1. Significant Accounting Policies:

A. Accounting Convention

These financial statements are brpared in accordance with Indian Generally Accepted Accounting Principles (GAAP) under the historical cost convention on an accrual basis. GAAP comprises mandatory accounting standards as brscribed under Section 133 of the Companies Act, 2013 ('Act') read with Rule 7 of the Companies (Accounts) Rules, 2014, the provisions of the Act (to the extent notified) and guidelines issued by the Securities and Exchange Board of India (SEBI). All the assets and liabilities are classified as current or non-current as per the criteria set out in Schedule III to the Companies Act, 2013.

B. Use of Estimates

The brparation of financial statements require estimates and assumptions to be made that affect the reported amount of assets and liabilities on the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Difference between the actual results and estimates are recognized in the period in which the results are known/ materialized.

C. Fixed Assets

(a) Tangible Assets are stated at cost less accumulated debrciation and impairment loss, if any. Cost comprises of purchase price and any directly attributable cost of bringing the assets to its working condition for its intended use.

(b) Intangible Assets are stated at cost less accumulated amortization and impairment loss, if any. Cost includes any directly attributable expenditure on making the asset ready for its intended use.

(c) Machinery spares which can be used only in connection with an item of Tangible Asset and whose use is not of regular nature are written off over the estimated useful life of the relevant asset.

(d) Certain directly attributable br-operative expenses during construction period are included under Capital Work-in-Progress. These expenses are allocated to the cost of Fixed Assets when the same are ready for intended use.

D. Debrciation and Amortization

(a) Debrciation on Tangible Assets, except leasehold land, has been provided using Straight Line Method over the estimated useful life of the assets in a manner brscribed in Part C of Schedule II of the Companies Act, 2013. Leasehold lands are amortized over the period of lease on straight line basis.

(b) Intangible Assets, except Mining Rights, are amortized over their estimated useful lives on straight line basis. Mining Rights are amortized over the period of lease on straight line basis or on the basis of production, proportional to mineral resources expected to be ultimately economically recoverable, whichever is higher.

E. Impairment

An asset is treated as impaired when the carrying cost of the asset exceeds its recoverable value being higher of value in use and net selling price. Value in use is computed at net brsent value of cash flow expected over the balance useful life of the assets. An impairment loss is recognized as an expense in the Statement of

Profit and Loss in the year in which an asset is identified as impaired. The impairment loss recognized in prior accounting period is reversed if there has been an improvement in recoverable amount.

F. Leases

Lease payments under an operating lease are recognized as expense in the Statement of Profit and Loss as per terms of lease agreement.

G. Investments

(a) Long term investments are carried at cost after deducting provision, if any, for diminution in value considered to be other than temporary in nature.

(b) Current investments are stated at lower of cost and fair value.

H. Inventories

(a) Inventories of stores and spare parts are valued at or below cost after providing for cost of obsolescence and other anticipated losses, wherever considered necessary. Inventory of other items are valued 'at Cost or Net Realizable Value, whichever is lower'. Cost is generally determined on weighted average cost basis and wherever required, appropriate overheads are taken into account. Net Realizable Value is the estimated selling price in the ordinary course of business less the estimated cost of completion and the estimated costs necessary to make the sale. However, materials and other supplies held for use in the production of inventories are not written down below cost if the finished products in which they will be used are expected to be sold at or above cost.

(b) Fair value hedges are mainly used to hedge the exposure to change in fair value of commodity price risks. The fair value adjustment remains part of the carrying value of inventory and enters into the determination of earnings when the inventory is sold.

I. Foreign Currency Transactions

Transactions in foreign currency are recorded at the rate of exchange brvailing on the date of transaction. Year end balance of foreign currency monetary item is translated at the year end rates. Exchange differences arising on settlement of monetary items or on reporting of monetary items at rates different from those at which they were initially recorded during the period or reported in brvious financial statements are recognized as income or expense in the period in which they arise. Foreign currency monetary items those are used as hedge instruments or hedged items are accounted as per accounting policy on derivative financial instruments.

J. Employee benefits

Employee benefits of short term nature are recognized as expense as and when these accrue. Long term employee benefits and post employment benefits, whether funded or otherwise, are recognized as expense based on actuarial valuation at year end using the projected unit credit method. For discounting purpose, market yield of Government Bonds, at the balance sheet date, is used. Actuarial gains or losses are recognized immediately in the Statement of Profit and Loss.

K. Employee Share Based Payments

Equity settled stock options granted to employees pursuant to the Company's stock option schemes are accounted for as per the intrinsic value method brscribed by Employee Stock Option Scheme and permitted

by the SEBI guidelines, 1999 and the Guidance Note on Share Based Payment issued by the Institute of Chartered Accountants of India (ICAI). The intrinsic value of the option being excess of market value of the underlying share at the date of grant of option, over its exercise price is recognised as deferred employee compensation with a credit to Employees Stock Options Outstanding Account. The deferred employee compensation is amortized to Statement of Profit and Loss on straight line basis over the vesting period of the option. In case of forfeiture of option which is not vested, amortised portion is reversed by credit to employee compensation expense. In a situation where the stock option expires unexercised, the related balance standing to the credit of the employees Stock Options Outstanding Account are transferred to the General Reserve.

