Why it matters
Required for listed manufacturers (Tadawul, EGX, DFM/ADX); segments follow how the chief operating decision maker reviews performance, whether by product category, plant or geography. Poor segment reporting - over-aggregation, or external segments diverging from internal board packs - is a frequent regulator finding, can mask underperforming divisions from investors and lenders, and undermines the credibility of the wider financial statements once a mismatch with internal reporting is uncovered.
Diagnostic questions
Is the entity listed (or preparing to list) on an exchange such that IFRS 8 actually applies? Who is the chief operating decision maker in substance, based on what reports they actually review, not job titles? Do the reportable segments match the discrete financial information regularly reviewed by that decision maker, and does any aggregation of segments genuinely meet the similar-economic-characteristics criteria?
Recognition
- Confirm scope: IFRS 8 applies to entities with listed debt or equity, or those filing for listing - private manufacturers without public instruments are out of scope unless voluntarily adopting it.
- Identify the chief operating decision maker (CODM) - the function (which may be a person or a group, e.g. an executive committee) that allocates resources and assesses performance, based on actual governance practice, not the org chart title.
- Identify operating segments as the components of the entity for which discrete financial information is available and regularly reviewed by the CODM (e.g. by product category, plant, or geography, whichever the CODM's internal reporting pack actually follows).
- Apply the quantitative thresholds to determine reportable segments: a segment is reportable if its revenue (including intersegment), absolute profit or loss, or assets are 10% or more of the relevant combined/total amount; ensure reportable segments cover at least 75% of consolidated external revenue, adding segments if needed.
- Only aggregate two or more operating segments into one reportable segment if they have similar economic characteristics and are similar in the nature of products, production processes, customer type, distribution method, and regulatory environment - document the basis for aggregation.
- Cross-check the resulting external segment note against the actual board/CODM reporting pack before finalizing, since inconsistency between the two is a known audit and regulator focus area.
Measurement
Basis: segment amounts are reported using the measures actually provided to the CODM, which may differ from IFRS recognition and measurement principles used in the primary financial statements (e.g. management accounts basis, budget-rate FX, or allocations not required by IFRS). Included: segment revenue (external and intersegment), segment result, and, only if regularly reported to the CODM, segment assets and liabilities; allocation bases used for shared costs/assets across segments should be consistent and disclosed if material. Excluded/reconciled separately: unallocated corporate costs, income tax, and items not attributed to segments are shown as reconciling items rather than forced into a segment. Re-measurement/reassessment trigger: re-identify operating segments and reportable segments whenever the CODM's internal reporting structure changes (reorganization, new product line, disposal of a division, or change in the way the CODM reviews the business), and recompute the 10%/75% thresholds each reporting period since they are not a one-time test.
Presentation & disclosure
General information: factors used to identify reportable segments and the types of products/services from which each derives revenue; segment profit or loss and, if regularly reviewed by the CODM, segment assets and liabilities; a measure reconciliation from total reportable segment revenues, profit/loss, assets and liabilities to the corresponding consolidated IFRS totals, with material reconciling items described; geographic information - revenue from external customers and non-current assets split between the domicile country and all foreign countries (individually if material); revenue from any single external customer amounting to 10% or more of total entity revenue, and the identity of the segment(s) reporting it; basis of measurement used for segment items if it differs from IFRS measurement used in the primary financial statements.
Common mistakes
- Aggregating dissimilar divisions (different products, margins, or customer bases) purely to avoid disclosing a weak-performing segment separately
- presenting external segments that do not match the discrete packs actually reviewed by the CODM/board, which is readily detectable by regulators and auditors requesting board minutes
- omitting the 10%-customer concentration disclosure when a single customer'
- s revenue crosses the threshold
- failing to update segment identification when the CODM'
- s internal reporting structure changes (e.g. after a reorganization) and continuing to report legacy segments
- not reconciling segment totals to the consolidated financial statement totals, or reconciling without explaining material adjusting items.
Simple example
A listed Egyptian food group (amounts illustrative in SAR-equivalent for consistency) is reviewed monthly by its CODM using three discrete P&Ls: Dairy (external revenue SAR 180,000,000, segment profit SAR 22,000,000), Juice (external revenue SAR 90,000,000, segment profit SAR 9,000,000), and Snacks (external revenue SAR 40,000,000, segment loss SAR (3,000,000)); consolidated external revenue is SAR 310,000,000 and consolidated segment profit before unallocated items is SAR 28,000,000. Dairy (58% of revenue), Juice (29%) and Snacks (13%) each exceed the 10% revenue threshold, and combined they cover 100% of external revenue, so all three are reportable segments - management may not blend them into one 'food' segment even though all three are food products, because the CODM reviews them discretely and the products, customers and margins differ materially. No consolidation journal entry is required for segment identification itself (it is a disclosure-only exercise); the entity instead prepares a reconciliation: Total reportable segment profit SAR 28,000,000 less unallocated corporate costs SAR 5,000,000 = consolidated profit before tax SAR 23,000,000, disclosed in the segment note reconciliation.
Professional judgment
Identifying the CODM is a substance-over-form judgment: it can be a single executive, a management committee, or even the board, depending on who actually makes resource allocation and performance decisions - the answer should be evidenced by the reports that function actually receives, not by job titles. Aggregation of similar segments is another key judgment area, since the 'similar economic characteristics' test (similar long-term average gross margins, growth prospects, risk profiles) is qualitative and easy to apply too liberally to avoid disclosing an underperforming line; the aggregation rationale should be documented and revisited each period, not treated as a one-off decision. A further judgment concerns immaterial or borderline segments near the 10% thresholds - these need a formal calculation each period rather than a qualitative eyeballing, since small movements can flip a segment in or out of reportability. Governance practice: segment identification and aggregation conclusions should be minuted and reviewed by those charged with governance, given regulator focus on alignment between external segment notes and internal board reporting.
