Each registered insurer shall keep current the information required to be disclosed in its registration statement by reporting all material changes or additions within 15 days after the end of the month in which it learns of each such change or addition. Any insurer which is subject to registration under this section shall register within 15 days after it becomes subject to registration, and annually thereafter by June 1 of each year for the previous calendar year, unless the Commissioner for good cause shown extends the time for registration, and then within such extended time. The Commissioner may require any insurer authorized to do business in the State which is a member of a holding company system, and which is not subject to registration under this section, to furnish a copy of the registration statement, the summary specified in subsection (c) of this section or other information filed by such insurance company with the insurance regulatory authority of domiciliary jurisdiction.
