LDTI comes live in 2023 Starting in 2023, U.S. public life insurers are expected to adopt Accounting Standard Update (ASU) 2018-12, the updated GAAP accounting rules for long-duration contracts. Among various changes required by this accounting update, standardizing the discount rates in long-duration contracts reserving could have implications (or unintended consequences) as life insurers attempt to manage, or mitigate, the reported earnings or book value volatility under this new accounting rule. This issue of Perspectives focuses on how liability discounting could influence life insurers’ enterprise optimization and investment strategy. Life Insurers are expected to navigate accounting, regulatory and rating agencies’ requirements and economic realities when evaluating and optimizing their enterprise values. Sometimes these are not aligned, or even conflicting, and insurers need to understand the trade-offs and choose measures that are most appropriate for their operational needs and stakeholder expectations.
