Role in Listed Companies and SOX Compliance:
Internal audit plays a critical role in public and listed companies, especially under global regulatory frameworks such as the Sarbanes-Oxley Act of 2002 (SOX) in the United States.
- Section 404 of SOX mandates that management is legally responsible for establishing and maintaining an adequate internal control structure and must assess the effectiveness of these controls annually.
- SOX also requires that internal controls over financial reporting be documented, tested, and reviewed, not just internally but also as part of the external audit process.
- Internal audit ensures the presence of robust control mechanisms such as:
- Segregation of duties
- Authorization and approval protocols
- Clear documentation and audit trails
- Defined written policies and procedures
These practices safeguard the integrity of financial data, minimize fraud risk, and enhance investor confidence in corporate governance.
