(b) as a result of this section cannot be brought into account in a way that results in any reduction of what would otherwise be the company's ring fence profits,

the debit is to be brought into account for those purposes as a non-trading debit despite anything in section 297 of that Act.

(6) References in this section to a loan relationship, in relation to the borrowing of money, do not include a relationship to which Chapter 2 of Part 6 of CTA 2009 (relevant non-lending relationships) applies.

(b) falls, if the lease is a long funding operating lease, to be deductible in calculating the profits of the lessee for corporation tax purposes (after first making against any such expenditure any reductions falling to be made as a result of section 379 (lessee under long funding operating lease)).

But subsection (6) is subject to subsection (7).

(6) The expenditure is not allowable in calculating for the purposes of Part 3 of CTA 2009 the profits of the ring fence trade.

(7) Expenditure is not to be disallowed because of subsection (6) so far as the disposal mentioned in subsection (2) is made for a consideration which—

(b) is appropriated to meeting expenditure to be so incurred by the seller.

(8) If any expenditure—

(a) would, but for subsection (6), be allowable in calculating for the purposes of Part 3 of CTA 2009 the profits of the ring fence trade for an accounting period, but

(b) because of that subsection is not so allowable,

the expenditure is to be brought into account for the purposes of Part 5 of CTA 2009 (loan relationships) as if it were a non-trading debit in respect of a loan relationship of the lessee for that period.

(7) If there is an increase in the allowance, an amount of capital expenditure equal to the increase is to be treated, for the purposes of Part 2 or 6 of CAA 2001, as having been incurred by the company concerned in the adjustment period on an extension of, or addition to, the asset mentioned in subsection (2).

(8) If there is a reduction in the allowance, the company concerned is to be treated, for the purpose of determining its liability to corporation tax, as having received in the adjustment period, as income of the trade in connection with which the expenditure mentioned in subsection (2) was incurred, a sum equal to the amount of the reduction in the allowance.

(a) of a participator in an oil field, or

(b) of a person connected with the participator,

in making available an asset in a way which gives rise to tariff receipts or tax-exempt tariffing receipts of the participator are to be treated for the purposes of this Part as oil extraction activities.

(7) In determining for the purposes of subsection (2) whether a sum constitutes a tariff receipt or tax-exempt tariffing receipt of a person who is a participator, no account may be taken of any sum which—

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

(b) constitutes a tariff receipt or tax-exempt tariffing receipt of the participator.

But in relation to the person by whom such a sum is actually received, subsection (2) has effect as if the person were a participator and as if condition A were met.

(8) References in this section to a person connected with a participator include a person with whom the person is associated, within the meaning of paragraph 11 of Schedule 2 to the Oil Taxation Act 1983, but section 1176(1) of this Act (meaning of “connected” persons) does not apply for the purposes of this section.

(9) In this section—

• “tax-exempt tariffing receipt” has the meaning given by section 6A(2) of the Oil Taxation Act 1983, and

Abandonment guarantees U.K.

292 Expenditure on and under abandonment guarantees U.K.

(1) Subsection (2) applies if, as a result of section 3(1)(hh) of OTA 1975 (obtaining abandonment guarantee), expenditure incurred by a participator in an oil field is allowable (in whole or in part) for petroleum revenue tax purposes under section 3 of that Act.

(2) So far as that expenditure is so allowable, it is to be allowed as a deduction in calculating the participator's ring fence income.

(3) Subsection (4) applies if a payment is made by the guarantor under an abandonment guarantee.

(4) So far as any expenditure for which the relevant participator is liable is met, directly or indirectly, out of the payment, the expenditure is not to be regarded for corporation tax purposes as having been incurred by the relevant participator or any other participator in the oil field concerned.

(5) See also section 294 (payment under abandonment guarantee not immediately applied).

(6) In this Chapter—

• “abandonment guarantee” has the same meaning as it has for the purposes of section 105 of FA 1991 (see section 104 of that Act), and

• “the guarantor” and “the relevant participator” have the same meaning as in section 104 of that Act.

