(2) When the reason for cancellation does not accompany or is not included in the notice of cancellation, the insurer shall, upon written request of the named insured mailed or delivered to the insurer not less than fifteen days prior to the effective date of cancellation, specify in writing the reason for such cancellation. Such reason shall be mailed or delivered to the named insured within five days after receipt of such request.
(3) This section shall not apply to nonrenewal of a policy.
(4) This section shall not apply to insurers providing coverage for exempt commercial policyholders, as defined pursuant to section 10-4-1402 and rules adopted by the commissioner pursuant to that section.
