2. BASIS OF PREPARATION OF FINANCIAL STATEMENTS

Basis of preparation

The financial statements of the Company have been prepared in accordance with Indian Accounting Standards (Ind AS) notified under the Companies (Indian Accounting Standards) Rules, 2015 (as amended from time to time) and presentation requirement of Division II of schedule III to the Companies Act, 2013 (Ind AS compliant Schedule III), as applicable. The financial statements have been prepared on a going concern basis using historical cost convention and on the accrual basis except for financial instruments which are measured at fair values (refer note 3(I)(a) below). The Ind AS are prescribed under Section 133 of the Act read with Rule 3 of the Companies (Indian Accounting Standards) Rules, 2015, as amended.

Accounting policies have been consistently applied in all material aspects except where a newly issued accounting standard is initially adopted or a revision to an existing accounting standard requires a change in the accounting policy hitherto in use.

The financial statements are approved for issue by the Board of Directors on April 21, 2023. The revision to these financial statements is permitted by the Board of Directors after obtaining necessary approvals or at the instance of regulatory authorities as per provisions of the Act.

3.(I) SIGNIFICANT ACCOUNTING POLICIES

a) Fair value measurement

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

• In the principal market for the asset or liability, or

• In the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant''s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset

or liability and the level of the fair value hierarchy as explained above.

b) Current and non-current classification

The Company presents assets and liabilities in the balance sheet based on current/ non-current classification.

An asset is treated as current when it is:

• Expected to be realized or intended to be sold or consumed in normal operating cycle

• Held primarily for the purpose of trading

• Expected to be realized within twelve months after the reporting period, or

• Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period

All other assets are classified as non-current.

A liability is current when:

• It is expected to be settled in normal operating cycle

• It is held primarily for the purpose of trading

• It is due to be settled within twelve months after the reporting period, or

• There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as noncurrent assets and liabilities.

The operating cycle is the time between the acquisition of assets for processing and their realisation in cash and cash equivalents. The Company has identified twelve months as its operating cycle.

c) Functional and presentation currency

The financial statements are prepared in Indian Rupees (''), which is the Company''s functional currency. All financial information presented in Indian Rupees (?) has been rounded to the nearest crores. Amounts less than '' 0.50 Crore have been presented as “0”.

d) Revenue recognition

(i) Sale of goods (products, scrap and residual)

Revenue from contracts with customers is recognised when control (as defined in Ind AS 115) of the goods or services is transferred to the customer as per the

terms of contract, which usually is on delivery of the goods to the carriers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue is recognised net of discounts, volume rebates, outgoing sales taxes/ goods and service tax and other indirect taxes. Revenues from sale of by-products are included in revenue.

Certain of the Company''s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME), as specified in the contract. Revenue in respect of such contracts is recognised when control passes to the customer and is measured at the amount the entity expects to be entitled - being the estimate of the price expected to be received at the end of the measurement period. Post transfer of control of goods, provisional pricing features are accounted in accordance with Ind AS 109 ‘Financial Instruments'' rather than Ind AS 115 and therefore the Ind AS 115 rules on variable consideration do not apply. These ‘provisional pricing'' adjustments i.e. the consideration received post transfer of control are included in total revenue from operations on the face of the Statement of Profit and loss. Final settlement of the price is based on the applicable price for a specified future period. The Company''s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue.

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration when that right is conditional on Company''s future performance.

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company transfers goods or services to the customer, a contract liability is recognised when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Company performs under the contract.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and

payment by the customer exceeds one year. As a consequence, the Company does not adjust any of the transaction prices for the time value of money.

(ii) Income from wind energy

Revenue from sale of wind power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognized in the Statement of Profit and Loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, with reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset''s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists.

e) Property, plant and equipment

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and non-refundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended use. Plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. The present value of the expected cost for the decommissioning of an asset and mine restoration after its use is included

in the cost of the respective asset if the recognition criteria for a provision are met. Major machinery spares and parts are capitalized when they meet the definition of Property, Plant and Equipment. Expenditure incurred after the property, plant and equipment have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/ other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profit and Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading “Mining properties” in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will provide sufficient and sustainable return relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

(v) Exploration & evaluation assets

Exploration and evaluation expenditure incurred prior to obtaining the mining right or the legal right to explore are expensed as incurred.

Exploration and evaluation expenditure incurred after obtaining the mining right or the legal right to explore, are capitalised as exploration and evaluation assets (intangible assets) and stated at cost less impairment, if any. Exploration and evaluation assets are transferred to the appropriate category of property, plant and equipment when the technical feasibility and commercial viability has been determined. Exploration and evaluation assets are assessed for impairment and impairment loss, if any, is recognised prior to reclassification.

Exploration expenditure includes all direct and allocated indirect expenditure associated with finding specific Mineral Resources.

(vi) Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the asset. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consists of interest and other costs that an entity incurs in connection with the borrowings of the funds.

f) Intangible assets

I ntangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated


(iii) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property, plant and equipment. Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on the straight-line method.

• Depreciation has been provided over remaining useful life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

• Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining commercial Ore Reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off. Costs used in the computation of unit of production comprises the net book value of the capitalised costs plus the future estimated costs required to be incurred to access the commercial reserves.

• Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life. Amounts paid for securing mining rights are amortized over the period of mining lease of 20 years. The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to reflect the changed pattern, if any.

Intangible assets with indefinite useful lives are not amortised, but are tested for impairment annually, either individually or at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis.

An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the Statement of Profit and Loss when the asset is derecognised.

g) Impairment of non-financial assets

I mpairment charges and reversals are assessed at the level of cash-generating units. A cash-generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

I mpairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

I f any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset''s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants and does not reflect the effects of factors that may be specific to the entity and not applicable to entities in general.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company''s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset''s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

h) Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition and subsequent measurement

The classification of financial assets at initial recognition depends on the financial asset''s contractual cash flow characteristics and the Company''s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient, financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition

of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Trade receivables that do not contain a significant financing component are measured at transaction price as per Ind AS 115. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

• Financial assets at amortized cost

A ‘financial asset'' is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

• Financial assets at fair value through other comprehensive income (FVTOCI)

A ‘financial asset'' is classified as the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset''s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst

holding FVTOCI debt instrument is reported as interest income using the EIR method.

For equity instruments, the Company may make an irrevocable election to present subsequent changes in the fair value in OCI. If the Company decides to classify an equity instrument as at FVTOCI, then all fair value changes on the instrument, excluding dividends, are recognized in the OCI. There is no recycling of the amounts from OCI to the Statement of Profit and Loss, even on sale of investment. However, the Company may transfer the cumulative gain or loss within equity.

• Financial assets at fair value through Statement of Profit and Loss (FVTPL)

FVTPL is a residual category for debt instruments and default category for equity instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (referred to as ‘accounting mismatch''). The Company has not invested in any equity instruments.

Debt instrument included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss. For equity instruments which are classified as FVTPL, all subsequent fair value changes are recognised in the Statement of Profit and Loss.

Further, the provisionally priced trade receivables are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company''s balance sheet) when:

• The rights to receive cash flows from the asset have expired, or

• The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘passthrough'' arrangement; and either (a) the Company has transferred substantially all the risks and rewards of

the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a passthrough arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company''s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets

I n accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

• Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

• Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ‘simplified approach'' for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion

of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/ expense in the Statement of Profit and Loss (P&L). This amount is reflected under the head ‘other expenses'' in the Statement of Profit and Loss (P&L). The balance sheet presentation for various financial instruments is described below:

• Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

• Debt instruments measured at FVTOCI: Since financial assets are already reflected at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ‘accumulated impairment amount'' in the OCI.

For assessing increase in credit risk and impairment loss, the Company combines financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and subsequent measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company''s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

The measurement of financial liabilities depends on their classification, as described below:

• Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the Statement of Profit and Loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss.

• Financial Liabilities at amortized cost (Loans, Borrowings and Trade and Other payables)

After initial recognition, interest-bearing loans, borrowings and Trade and Other payables are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a nonderivative host contract - with the effect that some of the cash flows of the combined instrument vary in a way similar to a standalone derivative. An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a non-financial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

I f the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does not separate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value through Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the Company''s operations. Such changes are evident to external parties. A change in the business model occurs when the Company either begins or ceases to perform an activity that is significant to its operations. If the Company reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

i) Derivative financial instruments and hedge accounting

Initial recognition and subsequent measurement

In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

• Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

• Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge. The documentation includes the Company''s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature

of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument''s fair value in offsetting the exposure to changes in the hedged item''s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the Statement of Profit and Loss.

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity

until the forecast transaction occurs or the foreign currency firm commitment is met.

j) Government grants, subsidies and export incentives

Grants and subsidies from the government are recognized when there is reasonable assurance that (i) the Company will comply with the conditions attached to them, and (ii) the grant/ subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit and Loss over the periods necessary to match them with the related costs, which they are intended to compensate.

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asset and presented within other income.

When the Company receives grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual installments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favourable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

k) Inventories

Inventories are valued at the lower of cost and net realizable value, less any provision for obsolescence.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-in-progress and finished goods (including significant byproducts i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) I mmaterial by-products, aluminium scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

l) Taxation

Current tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

• When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

• In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

• When the deferred tax asset relating to the deductible temporary difference arises from the initial

recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

• In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognised outside profit or loss is recognised outside profit or loss (either in other comprehensive income or in equity). Deferred tax items are recognised in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

m) Retirement and other employee benefit schemes

i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized as an expense as the related service is rendered by employees.

ii. Post-employment benefits Gratuity

I n accordance with the Payment of Gratuity Act of 1972, the Company contributes to a defined benefit plan (the “Gratuity Plan”). The Gratuity Plan provides a lump sum payment to employees who have completed at least 5 years of service; at retirement, disability or termination of employment being an amount equal to 15 days'' salary (based on the respective employee''s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

I n respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Remeasurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

• Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

• Net interest expense or income Provident fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ‘Hindustan Zinc Limited Employee''s Contributory Provident Fund'' (the ‘Trust'') accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any,

between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family pension scheme. Contributions are paid during the year into the fund under statutory arrangements. The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss. The Company has no further obligation other than the contribution made.

Superannuation

Certain employees of the Company, who have joined post disinvestment are members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term employee benefits

Compensated absences

The Company has a policy on compensated absences which are both accumulating and nonaccumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid / availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on non-accumulating compensated absences is recognized in the period in which the absences occur. Actuarial differences are recognised immediately in the Statement of Profit and Loss.

n) Provision

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the

risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate.

(i) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that reflects the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of Profit and Loss. Management estimates are based on third party technical estimates. The actual costs and cash outflows may differ from estimates because of changes in laws and regulations, changes in prices, analysis of site conditions and changes in restoration technology. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate.

(ii) Provision for restoration, rehabilitation and environmental costs

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or ongoing production of a mine. Such costs, discounted to net present value, are provided for and a c

2. BASIS OF PREPARATION OF FINANCIAL STATEMENTS

a) Basis of preparation

The financial statements of the company have been prepared in accordance with Indian Accounting Standards (Ind AS) notified under the Companies (Indian Accounting Standards) Rules, 2015 (as amended from time to time) and presentation requirement of Division II of schedule III to the Companies Act, 2013 (Ind AS compliant Schedule III), as applicable. The financial statements have been prepared on a historical cost convention on the accrual basis except for financial instruments which are measured at fair values (Refer note 3(a) below) and the provisions of the Companies Act, 2013 (''Act'') (to the extent notified). The Ind AS are prescribed under Section 133 of the Act read with Rule 3 of the Companies (Indian Accounting Standards) Rules, 2015, as amended.

Accounting policies have been consistently applied in all material aspects except where a newly issued accounting standard is initially adopted or a revision to an existing accounting standard requires a change in the accounting policy hitherto in use.

