59 Westgold Resources Limited Annual Report 2022 2. S UMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (o) I mpairment of non-financial assets (continued) The estimated cash flows are based on expected future production, metal selling prices, operating costs and forecast capital expenditure based on life-of-mine plans. VIU does not reflect future cash flows associated with improving or enhancing an asset’s performance, whereas anticipated enhancements to assets are included in FVLCD calculations. Impairment losses of continuing operations, including impairment on inventories, are recognised in the profit and loss. For such properties, the impairment is recognised in other comprehensive income up to the amount of any previous revaluation. For assets, an assessment is made at each reporting date to determine whether there is an indication that previously recognised impairment losses no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. A previously recognised impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognised. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised for the asset in prior years. Such reversal is recognised in profit or loss. (p) Provisions Provisions are recognised when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Provisions are measured at the present value of management’s best estimate of the expenditure required to settle the present obligation at the reporting date. The discount rate used to determine the present value reflects current market assessments of the time value of money and the risks specific to the liability. The increase in the provision resulting from the passage of time is recognised in finance costs. (q) Lease liabilities The Group has lease contracts for various items of mining equipment, motor vehicles and buildings used in its operations. Upon adoption of AASB 16, all leases with the exception of short term (under 12 months) and low value leases, are recognised on the balance sheet as a right-ofuse asset and a corresponding interest-bearing liability. Lease costs are recognized in the income statement over the lease term in the form of depreciation on the right-ofuse asset and finance charges representing the unwinding of the discount on the lease liability. The Group recognises leases entered into after 1 July 2019 using the interest rate implicit in the lease. (r) Interest revenue Revenue is recognised using the effective interest method. This is a method of calculating the amortised cost of a financial asset and allocating the interest income over the relevant period using the effective interest rate, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to the net carrying amount of the financial asset. (s) Revenue from contracts with customers Revenue from contracts with customers is recognised when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services. The Group has concluded that it is the principal in its revenue contracts because it typically controls the goods or services before transferring them to the customer. Gold bullion sales For bullion sales, most of this is sold under a long-term sales contract with the refiner and forward sale agreements with with Citibank N.A. The only performance obligation under the contract is the sale of gold bullion. Revenue from bullion sales is recognised at a point in time when control passes to the buyer. This generally occurs after the unrefined doré is outturned and the Group either instructs the refiner to purchase the outturned fine metal or advises the refiner to transfer the gold to the bank by crediting the metal account of the bank. As all performance obligations are satisfied at that time, there are no remaining performance obligations under the contract. The transaction price is determined at transaction date and there are no further adjustments to this price. A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration from the customer. If a customer pays consideration before the Group transfers goods or services to the customer, a contract liability is recognised when the payment is made, or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Group performs under the contract. The Group applies the practical expedient to not adjust the promised consideration for the effects of a significant financing component where the period between the transfer of the refined gold to a customer and the receipt of the advance is one year or less. For long-term advances from customers the transaction price is discounted, using the rate that would be reflected in a separate transaction between the Group and its customers at contract inception, to take into consideration the significant financing component.
