38 Speciality Metals International Limited Annual Report 2020 Notes to the Consolidated Financial Statements continued NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Page | 39 When a Group entity transacts with a joint operation in which a Group entity is a joint operator (such as a purchase of assets), the Group does not recognise its share of the gains and losses until it resells those assets to a third party. The requirements of IAS 36 are applied to determine whether it is necessary to recognise any impairment loss with respect to the Group’s investment in an associate or a joint venture. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs of disposal) with its carrying amount. Any impairment loss recognised is not allocated to any asset, including goodwill that forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognised in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases. (e) Property, Plant and Equipment Plant and equipment is stated at cost less accumulated depreciation and any impairment in value. Depreciation is calculated either on a diminishing value or straight-line basis over the estimated useful life of the asset. Plant and equipment useful life ranges from 1 – 10 years. Impairment The carrying values of plant and equipment are reviewed for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. An item of plant and equipment is derecognised upon disposal. Any gain or loss arising on de-recognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is included in the income statement in the period the item is derecognised. (f) Inventory Inventories are valued at the lower of cost and net realisable value as per AASB 102 with the exception of the 7 million tonnes of stockpiled inventory which was recognised at fair value as part of the business combination upon the acquisition of Mt Carbine Quarries Pty Ltd on 28 June 2019. This inventory will be consumed on a units of operation basis. The cost of partly-processed and saleable products is generally the cost of production, including: - labour costs, materials and contractor expenses which are directly attributable to the processing of quarry material or the production of tungsten concentrate; - the depreciation of property, plant and equipment used in the processing of quarry material or the production of tungsten concentrate; and - Production overheads. (g) Borrowings Borrowings are initially measured at fair value, and are subsequently measured at amortised cost, using the effective interest rate method. Any difference between the proceeds (net of transaction costs) and the settlement or redemption of borrowings is recognised over the term of the borrowings in accordance with the accounting policy for borrowing costs. Borrowings are classified as current unless the Group has an unconditional right to defer the settlement of the liability for at least 12 months after the reporting date. (h) Recoverable Amount of Assets At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. Where an indicator of impairment exists, the Group makes a formal estimate of the recoverable amount. Where the carrying amount of an asset exceeds its recoverable amount the asset is considered impaired and is written down to its recoverable amount. Recoverable amount is the greater of fair value less costs to sell and value in use. (i) Exploration, Evaluation, Development and Restoration Costs Exploration and Evaluation Exploration and evaluation expenditure incurred by or on behalf of the Company is accumulated separately for each area of interest. Such expenditure comprises net direct costs and an appropriate portion of related overhead expenditure but does not include general overheads or administrative expenditure not having a specific connection with a particular area of interest. Exploration and evaluation costs in relation to separate areas of interest for which rights of tenure are current are brought to account in the year in which they are incurred and carried forward provided that: § such costs are expected to be recouped through successful development and exploitation of the area, or alternatively through its sale; or
