Montana Title 33. Insurance and Insurance Companies § 33-16-202. Recording and reporting of loss and expense experience

(1) The commissioner may promulgate and may modify reasonable rules and statistical plans, reasonably adapted to each of the rating systems used, which must be used 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 in form and detail as necessary to aid the commissioner in determining whether rates comply with the applicable standards of this chapter. The rules and plans may also provide for the recording and reporting of expense experience items that are specially applicable to this state and are not susceptible of determination by a prorating of countrywide expense experience.

(2) In promulgating rules and plans, the commissioner shall give consideration to the rating systems in use in this state and, in order that the 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 rating systems in other states. An insurer may not be required to record or report its loss experience on a classification basis that is inconsistent with the rating system used by it.

(3) The commissioner may designate one or more rating organizations or other agencies to assist in gathering and making compilations of loss and expense experience, and the compilations must be made available, subject to reasonable rules promulgated by the commissioner, to insurers and rating organizations.
