). For Gindex, we expect a
positive relation with accounting risk as higher values of
Gindex suggest greater management power and thus
weaker corporate governance.
The other control variables are relatively standard in
the literature, so we omit their detailed descriptions (for
detailed discussion see Beneish, 1997; Dechow, Sloan, &
Sweeney, 1996; Jones, Krishnan, & Melendrez, 2008;
Matsumoto, 2002; Menon & Williams, 2004; Prawitt
et al., 2012; Richardson, Tuna, & Wu, 2002; Romanus,
Maher, & Fleming, 2008). Lambda is the inverse Mills’ ratio
computed from Eq. (1), which we include in order to con-
trol for the effects of self-selection bias due to unobserv-
able factors. As a reminder, MeanIndRotate, is the
independent variable from Eq. (1) that we exclude from
Eq. (2).
25
We do not tabulate coef?cient estimates for the
industry and year indicators as we have no ex ante predic-
tion about whether the risk of fraudulent or inappropriate
accounting transactions differs by industry or over time.
Finally, we cluster standard errors by company.
26
Testing effects of compensating controls
To test Hypothesis 2, we rerun Eq. (2) splitting Rotate
into three variables: RotateCAE is a dichotomous variable
indicating whether the chief audit executive position is
systematically rotated, RotateEmp is a dichotomous vari-
able indicating whether only staff positions are systemati-
cally rotated, and RotateBoth is a dichotomous variable
indicating whether both staff positions and the CAE posi-
tion are systematically rotated. H2 posits that the coef?-
cient on RotateCAE will be greater than the coef?cient on
RotateEmp, which we test using an f-test.
To test H3 and H4 we estimate the following cross sec-
tional regression model:

(See Appendix B for variable descriptions.)
Eq. (3) includes one new variable and several interac-
tion terms. The new variable, MGMTFocus, is a dichoto-
mous variable taking the value of one if management
expects internal audit to focus on both risk assessments
and internal consulting on ?nancial matters (versus a focus
on compliance (laws and regulations) or internal consult-
ing on operational matters).
To test H3, we interact Rotate with three separate mea-
sures capturing audit committee oversight. These three
audit committee variables capture both audit committee
effectiveness characteristics (AuditCommittee) and activi-
ties (CAEAC and MeetOften). We expect ?rms with strong
audit committee oversight to have effective audit commit-
tee characteristics, to direct the CAE to report to the audit
committee, and to meet more often with the CAE. A nega-
tive coef?cient on the interaction terms Rotate ? CAEAC;
Rotate ? AuditCommittee; and Rotate ? MeetOften would
support H3. The relationship between the IAF and the audit
committee is likely multi-faceted, so we cannot ex ante
predict which variable is the most important factor
impacting the relation or whether all should be signi?cant.
To test H4, we interact MGMTFocus and Rotate. A nega-
tive coef?cient on this interaction would suggest that, con-
sistent with H4, management’s expectations that internal
auditors focus on ?nancial work improves ?nancial report-
ing quality for ?rms that use systematic rotation.
Results
Descriptive statistics and univariate comparisons
Table 3, Panel A presents descriptive statistics. For brev-
ity, we highlight select variables here. Overall, 82% of sam-
ple ?rm-years report using systematic rotation. Companies
that use this practice are most likely to systematically
rotate staff positions (RotateEmp = 0.42). In addition, the
sample consists of large companies that are not highly
leveraged or overly complex. Finally, our sample ?rms
appear to have reasonably competent IAFs as the
IACompetence exhibits only a one point difference between
the 25th and 75th percentiles. In Table 3, Panel B we pro-
vide a correlation matrix.
Table 4 presents the results of the ?rst stage model that
explains the choice to systematically rotate internal audi-
tors. As expected, the use of systematic rotation by a com-
pany’s industry peers is positively related to a company’s
decision to use systematic rotation (i.e., MeanIndRotate is
positive and p-value < 0.01). In addition, the more compe-
tent the IAF, the less likely it will be to use systematic rota-
tion (p-value < 0.01). Outsourcing some of the IAF is
positively associated with systematic rotation
(p-values < 0.05).
27
Consistent with Messier et al. (2011),
25
Our inferences are robust if we include any or all of the additional
control variables from Eq. (2) in Eq. (1) (e.g., return, loss, etc.).
26
An alternative to including year ?xed effects is to cluster our standard
errors by both ?rm and year. However, given the small number of years in
our sample period, year ?xed effects are preferable (Peterson, 2009).
27
We provide two possible explanations for the positive relation between
outsourcing and systematic rotation. First, a company that uses systematic
rotation may choose to use internal auditors in tasks that develop their
management skills, while purchasing outsourced services in areas that are
not as important for management. Second, the head of internal audit,
perhaps in conjunction with the audit committee, is aware that IAFs that
use systematic rotation might be missing some internal audit skill sets;
thus, they may purchase specialized skill sets using outsourcing arrange-
ments. Regardless, our statistical analyses control for these possibilities;
thus, our results are not confounded by the association between out-
sourcing and the use of systematic rotation. We encourage future research
to examine this issue more closely.

companies that use systematic rotation have higher external
audit fees (p-value < 0.05). From this model, we compute the
inverse Mills’ ratio and use it to control for selection bias in
the remaining models.
28
Hypothesis testing
H1 predicts that companies that use systematic rotation
will have lower ?nancial reporting quality, which we oper-
ationalize as higher accounting risk. The results, presented
in Table 5, Panel A show that the coef?cient estimate for
Rotate is positive and statistically signi?cant
(p-value < 0.01). This result supports H1 and suggests that
companies that systematically rotate their internal auditors
have greater accounting risk (i.e., lower ?nancial reporting
quality) than companies that do not use systematic rota-
tion. Of our two IAF expertise measures, we ?nd that QAR
is negative and statistically signi?cant (p-value < 0.05)
while IACompetence is not signi?cant (p-value > 0.10). Of
the other control variables, Turnover, Outsource,
AuditSpecialist, Assets, Complexity, Loss, and Return are statis-
tically signi?cant, all in the direction predicted
(p-values < 0.10). Our inferences about the association
between systematic rotation and accounting risk are unli-
kely to be affected by selection bias due to unobserved com-
pany characteristics because the model includes the inverse
mills ratio, Lambda, from the Rotation prediction model.
Panel B of Table 5 shows the results of tests of H2
which examine whether companies that systematically
rotate the chief audit executive position have higher
accounting risk than companies that only rotate staff
internal audit positions (H2). The test of RotateCAE =
RotateEmp shows that the coef?cient on RotateCAE is
higher than the coef?cient on RotateEmp (p-value < 0.05),
supporting H2. We also ?nd that systematically rotating
both the chief audit executive position and staff positions
is associated with higher accounting risk than using just
staff positions (p-value < 0.05). Thus, as our interview
data suggest, systematically rotating the head of internal
audit position is particularly troublesome in its effects
on ?nancial reporting quality. We also note that all three
of the Rotate variables are positive and statistically signif-
icant (p-values < 0.01); thus, using only rotating staff
positions is not a cure-all—it is still associated with higher
accounting risk.
In Table 6, we present our tests of H3 and H4. H3 posits
that a strong audit committee mitigates the negative
?nancial reporting effects of using systematic rotation.
The negative coef?cient on Rotate ? AuditCommittee
indicates that a more effective audit committee is associ-
ated with a reduction in the incremental accounting risk
from using systematic rotation (p-value < 0.05). Having
the head of internal audit report to the audit committee
and having more frequent meetings are directionally
consistent but not statistically signi?cant at traditional
levels (p-values = 0.109 and 0.120, respectively).
However, having a strong audit committee is not suf?cient
to completely mitigate the negative effect of using
systematic rotation because the sum of Rotate + Rotate ?
CAEAC + Rotate ? AuditCommittee + Rotate ? MeetOften = 0 is
still positive (p-value < 0.01).
In H4, we posit that if management asks internal
auditors to place greater focus on improving ?nancial
reporting, systematic rotation will be more likely to reduce
?nancial reporting risk. The results of our test support this
hypothesis in that the Rotate ? MGMTFocus interaction is
negative and moderately signi?cant (p-value < 0.10).
Again, management’s expectation that the IAF focus on
?nancial reporting is not suf?cient to completely
mitigate the negative effect of using systematic rotation,
because Rotate + Rotate ? MGMTFocus = 0 is still positive
(p-value < 0.01).
We examine whether the combination of a strong audit
committee and management focus on having internal audit
improve ?nancial reporting completely mitigates the nega-
tive effect of using systematic rotation by testing whether
the sum of Rotate + Rotate ? MGMTFocus + Rotate ?
CAEAC + Rotate ? AuditCommittee + Rotate ? MeetOften = 0.
This sum is not statistically different from zero
(p-value > 0.10) suggesting that the combination of both a
strong audit committee and management focus on ?nancial
reporting eliminates the negative ?nancial reporting effects
of using systematic rotation.

Audit committee effectiveness is not signi?cant in explaining the
choice to use systematic rotation. This result is somewhat surprising given
prior research showing that the audit committee appears to distinguish
between outsourcing arrangements that are more or less likely to produce
economic bonding (Abbott et al., 2007). However, our result is based on a
relatively small sample, and the audit committee does not always decide
whether to systematically rotate internal auditors (this decision can also be
made by the CEO, the CFO, or the CAE). Several of our interviewees
indicated that the decision to use a rotational staf?ng model for the IAF was
made by other individuals or groups within the organization. For example,
in some companies the decision is made by executive management (e.g.,
CFO), and often, it is driven by the CAE him/herself.
52 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Taken together, the results suggest that systematically
rotating internal auditors into management positions can
impair the IAF’s effectiveness in monitoring the ?nancial
reporting process. One such negative consequence of using
systematic rotation is increased accounting risk as com-
pared to companies that do not use systematic rotation.
This means companies that use systematic rotation have
an increased likelihood of intentional misstatement and/or
fraud in their ?nancial statements. However, a strong audit
committee and management’s directive to the IAF to focus
on ?nancial reporting issues can serve as compensating
controls that can mitigate the extent to which systematic
rotation increases accounting risk.
Robustness tests
As two alternative tests of H1, we repeat the same anal-
ysis in Table 4, Panel A, using alternative dependent vari-
ables. Instead of Accounting Risk, we use Dechow, Ge,
Larson, and Sloan’s (2011) fraud risk score (F-score) and
an abnormal accruals measure based on Dechow, Sloan,
and Sweeney (1995). F-score was designed to identify the
same types of egregious accounting irregularities as Audit
Integrity’s Accounting Risk measure. Consistent with our
results, for both alternative dependent variables, we
observe a positive and signi?cant coef?cient
(p-value < 0.05) on Rotate. Thus, our results for H1 are
robust using alternative measures of the risk of ?nancial
misreporting.
We also retest H2 using the alternative dependent vari-
ables. Rotate CAE, Rotate Both, and Rotate Emp remain pos-
itively associated with accounting risk (p-values < 0.05),
but the differences between variables are no longer statis-
tically signi?cant. We also repeat our tests of H3 and H4,
using the alternative dependent variables. H3 is supported
when we use the F-score (p-value < 0.05) but is not statis-
tically signi?cant when we use the abnormal accrual mea-
sure (p-value = 0.145). Similarly, the results for H4 hold
with the F-score measure (p-value < 0.05), but not with
the abnormal accrual measure. Overall, the results are rea-
sonably robust to using noisier proxies for ?nancial report-
ing quality (Price et al., 2011).
A potential alternative explanation for H1 is that our
accounting risk measure is simply picking up the external

auditor’s pricing of reduced audit quality or the external
auditor’s reliance on the IAF (Hribar, Kravet, & Wilson,
2014; Messier et al., 2011). To control for this possibility,
we include as a control variable the unexpected audit fee
measure developed by Hribar et al. (2014). This measure
does not load signi?cantly in our tests, and our inferences
remain robust.
Conclusions
In this paper, we examine whether the practice of sys-
tematically rotating internal auditors into management
positions (i.e., systematic rotation) is associated with lower
?nancial reporting quality. We also investigate compensat-
ing controls, which we derive from interviewing practicing
heads of internal audit and audit committee members,
which can strengthen the IAF’s capacity and willingness
to detect and prevent low quality ?nancial reporting and
thereby mitigate this negative relation. Consistent with
our causal predictions, we ?nd that systematic rotation is
associated with lower ?nancial reporting quality, indicat-
ing that companies that employ this practice may be more
susceptible to misleading or fraudulent ?nancial reporting
than companies that do not use this practice. We also ?nd
that several key compensating controls that provide over-
sight to the IAF do moderate this negative effect. That is,
the negative relationship between using systematic rota-
tion and ?nancial reporting quality is reduced if the follow-
ing compensating controls, are used: (1) only staff internal
audit positions (not CAE) are rotated, (2) there is a more
effective audit committee, or (3) management asks inter-
nal audit to have a greater role in the ?nancial reporting
process. Further, using the compensating controls together
eliminates the negative association between systematic
rotation and impaired ?nancial reporting quality.
These results inform practitioners and scholars about
whether and how the IAF impacts organizations. The
IIA’s de?nition of internal auditing states that internal
auditors should be independent and ‘‘add value by
improving an organization’s operations, risk management,
control, and governance processes’’ (2011a). Our results
suggest that systematic rotation, without the implemen-
tation of appropriate compensating controls, may impair
the IAF’s ability to monitor ?nancial reporting quality.
Internal audit standard setters and practitioners, as well
as others interested in corporate governance, should ?nd
these results useful in helping to improve the IAFs ability
to ful?ll its charge.
Our results contribute to the existing literature on sys-
tematic rotation (i.e., research on using the IAF as a MTG)
in several important ways. First, ours is the ?rst study to
investigate the effect of this practice on ?nancial reporting
quality. While prior research has examined its effects on
objectivity (Rose et al., 2013) and perceived objectivity
(Messier et al., 2011), we use archival data to test and ?nd
that these effects extend beyond the internal auditor to the
impairment of ?nancial reporting quality. Second, we
advance the literature by examining several key compen-
sating controls that can improve the IAF’s willingness and
capacity to prevent and/or detect low quality ?nancial
reporting. When organizations implement these control
practices, which provide various forms of oversight to the
IAF, the negative effect of systematic rotation diminishes.
When the controls are used together, the negative effect
can be eliminated. Third, our interview data provides
insights into the practice of systematic rotation including
its bene?ts and challenges. Prior research has not consid-
ered the bene?ts of systematic rotation and further explo-
ration is warranted to better understand how it helps the
IAF add value to the organization.

