Notes to the financial statements (continued) Section 3: Operational assets and liabilities (continued) 11. Property, plant and equipment, and intangible assets (continued) C. Impairment of non-financial assets
Impairment losses are recognised in profit or loss and, where material, are disclosed separately. Any impairment losses recognised in previous years are assessed at the end of each reporting date for any indications the loss has decreased or no longer exists. An impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortisation, if no impairment loss had been recognised. D. Amounts recognised in statement of financial position See table 19 below.
At each reporting date, Western Power considers any indicators of impairment to non-financial assets, that is, events or changes in circumstances that indicate the carrying value may not be fully recoverable. If an indication exists, the asset’s recoverable amount is estimated. Where the asset’s carrying amount exceeds the recoverable amount an impairment loss is recognised for the difference. The recoverable amount is the greater of an asset’s or groups of assets (being cash generating units ( CGU )) value in use and its fair value less costs to sell. Recoverable amount 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.
