| • | Climate change risks, if not managed adequately, can affect our operations and profitability. |
| • | We are exposed to competitive pressures in our various business segments in which we operate which could result in lower prices or sales volumes of the products we produce, which may cause our profitability to suffer. |
| • | We depend upon third parties for supply of a portion of our raw material requirements, for the continuance of our operations, and for execution of our projects and supply of equipment and services, as well as for off take of our production volumes. |
| • | Defects in title or loss of any leasehold interests in our properties could limit our ability to conduct operations on such properties or result in significant unanticipated costs. |
| • | Commodity prices and the copper treatment and refinery charges or TcRc may be volatile, which may have a material adverse effect on our revenue, results of operations and financial condition. |

| • | Acquisition risks non-Indian companies, we may not be able to satisfy certain Indian regulatory requirements for such acquisitions and may need to obtain the prior approval of the Reserve Bank of India (“RBI”) which we may not be able to obtain. The funding of such acquisitions by us may require certain approvals from regulatory authorities in India. In addition, acquisitions and investments involve a number of risks, including possible adverse effects on our operating results, diversion of management’s attention, failure to retain key personnel, risks associated with unanticipated events or liabilities and difficulties in the assimilation of the operations, technologies, systems, services and products of the acquired businesses or investments. Any failure to achieve successful integration of such acquisitions or investments could have a material adverse effect on our business, financial condition and results of operations. |

| • | permits, authorizations or rights granted to third parties that could conflict with, and require the Company to alter its expansion or new project plans; |
| • | delays or higher than expected costs in obtaining the necessary equipment, machinery, materials, supplies, labor or services and in implementing new technologies to develop and operate a project; |
| • | conflicts with local communities and/or strikes or other labor disputes may delay the implementation or the development of projects; |
| • | accidents, natural disasters and equipment failures, as well as major public health issues such as the COVID-19 pandemic, could result in delays, cost overruns, or the suspension or cancelation of projects; and |
| • | changes in market conditions or regulations may make a project less profitable than expected at the time the Company initiated work on it. |
| • | Disruptions in extraction and production due to equipment failures, unexpected maintenance problems and other interruptions: |
| • | Availability of raw materials for production and energy requirements: |
| • | Availability of water: |
| • | Disruptions to or increased costs of transport services : |
| • | Inadequate plant operating and maintenance procedures : |
| • | Dependence on third parties: sub-contractors and thereby have limited influence and control over the risks that arises. Ensuring the delivery of services and equipment, executing the projects as per schedule, of the right quality and managing safety and security of personnel and materials at the sites as well as during transportation, and ensuring all regulatory compliances are met, could pose a potential challenge. Any delays in any of these aspects could have an adverse impact on operations and project completion by way of cost and schedule overruns and adversely effects our operational and financial performance. We review the progress jointly with the partner at regular intervals to mitigate this potential risk. Further, our business partners may be unable or unwilling to fully compensate us against costs we may incur on their behalf or on behalf of the joint venture. For instance, the external contractors may not be able to complete construction and installation on time, within budget, or to the specifications set forth in our contracts with them, or the contractors may otherwise cause delays in meeting project milestones or achieving commercial operation by the scheduled completion date or operational deliverables, which could in turn cause forecast budgets to be exceeded or result in delayed payment by customers, invoke liquidated damages, penalty clauses or performance guarantees or result in termination of contracts. See “Item 8: Financial Information - A. Consolidated Statements and Other Financial Information - Legal Proceedings - Proceedings against TSPL relating to its delay in commissioning various units of the power plant |

| • | Regulatory compliance: 2 ) emission from thermal power plants through installation of Flue Gas Desulphurization (“FGD”). Noncompliance of the published norms within prescribed timelines will have an adverse impact on operations by way of environmental compensation.” |
| • | Flow assurance concerns of crude oil: 24-inch insulated oil pipeline and connecting spur lines should be kept at a temperature greater than the temperature at which crude oil starts to solidify (i.e. pour point). Maintaining the temperature of the crude oil above pour point temperature has required the installation of a specialized heating system and heating stations at various points along the pipeline. If the specialized heating system does not perform as expected, or there are problems associated with the performance of the heating stations, or there are problems supplying fuel to the power generation systems at these heating stations, then the temperature of crude oil may not be maintained, which would have an adverse impact on the rate at which oil can be transported through the pipeline. Any reduction in the crude oil production, ultimate recovery, or in the oil transportation may have a material adverse effect on our business, financial condition and results of operations. |
| • | Tailings dam failure: |
| • | Accidents at mines, oil fields, smelters, refineries, oil processing terminals, cargo terminals and related facilities: open-pit mining operations include flooding of the open-pit and collapses of the open-pit wall. Hazards associated with our underground mining operations include underground fires and explosions, including those caused by flammable gas, cave-ins or ground falls, discharge of gases and toxic chemicals, flooding, sinkhole formation and ground subsidence and other accidents and conditions resulting from drilling and removing and processing material from an underground mine. If any of these hazards or accidents result in significant injury to employees and damage to equipment or other property, we may experience unexpected production loss, increased production costs, and increased capital expenditures to repair or replace equipment or property, as well as claims from affected employees and environmental and other authorities for any alleged breaches of applicable laws or regulations. Disruptions to mining, delays and costs on account of such hazards or accidents could have a material adverse effect on our business, financial condition and results of operations. |
| • | Strikes and industrial actions or disputes: |
| • | any change in our capital structure, |
| • | issue of equity, preferential capital or debentures, |
| • | raising any loans and deposits from the public, |
| • | undertaking any new project, |

| (1) | A gross well or acre is a well or acre in which a working interest is owned, while a net well or acre is deemed to exist when the sum of fractional ownership working interests in gross wells or acres equals one. |
| (2) | Developed acreage is acreage assignable to productive wells; productive wells include producing wells and wells mechanically capable of producing. |
| (3) | Undeveloped acreage encompasses those leased acres on which wells have not been drilled or completed to a point that would permit the production of economic quantities of oil or gas regardless of whether such acreage contains proved reserves. Users of this information should not confuse undeveloped acreage with undrilled acreage held by production under the terms of the lease. Cairn’s lease holdings comprise earlier five blocks and new 53 blocks acquired under OALP and DSF-2 round in India. |

| Chotia Coal Mine, Tehsil-Podiuprodha District Korba State: Chhattisgarh |
-Public road -Coal transported by road to BALCO plant in Korba District -Distance between mines and BALCO plant is 73 Km |
BALCO-100.0% | -MDO-Mode Currently no MDO exists as mining operations are temporarily suspended due to COVID-19. |
-Mining lease granted. -Mining lease is valid for 20 years -Lease executed on October 16, 2015 -Valid until-October 15, 2035 |
Mines commenced coal production in 2006 (by prior allottee, M/s Prakash Industries Ltd.) However, BALCO commenced coal mining operations in 2015 |
-Open Cast and Underground -Opencast is operational since 2006 (by prior allottee, M/s Prakash Industries Ltd.) -No infrastructure is developed by prior allottee for underground hence no coal production from underground mine. Mining Plan has been revised by BALCO accordingly. -Thermal coal is mined from barakar formation of permian age of Gondwana supergroup -Low moisture thermal coal |
Electricity is available from Rural Feeder of Chhattisgarh State Electricity Board | Site office, explosive magazine, diesel pump, store, weigh bridge, residential complex is available at site |
| • | Captive Coal Block at Chotia – BALCO sources coal from its own coal mine which has annual coal production capacity of one million tons and BALCO produced 0.002 million tons and 1.0 million tons during fiscal year 2021 and 2020 respectively and 0.67 million tons during fiscal year 2019. No production was generated in FY 2022, as the Mining operations at BALCO’s Chotia Coal Mine Block have been suspended since July 1, 2021 since low GCV has rendered operations uneconomical. |
| • | Other Sources – BALCO sources coal from other sources such as the GoI’s coal mining companies, long-term coal supply agreements and from imports. In fiscal year 2021, the total coal purchased from these other sources was 7.48 million tons. Set forth below is a map depicting the location of our coal properties for our coal mining operations: |

| (2) | Cost of production per unit is not a recognized measure under IFRS as issued by the IASB. We have included cost of production as it is a key performance indicator used by the management to assess the performance of our operations. We also believe it is a measure used by investors and analysts to evaluate companies in our industry. Our results of operations are, to a significant degree, dependent upon our ability to efficiently run our operations and maintain low costs of production. Efficiencies relating to recovery of metal from the ore, process improvements, by-product management and increasing productivity help drive our costs down. Our computation of cost of production should be considered in addition to, and not as a substitute for other measures of financial performance and liquidity reported in accordance with IFRS as issued by the IASB. Cost of production is a measure intended for monitoring the operating performance of our operations. This measure is presented by other metal companies, though our measure may not be comparable to similarly titled measures reported by other companies. |
| (3) | Cost of production of zinc before by-product revenue increased from $ 1,401 per ton for fiscal year 2021 to $ 1,723 per ton for fiscal year 2022. The increase is mainly due to higher coal prices and input commodity inflation partly offset by higher volume, better Sulphuric Acid realizations and improved recoveries. The cost of production of zinc net of by-product revenue increased from $ 1,286 per ton in fiscal year 2021 to $ 1,567 per ton in fiscal year 2022. The increase was due to aforementioned reasons partially offset by higher sulphuric acid credit on account of higher net sales realisation (“NSR”) in fiscal year 2022. |
| (4) | Cost of production for Zinc International net of by-product credit increased from $1,307 per ton to $1,442 per ton, an increase of 10.4%. This was mainly driven by higher mining costs, TCRCs, exchange rate appreciation and annual inflation offset by higher production at Gamsberg. Cost of production before by-product revenue increased from $1,479 to $1,673. |
| (5) | Cost of production for oil and gas, increased to $ 35.7 per net boe in fiscal year 2022 from $ 21.7 per net boe in fiscal year 2021, primarily on account of increase in cess on ad-valorem basis due to increase in average Brent price realizations and Increase in JV expenses due to increase in Polymer prices. |
| (6) | Cost of production for iron ore, decreased from $ 17.2 per ton in fiscal year 2021 to $ 14.9 per ton in fiscal year 2022. We bought 1.1 million tonnes low grade iron ore in auctions held by Goa Government in Auction No -25,26 and 27. These ore along with opening stock of ore purchased in 23rd and 24th auction and fresh royalty paid ore moved out of mines post the Hon’ble Supreme Court order, were then beneficiated and around 1.1 million tonnes were exported. |
| (7) | Cost of production for copper has increased from ¢/lb 14.2 to ¢/lb 14.9 primarily on account of higher fuel cost in fiscal year 2022, partially offset by operational efficiencies. |
| (8) | Cost of production for Aluminium before adjusting by-product revenue increased from $ 1,347 per ton in fiscal year 2021 to $ 1,858 per ton in fiscal year 2022. The increase is on account of headwinds in cost due to rising commodity prices and the coal crisis, we undertook several structural initiatives to make our business immune from market induced volatilities. The cost of production net of by-product credit increased from $ 1,347 per ton in fiscal year 2021 to $ 1,855 per ton in fiscal year 2022. |
| (9) | Cost of production for steel business has increased from $ 386 per ton to $ 576 per ton in the fiscal year 2022. This was primarily due to increase of coking coal prices and significant losses in operational inefficiencies. |
| (10) | Power cost at Jharsuguda 600 MW plant has marginally increased from ₹ ₹ |
| (i) | Cost of production before by-product revenue, which represents the direct costs relating to production and conversion costs of metal (such as energy costs, ore extraction costs and processing costs at our captive mines, labor costs and other manufacturing expenses), excluding depreciation, impairment charges and finance costs, and |
| (ii) | Cost of production net of by-product revenues which represents cost of production before by-product revenue offset by any amounts we receive upon sale of by-products from such operations. Offsetting by-product revenues is useful to the management and investors to compare our cost competitiveness with our peers in the industry as it is a common metric used by our peers in the industry. |
| • | In the case of Zinc India operations, where we have integrated operations from production of zinc ore to zinc metal, cost of production before by-product revenue is the cost of extracting ore and conversion of the ore into zinc metal ingots. Payment of royalty and provision towards contribution to DMF and NMET is included in determining the cost of production. Cost of production net of by-product revenue represents cost of production before by-product revenue, net of revenue earned from the by-product sulphuric acid, which is deducted from the cost of production consistent with the industry practice. The total cash cost before by-product revenue and net of by-product revenue is divided by the total number of tons of zinc metal produced to calculate the cost of production before by-product revenue and net of by-product revenue per ton of zinc metal. Our Zinc India segment primarily consists of zinc ingot production and lead is only a co-product of zinc while silver is a by-product arising from lead smelting process. Accordingly, the cost of production presented for Zinc India operations is only for zinc ingot production and the cost of production of lead and silver are not presented. |
| • | Our Zinc International operations consist of the Skorpion mine and refinery in Namibia, Black Mountain mine, which includes new Gamsberg mine in South Africa and the Lisheen mine in Ireland which ceased operations in December 2015. Skorpion produces special high-grade zinc ingots. As a result, the cost of production before by-product revenue with respect to the Skorpion mine consists of the total direct cost of mining zinc ore and producing zinc in the refinery through a leaching, refining and electrowinning process. Skorpion mine does not produce any material by-products. Skorpion Zinc has been under Care and Maintenance since the start of April 2020, following cessation of mining activities due to geotechnical instabilities in the open pit. Activities to restart the mine are progressing well. Cost of production before by-product revenue of zinc at Black Mountain mine consists of direct mining costs, concentrate costs, TcRc and direct services cost. Cost of production net of by-product revenue represents cost of production before by-product revenue, net of revenue from copper consistent with the industry practice. At Black Mountain mine lead is only a co-product of zinc while silver is a by-product of lead. Accordingly, the cost of production presented for Black Mountain mine is only for zinc production and the cost of production of lead and silver are not presented. Royalties paid are also included in the cost of production. The total cash cost before by-product revenue and net of by-product revenue is divided by the total number of tons of zinc metal produced or zinc metal in concentrate produced to calculate the cost of production before by-product revenue and net of by-product revenue per ton of zinc metal produced or zinc metal in concentrate produced. Gamsberg mine has been ramping up well in fiscal year 2022. Cost of production before by-product revenue of zinc at Gamsberg consists of direct mining costs, concentrate costs, TcRc and direct services cost. Gamsberg mine does not produce any material by-products. |
| • | The cost of production in our oil and gas business consists of expenditure incurred towards the production of crude oil and natural gas including statutory levies, such as cess, royalties (except the RJ block) and production payments payable pursuant to the PSC’s as well as operational expenditures such as costs relating to manpower, repairs and maintenance of facilities, power generation and fuel for such facilities, water injection, insurance, and storage, transportation and freight of crude oil and natural gas, among others. Cess forms a major component of the cost of production and any change in the rate of the cess will impact the result of the operations. The total production cost is divided by the entitlement interest quantity of oil and gas produced to determine the cost of production per barrel of oil equivalent. |
| • | In the case of iron ore, cost of production relates to the iron ore mining and processing cost. Payment of royalty fees and provision towards contribution to DMF and NMET are included in determining the cost of production at Goa, whereas at Karnataka iron ore business royalties are under scope of buyer. The total cost is divided by the total number of tons of iron ore produced to calculate the cost of production per ton of iron ore. Our iron ore segment also includes met coke and pig iron. However, the cost of production presented for iron ore operations does not include met coke and pig iron. |
| • | Our iron ore operations in Goa were recommenced in August 2015, after receiving necessary approvals from the Goa state government. Our iron ore operations had been suspended till fiscal year 2015 due to the continued mining ban in the state of Goa. The Hon’ble Supreme Court passed its final order in the matter on February 7, 2018 wherein it set aside the second renewal of the mining leases granted by the State of Goa. The Hon’ble Supreme Court directed all lease holders operating under a second renewal to stop all mining operations with effect from March 16, 2018 until fresh mining leases (not fresh renewals or other renewals) and fresh environmental clearances are granted under the Mines and Minerals (Development and Regulation) (MMDR) Act. We continue to engage with the Government for the resumption of mining operations. |
| • | In the case of copper, cost of production before by-product and free copper revenue relates only to our custom smelting and refining operations (and not for our mining operations) and consists of the cost of converting copper concentrate into copper cathodes, including the cost of freight of copper anodes from Tuticorin to Silvassa. Cost of production net of by-product and free copper revenue represents cost of production before by-product and free copper revenue, net of revenue earned from the sale of by-product, sulphuric acid and copper metal recovered in excess of paid copper metal are deducted from the cash costs, in line with the cost reporting practice of custom smelters globally. The total cash costs before by-product and free copper revenue and net of by-product and free copper revenue are divided by the total number of pounds of copper metal produced to calculate the cost of production before by-product and free copper revenue and net of by-product and free copper revenue per pound of copper metal produced. |
| • | The TNPCB through an order, dated April 9, 2018, rejected the consent renewal application of Vedanta Limited for its copper smelter plant at Tuticorin. It directed Vedanta Limited not to resume production operations without formal approval/consent (vide order dated April 12, 2018), and directed the closure of the plant and the disconnection of electricity (vide order dated May 23, 2018). |
| • | The Government of Tamil Nadu also issued an order dated May 28, 2018 directing the TNPCB to permanently close and seal the existing copper smelter at Tuticorin; this was followed by the TNPCB on May 28, 2018. Vedanta Limited filed a composite appeal before the NGT against all the above orders passed by the TNPCB and the Government of Tamil Nadu. In December 2018, NGT set aside the impugned orders and directed the TNPCB to renew the CTO. The order passed by the NGT was challenged by Tamil Nadu State Govt. in Hon’ble Supreme Court. |
| • | The Hon’ble Supreme Court on February 18, 2019 set aside the NGT judgment dated December 15, 2018 on the grounds of maintainability, allowing Vedanta Limited the liberty to approach the High Court of Madras to challenge all the orders collectively, stating that no plea of alternative remedy shall be allowed. |
| • | Based on the said order, Vedanta Limited has filed a writ petition before the Principal Bench of the High Court of Madras and has additionally filed an application seeking interim relief for care and maintenance of the plant. The High Court of Madras vide its judgement dated August 18, 2020 dismissed the writ petition filed by the Company. The Company has approached the Hon’ble Supreme Court and challenged the said High Court of Madras order by way of a SLP to Appeal and also filed an interim relief for care and maintenance of the plant. The matter was then listed on December 2, 2020 before Hon’ble Supreme Court Bench. The Bench after having heard both the sides concluded that at this stage the interim relief in terms of trial run could not be allowed. Further, considering the voluminous nature of documents and pleadings, the matter shall be finally heard on merits. Further, Hon’ble Supreme Court held that the case will be listed once physical hearing resumes in Hon’ble Supreme Court. After a series of computer-generated hearing dates, the matter was taken up on March 15, 2022 and was part heard. The matter was to be further heard on March 22, 2022, however due to reconstitution of the bench the matter was not listed. The Hon’ble Supreme Court has, on May 20, 2022, ordered for the interlocutory application that was filed by Vedanta Limited before the Hon’ble Supreme Court for the maintenance of status quo as on March 15, 2022 consequent to an order passed by the Collector of Tuticorin requiring Vedanta Limited employees to vacate the plant premises to be listed for hearing along with the main matter on the next date of listing. |
| • | Cost of production of aluminium is weighted average cost of production of our Jharsuguda and BALCO aluminium smelters. The cost of production before by-product revenue includes cost of purchased alumina and the cost of captive alumina produced at Lanjigarh. Cost of production net of by-product revenue represents cost of production before by-product revenue, net of revenue earned from the sale of by-products, such as vanadium, which is consistent with the industry practice. The total cash cost before by-product revenue and net of by-product revenue is divided by the total quantity of hot metal produced to determine the cost of production before by-product revenue and net of by-product revenue per ton of aluminium hot metal produced. Hot metal production volumes are used instead of the cast metal production volumes disclosed, elsewhere in this Annual Report, for calculating cost of production. This is because, the hot metal production, which excludes the value-added cost of casting, is the measure generally used in the aluminium metal industry for calculating measures of cost of production. |
| • | In the case of steel, the cost of production after by-product revenue includes the cost of producing hot metal which includes iron bearing raw material comprises of iron ore fines, lumps, pellets and mill scale, Coking coal comprises of hard coking, semi soft coking coal, high fluidity coal, limestone and Dolomite etc. This Cost also includes conversion cost of hot metal into saleable products such as Wire Road, TMT Bar, DI Pipe, Pig iron and billets. The total cost before by-product revenue and net of by-product revenue is divided by total quantity to determine the cost of production before by-product and net of by-product revenue per ton of steel produced. |
| • | Cost of production before by-product revenue and net of by-product revenue is divided by the daily average exchange rate for the period to calculate US dollar cost of production per lb or per ton of metal or per barrel of oil equivalent as reported. |
| • | Cost of production of power for Jharsuguda 600 MW power plant (excluding 274 MW HZL wind power plant, the TSPL 1,980 MW, IPP 300 MW BALCO power plant and the 106.5 MW MALCO’s power plant) includes the cost of coal and other liquid fuels used for generating power and other overhead costs such as operating, maintenance and manpower costs. The total cost is divided by the total net units generated to calculate the cost of production per unit of energy produced. |

| Delaware Law |
Indian Law | |
| Annual and Special Meetings of Shareholders |
||
| Shareholders of a Delaware corporation generally do not have the right to call meetings of shareholders unless that right is granted in the certificate of incorporation or by-laws. However, if a corporation fails to hold its annual meeting within a period of 30 days after the date designated for the annual meeting, or if no date has been designated for the annual meeting, or if no date has been designated for a period of 13 months after its last annual meeting, the Delaware Court of Chancery may order a meeting to be held upon the application of a shareholder. |
While shareholders of a company do not have any right to call for an annual general meeting, shareholders holding one-tenth of the paid-up share capital of the company have a right to request an extraordinary general meeting. However, in the event the company defaults in holding an annual general meeting within 15 months from the date of its last annual general meeting or within 6 months from the end of financial year, whichever is higher, the GoI may order a meeting to be held upon the application of any shareholder. | |
| Quorum Requirements for Meetings of Shareholders |
||
| A Delaware corporation’s certificate of incorporation or bylaws can specify the number of shares which constitute the quorum required to conduct business at a meeting, provided that in no event shall a quorum consist of less than one-third of the shares entitled to vote at a meeting, except that, where a separate vote by a class or series or classes or series is required, a quorum shall consist of no less than one-third of the shares of such class or series or classes or series. |
Our Articles of Association specify that the quorum for the general meeting shall be as provided in the Companies Act, 2013. According to the Companies Act, 2013, quorum for a general meeting is at least 30 shareholders personally present if number of members as on date of meeting is exceeding 5,000 to vote and, in such instances the Indian Companies Act, 2013 supersedes the Articles of Association. | |
| Board of Directors |
||
| A typical certificate of incorporation and bylaws would provide that the number of directors on the board of directors will be fixed from time to time by a vote of the majority of the authorized directors. Under Delaware law, a board of directors can be divided into classes and cumulative voting in the election of directors is only permitted if expressly authorized in a corporation’s certificate of incorporation. | Our Articles of Association provide that unless otherwise determined by the shareholders at a general meeting, the number of directors shall not be less than three or more than 15. The Company may appoint more than 15 directors by seeking the approval of its members by way of a special resolution. Under Indian law, the appointment and removal of directors (other than additional directors) is required to be approved by the shareholders. There is no concept under Indian law as to division of the board of directors into different classes or cumulative voting. | |
| Delaware Law |
Indian Law | |
| Removal of Directors |
||
| Under the Delaware General Corporation Law, a director of a corporation may be removed with the approval of a majority of the outstanding shares then entitled to vote at an election of directors, unless the certificate of incorporation provides otherwise. | Under Indian law, a director of a company, other than a director appointed by the GoI, may be removed by an approval of the members by way of an ordinary resolution, provided that a special notice of the resolution to remove the director is given in accordance with the provisions of the Indian Companies Act, 2013. Under our Articles of Association, any director who has been appointed by any persons pursuant to the provisions of an agreement with us may be removed at any time by such person. | |
| Filling Vacancies on the Board of Directors |
||
| A typical certificate of incorporation and bylaws provide that, subject to the rights of the holders of any preferred stock, any vacancy, whether arising through death, resignation, retirement, disqualification, removal, an increase in the number of directors or any other reason, may be filled by a majority vote of the remaining directors, even if such directors remaining in office constitute less than a quorum, or by the sole remaining director. Any newly elected director usually holds office for the remainder of the full term expiring at the annual meeting of stockholders at which the term of the class of directors to which the newly elected director has been elected expires. | The board of directors has the power to fill a vacancy on the board and any director so appointed shall hold office only so long as the vacating director would have held such office if no vacancy had occurred. The board has also the power to appoint additional director, however, such appointment shall be subject to approval by the shareholders in the immediate next annual general meeting | |

| Interested director transactions are not voidable if (i) the material facts as to the interested director’s relationship or interests are disclosed or are known to the board of directors and the board in good faith authorizes the transaction by the affirmative vote of a majority of the disinterested directors, (ii) the material facts are disclosed or are known to the shareholders entitled to vote on such transaction and the transaction is specifically approved in good faith by vote of the majority of shares entitled to vote on the matter or (iii) the transaction is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee or the shareholders. | Under Indian law, contracts or arrangements in which one or more directors of an Indian company has an interest are not void or voidable because of such interest, provided that certain conditions, such as obtaining the required approval of the board of directors and disclosing the nature of the interest to the board of directors, are satisfied. Subject to a few exceptions, for an interested director transaction not to be voided, (a) the interested director is required to disclose the nature of his concern or interest at a meeting of the board of directors, whether directly or indirectly, is concerned or interested including the Director who is a Promoter, Manager, Chief Executive Officer of anybody corporate; (b) the board of directors is required to grant its consent to the contract or arrangement; (c) the interested director is not permitted to take part in the discussion of, or vote on, the contract or arrangement; and (d) the approval of the members is required by way of resolution. An interested director is not to be counted for the purposes of quorum at the time of any such discussion or vote and if the interested director does vote, the vote shall be void. The contravention of relevant provisions is punishable with fine. Nothing in this section shall apply to any contract or arrangement entered into or to be entered into between two companies or between one or more companies and one or more bodies corporate where any of the directors of the one company or body corporate or two or more of them together holds or hold not more than two percent of the paid-up share capital in the other company or the body corporate. | |
| Cumulative Voting |
||
| Delaware law does not require that a Delaware corporation provide for cumulative voting. However, the certificate of incorporation of a Delaware corporation may provide that shareholders of any class or classes or of any series may vote cumulatively either at all elections or at elections under specified circumstances. | There is no concept of cumulative voting under Indian law. | |
| Shareholder Action Without a Meeting |
||
| Unless otherwise specified in a Delaware corporation’s certificate of incorporation, any action required or permitted to be taken by shareholders at an annual or special meeting may be taken by shareholders without a meeting, without prior notice and without a vote, if consents, in writing, setting forth the action, are signed by shareholders with not less than the minimum number of votes that would be necessary to authorize the action at a meeting. All consents must be dated. No consent is effective unless, within 60 days of the earliest dated consent delivered to the corporation, written consents signed by a sufficient number of holders to take the action are delivered to the corporation. | There is no concept of shareholder action without a meeting under Indian law. | |

| Business Combinations |
||
| With certain exceptions, a merger, consolidation or sale of all or substantially all the assets of a Delaware corporation must be approved by the board of directors and a majority of the outstanding shares entitled to vote thereon. | The sale, lease, or disposal of all or substantially all of the assets of an Indian company must be approved by the board of directors and shareholders holding a majority of the voting share capital of the company. Under the Indian Companies Act, 2013 the merger of two companies is required to be approved by a Court of competent jurisdiction or NCLT and by a three-fourths majority of each class of shareholders and creditors of the company present and voting at the meetings held to approve the merger. | |
| Interested Stockholders |
||
| The Delaware General Corporation Law contains a business combination statute applicable to Delaware public corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date on which such person becomes an interested shareholder. An interested shareholder generally is one which owns or owned 15.0% or more of the target’s outstanding voting shares within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction that resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware public corporation to negotiate the terms of any acquisition transaction with the target’s board of directors. |
Indian law does not prohibit corporate transactions but does require disclosure of related party transactions in the financial statements of the company. Under applicable accounting standards in India, during the time that a related party transaction exists, a company is required to disclose the name of the related parties, describe the relationship between the parties, nature of the transactions and volume of the transactions either as an amount or as an appropriate proportion, the amounts or appropriate proportions of outstanding items pertaining to related parties at the balance sheet date and provisions for doubtful debts due from such parties at that date and the amounts written off or written back in the period in respect of debts due from or to related parties. Transactions undertaken between a company and a person having a substantial interest in the company would qualify as a related party transaction and would be required to be disclosed under applicable accounting standards in India. Under such accounting standards, a party is considered to have a substantial interest in a company if that party owns, directly or indirectly, 20.0% or more of the voting power in the company. | |
| Limitations on Personal Liability of Directors |
||
| A Delaware corporation may include in its certificate of incorporation provisions limiting the personal liability of its directors to the corporation or its shareholders for monetary damages for many types of breach of fiduciary duty. However, these provisions may not limit liability for any breach of the director’s duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, the authorization of unlawful dividends, or unlawful share purchase or redemption, or any transaction from which a director derived an improper personal benefit. Moreover, these provisions would not be likely to bar claims arising under US federal securities laws. | Generally, Indian law provides that directors are not personally liable in respect of contracts of the company. However, where a director acts without the approval or ratification of the company, such director may be personally liable. Directors are also personally liable for breach of trust or misfeasance, both civilly and in some cases criminally. The Companies Act, 2013 of India, contains certain provisions making directors personally liable to discharge certain monetary obligations in their capacity as directors, such as the non-refund of share application monies or excess application monies within the time limit stipulated by the Companies Act, 2013. Similarly, the Companies Act, 2013 provides for civil liability of directors for misstatements in a prospectus issued by the company that has been signed by the directors, including the obligation to pay compensation to any persons subscribing to the shares of the company on the faith of statements made in the prospectus. Directors’ and officers’ liability insurance policies are available in India. However, the permissible coverage under such policies is subject to the same limitations as on the ability of the company to indemnify its directors as described under “- Indemnification of Directors and Officers.” | |
| Indemnification of Directors and Officers |
||
| A Delaware corporation may indemnify a director or officer of the corporation against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in defense of an action, suit or proceeding by reason of his or her position if (i) the director or officer acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and (ii) with respect to any criminal action or proceeding, the director or officer had no reasonable cause to believe his or her conduct was unlawful. | Under Indian law, subject to specified exceptions, any provision, whether contained in the Articles of Association of a company or in any agreement, exempting or indemnifying any director, officer or auditor of the company against any liability in respect of any negligence, default, breach of duty or breach of trust which would by law otherwise attach to such director, officer or auditor, shall be void. However, pursuant to the exceptions permitted under Indian law, our Articles of Association provide for indemnification of any officer or agent against any liability incurred by such person in successfully defending any proceeding, whether civil or criminal, in which such person is acquitted in whole or in part on the grounds that such person had acted honestly and reasonably, or in connection with an application made by an officer or agent to the High Court of the relevant state for relief for reason that he or she has a reason to apprehend that any proceeding may be brought against him in respect of any negligence, default, breach of duty, misfeasance or breach of trust in which relief has been granted by such High Court. | |

| Appraisal Rights |
||
| A shareholder of a Delaware corporation participating in certain major corporate transactions may, under certain circumstances, be entitled to appraisal rights pursuant to which the shareholder may receive cash in the amount of the fair value of the shares held by that shareholder (as determined by a Court) in lieu of the consideration the shareholder would otherwise receive in the transaction. |
There is no concept of appraisal rights under Indian law. | |
| Shareholder Suits |
||
| Class actions and derivative actions generally are available to the shareholders of a Delaware corporation for, among other things, breach of fiduciary duty, corporate waste and actions not taken in accordance with applicable law. In such actions, the court has discretion to permit the winning party to recover attorneys’ fees incurred in connection with such action. | Under the Indian Companies Act, 2013, shareholders holding not less than one tenth of the issued share capital, shareholders representing not less than one tenth of the total number of members or one hundred members, provided that they have paid all calls and other sums due on their shares, have the right to request the NCLT, a statutory body, for an order or injunction as to the taking or not taking of an action by the company on the following grounds of oppression or mismanagement: (a) that the company’s affairs are being conducted in a manner prejudicial to public interest, in a manner oppressive to any member or members or in a manner prejudicial to the interests of the company; and (b) that a material change has taken place in the management or control of the company, whether by a change in the board of directors or management or in the ownership of the company’s shares, and by reason of such change it is likely that the affairs of the company will be conducted in a manner prejudicial to public interest or in a manner prejudicial to the interests of the company. | |
| Inspection of Books and Records |
||
| All shareholders of a Delaware corporation have the right, upon written demand under oath stating the purpose thereof, to inspect or obtain copies of the corporation’s shares ledger and its other books and records for any proper purpose. | Pursuant to our Articles of Association, our Board of directors has the authority to determine whether and to what extent and at what times and places and under what conditions or regulations our books are open to the inspection of the shareholders. Further, no shareholder of the company has the right to inspect any record of the company except as conferred under law or authorized by the board of directors. The books containing the minutes of the proceedings of any general meetings of the shareholders are required to be kept at the registered office of the company and such materials are to be opened for inspection by any shareholder, without charge, subject to reasonable restrictions which may be imposed by a company’s articles or in its general meeting. If an inspection is refused, the company and every officer of the company in default will be punishable with a fine. Under Indian law, the audited financial statements for the relevant financial year, the directors’ report and the auditors’ report are required to be provided to the shareholders before the annual general meeting. | |

| Amendment to Charter |
||
| Amendments to the certificate of incorporation of a Delaware corporation require the affirmative vote of the holders of a majority of the outstanding shares entitled to vote thereon or such greater vote as is provided for in the certificate of incorporation; a provision in the certificate of incorporation requiring the vote of a greater number or proportion of the directors or of the holders of any class of shares than is required by Delaware corporate law may not be amended, altered or repealed except by such greater vote. | Under Indian Law, subject to certain specified amendments that require the additional approval of the central government, a company may make amendments to its articles with the approval of shareholders holding not less than 75.0% of the shares of the company. | |
| Distributions and Dividends; Repurchases and Redemptions |
||
| Delaware law permits a corporation to declare and pay dividends out of statutory surplus or, if there is no surplus, out of net profits for fiscal year in which the dividend is declared and/or for the preceding fiscal year as long as the amount of capital of the corporation following the declaration and payment of the dividend is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Under Delaware law, any corporation may purchase, redeem, receive, take or otherwise acquire, own and hold, sell, lend, exchange, transfer or otherwise dispose of, pledge, use and otherwise deal in and with its own shares, except that generally it may not purchase or redeem those shares if the capital of the corporation is impaired at the time or would become impaired as a result of the redemption. A corporation may, however, purchase or redeem capital shares that are entitled upon any distribution of its assets, whether by dividend or in liquidation, to a preference over another class or series of its shares if the shares will be retired upon their acquisition and the capital of the corporation is reduced. |
Under Indian law no dividend shall be declared or paid by a company for any financial year except out of the profits of the company for that year arrived at after providing for depreciation in accordance with the provisions of sub-section (2), or out of the profits of the company for any previous financial year or years arrived at after providing for depreciation in accordance with the provisions of that sub-section and remaining undistributed, or out of both provided that in computing profits any amount representing unrealized gains, notional gains or revaluation of assets and any change in carrying amount of an asset or of a liability on measurement of the asset or the liability at fair value shall be excluded. If the profits for a year are insufficient, the dividend for that year may be declared out of the accumulated profits earned in previous years and transferred to reserves, subject to the following conditions:(i) the rate of dividend declared shall not exceed the average of the rates at which dividend was declared by it in the 3 years immediately preceding that year. (ii) the total amount to be drawn from the accumulated profits from previous years and transferred to the reserves may not exceed an amount equivalent to one tenth of the paid-up capital and free reserves(iii) the amount so drawn shall first be utilized to set off the losses incurred in the financial year in which dividend is declared before any dividend in respect of the equity shares is declared. (iv) the balance of reserves after such withdrawal shall not fall below fifteen percent of its paid up share capital as appears in the latest audited financial statement. v) no company shall declare dividend unless previous losses and depreciation not provided in previous year or years are set off against profit of the company of the current year. Shareholders have a right to claim a dividend, after such dividend has been declared by the company at a general meeting. Shareholders also have a right to claim the interim dividends, which may be declared only pursuant to a resolution of the company’s board of directors provided that in the event the company has incurred loss during the current financial year up to the end of the quarter immediately preceding the date of declaration of an interim dividend, then such interim dividend shall not be declared at a rate higher than the average dividends declared by the company during the immediately preceding 3 financial years. Dividends may be paid in cash or by cheque or warrant or in any electronic mode to the shareholder. Where a dividend has been declared by a company but has not been paid within 30 days from the date of declaration to any shareholder entitled to the payment of such dividend, a penalty can be imposed on a director who is knowingly a party to such default. | |