The financial statements were authorised for issue in accordance with a resolution of Board of Directors on April 22, 2022.

b) Reclassification

Consequent to amendments to the Schedule III to the Companies Act, 2013, current maturities of longterm borrowings (March 2021: ''704 Crore) have been presented as part of the short term borrowings, which were previously included under ‘other financial liabilities’, lease liabilities (March 2021: ''24 Crore) have been presented on the face of balance sheet,

which were previously included under ‘other financial liabilities’ and Security deposits (March 2021: ''11 Crore) have been presented as part of other non current financial asset, which were previously included under ‘loans’ in non current financial assets.

3.(I) SIGNIFICANT ACCOUNTING POLICIES

a) Fair value measurement

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

• In the principal market for the asset or liability, or

• I n the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant''s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the

basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

b) Current and non-current classification

The Company presents assets and liabilities in the balance sheet based on current/ non-current classification.

An asset is treated as current when it is:

• Expected to be realized or intended to be sold or consumed in normal operating cycle

• Held primarily for the purpose of trading

• Expected to be realized within twelve months after the reporting period, or

• Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period

All other assets are classified as non-current.

A liability is current when:

• It is expected to be settled in normal operating cycle

• It is held primarily for the purpose of trading

• It is due to be settled within twelve months after the reporting period, or

• There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as noncurrent.

Deferred tax assets and liabilities are classified as noncurrent assets and liabilities.

The operating cycle is the time between the acquisition of assets for processing and their realisation in cash and cash equivalents. The Company has identified twelve months as its operating cycle.

c) Functional and presentation currency

The financial statements are prepared in Indian Rupees (INR), which is the Company’s functional currency. All financial information presented in INR has been rounded to the nearest crores.

d) Revenue recognition

(i) Sale of goods (Products, Scrap and residual)

Revenue from contracts with customers is recognised when control of the goods or services is transferred to the customer which usually is on delivery of the goods to the carriers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue is recognised net of discounts, volume rebates, outgoing sales

taxes/ goods and service tax and other indirect taxes. Revenues from sale of by-products are included in revenue.

Certain of the Company''s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME), as specified in the contract. Revenue in respect of such contracts is recognised when control passes to the customer and is measured at the amount the entity expects to be entitled - being the estimate of the price expected to be received at the end of the measurement period. Post transfer of control of goods, provisional pricing features are accounted in accordance with Ind AS 109 ‘Financial Instruments’ rather than Ind AS 115 and therefore the Ind AS 115 rules on variable consideration do not apply. These ‘provisional pricing’ adjustments i.e. the consideration received post transfer of control are included in total revenue from operations on the face of the Statement of Profit and loss. Final settlement of the price is based on the applicable price for a specified future period. The Company’s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue.

Revenue from freight and insurance services is recognised over the period during which services are rendered.

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration when that right is conditional on Company''s future performance.

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company transfers goods or services to the customer, a contract liability is recognised when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Company performs under the contract.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, the Company does not adjust any of the transaction prices for the time value of money.

(ii) Income from wind energy

Revenue from sale of wind power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognized in the statement of profit and loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, with reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset''s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists.

e) Property, plant and equipment

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and non-refundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended use. Plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. The present value of the expected cost for the decommissioning of an asset and mine restoration after its use is included in the cost of the respective asset if the recognition criteria for a provision are met. Major machinery spares and parts are capitalized when they meet the definition of Property, Plant and Equipment. Expenditure incurred after the property, plant and equipment

have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profit and Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading “Mining properties” in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will provide sufficient and sustainable return relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated.

(iii) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property, plant and equipment. Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on the straight-line method.

• Depreciation has been provided over remaining useful life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

• Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining commercial ore reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off. Costs used in the computation of unit of production comprises the net book value of the capitalised costs plus the future estimated costs required to be incurred to access the commercial reserves.

• Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

Assets

Useful life in years

Factory buildings

30 years

Residential buildings

60 years

Roads (included in buildings)

5-10 years

Computers and data processing equipment (included in office equipments)

3-6 years

Plant and Equipment (Including captive power plant)

8-40 years

Railway sidings

15 years

Office equipment

5 years

Furniture and fixtures

10 years

Vehicles

8-10 years

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

(v) Exploration & evaluation assets

Exploration and evaluation expenditure incurred prior to obtaining the mining right or the legal right to explore are expensed as incurred.

Exploration and evaluation expenditure incurred after obtaining the mining right or the legal right to explore, are capitalised as exploration and evaluation assets (intangible assets) and stated at cost less impairment, if any. Exploration and evaluation assets are transferred to the appropriate category of property, plant and equipment when the technical feasibility and commercial viability has been determined. Exploration and evaluation assets are assessed for impairment and impairment loss, if any, is recognised prior to reclassification.

Exploration expenditure includes all direct and allocated indirect expenditure associated with finding specific mineral resources.

(vi) Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the asset. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consists of interest and other costs that an entity incurs in connection with the borrowings of the funds.

f) Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life. Amounts paid for securing mining rights are amortized over the period of mining lease of 20 years. The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to reflect the changed pattern, if any.

Intangible assets with indefinite useful lives are not amortised, but are tested for impairment annually,

either individually or at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis.

An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the Statement of profit and loss when the asset is derecognised.

g) Impairment of non-financial assets

Impairment charges and reversals are assessed at the level of cash-generating units. A cash-generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

Impairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

If any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset''s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants and does not reflect the effects of factors that may be specific to the entity and not applicable to entities in general. Fair value for mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. These cash flows are discounted at an appropriate post tax discount rate to arrive at the net present value.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of

future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company’s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset''s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

h) Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition

All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

• Debt instruments at amortized cost

A ‘Debt instrument’ is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

• Debt instruments at fair value through other comprehensive income (FVTOCI)

A ‘debt instrument’ is classified as at the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset’s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method.

• Debt instruments, derivatives and equity instruments at fair value through Statement of Profit and Loss (FVTPL)

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (Referred to as ''accounting mismatch'').The Company has not invested in any equity instruments.

Debt instrument included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company''s balance sheet) when:

• The rights to receive cash flows from the asset have expired, or

• The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a passthrough arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets

In accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

• Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

• Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ‘simplified approach’ for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such

that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/ expense in the Statement of Profit and Loss (P&L). This amount is reflected under the head ‘other expenses’ in the Statement of Profit and Loss (P&L). The balance sheet presentation for various financial instruments is described below:

• Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

• Debt instruments measured at FVTOCI: Since financial assets are already reflected at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ‘accumulated impairment amount’ in the OCI.

For assessing increase in credit risk and impairment loss, the Company combines financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and measurement Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

• Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the Statement of Profit and Loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss.

• Financial Liabilities at amortized cost (Loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated

as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a nonderivative host contract - with the effect that some of the cash flows of the combined instrument vary in a way similar to a stand-alone derivative. An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a nonfinancial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

If the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does not separate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets

The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the Company’s operations. Such changes are evident to external parties. A change in the business model occurs when the Company either begins or ceases to perform an activity that is significant to its operations. If the Company reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

i) Derivative financial instruments and hedge accounting

Initial recognition and subsequent measurement In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

• Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

• Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes the Company’s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument’s fair value in offsetting the exposure to changes in the hedged item’s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the Statement of Profit and Loss.

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met.

j) Government grants, subsidies and export incentives

Grants and subsidies from the government are recognized when there is reasonable assurance that (i) the Company will comply with the conditions attached to them, and (ii) the grant/subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit and Loss over the periods necessary to match them with the related costs, which they are intended to compensate.

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asset and presented within other income.

When the Company receives grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual instalments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favourable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

k) Inventories

Inventories are valued at the lower of cost and net realizable value, less any provision for obsolescence.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-in-progress and finished goods (including significant byproducts i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) Immaterial by-products, aluminium scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

l) Taxation Current tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

• When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

• In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

• When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

• In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognised outside profit or loss is recognised outside profit or loss (either in other comprehensive income or in equity). Deferred tax items are recognised in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

m) Retirement and other Employee benefit schemes

i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized as an expense as the related service is rendered by employees.

ii. Post-Employment Benefits Gratuity

I n accordance with the Payment of Gratuity Act of 1972, the Company contributes to a defined benefit plan (the “Gratuity Plan”). The Gratuity Plan provides a lump sum payment to employees who have completed at least 5 years of service; at

retirement, disability or termination of employment being an amount equal to 15 days'' salary (based on the respective employee’s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

In respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Re-measurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

• Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

• Net interest expense or income Provident Fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ‘Hindustan Zinc Limited Employee’s Contributory Provident Fund'' (''Trust'') accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any, between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family

pension scheme. Contributions are paid during the year into the fund under statutory arrangements. The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss. The Company has no further obligation other than the contribution made.

Superannuation

Certain employees of the Company, who have joined post disinvestment are members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term Employee Benefits Compensated absences

The Company has a policy on compensated absences which are both accumulating and non-accumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid/availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on non-accumulating compensated absences is recognized in the period in which the absences occur. Actuarial differences are recognised immediately in the Statement of Profit and Loss.

n) Provision

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate.

(i) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at

the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that reflects the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of profit and loss. Management estimates are based on third party technical estimates. The actual costs and cash outflows may differ from estimates because of changes in laws and regulations, changes in prices, analysis of site conditions and changes in restoration technology. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate.

(ii) Provision for Restoration, rehabilitation and environmental costs

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or on-going production of a mine. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalized at the start of each project as mining properties, as soon as the obligation to incur such costs arises. These costs are charged to the Statement of Profit and Loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision (considered as finance cost). The cost of the related asset is adjusted for changes in the provision due to factors such as updated cost estimates, changes to lives of operations, new disturbance and revisions to discount rates. The adjusted cost of the asset is depreciated prospectively over the lives of the assets to which they relate as per the depre

2. BASIS OF PREPARATION OF FINANCIAL STATEMENTS

a) Basis of preparation

The financial statements of the company have been prepared in accordance with Indian Accounting Standards (Ind AS) notified under the Companies (Indian Accounting Standards) Rules 2015 (as amended from time to time) and presentation requirement of Division II of schedule III to the Companies Act 2013 (Ind AS compliant Schedule III), as applicable. The financial statements have been prepared on a historical cost convention on the accrual basis except for financial instruments which are measured at fair values (Refer note 3(a) below) and the provisions of the Companies Act, 2013 (''Act'') (to the extent notified). The Ind AS are prescribed under Section 133 of the Act read with Rule 3 of the Companies (Indian Accounting Standards) Rules, 2015, as amended.

Accounting policies have been consistently applied in all material aspects except where a newly issued accounting standard is initially adopted or a revision to an existing accounting standard requires a change in the accounting policy hitherto in use.

The financial statements were authorised for issue in accordance with a resolution of Board of Directors on April 27, 2021.

b) Reclassification

i. The Company has revised the constituents of cash and cash equivalents for the purpose of cash flow statement to not consider the Earmarked unpaid dividend accounts hitherto included in other bank balance, as this is more appropriate. As a result of this change, earmarked unpaid dividend accounts amounting to '' 21 crore and '' 20 crore as at March 31, 2019 and March 31 , 2020 respectively will not form part of opening and closing cash and cash equivalents in the statement of Cash Flow for the year ended March 31,2020.

ii. The Company from the current year has decided to present liabilities with respect to operational buyer''s/suppliers credit (refer note 19) on the face of the balance sheet, which were previously included under trade payables to enhance the understanding of the financial statements. The value of such liabilities as at April 1,2019 was nil and this reclassification has not had any material impact on the financial statements.

3.(I) significant accounting policies a) Fair value measurement

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

• In the principal market for the asset or liability, or

• I n the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant''s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

b) Current and non-current classification

The Company presents assets and liabilities in the balance sheet based on current/ noncurrent classification.

An asset is treated as current when it is:

• Expected to be realized or intended to be sold or consumed in normal operating cycle

• Held primarily for the purpose of trading

• Expected to be realized within twelve months after the reporting period, or

• Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period

All other assets are classified as non-current.

