Notes to the Consolidated Financial Statements for the year ended March 31, 2021 (contd.) Financial Statements GlaxoSmithKline Pharmaceuticals Limited 186 Note 2 : Critical estimates and Judgements The preparation of Consolidated Financial Statements requires the use of accounting estimates which, by definition, will seldom equal the actual results. Management also needs to exercise judgement in applying the Group’s accounting policies. This note provides an overview of the areas that involved a higher degree of judgement or complexity, and of items which are more likely to be materially adjusted due to estimates and assumptions turning out to be different than those originally assessed. a Recognition and measurement of defined benefit obligations The obligation arising from defined benefit plan is determined on the basis of actuarial assumptions. Key actuarial assumptions include discount rate, trends in salary escalation and vested future benefits and life expectancy. The discount rate is determined by reference to market yields at the end of the reporting period on government bonds. The period to maturity of the underlying bonds correspond to the probable maturity of the post-employment benefit obligations. b Estimation of useful life Useful lives of tangible assets and intangible assets are based on the estimate by the management. The useful lives as estimated are same as prescribed in Schedule II of the Companies Act, 2013. In cases, where the useful lives are different from that prescribed in Schedule II, they are based on management estimate, taking into account the nature of the asset, the estimated usage of the asset, the operating conditions of the asset, past history of replacement, anticipated technological changes, manufacturers’ warranties and maintenance support. Assumptions also need to be made, when the Group assesses, whether an asset may be capitalized and which components of the cost of the asset may be capitalised. The useful lives and residual values of Group’s assets are determined by management at the time the asset is acquired and reviewed annually for appropriateness. The lives are based on historical experience with similar assets as well as anticipation of future events which may impact their life such as changes in technology. c Provisions and contingent liabilities The Group exercises judgement in measuring and recognising provisions and the exposures to contingent liabilities related to pending litigation or other outstanding claims subject to negotiated settlement, mediation, arbitration or government regulation, as well as other contingent liabilities. Judgement is necessary in assessing the likelihood that a pending claim will succeed, or a liability will arise, and to quantify the possible range of the financial settlement. Because of the inherent uncertainty in this evaluation process, actual losses may be different from the originally estimated provision. d Impairment of assets The Group reviews the carrying amounts of its property, plant and equipment, Capital work-in-progress and intangible assets, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If any such indication exists, the recoverable amount of the asset is estimated to determine the extent of the impairment loss (if any). Further details on the Group’s accounting policies on this are set out in the accounting policy above. Determining whether an asset is impaired requires an estimation of the recoverable amount, which requires group to estimate the Fair value less cost of disposal. The significant assumptions used by the Group in determining the impairment loss have been detailed in Note 3(b).
