It when companies report large profits, people become asked whether this is really real profit or profit that is intentionally made for a particular purpose. Departing from this, we made a study of income smoothing in the mining sector. Mining sector is one sector that is classified as profitable for people; this sector can be called an opportunist and opportunist sector often associated with earnings management and income smoothing. Our research is quantitative research. We use secondary data, financial statements of mining companies for the past five years. We use path analysis for the analysis tools in this study. We use three moderator variables, namely: institutional ownership, managerial ownership and audit committee. We examine the three moderator variables whether they can moderate profitability and leverage on income smoothing. The results of our study state that profitability influences income smoothing. In addition managerial ownership is able to moderate profitability and leverage, while the audit committee is only able to moderate profitability on income smoothing. Key words: corporate, governance, income, smoothing, mining, company Cite this Article: Bambang Leo Handoko and Daniel Yosia Arbi, How Corporate Governance Able to Moderate Income Smoothing in Mining Sector.

INTRODUCTION Financial report is the source of company financial information. The financial report can show the readers about the company's performance which is expected to help the company's stakeholders on making economic, political and financial decisions. Financial reports consist of statements of financial position or sometimes called as balance sheets, profit & loss reports or sometimes called as income statements, statements of equity changes, cash flow statements, and notes to financial statements. From all the sections in the financial report, the part that most investors or external parties such as creditors, government, and other external http://www.iaeme.com/IJM/index.asp 486 editor@iaeme.com
  2. Bambang Leo Handoko and Daniel Yosia Arbi parties see is the profit generated by the company in the profit and lost report. The profit and loss statement can show the company performance by looking at their ability to generate profits. The more profit company generates means that the company's performance is good and has a long-term survivability promising. Company management often sees this as the opportunity to gain more investors for the company which leads to dysfunctional behavior. The huge attention given to the profit and loss section has been one of the management's motivations for doing dysfunctional behavior [1]. One of the manager's dysfunctional behaviors is income manipulation or sometimes called as earnings management. Earning management itself is well-known in Indonesia. There are several cases which are related to earnings management. One of the cases is the case of Kimia Farma. The fact that happened in 2001, Kimia Farma marked up their income around IDR 32.3 billion which is caused by the management making 2 different master prices [2] and [3]. According to [4], one of earnings management behavior is income smoothing and the way to make is by making the income more stable by minimizing the volatile income. One of the ways to minimize the fluctuating income is by moving the income from the year that has a high income to the year that has a low income. With this method, the company’s income will become stable with expectations that they will gain more investors. Income smoothing is one of earnings management done by managers to fulfill their interests. This is related to agency theory that explains about agents and principles' different interests which will affect the company's performance towards their goals. Based on this theory, earnings management can be reduced by the company's good corporate governance. This statement is also in line with [5] who said that agency theory can be reduced by corporate governance mechanisms. 2. LITERATURE REVIEW AND HYPOTHESIS 2.1. Financial Leverage Financial Leverage is the use of debt as the source of money to finance the company's operations and generates profits for the company. One of the ratios to calculate financial leverage is debt to equity ratio (DER). In the debt covenant hypothesis, companies with a high debt to equity ratio will have a high possibility on doing the practice of earnings management by selecting accounting procedures that can transfer future income towards current income [6]. The research of [7] uses the banking sector company only shows that financial leverage with DER as the proxy influences income smoothing practice. While, [8] and also [9] which uses mining company sector can show that financial leverage with DAR as the proxy can positively influence income smoothing practice. There is also research from [10] that shows financial leverage using ROA as the proxy doesn't influence the practice of income smoothing company in IDX. Based on the above analysis, the hypothesis will be: H1: financial leverage proxies as DER affect the practice of income smoothing. 2.2. Profitability Profitability is the company's ability to generate income in a certain period of time. According to the bonus plan hypothesis in the positive accounting theory, company profitability can also be one of the factors that can affect the practice of income smoothing in the company. [11] said that management companies prefer accounting methods that help the company increase their current profit period with their expectation bonuses can increase too. There are many ratios to calculate company’s profitability. However based on [12], ROA also may not be the perfect measure, but it is the most effective tool to measure company performance. Therefore, this research will use ROA as the proxy for profitability ratio. http://www.iaeme.com/IJM/index.asp 487 editor@iaeme.com
