Audit Committee Roles.
1. Overview of the Audit Committee in Banks
An Audit Committee (AC) is a specialized subcommittee of a bank’s board of directors, primarily responsible for financial reporting, internal controls, compliance, and risk oversight. Banks have complex operations and high systemic importance, so the audit committee ensures transparency, accountability, and governance integrity.
Key Purpose:
Safeguard stakeholders’ interests.
Ensure accurate financial reporting.
Monitor internal controls and risk management.
Strengthen the bank’s governance framework.
2. Key Roles and Responsibilities
A. Financial Reporting Oversight
Review quarterly and annual financial statements.
Ensure compliance with accounting standards (IFRS, GAAP).
Discuss significant accounting policies and judgments with management and auditors.
B. Internal Control Oversight
Assess effectiveness of internal controls for operations, IT systems, and financial reporting.
Review reports from internal audit teams and ensure timely remediation of deficiencies.
C. Audit Oversight
Appoint, monitor, and liaise with external auditors.
Review audit plans, audit findings, and management responses.
Ensure independence and objectivity of auditors.
D. Regulatory Compliance Oversight
Monitor adherence to laws, banking regulations, AML/KYC standards, and corporate governance requirements.
Oversee compliance reporting to regulators.
E. Risk Governance Support
Support the board in overseeing credit, market, operational, and liquidity risks.
Review risk reporting frameworks and internal risk assessment procedures.
F. Fraud and Ethical Oversight
Evaluate whistleblower complaints and allegations of fraud or misconduct.
Promote ethical behavior and corporate integrity.
