C.R.S. § 10-4-405: Filing of rating information - certain coverages - rules.

(1) With respect to type I kinds of insurance as defined in section 10-4-401 (3)(a), every insurer shall file with the commissioner every manual of classifications, rules, and rates, every rating plan, and every modification of any of the foregoing which it proposes to use in this state.

(1.2) No sooner than January 1, 2027, and upon the commissioner adopting rules, an insurer offering multiperil homeowner's insurance for property or risks located in the state shall submit an annual filing to the commissioner. The annual filing must include an exhibit reporting:

(a) The number of policies in force;

(b) The number of homes that have installed a resilient roof system;

(c) The discount applied to homes due to the presence of a resilient roof system; and

(d) The wind and hail claims frequency and severity for homes with and without a resilient roof system.

(2) (a) Every filing shall state the proposed effective date thereof and shall indicate the character and extent of the coverage contemplated. Filings regarding workers' compensation insurance rates shall be filed on or before August 1 of any calendar year. When a filing is not accompanied by the information upon which the insurer supports the filing and the commissioner does not have sufficient information to determine whether the filing meets the requirements of this part 4, he shall, within fifteen days after the date of filing, require the insurer to furnish the information upon which it supports the filing, and in such event the waiting period provided for in section 10-4-406 (2) shall commence as of the date such information is furnished.

(b) The information furnished in support of a filing may include: The experience or judgment of the insurer or rating organization making the filing; its interpretation of any statistical data it relied upon; the experience of other insurers or rating organizations; or any other factors which the insurer or rating organization deems relevant.

(3) A filing and any supporting information shall be open to public inspection at the division of insurance.

(4) An insurer may satisfy its obligation to make such filings by becoming a member of, or a subscriber to, a licensed rating organization which makes such filings and by authorizing the commissioner to accept such filings in its behalf; but nothing contained in this title shall be construed as requiring any insurer to become a member of, or a subscriber to, any rating organization.

(5) Upon the written application of the insured, stating his reasons therefor, filed with and approved by the commissioner, a rate in excess of that provided by filing, otherwise applicable, may be used on any specific risk, and such application shall not be subject to any of the provisions of section 10-4-406.
