Passing any one threshold can make a segment reportable
For an entity applying AS 17, a properly identified business or geographical segment meets paragraph 27’s quantitative test if any one of its revenue, result or asset measures reaches the relevant 10% threshold. The denominators differ. After identifying reportable segments, paragraph 29 requires at least 75% of enterprise external revenue to be included, adding segments where necessary. Paragraph 31 also preserves a segment reportable in the immediately preceding period under the threshold tests, even when all three current measures fall below them.
This guide was checked on 22 October 2026 against ICAI’s AS 17 text and ICAI educational material on segment reporting. Establish applicability first: the standard’s introductory note provides exemptions for the stated SMC and Level II–IV non-company populations. These calculations assume an entity required to apply AS 17 or following it fully. Ind AS 108 requires its own framework; do not present this as a universal segment rule for every company.
Identify genuine segments before applying percentages
A cost centre is not automatically a business or geographical segment. Establish the component and its differing risks and returns from the operations and management information. Determine the primary and secondary reporting formats under the standard rather than letting the spreadsheet’s column order decide them. The quantitative worksheet starts after that identification decision; it cannot repair arbitrary grouping chosen to keep units below a threshold. The ICAI EAC opinion finalised on 3 June 2011 also explains identification before thresholds in its particular manufacturing facts; it is interpretative guidance, not a new amendment to the standard.
| Test | Numerator | Comparison base |
|---|---|---|
| Revenue, paragraph 27(a) | Segment external plus inter-segment revenue | 10% of all segments’ external plus inter-segment revenue |
| Result, paragraph 27(b) | Magnitude of segment profit or loss | 10% of the greater absolute combined profitable or loss-making segment result |
| Assets, paragraph 27(c) | Segment assets | 10% of the total assets of all segments |
| Coverage, paragraph 29 | External revenue of reportable segments | At least 75% of enterprise external revenue |
Keep the result pools separate
For the result test, total the results of profitable segments and separately total the losses of loss-making segments. Compare the absolute pools and use the larger one. Do not net the pools into enterprise profit or loss and then calculate 10% of that smaller number. Preserve the sign of every segment result in the source schedule, even though its magnitude is compared with the threshold.
Use correctly measured segment figures. Reconcile internal management measures to the standard’s segment revenue, expense and asset definitions; an EBITDA column or sales-only cost-centre report is not automatically the required segment result or asset base. Avoid arbitrary head-office allocations merely to make every corporate balance appear inside a segment. Maintain a documented allocation policy and a reconciliation for amounts that remain unallocated.
Use internal revenue for one test, external revenue for another
The paragraph 27 revenue comparison includes inter-segment revenue. The paragraph 29 coverage comparison uses enterprise external revenue. Build separate totals so consolidation eliminations do not accidentally shrink the first denominator, or internal transfers artificially inflate the second coverage percentage. The external revenue of a reportable segment is not necessarily its total revenue used in the 10% test.
The standard requires reconciliations between segment information and the enterprise financial statements. Keep the elimination entries and unallocated items visible instead of forcing the threshold worksheet to equal external revenue at every intermediate stage. Check that a segment’s inclusion is supported by its actual test result, management designation or continuity rule, rather than a convenient rounding of 9.5% to 10%.
Do not stop after the initial three tests
Where the initially reportable segments cover less than 75% of enterprise external revenue, identify additional segments until the requirement is met. A small segment can therefore become reportable despite failing all three 10% tests. Management may also designate an otherwise smaller segment under paragraph 28; keep the reason and resulting classification explicit. The 10% tests are not a general materiality safe harbour for unrelated disclosures.
Retain the previous period’s reportable list and the basis for inclusion. A segment that qualified under the immediately preceding period’s threshold tests does not simply disappear because this year’s numbers are smaller. Paragraph 32 separately addresses comparative data for a newly threshold-qualified current segment, with its impracticability qualification. Keep this comparative question separate from current-year coverage and complete the applicable primary/secondary disclosures after establishing the list.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: exactly 10% of combined segment revenue
Assume a properly identified segment earns ₹80 lakh externally and ₹20 lakh from other segments. All segments together earn ₹1,000 lakh including internal revenue. The segment numerator is ₹100 lakh and the ratio is exactly 10%, so the revenue test is met. Using only its ₹80 lakh external sales would miss the qualifying internal revenue.
