The commissioner is authorized to request proposals or to negotiate and to enter into contracts with parties which in the judgment of the commissioner are best qualified to provide service to the benefit plans. Contracts entered into are not subject to the requirements of sections 16C.16 to 16C.19. The commissioner may negotiate premium rates and coverage. The commissioner shall consider the cost of the plans, conversion options relating to the contracts, service capabilities, character, financial position, and reputation of the carriers, and any other factors which the commissioner deems appropriate. Each benefit contract must be for a uniform term of at least one year, but may be made automatically renewable from term to term in the absence of notice of termination by either party.
