Which of the following is required for a nonadmitted insurer to qualify as a domestic surplus lines insurer?

For a nonadmitted insurer to qualify as a domestic surplus lines insurer in Missouri, it must have at least twenty million dollars in policyholder surplus. This requirement ensures that the insurer has a sufficient financial foundation to support its policy obligations and manage risks effectively. A robust policyholder surplus indicates that the insurer can absorb potential losses, which is especially important in the surplus lines market where coverage is often provided for risks that are more difficult to insure in the standard market.

The requirement for a minimum amount of policyholder surplus serves to protect policyholders by ensuring that the insurer is financially capable of fulfilling its commitments in the event of claims. The twenty million dollar threshold is set as a standard to promote the stability and reliability of domestic surplus lines insurers in the market.

Other options do not meet the criteria of what makes a nonadmitted insurer qualify. For instance, having less than ten million dollars in policyholder surplus would not provide the necessary financial assurance, while being exclusively a marine insurer or operating solely in one jurisdiction does not pertain to the requirements related to capital and financial stability necessary for surplus lines qualification.
