1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES In this Form 10-K, references herein to "Novelis," the "Company," "we," "our," or "us" refer to Novelis Inc. and its subsidiaries unless the context specifically indicates otherwise. References herein to "Hindalco" refer to Hindalco Industries Limited. Hindalco acquired Novelis in May 2007. Effective September 1, 2022, Novelis Inc. and AV Metals, Inc. (which, prior to such date, was our sole shareholder and a wholly owned subsidiary of AV Minerals (Netherlands) N.V.) completed a plan of arrangement, pursuant to which AV Metals, Inc. merged with and into Novelis Inc., with Novelis Inc. surviving the merger. As of the effectiveness of the plan of arrangement, all of the outstanding shares of Novelis are owned directly by AV Minerals (Netherlands) N.V. and indirectly by Hindalco. Prior to the effectiveness of the plan of arrangement, AV Metals, Inc. was a holding company, with its assets being comprised solely of its investment in Novelis, and without any operations. The plan of arrangement was a combination of entities under common control and resulted in a change in the reporting entity. The opening balance of additional paid-in capital has been increased and that of retained earnings reduced by $4 million in the earliest period presented. Unless otherwise specified, the period referenced is the current fiscal year. All tonnages are stated in metric tonnes. One metric tonne is equivalent to 2,204.6 pounds. One kt is 1,000 metric tonnes. Organization and Description of Business We produce aluminum sheet and light gauge products for use in the packaging market, which includes beverage and food can and foil products, as well as for use in the automotive, transportation, aerospace, electronics, architectural, and industrial product markets. As of March 31, 2023, we had manufacturing operations in nine countries on four continents: North America, South America, Asia, and Europe, through 33 operating facilities, which may include any combination of hot or cold rolling, finishing, casting, or recycling capabilities. We have recycling operations in 15 of our operating facilities to recycle post-consumer aluminum, such as used-beverage cans, and post-industrial aluminum, such as class scrap. Consolidation Policy Our consolidated financial statements have been prepared in accordance with U.S. GAAP and include the assets, liabilities, revenues, and expenses of all wholly owned subsidiaries, majority-owned subsidiaries over which we exercise control, and entities in which we have a controlling financial interest or are deemed to be the primary beneficiary. We eliminate intercompany accounts and transactions from our consolidated financial statements. We use the equity method to account for our investments in entities that we do not control but have the ability to exercise significant influence over operating and financial policies. Consolidated net income attributable to our common shareholder includes our share of net income (loss) of these entities. The difference between consolidation and the equity method impacts certain of our financial ratios because of the presentation of the detailed line items reported in the consolidated financial statements for consolidated entities, compared to a two-line presentation of investment in and advances to non–consolidated affiliates and equity in net income of non-consolidated affiliates. Use of Estimates and Assumptions The preparation of our consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting periods. The principal areas of judgment relate to (1) impairment of goodwill; (2) actuarial assumptions related to pension and other postretirement benefit plans; (3) tax uncertainties and valuation allowances; and (4) assessment of loss contingencies, including environmental and litigation liabilities. Future events and their effects cannot be predicted with certainty, and accordingly, our accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of our consolidated financial statements may change as new events occur, more experience is acquired, additional information is obtained, and our operating environment changes. We evaluate and update our assumptions and estimates on an ongoing basis and may employ outside experts to assist in our evaluations. Actual results could differ from the estimates we have used. For more information regarding our use of estimates in the determination of fair values of assets acquired and liabilities assumed in the acquisition of Aleris, see Note 2 – Business Combination . Risks and Uncertainties We are exposed to a number of risks in the normal course of our business that could potentially affect our financial position, results of operations, and cash flows. Risks & Uncertainties resulting from Inflation, COVID-19, and Geopolitical Instability Fiscal 2023 was marked by global economic uncertainty, capital markets disruption, and supply chain interruptions, which have been impacted by inflationary cost pressures, ongoing recovery from the COVID-19 pandemic, and geopolitical instability due to the military conflict between Russia and Ukraine. We have experienced increased inflationary cost pressures in fiscal 2023 resulting from global supply chain disruptions impacting the availability and price of materials and services including energy, freight, coatings, and alloys, such as magnesium. Geopolitical instability exacerbated inflationary cost pressures, which are expected to continue for the foreseeable future. We have not experienced significant direct impacts from the Russia-Ukraine conflict, as we do not have operations nor significant sales in either Russia or Ukraine. However, we have experienced indirect impacts, as the conflict has driven up energy prices globally, beginning in the fourth quarter of fiscal 2022, and we expect these costs will remain elevated until energy prices stabilize. To date, our operations have not been materially impacted by labor shortages, and we remain able to procure the necessary raw materials, parts, and equipment due to our diverse, global supplier network. While much of our customer demand and shipments have recovered in the majority of our end markets from the impact of the COVID-19 pandemic, we cannot predict the overall extent of the impact of any resurgence of COVID-19, its variants or any future pandemic on our operating results, cash flows, liquidity, and financial condition, which will depend on certain developments, including the duration and spread of such outbreak and its impact on our customers, employees, suppliers, and other partners. We believe we are positioned to maintain production levels necessary to service our customers in the near term. However, we cannot predict how long energy and other operating input prices will remain inflated, supply chains will continue to experience disruptions, or potential future financial impacts. We have been able to mitigate a portion of the higher inflationary cost impact through a combination of hedging, passing through a portion of higher costs to customers, favorable pricing environments, and increased recycled inputs. There is no assurance that we will continue to be able to mitigate these higher costs in the future. The overall extent of the impact of these factors on our operating results, cash flows, liquidity, and financial condition will depend on certain developments, including the duration of the current inflationary environment, supply chain disruptions, end market demand, and the Russia-Ukraine conflict. Although we have made our best estimates based on the current information, the effects of these factors on our business may result in future changes to our estimates and assumptions based on their duration. Actual results could materially differ from the estimates and assumptions developed by management. If so, we may be subject to future impairment charges as well as changes to recorded reserves and valuations. Laws and regulations We operate in an industry that is subject to a broad range of environmental, health and safety laws and regulations in the jurisdictions in which we operate. These laws and regulations impose increasingly stringent environmental, health and safety protection standards and permitting requirements regarding, among other things, air emissions; wastewater discharges; the handling, storage, and disposal of hazardous substances and wastes; the remediation of contaminated sites and restoration of natural resources; carbon and other greenhouse gas emissions; and employee health and safety. Some environmental laws, such as the U.S. Comprehensive Environmental Response, Compensation, and Liability Act, also known as CERCLA or Superfund, and comparable state laws impose joint and several liability for the cost of environmental remediation, natural resource damages, third-party claims, and other expenses, without regard to the fault or the legality of the original conduct. The costs of complying with these laws and regulations, including participation in assessments and remediation of contaminated sites and installation of pollution control facilities, have been, and in the future could be, significant. In addition, these laws and regulations may also result in substantial environmental liabilities associated with divested assets, third-party locations, and past activities. In certain instances, these costs and liabilities, as well as related actions to be taken by us, could be accelerated or increased if we were to close, divest of, or change the principal use of certain facilities with respect to which we may have environmental liabilities or remediation obligations. Currently, we are involved in a number of compliance efforts, remediation activities, and legal proceedings concerning environmental matters, including certain activities and proceedings arising under U.S. Superfund and comparable laws in other jurisdictions where we have operations. We have established liabilities for environmental remediation where appropriate. However, the cost of addressing environmental matters (including the timing of any charges related thereto) cannot be predicted with certainty, and these liabilities may not ultimately be adequate, especially in light of potential changes in environmental conditions, changing interpretations of laws and regulations by regulators and courts, the discovery of previously unknown environmental conditions, the risk of governmental orders to carry out additional compliance on certain sites not initially included in remediation in progress, our potential liability to remediate sites for which provisions have not been previously established, and the adoption of more stringent environmental laws. Such future developments could result in increased environmental costs and liabilities and could require significant capital expenditures, any of which could have a material adverse effect on our financial position, results of operations, or cash flows. Furthermore, the failure to comply with our obligations under applicable environmental, health and safety laws and regulations could subject us to administrative, civil, or criminal penalties, obligations to pay damages or other costs, and injunctions or other orders, including orders to cease operations. In addition, the presence of environmental contamination at our properties could adversely affect our ability to sell a property, receive full value for a property, or use a property as collateral for a loan. Some of our current and potential operations are located or could be located in or near communities that may regard such operations as having a detrimental effect on their social and economic circumstances. Environmental laws typically provide for participation in permitting decisions, site remediation decisions and other matters. Concern about environmental justice issues may affect our operations. Should such community objections be presented to government officials, the consequences of such a development may have a material adverse impact upon the profitability or, in extreme cases, the viability of an operation. In addition, such developments may adversely affect our ability to expand or enter into new operations in such location or elsewhere and may also have an effect on the cost of our environmental remediation projects. We use a variety of hazardous materials and chemicals in our rolling processes and in connection with maintenance work on our manufacturing facilities. Because of the nature of these substances or related residues, we may be liable for certain costs, including, among others, costs for health-related claims or removal or re-treatment of such substances. Certain of our current and former facilities incorporated asbestos-containing materials, a hazardous substance that has been the subject of health-related claims for occupation exposure. In addition, although we have developed environmental, health and safety programs for our employees, including measures to reduce employee exposure to hazardous substances, and conduct regular assessments at our facilities, we are currently, and in the future may be, involved in claims and litigation filed on behalf of persons alleging injury predominantly as a result of occupational exposure to substances at our current or former facilities. It is not possible to predict the ultimate outcome of these claims and lawsuits due to the unpredictable nature of personal injury litigation. If these claims and lawsuits, individually or in the aggregate, were finally resolved against us, our financial position, results of operations, and cash flows could be adversely affected. Materials and labor In the aluminum rolled products industry, our raw materials are subject to continuous price volatility. We may not be able to pass on the entire cost of the increases to our customers or offset fully the effects of higher raw material costs through productivity improvements, which may cause our profitability to decline. In addition, there is a potential time lag between changes in prices under our purchase contracts and the point when we can implement a corresponding change under our sales contracts with our customers. As a result, we could be exposed to fluctuations in raw materials prices which could have a material adverse effect on our financial position, results of operations, and cash flows. Significant price increases may result in our customers substituting other materials, such as plastic or glass, for aluminum or switching to another aluminum rolled products producer, which could have a material adverse effect on our financial position, results of operations, and cash flows. We consume substantial amounts of energy in our rolling operations and our cast house operations. The factors that affect our energy costs and supply reliability tend to be specific to each of our facilities. A number of factors could materially adversely affect our energy position including, but not limited to increases in the cost of natural gas; increases in the cost of supplied electricity or fuel oil related to transportation; interruptions in energy supply due to equipment failure or other causes; and the inability to extend energy supply contracts upon expiration on favorable terms. A significant increase in energy costs or disruption of energy supplies or supply arrangements could have a material adverse effect on our financial position, results of operations, and cash flows. A substantial portion of our employees are represented by labor unions under a large number of collective bargaining agreements with varying durations and expiration dates. Although we have not experienced a material impact to our operations from a strike or work stoppage in recent years, we may not be successful in preventing such an event from occurring in the future at one or more of our manufacturing facilities. In addition, we may not be able to satisfactorily renegotiate our collective bargaining agreements when they expire. Any work stoppages or material changes in the terms of our labor agreements could have an adverse impact on our financial condition. Geographic markets We are, and will continue to be, subject to financial, political, economic, and business risks in connection with our global operations. We have made investments and carry on production activities in various emerging markets, including China, Brazil, and South Korea, and we market our products in these countries, as well as certain other countries in Asia, Africa, and the Middle East. While we anticipate higher growth or attractive production opportunities from these emerging markets, they also present a higher degree of risk than more developed markets. In addition to the business risks inherent in developing and servicing new markets, economic conditions may be more volatile, legal and regulatory systems may be less developed and predictable, and the possibility of various types of adverse governmental action may be more pronounced. In addition, inflation, fluctuations in currency and interest rates, competitive factors, civil unrest, and labor problems could affect our revenues, expenses, and results of operations. Our operations could also be adversely affected by acts of war (including the Russia-Ukraine conflict), terrorism, or the threat of any of these events as well as government actions such as controls on imports, exports and prices, tariffs, new forms of taxation, changes in fiscal regimes, and increased government regulation in the countries in which we operate or service customers. Unexpected or uncontrollable events or circumstances in any of these markets could have a material adverse effect on our financial position, results of operations, and cash flows. Other risks and uncertainties In addition, refer to Note 17 – Financial Instruments and Commodity Contracts , Note 19 – Fair Value Measurements , and Note 22 – Commitments and Contingencies for a discussion of financial instruments and commitments and contingencies. Net Sales We recognize revenue in accordance with ASC 606, Revenue from Contracts with Customers. The Company's contracts with customers consist of purchase orders with standard terms and conditions. These contracts typically consist of the manufacture of products, which represent single performance obligations that are satisfied upon transfer of control of the product to the customer at a point in time. Transfer of control is assessed based on alternative use of the products we produce and our enforceable right to payment for performance to date under the contract terms. Transfer of control and revenue recognition generally occur upon shipment or delivery of the product, which is when title, ownership, and risk of loss pass to the customer and is based on the applicable shipping terms. The shipping terms vary across all businesses and depend on the product, the country of origin, and the type of transportation (truck, train, or vessel). The length of payment terms can vary per contract, but none extend beyond one year. Revenue is recognized net of any volume rebates or other incentives. Occasionally we receive advance payments to secure product to be delivered in future periods. These advance payments are recorded as deferred revenue, and revenue is recognized as our performance obligations are satisfied throughout the term of the applicable contract. Certain of our contracts contain take-or-pay clauses which allow us to recover an agreed upon penalty if a buyer does not purchase contractual minimums as defined in the underlying contract within a set timeframe, which is generally within one year. Additionally, certain of our contracts may contain incentive payments to our customers that are deferred and amortized as a reduction to the amount of revenue recorded on a straight-line basis over the term of these contracts. During fiscal 2023 and fiscal 2021, we recognized $37 million and $38 million, respectively, in net sales associated with these customer contractual obligations. During fiscal 2022, amounts recognized in net sales associated with these customer contractual obligations were not material. We disaggregate revenue from contracts with customers on a geographic basis. This disaggregation also achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of net sales and cash flows are affected by economic factors. We manage our activities on the basis of geographical regions and are organized under four operating segments: North America, South America, Asia, and Europe. See Note 23 – Segment, Geographical Area, Major Customer and Major Supplier Information for further information about our segment revenue. Cost of Goods Sold (Exclusive of Depreciation and Amortization) Cost of goods sold (exclusive of depreciation and amortization) includes all costs associated with inventories, including the procurement of materials, the costs to convert such materials into finished products, and the costs of warehousing and distributing finished goods to customers. Material procurement costs include inbound freight charges as well as purchasing, receiving, inspection, and storage costs. Conversion costs include the costs of direct production inputs such as labor and energy, as well as allocated overheads from indirect production centers and plant administrative support areas. Warehousing and distribution costs include inside and outside storage costs, outbound freight charges, and the costs of internal transfers. Selling, General and Administrative Expenses Selling, general and administrative expenses include selling, marketing, and advertising expenses; salaries, travel, and office expenses of administrative employees and contractors; legal and professional fees; software license fees; the provision for credit losses; and factoring expenses. Research and Development Expenses We incur costs in connection with R&D programs that are expected to contribute to future earnings and charge such costs against income as incurred. Research and development expenses consist primarily of salaries and administrative costs. Restructuring Activities Restructuring charges, which are recorded within restructuring and impairment, net on our consolidated statements of operations, include employee severance and benefit costs, impairments of certain assets, and other costs associated with exit activities. Restructuring costs are determined based on estimates, which are prepared at the time the restructuring actions were approved by management and are periodically reviewed and updated for changes in estimates. We apply the provisions of ASC 420, Exit or Disposal Cost Obligations ("ASC 420") and ASC 712, Compensation — Nonretirement Postemployment Benefits ("ASC 712" ). Severance and benefit costs related to restructuring activities are accounted for under ASC 420 and/or ASC 712 and are recognized when management with the proper level of authority has committed to a restructuring plan and communicated those actions to employees. Impairment losses are based upon the estimated fair value less costs to sell, with fair value estimated based on existing market prices for similar assets. Other exit costs include environmental remediation costs and contract termination costs, primarily related to equipment and facility lease obligations. At each reporting date, we evaluate the accruals for restructuring costs to ensure the accruals are still appropriate. See Note 4 – Restructuring and Impairment for further discussion. Business Acquisition and Other Related Costs Business acquisition and other related costs includes costs associated with the acquisition of Aleris, including legal and professional fees associated with the transaction. See Note 2 – Business Combination for further details about the transaction. Cash and Cash Equivalents Cash and cash equivalents includes investments that are highly liquid and have maturities of three months or less when purchased. The carrying values of cash and cash equivalents approximate their fair value due to the short-term nature of these instruments. We maintain amounts on deposit with various financial institutions, which may at times exceed federally insured limits. However, management periodically evaluates the creditworthiness of those institutions, and we have not experienced any losses on such deposits. Restricted Cash Restricted cash primarily relates to cash deposits for employee benefits and is disclosed on the consolidated statement of cash flows. Restricted cash is included in prepaid expenses and other current assets and other long–term assets on the consolidated balance sheets. Accounts Receivable, Net Our accounts receivable are geographically dispersed. We do not obtain collateral relating to our accounts receivable. We do not believe there are any significant concentrations of revenues from any particular customer or group of customers that would subject us to any significant credit risks in the collection of our accounts receivable. We report accounts receivable at the estimated net realizable amount we expect to collect from our customers. Additions to the allowance for credit losses are made by means of the provision for credit losses. We write-off uncollectible accounts receivable against the allowance for credit losses after exhausting collection efforts. For each of the periods presented, we performed an analysis of our historical cash collection patterns and considered the impact of any known material events in determining the allowance for credit losses. See Note 5 – Accounts Receivable for further information. Inventories We carry our inventories at the lower of their cost or net realizable value, reduced by obsolete and excess inventory. We use the average cost method to determine cost. Included in inventories are stores inventories, which are carried at average cost. See Note 6 – Inventories for further discussion. Derivative Instruments We hold derivatives for risk management purposes rather than for trading. We use derivatives to mitigate uncertainty and volatility caused by underlying exposures to metal prices, foreign exchange rates, and energy prices. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date and are reported gross. We may be exposed to losses in the future if counterparties to our derivative contracts fail to perform. We are satisfied that the risk of such non-performance is remote due to our monitoring of credit exposures. Additionally, we enter into master netting agreements with contractual provisions that allow for netting of counterparty positions in case of default, and we do not face credit contingent provisions that would result in the posting of collateral. In accordance with ASC 815, Derivatives and Hedging, for cash flow hedges we recognize and defer the entire periodic change in the fair value of the hedging instrument in other comprehensive income (loss). The amounts recorded in other comprehensive income (loss) are subsequently reclassified to earnings in the same line item impacted by the hedged item when the hedged item affects earnings. For derivatives designated as cash flow hedges or net investment hedges, we assess hedge effectiveness by formally evaluating the high correlation of the expected future cash flows of the hedged item and the derivative hedging instrument. The entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is included in other comprehensive income (loss) and reclassified to earnings in the period in which earnings are impacted by the hedged items or in the period that the transaction becomes probable of not occurring. Gains or losses representing reclassifications of other comprehensive income (loss) to earnings are recognized in the same line item that is impacted by the underlying exposure. We exclude the time value component of foreign currency and aluminum price risk hedges when measuring and assessing effectiveness to align our accounting policy with risk management objectives when it is necessary. If at any time during the life of a cash flow hedge relationship we determine that the relationship is no longer effective, the derivative will no longer be designated as a cash flow hedge and future gains or losses on the derivative will be recognized in other expenses (income), net. For derivatives designated as fair value hedges, we assess hedge effectiveness by formally evaluating the high correlation of changes in the fair value of the hedged item and the derivative hedging instrument. The changes in the fair values of the underlying hedged items are reported in prepaid expenses and other current assets, other long–term assets, accrued expenses and other current liabilities, and other long–term liabilities in the consolidated balance sheets. Changes in the fair values of these derivatives and underlying hedged items generally offset, and the entire change in the fair value of derivatives is recorded in the consolidated statement of operations line item consistent with the underlying hedged item. If no hedging relationship is designated, gains or losses are recognized in other expenses (income), net in our consolidated statements of operations. Consistent with the cash flows from the underlying risk exposure, we classify cash settlement amounts associated with designated derivatives as part of either operating or investing activities in the consolidated statements of cash flows. If no hedging relationship is designated, we classify cash settlement amounts as part of investing activities in the consolidated statement of cash flows. The majority of our derivative contracts are valued using industry-standard models that use observable market inputs as their basis, such as time value, forward interest rates, volatility factors, and current ("spot") and forward market prices for commodity and foreign exchange rates. See Note 17 – Financial Instruments and Commodity Contracts and Note 19 – Fair Value Measurements for additional discussion related to derivative instruments. Property, Plant and Equipment We record land, buildings, leasehold improvements, and machinery and equipment at cost. We record assets under finance lease obligations at the lower of their fair value or the present value of the aggregate future minimum lease payments as of the beginning of the lease term. We generally depreciate our assets using the straight-line method over the shorter of the estimated useful life of the assets or the lease term, excluding any lease renewals, unless the lease renewals are reasonably certain. See Note 7 – Property, Plant and Equipment for further discussion. We assign useful lives to and depreciate major components of our property, plant and equipment. The ranges of estimated useful lives follow. Range in Years Buildings 30 to 40 Leasehold improvements 7 to 20 Machinery and equipment 2 to 25 Furniture, fixtures and equipment 3 to 10 Equipment under finance lease obligations 5 to 15 Most of our large scale machinery, including hot mills, cold mills, continuous casting mills, furnaces, and finishing mills have useful lives of 15 to 25 years. Supporting machinery and equipment, including automation and work rolls, have useful lives of 2 to 15 years. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life of an asset. We also capitalize construction costs and interest incurred while major construction and development projects are in progress. These amounts are capitalized as construction in progress within property, plant and equipment until the asset is placed into service. Once placed into service, the asset, including the associated capitalized interest, is reclassified from construction in progress to the appropriate property, plant and equipment component and depreciation commences. We retain fully depreciated assets in property and accumulated depreciation accounts until they are removed from service. In the case of sale, retirement, or disposal, the asset cost and related accumulated depreciation balances are removed from the respective accounts, and the resulting net amount, after consideration of any proceeds, is included as a gain or loss in othe |

