Abstract
This report assesses the corporate governance performance of 582 top publicly listed companies in Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Viet Nam using the revised ASEAN Corporate Governance Scorecard (ACGS). The mean total score of top publicly listed companies rated increased by 12% in 2019 compared to 2017, showing improvement in corporate governance practices. The revised ACGS comprises five parts based on the Organisation of Economic Co-operation and Development's principles: shareholders' rights, equitable treatment of shareholders, stakeholders' role, disclosure and transparency, and board responsibilities.
