What is an "alien insurer"?

An "alien insurer" is defined as an insurance company that is incorporated or organized under the laws of a country other than the one in which it is operating. This means that if an insurer is admitted and conducting business in New Hampshire but is established in another country, it qualifies as an alien insurer. The significance of this designation lies in regulatory aspects, as alien insurers are often subject to specific rules and requirements that differ from domestic insurers—those incorporated within the same country or state.

The other definitions do not accurately describe what an alien insurer is. An insurer that operates solely within a country would be classified as a domestic insurer, not falling under the "alien" category. A company based in multiple states wouldn't fit the definition, either; it would generally be referred to as a multi-state insurer or a regional insurer, depending on its operations. Insurers dealing exclusively in surplus lines would be categorized based on their market segment, which again does not capture the essence of an alien insurer. Thus, the correct answer highlights the international aspect of the insurer's operations.
