Description: With coinsurance of an existing block of long-duration insurance contracts, there may be existing reinsurance that remains in force. The new coinsurance is typically net of such “inuring reinsurance.” In this article, we look at approaches that the new reinsurer might apply to account for the effects of inuring reinsurance.

Description: Adjusting GAAP reinsurance reserves to account for reinsurance protection against the events that trigger direct reserve constraints (such as NPR capping or LFPB flooring) can be a challenge any time. Ceding a block of business that is already in force increases the challenge—especially if one of those constraints was already present at inception of the reinsurance. This article builds on previous work (published in the July 2022 and June 2023 issues) to show how to measure initial reinsurance reserves in a way that complies with AICPA guidance and prepares for effective measurement of subsequent changes in the effects of the constraints.
