Operating segment identification and disclosure

Segment disclosure is one of the few places IFRS mandates transparency using management's own internal view of the business rather than an external accounting construct, so getting it wrong (reporting segments the entity wishes to show rather than what the chief operating decision maker actually reviews) deprives investors and lenders of the disaggregated performance data they most need to assess a diversified contracting group with structurally different margin and risk profiles across building, infrastructure, MEP and equipment rental.

Does the chief operating decision maker regularly review discrete financial information organized by division, such as buildings, infrastructure/roads, MEP, or equipment rental, rather than a single consolidated view? Does any division meet the quantitative thresholds for revenue, profit or loss, or assets that would make it a reportable segment? Is segment information reported on the same measurement basis actually used in the internal management reports reviewed by the CODM, even where it differs from IFRS? Are segments being aggregated or presented differently from the CODM's actual internal view for external presentation convenience?

1. Identify the chief operating decision maker (CODM), the function (not necessarily a single individual) that allocates resources and assesses performance of the entity's operating segments.
2. Identify operating segments based on the internal management reports actually reviewed regularly by the CODM (by division, business line or geography), not the structure the entity would prefer to present externally.
3. Apply the quantitative thresholds (10% of combined revenue, profit/loss, or assets) to identify reportable segments, and aggregate similar segments only where they meet the aggregation criteria (similar economic characteristics and similar in nature of products/services, production processes, customer type, distribution method, and regulatory environment).
4. Ensure reportable segments cover at least 75% of total external revenue, adding segments as needed even below the quantitative thresholds.
5. Reconcile segment revenue, profit/loss, assets and liabilities to the entity's consolidated totals, explaining material reconciling items.

Report segment revenue, profit or loss, assets and liabilities using the measures actually reported to and used by the CODM for decision-making, even where these differ from IFRS recognition and measurement principles used in the primary financial statements (e.g. internal management adjustments, different allocation of shared costs); disclose the basis of measurement and reconcile to consolidated IFRS totals, explaining the nature and effect of any material differences.

Disclose: (1) factors used to identify reportable segments, including the basis of organization (by product/service, geography, or both); (2) types of products and services from which each reportable segment derives revenue; (3) segment revenue (external and inter-segment), profit or loss, assets, liabilities and other material items reviewed by the CODM; (4) reconciliations of segment totals to consolidated amounts; (5) entity-wide disclosures on products/services, geographic areas and major customers even if segment reporting is otherwise aggregated.

• Presenting segments based on external legal entity structure or a marketing-driven business line split rather than the actual internal reports reviewed by the CODM
• aggregating structurally dissimilar activities (e.g. low-margin, capital-light equipment rental with high-margin, capital-intensive infrastructure contracting) purely because they fall under the same regional management, without meeting the aggregation criteria
• omitting a segment that individually falls under the 10% quantitative thresholds but is regularly reviewed separately by the CODM and considered strategically significant
• failing to reconcile segment totals to consolidated financial statement totals, leaving unexplained differences.
