AS 17 Segment Reporting: A Practitioner Guide for FY 2026-27
AS 17 (Segment Reporting) is the mandatory Indian Accounting Standard that requires enterprises to disclose financial information by business and geographical segments in their financial statements.
The Institute of Chartered Accountants of India (ICAI) issued AS 17 under the Companies (Accounting Standards) Rules, 2006. The Ministry of Corporate Affairs (MCA) reaffirmed its applicability through the Companies (Accounting Standards) Rules, 2021. The standard became effective from 1 April 2001 for Level I enterprises and later extended to all qualifying entities. It superseded the earlier ICAI standard issued in October 2000.
For FY 2026-27, AS 17 remains highly relevant for Level I enterprises and all listed companies not covered under Ind AS. For mid-market diversified businesses, correct segment identification, especially between business and geographical segments, remains a frequent audit focus and a common source of error.
AS 17 at a Glance
AS 17 requires enterprises to present segment-wise financial information, by both business line and geography, to enhance transparency for users. Its primary users are Level I companies and listed entities preparing financial statements under the Accounting Standards framework.

What is AS 17: Segment Reporting?
AS 17 defines how an enterprise must report financial results by business segment and geographical segment within its annual accounts. The standard's core principle is that users should see how different lines of business or regions contribute to overall performance and risk.
ICAI introduced this standard to address information asymmetry faced by investors and lenders when only consolidated results were available. Its adoption aligned Indian GAAP with international practices set by IFRS and US GAAP on segment reporting.
Statutory auditors, CFOs of listed companies using the Accounting Standards framework, CA Final students, and finance teams preparing statutory reports are the primary users of this standard.
Objective of AS 17
The objectives of AS 17 are:
- Establish principles for reporting financial information about the different types of products and services an enterprise produces and the different geographical areas in which it operates.
- Provide information that helps users to better understand the performance of the enterprise, better assess its risks and returns, and make more informed judgements about the enterprise as a whole.
- Distinguish between business segments and geographical segments, with primary and secondary reporting formats.
By requiring detailed segment disclosures, AS 17 supports the “true and fair view” principle enshrined in Section 129 of the Companies Act, 2013. This enables stakeholders, including regulators, to assess whether an enterprise’s reported results accurately reflect its underlying activities.
Who Must Apply AS 17?
Entities covered
AS 17 applies as follows:
| Entity Type | Applicability |
|---|---|
| Level I Enterprises | Mandatory |
| Level II Enterprises | Recommended |
| Level III Enterprises | Recommended |
| Listed Companies (AS regime) | Mandatory; SEBI requirements also apply |
| Ind AS Companies | Not applicable, Ind AS 108 applies |
Level I includes listed entities or those meeting size criteria notified by MCA. Both standalone and consolidated financial statements are covered if prepared under Indian GAAP/AS.
Scope exclusions
Exclusions under AS 17:
- Where standalone and consolidated financial statements are presented together, segment information is given only in consolidated context with cross-reference.
When the standard does not apply
If an entity migrates to Ind AS based on MCA’s roadmap or falls within Ind AS Phase I/II/III thresholds, it must apply Ind AS 108 instead of AS 17. Entities presenting both standalone and consolidated accounts together provide segment disclosures only at consolidated level as per this standard.
Key Definitions under AS 17
| Term | Definition |
|---|---|
| Business segment | Distinct part providing individual or related products/services with separate risks/returns. |
| Geographical segment | Distinct part operating within a specific economic environment with unique risks/returns. |
| Reportable segment | Business or geographical segment requiring disclosure as per threshold criteria in AS 17. |
| Primary segment | Main format, business or geographical, based on dominant risks/returns source. |
| Secondary segment | Other format reported with less detail than primary segment. |
| Segment revenue | Revenue directly attributable or reasonably allocable to a specific segment (including inter-segment). |
Recognition and Measurement under AS 17
When to recognise
An enterprise must identify reportable segments if they meet quantitative thresholds specified by Para 27-29 of AS 17:
Segment revenue is at least ten percent of total revenue.
Segment result (profit/loss absolute value) is at least ten percent of combined result.
Segment assets are at least ten percent of total assets.
If total external revenue from reportable segments is less than seventy-five percent of total enterprise revenue, additional segments must be designated as reportable until this threshold is met.
The entity determines whether business or geographical segmentation forms its primary reporting format based on which type exposes it to greater risks and returns.
