Commentary on Sections Glossary Structure of this Part Section 417: Determination of entitlement or liability
1453.This section is based on section 98(2) and (3) and section 100(1) of CAA 1990. It determines whether, in respect of qualifying expenditure, there is entitlement to an allowance or liability to a charge in a chargeable period. It is similar to section 55 in Part 2.
1454.There is no equivalent of sections 53 and 54 because qualifying expenditure is not pooled in this Part. The main factor common to the calculation of allowances in Part 2 is that writing-down allowances in this Part are also computed by applying a percentage to an amount which reduces from one chargeable period to the next – known as the reducing-balance basis.
1455.The meaning of “UQE” and “TDR” and when balancing allowances may be due are dealt with in detail later in the Chapter.
