How Insurance Contract Liabilities Are Reported under IFRS 17 and ASC 944/ASU 2018-12

Insurance accounting has diverged significantly between IFRS and US GAAP. IFRS 17 introduces a unified, current-value framework centered on fulfilment cash flows and a locked-in contractual service margin (CSM). US GAAP retains ASC 944, but the LDTI amendments (ASU 2018-12) modernize long-duration contracts with updated discounting, unlocking of assumptions, fair value for market risk benefits, and simplified DAC amortization.

Both aim to improve transparency about the timing, uncertainty, and drivers of insurer profitability—separating service results from financial effects (discount rates and investment markets).

How liabilities are measured under IFRS 17

General Measurement Model (GMM / Building Block Approach)Insurance contract liability = Fulfilment cash flows (FCF) + Contractual Service Margin (CSM).

• FCF = unbiased, probability-weighted estimates of future cash inflows/outflows, discounted using current, top-down or bottom-up rates consistent with the cash flow characteristics, plus explicit risk adjustment for non-financial risk.

• CSM = unearned profit at initial recognition; no day-1 gain. It is recognized in profit or loss as service is provided (systematically over coverage units).

Premium Allocation Approach (PAA)A simplified model permitted for short-duration contracts (similar to unearned premium), with liability for remaining coverage measured largely at unearned premium less acquisition cash flows.

Onerous contractsIf FCF + CSM < 0 at initial recognition or subsequent measurement, loss is recognized immediately; CSM is set to zero.

Discount rate & OCIEntities may present the finance income/expense effect of discount rate changes in profit or loss or split with OCI (policy choice by portfolio).

How liabilities are measured under US GAAP (ASC 944 with LDTI)

Long-duration contracts (traditional life, limited-payment, UL with guarantees):

• Cash flow assumptions (mortality, lapses, expenses) are reviewed at least annually and updated with a catch-up recorded in earnings (prospective unlocking).

• Discount rate for liability measurement is a current, upper-medium grade fixed-income yield (A-grade). Rate updates flow through OCI, while assumption changes (non-discount) go to P&L.

• DAC (deferred acquisition costs) amortized on a constant-level basis over expected term (no longer linked to gross profits).

• Market Risk Benefits (MRB) (e.g., features in variable annuities) are measured at fair value through earnings, with non-performance risk (own credit) in OCI.

Short-duration contractsUnearned premium model continues; claim liabilities use undiscounted or discounted estimates where permitted; disclosures are enhanced.

Side-by-side: key differences

Topic	IFRS 17	US GAAP (ASC 944 / LDTI)
Measurement objective	Present value fulfilment cash flows + risk adjustment + CSM	Net premium reserve with updated assumptions; discount at A-grade current yield; MRB at fair value
Profit deferral	CSM (locked-in at inception, released by coverage units)	No CSM; earnings reflect unlocking and DAC pattern
Risk adjustment	Explicit non-financial risk margin	No explicit risk adjustment in liability
Onerous contracts	Immediate loss; loss component tracked	Loss recognition via unlocking; no separate loss component concept
Discount rate presentation	P&L or split with OCI by policy	OCI for discount changes (long-duration)
Acquisition cash flows	Capitalize as asset; allocate to groups; amortize via CSM/PAA	DAC amortized on constant-level basis; impair if unrecoverable
Market-linked guarantees	Within liability using current estimates; optional OCI policy	MRB at fair value through earnings; own credit in OCI
Unit of account	Groups of contracts by annual cohorts & profitability	Product cohorting; no IFRS-style annual cohort requirement

Recognition patterns and performance reporting

IFRS 17 statement of profit or loss separates:

• Insurance service result = insurance revenue – insurance service expenses (includes CSM release and risk adjustment release).

• Insurance finance result = effects of discounting and financial risks (P&L or OCI split).

US GAAP (LDTI) presents:

• Benefits, claims, and other changes driven by unlocking;

• Net investment income;

• OCI for discount updates;

• Fair value changes of MRB in earnings.

The IFRS 17 service result is more margin-centric, while GAAP emphasizes assumption unlocking and MRB fair value effects.