293 Relief for reimbursement expenditure under abandonment guarantees U.K.

(1) This section applies if—

(a) a payment (“the guarantee payment”) is made by the guarantor under an abandonment guarantee,

(b) as a result of the making of the guarantee payment, the relevant participator becomes liable under the terms of the abandonment guarantee to pay any sum to the guarantor, and

(c) expenditure is incurred, or consideration in money's worth is given, by the relevant participator in or towards meeting that liability.

(2) In this section “reimbursement expenditure” means expenditure incurred as mentioned in subsection (1)(c) or consideration (or the value of consideration) given as so mentioned; and any reference to the incurring of reimbursement expenditure is to be read accordingly.

(3) So much of any reimbursement expenditure as constitutes qualifying expenditure (see subsection (4)) is to be allowed as a deduction in calculating the relevant participator's ring fence income; and no part of the expenditure which is so allowed is to be otherwise deductible or allowable by way of relief for corporation tax purposes.

(4) The amount of reimbursement expenditure incurred in any accounting period by the relevant participator which constitutes qualifying expenditure is determined by the formula—

where—

A is the reimbursement expenditure incurred in the accounting period,

B is so much of the expenditure represented by the guarantee payment as, had it been incurred by the relevant participator, would have been taken into account (by way of capital allowance or a deduction) in calculating the relevant participator's ring fence income, and

C is the total of the sums which, at or before the end of the accounting period, the relevant participator is or has become liable to pay to the guarantor as mentioned in subsection (1)(b).

But this is subject to subsection (5).

(5) In relation to the guarantee payment, the total of the reimbursement expenditure (whenever incurred) which constitutes qualifying expenditure may not exceed whichever is the less of B and C in subsection (4).

(6) Any limitation on qualifying expenditure under subsection (5) is to be applied to the expenditure of a later accounting period in preference to an earlier one.

(7) For the purposes of this section, the expenditure represented by the guarantee payment is any expenditure—

(a) for which the relevant participator is liable, and

(b) which is met, directly or indirectly, out of the guarantee payment (and which, accordingly, because of section 292(4) is not to be regarded as expenditure incurred by the relevant participator).

(8) See also—

(a) section 294 (payment under abandonment guarantee not immediately applied), and

(b) section 295 which excludes amounts from subsection (1).

294 Payment under abandonment guarantee not immediately applied U.K.

(1) This section applies if—

(a) a payment made by the guarantor under an abandonment guarantee is not immediately applied in meeting any expenditure,

(b) the payment is for any period invested (either specifically or together with payments made by persons other than the guarantor) so as to be represented by, or by part of, the assets of a fund or account, and

(c) at a subsequent time, any expenditure for which the relevant participator is liable is met out of the assets of the fund or account.

(2) The references in sections 292(4) and 293(7) to expenditure which is met, directly or indirectly, out of the payment are to be read as references to so much of the expenditure for which the relevant participator is liable as is met out of those assets of the fund or account which, at the subsequent time mentioned in subsection (1)(c), it is just and reasonable to attribute to the payment.

295 Amounts excluded from section 293(1) U.K.

(1) This section applies if—

(a) the whole of the guarantee payment mentioned in section 293, or of the assets which under section 294 are attributed to the guarantee payment, is not applied in meeting liabilities of the relevant participator so mentioned which fall within section 104(1)(a) and (b) of FA 1991, and

(b) a sum representing the unapplied part of the guarantee payment or of those assets is repaid, directly or indirectly, to the guarantor so mentioned.

(2) Any liability of the relevant participator to repay that sum is to be excluded in determining the total liability of the relevant participator which falls within section 293(1)(b).

(3) The repayment to the guarantor of that sum is not to be regarded as expenditure incurred by the relevant participator as mentioned in section 293(1)(c).

Abandonment expenditure U.K.

296 Introduction to sections 297 and 298 U.K.

(1) Sections 297 and 298 apply if—

(a) paragraph 2A of Schedule 5 to OTA 1975 applies, or would apply if a claim under paragraph 2A(2) of that Schedule were made, and

(b) the default payment falls (in whole or part) to be attributed to the contributing participator under paragraph 2A(2) of that Schedule.

(2) In section 297 “the additional abandonment expenditure” means the amount which is attributed to the contributing participator as mentioned in subsection (1)(b) (whether representing the whole or only part of the default payment).