2. BUSINESS COMBINATION | 2. BUSINESS COMBINATION On April 14, 2020, Novelis completed its acquisition of 100% of the issued and outstanding shares of Aleris, a global supplier of rolled aluminum products, pursuant to an Agreement and Plan of Merger, dated as of July 26, 2018 (the "Merger Agreement"). The closing purchase price of $2.8 billion consisted of $775 million less transaction costs for the equity value, as well as approximately $2.0 billion for the extinguishment of Aleris' current outstanding debt and a $50 million earn-out payment. The $775 million base equity payment was reduced by $64 million of Aleris transaction costs, resulting in $711 million of cash for equity consideration. As a result, the acquisition increases the Company's footprint as an aluminum rolled products manufacturer by expanding the portfolio of services provided to its customers. Refer to Note 3 – Discontinued Operations for more details on the Duffel and Lewisport divestitures required as a condition of the acquisition. As a condition to the sale of the Duffel plant, we were required by the European Commission to make a payment of €55 million (approximately $60 million at the date of acquisition) to support capital improvements at the Duffel plant upon sale. The final calculation of merger consideration paid to Aleris follows. in millions Amount Cash for equity consideration (1) $ 711 Repayment of Aleris' debt (including prepayment penalties and accrued interest) (2) 1,954 Earn-out consideration (3) 50 Payment associated with Duffel capital expenditures (4) 60 Fair value of merger consideration $ 2,775 _________________________ (1) Under the terms of the Merger Agreement, this represents the cash consideration, which is the base consideration for the settlement of all shares of common stock outstanding, including shares issued in connection with the conversion of the 6% Senior Subordinated Exchangeable Notes due 2020 issued by Aleris International, Inc. into Aleris common shares, and the settlement of stock options and restricted stock units, less transaction costs of $64 million. The transaction costs are removed from the base consideration as these costs were incurred by Aleris prior to the closing date and were not reimbursed by Novelis. Additionally, under the terms of the Merger Agreement, there is a €8 million (approximately $9 million at the date of acquisition) German tax indemnification included in the cash for equity consideration that will be payable to the selling shareholders upon the condition that the existing Aleris German tax receivable is received from the German tax authorities. During the third quarter of fiscal 2021, Novelis settled this payable with the selling shareholders. (2) On the closing date, all of the outstanding historical debt of Aleris, except for certain non-recourse multi-currency secured term loan facilities (collectively, the "Zhenjiang Term Loans"), was repaid in connection with the merger. In addition, prepayment penalties and accrued interest of approximately $12 million and $16 million, respectively, associated with the Aleris debt were paid in connection with such repayment. (3) Under the terms of the Merger Agreement, this represents the fair value of the earn-out consideration which was based upon Aleris meeting specified commercial margin targets. On the closing date, Aleris had met all of the specified targets in the Merger Agreement and the selling shareholders received the $50 million cash payment. (4) In connection with obtaining the regulatory antitrust approvals, the European Commission required Novelis to pay the buyer of Duffel an additional €55 million (approximately $60 million at the date of acquisition) to fund capital expenditures that would be required so that Duffel can operate as a standalone business. This amount was paid on September 30, 2020 and is included in acquisition of business and other investments, net of cash and restricted cash acquired in the consolidated statement of cash flows for fiscal 2021. The acquisition was accounted for as a business combination using the acquisition method of accounting in accordance with ASC 805. The purchase price was allocated to the assets acquired and liabilities assumed based on the fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill, none of which is expected to be deductible for tax purposes. Goodwill is primarily attributed to synergies from future expected economic benefits, including enhanced revenue growth from expanded capabilities and geographic presence, as well as cost savings from duplicative overhead, streamlined operations, and enhanced operational efficiency. The accompanying consolidated balance sheets include the assets and liabilities of Aleris, which were measured at fair value as of the acquisition date. The discontinued operations financial statement line items in the table below relate to Duffel and Lewisport. The preliminary allocation of purchase price recorded for Aleris as of June 30, 2020 and subsequently revised for measurement period adjustments follows. in millions Assets Acquired as of June 30, 2020 (1) Measurement Period Adjustments Assets Acquired as of March 31, 2021 (1) Cash and cash equivalents $ 105 $ — $ 105 Accounts receivable (2) 251 17 268 Inventories 379 — 379 Prepaid expenses and other current assets (3) 24 — 24 Fair value of derivative instruments 46 — 46 Current assets of discontinued operations (4) 463 1 464 Property, plant and equipment (5) 949 (5) 944 Goodwill (6)(7)(8)(9) 328 141 469 Intangible assets, net (5)(6) 149 318 467 Deferred income tax assets (7) 114 (20) 94 Other long-term assets 39 — 39 Long–term assets of discontinued operations (8) 944 (390) 554 Total assets $ 3,791 $ 62 $ 3,853 Liabilities Assumed as of June 30, 2020 (1) Measurement Period Adjustments Liabilities Assumed as of March 31, 2021 (1) Current portion of long–term debt $ 24 $ — $ 24 Accounts Payable (2) 141 17 158 Fair value of derivative instruments 25 — 25 Accrued expenses and other current liabilities 143 — 143 Current liabilities of discontinued operations 166 — 166 Long–term debt, net of current portion 125 — 125 Deferred income tax liabilities (7) 37 4 41 Accrued postretirement benefits 164 — 164 Other long–term liabilities (9) 41 41 82 Long–term liabilities of discontinued operations 150 — 150 Total liabilities $ 1,016 $ 62 $ 1,078 Net assets acquired $ 2,775 Total purchase price $ 2,775 _________________________ (1) In connection with the acquisition of Aleris, the Company acquired two businesses which were required to be sold. Therefore, such businesses were classified as held for sale and were included within the current assets of discontinued operations, long-term assets of discontinued operations, current liabilities of discontinued operations, and long–term liabilities of discontinued operations line items in the above allocation of purchase price (see Note 3 – Discontinued Operations ). As of March 31, 2021, both of these businesses were sold and are no longer included in the consolidated balance sheets of Novelis. (2) The measurement period adjustment related to the presentational alignment of pending derivative settlements on a gross basis in accordance with Novelis' policy during the second quarter of fiscal 2021. (3) Included in prepaid expenses and other current assets is $9 million of restricted cash acquired related to cash deposits restricted for the payment of the Zhenjiang Term Loans. (4) Included in current assets of discontinued operations is $41 million of cash and cash equivalents acquired related to our discontinued operations. (5) The measurement period adjustment of $5 million related to presentational alignment of certain capitalized software in accordance with Novelis' policy during the third quarter of fiscal 2021. (6) The measurement period adjustment related to revisions in the valuation of intangible assets based on refinements to key assumptions, such as discount rates and growth rates, of $261 million and $52 million during the second and third quarters of fiscal 2021, respectively. (7) The measurement period adjustment related to deferred tax impacts of the measurement period adjustments and other tax adjustments, resulting in a decrease in deferred tax assets of $34 million during the second quarter, an increase of $22 million during the third quarter, and a decrease of $8 million during the fourth quarter of fiscal 2021, respectively. Deferred tax liabilities were adjusted by $4 million in the fourth quarter of fiscal 2021. (8) The measurement period adjustment related to estimated costs to sell the Duffel and Lewisport businesses, in addition to revisions to key assumptions of the valuation of Lewisport and Duffel's property, plant and equipment, of $284 million and $75 million during the second and third quarters of fiscal 2021, respectively, and revisions to key assumptions related to Lewisport's intangible assets of $31 million during the second quarter of fiscal 2021. (9) The measurement period adjustment related to certain uncertain tax positions and customs related adjustments identified during the third quarter of fiscal 2021. The fair values of assets acquired and liabilities are final as of March 31, 2021. The fair values of the assets acquired and liabilities assumed of discontinued operations were determined using estimated sales prices. The fair values of the continuing operations assets acquired and liabilities assumed were determined using the income and cost approaches. In many cases, the determination of the fair values required estimates about discount rates, future expected cash flows, and other future events that were judgmental and subject to change. The fair value measurements are primarily based on significant inputs that are not observable in the market and thus represent Level 3 measurements in the fair value hierarchy as defined in ASC 820. Intangible assets consisting of customer relationships, technology, and trade names were valued using the multi-period excess earnings method or the relief from royalty method, both of which are forms of the income approach. A cost and market approach was applied, as appropriate, for inventory and property and equipment, including land. Customer relationship intangible assets were valued using the multi-period excess earnings method. The significant assumptions used include the estimated annual net cash flows (including appropriate revenue and profit attributable to the asset, retention rate, applicable tax rate, and contributory asset charges, among other factors), the discount rate, reflecting the risks inherent in the future cash flow stream, an assessment of the asset's life cycle, and the tax amortization benefit, among other factors. Technology and trade name intangible assets were valued using the relief from royalty method. The significant assumptions used include the estimated annual net cash flows (including appropriate revenue attributable to the asset, applicable tax rate, royalty rate, and other factors such as technology related obsolescence rates), the discount rate, reflecting the risks inherent in the future cash flow stream, and the tax amortization benefit, among other factors. Inventory was valued using the replacement cost or market approach, as appropriate. The replacement cost approach, which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility, was used to determine the estimated replacement cost of raw materials. The market approach was used to determine the estimated selling price less costs to sale for work in progress and finished goods. Property and equipment, including land, were valued using the cost or market approach, as appropriate. For assets valued using the cost approach, the cost to replace a given asset reflects the estimated reproduction or replacement cost for the property, less an allowance for loss in value due to depreciation. The market approach, which estimates value by leveraging comparable land sale data/listings and qualitatively comparing them to the in-scope properties, was used to value the land. The assumed long-term debt in China was valued using an income approach. The significant assumptions used include the estimated annual cash flows and interest and credit spreads, among other factors. The assumed pension and postretirement liabilities were valued using an income approach. The significant assumptions used include the estimated annual cash flows, the discount rate, and the estimated return on asset rate, among other factors. The fair value of the assets acquired includes current accounts receivables of $268 million related to continuing operations and $78 million related to discontinued operations. The gross amount due is $346 million, of which less than $1 million is expected to be uncollectible. The fair value of the assets acquired includes $22 million and $7 million of operating lease right-of-use assets and finance lease assets, respectively. The fair value of liabilities assumed includes $9 million and $7 million of operating lease liabilities and finance lease liabilities, respectively, of which, $4 million and $3 million of operating lease liabilities and finance lease liabilities, respectively, are current liabilities. The Company has allocated the goodwill associated with the Aleris acquisition to the regions in the amounts below. in millions North America Europe Asia Total Goodwill $ 375 $ 53 $ 41 $ 469 The amounts allocated to intangible assets are as follows. in millions Gross Carrying Amount (1) Weighted-Average Useful Life Trade name $ 10 2.5 years Technology 52 15.1 years Customer relationships 403 22.5 years Other intangibles 2 N/A Total $ 467 21.2 years _________________________ (1) In connection with the acquisition of Aleris, Novelis acquired two businesses which we were obligated to sell. As such, gross carrying amounts exclude amounts held for sale (see Note 3 – Discontinued Operations ). Between the acquisition date and March 31, 2021, the results of continuing operations for Aleris of $1.6 billion of net sales and $144 million of net loss have been included within the accompanying consolidated statement of operations for fiscal 2021. The following unaudited supplemental pro forma combined financial information presents the Company's results of operations for fiscal 2021 and fiscal 2020 as if the acquisition of Aleris had occurred on April 1, 2019. The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the Company's operating results that may have actually occurred had the acquisition of Aleris been completed on April 1, 2019. In addition, the unaudited pro forma financial information does not give effect to any anticipated cost savings, operating efficiencies, or other synergies that may be associated with the acquisition or any estimated costs that have been or will be incurred by the Company to integrate the assets and operations of Aleris. in millions Fiscal 2021 Fiscal 2020 Net sales $ 12,330 $ 13,175 Net income 306 412 The unaudited pro forma financial information reflects pro forma adjustments to present the combined pro forma results of operations as if the acquisition had occurred on April 1, 2019 to give effect to certain events the Company believes to be directly attributable to the acquisition. These pro forma adjustments primarily include: • the elimination of Aleris historical depreciation and amortization expense and the recognition of new depreciation and amortization expense; • an adjustment to interest expense to reflect the additional borrowings of the Company in conjunction with the acquisition and the repayment of Aleris' historical debt in conjunction with the acquisition; • an adjustment to present acquisition-related transaction costs and other one-time costs directly attributable to the acquisition as if they were incurred in the earliest period presented; and • the related income tax effects of the adjustments noted above. |

