differences in gold price used in the estimation of mineral reserves.
Significant judgment is involved in the determination of useful life and residual values for the computation of
depreciation, depletion and amortization and no assurance can be given that actual useful lives and residual
values will not differ significantly from current assumptions. Impairment of Goodwill and Other Assets
Goodwill is tested for impairment annually or more frequently if there is an indication of impairment. The
carrying value of property, plant and equipment is reviewed each reporting period to determine whether
there is any indication of impairment. If the carrying amount of an asset exceeds its recoverable amount,
the asset is impaired and an impairment loss is recognized in the consolidated statement of operations. The
assessment of fair values, including those of the cash generating units for purposes of testing goodwill,
require the use of estimates and assumptions for recoverable production, timing of production, long-term
commodity prices, discount rates, net asset value multiples, foreign exchange rates, future capital
requirements and operating performance. Changes in any of the assumptions or estimates used in
determining the fair value of goodwill or other assets could impact the impairment analysis. Inventories
Expenditures incurred, and depreciation, depletion and amortization of assets used in mining and processing
activities are deferred and accumulated as the cost of ore in stockpiles, ore on leach pads, in-process and
finished metal inventories. These deferred amounts are carried at the lower of average cost or net realizable
value (“NRV”). Write-downs of ore in stockpiles, ore on leach pads, in-process and finished metal inventories
resulting from NRV impairments are reported as a component of current period costs. The primary factors
that influence the need to record write-downs include prevailing and long-term metal prices and prevailing
costs for production inputs such as labour, fuel and energy, materials and supplies, as well as re...
