Ind AS 21 Scope, Objective and Key Definitions

Updated 11 October 2026 · Fact-checked

Ind AS 21 tells you how to account for foreign currency transactions and foreign operations, and how to translate financial statements into a presentation currency. Solve questions by first fixing the functional currency, then classifying each item as monetary or non-monetary, then picking the right rate: closing rate, transaction-date rate or fair-value-date rate.

Understand Ind AS 21 Scope, Objective and Key Definitions

Ind AS 21 deals with two situations. First, an entity enters into transactions or has balances in a currency other than its own functional currency. Second, an entity has a foreign operation, or presents its financial statements in a currency other than its functional currency. The standard sets out which exchange rate to use and where the resulting exchange difference goes.

Everything starts with the functional currency. The standard defines it as the currency of the primary economic environment in which the entity operates. A foreign currency is any currency other than the functional currency. So the same US dollar is a foreign currency for an Indian company whose functional currency is the rupee, but not for a US-based subsidiary whose functional currency is the dollar.

The presentation currency is the currency in which the financial statements are presented. It may be different from the functional currency. Translating from functional to presentation currency is a separate exercise from recording foreign currency transactions, and it follows different rules.

A foreign operation is a subsidiary, associate, joint arrangement or branch of the reporting entity whose activities are based or conducted in a country or currency other than those of the reporting entity. The test is the country or currency of the activities, not the legal form.

The key classification is monetary items: units of currency held, and assets and liabilities to be received or paid in a fixed or determinable number of units of currency. Cash, receivables, payables and loans are typical examples. Items like PPE, inventory and advances that will be settled by goods or services are non-monetary. This split decides the rate you apply at each reporting date.

Three rate terms matter. The spot exchange rate is the rate for immediate delivery. The closing rate is the spot rate at the end of the reporting period. An exchange difference arises from translating a given number of units of one currency into another at different exchange rates. The standard also requires an entity to estimate the spot rate when a currency is not exchangeable into another (paragraph 19A), with the objective of reflecting the rate at which an orderly exchange transaction would take place between market participants under prevailing economic conditions.

Key rules to remember

Functional currency: Functional currency = currency of the primary economic environment in which the entity operates; Paragraph 8 definition. Foreign currency means any currency other than this.
Monetary items: Monetary item = units of currency held + assets and liabilities to be received or paid in a fixed or determinable number of units of currency; Cash, trade receivables, trade payables and loans are monetary. The test is a fixed or determinable amount of currency.
Rates at each reporting date (para 23): Monetary items → closing rate | Non-monetary at historical cost → rate at transaction date | Non-monetary at fair value → rate at date fair value was measured; This is the core translation rule that definitions feed into.
Exchange difference: Exchange difference = foreign currency units translated at one rate − same units translated at another rate; It is the result of translating the same units at different rates.
Net investment in a foreign operation: Net investment = reporting entity's interest in the net assets of that operation; Paragraph 8 definition.
Change in functional currency (para 37): Translate all items at the rate on the date of change; effect is prospective; Translated non-monetary amounts become their historical cost. Earlier OCI translation differences are not reclassified until disposal of the operation.

How to solve Ind AS 21 Scope, Objective and Key Definitions questions

Use this sequence for any scope or definition based question, whether MCQ or case study.

1Identify the reporting entity and decide its functional currency from the primary economic environment in which it operates.
2Mark every other currency as a foreign currency. Check whether any group entity is a foreign operation (activities in a different country or currency).
3Classify each balance as monetary or non-monetary. Ask: will it be settled in a fixed or determinable number of currency units?
4For non-monetary items, note the measurement basis: historical cost or fair value.
5Pick the rate: closing rate for monetary items, transaction-date rate for historical cost items, fair-value-date rate for fair value items.
6Separate the two exercises: recording foreign currency transactions in functional currency, versus translating into a presentation currency.
7State the conclusion in the standard's terms, quoting the definition where it helps, and give a clear final answer.

Quickest way: Three-question screen

When to use it: For 2-mark MCQs and short case-scenario questions where you have about two to three minutes.

Q1: What is the functional currency? Anything else is foreign currency.
Q2: Is the item settled in a fixed or determinable amount of currency? If yes, monetary: closing rate.
Q3: If non-monetary, is it at historical cost (transaction-date rate) or fair value (rate when fair value was measured)?
Eliminate options that mix up presentation currency with functional currency.

