Multi-currency consolidation for groups with foreign subsidiaries

To consolidate a foreign subsidiary, translate its books into the group's currency: closing rate for the balance sheet, average rate for profit and loss, historical rates for equity. The leftover difference is the translation reserve. Finconsol applies the right rate to each part, suggests the rates and works out the reserve.

Translate into the group currency

Zenvara UK Ltd keeps its books in pounds. The group reports in US dollars, in thousands.

The balance sheet of Zenvara UK Ltd is translated from pounds to dollars: assets and liabilities at the closing rate of 1.25, share capital at the historical rate of 1.31, and retained earnings at the opening and average rates. The translation reserve of minus 56 is the difference that keeps the balance sheet in balance, and total equity of 1,500 equals net assets.

Rupees, pounds and dirhams do not add up

A group with an Indian parent, a UK company, a Dubai company and a Singapore company has four sets of books in four currencies. The board wants one balance sheet and one profit and loss, in one currency.

Converting every line at one rate looks quick, and it leaves the balance sheet out of balance. The harder questions come next: which rate for which line, and where the leftover difference goes.

  • The balance sheet does not balance. Assets, profit and equity are translated at different rates, so the totals stop agreeing.
  • Rates are chased every month. Someone looks up a closing rate, an average rate and the old rates for equity, for each currency.
  • Growth looks wrong. A stronger dollar makes a growing subsidiary look flat, and nobody can say how much was rates.
  • One typo carries on. A wrong rate in a cell reaches the board pack unchecked.

Which rate applies to which part

Each part of a subsidiary's statements has its own rate. The group's accounts are only right when every part uses the rate that belongs to it.

Why the reserve exists

Take Zenvara UK Ltd, which keeps its books in pounds. Its net assets of £1,200 thousand are translated at the closing rate of 1.25 into 1,500 thousand dollars. Its equity, built from share capital at 1.31, opening profits at 1.29 and the September profit at an average of 1.27, comes to 1,556. The balance sheet is 56 out. That 56 is the translation reserve, shown as (56), and it brings equity back to 1,500.

Where spreadsheets break

  • Rates are typed in by hand and pasted over last month's.
  • The historical rates for equity are kept in someone's notes, or lost.
  • The reserve is worked out as a plug at the end, so nothing proves it is right.
  • Last year's rates are not kept, so growth at constant currency is a separate exercise.

How Finconsol translates a group

  1. Rates are suggested for you

    For each currency and period, Finconsol suggests closing and average rates from published reference rates. You can type over any of them, and sanity checks flag a rate that looks out of line.

  2. Each part gets its own rate

    Balance sheet lines use the closing rate, profit and loss lines use the average rate and equity uses historical rates. You do not choose rates line by line.

  3. The reserve is calculated

    The translation reserve is worked out for every company, so each balance sheet balances before it is added to the group.

  4. The group adds up in one currency

    The group reports in one currency. All companies are translated into it, and every statement, dashboard and board pack shows the same currency.

Growth at constant currency

A rate move can hide real growth or invent it. The board summary shows growth at constant currency next to reported growth, so the board can see how much of the change came from the business and how much from exchange rates.

Companies in any system

Zoho Books companies are read directly. Companies on Xero or QuickBooks come in by trial balance upload today, with a direct connection coming soon, and any other system that exports a trial balance works the same way. All of them are translated by the same rules.

What you get

  • Group statements in one currency: balance sheet, profit and loss, cash flow and fund flow, each with its own balance check.
  • A translation reserve for every company and every period, calculated and shown on the balance sheet.
  • A consolidation worksheet with a column per company in the group currency, tied to the published statements.
  • Rates you can see and change, with the suggested rate beside the one in use.
  • Growth at constant currency on the board summary and in board packs.

Good to know

  • The group has one reporting currency. Each company keeps its own currency in its books and is translated into the group's.
  • Suggested rates are a starting point. If your policy or your auditor uses another source, type your rate over the suggestion.
  • Finconsol only reads from the companies' books. Rates and translation live in Finconsol, so nothing changes in a company's books.

Questions

How do you consolidate a foreign subsidiary?
You translate the subsidiary's books from its own currency into the group's reporting currency, then combine them with the other companies. Assets and liabilities use the closing rate, profit and loss uses the average rate, and equity uses historical rates. Whatever difference is left goes to the translation reserve.
What is the difference between the closing rate and the average rate?
The closing rate is the rate on the last day of the period, and it values what the company owns and owes on that day. The average rate is the typical rate across the period, and it values what the company earned and spent while the period ran. Using the average for profit and loss avoids giving the last day of the month too much weight.
What is the translation reserve?
It is the balancing figure that appears because assets and liabilities, profit and loss and equity are translated at different rates. Without it, the group balance sheet would be out of balance by exactly that amount. Finconsol calculates it for every company and every period, so the group balance sheet always balances.
Where do the exchange rates come from?
Finconsol suggests rates from published reference rates, so nobody has to look them up each month. Every suggested rate can be typed over, and sanity checks flag a rate that looks wrong before it reaches the group accounts.
Can I use my own rates instead of the suggested ones?
Yes. If your bank, auditor or policy uses a different source, type your rate over the suggestion for that currency and period. The translated figures and the translation reserve follow the rate you enter.
Can the group report in more than one currency?
No. Each company keeps its books in its own currency, and the group reports in one currency. Every group statement, dashboard and board pack is shown in that currency, so the numbers can be added and compared.
What is growth at constant currency?
It is growth measured as if exchange rates had not moved. When a subsidiary is translated at a different rate from last year, reported growth mixes real growth with the rate effect. Constant currency growth on the board summary separates the two, so the board sees how the business grew.
Can companies on Xero or QuickBooks be translated too?
Yes. Companies on Xero or QuickBooks join today by trial balance upload, with a direct connection coming soon. Once a company is in the group, it is translated in the same way as a Zoho Books company.
