In subsection
(3)
, “
the connected companies
” refers to the company to which this section is being applied and each company with which it is connected; and the references to their expenditure are to the aggregate of each of their expenditures.
5
Expenditure forms part of a company’s total relevant expenditure for an accounting period if—
a
in accordance with generally accepted accounting practice, it is brought into account in calculating the profits for the period of any trade carried on by the company,
b
it is expenditure in respect of which the company is, for the period, entitled to relief under section 1045, or
