Model Audit Rule (MAR)

The Model Audit Rule (MAR) is a regulatory framework developed by the National Association of Insurance Commissioners (NAIC) that establishes financial reporting, internal control, and audit requirements for insurance companies.

Often compared to the Sarbanes-Oxley Act (SOX) for publicly traded companies, MAR is specifically designed for the insurance industry. It helps promote accurate and reliable financial reporting by requiring organizations to maintain effective internal controls, undergo independent audits, and demonstrate the integrity of their financial reporting processes. 

Model Audit Rule Requirements

The Model Audit Rule (MAR) establishes requirements that help insurance companies strengthen internal controls, improve financial reporting, and enhance corporate governance. To comply with MAR, organizations must maintain an effective compliance program, support management certifications, and demonstrate that these controls are operating effectively on an ongoing basis.

Key MAR requirements include:

  • Implementing an effective internal control framework over financial reporting
  • Providing annual financial reports certified by management
  • Undergoing independent external financial audits
  • Reporting material weaknesses in internal controls to the board of directors or audit committee
  • Maintaining documentation and evidence to support continuous compliance 

Because MAR compliance is continuous rather than a one-time exercise, organizations should regularly review their controls, address identified deficiencies, and remain prepared for audits and annual reporting requirements. Together, these practices promote transparency, reduce the risk of fraud, and improve the integrity of financial reporting.

Model Audit Rule Controls

Effective internal controls are the foundation of Model Audit Rule (MAR) compliance. The following control areas help organizations strengthen financial reporting, manage risk, and meet MAR requirements: 

Risk Assessment

Organizations should identify and evaluate risks that could affect the accuracy of financial reporting. Regular risk assessments help prioritize controls and address emerging threats.

Control Activities

Control activities are the policies and procedures used to mitigate identified risks. Examples include approvals, reconciliations, segregation of duties, and access controls.

Information and Communication

Reliable systems should support the collection, sharing, and reporting of financial information. Timely communication helps employees carry out their responsibilities and supports informed decision-making.

Monitoring

Internal controls should be continuously monitored and periodically tested to confirm they remain effective. Organizations should also update controls as regulatory requirements and business operations evolve.

Model Audit Rule vs. SOX

The Model Audit Rule (MAR) and the Sarbanes-Oxley Act (SOX) both strengthen financial reporting and internal controls, but they apply to different types of organizations.

Model Audit Rule (MAR)

  • Applies primarily to insurance companies
  • Issued by the National Association of Insurance Commissioners (NAIC)
  • Focuses on financial reporting, internal controls, and corporate governance within the insurance industry

Sarbanes-Oxley Act (SOX)

  • Applies to publicly traded companies in the United States
  • Regulated by the U.S. Securities and Exchange Commission (SEC)
  • Establishes broad financial reporting, internal control, and audit requirements across all public industries

Although MAR incorporates many of the same principles as SOX compliance, it is tailored specifically to the operational and regulatory needs of insurance organizations. Like SOX, MAR requires management certifications, independent audits, and effective internal controls to improve the accuracy and integrity of financial reporting. 

Model Audit Rule History and Key Amendments

The Model Audit Rule (MAR) has evolved over time to strengthen financial reporting, corporate governance, and internal controls within the insurance industry. These updates have improved the reliability of financial reporting and corporate governance across the insurance industry while adapting MAR to evolving regulatory expectations. The table below highlights key milestones in the rule’s development.

Model Audit Rule Implementation Guide

Implementing the Model Audit Rule (MAR) requires insurance companies to establish effective internal controls, prepare for audits, and maintain continuous compliance with NAIC requirements. The following steps provide a practical roadmap for implementing MAR:

1. Assess Current Processes

Begin by evaluating your existing financial reporting processes and internal controls to identify compliance gaps. This assessment provides a baseline for determining what improvements are needed to meet MAR requirements.

2. Build an Internal Control Framework

Develop and document internal controls over financial reporting that align with MAR requirements. Clearly assigning control owners, documenting procedures, and defining responsibilities helps strengthen governance and accountability.

3. Prepare for Audits

Organize documentation and collect evidence demonstrating that internal controls are operating effectively. Conducting readiness assessments before an external audit can help identify and remediate issues early.

4. Complete Annual Reporting

Prepare annual financial reports that include management’s certification of the effectiveness of internal controls over financial reporting. Accurate reporting helps demonstrate continuous compliance with MAR requirements.

5. Monitor and Improve

MAR compliance is an ongoing process that requires continuous monitoring of internal controls and regular reviews of financial reporting processes. Addressing control deficiencies promptly helps organizations remain compliant and audit-ready year after year.