A liability is current when:

• It is expected to be settled in normal operating cycle

• It is held primarily for the purpose of trading

• It is due to be settled within twelve months after the reporting period, or

• There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

The operating cycle is the time between the acquisition of assets for processing and their realisation in cash and cash equivalents. The Company has identified twelve months as its operating cycle.

c) Functional and presentation currency

The financial statements are prepared in Indian Rupees (INR), which is the Company''s functional currency. All financial information presented in INR has been rounded to the nearest crores.

d) Revenue recognition

(i) Sale of goods

Revenue from contracts with customers is recognised when control of the goods or services is transferred to the customer which usually is on delivery of the goods to the carriers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue is recognised net of discounts, volume rebates, outgoing sales taxes/ goods and service tax and other indirect taxes. Revenues from sale of by-products are included in revenue.

Certain of the Company''s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME), as specified in the contract. Revenue in respect of such contracts is recognised when control passes to the customer and is measured at the amount the entity expects to be entitled - being the estimate of the

price expected to be received at the end of the measurement period. Post transfer of control of goods, provisional pricing features are accounted in accordance with Ind AS 109 ''Financial Instruments'' rather than Ind AS 115 and therefore the Ind AS 115 rules on variable consideration do not apply. These ''provisional pricing'' adjustments i.e. the consideration received post transfer of control are included in total revenue from operations on the face of the Statement of Profit and loss. Final settlement of the price is based on the applicable price for a specified future period. The Company''s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue.

Revenue from freight and insurance services is recognised over the period during which services are rendered.

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration when that right is conditional on Company''s future performance.

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company transfers goods or services to the customer, a contract liability is recognised when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Company performs under the contract.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, the Company does not adjust any of the transaction prices for the time value of money.

(ii) Sale of wind energy

Revenue from sale of wind power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognized in the statement of profit and loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, with reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset''s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists.

e) Property, plant and equipment

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and nonrefundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended use. Plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. The present value of the

expected cost for the decommissioning of an asset and mine restoration after its use is included in the cost of the respective asset if the recognition criteria for a provision are met. Major machinery spares and parts are capitalized when they meet the definition of Property, Plant and Equipment. Expenditure incurred after the property, plant and equipment have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/ other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profit and Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading "Mining properties” in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will

ci iffiiorvh anrl ci ic oirmhJci mfi i rn

relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated. With respect to open pit operations, waste removal costs that are incurred in the open pit operations during the operational phase of these mines which provide improved access are recognized as assets. The cost of normal on-going operational stripping activities are recognized in the Statement of Profit and Loss as and when incurred.

When the benefit from the stripping costs are realized in the current period, the stripping costs are accounted as charge in statement of profit and loss account in deferred mining expenses head. Deferred stripping cost are included in mining properties within Property, Plant and Equipment and disclosed as a part of Mining properties. After initial recognition, the stripping activity asset is depreciated on a unit of production method over the expected useful life of the identified component of the ore body to which it improves access.

(iii) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property, plant and equipment. Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on

• Depreciation has been provided over remaining useful life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

• Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining commercial ore reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off. Costs used in the computation of unit of production comprises the net book value of the capitalised costs plus the future estimated costs required to be incurred to access the commercial reserves.

• Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

Assets

useful life in years

Factory buildings

30 years

Residential buildings

60 years

Roads (included in buildings)

5-10 years

Computers and data processing equipment

3-6 years

Plant and Equipment (Including

captive power plant)

8-40 years

Railway sidings

15 years

Office equipment

5 years

Furniture and fixtures

10 years

Vehicles

8-10 years

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

(v) Exploration & evaluation assets:

Exploration and evaluation expenditure incurred prior to obtaining the mining right or the legal right to explore are expensed as incurred.

Exploration and evaluation expenditure incurred after obtaining the mining right or the legal right to explore, are capitalised as exploration and evaluation assets (intangible assets) and stated at cost less impairment, if any. Exploration and evaluation assets are transferred to the appropriate category of property, plant and equipment when the technical feasibility and commercial viability has been determined. Exploration and evaluation assets are assessed for impairment and impairment loss, if any, is recognised prior to reclassification.

Exploration expenditure includes all direct and allocated indirect expenditure associated with finding specific mineral resources.

vi) Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the asset. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consists of interest and other costs that an entity incurs in connection with the borrowings of the funds.

f) intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life. Amounts paid for securing mining rights are amortized over the period of mining lease of 20 years. The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to reflect the changed pattern, if any.

Intangible assets with indefinite useful lives are not amortised, but are tested for impairment annually, either individually or at the cashgenerating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable. If not, the change in useful life from indefinite to finite is made on a prospective basis.

An intangible asset is derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the Statement of profit and loss when the asset is derecognised.

g) impairment of non-financial assets

Impairment charges and reversals are assessed at the level of cash-generating units. A cashgenerating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

Impairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

If any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset''s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly

transaction between market participants and does not reflect the effects of factors that may be specific to the entity and not applicable to entities in general. Fair value for mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. These cash flows are discounted at an appropriate post tax discount rate to arrive at the net present value.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company''s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset''s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

h) Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition

All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

• Debt instruments at amortized cost

A ''Debt instrument'' is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

• Debt instruments at fair value through other comprehensive income (FVTOCI)

A ''debt instrument'' is classified as at the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset''s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method.

Debt instruments, derivatives and equity instruments at fair value through Statement of Profit or Loss (FVTPL)

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (Referred to as ''accounting mismatch j.The Company has not invested in any equity instruments.

Debt instrument included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company''s balance sheet) when:

• The rights to receive cash flows from the asset have expired, or

• The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ''passthrough'' arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company''s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

impairment of financial assets

In accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

• Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

• Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ''simplified approach'' for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/ expense in the Statement of Profit and Loss (P&L). This amount is reflected under the head ''other expenses'' in the Statement of Profit and Loss (P&L). The balance sheet presentation for various financial instruments is described below:

• Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

• Debt instruments measured at FVTOCI: Since financial assets are already reflected

at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ''accumulated impairment amount'' in the OCI.

For assessing increase in credit risk and impairment loss, the Company combines financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company''s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

• Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the Statement of Profit or Loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss.

• Financial Liabilities at amortized cost (Loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a non-derivative host contract - with the effect

that some of the cash flows of the combined instrument vary in a way similar to a stand-alone derivative. An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a non-financial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

If the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does not separate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets

The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the Company''s operations. Such changes are evident to external parties. A change in the business model occurs when the Company either begins or ceases to perform an activity that is significant to its operations. If the Company reclassifies financial assets, it applies

the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

i) Derivative financial instruments and hedge accounting

initial recognition and subsequent measurement

In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or nonfinancial liability.

For the purpose of hedge accounting, hedges are classified as:

• Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met.

j) Government grants, subsidies and export incentives

Grants and subsidies from the government are recognized when there is reasonable assurance that (i) the Company will comply with the conditions attached to them, and (ii) the grant/ subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit a nd Loss over the periods necessary to match them with the related costs, which they are intended to compensate.

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asset and presented within other income.

When the Company receives grants of nonmonetary assets, the asset and the grant are recorded at fair value amounts and released

• Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge. The documentation includes the Company''s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument''s fair value in offsetting the exposure to changes in the hedged item''s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the Statement of Profit and Loss.

to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual instalments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favourable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

k) inventories

Inventories are valued at the lower of cost and net realizable value, less any provision for obsolescence.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-inprogress and finished goods (including significant by-products i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) Immaterial by-products, aluminium scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

l) Taxation Current tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit

or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

• When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and , at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

• In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

• When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and , at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

• In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognised outside profit or loss is recognised outside profit or loss (either in other comprehensive income or in equity). Deferred tax items are recognised in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

m) Retirement and other Employee benefit schemes

i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized

as an expense as the related service is rendered by employees.

ii. Post-Employment Benefits Gratuity

In accordance with the Payment of Gratuity Act of 1972, the Company contributes to a defined benefit plan (the "Gratuity Plan”). The Gratuity Plan provides a lump sum payment to employees who have completed at least 5 years of service; at retirement, disability or termination of employment being an amount equal to 15 days'' salary (based on the respective employee''s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

In respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Re-measurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

• Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

• Net interest expense or income

Provident Fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ''Hindustan Zinc Limited Employee''s Contributory Provident Fund'' (''Trust'') accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any, between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family pension scheme. Contributions are paid during the year into the fund under statutory arrangements. The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss. The Company has no further obligation other than the contribution made.

Superannuation

Certain employees of the Company, who have joined post disinvestment are members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term Employee Benefits

Compensated absences

The Company has a policy on compensated absences which are both accumulating and non-accumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid/availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on nonaccumulating compensated absences is recognized in the period in which the absences occur. Actuarial differences are recognised immediately in the Statement of Profit and Loss.

n) Provision

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate.

(i) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that reflects the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of profit an

The Company also has wind power plants in the states of Rajasthan, Gujarat, Karnataka, Tamil Nadu and Maharashtra and solar power plants in the state of Rajasthan.

2. BASIS OF PREPARATION OF FINANCIAL STATEMENTS

A) BASIS OF PREPARATION

The financial statements of the company have been prepared in accordance with Indian Accounting Standards (Ind AS) notified under the Companies (Indian Accounting Standards) Rules 2015 (as amended from time to time) and presentation requirement of Division II of schedule III to the Companies Act 2013 (Ind AS compliant Schedule III), as applicable. The financial statements have been prepared on a historical cost convention on the accrual basis except for financial instruments which are measured at fair values (Refer note 3(a) below) and the provisions of the Companies Act, 2013 (''Act'') (to the extent notified). The Ind AS are prescribed under Section 133 of the Act read with Rule 3 of the Companies (Indian Accounting Standards) Rules, 2015, as amended.

Accounting policies have been consistently applied except where a newly issued accounting standard is initially adopted or a revision to an existing accounting standard requires a change in the accounting policy hitherto in use.

The financial statements were authorised for issue in accordance with a resolution of Board of Directors on May 02, 2019.

B) RECLASSIFICATION

(i) The Company has revised the presentation of forward premium relating to derivative instruments to present it along with the mark-to-market gain/loss on these instruments, as these more appropriately reflect the substance of the forward premiums on derivative transactions. As a result of the change, forward premium expense amounting to Rs. 37 Crore (year ended March 31,2019: Rs. 20 Crore) has been reclassified from ''Finance cost'' to ''other income'' for the comparative year ended March 31, 2018.

(ii) The classification of export incentives from government has also been revised to present it under ''other

operating income'', as the revised classification is more appropriate. As a result of the change, export incentives amounting to Rs. 97 Crore has been reclassified from ''revenue'' to'' other operating income'' for the comparative year ended March 31, 2018. Similarly, scrap sales and miscellaneous income amounting to Rs. 155 Crore and Rs. 54 Crore respectively have also been reclassified from ''revenue'' to ''other operating income'' for the comparative year ended March 31,2018.

The above reclassifications have no effect on either the equity as at March 31, 2018 or on the profit or cash flows for the year ended March 31, 2018.

3.(I) SIGNIFICANT ACCOUNTING POLICIES

A) FAIR VALUE MEASUREMENT

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

In the principal market for the asset or liability, or

In the absence of a principal market, in the most advantageous market for the asset or liability"

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant''s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

B) CURRENT AND NON-CURRENT CLASSIFICATION

The Company presents assets and liabilities in the balance sheet based on current/ non-current classification.

An asset is treated as current when it is:

Expected to be realized or intended to be sold or consumed in normal operating cycle

Held primarily for the purpose of trading

Expected to be realized within twelve months after the reporting period, or

Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period

All other assets are classified as non-current.

A liability is current when:

It is expected to be settled in normal operating cycle It is held primarily for the purpose of trading

It is due to be settled within twelve months after the reporting period, or

There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

C) FUNCTIONAL AND PRESENTATION CURRENCY

The financial statements are prepared in Indian Rupees (INR), which is the Company''s functional currency. All financial information presented in INR has been rounded to the nearest crores.