DISCONTINUED OPERATIONS | 3. DISCONTINUED OPERATIONS On April 14, 2020, we closed the acquisition of Aleris for $2.8 billion. As a result of the antitrust review processes in the European Union, the U.S., and China required for approval of the acquisition, we were obligated to divest Aleris' European and North American automotive assets, including the Duffel and Lewisport plants. See Note 2 – Business Combination for more details on the acquisition and related accounting treatment. Duffel On September 30, 2020, we completed the sale of Duffel to Liberty House Group through its subsidiary, ALVANCE, the international aluminum business of the GFG Alliance. Upon closing, we received €210 million ($246 million as of September 30, 2020) in cash and a €100 million ($117 million as of September 30, 2020) receivable that was deemed to be contingent consideration subject to the results of a binding arbitration proceeding under German law. We accounted for this contingent consideration at fair value and marked to fair value on a quarterly basis. As of June 30, 2021, Novelis marked all outstanding receivables related to the sale of Duffel to an estimated fair value of €45 million ($53 million), which resulted in a loss of €51 million ($61 million) recorded in loss from discontinued operations, net of tax. In June 2022, Duffel was acquired by American Industrial Partners Capital Fund VII, L.P. (together with its affiliates, "AIP"). In December 2022, the Company reached a settlement with AIP in order to reach a resolution to the dispute being arbitrated, among other matters. As part of the settlement, the contingent consideration balance was settled for €45 million ($46 million), consisting of €5 million ($5 million) in cash paid on the settlement date and a note in the amount of €40 million ($41 million). The note bears interest at the annual rate of 5% and matures on December 31, 2027, with interest and €0.2 million of principal payable semi-annually and the remainder of the principal payable at maturity. As a result of the settlement, the arbitration was dismissed in January 2023. The settlement did not have a material impact on the Company's consolidated statement of operations. The resolution reached with AIP also included the settlement of certain assets and liabilities that were previously classified as current assets and current liabilities of discontinued operations on our consolidated balance sheets. The settlement of such assets and liabilities did not have a material impact on the Company's consolidated statement of operations. Lewisport On November 8, 2020, we entered into a definitive agreement with American Industrial Partners for the sale of Lewisport and closed the sale on November 30, 2020. Upon closing, we received $180 million in cash proceeds. In addition, we received $19 million for net working capital adjustments during the third quarter of fiscal 2022. For fiscal 2021, the results of operations of Lewisport were presented within loss from discontinued operations, net of tax in the consolidated statement of operations and cash flows of Lewisport were presented as discontinued operations in the consolidated statements of cash flows. Loss on Sale of Discontinued Operations As a result of the transactions above, for fiscal 2021 we recorded a loss on sale of discontinued operations of $170 million, net of taxes, associated with the sales of Duffel and Lewisport. Cash flows from the sales of Duffel and Lewisport are included in the consolidated statements of cash flows for fiscal 2021 as net cash provided by investing activities - discontinued operations. An offsetting $46 million in net cash provided by investing activities - discontinued operations for fiscal 2021 relates primarily to capital expenditures and outflows from the sale of derivative instruments for Duffel and Lewisport during the period prior to their divestiture. |

