Internal:Training/IFRS17/Why insurance broke global standards
🔗 Recall. In the previous page, you learned how an insurer's balance sheet is dominated by reserves and how its income statement raises hard questions about when revenue is earned and how to value an uncertain promise. Now we build on that by exploring why those hard questions led different countries to radically different answers, and why the world eventually needed a single standard to replace them all.
🎯 Objective. In this page, you will learn:
- Why insurance accounting developed differently across countries, and why that fragmentation was a problem for investors, regulators, and insurers themselves.
- What IFRS set out to achieve, and why insurance was the one industry that resisted a single global accounting language for decades.
- Why IFRS 4 was only ever a stopgap, and what specific failures it created that made IFRS 17 necessary.
Different countries, different answers
🌍 A patchwork of rules. Insurance is one of the oldest industries in the world, and for most of its history, each country developed its own way of accounting for insurance contracts. This happened because insurance accounting must answer questions that sit at the intersection of actuarial science, finance, and law, and different national traditions emphasised different priorities. In France, the Plan Comptable framework leaned heavily on prudence, requiring insurers to hold cautious, often inflated reserves that smoothed results and protected policyholders. In the UK, the emphasis fell on giving a true and fair view to shareholders, which meant reserves were expected to be realistic best estimates rather than deliberately conservative buffers.
🔀 Concrete divergence. To see what this meant in practice, imagine two identical motor insurance portfolios, one booked by an insurer in Germany and one by an insurer in Spain. Both cover the same types of drivers, face the same expected claims, and collect the same premiums. Yet the German insurer, following the German Commercial Code (HGB), might report a liability of €85 million for future claims, while the Spanish insurer, following its local regulatory framework, might report €72 million for the very same risk. Neither number is "wrong" within its own system, but an investor comparing the two would have no way of knowing whether the gap reflects genuine economic differences or simply different accounting choices.
⚠️ Common misconception. It is tempting to assume that conservative accounting is always safer or "better." In reality, overly prudent reserves can be just as misleading as optimistic ones. If an insurer in France holds reserves far above the realistic estimate, its balance sheet understates its true financial strength, and its income statement suppresses profit in early years only to release hidden gains later. This obscures the real economic picture rather than clarifying it.
📉 Why fragmentation hurt. The consequences of this patchwork were practical and serious. Capital markets are global: an investor in New York evaluating an insurer like AXA, which operates across dozens of countries, had to wrestle with multiple local accounting regimes consolidated into a single set of financial statements. Comparing AXA's results with those of a UK or Swiss competitor was an exercise in guesswork, because the accounting rules themselves produced different numbers for economically identical transactions. Regulators, too, struggled to assess cross-border groups when the building blocks of each subsidiary's accounts were shaped by local convention rather than a shared logic.
🤔 Think about it. If the problem was that every country had its own rules, what would it take to create a single, globally accepted accounting language, and why did insurance prove to be the hardest industry to bring into that project?
IFRS and the promise of one global language
📜 The birth of a global project. The idea of a single set of accounting standards for the entire world took shape in the 1970s with the creation of the International Accounting Standards Committee (IASC), later reorganised as the International Accounting Standards Board (IASB). The goal was ambitious: if companies in every country reported their finances using the same rules, investors could compare a Belgian bank with a Japanese manufacturer on a level playing field. By the early 2000s, this vision was becoming reality. The European Union mandated that all listed companies adopt International Financial Reporting Standards from 2005 onwards, and over 140 countries eventually required or permitted their use.
🏗️ Standard by standard. The IASB tackled industries one at a time, issuing standards for revenue recognition, financial instruments, leases, and more. Each new standard replaced the local rules that had previously governed that topic, bringing consistency across borders. A revenue transaction in Italy would be accounted for the same way as one in Germany or Japan. The programme worked well for most industries, but insurance proved to be a stubborn exception. The fundamental problem was the one you explored in the previous page: insurance revenue and liabilities are deeply tied to uncertain future events, and reasonable experts could not agree on how to measure promises that might not be settled for decades.
