AS 17 Segment Reporting: Objective, Scope and Key Definitions

Updated 4 October 2026 · Fact-checked

AS 17 Segment Reporting requires listed enterprises, and those about to list securities, to disclose financial information by business and geographical segment. To solve questions, first check applicability, then classify each item using the definitions: segment revenue and expense include directly attributable and reasonably allocable items, and segment result is revenue minus expense.

Understand AS 17 Objective, Scope and Key Definitions

A company that sells several products in several regions gives one total profit figure in its statements. That hides which product or region earns well and which is risky. AS 17 fixes this. It makes the enterprise break its results into segments, so users can see past performance, judge risks and returns, and form better views about the enterprise as a whole.

Scope. AS 17 applies to enterprises whose equity or debt securities are listed on a recognised stock exchange in India, and to enterprises that are in the process of issuing equity or debt securities that will be listed. An enterprise that is not covered but chooses to disclose segment information must follow AS 17 for that disclosure. If one report contains both consolidated and parent-only statements, segment information is required only on the consolidated basis.

A business segment is a distinguishable component that provides an individual product or service, or a group of related products or services, and is subject to risks and returns different from other business segments. Look at the nature of products, production processes, type of customer, distribution methods and regulatory environment. A geographical segment is a distinguishable component that provides products or services within a particular economic environment and is subject to risks and returns different from other economic environments. Look at economic and political conditions, exchange control rules, currency risks and special risks.

The money definitions follow one logic. Segment revenue and segment expense include what is directly attributable to the segment plus a reasonable allocated share of common items. Both include dealings with other segments. Segment result is segment revenue minus segment expense. Segment assets are operating assets used by the segment. Segment liabilities are operating liabilities of the segment. Items that belong to the enterprise as a whole, or to financing and tax, stay out.

The tests that decide which segments are reportable (the 10% tests) are a separate topic. Here you need the purpose, who must apply the standard, and the exact meaning of each term.

Key rules to remember

Segment result: Segment result = Segment revenue − Segment expense; Calculated before interest expense (other than for financial enterprises), income tax, extraordinary items and enterprise-level costs.
Segment revenue includes: External sales + Inter-segment sales/transfers + Allocable revenue; Excludes extraordinary items, and interest, dividend income and gains on sale of investments or on extinguishment of debt, unless the segment's operations are primarily of a financial nature.
Segment expense includes: Direct operating expenses + Reasonable share of common operating expenses + Inter-segment charges; Excludes extraordinary items, interest expense, losses on sale of investments or extinguishment of debt (unless financial in nature), income tax expense, and general administrative or head-office expenses relating to the enterprise as a whole.
Segment assets: Operating assets used by the segment in its operating activities, directly attributable or allocable on a reasonable basis; Shown net of related allowances/provisions that are reported as offsets in the balance sheet. Excludes income tax assets.
Segment liabilities: Operating liabilities directly attributable or reasonably allocable; Excludes borrowings and income tax liabilities, unless the segment is financial in nature or interest is included in its result.
Scope rule: Listed, or in process of listing, equity or debt securities → AS 17 applies; Other enterprises that voluntarily disclose segment information must comply with AS 17 in that disclosure.
Reportable segment thresholds (preview): A segment is reportable if its revenue, result or assets is 10% or more of the total; Revenue: segment revenue (external plus inter-segment) is 10% or more of the total revenue of all segments, internal and external. Result is compared with the greater of combined profit of profit-making segments or combined loss of loss-making segments, in absolute amount. Assets are compared with total segment assets.

How to solve AS 17 Objective, Scope and Key Definitions questions

Use this order for any question on AS 17 objective, scope or definitions.

1Read what is asked: applicability, meaning of a term, classification of items, or a computation of segment result, assets or liabilities.
2For applicability, check whether the equity or debt securities are listed or about to be listed in India. If not, AS 17 is not mandatory, but voluntary disclosure must follow it.
3For segment identification, decide the basis. Use products or services and customer type for business segments. Use economic environment, currency and political risk for geographical segments. State that the segment must have different risks and returns.
4Classify each item given. Put it in segment revenue or expense only if it is operating, directly attributable or reasonably allocable.
5Drop items that never belong to a segment: extraordinary items, income tax, enterprise-level head-office costs, and interest or investment gains for non-financial enterprises.
6Include inter-segment revenue and expense. These are part of segment revenue and expense even though they cancel on consolidation.
7Compute segment result as revenue minus expense. Show each line so you earn step marks.
8Write a one-line conclusion naming the standard and the reason, for example 'interest is excluded as the segment is not financial in nature'.

Quickest way: Include-or-exclude filter for MCQs and short answers

When to use it: Use when you get a list of items and must find segment revenue, expense or result, or when an MCQ asks which item is excluded.

Ask first: is it operating and about the segment? If yes, include it.
Then check four exclusions: extraordinary items, interest or investment gains/losses, income tax, and head-office costs for the whole enterprise. If the enterprise is not financial, cut them.
Always keep inter-segment items of an operating nature (such as transfers of goods or services) inside segment revenue and expense.
For applicability MCQs, look only for listed or about-to-list status. Size and turnover do not decide it.
In written answers, write the definition in one line, show a small list of inclusions and exclusions, then the answer. No negative marking applies to MCQs, so attempt every one.

