The role of audit committee quality on the financial performance of public and private banks admitted to the stock exchange

With technological change and globalization, financial markets faced competitive pressure to improve performance. One of the ways to deal with these pressures is the establishment of private banks. The audit committee, as an important part of the corporate governance system, can lead to the improvement of the company's performance and financial reporting process. The purpose of this research is to investigate the role of audit committee quality on the financial performance of public and private banks admitted to the stock exchange. This research is applied in terms of purpose and correlational in terms of nature and causal method. The statistical population of the research was all the banks admitted to the stock exchange in the period of 5 years from 1395 to 1399. The dependent variable of financial performance research includes bank profit and liquidity. The independent variable of audit quality research includes size, independence, expertise and the number of audit committee meetings. A generalized regression model has been used to test the research hypotheses. The findings of the research showed that in private banks, the size of the audit committee has a positive and significant effect on bank profit, and other characteristics of the audit committee do not have a significant effect on bank profit. Also, the size, independence and expertise of the audit committee has a positive and significant effect on the performance of state banks (profit and bank liquidity). Also, this effect is greater in public banks than in private banks. These findings show that the financial performance of the bank will also increase with the increase in the quality of the audit committee.
