Which of the following is NOT a type of audit in insurance?

The correct choice identifies a type of audit that does not typically fall under the recognized categories of audits used in the insurance industry. An audit in insurance is usually classified into different types based on how it is conducted and the parties involved.

Onsite audits conducted by internal staff allow companies to assess their own practices, ensuring compliance and identifying potential improvements from within. Outsourced audits to an external audit firm leverage specialized knowledge and objectivity, helping insurance companies achieve a level of impartiality and expertise. Voluntary audits, while not mandated by regulatory bodies, are often undertaken by insurance companies to verify their practices and compliance voluntarily.

The distinction here lies in the third-party review, which suggests an independent examination by parties not directly involved in the audit process. While third-party reviews can be significant in the context of regulatory compliance and external assessments, it doesn’t fit within the typical categorization of audits undertaken regularly by insurers in the same way that the others do. Thus, by identifying this as not a type of audit, the answer accurately reflects the standard classifications used in insurance operations.
