(a) A plan that desires to cease existence shall apply to the Commissioner for authority to dissolve. Applications to dissolve must be on forms prescribed by the Commissioner and must be approved or disapproved by the Commissioner within 60 days of receipt. Dissolution without authorization is prohibited and does not absolve a plan or its participants from fulfilling the plan's continuing obligations. An application to dissolve must be granted if either of the following conditions is met:

(1) The plan demonstrates that it has no outstanding liabilities, including incurred but not reported liabilities; or

(2) The plan has obtained an irrevocable commitment from a licensed insurer which provides for payment of all outstanding liabilities and for providing all related services, including payment of claims, preparation of reports, and administration of transactions associated with the period when the plan provided coverage.

(b) Upon dissolution, after payment of all outstanding liabilities and indebtedness, the assets of the plan must be distributed to all employers participating in the plan during the last five years immediately preceding dissolution. The distributive share of each employer must be in the proportion that all contributions made by the employer during such five-year period bear to the total contributions made by all participating employers during such five-year period.