  3. How Corporate Governance Able to Moderate Income Smoothing in Mining Sector The research of [13] shows that profitability using ROA as the proxy does affect the probability of income smoothing. This is also supported by the research of [11] that give more detailed results by saying that profitability has a negative effect towards income smoothing. This means that the lower the profitability ratio the company has, the more likely they will do smoothing income to make their profit look good. Based on the above analysis, the hypothesis will be: H2: profitability proxies as ROA affect the practice of income smoothing. 2.3. Institutional Ownership Institutional ownership is a corporate governance mechanism that can help weaken the probability of income smoothing occurrence because institutional ownership means that the company has an outside party that acts as their shareholders and monitors. This outside party sometimes we are called as institutional owner. [14] said that institutional investors can increase the efficiency of monitoring management activities because they can provide active monitoring systems and have more capabilities than smaller investors by having better resources and opportunities to do the monitoring. This statement is supported by the research of [15] and [16] that said institutional can weaken the influence of financial leverage towards income smoothing. Therefore, based on the analysis above the hypothesis will be: H3a: Institutional ownership moderates the influence of financial leverage towards income smoothing. Based on the bonus plan hypothesis in the positive accounting theory, profitability is one of the factors that affect the practice of income smoothing. It is because one of the reasons for management to do income smoothing is to make their profitability stable. Institutional ownership as one of the corporate governance mechanisms can help weaken this effect with the presence of the institutional owners such as banks and financial institutions as their monitors. The research done by [15] shows that there is no relationship between institutional ownership and income smoothing which means that institutional ownership cannot affect earnings management even if it is put as a moderating variable. However, based on previous study by [17], it shows that ownership structure and concentration can affect the income smoothing by reducing it. The research also uses institutional ownership as the moderating variable. This different opinion is backward one to another. That's why the hypothesis will be: H3b: Institutional ownership moderates the influence of profitability towards income smoothing. 2.4. Managerial Ownership One of the factors that affect practice of income smoothing is the agency problem where the management of the company only thinks about themselves. In order to minimize the agency problem, the company must increase the managerial ownership [18]. With the existence of managerial ownership in a company, it can align the potential differences in interests between shareholders and the management. This is supported by the research of [19] which also said that managerial ownership can weaken the influence of financial leverage towards income smoothing. However, based on [6] financial leverage does not influence the probability of income smoothing and managerial ownership cannot be the moderation. Therefore, with these different sayings about managerial ownership which affects the relationship between financial leverage and income smoothing, the hypothesis will be: H4a: managerial ownership moderates the influence of financial leverage towards income smoothing. http://www.iaeme.com/IJM/index.asp 488 editor@iaeme.com
  4. Bambang Leo Handoko and Daniel Yosia Arbi Profitability shows the company's ability to generate income in a period of time. The higher the profitability ratio will indicate the better company's performance. This is supported by the research of [20] that shows managerial ownership can weaken the influence of profitability towards the probability of income smoothing. With the existence of profitability as the factor that affects the income smoothing practices; this research aims to see whether the existence of managerial ownership can reduce the practice of income smoothing. H4b: managerial ownership moderates the influence of profitability towards income smoothing. 2.4. Audit Committee Based on the debt covenant hypothesis in positive accounting theory, one of the factors that affect the practice of income smoothing is the company's high debt and the probability of the company's bankruptcy. This factor is related to the financial leverage factor. One of the ways to decrease / weaken the influence of financial leverage factors towards income smoothing is the audit committee size inside the company. Audit committees are made of to be in charge of monitoring the company and controlling the information provided by the company. The bigger the size of the audit committee, the more scope of the audit committee can monitor. This is supported by the research of [9] which also said that the audit committee can weaken the influence of financial leverage towards income smoothing. However, based on [21] and [22] the audit committee did not have an effect on the influence of financial leverage towards the probability of income smoothing, the hypothesis will be: H5a: audit committee size as moderates the influence of financial leverage towards income smoothing. As stated on the bonus plan hypothesis, managers tend to use accounting methods that can benefit them to get their bonuses. One of the ways is to increase the company's profitability by doing income smoothing. Corporate governance is one of the internal controls that can help companies prevent the practice of income smoothing. The audit committee which is part of the company's corporate governance can be the key decrease / weaken the influence of profitability factors towards income smoothing. This is supported by the research of [22] that earnings management is less likely to occur when the composition of the audit committee is good. Therefore, with this opinion, the hypothesis will be: H5b: audit committee size moderates the influence of profitability towards income smoothing. 