Under [[Definition:IFRS 17 | IFRS 17]], the international accounting standard for insurance contracts, the building block approach (also called the general measurement model) is the default method for valuing most long-duration and complex [[Definition:Insurance | insurance]] obligations. Its adoption represents one of the most significant changes in how insurers report their financial results globally.<br /> <br /> 📐 The model constructs the total value of an insurance contract from four discrete blocks: the present value of expected future [[Definition:Cash flow | cash flows]] (both inflows and outflows), a [[Definition:Risk adjustment | risk adjustment]] that quantifies the compensation the insurer requires for bearing uncertainty in those cash flows, a [[Definition:Discount rate | discount rate]] applied to reflect the time value of money, and the [[Definition:Contractual service margin (CSM) | contractual service margin (CSM)]], which represents the unearned profit the insurer expects to recognize over the coverage period. Each block is estimated and updated separately at every reporting date, meaning that changes in assumptions — such as revised [[Definition:Mortality | mortality]] rates or updated [[Definition:Claims | claims]] patterns — flow through specific blocks rather than being buried in an opaque reserve figure. This transparency is precisely what standard-setters intended.<br /> <br /> 📊 The practical significance for insurers and their stakeholders is substantial. By decomposing contract economics into visible building blocks, the approach gives [[Definition:Investor | investors]], [[Definition:Regulator | regulators]], and management a clearer view of where profit originates and how [[Definition:Risk | risk]] is evolving over time. Implementation, however, has been enormously demanding: carriers have had to overhaul [[Definition:Actuarial | actuarial]] models, [[Definition:Data warehouse | data infrastructure]], and [[Definition:Financial reporting | financial reporting]] systems to produce the granular estimates each block requires. [[Definition:Insurtech | Insurtech]] and [[Definition:Regtech | regtech]] vendors have responded with specialized tools for IFRS 17 compliance, and the building block approach has become a catalyst for broader data modernization across the industry.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:IFRS 17]]<br /> * [[Definition:Contractual service margin (CSM)]]<br /> * [[Definition:Risk adjustment]]<br /> * [[Definition:Premium allocation approach (PAA)]]<br /> * [[Definition:Actuarial reserving]]<br /> * [[Definition:Variable fee approach]]<br /> {{Div col end}}</div>