Description of the Matter |
As discussed in Notes 3(I) and 14 to the consolidated financial statements, the Group performs impairment assessments for assets where there are indicators of impairment or reversal of impairment. As part of that assessment, whenever such indicators exist, the Group determines the recoverable amount based on the higher of the Value in Use (VIU) or Fair Value Less Cost of Disposal (FVLCD) for each of the cash generating units (CGU), considering different internal and external factors in accordance with IAS 36 – Impairment of Assets. During the year, the Group determined that there were indicators of impairment at the Tuticorin Plant CGU, within the Copper segment (refer note 3(c)I(iii)); and indicators of impairment reversal for the Krishna Godavari Block CGU and Rajasthan Block CGU within the Oil and Gas segment (refer to notes 3(c)I(i) and 3(c)I(vii)). The Group recognised a reversal of impairment of ₹ Auditing the Group’s impairment assessments is complex due to the significant estimation and judgement required in determining the recoverable amounts. The Group’s methodologies for estimating the recoverable amounts involve significant assumptions, such as future commodity prices, estimates of oil reserves, future production volumes, discount rates and future capital and operating expenditures. These assumptions are forward-looking and could be affected by future economic and market conditions, as well as certain regulatory uncertainties, as described in notes 3(c)I(iii), 3(c)I(i) and 3(c)I(vii). |
How We Addressed the Matter in Our Audit |
We obtained an understanding, evaluated the design and tested the operating effectiveness of certain internal controls over the Group’s impairment assessment process, including controls over the Group’s assessment of indicators of impairment and controls over the determination of significant assumptions such as future commodity prices, oil reserves and future production volumes, discount rates and future capital and operating expenditures. To test the significant assumptions used for the determination of the recoverable value of the CGUs, our audit procedures included, among others, comparison of future commodity prices with the published commodity price and research reports from external parties, comparison of future capital and operating expenditures and oil reserves to the Group’s latest approved long-term budgets and comparison of management’s estimates of future production volumes to estimates prepared by an external expert engaged by management We involved our valuation specialists to assist us in evaluating the valuation methodologies used, the discount rates and future commodity prices applied to calculate the recoverable amount. With the assistance of our valuation specialists, we performed sensitivity analyses to evaluate the significant assumptions used. With respect to the regulatory uncertainties, we assessed management’s assumptions regarding these through inspection of external legal opinions obtained by us and inquired of the Group’s inhouse legal counsel to evaluate the basis of their conclusions. We also assessed the adequacy of the Group’s disclosures in relation to these matters. |
Description of the Matter |
As described in Note 3(c)I(ii) to the consolidated financial statements, the Group has recognised Minimum Alternate Tax (MAT) credits within deferred tax assets totaling ₹ ₹ As described in Note 9, ESL Steel Limited, a of the subsidiary of the Group, has recognized deferred tax assets of ₹ ₹ Auditing the Group’s assessment of recognition and recoverability of these deferred tax assets is complex and dependent on the generation of future taxable income. Significant judgment and estimation are required to assess the sufficiency of future taxable income and likelihood of the realization of these assets, in particular whether there will be taxable profits in future periods that support the recognition of these assets. Predicting future taxable income is dependent on assumptions and judgments regarding, among other things, future commodity prices, production volumes and capital and operating expenditures. | |
How We Addressed the Matter in Our Audit |
We obtained an understanding, evaluated the design and tested the operating effectiveness of certain internal controls over the estimation of probable future taxable income relating to the recoverability of deferred taxes assets, including controls related to the determination of assumptions used in the preparation and review of the business plan, budget, and analysis of forecasted future taxable income prepared by the Group. To evaluate the future projections of taxable income estimated by management, our procedures included, amongst others, evaluating, with the assistance of valuation specialists, the future cash flow projections, including comparison of forecasts considered in the previous year with the actual performance of the current year and the consistency of those projections with the projections used in other areas of estimation such as those described above for the ‘Impairment assessment of the Krishna Godavari Block, Rajasthan Block and Tuticorin Plant CGUs’. We compared the budgeted forecasts included in the projections to the budget approved by the Board of Directors. We obtained management’s sensitivity analyses over the key assumptions to assess their impact on the forecasts of the future taxable income. We evaluated the adequacy of the disclosures made by the Group on the expected recoverability of the deferred tax assets. | |
Description of the Matter |
As described in Note 3(c)I(iv) to the consolidated financial statements, the Production Sharing Contract (PSC) for the Rajasthan Block (RJ), which was valid until May 14, 2020, was extended, initially for a period of three months and subsequently through a series of extensions up to August 14, 2022, subject to compliance with certain conditions, one of which relates to settlement of demands raised by the Government of India through the Directorate General of Hydrocarbons (DGH) with respect to the government’s share of profit petroleum for RJ. The Group recognizes a liability for those demands for which it is probable that a liability has been incurred as of March 31, 2022 and the amount is reasonably estimable. Matters where a liability is assessed as possible, or a reasonable estimate cannot be made are disclosed as contingencies in the financial statements in accordance with IAS 37 - Provisions, Contingent Liabilities and Contingent Assets. The Group, after considering the underlying facts and circumstances, including court rulings, have considered the PSC extension to be reasonably certain and disclosed the matter, including the related demands, as a contingency in the consolidated financial statements. Auditing management’s determination of whether a liability in respect of the aforesaid PSC extension matter is probable and reasonably estimable, possible or remote, is highly subjective and requires significant judgment considering the time period involved in the resolution of the matters, since these disputes include the government as the counterparty and the complexity of the matters involved with limited precedents. | |
How We Addressed the Matter in Our Audit |
We obtained an understanding, evaluated the design of and tested certain internal controls of the Group for assessing the completeness, valuation, presentation and disclosure of the contingencies. We evaluated the Group’s analysis of the probability of a liability related to the demands arising on the PSC extension matter through inspection of relevant documentation and correspondence, including High Court rulings and responses sent to DGH. We obtained written legal assessments of the demands from the Group’s external legal counsel and made enquiries of the Group’s internal and external legal counsel to confirm our understanding of those assessments. We obtained written representations from executives of the Group regarding the accounting and disclosures made in the consolidated financial statements, relating to the demands. We also evaluated the adequacy of the Group’s disclosures in relation to these matters. | |

ESL had filed application for renewal of Consent to Operate (CTO) on August 24, 2017 for the period of five years which was denied by Jharkhand State Pollution Control Board (‘JSPCB’) on August 23, 2018, as JSPCB awaited response from MoEFCC over a 2012 show-cause notice. After a personal hearing towards the show cause notice, the MoEFCC also revoked the EC on September 20, 2018. The Hon’ble High Court of Jharkhand granted stay against both the above orders and allowed the continuous running of the plant operations under regulatory supervision of the JSPCB. The Jharkhand High Court on September 16, 2020 passed an order vacating the interim stay in place beyond September 23, 2020 while listing the matter for final hearing. ESL urgently filed a petition in the Supreme Court, and on September 22, 2020, ESL was granted permission to run the plant till further orders. |

| * | Refer N ote 35(b) |
| • | Investments traded in active markets are determined by reference to quotes from the financial institutions; for example: Net asset value (NAV) for investments in mutual funds declared by mutual fund house. For other listed securities traded in markets which are not active, the quoted price is used wherever the pricing mechanism is same as for other marketable securities traded in active markets. Other current investments are valued by referring to market inputs including quotes, trades, poll, primary issuances for securities and /or underlying securities issued by the same or similar issuer for similar maturities and movement in benchmark security, etc. |
| • | Financial assets forming part of cash and cash equivalents (including restricted cash and cash equivalents), bank deposits, financial liabilities forming part of trade and other payables, acceptances and short-term borrowings being carried at amortised cost. The fair value approximate their carrying amounts largely due to the short-term maturities of these instruments. |
| • | Non-current fixed-rate and variable-rate borrowings: Fair value has been determined by the Group based on parameters such as interest rates, specific country risk factors, and the risk characteristics of the financed project. |
| • | Quoted financial asset investments: Fair value is derived from quoted market prices in active markets. |
| • | Unquoted financial asset investments: Fair value of unquoted securities are determined by reference to discounted cash flows model. |
| • | Derivative financial assets/liabilities: The Group executes derivative financial instruments with various counterparties. Interest rate swaps, foreign exchange forward contracts and commodity forward contracts are valued using valuation techniques, which employ the use of market observable inputs. The most frequently applied valuation techniques by the Group include forward pricing and swap models using present value calculations. The models incorporate various inputs including the foreign exchange spot and forward rates, yield curves of the respective currencies, currency basis spreads between the respective currencies, interest rate curves and forward rate curves of the underlying commodity. Commodity contracts are valued using the forward LME rates of commodities actively traded on the listed metal exchange, i.e., London Metal Exchange, United Kingdom (UK). |
| • | Other non-current financial liabilities: Fair value is calculated using a discounted cash flow model with market assumptions, unless the carrying value is considered to approximate to fair value. |
| • | improve financial risk awareness and risk transparency |
| • | identify, control and monitor key risks |
| • | identify risk accumulations |
| • | provide management with reliable information on the Group’s risk situation |
| • | improve financial returns |
| • | economic hedging of prices realised on commodity contracts |
| • | cash flow hedging of revenues, forecasted highly probable transactions |

This Code must be read in letter as well as in spirit.
Applicability
| | This Code applies to all directors, officers, and employees of the Company and its subsidiaries (which, unless the context otherwise requires, are collectively referred to in this code as the Company). This code is also applicable to vendors, service providers and third parties dealing with Vedanta and when dealing on Vedantas behalf. |
| | The Code also covers the Duties of Independent Directors as annexed in Annexure-1 to this Code and as prescribed in Schedule IV to the Companies Act, 2013. |
Objectives
The Code aims to achieve the following objectives:
| | Establishing the rules and principles to be adhered to by employees to ensure ethical business conduct, demonstrating financial and operational excellence and making a positive contribution to our community and society. |
| | Providing directives for compliance with applicable governmental laws, rules, and regulations; |

If you feel uncomfortable about a situation or have any doubts about whether it is consistent with the Companys ethical standards, seek help. We encourage you to contact your supervisor for help first. |
| | If your supervisor cannot answer your question or if you do not feel comfortable contacting your supervisor, contact the Secretarial/Legal Department.

Anti-Corruption & Bribery
| | Bribery is the offer, promise, giving, demanding or acceptance of an advantage as an inducement for an action which is illegal, unethical or a breach of trust. |
| | Corruption is the misuse of public office or a business position for private gain. Bribery of Public Officials or agents, whether public or private, is prohibited and individuals who engage in bribery face a real risk of imprisonment. Bribery of Public Officials or agents, whether public or private is prohibited under the Prevention of Corruption Act, 1988. |
| | The Foreign Corrupt Practices Act (the FCPA) prohibits the Company, its Employees and Service Providers from offering or giving money or any other item of value to win or retain business or to influence any act or decision of any Public Official, political party, candidate for political office or official of a public international organization. FCPA prohibits the payment of bribes, kickback, or other inducements to foreign officials. This prohibition also extends to payments to a Service Provider if there is reason to believe that the payment will be used indirectly for a prohibited payment to foreign officials. Violation of the FCPA is a crime that can result in severe fines and criminal penalties, as well as disciplinary action by the Company, up to and including termination of employment. |
| | The UK Bribery Act (UKBA) also prohibits company and its associated persons from offering, promising, or giving any financial or other advantage to bring about the improper performance by another person of a relevant function or activity, to influence a Public Official in performance of his or her official functions with an intention to obtain or retain business or an advantage in the conduct of business. Further, receipt of bribe is also covered by the act and is an offence under it. The UKBA prohibits payment and receipt of bribes directly or indirectly through associated person. For the purpose of this clause associated person shall mean Agents, intermediaries, consultants, freight forwarders, contractors, advisers, suppliers, subsidiaries, third party service providers and other business partners who provide services to Company. |
| | We must endeavour to comply with all applicable Anti-Corruption Legislations that the Company is subject to, including the Prevention of Corruption Act, 1988 which criminalizes bribes accepted by Public Servants, the UK Bribery Act, and the U.S. Foreign Corrupt Practices Act. |
| | Facilitation payments are payments made to Public Officials to speed up an administrative process, the outcome of which is pre-determined. Facilitation payments are also considered akin to acts of Bribery and Corruption. The Company prohibits making any kind of facilitation payments in the course of business. |
| | The Company and its employees shall not offer or provide an undue monetary or other benefit to any person or persons, including public officials, customers, or employees, in violation of laws and the officials legal duties in order to receive any improper advantage or to obtain or retain business. |
| | Employees must never seek or accept any payment, personal benefits or favors through their position with the Company, which might influence or appear to influence any business decisions or transactions. |
| | Employees and service providers must not use subcontracts, purchase orders, consulting agreements, etc., as means of channeling payments to Public Officials, to employees of business partners or to their relatives / business associates or others. |
5
| | Always be truthful, accurate, cooperative, and courteous when dealing with government or regulatory agency officials in the course of business. Notify and seek advice from your Supervisor or the Legal/Secretarial team if you receive a non-routine request from a government or regulatory agency official. Stand firm against possible corruption. Never offer anything of value to obtain an actual or perceived improper advantage. |
| | The Company follows a zero-tolerance approach towards bribery or any corrupt act. |

10
Conflict of Interest
| | A conflict of interest can occur when an employees personal interest interferes, or appears to interfere, with the interests of the Company as a whole. |
| | An employees employment obligation is to the Company. The Companys employees should not enter into any situation in which their personal or financial interests may conflict with those of the Company or influence their ability to act in the interest of the Company. |
| | Business decisions and actions must be based on the best interests of the Company, and your work must be performed objectively and effectively. |
| | Relationships with business partners, customers, competitors, or regulators should not be allowed to affect our independent and sound judgment on behalf of the Company. |
| | Certain situations which may present a conflict of interest are as follows: |
| | Outside Employment. No employee should be employed by, serve as a director of, or receive payments for services to any other company, especially a customer, supplier, distributor, or competitor of the Company without the advance approval of the Chief Human Resource Officer (CHRO) of the Company. Any outside activity must be strictly separated from employment by the Company and should not harm the Companys interests, the business of the Company or job performance at the Company. |
| | Financial Interests. Employees must not allow their investments to influence, or appear to influence, their independent judgment on behalf of the Company. The appearance of a conflict of interest is most likely to arise if an employee has an investment in a competitor, supplier, customer or distributor and his decision may have a business impact on this outside party. |
| | Loans or Other Financial Transactions. No employee should obtain loans or guarantees of personal obligations from, or enter into any other personal financial transaction with, any company that is a customer, supplier, or competitor of the Company. This does not prohibit arms-length transactions with banks, brokerage firms or other financial institutions. |
| | Service on Boards and Committees. No employee should serve on a board of directors or trustees or on a committee of any entity (whether profit or not-for-profit) whose interests reasonably would be expected to conflict with those of the Company. Any such service would require the prior approval of the Chief Human Resource Officer (CHRO) of the Company. |
| | Personal or Professional Interests of Family Members. The associations of family members with any business partners, customers, competitors of the Company, may also give rise to the conflicts of interest described above because they may influence an employees objectivity in making decisions on behalf of the Company. |
| | The Company requires that employees disclose any situations that reasonably would be expected to give rise to a conflict of interest. If you suspect that you have a conflict of interest, or something that others could reasonably perceive as a conflict of interest, you must report it to your supervisor or the Secretarial / Legal Department. |
| | Any personal relationships within the workplace with any existing employees or with potential candidates for recruitment must be reported to HR. |
Protection & Use of Company Assets
| | Employees should protect the Companys assets and ensure their efficient use for legitimate business purposes only. Theft, carelessness, and waste have a direct impact on the Companys profitability. |
11
| | The use of Company funds or assets, whether or not for personal gain, for any improper or unlawful purpose is prohibited. |
| | To ensure the protection and proper use of the Companys assets, each employee should: |
| | Exercise reasonable care to prevent theft, damage, or misuse of Company property, including the electronic and technology systems of the Company. |
| | Report the actual or suspected theft, damage, or misuse of Company property to a supervisor. |
| | Use the assets of the Company including the Companys telephone system, other electronic communication services, written materials, and other property primarily for business-related purposes. |
| | Safeguard all electronic programs, data, communications, and written materials from inadvertent access by others. Any inappropriate use of the Companys electronic assets may inadvertently expose the Company to cybersecurity breaches and loss or theft of the data. |
| | Use Company property only for legitimate business purposes, as authorized in connection with your job responsibilities. |
| | Employees should be aware that Company property includes all written communications and data residing on and communications transmitted through the Companys electronic or telephonic systems. |
| | The Company has the right and the obligation to assess all data and communication transmissions using the Companys Assets and if required, to disclose the same to law enforcement and regulatory authorities. |

Introduction
Antitrust Guidance Notes (Guidance Notes) contains the guidance on the Vedanta Groups (the Group) commitment for antitrust law compliance. The purpose of these Guidance Notes is to set out the Groups commitment for compliance with antitrust law and to provide basic guidance to all the Groups employees, wherever located, with regard to antitrust law and to assist them in complying with it. As the Group is operating in a highly competitive environment where respective antitrust laws play an increasingly important role, the Group, hereby would like to emphasize its objective of integrity and compliance towards antitrust laws. The Group is committed to the preservation of vigorous, healthy, and fair competition and to complying with relevant antitrust legislation.
Antitrust laws guard against anti-competitive agreements and the abuse of dominant power. Noncompliance with applicable national antitrust laws can have unfavourable consequences for the financial condition, reputation, and viability of the group.
The Groups employees and business partners (e.g., suppliers, consultants, advisers, or any other form of service providers) should feel personally responsible for the strict application of the Guidance Notes throughout the Group at all times and in all countries where the Group operates, especially with the nature and seriousness of the risks likely to result from any infringement to antitrust legislation.
Companies that infringe antitrust law can face significant fines. For instance, the European Commission and Competition Commission of India can impose fines of up to 10% of the consolidated total turnover of the Group. Companies may be sued for damages by those who can demonstrate that they have sustained losses as a result of anti-competitive practices. Any contractual provision which infringes antitrust laws is generally void and cannot be enforced in the courts. Moreover, the entire contract could also be invalidated in certain circumstances and jurisdictions. Apart from monetary risk, infringement of antitrust laws is more and more perceived by the stakeholders as unethical behaviour, which can seriously impact the image and reputation of the group, and also affect its ability to convince that it observes highest standards of corporate governance. The antitrust authorities have in recent times also held directors, senior management, and other officials of companies liable for violating antitrust laws when they found that employees have connived with the company to commit anti-competitive activities.
Considering the high risk involved in non-compliance and high standards of commitment for antitrust compliance as stated in the Guidance Notes of the Group, compliance with antitrust laws by the Group implies compliance by all employees with highest standard. However, the Guidance Note is specifically targeted at those employees who are or may become involved with antitrust law in the course of their professional duty. It is compulsory for all employees to read and understand the Guidance Notes carefully and ensure to comply fully with antitrust laws. The Guidance Notes are aimed at raising all employees level of awareness of antitrust rules but cannot answer all questions. That is why it is suggested to seek advice from the respective Compliance Officer (Compliance Officer) of the Group company (Company), every time in need of any further information.
Overview of Antitrust laws
Despite a lack of uniformity, especially when it comes to procedural aspects, there is a growing trend towards harmonization of antitrust legislation in all countries where the market economy and free competition have been adopted as the best model for economic development.
Antitrust law generally is based on three underlying concepts:
| | the prohibition of anticompetitive agreements and concerted practices; |
| | the prohibition of abuse of a dominant position or of substantial market power; and |
27
| | the assessment of acquisitions and joint ventures to prevent the creation of dominant positions or the reduction of competition These Guidance Notes provides comprehensive guidance on above-mentioned concepts, however, these are not exhaustive and situations which are not covered herein under may also arise. Therefore, any doubt should immediately be directed to the respective Compliance Officer of the Company. |
| 1. | Anti-Competitive Agreements |
For antitrust law purposes, the term agreement has a very wide meaning and includes all kinds of collusive arrangements and understandings between two (or more) competitors, written and/or unwritten. Antitrust law prohibits agreements or concerted practices between market players that have as their object or effect to restrict competition. The prohibition of restrictive agreements must be interpreted widely. The concept of agreement in antitrust law includes formal as well as informal agreements, written and oral agreements, explicit or implicit deals or understandings. The actual form of the agreement is irrelevant, as soon as there is a meeting of the minds, an agreement exists.
A concerted practice is a form of coordination between market players which, without having reached the stage where an agreement has been concluded, knowingly substitute practical cooperation between them for the risks of competition. Especially exchanges of confidential information between competitors are often found to qualify as a concerted practice.
As soon as an agreement has the object of restricting competition, antitrust law applies. The agreement does not need to be implemented first in order to be prohibited. If an agreement was reached, and the parties would individually decide not to implement the agreement, they could still be fined for their agreement. The opposite also applies. If the parties intent were not at all aimed at restricting competition, but the agreement would have a restrictive effect of competition, the agreement would equally be prohibited, and the companies might be punished.
Any contact between competitors may give rise to concern from an antitrust law perspective. Antitrust authorities will always be suspicious about the real intentions for competitors to meet. As a result, all employees should be careful when meeting competitors, also on informal occasions, and wonder whether the purposes for meeting are allowed from an antitrust law perspective. If there is any doubt about this issue, employee should contact to the respective Compliance Officer of the Company.
| 1.1 | Relationship with Competitors |
Any agreement to maintain prices, restrict supply to raise prices, allocate market amongst industry players (whether oral or written) formal or informal is anti-competitive and all employees must refrain from conniving in any such activities. A brief introduction is given to all these types of agreements for general understanding, any doubt/query regarding these practices must be shared with concerned Compliance Officer of the Company.
| 1.1.1 | Price fixing |
In all antitrust law regimes, it is illegal for competitors to agree, whether directly or indirectly (for example through distributors), the price level at which their products will be sold to third parties. Agreements or understandings that affect prices indirectly, such as on rebates or discounts, pricing methods, costs, and terms of payment, are also considered illegal under antitrust law.
| 1.1.2 | Division of territories/market sharing & allocation of customers |
It is illegal under antitrust law for competitors to allocate territories to each other and/or to agree not to compete in such territories. Market sharing or market division agreements may be either to share markets geographically or in respect of consumers or particular categories of consumers or types of goods or services in any other way. Competitors are not allowed to agree to divide customers between them in the markets in which they compete, or where they could be expected to compete.
28
| 1.1.3 | Group boycott |
It is illegal for competitors to agree to boycott a particular customer or supplier or class of customers or suppliers. Boycott here means any concerted action or agreement between two or more competitors not to sell to or buy from a particular customer or supplier, or class thereof. This type of decision can be also taken by a trade association (Trade Association) while adopting an anti-competitive decision against any particular or class of member or non-member.
Although the Company is free in general to decide not to do business with a supplier, customer or competitor, these decisions carry antitrust risks when they are made jointly by two or more companies. Employees should avoid the following types of agreements, which may be viewed as illegal boycotts:
| | An agreement among competitors not to do business with particular suppliers or customers. |
| | An agreement among certain competitors not to collaborate or do business with other competitors. |
| | An agreement to the request of two or more customers, or two or more suppliers, not to do business with competitors of the companies making the request. |
A boycott can be based on an absolute refusal to do business with the targeted companies, or on a willingness to do business with them only on certain conditions. Some agreements of this type can be legal, but employees should not enter or discuss any of these agreements without first consulting the Compliance Officer of the Company.
| 1.1.4 | Limitation of production |
Agreements that limit or control production, supply, markets, technical development investment or provision of services are also considered to be anticompetitive. It is illegal for competing companies to agree to stop production, or to limit this to a certain level, rather than allowing normal competitive forces to determine their independent production decisions.
| 1.1.5 | Cartelization & Bid rigging |
Cartels are agreements among competitors to fix prices, restrict output, and allocate markets, rig bids and so on. All cartels are illegal, whether the agreement is written or oral, expressly made, or implied. Cartels are the most serious form of antitrust violation. Participation in a cartel can lead to severe penalties, including imprisonment of the employees involved.
Agreements or understandings between competitors regarding prices or terms and conditions to be submitted in response to a bid request are generally prohibited. This includes agreeing not to bid. Generally, there are two common forms of bid-rigging, one in which firms agree to submit common bids and the other where bids are submitted in such a way that each firm wins an agreed number or value of contacts.
| 1.1.6 | Joint purchasing |
Joint purchasing agreements between individual competitors may restrict competition and therefore be prohibited when they limit the parties freedom and/or prevent other suppliers from supplying them to a substantial extent. Moreover, collective purchasing agreements may lead to a substantial purchasing power, which may be interpreted as a collective dominant position of the joint buyers.
29
| 1.1.7 | Joint commercialization |
Agreements between competitors to jointly sell, distribute or promote their products may raise antitrust law concerns where such agreements limit the individual participants in their freedom to determine their own commercial policy and to advertise individually.
| 1.1.8 | Exchange of information |
In general, it is illegal for competing companies to exchange information which may influence the independent determination of their individual commercial policy, such as information regarding sales quantities, prices, cost structure, discounts and other trading conditions, or information relating to their individual customers and/or suppliers.
| 1.1.9 | Site visits at competitors business |
Site visits by or to competitors run the risk of violating antitrust laws. They should be kept to a minimum and limited to health, safety, environmental and similar operational initiatives and should not result in disclosing or obtaining commercially sensitive information. If competitor personnel discuss commercially sensitive information or ask questions about commercially sensitive information, bring the conversation to an end, and report the incident to Compliance Officer of the Company.
| Guidance Note: Dos and Donts with Competitors
Always
Avoid contact with competitors unless having a legitimate reason for it
Maintain the record of purposes of any meetings with competitors.
Avoid any discussion regarding confidential information or business secrets with competitors
If a competitor starts discussing any of the items listed under Do Not below, always mention that you cannot discuss such matters, terminate the conversation, keep an accurate file note of this and of what was said, and inform Legal and compliance team of your company.
Remember that a competitor is not a legitimate source of competitive intelligence.
Maintain Vedantas independence of judgement in pricing, marketing, and selling of any product. Avoid any action which could imply any coordination with competitors
Never

Discuss or agree to restrictions concerning markets (by location or customer) or marketing schedules
Discuss or agree on joint action designed to fix or manipulate the evolution of market shares artificially
Discuss or fix quotas on output or sales (limitation of or agreement on capacities for example)
Discuss or agree to the boycotting of any customers, competitors, or suppliers
Discuss or agree to limit or control any investment or technical development
Receive from a customer, detailed information about a competitors offer/bid unless the structure of the bidding process and information is open and accessible to all participants