The results of this study are subject to several limita-
tions that suggest avenues for future research. First, archi-
val research is limited in its ability to test causal relations.
The model we develop from interviewing practitioners
suggests factors that can affect the objectivity and compe-
tence of internal auditors. Researchers using experimental,
survey, case study, interview, and other methods may be
able to shed additional light on this model and our ?nd-
ings. For example, experiments can be used to more
directly test whether objectivity and competence mediate
the relation we observe between systematic rotation and
?nancial reporting quality.
29
Using complementary
research methods can triangulate research ?ndings and
improve our understanding of how the IAF affects ?nancial
reporting quality.
Second, we include in our initial model and test three
key compensating controls identi?ed by the CAEs we
interviewed. However, the CAEs also mentioned other
important compensating controls that we were not able
to test due to data limitations (e.g., hiring practices,
supervisory review practices). Future research should
explore whether and how these other controls may miti-
gate the risks of rotating internal auditors into opera-
tional management positions. For example, experimental
methods may be useful to determine whether different
methods of workpaper review can mitigate the risk of
impaired independence/objectivity.
Third, due to data availability constraints, our analysis
is limited to data collected between 2000 and 2005.
Although this was a tumultuous time for publicly traded
corporations, there is no reason to believe the events of
this time period would be correlated with the use of the
systematic rotation. In particular, the changes that
occurred during this period (e.g., the implementation of
SOX) would likely have affected companies that do and
do not rotate internal auditors in similar ways. We believe
examining practices associated with internal auditing and
how companies can improve their IAFs to ensure high
quality corporate governance is an important area for
future research.
Overall, this paper makes an important contribution to
research and practice by demonstrating that although sys-
tematic rotation of internal auditors into management
positions is negatively associated with ?nancial reporting
quality, the negative effects can be mitigated with
appropriate compensating controls. Most of the prior liter-
ature has identi?ed risks to internal auditors’ objectivity
and independence resulting from systematic rotation, but
has not considered whether control conscious organiza-
tions can implement the appropriate policies, procedures,
and oversight to effectively mitigate these risks.
Additionally, this paper demonstrates to researchers that
combining interview and archival data sources can pro-
duce interesting insights into important accounting mat-
ters that would not be attainable using only archival data.

We used the following interview protocol to guide our
interviews.

f. Reporting lines
2. Systematic rotation of internal auditors into
management:
a. Do you use systematic rotation? (why or why not?)
b. Who makes the decision to use systematic
rotation?
c. Do auditors start in IA and rotate into the company
or can they come into IA after holding an opera-
tional position?
d. Which employees rotate out (All? Some? Staff only
– i.e., not CAE)?
e. Who decides who gets hired out of internal audit?
f. What is the time frame for rotation?
g. Is there a special skill set needed for rotation?
h. Do rotating internal auditors do different work
than other (career) internal auditors? (e.g., do they
only focus on consulting?)
3. Bene?ts & costs (risks) of systematic rotation:
a. What are the bene?ts of systematic rotation?
i. For the IA department/organization/rotating
auditor?
b. What are the risks of systematic rotation?
i. For the IA department/organization/rotating
auditor?
c. Financial reporting quality:
i. Does internal audit impact FRQ? (Why or why
not?)
ii. How (& why) does systematic rotation impact
this effect on FRQ?
d. Competence:
i. How does systematic rotation impact the com-
petence/expertise of internal auditors?
ii. How does systematic rotation impact the attrac-
tion of talent to internal audit?
29
We do not perform mediation analysis examining the effect of
systematic rotation on objectivity and competence, and then their effects
on FRQ because of the limitations of the empirical proxies for competence
and objectivity that we would have to employ. In particular, the proxies for
competence used in prior literature do not capture the nuances of how
systematic rotation affects competence as described by our interviewees
(e.g., enhanced knowledge of operations, etc.). Further, because objectivity
is an unbiased mental attitude, there are no empirical proxies for the
auditors’ state of mind. Prior research has used chief audit executive
reporting structure (i.e., IAF reporting to the audit committee versus
management) as a proxy for objectivity. However, our interviews suggest
that internal auditor objectivity is still subject to impairment despite
procedural controls aimed at ensuring independence as described in the IIA
Standards (such as reporting structure). Therefore, we include this measure
in our model as a compensating control and do not use it to proxy for
objectivity.

higher scores now indicate more risk).

We de?ne industry specialist auditor in a similar fashion to Mayhew
and Wilkins (2003) and Knechel, Naiker, and Pacheco (2007): an external
audit ?rm is considered the industry specialist (AuditorSpecialist = 1) if
the ?rm provides within-industry market share 30% greater than if the
audit ?rms were to split the industry evenly among themselves. We
measure within-industry market share using two-digit SIC code industry
listings. We use the threshold of 30% as industry specialists based on prior
research (e.g., Knechel et al., 2007; Mayhew & Wilkins, 2003). We note
that studies that examined questions during times that there were Big 8
and Big 6 audit ?rms in existence used thresholds of 15% (Krishnan, 2003)
to 20% (Dunn & Mayhew, 2004). Auditing ?rms that provide a substantial
portion of the auditing to an industry are likely to develop specialized
skills that enable them to perform more effective audits.

A report from the Institute of Internal Auditors ?nds that a majority of Fortune 500 com-
panies systematically rotate internal auditors out of the internal audit function and into
operational management (IIA, 2009a). We use semi-structured interviews with 11 chief
audit executives and 2 audit committee chairmen to develop an initial framework focusing
on how this practice affects ?nancial reporting quality. We then test these associations
with archival data and ?nd that companies that use a rotational staf?ng model for the
internal audit function have signi?cantly lower ?nancial reporting quality than companies
that do not. However, we ?nd that several compensating controls identi?ed from the inter-
views (e.g., consistency of IAF leadership or supervision, audit committee oversight, and
management oversight and direction) can reduce this adverse ?nancial reporting effect.
We conclude that companies should consider the potential costs of using a rotational staff-
ing model in the internal audit function and, if adopting this practice, should ensure the
appropriate compensating controls are in place to mitigate such costs.

Introduction
Approximately two-thirds of Fortune 500 companies
report that they systematically rotate their internal audi-
tors into management positions outside of internal audit
(IIA, 2009a), this practice potentially causes the internal
audit function (IAF) to be used or viewed as a training
ground for future managers (IIA, 2013). This practice is
somewhat perplexing given evidence from prior research
suggesting it diminishes internal auditors’ objectivity
(Messier, Reynolds, Simon, & Wood, 2011; Rose, Rose, &
Norman, 2013). We extend prior research on the effects
of systematically rotating internal auditors into opera-
tional management by conducting interviews with chief
audit executives and audit committee chairpersons to
develop an initial framework of how this practice is
thought to impact ?nancial reporting outcomes. We thenhttp://dx.doi.org/10.1016/j.aos.2015.05.004

use this initial framework to guide an archival analysis that
tests for the presence of key associations between such
rotation and ?nancial reporting quality.
The IAF is required to evaluate the risk exposure and
control effectiveness of the ?nancial reporting system
(IPPF, 2012). In addition, internal audit is expected to help
prevent and detect fraudulent ?nancial reporting (IIA,
2009b; IPPF, 2012) and otherwise constrain aggressive
?nancial reporting (KPMG, 2003; Prawitt, Sharp, & Wood,
2012; Prawitt, Smith, & Wood, 2009; Ege, 2015; Norman,
Rose, & Rose, 2010).