Common mistakes in AS 17 Objective, Scope and Key Definitions

Saying AS 17 applies to every company above a certain size.
Students mix AS 17 with the general applicability of Accounting Standards by size.
Fix: Remember the AS 17 trigger: listed securities or securities in the process of being listed. Others may disclose voluntarily, and then must follow the standard.
Leaving out inter-segment transfers from segment revenue.
Students think only external sales are revenue.
Fix: Segment revenue includes revenue from external customers and from transactions with other segments.
Deducting income tax or interest when computing segment result.
Students copy the profit and loss account layout.
Fix: Exclude tax, extraordinary items, and interest for non-financial enterprises. Segment result is operating in nature.
Allocating all head-office expenses to segments.
Students want every rupee of expense shown.
Fix: Allocate only costs that relate to the segment and can be allocated on a reasonable basis. General enterprise-level costs stay unallocated.
Confusing business and geographical segments by using the wrong test.
Both are called segments, so the bases blur together.
Fix: Business segment: products, processes, customers, distribution, regulation. Geographical segment: economic environment, political conditions, currency, exchange control. Always state the different risks and returns.
Including borrowings in segment liabilities of a manufacturing segment.
Students treat all liabilities as segment liabilities.
Fix: Segment liabilities are operating liabilities. Borrowings and tax liabilities are excluded unless the segment is financial in nature or the related interest is in its result.

Worked examples

Example 1

Alpha Ltd is a manufacturing company. For its Segment X, the following data are available for the year: external sales ₹50,00,000; transfers to Segment Y ₹10,00,000; interest income on general investments ₹2,00,000; extraordinary gain ₹1,00,000; direct operating expenses ₹38,00,000; interest expense ₹1,50,000; income tax ₹3,00,000; general head-office expenses of the enterprise (not allocable) ₹4,00,000. Compute segment revenue, segment expense and segment result of Segment X under AS 17.

Show the solution

Segment revenue includes external sales ₹50,00,000 and inter-segment transfers ₹10,00,000 (an operating transaction with another segment). Total = ₹60,00,000.
Interest income on general investments (₹2,00,000) is excluded because the segment's operations are not primarily of a financial nature.
The extraordinary gain (₹1,00,000) is excluded from segment revenue.
Segment expense includes only direct operating expenses of ₹38,00,000.
Interest expense (₹1,50,000), income tax (₹3,00,000) and general head-office expenses (₹4,00,000) are excluded.
Segment result = ₹60,00,000 − ₹38,00,000 = ₹22,00,000.

Answer: Segment revenue ₹60,00,000; segment expense ₹38,00,000; segment result ₹22,00,000.

Example 2

State with reasons which of the following must apply AS 17: (a) P Ltd, whose equity shares are listed on a recognised stock exchange in India; (b) Q Ltd, an unlisted company that is in the process of issuing debentures which will be listed; (c) R Ltd, an unlisted company with no plan to list; (d) S Ltd, an unlisted company that decides to give segment information in its annual report.

Show the solution

AS 17 applies to enterprises whose equity or debt securities are listed on a recognised stock exchange in India, and to those in the process of issuing securities that will be listed.
P Ltd has listed equity shares. AS 17 applies.
Q Ltd is issuing debentures that will be listed. It is in the process of listing. AS 17 applies.
R Ltd is neither listed nor in the process of listing. AS 17 is not mandatory for it.
S Ltd is not required to disclose, but it chooses to. An enterprise that voluntarily discloses segment information must comply with AS 17 for that disclosure.

Answer: AS 17 is mandatory for P Ltd and Q Ltd. It is not mandatory for R Ltd. S Ltd must follow AS 17 for the segment information it chooses to disclose.

Exam tips

Learn the scope rule word for word: listed, or in the process of issuing securities to be listed. It is a favourite short question and a common MCQ.
Memorise the exclusions from segment revenue and expense as a short list. Questions often ask 'which item is not part of segment expense'.
In computation questions, show a mini-statement: revenue lines, expense lines, then result. Examiners give marks for each correct inclusion and exclusion.
When asked to distinguish business and geographical segments, give the factors for each and end with 'different risks and returns'.
Read the data carefully for hints like 'financial in nature'. They change whether interest is included.

Practice questions from AS 17 Segment Reporting

AS 17 Objective, Scope and Key Definitions: frequently asked questions

Which enterprises must follow AS 17?

Enterprises whose equity or debt securities are listed on a recognised stock exchange in India, and those in the process of issuing such securities for listing. Other enterprises that voluntarily give segment information must follow AS 17 in doing so.

What is the difference between a business segment and a geographical segment?

A business segment is based on products or services and their risks and returns. A geographical segment is based on the economic environment in which products or services are provided. Each is a distinguishable component with risks and returns different from other segments of the same type.

Is inter-segment revenue part of segment revenue?

Yes. Segment revenue includes revenue from external customers and from transactions with other segments. The same applies to segment expense for inter-segment charges.

Is income tax included in segment expense?

No. Income tax expense is excluded from segment expense, and income tax assets and liabilities are excluded from segment assets and liabilities.