Initial measurement
Segment revenue, expense, result, assets, and liabilities are measured using accounting policies consistent with those applied in preparing overall financial statements (Para 25). Allocations between segments must be made on a reasonable basis reflecting actual use or benefit derived by each segment.
Inter-segment transactions, including transfers, are included in both revenue calculations but eliminated at enterprise level during consolidation.
**Segment Result Formula:**
Segment Result = Segment Revenue, Segment Expenses
>
Where both items include amounts directly attributable or reasonably allocated to that segment.
Subsequent measurement
At each annual reporting date:
- Present comparative information for prior periods.
- Disclose changes in composition or structure of reported segments.
- Restate prior period data where practicable if segments change.
- Disclose basis for inter-segment pricing arrangements.
- Reconcile aggregate amounts disclosed as per segments with corresponding totals in statutory accounts (Para 52).
Inter-segment eliminations must be shown separately so users can reconcile totals across notes/disclosures.
Risks and Rewards Approach - Primary and Secondary Segments
AS 17 mandates a “risks-and-rewards” approach distinct from Ind AS 108’s management approach:
- Identify primary format, business or geography, based on which drives overall risk/return profile.
- Secondary format receives limited disclosure.
For example:
- A multi-product manufacturer operating mainly within India would use business as primary; geography as secondary.
- An IT services exporter exposed mainly to overseas market risks would use geography as primary; business as secondary.
Primary segments require full disclosure, including revenue (external/inter-segment), results, assets/liabilities/capex/depreciation/non-cash expenses per Para 39(c)-(f). Secondary only needs revenue/assets/capex split per region/business line.
This dual-format model differentiates Indian GAAP from Ind AS/IFRS where only one format is required based on internal management reporting structure.
Worked Examples on AS 17
Example 1: Business primary, geographical secondary
Krishna Steel Industries operates two business lines, steel manufacturing (Rs 800 crore revenue) and aluminium products (Rs 270 crore). Both face distinct risks but operate across similar regions within India; thus business segmentation dominates.
Computation Table
| Segment | Revenue (Rs crore) | % Total Revenue |
|---|---|---|
| Steel | 800 | 74.8% |
| Aluminium | 270 | 25.2% |
Both meet/exceed ten percent threshold; both are reportable segments under Para 27-29.
Combined reportable segment revenue exceeds seventy-five percent test for single enterprise context.
Journal Entry
No accounting entry arises from identification/disclosure; impact appears solely in detailed notes:
- Business primary note discloses revenue/result/assets/liabilities/capex/depreciation/non-cash expenses per steel/aluminium line.
- Geographical secondary note presents India vs Export split for revenue/assets/capex only.
Example 2: Geographical primary
Sundaram Software provides software services exclusively but operates across three major regions:
India (Rs 200 crore), USA (Rs 800 crore), Europe (Rs 400 crore). Regional currency/competitive risks dominate over product diversity; thus geography is primary segmentation basis.
Computation Table
| Region | Revenue (Rs crore) | % Total Revenue |
|---|---|---|
| India | 200 | 14% |
| USA | 800 | 57% |
| Europe | 400 | 29% |
All three exceed ten percent threshold; all are reportable geographic segments.
Combined regional revenues cover one hundred percent total; no further designation required.
Business segmentation not required beyond single line item due to single product focus.
Journal Entry
No accounting entry arises; impact reflects only through enhanced note disclosures:
- Geographical primary note details region-wise revenue/result/assets/liabilities/capex/depreciation/non-cash expenses.
- Business secondary note limited due to single service line, disclosure minimal beyond aggregate numbers.
Disclosure Requirements under AS 17
Schedule III to the Companies Act, 2013, requires companies to present a true and fair view of their financial position. AS 17 mandates granular segment disclosures to ensure users can assess an enterprise’s risks and returns by business line and geography. Proper segment reporting supports transparency, comparability, and regulatory compliance.
| Item | Requirement | Para Reference |
|---|---|---|
| Identification of segments | Types of products and services, composition of each business segment, reasons for segment structure | Para 38 |
| Primary segment - revenue | External revenue, inter-segment revenue, total revenue per segment | Para 39(a) |
| Primary segment - result | Segment result (segment revenue less segment expenses) | Para 39(b) |
| Primary segment - other | Segment assets, segment liabilities, capital expenditure, depreciation, non-cash expenses | Para 39(c)-(f) |
| Secondary segment | Less detailed - revenue, assets, capex | Para 47-51 |
| Inter-segment transfers | Basis of inter-segment pricing | Para 50 |
| Reconciliation | Reconciliation of segment information with enterprise totals | Para 52 |
Auditors must verify that all AS 17 disclosures are complete and consistent with the statutory accounts as part of their SA 700 reporting responsibility.
