Introduction Details of the Schedule Part 2: Commencement for Part 14B
18.Where the conditions apply and use of relevant carried-forward amounts is restricted, this will take effect for accounting periods beginning on or after 18 March 2015.
19.Where the rules apply to a company with an accounting period straddling 18 March 2015, that period will be treated as two separate accounting periods for the purposes of this Part, and the restriction on relevant carried-forward amounts will apply in the split period treated as commencing 18 March 2015. The default is a split on a time basis, unless that basis is unjust or unreasonable.
20.This treatment will split any loss for the whole accounting period into a loss in the two periods, or any profit for the whole accounting period into a profit in the two periods.
21.The split operates at the level of amounts brought into account for the purposes of calculating the taxable total profits of the company. Hence if the restriction in subsection 730G(10) applies within a period straddling 18 March 2015:
	where carried-forward losses or non-trading loan relationship deficits are restricted, the amount of total profits calculated in section 4(3) of CTA 2010 will be higher, increasing the amount of total profits against which relief can be given at Step 2 of section 4(2) in the calculation of taxable total profits; and
	where management expenses are restricted, which are the first of all reliefs against total profits, the balance of total profits left available for relief at Step 2 of section 4(2) will be higher in the calculation of total profits; and
	these increased amounts will only be reflected in the period deemed to commence on 18 March 2015.
22.The split applies only so far as it is necessary for the purposes of this Part.
23.The Part makes no mention regarding when arrangements may have been entered into, so the rules will apply regardless of when this was.