⚠️ Common misconception. People sometimes believe that IFRS was designed primarily for European companies. While the EU's 2005 adoption mandate was a landmark moment, IFRS is a truly global project. Countries across Asia, Africa, and Latin America also use or converge with IFRS. The standards are not European rules applied elsewhere; they are international rules that Europe was among the first to adopt at scale.
🧩 Insurance as the missing piece. By the mid-2000s, IFRS had transformed accounting for nearly every type of business. Banks reported financial instruments under IAS 39 (later IFRS 9). Manufacturers recognised revenue under IAS 18 (later IFRS 15). But insurers were still using their old national rules for the core of their business: insurance contracts. The IASB had tried to develop an insurance standard since the late 1990s, but the technical challenges were enormous. How do you measure a liability that depends on events twenty or thirty years in the future? How do you recognise revenue when the service is a standing promise of protection rather than a delivered product? These questions had no easy answers, and the debate stretched on for years.
🤔 Think about it. If the IASB could not finish a proper insurance standard in time for the 2005 IFRS adoption deadline, what did insurers actually use in the meantime, and how well did that temporary solution hold up?
IFRS 4 as a temporary compromise and why IFRS 17 was needed
🕐 A placeholder, not a solution. Facing the 2005 deadline, the IASB issued IFRS 4 as an interim standard for insurance contracts. Rather than prescribing a new measurement model, IFRS 4 essentially told insurers: keep using whatever local accounting rules you already have, but disclose more information so that readers of your financial statements can at least see what you are doing. For an insurer like AXA, this meant that the French subsidiaries continued to follow French rules, the German subsidiaries followed German rules, and the UK subsidiaries followed UK rules, all within the same group consolidated accounts. IFRS 4 did impose a few guardrails, such as prohibiting insurers from removing prudence margins that already existed in their reserves, but it did not fix the core problem of incomparability.
📊 The failures of IFRS 4. Over the decade that IFRS 4 remained in force, its weaknesses became increasingly apparent. First, the standard perpetuated the very fragmentation it was supposed to bridge: two insurers in the same country, one using local GAAP and one using a slightly different permitted practice, could still report different numbers for identical risks. Second, because the standard allowed a wide range of measurement approaches, analysts found it nearly impossible to compare profitability across insurers. Third, IFRS 4 said almost nothing about how to present insurance revenue in the income statement, so some insurers reported gross premiums written, others reported premiums earned, and the resulting figures were not comparable. In practice, reading the insurance section of a set of IFRS financial statements often told you more about the insurer's home country than about its economic performance.
⚠️ Common misconception. Some people believe that IFRS 4 was simply "bad" and should have been replaced immediately. In fact, IFRS 4 served an important political and practical purpose: it allowed the insurance industry to join the IFRS world in 2005 without waiting another decade for a full standard. The problem was not that IFRS 4 existed, but that it stayed in force for far longer than anyone intended, lasting from 2004 until 2023.
🔧 Why IFRS 17 became necessary. The IASB spent over fifteen years developing a replacement. The project went through multiple exposure drafts, hundreds of comment letters from insurers, actuaries, and regulators, and several major redesigns. The result, published in May 2017 and effective from January 2023, was IFRS 17. Its ambition was to solve every problem that IFRS 4 had left open. It would impose a single measurement model so that the same risk produces the same liability regardless of the insurer's home country. It would define insurance revenue not as premiums received but as the value of service delivered, aligning insurance with the logic used in other industries. And it would require insurers to break their liabilities into transparent, separately disclosed components, giving investors the tools to understand what drives changes in an insurer's financial position from one period to the next. The pages that follow in this training will take you through each of those components in detail.
Takeaways
📌 Key takeaways.
- Insurance accounting developed differently in every country, and this fragmentation made it nearly impossible for investors, analysts, and regulators to compare insurers across borders.
- The IASB's IFRS project brought a single accounting language to most industries, but insurance was the last major holdout because the measurement of long-term, uncertain promises proved technically and politically difficult to standardise.
- IFRS 4 was a necessary but temporary compromise that perpetuated local differences; IFRS 17 replaced it with a single measurement model, a new definition of revenue, and transparent liability components designed to make insurance accounting globally consistent and comparable.
