(a) Any captive insurance company may provide reinsurance, comprised in section fifteen-a, article four of this chapter, on risks ceded by any other insurer: Provided, That if the reinsurer is licensed as a risk retention group, then the ceding risk retention group or its members must qualify for membership with the reinsurer.

(b) Any captive insurance company may take credit for the reinsurance of risks or portions of risks ceded to reinsurers complying with the provisions of sections fifteen-a and fifteen-b, article four of this chapter. Prior approval of the commissioner shall be required for ceding or taking credit for the reinsurance of risks or portions of risks ceded to reinsurers not complying with sections fifteen-a and fifteen-b, article four of this chapter, except for business written by an alien captive insurance company outside of the United States.

(c) In addition to reinsurers authorized under the provisions of section fifteen, article four of this chapter, a captive insurance company may take credit for the reinsurance of risks or portions of risks ceded to a pool, exchange or association acting as a reinsurer which has been authorized by the commissioner. The commissioner may require any other documents, financial information or other evidence that such a pool, exchange or association will be able to provide adequate security for its financial obligations. The commissioner may deny authorization or impose any limitations on the activities of a reinsurance pool, exchange or association that, in the commissioner's judgment, are necessary and proper to provide adequate security for the ceding captive insurance company and for the protection and consequent benefit of the public at large.

(d) For all purposes of this article, insurance by a captive insurance company of any workers' compensation qualified self-insured plan of its parent and affiliates shall be deemed to be reinsurance.
