What do we call an insurance company that meets the legal and financial requirements to operate in a specific state?

An insurance company that meets the legal and financial requirements to operate in a specific state is referred to as an admitted insurer. These companies are authorized by the state's insurance department, which means they have fulfilled the necessary regulatory obligations, such as maintaining adequate capital reserves and adhering to state laws. This designation is significant because it gives the insurer the authority to conduct business within the state, and it also provides certain protections to policyholders, such as eligibility for the state's guarantee fund in the event of the insurer's insolvency.

In contrast, non-admitted insurers operate without such state approval, which can lead to greater risks for consumers because they are not protected by state guarantee funds. An ASO plan (Administrative Services Only) refers to arrangements where an employer self-funds benefits but hires a third party to manage the plan, and this is not a type of insurer. Adverse insurer is not a standard term used in the insurance industry and does not denote a recognized category of insurers. Therefore, the classification of an insurance company as an admitted insurer is integral to understanding its legitimacy and operational capacity within a state.
