A. 1. No credit shall be allowed, as an admitted asset or as a deduction from liability, to any ceding insurer for reinsurance nor increase the amount it is authorized to have at risk 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 or contracts 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. Such payments shall be made directly to the ceding insurer or to its domiciliary liquidator, except:

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 such ceding insurer on the contract reinsured within a reasonable time after such claim is filed in the liquidation proceeding. During the pendency of such claim, any assuming insurer may investigate such claim and interpose, at its own expense, in the proceeding where such claim is to be adjudicated, any defenses which it deems available to the ceding insurer, or its liquidator. Such 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. If two or more assuming insurers are involved in the same claim and a majority in interest elect to interpose one or more defenses to such claim, the expense shall be apportioned in accordance with the terms of the reinsurance agreement as though such expense had been incurred by the ceding insurer.
