EXECUTIVE BRIEFING
Why professionals should treat IFRS 18 as a reporting operating-model project—not a presentation-only change.
DEADLINE
Mandatory for annual reporting periods beginning on or after 1 January 2027; early application is permitted.
WHAT CHANGES
Income-statement structure, defined subtotals, management-defined performance measures, and aggregation/disaggregation.
WHAT TO DO NOW
Map the P&L, identify MPMs, design comparative data, update controls, systems and reporting packs.
Professional implication
Do not wait for the first 2027 close: comparative information and internal management reporting need preparation.
Treat IFRS 18 as a cross-functional programme spanning accounting policy, FP&A, data, consolidation, controls, investor communications and audit.
Prioritise the areas where management judgement, data granularity and system mapping intersect.
BOARD QUESTION
Can we explain—before year-end—how our current P&L and management measures will translate into IFRS 18?
SUCCESS TEST
A controlled bridge from current reporting to IFRS 18 reporting, with reconciled comparatives and auditable MPM disclosures.

OPERATING
Residual category; includes income/expenses from main activities not classified elsewhere.
INVESTING
Income/expenses from investments and assets, subject to the specified main-business-activity rules.
FINANCING
Income/expenses from financing and liabilities, subject to specified main-business-activity rules.
OPERATING PROFIT
Defined subtotal that improves comparability of operating performance.
PROFIT BEFORE FINANCING & TAX
A second defined subtotal between operating/investing results and financing/tax.
MPMs + DISCLOSURES
Management-defined performance measures become subject to specific disclosure requirements.

TRANSITION TIMELINE
A practical 5-month implementation plan from September 2026 to the 2027 reporting cycle.
SEP 2026
- Baseline
P&L mapping + gap assessment
OCT 2026
- Design
Policy decisions + MPM inventory
NOV 2026
- Build
Data, consolidation & disclosure changes
DEC 2026
- Dry run
Comparatives + control testing
JAN 2027
- Go-live
IFRS 18 reporting period begins
CRITICAL PATH
P&L mapping → MPM inventory → comparative-data design → systems build → dry run → governance sign-off.
ESCALATION TRIGGER
If comparative information cannot be recreated cleanly, escalate immediately to controllership, data owners and the auditor.

IMPACT MAP: WHERE THE WORK WILL LAND
Illustrative prioritisation for a typical corporate finance function. Replace scores with your own assessment.
[Bar Chart: Impact Map]
- Investor reporting
- Controls
- ERP / data
- Consolidation
- Comparatives
- MPMs
- P&L mapping
- Accounting policy
HIGH PRIORITY
Policy mapping, MPMs and controls should be owned by senior finance leadership.
DATA DEPENDENCY
Comparatives and consolidation may require account-level mapping and historical reconstruction.
COMMUNICATION
Investor and management reporting should reconcile to the new presentation architecture.
Page 6
[Process Flow Diagram]
CURRENT P&L (GL accounts + existing subtotals) → CLASSIFICATION (Operating / investing / financing) → DEFINED SUBTOTALS (Operating profit + profit before financing & tax) → DISCLOSURE LAYER (MPMs + specified expenses + aggregation/disaggregation)
Professional control point
- Maintain a traceable account-to-category mapping table with owner, rationale and evidence.
- Flag accounts requiring entity-specific judgement, especially for entities whose main business activities include investing or financing.
- Reconcile the mapped P&L to the ledger and consolidation output before designing disclosures.

MANAGEMENT-DEFINED PERFORMANCE MEASURES: GOVERNANCE FIRST
MPMs are not simply KPI labels; they require a controlled process for identification, reconciliation and disclosure.
Does management use the subtotal outside the financial statements?
YES / NO
Is it used to communicate management’s view of an aspect of financial performance?
YES / NO
MPM REGISTER
Measure name
Definition & formula
Why management uses it
Public communications where used
IFRS subtotal to reconcile to
Tax effect / disclosure inputs
Owner + approval date
Evidence & control sign-off
LIKELY MPM WORKSTREAM
Document definition, calculation, reconciliation, explanation, governance owner and consistency across communications.
NOT AN MPM
Still assess whether another IFRS requirement applies and whether the measure creates communication inconsistency.

[Bar Chart: Illustrative data-readiness pressure (1-5)]
- Audit evidence
- Disclosure data
- Consolidation
- Historical data
- GL mapping
DATA LINEAGE
GL → subledger → consolidation → reporting cube → financial statements → disclosure.
RECONCILIATION
Every material reclassification should be explainable and reproducible.
CONTROL EVIDENCE
Retain mapping files, approvals, transformation logic, reconciliations and sign-offs.

TARGET OPERATING MODEL
Assign ownership before the first reporting cycle.
CFO / Audit Committee — Sponsor, risk appetite, major judgement escalation
Controller — Accounting policy, mapping, technical conclusions
FP&A — Management measures, forecast/plan reconciliation
Data / IT — Data lineage, reporting logic, ERP/consolidation changes
Investor Relations — Consistency across public communications
Internal Audit / Assurance — Independent control and process challenge
GOVERNANCE CADENCE
Weekly implementation PMO → monthly steering committee → pre-close audit readiness review.

INDUSTRIAL/CONSUMER
Priority:
- P&L mapping
- MPM inventory
- Expense disaggregation
- Comparative data
- ERP / consolidation mapping
Risk: inconsistent management and statutory reporting.
BANK/INSURER
Priority:
- Main-business-activity assessment
- Operating classification implications
- Product / portfolio data
- MPM governance
- Investor communication
Risk: category conclusions driven by insufficient evidence.
DIVERSIFIED GROUP
Priority:
- Entity-by-entity mapping
- Central policy governance
- Intercompany / consolidation logic
- Consistent MPM framework
- Comparative reconstruction
Risk: local variations break group comparability.

TOP IMPLEMENTATION RISKS & RESPONSES
Focus leadership attention on failure modes that can delay or weaken adoption.
Incomplete account mapping
Material items remain outside the designed classification logic.
Owner: Controller
Mitigation: GL-to-P&L reconciliation
Uncontrolled MPMs
Different measures appear across results, presentations and disclosures.
Owner: CFO / IR
Mitigation: central MPM register
Weak comparative data
2026 information cannot be reconstructed consistently.
Owner: Data / FP&A
Mitigation: historical bridge + dry run
Late system changes
Reporting logic changes are introduced without testing.
Owner: CIO / Finance IT
Mitigation: controlled release + UAT
