Understanding the General Model under IFRS 17

The General Measurement Model (GMM) is the cornerstone of IFRS 17, the new international accounting standard for insurance contracts. Designed to bring greater transparency and consistency, the GMM serves as the standard method for measuring insurance liabilities, especially for long-term contracts. Unlike previous standards, IFRS 17 emphasizes a real-time view of profitability and expected cash flows, making financial reporting more reflective of actual economic value.

Under the GMM, insurers calculate the fulfillment cash flows—essentially the present value of future premiums, claims, and expenses—discounted using current market rates. This approach captures the time value of money and reflects changes in assumptions over time. A key component is the addition of a contractual service margin, which represents unearned profit. This margin is released gradually over the life of the contract as services are provided, aligning revenue recognition with service delivery.

This model is particularly relevant for long-duration contracts—like life insurance or annuities—where cash flows extend over many years. It allows stakeholders to better understand the timing and uncertainty of future obligations. By focusing on current estimates and regularly updating assumptions, the GMM promotes more dynamic and accurate reporting.

While the GMM is the default, IFRS 17 also introduces simplified approaches for specific contract types, such as the Premium Allocation Approach for shorter-duration policies. Still, the GMM remains central for complex, long-term liabilities. Its implementation demands robust data systems and actuarial expertise, marking a significant shift from legacy accounting practices.

In essence, the General Measurement Model isn’t just a new formula—it's a fundamental rethinking of how insurers report value, risk, and performance to investors and regulators alike.
