Abstract We posit that the effect of non-audit fees on audit quality is conditional on the

extent of institutional monitoring. We suggest that institutional investors have incentives

and the ability to monitor financial reporting quality. Because of the reputation concerns

and potential litigation exposure, auditors are likely to provide high audit quality, when

they also provide non-audit services to clients, particularly when clients are subject to high

institutional monitoring. We find evidence that, as non-audit fees increase, audit quality

(measured by performance-adjusted discretionary current accruals and earnings-response

coefficients) reduces only for clients with low institutional ownership but not for clients

with high institutional ownership. Our results are robust after controlling for auditor

industry specialization, firms’ operating volatility, size effect, and potential endogeneity

between institutional ownership and audit quality.

1 Introduction

In this study, we investigate whether the relation between non-audit fees and audit quality

is contingent on the extent of institutional ownership. We posit and provide evidence that

impairment of audit quality is contingent on institutional monitoring—audit quality is less

likely to be impaired with the provision of non-audit services when the extent of external

monitoring by institutional investors is high. In doing so, we add to prior research that

documents mixed findings on the relation between non-audit service provision and audit

quality (e.g., DeFond et al. 2002; Frankel et al. 2002; Ashbaugh et al. 2003; Srinidhi and

Gul 2007; Krishnan et al. 2005; Francis and Ke 2006; Higgs and Skantz 2006) by showing

that the effects of non-audit services on audit quality are not apparent without also jointly

accounting for the effects of institutional ownership. We complement prior studies that

investigate the moderators on the relation between non-audit fees and audit quality (Lim

and Tan 2008; Duh et al. 2009; Hoitash et al. 2005) by suggesting that institutional

monitoring is another important mechanism that may mitigate the independence issue

arising from the provision of non-audit services.

Prior research indicates that the provision of non-audit services creates economic bonds

that weaken an auditor’s independence, and therefore, audit quality (DeAngelo 1981;

Simunic 1984; Beck et al. 1988). Concerns about reputation (Benston 1975; Watts and

Zimmerman 1983) and litigation exposure (Palmrose 1988; Shu 2000) are likely to motivate

auditors to be more independent in carrying out their audit and non-audit works. We posit that,

in the presence of high institutional monitoring, auditors are likely to maintain independence

and preserve audit quality when they provide non-audit services to their clients.

Despite the voluminous research investigating the effect of non-audit fees on audit

quality, none has considered the potential monitoring role of institutional investors. Previous

studies (e.g., Grossman and Hart 1980; Shleifer and Vishny 1986; Huddart 1993) suggest

that large shareholders have incentives to undertake monitoring or other costly control

activities when the increased returns from such monitoring activities are sufficient to cover

their associated costs. Because of the magnitude of wealth invested, institutional share-

holders are likely to actively monitor corporate affairs and monitor the quality of financial

statements’ information. To the extent that institutional investors are effective monitors, we

expect auditors to be concerned about their reputation, and possible litigation exposure if

they provide low quality in their assurance services. We posit that the association between

provision of non-audit services and impairment of auditor quality is moderated by the extent

of institutional monitoring, and that failure to account for this moderating role of institu-

tional investors can mask the relation between non-audit fees and auditor quality.

There is little consensus on what is the most appropriate proxy for audit quality and its

empirical measures are usually noisy. Hence, we conduct empirical tests using two proxies

of audit quality that have been used by prior studies. We infer improved audit quality from:

(a) lower performance-adjusted discretionary current accruals; and (b) stronger market’s

response to quarterly earnings surprises, i.e., earnings return coefficients (ERC). The first

measure is a proxy for actual (as opposed to perceived) audit quality, while the second

measure is a proxy for investors’ perception of audit quality.1 We measure economic

bonding with a client by the magnitude of non-audit fees and the relative importance of the

1 Prior studies also use the issuance of going concern opinions and incidence of restatements as alternativeproxies for audit quality (e.g., DeFond et al. 2002; Kinney et al. 2004). We do not use these two proxiesbecause of the small sample size. For example, the study by DeFond et al. (2002) only includes 96 firms thatreceive going concern opinions while the study by Kinney et al. (2004) has only 187 restating firms.

client. To provide a more complete coverage of the total economic bonding between

auditors and their clients, we also include total fees, which is the sum of both audit and

non-audit fees.2 Our primary motivation is to document whether sophisticated institutional

investors are likely to affect audit quality when auditors provide non-audit services to their

clients. To the extent that institutional investors perform an effective monitoring role, we

expect auditors to provide high audit quality when they also provide non-audit services to

firms with high institutional ownership.

Our results provide consistent evidence that, with increased non-audit fees, audit quality

is higher for firms with a greater level of institutional ownership compared to firms with a

lower level of institutional ownership. In the first proxy of audit quality (absolute level of

performance-adjusted discretionary current accruals), our sample consists of 5,951 firm-

year observations from 2000 to 2001. Depending on the proxies used for fees, we find

mixed evidence regarding the association between non-audit fees and discretionary current

accruals. However, we find that magnitude of non-audit fees and percentile rank of a

client’s non-audit fees interact significantly with institutional ownership in explaining the

level of discretionary current accruals. Specifically, an increase in non-audit services is

positively and significantly associated (negatively or not associated) with discretionary

current accruals for clients with low (high) institutional ownership.

In the second proxy of audit quality (earnings response coefficients), we employ a

sample of 3,425 firm-year observations from 2000 to 2001 to estimate these coefficients.

Across all the three fee measures, we find no evidence that earnings response coefficients

are lower for clients that pay high non-audit fees to external auditors. More importantly, we

find that, for all three fee measures, earnings response coefficients are significantly lower

(not significantly lower) for clients with low (high) institutional ownership.

