Research on the Influence of the Characteristics of Independent Director to the Quality of Internal Control Self-Assessment Report ()
1. Introduction
In the process of internal control information disclosure, independent board plays a certain role. Simon and Kar [1] found that if the company sets up internal audit committee, the companies are more willing to relevant information disclosure. However, if the number of family members on the board is large, the company voluntary information disclosure level will diminish. This proves that the worse the independence of the board of directors, the less the voluntary disclosure of information.
Eng and Mak [2] studied 158 listed companies in Singapore and discussed the impact of company characteristics to internal control disclosure of information. Among them, the company features include the following aspects: size of the company, debt ratio, ownership structure, proportion of outside directors, shareholding ratio of the structure of the board of directors, government share holding ratio, and managers’ shareholding ratio. They get the following conclusions: the proportion of outside directors, board structure and ownership structure is obviously associated with internal control disclosure of information; if the shares proportion that government holds is large and the proportion of shares that company executives hold is low, the internal control information disclosure will be improved; and large companies and low debt ratio can increase the disclosure of information.
This article selects the empirical data from Shanghai A share from 2011 to 2013, using the multiple linear regression model to measure the impact to the quality of the internal control self-assessment report from four aspects of the characteristic of the independent directors.
2. The Theoretical Analysis
2.1. The Principal-Agent Theory
The principal-agent theory encourages separating ownership and management that the owners of the company give the right of management to operators, and they only keep residual claims. Therefore, operators have the important responsibilities to protect assets and complete enterprise assets value-added tasks. Although the existence of principal-agent relationship can solve the problem that owners cannot develop as a result of the limitation of professional ability, but it also brings a lot of problems behind this. If the system in the enterprise is invalid, the agent is likely to use the advantages of information they have to maximize their own interests, which will damage the interests of the principal. As a result, the principal will try every way to supervise the agent. The disclosure of the internal control self-assessment report can moderate conflict that the principal-agent relationship brought [3] - [7] .
2.2. The Theory of Internal Control
COSO [3] refers that the internal control should be implemented by the board of directors, managers and other employees, which can improve the effect and efficiency of business activities, and enhance the reliability of financial statements and assure the compliance of relevant laws and regulations. The independent director system is an important system arrangement of the internal control, and independent directors as an effective supervision mechanism, can impact on enterprise’s internal control-self assessment report. If there are independent directors in the company, it can provide reasonable assurance of the completeness of the accurate internal control self- assessment report [8] - [11] .
3. Hypothesis of This Paper
In order to make sure the company can survive in the fierce competition in the market, senior managers need to have the exquisite adept management method, accurate investment horizon, excellent communication and coordination ability and professional competence including the accounting, law and other related professional knowledge. If the independent directors is young, lacking of experience and precious practical experience, then when doing related decisions, they may make inappropriate decisions, which will affect the quality of the internal control self-assessment report [12] [13] . With the increase of age, the independent directors of rich experience, has a better understanding on the internal control, which can better improve the quality of the internal control self assessment report. As a result, the first hypothesis is proposed in this paper.
Hypothesis 1: If the independent director is older, the quality of internal control self-assessment report of the listed company is higher.
In fact, except for the independent director’s own reputation which would help them work dutifully in the listed company, the reward they receive can also make them work hard [14] [15] . Because independent directors usually have their own jobs outside company and they are not In charge of daily management, their time is valuable when providing services [16] [17] . Meanwhile, it may be risky for independent directors providing useful advices which based on their rich management experience and professional knowledge. Due to using wrong policies, independent directors must bear losses and face pressure from the company’s shareholders and other stakeholders. So it is necessary to improve the independent director’s reward to encourage them to provide higher-quality services. Above all, we put forward our fourth hypothesis.
Hypothesis 2: The higher the independent director’s reward is, the quality of the listed company’s internal control self-assessment report is higher.
In real life, due to geographical distance, time limit, the independent director cannot attend the board of directors on time or cannot attend the board of directors, this will impede independent directors to exercise their rights to the major matters and make objective and fair evaluation of enterprise, influence the “external” supervisory function of the independent director for the enterprise [18] [19] . If the negative factors decrease, the independent directors will be more willing to attend the board meeting, the number of independent directors to attend the board meeting will be increased, so the independent directors have further understanding of the situation of the company and follow up, they also can make more reasonable and objective evaluation and decision making, provide more supervision. In addition, if the independent directors and listed companies are in the same region, independent directors can more quickly and easily collect information on the enterprise, reduce the time and economic costs, in line with the economic benefit. What’s more, independent director is more likely to win first-hand information with higher credibility, which can effectively supervise on the listed companies.
