Haw. Code R. § 16-23-86
A member may terminate membership in the JUP upon termination of its licensure to transact motor vehicle insurance business in this State. With respect to all policies in effect on the effective date of a member's termination, the liability of the terminating member shall cease on the anniversary date of each policy during the succeeding year. Termination of membership shall not discharge or otherwise affect liabilities incurred prior to the expiration of these policies and the member shall continue to pay assessments until its proportionate share established by its writings prior to discontinuance of business has been determined. However, if the motor vehicle liability, personal injury protection, or physical damage business of an insurer discontinuing the writing of motor vehicle liability, personal injury protection, or physical damage insurance in this State has been purchased by, transferred to, or reinsured by another insurer, the latter shall pay the assessments of the former until the proportionate share of the former as established by its writings prior to such transfer has been paid.
In the event that an insurer is merged with another insurer or there is a consolidation of insurers, the continuing insurer shall pay the assessments of the insurer merged or consolidated. Groups of insurers under the same ownership and management shall be treated as a single insurer under these provisions. Groups of insurers under either the same ownership or management, but not both, may elect to be treated separately.