Our paper contributes to the literature on the effect of non-audit service provision on

audit quality by providing the empirical evidence that this effect is conditional on insti-

tutional monitoring. The paper complements recent research that investigates the moder-

ators on the relation between non-audit fees and audit quality. Lim and Tan (2008) provide

some evidence that auditor specialization mitigates the economic bonding between audi-

tors and auditees, while Duh et al. (2009) and Hoitash et al. (2005) report that changes in

regulatory environment affect the relation between non-audit fees and audit quality. Our

study is closely related to Lim and Tan (2008) where they document that auditor spe-

cialization moderates the relation between non-audit fees and audit quality when an

earnings return relation is used as a proxy for audit quality, but not when discretionary

accruals are used. In contrast, we find that institutional ownership moderates the relation

between non-audit fees and audit quality when either discretionary accruals or the earnings

return relation is used as a proxy for audit quality. Our results are robust after explicitly

controlling for auditor specialization as in Lim and Tan’s (2008) study. In addition, in the

earnings return test, we find that auditor specialization moderates the relation between non-

audit fees and audit quality only when institutional ownership is low, but not when it is

high. This result suggests that the moderating role of audit specialists is present only in

firms with low institutional ownership. Our study thus complements Lim and Tan (2008)

by documenting the important monitoring role of sophisticated institutional investors in

moderating the association between non-audit fees and audit quality. This evidence is

important because recent regulatory initiatives have been directed at reducing the per-

ceived and actual threats of high non-audit fees on auditor independence, and that failure to

2 For brevity, we refer to all three measures as proxies for non-audit fees, although total fees (which includenon-audit fees) is more related to total economic bonding.

account for this moderating role of external monitors can mask the relation between fee

dependence and auditor quality.

The remainder of this paper is organized as follows. We discuss prior literature and

develop our hypotheses in Sect. 2. Section 3 describes our sample and variable mea-

surement. We present empirical results for the discretionary current accruals and earnings

return coefficients tests in Sects. 4 and 5, respectively. Section 6 discusses the sensitivity

analyses performed. Section 7 summarizes and concludes.

2 Related literature and hypotheses development

The SEC, accounting practitioners, and academic researchers have expressed concern

about the effect of fee dependence (primarily non-audit fee revenues) on auditor inde-

pendence. The provision of non-audit services can strengthen an auditor’s economic bond

with a client, and this bond can affect the objectivity of an audit (Simunic 1984; Becker

et al. 1998).3 Frankel et al. (2002) find a positive association between non-audit fees and

the magnitude of discretionary accruals. Similarly, Srinidhi and Gul (2007) report a neg-

ative association between non-audit fees and accrual quality computed from Dechow and

Dichev’s (2002) model. However, Ashbaugh et al. (2003) and Chung and Kallapur (2003)

do not find any relation between non-audit fees and discretionary accruals while Larcker

and Richardson (2004) find that non-audit fees are associated positively with various

measures of accruals only for firms with weak corporate governance. DeFond et al. (2002)

find that firms that pay high non-audit fees are not associated with the incidence of going

concern opinions, suggesting that auditor independence is not compromised with high non-

audit fees. Kinney et al. (2004) examine restated financial statements and find either no or

negative association between restatements and major classes of non-audit services. Hence,

there is no pervasive evidence indicating that high non-audit fees erode actual audit quality

as measured by discretionary accruals, issuance of going concern opinions, and the inci-

dence of financial restatements.

However, more recent evidence suggests that a high degree of fee dependence may

impair auditor independence. For example, using client-specific ex ante cost of equity as a

proxy for investor perceptions of financial reporting reliability, Khurana and Raman (2006)

find that high non-audit and total fees are associated with lower financial reporting cred-

ibility. Using earnings response coefficients as proxies for perceived audit quality (and

hence earnings quality), Francis and Ke (2006) report that the market valuation of earnings

surprises following the initial proxy statement fee disclosure is significantly lower for firms

with high non-audit fees than for firms with low non-audit fees. Similarly, Krishnan et al.

(2005) report a negative association between non-audit fees and earnings response coef-

ficients in each of the three quarters following the public disclosure of fee information in

the proxy statements. In contrast, Higgs and Skantz (2006) document a positive association

between earnings response coefficients and total fees, and limited evidence that non-audit

fees are associated with lower earnings response coefficients.

The inconclusive results in prior research suggest a lack of evidence that auditors ‘‘cave

in’’ to the demand of clients when the economic bonds between auditors and clients are

high. On one hand, previous research indicates that auditor’s provision of non-audit

3 For example, auditors are more likely to agree with managers’ financial-reporting preferences when therisk of losing the client is high (Farmer et al. 1987) and when accounting standards require a greater level ofjudgment (Magee and Tseng 1990; Trompeter 1994).

services creates economic bonds on the auditor and may potentially cause the auditor to be

financially reliant on the client (DeAngelo 1981; Simunic 1984; Beck et al. 1988) and lose

objectivity. On the other hand, prior research also indicates several factors that counter

these incentives that dilute auditors’ objectivity—reputation concerns (Benston 1975;

Watts and Zimmerman 1983) and litigation exposure (Palmrose 1988; Shu 2000). Whether

auditors’ independence and audit quality are impaired when they provide non-audit ser-

vices is a function of the net balance of the economic dependency arising from non-audit

service provision, and the mitigating factors that promote auditor independence. We posit

that monitoring by institutional investors can act as a mitigating factor that promotes

auditor independence.

Institutional investors are often characterized as sophisticated investors with incentives

to monitor the quality of financial reporting. First, financial statements are an important

source of information about the firm that institutional investors mostly rely on. Second,

institutional investors are capable of analyzing financial statements more thoroughly and

proficiently than individual investors. For example, Hand (1990) finds that sophisticated

investors more accurately interpret information in earnings announcements. Bartov et al.