Hypothesis 3: If the independent directors and listed companies are in the same place, the quality of the Internal control self assessment report of the company is higher.
4. Data and Methodology
4.1. Model
In this paper, the explained variables are the age of the independent directors, the reward of the independent directors, the location consistency of the independent directors and the company, and the dependent variable is the internal control information disclosure index (ICDI). There are control variables of eight factors in the company, including industry characteristics, the asset scale, capital structure, profitability, the joining together of two position, the nature of first big shareholders, the proportion the first big shareholders holding and the time variable. As a result, the multiple linear regression model is established in this paper [20] .
ICDI = α + β1AGE + β2PAY + β3PLACE + β4IND2 + β5IND3 + β6IND4 + β7IND5 + β8SIZE + β9LEV + β10ROA + β11CEO + β12 SHAREC + β13SHARE1 + β14YEAR2012 + β15YEAR2013 + ε
4.2. Instructions of Variables
ICDI is a percentage value, it gets scores from four aspects of the internal control self-assessment report, and the sum scores finally is divided by total score of 80 points. The internal control self-assessment is scored according Table 1.
Age is the average age of the independent directors in the listed company.
PAY is the logarithmic average total reward of independent directors.
PLACE is a dummy. Only if the location of the independent directors is consisted with the location of the company, its value is 1, other with 0.
IND2 is a dummy. Only if the industry is real estate industry, its value is 1, other with 0.
IND3 is a dummy. Only if the industry is comprehensive industry, its value is 1, other with 0.
IND4 is a dummy. Only if the industry is industrial, its value is 1, other with 0.
IND5 is a dummy. Only if the industry is commerce industry, its value is 1, other with 0.
SIZE is the exponential value of the enterprise total assets at the end of last year.
LEV is asset-liability ratio, that is the value of total liabilities divided by total assets.
CEO is a dummy. Only if the chairman is also a general manager, its value is 1, other with 0.
SHAREC is a dummy. Only if the nature of the largest shareholder is state-owned shares, its value is 1, other with 0.
SHARE1 is the stake of the largest shareholder.
YEAR2012 is a dummy. Only if the year is 2012, its value is 1, other with 0.
YEAR2013 is a dummy. Only if the year is 2013, its value is 1, other with 0.
4.3. Data Source
The article selects Shanghai A-share companies in 2011 to 2013 as the research sample, choose the annual internal
control self-assessment report one year as the research object, eliminating missing data, in total there are 1647 observations. All the data is from CSMAR database and the prospectus of the company, processed through Microsoft Excel 2007 and STATA statistical software.
5. Empirical Results
5.1. Descriptive Statistics
According to Table 2, the average age of independent directors is 55, and the youngest independent director is 38 years old, and the oldest independent director is 74 years old. It shows that in most companies, there are many middle-aged independent directors who are full of experience. The average value of the pay of the independent directors is 4.761, it shows that the average reward of the independent directors is 57676 Yuan. The minimum value of the consistence of the location of the independent directors and the companies is 0, and the maximum value is 1, it shows that some independent directors’ location is consistent with the company’s location. The mean value of this index is 0.546, it shows that more than half of the independent directors are in the same place with the company.
5.2. Multiple Regression Results
According to Table 3, we can know that the value of R2 is 0.23, and the adjusted value of R2 is 0.21, it shows that the model fits better. And the variables can explain 23% of the dependent variable quality of the internal control self-assessment report. Even though change the number of R2, the model can still explain 21% of the information. And the mean of the VIF is 1.24, lower than 10, it shows that there is no multicollinearity problem in this model.
6. Conclusions
In conclusion, if the independent director is older, the quality of internal control self-assessment report of the listed company is higher.
Table 3. The result of multiple regression.
However, if the pay of independent directors is high, it doesn’t mean that the quality of internal control self-assessment report of the listed company will be high. Because if the pay is very high, it will damage the independence of the independent director, which will affect the quality of the internal control self-assessment report. Besides, if the independent directors and listed companies are in the same place, it doesn’t mean that the quality of internal control self-assessment report of the listed company will be high. As independent directors can get much information from all the aspects including the meeting, it won’t take any effects even though the independent board can’t attend the meeting because of the long distance.
