Conn. Gen. Stat. § 38a-1004: Duration and termination of certificate of approval.

(a) The certificate of approval issued by the commissioner to a workers' compensation self-insurance group shall authorize the group to provide workers' compensation benefits. The certificate of approval shall remain in effect until terminated at the request of the group or revoked by the commissioner, pursuant to the provisions of section 38a-1021, or any other provision of this title.

(b) The commissioner shall not grant the request of any group to terminate its certificate of approval unless such group has insured or reinsured all incurred workers' compensation obligations with an authorized insurer under an agreement filed with and approved, in writing, by the commissioner. Such obligations shall include both known claims and expenses associated therewith and claims incurred but not reported and expenses associated therewith.

(c) Subject to the approval of the commissioner, any group may merge with another group engaged in the same or similar type of business only if the resulting group assumes in full all obligations of the merging groups. The commissioner may hold a hearing on the merger and shall do so if any party, including any member of any of the merging groups, requests it.
