Corporate governance is important for companies to protect shareholder interests and manage risks. It involves transparency, accountability, and oversight between key stakeholders like shareholders, management, and boards of directors. Not applying effective governance can lead to financial failures, loss of shareholder rights, and lack of transparency deterring investment. Risks include mismanagement, abuse of power, loss of foreign investment, and withdrawal of capital. Governance aims to standardize responsibilities and achieve fairness, efficiency, and optimal resource use through transparency and accountability.