Common Mistakes & Industry-Specific Considerations
Common errors auditors flag
- Identifying primary segments incorrectly, using business as primary when geographical risks dominate or vice versa.
- Failing to apply the 10% threshold and 75% revenue test correctly.
- Inadequate secondary segment disclosure in financial statements.
- Missing disclosure of inter-segment pricing basis.
- Confusing the AS 17 risks-and-rewards approach with Ind AS 108’s management approach.
- Aggregating segments without a reasonable basis.
Industry application notes
Mid-market diversified businesses often have business as the primary format with multiple segments. Family-owned groups must carefully identify which business drives overall risk and return; this determines the correct primary format for AS 17 compliance.
In IT services companies applying AS standards (not Ind AS), geographical segmentation is common due to regional currency and competitive risks. SEBI listing requirements may add further disclosure layers beyond AS 17.
Listed entities following the Accounting Standards regime must strictly comply with Paras 38-40 for disclosure. Segment information is sometimes included in management discussion sections but must always reconcile precisely to the formal disclosures required by AS 17.
AS 17 vs Ind AS 108 vs IFRS: Key Differences
AS 17 Segment Reporting follows a dual-format “risks and rewards” approach distinct from Ind AS 108 (Operating Segments) and IFRS 8 (Operating Segments). The table below summarises key differences in approach, identification, measurement basis, and disclosure requirements:
| Aspect | AS | Ind AS | IFRS |
|---|---|---|---|
| Approach | Risks and rewards approach | Management approach (CODM) | Management approach |
| Primary/secondary format | Both required (different detail) | Single format | Single format |
| Segment identification | By predetermined classification | By internal management structure | By internal management structure |
| Measurement basis | Same as enterprise accounting | Internal management measures permitted | Same as Ind AS |
| Entity-wide disclosures | Implicit in dual format | Explicit (Para 31-34) | Explicit |
India has carved out a stricter requirement under AS 17 by mandating both primary and secondary formats based on risks/returns. Ind AS 108 aligns fully with IFRS 8’s “management approach”, focusing on how segments are reported internally to the chief operating decision maker.

Frequently Asked Questions (FAQs)
All Level I enterprises preparing financial statements under Indian Accounting Standards must comply with AS 17. This includes listed companies not covered by Ind AS. Level II and III enterprises are recommended but not mandated to follow it.
The primary segment is determined by whether business lines or geography drive overall risks and returns. The secondary format receives less detailed disclosure. For example, a manufacturing company may use business as primary and geography as secondary if product risk dominates.
AS 17 uses a “risks-and-rewards” model requiring both primary and secondary formats. Ind AS 108 follows a “management approach”, reporting segments based on internal information provided to decision makers. Measurement bases also differ between the two standards.
A reportable segment meets the ‘10% test’ if its revenue, result (absolute value), or assets are at least ten percent of corresponding enterprise totals. If reportable segments together contribute less than seventy-five percent of external revenue, additional segments become reportable until this threshold is met.
An entity identifies business segments based on products or services subject to different risks/returns. Geographical segments reflect operations within distinct economic environments. The dominant source of risk determines which is primary under Para 27-29 of AS 17.
Segment result equals segment revenue minus expenses directly attributable or reasonably allocated to that segment. Both items follow accounting policies consistent with those used in preparing overall financial statements for comparability purposes.
Inter-segment transfers are transactions between two or more reportable segments within an enterprise. Their revenues are included in each relevant segment’s results but eliminated at enterprise level during consolidation. The basis for pricing such transfers must be disclosed per Para 50.
Reconciliation ensures that users can match aggregate amounts disclosed for all segments back to totals reported in statutory financial statements. This prevents double counting or omission due to inter-segment eliminations (Para 52).
Aggregation is permitted only if combined segments share similar economic characteristics and meet criteria set out by the standard. Arbitrary aggregation without reasonable basis violates both the letter and spirit of AS 17 requirements.
No. While Schedule III mandates certain disclosures aligned with major accounting standards like AS 17, full compliance requires meeting all detailed presentation rules specified in both Schedule III and relevant ICAI pronouncements.