However, internal audit functions use a variety of staff-
ing models to ful?ll their responsibilities, including a range
of systematic rotational programs. Three common types of
rotational programs are: (1) hiring new internal auditors
from outside of the organization with the expectation that
they will spend a (preset) amount of time in internal audit
before being promoted into an operational management
position, (2) bringing operational personnel into internal
audit from within the company for a preset amount of time
on their path to operational management, and (3) sending
‘‘career’’ internal auditors into the organization for a brief
period of time to experience speci?c operational processes
before returning to internal audit. While this spectrum of
rotational programs exists in practice, prior academic liter-
ature has focused on the ?rst two types of programs and
examined how internal auditors’ ultimate goal of obtaining
a management position outside of internal audit likely
impacts his/her effectiveness as an internal auditor. Both
academics and practitioners refer to these types of rota-
tional programs as ‘‘management training grounds’’ (i.e.,
MTGs) because one of their main purposes is developing
future managers’ skills by working in internal audit (e.g.,
Burton, Starliper, Summers, & Wood, 2015; Ege, 2015;
IIA, 2013; Messier et al., 2011; Rose et al., 2013).
We posit that speci?c types of rotational programs have
the potential to reduce ?nancial reporting quality.
Consistent with prior research, we focus on the systematic
rotational programs that result in internal auditors later
obtaining management positions because these practices
are most prevalent and have the potential to impair ?nan-
cial reporting quality. Hereafter, we refer to these practices
as ‘‘systematic rotation.’’ This study does not focus on the
third type of rotational model, which sends career auditors
into operations to gain expertise before returning to inter-
nal audit, because that type of rotational program unlikely
poses the same risks to objectivity as the two other models.
We investigate whether using systematic rotation mod-
els in the IAF affects ?nancial reporting quality in two
stages. One, we draw from prior literature on external
auditor reliability (e.g., DeAngelo, 1981; Taylor, DeZoort,
Thomas, & Munn, 2003) and internal audit quality (e.g.,
Messier et al., 2011; Prawitt et al., 2009; Rose et al.,
2013), as well as regulatory guidance on internal auditor
independence and objectivity (IIA, 2001; IPPF, 2012) and
external auditors’ reliance on internal auditors (e.g., SAS
No. 128, No. 65; ISA 610; AS 5) to guide a set of interviews
with 11 chief audit executives (CAEs) and 2 audit commit-
tee chairmen. Each interviewee provides insights about the
use of systematic rotational programs in his/her organiza-
tion, including the potential costs and bene?ts of system-
atic rotation. By integrating the results of these
interviews with themes in existing literature and regula-
tory guidance, we develop an initial framework that we
test using archival data.
From the interviews and from prior research, we posit
that, in isolation, systematic rotation is likely to impair
?nancial reporting quality. We then advance the theory
and literature on this subject by examining whether com-
pensating controls focused on IAF oversight mitigate the
adverse effect on ?nancial reporting quality. In particular,
our initial framework includes three compensating con-
trols described by our interviewees that we can test: (1)
consistency of IAF leadership or supervision, (2) audit com-
mittee oversight, and (3) management oversight and direc-
tion. Prior research has not identi?ed these potential
compensating controls; however, our interviewees believe
these controls mitigate the potential impairment of inter-
nal auditors’ objectivity and competence that likely arises
when systematic rotational programs are used, such that
the bene?ts of the practice outweigh the risks.
2
Two, we conduct archival tests using data collected by
the IIA to examine the effects of systematic rotation on
?nancial reporting quality. This proprietary database rep-
resents one of the most complete sets of archival internal
auditing data that currently exists. The data identify com-
panies that use systematic rotation, other internal audit
characteristics that help control for internal audit exper-
tise, audit committee characteristics and activities, and
other possible determinants of ?nancial reporting quality,
such as ?rm governance mechanisms (e.g., management
and the external auditor). Our proxy for ?nancial reporting
quality is accounting risk, which we de?ne as the risk that
the audited ?nancial statements contain misleading and/or
fraudulent results (e.g., Price, Sharp, & Wood, 2011). We
address selection bias arising from unobservable differ-
ences in companies that do or do not use systematic rota-
tion with a Heckman self-selection model.
Consistent with our framework, we ?nd that use of sys-
tematic rotation is associated with higher accounting risk.
This result suggests that systematic rotation weakens the
effectiveness of internal audit’s monitoring of ?nancial
reporting within the organization. This result is also con-
sistent with the view from prior research that some rota-
tional IAFs operate primarily as a management training
ground, at the expense of the effectiveness of traditional
internal audit activities.
However, consistent with our predictions, other organi-
zations implement compensating controls that mitigate
this negative relation. Speci?cally, organizations that (1)
rotate only staff internal audit positions (e.g., not the head
1
In the most recent Comprehensive Body of Knowledge (CBOK) survey
conducted by the Institute of Internal Auditors (IIA), approximately 72% of
respondents indicate that their IAF performed audits of ?nancial risks and
71% report that they perform fraud investigations, representing the third
and fourth most commonly performed activities, respectively.
2
While not the focus of this paper, our interviewees also described
several important bene?ts of using rotational programs. We include
insights related to these bene?ts, when relevant, throughout the paper
and provide a list of bene?ts in Table 2.
38 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
of internal audit), (2) have more effective audit commit-
tees, or (3) have management who directs internal audit
to focus on ?nancial reporting (as opposed to operational
or IT audits) are able to reduce the negative ?nancial
reporting effects associated with systematic rotation of
internal auditors into management positions. Further, at
least in this data, when all three types of compensating
controls are present, the negative association between sys-
tematic rotation and ?nancial reporting quality is elimi-
nated. Thus, our results suggest that control-conscious
organizations can use compensating controls to prevent
systematic rotation from reducing ?nancial reporting
quality.
Our study contributes to the literature in several ways.
First, our interviews with CAEs and audit committee chair-
persons identify important institutional details about
using systematic rotation. Interviewees describe many
bene?ts of the practice (e.g., helps attract and retain talent,
improves organizational expertise with the IAF), which
helps explain why so many organizations use systematic
rotation despite potential negative consequences. Our
interviews also identify control practices that companies
use to reduce the risk of impaired IAF objectivity and com-
petence. These institutional details allow us to develop and
re?ne an initial framework of the effect of systematic rota-
tion on ?nancial reporting quality, and they guide our
archival analysis.
Second, we complement and extend prior research by
showing that systematic rotation of internal auditors into
management positions is associated with higher account-
ing risk. Complementing experimental evidence from prior
research suggests that systematic rotation can reduce
internal auditors’ objectivity and external auditors’ percep-
tions of internal audit objectivity (Messier et al., 2011;
Rose et al., 2013), archival associations reported herein
are consistent with our framework’s prediction, i.e., these
rotations can impair internal auditors’ objectivity to the
point of lowering ?nancial reporting quality. Further, these
associations obtain despite compensating work that may
be performed by the external auditor.
Third, in further tests of our framework, however, we
test several compensating controls described by our inter-
viewees, which moderate the negative effect of systematic
rotation on ?nancial reporting quality. These compensat-
ing controls provide various oversight mechanisms within
the company intended to improve the IAF’s willingness and
capacity to prevent and/or detect low quality ?nancial
reporting. This aspect of our study builds on Rose et al.
(2013), who examine whether giving directors power over
the appointment of senior managers in?uences the adverse
effect of systematic rotation; however, Rose et al. (2013)
do not investigate the broader issue of corporate gover-
nance strength, such as audit committee oversight and
effectiveness.
3
In addition, prior research has not examined
IAF leadership consistency or management’s direction for
the IAF as compensating controls.
Finally, we contribute to the literature and to practice
by providing evidence on the effects of using the CAE posi-
tion as a rotational position. Many of our interviewees
expressed concerns about internal audit competence and
objectivity when the head of internal audit is a rotational
position, and our archival analysis con?rms that rotating
the head of internal audit is associated with low ?nancial
reporting quality. The results of our analysis inform the
on-going debate among practitioners regarding the appro-
priateness of this practice. Overall, our results add to the
limited prior literature on how the IAF affects its organiza-
tion’s economic, operational, and ?nancial reporting
outcomes.
Evidence on the consequences of systematic rotation
will also be interesting to investors, boards of directors,
audit committees, and management. These stakeholders
rely on the IAF to monitor ?nancial reporting, and they
can bene?t from evidence about how systematic rotation
affects ?nancial reporting quality. Furthermore, regulators
and standard setters, such as the IIA, would bene?t from
understanding how these rotational assignments affect
?nancial reporting quality and what organizations can do
to address the potential consequences.
In the next section, we use the literature on internal
auditor quality to begin to develop our initial framework
and develop our hypothesis on the effect of systematic
rotation on ?nancial reporting quality. We then describe
our interview method, after which we use the insights
gained from our interviews to re?ne our initial framework
and develop hypotheses on the moderating effects of three
compensating controls. The section titled ‘Archival data

We report the results of our hypotheses tests in the subse-
quent section and then conclude.
IAF quality and ?nancial reporting quality
The IAF is one of the cornerstones of effective corpo-
rate governance and ?nancial reporting (IIA, 2003;
Gramling, Maletta, Schneider, & Church, 2004, Reding
et al., 2009). By the IIA’s de?nition, internal audit should
bring a ‘‘systematic, disciplined approach to evaluate and
improve the effectiveness of risk management, control,
and governance processes’’ (IIA, 2011a). Standards for
the internal auditing profession af?rm the IAF’s responsi-
bility to monitor ?nancial reporting (e.g., IPPF, 2012) and
help detect and deter fraud (e.g., IIA, 2009b; IPPF, 2012),
as well as reduce related losses (Coram, Ferguson, &
Moroney, 2008; Ege, 2015; KPMG, 2003; Norman et al.,
2010).
Prior academic research similarly has shown that an
effective IAF improves: risk assessments (Asare,
Davidson, & Gramling, 2008; Sarens & De Beelde, 2006),
safeguarding of assets (Beasley, Carcello, Hermanson, &
Lapides, 2000; Coram et al., 2008), earnings quality
(Abbott, Daugherty, Parker, & Peters, 2013; Prawitt et al.,
2009), deterrence of management misconduct (Ege,
2015), internal control strength (Lin, Pizzini, Vargus, &
Bardhan, 2011), audit quality (Prawitt et al., 2012), and
audit ef?ciency (Felix, Gramling, & Maletta, 2001; Pizzini,

2011).
Prior research generally considers internal auditing at
a relatively high level (e.g., an overall composite measure
of internal audit strength) and institutional details of the
internal auditing environment are sometimes overlooked
(Koonce, 2013). Thus, one purpose of this paper is to pro-
vide rich institutional details from interviews with heads
of internal audit (i.e., chief audit executives) and audit
committee chairmen who describe how internal audit is
practiced. We then use these institutional details to
develop an initial framework to guide our archival
analysis.
We begin by reviewing the existing academic research,
practitioner literature, and regulatory guidance on internal
and external auditor reliability. We extract common ele-
ments and to develop an initial framework of factors that
(should) impact the IAF’s effect on ?nancial reporting qual-
ity. In particular, we draw from: (1) The International
Standards for the Professional Practice of Internal
Auditing promulgated by the IIA, which provide the basic
requirements for internal auditing; (2) various external
audit standards that govern how external auditors are to
evaluate IAFs when using their work as part of the external
audit
4
; (3) DeAngelo’s (1981) model describing external
audit quality as a function of auditor technical ability and
independence/objectivity; and (4) Taylor et al.’s (2003)
framework describing external auditor reliability as a func-
tion of expertise, objectivity, independence, and integrity.
5
Although DeAngelo’s model and Taylor et al.’s (2003) frame-
work focus on external auditor quality and reliability,
respectively, the underlying components are relevant to
internal auditors as well.
6
Indeed, Taylor et al. (2003) state
that their framework ‘‘has the potential to clarify responsi-
bilities and guide other critical ?nancial reporting and cor-
porate governance groups, such as internal auditors’’ (264).
Our examination of these sources reveals two impor-
tant commonalities. First, objectivity is central to high
quality auditing. For example, Taylor et al. (2003) argue
that external auditor reliability ‘‘can be achieved only by
the relentless pursuit of objectivity’’ (p. 262). Similarly,
internal audit standards state that ‘‘internal auditors must
be objective in performing their work. . .Objectivity is an
unbiased mental attitude that allows internal auditors to
perform engagements in such a manner that they believe
in their work product and that no quality compromises
are made. . .Objectivity requires that internal auditors do
not subordinate their judgment on audit matters to others’’
(IPPF, 2012, pp. 3–4). Finally, for evaluating internal audi-
tors, AS 5 states ‘‘the auditor should not use the work of
[internal auditors] who have a low degree of objectivity,
regardless of their level of competence.’’
Second, the competence or expertise of internal audi-
tors also is key. Internal audit standards state that ‘‘internal
auditors must possess the knowledge, skills, and other
competencies needed to perform their individual responsi-
bilities’’ (IPPF, 2012, p. 5). ISA 610 (revised) states,
‘‘Competence of the internal audit function refers to the
attainment and maintenance of knowledge and skills of
the function as a whole at the level required to enable
assigned tasks to be performed diligently and in accor-
dance with applicable professional standards’’ (p. 13).
Other external audit standards mirror this language, and
the DeAngelo (1981) model and the auditor reliability
framework (Taylor et al., 2003) suggest expertise is a key
component of external audit quality. In sum, all of the
sources we have reviewed consider objectivity and compe-
tence to be central to high performing IAFs.
7
Importantly, systematic rotation has the potential to
impair the objectivity and competence of the internal audit
function. Although there exists a spectrum of rotational
staf?ng models used by organizations, we followprior liter-
ature and focus on rotational models that result in internal
auditors systematically leaving the IAF for management
positions (e.g., Ege, 2015; Messier et al., 2011). In one such
model, the IAF hires new auditors from outside the com-
pany, promising them a short tenure (e.g., two to three
years) in internal audit followed by the opportunity to
assume management positions within operations.
Alternatively, other organizations populate the internal
audit function with existing operational personnel who
use a short termin the IAF to become knowledgeable about
risk and control before being promoted into other opera-
tional positions.
8
While there are notable differences in
these two rotational staf?ng models, each is likely to have
similar effects on the objectivity and competence of the
internal auditors within them because the internal auditors
are motivated by the ultimate goal of obtaining future
4
We refer to SAS No. 128, Using the Work of Internal Auditors (which
supersedes SAS No. 65, The Auditor’s Consideration of the Internal Audit
Function in an Audit of Financial Statements); ISA 610 (revised 2013), Using
the Work of Internal Auditors; and AS 5, An Audit of Internal Control Over
Financial Reporting that is Integrated with an Audit of Financial Statements. A
signi?cant body of research supports that external auditors follow these
standards when evaluating IAFs (e.g., see Bame-Aldred, Brandon, Messier,
Rittenberg, & Stafaniak, 2013; Glover, Prawitt, & Wood, 2008; Gramling
et al., 2004).
5
Taylor et al. (2003) develop the external auditor reliability framework
which is tested by DeZoort, Holt, and Taylor (2012).
6
Prior research often uses the terms reliability and quality interchange-
ably (e.g., Taylor et al., 2003). Similarly, the terms competence/expertise
and objectivity/independence are also often used interchangeably in the
literature. Differentiating between each of these concepts is beyond the
scope of this paper. Therefore, when discussing prior literature we use the
term(s) used in each speci?c paper and as a result, also use the terms
somewhat interchangeably.
7
Each source also describes other attributes of a high quality IAF. For
example, the internal audit standards suggest the importance of quality
assurance programs and speci?c performance standards (e.g., guidelines of
how to plan, perform the engagement, and communicate ?ndings). External
auditing standards state that the internal auditors’ work must relate to the
external audit, and the external auditor reliability framework focuses on
other factors that increase objectivity, such as integrity and independence.
We retain the simple two-factor model of objectivity and competence to
guide our interviews because objectivity and competence are common
across all sources we reviewed and because other factors often lead to
objectivity and competence (e.g., see discussion in Taylor et al., 2003).
8
Home Depot has publicized its use of systematic rotation to hire new
auditors into the organization from the outside, with the express intent to
go into a business manager role after two years. GE is one of the most
prominent companies to employ systematic rotation to staff the internal
audit department with current operational personnel who intend to
advance to higher positions after a stint in internal audit (Baker, 2010).
Organizations also vary in the extent to which rotating into or out of
internal audit within a certain timeframe is optional (Baker, 2010).

