The impact of corporate governance mechanisms on earnings management in Islamic banks in the Middle East region

Purpose - The purpose of this paper is to examine whether corporate governance mechanisms affect the reporting of loan loss provisions by managers in Islamic banks in the Middle East region. Design/methodology/approach -This empirical study uses balanced panel data from 20 Islamic banks, from seven Middle East countries for the period 2007 to 2011. The regression model is estimated using random effects specifications. Findings -The empirical results show that discretionary loan loss provisions (DLLP) are negatively related to board size and the existence of an audit committee. Results also report a positive relationship between sharia board size and DLLP. This indicates that small sharia supervisory boards are more effective than larger ones, which could be due to the higher costs and negative effects of large groups on decision-making. Results also highlight that the existence of scholars with accounting knowledge sitting on the sharia board reduces discretionary behavior. Additional results provide evidence that an external sharia audit committee is also found to reduce discretion in Islamic banks. The conclusions are found to be robust to endogeneity issues and potentially omitted variables. Practical implications -The findings are potentially useful for regulators and shareholders. Regulators could use the findings to focus on corporate governance mechanisms that restrain earnings management practices in Islamic banks and implement regulations to strengthen them. Additionally, this study gives shareholders further insight which enables them to better monitor the actions of managers and thus increase their control over their investments. Originality/value -This study provides two contributions to the literature on Islamic banking. First, to the authors' knowledge, this study is only the second piece of research focused on the impact of corporate governance on earnings management in Islamic banks. Second, the authors have examined the effect of some new corporate governance mechanisms that have not been studied previously in the research literature.
