(1)This section applies if—
(a)a credit is brought into account by a company in a period of account (“the period of the credit”),
(b)the credit reverses (in whole or in part) a debit brought into account in a previous period of account of the company,
(c)the debit (or part of it) represents expenses of management deductible under section 1219 for an accounting period which ends before, or at the same time as, the period of the credit, and
(d)the expenses of management are not expenses brought forward to that period under section 1223.
For cases involving an absence of accounts see also section 1231.
(2)The reversal amount (see section 1230) is dealt with in accordance with subsection (3) or (5).
(3)If the period of the credit coincides with an accounting period of the company—
(a)the reversal amount is, as far as possible, applied in reducing (but not below nil) the company's expenses of management belonging to that period, and
(b)if not all of the amount can be applied in that way, the remainder is to be treated as a receipt of the company chargeable for that period under the charge to corporation tax on income.
(4)For the purposes of subsection (3), the expenses of management belonging to a period are the expenses of management that are deductible for that period, excluding any amounts brought forward under section 1223.
(5)If the period of the credit does not coincide with an accounting period of the company—
(a)the reversal amount is apportioned between any accounting periods that fall within the period of the credit, and
(b)paragraphs (a) and (b) of subsection (3) are applied to any amount that is apportioned to an accounting period.
(6)An apportionment under subsection (5) must be made in accordance with section 1311 (time basis) or, if it appears that that method would work unreasonably or unjustly, on a just and reasonable basis.
