Whitehaven Coal Limited : Annual Report 2008
NOTES TO THE FINANCIAL STATEMENTS 30 JUNE 2008 4. DETERMINATION OF FAIR VALUES A number of the consolidated entity’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes based on the following methods. Where applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability. a) Property, plant and equipment The fair value of property, plant and equipment recognised as a result of a business combination is based on market values. The market value of property is the estimated amount for which a property could be exchanged on the date of valuation between a willing buyer and a willing seller in an arm’s length transaction after proper marketing wherein the parties had each acted knowledgeably, prudently and without compulsion. The market value of items of plant and equipment is based on the quoted market prices for similar items. b) Intangible assets The fair value of water access rights with indefinite useful lives is based on the outcome of recent transactions for similar assets within the same industry, less estimated costs of disposal. c) Inventories The fair value of inventories acquired in a business combination is determined based on its estimated selling price in the ordinary course of business less the estimated costs of completion and sale, and a reasonable profit margin based on the effort required to complete and sell the inventories. d) Derivatives The fair value of forward exchange contracts is based on their listed market price, if available. If a listed market price is not available, then fair value is estimated by discounting the difference between the contractual forward price and the current forward price for the residual maturity of the contract using a risk-free interest rate (based on government bonds). The fair value of foreign currency options is the estimated amount the consolidated entity would pay or receive to terminate the derivative at the balance sheet date, taking into account quoted market rates and the current creditworthiness of the counterparties. e) Non-derivative financial liabilities Fair value, which is determined for disclosure purposes, is calculated based on the present value of future principal and interest cash flows, discounted at the market rate of interest at the reporting date. For finance leases the market rate of interest is determined by reference to similar lease agreements. f) Share-based payment transactions The fair value of services received in return for share options granted to the directors is based on the fair value of share options granted, measured using Black Scholes barrier options techniques, incorporating the probability of the performance hurdles being met. The fair value of services received in return for share options granted to the senior employees is based on the fair value of share options granted, measured using a Black Scholes model. Measurement inputs include share price on measurement date, exercise price of the instrument, expected volatility (based on weighted average historic volatility adjusted for changes expected due to publicly available information of publicly listed companies operating in the same industry with similar operating characteristics), weighted average expected life of the instruments (based on historical experience of similar instruments and similar option holder characteristics), expected dividends, and the risk-free interest rate (based on government bonds). Service and non-market performance conditions attached to the transactions are not taken into account in determining fair value. 54
