Abstract: This research aims to analyze the association between the related-party 
transactions and audit fees. This study used 781 observations listed on the Indonesia Stock 

Exchange from 2010 to 2017. The analysis technique used in this research was the 

Ordinary Least Square Regression analysis model processed with STATA 14.0 software.  

This study found that related-party transactions are positively and significantly related to 

audit fees. The result indicated that the related-party transactions increase audit fees paid 

by companies. It also investigated the moderating effect of industry specialty auditors. 

This indicated that auditor specialization strengthened the relationship between the 

related-party transactions and audit fees. The market share proxy was used to measure 

industry specialization. However, this proxy still has disadvantages as it can generate 

different market shares. This study found that related-party transactions increased audit 

fees. The results of this study can be used as consideration in making decisions for related 

parties.

INTRODUCTION 

The existence of related-party transactions related to fraud scandals in accounting practices 

recently raised concerns about current auditing practices (Gordon et al., 2007). The related-party 

transactions need a major concern. In the case of Enron and Adelphia, transactions with related parties 

might be for fraudulent purposes rather than for business purposes and were not adequately disclosed in 

the financial statements (Gordon et al., 2007). Related-party transactions are transactions between 

companies and individuals or organizations related to the companies, such as managers, directors, major 

shareholders, and affiliates (Al-Dhamari et al., 2018; Bona-Sánchez, et al. 2017; Gordon et al., 2007). 

There are various types of related-party transactions, including purchases, sales, loans, or providing loans 

to parties related to the company (Bryan & Mason, 2017; Gallery et al., 2008). Since 2007, research on 

the related-party transactions has increased due to accounting irregularities. Research and practice show 

that the auditing of related-party transactions is problematic. For example, the American Institute of 

Certified Public Accountants (AICPA) admits that related-party transactions are difficult to audit. This is

supported by empirical evidence stating that related-party transactions are one of the top ten audit 

deficiencies often identified in the Securities and Exchange Commission (SEC) Law Enforcement 

Commission (Beasley et al., 2000). The related-party transactions are complex since they involve several 

parties and operations (Kohlbeck & Mayhew, 2017). The factors that determine the amount of payment 

for the audit services provided are the size, complexity, and level of risk of the client's business (Chen et 

al., 2017; Hong & Hwang, 2018; McMeeking et al., 2006; Salehi et al., 2018; Waresul Karim & Moizer, 

1996).   

The emergence of International Standard Auditing (ISA) 550 regarding related parties shows that all 

related parties have a significant risk to the company's financial reporting so it is also risky if the auditor 

audits companies that conduct related-party transactions. The risk faced by the auditor is the possibility of 

an error in providing an opinion on the audit of the financial statements of companies that conduct 

related-party transactions to manipulate financial statements (El-Helaly, 2018).  

Several studies regarding related-party transactions were conducted because they were considered to 

influence the determination of audit fees. Al-Dhamari et al., (2018) show that companies that conduct 

related-party transactions have higher audit fees compared to companies whose related-party transactions 

are few or even nonexistent. However, the results of research conducted by Kohlbeck dan Mayhew 

(2017) said that related-party transactions affect the level of financial report restatement, and audit fees at 

the company are lower. 

In Indonesia, to ensure that an entity's financial statements contain the necessary disclosures to bring 

attention to the possibility that the financial position and profit and loss have been affected by the 

existence of related parties, the Financial Accounting Standards Board (DSAK) issued a Statement of 

Financial Accounting Standards (PSAK) 7 which regulates regarding related-party disclosure. The 

emergence of PSAK 7 provides a signal that related-party transactions may pose a risk to the presentation 

of financial statements. Research conducted by Simunic (1980) shows that the things that affect the 

amount of the audit fees are the size of the client company, audit complexity, and audit risk. Therefore, 

the increase in audit risk is also in line with the increase in fees for audit services. Jiang dan Son (2015) 

argued that the auditor may respond to increased client risk by charging a premium as insurance against 

potential litigation and as an excess effort by the auditor in conducting the audit. If the auditor considers 

that related-party transactions are risky as it will affect the determination of the audit fees because the 

auditor needs more audit effort to ensure that such related-party transactions will not mislead users of 

financial statements. 

