Corporate governance is the system by which companies are directed and controlled. It establishes the framework for accountability, transparency, and fairness through policies, processes, laws and institutions. The key principles of corporate governance according to OECD are the rights of shareholders, equitable treatment of shareholders, role of stakeholders, disclosure and transparency, and board responsibility. Stakeholders in corporate governance include employees, suppliers, government, customers, shareholders and investors. Factors for evaluating corporate governance are regulations on non-executive directors, constraints on management power, disclosure requirements, and board accountability.
