C2.1217 Grant of a lease out of a wasting lease
Where a lease is granted out of a lease which is a wasting asset, the part disposal formula1 does not apply to determine the allowable expenditure which may be deducted in the computation of chargeable gains2.
Instead, only that part of the expenditure which wastes away over the period of the sublease may be deducted from the consideration3 for the sublease4. These provisions5 are on the curved line basis for land6 and on the straight line basis for other assets7.
