(2) For each oil field the tax shall, in the case of each participator, be charged at the rate of 45 per cent. on the assessable profit accruing to him in any chargeable period from that field, as reduced under section 7 of this Act by any allowable losses and under section 8 of this Act by reference to his share, if any, of the oil allowance for that period, subject however to the limit imposed in his case by section 9 of this Act.

(3) In relation to any oil field—

(a ) the first chargeable period is the period ending at the end of the critical half year (including an unlimited time prior to the beginning of that half year); and

(b ) each subsequent half year is a chargeable period.

(4) In this section—

‘the critical half year’, in relation to an oil field, means the first half year ending after 12th November 1974 at the end of which the total amount of oil ever won and saved from the field exceeds 1,000 long tons (counting 40,000 cubic feet of gas at a temperature of 15 degrees centigrade and pressure of one atmosphere as equivalent to one long ton);

‘half year’ means a period of six months ending at the end of June or December.

(5) Schedule 1 to this Act shall have effect with respect to the determination of oil fields, and Schedule 2 to this Act shall have effect with respect to the management and collection of the tax; and this Part of this Act shall have effect subject to the further provisions in Schedule 3 to this Act and, in connection with certain gas sold to the British Gas Corporation, to section 10 of this Act.

(1) For the purposes of the tax the assessable profit or allowable loss accruing to a participator in any chargeable period from an oil field shall be computed in accordance with the following provisions of this section.

(2) The assessable profit or allowable loss so accruing in the period is the difference (if any) between the sum of the positive amounts for the period and the sum of the negative amounts for the period; and that difference (if any) is an assessable profit if the sum of the positive amounts is greater than the sum of the negative amounts, and is otherwise an allowable loss.

(3) For the period—

(a ) the positive amounts for the purposes of this section are the following (as defined in this section), namely the gross profit (if any) accruing to the participator in the period, his licence credit (if any) for the period, and any amount to be credited to him for the period in respect of expenditure; and

(i) not disposed of and not relevantly appropriated; or

(ii) disposed of but not delivered,

and the difference (if any) is a gross profit if the said aggregate is greater than one-half of the said market value, and is otherwise a gross loss.

(5) The amounts referred to in subsection (4)(a ) above are—

(a ) the price received or receivable for so much of any oil won from the field and disposed of by him crude in sales at arm's length as was delivered by him in the period (excluding oil delivered before 13th November 1974);

(b ) the aggregate market value, ascertained in accordance with Schedule 3 to this Act, of so much of any oil so won and disposed of by him crude otherwise than in sales at arm's length as was delivered by him in the period (excluding oil delivered before 13th November 1974);

(c ) the aggregate market value, ascertained in accordance with Schedule 3 to this Act, of so much of any oil so won as was relevantly appropriated by him in the period without being disposed of (excluding oil so appropriated before 13th November 1974); and

(d ) one-half of the market value, at the end of the period, of so much of his share of oil so won as he had then either—

(i) not disposed of and not relevantly appropriated; or

(a ) the sum of the amounts mentioned in subsection (9) below; and

(b ) subject to subsection (10) below, any amount taken into account under paragraph (a ) of the said subsection (9) in computing the assessable profit or allowable loss accruing to the participator in the last but one preceding chargeable period;
