Discounting and the Treatment of Taxes in Impairment Reviews
指出IAS 36要求的税前折现法因资产折旧方式不同而复杂多变，建议改用公司特定税后现金流并纳入递延税项进行减值测试。
Abstract: IAS 36 requires an asset's recoverable amount to be measured by discounting its pre‐tax rather than post‐tax cash flows. Although defined so as to produce the same value, the pre‐tax approach is claimed to be simpler and more reliable. The paper demonstrates that an appropriate pre‐tax discount rate varies between assets with different tax depreciation schedules and that it changes over time. Hence, pre‐tax discounting is likely to become complex. The paper advocates an amendment of the standard such that value in use is measured by company‐specific after‐tax cash flows, and such that deferred taxes are included in the impairment review.
