Internal:Training/IFRS17/The general model: subsequent measurement
🔗 Recall. In the previous page, you learned how the general model measures an insurance contract at initial recognition, setting up the four building blocks on day one. Now we turn to what happens next: how those building blocks evolve over time as the insurer delivers coverage, updates its assumptions, and settles claims.
🎯 Objective. In this page, you will learn:
- How the passage of time mechanically changes the liability through unwinding the discount, releasing the risk adjustment, and releasing the contractual service margin.
- How changes in estimates about the future are treated differently depending on whether they relate to future, current, or past service.
- How claims move through the stages of incurred, settled, and derecognised, and what each stage means for the financial statements.
Passage of time: unwinding discount, releasing RA, releasing CSM
⏳ Time never stands still. Once an insurance contract is on the books, the liability does not simply sit unchanged until a claim arrives. Even if nothing unexpected happens, the mere passage of time triggers three automatic adjustments. These adjustments reflect that the insurer is steadily fulfilling its promise to the policyholder, one day at a time. Understanding these three movements is the foundation of subsequent measurement under the general model.
📈 Unwinding the discount. When you first measured the liability, you discounted future cash flows back to their present value. As time passes and those cash flows draw closer, the present value increases, even if the expected amounts stay the same. This increase is called unwinding the discount, sometimes described as the "accretion of interest." Suppose AXA measured a group of property insurance contracts in Belgium at initial recognition with fulfilment cash flows of €8 million, discounted at 2%. One year later, even with no change in expectations, the liability grows by roughly €160,000 (€8 million × 2%) simply because those future payments are now one year closer. This accretion is recognised as insurance finance expense, not as a cost of delivering service.
🛡️ Releasing the risk adjustment. At initial recognition, the risk adjustment reflected the full uncertainty the insurer faced over the entire coverage period. As each period passes without the worst scenarios materialising, a slice of that uncertainty has been borne and is gone. The insurer releases a portion of the risk adjustment to reflect the reduction in remaining risk. That released amount flows into insurance revenue, because bearing risk is part of the service the insurer provides. Think of it like a security deposit on a rental flat in Lyon: each month you live there without damaging anything, a portion of the deposit is effectively "earned" by the landlord. When the lease ends, any deposit still held is returned or recognised.
🎁 Releasing the CSM. The contractual service margin is the unearned profit locked away on day one. As the insurer delivers coverage, it releases a portion of the CSM into insurance revenue. The pattern of release is determined by coverage units, which measure how much service is provided in each period relative to the total expected service remaining. If a five-year life insurance group provides equal coverage each year, roughly one-fifth of the CSM is released each year. The key principle is that profit appears in the income statement only as service is delivered, never all at once.
⚠️ Common misconception. Many learners assume that the unwinding of the discount is part of insurance revenue. It is not. Unwinding is a financing effect, not a service result. It appears separately in insurance finance income or expense, keeping the service picture clean.
🤔 Think about it. So far we have assumed that nothing changes except the calendar date. But what happens when the insurer's expectations about future cash flows turn out to be wrong, and estimates need updating?
Changes in estimates: future service adjusts CSM, current/past service hits P&L
🔄 Assumptions are living things. Insurance is built on estimates: how many claims will occur, how large they will be, when they will be paid. These estimates are updated every reporting period using the latest information. When the updated numbers differ from the previous ones, the insurer must decide where the impact lands. IFRS 17 draws a sharp line based on the period of service the change relates to. This distinction is one of the most important concepts in the entire standard.
📅 Future service adjusts the CSM. If a change in estimates relates to service the insurer has not yet delivered, the impact is absorbed by the CSM. For example, imagine AXA insures a group of motor insurance contracts in Germany and originally expected total claims of €5 million over the remaining coverage period. New data from the first winter suggests that claims will actually total €4.5 million, a favourable change of €500,000. Rather than recognising an immediate profit, the insurer increases the CSM by €500,000, which will then be released gradually as coverage continues. The logic is elegant: if the change affects future service, it should affect future profit, not today's.
