The standalone financial statements have been prepared and presented on the going concern basis using accrual basis of accounting and under the historical cost convention except for following assets and liabilities which are measured at fair value:

• Derivative financial instruments; see Note 5F for accounting policy

• Certain financial assets and liabilities; see Note 5, 12, 18 and 35 for accounting policy

• Assets held for sale; see Note 9 for accounting policy

• Employee’s defined benefit plan assets and liabilities; see Note 14B(a) for accounting policy

• Liability for cash based share-based payments; see 14B(b) for accounting policy

• Inventories those are designated in a fair value hedge relationship; see Note 8A, 5F for accounting policy

• Assets and liabilities designated as hedged items in fair value hedges that would otherwise be carried at amortised cost are adjusted to record changes in the fair values attributable to the risks that are being hedged in effective hedge accounting; see Note 5F for accounting policy

In preparing the financial statements, transactions in currencies other than the Company’s functional currency (foreign currencies) are recognised at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are translated at the rates prevailing at that date. Non-monetary items are measured at historical cost.

Exchange differences on monetary items are recognised in the statement of profit and loss in the period in which they arise, except for:

• eligible exchange differences on foreign currency borrowings relating to qualifying assets under construction are included in the cost of those assets when they are regarded as an adjustment to interest costs; and

• exchange differences on transactions entered into in order to hedge certain foreign currency risks (see Note 5F for accounting policies).

Changes in the fair value of non-monetary equity instruments irrevocably classified as fair value through other comprehensive income includes gain or loss on account of exchange differences.

The fair value of financial liabilities and financial assets denominated in a foreign currency are translated at the spot rate at the end of the reporting period. The foreign exchange component forms part of its fair value gain or loss. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was measured.

The Company has determined current and non-current classification of its assets and liabilities in the standalone financial statements as per the Company’s normal operating cycle, and other criteria set out in Schedule III of the Companies Act, 2013. Based on the nature of products and the time lag between the acquisition of assets for processing and their realisation in cash and cash equivalents, the Company has ascertained its normal operating cycle as 12 months for the purpose of current and non-current classification of its assets and liabilities.

3A. Property, Plant and Equipment

Property, plant and equipment held for use in the production or/andsupply of goods or services, or foradministrative purposes are stated in the balance sheet at cost, less any subsequent accumulated depreciation and subsequent accumulated impairment losses except for freehold land (other than freehold land used for mining) which is carried at historical cost.

The present value of obligatory decommissioning cost related to assets are included in the initial cost of such assets. Cost may also include effective portion on qualifying cash flow hedges of foreign currency purchases of property, plant and equipment transferred from hedge reserve as basis adjustment.

Subsequent expenditure on major maintenance or repairs includes the cost of the replacement of parts of assets and overhaul costs. Where an asset or part of an asset is replaced and it is probable that future economic benefits associated with the item will be available to the Company, the expenditure is capitalised and the carrying amount of the item replaced is derecognised. Similarly, overhaul costs associated with major maintenance which can be measured reliably are capitalised and depreciated over their useful lives where it is probable that future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognised. AH other costs are charged to profit and loss during the reporting period in which they are incurred.

The Company based on the technical assessment made by the technical expert/management estimate, depreciates certain items of building, plant and equipment’s over the estimated useful lives which are different from the useful life prescribed in Schedule II to the Companies Act, 2013. The management believes that these estimated useful lives are realistic and reflect fair approximation of the period over which the assets are likely to be used.

The Company reviews the estimated residual values and expected useful lives of assets at least annually. In particular, the Company considers the impact of the health, safety and environmental legislation in its assessment of expected usefule lives and estimated residual values. Furthermore, the Company considers environment-related matters, including physical and transition risks. Specifically, the Company determines whether environment-related legislation and regulations might impact either the useful lives or residual values.Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets as follows:

^A Includes freehold land used for mining which is depreciated over 8 - 30 years.

$ Cost incurred subsequent to capitalisation, accounted as a separate component, is depreciated over the remaining useful life of the underlying

asset.

The accounting policy on depreciation and impairment of non-current assets are described in notes 3G and 3H, respectively.