30
|
Use a trade publication or a journalist as an indirect means of passing commercially sensitive information to competitors.
Allow access to, seek access from or discuss confidential or other unpublished business information (such as prices; surcharges; costs of production or distribution; profitability; strategy, business, and marketing plans; product development plans; information on customers). |
| 1.2 | Relations with suppliers & distributors |
Unlike agreements with competitors, many agreements with customers/suppliers are necessary and entirely appropriate in the course of day-to-day business. Vertical agreements are agreements between persons at different levels of the production chain such as an agreement between a manufacturer and a distributor. Any agreement amongst enterprises or persons at different stages or levels of the production chain in different markets, in respect of production, supply, distribution, storage, sale or price of, or trade in goods or provision of services, including tie-in arrangement, exclusive supply agreement, exclusive distribution agreement, refusal to deal, resale price maintenance, may be an agreement in contravention of antitrust law if such agreement causes or is likely to cause an appreciable adverse effect on competition in a relevant market.
| 1.2.1 | Tie-in agreement |
Tie-in agreements have been defined as including any agreement requiring a purchaser of goods (called tying product), as a condition of such purchase, to purchase some other goods (called tied product). Generally, employee should not enter into commercial relations conditional upon the acceptance of unrelated additional services, without proper economic justification.
| 1.2.2 | Exclusive supply agreement |
Any agreement restricting in any manner, the purchase from acquiring or otherwise dealing in any good other than those of the seller or any other person may raise antitrust concerns. Exclusive supply dealing agreements may be anti-competitive if they block or create barriers to entry by not permitting other manufacturers to enter the market.
| 1.2.3 | Exclusive distribution agreement |
Any agreement or limit, restrict or otherwise withhold the output or supply of any goods or allocate any area or market for the disposal or sale of goods may create antitrust law issue fall within the category of exclusive distribution agreements. Normally, unsolicited/passive sales by exclusive distributor out of their assigned territory should not be prohibited.
| 1.2.4 | Resale price agreements |
Resale price of maintenance includes an agreement to sell goods on condition that the prices to be charged on the resale by the purchaser shall be the prices stipulated by the seller unless it is clearly stated that prices lower than those prices may be charged. The use of threats, intimidation, warnings, monitoring penalties, delay, or suspension of deliveries as a means of fixing the resale price should not adopted.
| 1.2.5 | One-sided agreements |
Agreements entered by the Company where it has superior bargaining power and is able to dictate terms that are overwhelmingly one-sided are considered to be as anti-competitive.
31
| Guidance Note: Dos and Donts with suppliers & customers
Always
Consider recommending a resale price (it should be unilaterally suggested with no effect of a fixed or minimum price as a result of pressure or incentives).
Justify the objective purpose of choosing exclusive distribution as your sales method.
Sell two products together as a package, only if the customer can also get them separately.
Never
Fix the resale price/ profit margin of a product with your distributor.
Prevent your distributor from reselling your product in a given territory.
Prohibit unsolicited/passive sales by exclusive distributors out of their assigned territory.
Execute exclusive agreements (to buy, sell or limit the territory) of a long duration (to be determined based on local legislation and subject to circumstantial analysis) when you have a relatively large market share.
Make entering into commercial relations conditional upon the acceptance of unrelated additional services, without justification.
Directly or indirectly attempt to obtain information about competitors, from your customers or suppliers.
Obtain competitors information on their current or future price, profit margins or costs, bids, market share, distribution practices, terms of sales, specific customers, or vendors.
Act in a manner that unfairly favors or benefits one customer over another.
Do not receive from a supplier detailed information about its offer to a competitor of the Company.
Require from your customers to purchase one (less desirable) product in order to obtain another (more desirable) product.
Use one-sided clause in the agreements |
| 1.3 | Behaviour at trade associations meetings |
Various companies under the Group are members of many trade associations. These associations can be effective in gathering and disseminating appropriate information as well as in representing the industry to the public, government officials and agencies.
It is perfectly legitimate for employees to participate in trade associations, such activities are not allowed to go beyond such legitimate purpose and notably should not be used as a forum for illegal collusion between competitors, for example by facilitating price fixing, market, and customer allocation arrangements.
Any decisions of associations of companies which have the object or effect to restrict competition are equally prohibited. Antitrust authorities are normally suspicious about such official meetings with competitors. In order to deal with those suspicions, Trade Association should have a competition compliance policy which it strictly adheres to.
32
| Guidance Note: Dos and Donts at trade associations meeting
Always
Stay SOLID if discussions stray into risk areas:
State that you cannot discuss such matters
Object and if meeting is formal, ask for your objection to be minuted
Leave meeting if discussion continues and if meeting is formal, ask for your departure to be minuted
Inform the law department of the discussion
Document the meeting, discussions, and your response
Prior approval should be taken before joining any trade association and before accepting any decision making position in such organization.
An agenda should be circulated well in advance of any meeting and that agenda should not have any anti-competitive issues to be discussed and that agenda is strictly complied with.
Minutes should be recorded and distributed.
Keep distance from any decision (to be) taken by the trade association which may violate antitrust laws. If it continues, leave the meeting (do not accept any documentation) and make sure that your action is recorded
Same principles should be applied in discussions outside the formal trade association meeting (e.g., during lunches or dinners).
Carefully share non-commercially sensitive information about a customer or supplier, such as its credit rating or health & safety record. However, Vedanta must unilaterally decide whether to deal with such a customer/supplier;
Attend only meetings of legitimate trade and professional associations held for proper business or professional purposes.
Never
Participate in trade association gatherings where there is exchange of Commercially Sensitive Information.
Issue advice to the members on any Commercially Sensitive Issues, such as price, technology, and cost factors.
Follow any decision taken by a trade association which may infringe on antitrust laws
Agree, or even discuss, with a competitor to submit a complementary bid (i.e., a bid that does not fulfil requirements of a tender);
Agree to restrict or increase production, including levels of production, manufacturing processes and/or supply of services;
Share technological solutions for specific projects / purchasing/sales strategy, including whether to purchase/sell products or systems from a particular supplier/to a particular customer, or at which conditions;
Agree to impose a collective boycott of a supplier or customer or a competitor without a legitimate reason.
Commercially Sensitive Information is information that can influence a commercial decision or strategy of the Group or its competitor, and includes information about past, current or future:
Pricing elements (e.g., discounts, calculation methods), planned price changes; |
33
|
Sales/purchase revenue, volumes , territories, order position, customer lists, agreements, terms of sale;
Offers, bids planned /made (technical specifications and Terms & Conditions);
Cost structures (R&D, production & distribution), profit margins, capacity utilization, output;
R&D plans & their results.
Information is not commercially sensitive if:
It does not relate to parameters of competition;
It is in the public domain;
It is historic (information older than 1 year use your discretion); or
It is sufficiently aggregated to lose its sensitivity. |
| 1.4 | Benchmarking: |
Obtaining information about competition may also have anti-competitive effects; it may enable the companies to better understand where they can improve follow prices and other business practices.
| Guidance Note: Dos and Donts on Benchmarking
Always
Obtain information from public sources or from independent third parties
Normally try to obtain historical data only (i.e. data which is at least 12 months old)
Conduct a benchmarking exercise with sister companies/divisions/units
Conduct benchmarking exercise, which is unilateral, i.e., where the Company itself or with help of an independent consultant - without receiving any information from industry parties -compares its performance to that of other industry players using Competitive Intelligence;
Conduct benchmarking exercise with companies which are not competitors of Vedanta entities;
Conduct benchmarking exercise with competitors only if it relates to data which is not commercially sensitive, for e.g., human resource management, staffing, etc.
Have a legitimate detailed benchmarking work plan
Benchmarking exercises involving competitors must be approved by the compliance officer and be conducted according to a written benchmarking plan drafted specifically.
Benchmarking exercises must be limited to technical aspects of the business, unless approved by the Compliance Officer.
Never
Try to obtain information directly from competitor
Conduct internal benchmarking if it is not based on public information without checking with Legal and Compliance team of your company.
Conduct benchmarking without involving an independent organization, if possible
Make any direct contact with competitors during or in relation to an internal benchmarking exercise
Discuss the results of an internal benchmarking exercise with other participants or competitors. |
34
| 2. | Abuse of Dominance: |
A company has a dominant position if it enjoys a position of economic strength (and market power) which enables it to prevent effective competition and to behave independently of its competitors, customers, and consumers to an appreciable extent. The position starts to be assessed taking into account the companys market share. Very large market shares maintained stable for a long time can be considered as evidence for the existence of a dominant position. In practice, a company is unlikely to be individually dominant if its market share is below a certain percentage.
However, the criterion for dominance is qualitative rather than quantitative. It is not strictly concerned with a specific market share in relevant market. However, dominance is presumed by most antitrust authorities where a market share of 50% or more exists on a given relevant market. It is important to keep in mind that, being dominant is not at all problematic under antitrust law; only the abuse of a dominant position on a given relevant market is prohibited.
| 2.1 | Relevant market under antitrust law: |
A relevant market definition under antitrust law has a product/services and geographical dimension. The relevant product/service market is understood as a market comprising all those products and/or services which are regarded as interchangeable or substitutable by the consumer, by reason of the products characteristics, their prices and their intended use.
The relevant geographic market is defined as comprising the area in which the undertakings concerned are involved in the supply and demand of products or services, in which the conditions of competition are sufficiently homogeneous, and which can be distinguished from neighbouring areas because the conditions of competition are appreciably different in those areas.
The main purpose of market definition is to identify in a systematic way the competitive constraints that the companies involved face.
| 2.2 | Examples of Abuse of Dominance behaviour |
Most of the abusive practices relate to pricing policy of a dominant company.
A dominants companys pricing may neither be excessive, predatory nor discriminatory. Rebates and discounts also can constitute an issue where a dominant position is reinforced by a particular scheme. Other types of behaviour can also constitute an abuse, for instance tying or bundling (packaged selling of unconnected products) and under specific circumstances, a refusal to supply may also be abusive.
| 2.2.1 | Excessive pricing |
A dominant firm can abuse its position by charging excessive/unfair prices under antitrust law, when its pricing policy has no reasonable relation to the economic value of the product, and this can be determined by a twofold test: (i) the price-cost margin is excessive and (ii) the price imposed is either unfair in itself or when compared to competing products.
| 2.2.2 | Loyalty rebates |
A dominant firm should engage in reduction schemes which enhance loyalty. Discounts may be granted, but they should always be based on efficiency gains and linked to identifiable cost savings such as on volume. In particular, fidelity rebates, i.e., rebates conditional on the customer purchasing all or a large portion of its requirements from the supplier over a certain period are unlawful. These rebates restrict the customer from switching to alternative suppliers and as a result, are able to foreclose competing suppliers from the opportunity to make sales to those customers bound.
Target rebates, i.e., rebates that are conditional upon the distributor reaching certain targets, are in most instances unlawful for dominant firms. The same applies for discount schemes making reference to market share targets or market share minima. Non-written, non-transparent or subjective rebate schemes may be unlawful under antitrust law.
35
| 2.2.3 | Predatory Pricing |
Predatory pricing refers to a practice of a dominant firm of driving rivals out of business by selling at a price below the cost of production. It is a commercial strategy by which a dominant firm first lowers its price to a level which will ultimately force its rivals out of the market. When the latter have been successfully expelled, the company can raise the prices again and reap the rewards.
| 2.2.4 | Discrimination in prices or other trading conditions |
It is illegal for a company having a dominant position in the relevant market to enforce different prices or other trading conditions upon different customers in similar situations, or discriminatory licensing conditions, without objective justification.
Differentiation may be permissible if it is justified on objective grounds. For example, a lower price may be warranted where a distributor performs additional services not provided by other distributors or where larger volumes are purchased.
| 2.2.5 | Refusal to supply |
In general, there is no absolute obligation to supply, particularly where it concerns a potential customer with whom there has been no previous trading relationship. However, under antitrust law a dominant company is required to have some reasonable and fair commercial reason for cutting off or reducing supplies to an existing customer. Objective justifications might include real concerns about the customers creditworthiness or a shortage of the relevant product.
| Guidance Note: Dos and Donts on Abuse of Dominance
Always
Treat similar customers and distributors consistently and without any discrimination and any changes in this policy should have proper economic justification.
Ensure that refusal to supply is discussed in advance with the legal department and record the business reasons justifiable reasons such as concerns about creditworthiness or shortage of product.
Provide quantity rebates, which reflect cost savings in economies of scale, and are available to all buyers and without any restriction on buyers choice of supplier.
Never
Grant discounts rebates or fidelity bonuses only after consulting with Business Owner/Compliance officer.
Pricing should not give a false impression of excessive or predation in market.
Unreasonably and without any commercial reason cut off or reduce supplies to an existing customer/supplier.
Agree to refuse to deal based on discussions or agreements with competitors.
Do not apply different discounts / rebates for different customers unless it is economically justifiable.
Grant loyalty rebates or discounts which have the effect of tying a customer to a supplier or any rebates which are based on the percentage of its requirements purchased by a customer. |
36
| 3. | Language used in internal document and outside |
Even if a company is in full compliance with antitrust laws, its oral and written communications may still suggest otherwise. In reality, that perfectly legal behaviour can become suspect, simply because of a poor choice of words. Discussing the legality of certain behaviour in writing is inadvisable for the same reasons; while the author may be wrong in suggesting that certain behaviour may not be allowed, it nevertheless raises the attention of the antitrust authority. Be careful with the language you choose in your documents and outside commination. If your text could be misinterpreted, give more contexts and/or use clearer language. Consider how documents could be read by other employees, competitors, and antitrust law authorities.
| 3.1 | Red flag words/phrases |
The following are examples of terms and phrases which should be avoided in any communication, correspondence or agreement relating to Vedanta groups activities as they could create an unwarranted inference of anticompetitive behaviour or intent:
| Dominant/dominate the market |
A right margin | |
| Fix prices/control prices |
Control/stabilize the market | |
| Prevent imports |
Divide/partition the market | |
| Reserve a market |
Reasonable competition; no cowboys | |
| Share the market/coordinate prices |
Drive out of the market | |
| Smash/crush the competition |
Eradicate competition | |
| Eliminate from the market |
Boycott | |
| Destroy this document/delete this e-mail after reading | ||
| Our market |
||
| 4. | Regulatory Approvals by Antitrust Authorities in case of M & A |
Acquisitions of assets or equity from another company may violate the antitrust laws if the effect of the acquisition could impair competition. Parties to transactions that meet certain financial thresholds, regardless of the deals effect on competition, must give prior notice to respective antitrust authority.
To ensure the Companys compliance with this notice requirement, employees must consult to the respective Compliance Officer of the Company, before reaching an agreement on a transaction that would result in the acquisition by the Company (or by any affiliate) of either asset, equity, or a combination.
The failure to file a required notice with the antitrust agencies can have serious consequences. The parties can be:
| | Fined per day for each day that they proceed without filing. |
| | Required to undo their transaction. |
| | Forced to delay closing until they have made a filing and the specified waiting period has expired. |
The companys corporate transaction must also avoid gun jumping (that is, taking substantial steps to coordinate or integrate their activities before the required waiting period has expired). Standard contractual provisions that require a target to preserve its assets and operations until closing usually raise no issues. However, when the acquiring party exercises significant influence over the management of the target, or where the parties coordinate their business activities, the antitrust authority may conclude that the parties are enjoying the benefits of their transaction prematurely and seek to impose fines.
37
| 4.1 | Non-compete clauses |
Non-compete clauses are justified if such provisions:
| | are for limited time periods, when the transfer of the business includes the transfer of customer loyalty in the form of both goodwill and know-how and up to two years, when only goodwill is transferred; |
| | have a clearly prescribed limited geographic scope; |
| | remain limited to products forming the economic activity of the business transferred; and |
| | do not extend to a prohibition of holding shares purely for financial investment purposes - the investments can be limited, where the shareholding, directly or indirectly, leads to any management functions or any material influence in the competing company. |
| Guidance Note: Dos and Donts on M&A
Always
Submit Merger filings before the regulatory antitrust authorities (where required)
Consult Business Owner/Compliance officer before finalizing any M& A activities.
Do proper antitrust due diligence before starting M& A activities.
Operate as separate entities and continue to compete until the transaction is complete.
Do mention any reasons why pre-merger coordination between merging entities is necessary.
The Company may make unilateral decisions regarding the future of the merged entity and internally do what is necessary to carry out those decisions.
The Company and its merging entity can jointly plan for the consolidation.
Share balance sheets, income statements, and tax returns, current and projected sales revenues, lists of current products, manufacturing operations,
Share general information regarding existing joint ventures or similar relationships with third parties (giving due consideration to confidentiality obligations).
Never
Complete an M&A transaction without doing approaching the concerned antitrust authorities for their clearance.
Discuss commercially sensitive information n/related to any other entity besides the entities involved in the merger transaction.
Establish joint product development teams or co-mingle personnel until the merger is complete unless a strong justification for the same is available.
Dictate to the merging entity the prices and terms of trade to be offered by it to its customers, or what customers it may not approach.
Limit the merging entitys participation in trade shows and other business development opportunities.
Agree upon prices, sales terms, customers, and sales territories prior to closing of the merger. |

SEC CASE
FOREWORD
Scope of Investigation
This report presents estimates, as of March 31, 2022, of the extent and value of the proved oil, condensate, and sales gas reserves of certain fields in India in which Cairn Oil & Gas, Division of Vedanta Limited (Cairn) has represented it holds an interest under the terms of various production sharing contracts (PSC) and revenue sharing contracts (RSC) with the government of India (GOI). Table 1 presents a listing of the properties evaluated along with contract type, interest evaluated, and expiration of each license area.
Estimates of reserves presented in this report have been prepared in compliance with the regulations promulgated by the United States Securities and Exchange Commission (SEC). These reserves definitions are discussed in detail in the Definition of Reserves section of this report.
Reserves estimated in this report are expressed as gross reserves and net reserves. Gross reserves are defined as the total estimated petroleum remaining to be produced from these properties after March 31, 2022. Net reserves are defined as that portion of the gross reserves attributable to the interests held by Cairn after deducting all interests held by others.
| DEGOLYER AND MACNAUGHTON | 2 |
Certain properties in which Cairn has represented that it holds an interest are subject to the terms of various PSCs and RSCs. The terms of the PSC agreements generally allow for working interest participants (the Contractor) to be reimbursed for portions of capital costs and operating expenses and to share in the profits. The reimbursements and profit proceeds are converted to a barrel of oil equivalent or standard cubic foot of gas equivalent by dividing by product prices to estimate the entitlement quantities. These entitlement quantities are equivalent in principle to net reserves and are used to calculate an equivalent net share, termed an entitlement interest. In this report, Cairns net reserves or interest for certain properties subject to PSC agreements is the entitlement based on Cairns working interest. A RSC refers to an agreement between the Contractor and the government whereby the Contractor bears all exploration risks and production and development costs in return for a stipulated share of revenue. In this report, Cairns net reserves or interest for certain properties subject to RSC agreements is equivalent to Cairns working interest. A detailed explanation of these agreements is included in the Valuation of Reserves section of this report.
The fields evaluated herein are located in the CB/OS-2 PSC (3 fields), the KG-ONN-2003/1 PSC (1 field), the RJ-ON-90/1 PSC (18 fields), the PKGM-1 PSC (1 field), and the AA-ONHP-2018/01 RSC (1 field).
The CB-X, Gauri, and Lakshmi fields are located in the CB/OS-2 PSC (Cambay), the Nagayalanka field is located in the KG ONN-2003/1 PSC (Nagayalanka), the Aishwariya, Aishwariya Barmer Hill, Bhagyam, GS-V, Guda, Kaameshwari-1, Kaameshwari West-2, Mangala, N-E, N-I, Raagashwari Oil, Raagashwari Deep Gas, Saraswati, Saraswati-4 Basement, Shakti, and Tukarum fields are located in the RJ ON 90/1 PSC (Rajasthan), the Ravva field is located in the PKGM-1 PSC (Ravva), and the Hazarigaon field is located in the AA-ONHP-2018/01 RSC (Hazarigaon).
| DEGOLYER AND MACNAUGHTON | 3 |
The net entitlement interests for the properties evaluated in this report were calculated for each block and may change from year to year depending on changes to the estimated costs projected for each field, the timing of production, and price assumptions. Estimates of the entitlement interest for the total proved reserves for each block are as follows:

This report presents values for proved reserves that were estimated using prices, expenses, and costs provided by Cairn. Future prices were estimated using guidelines established by the SEC and the Financial Accounting Standards Board (FASB). Prices, expenses, and costs were provided in Indian rupees (INR) or United States dollars (U.S.$). At the request of Cairn, an exchange rate of INR75.59 per U.S.$1.00 was used. All values were estimated in INR and U.S.$, and all prices, expenses, costs, and revenue shown in this report are expressed in INR and U.S.$. A detailed explanation of the future price, expense, and cost assumptions is included in the Valuation of Reserves section of this report.
Values for proved reserves in this report are expressed in terms of future gross revenue, future net revenue, and present worth. Future gross revenue is defined as that revenue which will accrue to the evaluated interests from the production and sale of the estimated net reserves. Future net revenue is calculated by deducting cash royalties, production taxes (termed cess), operating expenses, capital costs, and Indian income tax from future gross revenue. Operating expenses include field operating expenses, workover costs, compression costs, and all other direct costs specified by Cairn. Capital costs include such items as platforms, pipelines, wells, compressors, and abandonment fund payments. Abandonment costs are represented by Cairn to be inclusive of those costs associated with the removal of equipment, plugging of wells, and reclamation and restoration associated with the abandonment. Present worth is defined as future net revenue discounted at a specified arbitrary discount rate compounded monthly over the expected period of realization. Present worth should not be construed as fair market value because no consideration was given to additional factors that influence the prices at which properties are bought and sold. In this report, present worth values using a nominal discount rate of 10 percent are reported.
Estimates of reserves and revenue should be regarded only as estimates that may change as further production history and additional information become available. Not only are such estimates based on that information which is currently available, but such estimates are also subject to the uncertainties inherent in the application of judgmental factors in interpreting such information.

| DEGOLYER AND MACNAUGHTON | 5 |
DEFINITION of RESERVES
Petroleum reserves included in this report are classified as proved. Only proved reserves have been evaluated for this report. Reserves classifications used in this report are in accordance with the reserves definitions of Rules 4l0(a) (1)(32) of Regulation SX of the SEC. Reserves are judged to be economically producible in future years from known reservoirs under existing economic and operating conditions and assuming continuation of current regulatory practices using conventional production methods and equipment. In the analyses of production-decline curves, reserves were estimated only to the limit of economic rates of production under existing economic and operating conditions using prices and costs consistent with the effective date of this report, including consideration of changes in existing prices provided only by contractual arrangements but not including escalations based upon future conditions. The petroleum reserves are classified as follows:
Proved oil and gas reserves Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically produciblefrom a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulationsprior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.
(i) The area of the reservoir considered as proved includes:
(A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.
(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.
| DEGOLYER AND MACNAUGHTON | 6 |
(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.
(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.
(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.
Probable reserves Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered.
(i) When deterministic methods are used, it is as likely as not that actual remaining quantities recovered will exceed the sum of estimated proved plus probable reserves. When probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered will equal or exceed the proved plus probable reserves estimates.
| DEGOLYER AND MACNAUGHTON | 7 |
(ii) Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where data control or interpretations of available data are less certain, even if the interpreted reservoir continuity of structure or productivity does not meet the reasonable certainty criterion. Probable reserves may be assigned to areas that are structurally higher than the proved area if these areas are in communication with the proved reservoir.
(iii) Probable reserves estimates also include potential incremental quantities associated with a greater percentage recovery of the hydrocarbons in place than assumed for proved reserves.
(iv) See also guidelines in paragraphs (iv) and (vi) of the definition of possible reserves.
Possible reserves Possible reserves are those additional reserves that are less certain to be recovered than probable reserves.
(i) When deterministic methods are used, the total quantities ultimately recovered from a project have a low probability of exceeding proved plus probable plus possible reserves. When probabilistic methods are used, there should be at least a 10% probability that the total quantities ultimately recovered will equal or exceed the proved plus probable plus possible reserves estimates.
(ii) Possible reserves may be assigned to areas of a reservoir adjacent to probable reserves where data control and interpretations of available data are progressively less certain. Frequently, this will be in areas where geoscience and engineering data are unable to define clearly the area and vertical limits of commercial production from the reservoir by a defined project.
| DEGOLYER AND MACNAUGHTON | 8 |
(iii) Possible reserves also include incremental quantities associated with a greater percentage recovery of the hydrocarbons in place than the recovery quantities assumed for probable reserves.
(iv) The proved plus probable and proved plus probable plus possible reserves estimates must be based on reasonable alternative technical and commercial interpretations within the reservoir or subject project that are clearly documented, including comparisons to results in successful similar projects.
(v) Possible reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir within the same accumulation that may be separated from proved areas by faults with displacement less than formation thickness or other geological discontinuities and that have not been penetrated by a wellbore, and the registrant believes that such adjacent portions are in communication with the known (proved) reservoir. Possible reserves may be assigned to areas that are structurally higher or lower than the proved area if these areas are in communication with the proved reservoir.
(vi) Pursuant to paragraph (iii) of the proved oil and gas reserves definition, where direct observation has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves should be assigned in the structurally higher portions of the reservoir above the HKO only if the higher contact can be established with reasonable certainty through reliable technology. Portions of the reservoir that do not meet this reasonable certainty criterion may be assigned as probable and possible oil or gas based on reservoir fluid properties and pressure gradient interpretations.
Developed oil and gas reserves Developed oil and gas reserves are reserves of any category that can be expected to be recovered:
(i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and
| DEGOLYER AND MACNAUGHTON | 9 |
(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.
Undeveloped oil and gas reserves Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.
(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.
(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.
(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in [section 210.410 (a) Definitions], or by other evidence using reliable technology establishing reasonable certainty.
The extent to which probable and possible reserves ultimately may be reclassified as proved reserves is dependent upon future drilling, testing, and well performance. The degree of risk to be applied in evaluating probable and possible reserves is influenced by economic and technological factors as well as the time element. No probable or possible reserves have been evaluated for this report.
| DEGOLYER AND MACNAUGHTON | 10 |
ESTIMATION of RESERVES
Estimates of reserves were prepared by the use of appropriate geologic, petroleum engineering, and evaluation principles and techniques that are in accordance with the reserves definitions of Rules 410(a) (1)(32) of Regulation SX of the SEC and with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (revised June 2019) Approved by the SPE Board on 25 June 2019. The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data, and production history.
Based on the current stage of field development, production performance, the development plans provided by Cairn, and analyses of areas offsetting existing wells with test or production data, reserves were classified as proved developed or proved undeveloped.
The proved undeveloped reserves estimates were based on opportunities identified in the plan of development provided by Cairn.
Cairn has represented that its senior management is committed to the development plan provided by Cairn and that Cairn has the financial capability to execute the development plan, including the drilling and completion of wells and the installation of equipment and facilities.
The volumetric method was used to estimate the original oil in place (OOIP) and original gas in place (OGIP). Structure maps were prepared to delineate each reservoir, and isopach maps were constructed to estimate reservoir volume. Electrical logs, radioactivity logs, core analyses, and other available data were used to prepare these maps as well as to estimate representative values for porosity and water saturation. When adequate data were available and when circumstances justified, material-balance methods were used to estimate OOIP or OGIP.
Estimates of ultimate recovery were obtained after applying recovery factors to OOIP and OGIP. These recovery factors were based on consideration of the type of energy inherent in the reservoirs, analyses of the petroleum, the structural positions of the properties, and the production histories. When applicable, material balance and other engineering methods were used to estimate recovery factors based on an analysis of reservoir performance, including production rate, reservoir pressure, and reservoir fluid properties.
| DEGOLYER AND MACNAUGHTON | 11 |
For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production-decline curves, reserves were estimated only to the limits of economic production as defined in the Definition of Reserves section of this report or the expiration of the fiscal agreement, as appropriate.
In certain cases, reserves were estimated by incorporating elements of analogy with similar wells or reservoirs for which more complete data were available.
Data provided by Cairn from wells drilled through March 31, 2022, and made available for this evaluation were used to prepare the reserves estimates herein. These reserves estimates were based on consideration of production data through March 31, 2022. Cumulative production, as of March 31, 2022, was deducted from the estimated gross ultimate recovery to estimate gross reserves.
Oil and condensate reserves estimated herein are to be recovered by normal field separation and are expressed in millions of barrels (106bbl). In these estimates, 1 barrel equals 42 United States gallons. For reporting purposes, oil and condensate reserves have been estimated separately and are presented herein as a summed quantity.
Gas quantities estimated herein are expressed as sales gas. Sales gas is defined as the total gas to be produced from the reservoirs, measured at the point of delivery, after reduction for fuel usage, flare, and shrinkage resulting from field separation and processing. Gas reserves estimated herein are reported as sales gas. Gas quantities are expressed at a temperature base of 60 degrees Fahrenheit (°F) and at a pressure base of 14.7 pounds per square inch absolute (psia). Gas quantities included in this report are expressed in billions of cubic feet (109ft3).
| DEGOLYER AND MACNAUGHTON | 12 |
Gas quantities are identified by the type of reservoir from which the gas will be produced. Nonassociated gas is gas at initial reservoir conditions with no oil present in the reservoir. Associated gas is both gas-cap gas and solution gas. Gas-cap gas is gas at initial reservoir conditions and is in communication with an underlying oil zone. Solution gas is gas dissolved in oil at initial reservoir conditions. Gas quantities estimated herein include both associated and nonassociated gas.
At the request of Cairn, sales gas reserves estimated herein were converted to oil equivalent using an energy equivalent factor of 6,000 cubic feet of gas per 1 barrel of oil equivalent.
Reserves estimated herein were forecast on a fiscal-year basis starting April 1 of each year and ending March 31 of the following calendar year.
Reserves were forecast to the expiration of each contract area. The expiration date for each contract area is as follows:
| Contract Area |
Expiration Date | |
| CB/OS-2 PSC |

The gross and net proved reserves evaluated herein are presented in Tables 2 and 3, respectively. A reconciliation of the net proved oil and condensate and sales gas reserves, as of March 31, 2022, is shown in Table 4.
The estimated gross and net proved developed, proved undeveloped, and total proved reserves, as of March 31, 2022, of the properties evaluated herein are summarized as follows, expressed in millions of barrels (106bbl) and billions of cubic feet (109ft3):

VALUATION of RESERVES
Revenue values in this report were estimated using initial prices, expenses, and costs provided by Cairn. Future prices were estimated using guidelines established by the SEC and the FASB. An exchange rate of INR75.59 per U.S.$1.00 was used based on representation from Cairn that it was the prevailing exchange rate on March 31, 2022. The following economic assumptions were used for estimating the revenue values reported herein:
Oil and Condensate Prices
Cairn has represented that the oil and condensate prices were based on a reference price, calculated as the unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month period prior to the end of the reporting period, unless prices are defined by contractual agreements. Cairn supplied differentials to a Brent price of U.S.$78.89 per barrel of oil and condensate and the prices were held constant thereafter. The volume-weighted average adjusted price attributable to the estimated proved reserves over the lives of the properties was U.S.$74.94 per barrel of oil and condensate.
Gas Prices
Cairn has represented that the gas prices are defined by contractual agreements based on specific market conditions. The volume-weighted average adjusted product price attributable to the estimated proved reserves was U.S.$11.16 per thousand cubic feet of gas. The average contract prices for each contract area were held constant for the lives of the properties.
| DEGOLYER AND MACNAUGHTON | 14 |
Operating Expenses, Capital Costs, and Abandonment Costs
Estimates of future operating expenses, capital costs, and abandonment costs were based on information provided by Cairn. This information included historical costs as well as operating expense and capital cost estimates for future development. Estimates of future operating expenses and capital costs, either higher or lower than the Cairn development plan estimates, may have been made to conform to the respective reserves cases. Abandonment costs, which are those costs associated with the removal of equipment, plugging of wells, and reclamation and restoration associated with the abandonment, were provided by Cairn for each field or contract area and were included as capital costs through escrow payments over the life of the remaining reserves. As of March 31, 2022, Cairn has represented that no additional funding for abandonment costs is required for the CB/OS-2 PSC. Estimates of operating expenses, capital costs, and abandonment costs provided by Cairn have been considered in determining the economic viability of the undeveloped reserves estimated herein. No escalation of operating expenses, capital costs, or abandonment costs have been applied.
Discussion of Fiscal Terms
RJ-ON-90/1 PSC (Rajasthan)
Cairn has represented that under the terms of the PSC signed with the GOI, the Contractor (Cairn and its partners) has the right to recover costs and share in the profit proceeds with the GOI. The Licensee, Oil and Natural Gas Corporation (ONGC), pays royalties of 20 percent on the wellhead value of oil and condensate sales and 10 percent on the wellhead value of gas sales. The Contractor is liable for a production tax (termed cess) of 20 percent ad valorem. Royalties and cess are considered allowable costs for cost recovery purposes. Profits are shared based on a sliding scale tied to the ratio of cumulative revenues divided by cumulative investments (exploration and development). Income taxes are assessable at statutory rates for domestic and foreign companies (Cairns interests are held by two entities: one domestic entity and one foreign entity).
CB/OS-2 PSC (Cambay)
Cairn has represented that under the terms of the PSC signed with the GOI, the Contractor has the right to recover costs and share in the profit proceeds with the GOI. The Contractor is not responsible for royalties or cess under the terms of this contract and the same are payable by Licensee (ONGC). Profits are shared based on a sliding scale tied to the after-tax rate of return. Income taxes are assessable at statutory rates for domestic companies.
| DEGOLYER AND MACNAUGHTON | 15 |
KG-ONN-2003/1 PSC (Nagayalanka)
Cairn has represented that under the terms of the PSC signed with the GOI, the Contractor has the right to recover costs with 95 percent of revenue limit and share in the profit proceeds with the GOI. The Contractor pays royalties of 12.5 percent ad valorem on the wellhead value of oil and condensate sales and 10 percent on the wellhead value of gas sales. Profits are shared based on a sliding scale tied to the ratio of cumulative revenues divided by cumulative investments (exploration and development). Income taxes are assessable at statutory rates for domestic companies.
PKGM-1 PSC (Ravva)
Cairn has represented that under the terms of the PSC signed with the GOI, the Contractor has the right to recover costs and share in the profit proceeds with the GOI. Royalties were paid at a rate of INR481 per metric ton for oil and 10 percent ad valorem of the wellhead value for gas sales until October 2019 (in accordance with the terms of the original PSC). Royalties after October 2019 (in accordance with the terms of the PSC extension) are paid at a rate of 10 percent on the wellhead value for oil and gas sales. Cess rates were INR900 per metric ton of oil until October 2019 (in accordance with the terms of the original PSC). Cess rates after October 2019 are paid at a rate of 20 percent ad valorem on the wellhead value of oil sales (in accordance with the terms of the PSC extension). Royalties and cess payments are deducted before profit sharing. Profits are shared based on a sliding scale tied to the after-tax rate of return. Income taxes are assessable at statutory rates for domestic companies.
AA-ONHP-2018/01 RSC (Hazarigaon)
Cairn has represented that under the terms of the RSC signed with the GOI, the Contractor is responsible for all production and development costs in return for a stipulated share of the revenue. This share of the state royalty is 12.5 percent for oil and 10 percent for gas. After deducting the royalty payment from the gross proceeds, the Contractor must pay an additional 40-percent royalty to the GOI. The remaining proceeds are retained by Cairn.