L. Revenue Recognition

Sales revenue is recognized on transfer of significant risk and rewards of the ownership of the goods to the buyer and stated at net of trade discount and rebates. Dividend income on investments is accounted for when the right to receive the payment is established. Export incentive, certain insurance, railway and other claims where quantum of accruals cannot be ascertained with reasonable certainty, are accounted on acceptance basis.

M. Borrowing Costs

Borrowing costs directly attributable to the acquisition or construction of qualifying assets are capitalized. Other borrowing costs are recognized as expenses in the period in which they are incurred. In determining the amount of borrowing costs eligible for capitalization during a period, any income earned on the temporary investment of those borrowings is deducted from the borrowing costs incurred.

N. Taxation

(a) Provision for current income tax is made in accordance with the Income tax Act, 1961. Deferred tax assets and deferred tax liabilities are recognized at substantively enacted tax rates, subject to the consideration of prudence, on timing difference, being the difference between taxable income and accounting income that originate in one period and are capable of reversal in one or more subsequent periods.

(b) Minimum Alternative Tax (MAT) is recognized as an asset only when and to the extent there is convincing evidence that the Company will pay normal Income Tax during the specified period. In the year in which the MAT credit becomes eligible to be recognized as an asset in accordance with the recommendations contained in guidance note issued by the ICAI, the said asset is created by way of credit to Statement of Profit and Loss and shown as MAT credit entitlement. The Company reviews the same at each Balance Sheet date and writes down the carrying amount of MAT entitlement to the extent there is no longer convincing evidence to the effect that Company will pay normal Income Tax during the specified period.

O. Derivative Financial Instruments

(a) The Company uses derivative financial instruments such as Forwards, Swaps, Options, futures etc. to hedge its risks associated with foreign exchange fluctuations. Risks associated with fluctuations in the price of the products (e.g. Copper, Alumina, Aluminium, Coal and brcious metals) are minimized by undertaking hedging using appropriate derivative instruments. Derivatives embedded in other financial instruments or other host contracts are treated as separate derivatives when their risks and characteristics are not closely related to their host contracts. In some cases, the embedded derivatives may be designated in a hedge relationship. The fair values of all such derivative financial instruments are recognized as assets or liabilities at the balance sheet date. All such derivative financial instruments are used as risk management tools only and not for speculative purposes.

(b) For derivative financial instruments and foreign currency monetary items designated as Cash Flow hedges, the effective portion of the fair value of the hedge instruments are recognized in Hedging Reserve and reclassified to 'Revenue from Operations', 'Cost of Materials Consumed' or 'Other Expenses' in the period in which the Statement of Profit and Loss is impacted by the hedged items or in the period when the hedge relationship no longer qualifies as cash flow hedge. In cases where the exposure gives rise to a non-financial asset, the effective portion is reclassified from Hedging Reserve to the initial carrying amount of the non-financial asset as a 'basis adjustment' and recycled to the Statement of Profit and Loss when and the manner in which the respective non- financial asset affects the Statement of Profit and Loss in future periods. The ineffective portion of the change in fair value of such instruments is recognized in the Statement of Profit and Loss in the period in which they arise. If the hedging relationship ceases to be effective or it becomes probable that the expected forecast transaction will no longer occur, hedge accounting is discontinued and the fair value changes arising from the derivative financial instruments are recognized in 'Other Expenses' in the Statement of Profit and Loss.

(c) For derivative financial instruments designated as Fair Value hedges, the fair value of both the derivative financial instrument and the hedged item are recognized in 'Revenue from Operations', 'Cost of Materials Consumed' or 'Other Expenses' in the Statement of Profit and Loss till the period the relationship is found to be effective. If the hedging relationship ceases to be effective or it becomes probable that the expected transaction will no longer occur, future gains or losses on the derivative financial instruments are recognized in 'Other Expenses' in the Statement of Profit and Loss.

(d) If no hedging relationship is designated, the fair value of the derivative financial instruments is marked to market through Statement of Profit and Loss and included in 'Other Expenses'.

P. Research and Development

Expenditure incurred during research and development phase is charged to revenue when no intangible asset arises from such research. Assets procured for research and development activities are generally capitalized.

Q. Government Grants

Government Grants are recognized when there is a reasonable assurance that the same will be received. Revenue grants are recognized in the Statement of Profit and Loss. Capital grants relating to specific fixed assets are reduced from the gross value of the respective fixed assets. Other capital grants are credited to Capital Reserve.

R. Provisions, Contingent Liabilities and Contingent Assets

Provision is recognized when there is a brsent obligation as a result of a past event that probably requires an outflow of resources and a reliable estimate can be made of the amount of the obligation. Disclosure for contingent liability is made when there is a possible obligation or a brsent obligation that may, but probably will not, require an outflow of resources. No provision is recognized or disclosure for contingent liability is made when there is a possible obligation or a brsent obligation and the likelihood of outflow of resources is remote. Contingent Asset is neither recognized nor disclosed in the financial statements
