(1) For the purposes of section 437A, the present value of a lease is the
present value of the amounts mentioned in subsection (2).

(2) The amounts are—

(a) the amounts payable under the lease after the relevant time,
15and

(b) any residual amount.

(3) Subsection (2)(a) does not apply to amounts payable by the lessor or
to amounts that represent—

(a) charges for services, or

(b) 20qualifying UK or foreign tax to be paid by the lessor.

(4) Present value is to be calculated by using the interest rate implicit in
the lease.

apply in accordance with normal commercial criteria, including, in
25particular, generally accepted accounting practice (where
applicable).

(6) But if a rate cannot be determined in accordance with subsection (5),
the interest rate implicit in the lease is taken to be 1% above LIBOR.

applicable day for deposits for a term of 12 months in the
applicable currency,

(b) the applicable day is the day comprising or including the
relevant time (or, if that day is not a business day, the first

under the lease are payable.

(8) If—

(a) the lessee has an option to continue the lease for a period after
40expiry of its initial term, and

(b) it is reasonably certain at the relevant time that the lessee will
exercise that option,
