186 Fixture on which an industrial buildings allowance has been madeU.K.
(1)This section applies if—
(a)a person (“the past owner”) has at any time claimed an allowance to which he is entitled under Part 3 (industrial buildings allowances) in respect of expenditure which was or included expenditure on the provision of plant or machinery,
(b)the past owner has transferred the interest which is the relevant interest for the purposes of Part 3, and
(c)the current owner of the plant or machinery makes a claim in respect of expenditure (“new expenditure”) incurred—
(i)on the provision of the plant or machinery, and
(ii)at a time when it is a fixture in the building.
(2)If the new expenditure exceeds the maximum allowable amount, the excess is to be left out of account in determining the current owner’s qualifying expenditure.
(3)The maximum allowable amount is—
where—
F is the part of the consideration for the transfer by the past owner that is attributable to the fixture,
T is the total consideration for that transfer, and
R is the residue of qualifying expenditure attributable to the relevant interest immediately after that transfer, calculated on the assumption that the transfer was a sale of the relevant interest.
(4)For the purposes of this section the current owner of the plant or machinery is—
(a)the person to whom the past owner transferred the relevant interest, or
(b)any person who is subsequently treated as the owner of the plant or machinery.
(5)In this section “building” and “residue of qualifying expenditure” have the same meaning as in Part 3.
