Section 379.351 - Approval by director of rules and plans, when - exchange of information with director - director may make rules and regulations1. The director shall approve reasonable rules and statistical plans, reasonably adapted to each of the rating systems on file with him, which may be modified from time to time and which shall be used thereafter by each insurer in the recording and reporting of its loss and countrywide expense experience, in order that the experience of all insurers may be made available at least annually. Such rules and plans may also provide for the recording and reporting of expense experience items which are specially applicable to this state and are not susceptible of determination by a prorating of countrywide expense experience. In approving such rules and plans, the director shall give due consideration to the rating systems on file with him and, in order that such rules and plans may be as uniform as is practicable among the several states, to the rules and to the form of the plans used for such rating systems in other states. No insurer shall be required to record or report its loss experience on a classification basis that is inconsistent with the rating system filed by it. The director may designate rating organizations or other agencies, or both, to assist him in gathering such experience and making compilations thereof, and such compilations shall be made available, subject to reasonable rules approved by the director, to insurers and advisory and rating organizations.2. In order to further uniform administration of rate regulatory laws, the director and every insurer, rating organization, advisory organization or statistical agency may exchange information and experience data with insurance supervisory officials, insurers, rating organizations, advisory organizations or statistical agencies in this and other states, and may consult with them with respect to ratemaking and the application of rating systems.3. The director may make reasonable rules and regulations necessary to effect the purposes of this section.