(3) In this Chapter “default payment”, “the defaulter” and “contributing participator” have the same meaning as in paragraph 2A of Schedule 5 to OTA 1975.

297 Relief for expenditure incurred by a participator in meeting defaulter's abandonment expenditure U.K.

(1) Relief by way of capital allowance, or a deduction in calculating ring fence income, is to be available to the contributing participator in respect of the additional abandonment expenditure if any such relief or deduction would have been available to the defaulter if—

(a) the defaulter had incurred the additional abandonment expenditure, and

(b) at the time that that expenditure was incurred the defaulter continued to carry on a ring fence trade.

(2) The basis of qualification for or entitlement to any relief or deduction which is available to the contributing participator under this section is to be determined on the assumption that the conditions in subsection (1)(a) and (b) are met.

(3) But, subject to subsection (2), any such relief or deduction is to be available in the same way as if the additional abandonment expenditure had been incurred by the contributing participator for the purposes of the ring fence trade carried on by the contributing participator.

298 Reimbursement by defaulter in respect of certain abandonment expenditure U.K.

(1) This section applies if expenditure is incurred, or consideration in money's worth is given, by the defaulter in reimbursing the contributing participator in respect of, or otherwise making good to the contributing participator, the whole or any part of the default payment.

(2) In this section “reimbursement expenditure” means expenditure incurred as mentioned in subsection (1) or consideration (or the value of consideration) given as so mentioned; and any reference to the incurring of reimbursement expenditure is to be read accordingly.

(3) Reimbursement expenditure is to be allowed as a deduction in calculating the defaulter's ring fence income (but this is subject to subsection (6)).

(4) Reimbursement expenditure received by the contributing participator is to be treated as a receipt (in the nature of income) of the participator's ring fence trade for the relevant accounting period (but this is subject to subsection (6)).

(5) Any additional assessment to corporation tax required in order to take account of the receipt of reimbursement expenditure by the contributing participator may be made at any time not later than 4 years after the end of the calendar year in which the reimbursement expenditure is so received.

(6) In relation to a particular default payment, reimbursement expenditure incurred at any time—

(a) is to be allowed as mentioned in subsection (3), and

(b) is to be taken into account as a result of subsection (4) in calculating the contributing participator's ring fence income,

only so far as, when aggregated with any reimbursement expenditure previously incurred in respect of that default payment, it does not exceed so much of the default payment as falls to be attributed to the contributing participator as mentioned in section 296(1)(b).

(7) The incurring of reimbursement expenditure is not to be regarded, by virtue of section 532 of CAA 2001 (the general rule excluding contributions), as the meeting of the expenditure of the contributing participator in making the default payment.

(8) In subsection (4) “the relevant accounting period” means—

(a) the accounting period in which the reimbursement expenditure is received by the contributing participator,

(b) if the contributing participator ceases to carry on the ring fence trade before the receipt of the reimbursement expenditure, the last accounting period of the trade, or

(c) if the contributing participator ceases to be within the charge to corporation tax in respect of the ring fence trade before the receipt of the reimbursement expenditure, the accounting period during or at the end of which the contributing participator ceased to be within the charge to corporation tax in respect of the trade.

299 Deduction of PRT in calculating income for corporation tax purposes U.K.

(1) This section applies if a participator in an oil field has paid any petroleum revenue tax with which the participator was chargeable for a chargeable period.

(2) In calculating for corporation tax the amount of the participator's income arising from oil extraction activities or oil rights in the relevant accounting period, there is to be deducted an amount equal to that petroleum revenue tax.

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

(4) In this section “the relevant accounting period”, in relation to any petroleum revenue tax paid by a company, means—

(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 company—

(i) ceases to carry on the trade giving rise to the income referred to above, or

(ii) ceases to be within the charge to corporation tax in respect of the trade,

that accounting period.

300 Effect of repayment of PRT: general rule U.K.

(2) The deduction is to be reduced or extinguished accordingly.

(3) Any additional assessment to corporation tax required in order to give effect to subsection (2) may be made at any time not later than 4 years after the end of the calendar year in which the petroleum revenue tax was repaid.

(4) This section is subject to section 301.

