11Sterling equivalents: basic ruleU.K.
(1)Subsection (2) applies if, for the purposes of calculating the profits or losses of a company arising in an accounting period, section 7(2), 8(2) or 9(2) requires a profit or loss to be translated into its sterling equivalent.
(2)The translation must be made by reference to—
(a)the average exchange rate for the accounting period, or
(b)the rate mentioned in subsection (3).
(3)That rate is—
(a)if the amount to be translated relates to a single transaction, an appropriate spot rate of exchange for the transaction, or
(b)if the amount to be translated relates to more than one transaction, a rate of exchange derived on a just and reasonable basis from appropriate spot rates of exchange for those transactions.
(4)Subsection (2) is subject to sections 12 and 13 (special rules where the translation is for the purpose of calculating carried-forward or carried-back amounts).