Habib dan Bhuiyan (2011) said one of the dimensions of audit quality that differentiates high-quality 

auditors from their lower-quality peers is the degree of specialization of the audit firm's industry. Much 

research has been done on the relationship between industry specialty auditors and audit fees, but no one 

has yet researched the effects of industry specialty auditor moderation on the relationship between 

related-party transactions and audit fees. So, this relationship needs to be studied more deeply. 

Researchers suspect that related-party transactions will positively affect audit costs and the relationship 

between the two is strengthened if the auditors conducting the audit are auditors with industry specialties. 

The industry specialty audit is an industry-specific knowledge that auditing firms use to help auditors 

better understand what clients are doing in a particular industry and the risks they face (Fleming et al., 

2014; Kend, 2008). In addition to discussing the relationship between related-party transactions and audit 

fees, this study will also discuss the relationship between auditors and industry specialties that carry out 

audits of the financial statements of companies conducting the related-party transactions and their impact 

on audit costs. Research related to the related-party transactions is an interesting matter to be studied in 

more depth because related-party transactions pose a significant risk to the company's financial reporting. 

After all, the nature of the transactions is difficult to identify. This causes the audit risk on the related-

party transactions to increase and will affect the amount of audit fees to be paid to the auditors.  

Industry specialty auditor is expected to strengthen the relationship between the two variables 

because auditors with industry specialization have more adequate knowledge of a particular company 

industry so that they will better understand the nature of the company's transactions. The ability of

auditors to identify the things mentioned above will increase the amount of audit fees so that companies 

that carry out related-party transactions whose financial statements are audited by auditors with industry 

specializations will have a higher audit fee. So it is assumed that related-party transactions affect the 

amount of audit fees paid by the company and if the company is audited by auditors with industry 

specialties, the relationship between the two will be stronger. 

This research can contribute to the literature related to related-party transactions which can then be 

used for the development of further studies in accounting. First, this study provides an understanding of 

why related-party transactions affect the amount of audit fees. Second, this study provides an 

understanding that those companies that are audited by industry specialization auditors will pay higher 

audit fees. Also, the results of this study are expected to be useful as a consideration in making decisions 

regarding the related-party transactions. 
 

LITERATURE REVIEW AND HYPOTHESES  

Related-party Transactions and Audit Fees 

According to Ryngaert dan Thomas (2012), a related-party transaction is an efficient contract 

mechanism when there is incomplete information. A related-party transaction can be used as a tool to 

transfer resources to related parties (Aharony et al., 2010; Johnson et al., 2005). According to Gordon et 

al., (2007), there are several reasons why it is difficult to audit related-party transactions, besides it is 

difficult to identify related-party transactions, the auditor also relies heavily on information provided 

about related parties and related-party transactions.   

PSAK 7 states that disclosures related to related parties are necessary for presenting financial 

statements because the statements of financial position and profit and loss, as well as transactions and 

balances, are affected by the existence and commitment of related parties or so-called related parties. 

According to PSAK 7, a related party is a person or entity that is related to a certain entity in preparing its 

financial statements. PSAK 7 regulates what matters need to be disclosed in the financial statements, for 

example, in the entity's relationship with related parties, compensation given to key management, and 

related-party transactions. 

Indonesia has also regulated the amount of audit fees that must be paid to public accountants with 

the consideration that an audit fee for auditing financial statements that is too low can pose a threat in the 

form of personal interests which has the potential to cause non-compliance with the professional code of 

ethics of the Public Accountant. Therefore, the Indonesian Institute of Public Accountants (IAPI) issued 

PP No. 2 of 2016 concerning the determination of fees for financial statement audit services. IAPI also 

regulates the indicator for the lower limit of audit service billing rates. This is done so that in conducting 

audits, auditors remain obedient to the code of ethics of the Public Accountants and applicable 

regulations. The determination of the lower limit in determining the service fee is expected so that the 

entire service fee is adequate for the auditor to perform audit procedures. The amount of the audit fee (fee 

for services) is the result of calculating the number of hours worked multiplied by the value of the hourly 

audit fee. In PP No. 2 of 2016, IAPI requires auditors to calculate the amount of time required for each 

stage of the audit which consists of risk assessment, risk response, and reporting. This is done so that the 

auditor can calculate the service fees that must be paid by the company for financial statement audit 

services. 