Worked examples (simplified)

IFRS 17 — initial recognition (GMM)Best-estimate future outflows (claims/expenses) PV = 9,400Best-estimate inflows (premiums) PV = 10,000→ FCF (pre-risk) = +600Risk adjustment = (200)→ Net FCF = +400CSM = 400 (to eliminate day-1 gain)Insurance contract liability at inception = FCF (−400) + CSM (−400) = −800 (a liability of 800).

Entries (illustrative):

• Dr Insurance contract asset (premiums receivable) 10,000

• Cr Insurance contract liability – FCF 9,400

• Cr Insurance contract liability – CSM 400

  
  

  (Alternative presentations exist depending on systems and cash settlement timing.)

Subsequent period:

• Recognize service expense for actual/expected claims, release risk adjustment, and CSM by coverage units.

• Record finance income/expense from discount unwinding and rate changes (P&L/OCI).

US GAAP — long-duration (post-LDTI)Beginning liability (net premium reserve) = 8,900 (using locked assumptions and A-grade curve)Year-end review: mortality worsens; present value of future benefits increases by 300 → catch-up loss in P&L.Discount rate declines: present value rises by 200 → OCI loss 200.

Entries (illustrative):

• Dr Change in insurance liability (P&L) 300

• Cr Future policy benefits 300

• Dr OCI 200

• Cr Future policy benefits 200

MRB fair value increase 150 due to equity volatility → P&L loss 150.

Acquisition cash flows and DAC / IAC

IFRS 17

• Insurance acquisition cash flows (IAC) capitalized (even before contract inception when directly attributable), allocated to groups, and amortized by expected coverage units; impairment if groups become onerous.

US GAAP

• DAC capitalized and amortized on a constant-level basis over expected term; subject to recoverability testing (no EGP/GP links).

Illustrative entry (GAAP):

• Dr DAC 1,000

• Cr Cash 1,000

• Dr Amortization expense 100

• Cr DAC 100

Illustrative entry (IFRS):

• Dr Insurance acquisition asset 1,000

• Cr Cash 1,000

• Dr Insurance service expense (IAC amortization) 120

• Cr Insurance acquisition asset 120

Disclosures that analysts scrutinize

IFRS 17 requires reconciliations (roll-forwards) for:

• Liability for remaining coverage and liability for incurred claims;

• CSM movements (new business, interest accretion, releases, changes in estimates);

• Risk adjustment changes and confidence-level disclosure or technique.

  
  

  Sensitivity to discount and non-financial risk is expected.

US GAAP (LDTI) enhances:

• Disaggregated roll-forwards of liability for future policy benefits;

• Discount rate used and OCI impacts;

• Assumption updates (mortality, lapses, expenses);

• MRB fair value methods and inputs;

• DAC activity and amortization.

Example IFRS 17 CSM roll-forward (USD):

Movement	Amount
Opening CSM	2,400
New business added	600
Interest accretion on CSM	90
Changes in FCF related to future service	(120)
Release to revenue (coverage units)	(350)
Closing CSM	2,620

Impact on financial performance and ratios

• Earnings profile: IFRS 17 releases CSM over coverage units → smoother service margins; GAAP earnings reflect assumption unlocking and MRB volatility.

• Equity/OCI: Discount rate movements drive OCI under both (policy choice under IFRS 17; required for GAAP discount updates and MRB own-credit).

• Return metrics: IFRS 17 may show higher contractual service margin asset/liability balances; GAAP may show larger OCI swings and fair value effects for MRB.

• Capital ratios: Different measurement bases affect solvency metrics; analysts reconcile to regulatory capital frameworks (e.g., RBC, Solvency II).

·····

.....

Operational considerations

• Build granular cohorts (IFRS 17 annual cohorts by profitability groups) and robust data pipelines for cash flows, coverage units, and RA.

• Establish discount curves: IFRS 17 (top-down/bottom-up) vs GAAP A-grade curve; document methodology and governance.

• Integrate actuarial models with the ledger for CSM engines (IFRS 17) and LDTI unlocking schedules (GAAP).

• Enhance controls and audit trail over assumption updates, MRB fair value inputs, and OCI policies.

• Align KPIs (e.g., CSM, new business strain, insurance service result) to investor communications.

A disciplined implementation of IFRS 17 and LDTI elevates insight into insurers’ sources of profit, separating underwriting performance from market movements and providing more comparable, decision-useful information.
