Iowa Code Title XIII. Commerce [Chs. 505-554D] § 515A.13. Rate administration

1. The commissioner shall promulgate reasonable rules and statistical plans, reasonably adapted to each of the rating systems on file with the commissioner, 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 in such form and detail as may be necessary to aid the commissioner in determining whether rating systems comply with the standards set forth in section 515A.3. 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 countywide expense experience. In promulgating such rules and plans, the commissioner shall give due consideration to the rating systems on file 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 commissioner may designate one or more rating organizations or other agencies to assist 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.

2. Reasonable rules and plans may be promulgated by the commissioner for the interchange of data necessary for the application of rating plans.

3. In order to further uniform administration of rate regulatory laws, the commissioner and every insurer and rating organization may exchange information and experience data with insurance supervisory officials, insurers, and rating organizations in other states and may consult with them with respect to rate making and the application of rating systems.

4. The commissioner may make reasonable rules necessary to effect the purposes of this chapter.

5. A person other than the commissioner or the commissioner's designee shall not release to another person, other than to the servicing insurer of the policy or to the commissioner or the commissioner's designee, experience, payroll, loss data, expiration date of a policy, or classification information without the prior written approval of the policyholder. A violation of this section shall be considered an unfair trade practice pursuant to chapter 507B.