D) REVENUE RECOGNITION

(i) Sale of goods

Revenue from contracts with customers is recognised when control of the goods or services is transferred to the customer which usually is on delivery of the goods to the shipping agent at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. Revenue is recognised net of discounts, volume rebates, outgoing sales taxes/ goods and service tax and other indirect taxes excluding excise duty. Revenues from sale of by-products are included in revenue.

Certain of the Company''s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME), as specified in the contract. Revenue in respect of such contracts is recognised when control passes to the customer and is measured at the amount the entity expects to be entitled - being the estimate of the price expected to be received at the end of the measurement period. Post transfer of control of goods, provisional pricing features are accounted in accordance with Ind AS 109 ''Financial Instruments'' rather than Ind AS 115 and therefore the Ind AS 115 rules on variable consideration do not apply. These ''provisional pricing'' adjustments i.e. the consideration received post transfer of control are included in total revenue from operations on the face of the Statement of Profit and loss. Final settlement of the price is based on the applicable price for a specified future period. The Company''s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue.

Revenue from freight and insurance services is recognised over the period during which services are rendered.

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognised for the earned consideration when that right is conditional on Company''s future performance.

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company transfers goods or services to the customer, a contract liability is recognised when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognised as revenue when the Company performs under the contract.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, the Company does not adjust any of the transaction prices for the time value of money.

(ii) Sale of wind energy

Revenue from sale of wind power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognized in the statement of profit and loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, with reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset''s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists.

E) PROPERTY, PLANT AND EQUIPMENT

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and non-refundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended use. Plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any. Such cost includes the cost of replacing part of the plant and equipment and borrowing costs for long-term construction projects if the recognition criteria are met. The present value of the expected cost for the decommission ing of an asset and mine restoration after its use is included in the cost of the respective asset if the recognition criteria for a provision are met. Major machinery spares and parts are capitalized when they meet the definition of Property, Plant and Equipment. Expenditure incurred after the property, plant and equipment have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profit and Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading "Mining properties" in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will provide sufficient and sustainable return relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated. With respect to open pit operations, waste removal costs that are incurred in the open pit operations during the operational phase of these mines which provide improved access are recognized as assets. The cost of normal on-going operational stripping activities are recognized in the Statement of Profit and Loss as and when incurred.

When the benefit from the stripping costs are realized in the current period, the stripping costs are accounted as charge in statement of profit and loss account in deferred mining expenses head. Deferred stripping cost are included in mining properties within Property, Plant and Equipment and disclosed as a part of Mining properties. After initial recognition, the stripping activity asset is depreciated on a unit of production method over the expected useful life of the identified component of the ore body to which it improves access.

(Hi) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property, plant and equipment. Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on the straight-line method.

Depreciation has been provided over remaining useful life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining commercial ore reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off. Costs used in the computation of unit of production comprises the net book value of the capitalised costs plus the future estimated costs required to be incurred to access the commercial reserves.

Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

Assets

Useful life in years

Factory buildings

30 years

Residential buildings

60 years

Roads (included in buildings)

5-10 years

Computers and data processing equipment

3-6 years

Plant and Equipment (Including captive power plant)

8 years to 40 years

Railway sidings

15 years

Off ice equipment

5 years

Furniture and fixtures

10 years

Vehicles

8-10 years

The useful lives of the above assets are in line with the useful lives as prescribed under Part C of schedule II of the Companies Act, 2013, except plant and equipment pertaining to wind energy segment. The Company based on technical assessment made by technical experts and basis management estimate, depreciates these assets overestimated useful lives of 27 years over which the asset is expected to be used. The management believes that these estimated useful lives are realistic and reflect fair apportionment of the period over which the assets are likely to be used.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

v) Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of an asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the asset. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consists of interest and other costs than an entity incurs in connection with the borrowings of the funds.

F) INTANGIBLE ASSETS

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life. Software is amortized on straight line method over the useful life of the asset or 5 years whichever is shorter. Amounts paid for securing mining rights are amortized over the period of mining lease of 20 years. The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to reflect the changed pattern, if any.

G) IMPAIRMENT OF NON-FINANCIAL ASSETS

Impairment charges and reversals are assessed at the level of cash-generating units. A cash-generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

Impairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

If any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset''s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants and does not reflect the effects of factors that may be specific to the entity and not applicable to entities in general. Fair value for mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. These cash flows are discounted at an appropriate post tax discount rate to arrive at the net present value.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company''s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset''s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

H) FINANCIAL INSTRUMENTS

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition

All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

Debt instruments at amortized cost

A ''Debt instrument'' is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

Debt instruments at fair value through other comprehensive income (FVTOCI)

A ''debt instrument'' is classified as at the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset''s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method.

Debt instruments, derivatives and equity instruments at fair value through Statement of Profit or Loss (FVTPL)

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doingso reduces or eliminates a measurement or recognition inconsistency (Referred to as ''accounting mismatch''). The Company has not invested in any equity instruments.

Debt instrument included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company''s balance sheet) when:

The rights to receive cash flows from the asset have expired, or

The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ''pass-through'' arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company''s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets

In accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ''simplified approach'' for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/expense in the Statement of Profit and Loss (P&L). This amount is reflected under the head ''other expenses'' in the Statement of Profit and Loss (P&L). The balance sheet presentation for various financial instruments is described below:

Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

Debt instruments measured at FVTOCI: Since financial assets are already reflected at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ''accumulated impairment amount'' in the OCI.

For assessing increase in credit risk and impairment loss, the Company combines financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company''s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

• Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the Statement of Profit or Loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss.

• Financial Liabilities at amortized cost (Loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a non-derivative host contract - with the effect that some of the cash flows of the combined instrument vary in a way similar to a standalone derivative. An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a non-financial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

If the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does notseparate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets

The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the group''s operations. Such changes are evident to external parties. A change in the business model occurs when the group either begins or ceases to perform an activity that is significant to its operations. If the Company reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

I) DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGE ACCOUNTING

Initial recognition and subsequent measurement

In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge. The documentation includes the Company''s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument''s fair value in offsetting the exposure to changes in the hedged item''s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the Statement of Profit and Loss.

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met.

J) GOVERNMENT GRANTS, SUBSIDIES AND EXPORT INCENTIVES

Grants and subsidies from the government are recognized when there is reasonable assurance that (i) the Company will comply with the conditions attached to them, and (ii) the grant/subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit and Loss over the periods necessary to match them with the related costs, which they are intended to compensate.

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asset and presented within other income.

When the Company receives grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual instalments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favourable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

K) INVENTORIES

Inventories are valued at the lower of cost and net realizable value, less any provision for obsolescence.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-in-progress and finished goods (including significant by-products i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) Immaterial by-products, aluminium scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

L) TAXATION

Current tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

When the deferred tax liability arises from the initial recognition of good will or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the

reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognised outside profit or loss is recognised outside profit or loss (either in other comprehensive income or in equity). Deferred tax items are recognised in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

M) RETIREMENT AND OTHER EMPLOYEE BENEFIT SCHEMES

i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and

compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized as an expense as the related service is rendered by employees.

ii. Post-Employment Benefits Gratuity

In accordance with the Payment of Gratuity Act of 1972, the Company contributes to a defined benefit plan (the "Gratuity Plan"). The Gratuity Plan provides a lump sum payment to employees who have completed atleast5 years of service; at retirement, disability ortermination of employment being an amount equal to 15 days'' salary (based on the respective employee''s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

In respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Re-measurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

Net interest expense or income

Provident Fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ''Hindustan Zinc Limited Employee''s Contributory Provident Fund'' (''Trust'') accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any, between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family pension scheme. Contributions are paid during the year into the fund under statutory arrangements. The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss. The Company has no further obligation other than the contribution made.

Superannuation

Certain employees of the Company, who have joined post disinvestment a re members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term Employee Benefits Compensated absences

The Company has a policy on compensated absences which are both accumulating and non-accumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid/availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on non-accumulating compensated absences is recognized in the period in which the absences occur. Actuarial differences are recognised immediately in the Statement of Profit and Loss.

N) PROVISION

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognised as a finance cost. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate.

(i) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that reflects the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of profit and loss. Management estimates are based on third party technical estimates. The actual costs and cash outflows may differ from estimates because of changes in laws and regulations, changes in prices, analysis of site conditions and changes in restoration technology. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate.

(ii) Provision for Restoration, rehabilitation and environmental costs

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or on-going production of a mine. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalized at the start of each project as mining properties, as soon as the obligation to incur such costs arises. These costs are charged to the Statement of Profit and Loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision (considered as finance cost). The cost of the related asset is adjusted for changes in the provision due to factors such as updated cost estimates, changes to lives of operations, new disturbance and revisions to discount rates. The adjusted cost of the asset is depreciated prospectively over the lives of the assets to which they relate as per the depreciation policy.

Costs for the restoration of subsequent site damage, which is caused on an on-going basis during production, are charged to the Statement of Profit and Loss as extraction progresses. Where the costs of site restoration are not anticipated to be material, they are expensed as incurred.

O) FOREIGN CURRENCY TRANSLATION

The functional currency for the Company is determined as the currency of the primary economic environment in which it operates. For the Company, the functional currency is the local currency of the country in which it operates, which is Indian Rupee.

In the financial statements of the Company, transactions in currencies other than the functional currency are translated into the functional currency at the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in other currencies are translated into the functional currency at exchange rates prevailing on the reporting date. Non-monetary assets and liabilities denominated in other currencies and measured at historical cost or fair value are translated at the exchange rates prevailing on the dates on which such values were determined.

All exchange differences are included in the Statement of Profit and Loss except any exchange differences on monetary items designated as an effective hedging instrument of the currency risk of designated forecasted sales or purchases, which are recognized in the other comprehensive income.

P) EARNINGS PER SHARE

The Company presents basic and diluted earnings per share ("EPS") data for its equity shares. Basic EPS is calculated by dividing the profit or loss attributable to equity shareholders of the Company by the weighted average number of equity shares outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to equity shareholders and the weighted average number of equity shares outstanding for the effects of all dilutive potential equity shares.

Q) SEGMENT REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Operating Decision-Maker i.e. CEO. Revenue and expenses are identified to segments on the basis of their relationship to the operating activities of the segment. Revenue, expenses, assets and liabilities which are not allocable to segments on a reasonable basis, are included under "Unallocated revenue/ expenses/ assets/ liabilities".

R) LEASES

The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.

Company as a lessee

A lease is classified at the inception date as a finance lease or an operating lease. A lease that transfers substantially all the risks and rewards incidental to ownership to the Company is classified as a finance lease. Finance leases are capitalized at the commencement of the lease at the inception date fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are recognized as finance costs in the Statement of Profit and Loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Company''s general policy on the borrowing costs. Contingent rentals are recognized as expenses in the periods in which they are incurred. Operating lease payments are recognized as an expense in the Statement of Profit and Loss on a straight-line basis over the lease term.

Company as a lessor

Leases in which the Company does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Rental income from operating lease is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount ofthe leased asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

S) CASH AND CASH EQUIVALENTS

Cash and cash equivalents comprise cash at bank and on hand and short-term money market deposits with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value.

For the purpose of the statement of cash flows, cash and cash equivalents consist of cash and short-term deposits, as defined above and additionally includes unpaid dividend account.

T) INVESTMENT IN JOINT VENTURE

Investments representing equity interest in joint ventures are carried at cost. A joint venture is a joint arrangement whereby the parties that have joint control ofthe arrangement have rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

3.(ll) CHANGES IN ACCOUNTING POLICIES AND DISCLOSURES NEW AND AMENDED STANDARDS

The Company applied Ind AS 115 for the first time. The nature and effect of the changes as a result of adoption of these new accounting standards are described below.

Several other amendments and interpretations apply for the first time in March 2019, but do not have an impact on the financial statements of the Company.

Ind AS 115 - Revenue from Contracts with Customers

The Company has adopted Ind AS 115 Revenue from contracts with Customers with effect from April 01, 2018 which outlines a single comprehensive model for entities

to use in accounting for revenue arising from contracts with customers. The standard replaces most of the current revenue recognition guidance. The core principle of the new standard is for companies to recognize revenue when the control of the goods and services is transferred to the customer as against the transfer of risk and rewards. As per the Company''s current revenue recognition practices, transfer of control happens at the same point as transfer of risk and rewards thus not effecting the revenue recognition. The amount of revenue recognised reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.

