Ind AS 21: Why Foreign Exchange Rates Matter in Financial Statements

Imagine a company headquartered in Mumbai that buys raw material from Germany, sells finished goods in the United States, and has investors in Japan. Which currency should it use to record transactions? Which currency should it use to present its annual report? These two questions sit at the very heart of Ind AS 21 — The Effects of Changes in Foreign Exchange Rates, and they are tested heavily in the CA Final Financial Reporting paper.

Let us build the concept from the ground up, the way we do in class — step by step, with logic first.

What Is Functional Currency?

Functional currency is the currency of the primary economic environment in which an entity operates. Think of it as the currency your business actually breathes in — the one that drives your pricing, your costs, and your cash flows day to day.

Ind AS 21 gives a hierarchy of indicators to identify functional currency:

Primary Indicators (more decisive)

  • The currency that mainly influences sales prices for goods and services.
  • The currency of the country whose competitive forces and regulations mainly determine those sales prices.
  • The currency that mainly influences labour, material, and other costs.

Secondary Indicators (supporting evidence)

  • The currency in which funds from financing activities are generated.
  • The currency in which receipts from operating activities are usually retained.

Key logic: If primary indicators are mixed or unclear, management exercises judgement and looks at secondary indicators. Functional currency is a fact, not a choice — you determine it; you do not select it for convenience.

A Simple Worked Logic

Suppose ABC Ltd is an Indian subsidiary of a US parent. Its sales are billed in USD, its raw material costs are negotiated and settled in USD, and its bank loans are drawn in USD. Even though it is registered in India and its staff are paid in INR, the dominant economic environment is the US dollar. The functional currency would most likely be USD, not INR.

Now change one variable: if the same company sells exclusively to Indian customers at INR-denominated prices and its major costs are INR-linked, INR becomes the functional currency despite the US parent.

What Is Presentation Currency?

Presentation currency is simply the currency in which the entity presents its financial statements. This is a choice — management can select any currency for presentation purposes.

Most Indian companies present in INR because that is convenient for Indian stakeholders. But an Indian company listed on a foreign exchange might choose to present in USD for the benefit of international investors.

Bottom line: Functional currency = determined by facts. Presentation currency = chosen by management.

Translation: When Functional ≠ Presentation Currency

When a company's functional currency differs from its presentation currency, it must translate its entire financial statements. Ind AS 21 prescribes the following translation rules:

| Item | Exchange Rate to Use | |---|---| | Assets and Liabilities | Closing rate (balance sheet date) | | Income and Expenses | Rate at the date of the transaction (or average rate if it approximates actual rates) | | Equity items (share capital, opening reserves) | Historical rate |

The difference that arises from translating income/expenses at transaction-date rates but assets/liabilities at closing rates does not go to profit or loss. It is parked in Other Comprehensive Income (OCI) under a component called the Foreign Currency Translation Reserve (FCTR). This protects the profit or loss from random exchange-rate noise that is purely a translation effect.

Recording Foreign Currency Transactions — The Basics

Before translation even comes into the picture, the entity must record individual foreign currency transactions correctly in its functional currency:

  • Initial recognition: Use the spot rate on the transaction date.
  • Monetary items (trade receivables, payables, loans) at the balance sheet date: Retranslate at the closing rate; the resulting exchange difference goes to profit or loss.
  • Non-monetary items measured at historical cost: Use the rate on the transaction date — no retranslation.
  • Non-monetary items measured at fair value: Use the rate when the fair value was determined.

Quick Worked Logic

XYZ Ltd (functional currency INR) purchases goods worth USD 10,000 on 1 March. On that date, 1 USD = ₹83. On 31 March (year-end), 1 USD = ₹85. The payable is monetary.

  • Recorded initially: ₹8,30,000
  • Restated at year-end: ₹8,50,000
  • Exchange loss of ₹20,000 → Profit or Loss (not OCI)

Had this been a prepaid expense (non-monetary), no retranslation would happen — it stays at ₹8,30,000.

Common Exam Pitfalls

  • Confusing functional and presentation currency — remember, one is a fact, the other is a choice.
  • Putting translation differences in P&L — translation differences on translating a foreign operation go to OCI/FCTR, not P&L.
  • Using wrong rate for non-monetary items — historical cost items always use the historical rate.
  • Assuming the parent's currency is always the subsidiary's functional currency — always apply the indicators; never assume.

FAQs

Q1. Can a company change its functional currency? Yes, but only if there is a genuine change in the underlying economic environment — not for accounting convenience. The change is applied prospectively from the date of the change.

Q2. Is FCTR ever recycled to profit or loss? Yes. When a foreign operation is disposed of (fully or partially, in certain cases), the accumulated FCTR related to that operation is reclassified from OCI to profit or loss as a reclassification adjustment.

Q3. What if a company operates in a hyperinflationary economy? Ind AS 21 read with Ind AS 29 (Financial Reporting in Hyperinflationary Economies) applies. The financial statements are first restated under Ind AS 29 and then translated at the closing rate. Verify the latest ICAI study material for current guidance on this interaction.

Ind AS 21 is one of those standards where the concept is straightforward once you separate the fact-based determination of functional currency from the choice-based presentation currency. Build that distinction firmly, and the rest — transaction recording, retranslation, FCTR — will fall into place naturally.