(2000) find that the pattern of post earnings announcement drift documented in the prior

literature (e.g., Bernard and Thomas 1990) is reduced as the level of institutional invest-

ment increases.

Third, institutional investors are not only sophisticated investors who use and under-

stand accounting information, but are capable monitors as well. Institutional monitoring

can occur explicitly through corporate governance practices or implicitly through infor-

mation gathering and by correctly pricing the impact of managerial decisions (Kao 2007).

Gillan and Starks (2000) note that shareholder activism can take several forms, such as

submitting a shareholder proposal to the proxy statement, direct negotiation with the

management, or public targeting of the firm. Shareholder activism is more likely when

institutional investors own a large portion of the firms’ shares. Consistent with this view,

Brickley et al. (1988) find that institutions tend to oppose managerial decisions that are

harmful to shareholders. Fourth, institutional investors improve the information environ-

ment and earnings quality of the firms they invest in. For example, Ajinkya et al. (2005)

find that firms with greater institutional ownership are more likely to issue more frequent,

more specific, and more accurate forecasts. Because of their access to timely and valuable

sources of firm-specific information, institutional investors recognize earnings manage-

ment more quickly and easily than individual investors (Balsam et al. 2002) and, corre-

spondingly, earnings quality is higher for firms with greater institutional ownership (Chung

et al. 2002, 2005; Mitra and Cready 2005; Jiambalvo et al. 2002; Kwak et al. 2009).

In summary, institutional investors have incentives to monitor the quality of financial

reporting and the power to discipline managers who report low quality accounting figures.

In the presence of high institutional monitoring, auditors are more likely to be independent

and more concerned about their reputation and the possible litigation exposure arising from

low audit quality performed. Velury et al. (2003) and Kane and Velury (2004) report that

institutional investors tend to influence managers of firms to hire high-quality auditors to

enhance the credibility of financial reporting. Prior studies show that high-quality auditors

provide high quality audits to protect their reputations (e.g., Becker et al. 1998; Teoh and

Wong 1993). The threat of litigation also provides auditors the incentive to provide high

quality audits for their audit clients (Francis and Krishnan 2002). Given the substantial

direct and indirect costs of potential litigation (i.e., settlements costs, damage to reputation,

and opportunity costs in terms of time away from more productive efforts), the higher the

risk of litigation, the greater will be the auditor’s incentives to perform diligently. Hence,

Non-audit fees, institutional monitoring, and audit quality 347

123

Page 6: Non-audit fees, institutional monitoring, and audit quality

when client firms are closely monitored by influential institutional investors, auditors are

more likely to protect their reputation and, at the same time, avoid costly litigation in the

case of audit failure by providing higher audit quality.

Based on the discussions above, we posit that the presence of high institutional own-

ership should provide a countervailing force for the auditors to remain independent and

provide high audit quality when they also provide non-audit services to clients. We suggest

that the association between non-audit fees and audit quality is likely moderated by the

extent of institutional ownership. Specifically, the provision of non-audit services is less

likely to impair audit quality for firms with high institutional ownership compared to firms

with low institutional ownership. We test the following hypothesis (stated in alternative

form):

H1 Audit clients with low institutional ownership will have lower audit quality when

non-audit fees increase than clients with high institutional ownership.

This hypothesis is tested using two proxies for audit quality: performance-adjusted

discretionary current accruals and earnings return coefficient.

3.1 Data

Our initial sample consists of 13,789 firm-years with fee information from the Audit

Analytics database for fiscal years 2000–2001. We do not include year 2002 (and beyond)

because the year 2002 is associated both with the demise of Arthur Andersen and the

effective banning of auditors from performing various kinds of non-audit services by

the Sarbanes–Oxley Act. These two events may have undue influences on the firms, and

the audit and stock market during that year. We remove 3,855 firm-years without financial

information in the Compustat database. We restrict our study to clients of Big 5 auditors to

control for brand name (Chung and Kallapur 2003; Srinidhi and Gul 2007; Lim and Tan

2008). Accordingly, we remove 1,718 firm-years that are not audited by Big 5 auditors.

Given the fundamentally different operating characteristics associated with financial

institutions, we exclude 961 financial companies from the analyses (SIC Codes

6000–6999). We next remove 824 firms without institutional ownership data in Thomson

Financial database. The above screening procedure yields a remaining sample of 6,431

firm-year observations.4 We winsorize each of the continuous control variables used in the

regression at the top and bottom one percent. For our first proxy of audit quality, discre-

tionary current accruals, we have 5,951 firm-years over 2000–2001 with all available

financial data in Compustat. The sample for our second proxy of audit quality, earnings

return coefficients, contains 3,425 firm-year observations with complete information on the

control variables from Compustat, I/B/E/S detailed files, and CRSP databases.

Panels A and B in Table 1 report the distribution of sample firms by year and industry,

respectively, for the two sets of data used for the discretionary current accruals and

earnings return regression tests.

4 Bushee (2001) classifies institutions into three categories: transient institutions, which hold diversifiedportfolios with high turnover; dedicated institutions, which hold concentrated portfolios with low turnover;and quasi-indexers, which hold diversified portfolios with low turnover. We use aggregate institutionalownership due to data unavailability.

3.2 Non-audit fees

Prior studies (e.g., Frankel et al. 2002) use the ratio of non-audit fees to total fees to proxy

for fee dependence and, hence, auditor independence. However, the validity of this mea-

sure as a proxy of an audit firm’s economic bond has been questioned (e.g., Kinney and

Libby 2002). Some researchers argue that fee level (DeFond et al. 2002; Ashbaugh et al.

