(a) The Commissioner shall promulgate reasonable rules and statistical plans, reasonably adapted to each of the rating systems on file with him or her, which may be modified from time to time and which shall be used hereafter 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 such form and detail as may be necessary to aid him or her in determining whether rating systems comply with the standards set forth in § 2503 of this title. 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.
(b) In promulgating such rules and plans the Commissioner shall give due consideration to the rating systems on file with him or her 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.
(c) The Commissioner may designate 1 or more rating organizations or other agencies to assist him or her in gathering such experience and making compilations thereof, and such compilations shall be made available, subject to reasonable rules promulgated by the Commissioner, to insurers and rating organizations.
(d) Each insurer shall report its loss or expense experience to the lawful rating organization or agency of which it is a member or subscriber but shall not be required to report its loss or expense experience to any rating organization or agency of which it is not a member or subscriber. Any insurer not reporting such experience to a rating organization or other agency may be required to report such experience to the Commissioner. Any report of such experience of any insurer filed with the Commissioner shall be deemed confidential and shall not be revealed by the Commissioner to any other insurer or other person, but the Commissioner may make compilations including such experience.
(e) This section does not apply to property or casualty insurers to the extent it conflicts with any of the provisions of § 526A of this title [repealed].
