Section 2 — IFRS 17 ↔ ASC 944 LDTI differences

[T1] See ifrs-local-gaap-reconciliation.md for foundation. Insurance-specific:

IFRS 17 vs ASC 944 LDTI differences (Section 2 — IFRS 17 ↔ ASC 944 LDTI differences)

Topic	IFRS 17	ASC 944 LDTI
Liability measurement	Building Block Approach (BBA), Premium Allocation Approach (PAA) for short-duration, Variable Fee Approach (VFA) for direct participating	Net premium reserve; updated assumptions through P&L (LDTI improvements)
Discount rate	Top-down or bottom-up; reflects characteristics of cash flows	Single A-quality corporate yield curve (LDTI prescribed)
Contractual Service Margin (CSM)	Recognised in P&L over coverage period	No equivalent — gain at issue spread differently
Risk Adjustment	Reflects compensation for non-financial risk; entity-specific	Different — discretion in net premium reserve methodology
Onerous contract	Loss recognised immediately + Loss Component tracking	Premium Deficiency Reserve (PDR) at portfolio level
Reinsurance held	Asset/liability separately; expected to mirror underlying when treaty matches	Recognised as reduction of net premium

• Material tax interaction — IFRS 17 CSM creates a deferred tax balance — the CSM is recognised in equity at transition but released to P&L over time. Deferred tax tracks this release. ([T1] Material tax interaction)
