Missouri Revised Statutes Title XXIV. Business and Financial Institutions § 376.730. Liens, association may impose, when

(1) Impose permanent policy or contract liens in connection with any guarantee, assumption or reinsurance agreement, if the association finds that the amounts which can be assessed under sections 376.715 to 376.758 are less than the amounts needed to assure full and prompt performance of the association's duties under sections 376.715 to 376.758, or that the economic or financial conditions as they affect member insurers are sufficiently adverse to render the imposition of such permanent policy or contract liens, to be in the public interest;

(2) Impose temporary moratoriums or liens on payments of cash values and policy loans, or any other right to withdraw funds held in conjunction with policies or contracts, in addition to any contractual provisions for deferral of cash or policy loan value.
