379Lessee under long funding operating leaseU.K.
(1)This section applies if a company is the lessee of any plant or machinery under a long funding operating lease for the whole or part of any period of account.
(2)The deductions allowed in calculating the profits of the company for the period of account for corporation tax purposes are reduced.
(3)The amount of the reduction is so much of the expected gross reduction in value over the term of the lease as is attributable to the period of account.
(4)The expected gross reduction in value over the term of the lease is the starting value of the plant or machinery, less its expected end value.
(5)For the meaning of “starting value”, see section 380.
(6)The expected end value of plant or machinery is the amount which—
(a)at the commencement of the term of the lease is expected to be its market value at the end of the term, or
(b)if section 380(3) applies, would have been expected to be that value had that value been estimated at the commencement of the term.
(7)The expected gross reduction in value over the term of the lease that is attributable to the period of account is found by apportioning that reduction on a time basis according to the proportion of the term of the lease that falls in the period of account.
