INTRODUCTION
This study examines the effectiveness of regulatory
changes, specifically the Corporate Law Economic
Reform Program Act 2004 (Cth) (hereafter CLERP 9)
on auditor independence and audit quality
Auditor-provided non-audit services have been one
of the most debated issues for the last several
decades, with arguments that abnormally high fees
for auditor-provided non-audit services may
compromise auditor independence (DeAngelo,
1981; Teng, 2006) Hoitash, Markelevich and
Barragato (2007) argue that any association
between the fees paid to auditors and audit quality
is an important input to the ongoing debate on
how the accounting profession should be organized
and monitored Following prior studies concerned with auditor independence, this study uses auditor-provided non-audit services (NAS) fees and abnormal NAS fees as measures of auditor independence (e.g., Craswell, 1999; DeFond, Raghunandan & Subramanyam, 2002; Frankel, Johnson & Nelson, 2002; Ashbaugh, LaFond & Mayhew, 2003; Chung & Kallapur, 2003; Kinney,
Palmrose & Scholz, 2004; Cahan et al., 2008) and
investigates the extent to which those fees are associated with audit quality in pre- and post-CLERP 9 periods Consistent with prior studies (e.g., Carey & Simnett, 2006; Choi, Kim & Zang, 2006; Chen, Sun & Wu, 2010; Chi, Douthett & Lei, 2010), this study uses the propensity to issue a going-concern opinion for financially distressed companies and the absolute value of discretionary accruals as proxies for audit quality
Corporate governance failures have reduced investor confidence and raised questions regarding the integrity of the information provided to investors (Jain & Rezaee, 2003; Jain, Kim & Rezaee, 2003; Cohen, Dey & Lys, 2005) The highly publicized failures triggered the passage of the Sarbanes Oxley Act (SOX) on 30 July 2002 in the US and the CLERP 9 Act (2004) on 25 June 2004 in Australia Although CLERP 9 introduced sweeping changes, the implications of the reforms are yet
to be ascertained Examination of the impact of the CLERP 9 on NAS fees and their associations with audit quality will provide evidence of the effectiveness of regulatory changes
Effective for the reporting period commencing
on or after 1 July 2004, the CLERP 9 reforms require the mandatory disclosure of specific categories of NAS fees, although the NAS fees have been disclosed in the annual reports for a long period of time for Australian Securities Exchange (ASX) listed companies The Corporations Act 2001 (s300) requires that the audit committee or, in the absence
of an audit committee, the board of directors is required to formally attest to their satisfaction that auditor independence was not compromised by the provision of NAS In annual reports, in accordance with the requirements of s307C of the Corporations Act 2001, the lead audit partner must state that there were: (a) no contraventions of the auditor independence requirements of the Corporations Act 2001; and (b) no contraventions of any applicable code of professional conduct in relation
to the audit CLERP 9 also mandated the rotation
of both the lead and review audit partners every five years due to concerns about the familiarity
Trang 3between the auditor and audit clients and their
effects on auditor independence There is presently
a lack of empirical evidence on the impact of
CLERP 9 on audit quality Therefore, this study
seeks to provide such evidence
The results show a significant and positive
association between NAS fees and the propensity
to issue a going-concern opinion for a financially
distressed company post-CLERP 9, but this
association is not significant pre-CLERP 9 The
results indicate that auditors are more likely to issue
a going-concern opinion for a financially distressed
company post-CLERP 9 The results also show a
significant and negative association between
abnormal NAS fees and the propensity to issue a
going-concern opinion for a financially distressed
company pre-CLERP 9, but this association is not
significant post-CLERP 9 Further, the association
between positive abnormal NAS fees and the
propensity to issue a going-concern opinion for a
financially distressed company is stronger
pre-CLERP 9 than post-pre-CLERP 9 The results indicate
that auditors were less likely to issue a
going-concern opinion for a financially distressed
company pre-CLERP 9 than post-CLERP 9 when
auditors earn abnormally high NAS fees
The association between NAS fees and the
