Regulation named after a former Superintendent of Insurance of New York State, and instituted in the early 1900s. It requires every insurer admitted to New York to comply with the New York Insurance Code and even in other states where that insurer does business. This rule has had a nationwide impact on the insurance industry. New York State is known for its leadership role in insurance regulation. Thus, if an insurance company is admitted to conduct business in New York, it is a sign that it has met exacting requirements.
