Tennessee Code Title 56. Insurance § 56-41-107

(a) The plan of operation shall provide for the method of underwriting and classifying risks, making and filing rates, adjusting and processing claims, and any other insurance or investment function that is necessary for the purpose of providing essential insurance coverage.

(b) All policies issued by the association shall be subject to a nonprofit group retrospective rating plan to be approved by the commissioner, under which the final premium for all policyholders of the association, as a group, will be equal to the administrative expenses, loss and loss adjustment expenses, plus a reasonable allowance for contingencies and servicing. Policyholders shall be given full credit for all investment income, net of expenses and a reasonable management fee on policyholder supplied funds. Any additional premium resulting from a retrospective adjustment will first be collected from the stabilization fund set forth in § 56-41-108. If these funds are insufficient to pay the entire amount due, the balance will be recouped through surcharges upon policyholders in accordance with a procedure approved by the commissioner.

(c) In providing for the recoupment of deficits that may be incurred by the association, an option shall be offered to an insured each policy year to pay a capital stabilization charge that shall not exceed one hundred percent (100%) of the premium charged to the insurer in that year. The commissioner shall determine the amount of the charge from the appropriate factors of loss experience and risks associated with the plan of operation and the insurer. An insured who pays the stabilization charge shall not be required to pay any assessment to recoup a deficit in the plan incurred in any policy year for which the charge is paid. The plan of operation shall provide for the return to the insured so much of the insured's payment as remains after all actual or potential liabilities under the policy have been discharged.