Standardized measure of discounted future net cash flows (SMV) and changes therein relating to proved reserves, as of March 31, 2022, are shown in Table 5. The SMV is the net present worth discounted at 10 percent. Table 6 presents a summary of net reserves and future net revenue. Tables 7 through 16 show the projection of proved developed and total proved reserves and future net revenue by contract area.
In our opinion, the information relating to estimated proved reserves, estimated future net revenue from proved reserves, and present worth of estimated future net revenue from proved reserves of oil, condensate, NGL, and gas contained in this report has been prepared in accordance with Paragraphs 932-235-50-4 through 932-235-50-7, 932-235-50-9, 932-235-50-30, and 932-235-50-31(a), (b), and (e) of the Accounting Standards Update 932-235-50, Extractive Industries Oil and Gas (Topic 932): Oil and Gas Reserve Estimation and Disclosures (January 2010) of the FASB and Rules 410(a) (1)(32) of Regulation SX and Rules 302(b), 1201, 1202(a) (1), (2), (3), (4), (8)(i), (ii), and (v)(x), and 1203(a) of Regulation SK of the SEC; provided, however, that (i) future income tax expenses have not been taken into account in estimating the future net revenue and present worth values set forth herein and (ii) estimates of the proved developed and proved undeveloped reserves are not presented at the beginning of the year. This report does not include certain disclosures required by Item 1202 (a)(8) of Regulation SK and is thus not to be used for inclusion in certain SEC filings.
To the extent the above-enumerated rules, regulations, and statements require determinations of an accounting or legal nature, we, as engineers, are necessarily unable to express an opinion as to whether the above-described information is in accordance therewith or sufficient therefor.

| Group overview | 1. Group overview Vedanta Limited (“the Company” or “the parent”) and its consolidated subsidiaries (collectively, the “Group”) is a diversified natural resource group engaged in exploring, extracting and processing minerals and oil and gas. The Group engages in the exploration, production and sale of zinc, lead, silver, copper, aluminum, iron ore and oil and gas and has a presence across India, South Africa, Namibia, Ireland, Australia, Liberia and the UAE. The Group is also in the business of commercial power generation, steel manufacturing and port operations in India and manufacturing of glass substrate in South Korea and Taiwan. The Company was incorporated on September 8,1975 under the laws of the Republic of India. The registered office of the Company is situated at 1st Floor, ‘C’ wing, Unit 103, Corporate Avenue, Atul Projects, Chakala, Andheri (East), Mumbai-400092, Maharashtra. The Company’s shares are listed on National Stock Exchange (‘NSE’) and Bombay Stock Exchange (‘BSE’) in India. In June 2007, the Company completed its initial public offering of American Depositary Shares, or ADS, each representing four equity shares, and listed its ADSs on the New York Stock Exchange (‘NYSE’). In July 2009, the Company completed its follow-on offering of an additional 131,906,011 ADS, each representing four equity shares, which are listed on the New York Stock Exchange. The American Depositary Shares (ADS) of the Company have been delisted from the NYSE effective close of trading on the NYSE on November 8, 2021. This follows the filing by the Company of Form 25 with the Securities and Exchange Commission on October 29, 2021. As a consequence of the delisting becoming effective, termination of the Deposit Agreement under which the ADS were issued (the “Deposit Agreement”) has also become effective close of trading on the NYSE on November 8, 2021. The said action has no impact on the current listing status or trading of the Company’s equity shares on BSE and NSE. The Company will continue to be subject to reporting obligations under the U.S. Securities Exchange Act of 1934 until such time as it can terminate its registration under the said Act. The Company is majority owned by Twin Star Holdings Limited (“Twin Star”), Finsider International Company Limited (“Finsider”), Vedanta Holdings Mauritius II Limited (“VHM2L”), Vedanta Holdings Mauritius Limited (“VHML”), Welter Trading Limited (“Welter”) and Vedanta Netherlands Investments BV (“VNIBV”), which are in turn wholly-owned subsidiaries of Vedanta Resources Limited (“VRL”), a company incorporated in the United Kingdom. VRL, through its subsidiaries, held 55.1% and 69.68% of the Company’s equity as at March 31, 2021 and March 31, 2022, respectively. VRL, through its wholly owned subsidiaries, acquired 541,731,161 equity shares of the Company during the current year, thereby increasing their shareholding in the Company from 55.1% to 69.68%Details of the Group’s various businesses are as follows:
Subsequent to the Balance Sheet date, WCL has signed a Memorandum of Understanding with Government of Liberia to start its Iron ore mining operations in Liberia, which could not be started earlier due to the outbreak of Ebola epidemic in 2014. Activities to begin the operations are commenced in June 2022.
The Group’s copper business in Tamil Nadu, India has received an order from the Tamil Nadu Pollution Control Board (“TNPCB”) on April 9, 2018, rejecting the Company’s application for renewal of consent to operate under the Air and Water Acts for the 400,000TPA copper smelter plant in Tuticorin for want of further clarification and consequently the operations were suspended. The Company has filed an appeal with TNPCB Appellate authority against the said order. During the pendency of the appeal, TNPCB through its order dated May 23, 2018 ordered for disconnection of electricity supply and closure of copper smelter plant. Post such order, the state government on May 28, 2018 ordered the permanent closure of the plant. We continue to engage with the Government of India and relevant authorities to enable the restart of operations at Copper India. (Refer Note 3(c)(I)(iii)). Further, the Company’s copper business includes refinery and rod plant at Silvassa consisting of a 133,000 MT of blister/ secondary material processing plant, a 216,000 TPA copper refinery plant and a copper rod mill with an installed capacity of 258,000 TPA. The plant continues to operate , catering primarily to the domestic market.In addition, the Group owns and operates the Mt. Lyell copper mine in Tasmania, Australia through its subsidiary CMT and a precious metal refinery and copper rod plant in Fujairah, UAE through its subsidiary Fujairah Gold FZC. The operations of Mt Lyell copper mine were suspended in January 2014 following a mud slide incident and were put into care and maintenance since July 9, 2014 following a rock fall incident in June 2014. In November 2020, the Group executed an arrangement with a third party for further exploration with an option to fully divest its shareholding in return for royalties on successful mining and production.

| Significant accounting policies | 3(a) Significant accounting policies A. Basis of consolidation Subsidiaries: The consolidated financial statements incorporate the results of the Company and all its subsidiaries (the “Group”), being the entities that it controls. Control is evidenced where the Group has power over the investee, is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Power is demonstrated through existing rights that give the ability to direct relevant activities, which significantly affect the entity’s returns. The financial statements of subsidiaries are prepared for the same reporting year as the parent company. Where necessary, adjustments are made to the financial statements of subsidiaries to align the accounting policies in line with accounting policies of the Group. For non-wholly owned subsidiaries, a share of the profit/(loss) for the financial year and net assets is attributed to the non-controlling interests as shown in the consolidated financial statements. Liability for put option issued to non-controlling interests which do not grant present access to ownership interest to the Group is recognised at present value of the redemption amount and is reclassified from equity. At the end of each reporting period, the non-controlling interests subject to put option is derecognised and the difference between the amount derecognised and present value of the redemption amount, which is recorded as a financial liability, is accounted for as an equity transaction. For acquisitions of additional interests in subsidiaries, where there is no change in control, the Group recognises a reduction to the non-controlling interest of the respective subsidiary with the difference between this figure and the cash paid, inclusive of transaction fees, being recognised in equity. Similarly, upon dilution of controlling interests the difference between the cash received from sale or listing of the subsidiary shares and the increase to non-controlling interest is also recognised in equity. The results of subsidiaries acquired or disposed off during the year are included in the consolidated statements of profit or loss from the effective date of acquisition or up to the effective date of disposal, as appropriate. Intra-Group balances and transactions, and any unrealised profits arising from intra-Group transactions are eliminated. Unrealised losses are eliminated unless costs cannot be recovered. Joint arrangements A Joint arrangement is an arrangement of which two or more parties have joint control. Joint control is considered when there is contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Investments in joint arrangements are classified as either joint operations or joint venture. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement, have rights to the assets, and obligations for the liabilities relating to the arrangement. 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. The Group has both joint operations and joint ventures. Joint operations The Group has joint operations within its oil and gas segment. It participates in several unincorporated joint operations which involve the joint control of assets used in oil and gas exploration and producing activities. The Group accounts for its share of assets, liabilities, income and expenditure of joint operations in which the Group holds an interest. Liabilities in unincorporated joint operations where the Group is the operator are accounted for at gross values (including share of other partners) with a corresponding receivable from the venture partner. These have been included in the consolidated financial statements under the appropriate headings. Details of joint operations are set out in Note 34(b). Joint venture The Group accounts for its interest in joint venture using the equity method (see Note B below), after initially being recognised at cost in the consolidated statements of financial position. Goodwill arising on the acquisition of joint venture is included in the carrying value of investments in joint venture. B. Investments in associates: An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but, is not control or joint control over those policies. Investments in associates are accounted for using the equity method. Goodwill arising on the acquisition of associates is included in the carrying value of investments in associate. Equity method of accounting Under the equity method of accounting applicable for investments in associates and joint ventures, investments are initially recorded at the cost to the Group and then, in subsequent periods, the carrying value is adjusted to reflect the Group’s share of the post-acquisition profits or losses of the investee, the Group’s share of other comprehensive income of the investee, other changes to the investees net assets and is further adjusted for impairment losses, if any. Dividend received or receivable from associate and joint ventures are recognised as a reduction in carrying amount of the investment. The consolidated statements of profit or loss and consolidated statements of comprehensive income include the Group’s share of investee’s results, except where the investee is generating losses share of such losses in excess of the Group’s interest in that investee are not recognised. Losses recognised under the equity method in excess of the Group’s investment in ordinary shares are applied to the other components of the Group’s interest that forms part of Group’s net investment in the investee in the reverse order of their seniority (i.e., priority in liquidation). If the Group’s share of losses in an associate or joint venture equals or exceeds its interests in the associate or joint venture, the Group discontinues the recognition of further losses. Additional losses are provided for only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associate/ joint venture. Unrealised gains arising from transactions with associates and joint venture are eliminated against the investment to the extent of the Group’s interest in these entities. Unrealised losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment of the asset transferred. Accounting policies of equity accounted investees are changed where necessary to ensure consistency with the policies adopted by the Group. The carrying amount of equity accounted investments are tested for impairment in accordance with the policy described in Note 3 (a)(I) below. C. Business combinations Business combinations except those under common control are accounted for under the acquisition method. The acquiree’s identifiable assets, liabilities and contingent liabilities that meet the conditions for recognition under IFRS 3 (Business Combinations) Excess of fair value of purchase consideration and the acquisition date non-controlling interest over the acquisition date fair value of identifiable assets acquired and liabilities assumed is recognised as goodwill. Goodwill arising on acquisitions is reviewed for impairment annually. Where the fair values of the identifiable assets and liabilities exceed the purchase consideration, the Group re-assesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognised at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the surplus is credited to the consolidated statements of profit or loss in the period of acquisition. Where it is not possible to complete the determination of fair values by the date on which the first post-acquisition financial statements are approved, a provisional assessment of fair value is made and any adjustments required to those provisional fair values are finalised within 12 months of the acquisition date. Those provisional amounts are adjusted through goodwill during the measurement period, or additional assets or liabilities are recognised, or the amounts at which existing assets or liabilities were recorded are remeasured to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognised at that date. These adjustments are called as measurement period adjustments. The measurement period does not exceed twelve months from the acquisition date. Any non-controlling interest in an acquiree is measured at fair value or as the non-controlling interest’s proportionate share of the acquiree’s net identifiable assets. This accounting choice is made on a transaction by transaction basis. Acquisition expenses are charged to the consolidated statements of profit or loss. If the Group acquires a group of assets in a company that does not constitute a business combination in accordance with IFRS 3, the cost of the acquired group of assets is allocated to the individual identifiable assets acquired based on their relative fair value. Common control transactions A business combination involving entities or businesses under common control is a business combination in which all of the combining entities or businesses are ultimately controlled by the same party or parties both before and after the business combination and the control is not transitory. The transactions between entities under common control are scoped out of IFRS 3 and there is no authoritative literature for these transactions under IFRS. As a result, the Group adopted accounting principles similar to the pooling-of-interest D. Revenue recognition Sale of products/ rendering of services (including revenue from contracts with customers) The Group’s revenue from contracts with customers is mainly from the sale of copper, aluminium, iron ore, zinc, oil and gas, power, steel, glass substrate and port operations. 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 Group 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 Group’s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME) and crude index, 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 IFRS 9 ( Financial Instruments) (Revenue from Contracts with Customers) Revenue from oil, gas and condensate sales represent the Group’s share in the revenue from sale of such products, by the joint operations, and is recognised as and when control in these products gets transferred to the customers. In computing its share of revenue, the Group excludes government’s share of profit which gets accounted for when the obligation in respect of the same arises. Revenue from sale of power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at a rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable. Where the Group acts as a port operator, revenues relating to operating and maintenance phase of the port contract are measured at the amount that Group expects to be entitled to for the services provided. A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Group performs part of its obligation 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 the Group’s future performance. A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration from the customer. If a customer pays consideration before the Group transfers goods or services to the customer, a contract liability is recognised when the payment is received. The advance payments received, plus a specified rate of return/ discount at the prevailing market rates, are settled by supplying respective goods over a period of up to twenty four months under an agreed delivery schedule as per the terms of the respective agreements. As these are contracts that the Group expects and has the ability to fulfil through delivery of a non-financial item, these are presented as advance from customers and are recognised as revenue as and when control of respective commodities is transferred to customers under the agreements. The fixed rate of return/discount is treated as finance cost. The portion of the advance where either the Group does not have a unilateral right to defer settlement beyond 12 months or expects settlement within 12 months from the balance sheet date is classified as current liability. Interest income Interest income from debt instruments is recognised using the effective interest rate method. The effective interest rate is the rate that discounts estimated future cash receipts through the expected life of the financial asset to the gross carrying amount of a financial asset. When calculating the effective interest rate, the Group estimates the expected cash flows by considering all the contractual terms of the financial instrument (for example, prepayment, extension, call and similar options) but does not consider the expected credit losses. Dividends Dividend income is recognised in the consolidated statements of profit or 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 Group, and the amount of the dividend can be measured reliably. E (a) Property, plant and equipment (i) Mining properties When a decision is taken that a mining properties is viable for commercial production (i.e., when the Group determines that the mining properties will provide sufficient and sustainable return relative to the risks and the Group decided to proceed with the mine development), all further pre-production primary development expenditure other than that on land, buildings, plant, equipment and capital work in progress is capitalized as property, plant and equipment under the heading “Mining properties” together with any amount transferred from “Exploration and evaluation” assets. The costs of mining properties include the costs of acquiring and developing mining properties. The stripping cost incurred during the production phase of a surface mine is deferred to the extent the current period stripping cost exceeds the average period stripping cost over the life of mine and recognised as an asset if such cost provides a benefit in terms of improved access to ore in future periods and certain criteria are met. When the benefit from the stripping costs is realized in the current period, the stripping costs are accounted for as the cost of inventory. If the costs of inventory produced and the stripping activity asset are not separately identifiable, a relevant production measure is used to allocate the production stripping costs between the inventory produced and the stripping activity asset. The Group uses the expected volume of waste compared with the actual volume of waste extracted for a given value of ore/mineral production for the purpose of determining the cost of the stripping activity asset. Deferred stripping costs are included in 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. In circumstances where a mining property is abandoned, the cumulative capitalised costs relating to the property are written off in the period in which it occurs, i.e., when the Group determines that the mining property will not provide sufficient and sustainable returns relative to the risks and the Group decides not to proceed with the mine development. Commercial reserves are proved and probable reserves as defined by the ‘JORC’ Code, ‘MORC’ code or ‘SAMREC’ Code. Changes in the commercial reserves affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. (ii) Oil and gas assets- (developing/producing assets) For oil and gas assets a successful efforts based accounting policy is followed. Costs incurred prior to obtaining the legal rights to explore an area are expensed immediately to the consolidated statements of profit or loss. All costs incurred after the technical feasibility and commercial viability of producing hydrocarbons has been demonstrated are capitalised within property, plant and equipment—development/producing assets on a field-by-field Net proceeds from any disposal of development/producing assets are credited against the previously capitalised cost. A gain or loss on disposal of a development/producing asset is recognised in the consolidated statements of profit or loss to the extent that the net proceeds exceed or are less than the appropriate portion of the net capitalised costs of the asset. (iii) Other property, plant and equipment 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. If significant parts of an item of property, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment. All other expenses on existing property, plant and equipment, including day-to-day Gains and losses on disposal of an item of property, plant and equipment, computed as the difference between the net disposal proceeds and the carrying amount of the asset, are included in the consolidated statements of profit or loss when the asset is derecognised. Major inspection and overhaul expenditure is capitalised, if the recognition criteria are met. (iv) Assets under construction Assets under construction are capitalised in the assets under construction 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 and any obligatory decommissioning costs are capitalised until the period of commissioning has been completed and the asset is ready for its intended use. Asset under construction are presented at cost, net of accumulated impairment losses, if any. (v) Depreciation, depletion and amortisation expense Mining properties and other assets in the course of development or construction, freehold land and goodwill are not depreciated or amortised. Mining properties The capitalised mining properties are amortised on a unit-of-production Oil and gas producing facilities All expenditures carried within each field are amortised from the commencement of production on a unit of production basis, which is the ratio of oil and gas production in the period to the estimated quantities of commercial reserves at the end of the period plus the production in the period, generally on a field-by-field Commercial reserves are proven and probable oil and gas reserves, which are defined as the estimated quantities of crude oil, natural gas and natural gas liquids which geological, geophysical and engineering data demonstrate with a specified degree of certainty to be recoverable in future years from known reservoirs and which are considered commercially producible. Costs used in the unit of production calculation comprise the net book value of capitalised costs plus the estimated future field development costs required to access the commercial reserves. Changes in the estimates of commercial reserves or future field development costs are recorded prospectively. The estimates of hydrocarbon reserves and resources have been derived in accordance with the Society of Petroleum Engineers “Petroleum Resources Management System (2018)”. Other assets Depreciation on property, plant and equipment is calculated using the straight-line method (SLM) to allocate their cost, net of their residual values, over their estimated useful lives (determined by the management) as given below. Management’s assessment takes into account, inter alia, the nature of the assets, the estimated usage of the assets, the operating conditions of the assets, past history of replacement and maintenance support. Estimated useful life of assets are as follows:
Major inspection and overhaul costs are depreciated over the estimated life of the economic benefit to be derived from such costs. The carrying amount of the remaining previous overhaul cost is charged to the consolidated statements of profit or loss if the next overhaul is undertaken earlier than the previously estimated life of the economic benefit. The Group reviews the residual value and useful life of an asset at least at each financial year end , and if expectations differ from previous estimates the change is accounted for as a change in accounting estimate. (b) Exploration and 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 which includes depreciation and applicable operating costs of related support equipment and facilities and other costs of exploration activities:
Exploration expenditure incurred in the process of determining oil and gas exploration targets is capitalised within “exploration and evaluation assets “and subsequently allocated to drilling activities. Exploration drilling costs are initially capitalised on a well-by-well well-by-well Following appraisal of successful exploration wells, if commercial reserves are established and technical feasibility for extraction demonstrated, then the related capitalised exploration costs are transferred into a single field cost centre within property, plant and equipment—development/ producing assets (oil and gas properties) after testing for impairment. Where results of exploration drilling indicate the presence of hydrocarbons which are ultimately not considered commercially viable, all related costs are written off to the consolidated statements of profit or loss. Expenditure incurred on the acquisition of a licence interest is initially capitalised on a licence-by-licence Net proceeds from any disposal of an exploration asset are initially credited against the previously capitalised costs. Any surplus/ deficit is recognised in the consolidated statements of profit or loss. (c) Other Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. Subsequently, intangibles assets are measured at cost less accumulated amortisation and accumulated impairment losses, if any. The Group recognises port concession rights as “Intangible Assets” arising from a service concession arrangement in which the grantor controls or regulates the services provided and the prices charged and also controls any significant residual interest in the infrastructure such as property, plant and equipment, irrespective whether the infrastructure is existing infrastructure of the grantor or the infrastructure is constructed or purchased by the Group as part of the service concession arrangement. Such an intangible asset is recognised by the Group initially at cost determined as the fair value of the consideration received or receivable for the construction service delivered and is capitalised when the project is complete in all respects. Port concession rights are amortised on straight line basis over the balance of license period. The concession period is 30 years from the date of the award. Any addition to the port concession rights are measured at fair value on recognition. Port concession rights also include certain property, plant and equipment in accordance with IFRIC 12 (Service Concession Arrangements) Intangible assets are amortised over their estimated useful life on a straight line basis. Software is amortised over the estimated useful life ranging from 2-5 years. Amounts paid for securing mining rights are amortised over the period of the mining lease ranging from 16-25 years. Technological know-how and acquired brand are amortised over the estimated useful life of ten years. 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 recognised in the consolidated statements of profit or loss when the asset is derecognised. The amortisation period and the amortisation method are reviewed at least at each financial year end. If the expected useful life of the asset is different from previous estimates, the change is accounted for prospectively as a change in accounting estimate. F. Non-current assets held for sale Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered through a sale transaction rather than through continuing use. This condition is regarded as met only when the sale is highly probable and the asset (or disposal group) is available for immediate sale in its present condition. Management must be committed to the sale which should be expected to qualify for recognition as a completed sale within one year from the date of classification. Non-current assets and disposal groups classified as held for sale are not depreciated and are measured at the lower of carrying amount and fair value less costs to sell. Such assets and disposal groups are presented separately on the face of the consolidated statements of financial position. G. 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. (a) Financial Assets – Recognition and subsequent measurement All financial assets are recognised initially at fair value plus, in the case of financial assets not recorded at fair value through profit or loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognised on the trade date, i.e., the date that the Group commits to purchase or sell the asset. For purposes of subsequent measurement, financial assets are classified in four categories: Debt instruments at amortised cost A ‘debt instrument’ is measured at amortised cost if both the following conditions are met:
After initial measurement, such financial assets are subsequently measured at amortised cost using the Effective Interest Rate (EIR) method. Amortised 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 amortisation is included in interest income in consolidated statements of profit or loss. The losses arising from impairment are recognised in consolidated statements of profit or loss. Debt instruments at fair value through other comprehensive income (FVOCI) A ‘debt instrument’ is classified as at FVOCI if both of the following criteria are met:
Debt instruments included within the FVOCI category are measured initially, as well as at each reporting date, at fair value. Fair value movements are recognised in other comprehensive income (OCI). However, interest income, impairment losses and reversals and foreign exchange gain or loss are recognized in the consolidated statements of profit or loss. On derecognition of the asset, cumulative gain or loss previously recognised in other comprehensive income is reclassified from the equity to consolidated statements of profit or loss. Interest earned whilst holding fair value through other comprehensive income debt instrument is reported as interest income using the EIR method. Debt instruments at fair value through 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 amortised cost or as FVOCI is classified as FVTPL. In addition, the Group may elect to designate a debt instrument which otherwise meets amortised cost or FVOCI criteria as FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (referred to as ‘accounting mismatch’). Debt instruments included within the FVTPL category are measured at fair value with all changes being recognised in consolidated statement of profit or loss. The Group has not designated any debt instrument as FVTPL. Equity Instruments All equity investments in the scope of IFRS 9 are measured at fair value. Equity instruments which are held for trading and contingent consideration recognised by an acquirer in a business combination to which IFRS 3 applies are classified as at FVTPL. For all other equity instruments, the Group may make an irrevocable election to present in other comprehensive income any subsequent changes in the fair value. The Group makes such election on an instrument-by-instrument If the Group decides to classify an equity instrument as at FVOCI, then all fair value changes on the instrument, excluding dividends, are recognised in the OCI. There is no recycling of the amounts from OCI to profit or loss, even on sale of investment. However, the Group may transfer the cumulative gain or loss within equity. For equity instruments which are classified as FVTPL, all subsequent fair value changes are recognised in the consolidated statements of profit or loss. (b) Financial Assets—Derecognition The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. (c) Impairment of Financial Assets In accordance with IFRS 9, the Group applies expected credit loss (“ECL”) model for measurement and recognition of impairment loss on the following financial assets:
The Group follows the ‘simplified approach’ for recognition of impairment loss allowance on trade receivables, contract assets and lease receivables. The application of simplified approach does not require the Group 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. At each reporting date, for recognition of impairment loss on other financial assets and risk exposure, the Group 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 Group reverts to recognising impairment loss allowance based on 12-month ECL. Lifetime ECL is the expected credit loss 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 Group in accordance with the contract and all the cash flows that the entity expects to receive, discounted at the original EIR. ECL impairment (loss allowance)/reversal during the year is recognised as (expense)/income in the consolidated statements of profit or loss. The consolidated statements of financial position presentation for various financial instruments is described below:
For assessing increase in credit risk and impairment loss, the Group 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. The Group does not have any purchased or originated credit-impaired (POCI) financial assets, i.e., financial assets which are credit impaired on purchase/origination. (d) Financial Liabilities – Recognition and Subsequent measurement Financial liabilities are classified, at initial recognition, at fair value through profit or loss, or as loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial liabilities are recognised initially at fair value, and in the case of financial liabilities at amortised cost, net of directly attributable transaction costs. The Group’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts, financial guarantee contracts 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 Group that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. 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 recognised in the consolidated statements 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 IFRS 9 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognised in OCI. These gains/ losses are not subsequently transferred to consolidated statements of profit or loss. However, the Group may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognised in the consolidated statements of profit or loss. The Group has not designated any financial liability at fair value through profit or loss. Financial liabilities at amortised cost (Loans, Borrowings and Trade and Other payables) After initial recognition, interest-bearing loans and borrowings and trade and other payables are subsequently measured at amortised cost using the EIR method. Gains and losses are recognised in consolidated statements of profit or loss when the liabilities are derecognised as well as through the EIR amortisation process. Amortised 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 amortisation is included as finance and other costs in the consolidated statements of profit or loss. (e) Financial Liabilities – Derecognition A financial liability is derecognised 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 recognised in the consolidated statements of profit or loss. (f) 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 IFRS 9, the Group does not separate embedded derivatives. Rather, it applies the classification requirements contained in IFRS 9 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 recognised in the consolidated statements of profit or loss, unless designated as effective hedging instruments. (g) Equity Instruments An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments issued by the Group are recognised at the proceeds received, net of direct issue costs. (h) Offsetting of Financial Instruments Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability 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 Group enters into forward, option, swap contracts and other derivative financial instruments. The Group does not hold derivative financial instruments for speculative purposes. Such derivative financial instruments are initially recognised 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 the consolidated statements of profit or loss, except for the effective portion of cash flow hedges, which is recognised in OCI and later reclassified to the consolidated statements of 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:
At the inception of a hedge relationship, the Group formally designates and documents the hedge relationship to which the Group wishes to apply hedge accounting. The documentation includes the Group’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 Group 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 ongoing 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: (1) Fair value hedges Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognised in the consolidated statements of 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. When an unrecognised 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 recognised as an asset or liability with a corresponding gain or loss recognised in the consolidated statements of profit or loss. Hedge accounting is discontinued when the Group revokes the hedge relationship, the hedging instrument or hedged item expires or is sold, terminated, or exercised or no longer meets the criteria for hedge accounting and the unamortised fair value is recognised immediately in statement of profit or loss. (2) Cash flow hedges The effective portion of the gain or loss on the hedging instrument is recognised in OCI in the cash flow hedge reserve, while any ineffective portion is recognised immediately in the consolidated statements of profit or loss. Amounts recognised in OCI are transferred to the consolidated statements of profit or loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognised or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognised in 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 recognised in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met. (3) Hedges of a net investment Hedges of a net investment in a foreign operation, including a hedge of a monetary item that is accounted for as part of the net investment, are accounted for in a way similar to cash flow hedges. Gains or losses on the hedging instrument relating to the effective portion of the hedge are recognised in OCI while any gains or losses relating to the ineffective portion are recognised in the consolidated statements of profit or loss. On disposal of the foreign operation, the cumulative value of any such gains or losses recorded in equity is reclassified to the consolidated statements of profit or loss. H. Borrowing costs Borrowing cost includes interest expense as per EIR and exchange differences arising from foreign currency borrowings to the extent they are regarded as an adjustment to the interest cost. Borrowing costs directly relating to the acquisition, construction or production of a qualifying capital project under construction are capitalised and added to the project cost during construction until such time that the assets are substantially ready for their intended use, i.e., when they are capable of commercial production. Borrowing costs relating to the construction phase of a service concession arrangement is capitalised as part of the cost of the intangible asset. Where funds are borrowed specifically to finance a qualifying capital project, the amount capitalised represents the actual borrowing costs incurred. Where surplus funds are available out of money borrowed specifically to finance a qualifying capital project, the income generated from such short-term investments is deducted from the total capitalised borrowing cost. If any specific borrowing remains outstanding after the related asset is ready for its intended use or sale, that borrowing then becomes part of general borrowing. Where the funds used to finance a project form part of general borrowings, the amount capitalised is calculated using a weighted average of rates applicable to relevant general borrowings of the Group during the year. All other borrowing costs are recognised in the consolidated statements of profit or loss in the year in which they are incurred. Capitalisation of interest on borrowings related to construction or development projects is ceased when substantially all the activities that are necessary to make the assets ready for their intended use are complete or when delays occur outside of the normal course of business. EIR is the rate that discounts the estimated future cash payments or receipts over the expected life of the financial liability or a shorter period, where appropriate, to the amortised cost of a financial liability. When calculating the effective interest rate, the Group estimates the expected cash flows by considering all the contractual terms of the financial instrument (for example, prepayment, extension, call and similar options). I. Impairment 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. The Group assesses at each reporting date, whether there is an indication that an asset may be impaired. The Group 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 recognised impairment losses. Internal and external factors, such as worse economic performance than expected, changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognised impairment losses. If any such indication exists or in case of goodwill where annual testing of impairment is required, then an impairment review is undertaken and 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 Group and not applicable to entities in general. Fair value for mineral and oil and gas 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 Group’s continued use and do not 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. The carrying value is net of deferred tax liability recognised in the fair value of assets acquired in the business combination. 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 and impairment loss is recognised in the consolidated statements of profit or loss. Any reversal of the previously recognised 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 recognised except if initially attributed to goodwill. Exploration and evaluation assets: In assessing whether there is any indication that an exploration and evaluation asset may be impaired, the Group considers, as a minimum, the following indicators:
When a potential impairment is identified, an assessment is performed for each area of interest in conjunction with the group of operating assets (representing a cash-generating unit) to which the exploration and evaluation assets is attributed. Exploration areas in which reserves have been discovered but require major capital expenditure before production can begin, are continually evaluated to ensure that commercial quantities of reserves exist or to ensure that additional exploration work is under way or planned. To the extent that capitalised expenditure is no longer expected to be recovered, it is charged to the consolidated statements of profit or loss. J. Leases The Group assesses at contract inception, all arrangements to determine whether they are, or contain, a lease i.e., if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. (a) Group as a lessor Leases in which the Group 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 recognised 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 recognised over the lease term on the same basis as rental income. Contingent rents are recognised as revenue in the period in which they are earned. Leases are classified as finance leases when substantially all of the risks and rewards of ownership transfer from the Group to the lessee. Amounts due from lessees under finance leases are recorded as receivables at the Group’s net investment in the leases. Finance lease income is allocated to accounting periods so as to reflect a constant periodic rate of return on the net investment outstanding in respect of the lease. (b) Group as a lessee The Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognises lease liabilities towards future lease payments and right-of-use (i) Right-of-use The Group recognises right-of-use Right-of-use right-of-use right-of-use Right-of-use (ii) Lease liabilities At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (in some instances, in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognised as expenses (unless they are incurred to produce inventories) in the period in which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is generally not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. The Group’s lease liabilities are included in trade and other payables. (iii) Short-term leases and leases of low-value assets The Group applies the short-term lease recognition exemption to its short-term leases of equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low-value assets are recognised as expense on a straight-line basis over the lease term. K. Government grants Grants and subsidies from the government are recognised when there is reasonable assurance that (i) the Group 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 recognised as income on a systematic basis in the consolidated statements of profit or loss over the periods necessary to match them with the related costs which they are intended to compensate. Government grants relating to tangible fixed assets are deducted in calculating the carrying amount of the assets and recognised in the consolidated statements of profit or loss over the expected useful lives of the respective assets as reduced depreciation expense. 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 recognised 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. L. Inventories Inventories and work-in-progress Cost is determined on the following basis:
Net realisable value is determined based on estimated selling price, less further costs expected to be incurred for completion and disposal. M. Taxation Tax expense represents the sum of current tax and deferred tax. Current tax is provided at amounts expected to be paid (or recovered) using the tax rates and laws that have been enacted or substantively enacted by the reporting date and includes any adjustment to tax payable in respect of previous years. Subject to the exceptions below, 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 and on carry forward of unused tax credits and unused tax losses:
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realised 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 recognised outside the consolidated statements of profit or loss is recognised either in other comprehensive income or equity. The carrying amount of deferred tax assets (including MAT credit entitlement) is reviewed at each reporting date and is adjusted to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the asset to be recovered. Unrecognised deferred tax assets are re-assessed at each reporting date and are recognised 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 deferred tax liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. Deferred tax is provided on temporary differences arising on acquisitions that are categorised as Business Combinations. Deferred tax is recognised at acquisition as part of the assessment of the fair value of assets and liabilities acquired. Subsequently deferred tax is charged or credited in the consolidated statements of profit or loss/other comprehensive income as the underlying temporary difference is reversed. Further, management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group reflects the effect of uncertainty for each uncertain tax treatment by using either most likely method or expected value method, depending on which method predicts better resolution of the treatment. N. Retirement benefit schemes The Group operates or participates in a number of defined benefit and defined contribution schemes, the assets of which (where funded) are held in separately administered funds. For defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation each year, separately for each plan, using the projected unit credit method by third party qualified actuaries. Remeasurements , including effects of asset ceiling and return on plan assets (excluding amounts included in interest on the net defined benefit liability) and actuarial gains and losses arising in the year, are recognised in full in other comprehensive income and are not recycled to the consolidated statements of profit or loss. Past service costs are recognised in the consolidated statements of profit or loss on the earlier of:
Net interest is calculated by applying a discount rate to the net defined benefit liability or asset at the beginning of the period. Defined benefit costs are split into current service cost, past service cost, net interest expense or income and remeasurement, and gains and losses on curtailments and settlements. Current service cost and past service costs are recognised within cost of sales and administrative expenses and distribution expenses. Net interest expense or income is recognised within finance and other costs. For defined contribution schemes, the amount charged to the consolidated statements of profit or loss in respect of pension costs and other post-retirement benefits is the contributions payable in the year, recognised as and when the employee renders related services. O. Share-based payments Certain employees (including executive directors) of the Group receive part of their remuneration in the form of share-based payment transactions, whereby employees render services in exchange for shares or rights over shares (‘equity-settled transactions’). The cost of equity-settled transactions with employees is measured at fair value of share awards at the date at which they are granted. The fair value of share awards is determined with the assistance of an external valuer and the fair value at the grant date is expensed on a proportionate basis over the vesting period based on the Group’s estimate of shares that will eventually vest. The estimate of the number of awards likely to vest is reviewed at each reporting date up to the vesting date at which point the estimate is adjusted to reflect the current expectations. The resultant increase in equity is recorded in share-based payment reserve. In case of cash-settled transactions, a liability is recognised for the fair value of cash-settled transactions. The fair value is measured initially and at each reporting date up to and including the settlement date, with changes in fair value recognised in employee benefits expense. The fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The fair value is determined with the assistance of an external valuer. P. Provisions, contingent liabilities and contingent assets The assessments undertaken in recognising provisions and contingencies have been made in accordance with the applicable IFRS. Provisions represent liabilities for which the amount or timing is uncertain. Provisions are recognised when the Group 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 recognised in the consolidated statements of profit or loss as finance and other costs. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate. A contingent liability is a possible obligation that arises from past events whose existence will be confirmed by the occurrence or non-occurrence of one or more uncertain future events beyond the control of the Group or a present obligation that is not recognised because it is not probable that an outflow of resources will be required to settle the obligation. A contingent liability also arises in extremely rare cases where there is a liability that cannot be recognised because it cannot be measured reliably. In certain situations, the Group does not recognise a contingent liability but discloses its existence in the consolidated financial statements. Contingent assets are not recognised but disclosed in the financial statements when an inflow of economic benefit is probable. The Group has significant capital commitments in relation to various capital projects which are not recognised in the consolidated statements of financial position. Q. 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 or oil fields. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalised at the start of each project as soon as the obligation to incur such costs arises. These costs are charged to the consolidated statements of profit or loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision. The cost estimates are reviewed periodically and are adjusted to reflect known developments which may have an impact on the cost estimates or life of operations. 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. The unwinding of the discount is shown as finance and other costs in the consolidated statements of profit or loss. Costs for the restoration of subsequent site damage which is caused on an ongoing basis during production are provided for at their net present value and charged to the consolidated statements of profit or loss as extraction progresses. Where the costs of site restoration are not anticipated to be material, they are expensed as incurred. R. Accounting for foreign currency transactions and translations The functional currency for each entity in the Group is determined as the currency of the primary economic environment in which it operates. For all principal operating subsidiaries, the functional currency is normally the local currency of the country in which it operates with the exception of oil and gas business operations which have US dollar functional currency as that is the currency of the primary economic environment in which it operates. In the financial statements of individual group companies, transactions in currencies other than the respective functional currencies are translated into their functional currencies at the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in other currencies are translated into functional currencies 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 consolidated statements of profit or loss except those where the monetary item is designated as an effective hedging instrument of the currency risk of designated forecasted sales or purchases, which are recognised in the other comprehensive income. Exchange differences which are regarded as an adjustment to interest costs on foreign currency borrowings are capitalised as part of borrowing costs in qualifying assets. For the purposes of the consolidation of financial statements, items in the consolidated statements of profit or loss of those businesses for which the Indian Rupees is not the functional currency are translated into Indian Rupees at the average rates of exchange during the year/ exchange rates as on the date of transaction. The related consolidated statements of financial position is translated into Indian rupees at the rates as at the reporting date. Exchange differences arising on translation are recognised in the consolidated statements of other comprehensive income. On disposal of such entities the deferred cumulative exchange differences recognised in equity relating to that particular foreign operation are recognised in the consolidated statements of profit or loss. S. Earnings per share The Group 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 potentially dilutive equity shares. T. Treasury shares The Group has created an Employee Benefit Trust (EBT) for providing share-based payment to its employees. The Group uses EBT as a vehicle for distributing shares to employees under the employee remuneration schemes. The EBT buys shares of the Company from the market for giving shares to employees. The shares held by EBT are treated as treasury shares. Own equity instruments that are reacquired (treasury shares) are recognised at cost and deducted from equity. No gain or loss is recognised in profit or loss on the purchase, sale, issue or cancellation of the Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognised in equity. Share options, whenever exercised, are satisfied with treasury shares. U. Current and non-current classification The Group presents assets and liabilities in the consolidated statements of financial position based on current / non-current classification. An asset is classified as current when it satisfies any of the following criteria:
All other assets are classified as non-current. A liability is classified as current when it satisfies any of the following criteria:
All other liabilities are classified as non-current. Deferred tax assets and liabilities are classified as non-current only. V. Acceptances The Group enters into arrangements whereby banks and financial institutions make direct payments to suppliers for raw materials and project materials. The banks and financial institutions are subsequently repaid by the Group at a later date providing working capital timing benefits. These are normally settled between twelve months (for raw materials) to thirty-six monthsthirty-six months, the economic substance of the transaction is determined to be financing in nature, and these are presented within borrowings in the consolidated statements of financial position. Interest expense on these are recognised as finance and other costs. Payments made by banks and financial institutions to the operating vendors are treated as an operational cash outflow and financing inflow and settlement of such acceptances by the Group is treated as a financing cash outflow. W. Cash and cash equivalents and restricted cash and cash equivalents Cash and cash equivalents comprise cash at bank and in hand, and short-term money market deposits which have a maturity of three months or less from the date of acquisition that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value and are unrestricted as to withdrawal and usage. For the purpose of the consolidated statement of cash flows, cash and cash equivalents consist of cash and short-term deposits, as defined above, and additionally includes unpaid dividend account. Restricted cash and cash equivalents in the consolidated statements of financial position comprise cash at bank and in hand, and short-term deposits which have a maturity of three months or less from the date of acquisition and are restricted as to withdrawal and usage. 3(b) Application of new and revised standards The Group has adopted, with effect from April 1, 2021, the following new and revised standards and interpretations. Their adoption did not had any material impact on the amounts reported in the consolidated financial statements.
Standards issued but not yet effective The new and amended standards that are issued, but not yet effective, up to the date of issuance of the Group’s financial statements are noted below:
The amendments are not expected to have a material impact on the Group. The Group has not early adopted any amendments which has been notified but is not yet effective. 3(c) Significant accounting estimates and judgements The preparation of consolidated financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions, that affect the application of accounting policies and the reported amounts of assets, liabilities, income, expenses and disclosures of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of revenues and expenses for the years presented. These judgments and estimates are based on management’s best knowledge of the relevant facts and circumstances, having regard to previous experience, but actual results may differ materially from the amounts included in the financial statements. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised and future periods affected. The information about significant areas of estimation uncertainty and critical judgements in applying accounting policies that have the most significant effect on the amounts recognised in the financial statements are as given below: I. Significant Estimates:
Exploration assets are assessed by comparing the carrying value to higher of fair value less cost of disposal or value in use if there are impairment indicators as contained in IFRS 6 ( Exploration for any Evaluation of Mineral resources Details of carrying values and impairment charge/ reversal and the assumptions used are disclosed in Note 14.
The Group has carried forward tax losses, unabsorbed depreciation and MAT credit that are available for offset against future taxable profit. Deferred tax assets are recognised only to the extent that it is probable that taxable profit will be available against which the unused tax losses or tax credits can be utilized. This involves an assessment of when those assets are likely to reverse, and a judgement as to whether or not there will be sufficient taxable profits available to offset the assets. This requires assumptions regarding future profitability, which is inherently uncertain. To the extent assumptions regarding future profitability change, there can be an increase or decrease in the amounts recognised in respect of deferred tax assets and consequential impact in the consolidated statements of profit or loss. Details of total deferred tax assets recognised in these financial statements including MAT credit entitlements are disclosed in Note 9.
TNPCB had issued a closure order of the Tuticorin Copper smelter, against which the Group had filed an appeal with the National Green Tribunal (“NGT”). NGT had, on August 8, 2013, ruled that the Copper smelter could continue its operations subject to implementation of recommendations of the Expert Committee appointed by the NGT. The TNPCB has filed an appeal against the order of the NGT before the Hon’ble Supreme Court of India. In the meanwhile, the application for renewal of Consent to Operate (“CTO”) for existing copper smelter was rejected by the TNPCB in April 2018. The Group has filed an appeal before the TNPCB Appellate Authority challenging the Rejection Order. During the pendency of the appeal, the TNPCB vide its order dated May 23, 2018 ordered closure of existing copper smelter plant with immediate effect. Further, the Government of Tamil Nadu issued orders on the same date with a direction to seal the existing copper smelter plant permanently. The Group believes these actions were not taken in accordance with the procedure prescribed under applicable laws. Subsequently, the Directorate of Industrial Safety and Health passed orders dated May 30, 2018 directing the immediate suspension and revocation of the Factory License and the Registration Certificate for the existing smelter plant. The Group appealed this before the NGT. NGT vide its order on December 15, 2018 has set aside the impugned orders and directed the TNPCB to pass fresh orders for renewal of consent and authorization to handle hazardous substances, subject to appropriate conditions for protection of environment in accordance with law. The State of Tamil Nadu and TNPCB approached the Hon’ble Supreme Court in Civil Appeals on January 2, 2019 challenging the judgement of the NGT dated December 15, 2018 and the previously passed judgement of NGT dated August 8, 2013. The Supreme Court vide its judgement dated February 18, 2019 set aside the judgements of NGT dated December 15, 2018 and August 8, 2013 solely on the basis of maintainability and directed the Group to file an appeal in High court. The Group had filed a writ petition before Madras High Court challenging the various orders passed against the Group in 2018 and 2013. On August 18, 2020, the Madras High Court delivered the judgement wherein it dismissed all the Writ Petitions filed by the Group. The Group has approached the Supreme Court and challenged the said High Court order by way of a Special Leave Petition (“SLP”) to Appeal and filed an interim relief for care & maintenance of the plant or trial run for certain period. The Matter was then listed on December 2, 2020 before the Supreme Court, which after having heard both sides concluded that at this stage the interim relief in terms of trial run could not be allowed. The hearing on care & maintenance could not be listed at the Supreme Court. Further, considering the voluminous nature of documents and pleadings, the matter shall be finally heard on merits. As per the Group’s assessment, it is in compliance with the applicable regulations and expects to get the necessary approvals in relation to the existing operations and hence the Group does not expect any material adjustments to these financial statements as a consequence of above actions. The Group has carried out an impairment analysis for existing plant assets during the year ended March 31, 2022 considering the key variables and concluded that there exists no impairment. The Group has done an additional sensitivity analysis with commencement of operations of the existing plant w.e.f. April 1, 2025 and noted that the recoverable amount of the assets would still be in excess of their carrying values. The carrying value of the assets as at March 31, ₹ ₹ Expansion Project: Separately, the Group filed a fresh application for renewal of the Environmental Clearance (EC) for the proposed Copper Smelter Plant 2 (Expansion Project) on March 12, 2018 before the Expert Appraisal Committee of the Ministry of Environment and Forests and Climate Change (“MoEFCC”) wherein a sub-committee was directed to visit the Expansion Project site prior to prescribing the Terms of Reference. In the meantime, the Madurai Bench of the High Court of Madras, in a Public Interest Litigation, held vide its order dated May 23, 2018 that the application for renewal of the EC for the Expansion Project shall be processed after a mandatory public hearing, and in the interim, ordered the Group to cease construction and all other activities on site for the proposed Expansion Project with immediate effect. The MoEFCC has delisted the expansion project since the matter is cancelled 342.22 sub-judice. Separately, State Industries Promotion Corporation of Tamil Nadu Ltd (“SIPCOT”) vide its letter dated May 29, 2018acres of the land allotted for the proposed Expansion Project. Further, the TNPCB issued orders on June 7, 2018 directing the withdrawal of the Consent to Establish (“CTE”) which was valid till March 31, 2023. The Group has approached the Madras High Court by way of writ petition challenging the cancellation of lease deeds by SIPCOT pursuant to which an interim stay has been granted. The Group has also filed Appeals before the TNPCB Appellate Authority challenging withdrawal of CTE by the TNPCB, the matter is pending for adjudication. Considering the delay in existing plant matter and delay in getting the required approval for expansion project, management has recorded a provision for impairment of ₹ f ₹ ₹ million) in fiscal years ending March 31, 2021 and as at March 31, 2022, respectively, approximating its recoverable value. Property, plant and equipment of ₹ ₹ material. On June 17, 2022, Board of Directors of the Company adopted a resolution to explore various options to potentially sell, in whole or in part, its Copper plant and associated facilities at Tuticorin. Accordingly, an Expression of Interest in this regard has been released on June 20, 2022. However, these evaluations are only exploratory in nature and no firm commitments have been executed at this stage.
Rajasthan Block The Group operates an oil and gas production facility in Rajasthan under a Production Sharing Contract (“PSC”). The management is of the opinion that the Group is eligible for an automatic extension of the PSC for Rajasthan (“RJ”) block on the same terms w.e.f. May 15, 2020 while Government of India (“GOI”), in October 2018, accorded its approval for extension of the PSC under the of 10 Pre-NELP Extension policy as per notification dated April 7, 2017 (“Pre-NELP Policy”) by a period years. As per the said policy and extension letter, the Group is required to comply with certain conditions and pay an % Profit Petroleum (“PP”) to GOI. The Group had challenged the applicability of the Pre NELP-Policy to the RJ block. The Division Bench of the Delhi High Court in March 2021 set aside the single judge order of May 2018 which allowed automatic extension of PSC. Nevertheless, GOI in their submissions to the Delhi High Court has not objected to Vedanta obtaining 10-year extension of RJ PSC. The legal dispute only relates to additional 10% PP rather than Vedanta’s right to obtain additional 1010-year extension. In the interim, without prejudice to the Group’s right, the Group has commenced paying the % PP claimed from May 15, 2020 to GoI. The Group has also filed an SLP in the Hon’ble Supreme Court against above Delhi High Court order and revised date for SLP listing is awaited. In parallel, the Group is in discussion with the ministry of petroleum and natural gas (“MoPNG”) on execution of a PSC addendum. One of the conditions for extension of PSC relates to notification of certain audit exceptions raised for FY 2016 -17 as per PSC provisions and provides for payment of amounts, if such audit exceptions result into any creation of liability. The Group had also clarified that the same should be de-linked as a condition for the extension which had been granted in October 2018. Discussions are ongoing to agree on the position that this issue will be dealt with as per ongoing arbitration with GOI as per PSC mechanism. The Directorate General of Hydrocarbons (“DGH”), in May 2018, has raised a demand on the Group and its subsidiary for the period up to March 31, 2017 for Government’s additional share of PP based on its computation of disallowance of cost incurred in excess of the initially approved Field Development Plan (“FDP”) of pipeline project for ₹ re-allocation of certain common costs between Development Areas (“DAs”) of RJ aggregating to ₹ re-allocation of certain common costs between DAs of RJ block of ₹ up to March 31, 2017. This amount was subsequently revised to ₹ On April 28, 2022, DGH has notified audit exceptions for the period up to May 14, 2020 and included an additional amount of US $ 259 million for above mentioned matters. Demand of US $ 202 million previously raised in May 2018 in respect of disallowance of costs incurred in excess of initially approved FDP of pipeline project has been removed as the revised pipeline project cost over the initial approved FDP was approved in September 2021. The Group believes that it has sufficient, as well as reasonable, basis pursuant to the PSC provisions and related approvals, supported by legal advice, for having claimed such costs and for allocating common costs between different DAs. In the Group’s opinion, these computations of the aforesaid demand / audit exceptions are not appropriate, and the accounting adjustments sought for issues pertaining to Year 2007 and onwards are based on assumptions that are not in consonance with the approvals already in place. The Group’s view is also supported by independent legal opinion and the Group has been following the process set out in PSC to resolve these aforesaid matters. The Group has also invoked the PSC process for resolution of disputed exceptions and has issued notice for arbitration and an arbitration tribunal (“Tribunal”) stands constituted. Further, on September 23, 2020, the GOI had filed an application for interim relief before Delhi High Court seeking payment of all disputed dues. The matter was heard on September 25, 2020 wherein the Delhi High Court has not passed any ex parte orders. The matter is now listed for hearing on August 29, 2022. Also, on Vedanta’s application under section 17 of the Arbitration and Conciliation Act, 1996, the Tribunal in December 2020 ordered that GOI should not take any action to enforce any of the amounts at issue in this arbitration against the Claimants (the Company and CIHL) during the arbitral period. The GOI has challenged the said order before the Delhi High Court under the said Act. This matter is also scheduled for hearing. The Group has also filed application under Sec 151 of Code of Civil Procedure (CPC) read with Section 9 of the Arbitration & Conciliation Act 1996 requesting Delhi High Court to direct GOI to extend the PSC for 10 years without insisting upon a payment of disputed dues under audit exceptions which have been already referred to arbitration. On April 12, 2022, basis the application, Delhi High Court has issued notice to GOI intimating application filed by the Group. The matter is yet to be heard. In management’s view, the above-mentioned condition on demand raised by the DGH for additional petroleum linked to PSC extension is untenable and has not resulted in creation of any liability and cannot be a ground for non-extension. In addition, all necessary procedures prescribed in the PSC including invocation of arbitration, in respect of the stated audit observation have also been fulfilled. Accordingly, the PSC extension approval granted vide DGH letter dated October 26, 2018 upholds with all conditions addressed and no material liability would devolve upon the Group. Simultaneously, the Group is also pursuing with the GOI for executing the RJ PSC addendum at the earliest. In view of extenuating circumstances surrounding COVID-19 and pending signing of the PSC addendum for extension after complying with all stipulated conditions, the GOI has been granting interim permission to the Group to continue Petroleum operations in the RJ block. The latest permission is valid up to August 14, 2022 or signing of the PSC addendum, whichever is earlier.
The Forest Advisory Committee (FAC) of MoEFCC granted the Stage 1 clearance and the MoEFCC approved the related Terms of Reference (“TOR”) on August 25, 2020. ESL presented its proposal before the Expert Appraisal Committee (“EAC”) after completing the public consultation process and the same has been recommended for grant of EC subject to Forest Clearance (“FC”) by the EAC in its 41st meeting dated July 29 and 30, 2021. Vide letter dated August 25, 2021, the MoEFCC rejected the EC “as of now” due to stay granted by Madras High Court vide order dated July 15, 2021 in a Public Interest Litigation filed against the Standard Operating Procedure which was issued by the MoEFCC for regularization of violation case on July 7, 2021. The Hon’ble Supreme Court of India vide order dated December 9, 2021 decided the matter by directing MoEFCC to process the EC application of ESL as per the applicable law within a period of three months. The MoEFCC vide its letter dated February 2, 2022 has deferred the grant of EC till FC Stage-II is granted to ESL. ESL has submitted its reply against the MoEFCC letter vide letter dated February 11, 2022 for reconsidering the decision of linking EC with FC as the grant of FC Stage-II is not a condition precedent for grant of EC. As per Stage 1 clearance, the Group is required to provide f non-forest land in addition to the afforestation cost. The Group, based on the report of an Environment Impact Assessment consultant, had recognised a provision o₹ million as part of cost of sales in the financial statements for the year ended March 31, 2021 with respect to the costs to be incurred by it for obtaining EC and additional ₹ ) has been provided against final order relating to wildlife conservation plan received during the current year.
Significant technical and commercial judgements are required to determine the Group’s estimated oil and natural gas reserves. Reserves considered for computing depletion are proved reserves for acquisition costs and proved and developed reserves for successful exploratory wells, development wells, processing facilities, distribution assets, estimated future abandonment cost and other related costs. Reserves for this purpose are considered on working interest basis which are reassessed at least annually. Changes in reserves as a result of change in management assumptions (see vii below) could impact the depreciation rates and the carrying value of assets (refer Note 14).
Management performs impairment tests on the Group’s developing/producing oil and gas assets where indicators of impairment are identified in accordance with IAS 36. The impairment assessments are based on a range of estimates and assumptions, including:
Any subsequent changes to cash flows due to changes in the above-mentioned factors could impact the carrying value of the assets. Details of carrying values and impairment charge and the assumptions used are disclosed in Note 14.
II. Significant Judgements:
The Group has ascertained that the Power Purchase Agreement (PPA) executed between one of the subsidiaries and a state grid qualifies to be an operating lease under IFRS 16. Accordingly, the consideration receivable under the PPA relating to recovery of capacity charges towards capital cost have been recognised as operating lease rentals and in respect of variable cost that includes fuel costs, operations and maintenance, etc. is considered as revenue from sale of products/services. Significant judgement is required in segregating the capacity charges due from the State grid between fixed and contingent payments. The Group has determined that since the capacity charges under the PPA are based on the number of units of electricity made available, which would be subject to variation on account of various factors like availability of coal and water for the plant, there are no fixed minimum payments under the PPA, which requires it to be accounted for on a straight line basis. The contingent rents recognised are disclosed in Note 6.
In the normal course of business, contingent liabilities may arise from litigation, taxation and other claims against the Group. A provision is recognised when the Group has a present obligation as a result of past events, and it is probable that the Group will be required to settle that obligation. 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 consolidated financial statements. When considering the classification of legal or tax cases as probable, possible or remote, there is judgement involved. This pertains to the application of the legislation, which in certain cases is based upon management’s interpretation of country specific applicable law, in particular India, and the likelihood of settlement. Management uses in-house and external legal professionals to make informed decision. Although there can be no assurance regarding the final outcome of the legal proceedings, the Group does not expect them to have a materially adverse impact on the Group’s financial position, profitability or cash flows. These are set out in Note 33.
In certain cases, the Group’s power customers are disputing various contractual provisions of PPA’s. Significant judgement is required in both assessing the tariff to be charged under the PPA in accordance with IFRS 15 and to assess the recoverability of withheld revenue currently accounted for as receivables. In assessing this critical judgment management, considered favourable external legal opinions the Group has obtained in relation to the claims and favourable court judgements in the related matter. In addition, the fact that the contracts are with government owned companies implies the credit risk is low. Refer Note 17. |

