410.This section is based on section 38A(4) and (5) of CAA 1990. It deals with circumstances in which this Chapter only applies to part of the capital expenditure on plant or machinery. If that happens then the expenditure within this Chapter is treated as expenditure on a separate asset from the expenditure outside it. If necessary, apportionments are made between that part to which this Chapter applies and that part to which it does not.
