South Carolina and Tennessee updated their respective credit for reinsurance statutes consistent with NAIC Credit for Reinsurance Model Law 785. Idaho and Tennessee adopted the NAIC Credit for Reinsurance Model Regulation 786. Among other changes, the updated model law and regulation set incremental collateral requirements for reinsurance ceded to alien reinsurers in order for a cedent to recognize a reduction in its liabilities for the amount ceded. Previously, the reinsurance ceded to alien reinsurers was required to be secured by 100% collateral.
