📋 '''Premium Allocation Approach (PAA)''' is a simplified measurement model permitted under [[Definition:IFRS17 | IFRS17]] for groups of [[Definition:Insurance contract | insurance contracts]] whose [[Definition:Coverage period | coverage period]] is one year or less, or where the approach produces results that do not materially differ from the full [[Definition:Building Block Approach (BBA) | Building Block Approach]]. Designed primarily with short-duration business in mind — the bread and butter of [[Definition:Property insurance | property]], [[Definition:Motor insurance | motor]], and many [[Definition:Commercial insurance | commercial]] lines — the PAA lets insurers measure the pre-claims liability by simply tracking unearned [[Definition:Premium | premiums]] in a manner conceptually similar to the traditional unearned premium reserve, rather than projecting all future [[Definition:Fulfilment cash flows | fulfilment cash flows]] from inception.

⚙️ Under the PAA, the liability for remaining coverage starts at the amount of premiums received (less any immediately expensed [[Definition:Acquisition cost | acquisition costs]], if the insurer elects that option) and is reduced over the coverage period to reflect the passage of time and the provision of services. There is no need to calculate a [[Definition:Contractual Service Margin (CSM) | Contractual Service Margin]] separately; profit emergence mirrors the earning of premium. However, the insurer must still test at each reporting date whether the group has become [[Definition:Onerous contract | onerous]] — and if it has, the full Building Block Approach mechanics kick in for the deficiency. For [[Definition:Claims | claims]] that have already been incurred, the liability for incurred claims is measured using discounted expected cash flows and a [[Definition:Risk adjustment | risk adjustment]], just as it would be under the general model.

💡 The PAA has been a practical relief valve for much of the non-life insurance sector. Without it, carriers writing millions of annual-term policies would face enormous modeling complexity for little incremental insight. Most general insurers have adopted the PAA for the vast majority of their portfolios, reserving the full BBA for longer-tail or multi-year contracts. Even so, implementation has not been trivial: the [[Definition:Onerous contract | onerous-contract]] testing requirement and the need to discount incurred-claims liabilities at current rates have introduced new processes and data demands that many finance and actuarial teams had not previously managed under legacy GAAP frameworks.