Things that affect the amount of the audit fees are the size of the client company, the complexity of 

the audit, and the audit risk (Simunic, 1980). Audit risk consists of three, namely inherent risk, control 

risk, and detection risk. The research conducted by Jiang dan Son (2015) shows the results that the auditor 

responds to the presence of control risk, the auditor will charge a fee that is higher than the cost of 

carrying out the audit. The related-party transactions are very important for the auditor because there will 

always be risks that are judged to be different if the transactions are made with third parties (Al-Dhamari 

et al., 2018). One of the risks of related-party transactions is a decrease in the level of independence 

between parties, thus violating the arm's length principle.

There is a significant and positive effect of related-party transactions on audit fees (Al-Dhamari et 

al., 2018). This is because the auditor considers that related-party transactions increase audit risk. If the 

auditor assesses that there is a potential risk, the auditor will charge a higher fee as compensation for the 

risk and effort that must be made to describe the transaction and provide assurance that related-party 

transaction does not provide misleading value.  

 

H1: There is a positive relationship between the related-party transactions and audit fees. 

 

Industry Specialty Auditor and Audit Fees in Companies Conducting Related-party Transactions 

Having in-depth knowledge of an industry means understanding the economy of the industry, key 

accounting policy issues, specific industry issues, and its business practices. (Kend, 2008; Nagy, 2014). 

Understanding the client industry increases the professional auditor's skepticism about the appropriate 

recognition and judgment of transactions and events related to the industry (Scott & Gist, 2013; Solomon 

et al., 1999). A deep understanding of a particular industry will increase the effectiveness and efficiency 

in conducting audits. A specialist's knowledge of an industry is built up through extensive audit 

experience, specialized staff training, and expensive investment in information technology  (DeBoskey & 

Jiang, 2012). 

The results of research conducted by Fuentes dan Sierra (2015) shows that industry-specialized 

auditors influence determining the amount of audit fees. The auditor's industry specialization is one of the 

attributes of audit quality because it increases the likelihood of identifying material misstatements in 

financial statements (Fuentes & Sierra, 2015). In this study, industry-specialized auditors are used to 

seeing whether industry-specialized auditors will influence the audit fees for companies that transact with 

related parties. If companies that carry out many transactions with related parties are audited by auditors 

with industry specialties, it will improve the quality of the financial statements because auditors with 

industry specializations are considered capable of detecting errors, both errors and intentional errors. Bae 

et al. (2016) said that the amount of audit fees associated with industry specialty auditors is a reflection of 

the number of audit services provided by auditors or the result of hourly costs of industry specialty 

auditors, or perhaps the result of both.  

Auditors with industry specialties have in-depth knowledge of industry. Therefore, they will pay 

more attention to transactions and events in the company, especially if these transactions or events present 

the risk of material misstatement in the financial statements. However, in Indonesia, there are no detailed 

regulations that discuss the specialty of the auditor industry and have not determined the lowest level of 

auditors to understand the client industry before accepting an offer to audit the company's financial 

statements. 

 

H2: Audit fees will increase for companies conducting related-party transactions when their financial 

statements are audited by industry specialty auditors. 

 
METHODS  

The approach used in this research is quantitative. This research is conducted to determine the 

relationship between two variables so that this research is included in the associative research group. This 

study examines the effect of the related-party transactions and industry specialty auditors on audit fees. 

All data is secondary data from OSIRIS and data related to auditors comes from the IDX. 

The population used in this study was all companies registered in the IDX for 2010-2017 period, 

consisting of 3,038 companies. The sample selection of this study used a purposive sampling approach 

with predetermined criteria. These criteria are (1) non-financial companies listed on the IDX in the 2010-

2017 period and (2) companies whose annual reports and audited financial reports contain the data 

required for this research. The researcher removes all populations that do not have the required data. 

Researchers only use data from non-financial companies, so researchers delete companies with SIC code 

6. The number of observations in this study is 781 companies.

The measurement of related-party transactions uses the measurement used by Habib et al., (2015). 

The related-party transactions are the result of the natural logarithm of all related-party transactions. 

