Consolidating Foreign Subsidiaries Under IFRS: IAS 21 Translation Guide

Consolidating a Foreign Subsidiary

Consolidating a foreign subsidiary is a two-stage exercise. The subsidiary keeps its books in its own functional currency — the currency of the primary economic environment in which it operates — so those statements are first translated into the group's presentation currency, then consolidated using the same IFRS 10 procedures as for a domestic subsidiary. IAS 21 governs the translation with three rules:

1. Assets and liabilities are translated at the closing rate at the reporting date.
2. Income and expenses are translated at the exchange rates on the dates of the transactions, in practice an average rate for the period.
3. Every resulting exchange difference is recognised in other comprehensive income and accumulated in the foreign currency translation reserve.

Because the statement of financial position is translated at one rate and profit or loss at another, the translated figures no longer balance. The translation reserve is the balancing amount, and the rest of this guide concerns how much arises and who owns it.

The Closing Rate Method

IAS 21 paragraph 39 prescribes the mechanics, and they apply to every foreign operation of the group in the same way.

Two features of the method deserve emphasis.

Non-monetary assets move. Inventory, property, plant and equipment, right-of-use assets, intangibles and deferred tax all go to the closing rate — the opposite of the transaction rule, where a non-monetary item measured at historical cost stays permanently at the rate on the date it was recognised.

Equity is not covered by paragraph 39. IAS 21 is silent on the rate for equity, so the consolidation decides: share capital and pre-acquisition reserves must be carried at the acquisition-date rate or the investment will not eliminate against them.

Where the difference comes from

The difference is a balancing figure, but decomposing it is the most reliable way to prove a translation correct.

The reserve measures how the group's net investment has been restated, not a gain or loss the group has made, and nothing is realised until the operation is sold. IAS 21 paragraph 41 gives the reasoning: the differences have little or no direct effect on operating cash flows.

Translate First, Consolidate Second

The sequence matters, because the two stages produce different pieces of the translation reserve.

1. Translate the subsidiary's own trial balance into the presentation currency. Assets and liabilities at the closing rate, income and expenses at average or transaction rates, share capital and pre-acquisition retained earnings at the acquisition-date rate. The balancing figure is the translation reserve on the subsidiary's own net assets.
2. Consolidate the translated trial balance exactly as for a domestic subsidiary:
   • eliminate the investment against acquisition-date equity;
   • recognise goodwill and the non-controlling interest;
   • recognise the acquisition-date fair value adjustments and their deferred tax;
   • bring in post-acquisition reserves and attribute the non-controlling interest's share;
   • eliminate intragroup balances, transactions and unrealised profit.
3. Add the translation reserve on the group-level adjustments. Fair value adjustments, their subsequent depreciation and their deferred tax exist only in the consolidated financial statements, so the subsidiary's translated trial balance contains none of their exchange effect. Goodwill is in the same position.

The translated trial balance balances to a reserve computed on carrying amounts in the subsidiary's own books, so every consolidation journal that changes an asset or liability of the foreign operation needs its own entry to the reserve. Where the statements are instead built from an analysis of the subsidiary's equity, the fair value adjustments sit inside the equity being translated and a single balancing reserve captures their effect. Both routes reach the same total.

Example: Translating a Subsidiary

The same group runs through the rest of this guide. P, a UK parent presenting in sterling, acquired 80% of S on 1 January 20X4. S trades, funds itself and retains its cash in the United States, so its functional currency is the US dollar. S's land was carried at $1,200 against a fair value of $1,700 at acquisition, and deferred tax at 20% applies to the difference.

Translating profit or loss

S trades evenly and the rate moved steadily, so every line goes at the 20X4 average of 0.75. Revenue of $4,000 becomes 3,000, total expenses of $3,500 become 2,625, and profit for the year of $500 becomes 375.

Translating the statement of financial position

Assets and liabilities move to the closing rate of 0.80, while share capital and the retained earnings brought forward stay at 0.70. The reserve is the balancing amount.

