Any insurer that is subject to registration under this section shall register within 30 days after it becomes subject to registration, and an amendment to the registration statement shall be filed by April 1 of each year for the previous calendar year; unless the Commissioner for good cause shown extends the time for registration or filing, and then within the extended time. All registration statements shall contain a summary, on a Form C as prescribed by the Commissioner, outlining all items in the current registration statement representing changes from the prior registration statement. The Commissioner may require any insurer that is an insurance member of a holding company system that is not subject to registration under this section to furnish a copy of the registration statement or other information filed by the insurance company with the insurance regulator of its domiciliary jurisdiction.
The question of whether the filing insurer is the principal insurance company in the insurance holding company system is a question of fact, and an insurer filing a registration statement or report in lieu of Form B on behalf of an affiliated insurer shall set forth a brief statement of facts which will substantiate the filing insurer's claim that it, in fact, is the principal insurer in the insurance holding company system.
