As indicated at B3.332, the availability of writing-down allowances, balancing allowances and balancing charges for a chargeable period depends on the available qualifying expenditure 'AQE' in the pool and the total of any disposal receipts 'TDR' to be brought into account in that pool for that period (see B3.334). The general rule¹ is that AQE is the sum of:

1. Ìý

   •ÌýÌýÌýÌý qualifying expenditure allocated to the pool in the chargeable period under the initial allocation rules described below, and

2. Ìý

   •ÌýÌýÌýÌý 'unrelieved qualifying expenditure' (see below) brought forward from the pool from the previous chargeable period

For the meaning of chargeable period, see B3.102.

There are other specific provisions which direct qualifying expenditure to be allocated to a pool and provisions which exclude certain expenditure². They are dealt with in the appropriate articles elsewhere in this Division.