discretionary accruals is significant and positive
pre-CLERP 9, but this relationship is not significant
post-CLERP 9 The results indicate that auditors
tolerated a larger magnitude of accruals when
they earned higher NAS fees pre-CLERP 9, but
that significant association was mitigated by the
introduction of CLERP 9 Furthermore, abnormal
NAS fees are significantly and positively associated
with the absolute value of discretionary accruals
pre-CLERP 9, but this association is not significant
post-CLERP 9 In addition, the association between
positive abnormal NAS fees and the absolute value
of discretionary accruals is stronger pre-CLERP 9 as
compared to post-CLERP 9 Based on the results of
multiple proxies of auditor independence and audit
quality, the results provide evidence of improved
audit quality after the implementation of CLERP 9
The results documented in this study make
significant contributions to the literature Similar
studies have been conducted in the US; however,
the US legislative response (i.e., SOX) is quite
different from that in Australia Thus, the current
paper address the question: Is the Australian
approach effective? This is an important question
for policy making to achieve an outcome with the
least compliance cost This study provides evidence
as to whether there is an observable impact from the CLERP 9 reforms This has not been examined
in prior Australian studies; therefore, the paper provides new evidence on the success of the CLERP 9 approach to addressing problems with audit practice
The remainder of the paper is organized as follows: The next section discusses the background
of the regulatory changes, followed by presentation
of the hypotheses The fourth section describes the research method and provides information about the sample The findings are reported in the fifth section, and this is followed by conclusions in the final section
REGULATORY CHANGES During the last decade, corporate collapses throughout the world have received a great deal
of media attention (Fargher & Jiang, 2006), questioning the adequacy of regulations to improve auditor independence and audit quality Following these corporate failures, the adequacy of the Australian regulations that aimed to ensure auditor independence were questioned, which resulted in a review of the independence of Australian company auditors (Fargher & Jiang, 2006) This review resulted in the publication of the Ramsay Report
in October 2001 (Ramsay, 2001), and subsequently the CLERP 9 draft was proposed in September
2002 In the US, corporate legislation, SOX (2002), was passed in response to a series of financial scandals (Chambers & Payne, 2008) The debates in the Ramsay Report (2001) and the CLERP 9 proposal focused on the joint provision of audit and non-audit services (Fargher & Jiang, 2006) To improve auditor independence and audit quality in the joint provision of audit and non-audit services, the Joint Committee of Public Accounts and Audits (JCPAA, 2002) and the ASX Corporate Governance Council issued reports on best practice guidelines for listed companies (ASX, 2003) Australian reporting entities adopted Australian equivalents
of International Financial Reporting Standards (IFRS) for the reporting period commencing on or after 1 January 2005 In annual reports, in accordance with the requirements of s307C of the Corporations Act 2001, the lead audit partner has
to declare whether there are: (a) any contraventions
of the auditor independence requirements of the Corporations Act 2001; and (b) any contraventions
Trang 4of any applicable code of professional conduct in
relation to the audit
CLERP 9 does not ban any particular NAS
provided by the auditor However, this Act stresses
that the auditor must identify and evaluate threats to
independence and apply safeguards to reduce any
threats to an acceptable level (Ramsay, 2001) Where
the provision of NAS to a client poses a threat that
cannot be reduced to an acceptable level, CLERP 9
prohibits the provision of that service (Ramsay,
2001) As part of the CLERP 9 reforms, the
Corporation Act 2001 was amended to require the
mandatory disclosure of fees paid for the specific
categories of NAS provided in companies’ annual
reports for the reporting period commencing on or
after 1 July 2004 Moreover, the reforms stipulated
that the financial statements must include a
statement by the audit committee (or board in its
absence) that it is satisfied that the provision of