positions outside of the IAF.
9
We consider these two rota-
tional staf?ng models together, which is consistent with
prior literature (e.g., Ege, 2015; Messier et al., 2011; Rose
et al., 2013).
Fig. 1 illustrates the theoretical relationships modeled
in our initial framework of the effect of systematic rotation
of internal auditors on ?nancial reporting quality.
Objectivity
Systematic rotation could impair internal auditors’
objectivity by creating a dependent relationship between
the internal auditors and members of management who
are considering them for promotion (Chadwick, 1995;
Hoos, Messier, Smith, & Tandy, 2014; Wood & Wilson,
1989). As noted in Stewart and Subramaniam (2010), sys-
tematic rotation can induce social pressures and economic
interest threats to the independence and objectivity of the
IAF. In particular, there is the potential for systematic rota-
tion to focus internal auditors on obtaining or performing
future positions outside of the internal audit department,
diminishing their objective assurance over ?nancial report-
ing processes.
10
This potential is consistent with the general conclusion
of prior studies on systematic rotation. Using experiments,
Hoos et al. (2014) and Rose et al. (2013) provide evidence
that internal auditors are less objective given systematic
rotation.
11
Relatedly, Messier et al. (2011) ?nd that external
auditors perceive rotational internal auditors to be less
objective, and that audit fees are higher for companies that
rotate internal auditors into operations. The latter effect is
interpreted as evidence that the external auditors do more
work to compensate for the (perceived) impaired objectivity
of rotational auditors. Taken together, prior literature sug-
gests systematic rotation causes impaired objectivity.
Competence
Systematic rotation could compromise the internal audit
competence of the IAF for several reasons. One, employees
who view internal audit positions as a stepping stone to
management opportunities are less likely than others to
pursue training and certi?cations that would improve their
internal audit competence (Anderson, 2010). Two, the con-
stant rotation out of the IAF diminishes overall IA experi-
ence and expertise relative to models with ‘‘career’’
auditors (Anderson, Christ, Johnstone, & Rittenberg, 2010).
Research examining whether rotational staf?ng models
affect internal auditors’ competence is less prevalent than
examinations of its effects on independence and objectiv-
ity and yields somewhat mixed results. The same Messier
et al. (2011) paper discussed earlier reports no difference
in how external auditors perceive the competence of
non-rotational versus rotational internal auditors.
However, Ege (2015) uses archival data from the IIA and
?nds that measures of internal auditor competence (e.g.,
internal audit certi?cations and experience) are negatively
correlated with systematic rotation. Thus, it is reasonable
to conclude that the internal audit competence of a rota-
tional IAF will be similar or lower (but not higher) than
that of an IAF that does not use systematic rotation.
Taken together, previous literature suggests that using
systematic rotation is likely to be associated with lower
objectivity, and possibly lower competence among internal
auditors. Therefore, when considering the overall relation-
ship between systematic rotation and ?nancial reporting
quality, we predict that it will be associated with weaker
?nancial reporting quality than non-rotational internal
audit departments.
12
Stated formally:
H1. Systematic rotation lowers ?nancial reporting quality.
We next describe our interview process that led us to
further develop our framework.
Interview method
We interviewed heads of internal audit (i.e., CAEs) from
11 companies of varying sizes and industries and two audit
committee chairpersons who (combined) have worked
with 12 unique companies.
13
Table 1 provides demographic
information for our interviewees. Our heads of internal audit
vary in direct experiences with systematic rotation. Eight of
eleven companies use formal rotation programs, one uses
informal rotation, and two do not use rotation. However,
all of our interviewees indicated they had considered and
discussed this practice within their organizations.
Similarly, both audit committee chairmen sat on boards of
companies that did and did not use rotational models, and
both were knowledgeable about the practice.
Our goal in obtaining this varied sample was to learn
both positive and negative perspectives about systematic
rotation, especially aspects of the practice that may in?u-
ence the objectivity and competence of the IAF and, as a
result, ?nancial reporting quality. We developed a
semi-structured interview protocol (see Appendix A) with
open-ended questions (Lillis & Mundy, 2005; Yin,
2009).
14
Interviews began with questions about the
9
One notable difference between these models is that rotational models
that hire new auditors from outside the company are less likely to gain
organizational knowledge and expertise, which is a potential bene?t when
existing operational employees rotate through the IAF. This bene?t is
discussed more thoroughly in a later subsection.
10
For additional discussion of how rotational internal auditors may be
consciously or unconsciously biased, see Rose et al. (2013) and Koonce
(2013).
11
Hoos et al. (2014) show that rotational internal auditors are more likely
than non-rotational internal auditors to make recommendations that
management would prefer. Similarly, Rose et al. (2013) ?nd that rotational
auditors are more likely than non-rotational auditors to agree with
management’s aggressive accounting policies.
12
There is an additional reason we may not observe the relation
hypothesized in H1. The results of Messier et al. (2011) suggest that
external auditors are concerned about the potential lack of objectivity in
rotational IAFs; therefore, they price external audit services higher for these
?rms. If external auditors do more work to compensate for the lower
objectivity of the IAF, rotation will have no effect on ?nancial reporting
quality.
13
The audit committee chairmen served on the boards for multiple
companies, so we do not include them in cited statistics but rather discuss
their responses in general when they provide pertinent additional details.
14
Semi-structured questions allow for consistency, and thus higher
internal validity, while not restricting our ability to uncover new ideas
and concepts.

background of the organization, the head of internal audit
(or audit committee member), and the IAF. Interviews pro-
gressed to discuss speci?c experiences with systematic rota-
tion as well as the bene?ts and drawbacks of this practice for
internal auditors’ objectivity and competence. We concluded
the interviews by asking for descriptions of practices (i.e.,
compensating controls) used to ensure that the systematic
rotation was successful. Interviews lasted an average of
46 min. In Table 2 we report the risks, bene?ts, and compen-
sating control identi?ed by CAE interviewees and the num-
ber of individuals who speci?cally mentioned each.
To identify interviewees, we contacted the IIA who
reached out to potential interviewees on our behalf. Six
of eleven (55%) interviewees are from Fortune 500 compa-
nies. Internal audit department size ranges from 3 to 97
employees, and interviewees’ experience in their current
position ranges from 1 to 25 years. We identi?ed audit
committee member interviewees through accounting pro-
fessors from two universities. The audit committee mem-
bers represent 12 unique companies (9 public and 3
private), all with revenues over $1 billion in 2013.
One author conducted telephone interviews with all
heads of internal audit. Two authors conducted audit com-
mittee chairmen interviews in person. In general, we asked
questions in the order shown in the interview protocol;
however, we allowed interviewees to elaborate and move
to relevant or related topics naturally. We asked clarifying
questions as needed.
All interviews were recorded and transcribed, and later
coded independently by one author and one research
Fig. 1. Initial framework of the effects of systematic rotation on ?nancial reporting quality. This ?gure displays the initial framework we develop based on
prior literature and our interviews. The relationships that we test in this paper are shown with a solid line. Because we use archival analysis using data from
the IIA GAIN database, we do not directly test (or hypothesize) the effect of systematic rotation on internal auditor objectivity or independence. However,
we recognize that these are the underlying mechanisms through which systematically rotating internal auditors into management positions in?uences
?nancial reporting quality (shown with dashed lines). We also show several other compensating controls, described by interviewees, which we cannot test
with existing data, but should be explored in future research.

assistant. To code the interviews, one author reviewed
each transcript and identi?ed speci?c passages in which
an interviewee mentioned a risk or bene?t of systematic
rotation or a compensating control. The author then cate-
gorized each passage as a risk, bene?t, or control. The
research assistant then independently reviewed the inter-
views, identi?ed passages, and assigned each to one of
the same categories (i.e., risk, bene?t, or control). Any pas-
sages that the second coder could not categorize within the
initial set of choices were temporarily coded as other. The
coders identi?ed 133 passages related to risk (35), bene?ts
(54), and compensating controls (44). Inter-rater agree-
ment after the ?rst pass was 94%. The coders examined
and discussed any discrepancies until agreement was
reached.
Re?ning our initial framework for the effects of
systematic rotation on ?nancial reporting quality
In this section, we report insights fromour interviews. In
general, the interviewees’ comments support our predic-
tion in H1 that systematic rotation tends to cause lower
?nancial reporting quality, at least in absence of compen-
sating controls. In particular, our interviewees discussed
how systematic rotation lowers internal auditor objectivity
and competence—and is therefore likely to impair the orga-
nization’s ?nancial reporting quality (if left unchecked).
Additionally, interviewees indicate it is important to
expand our framework to consider compensating controls
that are likely to moderate these negative relationships.
Consistent with Taylor et al.’s (2003) conjecture that other
types of quality controls (e.g., training, reviews) may com-
pensate for a lack of external auditor independence, our
interviewees suggest that the following control mecha-
nisms can mitigate the adverse effects of systematic rota-
tion: (1) consistent and continuous IA supervision, (2)
audit committee’s oversight of the IAF, and (3) manage-
ment’s oversight of and direction for the IAF. Our intervie-
wees described these factors as a key compensating
control that mitigates the risk of diminished objectivity
and/or competence in internal auditors due to systematic
rotation. We extend prior literature by including these
controls in our initial framework (see Fig. 1).
Objectivity and competence
Many of the internal auditors we interviewed agreed to
some extent that systematic rotation can impair objectiv-
ity, competence or both. Eight of the eleven (73%) CAEs
acknowledged that internal auditor objectivity could be
impaired by systematic rotation. For example, CAE9
remarked,
‘‘That is a clear risk if they come in with the wrong mind
set [that] I’m just going to make friends and not call
things out in order to get a job in another area. . .’’
Similarly, CAE5 explained,
‘‘For instance, you do an audit in an area, and somebody
pulls a punch on a ?nding and doesn’t report the ?nding
because ‘gee, you know, I talked to so and so, and
they’re going to offer me this job when I get done with
this audit....’ So you have that risk.’’
Furthermore, CAE3 stated,
‘‘There is always [an objectivity] risk. If you’ve kind of
got your eye on sort of a sweet job out there that you’d
like to get, it comes into question of how likely is it that
you’re going to really raise a serious audit ?nding if you
know it’s going to be. . .a hard sell. I think that is a risk’’
With respect to competence, 8 of 11 (73%) interviewees
acknowledged that when internal auditors rotate out of the
IAF and into the organization, there is the potential for a
loss of internal audit expertise. For example, CAE10
described concerns about IAFs that rotate all internal audit
positions (i.e., no core group of ‘‘career’’ auditors is
retained):
‘‘I would argue if . . .[we’re] turning over my entire
internal audit group every two years. . .If I’m a board
member, an audit committee member, I would look
back and say, ‘How can you be giving me quality assess-
ments and quality audit work if everybody in your staff

or less?’’’
Similarly CAE7 said:
‘‘If you had an audit team that was full of . . . rotational
type people, you probably wouldn’t build up that sort of
expertise and knowledge. . . I could see a risk of a pure
rotational type function. You would just lose a lot of
corporate knowledge, and [that is a] key thing I would
think about.’’
However, several CAEs (6 out of 11) also described an
increase in organizational expertise gained from systematic
rotation—a potential bene?t not considered in prior aca-
demic research. Organizational expertise relates to knowl-
edge about the speci?c operations and procedures that
compose the core processes of the business. For example,
if an individual from manufacturing spends a two-year
rotation in internal audit as a stepping stone to a manage-
ment position, (s)he will bring speci?c knowledge about
manufacturing processes, risks, and controls into the inter-
nal audit function that may be dif?cult to gain simply by
auditing that process. In fact, many of our interviewees
believed the gain in organizational expertise could out-
weigh the loss of audit expertise. For example, CAE4 said,
‘‘Whenyoutalkabout competency, if you’re talking about
competency of the department, if we didn’t have rota-
tional [auditors], there would be more people involved
in internal auditing, and probably more sophisticated
internal auditing; but as far as expertise, havingrotational
[auditors] enlightens people and provides more wisdom
to them from the competencies that they’re bringing in,
so it enhances the department totally.’’
Also related to competence, Burton et al. (2015) ?nd
that more accounting students are willing to apply for an
internal auditing position if it will include systematic rota-
tion. This suggests that rotational IAFs will have a deeper
pool of candidates fromwhich to hire better quality profes-
sionals. Many of our interviewees echoed this sentiment.
In particular, 6 of the 11 (55%) CAE interviewees speci?-
cally mentioned that systematic rotation helps them
recruit and retain quality internal auditors. For example,
as CAE6 described,
‘‘It’s a great way to hire great people, and high-potential
people. . .If you’re just hiring internal auditors who are
quali?ed for the position to be internal auditors, you
probably aren’t going to get many of the best. So it puts
you in the market.’’