Under this standard, services provided post transfer of control of goods are treated as separate performance obligation and require proportionate revenue to be deferred along with associated costs and to be recognized over the period of service. The Company provides shipping and insurances services after the date of transfer of control of goods and therefore has identified it as a separate performance obligation. As per the result of


Mar 31, 2018

1. COMPANY OVERVIEW

Hindustan Zinc Limited (“HZL” or “the Company”) was incorporated on January 10, 1966 and has its registered office at Yashad Bhawan, Udaipur (Rajasthan). HZL''s shares are listed on National Stock Exchange and Bombay Stock Exchange. The Company is engaged in exploring, extracting and processing of minerals.

HZL''s operations include five zinc-lead mines, four zinc smelters, one lead smelter, one zinc-lead smelter, seven sulphuric acid plants, one silver refinery plant and six captive power plants in the state of Rajasthan.

In addition, HZL also has a rock-phosphate mine in Matoon, near Udaipur in Rajasthan and zinc, lead, silver processing and refining facilities in the state of Uttarakhand. The Company also has wind power plants in the states of Rajasthan, Gujarat, Karnataka, Tamil Nadu and Maharashtra and solar power plants in the state of Rajasthan.

2. BASIS OF PREPARATION OF FINANCIAL STATEMENTS

A) BASIS OF PREPARATION

These financial statements are prepared on a going concern basis, in accordance with Indian Accounting Standards (Ind AS) under the historical cost convention on the accrual basis except for financial instruments which are measured at fair values (Refer note 3(a) below) and the provisions of the Companies Act, 2013 fAct1) (to the extent notified). The Ind AS are prescribed under Section 133 of the Act read with Rule 3 of the Companies (Indian Accounting Standards) Rules, 2015, as amended.

Accounting policies have been consistently applied except where a newly issued accounting standard is initially adopted or a revision to an existing accounting standard requires a change in the accounting policy hitherto in use.

The financial statements were approved for issue by the Board of Directors on April 30, 2018.

B) critical accounting ESTIMATE AND JUDGEMENT

The preparation of the financial statements in conformity with Ind AS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amount of assets, liabilities, income, expenses and disclosures of contingent liabilities at the date of these financial statements. Actual results may differ from these estimates under different assumptions and conditions.

The management believes that the estimates used in preparation of the financial statements are prudent and reasonable. Information about estimates and judgments made in applying accounting policies that have the most significant effect on the amounts recognized in the financial statements are as follows:

Significant Estimates

(i) Mining property and Ore reserve

Ore reserves and mineral resource estimates are estimates of the amount of ore that can be economically and legally extracted from the Company''s mining properties. The Company estimates its ore reserves and mineral resources based on information compiled by appropriately qualified persons relating to the geological and technical data on the size, depth, shape and grade of the ore body and suitable production techniques and recovery rates. Such an analysis requires complex geological judgments to interpret the data. The estimation of recoverable reserves is based upon factors such as estimates of foreign exchange rates, commodity prices, future capital requirements and production costs, along with geological assumptions and judgments made in estimating the size and grade of the ore body.

(ii) Restoration, rehabilitation and environmental costs:

Provision is made for costs associated with restoration and rehabilitation of mining sites as soon as the obligation to incur such costs arises. Such restoration and closure costs are typical of extractive industries and they are normally incurred at the end of the life of the mine or oil fields. The costs are estimated on the basis of mine closure plans and the estimated discounted costs of dismantling and removing these facilities and the costs of restoration are capitalized when incurred reflecting the Company''s obligations at that time. The provision for decommissioning liabilities (Refer note 16) is based on the current estimate of the costs for removing and decommissioning producing facilities, the forecast timing of settlement of decommissioning liabilities and the appropriate discount rate.

(iii) Assessment of Useful lives and consumption pattern of Property, Plant and Equipments:

The Company reviews the useful lives and consumption pattern of Property, Plant and Equipment at the end of each reporting period. This reassessment may result in change in depreciation expense in future periods (Refer note 2(c) and 3(e)).

Significant Judgment

Contingencies:

In the normal course of business, contingent liabilities may arise from litigation, taxation and other claims against the Company. Where it is management''s assessment that the outcome cannot be reliably quantified or is uncertain, the claims are disclosed as contingent liabilities unless the likelihood of an adverse outcome is remote. Such liabilities are disclosed in the notes but are not provided for in the financial statements.

While considering the possible, probable and remote analysis of taxation, legal and other claims, there is always a certain degree of judgment involved pertaining to the application of the legislation which in certain cases is supported by views of tax experts and/or earlier precedents in similar matters. Although there can be no assurance regarding the final outcome of the legal proceedings, the Company does not expect them to have a materially adverse impact on the Company''s financial position or profitability.

c) CHANGES IN SIGNIFICANT ESTIMATES

Change in pattern of utilization of plant and equipment.

The Company, basis an independent technical review and review of method of depreciation adopted by peer companies in the industry reassessed the method of charging depreciation basis actual economic benefits derived from asset and has decided to change the depreciation method for plant and equipment. Effective April 1, 2017, the method of depreciation on Plant and Equipment has been changed from Written Down Value Method to Straight Line Method on remaining useful life, resulting in lower depreciation charge of Rs,690 Crore during the current year. Further, the Company has also re-evaluated some of the other parameters associated for depletion computation including reassessing life of certain components and cost to complete, which has resulted in an additional amortization of Rs,369 Crore and has adjusted the same in depletion calculation.

The impact of the above changes in the estimates have resulted in a net decrease in depreciation charge of Rs,321 Crore and lower profits after tax of Rs,238 Crore for the year ended March 31, 2018.

3. significant accounting policies

A) FAIR value measurement

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

- I n the principal market for the asset or liability, or

- In the absence of a principal market, in the most advantageous market for the asset or liability"

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant''s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable"

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

B) CURRENT AND NON-CURRENT CLASSIFICATION

The Company presents assets and liabilities in the balance sheet based on current/ non-current classification.

An asset is treated as current when it is:

- Expected to be realized or intended to be sold or consumed in normal operating cycle

- Held primarily for the purpose of trading

- Expected to be realized within twelve months after the reporting period, or

- Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period "

All other assets are classified as non-current.

A liability is current when:

- It is expected to be settled in normal operating cycle

- It is held primarily for the purpose of trading

- It is due to be settled within twelve months after the reporting period, or

- There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as noncurrent assets and liabilities.

c) FUNCTIONAL AND PRESENTATION CURRENCY

The financial statements are prepared in Indian Rupees (INR), which is the Company''s functional currency. All financial information presented in INR has been rounded to the nearest Crores.

D) REVENUE RECOGNITION

Revenue is recognized to the extent that it is probable that economic benefit will flow to the Company and the revenue can be reliably measured, regardless of when the payment is being made. Revenues are measured at the fair value of the consideration received or receivable, net of discounts, volume rebates, sales taxes, Goods and Service Tax and other indirect taxes excluding excise duty. Based on the Educational Material on Ind AS 18 issued by the ICAI, the Group has assumed that recovery of excise duty (applicable through June 30, 2017) flows to the group on its own account. This is for the reason that it is a liability of the manufacturer which forms part of the cost of production, irrespective of whether the goods are sold or not. Since the recovery of excise duty flows to Company on its own account, revenue includes excise duty. However, sales tax/ value added tax (VAT) / Goods and Service Tax (GST) is not received by the Company on its own account. Accordingly, it is excluded from revenue.

(i) Sale of goods

Revenues from sales are recognized when all significant risks and rewards of ownership of the goods sold are transferred to the customer which usually is on delivery of the goods to the shipping agent/passage of title to customer and it can be reliably measured and it is reasonable to expect ultimate collection. Revenues from sale of byproducts are included in revenue. Certain of the Company''s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (“LME”), as specified in the contract, when shipped. Final settlement of the price is based on the applicable price for a specified future period. The Company''s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue. Revenue from operations comprises proceeds from sale of scrap net of disposal expenses.

(ii) Sale of wind energy

Revenue from sale of wind energy is recognized when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognized in the statement of profit and loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, by Reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset''s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists.

E) PROPERTY, PLANT AND EQUIPMENT

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and non-refundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended

use. The present value of the expected cost for the decommissioning of an asset and mine restoration after its use is included in the cost of the respective asset if the recognition criteria for a provision are met. Expenditure incurred after the property, plant and equipment have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell. Major machinery spares and parts are capitalized when they meet the definition of Property, Plant and Equipment.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profit and Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading “Mining properties” in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will provide sufficient and sustainable return relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated. With respect to open pit operations, waste removal costs that are incurred in the open pit operations during the operational phase of these mines which provide improved access are recognized as assets. The cost of normal on-going operational stripping activities are recognized in the Statement of Profit and Loss as and when incurred.

When the benefit from the stripping costs are realized in the current period, the stripping costs are accounted as charge in statement of profit and loss account in deferred mining expenses head. Deferred stripping cost are included in mining properties within Property, Plant and Equipment and disclosed as a part of Mining properties. After initial recognition, the stripping activity asset is depreciated on a unit of production method over the expected useful life of the identified component of the ore body to which it improves access.

(iii) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property, plant and equipment.

Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on the straight-line method.

- Depreciation has been provided over useful life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

- Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining commercial ore reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off. Costs used in the computation of unit of production comprises the net book value of the capitalised costs plus the future estimated costs required to be incurred to access the commercial reserves.

- Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

The useful lives of the above assets are in line with the useful lives as prescribed under Part C of schedule II of the Companies Act, 2013, except plant and equipment pertaining to wind energy segment. The Company based on technical assessment made by technical experts and basis management estimate, depreciates these assets over estimated useful lives over which the asset is expected to be used. The management believes that these estimated useful lives are realistic and reflect fair apportionment of the period over which the assets are likely to be used.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

F) INTANGIBLE ASSETS

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life. Software is amortized on straight line method over the useful life of the asset or 5 years whichever is shorter. Amounts paid for securing mining rights are amortized over the period of mining lease. The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to reflect the changed pattern, if any.

G) IMPAIRMENT OF NON-FINANCIAL ASSETS

Impairment charges and reversals are assessed at the level of cash-generating units. A cash-generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

Impairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

If any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset''s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants and does not reflect the effects of factors that may be specific to the entity and not applicable to entities in general. Fair value for mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. These cash flows are discounted at an appropriate post tax discount rate to arrive at the net present value.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company''s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset''s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

H) FINANCIAL INSTRUMENTS

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition

All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

- Debt instruments at amortized cost

A ‘Debt instrument'' is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

- Debt instruments at fair value through other comprehensive income (FVTOCI)

A ‘debt instrument'' is classified as at the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset''s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method.

- Debt instruments, derivatives and equity instruments at fair value through Statement of Profit or Loss (FVTPL)

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (Referred to as ''accounting mismatch'').The Company has not invested in any equity instruments.

Debt instrument included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company''s balance sheet) when:

- The rights to receive cash flows from the asset have expired, or

- The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through'' arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset."

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company''s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets

In accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

- Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

- Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ‘simplified approach'' for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/ expense in the Statement of Profit and Loss (P&L). This amount is reflected under the head ‘other expenses'' in the P&L. The balance sheet presentation for various financial instruments is described below:

- Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

- Debt instruments measured at FVTOCI: Since financial assets are already reflected at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ‘accumulated impairment amount'' in the OCI.

For assessing increase in credit risk and impairment loss, the Company''s financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company''s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

- Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the profit or loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied.

For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss.

- Financial Liabilities at amortized cost (Loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the

respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a non-derivative host contract - with the effect that some of the cash flows of the combined instrument vary in a way similar to a stand-alone derivative.

An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a non-financial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

If the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does not separate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets

The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the group''s operations.

Such changes are evident to external parties.

