(3) Where—

(a) a person disposes otherwise than in a sale at arm’s length (as defined in paragraph 1 of Schedule 3 to the 1975 Act) of oil acquired by him in the course of oil extraction activities carried on by him or by virtue of oil rights held by him, and

(b) subsection (1) above does not apply in relation to the disposal,

then, for all purposes of income tax and for the purposes of the charge of corporation tax on income, the disposal of the oil and its acquisition by the person to whom it was disposed of shall be treated as having been for a consideration equal to the market value of the oil in the calendar month in which the disposal was made.

(4) If a person appropriates oil acquired by him in the course of oil extraction activities carried on by him or by virtue of oil rights held by him and the appropriation is to refining or to any use except for production purposes of an oil field, within the meaning of Part I of the 1975 Act, then, unless subsection (2) above applies, for all purposes of income tax and for the purposes of the charge of corporation tax on income—

(a) he shall be treated as having, at the time of the appropriation, sold and bought the oil as mentioned in subsection (2)(a)(i) and (ii) above; and

(b) that sale and purchase shall be deemed to have been at a price equal to the market value of the oil in the calendar month in which it was appropriated.

(5) For the purposes of subsections (3) and (4) above—

(a) “calendar month” means a month of the calendar year; and

(b) paragraph 2 of Schedule 3 to the 1975 Act shall apply as it applies for the purposes of Part I of that Act, but with the following modifications, that is to say—

(2) Interest paid by a company shall not be allowable under section 338 as a deduction against the company’s ring fence profits except—

(a) to the extent that it was payable in respect of money borrowed by the company which is shown to have been used to meet expenditure incurred by the company in carrying on oil extraction activities or in acquiring oil rights otherwise than from a connected person or to have been appropriated to meeting expenditure to be so incurred by the company; and

(b) in the case of interest paid by the company to a company associated with it, to the extent that (subject always to paragraph (a) above) the rate at which it was payable did not exceed what, having regard to all the terms on which the money was borrowed and the standing of the borrower, was a reasonable commercial rate.

Section 839 shall apply for the purposes of this subsection.

(3) Where a company pays to a company associated with it a charge on income not consisting of a payment of interest, the charge shall not be allowable to any extent under section 338 against the first-mentioned company’s ring fence profits.

(a) such of the charges on income which are paid by a company and allowable under section 338 as, by virtue of subsections (2) and (3) above, are not allowable against the company’s ring fence profits exceed the remaining part of its profits (the company’s (“non-oil profits”), and

(b) the amount of that excess is greater than the amount (if any) by which the total of the charges on income which are allowable to the company under that section exceeds the total of the company’s profits,

then, for the purpose of enabling the company to surrender the excess referred to in paragraph (a) above by way of group relief, section 403(7) shall have effect as if in that subsection—

(i) the reference to the amount paid by the surrendering company by way of charges on income were a reference to so much of that amount as is allowable only against the company’s non-oil profits; and

(ii) the reference to the surrendering company’s profits were a reference to its non-oil profits alone.

495 Regional development grants

(6) If there is a reduction in the allowance, then, for the purpose of determining the liability to income tax or corporation tax of the person concerned, he shall be treated as having received in the adjustment period, as income of the trade in connection with which the expenditure referred to in subsection (3)(a) above was incurred, a sum equal to the amount of the reduction in the allowance.

496 Tariff receipts

(1) Any sum which—

(a) constitutes a tariff receipt of a person who is a participator in an oil field, and

(b) constitutes consideration in the nature of income rather than capital, and

(c) would not, apart from this subsection, be treated for the purposes of this Chapter as a receipt of the separate trade referred to in section 492(1),

shall be so treated for those purposes.

(2) To the extent that they would not otherwise be so treated, the activities of a participator in an oil field or a person connected with him in making available an asset in a way which gives rise to tariff receipts of the participator shall be treated for the purposes of this Chapter as oil extraction activities.

(3) In determining for the purposes of subsection (1) above whether any sum constitutes a tariff receipt of a person who is a participator, no account shall be taken of any sum which—

(a) is in fact received or receivable by a person connected with the participator, and

(2) Where advance corporation tax is paid by a company (“the distributing company”) in respect of any distribution made by it to a company associated with it and resident in the United Kingdom or, where subsection (3) below applies, in respect of any distribution consisting of a dividend on a redeemable preference share—

(a) that advance corporation tax shall not be set against the distributing company’s liability to corporation tax on any ring fence income of the distributing company; and

(b) if the benefit of any amount of that advance corporation tax is surrendered under section 240 to a subsidiary of the distributing company, the corresponding amount of advance corporation tax which under that section the subsidiary is treated for the purposes of section 239 as having paid shall not be set against the subsidiary’s liability to corporation tax on any ring fence income of the subsidiary.