Consolidation [Abstract] | |
9. CONSOLIDATION | 9. CONSOLIDATION Variable Interest Entity The entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and consolidates the VIE. An entity is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Logan is a consolidated joint venture in which we hold 40% ownership. Our joint venture partner is Tri-Arrows. Logan processes metal received from Novelis and Tri-Arrows and charges the respective partner a fee to cover expenses. Logan is a thinly capitalized VIE that relies on the regular reimbursement of costs and expenses from Novelis and Tri-Arrows to fund its operations. Novelis is considered the primary beneficiary and consolidates Logan since it has the power to direct activities that most significantly impact Logan's economic performance, an obligation to absorb expected losses, and the right to receive benefits that could potentially be significant to the VIE. Other than the contractually required reimbursements, we do not provide additional material support to Logan. Logan's creditors do not have recourse to our general credit. There are significant other assets used in the operations of Logan that are not part of the joint venture, as they are directly owned and consolidated by Novelis or Tri-Arrows. The following table summarizes the carrying value and classification of assets and liabilities owned by the Logan joint venture and consolidated in our consolidated balance sheets.

INVESTMENT IN AND ADVANCES TO NON-CONSOLIDATED AFFILIATES AND RELATED PARTY TRANSACTIONS Included in the accompanying consolidated financial statements are transactions and balances arising from business we conducted with our equity method non-consolidated affiliates. Alunorf Alunorf is a joint venture investment between Novelis Deutschland GmbH, a subsidiary of Novelis, and Speira GmbH. Each of the parties to the joint venture holds a 50% interest in the equity, profits and losses, shareholder voting, management control, and rights to use the production capacity of the facility. Alunorf tolls aluminum and charges the respective partner a fee to cover the associated expenses. UAL UAL is a joint venture investment between Novelis Korea Ltd., a subsidiary of Novelis, and Kobe. UAL is a thinly capitalized VIE that relies on the regular reimbursement of costs and expenses from Novelis and Kobe. UAL is controlled by an equally represented Board of Directors in which neither entity has sole decision-making ability regarding production operations or other significant decisions. Furthermore, neither entity has the ability to take the majority share of production or associated costs over the life of the joint venture. Our risk of loss is limited to the carrying value of our investment in and inventory-related receivables from UAL. UAL's creditors do not have recourse to our general credit. Therefore, UAL is accounted for as an equity method investment, and Novelis is not considered the primary beneficiary. UAL currently produces flat-rolled aluminum products exclusively for Novelis and Kobe. As of March 31, 2023, Novelis and Kobe both hold 50% interests in UAL. During fiscal 2023, we made additional contributions to UAL in the amount of $23 million. No such contributions were made during fiscal 2022. AluInfra AluInfra is a joint venture investment between Novelis Switzerland SA, a subsidiary of Novelis, and Constellium SE. Each of the parties to the joint venture holds a 50% interest in the equity, profits and losses, shareholder voting, management control, and rights to use the facility.

The difference is primarily related to the unamortized fair value adjustments that are included in our investment balance as a result of the acquisition of Novelis by Hindalco in 2007. As of March 31, 2023, the investment in UAL exceeded our proportionate share of the net assets by $46 million. The difference primarily relates to goodwill. The following table summarizes the results of operations of our equity method non-consolidated affiliates in the aggregate for fiscal 2023, fiscal 2022, and fiscal 2021 as well as the nature and amounts of significant transactions that we had with our non-consolidated affiliates.

Leases [Abstract] | |
11. LEASES | 11. LEASES We lease certain land, buildings, and equipment under non-cancelable operating lease arrangements and certain equipment and office space under finance lease arrangements. We used the following policies and/or assumptions in evaluating our lease population. • Lease determination: Novelis considers a contract to be or to contain a lease if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. • Discount rate: When our lease contracts do not provide a readily determinable implicit rate, we use the estimated incremental borrowing rate based on information available at the inception of the lease. The discount rate is determined by region and asset class. • Variable payments: Novelis includes payments that are based on an index or rate within the calculation of right-of-use leased assets and lease liabilities, which is initially measured at the lease commencement date. Other variable lease payments include, but are not limited to, maintenance, service, and supply costs. These costs are disclosed as a component of total lease costs. • Purchase options: Certain leases include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. • Renewal options: Most leases include one or more options to renew with renewal terms that can extend the lease term from one or more years. The exercise of lease renewal options is at our sole discretion. • Residual value guarantees, restrictions, or covenants: Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. • Short-term leases: Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term and expense the associated operating lease costs to selling, general and administrative expenses on the consolidated statements of operations. • Non-lease components: Leases that contain non-lease components (primarily equipment maintenance) are accounted for as a single component and recorded on the consolidated balance sheets for certain asset classes including real estate and certain equipment. Non-lease components include, but are not limited to, common area maintenance, service arrangements, and supply agreements.