| Income tax expense | 9. Income tax expense Overview of the Indian direct tax regime Indian companies are subject to Indian income tax on a standalone basis. Each entity is assessed for tax on taxable profits determined for each financial year beginning on April 1 and ending on March 31. For each financial year, the respective entities’ profit or loss is subject to the higher of the regular income tax payable or the minimum alternative tax (“MAT”). Statutory income taxes are assessed based on book profits prepared under generally accepted accounting principles in India (“Indian GAAP”) adjusted in accordance with the provisions of the (Indian) Income tax Act, 1961. Such adjustments generally relate to depreciation of fixed assets, disallowances of certain provisions and accruals, deduction for tax holidays and similar exemptions, the use of tax losses carried forward and retirement benefit costs. Statutory income tax is charged at 30 % plus a surcharge and education cess. The combined Indian statutory tax rate for the financial years 34.94% and 25.17% 2019-20, 2020-21 and 2021-22 wasfor the subsidiaries who have opted new tax regime (refer Note 3(c) (I)( viii ). MAT is assessed on book profits adjusted for certain limited items as compared to the adjustments allowed for assessing regular income tax under normal provisions. MAT for financial years at 152019-20, 2020-21 and 2021-22 % plus surcharge and education cess. The combined Indian statutory tax rate of MAT for the financial years is 17.47%. MAT paid in excess of regular income tax during a year can be set off against regular income taxes within a period of fifteen years succeeding the assessment year in which MAT credit arises subject to the limits prescribed. 2019-20, 2020-21 and 2021-22 Business losses in India can be carried forward for a maximum period of eight assessment years immediately succeeding the assessment year to which the loss pertains. Unabsorbed depreciation can be carried forward for an indefinite period. Losses arising out of transfer of capital assets in India can be carried forward for a maximum period of eight assessment years immediately succeeding the assessment year to which the loss pertains. The carried forward long term capital losses can be set-off only against long term capital gains. Short term capital losses can be set off only against capital gains (which can be either long term or short-term capital gain). Income tax returns submitted by companies are regularly subjected to a comprehensive review and challenge by the tax authorities. There are appellate procedures available to both the tax authorities and taxpayers and it is not uncommon for significant or complex matters in dispute to remain outstanding for several years before they are finally resolved by the High Court or the Supreme Court. (a) Tax charge/ (credit) recognised in the consolidated statement of profit or loss
(b)
Certain businesses of the Group within India are eligible for specified tax incentives which are included in the table above as tax holidays and similar exemptions. Most of such tax exemptions are relevant for the companies operating in India. These are briefly described as under: The location based exemption In order to boost industrial and economic development in undeveloped regions, provided certain conditions are met, profits of newly established undertakings located in certain areas in India may benefit from tax holiday under section 80IC of the Income Tax Act, 1961. Such tax holiday works to exempt 100% of the profits for the first five years from the commencement of the tax holiday, and 30 % of profits for the subsequent five years. This deduction is available only for units established up to March 31, 2012. However, such undertaking would continue to be subject to MAT provisions. In the fiscal year ended March 31, 2021, undertaking at Pantnagar, which is part of HZL, was the only unit eligible for deduction at 30% of taxable profit. The location based exemption: SEZ Operations In order to boost industrial development and exports, provided certain conditions are met, profits of undertaking located in Special Economic Zone (‘SEZ’) may benefit from tax holiday. Such tax holiday works to exempt 100% of the profits for the first five years from the commencement of the tax holiday, 50% of profits for five years thereafter and 50 % of the profits for further five years provided the amount allowable in respect of deduction is credited to Special Economic Zone Re-Investment Reserve account. However, such undertaking would continue to be subject to MAT provisions. The Group has setup SEZ Operations in its aluminum division of Vedanta Limited where such benefit has been drawn. Sectoral Benefit—Power Plants and Port Operations To encourage the establishment of infrastructure, certain power plants and ports have been offered income tax exemptions of upto 100% of profits and gains for any ten consecutive years within the 15 year period following commencement of operations subject to certain conditions under section 80IA of the Income Tax Act, 1961. The Group currently has total operational capacity of 8.25 Giga Watts (GW) of thermal based power generation facilities and wind power capacity of 274 Mega Watts (MW) and port facilities. However, such undertakings would continue to be subject to MAT provisions. The Group has power plants which benefit from such deductions, at various locations of HZL, Vedanta Limited (where such benefits has been drawn), TSPL and BALCO (where no benefit has been drawn). Further tax incentives exist for certain other infrastructure facilities to exempt 100% of profits and gains for any ten consecutive years within the 20-year period following commencement of these facilities’ operation, provided certain conditions are met. HZL currently has certain eligible facilities. However, such facilities would continue to be subject to the MAT provisions. The Group operates a zinc refinery in Export Processing Zone, Namibia which has been granted tax exempt status by the Namibian government. In addition, the subsidiaries incorporated in Mauritius are eligible for tax credit to the extent of 80% of the applicable tax rate on foreign source income. The total effect of such tax holidays and exemptions was ₹ ₹ ₹ million) for the years ended March 31, 2020, March 31, 2021 and March 31, 2022, respectively. (c) Deferred tax assets/liabilities The Group has recorded significant amounts of deferred tax. The majority of the deferred tax liabilities represents accelerated tax relief for the depreciation of property plant and equipment, the depreciation of mining reserves and the fair value uplifts created on acquisitions, net of losses carried forward by the Group and unused tax credits in the form of MAT credits carried forward in the Group. Significant components of Deferred tax (assets) and liabilities recognized in the consolidated statement of financial position are as follows:
Deferred tax assets and liabilities have been offset where they arise in the same taxing jurisdiction with a legal right to offset income tax assets against income tax liabilities but not otherwise. Accordingly, the net deferred tax (assets)/liability has been disclosed in the consolidated statement of financial position as follows:
Deferred tax assets in the Group have been recognized to the extent there are sufficient taxable temporary differences relating to the same taxation authority and the same taxable entity which are expected to reverse. For certain components of the Group, deferred tax assets on carry forward unused tax losses have been recognised to the extent of deferred tax liabilities on taxable temporary differences available. It is expected that any reversals of the deferred tax liability would be offset against the reversal of the deferred tax asset at respective entities. Unused tax losses/ unused tax credit for which no deferred tax asset has been recognised amount to , ₹ ₹ , respectively. As at March 31, 2021
No deferred tax assets have been recognised on these unused tax losses/ unused tax credit as there is no evidence that sufficient taxable profit will be available in future against which these can be utilised by the respective entities. As at March 31, 2022
No deferred tax assets have been recognised on these unused tax losses/ unused tax credit as there is no evidence that sufficient taxable profit will be available in future against which these can be utilised by the respective entities. The Group has not recognised any deferred tax liabilities for taxes that would be payable on the Group’s share in unremitted earnings of certain of its subsidiaries because the Group controls when the liability will be incurred and it is probable that the liability will not be incurred in the foreseeable future. The amount of unremitted earnings is ₹ ₹ , respectively. (d) Non-current tax assets Non-current tax assets of ₹ ₹ , respectively, mainly represents income tax receivable from Indian tax authorities by Vedanta Limited relating to the refund arising consequent to the Scheme of Amalgamation & Arrangement made effective in August 2013 pursuant to approval by the jurisdiction High Court and receivables relating to matters in tax disputes in Group companies including tax holiday claim. (e) 09-10 to Assessment Year 12-13, the Commissioner of Income Tax (Appeals) has allowed these claims for Assessment Year 14-15 to Assessment Year 15-16, which were earlier disallowed and has granted refund of amounts deposited under protest. Against the Tribunal order, department had filed an appeal in Hon’ble Rajasthan High Court in financial year 17-18 which is yet to be admitted. As per the view of external legal counsel, tax department’s appeal seeks re-examination of facts rather than raising any substantial question of law and hence it is unlikely that appeal will be admitted by the High Court. Due to this, there is a high probability that the case will go in favor of the company. The amount involved in this dispute as of March 31, 2022 is ₹ ( $ 1,498 million) (March 31, 2021: ₹ |

i) Impairment reversal of ₹ block “RJ CGU” mainly due to increase in crude price forecast. Of this, ₹ ( $ 687 million) impairment reversal has been recorded against oil and gas producing facilities and ₹ reversal has been recorded against exploration and evaluation assets. The recoverable amount of the Group’s share in Rajasthan Oil and Gas cash generating unit “RJ CGU” was determined to be ₹ ) as at March 31, 2022. The recoverable amount of the RJ CGU was determined based on the fair value less costs of disposal approach, a level-3 valuation technique in the fair value hierarchy, as it more accurately reflects the recoverable amount based on the Group’s view of the assumptions that would be used by a market participant. This is based on the cash flows expected to be generated by the projected oil and natural gas production profiles up to the expected dates of cessation of production sharing contract (PSC)/cessation of production from each producing field based on the current estimates of reserves and risked resources. Reserves assumptions for fair value less costs of disposal tests consider all reserves that a market participant would consider when valuing the asset, which are usually broader in scope than the reserves used in a value-in-use post-tax nominal discount rate of 9.88% derived from the post-tax weighted average cost of capital after factoring in the risks ascribed to PSC extension including successful implementation of key growth projects. Based on the sensitivities carried out by the Group, change in crude price assumptions by US$ 1/bbl and changes to discount rate by 1% would lead to a change in recoverable value by ₹ ₹ , respectively. ii) Impairment reversal of ₹ KG-ONN-2003/1 increase in crude oil price forecast. The recoverable amount of the Group’s share in this CGU was determined to be ₹ post-tax nominal discount rate of 10.63%.

