LDTI and Reinsurance: How Targeted Improvements Change Ceded Life Accounting
Last reviewed: November 2026
LDTI reinsurance accounting is how US GAAP insurers measure ceded and assumed long-duration reinsurance under ASU 2018-12, the FASB's Targeted Improvements to the Accounting for Long-Duration Contracts. Because reinsurance recoverables must be measured consistently with the reinsured liabilities, every change LDTI made to direct liabilities flows through to ceded life reinsurance.
The result is new volatility in places where reinsurance used to look neutral. Discount rate mechanics, assumption updates and cohort data can all leave a fully reinsured block with a visible earnings or OCI effect.
This guide is for CFOs, chief actuaries, heads of reinsurance accounting and life reinsurance teams. It is general information, not accounting advice, so take professional advice on your own treaties and audit position.
Key Takeaways
- LDTI (ASU 2018-12) is effective for large SEC filers from fiscal years beginning after 15 December 2022, and for all others after 15 December 2024.
- ASC 944 requires reinsurance recoverables to be measured consistently with the reinsured liabilities, so LDTI changes reach ceded business automatically.
- The upper-medium grade discount rate is updated each reporting date, with remeasurement in OCI and interest accretion at a locked-in rate.
- A fully reinsured block can still show net income and OCI effects when the direct and ceded locked-in rates differ.
- The cost of reinsurance is deferred and amortised, and no gain is recognised at inception.
- Disclosures show liabilities gross of reinsurance, with recoverables reconciled separately.
What Is LDTI?
LDTI is the FASB's package of changes to Topic 944 for long-duration insurance contracts, issued in August 2018 as ASU 2018-12. According to the ASU 2018-12 summary, it changed five main areas.
| Area | What LDTI Requires |
|---|---|
| Liability for future policy benefits | Review cash flow assumptions at least annually, with changes recognised in net income |
| Discount rate | Upper-medium grade (low-credit-risk) fixed-income yield, updated each reporting date, with the change recognised in OCI |
| Provisions for adverse deviation and loss recognition | Eliminated for traditional and limited-payment contracts |
| Market risk benefits | Measured at fair value, with own credit changes in OCI |
| Deferred acquisition costs | Amortised on a constant level basis, with no impairment test |
| Disclosures | Disaggregated rollforwards and disclosure of significant inputs, judgements and assumptions |
When Did LDTI Become Effective?
ASU 2020-11 set the current effective dates. For public business entities that are SEC filers and not smaller reporting companies, LDTI applies to fiscal years beginning after 15 December 2022.
For all other entities, it applies to fiscal years beginning after 15 December 2024, and to interim periods within fiscal years beginning after 15 December 2025. That means many mutuals, private insurers and smaller reporting companies are in their first or second LDTI cycle now.
How Does LDTI Change Ceded Reinsurance Accounting?
LDTI did not write a new reinsurance model. Instead, ASC 944-40-25-34 already required reinsurance recoverables to be recognised consistently with the reinsured liabilities, using consistent assumptions.
So when the direct liability changed, the recoverable had to change with it. Four effects matter most for cedents.
Cash Flow Assumptions Must Match
The recoverable must use mortality, morbidity, lapse and expense assumptions consistent with the direct contracts. When the direct assumptions are unlocked, the recoverable is updated at the same time.
The net premium ratio approach with retrospective catch-up then applies on both sides. If the recoverable mirrors the direct model, assumption changes largely offset in net income for the reinsured share.
Discount Rates Split Income and OCI
The direct liability and the recoverable are both remeasured at the current upper-medium grade rate on the balance sheet. Interest accretion in net income, however, uses a locked-in rate.
For prospective treaties covering new business, the recoverable generally uses the same locked-in rates as the direct contracts it covers. For treaties covering in-force blocks, common practice uses the yield curve at the reinsurance date as the recoverable's locked-in rate, which differs from the older direct rate.
Cost of Reinsurance Is Deferred
The difference between what the cedent pays and the recoverable it records is the cost of reinsurance. Under ASC 944-605-35-14, it is amortised over the life of the underlying reinsured contracts.
ASC 944-40-25-33 prohibits recognising a gain at inception, except where the reinsurance legally replaces the insurer and extinguishes the policyholder liability. Any net credit is deferred and amortised instead.
Market Risk Benefits Need a First Test
ASU 2018-12 requires both the ceding entity and the reinsurer to first determine whether a reinsurance contract covering guaranteed benefits falls under the market risk benefit provisions. Only if it does not do they move on to derivative and other guidance.
Ceded market risk benefits are typically measured at fair value. Their valuation reflects the reinsurer's own credit risk, which the direct benefit does not.
Worked Example: The OCI Mismatch on a Fully Reinsured Block
The illustration below is simplified and uses USD millions. It shows why a block that is 100% coinsured can still produce a net income effect under LDTI.
