Aggregation Criteria for Operating Segments under Ind AS 108

Updated 11 October 2026 · Fact-checked

Aggregation lets you combine two or more operating segments into one reportable segment. It is allowed only if it fits the core principle of Ind AS 108, the segments have similar economic characteristics, and they are similar in the products, production processes, customers, distribution methods and, if applicable, regulatory environment. All conditions must be met.

Understand Aggregation Criteria for Operating Segments

Ind AS 108 asks you to report segments the way management sees the business. Sometimes management reviews many small operating segments. Reporting each one separately can bury users in detail without adding insight. Aggregation solves this by combining segments that behave alike.

Paragraph 12 says that segments with similar economic characteristics often show similar long-term financial performance. For example, you would expect similar long-term average gross margins. Aggregation is a permission, not a duty. It is allowed only if it is consistent with the core principle of the standard.

There are three layers of test. First, aggregation must be consistent with the core principle. Second, the segments must have similar economic characteristics. Third, they must be similar in each of five respects: (a) nature of products and services, (b) nature of production processes, (c) type or class of customer, (d) methods of distribution, and (e) if applicable, nature of the regulatory environment, such as banking, insurance or public utilities.

The word each matters. Failing even one applicable criterion blocks aggregation. Criterion (e) applies only where regulation is relevant, so a non-regulated business can ignore it.

Do not mix this up with the quantitative thresholds. Aggregation is applied to operating segments first. The aggregated segment is then tested against the 10 per cent thresholds in paragraph 13. Paragraph 14 is a separate, more relaxed rule for small segments that fall below the thresholds. It needs similar economic characteristics and a majority of the paragraph 12 criteria, not all of them.

If you aggregate, paragraph 22 requires disclosure. You must describe the judgements management made, including a brief description of the segments aggregated and the economic indicators assessed to conclude they share similar economic characteristics.

Key rules to remember

Aggregation test (para 12)
Aggregate if: core principle met + similar economic characteristics + similar in (a) products/services, (b) production processes, (c) customers, (d) distribution, (e) regulatory environment if applicable
All conditions must hold. Aggregation is optional, not compulsory.
Quantitative thresholds (para 13)
Report separately if: revenue ≥ 10% of combined revenue of all segments, OR |profit or loss| ≥ 10% of the greater of combined profit of profit-making segments and combined loss of loss-making segments, OR assets ≥ 10% of combined assets
Revenue includes intersegment sales. Meeting any one test is enough. Applied to segments after any aggregation.
Combining small segments (para 14)
Combine below-threshold segments only if: similar economic characteristics + majority of para 12 criteria shared
A lighter test than para 12. Only for segments that do not meet any threshold.
Disclosure of aggregation (para 22(aa))
Disclose: judgements made, brief description of aggregated segments, economic indicators assessed
Also give the basis of organisation and types of products and services under para 22(a) and (b).

How to solve Aggregation Criteria for Operating Segments questions

Use this order for any question on aggregation. It keeps your answer structured and shows the examiner you know the rule.

  1. 1Identify the operating segments first, using paragraphs 5 to 10. Aggregation applies only to operating segments, not to corporate headquarters or post-employment plans.
  2. 2Check whether the segments have similar economic characteristics. Compare long-term average gross margins or similar indicators from the data.
  3. 3Test each of criteria (a) to (d) one by one. Write a line for each: similar or not similar.
  4. 4Test criterion (e) only if a regulatory environment is relevant to the segments.
  5. 5Decide. If every applicable criterion is met and the core principle is respected, aggregation is permitted. If any one fails, keep the segments separate.
  6. 6Apply the 10 per cent thresholds of paragraph 13 to the resulting segments to decide which are reportable.
  7. 7State the disclosure needed under paragraph 22: judgements, segments aggregated and economic indicators assessed.

When to use it: Use in MCQs and short case-based questions where you must quickly decide if two segments can be combined.

  1. Scan the data for margins. If long-term margins differ widely, economic characteristics are not similar. Stop and answer no.
  2. Tick off products, process, customers and distribution. One mismatch means no aggregation.
  3. Check if the question mentions a regulator such as RBI or IRDAI. If it does, add the regulatory test.
  4. If all pass, say aggregation is permitted, not required.
  5. Remember a small segment below thresholds uses paragraph 14, which needs only a majority of the criteria.

Common mistakes in Aggregation Criteria for Operating Segments

  • Saying segments must be aggregated if they are similar.

    Students read the rule as a command.

    Fix: Paragraph 12 says segments may be aggregated. It is a choice, and only when all conditions are met.

  • Aggregating when only some of the five criteria match.