301 Effect of repayment of PRT: special rule U.K.

(1) This section applies if, in a case where paragraph 17 of Schedule 2 to OTA 1975 applies, an amount of petroleum revenue tax in respect of which a deduction has been made under section 299(2) is repaid as a result of an assessment under that Schedule or an amendment of such an assessment.

(2) As regards so much of that repayment as constitutes the appropriate repayment—

(a) section 300 does not apply, and

(b) the following provisions apply in relation to the company which is entitled to the repayment.

(3) In calculating for corporation tax the amount of the company's income arising in the relevant accounting period from oil extraction activities or oil rights there is to be added an amount equal to the appropriate repayment (but this is subject to subsections (4) and (5)).

(4) Subsection (5) applies if—

(a) two or more carried back losses give rise to the appropriate repayment,

(b) the operative chargeable period in relation to each of the carried back losses is not the same, and

(c) if this section were applied separately in relation to each of the carried back losses there would be more than one relevant accounting period.

(5) The appropriate repayment is to be treated as apportioned between each of the relevant accounting periods mentioned in subsection (4)(c) in such a way as to secure that the amount added as a result of subsection (3) in relation to each of those relevant accounting periods is what it would have been if—

(a) relief for each of the carried back losses for which there is a different operative chargeable period had been given by a separate assessment or amendment of an assessment under Schedule 2 to OTA 1975, and

(b) relief for a carried back loss accruing in an earlier chargeable period had been so given before relief for a carried back loss accruing in a later chargeable period.

(6) Any additional assessment to corporation tax required in order to give effect to the addition of an amount as a result of subsection (3) may be made at any time not later than 4 years after the end of the calendar year in which the repayment of petroleum revenue tax comprising the appropriate repayment is made.

• “the relevant accounting period”, in relation to the company which is entitled to the appropriate repayment, means—

  (a)

  the accounting period in or at the end of which the operative chargeable period ends,

  (b)

  if the company ceases to carry on its ring fence trade before the end of the operative chargeable period, the last accounting period of that trade, or

  (c)

  if the company ceases to be within the charge to corporation tax in respect of that trade before the end of the operative chargeable period, the accounting period during or at the end of which the company ceased to be within the charge to corporation tax in respect of that trade.

Application and interpretation U.K.

308 Qualifying companies U.K.

(1) This Chapter applies in relation to any company which—

(a) carries on a ring fence trade, or

(b) is engaged in any activities with a view to carrying on a ring fence trade.

(2) In this Chapter such a company is referred to as a “qualifying company”.

309 Accounting periods U.K.

  (a)

  which is the commencement period, or

  (b)

  which ends after the commencement period, and

(a) so much of the straddling period as falls before 1 January 2006, and

(b) so much of the straddling period as falls on or after that date,

are treated as separate accounting periods for the purposes of this Chapter.

(2) The accounting periods in respect of which claims are made need not be consecutive.

(3) A claim for supplement by the company under Schedule 19B to ICTA (exploration expenditure supplement) in respect of an accounting period is to count for the purposes of this section as a claim for supplement under this Chapter in respect of that accounting period.

(4) But, if the company makes a claim for supplement under this Chapter in respect of the deemed accounting period, any claim for supplement by the company under Schedule 19B to ICTA in respect of the Schedule 19B deemed accounting period is to be ignored for the purposes of this section.

(3) Condition B is that the expenditure is incurred in the course of oil extraction activities.

(4) Condition C is that the expenditure is incurred by a company with a view to carrying on a ring fence trade but before the company sets up and commences the ring fence trade.

(5) Condition D is that the expenditure—

(a) is subsequently allowable as a deduction in calculating the profits of the ring fence trade for the commencement period (whether or not any part of it is so allowable for any post-commencement period), or

(b) is relevant R&D expenditure incurred by an SME.

(6) For the purposes of this section, expenditure incurred by a company is “relevant R&D expenditure incurred by an SME” if—

(a) the company makes an election under section 1045 of CTA 2009 (alternative treatment for pre-trading expenditure: deemed trading loss) in respect of that expenditure, but

(b) the company does not make a claim for an R&D tax credit under section 1054 of that Act in respect of that expenditure.

(7) In the case of any qualifying pre-commencement expenditure which is relevant R&D expenditure incurred by an SME, the amount of that expenditure is treated for the purposes of this Chapter as being equal to 150% of its actual amount.