We present stated rates of interest because they reflect the rate at which cash will be paid for future debt service. (2) Amounts include unamortized debt issuance costs, fair value adjustments, and debt discounts. (3) See Note 11 – Leases for more information. Principal repayment requirements for our total debt over the next five years and thereafter using exchange rates as of March 31, 2023 for our debt denominated in foreign currencies are as follows (in millions). As of March 31, 2023 Amount Short-term borrowings and current portion of long-term debt due within one year $ 759 2 years 766 3 years 22 4 years 776 5 years 482 Thereafter 2,895 Total debt $ 5,700 Short-Term Borrowings As of March 31, 2023, our short-term borrowings totaled $671 million, which consisted of $463 million of borrowings on our ABL Revolver, $107 million in short-term China loans (CNY 740 million), $100 million in Brazil loans, and $1 million in other short-term borrowings. In January 2022, we entered into a $315 million short-term loan with Axis Bank Limited, IFSC Banking Unit, Gift City, as administrative agent and lender. The short-term loan was subject to 0.25% quarterly amortization payments, and accrued interest at SOFR plus 0.90%. The short-term loan matured in November 2022 and we repaid the remaining principal balance of this loan in full at the maturity date. Senior Secured Credit Facilities As of March 31, 2023, the senior secured credit facilities consisted of (i) a secured term loan credit facility ("Term Loan Facility") and (ii) a $2.0 billion asset based loan facility ("ABL Revolver"). The senior secured credit facilities contain various affirmative covenants, including covenants with respect to our financial statements, litigation and other reporting requirements, insurance, payment of taxes, employee benefits, and (subject to certain limitations) causing new subsidiaries to pledge collateral and guaranty our obligations. The senior secured credit facilities also include various customary negative covenants and events of default, including limitations on our ability to incur additional indebtedness; sell certain assets; enter into sale and leaseback transactions; make investments, loans, and advances; pay dividends or returns of capital and distributions beyond certain amounts; engage in mergers, amalgamations, or consolidations; engage in certain transactions with affiliates; and prepay certain indebtedness. The Term Loan Facility also contains a financial maintenance covenant that prohibits Novelis' senior secured net leverage ratio as of the last day of each fiscal quarter period as measured on a rolling four quarter basis from exceeding 3.50 to 1.00, subject to customary equity cure rights. The senior secured credit facilities include a cross-default provision under which lenders could accelerate repayment of the loans if a payment or non-payment default arises under any other indebtedness with an aggregate principal amount of more than $100 million (or, in the case of the Term Loan Facility, under the ABL Revolver regardless of the amount outstanding). The senior secured credit facilities are guaranteed by the Company's direct parent, AV Minerals (Netherlands) N.V., and certain of the Company's direct and indirect subsidiaries and are secured by a pledge of substantially all of the assets of the Company and the guarantors. Term Loan Facility The Term Loan Facility requires customary mandatory prepayments with excess cash flow, other asset sale proceeds, casualty event proceeds, and proceeds of prohibited indebtedness, all subject to customary reinvestment rights and exceptions. The loans under the Term Loan Facility may be prepaid, in full or in part, at any time at Novelis' election without penalty or premium. The Term Loan Facility allows for additional term loans to be issued in an amount not to exceed $300 million (or its equivalent in other currencies) plus an unlimited amount if, after giving effect to such incurrences on a pro forma basis, the secured net leverage ratio does not exceed 3.00 to 1.00. The Term Loan Facility also allows for additional term loans to be issued in an amount to refinance loans outstanding under the Term Loan Facility. The lenders under the Term Loan Facility have not committed to provide any such additional term loans. On March 31, 2023, Novelis amended the Term Loan Facility, primarily to modify the reference rate used to determine interest from LIBOR to SOFR. Term loans under the Term Loan Facility will, beginning with the interest period commencing June 30, 2023, accrue interest at SOFR plus a 0.15% credit spread adjustment ("Adjusted SOFR") plus a spread of 1.75% in the case of the 2020 Term Loans, as defined below, or a spread of 2.00% in the case of the 2021 Term Loans, as defined below. During fiscal 2021, the Company adopted the practical expedient for Reference Rate Reform related to its debt arrangements and as such, this amendment is treated as a continuation of the existing debt agreement and no gain or loss on the modification was recorded. The Company did not record any gains or losses on the conversion of the reference rate for the borrowings under the Term Loan Facility from LIBOR to SOFR. As of March 31, 2023, we were in compliance with the covenants for our Term Loan Facility. 2020 Term Loans In April 2020, we borrowed $775 million of term loans due January 2025 (the "2020 Term Loans") under our Term Loan Facility. The proceeds of the 2020 Term Loans were used to pay a portion of the consideration payable in the acquisition of Aleris (including the repayment of Aleris' outstanding indebtedness) as well as fees and expenses related to the acquisition of the 2020 Term Loans. We incurred debt issuance costs of $15 million for the 2020 Term Loans, which will be amortized as an increase to interest expense and amortization of debt issuance costs over the term of the loan. The 2020 Term Loans mature on January 21, 2025 and are subject to 0.25% quarterly amortization payments. From April 2020 to immediately prior to the interest period commencing June 30, 2023, the 2020 Term Loans accrued and will continue to accrue interest at LIBOR plus 1.75%. Beginning with the interest period commencing June 30, 2023, the 2020 Term Loans will accrue interest at Adjusted SOFR plus 1.75%. 2021 Term Loans In March 2021, we borrowed $480 million of term loans due March 2028 (the "2021 Term Loans") under our Term Loan Facility, with an additional $20 million being borrowed under the 2021 Term Loans in April 2021. We incurred debt issuance costs of $9 million for the 2021 Term Loans, which will be amortized as an increase to interest expense and amortization of debt issuance costs over the term of the loan. The 2021 Term Loans mature on March 31, 2028 and are subject to 0.25% quarterly amortization payments. From April 2020 to immediately prior to the interest period commencing June 30, 2023, the 2021 Term Loans accrue interest at LIBOR plus 2.00%. Beginning with the interest period commencing June 30, 2023, the 2021 Term Loans will accrue interest at Adjusted SOFR plus 2.00%. The proceeds of the 2021 Term Loans were applied to repay a portion of the 2017 Term Loans. ABL Revolver As of March 31, 2023, the commitments under our senior secured ABL Revolver are $2.0 billion. In October 2021, Novelis amended the ABL Revolver facility. Prior to the USD LIBOR transition date, loans denominated in USD under the ABL Revolver accrued interest at a rate of LIBOR plus a spread of 1.25% to 1.75% based on excess availability. The amendment provides for replacement reference rates, as applicable, based on the currency of the loan, as well as applicable spreads on and after the USD LIBOR transition date. The USD LIBOR transition date is defined as the earlier of (a) when the ICE Benchmark Administration ceases to provide the USD LIBOR and there is no available tenor of USD LIBOR or the Financial Conduct Authority announces all available tenors of USD LIBOR are no longer representative or (b) an early opt-in effective date. In April 2022, Novelis amended the ABL Revolver facility to increase the limit on committed letters of credit under the facility to $275 million. There were no material costs incurred or accounting impacts as a result of this amendment. In August 2022, Novelis amended the ABL Revolver facility to, among other things, increase the commitment under the ABL Revolver by $500 million to $2.0 billion and extend the maturity of the ABL Revolver until August 18, 2027. The amendment provides that new borrowings under the ABL Revolver facility made subsequent to the date of the amendment will incur interest at Term SOFR, EURIBOR, SONIA or SARON, as applicable based on the currency of the loan, plus a spread of 1.10% to 1.60% based on excess availability. The ABL Revolver facility also permits us to elect to borrow USD loans that accrue interest at a base rate (determined based on the greatest of one month Term SOFR plus 1.00%, a prime rate or an adjusted federal funds rate) plus a prime spread of 0.10% to 0.60% based on excess availability. As a result of this debt modification, the Company incurred $7 million of financing fees, which will be amortized over the term of the loan. The ABL Revolver has a provision that allows the existing commitments under the ABL Revolver to be increased by an additional $750 million. The lenders under the ABL Revolver have not committed to provide any such additional commitments. The ABL Revolver has various customary covenants including maintaining a specified minimum fixed charge coverage ratio of 1.25 to 1.0 if an event of default has occurred and is continuing and/or excess availability is less than the greater of (1) $150 million and (2) 10% of the lesser of the total ABL Revolver commitment and the borrowing base. The ABL Revolver matures on August 18, 2027, provided that in the event that the Term Loan Facility or certain other indebtedness is outstanding 60 days prior to its maturity (and not refinanced with a maturity date later than February 15, 2028), then the ABL Revolver will mature 60 days prior to the maturity date for such other indebtedness, as applicable; unless excess availability under the ABL Revolver is at least (1) 17.5% of the lesser of the total ABL Revolver commitment and the borrowing base or (2) 12.5% of the lesser of the total ABL Revolver commitment and the borrowing base, while also maintaining the minimum fixed charge ratio test of at least 1.25 to 1. As of March 31, 2023, we were in compliance with the covenants for our ABL Revolver. As of March 31, 2023, we had $463 million in borrowings under our ABL Revolver. We utilized $40 million of our ABL Revolver for letters of credit. We had availability of $970 million on the ABL Revolver, including $235 million of remaining availability which can be utilized for letters of credit. Zhenjiang Loans Through the Aleris acquisition, the Company assumed $141 million in debt borrowed by Aleris Aluminum (Zhenjiang) Co., Ltd. under a loan agreement comprised of non-recourse multi-currency secured term loan facilities and a revolving facility (collectively the "Zhenjiang Loans"), which consisted of a $29 million USD term loan facility, a $112 million (RMB 791 million) term loan facility (collectively, the "Zhenjiang Term Loans"), and a revolving facility (the "Zhenjiang Revolver"). There were no balances outstanding under the Zhenjiang Revolver as of the date of the Aleris acquisition. In May 2021, the Zhenjiang Term Loans were repaid in full, and the Zhenjiang Revolver matured having had no borrowings since the Aleris acquisition. As such, the covenants under the agreement are no longer in effect. Senior Notes The Senior Notes are guaranteed, jointly and severally, on a senior unsecured basis, by Novelis Inc. and certain of its subsidiaries. The Senior Notes contain customary covenants and events of default that will limit our ability and, in certain instances, the ability of certain of our subsidiaries to incur additional debt and provide additional guarantees; pay dividends or return capital beyond certain amounts and make other restricted payments; create or permit certain liens; make certain asset sales; use the proceeds from the sales of assets and subsidiary stock; create or permit restrictions on the ability of certain of Novelis' subsidiaries to pay dividends or make other distributions to Novelis or certain of Novelis' subsidiaries, as applicable; engage in certain transactions with affiliates; enter into sale and leaseback transactions; designate subsidiaries as unrestricted subsidiaries; and consolidate, merge, or transfer all or substantially all of our assets and the assets of certain of our subsidiaries. During any future period in which either Standard & Poor's Ratings Group, Inc. or Moody's Investors Service, Inc. have assigned an investment grade credit rating to the Senior Notes and no default or event of default under the indenture has occurred and is continuing, certain of the covenants will be suspended. The Senior Notes include customary events of default, including a cross-acceleration event of default. The Senior Notes also contain customary call protection provisions for our bondholders that extend through November 2023 for the 3.250% Senior Notes due November 2026, through April 2024 for the 3.375% Senior Notes due April 2029, through January 2025 for the 4.750% Senior Notes due January 2030, and through August 2026 for the 3.875% Senior Notes due August 2031. As of March 31, 2023, we were in compliance with the covenants for our Senior Notes. 5.875% Senior Notes due September 2026 In September 2016, Novelis Corporation, an indirect wholly owned subsidiary of Novelis Inc., issued $1.5 billion in aggregate principal amount of 5.875% Senior Notes due September 2026. The proceeds from the August 2021 issuance of the 2026 Senior Notes and the 2031 Senior Notes, as defined below, were used to fully fund the redemption of the 5.875% Senior Notes due September 2026. As a result, the 5.875% Senior Notes due September 2026 were no longer outstanding as of March 31, 2023. 2026 Senior Notes In August 2021, Novelis Corporation, an indirect wholly owned subsidiary of Novelis Inc., issued $750 million in aggregate principal amount of 3.250% Senior Notes due November 2026 (the "2026 Senior Notes"). The 2026 Senior Notes mature on November 15, 2026 and are subject to semi-annual interest payments that will accrue at a rate of 3.250% per year. The net proceeds of the offering, together with cash on hand, were used to (i) fund the redemption of a portion of the 5.875% Senior Notes due September 2026, plus the redemption premium and accrued and unpaid interest thereon and (ii) pay certain fees and expenses in connection with the foregoing and the offering of the notes. We incurred debt issuance costs of $11 million for the 2026 Senior Notes, which are amortized as an increase to interest expense and amortization of debt issuance costs over the term of the note. 2029 Senior Notes In March 2021, Novelis Sheet Ingot GmbH, an indirect wholly owned subsidiary of Novelis Inc., organized under the laws of Ireland, issued €500 million in aggregate principal amount of 3.375% Senior Notes due April 2029 (the "2029 Senior Notes"). The 2029 Senior Notes are subject to semi-annual interest payments and mature on April 15, 2029. The proceeds were used to pay down a portion of the 2017 Term Loans, plus accrued and unpaid interest. In addition, we intend to allocate an amount equal to the net proceeds received from this issuance to finance and/or refinance new and/or existing eligible green projects, which are currently contemplated to consist of renewable energy or pollution prevention and control type projects. We incurred debt issuance costs of $13 million for the 2029 Senior Notes, which are amortized as an increase to interest expense and amortization of debt issuance costs over the term of the note. 2030 Senior Notes In January 2020, Novelis Corporation, an indirect wholly owned subsidiary of Novelis Inc., issued $1.6 billion in aggregate principal amount of 4.750% Senior Notes due January 2030 (the "2030 Senior Notes"). The 2030 Senior Notes are subject to semi-annual interest payments and mature on January 30, 2030. 2031 Senior Notes In August 2021, Novelis Corporation, an indirect wholly owned subsidiary of Novelis Inc., issued $750 million in aggregate principal amount of 3.875% Senior Notes due August 2031 (the "2031 Senior Notes"). The 2031 Senior Notes mature on August 15, 2031 and are subject to semi-annual interest payments that will accrue at a rate of 3.875% per year. The net proceeds of the offering, together with cash on hand, were used to (i) fund the redemption a portion of the 5.875% Senior Notes due September 2026, plus the redemption premium and accrued and unpaid interest thereon and (ii) pay certain fees and expenses in connection with the foregoing and the offering of the notes. We incurred debt issuance costs of $11 million for the 2031 Senior Notes, which are amortized as an increase to interest expense and amortization of debt issuance costs over the term of the note. China Bank Loans In September 2019, we entered into a credit agreement with the Bank of China to provide up to CNY 500 million in unsecured loans to support certain capital expansion projects in China. As of March 31, 2023, we had $64 million (CNY 440 million) of borrowings on our China bank loans. Brazil Loans In December 2021, we borrowed $30 million and $20 million of bank loans in Brazil due June 16, 2023 and December 15, 2023, respectively. These bank loans are subject to 1.80% interest due in full at the respective maturity date. Loss on Extinguishment of Debt, Net During fiscal 2021, we incurred $14 million in loss on extinguishment of debt, net, primarily related to the partial repayment of our 2017 Term Loans during fiscal 2021 and the early repayment of certain short-term debt. During fiscal 2022, we recorded $64 million in loss on extinguishment of debt, net. This primarily related to the write-off of unamortized debt issuance costs of $13 million and a $51 million cash payment of a redemption premium for the redemption of our 5.875% Senior Notes, due September 2026. Additionally, a loss on extinguishment of debt of $2 million was recorded as a result of the repayment of our 2017 Term Loans, which was offset by a gain on extinguishment of debt of $2 million resulting from the repayment of the Zhenjiang Term Loans. |

14. SHARE-BASED COMPENSATION | 14. SHARE-BASED COMPENSATION The Company's Board of Directors has authorized long-term incentive plans, under which Hindalco SARs, Novelis SARs, phantom RSUs, and Novelis PUs are granted to certain executive officers and key employees. The Hindalco SARs vest at the rate of 33% per year, subject to the achievement of an annual performance target. Fiscal years ended March 31, 2016 SARs expire in May of the seventh year from the original grant date, while the fiscal year ended March 31, 2017 and onwards SARs expire seven years from their original grant date. The performance criterion for vesting of the Hindalco SARs is based on the actual overall Novelis operating EBITDA compared to the target established and approved each fiscal year. The minimum threshold for vesting each year is 75% of each annual target operating EBITDA. Given that the performance criterion is based on an earnings target in a future period for each fiscal year, the grant date of the awards for accounting purposes is generally not established until the performance criterion has been defined. Each Hindalco SAR is to be settled in cash based on the difference between the market value of one Hindalco share on the date of grant and the market value on the date of exercise. Each Novelis SAR is to be settled in cash based on the difference between the fair value of one Novelis phantom share on the original date of grant and the fair value of a phantom share on the date of the exercise. The amount of cash paid to settle Hindalco SARs and Novelis SARs is limited to three times the target payout, depending on the plan year. The Hindalco SARs and Novelis SARs do not transfer any shareholder rights in Hindalco or Novelis to a participant. The Hindalco SARs and Novelis SARs are classified as liability awards and are remeasured at fair value each reporting period until the SARs are settled. The RSUs are based on Hindalco's stock price. The RSUs vest either in full three years from the grant date or 33% per year over three years, subject to continued employment with the Company, but are not subject to performance criteria. Each RSU is to be settled in cash equal to the market value of one Hindalco share. The payout on the RSUs is limited to three times the market value of one Hindalco share measured on the original date of grant. The RSUs are classified as liability awards and expensed over the requisite service period (three years) based on the Hindalco stock price as of each balance sheet date. Total compensation expense related to Hindalco SARs, Novelis SARs, and RSUs under the plans for the respective periods is presented in the table below. These amounts are included in selling, general and administrative expenses in our consolidated statements of operations. As the performance criteria for the fiscal years ending March 31, 2024, 2025, and 2026 have not yet been established, measurement periods for Hindalco SARs relating to those periods have not yet commenced. As a result, only compensation expense for vested and current year Hindalco SARs and Novelis SARs has been recorded. in millions Fiscal 2023 Fiscal 2022 Fiscal 2021 Total compensation expense $ 15 $ 40 $ 41 The table below shows the RSUs activity for fiscal 2023.

During fiscal 2021, we granted 5,016,919 RSUs with a grant date fair value of INR 118.34, and the aggregate intrinsic value of RSUs exercised was $4 million. Total cash payments made to settle RSUs were $15 million, $17 million, and $4 million in fiscal 2023, fiscal 2022, and fiscal 2021, respectively. As of March 31, 2023, unrecognized compensation expense related to the RSUs was $15 million, which will be recognized over the remaining weighted average vesting period of 1.9 years.

