This study aims to analyze the impact of corporate governance on the both voluntary risk and sustainability disclosure. I use the corporate governance attributes that are represented on board size, board independence, CEO duality, directors' ownership, blockholders' ownership, ownership concentration, and the audit committee.
Using 100 firm year observations I found a positive association between the board independence and the dependent variables risk and sustainability disclosure, and positive association between directors' ownership and the dependent variable sustainability disclosure without any effect on the risk disclosure. Moreover, I found a negative relationship between CEO duality and blockholder ownership as predictors and the dependent variables risk and sustainability disclosure. Furthermore, never have I found any relationship between the board size, ownership concentration and audit committee as predictors and the dependent variables risk and sustainability disclosure.