44 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Similarly, CAE5 explained,
‘‘[The] rotational program is good from the depart-
ment standpoint, because you’re going to have highly
motivated people. You’re going to have people who
seek career opportunities. You’re going to have people
who really are going to go in there and want to do
their best job because that’s how they’re going to
get the, you know, attention of people in the company
to want to hire them into their organizations,
their departments. So you don’t have to motivate
people.’’
Both audit committee chairmen echoed the belief that
using a systematic rotational staf?ng model attracts more
and better people.
In summary, although prior academic research pro-
vides relatively little evidence about the effect on compe-
tence of systematic rotation, our interviews suggest this
can have both positive and negative effects on IAF compe-
tence. Interviewees suggest that systematic rotation could
increase internal auditors’ competence by attracting more
and better people, and the IAF can bene?t from the oper-
ational expertise of operational personnel rotating
through the department. On the other hand, a high rate
of turnover within the internal audit department can also
lead to a loss of technical audit skills and audit expertise.
On balance, however, the loss of internal audit compe-
tence has the potential to hamper ?nancial reporting
quality. Thus, taken together, our interviewees provided
insights suggesting that systematic rotation poses risks
of impaired objectivity and competence consistent with
our prediction in H1.
Compensating controls
Our interviews revealed several critical compensating
controls companies can use to mitigate the impairment
of objectivity and (possibly) competence associated with
systematic rotation. The compensating controls described
by the interviewees provide various forms of oversight
over the IAF which can improve the IAF’s willingness
and capacity to prevent and/or detect low quality ?nan-
cial reporting. We conclude that the CAEs believe these
controls reduce the risk of impaired objectivity and com-
petence suf?ciently that the bene?ts of using the sys-
tematic rotational models exceed the risks. This is
consistent with Goodwin and Yeo’s (2001) ?nding that
nearly half of surveyed internal auditors disagreed that
the systematic rotation of internal auditors could impair
their work.
Although Taylor et al. (2003) conjecture that there may
be compensating controls that moderate the relationships
explored in their external auditor reliability model, with
the exception of a few studies that consider the effects of
audit committee activities, prior research has not
addressed the important compensating controls our inter-
viewees identi?ed. Based on our interviews, we include the
following compensating controls in our initial framework
as potential moderating variables and test their effects
with our archival data: (1) consistency and continuity of
IA supervision, (2) audit committee oversight, and (3)
management oversight and direction.
15
Consistency of IA supervision
Seven of the eleven (64%) CAEs and both audit commit-
tee chairmen described the importance of maintaining
some consistency in the higher levels of the IAF to reduce
the risk of diminished independence or competence result-
ing from systematic rotation. Most felt it was important to
have some career positions within the IAF (i.e., auditors
who did not rotate). For example, CAE3’s organization only
rotates internal auditors below the senior level:
‘‘One of the reasons that I set the program the way I did,
so that senior auditors and above no longer have to
rotate, is to try to maintain that continuity within the
department. . .there is that [competency] risk, and one
of the risks that I have right now is with such a small
department, if I do lose my senior, for example, then
that becomes a huge loss of support in that consistency
[and] de?nitely expertise.’’
Our interviewees described several ways that maintain-
ing some consistency in the department, especially at the
higher levels, helps to reduce objectivity and competence
concerns: higher level auditors reviewing others’ work
(45%), training and mentoring rotating staff and seniors
(45%), and facilitating discussions to ensure there are no
objectivity concerns (9%).
16
For example, CAE3 described
the importance of suf?cient supervision to reduce the
threats to objectivity:
‘‘[The] biggest way to mitigate that [objectivity] risk is
to really make sure that the folks that are not in line
of that succession, so a senior or above, [are] deeply
enough involved in the audit to where any
issue. . .would require collusion in order to bury it.’’
CAE9 also described the importance of mitigating con-
trols such as supervisory review, monitoring, and targeted
conversations:
‘‘It’s about conversations with the person, making sure
how they think, kind of what they’re looking at, how
they’re perceiving different risks that they’re seeing
15
Our interviewees identi?ed several other important compensating
controls that we do not currently test in this initial framework. These
include (1) prohibiting internal auditors from auditing departments for
which they have worked for at least 1 year (55%), (2) careful hiring
practices within internal audit (45%), (3) supervisory review of audit work
(45%), (4) training and mentoring of internal auditors (45%), and (5)
requiring a con?ict of interest statement (18%). We do not test these
additional compensating controls within this initial framework due to data
limitations; however, future research should consider their effects as
mitigating controls to reduce the potential risks associated with rotating
internal auditors into operational management positions.
16
These arguments are somewhat akin to the ?ndings on the effects of
external audit partner (and ?rm) rotation on audit quality, which describe
reduced audit quality after a rotation presumably due to the new auditor’s
lack of client-speci?c knowledge (e.g., Chi, Huang, Liao, & Xie, 2009).
Although regulatory bodies suggest that auditor rotation will improve audit
quality by allowing for a fresh set of eyes to review the ?nancials, this
comes at the loss of experience and knowledge which might can, at least
initially, outweigh the bene?t.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 45
out there, and then what actions they’re taking to fol-
low up on them to make sure that they’re digging all
the way down to get to the root cause.’’
With respect to the consistency and continuity of
supervision within the IAF, one of the critical decisions that
companies must make is whether to rotate the CAE posi-
tion speci?cally. Fifty-?ve percent of our interviewees
described concerns that there are increased risks to IAF
objectivity and competence when the CAE role is rotated.
Interviewees suggested that by rotating this position the
IAF not only loses valuable supervisory skills and internal
audit expertise, but the position is often ?lled by someone
with less (or no) internal audit experience. CAE3 described
the trend of rotating the CAE position as follows,
‘‘For me, it’s kind of a disturbing trend. I ?nd it problem-
atic, and I know why [management is] doing it. [They
want to] increase that ‘audit knows the business’ ele-
ment. . .but I don’t think they realize exactly how much
of a hole that person is in, starting from zero to try and
lead an audit function. There’s such a learning curve,
and it’s not something that they’re going to pick up in
six months or a year. . . I think it’s a big disconnect on
the part of management as far as understanding how
internal audit works.’’
With respect to objectivity, some interviewees
expressed concerns that the CAE would focus primarily
on pleasing executive management. CAE5 described the
risk as follows:
‘‘You know, the mindset of a career professional chief
audit executive, in my opinion, is different than the
mindset of a rotational chief audit executive. My job
[as CAE is] to make sure I did a dog-gone good job as
the chief auditor and make sure that the audit commit-
tee’s rear end was protected. Rotational chief auditors
may not have that as their goal and may have the goal
of, I want to become the CFO someday or the CEO, so I
want to keep the people and executive management
happy, and just sort of hope to keep the audit commit-
tee happy.’’
CAE5 continued to explain how a rotating CAE may face
challenges when reporting identi?ed weaknesses to execu-
tive management,
‘‘As a career auditor, I just know the challenges that a
person has when you’ve got to walk in and tell the
CFO or the CEO that something is going wrong in your
area and [they’re] not necessarily happy to hear it.
And so to me, it’s a lot easier when it’s like this is my
job, that’s the way I’m calling it, and I’ve got to tell
you this versus, gee, if I just sort of like kind of tell
you, and I don’t really tell the audit committee or any-
body else, and you’re still happy, we can go ?x the prob-
lem, and good, and everybody is going to be happy with
this, and that problem just goes away and gets ?xed. . .A
career auditor will know that I have a ?duciary respon-
sibility to let people know this thing is a problem, needs
to be addressed, and yeah, it’s probably going to get
?xed, but I’m going to tell the audit committee, because
they need to be aware of it.’’
CAE3 described a related but different risk to objectivity
when the CAE is a rotating position. In particular, he
described how it can affect the objectivity of the current
IAF staff because they could be uncomfortable auditing a
former supervisor:
‘‘When the chief audit executive is rotating as well, I
think that’s where you start to really run into some
impairments, because then you’ve got a really close
tie with. . .that individual who is now out in the busi-
ness. And so you take an audit staff, and they actually
end up in a position of auditing their former boss.’’
Finally, AC2 summarized these concerns when he
explained why none of the companies with which he was
involved rotated the CAE position:
‘‘[We] just felt that it was better to have stability at the
top, because we did feel that we wanted to have, if we
could, more rotation underneath. And having stability
at the top was a way of providing more continuity and
just felt that if the whole thing was turning over, that
was going to be just a little more dif?cult to manage.’’
In sum, we expect that maintaining consistency and
stability in the IAF can mitigate the risk of impaired IAF
objectivity and competence when internal auditors are
systematically rotated into management positions.
Formally, we hypothesize:
H2. Among companies using systematic rotation, limiting
it to internal audit staff only (not CAE) increases ?nancial
reporting quality.
Audit committee oversight
Audit committees are responsible for ?nancial report-
ing quality and for overseeing internal and external audit
processes; however, due to a variety of factors (e.g., organi-
zational complexity, internal auditor reporting lines), audit
committee effectiveness can vary widely in this regard
(Beasley, Carcello, Hermanson, & Neal, 2009). IIA
Standards require that the CAE report to the audit commit-
tee (or an equivalent) and recommends a dual reporting
relationship in which the CAE reports functionally to the
audit committee and administratively to senior manage-
ment (Alkafaji, Hussain, Khallaf, & Majdalawieh, 2010).
Prior literature shows that the audit committee is often
involved with hiring and ?ring the CAE and reviewing or
approving the internal audit budget. Further, in many
organizations the audit committee meets frequently and
privately with the CAE (Anderson, Christ, Johnstone, &
Rittenberg, 2011; Beasley et al., 2009). Beasley et al.
(2009) interview 42 audit committee members and pro-
vide rich descriptions of audit committee activities, includ-
ing internal audit oversight. Drawing from agency theory
(e.g., Jensing & Meckling, 1976) and institutional theory
(e.g., Cohen, Krishamoorthy, & Wright, 2007; Scott, 1987)
the authors consider whether audit committees’ practices
are more indicative of effective monitoring of manage-
ment, as predicted by agency theory or primarily serve cer-
emonial purposes, as predicted by institutional theory.
46 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Results of the interviews are mixed, suggesting that
although some audit committee members are committed
to effective monitoring, ceremonial activities commonly
occur in some organizations. To the extent that an audit
committee’s activities are primarily ceremonial, they will
not translate into an effective audit committee. Much like
audit committee performance, the internal audit function
likely varies widely (Beasley et al., 2009).
Prior accounting research suggests that audit commit-
tee oversight is an important factor that moderates the
proposed negative relation between the use of systematic
rotation and ?nancial reporting quality (Abbott, Parker, &
Peters, 2007, 2010; Agoglia, Doupnik, & Tsakumis, 2011;
Goodwin & Yeo, 2001). For example, Goodwin and Yeo
(2001) ?nd some evidence that systematic rotation is clus-
tered in ?rms with strong audit committees, which they
speculate, but do not test, could mitigate potential objec-
tivity concerns. Abbott et al. (2007, 2010) suggest that high
quality audit committees may be able to provide suf?cient
oversight when internal auditor independence is threat-
ened.
17
Rose et al. (2013) ?nd some evidence that audit
committees with more power over management’s promo-
tion opportunities are associated with less objective (rotat-
ing) internal auditors.
18
Overall, prior research suggests
that an effective audit committee may be able to reduce
the negative effect on ?nancial reporting quality associated
with systematic rotation that we hypothesize in H1.
Interviewees agree with the prior research. In particu-
lar, 6 out of 11 interviewees (55%) discussed the impor-
tance of audit committee oversight and direction. For
example, CAE1, CAE5, and CAE11 (respectively) describe
the monitoring role of the audit committee over the IAF:
‘‘We do an annual risk assessment. The audit committee
is part of that risk assessment. They approve my audit
plan. Every year they approve any changes I make to
the audit plan. To the extent there are hot topics,
emerging issues, things that are on their mind, they’re
certainly going to bring those up, and we’ll incorporate
them as appropriate.’’
‘‘Well, we certainly spent time with our audit commit-
tee to talk to them about, for instance, when we devel-
oped our audit plan and presented our audit plan. We
went through with them the approach we went and
identi?ed for our risk assessment, so that they would
understand why there were certain audits that were
in the plan.’’
‘‘The audit committee is heavily involved, quite frankly,
so they see I work for them indirectly, right? They
appoint me. They could get rid of me, they do my bud-
get approval each year, my rating, my top, everything
associated with the program, they’re involved with.’’
CAE2 also describes how his/her audit committee is
aware of IA staff rotations:
‘‘I meet quarterlywith[the audit committee] andwe pro-
vide to them on that quarterly basis an update of where
we are on the plan, how many hours, for example, etc. I
provide them updates real time on staff changes, so if I
have someone leaving or moving into the organization,
they know about it within a quarter, generally sooner.’’
Relatedly, CAE4 indicated that his/her audit committee
monitors the success of the rotational program based on a
pre-established metric (e.g., rotate two internal auditors
into the business per year) in the same manner that they
evaluate the IAFs performance relative to other metrics.
Audit committees can improve ?nancial reporting qual-
ity in a variety of ways such as asking external auditors to
do more work, questioning management to a greater
degree (Gendron & Bedard, 2006), shifting internal audi-
tors’ work to focus on ?nancial audits, increasing informal
meetings and communication with the IAF (Zaman &
Sarens, 2013), or other similar activities. Our interview
with AC1 supported this notion:
‘‘[The] compensating control is that as an audit commit-
tee member and as the [audit committee] director, we
get all the audit reports. We not only get their summary,
but we get the entire report that’s written up, so after a
while, you get so you can sort of judge quality.’’
The interviews and prior research lead to our third
hypothesis.
H3. Among companies using systematic rotation, those
having relatively strong audit committee oversight have
higher ?nancial reporting quality.
Management oversight and direction
Prior literature (e.g., Anderson & Dahle, 2009) and our
interviews revealed that different IAFs focus on different
types of audit work (e.g., operational audits, ?nancial
audits, external audit support, and management’s
requests) and that management can signi?cantly affect
the type of work performed by and the results reported
by the IAF. In particular, 4 of 11 (36%) of our interviewees
described management’s involvement and direction in the
areas of audit focus and the scoping of particular audits.
For example, CAE9 describes how management can direct
and assist in audit work:
‘‘They have a lot of input. They provide color around
areas. They provide suggestions on areas to be audited.
[But] they don’t stop us from auditing areas. We have
free access to any information that we need to audit
17
Abbott et al. (2007) ?nd that in the pre-SOX era, ?rms with strong audit
committees are less likely to outsource routine internal audit activities to
their external audit ?rm. They interpret these results to mean that high
quality audit committees are more effective at managing independence
issues within the IAF. Abbott et al. (2010) ?nd that when audit committees
have greater oversight of the IAF, they are better able to steer internal audit
activities toward performing internal control work than when management
has greater internal audit oversight.
18
Rose et al. (2013) focus on a narrow issue related to the power of the
board of directors to appoint members of management, thereby reducing
senior management’s ability to promote internal auditors into management
functions. While their study shows that empowering the board with this
responsibility further reduces IAF objectivity, this result is not necessarily
generalizable to the broader construct of audit committee effectiveness. We
extend Rose et al. (2013) by examining the broader issue of how overall
audit committee oversight interacts with the systematic rotation of internal
auditors on ?rm-level ?nancial reporting metrics.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 47
an area. . .. they’re real good about, you know, saying
hey, I’d really like you to look into this area.’’
CAE11 similarly reports management’s expectations
play a large role:
‘‘It’s changed over the years, so when I ?rst became the
Chief Audit Executive, I reported to our CFO. . .[then] I
got moved to our [chief legal of?cer]. . .and then move-
d. . .to our CEO, so as those transitions have occurred, so
has really my drive and push to do different things. So
of course when this was a CFO function with my prede-
cessor, the group talked about ?nance stuff. . .’’
The interviews suggest that management’s interests
affect the work performed by the IAF—especially if the
IAF uses a rotational staf?ng model. Thus, if management
expects internal audit to focus on ?nancial reporting qual-
ity, this will operate as a compensating control in that the
internal auditors will be more likely to do so, which we
expect will help ensure higher ?nancial reporting quality.
This leads to our ?nal hypothesis:
H4. Among companies using systematic rotation, those
that more heavily focus internal auditors on ?nancial
matters have higher ?nancial reporting quality.
Archival data and model speci?cation
Sample and data
We use several datasets to test our hypotheses. We
obtain data about IAFs from the GAIN database, gathered
by the IIA. We use data from the Compustat, CRSP, Audit
Analytics, and RiskMetrics databases to obtain the remain-
ing variables. Similar to Messier et al. (2011), we lose 148
?rm-years because of inconclusive data concerning the use
of systematic rotation.
19
Our data requirements result in
353 ?rm-year observations, which correspond to 157 com-
panies in 38 different two-digit SIC code industries from
the years 2000 to 2005.
The IIA GAIN database compiles survey responses from
chief audit executives associated with IIA member organi-
zations, and thus includes a wide range of institutions (e.g.,
publicly-traded companies, private companies, educational
institutions, subsidiaries and divisions within companies,
and governmental institutions). The survey covers various
aspects of internal audit practice and provides benchmark-
ing data for participating companies. The survey changes
slightly from year to year, but none of the questions
included in this study changed over our time period.
20
The IIA does not reveal participating companies’ identi-
ties. Thus, we match several self-reported ?elds in the
survey with data items in Compustat to include appropri-
ate control variables in our study. Speci?cally, following
Prawitt et al. (2009), we match on self-reported total
assets, total revenues, and operating industry to identify
companies. We include all companies for which we can
match identically all three metrics in a particular year
and then use the unique identi?er in the IIA data to iden-
tify subsequent or previous ?rm year responses.
21
We measure ?nancial reporting quality using
Accounting Risk, a proprietary measure developed by
Audit Integrity. Audit Integrity uses publiclyavailable ?nan-
cial data to estimate the likelihood that reported ?nancial
information includes elements that are intentionally mis-
leading or fraudulent (Audit Integrity, 2005). Accounting
Risk is the output of a proprietary model that evaluates pub-
lic companies’ ?nancial reports and independently assesses
the risk of misreporting by identifying suspicious patterns
in accounting. Thus, Accounting Risk is an ex ante estimate
of the risk that companies are engaging in inappropriate
or aggressive ?nancial reporting.
22,23
The Accounting Risk
measure, scaled from 0 to 100, is decreasing in risk (a value
of 100 suggests very low risk). For ease of interpretation
and to be consistent with prior research (Price et al., 2011),
we invert the scale so it is increasing in risk (a value of 100
suggests very high risk). A positive relation between system-
atic rotation and Accounting Risk (H1) suggests that system-
atically rotating internal auditors into management positions
is associated with lower ?nancial reporting quality.
Price et al. (2011) provide evidence supporting the con-
struct validity of the Accounting Risk measure. Speci?cally,
they ?nd that the measure is as good as or superior to a
variety of academic risk measures for predicting SEC
enforcement actions, irregular restatements (Hennes,
Leone, & Miller, 2008), and lawsuits related to accounting
malfeasance.
Addressing selection bias
Because organizations choose whether to use systematic
rotation, selection bias is a concern in our study.
Researchers have identi?ed several econometric techniques
for mitigating the effects of selection bias (see summaries in
Francis, Lennox, & Wang, 2010; Larcker & Rusticus, 2010;
and Tucker, 2010). We use a Heckman self-selection model
for several reasons: (1) selection bias due to unobservable
omitted variables is the chief concern in our setting; (2)
?rms’ choice to use rotational staf?ng models is binary;
(3) we identify an exogenous, independent variable in the
19
The IIA survey asks respondents if they systematically rotate staff and
the CAE position and gives them four options from which to choose. These
options include using staff and CAE positions as rotational, career,
rotational moving to career, and career moving to rotational. Consistent
with Messier et al. (2011), because it is not possible to discern the degree of
‘‘movement’’ for the latter two categories, we exclude these ?rm-years
from our study.
20
After 2005, the IIA no longer included the question on systematic
rotation as a staf?ng model.
21
Prawitt et al. (2009) report that this matching procedure correctly
identi?es ?rms in the IIA’s database.
22
Data relating to companies’ IAFs are not directly used in the calculation
of Audit Integrity’s risk measure. Ideally we would also examine ex post
measures of accounting risk (e.g., SEC enforcement actions, restatements,
etc.). However, similar to Prawitt et al. (2012), there is minimal intersection
of these type events with our data; therefore, we are unable to perform an
ex post analysis.
23
Accounting Risk is calculated based on the following inputs: (1)
expense recognition, (2) revenue recognition, (3) high risk events, and (4)
asset and liability valuation. Audit Integrity measures each component
using the following metrics: (i) the percentage change from the prior year,
(ii) number of standard deviations from the industry average, and (iii)
volatility over two years (Price et al., 2011).
48 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
?rst stage model that we appropriately exclude from the
independent variables in the second stage model; and (4)
from a practical perspective, the relatively small sample of
companies with IAF data makes it dif?cult to identify good
matches using propensity score matching.

