3 SIGNIFICANT ACCOUNTING POLICIES a Basis of Preparation
These standalone financial statements have been prepared on historical cost basis except for certain financial instruments and defined benefit plans which are measured at fair value or amortised cost at the end of each reporting period. Historical cost is generally based on the fair value of the consideration given in exchange for goods and services. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. All assets and liabilities have been classified as current and non-current as per the Company's normal operating cycle. Based on the nature of services rendered to customers and time elapsed between deployment of resources and the realisation in cash and cash equivalents of the consideration for such services rendered, the Company has considered an operating cycle of 12 months.
b Use of estimates
The preparation of standalone financial statements in conformity with the recognition and measurement principles of Ind AS requires management of the Company to make estimates and judgements that affect the reported balances of assets and liabilities, disclosures of contingent liabilities as at the date of standalone financial statements and the reported amounts of income and expenses for the periods presented.
Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimates are revised and future periods are affected.
The Company uses the following critical accounting estimates in preparation of its standalone financial statements.
(i) Useful lives of property, plant and equipment
The Company reviews the useful life of property, plant and equipment at the end of each reporting period. This reassessment may result in change in depreciation expense in future periods.
(ii) Fair value measurement of financial instruments
When the fair value of financial assets and financial liabilities recorded in the balance sheet cannot be measured based on quoted prices in active markets, their fair value is measured using valuation techniques including the Discounted Cash Flow model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgement is required in establishing fair values. Judgements include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments.
(iii) Provision for income tax and deferred tax assets
The Company uses estimates and judgements based on the relevant rulings in the areas of allocation of revenue, costs, allowances and disallowances which is exercised while determining the provision for income tax. A deferred tax asset is recognised to the extent that it is probable that future taxable profit will be available against which the deductible temporary differences and tax losses can be utilised. Accordingly, the Company exercises its judgement to reassess the carrying amount of deferred tax assets at the end of each reporting period.
