The National Titanium Dioxide Company Limited (Cristal)
NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
FOR THE SIX MONTHS ENDED 30 JUNE 2017
2 BASIS OF PREPARATION AND CONSOLIDATION (continued)
Other intangible assets also include patents and license costs. These assets are amortized using the straight-line method over the shorter of their estimated useful lives or the terms of the related agreements.
2.11 Exploration and evaluation costs
Pre-license costs are recognized in the consolidated statement of profit or loss.
Exploration and evaluation costs, including the costs of acquiring licenses, are capitalized as exploration and evaluation assets (“E&E assets”) on an area of interest basis pending determination of the technical feasibility and commercial viability of the project. When a license is relinquished or a project is abandoned, the related costs are recognized in the interim condensed consolidated statement of profit or loss immediately.
E&E assets are assessed for impairment if (i) sufficient data exists to determine technical feasibility and commercial viability, and (ii) facts and circumstances suggest that the carrying amount exceeds the recoverable amount (see the impairment of assets policy note). For the purposes of impairment testing,
E&E assets are allocated to cash-generating units consistent with the determination of areas of interest.
Once the technical and commercial viability of extracting a mineral resource is determined, E&E assets attributable to those reserves are first tested for impairment and then reclassified from E&E assets to mine development assets within property and equipment.
Expenditure deemed to be unsuccessful is recognized in the interim condensed consolidated statement of profit or loss immediately.
2.12 Impairment of non-financial assets
Goodwill and assets with indefinite life are tested for impairment annually.
For other assets, the Group assesses at each reporting date whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or cash generating unit’s (“CGU”) fair value less costs of disposal and its value in use. It is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. Where the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.
In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less costs of disposal, recent market transactions are taken into account. If no such transactions can be identified, an appropriate valuation model is used. These calculations are corroborated by valuation multiples, quoted share prices for publicly traded subsidiaries or other available fair value indicators.
The Group bases its impairment calculation on detailed budgets and forecasts which are prepared separately for each of the Group’s CGU to which the individual assets are allocated. These budgets and forecast calculations generally cover a period of five years. A long-term growth rate is calculated and applied to project future cash flows after the fifth year.
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 the interim condensed consolidated statement of profit or loss.
Impairment recognized previously on goodwill is not reversed.