(8) In the case of any qualifying pre-commencement expenditure which is relevant R&D expenditure incurred by a large company, the amount of that expenditure is treated for the purposes of this Chapter as being equal to 125% of its actual amount.

there is, for the accounting period of company Q, an amount of unrelieved group ring fence profits equal to the whole of company X's taxable ring fence profits for its accounting period.

(4) If an accounting period of company X falls partly within an accounting period of company Q—

(a) there is an amount of unrelieved group ring fence profits for the accounting period of company Q, and

(b) that amount is an amount equal to the part of company X's taxable ring fence profits for its accounting period that is attributable, on an apportionment in accordance with section 1172, to the part of that period which falls within the accounting period of company Q.

Pre-commencement supplement U.K.

315 Supplement in respect of a pre-commencement accounting period U.K.

(1) If—

(a) a qualifying company incurs qualifying pre-commencement expenditure in respect of a ring fence trade, and

(b) the expenditure is incurred before the commencement period,

the company may claim supplement under this section (“pre-commencement supplement”) in respect of one or more pre-commencement periods.

(2) Any pre-commencement supplement allowed on a claim in respect of a pre-commencement period is to be treated as expenditure—

(a) which is incurred by the company in the commencement period, and

(b) which is allowable as a deduction in calculating the profits of the ring fence trade for that period.

(3) The amount of the supplement for any pre-commencement period in respect of which a claim under this section is made is the relevant percentage for that period of the reference amount for that period.

(4) If the pre-commencement period is a period of less than 12 months, the amount of the supplement for the period (apart from this subsection) is to be reduced proportionally.

(5) Sections 316 to 319 have effect for the purpose of determining the reference amount for a pre-commencement period.

316 The mixed pool of qualifying pre-commencement expenditure and supplement previously allowed U.K.

(1) For the purpose of determining the amount of any pre-commencement supplement, a qualifying company is to be taken to have had, at all times in the pre-commencement periods of the company, a continuing mixed pool of—

(a) the relevant amount (if any) which the company carries forward under Schedule 19B to ICTA,

(b) qualifying pre-commencement expenditure, and

(c) pre-commencement supplement.

(2) The pool is to be taken to have consisted of—

(a) the relevant amount (if any) which the company carries forward under Schedule 19B to ICTA,

(b) the company's qualifying pre-commencement expenditure, allocated to the pool for each pre-commencement period in accordance with subsection (3), and

(c) the company's pre-commencement supplement, allocated to the pool for each pre-commencement period in accordance with subsection (4).

(3) To allocate qualifying pre-commencement expenditure to the pool for any pre-commencement period, take the following steps—

• Step 1

  Count as eligible expenditure for that period so much of the qualifying pre-commencement expenditure mentioned in section 315(1) as was incurred in that period.

• Step 2

  Find the total of all the eligible expenditure for that period (amount E).

• Step 3

  If section 317 applies, reduce amount E in accordance with that section.

• Step 4

  If section 318 applies, reduce (or, as the case may be, further reduce) amount E in accordance with that section.

And so much of amount E as remains after making those reductions is to be taken to have been added to the pool in that period

(4) If any pre-commencement supplement is allowed on a claim in respect of a pre-commencement period, the amount of that supplement is to be taken to have been added to the pool in that period.

(5) In this section references to the relevant amount (if any) which the company carries forward under Schedule 19B to ICTA are to the amount (if any) in its mixed pool for the purposes of Part 3 of Schedule 19B to ICTA immediately before 1 January 2006.

317 Reduction in respect of disposal receipts under CAA 2001 U.K.

(1) This section applies in the case of the qualifying company if—

(a) it incurs qualifying pre-commencement expenditure in respect of a ring fence trade in any pre-commencement period,

(b) it would, on the relevant assumption, be entitled to an allowance under any provision of CAA 2001 in respect of that expenditure,

(c) an event occurs in relation to any asset representing the expenditure in any pre-commencement period, and

(d) the event would, on the relevant assumption, require a disposal value (the “deductible amount”) to be brought into account under any provision of CAA 2001 for any pre-commencement period.

