Paragraph 8
For each chargeable period of a foreign field beginning with that in which a participator in that field has chargeable receipts, there shall be determined, subject to the following provisions of this Schedule but otherwise in accordance with section 2 of the principal Act, what is the assessable profit or allowable loss accruing to the participator from the foreign field on the basis that—
the positive amounts for the purposes of section 2 of the principal Act consist of any chargeable receipts of his attributable to that field for that period; and
the negative amounts for those purposes are any amounts referred to in paragraphs (b), (c) and (f) of subsection (9) of that section.
For the purpose of the determination referred to in sub-paragraph (1) above, the provisions of Part I of the principal Act and sections 3 and 4 of and Part II of Schedule 1 to this Act shall have effect—
on the relevant assumptions; and
on the further assumption that any reference in those provisions to an oil field or a participator applies only to a foreign field or, as the case may be, a participator in a foreign field.
Without prejudice to sub-paragraph (2) above, in computing the assessable profit or allowable loss accruing to a participator in a foreign field, section 9 of and Schedule 3 to this Act shall apply—
on the relevant assumptions; and
on the further assumption that any chargeable receipts of his, other than those falling within subsection (1)(c) of the principal section, are tariff receipts,
In any case where, apart from this sub-paragraph, the whole or any part of any consideration which constitutes a chargeable receipt of a participator in a foreign field would also fall to be treated, by virtue of paragraph 2 or paragraph 11 of Schedule 2 to this Act, as a tariff or disposal receipt of a participator in a United Kingdom field, it shall not be so treated.
In any case, where, apart from this sub-paragraph, the whole or any part of any consideration which constitutes a tariff or disposal receipt of a participator in a United Kingdom field would also fall to be treated, by virtue of paragraph 2 or paragraph 11 of Schedule 2 to this Act, as applied by paragraph 5(1) above, as a chargeable receipt of a participator in a foreign field, it shall not be so treated.