📉 Unfavourable changes work the same way, up to a point. If the same group's expected claims had risen by €500,000 instead, the CSM would decrease by that amount. The CSM acts as a buffer, absorbing bad news about the future just as it absorbs good news. However, the CSM cannot go below zero. If the unfavourable change is so large that it would push the CSM into negative territory, the excess is recognised immediately as a loss in profit or loss. At that point, the group becomes onerous, and a loss component is established to track the shortfall.
⚠️ Common misconception. A frequent error is thinking that all changes in estimates adjust the CSM. They do not. Only changes relating to future service go through the CSM. Changes relating to current or past service, such as a re-estimate of a claim that has already been incurred, go directly to the income statement. The question to ask is always: "Has the service already been provided?" If yes, the CSM cannot absorb it, because the CSM represents profit on service still to come.
⚖️ Current and past service hit P&L directly. Suppose a severe hailstorm strikes a region in Spain during the current reporting period, and the insurer needs to increase its best estimate of claims for damage that has already occurred. This change relates to service already provided (the insurer was on risk when the storm happened), so the full amount goes straight to insurance service expenses in the income statement. Similarly, if a claim from a prior year is re-estimated upward because repair costs were higher than initially thought, that adjustment also bypasses the CSM and flows directly into the income statement as a cost of past service.
🤔 Think about it. We have now seen how estimates change and where the impact lands. But what actually happens when a claim event occurs and the insurer begins the process of paying out? How does the liability move through its final stages?
Claims incurred, settled, and derecognition
🌧️ From coverage to claim. The entire purpose of an insurance contract is to pay claims when covered events occur. When a claim is incurred, the nature of the liability changes. It is no longer about providing future coverage; it is about settling a specific obligation. Under IFRS 17, this shift matters because the liability now relates to past service, and any further adjustments affect the income statement directly rather than the CSM.
📝 Incurrence and estimation. A claim is incurred when the insured event happens, regardless of whether the policyholder has reported it yet. If a January storm damages 200 roofs in Brittany, those claims are incurred in January even if some homeowners do not file until March. At the point of incurrence, the insurer estimates the expected claim cost and reflects it in the fulfilment cash flows. This estimate includes the cost of claims handling and considers the timing of future payments, which continues to be discounted. The liability for incurred claims is measured using the same building-block approach, but the CSM is no longer involved because the service (being on risk during the storm) has already been delivered.
⚠️ Common misconception. Some learners believe that a claim is only recognised when the policyholder reports it. Under IFRS 17, the liability must reflect all claims that have been incurred, including those incurred but not yet reported (IBNR). The insurer uses actuarial methods to estimate these unreported claims every reporting period, ensuring the financial statements present a complete picture.
💶 Settlement and cash outflow. When the insurer pays a claim, cash leaves the business. The fulfilment cash flows decrease by the amount paid, and the liability falls accordingly. If a homeowner's roof repair in Brittany costs €12,000 and AXA pays the contractor directly, the liability drops by €12,000 and cash on the balance sheet decreases by the same amount. Settlement is straightforward in accounting terms: it is simply the discharge of an obligation that was already measured and waiting to be paid. If the actual payment differs from the previous estimate, the difference is an adjustment to insurance service expenses in the current period, because it relates to past service.
🚪 Derecognition: closing the book. Derecognition means removing the insurance contract from the balance sheet entirely. This happens when the obligation is extinguished, typically because all claims have been settled and the coverage period has ended. It can also occur if the contract is cancelled or transferred. Once derecognised, the contract no longer contributes to the liability, the CSM, or the risk adjustment. Any remaining balances at the point of derecognition are released to the income statement. The lifecycle is complete: the contract was recognised, measured, fulfilled, and finally removed.
Takeaways
📌 Key takeaways.
- The passage of time triggers three automatic movements: the discount unwinds (a financing effect), the risk adjustment releases (reflecting reduced uncertainty), and the CSM releases (recognising earned profit).
- Changes in estimates about future service adjust the CSM, preserving the link between profit and service delivery, while changes relating to current or past service go directly to the income statement.
- Claims progress from incurrence (including IBNR) through settlement to derecognition, and once incurred, any re-estimates bypass the CSM and hit profit or loss immediately.
