The Hidden Trap in IFRS 19 Relief

Many groups currently believe IFRS 19 removes the subsidiary-level burden of IFRS 18 MPM disclosure.
In practice, some may discover the opposite — that their current consolidation architecture cannot support the disclosures required in Q1 2027.

IFRS 19 is a genuine and meaningful relief mechanism. For eligible subsidiaries, it removes disclosure requirements that carry significant preparation cost but limited value for non-capital-market users.

But there is one area where IFRS 19 offers no meaningful relief — and it happens to be the most operationally demanding requirement introduced by IFRS 18: the disclosure of Management-defined Performance Measures.

For groups that have assumed IFRS 19 provides a clean exit from the subsidiary-level implications of MPM disclosure, the reality is considerably more complicated.

This article focuses on the one area where IFRS 19 provides no meaningful relief.

MPM Reconciliation Is Not Reduced

IFRS 19 does reduce certain IFRS 18-related disclosures — narrative explanations of MPMs, qualitative descriptions of performance reporting, IFRS 18 breakdown narratives. These reductions are real.

What IFRS 19 does not reduce is the MPM reconciliation requirement itself: the obligation to reconcile each MPM to the nearest IFRS-defined subtotal, including the income tax effect and the effect on non-controlling interests for each individual reconciling item.

This is not an oversight. It reflects a deliberate design choice by the IASB: if a subsidiary uses MPMs in public communications, the discipline introduced by IFRS 18 applies in full.

Why This Is a Group-Wide Data Problem

The practical implications become clear when the reconciliation is examined in detail.

Consider a single reconciling item: the exclusion of a goodwill impairment of 100. To calculate the required disclosures, the group needs to know:

• in which subsidiary or subsidiaries that impairment arose

• the applicable tax rate in each relevant jurisdiction

• the NCI ownership percentage in each relevant subsidiary

• whether any portion of the impairment is tax-deductible

Now multiply that across five, eight, or twelve reconciling items — restructuring costs, acquisition-related expenses, share-based payment exclusions, gains on disposals — each arising in different jurisdictions, different subsidiaries, different NCI structures.

The key point: a parent company cannot produce an auditable MPM reconciliation by working from group-level numbers alone. The data lineage runs from the subsidiary upward. If subsidiaries are not reporting the right information, the reconciliation cannot be constructed after the fact.

This is not a consolidation exercise. It is a group-wide data collection problem that requires a consolidation package redesigned to capture adjustment-level attribution — not just entity-level financial data.

The Group Structure Problem: Where It Gets Harder

For groups with complex legal structures, the difficulty compounds.

Listed subsidiaries

Many large multinational groups operate with partially owned listed subsidiaries. These subsidiaries face the full IFRS 18 disclosure framework in their own financial statements—while simultaneously serving as a source of subsidiary-level tax and NCI data for the parent's consolidated MPM reconciliation.

The burden is effectively doubled: full IFRS 18 compliance in their own right, plus supporting the group reconciliation with item-level data.

Regional holding companies

Intermediate parents are eligible for IFRS 19 only if they have no public accountability and their own parent produces publicly available Full IFRS consolidated financial statements. Where a regional holding company has listed debt or other characteristics that create public accountability, it falls outside IFRS 19's scope — bearing the full IFRS 18 MPM burden directly, while also contributing subsidiary-level data upward.

For large multinational groups, each layer that falls outside IFRS 19 eligibility represents a node where the full MPM disclosure architecture must be operational — not just for its own statements, but as a data source for the consolidated group.

The Organisational Risk: IR and Consolidation Are Not Talking

Under IAS 1, IR activity operated outside the financial reporting boundary. Earnings releases, investor presentations, and capital markets communications were not part of the audited financial statements. The consolidation function was not involved in those decisions, and did not need to be.

Under IFRS 18, that boundary no longer exists.

Every subtotal of income and expenses that IR uses in a public communication is a potential MPM. If IR continues to define and use those measures without involving the consolidation function, the obligation to reconcile them — with item-level tax effects and NCI impacts across the group — lands on the consolidation team regardless.

IR teams are accustomed to moving quickly and defining performance narratives independently. That is appropriate for communications. It is not appropriate for measures that are now, under IFRS 18, part of the audited financial statements.

If you have not yet had a conversation with your IR function about which APMs they plan to use in 2027 communications — and what those measures will require from the consolidation package — that conversation is overdue.

The Timeline Is Already Running

IFRS 18 is effective for annual reporting periods beginning on or after 1 January 2027. But the standard also applies to interim financial statements in the initial year of adoption.

For a December year-end entity, the first MPM disclosure obligation falls not at year-end 2027 — but at Q1 2027, typically filed within weeks of the period close.

"We will sort out our APMs by year-end" is not a sufficient plan.

There is an additional point that is easy to overlook. An MPM is defined in relation to the reporting period of the financial statements in which it appears. A group cannot simply review its annual report APMs and assume it has identified all its MPMs. Every earnings release, every investor day presentation, every half-year report must be assessed separately. For groups with active IR programmes — quarterly earnings calls, H1 presentations, capital markets days — the population of potential MPMs is larger than it first appears.

ESMA made its position explicit in its February 2026 public statement: information on the anticipated effects of IFRS 18 should be disclosed as soon as it becomes available, with groups completing their assessment in the first half of 2026 expected to disclose in their June 2026 interim statements. For those not yet complete, disclosure in H2 2026 interim reports is the implicit expectation.

Working backward from Q1 2027:

The Q1 interim report requires MPM disclosures if any relevant measures appear in Q1 public communications → those disclosures require item-level tax and NCI data from subsidiaries → that data requires a redesigned consolidation package → that redesign requires a decision — made now — on which APMs to retain, discontinue, or restructure.

That decision is not a financial reporting decision. It is a communications strategy decision that happens to have financial reporting consequences. It requires CFO and IR leadership, not just the technical accounting team.

The IASB's Signal: Use MPMs Deliberately, or Not at All

The IASB did not prohibit MPMs. But by requiring item-level tax and NCI calculations, subjecting MPMs to audit, and declining to provide IFRS 19 relief for the reconciliation requirement, the standard effectively signals: use MPMs deliberately, or do not use them at all.

For many groups, the honest assessment will be that the data infrastructure required — across multiple jurisdictions, multiple NCI structures, multiple layers of consolidation — exceeds what can reasonably be built before 2027.

The strategic response may not be to build that infrastructure. It may be to reconsider which measures genuinely need to be disclosed as MPMs, and to redesign external communications accordingly.

Conclusion: Two Options, No Third

For groups still using APMs in public communications, the choice is binary:

1. Redesign the consolidation package to support auditable MPM reconciliations, or

2. Redesign IR communications to eliminate measures that trigger the MPM framework

There is no third option that preserves both the current IR approach and the current consolidation architecture.

IFRS 19 is a genuine relief mechanism — for most of what it covers. But it was not designed to absorb the group-wide data implications of IFRS 18 MPM disclosure. The trap is not visible in the text of IFRS 19 alone. It becomes visible only when the two standards are read together, the group's legal structure is mapped against eligibility, and someone asks IR which APMs they plan to use next year.

That conversation needs to happen now.
