84 Financial Statements for the year ended 30 June 2022 Page 33 of 60 Power and Water Corporation Notes to the financial statements for the year ended 30 June 2022 2.5 Critical accounting judgements and key sources of estimation uncertainty Capitalisation of borrowing costs on qualifying assets KKeeyy ssoouurrcceess ooff eessttiimmaattiioonn uunncceerrttaaiinnttyy Impairment write-back Impairment write-off Unbilled revenue Useful lives of property, plant and equipment A number of the consolidated entity's accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. In estimating the fair value of an asset or a liability, the consolidated entity uses market-observable data to the extent it is available. Where Level 1 inputs are not available, the consolidated entity engages third party qualified consultants to perform the valuation. Information about the valuation techniques and inputs used in determining the fair value of various assets and liabilities are disclosed in Notes 14 and 27. An entity must assess at the end of each reporting period whether there is any indication that an impairment loss recognised in prior periods for an asset other than goodwill may no longer exist or may have decreased. If any such indication exists, the entity must estimate the recoverable amount of that asset. The recoverable amount of an asset is the higher of fair value less cost to sell and the value in use of an asset. The consolidated entity has determined that the recoverable amount is represented by fair value less cost to sell. Determining whether an asset is impaired requires analysis of internal and external indicators. If such indication exists, the asset's carrying amount is tested against the asset's recoverable amount. The recoverable amount of an asset is the higher of fair value less cost to sell and the value in use of an asset. The consolidated entity has determined that the recoverable amount is represented by fair value less cost to sell. As per accounting standard AASB 15 'Revenue from contracts with customers', revenue is recognised to the extent that performance obligations are satisfied, it is probable that the revenue will not be reversed and the revenue can be reliably measured. Therefore, the consolidated entity estimates the amount of electricity, standard control services and water consumed at reporting date but that is yet to be billed. For further information on revenue recognition, refer to Note 2.3 (c). As described in Note 2.3 (l), the consolidated entity reviews the estimated useful lives of buildings and property, plant and equipment at the end of each reporting period and updates the useful life if expectations differ from previous estimates due to physical wear and tear, technical or commercial obsolescence and legal or other limits on the use of the assets. The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year: Under AASB 137 'Provisions, Contingent Liabilities and Contingent Assets', for contracts that are onerous the present obligation under the contract shall be recognised and measured as a provision. The definition of an onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs of a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfil it. Significant judgement is required when selecting the discount rate that shall be applied in determining the carrying amount of the provision. The consolidated entity has determined that any provision cash-flow workings shall be discounted using the long term bond yield rate of 3.77% (2021: 1.52%). Discount rate to be used in determining the provision for onerous contracts Under AASB 123 'Borrowing Costs', borrowing costs associated with qualifying assets must be capitalised. The definition of a qualifying asset for this purpose is any asset that necessarily takes a substantial period of time to get ready for its intended use or sale. The consolidated entity has determined that assets taking longer than 24 months to construct will be deemed qualifying assets and as such, borrowing costs associated with these assets will be capitalised. The following are the critical judgements, apart from those involving estimations (see below), that management have made in the process of applying the consolidated entity's accounting policies and that have the most significant effect on the amounts recognised in the financial statements: CCrriittiiccaall jjuuddggeemmeennttss iinn aappppllyyiinngg tthhee ccoonnssoolliiddaatteedd eennttiittyy''ss ppoolliicciieess The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods. Refer below for a discussion of critical accounting judgments and key sources of estimation uncertainty. In the application of the consolidated entity's accounting policies, management is required to make judgements, estimates and assumptions about carrying values of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.