3. RESEARCH METHODOLOGY 3.1. Research Object The research object that is used to see whether good corporate governance and financial leverage influence the practice of income smoothing is the mining company sector that is listed in IDX and the year taken is from 2014-2018. This research is quantitative research. For the data itself, this research will be using secondary data which means the data will be taken from outside sources such as previous research, official websites, etc. For this research the data will be taken from the Indonesia stock exchange www.idx.co.id. 3.2. Sample Determination This research is a quantitative research method with case study research. Data sources are primary and secondary data, primary data is entirely obtained from the research object and secondary data is obtained from the company database. Data collection is done by observing (observation), questionnaire and documentation. Determination of the sample is done by the Purposive Sampling method. Purposive Sampling is a sampling technique that uses criteria http://www.iaeme.com/IJM/index.asp 489 editor@iaeme.com
  5. How Corporate Governance Able to Moderate Income Smoothing in Mining Sector that have been selected by researchers in selecting sampling. Sample selection criteria are divided into inclusion and exclusion criteria. The population in this research will be companies in mining sector that is listed in Indonesia stock exchange with a range year of 2014-2018. To determine the sample, this research will be using purposive sampling as the sampling method. 3.3. Data Analysis Method The data analysis method used in this research will be using path analysis. In this research, we will be using ratio to calculate our income smoothing as our dependent variable. Therefore, in this research the method used is multiple regression analysis technique. Data that is collected will be presented in a form that is easily understood by the reader. All the results of the research will be presented in the form of tables and pictures. Each table and picture will have an explanation to describe the table or pictures 3.4. Operation of Variables These are the operation of variables based on and other previous research to measure the variables, presented in Table 1 Table 1 Operation of Variables No Variable Indicator Scale Dependent Variable 1 Income Smoothing (Y) DAit = (TAit/Ait-1) - NDAit Ratio Independent Variable 1 Financial Leverage (X1) Total Liabilities/Total Equity Ratio 2 Profitability (X2) Net Income/Total Asset Ratio Moderating Variable 1 Institutional Ownership (Z1) Institutional Shares/Total Company Share Ratio 2 Managerial Ownership (Z2) Manager Share/Total Company Share Ratio 3 Audit Committee Size (Z3) Audit Committee Size Ratio 4. RESULT AND DISCUSSION 4.1. Normality Test Normality test is a test that helps determine whether our research data have distributed normally or not. By having a normally distributes research data sample, the data sample can be considered represent the population. Normality test can use One Sample Kolmogorov- Smirnov method. In Kolmogorov-Smirnov method, the distribution of data is determined by looking at the significance value. If the significance value is above 0.05, means that the data is distributed normally. However, if the significance value is below 0.05, means that the data is not normally distributed. Based on the One Sample Kolmogorov-Smirnov test result, the significance value of 2 tailed is 0,200. This result shows that the data sample in this research is distributed normally because 0,200 which is more than 0.05. http://www.iaeme.com/IJM/index.asp 490 editor@iaeme.com
  6. Bambang Leo Handoko and Daniel Yosia Arbi Table 2 Normality Test 4.2. Multicollienarity Test Multicollinearity test is used to see whether there are interactions or correlation between the independent variable. Multicollinearity test is used to analyze independent variable that is more than 1. A good regression model must free from multicollinearity. Regression model that are free from multicollinearity is a regression model that have VIF (Variance Inflation Factor) smaller than 10 and tolerance value more than 0.1. Table 3 Multicollinearity Test Collinearity Independent Variables VIF Tolerance ROA 0,726 1,378 DER 0,808 1,237 Institutional Ownership 0,762 1,313 Managerial Ownership 0,726 1,377 Audit Committee Size 0,838 1,193 Based on the multi-collinearity test result above, there is no correlation between all the independent variables in this research. The VIF from ROA, DER, Institutional ownership, Managerial ownership, and Audit committee size are 1,378; 1,237; 1,313; 1,377; 1,193. The VIF value above shows all are smaller than 10. The collinearity tolerance also indicates the same thing. The tolerance from ROA, DER, Institutional ownership, Managerial ownership, and Audit committee size are 0,726; 0,808; 0,762; 0,726; 0,838. The tolerance from all the variables is above 0.1. Therefore, there are no multi-collinearity between all the variables in this research. 4.3. Heteroscedasticity Test Heteroscedasticity test is used to see whether there is variance dissimilarity from the residual on one observation to the others (data cross-sectional). In this research, the heteroscedasticity test will be using Spearman Correlation test. http://www.iaeme.com/IJM/index.asp 491 editor@iaeme.com
