PAKISTANOILFIELDS LIMITED
The lease liability is measured at amortised cost using the effective interest method. It is remeasured
when there is a change in future lease payments arising from a change in an index or rate, if there
is a change in the Company’s estimate of the amount expected to be payable under a residual
value guarantee, or if the Company changes its assessment of whether it will exercise a purchase,
extension or termination option.
When the lease liability is remeasured in this way, a corresponding adjustment is made to the
carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of
the right-of-use asset has been reduced to zero.
Variable lease payments are recongnised in profit or loss in the period in which the condition that
triggers those payments occurs.
The Company has opted not to recognize right of use asssets for short-term leases i.e. leases with
a term of twelve(12) months or less. The payments associated with such leases are recognized in
profit or loss when incurred.
