Accounts drawn up in a foreign currency: FA 2009: carrying back non-sterling losses

Carrying back of non-sterling losses

This guidance applies to accounting periods beginning on or after 29 December 2007

The legislation dealing with carrying back losses that have been computed in a currency other than sterling is at FA93/S92DA. A translation made under these rules must be made in accordance with one of three rules.

Rule 1

This is the most common circumstance. It applies where the operating currency in the accounting period when the loss arose is the same as the operating currency in the earlier accounting period when the loss is offset.

Where Rule 1 applies, the loss would be translated into sterling at the same exchange rate as the rate used to translate the profits in the earlier period.

CFM64370 has an example of Rule 1 in operation.

Rules 2 and 3

Rules 2 and 3 apply where there are non-sterling losses carried back and the operating currency of the company has changed.

CFM64420 has further details on the rules that apply where there is a change of operating currency.
