Commentary on Sections Glossary Structure of Part 2 Section 77: Car used partly for purposes other than those of qualifying activity
372.This section is based on section 34(5) of CAA 1990. It deals with cars that are partly used for purposes other than those of the qualifying activity.
373.There is no disposal event when a car within this Chapter begins to be used in this way. So the single asset pool under this Chapter takes the place of the single asset pool which would otherwise be required by Chapter 15. But the rules in this section are similar to those in Chapter 15 as regards the just and reasonable reduction to any allowances and charges.
374.Subsection (1) provides that no balancing allowance or charge arises when the car begins to be used partly for purposes other than those of the qualifying activity. See Note 20 in Annex 2.
375.Subsection (4) deals with calculation of unrelieved qualifying expenditure carried forward. In saying that any reduction of a writing-down allowance under this section is to be disregarded, this subsection goes further than section 34(5) of CAA 1990. See Note 21 in Annex 2