2003) or client importance (Chung and Kallapur 2003) are better measures. Hence, for

completeness, we use three measures to capture the economic bonding between the clients

and auditor: (1) the natural log of non-audit fees (LNAU), which captures the level of

economic bonding resulting from the purchase of non-audit services, (2) the percentile rank

of a particular client’s non-audit fees given all total fees received by the audit firm

(PRNAU), which captures the relative significance of client non-audit fees to the total fees

revenue received by the auditor, and (3) the natural log of total fees (LTOT), which

captures the total economic bonding of the client to the auditor created by the provision of

both non-audit and audit services.5

4 Discretionary current accruals

4.1 Empirical model

Following prior studies (e.g., Ashbaugh et al. 2003; Lim et al. 2008), we compute perfor-

mance-adjusted discretionary current accruals (PA_DCA) based on the cross-sectional

modified Jones (1991) model for all firms recorded in Compustat. We define current accruals

(CA) as income before extraordinary items plus depreciation and amortization minus oper-

ating cash flows. To obtain the PA_DCA in a given year, we regress the following:

CAi;t

TAi;t�1

¼ k1

1

TAi;t�1

� �þ k2

DREVi;t

TAi;t�1

� �þk3

IBi;t�1

TAi;t�1

� �þ ei;t ð1Þ

where CAi,t is the current accruals for firm i in fiscal year t, TAi,t-1 is the total assets for

firm i in fiscal year t-1; DREVi,t measures the change in revenues for firm i in year t less

revenues in t-1; IBt-1 is the income before extraordinary items in year t-1; and ei,t is the

random residual term. Similar to previous studies, we estimate Eq. (1) cross-sectionally on

all firms recorded in Compustat with the same two-digit SIC industry. PA_DCA are then

estimated as:

PA DCAi;t ¼CAi;t

TAi;t�1

� �� k̂1

1

TAi;t�1

� �� k̂2

ðDREV � DTRÞi;tTAi;t�1

� �� k̂3

IBt�1

TAt�1

� �ð2Þ

where k̂j; for j = 1, 2, and 3, are the estimated parameters from Eq. (1) and DTRi,t is the

change in trade receivables for firm i in year t less the trade receivables in the previous year.

Consistent with Frankel et al. (2002), Ashbaugh et al. (2003) and Lim and Tan (2008),

we run the following model to test the association between non-audit fees and discretionary

current accruals:

APA DCA ¼ x0 þ x1FEEþ x2TENUþ x3CFOþ u4LEVþ x5LITIGþ x6MB

þ x7SIZEþ x8LOSSþ x9FINþ x10LAG ACAþ x11ZSþ x12SPEC

þ x13INSTþ x14Y00þ x15FEE � SPECþ x16FEE � INSTþ e ð3Þ

APA_DCA = absolute value of the performance-adjusted discretionary current accruals

estimated with lagged ROA in the cross-sectional Jones model;

5 The distribution of the non-audit fees and total fees are non-normal, and hence following prior studies(e.g. Frankel et al. 2002; DeFond et al. 2002), we log-transformed the non-audit and total fee variables. Ourmeasure for client importance (ratio of non-audit fees to total fees received by the auditor) is also non-normal and highly skewed. Hence, we follow Frankel et al. (2002) and Lim and Tan (2008) by rank-transforming the variable. The rank-transformation substantially reduced the skewness and kurtosis of thevariable.

INST = percent of the company’s aggregate common stock held by institutions;

Y00 = year dummy.

We include the FEE*INST interaction term in the regression model to test the associ-

ation of non-audit fees on absolute level of performance-adjusted discretionary current

accruals, conditional on institutional ownership. Based on our hypothesis, we expect the

coefficient for FEE*INST (x16) to be negative. A negative x16 indicates that non-audit fees

are associated with lower APA_DCA when level of institutional ownership increases.

Consistent with Lim and Tan (2008), we also include an interaction term FEE*SPEC to

assess the moderating role of auditor specialization. More importantly, we assess whether

institutional ownership plays an important moderating role after controlling for the mod-

erating role of auditor specialization.

4.2 Empirical results

We report the descriptive statistics and the correlation coefficients for the fee metrics and

variables used in the discretionary current accruals model in Table 2. The mean (median)

absolute value for APA_DCA is 0.267 (0.096).7 On average, 40 % of the firms’ shares are

held by institutions and 24 % of the firms are audited by audit specialists. Other variables

used in discretionary accruals regression, and the correlation coefficients among them, are

also reported in Table 2.

We report the regression results for the absolute discretionary current accruals for the

full sample in Table 3, Panel A. The adjusted R2 is around 19 %, compared to the adjusted

R2 of 18–21 % reported in Ashbaugh et al. (2003). In the models with FEE, INST alone

(without the interaction term FEE*INST), the association between non-audit fees and

discretionary current accruals varies depending on the different proxies used. We find no

association between LNAU and discretionary current accruals (Ashbaugh et al. 2003) while

PRNAU is positively and significantly associated with discretionary current accruals

6 According to Zmijewski (1984), a positive score is an indicator of greater than 50 % likelihood ofbankruptcy.7 The apparent high mean and median values of APA_DCA is due to the absolute transformation. Thesigned mean and median discretionary current accruals are -0.062 and -0.018 respectively.

Non-audit fees, institutional monitoring, and audit quality 357

Page 16: Non-audit fees, institutional monitoring, and audit quality

(Srinidhi and Gul 2007). However, we find that total fees are negatively and significantly

associated with discretionary current accruals.8 The coefficient estimate for INST is neg-

ative and significant at the 1 % level, consistent with the argument that institution investors

are effective monitors in constraining firms’ earnings management.

We then include the interaction terms (FEE*INST and FEE*SPEC) in the models.