(2) The relevant assumption is that the company was carrying on the ring fence trade—

(a) when the expenditure was incurred, and

(b) when the event giving rise to the disposal value occurred.

(3) For the purpose of allocating qualifying pre-commencement expenditure to the pool for each pre-commencement period—

(a) find the total amount of the disposal values in the case of all such events (amount D), and

(b) taking later periods before earlier periods, reduce (but not below nil) amount E for any pre-commencement period by setting against it so much of amount D as does not fall to be set against amount E for a later pre-commencement period.

318 Reduction in respect of unrelieved group ring fence profits U.K.

(1) This section applies if there is an amount of unrelieved group ring fence profits for a pre-commencement period.

(2) For the purpose of allocating qualifying pre-commencement expenditure to the pool for that period—

(a) find so much (if any) of amount E for that period as remains after any reduction falling to be made under section 317, and

(b) reduce that amount (but not below nil) by setting against it a sum equal to the aggregate of the amounts of unrelieved group ring fence profits for the period.

319 The reference amount for a pre-commencement period U.K.

For the purposes of section 315, the reference amount for a pre-commencement period is the amount in the pool at the end of the period—

(a) after the addition to the pool of any qualifying pre-commencement expenditure allocated to the pool for that period in accordance with section 316(3), but

(b) before determining, and adding to the pool, the amount of any pre-commencement supplement claimed in respect of the period.

320 Claims for pre-commencement supplement U.K.

(1) Any claim for pre-commencement supplement in respect of a pre-commencement period must be made as a claim for the commencement period.

(2) Paragraph 74 of Schedule 18 to FA 1998 (company tax returns etc: time limit for claims for group relief) applies in relation to a claim for pre-commencement supplement as it applies in relation to a claim for group relief.

Post-commencement supplement U.K.

321 Supplement in respect of a post-commencement period U.K.

(1) A qualifying company which incurs a ring fence loss (see section 323) in any post-commencement period may claim supplement under this section (“post-commencement supplement”) in respect of—

(a) that period, or

(b) any subsequent accounting period in which it carries on its ring fence trade.

(2) Any post-commencement supplement allowed on a claim in respect of a post-commencement period is to be treated for the purposes of the Corporation Tax Acts (other than the post-commencement supplement provisions or Part 4 of Schedule 19B to ICTA) as if it were a loss—

(a) which is incurred in carrying on the ring fence trade in that period, and

(b) which falls in whole to be used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce trading income from the ring fence trade in succeeding accounting periods.

(3) Paragraph 74 of Schedule 18 to FA 1998 (company tax returns etc: time limit for claims for group relief) applies in relation to a claim for post-commencement supplement as it applies in relation to a claim for group relief.

322 Amount of post-commencement supplement for a post-commencement period U.K.

(1) The amount of the post-commencement supplement for any post-commencement period in respect of which a claim under section 321 is made is the relevant percentage for that period of the reference amount for that period.

(2) If the post-commencement period is a period of less than 12 months, the amount of the supplement for the period (apart from this subsection) is to be reduced proportionally.

(3) Sections 325 to 329 have effect for the purpose of determining the reference amount for a post-commencement period.

(1) If—

(a) in any post-commencement period (“the period of the loss”) a qualifying company carrying on a ring fence trade incurs a loss in the trade, and

(b) some or all of the loss falls to be used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce trading income from the trade in succeeding accounting periods,

so much of the loss as falls to be so used is a “ring fence loss” of the company.

(2) In determining for the purposes of the post-commencement supplement provisions how much of a loss incurred in a ring fence trade falls to be used as mentioned in subsection (1)(b), the following assumptions are to be made.

(3) The first assumption is that every claim is made that could be made by the company under section 37 (relief for trade losses against total profits) to deduct losses incurred in the ring fence trade from ring fence profits of earlier post-commencement periods.

(4) The second assumption is that (where appropriate) section 42 (ring fence trades: further extension of period for relief) applies in relation to every such claim under section 37.

(5) This section is subject to section 324 (special rule for straddling periods).

(6) This section has effect for the purposes of the post-commencement supplement provisions.

324 Special rule for straddling periods U.K.

(1) This section applies if the period of the loss is the deemed accounting period under section 309(3) beginning on 1 January 2006 (“the deemed accounting period”).