A change in the business model occurs when the group either begins or ceases to perform an activity that is significant to its operations.

If the Company reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

I) DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGE ACCOUNTING

Initial recognition and subsequent measurement

In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

- Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

- Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes the Company''s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument''s fair value in offsetting the exposure to changes in the hedged item''s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were designated.

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the Statement of Profit and Loss.

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the

hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met.

J) GOVERNMENT GRANTS, SUBSIDIES AND EXPORT INCENTIVES

Grants and subsidies from the government are recognized when there is reasonable assurance that (i) the Company will comply with the conditions attached to them, and (ii) the grant/subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit and Loss over the periods necessary to match them with the related costs, which they are intended to compensate.

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asse and presented within other income.

When the Company receives grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual installments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favorable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

K) INVENTORIES

Inventories are valued at the lower of cost and net realizable value, less any provision for obsolescence.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-in-progress and finished goods (including significant byproducts i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) Immaterial by-products, aluminum scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

L) TAXATION CURRENT TAX

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

- When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

- In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

- When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a

transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

- In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity).

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

M) RETIREMENT AND OTHER EMPLOYEE BENEFIT SCHEMES

i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized as an expense as the related service is rendered by employees.

ii. Post-Employment Benefits

Gratuity

In accordance with the Payment of Gratuity Act of

1972, the Company contributes to a defined benefit plan (the “Gratuity Plan”). The Gratuity Plan provides a lump sum payment to employees who have completed at least 5 years of service; at retirement, disability or termination of employment being an amount equal to 15 days'' salary (based on the respective employee''s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

In respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Remeasurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

- Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

- Net interest expense or income

Provident Fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ‘Hindustan Zinc Limited Employee''s Contributory Provident Fund'' (''Trust'') accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any, between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family pension scheme. Contributions are paid during the year into the fund under statutory arrangements.

The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss. The Company has no further obligation other than the contribution made.

Superannuation

Certain employees of the Company, who have joined post disinvestment are members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term Employee Benefits

Compensated absences

The Company has a policy on compensated absences which are both accumulating and non-accumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid/availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on non-accumulating compensated absences is recognized in the period in which the absences occur. Actuarial differences are recognized immediately in the Statement of Profit and Loss.

N) PROVISION

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows to net present value using an appropriate pre-tax discount rate that reflects current market assessments of the time value of money and, where appropriate, the risks specific to the liability. Unwinding of the discount is recognized in the Statement of Profit and Loss as a finance cost. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate.

(i) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that reflects current market assessment of time value of money and the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of profit and loss. Management estimates are based on third party technical estimates. The actual costs and cash outflows may differ from estimates because of changes in laws and regulations, changes in prices, analysis of site conditions and changes in restoration technology. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate.

(ii) Provision for Restoration, rehabilitation and environmental costs

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or on-going production of a mine. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalized at the start of each project as mining properties, as soon as the obligation to incur such costs arises. These costs are charged to the Statement of Profit and Loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision (considered as finance cost). The cost of the related asset is adjusted for changes in the provision due to factors such as updated cost estimates, changes to lives of operations, new disturbance and revisions to discount rates. The adjusted cost of the asset is depreciated prospectively over the lives of the assets to which they relate as per the depreciation policy.

Costs for the restoration of subsequent site damage, which is caused on an on-going basis during production, are charged to the Statement of Profit and Loss as extraction progresses. Where the costs of site restoration are not anticipated to be material, they are expensed as incurred.

O) FOREIGN currency TRANSLATION

The functional currency for the Company is determined as the currency of the primary economic environment in which it operates. For the Company, the functional currency is the local currency of the country in which it operates, which is Indian Rupee.

In the financial statements of the Company, transactions in currencies other than the functional currency are translated into the functional currency at the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in other currencies are translated into the functional currency at exchange rates prevailing on the reporting date. Non-monetary assets and liabilities denominated in other currencies and measured at historical cost or fair value are translated at the exchange rates prevailing on the dates on which such values were determined.

All exchange differences are included in the Statement of Profit and Loss except any exchange differences on monetary items designated as an effective hedging instrument of the currency risk of designated forecasted sales or purchases, which are recognized in the other comprehensive income.

P) EARNINGS PER SHARE

The Company presents basic and diluted earnings per share (“EPS”) data for its equity shares. Basic EPS is calculated by dividing the profit or loss attributable to equity shareholders of the Company by the weighted average number of equity shares outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to equity shareholders and the weighted average number of equity shares outstanding for the effects of all dilutive potential equity shares.

Q) SEGMENT REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Operating Decision-Maker i.e. CEO. Revenue and expenses are identified to segments on the basis of their relationship to the operating activities of the segment. Revenue, expenses, assets and liabilities which are not allocable to segments on a reasonable basis, are included under "Unallocated revenue/ expenses/ assets/ liabilities".

R) LEASES

The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfillment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.

Company as a lessee

A lease is classified at the inception date as a finance lease or an operating lease. A lease that transfers substantially all the risks and rewards incidental to ownership to the Company is classified as a finance lease. Finance leases are capitalized at the commencement of the lease at the inception date fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are recognized as finance costs in the Statement of Profit and Loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Company''s general policy on the borrowing costs. Contingent rentals are recognized as expenses in the periods in which they are incurred. Operating lease payments are recognized as an expense in the Statement of Profit and Loss on a straight-line basis over the lease term.

Company as a less or

Leases in which the Company does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Rental income from operating lease is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

S) CASH AND CASH EQUIVALENTS

Cash and cash equivalents comprise cash at bank and on hand and short-term money market deposits with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value.

For the purpose of the statement of cash flows, cash and cash equivalents consist of cash and short-term deposits, as defined above and additionally includes unpaid dividend account.

T) INVESTMENT IN JOINT VENTURE

Investments representing equity interest in joint ventures are carried at cost. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous


Mar 31, 2017

a) Fair value measurement

The Company measures financial instruments, such as, derivatives at fair value at each balance sheet date. 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. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

- In the principal market for the asset or liability, or

- In the absence of a principal market, in the most advantageous market for the asset or liability

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their best economic interest.

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities

Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable

Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

b) Current and non-current classification

The Company presents assets and liabilities in the balance sheet based on current/ non-current classification.

An asset is treated as current when it is:

- Expected to be realized or intended to be sold or consumed in normal operating cycle

- Held primarily for the purpose of trading

- Expected to be realized within twelve months after the reporting period, or

- Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period

All other assets are classified as non-current.

A liability is current when:

- It is expected to be settled in normal operating cycle

- It is held primarily for the purpose of trading

- It is due to be settled within twelve months after the reporting period, or

- There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classifies all other liabilities as noncurrent.

Deferred tax assets and liabilities are classified as noncurrent assets and liabilities.

The operating cycle is the time between the acquisition of assets for processing and their realization in cash and cash equivalents. The Company has identified twelve months as its operating cycle.

c) Functional and presentation currency

The financial statements are prepared in Indian Rupees (INR), which is the Company’s functional currency. All financial information presented in INR has been rounded to the nearest crores.

d) Revenue recognition

Revenue is recognized to the extent that it is probable that economic benefit will flow to the Company and the revenue can be reliably measured, regardless of when the payment is being made. Revenues are measured at the fair value of the consideration received or receivable, net of discounts, volume rebates, outgoing sales taxes and other indirect taxes excluding excise duty. Excise duty is a liability of the manufacturer which forms part of the cost of production, irrespective of whether the goods are sold or not. Since the recovery of excise duty flows to Company on its own account, revenue includes excise duty.

(i) Sale of goods

Revenues from sales are recognized when all significant risks and rewards of ownership of the goods sold are transferred to the customer which usually is on delivery of the goods to the shipping agent/passage of title to customer and it can be reliably measured and it is reasonable to expect ultimate collection. Revenues from sale of by products are included in revenue. Certain of the Company’s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (“LME”), as specified in the contract, when shipped. Final settlement of the price is based on the applicable price for a specified future period. The Company’s provisionally priced sales are marked to market using the relevant forward prices for the future period specified in the contract and is adjusted in revenue. Revenue from operations comprises proceeds from sale of scrap net of disposal expenses.

(ii) Sale of wind energy

Revenue from sale of wind energy is recognized when delivered and measured based on rates as per bilateral contractual agreements with buyers and at rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable.

(iii) Dividends

Dividend income is recognised in the statement of profit and loss only when the right to receive payment is established, provided it is probable that the economic benefits associated with the dividend will flow to the Company, and the amount of the dividend can be measured reliably.

(iv) Interest income

Interest income from a financial asset is recognised when it is probable that the economic benefits will flow to the Company and the amount of income can be measured reliably. Interest income is accrued on a time basis, by reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset’s net carrying amount on initial recognition.

(v) Others

Revenue relating to insurance claims and interest on delayed or overdue payments from trade receivable is recognized when no significant uncertainty as to measurability or collection exists. Export benefits are accounted for in the year of export based on eligibility and when there is no significant uncertainty in receiving the same.

e) Property, plant and equipment

(i) Property, plant and equipment other than mining properties

The initial cost of property, plant and equipment comprises its purchase price, including import duties and non-refundable purchase taxes, and any directly attributable costs of bringing an asset to working condition and location for its intended use.

It also includes the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Expenditure incurred after the property, plant and equipment have been put into operation, such as repairs and maintenance, are normally charged to the Statement of Profit and Loss in the period in which the costs are incurred. Major inspection and overhaul expenditure is capitalized.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized net within other income/other expenses in the Statement of Profit and Loss.

Assets held for sale are carried at lower of their carrying value or fair value less cost to sell. Major machinery spares parts are capitalized when they meet the definition of Property, Plant and Equipment.

The cost includes the cost of replacing part of the plant and equipment when significant part of plant and equipment are required to be replaced at intervals, the Company depreciates them separately based on their specific useful lives. All other repairs and maintenance cost are recognized in the Statement of Profits or Loss as incurred.

Government grant related to fixed asset is capitalized along with the asset that it relates to and depreciated over the life of the primary asset.

On transition to Ind As in respect of property, plant and equipment, the Company has applied Ind As retrospectively from the date of their acquisition.

(ii) Mining properties

The costs of mining properties, which include the costs of acquiring and developing mining properties are capitalized as Property, Plant and Equipment under the heading “Mining properties” in the year in which they are incurred. When a decision is taken that a Mining property is viable for commercial production (i.e. when the Company determines that the Mining Property will provide sufficient and sustainable return relative to the risks and the Company decided to proceed with the mine development), all further pre-production primary development expenditure other than land, buildings, plant and equipment is capitalized as developing asset until the mining property are capable of commercial production. Revenue derived during the project phase is adjusted from the cost incurred on the project from which such revenue is generated. With respect to open pit operations, waste removal costs that are incurred in the open pit operations during the operational phase of these mines which provide improved access are recognized as assets. The cost of normal on-going operational stripping activities are recognized in the Statement of Profit and Loss as and when incurred.

When the benefit from the stripping costs are realized in the current period, the stripping costs are accounted as charge in Statement of Profit and Loss in deferred mining expenses head. Deferred stripping costs are included in mining properties within Property, Plant and Equipment and disclosed as a part of Mining properties. After initial recognition, the stripping activity asset is depreciated on a unit of production method over the expected useful life of the identified component of the ore body to which it improves access.

(iii) Capital work in progress (CWIP)

Assets in the course of construction are capitalized in capital work in progress account. At the point when an asset is capable of operating in the manner intended by management, the cost of construction is transferred to the appropriate category of property plant and equipment. Costs associated with the commissioning of an asset are capitalized in CWIP until the period of commissioning has been completed and the asset is ready for its intended use.

(iv) Depreciation

Depreciable amount for assets is the cost of an asset, or other amount substituted for cost, less its estimated residual value. Depreciation on tangible property and other equipment has been provided on the straight-line method and written down value method of depreciation is followed for plant and machinery effective April 1, 2016.

