a. Allowances for impairment losses of financial assets continued

Allowance for impairment losses related to a specific counterparty in the entire allowance for impairment losses established for the charges that are individually evaluated for impairment based on Managements best estimate of the present value of cash flows expected to be received. In calculating the allowance for impairment losses, management makes consideration of the financial condition of the counterparty and the net realizable value of the collateral received. Each asset is impaired are evaluated, and its completion strategy and estimation of cash flows considered recoverable are independently approved by the Credit Risk Management Unit. Evaluation of impairment losses collectively cover credit losses inherent in the portfolio bill with similar economic characteristics when there is objective evidence that impairment has occurred in the portfolio of the bill, but the decline in the value of the individual cannot be identified. In determining the need to establish loss reserves a collective impairment, management considers factors such as credit quality, size of portfolio, credit concentrations, and economic factors. In estimating the required reserves, the assumptions made to determine default and loss model to determine the required input parameters, based on historical experience and current economic conditions. The accuracy of this backup depends on how precise the estimated future cash flows to determine the individual reserves and the model assumptions and parameters used in determining collective reserves.

b. Determining fair values of financial instruments

In determining the fair value for financial assets and financial liabilities for which there is no observable market price, the Group uses the valuation techniques as described in Note 2c for financial instruments that are traded infrequently and a lack of price transparency, fair value is less objective and requires varying degrees of judgement depending on liquidity, concentration, uncertainty of market factors, pricing assumptions and other risks affecting the specific instrument.

c. Pension programs

Pension programs are determined based on actuarial valuation. The actuary valuation involves making assumptions about discount rate, expected rate of return investments, future salary increases, mortality rate, resignation rate and others refer to Note 2ai and 50. Any changes in those assumptions will impact to the liability balance of employee benefit obligations. The Group determines the appropriate discount rate at the end of each year including interest rate that should be used to determine the present value of estimated future cash outflows expected to settle the pension obligations. In determining the appropriate discount rate, the Group considers the interest rates of Government Bonds denominated in the similar currency with payments that will be made and have terms to maturity approximating the terms of the related employee benefit liability. Other key assumptions for pension obligations are determined based in part on current market conditions.

Significant estimates by management is required in determining the amount of deferred tax assets that can be recognized, based on current usage and the level of taxable income and future tax planning strategies. Banks do not take into account some of the benefits of deferred tax assets as management believes that deferred tax assets will not be recoverable in the future.

f. Depreciation and estimated useful life of fixed assets

Cost of acquisition of fixed assets are depreciated using the straight-line method based on their estimated economic useful life. Bank management estimates the useful lives of the assets between 5 five to 20 twenty years. Changes in the level of usage and technological developments could affect the economic useful lives and residual value of assets, and therefore future depreciation charges may be revised. The carrying value of fixed assets Bank disclosed in Note 18.

g. Impairment of non-financial assets
