Which of the following is NOT required to have a Certificate of Authority?

A Certificate of Authority is a formal license that allows an insurance company to operate within a specific state. It is required for most insurance transactions to ensure that the company meets regulatory standards and operates within the law.

Standard auto insurance policies fall under state-regulated insurance lines, meaning companies offering these policies are typically required to obtain a Certificate of Authority. This oversight ensures that they comply with state laws regarding insurance, protecting consumers by establishing a framework of accountability.

In contrast, certain transactions, like group life coverage, may operate under different regulatory frameworks. Investigations related to past claims often pertain to compliance activities rather than direct transactions requiring a Certificate. Excess liability insurance may also involve specific regulatory conditions that differ from standard line regulations. Therefore, standard auto insurance policies do indeed require a Certificate of Authority, distinguishing them from the other options presented.