During fiscal 2021, we granted 6,934,923 Hindalco SARs with a grant date fair value of INR 118.11, and the aggregate intrinsic value of Hindalco SARs exercised was $9 million. The cash payments made to settle Hindalco SAR liabilities were $8 million, $24 million, and $9 million in fiscal 2023, fiscal 2022, and fiscal 2021, respectively. As of March 31, 2023, unrecognized compensation expense related to the non-vested Hindalco SARs (assuming all future performance criteria are met) was $5 million that are expected to be recognized over a weighted average period of 1.3 years. The table below shows the Novelis SARs activity for fiscal 2023.

In fiscal 2021, the aggregate intrinsic value of Novelis SARs exercised was $1 million. There were no cash payments made to settle Novelis SAR liabilities for fiscal 2022. In fiscal 2021 there were $1 million of cash payments made to settle Novelis SAR liabilities. The fair value of each unvested Hindalco SAR was estimated using the following assumptions. Fiscal 2023 Fiscal 2022 Fiscal 2021 Risk-free interest rate 3.11%-7.24% 3.59%-6.58% 3.32%-6.18% Dividend yield 1.03 % 0.48 % 0.32 % Volatility 32%-47% 39%-50% 40%-57% The fair value of each unvested Novelis SAR was estimated using the following assumptions.

The fair value of each of these call options was determined using the Monte Carlo Simulation model. We used historical stock price volatility data of Hindalco on the National Stock Exchange of India to determine expected volatility assumptions. The risk-free interest rate is based on Indian treasury yields interpolated for a time period corresponding to the remaining contractual life. The forfeiture rate is estimated based on actual historical forfeitures. The dividend yield is estimated to be the annual dividend of the Hindalco stock over the remaining contractual lives of the Hindalco SARs. The value of each vested Hindalco SAR is remeasured at fair value each reporting period based on the excess of the current stock price over the exercise price, not to exceed the maximum payout as defined by the plans. The fair value of the Hindalco SARs is being recognized over the requisite performance and service period of each tranche, subject to the achievement of any performance criteria. |

Retirement Benefits [Abstract] | |
15. POSTRETIREMENT BENEFIT PLANS | 15. POSTRETIREMENT BENEFIT PLANS Our pension obligations relate to: (1) funded defined benefit pension plans in the U.S., Canada, Switzerland, and the U.K., (2) funded and unfunded defined benefit pension plans in Germany, (3) unfunded lump sum indemnities payable upon retirement to employees in France and Italy, and (4) partially funded lump sum indemnities in South Korea. Our other postretirement obligations (other benefits, as shown in certain tables below) include unfunded health care and life insurance benefits provided to retired employees in the U.S., Canada, and Brazil. We have combined our domestic (i.e. Canadian Plans) and foreign (i.e. all plans other than Canadian Plans) postretirement benefit plan disclosures because our domestic benefit obligation is not significant as compared to our total benefit obligation. Our foreign benefit obligation is 97% of the total benefit obligation, and the assumptions used to value domestic and foreign plans were not significantly different. The Company recognizes actuarial gains and losses and prior service costs in the consolidated balance sheet and recognizes changes in these amounts during the year in which changes occur through other comprehensive income (loss). The Company uses various assumptions when computing amounts relating to its defined benefit pension plan obligations and their associated expenses (including the discount rate and the expected rate of return on plan assets). During the second quarter of fiscal 2021, Novelis announced the freeze of future benefit accruals under the Novelis Pension Plan and the Terre Haute Pension Plan in the U.S., effective December 31, 2020. Novelis elected to remeasure both plans' plan assets and obligations as of August 31, 2020, which was the nearest calendar month-end date to the announcements of said freezes. A curtailment loss of $1 million was recorded related to the Terre Haute plan during fiscal 2021. During the first quarter of fiscal 2022, Novelis announced the freeze of future benefit accruals under the Canada Pension Plan, effective for union participants as of December 31, 2021 and non-union participants as of December 31, 2023. Novelis remeasured the plan's assets and obligations as of April 30, 2021, which was the nearest calendar month-end to the announcement of this freeze. A curtailment gain of $3 million was recorded related to the Canada Pension Plan during fiscal 2022. During the second quarter of fiscal 2022, Novelis entered into an agreement to transfer the liabilities associated with a portion of the retirees and beneficiaries of the Canada Novelis Pension Plan to an insurer through a purchase of buy-out annuities. The premium payment was made to the insurer on August 10, 2021. Novelis remeasured the plan's assets and obligations as of July 31, 2021, which was the nearest calendar month-end to the premium payment for this settlement. The insurer took responsibility for the payments to these transferred members effective November 1, 2021. As a result of this transaction, a settlement gain of $4 million was recorded during fiscal 2022. Employer Contributions to Plans For pension plans, our policy is to fund an amount required to provide for contractual benefits attributed to service to-date and amortize unfunded actuarial liabilities typically over periods of 15 years or less. We also participate in savings plans in Canada and the U.S., as well as defined contribution pension plans in the U.S., the U.K., Canada, Germany, Italy, Switzerland, and Brazil. We contributed the following amounts to all plans. in millions Fiscal 2023 Fiscal 2022 Fiscal 2021 Funded pension plans $ 22 $ 49 $ 72 Unfunded pension plans 15 17 17 Savings and defined contribution pension plans 54 51 40 Total contributions $ 91 $ 117 $ 129 In fiscal 2021, contributions to funded pension plans of $5 million and unfunded pension plans of $1 million are attributable to discontinued operations. During fiscal 2024, we expect to contribute $20 million to our funded pension plans, $17 million to our unfunded pension plans, and $55 million to our savings and defined contribution pension plans. Benefit Obligations, Fair Value of Plan Assets, Funded Status, and Amounts Recognized in Financial Statements The increase in the discount rates in fiscal 2023, as compared to fiscal 2022, was the primary driver of actuarial gains in fiscal 2023. The following tables present the change in benefit obligation, change in fair value of plan assets, and the funded status for pension and other benefits.

Actuarial Assumptions and Sensitivity Analysis The weighted average assumptions used to determine benefit obligations and net periodic benefit cost for the respective periods are listed in the table below. Pension Benefit Plans Other Benefit Plans Fiscal 2023 Fiscal 2022 Fiscal 2021 Fiscal 2023 Fiscal 2022 Fiscal 2021 Weighted average assumptions used to determine benefit obligations Discount rate 4.5 % 3.1 % 2.5 % 5.5 % 4.0 % 3.4 % Average compensation growth 3.1 3.1 3.1 3.0 3.0 3.0 Weighted average assumptions used to determine net periodic benefit cost Discount rate 3.1 % 2.5 % 2.6 % 4.0 % 3.4 % 3.4 % Average compensation growth 3.1 3.1 3.1 3.0 3.0 3.3 Expected return on plan assets 4.8 4.9 5.1 — — — Cash balance interest crediting rate 1.4 0.8 0.5 — — — In selecting the appropriate discount rate for each plan, for pension and other postretirement plans in Canada, the U.S., the U.K., and other eurozone countries, we used spot rate yield curves and individual bond matching models. For other countries, we used published long-term high quality corporate bond indices with adjustments made to the index rates based on the duration of the plans' obligation. In estimating the expected return on assets of a pension plan, consideration is given primarily to its target allocation, the current yield on long-term bonds in the country where the plan is established, and the historical risk premium of equity or real estate over long-term bond yields in each relevant country. The approach is consistent with the principle that assets with higher risk provide a greater return over the long term. The expected long-term rate of return on plan assets is 6.1% in fiscal 2024. We provide unfunded health care and life insurance benefits to our retired employees in Canada, the U.S., the U.K., and Brazil, for which we paid $6 million, $6 million, and $7 million in fiscal 2023, 2022, and 2021, respectively. The assumed health care cost trend used for measurement purposes is 7.4% for fiscal 2024, decreasing gradually to 5.1% in 2033 and remaining at that level thereafter. In addition, we provide post-employment benefits, including disability, early retirement, and continuation of benefits (medical, dental, and life insurance) to our former or inactive employees, which are accounted for on the accrual basis in accordance with ASC 712. As of March 31, 2023, other long–term liabilities and accrued expenses and other current liabilities on our consolidated balance sheets include $6 million and $5 million, respectively, for these benefits. Comparatively, as of March 31, 2022, other long–term liabilities and accrued expenses and other current liabilities on our consolidated balance sheets include $10 million and $5 million, respectively, for these benefits. Investment Policy and Asset Allocation The Company's overall investment strategy is to achieve a mix of approximately 50% of investments for long-term growth (equities, real estate) and 50% for near-term benefit payments (debt securities, other) with a wide diversification of asset categories, investment styles, fund strategies, and fund managers. Since most of the defined benefit plans are closed to new entrants, we expect this strategy to gradually shift more investments toward near-term benefit payments. Each of our funded pension plans is governed by an Investment Fiduciary, who establishes an investment policy appropriate for the pension plan. The Investment Fiduciary is responsible for selecting the asset allocation for each plan, monitoring investment managers, monitoring returns versus benchmarks, and monitoring compliance with the investment policy. The targeted allocation ranges by asset class and the actual allocation percentages for each class are listed in the table below. Asset Category Target Allocation Ranges Allocation in Aggregate as of March 31, 2023 2022 Equity 10-45% 27 % 32 % Fixed income 20-89% 37 % 49 % Real estate 4-25% 7 % 3 % Other 1-100% 29 % 16 % Fair Value of Plan Assets The following pension plan assets are measured and recognized at fair value on a recurring basis. See Note 19 – Fair Value Measurements for a description of the fair value hierarchy. The U.S. and Canadian pension plan assets are invested exclusively in commingled funds and measured at net asset value, and the U.K., Switzerland, and South Korea pension plan assets are invested in both direct investments (Levels 1 and 2) and commingled funds (Level 2).

Metal We use derivative instruments to preserve our conversion margins and manage the timing differences associated with metal price lag. We use over-the-counter derivatives indexed to the LME (referred to as our "aluminum derivative forward contracts") to reduce our exposure to fluctuating metal prices associated with the period of time between the pricing of our purchases of inventory and the pricing of the sale of that inventory to our customers, which is known as "metal price lag." We also purchase forward LME aluminum contracts simultaneously with our sales contracts with customers that contain fixed metal prices. These LME aluminum forward contracts directly hedge the economic risk of future metal price fluctuations to better match the selling price of the metal with the purchase price of the metal. The volatility in local market premiums also results in metal price lag. Price risk arises due to fluctuating aluminum prices between the time the sales order is committed and the time the order is shipped. We identify and designate certain LME aluminum forward purchase contracts as cash flow hedges of the metal price risk associated with our future metal purchases that vary based on changes in the price of aluminum. Generally, such exposures do not extend beyond one year in length. The average duration of those contracts is less than one year. Price risk exposure arises due to the timing lag between the LME based pricing of raw material aluminum purchases and the LME based pricing of finished product sales. We identify and designate certain LME aluminum forward sales contracts as cash flow hedges of the metal price risk associated with our future metal sales that vary based on changes in the price of aluminum. Generally, such exposures do not extend beyond two years in length. The average duration of those contracts is less than one year. In addition to aluminum, we entered into LME copper and zinc forward contracts, as well as local market premiums forward contracts. As of March 31, 2023 and March 31, 2022, the fair value of these contracts were an asset of less than $1 million and $4 million, respectively. These contracts are undesignated, with an average duration of less than one year. The following table summarizes our notional amount. March 31, in kt 2023 2022 Hedge type Purchase (sale) Cash flow purchases 1 6 Cash flow sales (699) (910) Not designated (144) (16) Total, net (842) (920) Foreign Currency We use foreign exchange forward contracts and cross-currency swaps to manage our exposure to changes in exchange rates. These exposures arise from recorded assets and liabilities, firm commitments, and forecasted cash flows denominated in currencies other than the functional currency of certain operations. We use foreign currency contracts to hedge expected future foreign currency transactions, which include capital expenditures. These contracts cover the same periods as known or expected exposures. We had total notional amounts of $1.2 billion and $1.3 billion in outstanding foreign currency forwards designated as cash flow hedges as of March 31, 2023 and 2022, respectively. As of March 31, 2023, and 2022, we had outstanding foreign currency exchange contracts with a total notional amount of $1.7 billion and $1.7 billion, respectively, to primarily hedge balance sheet remeasurement risk, which were not designated as hedges. Contracts representing the majority of this notional amount will mature by the first and second quarter of fiscal 2024 and offset the remeasurement impact. Energy We use natural gas forward purchase contracts to manage our exposure to fluctuating energy prices in North America. We had a notional of 7 million MMBtu designated as cash flow hedges as of March 31, 2023, and the fair value was liability of less than $1 million. There was a notional of 10 million MMBtu of natural gas forward purchase contracts designated as cash flow hedges as of March 31, 2022, and the fair value was an asset of $25 million. As of March 31, 2023 and 2022, we had notionals of less than 1 million MMBtu of forward contracts that were not designated as hedges. The fair value of forward contracts not designated as hedges as of March 31, 2023, was a liability of less than $1 million and as of March 31, 2022 was an asset of $2 million. The average duration of these contracts is two years in length. We use diesel fuel forward purchase contracts to manage our exposure to fluctuating fuel prices in North America and Europe. We had a notional of 1 million gallons designated as cash flow hedges as of March 31, 2023, and the fair value was liability of less than $1 million. There was a notional of 4 million gallons designated as cash flow hedges as of March 31, 2022, and the fair value was an asset of $3 million. As of March 31, 2023, and 2022 we had notional of less than 1 million MT of forward contracts that were not designated as hedges. The fair value of forward contracts not designated as hedges as of March 31, 2023, was a liability of less than $1 million and as of March 31, 2022 was an asset of $1 million. The average duration of all diesel fuel forward purchase contracts is less than one year in length.