  7. How Corporate Governance Able to Moderate Income Smoothing in Mining Sector Table 4 Spearman Correlation Test Independent Variables Significance ROA 0,948 DER 0,914 Institutional Ownership 0,952 Managerial Ownership 0,698 Audit Committee Size 0,757 In Spearman Correlation test, if the significant value of independent variable’s residual more than 0.05 means that the regression model doesn’t have heteroscedasticity problem. Based on the result of Spearman Collinearity test, the entire variable’s significance is above 0.05, which means there are no heteroskedasticity problems. 4.4. Autocorrelation Test Autocorrelation test is used to see whether the regression model have correlation between residual in t period with residual in t-1 period. If there is correlation, means the regression model have autocorrelation problem. In this research the autocorrelation test will be using Run Test. In run test, if the asymp. Sig (2-tailed) value is above 0.05, means that the regression model doesn’t have autocorrelation problem. However, if the value is below 0.05, means that the regression model have autocorrelation problem. Based on the result, the asymp sig (2-tailed) is 0,438 which is above 0,05. With this result, we can conclude that the regression model in this research doesn’t have autocorrelation problem. Table 5 Autocorrelation Test 4.4. Hypothesis Test The hypothesis testing in this research uses t-test and path coefficient. The hypothesis testing is used to determine the influence of profitability proxies by ROA (Return-on-Asset) and financial leverage proxies by DER (Debt-to-Equity Ratio) towards income smoothing with institutional ownership, managerial ownership, and audit committee size as the moderating variables. The t test result is presented on table 6. Profitability variable proxies by ROA (Return-on-Asset) have a significance value of 0,000 which is smaller than 0.05. Therefore, indicate that profitability variable proxies by ROA can affect the practice of income smoothing significantly; hypothesis 2 accepted, our result in line with [8]. http://www.iaeme.com/IJM/index.asp 492 editor@iaeme.com

Therefore, indicate that financial leverage variable proxies by DER cannot affect the practice of income smoothing significantly. Hypothesis 1 rejected. This is support previous study by [23]. Institutional ownership did not moderate the influence of both profitability and financial leverage. It can be seen on the result that p-value of Z1.X1 is 0.485 and Z1.X2 is 0.406 which is higher than 0.05. It means that both hypothesis 3a and 3b are rejected. This result similar with the result on [16] and [14]. Managerial ownership moderates the influence of both profitability and financial leverage. It can be seen on the result that p value of Z2.X1 is 0.032 and Z2.X2 is 0.009 which is lower than 0.05. It means that both hypothesis 4a and 4b are accepted. Our result in line with [15] and [19]. Audit committee size moderates profitability, it can be seen based on p-value of 0.039 which is below 0.05, but audit committee do not moderates financial leverage, as it show p- value of 0.095 which is higher than 0.05. Hypothesis 5a is accepted, but hypothesis 5b is rejected. Our result support previous study by [22]. The path coefficient was stated on figure 1. Figure 1 Path Coefficient 5. CONCLUSION 5.1. Conclusion Profitability affects earnings management because the main purpose of income smoothing is to increase or reduce profits, depending on the goals to be achieved by business entities. Leverage usually in a lot of previous research has significant effect on income smoothing, but in our study it didn’t. Our sample, mining companies were typically matured company, rarely new comers business, since the barrier to entry was high. In order to a mining company can be http://www.iaeme.com/IJM/index.asp 493 editor@iaeme.com
  9. How Corporate Governance Able to Moderate Income Smoothing in Mining Sector listed in stock market, it means that they must be a matured company with large portion of asset. Competition in this sector not as tight as other sector like retail or manufacture, even large debt didn’t indicates probability of bankruptcy but in opposite trust from creditor, acknowledgement of matured company. Institutional ownership didn’t moderates both profitability and leverage. Institution investors in mining company sector didn’t have the chance to limit management behaviors and only focuses on current earnings. Therefore, institutional owners cannot be ascertained to help minimize earning management. Differ from institutional ownership, managerial ownership play important role in earnings management. It can moderate both profitability and leverage. It is because most board of director or related family also own significant portion of share ownership. The result of profit and level of leverage will determine their achievement as top management. Audit committee plays important role in income smoothing. Profit raise became main concern of committee, since a lot of case derived from overstatement of profit, but leverage didn’t become main concern of committee. Since large amount of leverage didn’t has direct related with company poor performance. In opposite, large amount of approved debt shows lender trust to the company. Large amount of debt will be fine, if the company know how to spend it on the right place and also has financial planning to pay the debt. 5.2. Suggestion Based on the results obtained, the following are suggestions Shareholders should pay attention to profitability, it will be better to set target profits at reasonable manner, so it will not trigger pressure to do income smoothing. Managerial ownership able to moderate income smoothing, since share holder which also work as management understand well the working condition of company, so they rarely provide too high target, since themselves will carry on the target. The present of audit committee is important, so the company should consider to increases numbers of committee, especially independence committee, so it can work more effective Another researcher in the future can use our study as reference. They can study about mining sector in various countries, either developed or new emerging countries. It will be better in country which mining becomes main driver of gross domestic product, so it will play important role for macro-economic of that country REFERENCES [1] D. N. Herda and K. A.