Consistent with our prediction in H1, the coefficient estimate for the interaction term

(FEE*INST) is negative and statistically significant when FEE is measured by LNAU and

PRNAU, which suggests that increased non-audit fees are associated with higher audit

quality when institutional ownership increases. However, we do not find significant

interaction when FEE is measured by LTOT. Hence, our results for the interaction effect

are sensitive to the proxies used to measure fee dependence. Consistent with Lim and

Tan (2008), the coefficient estimate for the interaction term (FEE*SPEC) is insignificant

in all three models.

We next partition the sample into two groups based on median institutional ownership.

The results are reported in Panel B of Table 3. For the firms with high institutional

ownership, PRNAU is not associated with APA_DCA, while LNAU and LTOT are nega-

tively and significantly associated with APA_DCA. For the firms with low institutional

ownership, LNAU and PRNAU are positively and significantly associated with APA_DCA,

while LTOT is not associated with APA_DCA. These results are consistent with the con-

tention that audit quality is reduced only for firms with low institutional ownership, but not

for firms with high institutional ownership. Again, we find that FEE*SPEC is not asso-

ciated with APA_DCA for both subsamples. Taken together, our results suggest that

institutional investors, rather than audit specialists, moderate the relation between non-

audit fees and audit quality measured by discretionary current accruals.

Overall, our results suggest a moderating effect of institutional ownership on the

association between non-audit fees (measured by LNAU and PRNAU) and performance-

adjusted discretionary current accruals.

5 The earnings return regression

5.1 Empirical model

We use the earnings response coefficients (ERC) from the returns-earnings regressions as a

proxy for investor perceptions of earnings quality (Francis and Ke 2006; Ghosh and Moon

2005, 2010). The fee information is only made available to investors when firms file their

10 K reports with the SEC. Hence, we use short-window returns to infer the effect of non-

audit fees (together with institutional ownership) on audit quality. Specifically, we measure

three-day cumulative abnormal returns for days -1, 0, and 1, where day 0 is the day of

quarterly earnings announcement immediately after fee disclosure in the proxy statements,

where abnormal returns is defined as the difference between a firm’s returns and the CRSP

8 Total fees are the aggregate value and are meaningful only if both the audit and non-audit fees havesimilar effects on economic bonding. Srinidhi and Gul (2007) find that audit (non-audit) fees are positively(negatively) associated with accrual quality. Hence, our results suggest that the negative relation betweentotal fees and discretionary current accruals is driven by the beneficial effect of audit fees on audit quality.Our untabulated results indicate that audit fees are negatively and significantly associated with discretionarycurrent accruals (t = -3.11, p \ 0.01).

value-weighted market returns (Francis and Ke 2006).9 Based on prior studies (e.g.,

Francis and Ke 2006; Ghosh and Moon 2005), we run the following regression:

CAR ¼ a0 þ a1ðUEÞ þ a2ðFEEÞ þ a3ðUE � FEEÞ þ a4ðMBÞ þ a5ðUE �MBÞþ a6ðLEVÞ þ a7ðUE � LEVÞ þ a8ðPERSÞ þ a9ðUE � PERSÞþ a10ðBETAÞ þ a11ðUE � BETAÞ þ a12ðVOLÞ þ a13ðUE � VOLÞþ a14ðAGEÞ þ a15ðUE � AGEÞ þ a16ðREGÞ þ a17ðUE � REGÞþ a18ðSIZEÞ þ a19ðUE � SIZEÞ þ a20ðLOSSÞ þ a21ðUE � LOSSÞþ a22ðRESTRÞ þ a23ðUE � RESTRÞ þ a24ðSPECÞ þ a25ðUE � SPECÞþ a26ðINSTÞ þ a27ðUE � INSTÞ þ a28ðFEE � SPECÞ þ a29ðFEE � INSTÞþ a30ðUE � FEE � SPECÞ þ a31ðUE � FEE � INSTÞþ a32ðY00Þ þ a33ðUE � Y00Þ þ e ð4Þ

where

CAR = three-day cumulative abnormal returns around the first quarterly earnings

announcement after the fee discourse in the proxy statements;

UE = earnings surprise, measured by the difference between actual earnings per share

and most recent median earnings forecast for the quarter immediately after the

disclosure of fee information in the proxy statement, scaled by stock price at the

beginning of the quarter. Both actual and forecasted earnings per share are from I/B/E/S

detailed files;

FEE = fee metrics, LNAU, PRNAU, and LTOT, as defined earlier;

MB = market-to-book ratio at end of quarter;

LEV = debt-to-equity ratio at end of quarter;

PERS = earnings persistence measured by the first-order autocorrelation of earnings

before extraordinary items per share for the past 16 quarters;

BETA = beta estimated from daily stock returns over a 90-day window ending 7 days

prior to the earnings announcement date;

VOL = the variance of the residual from the market model over a 90-day window

ending 7 days prior to the earnings announcement date;

AGE = number of years that the firm is publicly traded as of the fiscal year end;

REG = an indicator equals one for firms in a regulated industry (two-digit SIC 40–49

and SIC 60–63), and zero otherwise;

SIZE = natural log of market capitalization at end of quarter;

LOSS = 1 if the current quarter’s earnings is negative, and 0 otherwise;

RESTR = 1 if the special item as a percentage of total assets in the quarter is less than or

equal to -5%, and 0 otherwise;

SPEC = 1 if the auditor has the largest market share in the industry, and 0 otherwise;

INST = percent of the company’s aggregate common stock held by institutions;

Y00 = year dummy.

The coefficient for UE*FEE*INST (a31) shows the incremental effect of INST on ERC

when non-audit fees increase. To the extent that the audit quality is higher for firms with

9 The Audit Analytics database record the date when proxy statements on fee information are filed with theSEC. Most filings occur three to 4 months after the fiscal year end. We tracked the dates recorded in AuditAnalytics to ensure that the fee information is available to investors when firms make the first quarterlyearnings announcements after the fiscal year end.