(2) The amount of ring fence loss in the deemed accounting period is determined as follows—

• Step 1

  Calculate so much of the ring fence loss in the straddling period as, for the purposes of Part 4 of Schedule 19B to ICTA, is attributable to qualifying E&A allowances for the straddling period. The amount given by this step is “the qualifying Schedule 19B amount”.

• Step 2

  Calculate so much of the ring fence loss in the straddling period as is attributable to allowances for the straddling period under Part 6 of CAA 2001 in respect of relevant expenditure. For the purposes of this step “relevant expenditure” means expenditure incurred by the company on or after 1 January 2006 which, but for that fact, would be qualifying E&A expenditure for the purposes of Schedule 19B to ICTA. For the purposes of this step a ring fence loss is attributable to those allowances so far as the amount of the loss (less the qualifying Schedule 19B amount) does not exceed the amount of those allowances for that period. The amount given by this step is “the amount of the post-1 January 2006 E&A allowances”.

• Step 3

  Deduct the qualifying Schedule 19B amount and the amount of the post-1 January 2006 E&A allowances from the amount of the ring fence loss in the straddling period.

• Step 4

  Apportion the remaining amount of that loss (if any) to the deemed accounting period in proportion to the number of days in the deemed accounting period that fall in the straddling period. The amount given by this step is “the amount of the apportioned loss”

• Step 5

  The amount of the ring fence loss in the deemed accounting period is the amount of the apportioned loss plus the amount of the post-1 January 2006 E&A allowances.

(3) In this section “the straddling period”, in relation to a qualifying company, means an accounting period of the company—

(a) beginning before 1 January 2006, and

(b) ending on or after that date,

disregarding section 309(3).

(4) In this section references to the ring fence loss in the straddling period are to that loss determined on the assumption that the straddling period is the period of the loss for the purposes of section 323.

(5) This section has effect for the purposes of the post-commencement supplement provisions.

325 The pool of ring fence losses and the pool of non-qualifying Schedule 19B losses U.K.

(1) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is to be taken at all times in its post-commencement periods to have a continuing mixed pool (the “ring fence pool”) of—

(a) the carried forward qualifying Schedule 19B amount (if any),

(b) the company's ring fence losses, and

(c) post-commencement supplement.

(2) The ring fence pool continues even if the amount in it is nil.

(3) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is also to be taken in its post-commencement periods to have a non-qualifying pool consisting of the carried forward non-qualifying Schedule 19B amount.

(4) But the non-qualifying pool ceases to exist when the amount in it is reduced to nil.

(5) In this section—

• “the carried forward qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its qualifying pool for the purposes of Part 4 of Schedule 19B to ICTA immediately before 1 January 2006, and

• “the carried forward non-qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its non-qualifying pool for the purposes of Part 4 of Schedule 19B to that Act immediately before 1 January 2006.

326 The ring fence pool U.K.

(1) The ring fence pool consists of—

(a) the carried forward qualifying Schedule 19B amount (if any),

(b) the company's ring fence losses, allocated to the pool in accordance with subsection (2)(a), and

(c) the company's post-commencement supplement, allocated to the pool in accordance with subsection (2)(b).

(2) The allocation of ring fence losses and post-commencement supplement to the pool is made as follows—

(a) the amount of a ring fence loss is added to the pool in the period of the loss, and

(b) if any post-commencement supplement is allowed on a claim in respect of a post-commencement period, the amount of that supplement is added to the pool in that period.

(3) The amount in the ring fence pool is subject to reductions in accordance with the following provisions of this Chapter.

(4) If a reduction in the amount in the ring fence pool falls to be made in any accounting period, the reduction is to be made—

(a) after the addition to the pool of the amount of any ring fence losses allocated to the pool in that period in accordance with subsection (2)(a), but

(b) before determining, and adding to the pool, the amount of any supplement claimed in respect of the period,

and references to the amount in the pool are to be read accordingly.

(5) In this section “the carried forward qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its qualifying pool for the purposes of Part 4 of Schedule 19B to ICTA immediately before 1 January 2006.

327 Reductions in respect of utilised ring fence losses U.K.

(1) If one or more ring fence losses are used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce any profits of a post-commencement period, reductions are to be made in that period in accordance with this section.