Assumptions:
- A closed block has a liability for future policy benefits of 500 at its locked-in rate of 5.0%
- At the current upper-medium grade rate of 3.5%, the same liability is 560
- On 1 January, the cedent coinsures 100% of the block with a reinsurer, for consideration of 560
- The recoverable's locked-in rate is set at 3.5%, the rate on the reinsurance date
- No benefits are paid in year 1 and rates stay flat at 3.5%, a deliberate simplification
| Item | Calculation | Result |
|---|---|---|
| Direct liability at locked-in rate, start | Given | 500 |
| Direct liability at current rate, start | Given | 560 |
| AOCI on direct liability, start | 500 − 560 | −60 |
| Recoverable, start | Equal to consideration at 3.5% | 560 |
| Cost of reinsurance at inception | 560 − 560 | 0 |
| Interest accretion on direct liability (expense) | 500 × 5.0% | −25.0 |
| Interest accretion on recoverable (income) | 560 × 3.5% | +19.6 |
| Net income effect, year 1 | −25.0 + 19.6 | −5.4 |
| Direct liability at locked-in rate, end | 500 + 25 | 525 |
| Direct liability at current rate, end | 560 × 1.035 | 579.6 |
| AOCI on direct liability, end | 525 − 579.6 | −54.6 |
| OCI movement, year 1 | −54.6 − (−60) | +5.4 |
| Total comprehensive income | −5.4 + 5.4 | 0 |
The block is fully reinsured, and total comprehensive income is zero. Net income still shows a cost of 5.4 in year 1, offset by an equal OCI gain as the AOCI balance unwinds.
Now change the price. If the reinsurer had charged 575 rather than 560, the extra 15 would be a cost of reinsurance, deferred and amortised over the life of the block.
If it had charged 545, the 15 would be a deferred gain. That gain is also amortised, because no gain can be recognised at inception.
The lesson for CFOs: "fully reinsured" does not mean "no earnings effect" under LDTI. Analysts and boards need to see the net income and OCI pieces together.
The lesson for reinsurance teams: the date a treaty takes effect sets the recoverable's locked-in rate. Treaty timing is now an accounting decision as well as a commercial one.
Which Treaty Types Create the Most LDTI Complexity?
Complexity depends on how closely the reinsurance cash flows mirror the direct cash flows. The table maps common treaty types to the usual issues.
| Treaty Type | Main LDTI Issue | Why |
|---|---|---|
| Prospective coinsurance on new business | Lowest complexity | Ceded cash flows mirror direct cash flows and rates |
| Coinsurance of an in-force block | Income and OCI mismatch | Recoverable locked in at the reinsurance date rate |
| YRT on level-premium term | Recoverable can become a liability in later years | Increasing ceded premiums against level direct premiums |
| Modco and funds withheld | Embedded derivatives and asset accounting | Assets stay with the cedent, so ASC 815 and ASC 860 issues arise |
| Reinsurance of guaranteed benefits on variable annuities | Market risk benefit assessment first | Fair value measurement and reinsurer credit risk |
For YRT books in particular, see our analysis of term life reinsurance pricing in a rising interest rate world. YRT rate changes feed directly into the recoverable's cash flows.
Which LDTI Reinsurance Mistakes Are Most Common?
Six mistakes recur in LDTI ceded reinsurance work. Most come from data and process gaps rather than misreading the standard.
Recoverable Not Updated With the Direct Unlock
Direct assumptions are updated at the annual review, but the recoverable runs on last year's basis. Net income then shows a gain or loss that does not exist economically.
Wrong Locked-In Rate for In-Force Treaties
The recoverable for an in-force treaty uses the direct contracts' original rates without a documented rationale. The chosen approach must be consistent, documented and agreed with auditors.
Cohort Mismatch Between Cedent and Reinsurer
The cedent and reinsurer use different cohort definitions or data lags. Disaggregated rollforwards and cohort-level calculations then do not reconcile.
Cost of Reinsurance Amortised on the Wrong Pattern
The amortisation pattern is not consistent with the underlying contracts or is changed without treating it as a change in accounting principle. That creates audit findings and restatement risk.
Ignoring Reinsurer Credit Risk on Ceded Market Risk Benefits
Ceded market risk benefits are valued without reflecting the reinsurer's own credit risk. The ceded value is then overstated, especially for weaker counterparties.
Disclosures Built Manually From Treaty Statements
Reinsurance recoverable lines in the rollforwards are assembled by hand each quarter. Small inconsistencies across treaties then compound into disclosure errors.
How Should Cedents Run LDTI for Ceded Business?
Running LDTI well needs a shared data model across actuarial, finance and outwards reinsurance. The data and questions below are a practical starting point.
