Introduction: Audit committees are fundamental components of corporate governance frameworks, tasked with overseeing financial reporting, risk management, and internal controls. Whether under the US corporate governance system, shaped by the Sarbanes-Oxley Act (SOX) of 2002, or the UK Corporate Governance Code, audit committees play a pivotal role in ensuring the integrity, transparency, and accountability of a company’s financial practices. Composed primarily of independent non-executive directors, these committees serve as an essential link between the board of directors, external auditors, and shareholders. By safeguarding the accuracy of financial statements and monitoring compliance with legal and regulatory standards, audit committees contribute to investor confidence and the overall health of capital markets.
