SIGNIFICANT ACCOUNTING POLICIES (Continued) Financial instruments (Continued) Derecognition Financial assets are derecognised when the rights to receive cash flows from the assets expire or, the financial assets are transferred and the Group has transferred substantially all the risks and rewards of ownership of the financial assets. On derecognition of a financial asset, the difference between the asset’s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognised in other comprehensive income is recognised in profit or loss. Financial liabilities are derecognised when the obligation specified in the relevant contract is discharged, cancelled or expires. The difference between the carrying amount of the financial liability derecognised and the consideration paid and payable is recognised in profit or loss. 4. KEY SOURCES OF ESTIMATION UNCERTAINTY Key sources of estimation uncertainty The following is the key assumption 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. Estimated impairment of goodwill Determining whether goodwill is impaired requires an estimation of the value in use of the cash-generating units to which goodwill has been allocated. The value in use calculation requires the Group to estimate the future cash flows expected to arise from the cash-generating unit and a suitable discount rate in order to calculate present value. Where the actual future cash flows are less than expected, a material impairment loss may arise. As at 31 December 2009 and 2008, the carrying amounts of goodwill are approximately RMB12,168,000 (net of accumulated impairment loss of RMB8,006,000). Details of the recoverable amount calculation are disclosed in note 16.