Fair Value Disclosures [Abstract] | |
19. FAIR VALUE MEASUREMENTS | 19. FAIR VALUE MEASUREMENTS We record certain assets and liabilities, primarily derivative instruments, on our consolidated balance sheets at fair value. We also disclose the fair values of certain financial instruments, including debt and loans receivable, which are not recorded at fair value. Our objective in measuring fair value is to estimate an exit price in an orderly transaction between market participants on the measurement date. We consider factors such as liquidity, bid/offer spreads, and nonperformance risk, including our own nonperformance risk, in measuring fair value. We use observable market inputs wherever possible. To the extent observable market inputs are not available, our fair value measurements will reflect the assumptions used. We grade the level of the inputs and assumptions used according to a three-tier hierarchy: Level 1 — Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities we have the ability to access at the measurement date. Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 — Unobservable inputs for which there is little or no market data, which require us to develop our own assumptions based on the best information available as to what market participants would use in pricing the asset or liability. The following describes the valuation methodologies we used to measure our various financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Derivative Contracts For certain derivative contracts with fair values based upon trades in liquid markets, such as aluminum, zinc, copper, foreign exchange, natural gas, and diesel fuel forward contracts and options, valuation model inputs can generally be verified and valuation techniques do not involve significant judgment. The fair values of such financial instruments are generally classified within Level 2 of the fair value hierarchy. The majority of our derivative contracts are valued using industry-standard models with observable market inputs as their basis, such as time value, forward interest rates, volatility factors, and current (spot) and forward market prices. We generally classify these instruments within Level 2 of the valuation hierarchy. Such derivatives include interest rate swaps, cross-currency swaps, foreign currency contracts, aluminum, copper, and zinc forward contracts, and natural gas and diesel fuel forward contracts. For Level 2 and 3 of the fair value hierarchy, where appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads, and credit considerations (nonperformance risk). We regularly monitor these factors along with significant market inputs and assumptions used in our fair value measurements and evaluate the level of the valuation input according to the fair value hierarchy. This may result in a transfer between levels in the hierarchy from period to period. As of March 31, 2023 and March 31, 2022, we did not have any Level 1 derivative contracts. No amounts were transferred between levels in the fair value hierarchy. All of the Company's derivative instruments are carried at fair value in the statements of financial position prior to considering master netting agreements. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date and are reported gross. The following table presents our derivative assets and liabilities which were measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy as of March 31, 2023, and March 31, 2022. The table below also discloses the net fair value of the derivative instruments after considering the impact of master netting agreements.

In addition to our derivative assets and liabilities held at fair value, our consolidated balance sheet as of March 31, 2022 includes a Level 3 receivable related to the contingent consideration for the sale of Duffel to ALVANCE. Upon closing on September 30, 2020, we recorded a receivable at a fair value of €93 million ($109 million) measured based on the anticipated outcome, timeline of arbitration of greater than one year, and a discount rate of 5%. During the first quarter of fiscal 2022, Novelis marked all outstanding receivables related to the sale of Duffel to an estimated fair value of €45 million ($53 million), which resulted in a loss of €51 million ($61 million) recorded in loss from discontinued operations, net of tax. As further discussed in Note 3 – Discontinued Operations , in December 2022, the Company reached an agreement with the current owner of Duffel, where the outstanding contingent consideration receivable was settled in exchange for €5 million ($5 million) in cash and a note receivable in the amount of €40 million ($41 million). The note receivable is not carried at fair value, but we will continue to assess its collectibility on a quarterly basis. The fair value of the note receivable is determined using Level 2 inputs and is materially consistent with the carrying value. Financial Instruments Not Recorded at Fair Value The table below presents the estimated fair value of certain financial instruments not recorded at fair value on a recurring basis. The table excludes finance leases and short-term financial assets and liabilities for which we believe carrying value approximates fair value. We value long-term receivables and long-term debt using Level 2 inputs. Valuations are based on either market and/or broker ask prices when available or on a standard credit adjusted discounted cash flow model using market observable inputs.

21. INCOME TAXES | 21. INCOME TAXES We are subject to Canadian and U.S. federal, state, and local income taxes as well as other foreign income taxes. The domestic (Canada) and foreign components of our income from continuing operations before income tax provision (and after removing our equity in net income of non-consolidated affiliates) are as follows. in millions Fiscal 2023 Fiscal 2022 Fiscal 2021 Domestic (Canada) $ 61 $ 106 $ (15) Foreign (all other countries) 729 1,185 710 Pre-tax income before equity in net income of non-consolidated affiliates $ 790 $ 1,291 $ 695 The components of our income tax provision are as follows. in millions Fiscal 2023 Fiscal 2022 Fiscal 2021 Current provision: Domestic (Canada) $ 3 $ 9 $ 6 Foreign (all other countries) 189 245 183 Total current $ 192 $ 254 $ 189 Deferred provision: Domestic (Canada) $ 9 $ (54) $ — Foreign (all other countries) (54) 81 49 Total deferred $ (45) $ 27 $ 49 Income tax provision $ 147 $ 281 $ 238 The reconciliation of the Canadian statutory tax rates to our effective tax rates are shown below. in millions, except percentages Fiscal 2023 Fiscal 2022 Fiscal 2021 Pre-tax income before equity in net income of non-consolidated affiliates $ 790 $ 1,291 $ 695 Canadian statutory tax rate 25 % 25 % 25 % Provision at the Canadian statutory rate $ 198 $ 323 $ 174 Increase (decrease) for taxes on income (loss) resulting from: Exchange translation items 9 14 19 Exchange remeasurement of deferred income taxes (4) 10 (5) Change in valuation allowances (36) (66) 23 Tax credits (36) (46) (23) Income items not subject to tax (13) (15) (1) State tax expense, net 3 (2) (5) Enacted tax rate changes 3 (6) (2) Tax rate differences on foreign earnings 19 65 48 Uncertain tax positions 3 5 6 Prior year adjustments (13) (6) (1) Income tax settlements — — 4 Non-deductible expenses and other, net 14 5 1 Income tax provision $ 147 $ 281 $ 238 Effective tax rate 19 % 22 % 34 % Our effective tax rate differs from the Canadian statutory rate for fiscal 2023 primarily due to the following factors: the results of operations taxed at foreign statutory tax rates that differ from the 25% Canadian tax rate, including withholding taxes; changes to the Brazilian real foreign exchange rate; changes in valuation allowances; and the availability of tax credits. We earn tax credits in a number of the jurisdictions in which we operate. These are primarily composed of foreign tax credits in Canada of $21 million, empire zone credits in New York of $2 million, and R&D credits in the U.S. of $8 million. The impact on our income tax provision of credits during fiscal 2023 was a benefit of $36 million. However, legislation enacted in New York state on March 31, 2014, established a zero percent statutory income tax rate for manufacturers. As a result, the current year empire zone credits in New York are offset with a corresponding valuation allowance of $2 million. Deferred Income Taxes Deferred income taxes recognize the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the carrying amounts used for income tax purposes as well as the impact of available net operating loss and tax credit carryforwards. These items are stated at the enacted tax rates that are expected to be in effect when taxes are actually paid or recovered. Our deferred income tax assets and deferred income tax liabilities are as follows. March 31, in millions 2023 2022 Deferred income tax assets: (1) Provisions not currently deductible for tax purposes $ 410 $ 505 Tax losses/benefit carryforwards, net 924 998 Depreciation and amortization 97 93 Other assets 38 28 Total deferred income tax assets 1,469 1,624 Less: valuation allowance (711) (763) Net deferred income tax assets $ 758 $ 861 Deferred income tax liabilities: (1) Depreciation and amortization $ 557 $ 555 Inventory valuation reserves 153 199 Monetary exchange gains, net 29 28 Other liabilities 141 79 Total deferred income tax liabilities $ 880 $ 861 Net deferred income tax liabilities $ 122 $ — _________________________ (1) Certain amounts for 2022 were reclassified to conform with current period presentation, specifically derivatives and pensions. ASC 740 requires that we reduce our deferred income tax assets by a valuation allowance if, based on the weight of the available evidence, it is more likely than not that all or a portion of a deferred tax asset will not be realized. After consideration of all evidence, both positive and negative, management concluded that it is more likely than not that we will be unable to realize a portion of our deferred tax assets and that valuation allowances of $711 million and $763 million were necessary as of March 31, 2023, and 2022, respectively. We continue to maintain valuation allowances in Canada and certain foreign jurisdictions primarily related to tax losses where we believe it is more likely than not that we will be unable to utilize those losses. The following table summarizes changes in the valuation allowances. in millions Balance at Beginning of Period Deductions Acquisition (1) Additions Balance at End of Period Fiscal 2023 $ 763 (57) — $ 5 $ 711 Fiscal 2022 821 (74) — 16 763 Fiscal 2021 755 (12) 64 14 821 _________________________ (1) Related to the acquisition of Aleris. During fiscal 2023, after considering all available evidence, we released a full valuation allowance on temporary items and tax attributes of legacy Aleris US entities in certain separate filer states and unitary filer states that require combined or separate reporting, resulting in an income tax benefit of $10 million. Positive evidence included a recent history of three-year cumulative earnings as of March 31, 2023, and forecasted taxable earnings based on operations. We also released a full valuation allowance on temporary items and tax attributes of Aleris Aluminum (Zhenjiang) Co. Ltd. based on current results and the expectation of future profitability, resulting in an income tax benefit of $29 million. During fiscal 2022, after considering all available evidence, we released a portion of the Canadian valuation allowance, resulting in an income tax benefit of $73 million. It is reasonably possible that our estimates of future taxable income may change within the next 12 months, resulting in a change to the valuation allowance in one or more jurisdictions. As of March 31, 2023, we had net operating loss carryforwards of approximately $772 million (tax effected) and tax credit carryforwards of $152 million, which will be available to offset future taxable income and tax liabilities. The carryforwards began expiring in fiscal 2023. As of March 31, 2023, valuation allowances of $511 million, $113 million and $87 million had been recorded against net operating loss carryforwards, tax credit carryforwards, and other deferred tax assets, respectively, where it appeared more likely than not that such benefits will not be realized. The net operating loss carryforwards are predominantly in Canada, the U.S., Germany, China, and Italy. As of March 31, 2022, we had net operating loss carryforwards of approximately $846 million (tax effected) and tax credit carryforwards of $152 million, which will be available to offset future taxable income and tax liabilities. The carryforwards began expiring in fiscal 2022, with some amounts being carried forward indefinitely. As of March 31, 2022, valuation allowances of $538 million, $123 million, and $102 million had been recorded against net operating loss carryforwards, tax credit carryforwards, and other deferred tax assets, respectively, where it appeared more likely than not that such benefits will not be realized. The net operating loss carryforwards are predominantly in Canada, the U.S., Germany, China, and Italy. Although realization is not assured, management believes it is more likely than not that all the remaining net deferred tax assets will be realized. In the near term, the amount of deferred tax assets considered realizable could be reduced if we do not generate sufficient taxable income in certain jurisdictions. As of March 31, 2023, we had cumulative earnings of approximately $4 billion for which we had not provided Canadian income tax or withholding taxes because we consider them to be indefinitely reinvested. We acknowledge that we would need to accrue and pay taxes should we decide to repatriate cash and short-term investments generated from earnings of our foreign subsidiaries that are considered indefinitely reinvested. Except for those jurisdictions where we have already distributed and paid taxes on the earnings, we have reinvested and expect to continue to reinvest undistributed earnings of foreign subsidiaries indefinitely. Cash and cash equivalents held by foreign subsidiaries that are indefinitely reinvested are used to cover expansion and short-term cash flow needs of such subsidiaries. The amounts considered indefinitely reinvested would be subject to possible Canadian taxation only if remitted as dividends. However, due to our valuation allowance position of $517 million in Canada, in excess of $443 million of net operating loss carryforwards, exempt surpluses for Canadian tax purposes, $34 million of tax credits, and other deferred tax assets of $84 million, a portion of the cumulative earnings would not be taxed if distributed. Due to the complex structure of our international holdings and the various methods available for repatriation, quantification of the deferred tax liability, if any, associated with these undistributed earnings is not practicable. Tax Uncertainties As of March 31, 2023, and 2022, the total amount of unrecognized benefits that, if recognized, would affect the effective income tax rate in future periods based on anticipated settlement dates is $73 million and $71 million, respectively. Tax authorities continue to examine certain other of our tax filings for the fiscal year ended March 31, 2005, and the fiscal years ended March 31, 2013, through March 31, 2019. Our reserves for unrecognized tax benefits, as well as reserves for interest and penalties, are expected to decrease in the next 12 months as a result of further settlement of audits, judicial decisions, the filing of amended tax returns, or the expiration of statutes of limitations. With few exceptions, tax returns for all jurisdictions for all tax years before 2005 are no longer subject to examination by taxing authorities. Our policy is to record interest and penalties related to unrecognized tax benefits in income tax (benefit) provision on our consolidated statements of operations. As of March 31, 2023, 2022, and 2021, we accrued for interest and penalties of $9 million, $10 million, and $11 million, respectively. During fiscal 2022 and fiscal 2021, we recognized tax benefit of $2 million and tax expense of $2 million related to changes in accrued interest and penalties, respectively. During fiscal 2023, we had no tax expense or benefit related to changes in accrued interest and penalties. The main driver of the benefit realized in fiscal 2022 was the reduction in interest rate for uncertain tax positions in Germany as provided under proposed legislation. The following table summarizes the changes in unrecognized tax benefits. in millions Fiscal 2023 Fiscal 2022 Fiscal 2021 Beginning balance of unrecognized tax benefits $ 71 $ 69 $ 27 Additions based on tax positions related to the current period 7 5 4 Additions based on tax positions of prior years (1) 28 2 39 Reductions based on tax positions of prior years (2) (32) (1) (1) Settlements — — (1) Foreign exchange (1) (4) 1 Ending Balance of unrecognized tax benefits $ 73 $ 71 $ 69 _________________________ (1) Additions based on tax positions of prior years in fiscal 2021 includes $37 million from the acquisition of Aleris. Additions based on tax positions of prior years in fiscal year 2023 includes $19 million for Novelis Germany. (2) Reductions based on tax positions of prior years in fiscal 2023 includes $24 million for positions of Aleris Germany for years prior to the acquisition of Aleris. Income Taxes Payable Our accompanying consolidated balance sheets include income taxes payable, net of $108 million and $101 million as of March 31, 2023, and 2022, respectively.

