Denetim komitelerinin firma performansı üzerine etkisi: BİST şirketleri üzerine bir uygulama

Recently, corporate governance mechanisms, such as the audit committee, have gained importance in order to protect the interests of shareholders and stakeholders following the occurrence of several accounting and audit scandals. Therefore, Turkey, as well as a number of countries, are required to establish audit committees in public companies. The purpose of this study is to investigate the impact of audit committee characteristics (audit committee independence, financial expertise, gender, meeting frequency, and age average) on the firm performance of listed companies in Borsa Istanbul (BIST). Return on Assets (ROA), Return on Equity (ROE), and Tobin's Q were used as proxies for firm performance based on former academic research in this related area of study. Data was obtained from a sample of 102 non-financial companies listed on BIST for the period 2006-2016 which was analyzed using multiple linear regression analysis. Findings show that there is a positive significant relationship between independence and gender of audit committee members and ROA, ROE, and Tobin's Q. However, age average has a negative significant relationship with ROA and ROE. Financial expertise and meeting frequency revealed no significant relationship between all the dependent variables.
