REINSURANCE REINSURANCE
Allowance for Credit Losses – Reinsurance Receivables

The Company establishes an allowance for current expected credit losses related to amounts receivable from reinsurers (the “Reinsurance ACL”). Changes in the Reinsurance ACL are recognized as a component of benefits and settlement expenses. The Reinsurance ACL is remeasured on a quarterly basis using an internally developed probability of default (“PD”) and loss given default (“LGD”) model. Key inputs to the calculation are a conditional probability of insurer liquidation by issuer credit rating and exposure at default derived from a runoff projection of ceded reserves by reinsurer to forecast future loss amounts. Management’s position is that the rate of return implicit in the financial asset (i.e. the ceded reserves) is associated with the discount rate used to value the underlying insurance reserves; that is, the rate of return on the asset portfolio(s) supporting the reserves. For reinsurance receivable exposures that do not share similar risk characteristics with other receivables, including those associated with counterparties that have experienced significant credit deterioration, the Company measures the allowance for credit losses individually, based on facts and circumstances associated with the specific reinsurer or transaction.
As of March 31, 2021 and December 31, 2020, the Reinsurance ACL was $90 million and $94 million respectively. There were no write-offs or recoveries during the three months ended March 31, 2021 and 2020.
The Company had total reinsurance receivables of $4.6 billion as of March 31, 2021, which includes both ceded policy benefit reserves and receivables for claims. Receivables for claims represented 13% of total reinsurance receivables as of March 31, 2021. Receivables for claims are short-term in nature, and generally carry minimal credit risk. Of reserves ceded as of March 31, 2021, 76% were receivables from reinsurers rated by A.M. Best Company. Of the total rated by A.M. Best, 75% were rated A+ or better, 13% were rated A, and 11% were rated A- or lower. The Company monitors the concentration of credit risk the Company has with any reinsurer, as well as the financial condition of its reinsurers, on an ongoing basis. Certain of the Company’s reinsurance receivables are supported by letters of credit, funds held or trust agreements.
