(1)Chapter I Of Part I of the [1968 c. 3.] Capital Allowances Act 1968 (industrial buildings and structures etc.) shall have effect with the following amendments, being amendments with respect to the calculation of balancing allowances and charges where a building or structure has at any time been used otherwise than as an industrial building or structure or for scientific research.
(2)For section 3(4) and (5) of that Act (calculation of balancing allowance and charge where no writing-down allowance has been made for part of the relevant period) there shall be substituted—
“(4)If for any part of the relevant period the building or structure was neither an industrial building or structure nor used for scientific research, subsections (4A) to (5) below shall have effect instead of subsections (2) and (3) above.
(4A)Subject to subsection (4C) below, where the sale, insurance, salvage or compensation moneys are not less than the capital expenditure, a balancing charge shall be made and the amount on which it is made shall be an amount equal to the allowances given.
(4B)Subject to subsection (4C) below, where there are no sale, insurance, salvage or compensation moneys or where those moneys are less than the capital expenditure, then—
(a)if the adjusted net cost of the building or structure exceeds the allowances given, a balancing allowance shall be made and the amount thereof shall be an amount equal to the excess;
(b)if the adjusted net cost of the building or structure is less than the allowances given, a balancing charge shall be made and the amount on which it is made shall be an amount equal to the shortfall.
(4C)No balancing charge or allowance shall be made under subsection (4A) or (4B) above on the occasion of a sale if by virtue of paragraph 4 of Schedule 7 to this Act the building or structure is treated as having been sold for a sum equal to the residue of the expenditure on its construction immediately before the sale.
(5)In subsections (4) to (4B) above and in this subsection—
" the relevant period " means the period beginning at the time when the building or structure was first used for any purpose and ending with the event giving rise to the balancing allowance or balancing charge except that where there has been a sale of the building or structure after that time and before that event the relevant period shall begin on the day following that sale or, if there has been more than one such sale, the last such sale ;
" the capital expenditure " means—
(a)where paragraph (b) of this definition does not apply, the capital expenditure incurred (or by virtue of section 5 of this Act deemed to have been incurred) on the construction of the building or structure ;
(b)where the person to or on whom the balancing allowance or balancing charge falls to be made is not the person who incurred (or is deemed to have incurred) that expenditure, the residue of that expenditure at the beginning of the relevant period,
together (in either case) with any amount to be added to the residue of that expenditure by virtue of section 4(11) of this Act;
" the allowances given " means the allowances referred to in subsection (6) of this section ;
" the adjusted net cost" means—
(a)where there are no sale, insurance, salvage or compensation moneys, the capital expenditure ;
(b)where those moneys are less than that expenditure, the amount by which they are less, reduced (in either case) in the proportion that the part, or the aggregate of the parts, of the relevant period for which the building or structure was an industrial building or structure or used for scientific research bears to the whole of that period ;
" scientific research " has the same meaning as in Part II of this Act”
(3)After section 4(10) of that Act there shall be inserted—
“(10A)Where, on the occasion of a sale, a balancing charge is made under section 3(4B)(b) of this Act in respect of the expenditure and, apart from this subsection, the residue of the expenditure immediately after the sale would by virtue of subsection (10) above be deemed to be greater than the net proceeds of the sale, the residue immediately after the sale shall be deemed for the purposes of this Chapter to be equal to the net proceeds.”
(4)In section 38 of the [1978 c. 42.] Finance Act 1978 (application of the said Chapter I to qualifying hotels) and in section 74 of the [1980 c. 48.] Finance Act 1980 (application of that Chapter to commercial buildings and qualifying hotels in enterprise zones) references to that Chapter shall be construed as references to that Chapter as amended by this section.
