(1)This section applies so far as in an accounting period a company is a party to a derivative contract for the purposes of a trade it carries on.
(2)The credits in respect of the contract for the period are treated as receipts of the trade which are to be brought into account in calculating the profits of the trade for that period.
(3)The debits in respect of the contract for the period are treated as expenses of the trade which are deductible in calculating those profits.
(4)So far as subsection (3) provides for any amount to be deductible, it applies despite anything in—
(a)section 53 (capital expenditure),
(b)section 54 (expenses not wholly and exclusively for trade and unconnected losses), or
(c)section 59 (patent royalties).
(5)For cases in which this section does not apply, see—
