Which of the following describes an insurance company that operates solely within Washington state?

A domestic insurance company is one that is incorporated and operates within the same state. In this case, since the insurance company functions solely within Washington state, it fits the definition of a domestic insurer for that state. Domestic insurers are subject to the regulations and laws established by that state’s insurance department, which helps to ensure that they can operate according to local standards and requirements.

In contrast, a foreign insurance company is one that is incorporated in one state but operates in another. An international company generally refers to those that operate in multiple countries, while an alien company is incorporated outside the United States but can do business within it. Therefore, the clear distinction of a domestic insurer aligns with the insurance company’s operations being restricted to Washington state.
