摘要：This study aims to examine the impact of ownership structure and board composition on the level of voluntary disclosure by non-financial firms listed in the Amman Stock Exchange (ASE). The study uses panel hand-collected data from 443 annual reports for a 5-year period (2012 2016) and employs an OLS-regression to test the study predictions. Compatible with the study predictions and most prior related studies' findings, both higher managerial ownership and the CEO-duality produce low levels of voluntary disclosure, while foreign ownership is positively associated with the level of voluntary disclosure. Findings also indicate that larger firms deemed to provide higher levels of voluntary disclosures than smaller firms. Besides, companies audited by big4 firms disclose more voluntary information than those audited by others. The study findings have implications for policymakers and regulators. Policymakers and regulators may encourage, emphasize and enforce, if necessary, the regulation that enhances the quality of financial disclosures including the separation between the Chairman of the board of directors and CEO roles to improve the level of control and supervision and enhance the transparency of financial reporting by Jordanian firms.
