(1)This section only applies in relation to a member of a multinational group where its accounting currency and its tax currency are different.
(2)Where—
(a)the member has a gain or a loss as a result of fluctuations in the exchange rate between its accounting currency and its tax currency, and
(b)the gain or loss is reflected differently in its taxable income and in the determination of its underlying profits (including where it is not reflected at all in one of those),
the member’s underlying profits are to be adjusted so that the gain or loss is reflected in those profits on the same basis it is reflected in its taxable income.
(3)Where—
(a)the member has a gain or a loss as a result of fluctuations in the exchange rate between its accounting currency and a third currency,
(b)the gain or loss is reflected in its underlying profits, and
(c)the gain or loss is not reflected, or is reflected to a different extent, in its taxable income,
the member’s underlying profits are to be adjusted to exclude that gain or loss.
(4)Where—
(a)the member has a gain or a loss as a result of fluctuations in the exchange rate between its tax currency and a third currency, and
(b)the income or loss is not reflected, or is reflected to a different extent, in its underlying profits,
the member’s underlying profits are to be adjusted so that the gain or loss is fully reflected in those profits (whether or not it is reflected in its taxable income).
