P.R. Laws tit. 26, § 1215
(1) Every authorized insurer shall annually file with the rating organization of which it is a member or subscriber, or with such other agency as the Commissioner may approve, a statistical report showing a classification schedule of its premiums and losses on all kinds or types of insurance business to which this section is applicable and such other information as the Commissioner may deem necessary or expedient for the administration of the provisions of this chapter. The Commissioner may from time to time prescribe the form of such report including statistical data conforming to established classifications. Such statistical reports shall be consolidated in accordance with regulations prescribed by the Commissioner. 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.
(2) Statistical plans and rules may be promulgated for the recording and reporting of expense experience as to items which are specially applicable to Puerto Rico and are not susceptible of determination by a prorating of expense experience elsewhere.
(3) In the promulgation of statistical plans and rules, the Commissioner shall give consideration to the rating systems on file with him and, in order that such rules and plans may be as uniform as is practicable with those of the several states of the United States, to the rules and to the form of the plans in such states.