    Students confuse paragraph 12 with the majority test in paragraph 14.

    Fix: Under paragraph 12, similarity is needed in each criterion. The majority test applies only to below-threshold segments in paragraph 14.

  • Applying the 10 per cent thresholds before aggregation.

    Students jump to the numbers because they are easy to compute.

    Fix: Identify operating segments, aggregate if allowed, then apply the thresholds to the result, as paragraph 11 sets out.

  • Always testing the regulatory environment criterion.

    Students treat the list as five fixed tests.

    Fix: Criterion (e) applies only if applicable. For an unregulated manufacturer, ignore it.

  • Ignoring economic characteristics and checking only the five criteria.

    The list looks like the whole test.

    Fix: Similar economic characteristics is a separate requirement. Different long-term margins can block aggregation even when the five criteria look alike.

  • Forgetting the disclosure after aggregating.

    Students stop once the decision is made.

    Fix: Add the paragraph 22(aa) disclosure: judgements, segments aggregated and economic indicators assessed.

Worked examples

Example 1

Sundaram Foods Ltd has two operating segments reviewed by its CODM: Packaged Snacks (North) and Packaged Snacks (South). Both make similar snack products using the same process, sell to retail chains and distributors, and use the same distribution network. No special regulation applies. Long-term average gross margins are 28% and 27%. Can the segments be aggregated?

Show the solution
  1. Core principle: management reviews both, and combining them does not hide information users need. Assume it is consistent.
  2. Economic characteristics: margins of 28% and 27% are close, so they are similar.
  3. Criterion (a): same type of snack products, similar.
  4. Criterion (b): same production process, similar.
  5. Criterion (c): same class of customer, retailers and distributors, similar.
  6. Criterion (d): same distribution network, similar.
  7. Criterion (e): no special regulation, so not applicable.
  8. All applicable conditions are met.

Answer: Yes. Sundaram Foods may aggregate the two segments into one operating segment. It is permitted, not compulsory. The aggregated segment is then tested against the paragraph 13 thresholds, and the company must disclose its judgements and the economic indicators assessed under paragraph 22(aa).

Example 2

Kaveri Industries Ltd has Segment X (industrial pumps sold to factories through direct sales) and Segment Y (household pumps sold to consumers through dealers). Production processes are similar and long-term gross margins are close. Management wants to aggregate X and Y. Advise.

Show the solution
  1. Economic characteristics: margins are close, so this is satisfied.
  2. Criterion (a): both are pumps, but industrial and household products differ in nature and use. This is at best doubtful.
  3. Criterion (b): similar production processes, satisfied.
  4. Criterion (c): factories versus household consumers are different classes of customer. Not similar.
  5. Criterion (d): direct sales versus dealers are different distribution methods. Not similar.
  6. Paragraph 12 needs similarity in each criterion, and at least (c) and (d) fail.
  7. The majority test of paragraph 14 does not help, because it applies only to segments below the quantitative thresholds.

Answer: Aggregation is not permitted under paragraph 12. Similar margins and processes are not enough because the customer type and distribution method differ. X and Y should be assessed separately against the paragraph 13 thresholds. If either is below all thresholds, paragraph 14 could be considered for combining it with another small segment.

Exam tips

  • In MCQs, watch for options saying aggregation is mandatory or needs only a majority of criteria. Both are wrong for paragraph 12.
  • In case questions, write the five criteria as a short list and mark each similar or not similar. This earns step marks.
  • Always mention similar economic characteristics, with margins as the example, as a separate condition.
  • Keep paragraph 12 (aggregation of operating segments) and paragraph 14 (combining small segments) clearly apart in your answer.
  • End your answer with the paragraph 22(aa) disclosure requirement. Many students skip it.

Aggregation Criteria for Operating Segments: frequently asked questions

When can operating segments be aggregated under Ind AS 108?

When aggregation is consistent with the core principle, the segments have similar economic characteristics, and they are similar in products and services, production processes, customer type, distribution methods and, if applicable, regulatory environment. All of these must be met.

Is aggregation of operating segments compulsory?

No. Paragraph 12 says segments may be aggregated. The entity can choose to report them separately even when they qualify.

What is the difference between aggregation under paragraph 12 and paragraph 14?

Paragraph 12 needs similarity in each listed criterion and applies to any operating segments. Paragraph 14 applies only to segments that do not meet the quantitative thresholds. It needs similar economic characteristics and a majority of the paragraph 12 criteria.

What must an entity disclose if it aggregates segments?

Under paragraph 22(aa), it must disclose the management judgements made in applying the criteria. This includes a brief description of the aggregated segments and the economic indicators assessed to conclude they share similar economic characteristics.
