What criteria must regulated aliens fulfill according to the IID?

Regulated aliens must meet specific criteria established by the Insurance Information Department (IID) to ensure they operate within a sound financial framework and uphold acceptable underwriting standards. The emphasis on capital and/or surplus indicates that these companies must maintain a sufficient financial buffer to cover potential claims, ensuring their solvency and ability to honor policyholder obligations. Financial integrity reflects the overall financial health of the entity, which impacts its reliability in the market. Underwriting practices are critical as they dictate how risks are assessed and priced, directly influencing the insurer's sustainability and adherence to regulatory requirements. Therefore, meeting these standards helps protect policyholders and maintains stability within the insurance market.

The other options focus on facets like dividends, market share, advertising, and sales volume, which, while relevant to the broader business operations, do not address the regulatory criteria that ensure financial viability and responsible underwriting practices.