(3) Subject to subsection (4) below, this subsection applies in relation to the payment of a dividend on redeemable preference shares if the dividend is paid on or after 17th March 1987 and—

(a) at the time the shares are issued, or

(a) were used to meet expenditure incurred by the company issuing them in carrying on oil extraction activities or in acquiring oil rights otherwise than from a connected person; or

(b) were appropriated to meeting expenditure to be so incurred by that company;

and section 839 applies for the purposes of this subsection.

(5) Where in the case of any accounting period of a company there is an amount of advance corporation tax which because of subsection (2) above is not available to be set against the company’s liability to corporation tax for that period on ring fence income of the company, section 239(2) shall as regards that period have effect as if the reference to the company’s profits charged to corporation tax for that period were a reference to the company’s profits so charged exclusive of any ring fence income.

(6) For the purposes of subsections (2) to (4) above, shares in a company are redeemable preference shares either if they are so described in the terms of their issue or if, however they are described, they fulfil the condition in paragraph (a) below and either or both of the conditions in paragraphs (b) and (c) below—

(a) that, as against other shares in the company, they carry a preferential entitlement to a dividend or to any assets in a winding up or both;

498 Limited right to carry back surrendered ACT

(1) In any case where,—

(a) on a date not earlier than 17th March 1987, a company which is the surrendering company for the purposes of section 240 paid a dividend; and

(b) at no time in the accounting period of the surrendering company in which that dividend was paid was the surrendering company under the control of a company resident in the United Kingdom (construing “control” in accordance with section 416); and

(c) under section 240(1) the benefit of the advance corporation tax paid in respect of that dividend was surrendered to a subsidiary of the surrendering company; and

(d) that advance corporation tax is not such that the restriction in paragraph (a) or paragraph (b) of section 497(2) applies with respect to it; and

(e) in one or more of the accounting periods of the subsidiary beginning in the six years preceding the accounting period in which falls the date referred to in paragraph (a) above, the subsidiary has a liability to corporation tax in respect of profits which consist of or include ring fence profits,

sections 239 and 240 shall have effect subject to subsections (3) to (7) below.

(2) Where the conditions in subsection (1) above are fulfilled, the subsidiary to which the benefit of the advance corporation tax is surrendered is in the following provisions of this section referred to as a “qualifying subsidiary”; and in those provisions—

(a) “the surrendering company” has the same meaning as in section 240;

(b) “surrendered advance corporation tax” means advance corporation tax which, by virtue of section 240(2), a qualifying subsidiary is treated as having paid in respect of a distribution made on a particular date; and

(c) “the principal accounting period” means the accounting period of the qualifying subsidiary in which that date falls.

(3) So much of section 240(4) as would prevent surrendered advance corporation tax being set against a qualifying subsidiary’s liability to corporation tax under section 239(3) shall not apply, but section 239(3) shall instead have effect subject to the following provisions of this section.

(4) Surrendered advance corporation tax may not under section 239(3) be set against a qualifying subsidiary’s liability to corporation tax for an accounting period earlier than the principal accounting period unless throughout—

(a) that period,

(b) the principal accounting period, and

(c) any intervening accounting period,

the qualifying subsidiary was carrying on activities which, under and for the purposes specified in section 492, constitute a separate trade.

(5) Subject to subsection (6) below, for each accounting period of the surrendering company in which is paid a dividend the advance corporation tax on which gives rise, under section 240, to surrendered advance corporation tax, the total amount of that surrendered advance corporation tax in respect of which claims may be made under section 239(3) (whether by one qualifying subsidiary of the surrendering company or by two or more taken together) shall not exceed whichever of the following limits is appropriate to the accounting period of the surrendering company—

(a) for periods ending on or after 17th March 1987 and before 1st April 1989, £10 million;

(b) for periods ending on or after 1st April 1989 and before 1st April 1991, £15 million;

(c) for later periods, £20 million.

(6) In any case where an accounting period of the surrendering company is less than 12 months, the amount which is appropriate to it under subsection (5)(a) to (c) above shall be proportionately reduced.

(7) The amount of surrendered advance corporation tax of the principal accounting period which, on a claim under section 239(3), may be treated as if it were advance corporation tax paid in respect of distributions made by the qualifying subsidiary concerned in any earlier accounting period shall not exceed the amount of advance corporation tax that would have been payable in respect of a distribution made at the end of that earlier period of an amount which, together with the advance corporation tax so payable in respect of it, would equal the qualifying subsidiary’s ring fence profits of that period.