Illustrative example 2: use the larger profit or loss pool, not the net
Assume segment profits are ₹80 lakh, ₹30 lakh and ₹10 lakh; segment losses are ₹175 lakh and ₹25 lakh. The profit pool is ₹120 lakh and absolute loss pool ₹200 lakh. The correct result threshold is ₹20 lakh. The ₹25 lakh loss segment qualifies on result; the ₹10 lakh profit segment does not qualify on result alone. Netting everything gives an ₹80 lakh loss and an incorrect ₹8 lakh threshold. Other revenue and asset tests must still be checked for every segment.
Illustrative example 3: asset test can independently establish reportability
Assume segment assets ₹160 lakh and total assets of all segments ₹1,600 lakh, measured consistently under AS 17. The asset ratio is exactly 10%. Even if the segment’s revenue and result ratios are below their thresholds, it meets the asset test. Do not substitute total company assets including unrelated unallocated items without reconciling the standard’s base.
Illustrative example 4: add small segments to achieve external coverage
Assume enterprise external revenue ₹1,000 lakh and the initially reportable segments cover ₹600 lakh, or 60%. At least ₹750 lakh must be covered, leaving a ₹150 lakh gap. Management adds two otherwise non-qualifying segments with external revenue ₹80 lakh and ₹90 lakh. Coverage becomes ₹770 lakh, or 77%, satisfying the test. The examples assume those segments’ other tests are also below threshold; the chosen additions need not equal exactly ₹150 lakh.
Illustrative example 5: do not use eliminated enterprise revenue as the 10% denominator
Assume all segments’ external revenue ₹900 lakh and inter-segment revenue ₹100 lakh, giving total segment revenue ₹1,000 lakh. A candidate segment has ₹80 lakh external plus ₹15 lakh inter-segment revenue, or ₹95 lakh. Its revenue ratio is 9.5%, below 10%. Dividing ₹95 lakh by the eliminated ₹900 lakh enterprise revenue would incorrectly produce approximately 10.56%. Test its result and assets separately before deciding its final status.
Illustrative example 6: prior-year reportability can survive a fall below thresholds
Assume a segment’s previous-year revenue was ₹120 lakh out of total segment revenue ₹1,000 lakh, or 12%, and it was reportable on that basis. Current revenue is ₹80 lakh out of ₹1,000 lakh, or 8%, with current result and asset measures also below 10%. Paragraph 31 still requires it to continue as reportable in the current period on these facts. The decline is not itself permission to remove the disclosure.

Sixteen practitioner FAQs
1. Must a segment pass all three 10% tests?
No. Passing any one of paragraph 27’s tests is sufficient for that quantitative stage.
2. Does exactly 10% qualify?
Yes. The standard uses 10% or more.
3. Does the revenue test include internal segment transactions?
Yes. Include the relevant inter-segment revenue in both the candidate amount and total segment-revenue base.
4. Can external enterprise revenue replace that denominator?
No. Preserve the different bases used by the revenue and coverage tests.
5. Can profit and loss segments be netted for the result threshold?
No. Compare the absolute profitable and loss-making pools and use the larger.
6. Can a loss-making segment be reportable?
Yes. Its result magnitude can meet the test, and revenue or assets may also qualify.
7. Does segment EBITDA automatically equal the required result?
No. Reconcile the actual measure to AS 17’s definitions and policies.
8. Is the asset denominator always total company assets?
Use the total assets of all segments and reconcile unallocated items appropriately.
9. What does the 75% test measure?
External revenue attributable to reportable segments relative to total enterprise external revenue.
10. Can internal transfers improve external-revenue coverage?
No. They are not external revenue.
11. Can a segment below all three 10% tests still be disclosed?
Yes. Management designation or the coverage and continuity requirements can make it reportable.
12. Is 10% a general materiality threshold for the entire accounts?
No. Paragraph 30 confines these thresholds to identifying reportable segments.
13. Can a prior qualifying segment automatically disappear below 10% this year?
No. Apply paragraph 31’s immediately preceding-period continuity rule.
14. Do newly qualifying segments raise a comparative-data question?
Yes. Paragraph 32 addresses restatement of presented comparative segment data unless impracticable.
15. Is every Tally cost centre a statutory segment?
No. Determine the segment from the standard’s business/geographical definitions and the actual facts.
16. Do these AS 17 tests determine Ind AS 108 compliance?
No. Confirm the applicable reporting framework before selecting the standard.
Working-paper organisation
Keep the source documents, calculation and final conclusion together for the same entity and period. If using assureFinancials or other assureOffice tools, use only confirmed available functions and retain this evidence with the output.
Conclusion
Keep three threshold calculations, an external-only coverage test and a prior-period continuity check in the same working. This prevents a correct-looking percentage from selecting the wrong segments or omitting a disclosure that the standard still requires.