(See Appendix B for variable de?nitions.)
In Eq. (1), the dependent variable is the dichotomous
choice variable, Rotate, which equals 1 if the ?rm uses sys-
tematic rotation and 0 otherwise. The Heckman selection
model requires us to identify an exogenous independent
variable in the ?rst stage model that we can appropriately
exclude from the second stage model (Francis et al., 2010).
We include MeanIndRotate, which represents the industry
average use of rotational staf?ng models (excluding the
company itself). Companies commonly benchmark their
IAF practices basedon industry peers; thus, if industry peers
systematically rotate internal auditors into management
positions, we posit that a company will be more likely to
do so as well. Thus, we expect a positive coef?cient on
MeanIndRotate. It is appropriate to exclude MeanIndRotate
from the second stage models explaining Accounting Risk
because there is no reason to expect that the industry
benchmark for using a rotational staf?ng model will affect
an individual company’s accounting risk.
Our prediction model also includes a number of addi-
tional variables. First, we control for two other internal
audit characteristics that might be associated with the
choice to use systematic rotation by including
IACompetence and Outsource. We include IACompetence
because Messier et al. (2011) provide univariate evidence
that systematic rotation is negatively associated with inter-
nal audit quality. We also include a dichotomous measure
to capture whether companies outsource work of the IAF
to a third party (Outsource) because it is unclear whether
?rms that use systematic rotation are likely to outsource
IA positions. Outsource is equal to 1 if a company outsources
any or all of its IAF to a third party, and 0 otherwise.
24
To
control for the effect of various corporate governance mech-
anisms, we include the effectiveness of the audit committee
(AuditCommittee), two measures of external auditor quality
(AuditSpecialist and AuditFee), and management’s power over
the board of directors (Gindex) (Gompers, Ishii, & Metrick,
2003). We expect higher quality corporate governance will
be negatively associated with the systematic rotation.
We control for size (Assets), leverage (Leverage), com-
plexity (Complexity), market-to-book (MB), age (Age), and
an indicator for companies listed on the New York Stock
Exchange (NYSE), as each of these ?rmcharacteristics could
affect the decision to use systematic rotation (Messier et al.,
2011). We also include six industry dummy variables rep-
resenting one-digit SIC code industries. We control for year
effects by including indicator variables for each ?scal year.

(See Appendix B for variable descriptions.)
AR is the accounting risk measure described previously.
Rotate is a dichotomous variable measuring whether a
company uses systematic rotation. A positive coef?cient
on this variable would indicate that, consistent with
Hypothesis 1, companies that use systematic rotation have
higher accounting risk than companies that do not.
Audit committees are monitors of the ?nancial reporting
process. Therefore, we control for the CAE reporting to the
audit committee (CAEAC), effectiveness of the audit com-
mittee (AuditCommittee), and audit committee diligence
(MeetOften). We expect a negative coef?cient for CAEAC,
AuditCommittee, and MeetOften. To control for the expertise
of the IAF, we include IACompetence and QAR which mea-
sure things such as certi?cations, experience, and training
(see Appendix B for full discussion) and whether the IAF
has had a recent quality annual review. We also control
for turnover within the IAF (Turnover) as turnover may
decrease the monitoring ability of the IAF, thus increasing
accounting risk. Furthermore, IAFs that use systematic rota-
tion are likely to have higher turnover (Messier et al., 2011),
and we want to evaluate whether systematic rotation is
what is associated with accounting risk while holding con-
stant the effects of turnover. Prawitt et al. (2012) also
demonstrate that outsourcing work of the IAF can affect
24
In untabulated analyses, we include measures of whether the out-
sourced service provider was the external auditor (Prawitt et al., 2012). Our
inferences are qualitatively similar to those reported when we include
these alternative measures and therefore, for parsimony, we report our
results with the single outsourcing measure. For purposes of this paper, we
de?ne qualitatively similar to mean the results are of the same statistical
signi?cance (statistically signi?cant p-value < 0.05, marginally signi?cant
p-value < 0.10) and of the same sign. We also note that in our sample, the
average amount of the IAF that is outsourced to a third party is 9.4%
(median of 3.0%). There is one ?rm-year observation that outsourced 100%
of the work. At the 95th percentile, 40% of the work is outsourced. Since
only a small part of the IAF is outsourced, there are many positions that are
still available for systematic rotation.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 49
accounting risk, thus we include a measure of outsourcing
in our model (Outsource).
In addition, we expect a negative association between
accounting risk and external auditor quality
(AuditSpecialist), but a positive association between
accounting risk and external audit fees (AuditFee)
(Charles, Glover, & Sharp, 2010). For Gindex, we expect a
positive relation with accounting risk as higher values of
Gindex suggest greater management power and thus
weaker corporate governance.
The other control variables are relatively standard in
the literature, so we omit their detailed descriptions (for
detailed discussion see Beneish, 1997; Dechow, Sloan, &
Sweeney, 1996; Jones, Krishnan, & Melendrez, 2008;
Matsumoto, 2002; Menon & Williams, 2004; Prawitt
et al., 2012; Richardson, Tuna, & Wu, 2002; Romanus,
Maher, & Fleming, 2008). Lambda is the inverse Mills’ ratio
computed from Eq. (1), which we include in order to con-
trol for the effects of self-selection bias due to unobserv-
able factors. As a reminder, MeanIndRotate, is the
independent variable from Eq. (1) that we exclude from
Eq. (2).
25
We do not tabulate coef?cient estimates for the
industry and year indicators as we have no ex ante predic-
tion about whether the risk of fraudulent or inappropriate
accounting transactions differs by industry or over time.
Finally, we cluster standard errors by company.
26
Testing effects of compensating controls
To test Hypothesis 2, we rerun Eq. (2) splitting Rotate
into three variables: RotateCAE is a dichotomous variable
indicating whether the chief audit executive position is
systematically rotated, RotateEmp is a dichotomous vari-
able indicating whether only staff positions are systemati-
cally rotated, and RotateBoth is a dichotomous variable
indicating whether both staff positions and the CAE posi-
tion are systematically rotated. H2 posits that the coef?-
cient on RotateCAE will be greater than the coef?cient on
RotateEmp, which we test using an f-test.
To test H3 and H4 we estimate the following cross sec-
tional regression model:

