(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.
