Ownership of the public corporations across the world is not sow i d e l y d i s p e r s e d . I n s t e a d , h i g h e r o w n e r s h i p c o n c e n t r a t i o n
somehow prevails in the developed countries as well as in the

ownersh ip s t ruc tu res1) typical among East Asian companies (Fan
and Wong 2002). Among these companies, controlling owners in
the region usually have higher level of control r ights than the
level of their equity ownership. Therefore, there exists divergence
between cash flow rights and voting rights. In prior accounting
and finance literature, this divergence is widely used as a proxy
for the information asymmetry or the risk (or the possibility) of
expropr ia t ions agains t minor i ty shareholders . This d ivergence
cou ld influ ence th e owner an d m an agers beha vior which in tu rn
in flu ence th e au dit fee.On the one hand, the divergence could be positively associated
w i t h a u d i t f e e s . T h e a u d i t o r i s p a i d a f e e t o a t t e s t t o t h e

Simmunic 1980). Seetharaman et a l . (2002) f ind that audit fees
reflect r isk differences across countries with different level of
legal liability regime. Higher legal regime motivates the auditors
to increase effort in defense against the increased likelihood offu t u r e lit iga t i on (S im u n ic a n d S t e in 1 9 9 6 ) a n d / o r c h a r ge a n

and Stice 1994). In either case, audit fees should increase if the
divergen ce is r elat ed to th e risk of au dit. We call th is au dit risk
perspective.
On th e other h an d, it is well kn own th at a u dit quality is p riced
in the aud i t marke t (Carce l lo e t a l . 2002 ; Cho i e t a l . 2007b ;

3) Fan an d Wong (2002; 2005) offer a simple exam ple to explain th e case. When
consider ing buying 30% of F i rm B, an en t repreneur has two op t ions . The
entrepreneur can directly buying 30% of equity of Firm B, which constitutes
a typical horizontal corporate stru ctur e, or al terna tively he/ sh e can ind irect ly
invest in Firm B throu gh Firm A, of which h e/ sh e owns 50 %, which h e/ sh e
controls. Choosing the al ternative way, the entrepreneur can purchase the
shares of the Firm B paying only half cost of direct investment, leaving the
saved purchas ing cos t to be borne by the ou ts ide shareholders . Given the
ownersh ip i l lus t ra ted above, i t cos ts the en t repreneur on ly $15 for every
$100 expropriated from Company B and therefore 85$ of net benefi t from
expropriation falls int o the entr epren eu rs h an ds . Clear ly, if stock pyra m ids
or cross-sharehold ings were used to conso l idate con t ro l , they would a lsoresult in the divergence between ownership and control , which exacerbates
the entren chm ent problem of controll ing owners.

Hypothesis Development
Wh en th e con t ro lling sh a reh o lde r is en t r ench ed by h is / h e r
voting power and there is a large separat ion of the voting and
cash flow rights , the credibil i ty of accounting is reduced (Fan
and Wong 2002; Francis et al. 2005; Kim and Yi 2005). Outside
investors pay less at tention to the reported accounting numbers ,
because they expec t tha t the con t ro l l ing owner p roduces and
repor ts account ing informat ion out of pr iva te incent ive ra thert h a n a s a t r u e r e fle c t io n o f t h e fir m s e c o n o m ic s t a t u s . In
add it ion, th e firm s r eported ear nings m ay not b e tru sted b y the
outside investors since they perceive the possible manipulation

cont rolling owner s incen tive to avoid report ing in form at ion t h at
would invite scrutiny from outside shareholders. As a result, the
loss of c redibi l i ty in repor ted earnings lowers the s tock pr ice
informativeness of the earnings (Fan and Wong 2002). Francis et

Expropr ia t ion , i f de tec ted , may induce c lose a t t en t ion and
external intervention by minori ty shareholders , analysts , s tock
exchanges, or regulators. Therefore the desire to keep away from
externa l moni tor ing , potent ia l lega l problems , and consequent
loss of reputation capital likely encourages insiders to veil their

managing repor ted account ing income, espec ia l ly in the weak
legal environment (Haw et al. 2004; Leuz et al. 2003). Because
minor i ty shareholders and other externa l s takeholders a re not
l ikely to have the resources or access to relevant informationenou gh to observe in siders act ions , th ey are, as a r esu lt , u na ble
to detect an d s t raight en ou t ins iders earn in gs m an agement. In
particular, by limiting outflow of information to the public, large
shareholder also allows political rent seekers to evade potential

disc losure and low t ransparency in repor ted income (Fan and

Th ese cha ra cteristics related to th e own ersh ip divergen ce cou ld
b e i n f l u e n c e t h e l e v e l o f a u d i t f e e s . O n t h e o n e h a n d , t h edivergence could be positively associated with audit fees if we
accept th e au dit risk p ersp ective. Th e au ditor is p aid a fee to
a t t e s t t o t h e a s s e r t i on s c on t a i n e d i n t h e c lie n t s f in a n c ia l
s ta temen ts , an d presu m ably th e fee reflects the work th e au ditor
must perform to bear the audit r isk (Choi et a l . 2007a; Craswell
et a l . 1995 ; Sim mu nic 1980). Seeth ara ma n et a l . (2002 ) fin d th at
audit fees reflect risk differences across countries with different
level of legal liability regime. Higher legal regime motivates the
a u d i t o r s t o i n c r e a s e e f fo r t i n d e f e n s e a g a i n s t t h e i n c r e a s e d
likelih ood of fu tu re l it igat ion (Sim u n ic an d Stein 199 6) an d/ or
charge an insurance premium to cover possible future litigation
cos ts (Pra t t and St ice 1994) . In e i ther case , audi t fees should
inc rease i f the d ive rgence i s re la ted to the r i sk o f aud i t . As
e x p la i n e d b e fo r e , b e c a u s e t h e d i ve r g en t f i r m s h a v e le s s