What Data Is Needed per Treaty?
| Data Item | Why It Matters |
|---|---|
| Treaty effective date and coverage basis (prospective or in-force) | Sets the recoverable's locked-in rate approach |
| Policy-level cession records mapped to LDTI cohorts | Drives cohort-level recoverables and rollforwards |
| Ceded premium scales, including YRT rate tables | Feeds the ceded cash flows and net premium ratio |
| Ceding commission split between acquisition cost recovery and other | Decides DAC reduction versus cost of reinsurance |
| Reinsurer identity and credit standing | Needed for ceded market risk benefits and credit allowances |
| Settlement and experience refund terms | Affects expected ceded cash flows |
Which Questions Should the CFO Ask?
- Which treaties cover in-force blocks, and what locked-in rate does each recoverable use?
- Does every annual assumption review update the direct liability and recoverable together?
- How large is the net income versus OCI mismatch on reinsured blocks, and is it explained to the board?
- Are cohort definitions aligned with reinsurers and third-party administrators?
- How is ceding commission split between acquisition cost recovery and cost of reinsurance?

How Does LDTI Interact With Capital and Other Bases?
LDTI is a US GAAP measurement change. It does not change statutory reserves, NAIC risk-based capital or reserve credit for reinsurance.
That means the same treaty now shows three different pictures: GAAP net income and OCI, statutory reserves and capital, and economic value. Treaty decisions should be tested on all three.
Groups that also report under IFRS 17 face a fourth view. The two standards treat reinsurance held differently, so reconciliations between bases need a clear owner.
For asset-intensive and funded structures, collateral and asset look-through add another layer. Our piece on the funded reinsurance look-through problem covers that side.
What Are Life Reinsurance Teams Focusing on Now?
With large SEC filers several years into LDTI, attention has moved to explaining volatility rather than implementing the standard. Analysts now ask how much net income movement comes from discount rate mechanics on reinsured blocks.
Smaller and private insurers that adopted from 2025 are still stabilising processes. For them, cohort data from reinsurers and administrators is often the bottleneck.
Checklist for Heads of Reinsurance Accounting
Use this checklist before each LDTI reporting cycle.
- Every treaty is classified as prospective or in-force, with its locked-in rate approach documented
- Recoverables use the same cash flow assumptions as the direct liabilities at each update
- Policy-level cessions map to LDTI cohorts for every treaty
- Cost of reinsurance and deferred gains are amortised on a documented, consistent pattern
- Ceded market risk benefits reflect reinsurer credit risk
- Net income and OCI effects of reinsured blocks are explained to the board together
- Rollforward recoverable lines reconcile to treaty-level data
- Treaty terms and cessions come from a controlled system, not manual spreadsheets
For the last point, a centralised reinsurance treaty management platform keeps treaty terms, premium scales and settlement calculations in one place.

Frequently Asked Questions
What is LDTI?
LDTI is the FASB's Targeted Improvements to the Accounting for Long-Duration Contracts, issued as ASU 2018-12. LDTI requires annual review of cash flow assumptions, an upper-medium grade discount rate updated each reporting date, fair value for market risk benefits, simpler DAC amortisation and expanded disclosures.
When did LDTI become effective?
Under ASU 2020-11, LDTI became effective for SEC filers that are not smaller reporting companies for fiscal years beginning after 15 December 2022. For all other entities, LDTI is effective for fiscal years beginning after 15 December 2024, with interim periods one year later.
How does LDTI affect reinsurance recoverables?
LDTI affects reinsurance recoverables because ASC 944 requires recoverables to be measured consistently with the reinsured liabilities. When LDTI changed how the liability for future policy benefits is measured, ceded recoverables had to follow, using consistent cash flow assumptions and discount rate mechanics.
Does LDTI create an OCI mismatch on reinsured business?
LDTI can create an OCI mismatch on reinsured business when the direct liability and the recoverable use different locked-in discount rates. Interest accretion then differs in net income, with the offset in other comprehensive income, even on a fully reinsured block.
How is the cost of reinsurance treated under LDTI?
The cost of reinsurance under US GAAP is the difference between amounts paid to the reinsurer and the related recoverable. The cost of reinsurance is deferred and amortised over the life of the underlying reinsured contracts, and no gain is recognised at inception.
Are market risk benefits affected by reinsurance under LDTI?
Market risk benefits under LDTI are measured at fair value. ASU 2018-12 requires both the ceding entity and the reinsurer to first assess whether a reinsurance contract covering such benefits falls under the market risk benefit provisions before applying other guidance.
Do LDTI disclosures show reinsurance separately?
Yes. LDTI disclosure rollforwards for the liability for future policy benefits are presented gross of reinsurance, with a reconciling line for the related reinsurance recoverable. Insurers must also disclose the amount of any related reinsurance recoverable alongside each disaggregated rollforward.
Do reinsurers apply LDTI to assumed business?
Reinsurers reporting under US GAAP generally apply LDTI to assumed long-duration reinsurance contracts as they would to direct contracts. Assumed data may arrive with different cohorts and lags than the cedent's, so reinsurers need reliable cohort-level data from cedents and administrators.
