756.This section is based on section 79(2), (5) and (6) of CAA 1990. It provides rules for balancing allowances and charges which are equivalent to those for writing-down allowances.
757.Subsection (3) expands the meaning of “relevant circumstances”. These include looking forward to the extent to which the plant or machinery is likely to be used for purposes other than those of the qualifying activity. There may be other circumstances, including for example use in previous years.
758.Subsection (4) is new and is intended to clarify the position in future years of qualifying expenditure which was subject to a restriction of writing-down allowances under this section. See Note 38 in Annex 2.
