In order to quantify the loss eligible for relief, the foreign
loss is to be recomputed in accordance with UK principles, (
CTM81560).
All of the computational rules in FA96 need to be applied to
arrive at profits or losses on loan relationships, and similarly
the computational rules in FA02/SCH26 need to be applied to arrive
at profits or losses on derivative contracts.
This takes in not only the basic computational rules (found
at FA96/S85A & 85B for loan relationships, and FA96/PARA17A -
17C for derivative contracts) but in particular will include:
The Corporate Finance Manual provides details of how to compute profits and losses arising on loan relationships and derivative contracts. Guidance on loan relationships is at CFM5000 onwards, and on derivative contracts at CFM13000 onwards.
