Currency translation in consolidation
When a group translates a foreign company, the balance sheet is translated at the closing rate, profit and loss at the average rate and equity at historical rates. Because the rates differ, the translated balance sheet does not balance by itself. The difference is the translation reserve, held in equity.
A group that reports in one currency still has companies that keep their books in others. Before their figures can be added to the group's, each foreign company is translated. The method is simple to state and easy to get wrong: different kinds of figure use different rates.
Three rates for three kinds of figure
| Figure | Rate | Reason |
|---|---|---|
| Assets and liabilities | Closing rate: the rate on the last day of the period | They are worth what they could be exchanged for at the balance sheet date. |
| Revenue and costs | Average rate for the period | They arise evenly through the month, so an average stands in for each day's rate. |
| Share capital and earlier reserves | Historical rate: the rate when the capital was issued or the profit was earned | They are a record of what was put in or earned at the time, and do not move with today's rate. |
Check the direction of the rate
A rate is quoted one of two ways, and using it the wrong way round is the commonest translation error. The Zenvara group uses these September 2026 average rates:
- Rupees: 83.50 rupees to the dollar. Divide: 1,53,807 thousand rupees ÷ 83.50 = 1,842 thousand dollars.
- Pounds: 1.27 dollars to the pound. Multiply: 762 thousand pounds × 1.27 = 967.7, shown as 968.
- Dirhams: 3.6725 dirhams to the dollar. Divide: 2,732 ÷ 3.6725 = 743.9, shown as 744.
- Singapore dollars: 1.34 to the dollar. Divide: 686 ÷ 1.34 = 511.9, shown as 512.
A quick test before using any rate: the translated number should be roughly what you expect. A pound is worth more than a dollar, so pounds become more dollars. A rupee is worth far less, so rupees become far fewer dollars.
Why the translation reserve appears
Assets and liabilities move with the closing rate. Share capital sits at the rate on the day it was issued, and earned profits sit at the rates of the periods in which they were earned. When the exchange rate moves, these rates stop agreeing, and the translated balance sheet is out of balance by the difference.
That difference is the translation reserve. It is a balancing figure in equity. It is not profit or loss, and it is not a cash movement. It records what holding a foreign company has been worth, in the group's currency, as the exchange rate moved.
A worked example: Zenvara UK Ltd, September 2026
Zenvara UK Ltd keeps its books in pounds. At the end of September, the closing rate is 1.25 dollars to the pound. The share capital was issued at 1.31. Retained earnings brought forward of £577 thousand are carried at 1.29, and the September profit of £123 thousand is translated at the September average of 1.27. Amounts are in thousands.
| Item | Pounds | Rate | Dollars |
|---|---|---|---|
| Assets | 2,000 | 1.25 closing | 2,500 |
| Liabilities | 800 | 1.25 closing | 1,000 |
| Net assets | 1,200 | 1.25 closing | 1,500 |
| Share capital | 500 | 1.31 historical | 655 |
| Retained earnings, opening | 577 | 1.29 historical | 744 |
| September profit | 123 | 1.27 average | 156 |
| Retained earnings, total | 700 | 901 | |
| Translation reserve | (56) | ||
| Equity | 1,200 | 1,500 |
Equity adds up: 655 + 901 − 56 = 1,500, the same as the net assets of 1,500. The 901 is 744.33 plus 156.21, which is 900.54 before rounding, so the two rounded lines show 744 and 156 and the total shows 901. The reserve is (55.54) before rounding and shown as (56).
Why is it negative? The pound has weakened. The share capital and the earlier profits are carried at 1.31, 1.29 and 1.27, all above today's 1.25, so on those rates the equity would be worth 1,555.54. The net assets are worth 1,500 at the closing rate. The reserve of (55.54) is the difference.
The September profit of 156 is also the figure that goes into the group profit and loss, as the UK line in the consolidation example.

Pounds in thousands into US dollars in thousands, rates in dollars per pound. Only the two rates change. Assets 2000, liabilities 800, share capital 500 at 1.31, opening retained earnings 744.33 dollars, profit 123.
| Line | Rate | Dollars |
|---|---|---|
| Assets | Closing | 2,500.00 |
| Liabilities | Closing | 1,000.00 |
| Share capital | 1.31 | 655.00 |
| Retained earnings, opening | Fixed | 744.33 |
| Profit for the period | Average | 156.21 |
| Translation reserve | Balancing | (55.54) |
| Total equity | 1,500.00 | |
| Liabilities plus equity | 2,500.00 |
Balanced: assets 2,500.00 equal liabilities plus equity 2,500.00.

Quarters and years
Profit and loss for a quarter or a year is the sum of the months, each translated at its own average rate. The year to date is therefore not the year's profit in pounds multiplied by one rate. This is why the average rate has to be kept for every month, and why comparing a year to date with the same period last year needs both years' monthly rates.
Common mistakes
- Using the wrong rate for the figure. The average rate on the balance sheet, or the closing rate on profit and loss, misstates both the statements and the reserve.
- Using the rate the wrong way round. Multiplying rupees by 83.50 instead of dividing gives a number about seven thousand times too large.
- Forgetting the reserve brought forward. The translation reserve is cumulative. Each month adds its own movement to the balance of the month before.
- Translating the same item at two rates. An intercompany balance translated at different rates in the two companies will not match when the group compares them.
Practical points
- A group reports in one currency. Companies already in that currency need no translation.
- Keep the rate used for each currency and each month, so a figure can be reproduced later.
- Compare each rate with the previous month. A jump that is not in the market is usually a typing or direction error.
- Translate the whole company, not selected lines, so that the balance sheet and the reserve stay consistent.
- Intercompany balances between companies in different currencies need the same rate on both sides, or a difference appears. See intercompany eliminations, explained.