NAS is compatible with auditor independence
(Corporation Act 2001, s300) This disclosure should
include an explanation of why certain problematic
NAS, such as IT systems services and internal audit
services, if contracted, did not compromise auditor
independence (CLERP 9, 2004)
Regulators and legislators throughout the world
apparently presume that providing NAS impairs
auditor independence, which may lead to lower
audit quality (Kinney et al., 2004) After the
implementation of SOX (2002), most NAS were
banned in the US, and SOX also requires prior
approval by a registrant’s independent audit
committee of any NAS allowed by law (Kinney
et al., 2004) Using pre- and-post SOX data, prior
studies (e.g., Hoitash et al., 2007; Li, 2009) find a
significant association between NAS fees and audit
quality during the pre-SOX period and the
association is not significant post-SOX In
Australia, CLERP 9 has not banned NAS; however,
both the auditors and the audit committee
(or board in its absence), must declare that
the provision of NAS has not compromised
auditor independence Therefore, the objective
of the current study is to investigate whether
the implementation of CLERP 9 mitigates the
association between NAS fees and audit quality
DEVELOPMENT OF HYPOTHESES
Association between auditor-provided NAS
fees and audit quality
The objective of passing CLERP 9 was to improve
auditor independence and audit quality CLERP 9
and the Corporations Act 2001 require auditors to sign a declaration in the annual report stating that the independence of the auditor has not been compromised due to NAS The audit committee (or board in its absence) must also declare that the external auditor is working without impaired independence CLERP 9 does not prohibit
mandates disclosure of the types of NAS fees in the annual report It is expected that non-audit fees will decrease due to the additional auditing pronouncements and disclosure of types of NAS and the prospect of greater regulatory reporting requirements by companies following those legislative reforms In addition, after the implementation of SOX in 2002, most NAS fees were banned in the US Big 4 audit firms applying the international ruling can have the same effect in Australia because Big 4 audit firms are international audit firms and may apply the same policy in auditing their Australian clients
Auditor provided non-audit services have long been regarded as a threat to auditor independence
by the regulators both in Australia and overseas (Craswell, 1999) Investigating the effect of the
legal and regulatory changes in China, Chen et al.
(2010) find a negative association between client importance at the audit partner level and modified opinions during the pre-regulatory change period and a positive association during the post-regulatory change period The findings of Chen
et al (2010, p 127) suggest that ‘institutional
improvements prompt auditors to prioritize the cost of compromising quality over economic benefits gained from important clients.’ Reynolds and Francis (2001) find that client importance is positively associated with the issuance of going concern reports for Big N clients Craswell, Stokes and Laughton (2002) argue that if fee dependence affects auditors’ independent judgements, then auditors are less likely to issue qualified audit opinions Using Australian data, Craswell (1999) reports that auditors’ decisions to qualify audit opinions are not affected by the provision of non-audit services Other Australian studies (e.g., Wines, 1994) find a significant and negative association between NAS and qualified opinions and argue that NAS creates perceptions of independence problems In contrast, Barkess and Simnett (1994) do not find a significant association between NAS and qualified opinions Using US data, Li (2009) finds that client importance is not significantly associated with the issuance of
Trang 5going-concern opinions during the pre-SOX
period, but that there is a positive association
post-SOX Based on the prior discussion, I expect a
significant positive association between NAS fees
and the propensity to issue going-concern opinions
pre-CLERP 9 and no or a significant negative
association post-CLERP 9 Thus, I propose the
following hypothesis:
H1a:There is a positive association between NAS fees
and the propensity to issue a going-concern opinion
for a financially distressed company post-CLERP 9
but not pre-CLERP 9.