The reserve of 275 proves out against its two causes: opening net assets of $2,500 multiplied by the 0.10 movement in the rate gives 250, and profit of $500 translated at 0.75 but held at 0.80 gives a further 25.

The fair value adjustment carries its own difference

The land adjustment and its deferred tax exist only at group level, so they are absent from the trial balance above. Both are assets and liabilities of the foreign operation, retranslated at 0.80.

The group's translation difference on S's net assets for 20X4 is therefore 315 — 275 on S's own carrying amounts plus 40 on the fair value adjustment, and the figure the analysis of equity below produces directly. Land carries no subsequent charge, so the adjustment is simply retranslated each year. An adjustment to a depreciable asset also produces a difference between the additional depreciation, translated at the average rate, and the accumulated additional depreciation, translated at the closing rate; that difference belongs in the reserve as well.

Goodwill, Fair Value Adjustments and NCI

IAS 21 paragraph 47 treats goodwill arising on the acquisition of a foreign operation, and fair value adjustments to its assets and liabilities, as assets and liabilities of the foreign operation, expressed in its functional currency and retranslated at the closing rate at each reporting date.

Goodwill on a foreign subsidiary is therefore not fixed in the group's presentation currency. It is fixed in the subsidiary's currency and changes at every reporting date, with the movement recognised in other comprehensive income.

The two ways of measuring the non-controlling interest

IFRS 3 paragraph 19 gives an acquirer a choice, made separately for each business combination, and it determines how much goodwill exists to be retranslated:

• Fair value, sometimes called the full goodwill method. The non-controlling interest is measured at its acquisition-date fair value, and the goodwill recognised includes an amount attributable to it.
• Proportionate share of the acquiree's identifiable net assets. No goodwill is attributed to the non-controlling interest, so the goodwill recognised is the parent's alone.

The choice matters here because goodwill is retranslated at every reporting date. Where the non-controlling interest holds part of the goodwill, it takes the matching share of the translation difference on it; where it does not, the whole of that difference belongs to the parent. Since only the parent's share is ever reclassified to profit or loss, the measurement basis chosen on day one sets how much of the goodwill difference can ever be recycled.

The example measures the non-controlling interest at fair value. The calculation is done in dollars first:

The identifiable net assets of $2,900 are S's own equity of $2,500 plus the $500 fair value adjustment on land less $100 of deferred tax. Of the $500 goodwill, $400 is the parent's — what it paid, less its 80% share of those net assets — and the remaining $100 belongs to the non-controlling interest. Retranslation is mechanical:

Measuring the non-controlling interest the other way changes both the goodwill and the reserve it generates:

The parent's goodwill is $400 either way, because it is what the parent paid less its share of the identifiable net assets. What differs is whether the extra $100 exists at all, and with it the $10 a year of translation difference that follows the non-controlling interest.

Attributing the reserve to non-controlling interests

IAS 21 paragraph 41 is explicit: where a foreign operation is consolidated but not wholly owned, the accumulated differences attributable to non-controlling interests are allocated to, and recognised as part of, non-controlling interests.

Only the parent's share is reclassified on disposal or available for transfer on a partial disposal. In the statement of comprehensive income the full difference is one item of other comprehensive income that may be reclassified subsequently, attributed between owners of the parent and non-controlling interests; in the statement of changes in equity the reserve column shows only the parent's share.

Example: Two-Year Analysis of Equity

The analysis of equity is the most efficient route to consolidation, producing the translation difference, the parent's share and the non-controlling interest balance in one place. Each row is translated at its own rate, the closing net assets at the closing rate, and the difference is the reserve.

S earned $500 in 20X4 and $600 in 20X5, and paid a dividend of $250 on 30 September 20X5.

Both balancing figures decompose exactly. For 20X4: 2,900 x 0.10 on opening net assets, plus 500 x 0.05 on profit, gives 315. For 20X5: 3,400 x 0.10, plus 600 x 0.05, less 250 x 0.04 on the dividend, gives 360.