For oil & gas assets, CGU’s identified are on the basis of a production sharing contract (PSC) level, as it is the smallest group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or group of assets. The recoverable amount of the RJ CGU, ₹ level-3 valuation technique based on the cash flows expected to be generated by the projected oil and natural gas production profiles up to the expected dates of cessation of production sharing contract (PSC)/cessation of production from each producing field based on the current estimates of reserves and risked resources. Reserves assumptions for fair value less costs of disposal tests consider all reserves that a market participant would consider when valuing the asset, which are usually broader in scope than the reserves used in a value-in-use post-tax nominal discount rate of 10.35% derived from the post-tax weighted average cost of capital after factoring the risks ascribed to the successful implementation of key growth projects. Additionally, in computing the recoverable value, the effects of market participant’s response on production sharing contract matters have also been appropriately considered. Based on the sensitivities carried out by the Group, change in crude price assumptions by $ 1/bbl and changes to discount rate by 1% would lead to a change in recoverable value by ₹ ₹
The net recoverable value of assets and liabilities was assessed at ₹ ₹ ₹

| Financial instruments | 25. Financial instruments A. Financial assets and liabilities: The following tables present the carrying value and fair value of each category of financial assets and liabilities as at March 31, 2021 and March 31, 2022.
Fair value hierarchy The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:
The table below summarizes the categories of financial assets and liabilities as at March 31, 2021 and March 31, 2022 measured at fair value:
The table below summarizes the fair value of trade receivables, other non-current assets and borrowings which are carried at amortised cost as at March 31, 2020 and March 31, 2021:
The fair value of the financial assets and liabilities are at the amount that would be received to sell an asset and paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following methods and assumptions were used to estimate the fair values:
For all other financial instruments, the carrying amount is either the fair value or approximates the fair value. The changes in counterparty credit risk had no material effect on the hedge effectiveness assessment for derivatives designated in hedge relationship and the value of other financial instruments recognised at fair value. The estimated fair value amounts as at March 31, 2021 and March 31, 2022 have been measured as at that date. As such, the fair values of these financial instruments subsequent to reporting date may be different than the amounts reported at each year-end. There were no significant transfers between level 1, level 2 and level 3 during the current year. Risk management framework The Group’s businesses are subject to several risks and uncertainties including financial risks. The Group’s documented risk management polices act as an effective tool in mitigating the various financial risks to which the businesses are exposed to in the course of their daily operations. The risk management policies cover areas such as liquidity risk, commodity price risk, foreign exchange risk, interest rate risk, counterparty credit risk and capital management. Risks are identified at both the corporate and individual subsidiary level with active involvement of senior management. Each operating subsidiary in the Group has in place risk management processes which are in line with the Group’s policy. Each significant risk has a designated ‘owner’ within the Group at an appropriate senior level. The potential financial impact of the risk and its likelihood of a negative outcome are regularly updated. The risk management process is coordinated by the Management Assurance function and is regularly reviewed by the Group’s Audit Committee. The Audit Committee is aided by the other committees of the Board including the Risk Management Committee, which meets regularly to review risks as well as the progress against the planned actions. Key business decisions are discussed at the periodic meetings of the Executive Committee. The overall internal control environment and risk management programme including financial risk management is reviewed by the Audit Committee on behalf of the Board. The risk management framework aims to:
Treasury management Treasury management focuses on liability management, capital protection, liquidity maintenance and yield maximization. The treasury policies are approved by the Board. Daily treasury operations of the subsidiary companies are managed by their respective finance teams within the framework of the overall Group treasury policies. Long-term fund raising, including strategic treasury initiatives, are managed jointly by the business treasury team and the central team at corporate treasury while short-term funding for routine working capital requirements is delegated to subsidiary companies. A monthly reporting system exists to inform senior management of investments and debt position, exposure to currency, commodity and interest rate risk and their mitigants including the derivative position. The Group has adequate system of internal control which enables effective monitoring of adherence to Group’s policies. The internal control measures are effectively supplemented by regular internal audits. The Group uses derivative instruments to manage the exposure in foreign currency exchange rates, interest rates and commodity prices. The Group does not acquire or issue derivative financial instruments for trading or speculative purposes. The Group does not enter into complex derivative transactions to manage the treasury and commodity risks. Both treasury and commodities derivative transactions are normally in the form of forward contracts, interest rate and currency swaps and these are in line with the Group’s policies. Commodity price risk The Group is exposed to the movement of base metal commodity prices on the London Metal Exchange. Any decline in the prices of the base metals that the Group produces and sells will have an immediate and direct impact on the profitability of the businesses. As a general policy, the Group aims to sell the products at prevailing market prices. The commodity price risk in import of input commodity such as Copper Concentrate & Alumina, for our copper and aluminium business, is hedged on back-to back basis ensuring no price risk for the business. Hedging is used primarily as a risk management tool and, in some cases, to secure future cash flows in cases of high volatility by entering into forward contracts or similar instruments. The hedging activities are subject to strict limits set out by the Board and to a strictly defined internal control and monitoring mechanism. Decisions relating to hedging of commodities are taken at the Executive Committee level, basis clearly laid down guidelines. Whilst the Group aims to achieve average LME prices for a month or a year, average realised prices may not necessarily reflect the LME price movements because of a variety of reasons such as uneven sales during the year and timing of shipments. The Group is also exposed to the movement of international crude oil price and the discount in the price of Rajasthan crude oil to Brent price. Financial instruments with commodity price risk are entered into in relation to following activities:
Aluminum The requirement of the primary raw material, alumina, is partly met from own sources and the rest is purchased primarily on negotiated price terms. Sales prices are linked to the LME prices. At present, the Group, on selective basis hedges the aluminium content in outsourced alumina to protect its margins. The Group also executes hedging arrangements for its aluminium sales to realise average month of sale LME prices. Copper The Group’s custom smelting copper operations at Tuticorin is benefitted by a natural hedge except to the extent of a possible mismatch in quotational periods between the purchase of concentrate and the sale of finished copper. The Group’s policy on custom smelting is to generate margins from Treatment charges/Refining charges or “Tc/Rc”, improving operational efficiencies, minimising conversion cost, generating a premium over LME on sale of finished copper, sale of by-products and from achieving import parity on domestic sales. Hence, mismatches in quotational periods are managed to ensure that the gains or losses are minimised. The Group hedges this variability of LME prices through forward contracts and tries to make the LME price a pass-through cost between purchases of copper concentrate and sales of finished products, both of which are linked to the LME price. Tc/Rcs are a major source of income for the Indian copper smelting operations. Fluctuations in Tc/Rcs are influenced by factors including demand and supply conditions prevailing in the market for mine output. The Group’s copper business has a strategy of securing a majority of its concentrate feed requirement under long-term contracts with mines. Zinc, Lead and Silver The sales prices are linked to the LME prices. The Group also executes hedging arrangements for its Zinc, Lead and Silver sales to realise average month of sale LME prices. In exceptional circumstances, the Group may enter into strategic hedging with prior approval of the Board. Zinc International Raw material for zinc and lead is mined in South Africa with sales prices linked to the LME prices. Iron ore The Group sells its Iron Ore production from Goa on the prevailing market prices and from Karnataka through e-auction route as mandated by the State Government of Karnataka in India. Oil and gas The prices of various crude oils are based upon the price of the key physical benchmark crude oil such as Dated Brent, West Texas Intermediate, and Dubai/Oman, etc. The crude oil prices move based upon market factors like supply and demand. The regional producers price their crude basis these benchmavrk crude with a premium or discount over the benchmark based upon quality differential and competitiveness of various grades. The Group has started hedging variability of crude price for part of the volume through forward contracts. Natural gas markets are evolving differently in important geographical markets. There is no single global market for natural gas. This could be owing to difficulties in large-scale transportation over long distances as compared to crude oil. Globally, there are three main regional hubs for pricing of natural gas, which are USA (Henry Hub Prices), UK (NBP Price) and Japan (imported gas price, mostly linked to crude oil). Provisionally priced financial instruments The value of net financial liabilities linked to commodities (excluding derivatives) accounted for on provisional prices was ₹ ₹ , respectively. These instruments are subject to price movements at the time of final settlement and the final price of these instruments will be determined in the financial year beginning April 1, 2022. Set out below is the impact of 10% increase in LME prices on pre-tax profit/(loss) for the year and pre-tax equity as a result of changes in the value of the Group’s commodity financial instruments:
The above sensitivities are based on volumes, costs, exchange rates and other variables and provide the estimated impact of a change in LME prices on profit and equity assuming that all other variables remain constant. A 10% decrease in LME prices would have an equal and opposite effect on the Group’s financial statements. The impact on pre-tax profit/(loss) mentioned above includes the impact of a 10% increase in closing copper LME for provisionally priced copper concentrate purchased at Copper division custom smelting operations in India of ₹ ₹ s ended March 31, 2021 and March 31, 2022, respectively, which is a pass through in nature and as such will not have any impact on the profitability. Financial risk The Group’s Board approve s financial risk policies include monitoring, measuring and mitigating the liquidity, currency, interest rate and counterparty risk. The Group does not engage in speculative treasury activity but seeks to manage risk and optimize interest and commodity pricing through proven financial instruments. (a) Liquidity The Group requires funds both for short-term operational needs as well as for long-term investment programmes mainly in growth projects. The Group generates sufficient cash flows from the current operations which together with the available cash and cash equivalents short-term investments and structured investment net of deferred consideration payable for such investments provide liquidity both in the short-term as well as in the long-term. Anticipated future cash flows, together with undrawn fund based committed facilities of ₹ ₹ The Group has been rated by CRISIL Limited (CRISIL) and India Ratings and Research Private Limited (India Rating) for its capital market issuance in the form of CPs and NCDs and for its banking facilities in line with Basel II norms. CRISIL after revising the outlook to ‘Positive’ from ‘Stable’ in October 2021, upgraded its rating on the long-term bank facilities and debt instruments of Vedanta Limited to ‘CRISIL AA’ from ‘CRISIL AA-’ in February 2022. The outlook on ratings was also revised to ‘Stable’ from ‘Positive’. The short-term rating on bank facilities and commercial paper has been reaffirmed at ‘CRISIL A1+’. The upward rating action factors in stronger-than-expected operating profitability, driven by elevated commodity prices during fiscal year 2022, volume growth across businesses, and sustained cost efficiency, especially in the Aluminium business. India Rating also upgraded Vedanta Limited’s long term issuer ratings to “IND AA” from “IND AA-“with stable outlook on March 29, 2022. The rating upgrade reflects the Group’s continuous deleveraging and India ratings’ expectation of an improvement in the consolidated operational cash flow in financial year 2021-22 and financial year 2022-23, following a significant increase in the operating profitability, led by high metal prices partly offset by raw material input inflation. The Group remains committed to maintaining a healthy liquidity, a low gearing ratio and deleveraging and strengthening Group’s balance sheet . The maturity profile of the Group’s financial liabilities based on the remaining period from the balance sheet date to the contractual maturity date is given in the table below. The figures reflect the contractual undiscounted cash obligation of the Group:
The Group had access to following funding facilities:
Collateral The Group has pledged financial instruments with carrying amount of ₹ ₹ , respectively, and inventories with carrying amount of ₹ ₹ , respectively, as per the requirements specified in various financial facilities in place. The counterparties have an obligation to release the securities to the Group when financial facilities are surrendered. (b) Foreign currency risk Fluctuations in foreign currency exchange rates may have an impact on the consolidated statements of profit or loss, the consolidated statements of change in equity and consolidated statements of cash flows where any transaction references more than one currency or where assets/liabilities are denominated in a currency other than the functional currency of the respective consolidated entities. Considering the countries and economic environment in which the Group operates, its operations are subject to risks arising from the fluctuations primarily in the US dollar, Australian dollar, Namibian dollar, AED, ZAR, GBP, INR, JPY and Euro against the functional currencies of its Group. Exposures on foreign currency loans are managed through the Group wide hedging policy, which is reviewed periodically to ensure that the results from fluctuating currency exchange rates are appropriately managed. The Group strives to achieve asset, liability offset of foreign currency exposures and only the net position is hedged. The Group’s presentation currency is Indian Rupee. The majority of the assets are located in India and the Indian Rupee is the functional currency for the Indian operating subsidiaries except for Oil and Gas business. Natural hedges available in the business are identified at each entity level and hedges are placed only for the net exposure. Short-term net exposures are hedged progressively based on their maturity. A more conservative approach has been adopted for project expenditures to avoid budget overruns, where cost of the project is calculated taking into account the hedge cost. The hedge mechanisms are reviewed periodically to ensure that the risk from fluctuating currency exchange rates is appropriately managed. The following analysis is based on the gross exposure as at the reporting date which could affect the consolidated statements of profit or loss. The exposure summarised below is mitigated by some of the derivative contracts entered into by the Group as disclosed under the section on “Derivative financial instruments” The carrying amount of the Group’s financial assets and liabilities in different currencies are as follows:
The Group’s exposure to foreign currency arises where a Group company holds monetary assets and liabilities denominated in a currency different to the functional currency of that entity, with USD (US Dollar) being the major non-functional currency of the Group’s main operating subsidiaries. The foreign exchange rate sensitivity is calculated by the aggregation of the net foreign exchange rate exposure with a simultaneous parallel foreign exchange rates shift in the currencies by 10 % against the functional currencies of the respective entities. Set out below is the impact of a 10% strengthening in the functional currencies of the respective entities on pre-tax profit/(loss) and pre-tax equity arising as a result of the revaluation of the Group’s foreign currency monetary financial assets/liabilities:
A 10% weakening of the functional currencies of respective businesses would have an equal and opposite effect on the Group’s financial statements. (c) Interest rate risk The Group’s net debt of ₹ ₹ , respectively, comprises debt of ₹ ₹ , respectively, offset by cash, cash equivalents, short term investments of ₹ ₹ , respectively. The Group is exposed to interest rate risk on short-term and long-term floating rate instruments and on the refinancing of fixed rate debt. The Group’s policy is to maintain a balance of fixed and floating interest rate borrowings and the proportion of fixed and floating rate debt is determined by current market interest rates. The borrowings of the Group are principally denominated in Indian Rupees and US dollars with mix of fixed and floating rates of interest. The USD floating rate debt is linked to US dollar LIBOR and INR floating rate debt to Bank’s base rate. The Group has a policy of selectively using interest rate swaps, option contracts and other derivative instruments to manage its exposure to interest rate movements. These exposures are reviewed by appropriate levels of management on a monthly basis. The Group invests cash and liquid investments in short-term deposits and debt mutual funds, some of which generate a tax-free return, to achieve the Group’s goal of maintaining liquidity, carrying manageable risk and achieving satisfactory returns. Floating rate financial assets are largely mutual fund investments which have debt securities as underlying assets. The returns from these financial assets are linked to market interest rate movements; however, the counterparty invests in the agreed securities with known maturity tenure and return and hence has manageable risk. The exposure of the Group’s financial assets as at March 31, 2021 to interest rate risk is as follows:
The exposure of the Group’s financial liabilities as at March 31, 2021 to interest rate risk is as follows:
The exposure of the Group’s financial assets as at March 31, 2022 to interest rate risk is as follows:
The exposure of the Group’s financial liabilities as at March 31, 2022 to interest rate risk is as follows:
Considering the net debt position as at March 31, 2022 and the investment in bank deposits, corporate bonds and debt mutual funds, any increase in interest rates would result in a net loss and any decrease in interest rates would result in a net gain. The sensitivity analysis below has been determined based on the exposure to interest rates for financial instruments at the balance sheet date. The table below illustrates the impact of a 0.5% to 2.0% movement in interest rates on floating rate financial assets/ liabilities (net) on profit/(loss) and equity assuming that the changes occur at the reporting date and has been calculated based on risk exposure outstanding as of date. The year end balances are not necessarily representative of the average debt outstanding during the year. This analysis also assumes that all other variables, in particular foreign currency rates, remain constant.
An equivalent reduction in interest rates would have an equal and opposite effect on the Group’s financial statements. (d) Credit risk Credit risk refers to the risk that counterparty will default on its contractual obligations resulting in financial loss to the Group. The Group has adopted a policy of only dealing with creditworthy counterparties and obtaining sufficient collateral, where appropriate, as a means of mitigating the risk of financial loss from defaults. The Group is exposed to credit risk from trade receivables, contract assets, cash and cash equivalents, short term investments and other financial instruments. Credit risk on receivables is limited as almost all credit sales are against letters of credit and guarantees of banks of national standing. Moreover, given the diverse nature of the Group’s businesses , trade receivables are spread over a number of customers with no significant concentration of credit risk. The history of trade receivables shows a negligible provision for bad and doubtful debts. Therefore, the Group does not expect any material risk on account of non-performance by any of the Group’s counterparties. With respect to loans to related parties, as described in N ote 35(b), credit risk is adequately considered and no deterioration has happened or is expected to happen in the credit profile of the borrowers since the grant of the loans. Accordingly, the Group does not foresee any significant credit risk with respect to such loans. The Group has clearly defined policies to mitigate counterparty risks. For short-term investments, counterparty limits are in place to limit the amount of credit exposure to any one counterparty. This, therefore, results in diversification of credit risk for the Group’s mutual fund and bond investments. For derivative and financial instruments, the Group attempts to limit the credit risk by only dealing with reputable banks and financial institutions. The carrying value of the financial assets represents the maximum credit exposure. The Group’s maximum exposure to credit risk as at March 31, 2021 and March 31, 2022 is ₹ ₹ , respectively. The maximum credit exposure on financial guarantees given by the Group for various financial facilities is described in Note 33 on “Commitments, contingencies, and guarantees”. None of the Group’s cash equivalents, including time deposits with banks, are past due or impaired. Regarding trade and other receivables, and other non-current assets, there were no indications as at the year end that defaults in payment obligations will occur except as described in movement in allowance for impairment for financial assets given below. Of the year end trade and other receivables, the following are expected to be realised in the normal course of business and hence not considered impaired:
Receivables are deemed to be past due or impaired with reference to the Group’s normal terms and conditions of business. These terms and conditions are determined on a case to case basis with reference to the customer’s credit quality and prevailing market conditions. Receivables that are classified as ‘past due’ in the above table are those that have not been settled within the terms and conditions that have been agreed with that customer. The credit quality of the Group’s customers is monitored on an ongoing basis. Where receivables have been impaired, the Group actively seeks to recover the amounts in question and enforce compliance with credit terms. Movement in allowances for Financial Assets (trade and other receivables and other non-current assets)
Derivative financial instruments The Group uses derivative instruments as part of its management of exposure to fluctuations in foreign currency exchange rates, interest rates and commodity prices. The Group does not acquire or issue derivative financial instruments for trading or speculative purposes. The Group does not enter into complex derivative transactions to manage the treasury and commodity risks. Both treasury and commodities derivative transactions are normally in the form of forward contracts and these are subject to the Group guidelines and policies. The fair values of all derivatives are separately recorded in the consolidated statements of financial position within current and non-current assets and liabilities. Derivatives that are designated as hedges are classified as current or non-current depending on the maturity of the derivative. The use of derivatives can give rise to credit and market risk. The Group tries to control credit risk as far as possible by only entering into contracts with reputable banks and financial institutions. The use of derivative instruments is subject to limits, authorities and regular monitoring by appropriate levels of management. The limits, authorities and monitoring systems are periodically reviewed by management and the Board. The market risk on derivatives is mitigated by changes in the valuation of the underlying assets, liabilities or transactions, as derivatives are used only for risk management purposes. Cash flow hedges The Group enters into forward exchange and commodity price contracts for hedging highly probable forecast transaction and accounts for them as cash flow hedges and states them at fair value. Subsequent changes in fair value are recognized in the consolidated statements of comprehensive income until the hedged transaction occurs, at which time, the respective gain or losses are reclassified to the consolidated statements of profit or loss. These hedges have been effective for the year ended March 31, 2021 and March 31, 2022. The Group uses foreign exchange contracts from time to time to optimize currency risk exposure on its foreign currency transactions. The Group hedged part of its foreign currency exposure on capital commitments during the year ended 2022. Fair value changes on such forward contracts are recognized in the consolidated statements of comprehensive income. The majority of cash flow hedges taken out by the Group during the year comprise non-derivative hedging instruments for hedging the foreign exchange rate of highly probable forecast transactions and commodity price contracts for hedging the commodity price risk of highly probable forecast transactions. The cash flows related to these hedges are expected to occur during the year ended March 31, 2023 and consequently may impact the consolidated statements of profit or loss for that year depending upon the change in the commodity prices and foreign exchange rates movements. For cash flow hedges regarded as basis adjustments to initial carrying value of the property, plant and equipment, the depreciation on the basis adjustments made is expected to affect the consolidated statements of profit or loss over the expected useful life of the property, plant and equipment. Fair value hedges The fair value hedges relate to forward covers taken to hedge currency exposure and commodity price risks. The Group’s sales are on a quotational period basis, generally one month to three months after the date of delivery at a customer’s facility. The Group enters into forward contracts for the respective quotational period to hedge its commodity price risk based on average LME prices. Gains and losses on these hedge transactions are substantially offset by the amount of gains or losses on the underlying sales. Net gains and losses are recognized in the consolidated statements of profit or loss. The Group uses foreign exchange contracts from time to time to optimize currency risk exposure on its foreign currency transactions. Fair value changes on such forward contracts are recognized in the consolidated statements of profit or loss. Non-designated economic hedges The Group enters into derivative contracts which are not designated as hedges for accounting purposes, but provide an economic hedge of a particular transaction risk or a risk component of a transaction. Hedging instruments include copper, aluminium future contracts on the LME and certain other derivative instruments. Fair value changes on such derivative instruments are recognized in the consolidated statements of profit or loss. The fair value of the Group’s derivative positions recorded under derivative financial assets and derivative financial liabilities are as follows:

| Provisions | 26. Provisions
(a) 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 from a producing field. The provisions for restoration, rehabilitation and environmental liabilities represent the management’s best estimate of the costs which will be incurred in the future to meet the Group’s obligations under existing Indian, Australian, Namibian, South African and Irish law and the terms of the Group’s exploration and other licences and contractual arrangements. Within India, the principal restoration and rehabilitation provisions are recorded within Oil and Gas division where a legal obligation exists relating to the oil and gas fields and where costs are expected to be incurred in restoring the site of production facilities at the end of the producing life of an oil field. The Group recognises the full cost of site restoration as a liability when the obligation to rectify environmental damage arises. These amounts are calculated by considering discount rates within the range of 2% to 10% and become payable on closure of mines and are expected to be incurred over a period of to thirty years. The lower range of discount rate is at Oil and Gas and Zinc international operations in Ireland and higher range is at Zinc International operations in African c ountries. (b) Other provisions Other provisions include provision for disputed cases and claims. |

OI At the age of superannuation, contributions cease and the individual receives a monthly payment based on the level of contributions through the years, and on their salary scale at the time they retire, subject to a maximum ceiling of salary level. The GOI funds these payments, thus the Group has no additional liability beyond the contributions that it makes, regardless of whether the central fund is in surplus or deficit. Superannuation Superannuation, another pension scheme applicable in India, is applicable only to executives above certain grade. However, in case of oil and gas (applicable from the second year of employment) and Iron Ore segment, the benefit is applicable to all executives.

The Group expects to contribute ₹ P lan during the year ending March 31, 2023. Sensitivity analysis for defined benefit plans Below is the sensitivity analysis determined for significant actuarial assumptions for the determination of defined benefit obligations and based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period while holding all other assumptions constant.
The above sensitivity analysis may not be representative of the actual benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated. In presenting the above sensitivity analysis, the present value of defined benefit obligation has been calculated using the projected unit credit method at the end of reporting period, which is the same as that applied in calculating the defined obligation liability recognised in the consolidated statements of financial position. Risk analysis Group is exposed to a number of risks in the defined benefit plans. Most significant risks pertaining to defined benefits plans and management estimation of the impact of these risks are as follows: Investment risk Most of the Indian defined benefit plans are funded with LIC, ICICI and HDFC. The Group does not have any liberty to manage the funds provided to LIC, ICICI and HDFC. The present value of the defined benefit plan obligation is calculated using a discount rate determined by reference to GOI bonds for the Group’s Indian operations. If the return on plan asset is below this rate, it will create a plan deficit. Interest risk A decrease in the interest rate on plan assets will increase the net plan obligation. Longevity risk/ Life expectancy The present value of the defined benefit plan obligation is calculated by reference to the best estimate of the mortality of plan participants both during and at the end of the employment. An increase in the life expectancy of the plan participants will increase the plan obligation. Salary growth risk The present value of the defined benefit plan obligation is calculated by reference to the future salaries of plan participants. An increase in the salary of the plan participants will increase the plan obligation. Code on Social Security, 2020 The Code on Social Security, 2020 (‘Code’) relating to employee benefits during employment and post-employment benefits received Presidential assent in September 2020. The Code has been published in the Gazette of India. However, the date on which the Code will come into effect has not been notified and the final rules/interpretation have not yet been issued. The Group will assess the impact of the Code when it comes into effect and will record any related impact in the period the Code becomes effective. |

This fair value, adjusted by the Group’s estimate of the number of options that will eventually vest as a result of non-market conditions, is expensed over the vesting period. The fair value of cash settled options is measured initially and at each reporting date up to and including the settlement date, with changes in fair value recognised in employee benefits expense. Business Performance-Based and Sustained Individual Performance-Based Options: The fair value of stock options following these types of vesting conditions have been estimated using the Black-Scholes-Merton Option Pricing model. The value arrived at under this model has been then multiplied by the expected % vesting based on business performance conditions (only for business performance-based options) and the expected multiplier on account of sustained individual performance (for both type of options). The inputs used in the Black-Scholes-Merton Option Pricing model include the share price considered as of the valuation date, exercise price as per the scheme/ plan of the options, expected dividend yield (estimated based on actual/ expected dividend trend of the company), expected tenure (estimated as the remaining vesting period of the options), the risk-free rate (considered as the zero coupon yield as of the valuation date for a term commensurate with the expected tenure of the options) and expected volatility (estimated based on the historical volatility of the return in C ompany’s share prices for a term commensurate with the expected tenure of the options). The exercise period of 6 months post vesting period has not been considered as the options are expected to be exercised immediately post the completion of the vesting period. Total Shareholder Returns-Based Options: The fair value of stock options following this type of vesting condition has been estimated using the Monte Carlo Simulation method. This method has been used to simulate the expected share prices for Vedanta Limited and the companies of the comparator group over the vesting period of the options. Based on the simulated prices, the expected pay-off at the end of the vesting period has been estimated and present valued to the valuation date. Further, based on the simulated share prices and expected dividends, the relative rank of Vedanta Limited’s share price return has been estimated vis-à-vis C ompany’s share prices for a term commensurate with the expected tenure of the options). The exercise period of 6 months post the vesting period has not been considered as the options are expected to be exercised immediately post the completion of the vesting period. The assumptions used in the calculations of the charge in respect of the ESOS options granted during the year ended March 31, 2021 and March 31, 2022 are set out below:

The securities premium account may be applied by the Company towards the issue of unissued shares of the Company to the members of the Company as fully paid bonus shares, writing off the preliminary expenses of the Company, writing off the expenses of, or the commission paid or discount allowed on any issue of shares or debentures of the Company, providing for the premium payable on the redemption of any redeemable preference shares or of any debentures of the Company; or for the purchase of its own shares or other securities. Retained earnings includes amongst others, general reserve, debenture redemption reserve, preference share redemption reserve and capital reserve. General reserve Under the erstwhile Indian Companies Act, 1956, a general reserve was created through an annual transfer of net income at a specified percentage in accordance with applicable regulations. The purpose of these transfers was to ensure that if a dividend distribution in a given year is more than 10.0% of the paid-up capital of the Company for that year, then the total dividend distribution is less than the total distributable results for that year. Consequent to introduction of the Companies Act, 2013, the requirement to mandatory transfer a specified percentage of the net profit to general reserve has been withdrawn. The balance in general reserves, as determined in accordance with applicable regulations, was ₹ million) as at March 31, 2021 and March 31, 2022. The Board of Directors of the Company, basis the recommendations of the Audit & Risk Management Committee and Committee of Independent Directors of the Company, at its meeting held on October 29, 2021 approved the Scheme of Arrangement (“Scheme”) between the Company and its shareholders under Section 230 and other applicable provisions of the Companies Act, 2013. The Scheme inter alia provides for capital reorganization of the Company, whereby it is proposed to transfer amounts standing to the credit of the General Reserves to the Retained Earnings of the Company with effect from the Appointed Date. The Scheme is subject to receipt of regulatory approvals/ clearances from the Hon’ble National Company Law Tribunal, Mumbai Bench, Securities and Exchange Board of India (through BSE Limited and National Stock Exchange of India Limited), BSE Limited and National Stock Exchange of India Limited (collectively referred to as “Stock Exchanges”) and such other approvals/ clearances as may be applicable. Pursuant to the Scheme, the Company will possess greater flexibility to undertake capital related decisions and reflect a more efficient balance sheet. Debenture redemption reserve As per the earlier provision under the Indian Companies Act 2013 , companies that issue debentures were required to create debenture redemption reserve from annual profits until such debentures are redeemed. Companies were required to maintain 25% as a reserve of outstanding redeemable debentures. The amounts credited to the debenture redemption reserve may not be utilized except to redeem debentures. The MCA, vide its Notification dated August 16, 2019, had amended the Companies (Share Capital and Debenture) Rules, 2014, wherein the requirement of creation of Debenture Redemption Reserve has been exempted for certain class of companies, hence, in view of the same, the Company is not required to create Debenture Redemption Reserve. Retained earnings include ₹ ₹ of debenture redemption reserve as at March 31, 2021 and March 31, 2022 respectively. Preference share redemption reserve The Indian Companies Act 2013 provides that companies that issue preference shares may redeem those shares from profits of the Company which otherwise would be available for dividends, or from proceeds of a new issue of shares made for the purpose of redemption of the preference shares. If there is a premium payable on redemption, the premium must be provided, either by reducing the additional paid in capital (securities premium account) or out of profits, before the shares are redeemed. If profits are used to redeem preference shares, the value of the nominal amount of shares redeemed should be transferred from profits (retained earnings) to the preference share redemption reserve account. This amount should then be utilised for the purpose of redemption of redeemable preference shares. This reserve can be used to issue fully paid-up bonus shares to the shareholders of the Company. Retained earnings includes ₹ Capital reserve The balance in capital reserve as at March 31, 2021 and March 31, 2022 is
₹ ₹ , respectively. The balance in capital reserve has mainly arisen pursuant to extinguishment of non-controlling interests of erstwhile Cairn India Limited and acquisition of ASI. Further, changes in capital reserve are due to recognition/derecognition of put option liability and non-controlling interests pertaining to ASI. |

The Group has given bonds of D. Contingencies ₹ ₹ The Group discloses the following legal and tax cases as liabilities. Hindustan Zinc Limited: Department of Mines and Geology The Department of Mines and Geology of the State of Rajasthan issued several show cause notices to HZL in August, September and October 2006, aggregating to ₹ ₹ Ravva Joint Operations arbitration proceedings The Ravva Production Sharing Contract (PSC) obliges the contractor parties to pay a proportionate share of ONGC’s exploration, development, production and contract costs in consideration for ONGC’s payment of costs related to the construction and other activities it conducted in Ravva prior to the effective date of the Ravva PSC (the ONGC Carry). The question as to how the ONGC Carry is to be recovered and calculated, along with other issues, was submitted to an International Arbitration Tribunal in August 2002 which rendered a decision on the ONGC Carry in favour of the contractor parties (including Vedanta Limited (Cairn India Limited which subsequently merged with Vedanta Limited, accordingly now referred to as Vedanta Limited)) whereas four other issues were decided in favour of Government of India (GOI) in October 2004 (Partial Award). The GOI then proceeded to challenge the ONGC Carry decision before the Malaysian courts, as Kuala Lumpur was the seat of the arbitration. The Federal Court of Malaysia upheld the Partial Award. As the Partial Award did not quantify the sums, therefore, contractor parties approached the same Arbitration Tribunal to pass a Final Award in the subject matter since it had retained the jurisdiction to do so. The Arbitral Tribunal was reconstituted and the Final Award was passed in October 2016 in Vedanta Limited’s favour. GOI’s challenge of the Final Award has been dismissed by the Malaysian High Court and the next appellate court in Malaysia, i.e., Malaysian Court of Appeal. GOI then filed an appeal at Federal Court of Malaysia. The matter was heard on February 28, 2019 and the Federal Court dismissed GOI’s leave to appeal. The Company has also filed for the enforcement of the Partial Award and Final Award before the Hon’ble Delhi High Court. Currently, the matter is being heard. While the Group does not believe the GOI will be successful in its challenge, if the Arbitral Awards in above matters are reversed and such reversals are binding, the Company would be liable for approximately ₹ ₹ Proceedings related to the Imposition of Entry Tax Vedanta Limited and other Group companies, i.e., Bharat Aluminium Company Limited (BALCO) and Hindustan Zinc Limited (HZL) challenged the constitutional validity of the local statutes and related notifications in the states of Chhattisgarh, Odisha and Rajasthan pertaining to the levy of entry tax on the entry of goods brought into the respective states from outside. Post some contradictory orders of High Courts across India adjudicating on similar challenges, the Supreme Court referred the matters to a nine judge bench. Post a detailed hearing, although the bench rejected the compensatory nature of tax as a ground of challenge, it maintained status quo with respect to all other issues which have been left open for adjudication by regular benches hearing the matters. Following the order of the nine judge bench, the regular bench of the Supreme Court heard the matters. The regular bench remanded the entry tax matters relating to the issue of discrimination against domestic goods bought from other States to the respective High Courts for final determination but retained the issue of jurisdiction for levy on imported goods, for determination by the regular bench of the Supreme Court. Following the order of the Supreme Court, the Group filed writ petitions in respective High Courts. On October 9, 2017, the Supreme Court has held that states have the jurisdiction to levy entry tax on imported goods. With this Supreme Court judgement, imported goods will rank pari passu with domestic goods for the purpose of levy of Entry tax. Vedanta Limited and its subsidiaries have amended their appeals (writ petitions) in Odisha and Chhattisgarh to include imported goods as well. The issue pertaining to the levy of entry tax on the movement of goods into a Special Economic Zone (SEZ) remains pending before the Odisha High Court. The Group has challenged the levy of entry tax on any movement of goods into SEZ based on the definition of ‘local area’ under the Odisha Entry Tax Act which is very clear and does not include a SEZ. In addition, the Government of Odisha further through its SEZ Policy 2015 and the operational guidelines for administration of this policy dated August 22, 2016, exempted the entry tax levy on SEZ operations. During the current period, HZL has, under an Amnesty Scheme, settled the entry tax matter by making a payment of ₹ ₹ The total claims including interest and penalty against Vedanta Limited and its subsidiaries (net of provisions made) are ₹ million and ₹ million ($ 109 million) as at March 31, 2021 and March 31, 2022 respectively. Consequential interest after the date of order amounts to ₹ million and ₹ million ($ 70 million) as at March 31, 2021 and March 31, 2022 respectively. BALCO: Challenge against imposition of Energy Development Cess BALCO challenged the imposition of Energy Development Cess levied on generators and distributors of electrical energy at 10 paise per unit on the electrical energy sold or supplied before the High Court on the grounds that the Cess is effectively on production and not on consumption or sale since the figures of consumption are not taken into account and the Cess is discriminatory since captive power plants are required to pay at the rate of 10 paise while the State Electricity Board is required to pay at 5 paise. The High Court of Chhattisgarh by order dated December 15, 2006 declared the provisions imposing ED Cess on CPPs as discriminatory and therefore ultra vires the Constitution. BALCO has sought refund of Cess paid till March 2006 amounting to ₹ The State of Chhattisgarh moved a Special Leave Petition in the Honorable Supreme Court (the SC) and the SC whilst issuing notice has stayed the refund of the Cess already deposited and the Supreme Court has also directed the State of Chhattisgarh to raise the bills but no coercive action be taken for recovery of the same. Final argument in this matter started before the Supreme Court. In case the Supreme Court overturns the decision of the High Court, the Group would be liable to pay an additional amount of ₹ ₹ was ₹ ₹ BALCO: Electricity Duty The Group operates a 1,200 MW power plant (“the Plant”) which commenced production in July 2015. Based on the Memorandum of Understanding signed between the Group and the Chhattisgarh State Government, the management believes that the Plant is covered under the Chhattisgarh Industrial policy 2004-09 which provides exemption of electricity duty for 15 years.