Regulators and legislators apparently presume
that auditor-provided non-audit services impair
auditor independence, which leads to lower quality
audits (Kinney et al., 2004) The findings of prior
studies regarding the associations between NAS
fees and earnings management-based audit
quality measures are mixed Frankel et al (2002)
hypothesized that NAS increases the economic
bonding between auditors and clients and
therefore impairs auditor independence Cahan
et al (2008) argue that faster growth and longer
time period over which non-audit services are
purchased from auditors may reduce auditor’s
independence However, they did not find any
support of a relationship between fee growth rates
and length of purchasing non-audit services and
discretionary accruals Studies by Krishnan, Sami
and Zhang (2005) and Francis and Ke (2006) find
lower earnings response coefficients for firms
paying higher NAS fees Ferguson, Seow and
Young (2004) find that client importance is
positively associated with the absolute value of
abnormal accruals Ghosh, Kallapur and Moon
(2009) find that client importance is negatively
associated with earnings response coefficients
Using pre- and-post SOX data, Hoitash et al (2007)
find a significant and positive association between
NAS fees and discretionary accruals pre-SOX and
no significant association post-SOX
In contrast, Reynolds and Francis (2001) find that
client importance is negatively associated with the
absolute value of abnormal accruals The intention
of regulatory changes is to improve the quality of
financial statement audits and audit quality, which
will also influence earnings reliability (Chambers
& Payne, 2008) In Australia, effective after 1 July
2006, lead audit partner rotation was mandated
(Fargher & Jiang, 2008), and this new mechanism of
mandating audit partner rotation has given audit
standards legislative backing (Carey & Simnett,
2006) The reforms also included proportionate liability for auditors and claims capping, which provided auditors with some certainty on liability claims (Fargher & Jiang, 2008) This could well affect auditor behaviour regarding earnings quality measures As reduced earnings management is used as one of the indicators of improved audit quality (Wong, Jubb & Chalmers, 2007) vis-à-vis
financial reporting quality (see Becker et al., 1998)
and audit quality is affected by independence, it follows that if the implementation of CLERP 9 increased auditor independence, it may have consequently improved earnings management-based measures of financial reporting quality Therefore, I expect a significant positive association between NAS fees and the absolute value of performance-adjusted discretionary accruals pre-CLERP 9 and no or a significant negative association post-CLERP 9 Thus, I propose the following hypothesis:
H1b: There is a positive association between NAS fees and the absolute value of discretionary accruals pre-CLERP 9 but not post-CLERP 9.
Association between abnormal NAS fees and audit quality
The objectivity and independence of auditors is more likely to be influenced by the level of client fees in excess of the auditor’s expectation of normal fees, i.e., abnormal fees, rather than expected fees
(Choi et al., 2006) Choi et al (2006) argue that when
an auditor earns more than the expected level of NAS fees, the perceived net benefits become greater than the associated costs, which increases economic bonding and may decrease audit quality Kinney and Libby (2002) argue that strong economic bonding between the auditor and the client will reduce the quality of the reported earnings through the auditor’s reduced willingness
to resist client-induced biases in reported accounting information Auditors may also be reluctant to issue a going-concern opinion due to the possibility of losing the client Using pre- and
post-SOX data, Hoitash et al (2007) find a
significant positive association between abnormal NAS fees and accruals pre-SOX and no significant
association post-SOX Hoitash et al (2007) provide
evidence consistent with the view that clients with higher abnormal NAS fees may have more influence on auditors’ decisions that lead to
impaired auditor independence Choi et al (2006)
Trang 6suggest that auditors’ incentives to compromise
audit quality differ depending on whether the
client pays more than or less than the normal level
of fees, which, in turn, leads to the audit fee–audit
quality association being based on the sign of
abnormal audit fees Thus, I propose the following
hypotheses:
H2a: There is a negative association between
abnormal NAS fees and the propensity to issue a
going-concern opinion for a financially distressed
company pre-CLERP 9 but not post-CLERP 9.
H2b: There is a positive association between
abnormal NAS fees and the absolute value of
discretionary accruals pre-CLERP 9 but not
post-CLERP 9.
