(1) (a) A member insurer may offset against its premium tax liability to this state that amount of its class B assessment described in section 10-20-109 that was assessed for the association's life and annuity accounts pursuant to section 10-20-106 to the extent of twenty percent of the amount of such assessment for each of the first, second, third, fourth, and fifth calendar years following the year in which such assessment was paid.

(b) To the extent the offsets specified in paragraph (a) of this subsection (1) exceed the member insurer's premium tax liability, they may be carried forward to offset premium tax liabilities in future years. In the event a member insurer should cease doing business, all uncredited assessments may be credited against its premium tax liability for the year it ceases doing business.

(c) In no event shall the total amount of all such offsets for all member insurers exceed four million dollars in any year. The association shall prorate the amount of such offset among all member insurers if the total amount of offset would otherwise exceed four million dollars in any such year and shall notify each insurer of the maximum amount of offset allowable for that year and the amount of the excess offset, if any, that may be carried forward to future years.

(d)

(I) Each member insurer writing health insurance is required to recoup over a reasonable length of time a sum reasonably calculated to recoup the assessments paid by the member insurer under this article by way of a surcharge on premiums charged for health insurance policies to which this article applies. Amounts recouped shall not be considered premiums for any other purpose, including the computation of gross premium tax or agent's commission.

(II) The amount of the surcharge shall be filed as part of an insurer's rate filing pursuant to section 10-16-107 (1). Such surcharge must be shown in the rate filing as a separate component of the rate and shall include supporting documentation.

(III) Such member insurers who collect surcharges in excess of assessments paid pursuant to this article for an insolvent insurer shall remit the excess to the association as an additional assessment within one hundred twenty days after the end of the collection period as determined by the association. The excess shall be applied to reduce future assessments for that insurer in the appropriate category.

(IV) Any such member insurer may omit the collection of the surcharge in any year from its insureds when the expense of collecting the surcharge in any such year would exceed the amount of the surcharge. However, nothing in this paragraph (d) shall relieve the member insurer of its ultimate obligation to recoup the amount of the surcharge otherwise collectible from any such previous year.

(2) Any sums which are acquired by refund pursuant to section 10-20-109 (6) from the association by member insurers, and which have theretofore been offset against premium taxes as provided in subsection (1) of this section, shall be paid by such insurers to this state in such manner as the tax authorities may require. The association shall notify the commissioner that such payments have been made.