| Other matters | 37. Other matters (a) i. Call option — HZL Pursuant to the Government of India’s policy of disinvestment, the Group in April 2002 acquired 26% equity interest in HZL from the Government of India. Under the terms of the Shareholder’s Agreement (‘SHA’), the Group had two call options to purchase all of the Government of India’s shares in HZL at fair market value. The Group exercised the first call option on August 29, 2003 and acquired an additional 18.9% of HZL’s issued share capital. The Group also acquired an additional 20% of the equity capital in HZL through an open offer, increasing its shareholding to 64.9%. The second call option provides the Group the right to acquire the Government of India’s remaining 29.5% share in HZL. This call option was subject to the right of the Government of India to sell 3.5% of HZL shares to HZL employees. The Group exercised the second call option on July 21, 2009. The Government of India disputed the validity of the call option and refused to act upon the second call option. Consequently, the Group invoked arbitration which is in the early stages. The next date of hearing is to be notified. The Government of India without prejudice to the position on the Put / Call option issue has received approval from the Cabinet for divestment and the Government is looking to divest through the auction route. Meanwhile, the Supreme Court had, in January 2016, directed status quo pertaining to disinvestment of Government of India’s residual shareholding in a public interest petition filed. On August 13, 2020, the Supreme Court passed an order partially removing the status quo order in place and has allowed the arbitration proceedings to continue via its order passed on November 18, 2021. The Supreme Court of India allowed the GoI’s proposal to divest its entire stake in HZL in the open market in accordance with the rules and regulations of SEBI and also directed the Central Bureau of Investigation to register a regular case in relation to the process followed for the disinvestment of HZL in the year 2002 by the GoI. A review petition has been filed by the GoI against this direction by the Supreme Court. In line with said order, the Group has withdrawn its arbitration proceedings. ii. Call option — BALCO Pursuant to the Government of India’s policy of divestment, the Group in March 2001 acquired 51% equity interest in BALCO from the Government of India. Under the terms of the Shareholder’s Agreement (‘SHA’), the Group had a call option to purchase the Government of India’s remaining ownership interest in BALCO at any point from March 2, 2004. The Group exercised this option on March 19, 2004. However, the Government of India contested the valuation and validity of the option and contended that the clauses of the SHA violate the erstwhile Companies Act, 1956 by restricting the rights of the Government of India to transfer its shares and that as a result such provisions of the SHA were null and void. In the arbitration filed by the Group, the arbitral tribunal by a majority award rejected the claims of the Group on the ground that the clauses relating to the call option, the right of first refusal, the “tag along” rights and the restriction on the transfer of shares violate the erstwhile Companies Act, 1956 and are not enforceable. The Group has challenged the validity of the majority award before the Hon’ble High Court at Delhi and sought for setting aside the arbitration award to the extent that it holds these clauses ineffective and inoperative. The Government of India also filed an application before the High Court to partially set aside the arbitral award in respect of certain matters involving valuation. The matter is to be heard by the Delhi High Court in due course. Meanwhile, the Government of India without prejudice to its position on the Put / Call option issue has received approval from the Cabinet for divestment and the Government is looking to divest through the auction route. On January 9, 2012, the Group offered to acquire the Government of India’s interests in HZL and BALCO for $ 2,071 and $ 238 respectively. This offer was separate from the contested exercise of the call options, and Group proposed to withdraw the ongoing litigations in relation to the contested exercise of the options should the offer be accepted. To date, the offer has not been accepted by the Government of India and therefore, there is no certainty that the acquisition will proceed. In view of the lack of resolution on the options, the non-response to the exercise and valuation request from the Government of India, the resultant uncertainty surrounding the potential transaction and the valuation of the consideration payable, the Group considers the strike price of the options to be at the fair value, which is effectively nil, and hence the call options have not been recognised in the financial statements. (b) The Scheme of Amalgamation and Arrangement amongst Sterlite Energy Limited (‘SEL’), Sterlite Industries (India) Limited (‘Sterlite’), Vedanta Aluminium Limited (‘VAL’), Ekaterina Limited (‘Ekaterina’), Madras Aluminium Company Limited (‘Malco’) and the Group (the “Scheme”) had been sanctioned by the Honorable High Court of Madras and the Honorable High Court of Judicature of Bombay at Goa and was given effect to in the year ended March 31, 2014. Subsequently the above orders of the Honorable High Court of Bombay and Madras have been challenged by Commissioner of Income Tax, Goa and Ministry of Corporate Affairs through a Special Leave Petition before the Honorable Supreme Court and also by a creditor and a shareholder of the Group. The said petitions are currently pending for hearing. (c) The Group purchases bauxite under long term linkage arrangement with Orissa Mining Corporation Ltd (hereafter referred as OMC) at provisional prices of ₹ The last successful e-auction based price discovery was done by OMC in April 2019 at ₹ September 2019 to September 2020 against an undertaking furnished by the Group to compensate any differential price discovered through future successful national e-auctions. Though the OMC conducted the next e-auction on August 31, 2020 with floor price of ₹ ₹ ₹ 1,707/MT. The Group had then filed a writ petition before Hon’ble High Court of Odisha in September 2020, which issued an interim o rder dated October 8, 2020 directing that the petitioner shall be permitted to lift the quantity of bauxite mutually agreed on payment of ₹ OMC re-conducted the e-auction on March 9, 2021 with floor price of ₹ ₹ 1000/M T will continue for the FY 2021-22. Further, on April 6, 2022, the honorable Cuttack High Court also continue for the FY 2022-23. Supported by legal opinions obtained, management believes that the provisions of Rule 45 are not applicable to commercial sale of bauxite ore and hence, it is not probable that the Group will have any financial obligation towards the aforesaid commitments over and above the price of ₹ e-auction. However, as an abundant precaution, the Group has recognized purchase of Bauxite from September 2019 onwards at the aforesaid rate of ₹ (d) The Department of Mines and Geology (DMG) of the State of Rajasthan initiated the royalty assessment process from Jan uar 2008 to 2019 and issued a show cause notice vide an office order dated January 31, 2020 amounting to y ₹ . Further an additional demand was issued vide an office order dated December 14, 2020 for ₹ million). The Group has challenged the show cause notice and computation mechanism of the royalty itself, and the High Court has granted a stay on the notice and directed DMG not to take any coercive action. State Government has also been directed to not take any coercive action in order to recover such miscomputed dues. The Group has filed a revision application for these demands and the Revenue Authority has granted stay on any recovery related to demand of ₹ (e) Flue-gas desulfurization (FGD) implementation: Ministry of Environment, Forest and Climate Change (MoEFCC) has revised emission norms for coal-based power plants in India. Accordingly, both captive and independent coal-based power plants in India are required to comply with these revised norms for reduction of sulphur oxide (SOx) emissions for which the current plant infrastructure is to be modified or new equipment have to be installed. Timelines for compliance to the revised norm for various plants in the Group range from December 2023 to December 2024. Different power plants are at different stages of the implementation process. Ministry of Power issued notification dated July 2, 2020 to restrict imports from China. A chinese vendor has communicated their inability to execute the FGD project quoting aforementioned notification and prevailing COVID situation in India. TSPL is proceeding with further steps for retendering the FGD project. TSPL filed a petition before the Punjab State Electricity Regulatory Commission (PSERC) for approval of MoEFCC notification as change in law in terms of Article 13 of PPA on June 30, 2017 enabling it to recover certain costs. PSERC vide its order dated December 21, 2018 has held that MoEFCC notification is not a change in law as it does not impose any new requirements. TSPL had filed an appeal before Hon’ble Appellate Tribunal for Electricity (APTEL) challenging the said order of PSERC. APTEL has pronounced the order August 28, 2020 in favour of TSPL allowing the cost pass through. PSPCL has filed an appeal against this order in Supreme Court. The matter was listed on February 03, 2022 wherein the SC issued notice and directed the respondents to file their respective counter affidavits in the matters. The matter is yet to be heard. (f) In December 2021,
MoEFCC has notified guidelines for thermal power plants for disposal of fly ash and bottom ash produced during power generation process. Effective April₹ million) as provision for the year ended March 31, 2022, towards estimated costs of legacy fly ash utilization including reclamation costs. |

| Supplementary Information on Oil and Gas Exploration and Production (Unaudited) | In accordance with Codification Topic 932 - Extractive Activities - Oil and gas, this section provides supplemental information on oil and gas exploration and producing activities of the Company for the years ended March 31, 2020, 2021 and 2022. The information included in items (i) through (iii) Method of accounting for costs incurred in oil and gas producing activities and manner of disposing of capitalized costs relating to those activities We follow a successful efforts based accounting policy for oil and gas assets. Costs incurred prior to obtaining the legal rights to explore an area are expensed immediately to the Consolidated statements of profit or loss. Expenditure incurred on the acquisition of a license interest is initially capitalised on a license by license basis. Costs are held, un-depleted, within intangible exploration/appraisal assets until such time as the exploration phase on the license area is complete or commercial reserves have been discovered. Exploration expenditure incurred in the process of determining oil and gas exploration targets is capitalised initially within intangible exploration/appraisal assets and subsequently allocated to drilling activities. Exploration/appraisal drilling costs are initially capitalised on well-by-well basis until the success or otherwise of the well has been established. The success or failure of each exploration/appraisal effort is judged on a well-by-well basis. Drilling costs are written off on completion of a well unless the results indicate that hydrocarbon reserves exist and there is a reasonable prospect that these reserves are commercial. Following appraisal of successful exploration wells, if commercial reserves are established and technical feasibility for extraction demonstrated, then the related capitalised intangible exploration/appraisal costs are transferred into a single field cost center within property, plant and equipment - development/producing assets after testing for impairment. Where results of exploration drilling indicate the presence of hydrocarbons which are ultimately not considered commercially viable, all related costs are written off to the Consolidated statements of profit or loss. All costs incurred after the technical feasibility and commercial viability of producing hydrocarbons has been demonstrated are capitalised within property, plant and equipment - development/producing assets on a field-by-field basis. Subsequent expenditure is capitalised only where it either enhances the economic benefits of the development/producing asset or replaces part of the existing development/producing asset. Any remaining costs associated with the part replaced are expensed. Net proceeds from any disposal of an intangible exploration/appraisal asset are initially credited against the previously capitalised costs. Any surplus proceeds are credited to the Consolidated statements of profit or loss. Net proceeds from any disposal of development/producing assets are credited against the previously capitalised cost. A gain or loss on disposal of a development/producing asset is recognised in the Consolidated statements of profit or loss to the extent that the net proceeds exceed or are less than the appropriate portion of the net capitalised costs of the asset. Capitalized costs relating to oil and gas producing activities The following table summarizes capitalized costs for oil and gas exploration and production activities with the related accumulated depreciation, depletion and amortization, and asset retirement obligation assets:
Costs incurred are summarized below and include both amounts expensed and capitalized:
* Figures in brackets ( ) represents reversal/ transfers between exploration and development costs.
The Company’s results of operations from oil and gas producing activities for the years ended March 31, 2022, 2021 and 2020 are shown in the following table. Production costs are lifting costs incurred to operate and maintain productive wells and related equipment and facilities, including operating employees’ compensation, materials, supplies, fuel consumed in operations and operating costs related to natural gas processing plants. Exploration expenses include the costs of geological and geophysical activities and non-productive exploratory wells. Depreciation and amortization expenses relate to assets employed in exploration and development activities. In accordance with Codification Topic 932 – Extractive Activities – Oil and gas, income taxes are based on statutory tax rates, reflecting allowable deductions. Till March 31, 2016, the Company had an effective tax rate lower than the statutory rate, benefiting from tax holiday in RJ Block under section 80-IB (9) of the Income Tax Act, 1961. Interest income and expense are excluded from the results reported in this table.
The following tables represent estimates for oil and gas reserves by geographic area as of March 31, 2022, 2021, and 2020. Quantities mentioned below represent proved developed and proved undeveloped reserves together with changes in quantities for the fiscal years 2022, 2021, and 2020. The definitions used for proved, proved developed and proved undeveloped oil and gas reserves are in accordance with United States Securities and Exchange Commission (SEC) Rule 4-10 of Regulation S-X. Proved oil and natural gas reserves are those estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be economically producible in future years from known reservoirs, under existing economic and operating conditions including a 12-month average price prior to the end of the reporting period, unless prices are defined by contract, and cost at the date of estimation. All the proved reserves presented herein are based on PSCs with the GoI. As such, all net reserves are based on an entitlement calculation which converts our share of cost recovery and profit petroleum under each contract to a volume equivalent of net reserves in accordance with SEC guidance on calculating net reserves subject to these agreements A summary of the annual changes in the proved reserves of oil is as follows (in mmbbls):
A summary of the annual changes in the proved reserves of natural gas is as follows (in bcf):
Year ending March 31, 2020 Total proved reserves as of March 31, 2019 were 142.72 mmboe. For the year ending March 31, 2020, total revisions of 12.47 mmboe were comprised of an increase of 8.94 mmboe based on technical revisions due to improved production performance and an increase of 3.53 mmboe due to revisions based on commodity prices. These total revisions comprised an increase of 0.06 mmboe for the Cambay block (CB/OS-2), a decrease of 0.16 mmboe for the Nagayalanka block (KG-ONN-2003/1), (RJ-ON-90/1), (PKGM-1). In fiscal year 2020, no revisions were made due to improved recovery. Extensions and discoveries of 0.04 mmboe were on account of inclusion of the Saraswati-4 Basement field which was approved for development in the RJ Block. After adjusting for the production of 31.35 mmboe, the total proved reserves as at March 31, 2020 were 123.88 mmboe. Year ending March 31, 2021 Total proved reserves as of March 31, 2020 were 123.88 mmboe. For the year ending March 31, 2021 total revisions of 23.01 mmboe comprised an increase of 9.66 mmboe based on technical revisions due to improved production performance and an increase of 13.35 mmboe due to revisions based on commodity prices. These total revisions comprised an increase of 0.51 mmboe for the Cambay block (CB/OS-2), no change for the Nagayalanka block (KG-ONN-2003/1), (RJ-ON-90/1), (PKGM-1). No revisions were made due to improved recovery. Extensions and discoveries of 0.67 mmboe were on account of inclusion of the NL and Raageshwari South-1 fields which were approved for development in the Rajasthan block. After adjusting for production of 24.96 mmboe, the total proved reserves as of March 31, 2021, were 122.60 mmboe. Year ending March 31, 2022 Total proved reserves as of March 31, 2021 were 122.60 mmboe. For the year ending March 31, 2022, total revisions of 12.66 mmboe were comprised of an increase of 7.33 mmboe based on technical revisions due to changes in production performance and a decrease of 19.99 mmboe due to revisions based on commodity prices. These total revisions were comprised of an increase of 0.55 mmboe for the Cambay block (CB/OS-2), an increase of 0.01 mmboe for the Nagayalanka block (KG-ONN-2003/1), (RJ-ON-90/1), (PKGM-1). No revisions were made due to improved recovery. Extensions and discoveries of 0.19 mmboe were on account of inclusion of the Hazarigaon field which was approved for development in the Hazarigaon block (AA-ONHP-2018/01). After adjusting for production of 22.46 mmboe, the total proved reserves as of March 31, 2022 were 87.66 mmboe.
The table below shows the standardized measure of future net cash flows relating to proved reserves. The analysis is computed in accordance with Topic 932 – Extractive Activities – Oil and gas, by applying average prices during the 12-month period prior to the ending date of the period covered by the report, determined as an un-weighted arithmetic average of the first-day-of-the-month year-end costs, fiscal year-end statutory tax rates and a discount factor of 10% to fiscal year-end quantities of net proved reserves. The standardized measure of discounted future net cash flows is a forward-looking statement. Future price changes are limited to those provided by existing contractual arrangements at the end of each reporting year. Future development and production costs are those estimated future expenditures necessary to develop and produce fiscal year-end estimated proved reserves based on fiscal year-end costs, assuming continuation of fiscal year-end economic conditions. Pre-tax future net cash flow is net of decommissioning and removal costs. Estimated future income taxes are calculated by applying the appropriate year-end statutory tax rates. These rates reflect allowable deductions and tax credits and are applied to estimated future pretax net cash flows, less the tax basis of related assets. We have an effective tax rate lower than the statutory rate, benefiting from tax holiday in RJ Block under section 80-IB (9) of the Income Tax Act, 1961.

| Basis of preparation | a) Basis of preparation These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”). These consolidated financial statements have been prepared in accordance with the accounting policies set out below and were consistently applied to all periods presented unless otherwise stated. These financial statements are approved for issue by the Board of Directors on August 1, 2022. Certain comparative figures appearing in these consolidated financial statements have been regrouped and/or reclassified to better reflect the nature of those items. The consolidated financial statements are presented in Indian Rupee (

| Basis of measurement | b) Basis of Measurement The consolidated financial statements have been prepared on a going concern basis using historical cost convention and on an accrual method of accounting, except for certain financial assets and liabilities which are measured at fair value as explained in the accounting policies below. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Restatement/Reclassification | c) Restatement/Reclassification In the comparative period ended March 31, 2021, some of the acceptances which were previously included under trade and other receivables and trade and other payables amounting to
₹ ₹ million, respectively, have been reclassified to acceptances on the face of the balance sheet. |

| Basis of consolidation | A. Basis of consolidation Subsidiaries: The consolidated financial statements incorporate the results of the Company and all its subsidiaries (the “Group”), being the entities that it controls. Control is evidenced where the Group has power over the investee, is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Power is demonstrated through existing rights that give the ability to direct relevant activities, which significantly affect the entity’s returns. The financial statements of subsidiaries are prepared for the same reporting year as the parent company. Where necessary, adjustments are made to the financial statements of subsidiaries to align the accounting policies in line with accounting policies of the Group. For non-wholly owned subsidiaries, a share of the profit/(loss) for the financial year and net assets is attributed to the non-controlling interests as shown in the consolidated financial statements. Liability for put option issued to non-controlling interests which do not grant present access to ownership interest to the Group is recognised at present value of the redemption amount and is reclassified from equity. At the end of each reporting period, the non-controlling interests subject to put option is derecognised and the difference between the amount derecognised and present value of the redemption amount, which is recorded as a financial liability, is accounted for as an equity transaction. For acquisitions of additional interests in subsidiaries, where there is no change in control, the Group recognises a reduction to the non-controlling interest of the respective subsidiary with the difference between this figure and the cash paid, inclusive of transaction fees, being recognised in equity. Similarly, upon dilution of controlling interests the difference between the cash received from sale or listing of the subsidiary shares and the increase to non-controlling interest is also recognised in equity. The results of subsidiaries acquired or disposed off during the year are included in the consolidated statements of profit or loss from the effective date of acquisition or up to the effective date of disposal, as appropriate. Intra-Group balances and transactions, and any unrealised profits arising from intra-Group transactions are eliminated. Unrealised losses are eliminated unless costs cannot be recovered. Joint arrangements A Joint arrangement is an arrangement of which two or more parties have joint control. Joint control is considered when there is contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Investments in joint arrangements are classified as either joint operations or joint venture. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement, have rights to the assets, and obligations for the liabilities relating to the arrangement. 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. The Group has both joint operations and joint ventures. Joint operations The Group has joint operations within its oil and gas segment. It participates in several unincorporated joint operations which involve the joint control of assets used in oil and gas exploration and producing activities. The Group accounts for its share of assets, liabilities, income and expenditure of joint operations in which the Group holds an interest. Liabilities in unincorporated joint operations where the Group is the operator are accounted for at gross values (including share of other partners) with a corresponding receivable from the venture partner. These have been included in the consolidated financial statements under the appropriate headings. Details of joint operations are set out in Note 34(b). Joint venture The Group accounts for its interest in joint venture using the equity method (see Note B below), after initially being recognised at cost in the consolidated statements of financial position. Goodwill arising on the acquisition of joint venture is included in the carrying value of investments in joint venture. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Investments in associates | B. Investments in associates: An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but, is not control or joint control over those policies. Investments in associates are accounted for using the equity method. Goodwill arising on the acquisition of associates is included in the carrying value of investments in associate. Equity method of accounting Under the equity method of accounting applicable for investments in associates and joint ventures, investments are initially recorded at the cost to the Group and then, in subsequent periods, the carrying value is adjusted to reflect the Group’s share of the post-acquisition profits or losses of the investee, the Group’s share of other comprehensive income of the investee, other changes to the investees net assets and is further adjusted for impairment losses, if any. Dividend received or receivable from associate and joint ventures are recognised as a reduction in carrying amount of the investment. The consolidated statements of profit or loss and consolidated statements of comprehensive income include the Group’s share of investee’s results, except where the investee is generating losses share of such losses in excess of the Group’s interest in that investee are not recognised. Losses recognised under the equity method in excess of the Group’s investment in ordinary shares are applied to the other components of the Group’s interest that forms part of Group’s net investment in the investee in the reverse order of their seniority (i.e., priority in liquidation). If the Group’s share of losses in an associate or joint venture equals or exceeds its interests in the associate or joint venture, the Group discontinues the recognition of further losses. Additional losses are provided for only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associate/ joint venture. Unrealised gains arising from transactions with associates and joint venture are eliminated against the investment to the extent of the Group’s interest in these entities. Unrealised losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment of the asset transferred. Accounting policies of equity accounted investees are changed where necessary to ensure consistency with the policies adopted by the Group. The carrying amount of equity accounted investments are tested for impairment in accordance with the policy described in Note 3 (a)(I) below. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Business combination | C. Business combinations Business combinations except those under common control are accounted for under the acquisition method. The acquiree’s identifiable assets, liabilities and contingent liabilities that meet the conditions for recognition under IFRS 3 (Business Combinations) Excess of fair value of purchase consideration and the acquisition date non-controlling interest over the acquisition date fair value of identifiable assets acquired and liabilities assumed is recognised as goodwill. Goodwill arising on acquisitions is reviewed for impairment annually. Where the fair values of the identifiable assets and liabilities exceed the purchase consideration, the Group re-assesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognised at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the surplus is credited to the consolidated statements of profit or loss in the period of acquisition. Where it is not possible to complete the determination of fair values by the date on which the first post-acquisition financial statements are approved, a provisional assessment of fair value is made and any adjustments required to those provisional fair values are finalised within 12 months of the acquisition date. Those provisional amounts are adjusted through goodwill during the measurement period, or additional assets or liabilities are recognised, or the amounts at which existing assets or liabilities were recorded are remeasured to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognised at that date. These adjustments are called as measurement period adjustments. The measurement period does not exceed twelve months from the acquisition date. Any non-controlling interest in an acquiree is measured at fair value or as the non-controlling interest’s proportionate share of the acquiree’s net identifiable assets. This accounting choice is made on a transaction by transaction basis. Acquisition expenses are charged to the consolidated statements of profit or loss. If the Group acquires a group of assets in a company that does not constitute a business combination in accordance with IFRS 3, the cost of the acquired group of assets is allocated to the individual identifiable assets acquired based on their relative fair value. Common control transactions A business combination involving entities or businesses under common control is a business combination in which all of the combining entities or businesses are ultimately controlled by the same party or parties both before and after the business combination and the control is not transitory. The transactions between entities under common control are scoped out of IFRS 3 and there is no authoritative literature for these transactions under IFRS. As a result, the Group adopted accounting principles similar to the pooling-of-interest |

| Revenue recognition | D. Revenue recognition Sale of products/ rendering of services (including revenue from contracts with customers) The Group’s revenue from contracts with customers is mainly from the sale of copper, aluminium, iron ore, zinc, oil and gas, power, steel, glass substrate and port operations. 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 Group 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 Group’s sales contracts provide for provisional pricing based on the price on the London Metal Exchange (LME) and crude index, 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 IFRS 9 ( Financial Instruments) (Revenue from Contracts with Customers) Revenue from oil, gas and condensate sales represent the Group’s share in the revenue from sale of such products, by the joint operations, and is recognised as and when control in these products gets transferred to the customers. In computing its share of revenue, the Group excludes government’s share of profit which gets accounted for when the obligation in respect of the same arises. Revenue from sale of power is recognised when delivered and measured based on rates as per bilateral contractual agreements with buyers and at a rate arrived at based on the principles laid down under the relevant Tariff Regulations as notified by the regulatory bodies, as applicable. Where the Group acts as a port operator, revenues relating to operating and maintenance phase of the port contract are measured at the amount that Group expects to be entitled to for the services provided. A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Group performs part of its obligation 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 the Group’s future performance. A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration from the customer. If a customer pays consideration before the Group transfers goods or services to the customer, a contract liability is recognised when the payment is received. The advance payments received, plus a specified rate of return/ discount at the prevailing market rates, are settled by supplying respective goods over a period of up to twenty four months under an agreed delivery schedule as per the terms of the respective agreements. As these are contracts that the Group expects and has the ability to fulfil through delivery of a non-financial item, these are presented as advance from customers and are recognised as revenue as and when control of respective commodities is transferred to customers under the agreements. The fixed rate of return/discount is treated as finance cost. The portion of the advance where either the Group does not have a unilateral right to defer settlement beyond 12 months or expects settlement within 12 months from the balance sheet date is classified as current liability. Interest income Interest income from debt instruments is recognised using the effective interest rate method. The effective interest rate is the rate that discounts estimated future cash receipts through the expected life of the financial asset to the gross carrying amount of a financial asset. When calculating the effective interest rate, the Group estimates the expected cash flows by considering all the contractual terms of the financial instrument (for example, prepayment, extension, call and similar options) but does not consider the expected credit losses. Dividends Dividend income is recognised in the consolidated statements of profit or 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 Group, and the amount of the dividend can be measured reliably. |

| Property, plant and equipment | E (a) Property, plant and equipment (i) Mining properties When a decision is taken that a mining properties is viable for commercial production (i.e., when the Group determines that the mining properties will provide sufficient and sustainable return relative to the risks and the Group decided to proceed with the mine development), all further pre-production primary development expenditure other than that on land, buildings, plant, equipment and capital work in progress is capitalized as property, plant and equipment under the heading “Mining properties” together with any amount transferred from “Exploration and evaluation” assets. The costs of mining properties include the costs of acquiring and developing mining properties. The stripping cost incurred during the production phase of a surface mine is deferred to the extent the current period stripping cost exceeds the average period stripping cost over the life of mine and recognised as an asset if such cost provides a benefit in terms of improved access to ore in future periods and certain criteria are met. When the benefit from the stripping costs is realized in the current period, the stripping costs are accounted for as the cost of inventory. If the costs of inventory produced and the stripping activity asset are not separately identifiable, a relevant production measure is used to allocate the production stripping costs between the inventory produced and the stripping activity asset. The Group uses the expected volume of waste compared with the actual volume of waste extracted for a given value of ore/mineral production for the purpose of determining the cost of the stripping activity asset. Deferred stripping costs are included in 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. In circumstances where a mining property is abandoned, the cumulative capitalised costs relating to the property are written off in the period in which it occurs, i.e., when the Group determines that the mining property will not provide sufficient and sustainable returns relative to the risks and the Group decides not to proceed with the mine development. Commercial reserves are proved and probable reserves as defined by the ‘JORC’ Code, ‘MORC’ code or ‘SAMREC’ Code. Changes in the commercial reserves affecting unit of production calculations are dealt with prospectively over the revised remaining reserves. (ii) Oil and gas assets- (developing/producing assets) For oil and gas assets a successful efforts based accounting policy is followed. Costs incurred prior to obtaining the legal rights to explore an area are expensed immediately to the consolidated statements of profit or loss. All costs incurred after the technical feasibility and commercial viability of producing hydrocarbons has been demonstrated are capitalised within property, plant and equipment—development/producing assets on a field-by-field Net proceeds from any disposal of development/producing assets are credited against the previously capitalised cost. A gain or loss on disposal of a development/producing asset is recognised in the consolidated statements of profit or loss to the extent that the net proceeds exceed or are less than the appropriate portion of the net capitalised costs of the asset. (iii) Other property, plant and equipment 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. If significant parts of an item of property, plant and equipment have different useful lives, then they are accounted for as separate items (major components) of property, plant and equipment. All other expenses on existing property, plant and equipment, including day-to-day Gains and losses on disposal of an item of property, plant and equipment, computed as the difference between the net disposal proceeds and the carrying amount of the asset, are included in the consolidated statements of profit or loss when the asset is derecognised. Major inspection and overhaul expenditure is capitalised, if the recognition criteria are met. (iv) Assets under construction Assets under construction are capitalised in the assets under construction 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 and any obligatory decommissioning costs are capitalised until the period of commissioning has been completed and the asset is ready for its intended use. Asset under construction are presented at cost, net of accumulated impairment losses, if any. (v) Depreciation, depletion and amortisation expense Mining properties and other assets in the course of development or construction, freehold land and goodwill are not depreciated or amortised. Mining properties The capitalised mining properties are amortised on a unit-of-production Oil and gas producing facilities All expenditures carried within each field are amortised from the commencement of production on a unit of production basis, which is the ratio of oil and gas production in the period to the estimated quantities of commercial reserves at the end of the period plus the production in the period, generally on a field-by-field Commercial reserves are proven and probable oil and gas reserves, which are defined as the estimated quantities of crude oil, natural gas and natural gas liquids which geological, geophysical and engineering data demonstrate with a specified degree of certainty to be recoverable in future years from known reservoirs and which are considered commercially producible. Costs used in the unit of production calculation comprise the net book value of capitalised costs plus the estimated future field development costs required to access the commercial reserves. Changes in the estimates of commercial reserves or future field development costs are recorded prospectively. The estimates of hydrocarbon reserves and resources have been derived in accordance with the Society of Petroleum Engineers “Petroleum Resources Management System (2018)”. Other assets Depreciation on property, plant and equipment is calculated using the straight-line method (SLM) to allocate their cost, net of their residual values, over their estimated useful lives (determined by the management) as given below. Management’s assessment takes into account, inter alia, the nature of the assets, the estimated usage of the assets, the operating conditions of the assets, past history of replacement and maintenance support. Estimated useful life of assets are as follows:
Major inspection and overhaul costs are depreciated over the estimated life of the economic benefit to be derived from such costs. The carrying amount of the remaining previous overhaul cost is charged to the consolidated statements of profit or loss if the next overhaul is undertaken earlier than the previously estimated life of the economic benefit. The Group reviews the residual value and useful life of an asset at least at each financial year end , and if expectations differ from previous estimates the change is accounted for as a change in accounting estimate. (b) Exploration and 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 which includes depreciation and applicable operating costs of related support equipment and facilities and other costs of exploration activities:
Exploration expenditure incurred in the process of determining oil and gas exploration targets is capitalised within “exploration and evaluation assets “and subsequently allocated to drilling activities. Exploration drilling costs are initially capitalised on a well-by-well well-by-well Following appraisal of successful exploration wells, if commercial reserves are established and technical feasibility for extraction demonstrated, then the related capitalised exploration costs are transferred into a single field cost centre within property, plant and equipment—development/ producing assets (oil and gas properties) after testing for impairment. Where results of exploration drilling indicate the presence of hydrocarbons which are ultimately not considered commercially viable, all related costs are written off to the consolidated statements of profit or loss. Expenditure incurred on the acquisition of a licence interest is initially capitalised on a licence-by-licence Net proceeds from any disposal of an exploration asset are initially credited against the previously capitalised costs. Any surplus/ deficit is recognised in the consolidated statements of profit or loss. (c) Other Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. Subsequently, intangibles assets are measured at cost less accumulated amortisation and accumulated impairment losses, if any. The Group recognises port concession rights as “Intangible Assets” arising from a service concession arrangement in which the grantor controls or regulates the services provided and the prices charged and also controls any significant residual interest in the infrastructure such as property, plant and equipment, irrespective whether the infrastructure is existing infrastructure of the grantor or the infrastructure is constructed or purchased by the Group as part of the service concession arrangement. Such an intangible asset is recognised by the Group initially at cost determined as the fair value of the consideration received or receivable for the construction service delivered and is capitalised when the project is complete in all respects. Port concession rights are amortised on straight line basis over the balance of license period. The concession period is 30 years from the date of the award. Any addition to the port concession rights are measured at fair value on recognition. Port concession rights also include certain property, plant and equipment in accordance with IFRIC 12 (Service Concession Arrangements) Intangible assets are amortised over their estimated useful life on a straight line basis. Software is amortised over the estimated useful life ranging from 2-5 years. Amounts paid for securing mining rights are amortised over the period of the mining lease ranging from 16-25 years. Technological know-how and acquired brand are amortised over the estimated useful life of ten years. 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 recognised in the consolidated statements of profit or loss when the asset is derecognised. The amortisation period and the amortisation method are reviewed at least at each financial year end. If the expected useful life of the asset is different from previous estimates, the change is accounted for prospectively as a change in accounting estimate. |

