In relation to overseas leasing, allowances in respect of the relevant expenditure are calculated separately from the main plant and machinery pool and, except as mentioned below, any other pool. Each asset is treated as if it were pooled with other such assets (i.e. other overseas leasing assets). The expenditure on such assets is included in a class pool (the overseas leasing pool).
The pooling arrangement does not override those special provisions which provide for each asset to be treated individually (as single asset pools), although the restrictions on allowances then apply equally to those individual assets.
