(1)    Assessable to nonassessable. Whenever an assessable mutual accumulates enough surplus to satisfy the financial requirements for the operation of a nonassessable mutual under like conditions, it may apply for a certificate of authority authorizing it to sell nonassessable policies. The commissioner shall issue a certificate of authority designating it a nonassessable mutual if he or she finds that the applicant satisfies the requirements of the law and that the issuance of nonassessable policies will not endanger the interests of its insureds or the public. Policies issued thereafter shall be nonassessable; existing policies shall continue in effect and shall also become nonassessable.

   (2)   Nonassessable to assessable. A nonassessable mutual may apply to the commissioner for a certificate of authority designating it an assessable mutual. The commissioner shall issue the certificate if the law permits such a corporation to issue assessable policies and if he or she finds that the conversion will not endanger the interests of present or future insureds or of the public. All policies issued after conversion shall be assessable, and all policies in effect on the date of conversion shall be assessable except to the extent that there is a contract right then existing not to be assessed.
