Idaho Statutes Title 41. Insurance § 41-1606. Rate filings required

(1) There shall be filed with the director on behalf of every insurer writing workmen's compensation coverages in this state, every manual of classifications, rules and rates, every rating plan and every modification of any of the foregoing which it proposes to use. Every such filing shall state the proposed effective date thereof, and shall indicate the character and extent of the coverage contemplated. When a filing is not accompanied by the information upon which the filing is supported, and the director does not have sufficient information to determine whether such filing meets the requirements of this chapter, he shall require the insurer's rating organization or the insurer to furnish the information upon which it supports the filing and in such event the waiting period shall commence as of the date such information is furnished. The information furnished in support of a filing may include (a) the experience or judgment of the insurer, (b) the insurer's or rating organization's interpretation of any statistical data relied upon, (c) the experience of other insurers or rating organizations, or (d) any other relevant factors.

(2) A filing and any supporting information shall be open to public inspection after the filing becomes effective.