(2) If the company has a non-qualifying pool, the amount in the non-qualifying pool is to be reduced (but not below nil) by setting against it a sum equal to the total amount used as mentioned in subsection (1).

(3) If—

(a) any of that sum remains after being so set against the amount in the non-qualifying pool, or

(b) the company does not have a non-qualifying pool,

the amount in the ring fence pool is to be reduced (but not below nil) by setting against it so much of that sum as so remains or (as the case may be) a sum equal to the total amount used as mentioned in subsection (1).

(4) If the post-commencement period is the deemed accounting period under section 309(3) beginning on 1 January 2006 (“the deemed accounting period”), the amount of the profits of the deemed accounting period is determined as follows.

(5) The amount of the profits of the straddling period is apportioned to the deemed accounting period in proportion to the number of days in the deemed accounting period that fall in the straddling period.

(6) The apportioned amount is taken for the purposes of this section to be the amount of the profits of the deemed accounting period.

(7) In this section “the straddling period”, in relation to a qualifying company, means an accounting period of the company—

(a) beginning before 1 January 2006, and

(b) ending on or after that date,

disregarding section 309(3).

328 Reductions in respect of unrelieved group ring fence profits U.K.

(1) If there is an amount of unrelieved group ring fence profits for a post-commencement period, reductions are to be made in that period in accordance with this section.

(2) If, after making any reductions that fall to be made in accordance with section 327, the company does not have a non-qualifying pool, the remaining amount in the ring fence pool is to be reduced (but not below nil) by setting against it a sum equal to the aggregate of the amounts of unrelieved group ring fence profits for the period.

(3) If, after making any reductions that fall to be made in accordance with section 327, the company has an amount in a non-qualifying pool, the amount in that pool is to be reduced (but not below nil) by setting against it a sum equal to the aggregate of the amounts of unrelieved group ring fence profits for the period.

(4) If any of that sum remains after being so set against the amount in the non-qualifying pool, the remaining amount in the ring fence pool is to be reduced (but not below nil) by setting against it so much of that sum as so remains.

(5) For the purposes of this section references to the remaining amount in the ring fence pool are references to so much (if any) of the amount in the ring fence pool as remains after making any reductions that fall to be made in accordance with section 327.

329 The reference amount for a post-commencement period U.K.

For the purposes of section 322 the reference amount for a post-commencement period is so much of the amount in the ring fence pool as remains after making any reductions required by section 327 or 328.

Chapter 6 U.K. Supplementary charge in respect of ring fence trades

330 Supplementary charge in respect of ring fence trades U.K.

(1) If a company carries on a ring fence trade in an accounting period, a sum equal to [F1 32%] of its adjusted ring fence profits for that period is to be charged on the company as if it were an amount of corporation tax chargeable on the company.

(3) The assumption is that financing costs are left out of account in calculating—

(a) the amount of the profits or loss of any ring fence trade of the company for an accounting period, and

(b) if for any such period the whole or part of any loss relief is surrendered to the company in accordance with section 305(1), the amount of that relief or part.

(4) See also section 331 (meaning of financing costs etc).

(5) This Chapter is subject to Chapter 7 (which contains provision about the reduction of the supplementary charge for certain new oil fields).

(f) any other costs arising from what would be considered in accordance with generally accepted accounting practice to be a financing transaction.

(4) If an amount representing the whole or part of a payment falling to be made by a company—

(a) falls (or would fall) to be treated as a finance charge under a finance lease for the purposes of accounts which relate to that company and one or more other companies and are prepared in accordance with generally accepted accounting practice, but

(b) is not so treated in the accounts of the company,

the amount is to be treated as a financing cost within subsection (3)(d).

(5) If—

(a) in calculating the adjusted ring fence profits of a company for an accounting period, an amount falls to be left out of account as a result of subsection (3)(d), but

(5) In the Corporation Tax (Treatment of Unrelieved Surplus Advance Corporation Tax) Regulations 1999 (S.I. 1999/358) or any further regulations made under section 32 of FA 1998 (unrelieved surplus advance corporation tax)—

(a) references to corporation tax do not include a sum chargeable on a company under section 330(1) as if it were corporation tax, and
