If the insurer fails to furnish the renewal terms and the statement of the amount of premium due at least forty-five days prior to the expiration date of the policy, the insurer shall automatically extend the existing policy for a period of forty-five days and the premium for this extended period shall be prorated based on the premium applicable to the existing policy. If the insurer fails to meet the requirements of this section prior to the expiration date of the existing policy, the insurer shall be deemed to have renewed the insured's policy for an identical policy period at the same terms, conditions, and premium as the existing policy.(2) A notice of a decrease in coverage benefits during the term of a policy of insurance identified in subsection (1) of this section shall be valid only if it sets forth the reason for the decrease and is based on one or more of the following reasons:(a) Nonpayment of premium;(b) A false statement knowingly made by the insured on the application for insurance;(c) A substantial change in the exposure or risk other than that indicated in the application and underwritten as of the effective date of the policy unless the insured has notified the insurer of the change and the insurer accepts such change.(3) This section shall not apply to insurance companies authorized to write surplus line insurance in Colorado.L. 86: Entire section added, p. 574, § 6, effective July 1.