Non-audit fees, institutional monitoring, and audit quality 359

123

Page 18: Non-audit fees, institutional monitoring, and audit quality

high institutional ownership when non-audit fees increase, we expect the coefficient for

UE*FEE*INST to be positive. Following Lim and Tan (2008), we control for the mod-

erating effect of auditor specialization by including SPEC, UE*SPEC, FEE*SPEC and

UE*FEE*SPEC in the model. We also run Eq. (4) separately (without the variables–INST,

FEE*INST and UE*FEE*INST) for firms with high/low level of institutional ownership

based on median institutional ownership. To the extent that institutional investors provide

an effective monitoring role and that auditors are therefore likely to provide high audit

quality, we expect non-audit fees to be associated with lower ERC only for firms with low

institutional ownership but not firms with high institutional ownership.

5.2 Empirical results

We report the descriptive statistics and the correlation coefficients for the variables used in

the earnings return regression model in Table 4. On average, 52 % of company’s shares are

held by institutions and 24 % of firms are audited by audit specialists. The mean (median)

three-day cumulative abnormal returns (CAR) are 1.2 % (0.50 %). The mean (median)

earnings surprise is 0.2 % (0 %) of the stock price at the beginning of the quarter. Other

variables used in the earnings return regression, and the correlation coefficients among

them, are also reported in Table 4.

We report the results for the earnings return regression in Table 5. Panel A reports the

results for the ERC test for the full sample. In the models without the interaction terms

FEE*INST and UE*FEE*INST, the three proxies for fees are not associated significantly

with ERC. This result is inconsistent with Francis and Ke (2006) and Krishnan et al.

(2005) but is consistent with Higgs and Skantz (2006). Audit quality is not perceived to

be lower with high fees. In line with prior studies that document the information role of

institutional investors (e.g., Jiambalvo et al. 2002), INST is associated significantly with

higher ERC. For the set of control variables, firms audited by audit specialists, high

growth firms and firms in regulated industry are associated with higher ERC. On the

other hand, older firms, firms making losses, firms that restructure their operations and

risky firms (measured by VOL) are associated significantly with lower ERC. Other

control variables are not statistically significant.

We then include the interaction terms, FEE*INST, UE*FEE*INST, FEE*SPEC and

UE*FEE*SPEC in the models. Consistent with our prediction in H1, the coefficient

estimate for the interaction term (UE*FEE*INST) is positive and statistically significant

at the 1 % level for all three fee measures. The results indicate that, as non-audit fees

increase, audit quality is higher for firms with high level of institutional ownership.

Consistent with Lim and Tan (2008), we also find that the coefficient estimate for the

interaction term (UE*FEE*SPEC) is positive and statistically significant at the 5 %

level.

Next, we split the sample into two groups based on median institutional ownership.

The results are reported in Panel B of Table 5. Consistent with our prediction, for firms

with high institutional ownership, all three fee measures are not associated with lower

ERC. In contrast, for firms with low institutional ownership, all three fee proxies are

associated significantly with lower ERC. Interestingly, the coefficient estimate for the

interaction term (UE*FEE*SPEC) is positive and statistically significant only for firms

with low institutional ownership but not for firms with high institutional ownership. The

results suggest that the moderating role of audit specialists is present only in firms with

low institutional ownership.

Page 27: Non-audit fees, institutional monitoring, and audit quality

Overall, our results are consistent with the prediction in H1, and indicate that, as non-

audit fees increase, earnings response coefficients (and hence audit quality) correspond-

ingly reduces only for firms with low institutional ownership, but not for firms with high

institutional ownership.

6 Additional analyses

6.1 Control for operating volatility

Hribar and Nichols (2007) show that the error variance in the discretionary accrual esti-

mation models is associated with operating volatility. Hence, following their recommen-

dation, we include standard deviation of operating cash flow (rCFO) and standard deviation

of sales (rREV) in Eq. (3) as additional independent variables. Both variables are deflated

by total assets, over the current and prior 4 years. The results are reported in Table 6.

Consistent with the evidence reported in Hribar and Nichols (2007), both rCFO and rREV

are positive and significantly associated with APA_DCA at the 1 % level. The coefficient

estimates for the interaction term (LNAU*INST) and (PRNAU*INST) are still negative and

significant at the conventional levels. Our results are robust after controlling for firms’

operating volatility and that our main results are not driven by omitted correlated variables.

6.2 Alternative proxy for performance-adjusted discretionary current accruals

Prior research documents that discretionary accrual estimates are correlated with firm

performance (e.g., Kothari et al. 2005). In the main test, we adjust performance by

including a lagged ROA in the modified Jones (1991) model. As a robustness check, we

compute an alternative proxy for performance-adjusted discretionary current accruals. As

suggested by Kothari et al. (2005) and consistent with Ashbaugh et al. (2003), we array

firms in each industry (by two-digit SIC code) into deciles based on the prior year’s return

on assets (ROA), and obtain the performance-adjusted abnormal accruals by subtracting

from each firm’s abnormal accrual the median abnormal accrual from the corresponding

ROA industry decile to which the firm belongs. We then take the absolute value of the

accruals measure. Our untabulated results indicate that our main results still hold with this

alternative proxy for discretionary current accruals. Specifically, the coefficient for

LNAU*INST and PRNAU*INST are both negative and significant at the 1 % level for the

full sample. Splitting the sample into high or low institutional ownership, the coefficient

for LNAU and PRNAU are positive and significant at the 5 % level for firms with low

institutional ownership, but insignificant for firms with high institutional ownership.