(8) In determining the amount (if any) of advance corporation tax which may be repayable—

(a) under section 17(3) of the 1975 Act, or

(b) under section 127(5) of the [1981 c. 35.] Finance Act 1981,

any advance corporation tax in respect of a distribution actually made on or after 17th March 1987 shall be left out of account.

499 Surrender of ACT where oil extraction company etc. owned by a consortium

(1) In any case where—

(a) a company (in this section referred to as (“the consortium company”) is owned by a consortium consisting of two members only, each of which owns 50 per cent. of the issued share capital of the company; and

(b) the consortium company carries on a trade consisting of or including activities falling within section 492(1)(a) to (c); and

(c) all of the issued share capital of the consortium company is of the same class and carries the same rights as to voting, dividends and distribution of assets on a winding up,

section 240 shall have effect, subject to the following provisions of this section, as if the company were a subsidiary of each member of the consortium.

(2) This section has effect with respect to advance corporation tax paid by either member of the consortium in respect of a dividend paid by it on or after 17th March 1987; and, in relation to a surrender under section 240 of the benefit of the advance corporation tax paid in respect of such a dividend—

(a) “surrendered advance corporation tax” means advance corporation tax which, by virtue of section 240(2), the consortium company is treated as having paid; and

(b) “the notional distribution date” means the date of the distribution in respect of which the surrendered advance corporation tax is treated as paid.

(3) No surrender under section 240 of the benefit of advance corporation tax may be made by virtue of this section—

(a) unless the conditions in paragraphs (a) to (c) of subsection (1) above are fulfilled throughout that accounting period of the consortium company in which falls the notional distribution date; or

(b) if arrangements are in existence by virtue of which any person could cause one or more of those conditions to cease to be fulfilled at some time during that or any later accounting period.

(4) In the application of section 239 in relation to surrendered advance corporation tax resulting from a surrender by either one of the consortium members under section 240, the reference in section 239(2) to the consortium company’s profits charged to corporation tax shall be construed as a reference to one half of so much of those profits as consists of ring fence profits.

(5) So much of any surplus advance corporation tax as consists of or includes surrendered advance corporation tax shall not be treated under section 239(4) as if it were advance corporation tax paid in respect of distributions made by the consortium company in a later accounting period unless the conditions in paragraphs (a) to (c) of subsection (1) above are fulfilled throughout that later period.

(6) In any case where—

(a) as a result of a surrender by one of the consortium members, the consortium company is treated as paying an amount of surrendered advance corporation tax which exceeds the limit applicable under section 239(2) (as modified by subsection (4) above), and

(b) that excess falls to be treated under section 239(4) as advance corporation tax paid by the consortium company in respect of distributions made in a later accounting period,

then, for the purposes of the application of section 239(2) (as modified by subsection (4) above) in relation to that later accounting period, the excess of the surrendered advance corporation tax shall be treated as resulting from a surrender by that one of the consortium members referred to in paragraph (a) above.

(7) Where section 240 has effect as mentioned in subsection (2) above, subsection (11) of that section shall have effect with the omission of paragraph (b) (and the word “and” immediately preceding it).

(8) Notwithstanding the provisions of subsection (1) above the consortium company shall not be regarded as a subsidiary for the purposes of section 498.

500 Deduction of PRT in computing income for corporation tax purposes

(1) Where a participator in an oil field has paid any petroleum revenue tax with which he was chargeable for a chargeable period, then, in computing for corporation tax the amount of his income arising in the relevant accounting period from oil extraction activities or oil rights, there shall be deducted an amount equal to that petroleum revenue tax.

(2) There shall be made all such adjustments of assessments to corporation tax as are required in order to give effect to subsection (1) above.

(3) For the purposes of subsection (1) above, the relevant accounting period, in relation to any petroleum revenue tax paid by a company, is—

(a) the accounting period of the company in or at the end of which the chargeable period for which that tax was charged ends; or

(b) if that chargeable period ends after the accounting period of the company in or at the end of which the trade giving rise to the income referred to above is permanently discontinued, that accounting period.

(4) If some or all of the petroleum revenue tax in respect of which a deduction has been made under subsection (1) above is subsequently repaid, that deduction shall be reduced or extinguished accordingly; and any additional assessment to corporation tax required in order to give effect to this subsection may be made at any time not later than six years after the end of the accounting period in which the first-mentioned tax was repaid.

(5) In this section “chargeable period” has the same meaning as in Part I of the 1975 Act.

501 Interest on repayment of PRT

Where any amount of petroleum revenue tax paid by a participator in an oil field is, under any provision of Part I of the 1975 Act, repaid to him with interest, the amount of the interest paid to him shall be disregarded in computing the amount of his income for the purposes of corporation tax.