Common mistakes in Ind AS 21 Scope, Objective and Key Definitions

Treating the presentation currency as the functional currency.
Both are currencies of the financial statements, so they look alike, and many Indian companies use the rupee for both.
Fix: Fix the functional currency from the primary economic environment. Presentation currency is only a choice about how statements are shown.
Classifying advances paid or received as monetary items.
Advances involve cash, so students assume a fixed amount is receivable or payable.
Fix: Advance consideration for goods or services creates a non-monetary asset or liability. Appendix B applies to such advances, so check it before applying the closing rate.
Applying the closing rate to PPE or inventory.
Students remember closing rate as the rule for foreign currency balances.
Fix: Closing rate is for monetary items. Historical cost non-monetary items use the transaction-date rate.
Confusing spot rate and closing rate.
Both are spot rates, so the terms seem interchangeable.
Fix: Spot rate is the rate for immediate delivery on any date. Closing rate is the spot rate at the end of the reporting period.
Calling a foreign subsidiary's currency its foreign currency in its own books.
Students view everything from the parent's point of view.
Fix: Foreign currency is defined relative to each entity's own functional currency. Check each entity separately.
Thinking a change in functional currency is applied retrospectively.
Other changes in policy are often retrospective.
Fix: Under paragraph 37 the change is accounted for prospectively, using the rate at the date of the change.

Worked examples

Example 1

Bharat Textiles Ltd, whose functional currency is the Indian rupee, has these balances at 31 March: cash in an Indian bank, trade receivable of USD 20,000 from a US customer, machinery imported earlier for USD 50,000 carried at cost, and an advance paid to a supplier for goods to be delivered. Classify each item and state the rate used for the first three.

Show the solution

Functional currency is the rupee. The US dollar is therefore a foreign currency.
Cash in an Indian bank is units of currency held, so it is monetary. It is already in rupees.
The USD 20,000 receivable is to be received in a fixed number of currency units, so it is monetary. Use the closing rate.
The imported machinery is a non-monetary item at historical cost. Use the exchange rate at the date of the transaction that recognised it.
The advance to the supplier will be settled by receipt of goods, not currency. It is a non-monetary asset, and Appendix B on advance consideration applies.

Answer: Cash and the USD receivable are monetary (the receivable at the closing rate). Machinery is non-monetary at historical cost, translated at the transaction-date rate. The advance is a non-monetary asset.

Example 2

Which of the following is a foreign operation of Sagar Industries Ltd (India)? (A) A wholly owned subsidiary in Dubai whose activities are conducted in UAE dirhams. (B) A branch in Chennai selling in rupees. (C) An Indian subsidiary that merely holds a USD loan. (D) A division in Pune that exports goods invoiced in dollars. Give the correct option with reasoning.

Show the solution

Paragraph 8 defines a foreign operation as a subsidiary, associate, joint arrangement or branch whose activities are based or conducted in a country or currency other than those of the reporting entity.
Option A is a subsidiary with activities in the UAE and in dirhams. It meets the definition.
Option B is a branch, but its activities are in India and in rupees. It does not qualify.
Option C has a USD loan, but its activities are in India. A foreign currency liability does not make an entity a foreign operation.
Option D is a division, not a subsidiary, associate, joint arrangement or branch. Its activities are based in India, and invoicing in dollars creates foreign currency transactions only.

Answer: Option A. Only the Dubai subsidiary has activities based and conducted in another country and currency.

Exam tips

In MCQs, the trap is usually the definition wording. Learn the paragraph 8 definitions almost word for word.
For case scenarios, write the functional currency first. Every later answer depends on it.
Always state both the classification (monetary or non-monetary) and the rate. Marks are given for each.
Do not mention MEIS-style historical items or other standards unless asked. Stay within Ind AS 21 terms.
If a question mentions a currency that cannot be exchanged, recall that the standard requires an estimated spot rate that reflects an orderly transaction between market participants.

Practice questions from The Effects of Changes in Foreign Exchange Rates (Ind AS 21)

Ind AS 21 Scope, Objective and Key Definitions: frequently asked questions

What is the difference between functional currency and presentation currency?

Functional currency is the currency of the primary economic environment in which the entity operates. Presentation currency is the currency in which the financial statements are presented. They can be the same or different.

Which items are monetary under Ind AS 21?

Units of currency held, and assets and liabilities to be received or paid in a fixed or determinable number of units of currency. Cash, receivables, payables and loans are common examples. PPE, inventory and advances for goods or services are non-monetary.

What is the difference between spot rate and closing rate?

Spot rate is the exchange rate for immediate delivery. Closing rate is the spot rate at the end of the reporting period. So the closing rate is one particular spot rate.

What is an exchange difference?

It is the difference that results from translating a given number of units of one currency into another currency at different exchange rates. It arises, for example, when a receivable is recorded at one rate and measured later at the closing rate.
