What Is Model Audit Rule?

The Model Audit Rule (MAR) is a regulation introduced by the United States National Association of Insurance Commissioners (NAIC) to ensure the accuracy and reliability of financial reporting by insurance companies. Furthermore, it aims to address potential risks associated with inaccurate or unreliable financial reporting.

Model Audit Rule - Definition

The rule requires insurance companies to establish and maintain adequate internal controls over their financial reporting processes, including using models for risk assessment, pricing, reserving, and other financial calculations. Moreover, it helps to enhance transparency, accountability, and confidence in the financial reporting of insurance companies.

  • Model Audit Rule (MAR) is a set of rules created for insurance companies to ensure their financial reporting is accurate and reliable.
  • Hence, it ensures insurance companies have proper internal controls and risk management systems.
  • Moreover, this rule is specific to the insurance industry and addresses the unique risks and challenges that insurance companies face. Conversely, SOX applies to publicly traded companies across sectors and encompasses broader requirements to enhance corporate governance, financial reporting, and investor protection.

Model Audit Rule Explained

The model Audit Rule (MAR) refers to a set of regulations established by the National Association of Insurance Commissioners (NAIC) in the United States. Additionally, this rule was created to provide a framework for insurance companies to evaluate and manage their financial and operational risks effectively.

Therefore, the rule aims to enhance insurers' financial reporting's transparency, accuracy, and reliability, particularly concerning their models used for financial projections and risk assessments. The three primary purposes of this rule are explained in detail.

#1 - Strengthening Internal Controls

Model audit rule requires insurance companies to establish robust internal controls and governance procedures for their models. Thus, this includes implementing a comprehensive system of checks and balances to ensure the accuracy and integrity of the models used for financial reporting.

#2 - Independent Model Audits

These rules mandate that insurance companies subject their models to independent audits by qualified external auditors. Thus, the auditors should possess the necessary expertise and independence to assess the models thoroughly.

#3 - Reporting And Compliance

They require insurance companies to disclose information regarding their models and the associated risks in their annual financial statements. Moreover, the companies must provide detailed documentation on their models' design, methodologies, key assumptions, and limitations.

Moreover, the model audit rule testing process involves evaluating various aspects of the model to ensure they meet regulatory requirements. Hence, compliance with the model audit rule in the insurance industry aims to:

  • Enhance risk management practices
  • Protect policy holder's interest
  • Maintain the stability of the insurance market

Furthermore, the model audit rule encourages insurance companies to comply with applicable regulatory requirements and industry best practices in modeling and risk management.

Requirements

Insurance companies must comply with the requirements set forth by the Model Audit Rule (MAR).

Here are some critical requirements of this rule:

  1. Internal Controls and Governance: Insurance companies must establish and maintain a robust system of internal controls and governance procedures for their models. It includes:
    • Designating personnel responsible for model development, implementation, and maintenance.
    • Implementing clear policies and procedures for model development and usage.
    • Establishing documentation standards to record the design, assumptions, methodologies, and limitations.
  2. Independent Model Audits: This rule mandates that insurance companies subject their models to independent audits by qualified external auditors. Thus, the critical aspects of independent model audits include the following:
    • Engaging independent auditors with the expertise and independence to objectively evaluate the models.
    • Auditing the design, assumptions, methodologies, calculations, and overall effectiveness of the models.
    • Reviewing the documentation and validation processes associated with the models.
  3. Reporting and Disclosure-Insurance companies must provide comprehensive reporting and disclosure regarding their models and associated risks. Therefore, this includes:
    • Including detailed information on the models used, their purpose, and the risks they address in the company's annual financial statements.
    • Disclosing the key assumptions, methodologies, and limitations of the models.
    • Ensuring compliance with regulatory reporting requirements and guidelines.
  4. Compliance with Regulatory Requirements:  They emphasize the importance of compliance with applicable regulatory requirements and industry best practices in modeling and risk management. Insurance companies are expected to:
    • Understand and adhere to the relevant laws, regulations, and modeling and risk assessment guidelines.
    • Keep abreast of updates and changes to regulatory requirements and adjust their models and practices accordingly.
    • Implement industry-recognized best practices for model development, validation, and usage.

Example

Let's assume that Aflac Insurance Co. develops a financial model to estimate claim reserves for their auto insurance policies. Therefore, this model requires them to comply with specific guidelines and undergo independent audits to ensure the accuracy and reliability of the model.

Hence, the insurance company documents the model's methodologies, assumptions, and data sources by including information on historical claims data, market trends, and actuarial principles.

Therefore, they engage an independent auditing firm to audit the model. Hence, the auditors review the model's design, assumptions, and calculations to ensure compliance with the model audit rule. Overall, they validate the accuracy of input data, assess the reasonableness of beliefs, and compare the model's outputs to actual claim experience.

During the audit, the auditors identified a discrepancy in one of the assumptions used in the model. Thus, the insurance company promptly investigates the issue, corrects the assumption, and updates the model accordingly.

Moreover, by complying with the rule and conducting independent audits, the insurance company ensures that its financial model accurately estimates claim reserves, promotes transparency, and enhances risk management practices.