RESEARCH METHOD
Measurement of abnormal NAS fees
Following the procedures of Choi et al (2006) and
Hoitash et al (2007) of decomposing fees into two
components, namely the expected component
(normal fees) and the abnormal component
(abnormal fees), it is necessary to specify an
expectation model linking actual fees with their
determinants On the basis of economic bonds,
client size, client complexity and client-specific
risk from prior studies (e.g Simunic, 1980;
Francis & Stokes, 1986; Craswell et al., 1995;
DeFond et al., 2002; Frankel et al., 2002; Whisenant
et al., 2003; Choi et al., 2006; Hay et al., 2006) and
independence measures reported by Ashbaugh
et al (2003) and Ruddock, Taylor and Taylor
(2006), this study uses the following ordinary
least squares (OLS) model to calculate abnormal
NAS fees for each year separately The abnormal
NAS fees are the residuals of the estimated
model:
LnNAS LnTA BIG EQUITY
MERGACQS ROA LEVERAG

LnSUBS FOROPS USLIST

where
LnNAS = natural log of auditor-provided non-audit
services fees;1
Control variables
LnTA = natural log of total assets;
BIG4 = 1 if the audit firm is a Big 4 firm, 0 otherwise;
EQUITY = 1 if the company issued new shares in the current year, 0 otherwise;
MERGACQS = 1 if the company has merger or acquisition activities during the current year, 0 otherwise;
ROA = earnings before interest and taxes divided
by total assets;
LEVERAGE = total liabilities divided by total assets;
NEG_ROA = 1 if the company reports a negative return on assets in the current year, 0 otherwise; GROWTH = change of assets from prior year;
MB = market-to-book value;
LnSUBS = natural log of number of subsidiaries; FOROPS = 1 if the company has any foreign subsidiaries, 0 otherwise;
USLIST = 1 if the company is cross-listed in the US,
0 otherwise;
∑INDUSTRY = there are 10 indicator variables for
11 Global Industry Classification Standard (GICS) industry groups
Definitions of the variables are provided in the Appendix for ease of reference The natural log of total assets (LnTA) is used as a proxy for client size Demand for non-audit services is likely to increase
with firm size (Palmrose, 1986; Raghunandan et al.,
2003) and, therefore, it is expected that NAS fees are positively associated with LnTA Non-audit services fees are likely to be higher for clients with more complex business operations (Raghunandan
et al., 2003) LnSUBS, MERGACQS and FOROPS
are used to proxy for client complexity, and it is expected that the variables representing client complexity are positively associated with NAS fees NEG_ROA, LEVERAGE and ROA are used to proxy for a client’s risk characteristics Since an auditor charges higher fees for riskier clients (Simunic & Stein, 1996), the coefficients of NEG_ROA and LEVERAGE are expected to be positive and that of ROA to be negative The control variable, BIG4, is used to capture the capacity of providing non-audit services and a positive coefficient is expected with NAS fees The demand for non-audit services is greater for high-growth firms than low-growth firms (Choi & Wong, 2006) EQUITY, GROWTH and MB are used
to capture the effect of a client firm’s growth on NAS fees, and positive associations with fees for EQUITY, GROWTH and a negative association
Trang 7with MB are expected A control variable for the
US cross-listing (USLIST) is used owing to the
additional requirements in US regulations Similar
to Ashbaugh et al (2003) and Ruddock et al (2006),
this study uses industry dummies to control for
cross-industry differences in fees INDUSTRY is an
indicator variable equal to 1 if the company belongs
to an appropriate industry group, 0 otherwise
Audit opinion model
The following logistic regression model is
estimated for the pre- and-post-CLERP 9 periods to
test the association between NAS fees, abnormal
NAS fees and the propensity to issue a
going-concern opinion for a financially distressed
company after controlling for the variables used by
Carey and Simnett (2006):
OPINION LnFEE PQUAL PBANK

Dependent variable
OPINION = OPINION is coded as 1 if an auditor
issues a going-concern opinion for a financially
distressed company in the current year and as 0
otherwise;
Experimental variable
FEE = alternative measures of fees, such as: LnNAS
is the natural log of auditor-provided non-audit