Besides, researchers measured industry specialty auditors using proxies that already existed in previous 

studies. Industry specialty auditors are measured by the audit company market share which is calculated 

from the total assets of the company being audited by the auditor (Rusmin and Evans, 2017). Then the 

dummy variable of industry specialty auditors is determined, which is given a value of 1 if the auditor's 

market share is the highest and the value of 0 is vice versa. This variable will be interacted with the 

related-party transactions variable to see whether being audited by a specialist auditor will affect the audit 

costs. Audit costs are measured by the natural logarithm of the audit fees paid to the auditor. Researchers 

also use control variables taken from several previous studies regarding audit costs.  

There are two regression models in this study. Model 1 is used to test hypothesis 1, while model 2 

is used to test hypothesis 2. The regression models used are as follows:  

Model 1: 
                                                                                         

                                                                            
               

Model 2: 
                                                                                    

                                                                             
                                       

 

Where audit fee is the natural logarithm of the audit fee. Lnrpt is the natural logarithm of all related 

party transactions. The specialist is a dummy variable where 1 is industry specialty auditors and 0 is the 

opposite. Big4 is a dummy variable where 1 is the auditor included in BIG4 while 0 is the opposite. 

Auditor change is a dummy variable where 1 is for companies whose auditors are different from the 

previous year and 0 is the opposite. The comsize is the number of commissioners in a company. Firmage 

is the company's age since its establishment until 2017. The clientsize is the natural logarithm of total 

assets. Cash is the natural logarithm of cash. Leverage is total debt divided by total assets. Liquidity is 

short-term debt divided by current assets. 

 
RESULTS AND DISCUSSION 

Descriptive Statistics 

Before doing descriptive statistics, winsorize data was conducted first. The winsorize is done to 

overcome data containing outliers by pulling the lowest outliers data to the 1% level and pulling the 

highest outliers data to the 99% level. Table 1 shows the results that the average audit fee value is 

1,913,000,000 and has a median value of 790,000,000. The maximum value of the audit fee is 

36,000,000,000, while the minimum value is 80,000,000. Related-party transactions (LNRPT) have an 

average value of related-party transactions of 540,500,000,000 and a median value of 67,820,000,000. 

The maximum value of this variable is 9,942,000,000 where the transaction is carried out by PT Waskita 

Karya and the minimum value of this variable is 0. 

As additional information, table 2 contains the percentage of companies that disclose audit fees in 

their financial statements based on industry information regarding the type of industry based on SIC. 

Manufacturing and service industries are divided into 2 based on their main characteristics. 

Manufacturing (1) is a company that is included in SIC 2 and manufacturing (2) is included in SIC 3. A 

company with SIC 7 is included in Services (1) and SIC 8 into Services (2). Based on table 2, the 

companies that disclosed the most audit fees were companies engaged in the agriculture, forestry, and 

fisheries industries, which amounted to 39.8%, while the companies that disclosed the least audit fees 

were companies engaged in the service industry, namely 13.8%.

Pearson Correlation 

Based on the results of the Pearson correlation test in Table 3, it can be seen that the related-party 

transactions have a positive relationship with a significance level of 1% on the audit fee. This means that 

the related-party transaction in a company become the auditor's consideration in determining the amount of 

the audit fee. Also, auditors for industry specialization show a positive relationship direction with a 

significance level of 1% with audit fees. This suggests that auditors with industry specialization charge a 

higher audit fees.

Regression in this study was carried out twice, the first is multiple linear regressions by controlling 

the fixed-year effect and the industry-year effect, while the second is performing multiple linear regression 

with robust. As presented in table 5, in the first column multiple linear regressions is carried out for model 

1 and produces an LNRPT coefficient of 0.009 and a t-value of 2.52 with a significance level of 0.05. This 

means that for every 1 point increase in LNRPT, the audit fee will increase by 0.009. In the second column, 

multiple linear regressions is performed robustly and produces an LNRPT coefficient of 0.009 and a t-value 

of 2.76 with a significance level of 0.01. This means that for every 1 point increase in LNRPT, the audit fee 

will increase by 0.009. Both regression results indicate that the related-party transactions positively affect 

the amount of audit fees charged by auditors. So it can be concluded that hypothesis 1 is accepted.

The researcher also conducted tests to determine how the relationship between auditors and industry 

specialties that perform company audits with transactions related to the amount of audit fees. This test is 

performed with multiple linear regressions twice. The first is multiple linear regressions by controlling the 

fixed-year effect and industry-year effect, and the second by performing multiple linear regression robustly. 

