No credit will be given the ceding insurer for reinsurance made, ceded, or renewed unless the reinsurance agreements (treaty, facultative or otherwise) substantially provide, or are amended by a supplemental contract to read in substance as follows:
In consideration of the continuing benefits to accrue hereunder to the assuming insurer, the assuming insurer hereby agrees that, as to all reinsurance made, ceded, or renewed the reinsurance shall be payable by the assuming insurer on the basis of the liability of the ceding insurer under the contract or contracts reinsured without diminution because of the insolvency of the ceding insurer
