15(1)A qualifying company which incurs a ring fence loss (see paragraph 17) in a post-commencement period may claim supplement under this Part of this Schedule (“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 this Part of this Schedule or Part 4 of Schedule 19B) 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 set off under section 393 against trading income from the ring fence trade in succeeding accounting periods.
(3)Paragraph 74 of Schedule 18 to the Finance Act 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.
16(1)The amount of the post-commencement supplement for any post-commencement period in respect of which a claim under paragraph 15 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 twelve months, the amount of the supplement for the period (apart from this sub-paragraph) is to be reduced proportionally.
(3)Paragraphs 19 to 23 have effect for the purpose of determining the reference amount for a post-commencement period.
17(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 set off under section 393 against trading income from the trade in succeeding accounting periods,
so much of the loss as falls to be so set off is a “ring fence loss” of the company.
(2)In determining for the purposes of this Part of this Schedule how much of a loss incurred in a ring fence trade falls to be set off as mentioned in sub-paragraph (1)(b), the following assumption is to be made.
(3)The assumption is that every claim is made that could be made by the company under section 393A to set losses incurred in the ring fence trade against ring fence profits of earlier post-commencement periods.
(4)This paragraph is subject to paragraph 18 (special rule for straddling periods).
(5)This paragraph has effect for the purposes of this Part of this Schedule.
18(1)This paragraph applies if the period of the loss in which a ring fence loss is incurred is the deemed accounting period under paragraph 3(3) beginning on 1st January 2006 (“the deemed accounting period”).
(2)The amount of the 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, 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 the Capital Allowances Act in respect of relevant expenditure.
For the purposes of this step “relevant expenditure” means expenditure incurred by the company on or after 1st January 2006 which, but for that fact, would be qualifying E&A expenditure for the purposes of Schedule 19B.
For the purposes of this step a ring fence loss is attributable to those allowances to the extent that 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-1st January 2006 E&A allowances”.
Step 3
Deduct the qualifying Schedule 19B amount and the amount of the post-1st 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-1st January 2006 E&A allowances.
(3)In this paragraph “the straddling period”, in relation to a qualifying company, means an accounting period of the company—
(a)beginning before 1st January 2006, and
(b)ending on or after that date,
disregarding paragraph 3(3).
(4)In this paragraph 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 paragraph 17.
(5)This paragraph has effect for the purposes of this Part of this Schedule.
19(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,
(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 paragraph—
“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 immediately before 1st 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 immediately before 1st January 2006.
20(1)The ring fence pool consists of—
(a)the carried forward qualifying Schedule 19B amount,
(b)the company's ring fence losses, allocated to the pool in accordance with sub-paragraph (2)(a), and
(c)the company's post-commencement supplement, allocated to the pool in accordance with sub-paragraph (2)(b).
(2)The allocation of ring fence losses and post-commencement supplement to the pool is 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 Part of this Schedule.
(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 sub-paragraph (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 paragraph “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 immediately before 1st January 2006.
21(1)If one or more ring fence losses are set off under section 393 against any profits of a post-commencement period, reductions are to be made in that period in accordance with this paragraph.
(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 so set off.
(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 set off as mentioned in sub-paragraph (1).
(4)If the post-commencement period is the deemed accounting period under paragraph 3(3) beginning on 1st 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 paragraph to be the amount of the profits of the deemed accounting period.
(7)In this paragraph “the straddling period”, in relation to a qualifying company, means an accounting period of the company—
(a)beginning before 1st January 2006, and
(b)ending on or after that date,
disregarding paragraph 3(3).
22(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 paragraph.
(2)If, after making any reductions that fall to be made in accordance with paragraph 21, 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 paragraph 21, 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 paragraph 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 paragraph 21.
23For the purposes of this Part of this Schedule 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 paragraph 21 or 22.