services fees;2ABNAS fees are estimated from the
residuals of the LnNAS fee model (Equation 1);
Control variables
PQUAL = 1 if the auditor issued an opinion other
than an unqualified one in the previous year, 0
otherwise;
PBANK = probability of bankruptcy, as measured
by adjusted Zmijeswki score;3
LnAGE = natural log of number of years the
company has been listed on the Australian
Securities Exchange (ASX);
CLEVERAGE = change in leverage during the year;
LLOSS = 1 if the client reported a loss in the
previous year, 0 otherwise;
INVESTMENTS = short- and long-term investment
securities (measured as current assets minus
debtors and inventory) divided by total assets;
CFO =operating cash flow deflated by total assets;
MINING = 1 if the company belongs to the mining industry, 0 otherwise;
e = error term
All other variables are as defined in Equation (1) Prior year opinion (PQUAL) is a good predictor
of the current year’s opinion because the going-concern problems may continue for a longer period (Monroe & Teh, 1993) Higher values of
bankruptcy (Carey & Simnett, 2006) LnTA is included because larger companies are less likely
to end up in bankruptcy, due to their financial stability and greater negotiating power (Carey & Simnett, 2006) LnAGE is controlled because younger companies are more likely to encounter financial distress (Carey & Simnett, 2006) Similar
to Carey and Simnett (2006), I use LEVERAGE and CLEVERAGE to control for the risk of insolvency ROA and LLOSS capture the profitability of the companies, as companies incurring a loss are more likely to receive a going-concern opinion (Carey & Simnett, 2006) CFO and INVESTMENTS proxy for the liquidity risk of a company, and a liquidity crisis may end in bankruptcy (Carey & Simnett, 2006) BIG4 is included in order to differentiate the propensity of issuing going-concern opinions
by Big 4 and non-Big 4 audit firms MINING is controlled because the sample includes a large number of mining companies, which have different financial characteristics (Butterworth & Houghton, 1995; Carey & Simnett, 2006)
Earnings management model
Similar to Kothari, Leone and Wasley (2005), this study estimates non-discretionary accruals using the performance-adjusted modified Jones (1991) model, and estimates abnormal accruals as the residuals from the model Subject to a minimum of
10 observations (excluding financial sector 40) in each industry category for each year, this model is estimated cross-sectionally for each two-digit GICS (a six-digit for the Metals & Mining sector) industry group in each of the years 2002–2007 as follows:
PPE LagROA
α β
β2 1 β3 ε
where TACC = total accruals, being the difference between operating income (OI) and cash flow from operations;
DREV = change in revenues from period t - 1 to period t;
Trang 8DREC = change in accounts receivables from period
t - 1 to period t;
PPE = gross value of property, plants and
equipment;
LagROA = one-year lag of ROA;
e = error terms
All variables, including the intercept (other than
LagROA), are scaled by the lagged total assets
The model for examining the
association between test variables and
earnings management
This study uses the following model to examine the
association between NAS fees, abnormal NAS fees
and the absolute value of performance-adjusted
discretionary accruals for the pre- and post-CLERP
9 periods after controlling for the variables used in
Carey and Simnett (2006):

residuals of the LnNAS fee model;
Control variables
OPINION = 1 if the company has a modified
opinion during the current year, 0 otherwise;
All other variables are defined in Equations (1) and
(2)
Consistent with the arguments of Carey and
Simnett (2006), a number of variables (BIG4,
PBANK, OPINION, LnTA, LEVERAGE, LLOSS,
ROA, LnAGE, CFO, MINING) used in predicting
the propensity to issue a going-concern opinion are
expected to be associated with the level of
discretionary accruals GROWTH is controlled for
changes in a company’s financial position and their
association with discretionary accruals
Sample selection
CLERP 9 (2004) was enacted on 30 June 2004
Hence, the first reflection of CLERP 9 is seen in
the annual reports prepared for the financial period 2004–05 Therefore, this study uses data from 2002, 2003, 2004 and balance dates between 1 January and 29 June 2005 for the pre-CLERP 9 and 2005 (balance date on 30 June), 2006 and 2007 for the post-CLERP 9 Data were collected up to
