After the policy has been in effect for 60 days, no such policy shall be canceled by the insurer except when there has been a material misstatement, a nonpayment of premium, a failure to comply with underwriting requirements established by the insurer within 60 days of the date of effectuation of coverage, or a substantial change in the risk covered by the policy or when the cancellation is for all insureds under such policies for a given class of insureds. This subsection does not apply to individually rated risks having a policy term of less than 90 days.
