Every insurer which is authorized to do business in this state and which is a member of an insurance holding company system, except a foreign insurer subject to disclosure requirements and standards adopted by statute or regulation in the jurisdiction of its domicile which are substantially similar to those contained in Sections 83-6-3 through 83-6-19, is required to register with the commissioner. Any insurer which is subject to registration under Sections 83-6-3 through 83-6-19 is required to register within sixty (60) days after July 1, 1974, or fifteen (15) days after it becomes subject to registration, whichever is later, unless the commissioner for good cause shown extends the time for registration, and then within such extended time. The commissioner may require any authorized insurer which is a member of a holding company system which is not subject to registration under Sections 83-6-3 through 83-6-19 to furnish a copy of the registration statement or other information filed by such insurer with the insurance regulatory authority of its domiciliary jurisdiction.