natural logarithm of yearly audit fees paid by a client, as posted
in the DART system. Equation (1) includes a test variable, DVC
which is def ined as the d ivergence be tween vot ing r ights andcash flow rights of a controlling shareholder of a firm. If the audit
r isk perspective dominates , the coefficient on DVC (i.e., a 1) is
expected to have a positive relation with FEE (i.e., a 1 > 0). In

coefficient on DVC (i.e., a 1) is exp ected t o ha ve a n egative relation
with FEE (i.e., a 1 < 0).
The control variables used in equation (1) are chosen based on
the prior studies of Simunic (1980) and Choi et al. (2007a). SIZE
represents firm s ize which is m easu red by th e na tu ral logari thmof th e m ar ket value of comm on s tock. Genera lly, lar ge firm s h ave
greater a ssets to be au dited by externa l au ditors , incu rring more
audit efforts and thus increasing audit fees (Simunic 1980). So,
SIZE is expected to be positively related to FEE (i.e., a 2 > 0). BIG4
cap t u res a u d i to r s s ize e ffec t on au d i t fees . B ig b ran d n am e
auditors are well documented to earn a fee premium over non-
Big audit firms (Craswell et al. 1995; Francis 1984). So BIG4 is
expected to have a positive relation to FEE. ROA a n d LEV is the
proxies for a client-specific audit risk to be borne by auditors.
ROA is introduced because more profi table companies are less
l ike ly to end up in bankrup tcy and so i s expec ted to have a
negative association with FEE. LEV captu res r isk a ssociated with
h ighe r l eve l o f deb t and thus i s expec ted to have a pos i t ive
relation with FEE. To clear the possible effect of outliers, this
variable is f irs t winsorized at the 10 s t a n d t h e 9 0 t h percenti le
valu es. We also includ e th e ra tio of in vent ory an d r eceivab les ou t
of total assets (INVREC) as a proxy for audit complexity, which
in creases a u dit fees . New debt or equ ity issu an ce du mm y (ISS UE)

significan t a t th e 1% level (t = 30.27).
The results using the full model of equation (1) are reported in
the column (2) of table 4. The coefficients on DVC i s -0 .0016
which is significant at the 1% level (t = -3.53), support ing the

power s l ightly increases from 0.752 in column (1) to 0.758 in
column (2). In addition, there are no qualitative differences for
other control variables at all between column (1) and (2). Theseresu lts clearly su ggest th at th e low au dit qu ality effect domin ates
the audit pricing mechanism with respect to the divergence. I t
implies that the firms with greater divergence do not want high-
qua l i ty aud i t s e rv ice , thus a sk aud i to rs to pe r fo rm on ly low-
qu ality au dit service an d p ay au dit fees accordingly.
Controls for the Endogeneity
I t may be possible that the documented results up to table 4could be endogenuous firm characteris t ics that determines both
t h e c o r p o r a t e g o v e r n a n c e m e c h a n i s m a n d a u d i t f e e s . F o r
example , a sma l l - s i zed c l i en t f i rm may have weak corpora te
governance mechanism and also prefer low quality audit service.
In this case, not the corporate governance mechanism but also
the f irm s ize is the main driver of the f indings. To check this
poss ib i l i ty , we adopt 2-s tage regress ion method by us ing the
followin g first st a ge probit r egress ion m odel.
GOODCG = 4.71 79 + 0.26 64 SIZE 1.9 20 8 ROA 0.6 17 8
ISS UE + 0.217 6 LEV + e (2)
In equation (2), a 0 to a 4 are regress ional parameters , e is a
normally dis tr ibuted error term, and GOODCG is th e measu re of
good corporate governance. The variable has a value of 1 if the
DVC is below median value and 0 otherwise. Because there exist
no prior s tudies that examine the determinants of the ownership
d ive rgence , we choose th ree de te rminan t s o f GOODCG (ROA ,
IS S UE, and LEV) through trial and errors. First, we select everycon t ro l employed in equa t ion (1 ) and seve ra l o the r pos s ib le

After adding the inverse Mills ratio calculated using equation

in this s tudy. However, the second s tage regression results do
not change qualitatively at all . For example, if we perform thesame analyses as those repor ted in column (2) of table 4 , the

presu m ably th e fee reflects th e work th e au ditor m u st p erform to
bear the audit risk. Audit fees should increase if the divergence
is related to th e risk of au dit. On th e other h an d, it is well kn own
that audit quality is priced in the audit market. If the divergence
is re la ted to the incent ive for owners to expropr ia te minor i ty
shareholders , i t i s poss ib le tha t the owner asks the audi tor to
prov ide low qua l i ty aud i t s e rv ice in o rde r no t to revea l t rue

emp irical resu lts reveal th at th e au dit fee is n egatively correlated
with the divergence. This finding is somehow inconsistent with
th e fin ding in Fan an d Won gs (200 5) stu dy with other cou n tries
d a t a t h a t h a v e p o s i t i v e a s s o c i a t i o n b e t w e e n q u a l i t y a u d i t o r
choice and the ownership divergence. The difference could be
due to different investor protection and legal system in different
coun t r i e s . Because the l eve l o f inves to r p ro tec t ion i s low inKorea, it is possible that client firms in Korea do care less about
audit r isk but care more about saving audit fee compared with
client firms in the strong investor protection and legal system.
Under the lack of legal risk, auditors also have less incentive to
provide h igh-qu ality au dit ser vice to a void in vestor lawsu its.
The findings in this s tudy are very important because i t can
cont ribu te to regu lators , a cademics , as well as p racti t ioners a n d
in vestors in var iou s ways.
