Onerous contracts and the loss component (IFRS 17)

In 2026 an insurer takes on a portfolio of contracts with 1,000 of expected premiums and 1,040 of outflows and risk adjustment. A local standard would have seen it only at the closing, through a premium deficiency test. IFRS 17 writes it down at once: a loss of 40 in profit, the day the contract is recognized. A contract is onerous, per paragraphs 47 to 52 of the standard, when the fulfilment cash flows, added to acquisition cash flows already paid and to the group's cash flows to date, produce a net outflow. Contracts are therefore sorted from inception into three profitability buckets, onerous, with no significant possibility of becoming onerous, and others, which prevents a profitable contract from offsetting a loss-making one. The onerous group carries no contractual service margin, but a loss component, tracked separately: later changes in estimates relating to future service raise or lower it, and a share of the expected claims and premium allocated is booked against it rather than through profit. It runs off as service is provided, or reverses if estimates improve. For contracts under the simplified approach, the presumption is the other way round: a group is not onerous unless facts show otherwise, and a general-basis measurement is then needed. Analysts watch the loss component as an early signal of poor underwriting.
