58-40-40. Delegation of rate making and rate filing obligation.
(a) An insurer may itself establish rates based on the factors in G.S. 58-40-25 or it may use rates prepared by a statistical organization, with average expense factors determined by the statistical organization or with such modification for its own expense and loss experience as the credibility of that experience allows.
(b) An insurer may discharge its obligation under G.S. 58-40-30 by giving notice to the Commissioner that it uses rates prepared by a designated statistical organization, with such information about modifications thereof as are necessary to fully inform the Commissioner. The insurer's rates shall be those filed from time to time by the statistical organization, including any amendments thereto as filed, subject, however, to the modifications filed by the insurer.
