With regard to each insurer qualified to transact only the business of reinsuring credit life and credit accident and credit health insurance, the commissioner shall collect a nonrefundable annual regulatory fee of three thousand dollars ($3,000). One half (1/2) of the regulatory fee shall be collected on April 1, which, notwithstanding § 56-1-501, shall also be the date on or before which the insurer’s annual statement shall be filed, and the balance shall be collected on September 1 of each year, except that the initial regulatory fee collected shall be reduced pro rata to reflect the number of months during the year in which the certificate of authority has been in effect. The regulatory fees paid into the department under this section shall be held by the commissioner as expendable receipts for the purpose of administering chapter 7, part 9 of this title.