2007 because of the Global Financial Crisis in
2008, which might affect the results The initial sample consists of 9,736 firm-year observations whose financial data were available in Aspect’s FinAnalysis database for fiscal years from 2002 to
2007 NAS fees and audit opinions data were hand-collected directly from the annual reports Consistent with Carey and Simnett (2006), the sample for the audit opinion model is restricted
to financially distressed companies only I identified financially distressed companies based
on either the company reporting a loss or a negative cash flow from operations during a given year The sample size is further reduced because of data requirements for predicting the type of audit opinions The final sample consists
of 4,961 firm-year observations for the OPINION model
The sample of discretionary accruals models was derived after excluding financial sector (GICS 40) and data requirements for estimating discretionary accruals The final sample is 6,656 firm-year observations for the DACC model Table 1 shows how the sample sizes are derived for this study Table 2 shows the industry representation of the sample companies The current study uses a two-digit GICS code (a six-two-digit code for Metals & Mining) There are 11 industry groups Similar to prior studies (e.g., Coulton, Taylor & Taylor, 2005), the current study also excludes industry groups for a particular year if the group has fewer than
10 companies when estimating discretionary accruals

Table 3 shows the descriptive statistics for the
sample The average size of the sample companies
post-CLERP 9 the average size was $1,142.609
million and the difference is significant The
average NAS fees are higher pre-CLERP 9
($128,812.616) than post-CLERP 9 ($67,502.291)
and the difference is significant Other than LLOSS
and PQAUL, mean differences for all the control
variables are significantly different between the
pre-CLERP 9 and the post-CLERP 9 periods The
maximum VIF value is 2.708, indicating that
multicollinearity is not a significant concern
Association between NAS fees and OPINION
Table 4 provides the logistic regression results for
the association between NAS fees and the
propensity to issue a going-concern opinion for a
financially distressed company during the pre- and
post-CLERP 9 Consistent with Carey and Simnett
(2006), the sample is restricted to financially
distressed companies The model is well-fitted with
pseudo R2s ranging from 0.239 to 0.252 The results
(Table 4, columns 2 and 3) show that the association
between the LnNAS fees and the propensity to
issue a going-concern opinion for a financially
distressed company is significant and positive
post-CLERP 9 (coefficient = 0.049, p = 0.006)
(one-tailed) and is not significant pre-CLERP 9 (coefficient = -0.021, p = 0.104). The findings indicate that auditors are more likely to issue a going-concern opinion for a financially distressed company post-CLERP 9 when providing NAS fees This finding is consistent with the US study
by Li (2009), who finds that client importance is not significantly associated with the issuance
of going-concern opinions pre-SOX, but that association is significant and positive post-SOX The significant association between LnNAS fees indicates the improvement of auditor independence and audit quality post-CLERP 9 Auditors earning more than the expected level of NAS fees may compromise audit quality
To test whether the association between abnormal
going-concern opinions remained the same before and after the implementation of CLERP 9, this study estimated abnormal NAS fees based on the NAS fee model (Equation 1) Table 4 (columns
4 and 5) shows that the association between the signed abnormal NAS fees is significantly and negatively associated (coefficient = -0.036,
p = 0.005) with OPINION pre-CLERP 9, but is not significant (coefficient = 0.017, p = 0.196)
post-CLERP 9 A separate analysis (not tabulated) shows that the association between positive abnormal NAS fees and OPINION is significant
and negative (coefficient = -0.090, p = 0.003) and
stronger pre-CLERP 9 than post-CLERP 9
(coefficient = -0.173, p = 0.040) These findings also
indicate that auditor independence and audit