- Depreciation has been provided over residual life of the respective property, plant and equipment in respect of additions arising on account of insurance spares, on additions or extension forming an integral part of existing plants and on the revised carrying amount of assets identified as impaired.

- Mining properties are amortized, from the date on which they are first available for use, in proportion to the annual ore raised to the remaining mineable ore reserves (on a unit-of-production basis) over the total estimated remaining commercial reserves of each property or group of properties and are subject to impairment review. Commercial reserves are proved and probable reserves and any changes affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. In the year of abandonment of mine, the residual balance in mining properties are written off.

- Based on technical evaluation, the management believes that the useful lives as given below best represent the period over which the management expects to use the asset.

The useful lives of the above assets are in line with the useful lives as prescribed under Part C of schedule II of the Companies Act, 2013, except plant and equipment pertaining to wind energy segment. The Company based on technical assessment made by technical experts and basis management estimate, depreciates these assets over estimated useful lives over which the asset is expected to be used. The management believes that these estimated useful lives are realistic and refect fair apportionment of the period over which the assets are likely to be used.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

f) Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

Intangible assets are amortized over their estimated useful life . Software is amortized on straight line method over the useful life of the asset or 5 years whichever is shorter. Amounts paid for securing mining rights are amortized over the period of mining lease.

The estimated useful life of the intangible assets and the amortization period are reviewed at the end of each financial year and the amortization period is revised to refect the changed pattern, if any.

g) Impairment of non-financial assets

Impairment charges and reversals are assessed at the level of cash-generating units. A cash-generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows from other assets or group of assets.

Impairment tests are carried out annually for all assets when there is an indication of impairment. The Company conducts an internal review of asset values annually, which is used as a source of information to assess for any indications of impairment or reversal of previously recognized impairment losses. External factors, such as changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognized impairment losses.

If any such indication exists then an impairment review is undertaken, the recoverable amount is calculated, as the higher of fair value less costs of disposal and the asset’s value in use.

Fair value less costs of disposal is the price that would be received to sell the asset in an orderly transaction between market participants and does not refect the effects of factors that may be specific to the entity and not applicable to entities in general. Fair value for mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects, and its eventual disposal, using assumptions that an independent market participant may take into account. These cash flows are discounted at an appropriate post tax discount rate to arrive at the net present value.

Value in use is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal. The cash flows are discounted using a pre-tax discount rate that refects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have not been adjusted. Value in use is determined by applying assumptions specific to the Company’s continued use and cannot take into account future development. These assumptions are different to those used in calculating fair value and consequently the value in use calculation is likely to give a different result to a fair value calculation.

The carrying amount of the CGU is determined on a basis consistent with the way the recoverable amount of the CGU is determined.

If the recoverable amount of an asset or CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount. An impairment loss is recognized in the Statement of Profit and Loss.

Any reversal of the previously recognized impairment loss is limited to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined if no impairment loss had previously been recognized.

h) Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

Financial assets - recognition

All financial assets are recognized initially at fair value plus, in the case of financial assets not recorded at fair value through profit and loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets except treasury investment that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset. Treasury investments are accounted for when the amount is settled in Bank account. For purposes of subsequent measurement, financial assets are classified in three categories:

- Debt instruments at amortized cost

A ‘Debt instrument’ is measured at the amortized cost if both the following conditions are met:

a) The asset is held within a business model whose objective is to hold assets for collecting contractual cash flows, and

b) Contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

After initial measurement, such financial assets are subsequently measured at amortized cost using the effective interest rate (EIR) method. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included in finance income in the Statement of Profit and Loss. The losses arising from impairment are recognized in the Statement of Profit and Loss. This category generally applies to trade and other receivables.

- Debt instruments at fair value through other comprehensive income (FVTOCI)

A ‘debt instrument’ is classified as at the FVTOCI if both of the following criteria are met:

a) The objective of the business model is achieved both by collecting contractual cash flows and selling the financial assets, and

b) The asset’s contractual cash flows represent SPPI.

Debt instruments included within the FVTOCI category are measured initially as well as at each reporting date at fair value. Fair value movements are recognized in the other comprehensive income (OCI). However, the Company recognizes interest income, impairment losses and reversals and foreign exchange gain or loss in the profit and loss. On derecognition of the asset, cumulative gain or loss previously recognized in OCI is reclassified from the equity to profit and loss. Interest earned whilst holding FVTOCI debt instrument is reported as interest income using the EIR method

- Debt instruments, derivatives and equity instruments at fair value through Statement of Profit or Loss (FVTPL)

FVTPL is a residual category for debt instruments. Any debt instrument, which does not meet the criteria for categorization as at amortized cost or as FVTOCI, is classified as at FVTPL.

In addition, the Company may elect to designate a debt instrument, which otherwise meets amortized cost or FVTOCI criteria, as at FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (referred to as ‘accounting mismatch’). The Company has not designated any debt instrument as at FVTPL.

Debt instruments, derivatives and equity instruments included within the FVTPL category are measured at fair value with all changes recognized in the Statement of Profit and Loss.

Financial assets - derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e. removed from the Company’s balance sheet) when:

- The rights to receive cash flows from the asset have expired, or

- The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass through arrangement, it evaluates if and to what extent it has retained the risks and rewards of ownership.

When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that refects the rights and obligations that the Company has retained.

Impairment of financial assets

In accordance with Ind AS 109, the Company applies expected credit loss (ECL) model for measurement and recognition of impairment loss on the following financial assets:

- Financial assets that are debt instruments, and are measured at amortized cost e.g., loans, debt securities, deposits and trade receivables

- Financial assets that are debt instruments and are measured as at FVTOCI

The Company follows ‘simplified approach’ for recognition of impairment loss allowance on trade receivables.

The application of simplified approach does not require the Company to track changes in credit risk. Rather, it recognizes impairment loss allowance based on lifetime ECLs at each reporting date, right from its initial recognition.

For recognition of impairment loss on other financial assets and risk exposure, the Company determines whether there has been a significant increase in the credit risk since initial recognition. If credit risk has not increased significantly, 12-month ECL is used to provide for impairment loss. However, if credit risk has increased significantly, lifetime ECL is used. If, in a subsequent period, credit quality of the instrument improves such that there is no longer a significant increase in credit risk since initial recognition, then the Company reverts to recognizing impairment loss allowance based on 12-month ECL.

Lifetime ECL are the expected credit losses resulting from all possible default events over the expected life of a financial instrument. The 12-month ECL is a portion of the lifetime ECL which results from default events that are possible within 12 months after the reporting date.

ECL is the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the entity expects to receive (i.e. all cash shortfalls), discounted at the original EIR.

ECL impairment loss allowance (or reversal) recognized during the period is recognized as income/ expense in the Statement of Profit and Loss (P&L). This amount is refected under the head ‘other expenses’ in the P&L.

The balance sheet presentation for various financial instruments is described below:

- Financial assets measured as at amortized cost: ECL is presented as an allowance, i.e., as an integral part of the measurement of those assets in the balance sheet. The allowance reduces the net carrying amount. Until the asset meets write-off criteria, the Company does not reduce impairment allowance from the gross carrying amount.

- Debt instruments measured at FVTOCI: Since financial assets are already refected at fair value, impairment allowance is not further reduced from its value. Rather, ECL amount is presented as ‘accumulated impairment amount’ in the OCI.

For assessing increase in credit risk and impairment loss, the Company’s financial instruments on the basis of shared credit risk characteristics with the objective of facilitating an analysis that is designed to enable significant increases in credit risk to be identified on a timely basis.

Financial liabilities - recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

- Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by Ind AS 109. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the profit or loss.

- Financial liabilities designated upon initial recognition at fair value through profit or loss are designated as such at the initial date of recognition, and only if the criteria in Ind AS 109 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognized in OCI. These gains/ loss are not subsequently transferred to Statement of Profit and Loss. However, the Company may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognized in the Statement of Profit and Loss. The Company has not designated any financial liability as at fair value through Profit and Loss

- Financial Liabilities at amortized cost (Loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the Statement of Profit and Loss.

Financial liabilities - derecognition

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability.

The difference in the respective carrying amounts is recognized in the Statement of Profit and Loss.

Embedded derivatives

An embedded derivative is a component of a hybrid (combined) instrument that also includes a non-derivative host contract - with the effect that some of the cash flows of the combined instrument vary in a way similar to a stand-alone derivative. An embedded derivative causes some or all of the cash flows that otherwise would be required by the contract to be modified according to a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable, provided in the case of a non-financial variable that the variable is not specific to a party to the contract. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through Profit or Loss.

If the hybrid contract contains a host that is a financial asset within the scope of Ind AS 109, the Company does not separate embedded derivatives. Rather, it applies the classification requirements contained in Ind AS 109 to the entire hybrid contract. Derivatives embedded in all other host contracts are accounted for as separate derivatives and recorded at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value though Profit or Loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss, unless designated as effective hedging instruments.

Reclassification of financial assets

The Company determines classification of financial assets and liabilities on initial recognition. After initial recognition, no reclassification is made for financial assets which are equity instruments and financial liabilities. For financial assets which are debt instruments, a reclassification is made only if there is a change in the business model for managing those assets. Changes to the business model are expected to be infrequent. The senior management determines change in the business model as a result of external or internal changes which are significant to the group’s operations. Such changes are evident to external parties. A change in the business model occurs when the group either begins or ceases to perform an activity that is significant to its operations. If the Company reclassifies financial assets, it applies the reclassification prospectively from the reclassification date which is the first day of the immediately next reporting period following the change in business model. The Company does not restate any previously recognized gains, losses (including impairment gains or losses) or interest.

Offsetting of financial instruments

Financial assets and financial liabilities are offset and the net amount is reported in the balance sheet if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

i) Derivative financial instruments and hedge accounting Initial recognition and subsequent measurement

In order to hedge its exposure to foreign exchange, interest rate, and commodity price risks, the Company enters into forward currency contracts, commodity contracts and other derivative financial instruments. The Company does not hold derivative financial instruments for speculative purposes.

Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are taken directly to profit or loss, except for the effective portion of cash flow hedges, which is recognized in OCI and later reclassified to profit or loss when the hedge item affects profit or loss or treated as basis adjustment if a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability.

For the purpose of hedge accounting, hedges are classified as:

- Fair value hedges when hedging the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment

- Cash flow hedges when hedging the exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment

At the inception of a hedge relationship, the Company formally designates and documents the hedge relationship to which the Company wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes the Company’s risk management objective and strategy for undertaking hedge, the hedging/ economic relationship, the hedged item or transaction, the nature of the risk being hedged, hedge ratio and how the entity will assess the effectiveness of changes in the hedging instrument’s fair value in offsetting the exposure to changes in the hedged item’s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they were

Hedges that meet the strict criteria for hedge accounting are accounted for, as described below:

(i) Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in profit or loss. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in Statement of Profit and Loss.

(ii) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in OCI in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the Statement of Profit and Loss.

Amounts recognized as OCI are transferred to Statement of Profit and Loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognized or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognized as OCI are transferred to the initial carrying amount of the non-financial asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met.

j) Government grants, subsidies and export incentives

Grants and subsidies from the government are recognized when there is reasonable assurance that

(i) the Company will comply with the conditions attached to them, and

(ii) the grant/subsidy will be received.

When the grant or subsidy relates to revenue, it is recognized as income on a systematic basis in the Statement of Profit and Loss over the periods necessary to match them with the related costs, which they are

Where the grant relates to an asset, it is recognized as deferred income and released to income in equal amounts over the expected useful life of the related asset and presented within other income.

When the Company receives grants of non-monetary assets, the asset and the grant are recorded at fair value amounts and released to profit or loss over the expected useful life in a pattern of consumption of the benefit of the underlying asset i.e. by equal annual instalments.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favourable interest is regarded as a government grant. The loan or assistance is initially recognized and measured at fair value and the government grant is measured as the difference between the initial carrying value of the loan and the proceeds received. The loan is subsequently measured as per the accounting policy applicable to financial liabilities.

k) Inventories

Inventories are valued at the lower of cost and net realizable value.