6.3 Fee ratio as a proxy for fee dependence

The ratio of non-audit fees to total fees as a proxy for fee dependence has been criticized in

the prior literature (e.g., Kinney and Libby 2002). Nevertheless, we investigate the effect of

the fee ratio on audit quality on the full sample since the original regulatory concern about

auditor independence is that non-audit fees exceeds audit fee.

In the accruals test, consistent with Frankel et al. (2002), our untabulated results indicate

that fee ratio (FEERATIO) is positively associated with APA_DCA at the 1 % level.

Further, we find that the coefficient for the interaction term (FEERATIO*INST) is negative

and significant at the 1 % level. We obtain similar results for the ERC test. Specifically, the

coefficient for UE*FEERATIO is negative and significant at the 1 % level. In addition, the

coefficient for UE*FEERATIO*INST is positive and significant at the 1 % level. Overall

our results suggest that audit quality is indeed lower when the proportion of non-audit fees

is high relative to total fees. However, the negative effect of fee ratio on audit quality is

moderated by the presence of high institutional ownership.

6.4 Size effect and multi-collinearity

Since many variables used in the regression analyses are correlated with SIZE, we perform

a sensitivity analysis to test whether the study’s main results are confounded by size

effects. There is high correlation between firm size and fee proxies (ranges from 0.66 to

0.70, see Panel B of Tables 2 and 4). The high correlations also raise concerns about multi-

collinearity in the analysis. To ensure that our results are not spurious due to the high

correlations between fees and firm size, following Simunic (1984) and Abbott et al. (2003),

we deflate non-audit and total fees by the square root of total assets and regress the deflated

non-audit fees (NAU/TA) and deflated total fees (TOT/TA) on APA_DCA and ERC in the

presence of other controls except SIZE. The results are reported in Table 7. For the

accruals test (reported in Panel A), the coefficient estimates for the interaction term

between fees and institutional ownership are negative and significant for NAU/TA and

TOT/AT at 5 % level or lower. In the ERC test (reported in Panel B), the coefficient

estimates for the interaction term, UE*FEE*INST, are positive and significant at the 1 %

level, when fees are measured by both NAU/AT and TOT/AT. Overall, these findings are

consistent with the main results reported in Tables 3 and 5.

The correlations between size and institution ownership are also high (0.67 and 0.5, see

Panel B of Tables 2, 4), which raises the possibility that fees and institutions are substitutes

and not distinct constructs. If this were the case, it would imply that our findings of an

interaction between INST by FEE should be replicated when we replace INST with firm

size. On the other hand, if they are distinct constructs, the results may be distinct. We

report the results for the accruals and ERC tests in Panel A and B of Table 8, respectively.

For the accruals test, we exclude INST but include FEE, SIZE, and their interaction in

the models. Our results indicate that the coefficients of the interaction term FEE*SIZE are

all insignificant across the three fee measures whereas, in our main analysis, we find the

coefficient of the interaction term FEE*INST to be negative and significant when fee is

measured by LNAU and PRNAU.

For the ERC test, we exclude INST but include FEE, SIZE, and their interactions with

UE in the models. If firm size and institutional ownership are indeed the same construct,

then we will expect the coefficient for UE*FEE*SIZE to be positive and significant.

However, we find that the coefficients for UE*FEE*SIZE are insignificant in all models,

whereas, in our main analysis, we find that the coefficients for UE*FEE*INST are positive

and significant in all models. Taken together, our findings for the accruals and ERC tests

suggest that institutions and firm size are different constructs.

Lastly, to further address any concerns about multi-collinearity, we check the variance-

inflation factors (VIF) of the variables in the regression model. In the accruals test, we find

that the VIF for all the variables (including the interaction terms) are less than ten. In the

ERC test, the threat of multi-collinearity is higher because of the many interaction terms

included in the model. We examine the VIF for the subsample of firms with high and low

institutional ownership. All the variables (including the interaction terms) have VIF less

than ten, with the exception for UE*SIZE (with VIF ranging from 24 to 78). These VIF

values appear large and may pose a threat to the reliability of the inferences made.

However, the concern is somewhat mitigated because, from the results of our sensitivity

tests, our main findings do not appear to be driven by the firm size effect. Notwithstanding

this, our results should be interpreted with caution as we cannot resolve completely the

multi-collinearity problem in the ERC test.

6.5 Endogeneity between institutional ownership and audit quality

The relation between audit quality (measured by discretionary current accruals and ERC)

and institutions may be endogenous. Institutional investors may choose to invest in firms

with low discretionary accruals or high ERC. To address this potential endogeneity issue, we

employ a two-stage least-squares analysis by using the following first-stage regression to

cross-sectionally estimate the intercept and coefficients of the determinant variables of INST:

INST ¼ b0 þ b1APA DCAþ b2SIZE þ b3SQSIZE þ b4LITIGþ b5MBþ b6LOSS

þ b7DIVIDENDþ b8LIQUIDITY þ b9SNPþ b10LAG RET þ b11Y00þ e ð5Þ

where

SQSIZE = squared term of SIZE;

DIVIDEND = dividend pay-out ratio;

LIQUIDITY = log(trading volume/shares outstanding);

SNP = 1 if the company is part of the S&P 500, and 0 otherwise;

LAG_RET = stock returns for the previous fiscal year;

Other variables are as defined in Eq. (3).

