What best defines an alien insurer?

An alien insurer is defined as an insurance company that is incorporated in a foreign country and operates within another country. This term is commonly used to distinguish between different types of insurance companies based on their origin and the jurisdiction in which they are chartered. Alien insurers play a significant role in global insurance markets, allowing for the inclusion of foreign capital and risk-sharing across borders.

In contrast, a company that is incorporated in the same country would be considered a domestic insurer, while a company operating locally could refer to a domestic or potentially a foreign insurer operating in a specific area without implying its incorporation status.