The non-controlling interest balance

The non-controlling interest was measured at fair value, so it carries its share of net assets plus its share of goodwill.

The closing balance proves directly: 20% of net assets of 3,375 is 675, plus the non-controlling interest's $100 of goodwill at 0.90, being 90.

Other comprehensive income for 20X5 shows one line, "exchange differences on translating foreign operations", of 410 — the 360 on net assets plus the 50 on goodwill — attributed 328 to the owners of the parent and 82 to the non-controlling interests. The cumulative reserve at 31 December 20X5 is 775: 620 in the parent's reserve column and 155 inside the non-controlling interest balance.

Monetary Items Forming Part of the Net Investment

Groups rarely fund a foreign subsidiary with equity alone. Where a long-term intragroup loan is outstanding, IAS 21 paragraph 15 treats it as part of the net investment in the foreign operation if settlement is neither planned nor likely in the foreseeable future. Trade receivables and payables do not qualify.

Paragraph 32 gives the consequence: the difference is recognised in profit or loss in the separate financial statements of whichever entity carries the exposure, but in other comprehensive income on consolidation, with any tax on it. The holder need not be the parent — paragraph 15A extends the treatment to any subsidiary — and it applies irrespective of the currency the item is denominated in.

The currency the loan is denominated in decides where the difference arises, and so whether the non-controlling interest shares in it. Assume P advances a long-term loan to S on 1 January 20X4 of £560, equivalent to $800 at the acquisition-date rate.

The economics are identical in both columns: the dollar strengthened and the net investment is worth more in sterling. The amounts differ only because one route runs the difference through a closing rate on the parent's balance and the other through the average rate applied to the subsidiary's profit.

The loan balance itself is then eliminated in the normal way; both sides are stated at the closing rate, so they offset exactly. Differences recognised in earlier periods sit inside the parent's opening retained earnings and are moved to the opening balance of the translation reserve, net of tax, each year the loan is outstanding.

Intragroup Transactions and Unrealised Profit

Intragroup balances and transactions are eliminated in full under IFRS 10. Translating one side of them into a different currency does not change that; it changes the rate at which each elimination is measured.

Because the sale is eliminated at the average rate and the unrealised profit at the closing rate, the two do not offset to nil in the presentation currency. The residual is an exchange difference on translating the foreign operation and belongs in the translation reserve, not in profit or loss.

The direction of the sale determines who bears the elimination. An upstream sale reduces the subsidiary's profit, so the non-controlling interest takes its share; a downstream sale reduces the parent's profit and leaves the non-controlling interest untouched. Translation does not alter this.

Where the arrangement is a lease, the elimination has its own mechanics, set out in our guide to intercompany leases under IFRS 16. A lease held by the subsidiary in a currency other than its own functional currency is different again: the liability is a monetary item in its own accounts and generates differences before any translation, as foreign currency leases under IFRS 16 explains.

Disposals, Partial Disposals and Recycling

The translation reserve accumulates for as long as the operation is held, and is released only when the group's interest in it changes. What happens then turns on a single question: does the group still control the subsidiary afterwards?

If control is lost — the subsidiary is sold outright, or the retained interest is no longer a subsidiary — the parent's accumulated reserve is reclassified out of equity and into profit or loss, where it forms part of the gain or loss on disposal. That reclassification is what recycling means, and it happens in full. Reducing an 80% holding to 10% releases the whole of the parent's reserve, because the release follows the loss of control rather than the proportion sold. The same treatment applies when significant influence over an associate is lost, for the share previously equity accounted.

If control is retained — 80% down to 60%, say — IFRS 10 treats the sale as a transaction between owners rather than a disposal. No gain or loss arises, so nothing is recycled. Instead the part of the parent's reserve that relates to the interest given up moves across to non-controlling interests, entirely within equity.

