The purpose of this chapter is to promote the public welfare by regulating insurance rates so that they are not excessive, inadequate, or unfairly discriminatory, and to authorize and regulate limited cooperative action among insurers in ratemaking-related activities and in other matters within the scope of this chapter. Nothing in this chapter is intended to prohibit or discourage reasonable competition, or to prohibit, or encourage except to the extent necessary to accomplish the aforementioned purpose, uniformity in rating systems, rating plans, or practices. This chapter must be liberally interpreted to carry into effect this section. 26.1-25-02. Scope of chapter. 1.

This chapter applies to every insurer, including every stock or mutual company, reciprocal or interinsurance exchange, authorized by any provision of the laws of this state to transact any of the kinds of insurance. However, except with respect to policies issued pursuant to section 26.1-13-15 in any incorporated city with a population over ten thousand, this chapter does not apply to county mutual insurance companies organized under chapter 26.1-13. 3. If any kind of insurance, subdivision, or combination thereof, or type of coverage, subject to this chapter, is also subject to regulation by another rate regulatory act of this state, an insurer to which both acts are otherwise applicable shall file with the commissioner a designation as to which rate regulatory act is applicable to it with respect to the kind of insurance, subdivision, or combination thereof, or type of coverage. 26.1-25-02.1. Definitions. 1. "Advisory organization" means any entity, including its affiliates or subsidiaries, which either has two or more member insurers or is controlled either directly or indirectly by two or more insurers, and which assists insurers in ratemaking-related activities as enumerated in this chapter. Two or more insurers having a common ownership or operating in this state under common management or control constitute a single insurer for purposes of this definition. 2. "Commercial risk" means any kind of risk which is not a personal risk. 3. "Competitive market" means a commercial risk market that has not been found to be noncompetitive as provided for in section 26.1-25-04. All commercial risk markets Page No. 1 except crop hail, farmowners, and medical malpractice insurance are presumed to be competitive. 4. "Developed losses" means losses including loss adjustment expenses, adjusted, using standard actuarial techniques, to eliminate the effect of differences between current payment or reserve estimates and those needed to provide actual ultimate loss including loss adjustment expense payments. 5. "Expenses" means that portion of a rate attributable to acquisition, field supervision, collection expenses, general expenses, taxes, licenses, and fees. 6. "Joint underwriting" means a voluntary arrangement established to provide insurance coverage for a commercial risk pursuant to which two or more insurers jointly contract with the insured at a price and under policy terms agreed upon between the insurers. 7. "Loss trending" means any procedure for projecting developed losses to the average date of loss for the period during which the policies are to be effective. 8. "Noncompetitive market" means the crop hail, farmowners, and medical malpractice insurance markets together with any other line of commercial risk insurance that has not been found by the commissioner to have a reasonable degree of competitiveness within the market considering: a. Market concentration and changes in market concentration determined through the use of the Herfindahl-Hirschman index and the United States department of justice merger guidelines for an unconcentrated market; b. The existence of financial and other barriers that prevent a company from entering the market; c. The number of insurers or groups of affiliated insurers providing coverage in the market; d. The extent to which any insurer or group of affiliated insurers controls the market; e. Whether the total number of companies writing the line of insurance in this state is sufficient to provide multiple insurance options in the market; f. The availability of insurance coverage to consumers in the markets by specific geographic area, by line of insurance, and by class of risk; and g. The opportunities available in the market to acquire pricing and other consumer information. A determination that a market is noncompetitive may not be based solely on the consideration of any one factor. 9. "Personal risk" means homeowners, tenants, private passenger nonfleet automobiles, mobile homes, and other property and casualty insurance for personal, family, or household needs. 10. "Pool" means a voluntary arrangement, established on an ongoing basis, pursuant to which two or more insurers participate in the sharing of risks on a predetermined basis. The pool may operate through an association, syndicate, or other pooling agreement. 11. "Prospective loss costs" means that portion of a rate that does not include provisions for expenses other than loss adjustment expenses, or profit, and are based on historical aggregate losses and loss adjustment expenses adjusted through development to their ultimate value and projected through trending to a future point in time. 12. "Rate" means that cost of insurance per exposure unit whether expressed as a single member or as a prospective loss cost with an adjustment to account for the treatment of expenses, profit, and individual insurer variation in loss experience, prior to any application of individual risk variations based on loss or expense considerations, and does not include minimum premium. 13. "Residual market mechanism" means an arrangement, either voluntary or mandated by law, involving participation by insurers in the equitable apportionment among them of insurance which may be afforded applicants who are unable to obtain insurance through ordinary methods. 14. "Supplementary rating information" includes any manual or plan of rates, classification, rating schedule, minimum premium, policy fee, rating rule, underwriting rule, statistical Page No. 2 plan, and any other similar information needed to determine the applicable rate in effect or to be in effect. 15. "Supporting information" means: a. The experience and judgment of the filer and the experience or date of other insurers or advisory organizations relied upon by the filer; b. The interpretation of any other data relied upon by the filer; and c. Descriptions of methods used in making the rates and any other information required by the commissioner to be filed. 26.1-25-03. Making of rates. 1. Rates must be made in accordance with the following provisions: a. Due consideration must be given to past and prospective loss experience within this state and outside this state to the extent that the consideration is given to areas the commissioner determines are representative of this state, to any conflagration and catastrophe hazards, to a reasonable margin for profit and contingencies, to dividends, savings, or unabsorbed premium deposits allowed or returned by insurers to their policyholders, members, or subscribers, to past and prospective expenses both countrywide, as determined by the commissioner, and those specially applicable to this state, and to all other relevant factors within and outside this state. In the case of fire insurance rates, consideration must be given to the experience of the fire insurance business during a period of not less than the most recent five-year period for which the experience is available. In determining the reasonableness of the profit, consideration may be given to investment income. b. The systems of expense provisions included in the rates for use by any insurer or group of insurers may differ from those of other insurers or group of insurers to reflect the requirements of the operating methods of any such insurer or group with respect to any kind of insurance, or with respect to any subdivision or combination thereof for which subdivision or combination separate expense provisions are applicable. c. Risks may be grouped by classifications for the establishment of rates and minimum premiums. Classification rates may be modified to produce rates for individual risks in accordance with rating plans which establish standards for measuring variations in hazards or expense provisions, or both. The standards may measure any differences among risks that can be demonstrated to have a probable effect upon losses or expense. No risk classification, however, may be based upon race, creed, national origin, or the religion of the insured. d. Rates may not be excessive, inadequate, or unfairly discriminatory.