| Non-current assets held for sale | F. Non-current assets held for sale Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered through a sale transaction rather than through continuing use. This condition is regarded as met only when the sale is highly probable and the asset (or disposal group) is available for immediate sale in its present condition. Management must be committed to the sale which should be expected to qualify for recognition as a completed sale within one year from the date of classification. Non-current assets and disposal groups classified as held for sale are not depreciated and are measured at the lower of carrying amount and fair value less costs to sell. Such assets and disposal groups are presented separately on the face of the consolidated statements of financial position. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Financial instruments | G. 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. (a) Financial Assets – Recognition and subsequent measurement All financial assets are recognised initially at fair value plus, in the case of financial assets not recorded at fair value through profit or loss, transaction costs that are attributable to the acquisition of the financial asset. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognised on the trade date, i.e., the date that the Group commits to purchase or sell the asset. For purposes of subsequent measurement, financial assets are classified in four categories: Debt instruments at amortised cost A ‘debt instrument’ is measured at amortised cost if both the following conditions are met:
After initial measurement, such financial assets are subsequently measured at amortised cost using the Effective Interest Rate (EIR) method. Amortised 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 amortisation is included in interest income in consolidated statements of profit or loss. The losses arising from impairment are recognised in consolidated statements of profit or loss. Debt instruments at fair value through other comprehensive income (FVOCI) A ‘debt instrument’ is classified as at FVOCI if both of the following criteria are met:
Debt instruments included within the FVOCI category are measured initially, as well as at each reporting date, at fair value. Fair value movements are recognised in other comprehensive income (OCI). However, interest income, impairment losses and reversals and foreign exchange gain or loss are recognized in the consolidated statements of profit or loss. On derecognition of the asset, cumulative gain or loss previously recognised in other comprehensive income is reclassified from the equity to consolidated statements of profit or loss. Interest earned whilst holding fair value through other comprehensive income debt instrument is reported as interest income using the EIR method. Debt instruments at fair value through 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 amortised cost or as FVOCI is classified as FVTPL. In addition, the Group may elect to designate a debt instrument which otherwise meets amortised cost or FVOCI criteria as FVTPL. However, such election is allowed only if doing so reduces or eliminates a measurement or recognition inconsistency (referred to as ‘accounting mismatch’). Debt instruments included within the FVTPL category are measured at fair value with all changes being recognised in consolidated statement of profit or loss. The Group has not designated any debt instrument as FVTPL. Equity Instruments All equity investments in the scope of IFRS 9 are measured at fair value. Equity instruments which are held for trading and contingent consideration recognised by an acquirer in a business combination to which IFRS 3 applies are classified as at FVTPL. For all other equity instruments, the Group may make an irrevocable election to present in other comprehensive income any subsequent changes in the fair value. The Group makes such election on an instrument-by-instrument If the Group decides to classify an equity instrument as at FVOCI, then all fair value changes on the instrument, excluding dividends, are recognised in the OCI. There is no recycling of the amounts from OCI to profit or loss, even on sale of investment. However, the Group may transfer the cumulative gain or loss within equity. For equity instruments which are classified as FVTPL, all subsequent fair value changes are recognised in the consolidated statements of profit or loss. (b) Financial Assets—Derecognition The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. (c) Impairment of Financial Assets In accordance with IFRS 9, the Group applies expected credit loss (“ECL”) model for measurement and recognition of impairment loss on the following financial assets:
The Group follows the ‘simplified approach’ for recognition of impairment loss allowance on trade receivables, contract assets and lease receivables. The application of simplified approach does not require the Group 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. At each reporting date, for recognition of impairment loss on other financial assets and risk exposure, the Group 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 Group reverts to recognising impairment loss allowance based on 12-month ECL. Lifetime ECL is the expected credit loss 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 Group in accordance with the contract and all the cash flows that the entity expects to receive, discounted at the original EIR. ECL impairment (loss allowance)/reversal during the year is recognised as (expense)/income in the consolidated statements of profit or loss. The consolidated statements of financial position presentation for various financial instruments is described below:
For assessing increase in credit risk and impairment loss, the Group 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. The Group does not have any purchased or originated credit-impaired (POCI) financial assets, i.e., financial assets which are credit impaired on purchase/origination. (d) Financial Liabilities – Recognition and Subsequent measurement Financial liabilities are classified, at initial recognition, at fair value through profit or loss, or as loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial liabilities are recognised initially at fair value, and in the case of financial liabilities at amortised cost, net of directly attributable transaction costs. The Group’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts, financial guarantee contracts 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 Group that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. 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 recognised in the consolidated statements 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 IFRS 9 are satisfied. For liabilities designated as FVTPL, fair value gains/ losses attributable to changes in own credit risk are recognised in OCI. These gains/ losses are not subsequently transferred to consolidated statements of profit or loss. However, the Group may transfer the cumulative gain or loss within equity. All other changes in fair value of such liability are recognised in the consolidated statements of profit or loss. The Group has not designated any financial liability at fair value through profit or loss. Financial liabilities at amortised cost (Loans, Borrowings and Trade and Other payables) After initial recognition, interest-bearing loans and borrowings and trade and other payables are subsequently measured at amortised cost using the EIR method. Gains and losses are recognised in consolidated statements of profit or loss when the liabilities are derecognised as well as through the EIR amortisation process. Amortised 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 amortisation is included as finance and other costs in the consolidated statements of profit or loss. (e) Financial Liabilities – Derecognition A financial liability is derecognised 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 recognised in the consolidated statements of profit or loss. (f) 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 IFRS 9, the Group does not separate embedded derivatives. Rather, it applies the classification requirements contained in IFRS 9 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 recognised in the consolidated statements of profit or loss, unless designated as effective hedging instruments. (g) Equity Instruments An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments issued by the Group are recognised at the proceeds received, net of direct issue costs. (h) Offsetting of Financial Instruments Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability 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 Group enters into forward, option, swap contracts and other derivative financial instruments. The Group does not hold derivative financial instruments for speculative purposes. Such derivative financial instruments are initially recognised 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 the consolidated statements of profit or loss, except for the effective portion of cash flow hedges, which is recognised in OCI and later reclassified to the consolidated statements of 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:
At the inception of a hedge relationship, the Group formally designates and documents the hedge relationship to which the Group wishes to apply hedge accounting. The documentation includes the Group’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 Group 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 ongoing 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: (1) Fair value hedges Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognised in the consolidated statements of 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. When an unrecognised 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 recognised as an asset or liability with a corresponding gain or loss recognised in the consolidated statements of profit or loss. Hedge accounting is discontinued when the Group revokes the hedge relationship, the hedging instrument or hedged item expires or is sold, terminated, or exercised or no longer meets the criteria for hedge accounting and the unamortised fair value is recognised immediately in statement of profit or loss. (2) Cash flow hedges The effective portion of the gain or loss on the hedging instrument is recognised in OCI in the cash flow hedge reserve, while any ineffective portion is recognised immediately in the consolidated statements of profit or loss. Amounts recognised in OCI are transferred to the consolidated statements of profit or loss when the hedged transaction affects profit or loss, such as when the hedged financial income or financial expense is recognised or when a forecast sale occurs. When the hedged item is the cost of a non-financial asset or non-financial liability, the amounts recognised in 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 recognised in OCI remains separately in equity until the forecast transaction occurs or the foreign currency firm commitment is met. (3) Hedges of a net investment Hedges of a net investment in a foreign operation, including a hedge of a monetary item that is accounted for as part of the net investment, are accounted for in a way similar to cash flow hedges. Gains or losses on the hedging instrument relating to the effective portion of the hedge are recognised in OCI while any gains or losses relating to the ineffective portion are recognised in the consolidated statements of profit or loss. On disposal of the foreign operation, the cumulative value of any such gains or losses recorded in equity is reclassified to the consolidated statements of profit or loss. |

| Borrowing costs | H. Borrowing costs Borrowing cost includes interest expense as per EIR and exchange differences arising from foreign currency borrowings to the extent they are regarded as an adjustment to the interest cost. Borrowing costs directly relating to the acquisition, construction or production of a qualifying capital project under construction are capitalised and added to the project cost during construction until such time that the assets are substantially ready for their intended use, i.e., when they are capable of commercial production. Borrowing costs relating to the construction phase of a service concession arrangement is capitalised as part of the cost of the intangible asset. Where funds are borrowed specifically to finance a qualifying capital project, the amount capitalised represents the actual borrowing costs incurred. Where surplus funds are available out of money borrowed specifically to finance a qualifying capital project, the income generated from such short-term investments is deducted from the total capitalised borrowing cost. If any specific borrowing remains outstanding after the related asset is ready for its intended use or sale, that borrowing then becomes part of general borrowing. Where the funds used to finance a project form part of general borrowings, the amount capitalised is calculated using a weighted average of rates applicable to relevant general borrowings of the Group during the year. All other borrowing costs are recognised in the consolidated statements of profit or loss in the year in which they are incurred. Capitalisation of interest on borrowings related to construction or development projects is ceased when substantially all the activities that are necessary to make the assets ready for their intended use are complete or when delays occur outside of the normal course of business. EIR is the rate that discounts the estimated future cash payments or receipts over the expected life of the financial liability or a shorter period, where appropriate, to the amortised cost of a financial liability. When calculating the effective interest rate, the Group estimates the expected cash flows by considering all the contractual terms of the financial instrument (for example, prepayment, extension, call and similar options). |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Impairment | I. Impairment 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. The Group assesses at each reporting date, whether there is an indication that an asset may be impaired. The Group 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 recognised impairment losses. Internal and external factors, such as worse economic performance than expected, changes in expected future prices, costs and other market factors are also monitored to assess for indications of impairment or reversal of previously recognised impairment losses. If any such indication exists or in case of goodwill where annual testing of impairment is required, then an impairment review is undertaken and 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 Group and not applicable to entities in general. Fair value for mineral and oil and gas 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 Group’s continued use and do not 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. The carrying value is net of deferred tax liability recognised in the fair value of assets acquired in the business combination. 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 and impairment loss is recognised in the consolidated statements of profit or loss. Any reversal of the previously recognised 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 recognised except if initially attributed to goodwill. Exploration and evaluation assets: In assessing whether there is any indication that an exploration and evaluation asset may be impaired, the Group considers, as a minimum, the following indicators:
When a potential impairment is identified, an assessment is performed for each area of interest in conjunction with the group of operating assets (representing a cash-generating unit) to which the exploration and evaluation assets is attributed. Exploration areas in which reserves have been discovered but require major capital expenditure before production can begin, are continually evaluated to ensure that commercial quantities of reserves exist or to ensure that additional exploration work is under way or planned. To the extent that capitalised expenditure is no longer expected to be recovered, it is charged to the consolidated statements of profit or loss. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Leases | J. Leases The Group assesses at contract inception, all arrangements to determine whether they are, or contain, a lease i.e., if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. (a) Group as a lessor Leases in which the Group 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 recognised 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 recognised over the lease term on the same basis as rental income. Contingent rents are recognised as revenue in the period in which they are earned. Leases are classified as finance leases when substantially all of the risks and rewards of ownership transfer from the Group to the lessee. Amounts due from lessees under finance leases are recorded as receivables at the Group’s net investment in the leases. Finance lease income is allocated to accounting periods so as to reflect a constant periodic rate of return on the net investment outstanding in respect of the lease. (b) Group as a lessee The Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognises lease liabilities towards future lease payments and right-of-use (i) Right-of-use The Group recognises right-of-use Right-of-use right-of-use right-of-use Right-of-use (ii) Lease liabilities At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (in some instances, in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognised as expenses (unless they are incurred to produce inventories) in the period in which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is generally not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. The Group’s lease liabilities are included in trade and other payables. (iii) Short-term leases and leases of low-value assets The Group applies the short-term lease recognition exemption to its short-term leases of equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low-value assets are recognised as expense on a straight-line basis over the lease term. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Government grants | K. Government grants Grants and subsidies from the government are recognised when there is reasonable assurance that (i) the Group 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 recognised as income on a systematic basis in the consolidated statements of profit or loss over the periods necessary to match them with the related costs which they are intended to compensate. Government grants relating to tangible fixed assets are deducted in calculating the carrying amount of the assets and recognised in the consolidated statements of profit or loss over the expected useful lives of the respective assets as reduced depreciation expense. 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 recognised 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. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Inventories | L. Inventories Inventories and work-in-progress Cost is determined on the following basis:
Net realisable value is determined based on estimated selling price, less further costs expected to be incurred for completion and disposal. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Taxation | M. Taxation Tax expense represents the sum of current tax and deferred tax. Current tax is provided at amounts expected to be paid (or recovered) using the tax rates and laws that have been enacted or substantively enacted by the reporting date and includes any adjustment to tax payable in respect of previous years. Subject to the exceptions below, 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 and on carry forward of unused tax credits and unused tax losses:
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realised 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 recognised outside the consolidated statements of profit or loss is recognised either in other comprehensive income or equity. The carrying amount of deferred tax assets (including MAT credit entitlement) is reviewed at each reporting date and is adjusted to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the asset to be recovered. Unrecognised deferred tax assets are re-assessed at each reporting date and are recognised 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 deferred tax liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. Deferred tax is provided on temporary differences arising on acquisitions that are categorised as Business Combinations. Deferred tax is recognised at acquisition as part of the assessment of the fair value of assets and liabilities acquired. Subsequently deferred tax is charged or credited in the consolidated statements of profit or loss/other comprehensive income as the underlying temporary difference is reversed. Further, management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group reflects the effect of uncertainty for each uncertain tax treatment by using either most likely method or expected value method, depending on which method predicts better resolution of the treatment. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Retirement benefits schemes | N. Retirement benefit schemes The Group operates or participates in a number of defined benefit and defined contribution schemes, the assets of which (where funded) are held in separately administered funds. For defined benefit schemes, the cost of providing benefits under the plans is determined by actuarial valuation each year, separately for each plan, using the projected unit credit method by third party qualified actuaries. Remeasurements , including effects of asset ceiling and return on plan assets (excluding amounts included in interest on the net defined benefit liability) and actuarial gains and losses arising in the year, are recognised in full in other comprehensive income and are not recycled to the consolidated statements of profit or loss. Past service costs are recognised in the consolidated statements of profit or loss on the earlier of:
Net interest is calculated by applying a discount rate to the net defined benefit liability or asset at the beginning of the period. Defined benefit costs are split into current service cost, past service cost, net interest expense or income and remeasurement, and gains and losses on curtailments and settlements. Current service cost and past service costs are recognised within cost of sales and administrative expenses and distribution expenses. Net interest expense or income is recognised within finance and other costs. For defined contribution schemes, the amount charged to the consolidated statements of profit or loss in respect of pension costs and other post-retirement benefits is the contributions payable in the year, recognised as and when the employee renders related services. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Share based payments | O. Share-based payments Certain employees (including executive directors) of the Group receive part of their remuneration in the form of share-based payment transactions, whereby employees render services in exchange for shares or rights over shares (‘equity-settled transactions’). The cost of equity-settled transactions with employees is measured at fair value of share awards at the date at which they are granted. The fair value of share awards is determined with the assistance of an external valuer and the fair value at the grant date is expensed on a proportionate basis over the vesting period based on the Group’s estimate of shares that will eventually vest. The estimate of the number of awards likely to vest is reviewed at each reporting date up to the vesting date at which point the estimate is adjusted to reflect the current expectations. The resultant increase in equity is recorded in share-based payment reserve. In case of cash-settled transactions, a liability is recognised for the fair value of cash-settled transactions. The fair value is measured initially and at each reporting date up to and including the settlement date, with changes in fair value recognised in employee benefits expense. The fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The fair value is determined with the assistance of an external valuer. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Provisions, contingent liabilities and contingent assets | P. Provisions, contingent liabilities and contingent assets The assessments undertaken in recognising provisions and contingencies have been made in accordance with the applicable IFRS. Provisions represent liabilities for which the amount or timing is uncertain. Provisions are recognised when the Group 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 recognised in the consolidated statements of profit or loss as finance and other costs. Provisions are reviewed at each reporting date and are adjusted to reflect the current best estimate. A contingent liability is a possible obligation that arises from past events whose existence will be confirmed by the occurrence or non-occurrence of one or more uncertain future events beyond the control of the Group or a present obligation that is not recognised because it is not probable that an outflow of resources will be required to settle the obligation. A contingent liability also arises in extremely rare cases where there is a liability that cannot be recognised because it cannot be measured reliably. In certain situations, the Group does not recognise a contingent liability but discloses its existence in the consolidated financial statements. Contingent assets are not recognised but disclosed in the financial statements when an inflow of economic benefit is probable. The Group has significant capital commitments in relation to various capital projects which are not recognised in the consolidated statements of financial position. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Restoration, rehabilitation and environmental costs | Q. 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 or oil fields. Such costs, discounted to net present value, are provided for and a corresponding amount is capitalised at the start of each project as soon as the obligation to incur such costs arises. These costs are charged to the consolidated statements of profit or loss over the life of the operation through the depreciation of the asset and the unwinding of the discount on the provision. The cost estimates are reviewed periodically and are adjusted to reflect known developments which may have an impact on the cost estimates or life of operations. 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. The unwinding of the discount is shown as finance and other costs in the consolidated statements of profit or loss. Costs for the restoration of subsequent site damage which is caused on an ongoing basis during production are provided for at their net present value and charged to the consolidated statements of profit or loss as extraction progresses. Where the costs of site restoration are not anticipated to be material, they are expensed as incurred. |

| Accounting for foreign currency transactions and translations | R. Accounting for foreign currency transactions and translations The functional currency for each entity in the Group is determined as the currency of the primary economic environment in which it operates. For all principal operating subsidiaries, the functional currency is normally the local currency of the country in which it operates with the exception of oil and gas business operations which have US dollar functional currency as that is the currency of the primary economic environment in which it operates. In the financial statements of individual group companies, transactions in currencies other than the respective functional currencies are translated into their functional currencies at the exchange rates ruling at the date of the transaction. Monetary assets and liabilities denominated in other currencies are translated into functional currencies 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 consolidated statements of profit or loss except those where the monetary item is designated as an effective hedging instrument of the currency risk of designated forecasted sales or purchases, which are recognised in the other comprehensive income. Exchange differences which are regarded as an adjustment to interest costs on foreign currency borrowings are capitalised as part of borrowing costs in qualifying assets. For the purposes of the consolidation of financial statements, items in the consolidated statements of profit or loss of those businesses for which the Indian Rupees is not the functional currency are translated into Indian Rupees at the average rates of exchange during the year/ exchange rates as on the date of transaction. The related consolidated statements of financial position is translated into Indian rupees at the rates as at the reporting date. Exchange differences arising on translation are recognised in the consolidated statements of other comprehensive income. On disposal of such entities the deferred cumulative exchange differences recognised in equity relating to that particular foreign operation are recognised in the consolidated statements of profit or loss. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings per share | S. Earnings per share The Group 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 potentially dilutive equity shares. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Treasury Shares | T. Treasury shares The Group has created an Employee Benefit Trust (EBT) for providing share-based payment to its employees. The Group uses EBT as a vehicle for distributing shares to employees under the employee remuneration schemes. The EBT buys shares of the Company from the market for giving shares to employees. The shares held by EBT are treated as treasury shares. Own equity instruments that are reacquired (treasury shares) are recognised at cost and deducted from equity. No gain or loss is recognised in profit or loss on the purchase, sale, issue or cancellation of the Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognised in equity. Share options, whenever exercised, are satisfied with treasury shares. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Current and non-current classification | U. Current and non-current classification The Group presents assets and liabilities in the consolidated statements of financial position based on current / non-current classification. An asset is classified as current when it satisfies any of the following criteria:
All other assets are classified as non-current. A liability is classified as current when it satisfies any of the following criteria:
All other liabilities are classified as non-current. Deferred tax assets and liabilities are classified as
non-current only. |
|||||||||||||||||||||||||||||||||||||||||||||||||
| Acceptances | V. Acceptances The Group enters into arrangements whereby banks and financial institutions make direct payments to suppliers for raw materials and project materials. The banks and financial institutions are subsequently repaid by the Group at a later date providing working capital timing benefits. These are normally settled between twelve months (for raw materials) to
thirty-six monthsthirty-six months, the economic substance of the transaction is determined to be financing in nature, and these are presented within borrowings in the consolidated statements of financial position. Interest expense on these are recognised as finance and other costs. Payments made by banks and financial institutions to the operating vendors are treated as an operational cash outflow and financing inflow and settlement of such acceptances by the Group is treated as a financing cash outflow. |

| Cash and cash equivalents and restricted cash and cash equivalents | W. Cash and cash equivalents and restricted cash and cash equivalents Cash and cash equivalents comprise cash at bank and in hand, and short-term money market deposits which have a maturity of three months or less from the date of acquisition that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value and are unrestricted as to withdrawal and usage. For the purpose of the consolidated statement of cash flows, cash and cash equivalents consist of cash and short-term deposits, as defined above, and additionally includes unpaid dividend account. Restricted cash and cash equivalents in the consolidated statements of financial position comprise cash at bank and in hand, and short-term deposits which have a maturity of three months or less from the date of acquisition and are restricted as to withdrawal and usage. |

| Significant accounting estimates and judgements | 3(c) Significant accounting estimates and judgements The preparation of consolidated financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions, that affect the application of accounting policies and the reported amounts of assets, liabilities, income, expenses and disclosures of contingent assets and liabilities at the date of these consolidated financial statements and the reported amounts of revenues and expenses for the years presented. These judgments and estimates are based on management’s best knowledge of the relevant facts and circumstances, having regard to previous experience, but actual results may differ materially from the amounts included in the financial statements. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised and future periods affected. The information about significant areas of estimation uncertainty and critical judgements in applying accounting policies that have the most significant effect on the amounts recognised in the financial statements are as given below: I. Significant Estimates:
Exploration assets are assessed by comparing the carrying value to higher of fair value less cost of disposal or value in use if there are impairment indicators as contained in IFRS 6 ( Exploration for any Evaluation of Mineral resources Details of carrying values and impairment charge/ reversal and the assumptions used are disclosed in Note 14.
The Group has carried forward tax losses, unabsorbed depreciation and MAT credit that are available for offset against future taxable profit. Deferred tax assets are recognised only to the extent that it is probable that taxable profit will be available against which the unused tax losses or tax credits can be utilized. This involves an assessment of when those assets are likely to reverse, and a judgement as to whether or not there will be sufficient taxable profits available to offset the assets. This requires assumptions regarding future profitability, which is inherently uncertain. To the extent assumptions regarding future profitability change, there can be an increase or decrease in the amounts recognised in respect of deferred tax assets and consequential impact in the consolidated statements of profit or loss. Details of total deferred tax assets recognised in these financial statements including MAT credit entitlements are disclosed in Note 9.
TNPCB had issued a closure order of the Tuticorin Copper smelter, against which the Group had filed an appeal with the National Green Tribunal (“NGT”). NGT had, on August 8, 2013, ruled that the Copper smelter could continue its operations subject to implementation of recommendations of the Expert Committee appointed by the NGT. The TNPCB has filed an appeal against the order of the NGT before the Hon’ble Supreme Court of India. In the meanwhile, the application for renewal of Consent to Operate (“CTO”) for existing copper smelter was rejected by the TNPCB in April 2018. The Group has filed an appeal before the TNPCB Appellate Authority challenging the Rejection Order. During the pendency of the appeal, the TNPCB vide its order dated May 23, 2018 ordered closure of existing copper smelter plant with immediate effect. Further, the Government of Tamil Nadu issued orders on the same date with a direction to seal the existing copper smelter plant permanently. The Group believes these actions were not taken in accordance with the procedure prescribed under applicable laws. Subsequently, the Directorate of Industrial Safety and Health passed orders dated May 30, 2018 directing the immediate suspension and revocation of the Factory License and the Registration Certificate for the existing smelter plant. The Group appealed this before the NGT. NGT vide its order on December 15, 2018 has set aside the impugned orders and directed the TNPCB to pass fresh orders for renewal of consent and authorization to handle hazardous substances, subject to appropriate conditions for protection of environment in accordance with law. The State of Tamil Nadu and TNPCB approached the Hon’ble Supreme Court in Civil Appeals on January 2, 2019 challenging the judgement of the NGT dated December 15, 2018 and the previously passed judgement of NGT dated August 8, 2013. The Supreme Court vide its judgement dated February 18, 2019 set aside the judgements of NGT dated December 15, 2018 and August 8, 2013 solely on the basis of maintainability and directed the Group to file an appeal in High court. The Group had filed a writ petition before Madras High Court challenging the various orders passed against the Group in 2018 and 2013. On August 18, 2020, the Madras High Court delivered the judgement wherein it dismissed all the Writ Petitions filed by the Group. The Group has approached the Supreme Court and challenged the said High Court order by way of a Special Leave Petition (“SLP”) to Appeal and filed an interim relief for care & maintenance of the plant or trial run for certain period. The Matter was then listed on December 2, 2020 before the Supreme Court, which after having heard both sides concluded that at this stage the interim relief in terms of trial run could not be allowed. The hearing on care & maintenance could not be listed at the Supreme Court. Further, considering the voluminous nature of documents and pleadings, the matter shall be finally heard on merits. As per the Group’s assessment, it is in compliance with the applicable regulations and expects to get the necessary approvals in relation to the existing operations and hence the Group does not expect any material adjustments to these financial statements as a consequence of above actions. The Group has carried out an impairment analysis for existing plant assets during the year ended March 31, 2022 considering the key variables and concluded that there exists no impairment. The Group has done an additional sensitivity analysis with commencement of operations of the existing plant w.e.f. April 1, 2025 and noted that the recoverable amount of the assets would still be in excess of their carrying values. The carrying value of the assets as at March 31, ₹ ₹ Expansion Project: Separately, the Group filed a fresh application for renewal of the Environmental Clearance (EC) for the proposed Copper Smelter Plant 2 (Expansion Project) on March 12, 2018 before the Expert Appraisal Committee of the Ministry of Environment and Forests and Climate Change (“MoEFCC”) wherein a sub-committee was directed to visit the Expansion Project site prior to prescribing the Terms of Reference. In the meantime, the Madurai Bench of the High Court of Madras, in a Public Interest Litigation, held vide its order dated May 23, 2018 that the application for renewal of the EC for the Expansion Project shall be processed after a mandatory public hearing, and in the interim, ordered the Group to cease construction and all other activities on site for the proposed Expansion Project with immediate effect. The MoEFCC has delisted the expansion project since the matter is cancelled 342.22 sub-judice. Separately, State Industries Promotion Corporation of Tamil Nadu Ltd (“SIPCOT”) vide its letter dated May 29, 2018acres of the land allotted for the proposed Expansion Project. Further, the TNPCB issued orders on June 7, 2018 directing the withdrawal of the Consent to Establish (“CTE”) which was valid till March 31, 2023. The Group has approached the Madras High Court by way of writ petition challenging the cancellation of lease deeds by SIPCOT pursuant to which an interim stay has been granted. The Group has also filed Appeals before the TNPCB Appellate Authority challenging withdrawal of CTE by the TNPCB, the matter is pending for adjudication. Considering the delay in existing plant matter and delay in getting the required approval for expansion project, management has recorded a provision for impairment of ₹ f ₹ ₹ million) in fiscal years ending March 31, 2021 and as at March 31, 2022, respectively, approximating its recoverable value. Property, plant and equipment of ₹ ₹ material. On June 17, 2022, Board of Directors of the Company adopted a resolution to explore various options to potentially sell, in whole or in part, its Copper plant and associated facilities at Tuticorin.

However, these evaluations are only exploratory in nature and no firm commitments have been executed at this stage.
Rajasthan Block The Group operates an oil and gas production facility in Rajasthan under a Production Sharing Contract (“PSC”). The management is of the opinion that the Group is eligible for an automatic extension of the PSC for Rajasthan (“RJ”) block on the same terms w.e.f. May 15, 2020 while Government of India (“GOI”), in October 2018, accorded its approval for extension of the PSC under the of 10 Pre-NELP Extension policy as per notification dated April 7, 2017 (“Pre-NELP Policy”) by a period years. As per the said policy and extension letter, the Group is required to comply with certain conditions and pay an % Profit Petroleum (“PP”) to GOI. The Group had challenged the applicability of the Pre NELP-Policy to the RJ block. The Division Bench of the Delhi High Court in March 2021 set aside the single judge order of May 2018 which allowed automatic extension of PSC. Nevertheless, GOI in their submissions to the Delhi High Court has not objected to Vedanta obtaining 10-year extension of RJ PSC. The legal dispute only relates to additional 10% PP rather than Vedanta’s right to obtain additional 1010-year extension. In the interim, without prejudice to the Group’s right, the Group has commenced paying the % PP claimed from May 15, 2020 to GoI. The Group has also filed an SLP in the Hon’ble Supreme Court against above Delhi High Court order and revised date for SLP listing is awaited. In parallel, the Group is in discussion with the ministry of petroleum and natural gas (“MoPNG”) on execution of a PSC addendum. One of the conditions for extension of PSC relates to notification of certain audit exceptions raised for FY 2016 -17 as per PSC provisions and provides for payment of amounts, if such audit exceptions result into any creation of liability. The Group had also clarified that the same should be de-linked as a condition for the extension which had been granted in October 2018. Discussions are ongoing to agree on the position that this issue will be dealt with as per ongoing arbitration with GOI as per PSC mechanism. The Directorate General of Hydrocarbons (“DGH”), in May 2018, has raised a demand on the Group and its subsidiary for the period up to March 31, 2017 for Government’s additional share of PP based on its computation of disallowance of cost incurred in excess of the initially approved Field Development Plan (“FDP”) of pipeline project for ₹ re-allocation of certain common costs between Development Areas (“DAs”) of RJ aggregating to ₹ re-allocation of certain common costs between DAs of RJ block of ₹ up to March 31, 2017. This amount was subsequently revised to ₹ On April 28, 2022, DGH has notified audit exceptions for the period up to May 14, 2020 and included an additional amount of US $ 259 million for above mentioned matters. Demand of US $ 202 million previously raised in May 2018 in respect of disallowance of costs incurred in excess of initially approved FDP of pipeline project has been removed as the revised pipeline project cost over the initial approved FDP was approved in September 2021. The Group believes that it has sufficient, as well as reasonable, basis pursuant to the PSC provisions and related approvals, supported by legal advice, for having claimed such costs and for allocating common costs between different DAs. In the Group’s opinion, these computations of the aforesaid demand / audit exceptions are not appropriate, and the accounting adjustments sought for issues pertaining to Year 2007 and onwards are based on assumptions that are not in consonance with the approvals already in place. The Group’s view is also supported by independent legal opinion and the Group has been following the process set out in PSC to resolve these aforesaid matters. The Group has also invoked the PSC process for resolution of disputed exceptions and has issued notice for arbitration and an arbitration tribunal (“Tribunal”) stands constituted. Further, on September 23, 2020, the GOI had filed an application for interim relief before Delhi High Court seeking payment of all disputed dues. The matter was heard on September 25, 2020 wherein the Delhi High Court has not passed any ex parte orders. The matter is now listed for hearing on August 29, 2022. Also, on Vedanta’s application under section 17 of the Arbitration and Conciliation Act, 1996, the Tribunal in December 2020 ordered that GOI should not take any action to enforce any of the amounts at issue in this arbitration against the Claimants (the Company and CIHL) during the arbitral period. The GOI has challenged the said order before the Delhi High Court under the said Act. This matter is also scheduled for hearing. The Group has also filed application under Sec 151 of Code of Civil Procedure (CPC) read with Section 9 of the Arbitration & Conciliation Act 1996 requesting Delhi High Court to direct GOI to extend the PSC for 10 years without insisting upon a payment of disputed dues under audit exceptions which have been already referred to arbitration. On April 12, 2022, basis the application, Delhi High Court has issued notice to GOI intimating application filed by the Group. The matter is yet to be heard. In management’s view, the above-mentioned condition on demand raised by the DGH for additional petroleum linked to PSC extension is untenable and has not resulted in creation of any liability and cannot be a ground for non-extension. In addition, all necessary procedures prescribed in the PSC including invocation of arbitration, in respect of the stated audit observation have also been fulfilled. Accordingly, the PSC extension approval granted vide DGH letter dated October 26, 2018 upholds with all conditions addressed and no material liability would devolve upon the Group. Simultaneously, the Group is also pursuing with the GOI for executing the RJ PSC addendum at the earliest. In view of extenuating circumstances surrounding COVID-19 and pending signing of the PSC addendum for extension after complying with all stipulated conditions, the GOI has been granting interim permission to the Group to continue Petroleum operations in the RJ block. The latest permission is valid up to August 14, 2022 or signing of the PSC addendum, whichever is earlier.
The Forest Advisory Committee (FAC) of MoEFCC granted the Stage 1 clearance and the MoEFCC approved the related Terms of Reference (“TOR”) on August 25, 2020. ESL presented its proposal before the Expert Appraisal Committee (“EAC”) after completing the public consultation process and the same has been recommended for grant of EC subject to Forest Clearance (“FC”) by the EAC in its 41st meeting dated July 29 and 30, 2021. Vide letter dated August 25, 2021, the MoEFCC rejected the EC “as of now” due to stay granted by Madras High Court vide order dated July 15, 2021 in a Public Interest Litigation filed against the Standard Operating Procedure which was issued by the MoEFCC for regularization of violation case on July 7, 2021. The Hon’ble Supreme Court of India vide order dated December 9, 2021 decided the matter by directing MoEFCC to process the EC application of ESL as per the applicable law within a period of three months. The MoEFCC vide its letter dated February 2, 2022 has deferred the grant of EC till FC Stage-II is granted to ESL. ESL has submitted its reply against the MoEFCC letter vide letter dated February 11, 2022 for reconsidering the decision of linking EC with FC as the grant of FC Stage-II is not a condition precedent for grant of EC. As per Stage 1 clearance, the Group is required to provide f non-forest land in addition to the afforestation cost. The Group, based on the report of an Environment Impact Assessment consultant, had recognised a provision o₹ million as part of cost of sales in the financial statements for the year ended March 31, 2021 with respect to the costs to be incurred by it for obtaining EC and additional ₹ ) has been provided against final order relating to wildlife conservation plan received during the current year.
Significant technical and commercial judgements are required to determine the Group’s estimated oil and natural gas reserves. Reserves considered for computing depletion are proved reserves for acquisition costs and proved and developed reserves for successful exploratory wells, development wells, processing facilities, distribution assets, estimated future abandonment cost and other related costs. Reserves for this purpose are considered on working interest basis which are reassessed at least annually. Changes in reserves as a result of change in management assumptions (see vii below) could impact the depreciation rates and the carrying value of assets (refer Note 14).
Management performs impairment tests on the Group’s developing/producing oil and gas assets where indicators of impairment are identified in accordance with IAS 36. The impairment assessments are based on a range of estimates and assumptions, including:
Any subsequent changes to cash flows due to changes in the above-mentioned factors could impact the carrying value of the assets. Details of carrying values and impairment charge and the assumptions used are disclosed in Note 14.
II. Significant Judgements:
The Group has ascertained that the Power Purchase Agreement (PPA) executed between one of the subsidiaries and a state grid qualifies to be an operating lease under IFRS 16. Accordingly, the consideration receivable under the PPA relating to recovery of capacity charges towards capital cost have been recognised as operating lease rentals and in respect of variable cost that includes fuel costs, operations and maintenance, etc. is considered as revenue from sale of products/services. Significant judgement is required in segregating the capacity charges due from the State grid between fixed and contingent payments. The Group has determined that since the capacity charges under the PPA are based on the number of units of electricity made available, which would be subject to variation on account of various factors like availability of coal and water for the plant, there are no fixed minimum payments under the PPA, which requires it to be accounted for on a straight line basis. The contingent rents recognised are disclosed in Note 6.
In the normal course of business, contingent liabilities may arise from litigation, taxation and other claims against the Group. A provision is recognised when the Group has a present obligation as a result of past events, and it is probable that the Group will be required to settle that obligation. 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 consolidated financial statements. When considering the classification of legal or tax cases as probable, possible or remote, there is judgement involved. This pertains to the application of the legislation, which in certain cases is based upon management’s interpretation of country specific applicable law, in particular India, and the likelihood of settlement. Management uses in-house and external legal professionals to make informed decision. Although there can be no assurance regarding the final outcome of the legal proceedings, the Group does not expect them to have a materially adverse impact on the Group’s financial position, profitability or cash flows. These are set out in Note 33.
In certain cases, the Group’s power customers are disputing various contractual provisions of PPA’s. Significant judgement is required in both assessing the tariff to be charged under the PPA in accordance with IFRS 15 and to assess the recoverability of withheld revenue currently accounted for as receivables. In assessing this critical judgment management, considered favourable external legal opinions the Group has obtained in relation to the claims and favourable court judgements in the related matter. In addition, the fact that the contracts are with government owned companies implies the credit risk is low. Refer Note 17. |

| Summary of Provisions |
(a) 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 from a producing field. The provisions for restoration, rehabilitation and environmental liabilities represent the management’s best estimate of the costs which will be incurred in the future to meet the Group’s obligations under existing Indian, Australian, Namibian, South African and Irish law and the terms of the Group’s exploration and other licences and contractual arrangements. Within India, the principal restoration and rehabilitation provisions are recorded within Oil and Gas division where a legal obligation exists relating to the oil and gas fields and where costs are expected to be incurred in restoring the site of production facilities at the end of the producing life of an oil field. The Group recognises the full cost of site restoration as a liability when the obligation to rectify environmental damage arises. These amounts are calculated by considering discount rates within the range of 2% to 10% and become payable on closure of mines and are expected to be incurred over a period of to thirty years. The lower range of discount rate is at Oil and Gas and Zinc international operations in Ireland and higher range is at Zinc International operations in African c ountries. (b) Other provisions Other provisions include provision for disputed cases and claims. |