Eq. (3) includes one new variable and several interac-
tion terms. The new variable, MGMTFocus, is a dichoto-
mous variable taking the value of one if management
expects internal audit to focus on both risk assessments
and internal consulting on ?nancial matters (versus a focus
on compliance (laws and regulations) or internal consult-
ing on operational matters).
To test H3, we interact Rotate with three separate mea-
sures capturing audit committee oversight. These three
audit committee variables capture both audit committee
effectiveness characteristics (AuditCommittee) and activi-
ties (CAEAC and MeetOften). We expect ?rms with strong
audit committee oversight to have effective audit commit-
tee characteristics, to direct the CAE to report to the audit
committee, and to meet more often with the CAE. A nega-
tive coef?cient on the interaction terms Rotate ? CAEAC;
Rotate ? AuditCommittee; and Rotate ? MeetOften would
support H3. The relationship between the IAF and the audit
committee is likely multi-faceted, so we cannot ex ante
predict which variable is the most important factor
impacting the relation or whether all should be signi?cant.
To test H4, we interact MGMTFocus and Rotate. A nega-
tive coef?cient on this interaction would suggest that, con-
sistent with H4, management’s expectations that internal
auditors focus on ?nancial work improves ?nancial report-
ing quality for ?rms that use systematic rotation.
Results
Descriptive statistics and univariate comparisons
Table 3, Panel A presents descriptive statistics. For brev-
ity, we highlight select variables here. Overall, 82% of sam-
ple ?rm-years report using systematic rotation. Companies
that use this practice are most likely to systematically
rotate staff positions (RotateEmp = 0.42). In addition, the
sample consists of large companies that are not highly
leveraged or overly complex. Finally, our sample ?rms
appear to have reasonably competent IAFs as the
IACompetence exhibits only a one point difference between
the 25th and 75th percentiles. In Table 3, Panel B we pro-
vide a correlation matrix.
Table 4 presents the results of the ?rst stage model that
explains the choice to systematically rotate internal audi-
tors. As expected, the use of systematic rotation by a com-
pany’s industry peers is positively related to a company’s
decision to use systematic rotation (i.e., MeanIndRotate is
positive and p-value < 0.01). In addition, the more compe-
tent the IAF, the less likely it will be to use systematic rota-
tion (p-value < 0.01). Outsourcing some of the IAF is
positively associated with systematic rotation
(p-values < 0.05).
27
Consistent with Messier et al. (2011),
25
Our inferences are robust if we include any or all of the additional
control variables from Eq. (2) in Eq. (1) (e.g., return, loss, etc.).
26
An alternative to including year ?xed effects is to cluster our standard
errors by both ?rm and year. However, given the small number of years in
our sample period, year ?xed effects are preferable (Peterson, 2009).
27
We provide two possible explanations for the positive relation between
outsourcing and systematic rotation. First, a company that uses systematic
rotation may choose to use internal auditors in tasks that develop their
management skills, while purchasing outsourced services in areas that are
not as important for management. Second, the head of internal audit,
perhaps in conjunction with the audit committee, is aware that IAFs that
use systematic rotation might be missing some internal audit skill sets;
thus, they may purchase specialized skill sets using outsourcing arrange-
ments. Regardless, our statistical analyses control for these possibilities;
thus, our results are not confounded by the association between out-
sourcing and the use of systematic rotation. We encourage future research
to examine this issue more closely.

companies that use systematic rotation have higher external
audit fees (p-value < 0.05). From this model, we compute the
inverse Mills’ ratio and use it to control for selection bias in
the remaining models.
28
Hypothesis testing
H1 predicts that companies that use systematic rotation
will have lower ?nancial reporting quality, which we oper-
ationalize as higher accounting risk. The results, presented
in Table 5, Panel A show that the coef?cient estimate for
Rotate is positive and statistically signi?cant
(p-value < 0.01). This result supports H1 and suggests that
companies that systematically rotate their internal auditors
have greater accounting risk (i.e., lower ?nancial reporting
quality) than companies that do not use systematic rota-
tion. Of our two IAF expertise measures, we ?nd that QAR
is negative and statistically signi?cant (p-value < 0.05)
while IACompetence is not signi?cant (p-value > 0.10). Of
the other control variables, Turnover, Outsource,
AuditSpecialist, Assets, Complexity, Loss, and Return are statis-
tically signi?cant, all in the direction predicted
(p-values < 0.10). Our inferences about the association
between systematic rotation and accounting risk are unli-
kely to be affected by selection bias due to unobserved com-
pany characteristics because the model includes the inverse
mills ratio, Lambda, from the Rotation prediction model.
Panel B of Table 5 shows the results of tests of H2
which examine whether companies that systematically
rotate the chief audit executive position have higher
accounting risk than companies that only rotate staff
internal audit positions (H2). The test of RotateCAE =
RotateEmp shows that the coef?cient on RotateCAE is
higher than the coef?cient on RotateEmp (p-value < 0.05),
supporting H2. We also ?nd that systematically rotating
both the chief audit executive position and staff positions
is associated with higher accounting risk than using just
staff positions (p-value < 0.05). Thus, as our interview
data suggest, systematically rotating the head of internal
audit position is particularly troublesome in its effects
on ?nancial reporting quality. We also note that all three
of the Rotate variables are positive and statistically signif-
icant (p-values < 0.01); thus, using only rotating staff
positions is not a cure-all—it is still associated with higher
accounting risk.
In Table 6, we present our tests of H3 and H4. H3 posits
that a strong audit committee mitigates the negative
?nancial reporting effects of using systematic rotation.
The negative coef?cient on Rotate ? AuditCommittee
indicates that a more effective audit committee is associ-
ated with a reduction in the incremental accounting risk
from using systematic rotation (p-value < 0.05). Having
the head of internal audit report to the audit committee
and having more frequent meetings are directionally
consistent but not statistically signi?cant at traditional
levels (p-values = 0.109 and 0.120, respectively).
However, having a strong audit committee is not suf?cient
to completely mitigate the negative effect of using
systematic rotation because the sum of Rotate + Rotate ?
CAEAC + Rotate ? AuditCommittee + Rotate ? MeetOften = 0 is
still positive (p-value < 0.01).
In H4, we posit that if management asks internal
auditors to place greater focus on improving ?nancial
reporting, systematic rotation will be more likely to reduce
?nancial reporting risk. The results of our test support this
hypothesis in that the Rotate ? MGMTFocus interaction is
negative and moderately signi?cant (p-value < 0.10).
Again, management’s expectation that the IAF focus on
?nancial reporting is not suf?cient to completely
mitigate the negative effect of using systematic rotation,
because Rotate + Rotate ? MGMTFocus = 0 is still positive
(p-value < 0.01).
We examine whether the combination of a strong audit
committee and management focus on having internal audit
improve ?nancial reporting completely mitigates the nega-
tive effect of using systematic rotation by testing whether
the sum of Rotate + Rotate ? MGMTFocus + Rotate ?
CAEAC + Rotate ? AuditCommittee + Rotate ? MeetOften = 0.
This sum is not statistically different from zero
(p-value > 0.10) suggesting that the combination of both a
strong audit committee and management focus on ?nancial
reporting eliminates the negative ?nancial reporting effects
of using systematic rotation.

Audit committee effectiveness is not signi?cant in explaining the
choice to use systematic rotation. This result is somewhat surprising given
prior research showing that the audit committee appears to distinguish
between outsourcing arrangements that are more or less likely to produce
economic bonding (Abbott et al., 2007). However, our result is based on a
relatively small sample, and the audit committee does not always decide
whether to systematically rotate internal auditors (this decision can also be
made by the CEO, the CFO, or the CAE). Several of our interviewees
indicated that the decision to use a rotational staf?ng model for the IAF was
made by other individuals or groups within the organization. For example,
in some companies the decision is made by executive management (e.g.,
CFO), and often, it is driven by the CAE him/herself.
52 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
Taken together, the results suggest that systematically
rotating internal auditors into management positions can
impair the IAF’s effectiveness in monitoring the ?nancial
reporting process. One such negative consequence of using
systematic rotation is increased accounting risk as com-
pared to companies that do not use systematic rotation.
This means companies that use systematic rotation have
an increased likelihood of intentional misstatement and/or
fraud in their ?nancial statements. However, a strong audit
committee and management’s directive to the IAF to focus
on ?nancial reporting issues can serve as compensating
controls that can mitigate the extent to which systematic
rotation increases accounting risk.
Robustness tests
As two alternative tests of H1, we repeat the same anal-
ysis in Table 4, Panel A, using alternative dependent vari-
ables. Instead of Accounting Risk, we use Dechow, Ge,
Larson, and Sloan’s (2011) fraud risk score (F-score) and
an abnormal accruals measure based on Dechow, Sloan,
and Sweeney (1995). F-score was designed to identify the
same types of egregious accounting irregularities as Audit
Integrity’s Accounting Risk measure. Consistent with our
results, for both alternative dependent variables, we
observe a positive and signi?cant coef?cient
(p-value < 0.05) on Rotate. Thus, our results for H1 are
robust using alternative measures of the risk of ?nancial
misreporting.
We also retest H2 using the alternative dependent vari-
ables. Rotate CAE, Rotate Both, and Rotate Emp remain pos-
itively associated with accounting risk (p-values < 0.05),
but the differences between variables are no longer statis-
tically signi?cant. We also repeat our tests of H3 and H4,
using the alternative dependent variables. H3 is supported
when we use the F-score (p-value < 0.05) but is not statis-
tically signi?cant when we use the abnormal accrual mea-
sure (p-value = 0.145). Similarly, the results for H4 hold
with the F-score measure (p-value < 0.05), but not with
the abnormal accrual measure. Overall, the results are rea-
sonably robust to using noisier proxies for ?nancial report-
ing quality (Price et al., 2011).
A potential alternative explanation for H1 is that our
accounting risk measure is simply picking up the external

auditor’s pricing of reduced audit quality or the external
auditor’s reliance on the IAF (Hribar, Kravet, & Wilson,
2014; Messier et al., 2011). To control for this possibility,
we include as a control variable the unexpected audit fee
measure developed by Hribar et al. (2014). This measure
does not load signi?cantly in our tests, and our inferences
remain robust.
Conclusions
In this paper, we examine whether the practice of sys-
tematically rotating internal auditors into management
positions (i.e., systematic rotation) is associated with lower
?nancial reporting quality. We also investigate compensat-
ing controls, which we derive from interviewing practicing
heads of internal audit and audit committee members,
which can strengthen the IAF’s capacity and willingness
to detect and prevent low quality ?nancial reporting and
thereby mitigate this negative relation. Consistent with
our causal predictions, we ?nd that systematic rotation is
associated with lower ?nancial reporting quality, indicat-
ing that companies that employ this practice may be more
susceptible to misleading or fraudulent ?nancial reporting
than companies that do not use this practice. We also ?nd
that several key compensating controls that provide over-
sight to the IAF do moderate this negative effect. That is,
the negative relationship between using systematic rota-
tion and ?nancial reporting quality is reduced if the follow-
ing compensating controls, are used: (1) only staff internal
audit positions (not CAE) are rotated, (2) there is a more
effective audit committee, or (3) management asks inter-
nal audit to have a greater role in the ?nancial reporting
process. Further, using the compensating controls together
eliminates the negative association between systematic
rotation and impaired ?nancial reporting quality.
These results inform practitioners and scholars about
whether and how the IAF impacts organizations. The
IIA’s de?nition of internal auditing states that internal
auditors should be independent and ‘‘add value by
improving an organization’s operations, risk management,
control, and governance processes’’ (2011a). Our results
suggest that systematic rotation, without the implemen-
tation of appropriate compensating controls, may impair
the IAF’s ability to monitor ?nancial reporting quality.
Internal audit standard setters and practitioners, as well
as others interested in corporate governance, should ?nd
these results useful in helping to improve the IAFs ability
to ful?ll its charge.
Our results contribute to the existing literature on sys-
tematic rotation (i.e., research on using the IAF as a MTG)
in several important ways. First, ours is the ?rst study to
investigate the effect of this practice on ?nancial reporting
quality. While prior research has examined its effects on
objectivity (Rose et al., 2013) and perceived objectivity
(Messier et al., 2011), we use archival data to test and ?nd
that these effects extend beyond the internal auditor to the
impairment of ?nancial reporting quality. Second, we
advance the literature by examining several key compen-
sating controls that can improve the IAF’s willingness and
capacity to prevent and/or detect low quality ?nancial
reporting. When organizations implement these control
practices, which provide various forms of oversight to the
IAF, the negative effect of systematic rotation diminishes.
When the controls are used together, the negative effect
can be eliminated. Third, our interview data provides
insights into the practice of systematic rotation including
its bene?ts and challenges. Prior research has not consid-
ered the bene?ts of systematic rotation and further explo-
ration is warranted to better understand how it helps the
IAF add value to the organization.

