(1) Basic factors in rates. Due consideration shall be given to past and prospective loss and expense experience within, and as reasonable and necessary outside this State; to catastrophe hazards; to residual market loss redistributions and other similar obligations, if any; to a reasonable provision for underwriting profit; to contingencies, if any; to trends within and outside this State; to loadings for leveling premium rates over time or for dividends or savings to be allowed or returned by insurers to their policyholders, members, or subscribers; and to all other relevant factors.

(2) Classification. Risks may be classified in any lawful and reasonable way for the collection of statistics and establishment of rates. Rates may be modified for individual risks in accordance with rating plans or schedules which provide for recognition of probable variations in hazards, expenses, or both.

(3) Expenses. The expense provisions included in the rates to be used by an insurer shall reflect the operating methods of the insurer, and, so far as is determinable and reasonable, its own actual and anticipated expense experience for the kind of insurance involved, or any subdivision thereof.

(4) Profits. The rates shall contain an allowance providing for a reasonable profit. In determining the reasonableness of profit, consideration shall be given to all relevant investment income and a provision for contingencies may be included. (Added 1983, No. 238 (Adj. Sess.), § 1; 1987, No. 185 (Adj. Sess.), § 2, eff. May 5, 1988.)
