Contains a prominent disclaimer that states "This policy is exempt from the filing requirements of section 2236 of the insurance code of 1956, 1956 PA 218, MCL 500.2236." or words that are substantially similar.

If any kind of insurance, subdivision, or combination thereof, or type of coverage, subject to this chapter, is also subject to regulation by another rate regulatory chapter of this act, an insurer to which both chapters are otherwise applicable shall file with the commissioner a designation as to which rate regulatory chapter shall be applicable to it with respect to such kind of insurance, subdivision, or combination thereof, or type of coverage.

If, pursuant to subsection (6), the commissioner certifies the absence of a reasonable degree of competition for a specified classification, type, or kind of insurance, the commissioner may order that each insurer file for prior approval, subject to the provisions of this chapter, any changes to its manuals of classification, manuals of rules and rates, and rating plans the insurer proposes to use for that specified classification, type, or kind of insurance. The order shall state, in writing, the reasons for the commissioner's decision to order the filing. An order issued under this subsection expires 2 years after the date of issuance. If such an order is in effect, rates to which the order applies shall be filed at least 30 days before their proposed effective date. Failure of the commissioner to act within 30 days after submittal constitutes approval.

A determination concerning the existence of a reasonable degree of competition shall take into account a reasonable spectrum of relevant economic tests, including the number of insurers actively engaged in writing the insurance in question, the present availability of that insurance compared to the availability in comparable past periods, the underwriting return of that insurance over a reasonable period of time sufficient to assure reliability in relation to the risk associated with that insurance, and the difficulty encountered by new insurers entering the market in order to compete for the writing of that insurance.
