SINGAPORE TECHNOLOGIES ENGINEERING LTD Annual Report 2011129NOTES TO THE FINANCIAL STATEMENTS31 December 2011(Currency - <strong>Singapore</strong> dollars unless o<strong>the</strong>rwise stated)3. Summary of significant accounting policies (continued)(h)Impairment (continued)(i)Non-derivative <strong>financial</strong> assets (continued)Financial assets carried at amortised cost (continued)In assessing collective impairment, <strong>the</strong> Group uses his<strong>to</strong>rical trends of <strong>the</strong> probability of default, <strong>the</strong> timing of recoveries and <strong>the</strong>amount of loss incurred, adjusted for management’s judgement as <strong>to</strong> whe<strong>the</strong>r current economic and credit conditions are such that <strong>the</strong>actual losses are likely <strong>to</strong> be greater or less than suggested by his<strong>to</strong>rical trends.If <strong>the</strong>re is objective evidence that an impairment loss on loans and receivables or held-<strong>to</strong>-maturity investments carried at amortisedcost has been incurred, <strong>the</strong> amount of <strong>the</strong> loss is measured as <strong>the</strong> difference between <strong>the</strong> asset’s carrying amount and <strong>the</strong> presentvalue of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at <strong>the</strong> <strong>financial</strong> asset’soriginal effective interest rate (i.e., <strong>the</strong> effective interest rate computed at initial recognition). The carrying amount of <strong>the</strong> asset shall bereduced ei<strong>the</strong>r directly or through use of an allowance account. The amount of <strong>the</strong> loss shall be recognised in profit or loss.If, in a subsequent period, <strong>the</strong> amount of <strong>the</strong> impairment loss decreases and <strong>the</strong> decrease can be related objectively <strong>to</strong> an even<strong>to</strong>ccurring after <strong>the</strong> impairment was recognised, <strong>the</strong> previously recognised impairment loss is reversed. Any subsequent reversal of animpairment loss is recognised in profit or loss, <strong>to</strong> <strong>the</strong> extent that <strong>the</strong> carrying value of <strong>the</strong> asset does not exceed its amortised cost at<strong>the</strong> reversal date.Financial assets carried at costIf <strong>the</strong>re is objective evidence that an impairment loss on an unquoted equity instrument that is not carried at fair value because itsfair value cannot be reliably measured, or on a derivative asset that is linked <strong>to</strong> and must be settled by delivery of such an unquotedequity instrument has been incurred, <strong>the</strong> amount of <strong>the</strong> loss is measured as <strong>the</strong> difference between <strong>the</strong> asset’s carrying amount and<strong>the</strong> present value of estimated future cash flows discounted at <strong>the</strong> current market rate of return for a similar <strong>financial</strong> asset. The lossrecognised is not reversed in future periods.Available-for-sale <strong>financial</strong> assetsIf an available-for-sale <strong>financial</strong> asset is impaired, an amount comprising <strong>the</strong> difference between its cost (net of any principal paymentand amortisation) and its current fair value, less any impairment loss previously recognised in <strong>the</strong> income statement, is transferredfrom equity <strong>to</strong> profit or loss.Reversals in respect of impairment losses on equity instruments classified as available-for-sale are recognised in o<strong>the</strong>r comprehensiveincome. Reversals of impairment losses on debt instruments are reversed through profit or loss, if <strong>the</strong> increase in fair value of <strong>the</strong>instrument can be objectively related <strong>to</strong> an event occurring after <strong>the</strong> impairment loss was recognised in profit or loss.(ii)O<strong>the</strong>r non-<strong>financial</strong> assetsThe Group assesses at each reporting date whe<strong>the</strong>r <strong>the</strong>re is an indication that its non-<strong>financial</strong> assets, o<strong>the</strong>r than goodwill, investmentproperty, inven<strong>to</strong>ries and deferred tax assets, may be impaired. Goodwill is reviewed for impairment, annually or more frequently ifevents or changes in circumstances indicate that <strong>the</strong> carrying value may be impaired. If any such indication exists, <strong>the</strong> Group makesan estimate of <strong>the</strong> asset’s recoverable amount. An impairment loss is recognised if <strong>the</strong> carrying amount of an asset or its related cashgeneratingunit (“CGU”) exceeds its estimated recoverable amount.