The results of this study are subject to several limita-
tions that suggest avenues for future research. First, archi-
val research is limited in its ability to test causal relations.
The model we develop from interviewing practitioners
suggests factors that can affect the objectivity and compe-
tence of internal auditors. Researchers using experimental,
survey, case study, interview, and other methods may be
able to shed additional light on this model and our ?nd-
ings. For example, experiments can be used to more
directly test whether objectivity and competence mediate
the relation we observe between systematic rotation and
?nancial reporting quality.
29
Using complementary
research methods can triangulate research ?ndings and
improve our understanding of how the IAF affects ?nancial
reporting quality.
Second, we include in our initial model and test three
key compensating controls identi?ed by the CAEs we
interviewed. However, the CAEs also mentioned other
important compensating controls that we were not able
to test due to data limitations (e.g., hiring practices,
supervisory review practices). Future research should
explore whether and how these other controls may miti-
gate the risks of rotating internal auditors into opera-
tional management positions. For example, experimental
methods may be useful to determine whether different
methods of workpaper review can mitigate the risk of
impaired independence/objectivity.
Third, due to data availability constraints, our analysis
is limited to data collected between 2000 and 2005.
Although this was a tumultuous time for publicly traded
corporations, there is no reason to believe the events of
this time period would be correlated with the use of the
systematic rotation. In particular, the changes that
occurred during this period (e.g., the implementation of
SOX) would likely have affected companies that do and
do not rotate internal auditors in similar ways. We believe
examining practices associated with internal auditing and
how companies can improve their IAFs to ensure high
quality corporate governance is an important area for
future research.
Overall, this paper makes an important contribution to
research and practice by demonstrating that although sys-
tematic rotation of internal auditors into management
positions is negatively associated with ?nancial reporting
quality, the negative effects can be mitigated with
appropriate compensating controls. Most of the prior liter-
ature has identi?ed risks to internal auditors’ objectivity
and independence resulting from systematic rotation, but
has not considered whether control conscious organiza-
tions can implement the appropriate policies, procedures,
and oversight to effectively mitigate these risks.
Additionally, this paper demonstrates to researchers that
combining interview and archival data sources can pro-
duce interesting insights into important accounting mat-
ters that would not be attainable using only archival data.
Appendix A
Semi-structured interview protocol
We used the following interview protocol to guide our
interviews.
1. Descriptive information:
a. Organization Size, industry
b. IAF Size
c. Staf?ng
i. # of staff, managers, etc.
ii. Cosource? Outsource, etc.
d. IA plan or budget size
e. Types of audits conducted
f. Reporting lines
2. Systematic rotation of internal auditors into
management:
a. Do you use systematic rotation? (why or why not?)
b. Who makes the decision to use systematic
rotation?
c. Do auditors start in IA and rotate into the company
or can they come into IA after holding an opera-
tional position?
d. Which employees rotate out (All? Some? Staff only
– i.e., not CAE)?
e. Who decides who gets hired out of internal audit?
f. What is the time frame for rotation?
g. Is there a special skill set needed for rotation?
h. Do rotating internal auditors do different work
than other (career) internal auditors? (e.g., do they
only focus on consulting?)
3. Bene?ts & costs (risks) of systematic rotation:
a. What are the bene?ts of systematic rotation?
i. For the IA department/organization/rotating
auditor?
b. What are the risks of systematic rotation?
i. For the IA department/organization/rotating
auditor?
c. Financial reporting quality:
i. Does internal audit impact FRQ? (Why or why
not?)
ii. How (& why) does systematic rotation impact
this effect on FRQ?
d. Competence:
i. How does systematic rotation impact the com-
petence/expertise of internal auditors?
ii. How does systematic rotation impact the attrac-
tion of talent to internal audit?
29
We do not perform mediation analysis examining the effect of
systematic rotation on objectivity and competence, and then their effects
on FRQ because of the limitations of the empirical proxies for competence
and objectivity that we would have to employ. In particular, the proxies for
competence used in prior literature do not capture the nuances of how
systematic rotation affects competence as described by our interviewees
(e.g., enhanced knowledge of operations, etc.). Further, because objectivity
is an unbiased mental attitude, there are no empirical proxies for the
auditors’ state of mind. Prior research has used chief audit executive
reporting structure (i.e., IAF reporting to the audit committee versus
management) as a proxy for objectivity. However, our interviews suggest
that internal auditor objectivity is still subject to impairment despite
procedural controls aimed at ensuring independence as described in the IIA
Standards (such as reporting structure). Therefore, we include this measure
in our model as a compensating control and do not use it to proxy for
objectivity.
M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59 55
iii. How does systematic rotation impact the devel-
opment of internal auditors with internal audit-
ing skill sets?
iv. Do you think the external auditor would be
more (or less) likely to rely on the IAF because
it uses (does not use) systematic rotation?
e. Objectivity & independence:
i. How does systematic rotation impact objectivity
of internal auditors?
ii. How does systematic rotation impact indepen-
dence of internal auditors?
f. Do any of the above effects differ based on which
positions (staff or CAE) are systematically rotated
into management positions?
4. Other practices
a. Are there any mechanisms in place to enhance the
competence/objectivity of internal auditors who
are (to be) systematically rotated? (For example,
governance mechanisms.)
b. What practices could be put in place (either in their
organization or in another organization) to mini-
mize these potential negative effects?
5. Final Questions
a. How does your audit committee provide oversight
and monitoring over internal auditing function?
b. How does management impact the work and
results of the IAF?
c. Do you have any additional thoughts on the prac-
tice of rotating auditors into operational positions
you would like to share?
Appendix B
Variable descriptions
Where:
AuditCommittee A dichotomous variable taking
the value of 1 the audit
committee is has all ten
Blue-Ribbon Committee for Audit
Committee Effectiveness
attributes (BRC, 1999)
Age The years the company has been a
publicly listed company
computed by summing the
number of ?rm-years for which
they have data listed on
Compustat
Assets Total assets of a company (natural
log used in testing)
AR Accounting Risk, based on Audit
Integrity’s Accounting Risk
ranking (with governance
component removed). The
ranking ranges between 0 and
100, with 0 being the most
conservative ranking and 100
being the most risky.
a
Audit
Integrity estimates this measure
quarterly. We average the four
quarters for each year to come up
with an annual measure (natural
log used in model)
AuditSpecialist
b
A dichotomous variable that
indicates whether the external
auditor is an industry specialist
auditor or not. We de?ne industry
specialist auditor as a Big N audit
?rm that provides
within-industry market shares
30% greater than if the audit ?rms
were to split the industry evenly
among themselves
AuditFee The natural log of audit fees paid
by the company to their external
auditor
CAEAC A dichotomous variable
representing whether the chief
audit executive reports to the
audit committee (yes, CAEAC = 1;
no, CAEAC = 0)
CFO Cash ?ows from operations
Complexity The number of operating
segments that the company has
Experience Average number of years of
internal audit experience of the
internal auditors
FinRaised The sum of additional cash raised
from the issuance of common
and preferred stock and the
issuance of long-term debt
during the year divided by
average total assets
FinNeed A dichotomous variable equal to
one if the company’s free cash
?ow is less than À0.1, and zero
otherwise. Free cash ?ow is
calculated as Cash Flows less the
average capital expenditure over
the last three years, de?ated by
average total assets
Gindex Corporate governance metric
computed by Gompers et al.
(2003). Gindex is formed by giving
an organization a point for each
takeover defense or lack of
shareholder rights for 24 different
provisions. For years the metric
was not computed (i.e., 2001,
2003, and 2005), the average of
the metric for the year before and
after the missing year was used. A
higher value suggests that man-
agement has greater power,
which suggests lower corporate
governance quality
56 M.H. Christ et al. / Accounting, Organizations and Society 44 (2015) 37–59
IACompetence A single composite score
measuring the quality of the
IAF. The variable can range from
zero to ?ve with zero
representing the lowest quality
and ?ve representing the
highest quality. The score is
formed by assigning a value of
one to scores above the median
of the entire sample for
Experience, Certi?cation,
TimeFin, Training, and IASize,
and summing together.
IASize The average dollar amount spent
on internal auditing for the
industry divided by the average
total assets of the industry
subtracted from the dollar
amount spent on internal
auditing per company divided by
the company’s total assets. This
amount is then divided by the
average dollar amount spent on
internal auditing for the industry
divided by the average total
assets of the industry
IndustryDummies Dichotomous variables used to
represent different industries at
the one digit SIC code level
Lambda The inverse Mills’ ratio computed
from Eq. (1)
Leverage The sum of long term debt and
current liabilities of a company
divided by total assets
Loss A dichotomous variable
representing whether the
company experienced a loss in
the last ?scal year (yes, Loss = 1;
no, Loss = 0)
MB A company’s market-to-book
ratio
MeetOften A dichotomous variable equal to 1
if the chief audit executive meets
monthly or quarterly with the
audit committee and 0 otherwise
MeanIndRotate The average percentage of ?rms
that use systematic rotation at
the industry level
MGMTFocus A dichotomous variable taking
the value of 1 if management
expects internal audit to focus on
both risk assessments and
internal consulting on ?nancial
matters (versus a focus on
compliance (laws and
regulations) or internal
consulting on operational
matters)
Rotate A dichotomous variable equal to 1
if at least one of the RotateCAE,
RotateEmp, or RotateEmp
variables equaled 1 and 0
otherwise
RotateBoth A dichotomous variable
indicating whether the company
systematically rotates both staff
internal auditor positions and the
chief audit executive position or
not (yes = 1, no = 0)
RotateCAE A dichotomous variable
indicating whether the company
systematically rotates the chief
audit executive position or not
(yes = 1, no = 0)
RotateEmp A dichotomous variable
indicating whether the company
systematically rotates staff
internal auditor positions or not
(yes = 1, no = 0)
NYSE A dichotomous variable
indicating whether the company
is listed on the NYSE or not
(yes = 1, no = 0)
Outsource A dichotomous variable
indicating whether the company
outsources some or all of its IAF
work a third party provider or not
(yes = 1, no = 0)
QAR A dichotomous variable taking
the value of 1 if the IAF has had a
QAR (quality annual review) in
the last 3 years and zero
otherwise
Return The annualized buy-and-hold
return
Turnover The number of internal auditors
who left the IAF scaled by the
total number of internal auditors
in the IAF
YearDummies Dichotomous variables used to
represent each year in the sample
a
In the original Audit Integrity data, the scale is 0–100 but the riskiest
?rms have the lowest AR scores. We rescale the AR scores by subtracting
from 100 so that the interpretation of the AR scores is more intuitive (i.e.,
higher scores now indicate more risk).
b
We de?ne industry specialist auditor in a similar fashion to Mayhew
and Wilkins (2003) and Knechel, Naiker, and Pacheco (2007): an external
audit ?rm is considered the industry specialist (AuditorSpecialist = 1) if
the ?rm provides within-industry market share 30% greater than if the
audit ?rms were to split the industry evenly among themselves. We
measure within-industry market share using two-digit SIC code industry
listings. We use the threshold of 30% as industry specialists based on prior
research (e.g., Knechel et al., 2007; Mayhew & Wilkins, 2003). We note
that studies that examined questions during times that there were Big 8
and Big 6 audit ?rms in existence used thresholds of 15% (Krishnan, 2003)
to 20% (Dunn & Mayhew, 2004). Auditing ?rms that provide a substantial
portion of the auditing to an industry are likely to develop specialized
skills that enable them to perform more effective audits.
