B-1. Net premium ratio
Under LDTI, the FASB continues to allow use of the net premium ratio (NPR) method at the inception of the policy; however, LDTI introduces changes requiring insurers to recalculate the NPR at least annually over the lifetime of an insurance contract. The following flowchart summarizes the NPR measurement requirement, based on an annual update of cash flow assumptions.
Unit of account, discount rates and updating of assumptions are other key considerations when calculating the NPR under LDTI, discussed below.
B-1.1. Unit of account
LDTI requires insurers to identify the unit of account, also known as the cohort or the level of aggregation, for which the liability for future policy benefits (LFPB) is measured. As with the current GAAP, insurers must group contracts into quarterly or annual cohorts—but under the LDTI, contracts issued in different years cannot be grouped together, reducing complexity. Additionally, LDTI does not have specific grouping requirements for insurance contracts that are onerous, non-onerous or share similar risks.
These changes simplify the financial reporting process, and imply that most insurers’ current approach to determining the unit of account may continue under LDTI. If contracts issued in different years are grouped into the same cohort under the current GAAP, an insurer must redesign the grouping methodology to adhere to the LDTI requirement and reassess the end-to-end business impacts, including disclosures and calculations performed at the group level.
B-1.2. Discount rates
In the current rising interest rate environment, LDTI insurance liabilities are expected to fluctuate more than the liabilities under the current GAAP, which is based on an insurer’s investment portfolio on the contract issue date. The impact of the LDTI discount rate on the LFPB is captured through accumulated other comprehensive income (OCI) on the balance sheet upon transition; changes to subsequent calculations due to changes in the discount rate are recognized in OCI in subsequent periods, while not impacting an insurer’s LDTI profit and loss (P&L). Therefore, it is important for insurers to develop an efficient, repeatable process with a comprehensive controls framework to use the appropriate LDTI discount rates and evaluate financial results for reasonableness periodically.
