Section 742.706 - Renewal; nonrenewal(1) If an insurer offers or purports to renew a commercial liability policy, but on terms less favorable to the insured or at higher rates, the new terms or rates may take effect on the renewal date, if the insurer provides the insured, and the insurance producer if any, 45 days' written notice. If the insurer does not provide such notice, the insured may cancel the renewal policy within 45 days after receipt of the notice or delivery of the renewal policy. Earned premium for the period of time the renewal policy was in force shall be calculated pro rata at the lower of the current or previous year's rate. If the insured accepts the renewal, any premium increase or changes in terms shall be effective immediately following the prior policy's expiration date.(2) Nonrenewal of a commercial liability policy shall not be effective until at least 45 days after the insured receives a written notice of nonrenewal. If, after an insurer provides a notice of nonrenewal as described in this subsection, the insurer extends the policy 90 days or less, an additional notice of nonrenewal is not required with respect to the extension.(3) Subsection (1) of this section does not apply:(a) If the change is a rate, form or plan filed with the Director of the Department of Consumer and Business Services and applicable to the entire line of insurance or class of business to which the policy belongs; or(b) To a premium increase based on the altered nature or extent of the risk insured against.(4) If a commercial liability policy is issued for a term longer than one year, and for additional consideration a premium is guaranteed, the insurer may not refuse to renew the policy or increase the premium for the term of that policy.