Table 6 in the first and second columns shows that LNRPT * SPECIALIST, which is an interaction 

between industry specialty auditors auditing companies with related transactions, produces a positive 

coefficient of 0.021 with a t-value of 2.01 and a significance level of 1%. This means that auditors with 

industry specializations will charge a higher audit fee on companies that carry out the related-party 

transactions. So it can be concluded that hypothesis 2 is accepted. 

 

Related-party Against Audit Fees 

Based on the results of research using Pearson correlation and multiple linear regressions, it shows 

that the related-party transactions have a positive and significant relationship to audit fees. This means that 

companies that conduct the related-party transactions tend to pay a larger audit fee to external auditors. 

This is following the hypothesis that has been proposed, so that hypothesis 1 is accepted. The related-party

transactions are an efficient contract mechanism when there is incomplete information (Ryngaert & 

Thomas, 2012). According to Gordon et al., (2007), there are several reasons why it is difficult to audit the 

related-party transactions, including the difficulty to identify the related-party transactions. Besides, the 

auditor relies heavily on information provided about related parties and the related-party transactions. The 

results of this study are in line with research conducted by Al-Dhamari et al., (2018) in Malaysia. The study 

says that sales and purchase transactions with related parties place the auditor in a situation where the audit 

risk is very significant so that the audit fee will be paid higher to the external auditor as compensation for 

the risk and effort incurred by the auditor. The increase in audit fees in this study is also in line with 

research conducted by Jiang and Son (2015) which shows the results that the auditor responds to the 

presence of control risk, the auditor will charge a fee that is higher than the cost in carrying out the audit 

itself.  

 

Industry Specialty Auditor and Audit Fees in Companies Conducting Related-party Transactions 

In addition to discussing the relationship between related-party transactions and audit fees, the 

researcher also discusses how industry specialty auditors can influence the relationship between related-

party transactions and audit fees. Previously, researchers had expected that industry specialty auditors 

would strengthen the relationship between related-party transactions and audit fees so that industry 

specialty auditors would charge a larger audit fee to companies conducting the related-party transactions. 

The results of the multiple linear regression in table 5 show that industry specialty auditors will 

charge a higher audit fee for conducting the related-party transactions so that hypothesis 2 is accepted. 

There are three reasons why the related-party transactions are difficult to disclose, namely because the 

related-party transactions are difficult to identify, all documents required to carry out the audit come from 

the company itself and finally, the internal controls that are implemented in the company do not necessarily 

identify related-party transaction (Gordon et al., 2007). Even though the auditors have performed 

appropriate audit procedures, it is possible that the auditors cannot reveal fraud from related-party 

transactions. This situation is one of the risks in the audit which is called detection risk. The  industry 

specialty auditor is one of the attributes of audit quality because it increases the likelihood of identifying 

material misstatements in financial statements (Fuentes & Sierra, 2015). Therefore, companies that carry 

out many related-party transactions are audited by industry specialty auditors, which will improve the 

quality of these financial statements because industry specialty auditors are considered capable of detecting 

errors, both errors and intentional errors. The auditor will charge a higher audit fee to the company 

following the advantages offered by the auditor. Apart from the advantages offered by the auditor, the 

imposition of a higher fee is also the auditor's response to the risks faced from the related-party transactions 

(Jiang & Son, 2015). 

 

CONCLUSION 

The results showed that related-party transactions had a positive and significant effect on the 

amount of audit fees paid to the auditors. Furthermore, the results of research that interacted with related-

party transactions with industry specialty auditors also found that industry specialty auditors strengthened 

positively and significantly the relationship between related-party transactions and audit fees. This study 

has limitations that can be considered for further research. The proxy used to measure industry specialty 

auditors was market share. However, this proxy still has disadvantages because it can generate different 

market shares. Based on the results of the previous research, the auditor should consider and assess the 

risks in carrying out the audit. This needs to be done to determine the appropriate amount of audit fee so 

that it does not harm the auditor, either at present or in the future due to audit risk. As for future research, 

it is better to use proxies to measure industry specialty auditors which do not create different results for 

market share so that it does not contain ambiguity.