Partial disposal, step by step

P sells a quarter of its holding on 31 December 20X5, taking its interest in S from 80% to 60%. Control is retained, so this is the second column above.

1. Identify the parent's accumulated reserve. It is 620: 540 from translating S's net assets and 80 from translating goodwill.
2. Work out the proportion that passes across. P gives up 20 of the 80 percentage points it held, so a quarter of everything attributable to it transfers to the non-controlling interests.
3. Transfer it. A quarter of 540 is 135, and a quarter of 80 is 20, so 155 moves from the parent's translation reserve to non-controlling interests — alongside the proportionate share of every other reserve making the same journey.
4. Recognise the change in ownership. The consideration received, less the total increase in the non-controlling interest, is recognised directly in equity.
5. Realise the amount transferred. The 155 no longer relates to an interest the parent holds, so it is transferred out of the translation reserve into retained earnings on the face of the statement of changes in equity.

Nothing is recognised in profit or loss or in other comprehensive income at any stage.

Step 3 can be checked against the other side of the transaction. The non-controlling interests already held 155 of accumulated reserve on their 20%; doubling their interest to 40% doubles it to 310. Had P sold the whole 80% instead, the full 620 would have been reclassified to profit or loss as part of the gain on disposal.

Foreign Associates and Joint Ventures

A foreign associate or joint venture is also a foreign operation and the same principles apply, except that no separate goodwill asset is recognised: the goodwill is embedded in the carrying amount of the investment. The most direct method is to apply the equity method in the investee's functional currency and translate the resulting carrying amount.

P acquired 30% of A on 1 January 20X4 for £630, equivalent to $900, when A's equity was $2,800. A earned $200 in 20X4.

The difference decomposes as before: $900 of opening net investment multiplied by the 0.10 movement in the rate gives 90, and the $60 share of profit gives a further 3. Because the $900 cost already contains $60 of goodwill, this single calculation captures the difference on the goodwill too. It is presented within the investor's share of the other comprehensive income of the associate, and reclassified in full on any loss of significant influence.

Presentation and Disclosure

IAS 21 paragraphs 51 to 57 require disclosure of exchange differences recognised in profit or loss, excluding those on financial instruments at fair value through profit or loss; the net differences recognised in other comprehensive income, with a reconciliation of the translation reserve at the beginning and end of the period; and, where the presentation currency differs from the functional currency, that fact, the functional currency and the reason. A change in functional currency of the reporting entity or of a significant foreign operation is disclosed with its reason.

Two requirements outside IAS 21 apply alongside these. Where determining the functional currency of a significant operation required judgement, IAS 1 requires that judgement to be disclosed. Where a subsidiary has material non-controlling interests, IFRS 12 requires summarised financial information about it in the group's presentation currency.

In the consolidated statement of cash flows, IAS 7 applies its own rules: a foreign subsidiary's cash flows are translated at the rates on the dates of those flows (paragraph 26, weighted average permitted by paragraph 27), unrealised exchange gains and losses are not cash flows (paragraph 25), and the effect of rate changes on cash and cash equivalents is a separate reconciling line between opening and closing cash (paragraph 28). Our guides to consolidated cash flow statements and foreign exchange in the cash flow statement work through the reconciliations that strip retranslation out of each consolidated balance.

Quick Reference Summary

Conclusion

Consolidating a foreign subsidiary under IFRS separates cleanly into translation and consolidation. Translation follows three rules — assets and liabilities at the closing rate, income and expenses at transaction or average rates, and the resulting difference to other comprehensive income — and the reserve it creates can always be proved against its components: opening net assets, profit, dividends, goodwill and fair value adjustments.

The judgement sits at the edges rather than in the mechanics. The functional currency decides whether a currency movement reaches profit or loss at all; the designation of intragroup loans decides whether their differences are held in equity; and the measurement basis chosen for the non-controlling interest decides how much of the goodwill difference the parent can ever recycle. Once those are settled, the translation is arithmetic.