Costs incurred in bringing each product to its present location and condition are accounted for as follows:

(i) Ore, concentrate (mined metal), work-in-progress and finished goods (including significant by-products i.e. silver) are valued at lower of cost or net realizable value on weighted average basis.

(ii) Stores and spares are valued at lower of cost or net realizable value on weighted average basis.

(iii) Immaterial by-products, aluminium scrap, chemical lead scrap, anode scrap and coke fines are valued at net realizable value.

Net realizable value is determined based on estimated selling price, less further costs expected to be incurred to completion and disposal.

l) Taxation Current tax

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date.

Current income tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred tax

Deferred tax is provided, using the balance sheet method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred tax liabilities are recognized for all taxable temporary differences, except:

- When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss

- In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future

Deferred tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

- When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss.

- In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognized outside profit or loss is recognized outside profit or loss (either in other comprehensive income or in equity). Deferred tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Minimum Alternate Tax (‘MAT’) paid in a year is charged to the Statement of Profit and Loss as current tax. MAT paid in accordance with the tax laws, which gives future economic benefits in the form of adjustment to future income tax liability, is considered as an asset if there is convincing evidence that the Company will pay normal income tax. Accordingly, MAT is recognized as an asset in the Balance Sheet when it is probable that future economic benefit associated with it will flow to the Company.

m) Retirement and other Employee benefit schemes i. Short-term employee benefits

Employee benefits payable wholly within twelve months of receiving employee services are classified as short-term employee benefits. These benefits include salaries and wages, performance incentives and compensated absences which are expected to occur in next twelve months. The undiscounted amount of short-term employee benefits to be paid in exchange for employee services is recognized as an expense as the related service is rendered by employees.

ii. Post-Employment Benefits Gratuity

In accordance with the Payment of Gratuity Act of 1972, the Company contributes to a defined benefit plan (the “Gratuity Plan”). The Gratuity Plan provides a lump sum payment to employees who have completed at least 5 years of service; at retirement, disability or termination of employment being an amount equal to 15 days’ salary (based on the respective employee’s last drawn salary) for every completed year of service.

Based on actuarial valuations conducted as at year end, a provision is recognized in full for the benefit obligation over and above the funds held in the Gratuity Plan.

In respect of defined benefit schemes, the assets are held in separately administered funds. In respect of defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation separately each year using the projected unit credit method by independent qualified actuary as at the year end.

Re-measurements, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability), are recognized immediately in the balance sheet with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Remeasurements are not reclassified to the Statement of Profit and Loss in subsequent periods.

The Company recognizes the following changes in the net defined benefit obligation as an expense in the Statement of Profit and Loss:

- Service costs comprising current service costs, past-service costs, gains and losses on curtailments and non-routine settlements; and

- Net interest expense or income Provident Fund

The Company offers retirement benefits to its employees, under provident fund scheme which is a defined benefit plan. The Company and employees contribute at predetermined rates to ‘Hindustan Zinc Limited Employee’s Contributory Provident Fund (‘Trust’) accounted on accrual basis and the conditions for grant of exemption stipulate that the employer shall make good the deficiency, if any, between the return guaranteed by the statute and actual earning of the Trust. The contribution towards provident fund is recognized as an expense in the Statement of Profit and Loss.

Family Pension

The Company offers its employees benefits under defined contribution plans in the form of family pension scheme. Contributions are paid during the year into the fund under statutory arrangements.

The contribution to family pension fund is made at predetermined rates by the Company based on prescribed rules of family pension scheme. The contribution towards family pension is recognized as an expense in the Statement of Profit and Loss.

Superannuation

Certain employees of the Company, who have joined post disinvestment are members of the Superannuation plan. The Company has no further obligations to the Plan beyond its monthly contributions which are periodically contributed to a trust fund, the corpus of which is invested with the Life Insurance Corporation of India. The contribution is recognized as an expense in the Statement of Profit and Loss.

iii. Other Long-Term Employee Benefits

The Company has a policy on compensated absences which are both accumulating and nonaccumulating in nature. The expected cost of accumulating compensated absences is determined by actuarial valuation performed by an independent actuary at each balance sheet date using projected unit credit method on the additional amount expected to be paid/availed as a result of the unused entitlement that has accumulated at the balance sheet date. Expense on non-accumulating compensated absences is recognized in the period in which the absences occur.

n) Provision

(i) General

Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources, that can be reliably estimated, will be required to settle such an obligation. If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows to net present value using an appropriate pretax discount rate that refects current market assessments of the time value of money and, where appropriate, the risks specific to the liability. Unwinding of the discount is recognized in the Statement of Profit and Loss as a finance cost. Provisions are reviewed at each reporting date and are adjusted to refect the current best estimate.

(ii) Provision for Decommissioning

The Company recognizes a provision for decommissioning costs of smelting and refining facilities. Decommissioning costs are provided at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the particular asset. The cash flows are discounted at pre-tax rate that refects current market assessment of time value of money and the risks specific to the liability. The unwinding of the discount is expensed as incurred and recognized in the Statement of Profit and Loss as a finance cost. Changes in the estimated future costs or in the discount rate applied are added to or deducted from the cost of the asset.

The Company recognizes provision for discontinuing of a smelting operation which is charged to the Statement of Profit and Loss. Management estimates are based on third party technical estimates. The actual costs and cash outflows may differ from estimates because of changes in laws and regulations, changes in prices, analysis of site conditions and changes in restoration technology. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate.

(iii) Provision for Restoration, rehabilitation and environmental costs

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the development or ongoing production of a mine. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalized at the start of each project, as soon as the obligation to incur such costs arises. These costs are charged to the Statement of Profit and Loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision (considered as finance cost). The cost of the related asset is adjusted for changes in the provision due to factors such as updated cost estimates, changes to lives of operations, new disturbance and revisions to discount rates. The adjusted cost of the asset is depreciated prospectively over the lives of the assets to which they relate.

Costs for the restoration of subsequent site damage, which is caused on an on-going basis during production, are charged to the Statement of Profit and Loss as extraction progresses. Where the costs of site restoration are not anticipated to be material, they are expensed as incurred.

o) Foreign currency translation

The functional currency for the Company is determined as the currency of the primary economic environment in which it operates. For the Company, the functional currency is the local currency of the country in which it operates, which is Indian Rupee.

In the financial statements of the Company, transactions in currencies other than the functional currency are translated into the functional currency at the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in other currencies are translated into the functional currency at exchange rates prevailing on the reporting date. Non-monetary assets and liabilities denominated in other currencies and measured at historical cost or fair value are translated at the exchange rates prevailing on the dates on which such values were determined.

All exchange differences are included in the Statement of Profit and Loss except any exchange differences on monetary items designated as an effective hedging instrument of the currency risk of designated forecasted sales or purchases, which are recognized in the other comprehensive income.

p) Earnings per share

The Company presents basic and diluted earnings per share (“EPS”) data for its equity shares. Basic EPS is calculated by dividing the profit or loss attributable to equity shareholders of the Company by the weighted average number of equity shares outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to equity shareholders and the weighted average number of equity shares outstanding for the effects of all dilutive potential equity shares.

q) Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Operating Decision-Maker i.e. CEO. Revenue and expenses are identified to segments on the basis of their relationship to the operating activities of the segment. Revenue, expenses, assets and liabilities which are not allocable to segments on a reasonable basis, are included under “Unallocated revenue/ expenses/ assets/ liabilities”.

r) Leases

The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.

For arrangements entered into prior to April 1, 2015, the Company has determined whether the arrangements contain lease on the basis of facts and circumstances existing on the date of transition.

Company as a lessee

A lease is classified at the inception date as a finance lease or an operating lease. A lease that transfers substantially all the risks and rewards incidental to ownership to the Company is classified as a finance lease. Finance leases are capitalized at the commencement of the lease at the inception date fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability.

Finance charges are recognized as finance costs in the Statement of Profit and Loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Company’s general policy on the borrowing costs. Contingent rentals are recognized as expenses in the periods in which they are incurred. Operating lease payments are recognized as an expense in the Statement of Profit and Loss on a straight-line basis over the lease term.

Company as a lessor

Leases in which the Company does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Rental income from operating lease is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

s) Cash and cash equivalents

Cash and cash equivalents comprise cash at bank and on hand and short-term money market deposits with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value.

For the purpose of the statement of cash flows, cash and cash equivalents consist of cash and short-term deposits, as defined above, net of outstanding bank overdrafts as they are considered an integral part of the Company’s cash management.

t) Cash dividend to equity shareholders of the Company

The Company recognizes a liability to make distribution to equity shareholders of the Company when the distribution is authorized and it is no longer at the discretion of the Company. Interim dividend is paid as and when declared by the Board. Final dividend is paid after obtaining shareholders’ approval. Dividends are paid in Indian Rupees.

u) Investment in joint venture

Investments representing equity interest in joint ventures are carried at cost. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

v) Standards issued but not effective

In March 2017, the Ministry of Corporate Affairs issued the Companies (Indian Accounting Standards) (Amendments) Rules, 2017, notifying amendments to Ind AS 7, ‘Statement of cash flows’ and Ind AS 102, ‘Share-based payment.’ These amendments are in accordance with the recent amendments made by International Accounting Standards Board (IASB) to IAS 7, ‘Statement of cash flows’ and IFRS 2, ‘Share-based payment,’ respectively. The amendments are applicable to the Company from April 1, 2017.

Amendment to Ind AS 7:

The amendment to Ind AS 7 requires the entities to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes, suggesting inclusion of a reconciliation between the opening and closing balances in the balance sheet for liabilities arising from financing activities, to meet the disclosure requirement.

Amendment to Ind AS 102:

The amendment to Ind AS 102 provides specific guidance to measurement of cash-settled awards, modification of cash-settled awards and awards that include a net settlement feature in respect of withholding taxes. It clarifies that the fair value of cash-settled awards is determined on a basis consistent with that used for equity-settled awards. Market-based performance conditions and non-vesting conditions are refected in the ‘fair values’, but non-market performance conditions and service vesting conditions are refected in the estimate of the number of awards expected to vest. Also, the amendment clarifies that if the terms and conditions of a cash-settled share-based payment transaction are modified with the result that it becomes an equity-settled share-based payment transaction, the transaction is accounted for as such from the date of the modification. Further, the amendment requires the awards that include a net settlement feature in respect of withholding taxes to be treated as equity-settled in its entirety. The cash payment to the tax authority is treated as if it was part of an equity settlement.

The Company will adopt these amendments from their applicability date. The Company is evaluating the requirements of the amendment along with the impact on the financial statements.


Mar 31, 2015

A) BASIS OF ACCOUNTING

The financial statements of the Company have been prepared in accordance with the Generally Accepted Accounting Principles in India (Indian GAAP) to comply with the Accounting Standards specified under Section 133 of the Companies Act, 2013, read with Rule 7 of the Companies (Accounts) Rules, 2014 and the relevant provisions of the Companies Act, 2013 ("the 2013 Act"), as applicable.

The accounting policies adopted in the preparation of the financial statements are consistent with those followed in the previous year except for change in the accounting policy for depreciation as more fully described in Note 30.

b) USE OF ESTIMATES

The preparation of the financial statements in conformity with Indian GAAP requires the Management to make estimates and assumptions considered in the reported amounts of assets and liabilities (including contingent liabilities) and the reported income and expenses during the year. The Management believes that the estimates used in preparation of the financial statements are prudent and reasonable. Future results could differ due to these estimates and the differences between the actual results and the estimates are recognised in the periods in which the results are known / materialise.

c) FIXED ASSETS (TANGIBLE AND INTANGIBLE)

Grant received towards fixed assets is reduced from the cost of the related assets. Machinery spares which can be used only in connection with an item of fixed asset and whose use is expected to be irregular are capitalised and depreciated over the useful life of the principal item of the relevant assets. Subsequent expenditure on fixed assets after its purchase or completion is capitalised only if such expenditure results in an increase in the future benefits from such asset beyond its previously assessed standard of performance.
