(a) For purposes of this section, an "assumption reinsurance agreement" means any contract which:

1. (1) Transfers insurance obligations and/or risks of existing or in-force contracts of insurance from a transferring insurer to an assuming insurer; and
2. (2) Is intended to effect a novation of the transferred contract of insurance with the result that the assuming insurer becomes directly liable to the policyholders of the transferring insurer and the transferring insurer's insurance obligations and/or risks under the contracts are extinguished.

(c) Credit for reinsurance shall be governed by the provisions of sections fifteen-a and fifteen-b of this article.

1. (1) No credit shall be allowed, as an admitted asset or deduction from liability, to any ceding insurer for reinsurance, unless the reinsurance contract provides, in substance, that in the event of the insolvency of the ceding insurer, the reinsurance shall be payable under a contract reinsured by the assuming insurer on the basis of reported claims allowed by the liquidation court, without diminution because of the insolvency of the ceding insurer. Payments shall be made directly to the ceding insurer or to its domiciliary liquidator except:

   1. (A) Where the contract or other written agreement specifically provides another payee of the reinsurance in the event of the insolvency of the ceding insurer; or (B) where the assuming insurer, with the consent of the direct insured, has assumed the policy obligations of the ceding insurer as direct obligations of the assuming insurer to the payees under the policies and in substitution for the obligations of the ceding insurer to payees.
2. (2) The reinsurance agreement may provide that the domiciliary liquidator of an insolvent ceding insurer shall give written notice to the assuming insurer of the pendency of a claim against the ceding insurer on the contract reinsured within a reasonable time after the claim is filed in the liquidation proceeding. During the pendency of the claim, any assuming insurer may investigate the claim and interpose, at its own expense, in the proceeding where the claim is to be adjudicated any defenses which it deems available to the ceding insurer or its liquidator. The expense may be filed as a claim against the insolvent ceding insurer to the extent of a proportionate share of the benefit which may accrue to the ceding insurer solely as a result of the defense undertaken by the assuming insurer. Where two or more assuming insurers are involved in the same claim and a majority in interest elect to interpose a defense to the claim, the expense shall be apportioned in accordance with the terms of the reinsurance agreement as though the expense had been incurred by the ceding insurer.