The instrumental variables for Eq. (5) are drawn from Jiambalvo et al. (2002) and

Ajinkya et al. (2005). Institutions prefer to invest in large firms (measured by SIZE),

although their demand for stocks is a concave function of firm’s market capitalization

(measured by SQSIZE). Furthermore, institutions prefer to invest in liquid stocks (LIQU-

DIITY), firms that are listed in S&P500 (SNP) and firms that have lower returns in the

previous year (LAG_RET). Institutions also tend to avoid investing in loss-making firms

(LOSS), firms with high dividend yield (DIVIDEND) and market-to-book ratios (MB). We

compute the inverse Mills ratio (IMR) from stage one regression. In the second stage, we

estimate Eqs. (3) and (4) after including IMR as an additional independent variable.

The results for the first-stage regression are reported in Panel A of Table 9. Most

variables are significant and behave as conjectured. Institutional investors tend to invest in

large firms, firms with high accrual quality, and more liquid stocks. They also tend to

invest less in loss-making firms, dividend-paying firms, firms with high market-to-book

ratio, and firms with high past stock returns. The adjusted R-square for the model is 50 %.

We report the second-stage regression results for the accruals and ERC tests in Panel B

and C of Table 9 respectively, with IMR as an additional independent variable. For the

accruals test, IMR is positive and significantly associated with APA_DCA in all three

models. After controlling for the self-selection problem, the interaction term (FEE*INST)

is negative and significant at conventional level for all three fee proxies, consistent with

our main results. For the ERC test, IMR is not associated with ERC, and the coefficients for

UE*FEE*INST continue to be significant at 1 % level in all three models.

Overall, the results reported in Table 9 are similar to those reported in Tables 3 and 5;

our main results are not likely driven by the potential endogeneity between institutional

ownership and audit quality.

6.6 Inclusion of firms audited by non-Big 5 auditors

In this study, we only include firms audited by Big 5 auditors in the sample to control for

the effect of brand name (e.g., Lim and Tan 2008). We test the robustness of our results

when we also include firms audited by non-big 5 auditors.10 Specifically, in the accruals

test, we include an additional dummy for Big5 (1 if the firm is audited by a Big 5 auditor

and 0 otherwise) while in the ERC test, we include Big5 and UE*Big5 in the regression

model. Our main results are robust with the inclusion of these variables. Specifically, in the

accruals test, the coefficient for FEE*INST is negative and significant at the 1 % level

when fee is measured by LNAU and PRNAU. In the ERC test, we continue to find all three

proxies for fee to be negatively associated with ERC at the 1 % level for firms with a low

level of institutional ownership but not for those whose institutional ownership is high.

Overall, our inferences remain unchanged when we also include firms audited by non-Big

5 auditors in the sample.

6.7 Removing firms from dominant industries

Firms from two industries (computers and durable manufacturers) comprise more than

40 % of the total sample, see Panel A of Table 1). We conduct additional sensitivity

analysis by excluding firms in these two industries. The results (untabulated) are robust for

both the accruals- and ERC- tests. Specifically, in the accruals test, the coefficient for

To address the potential endogeneity between institutional ownership and audit quality, we employ a two-stage least-squares analysis. We report the results for the first stage in this table. Panel A reports the resultsfor running the following first-stage regression: INST ¼ b0 þ b1APA DCAþ b2SIZE þ b3SQSIZE þb4LITIGþ b5MBþ b6LOSSþ b7DIVIDENDþ b8LIQUIDITY þ b9SNPþ b10LAG RET þ b11Y00þ ewhere SQSIZE is the squared term of SIZE; DIVIDEND is dividend pay-out ratio; LIQUIDITY is log oftrading volume divided by number of shares outstanding; SNP is an indicator variable, coded 1 if thecompany is part of the S&P 500, and 0 otherwise. LAG_RET is the stock returns for the previous fiscal year.Other variables are as defined in footnotes of Table 2. The inverse-Mill-ratio is computed from stage oneregression and is included as an additional independent variable in stage-two regression. We report theresults for the second-stage regression for the accruals and ERC tests in Panel B and C. The models used inaccruals and ERC tests, are same as those reported in Tables 3 and 5, respectively. ‘*’, ‘**’, and ‘***’denote significance at 10, 5, and 1 % levels (two-tailed), respectively

10 The number of firms audited by non-Big 5 auditors and the extent of institutional ownership of thesefirms are very small in comparison to firms audited by Big 5 auditors. For example, in the discretionarycurrent accruals test, 772 firms are audited by non-big 5, compared to 5,951 firms audited by Big 5. Themean (median) institutional ownership of firms audited by non-big 5 auditors is only 13 % (4 %) whereasthe mean (median) institutional ownership of firms audited by Big 5 auditors is 40 % (39 %). Hence, we donot include those firms audited by non-Big 5 auditors in our main analysis because of the small number andlow institutional ownership.

FEE*INST is negative and significant when fee is measured by LNAU and PRNAU while in

the ERC test, the coefficient for UE*FEE*INST is positive and significant for all three fee

measures.

7 Conclusion

Recent studies on whether the provision of non-audit services impairs auditor indepen-

dence and audit quality have found mixed results, depending on the proxy for audit quality

used. We posit and provide consistent evidence that external monitoring by institutional

investors affects the association between non-audit fees and audit quality. We argue that

sophisticated institutional investors play an active monitoring role in influencing firms’

financial reporting. Auditors are likely to be more independent and preserve audit quality

due to their concerns about reputations and litigation exposure when they also provide non-

audit services to clients.

Our empirical results indicate that the relation between non-audit fees and audit quality

is contingent on the extent of institutional monitoring. We document that, as non-audit fees

increase, audit quality is reduced only for firms with low institutional ownership, but audit

quality is not impaired for firms with high institutional ownership. Our results lend support

for the beneficial monitoring effect of financial intermediaries in mitigating the potential

impairment of auditor independence arising from high fee dependence between clients and

auditors. Our results remain robust even after controlling for auditor industry specializa-

tion, firms’ operating volatility, the size effect, and the potential endogeneity between

institutional ownership and audit quality.
