Voluntary disclosures on control system over financial reporting and corporate governance mechanisms: Evidence from Poland

The paper presents the results of research on the mechanisms of corporate governance functioning on the Polish capital market. The purpose of this article is to identify the impact of selected internal mechanisms of corporate governance on the scope of disclosures on the control system over financial reporting. Disclosures were presented by public companies operating on the capital market with an insider model of corporate governance. The research covered 301 companies listed on the Warsaw Stock Exchange and their voluntary disclosures published in 2013. The results indicate that the scope of disclosures on the control system over financial reporting is positively correlated with the presence of audit committee and the share of independent supervisory board members in their total number. The obtained research results confirm the belief presented in the literature that in an insider model of corporate governance internal mechanisms affect the scope of voluntary corporate disclosures. In addition, research results indicate that the scope of voluntary disclosures depends on the size of the company.
