(h) Impairment of assets
Financial assets (including accounts receivable)
The Company reviews its accounts receivable at least at each reporting date to determine whether there is objective evidence that it is impaired.
The Company considers evidence of impairment for accounts receivable when the amounts are past due or when other objective information is received that a specific counterparty may default. Accounts receivable that are not considered to be individually impaired are reviewed for impairment in groups, using historical trends of the probability of default, timing of recoveries and the amount of loss incurred, adjusted for management's judgment as to whether current economic and credit conditions are such that the actual losses are likely to be greater or less than suggested by historical trends.
An impairment loss is calculated as the difference between an asset's carrying amount and the present value of the estimated future cash flows discounted at the asset's original effective interest rate. Losses are recognized in profit or loss and reflected in an allowance account against receivables. When subsequent events cause the amount of impairment loss to decrease, the decrease in impairment loss is reversed through profit or loss.
Non-financial assets
The carrying amounts of the Company's non-financial assets, other than inventories are reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists, then the asset's recoverable amount is estimated.
The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less costs of disposal. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. For the purpose of impairment testing, if it is not possible to estimate the recoverable amount of an individual asset, the asset is included in the cash-generating unit to which it belongs and the recoverable amount of the cash-generating unit is estimated. As a result, some assets are tested individually for impairment and some are tested at the cash-generating unit level. A cash-generating unit is the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets.
An impairment loss is recognized if the carrying amount of an asset or its cash-generating unit exceeds its estimated recoverable amount. Impairment losses are recognized in profit or loss. Impairment losses recognized in respect of cash-generating units are allocated first to reduce the carrying amount of any goodwill allocated to the units and then to reduce the carrying amounts of the other assets in the unit on a pro-rata basis.
