The amount of the unrelieved qualifying expenditure is—

the excess less the writing-down allowance made for the period, or

if no writing-down allowance is claimed for the period, the excess.

A “
cash basis deductible amount

Where a person has unrelieved qualifying expenditure to carry forward from a chargeable period that is not expenditure allocated to a single asset pool,
any cash basis deductible amount
is to be determined on such basis as is just and reasonable in all the circumstances.
