Impairment of financial assets Fair value of financial instruments Goodwill impairment

| 133 Financial statements The amount of deferred tax assets recognised takes into account the likelihood the amount that can be used to offset payable taxes on future profits. Deferred tax related to fair value re-measurement of available-for- sale investments, which are recognised outside profit or loss, is also recognised outside profit or loss, i.e. in other comprehensive income and accumulated in the available-for-sale revaluation reserves. 3 Critical Accounting Estimates The Group’s accounting policies and use of estimates are integral to the reported amounts in the financial statements. Certain accounting estimates require management’s judgement in determining the appropriate methodology for valuation of assets and liabilities. Procedures are in place to ensure that methodologies are reviewed and revised as appropriate. The Group believes its estimates for determining the valuation of its assets and liabilities are appropriate. The following is a brief description of the Group’s critical accounting estimates that involve management’s valuation judgement.

3.1 Impairment of financial assets

It is the Group’s policy to recognise, through charges against profit, specific and general allowances in respect of estimated and inherent credit losses in its portfolio as described in Note 2.11. In estimating specific allowances, the Group assesses the gap between borrowers’ obligations to the Group and their repayment ability. The assessment takes into account various factors, including the economic or business outlook, the future profitability of the borrowers and the liquidation value of collateral. Such assessment requires considerable judgement. Another area requiring judgement is the calculation of general allowances, which are determined after taking into account historical data and management’s assessment of the current economic and credit environment, country and portfolio risks, as well as industry practices. Please refer to Risk Management section for a further description of the Group’s credit risk management.

3.2 Fair value of financial instruments

The majority of the Group’s financial instruments reported at fair value are based on quoted and observable market prices or on internally developed models that are based on independently sourced market parameters. The fair value of financial instruments without an observable market price in an active market may be determined using valuation models. The choice of model requires significant judgement for complex products especially those in the “Treasury” segment. Policies and procedures have been established to facilitate the exercise of judgement in determining the risk characteristics of various financial instruments, discount rates, estimates of future cash flows and other factors used in the valuation process. Please refer to Note 40 for details on fair valuation and fair value hierarchy of the Group’s financial instruments measured at fair value.

3.3 Goodwill impairment

The Group performs an impairment review to ensure that the carrying amount of a CGU to which goodwill is allocated does not exceed the recoverable amount of the CGU. Note 27 provides details of goodwill at the reporting date. The recoverable amount represents the present value of the estimated future cash flows expected to arise from continuing operations. Therefore, in arriving at the recoverable amount, management exercises judgement in estimating the future cash flows, growth rate and discount rate.
