IFRS 17: The EU Exemption That Makes the Same Standard Give Different Answers

Two insurers can apply IFRS 17 to identical books of business, both lawfully, and report different numbers. The reason is not judgement or estimation. It is that the version of IFRS 17 endorsed for use in the European Union contains an exemption the version issued by the International Accounting Standards Board does not.

The requirement, as the IASB wrote it

IFRS 17 paragraph 22 is short and absolute: "An entity shall not include contracts issued more than one year apart in the same group. To achieve this the entity shall, if necessary, further divide the groups described in paragraphs 16–21."

This is the annual cohorts requirement. Its purpose is to stop an insurer masking an onerous recent cohort inside a profitable older one, which would defer losses the standard wants recognised immediately. The cost is operational: a book written over thirty years has to be divided into thirty groups, each tracked separately, each with its own contractual service margin to roll forward.

The exemption, as the EU endorsed it

The European Union endorsed IFRS 17 through Commission Regulation (EU) 2021/2036 of 19 November 2021. Its recital 12 states that "Union companies should have the option to exempt intergenerationally-mutualised and cash flow matched contracts", and that the option applies notwithstanding the definition of a group of insurance contracts in the standard's own appendix.

Article 2(2) makes it operative: "a company may choose not to apply the requirement laid down in paragraph 22". Article 2(2)(b) scopes it to "groups of insurance contracts that are managed across generations of contracts", subject to conditions drawn from Article 77b of the Solvency II directive.

So an EU-reporting insurer with intergenerationally-mutualised or cash-flow-matched business may lawfully omit annual cohorts for those contracts. An entity applying IFRS 17 as issued by the IASB may not.

Why this matters beyond the insurance sector

The wider lesson is one a finance audience rarely hears stated plainly: "IFRS" is not a single text. It is a set of standards issued by the IASB, which each jurisdiction then endorses, adopts, or declines to adopt through its own legal process. Endorsement is usually faithful. It is not always identical.

This particular divergence is also unusually quiet. The regulation contains no statement that the EU version departs from the IASB text. Recital 11 says only that deviations from IFRS "should be limited to exceptional circumstances" and should be narrow in scope. Recital 12 then introduces the exemption as an override of the standard's group definition. The departure is operative but never labelled as a departure, which is why a reader working only from the regulation can miss it.

The practical consequences are concrete. A group with EU and non-EU subsidiaries may need both treatments. A comparison between an EU insurer and a non-EU one on cohort-sensitive metrics is not like-for-like. And anyone reporting outside the EU should check what their own jurisdiction actually endorsed rather than assuming the EU position travels — it is a feature of the EU endorsement regulation specifically, and each jurisdiction's endorsement body publishes its own adopted text.

The exemption exists because the requirement proved genuinely hard

It would be easy to read the carve-out as lobbying. The documented record suggests the underlying difficulty was real, and the strongest evidence is that it persisted for years after implementation.

Annual cohorts were among the issues practitioners repeatedly put to the IASB's Transition Resource Group. They were still being raised to the Accounting Standards Advisory Forum in September 2024, more than eighteen months after the standard became effective, with the objection recorded in operational terms: "maintaining a growing number of cohorts containing fewer contracts becomes very costly". The IFRS Interpretations Committee twice declined to take application issues forward on the basis that the problems were not sufficiently narrow in scope to resolve through an interpretation.

Worth noting what does not exist. The IASB has not begun a post-implementation review of IFRS 17 — there is no request for information, no feedback statement and no staff analysis of application difficulties. So anything presented as the IASB's post-implementation findings on IFRS 17 is not drawn from a real document. The Transition Resource Group log, the three agenda decisions and the advisory forum papers are the primary record that exists.

What to do with this

If you prepare or audit insurance contract accounting in an EU entity, establish early whether the Article 2(2) option has been taken, because it changes the unit of account and therefore every downstream number. If you review group accounts, establish whether it has been taken consistently. And if you are reading a comparison of insurers' IFRS 17 results across jurisdictions, check whether cohorts are on the same basis before drawing a conclusion from it.

The endorsement regulation, including recitals 11 and 12 and Article 2(2), is published in full on EUR-Lex. Note that the text of IFRS 17 itself sits behind the IFRS Foundation's subscription, so paragraph 22 above is quoted from a national standard-setter's published compilation of the identical text.