Commitments and Contingencies Disclosure [Abstract] | |
22. COMMITMENTS AND CONTINGENCIES | 22. COMMITMENTS AND CONTINGENCIES We are party to, and may in the future be involved in or subject to, disputes, claims, and proceedings arising in the ordinary course of our business, including some we assert against others, such as environmental, health and safety, product liability, employee, tax, personal injury, and other matters. For certain matters in which the Company is involved for which a loss is reasonably possible, we are unable to estimate a loss. For certain other matters for which a loss is reasonably possible and the loss is estimable, we have estimated the aggregated range of loss as $0 to $69 million. This estimated aggregate range of reasonably possible losses is based upon currently available information. The Company's estimates involve significant judgment, and therefore, the estimate will change from time to time and actual losses may differ from the current estimate. We review the status of, and estimated liability related to, pending claims and civil actions on a quarterly basis. The evaluation model includes all asserted and unasserted claims that can be reasonably identified, including claims relating to our responsibility for compliance with environmental, health and safety laws and regulations in the jurisdictions in which we operate or formerly operated. The estimated costs in respect of such reported liabilities are not offset by amounts related to insurance or indemnification arrangements unless otherwise noted. Environmental Matters We own and operate numerous manufacturing and other facilities in various countries around the world. Our operations are subject to environmental laws and regulations from various jurisdictions, which govern, among other things, air emissions; wastewater discharges; the handling, storage and disposal of hazardous substances and wastes; the remediation of contaminated sites and restoration of natural resources; carbon and other greenhouse gas emissions; and employee health and safety. Future environmental, health and safety regulations may impose stricter compliance requirements on the industries in which we operate. Additional equipment or process changes at some of our facilities, and related capital expenditures, which may be material, may be needed to meet existing or future requirements. The cost of meeting these requirements may be significant. Failure to comply with such laws and regulations could subject us to administrative, civil, or criminal penalties; obligations to pay damages or other costs; and injunctions and other orders, including orders to cease operations. We are involved in proceedings under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act, also known as CERCLA or Superfund, or analogous state provisions regarding our liability arising from the usage, storage, treatment, or disposal of hazardous substances and wastes at a number of sites in the U.S., as well as similar proceedings under the laws and regulations of the other jurisdictions in which we have operations, including Brazil, certain countries in the European Union, and South Korea. Many of these jurisdictions have laws that impose joint and several liability, without regard to fault or the legality of the original conduct, for the costs of environmental, health and safety remediation, natural resource damages, third-party claims, and other expenses. In addition, we are, from time to time, subject to environmental, health and safety reviews and investigations by relevant governmental authorities. We have established liabilities based on our estimates for currently anticipated costs associated with environmental matters. We estimate that the costs related to our environmental liabilities as of March 31, 2023, were $37 million, of which $19 million was related to undiscounted clean-up costs, $15 million was associated with an increase in environmental reserves, and $3 million was associated with restructuring actions. As of March 31, 2023, $19 million is included in accrued expenses and other current liabilities and the remainder is within other long–term liabilities in our accompanying consolidated balance sheets consolidated balance sheet Brazil Tax Litigation Under a federal tax dispute settlement program established by the Brazilian government, we have settled several disputes with Brazil's tax authorities regarding various forms of manufacturing taxes and social security contributions. In most cases, we are paying the settlement amounts over a period of 180 months, although in some cases we are paying the settlement amounts over a shorter period. Total settlement liabilities were $11 million and $18 million as of March 31, 2023, and March 31, 2022, respectively. As of March 31, 2023, $7 million is included in accrued expenses and other current liabilities and the remainder is within other long–term liabilities in our accompanying consolidated balance sheets. In addition to the disputes we have settled under the federal tax dispute settlement program, we are involved in several other unresolved tax and other legal claims in Brazil. Total liabilities for other disputes and claims were $37 million and $38 million as of March 31, 2023, and March 31, 2022, respectively. As of March 31, 2023, $2 million is included in accrued expenses and other current liabilities and the remainder is within other long–term liabilities in our accompanying consolidated balance sheets. Additionally, we have included in the range of reasonably possible losses disclosed above any unresolved tax disputes or other contingencies for which a loss is reasonably possible and estimable. The interest cost recorded on these settlement liabilities offset by interest earned on the cash deposits is reported in other expenses (income), net on the consolidated statements of operations. During fiscal 2021, fiscal 2020, and fiscal 2019, we received multiple favorable rulings from the Brazilian court that recognized the right to exclude certain taxes from the tax base used to calculate contributions to the social integration program and social security contributions on gross revenues, also known as PIS and COFINS. As a result of these cases, we have the right to apply for tax credits for the amounts overpaid during specified tax years. These credits and corresponding interest can be used to offset various Brazilian federal taxes in future years. The Brazilian Office of the Attorney General of the National Treasury sought clarification from the Brazilian Supreme Court of certain matters, including the calculation methodology (i.e. gross or net credit amount) and timing of these credits. Since the Brazilian Supreme Court had not yet confirmed the appropriate methodology when these favorable rulings were received, Novelis recorded this benefit in the corresponding periods based on the net credit amount. However, during the first quarter of fiscal 2022, the Brazilian Supreme Court ruled that the credit should be calculated using the gross methodology for lawsuits filed prior to March 2017. As such, Novelis recorded additional income of $76 million in other expenses (income), net, $48 million of which is principal and $29 million is interest, related to PIS and COFINS for the years 2009 to 2017, net of $1 million in litigation expense. During the third quarter of fiscal 2022, Novelis recorded $5 million of additional income in other expenses (income), net, $2 million of which is principal and $3 million of which is interest, related to PIS and COFINS for certain periods. This income is subject to income taxes and therefore, resulted in the recognition of income of $64 million within net income. The credit amounts, interest calculation, and supporting documentation are subject to further validation and scrutiny by tax authorities for five years after the credits are utilized. Thus, credits recognized may differ from these amounts. In order to qualify for these credits, the Company is required to compile and present verifiable support validating the credits. During fiscal 2022, Novelis applied for and received official authorization from The Special Department of Federal Revenue of Brazil ("Receita Federal") to use the PIS and COFINS credits related to certain periods. Novelis was able to utilize a majority of these credits to offset taxes to be paid in fiscal 2022 and anticipates utilizing the remaining credits in the first quarter of fiscal 2023. |

23. SEGMENT, GEOGRAPHICAL AREA, MAJOR CUSTOMER AND MAJOR SUPPLIER INFORMATION | 23. SEGMENT, GEOGRAPHICAL AREA, MAJOR CUSTOMER AND MAJOR SUPPLIER INFORMATION Segment Information Due in part to the regional nature of supply and demand of aluminum rolled products and to best serve our customers, we manage our activities based on geographical areas and are organized under four operating segments: North America, Europe, Asia, and South America. All of our segments manufacture aluminum sheet and light gauge products. We also manufacture aluminum plate products in Europe and Asia. The following is a description of our operating segments. North America. Headquartered in Atlanta, Georgia, this segment operates 17 plants, including seven with recycling operations, in two countries. Europe. Headquartered in Küsnacht, Switzerland, this segment operates 10 plants, including five with recycling operations, in four countries. Asia. Headquartered in Seoul, South Korea, this segment operates four plants, including two with recycling operations, in two countries. South America. Headquartered in São Paulo, Brazil, this segment operates two plants in Brazil, including one with recycling operations. Net sales and expenses are measured in accordance with the policies and procedures described in Note 1 – Business and Summary of Significant Accounting Policies . We measure the profitability and financial performance of our operating segments based on Adjusted EBITDA. Adjusted EBITDA provides a measure of our underlying segment results that is in line with our approach to risk management. We define Adjusted EBITDA as earnings before (a) depreciation and amortization; (b) interest expense and amortization of debt issuance costs; (c) interest income; (d) unrealized gains (losses) on change in fair value of derivative instruments, net, except for foreign currency remeasurement hedging activities, which are included in Adjusted EBITDA; (e) impairment of goodwill; (f) (gain) loss on extinguishment of debt, net; (g) noncontrolling interests' share; (h) adjustments to reconcile our proportional share of Adjusted EBITDA from non-consolidated affiliates to income as determined on the equity method of accounting; (i) restructuring and impairment, net; (j) gains or losses on disposals of property, plant and equipment and businesses, net; (k) other costs, net; (l) litigation settlement, net of insurance recoveries; (m) sale transaction fees; (n) income tax provision (benefit); (o) cumulative effect of accounting change, net of tax; (p) metal price lag; (q) business acquisition and other related costs; (r) purchase price accounting adjustments; (s) income (loss) from discontinued operations, net of tax; and (t) loss on sale of discontinued operations, net of tax. Prior to fiscal 2023, we also utilized the term Segment Income to refer to Adjusted EBITDA. Both terms have the same definition and there is no difference in the composition or calculation of Adjusted EBITDA for the periods presented and Segment Income previously reported. Under ASC 280, Segment Reporting ("ASC 280"), our measure of segment profitability and financial performance of our operating segments is Adjusted EBITDA, and when used in this context, Adjusted EBITDA is a financial measure prepared in accordance with US GAAP. The tables that follow show selected segment financial information. "Eliminations and Other" includes eliminations and functions that are managed directly from our corporate office that have not been allocated to our operating segments as well as the adjustments for proportional consolidation and eliminations of intersegment net sales. The financial information for our segments includes the results of our affiliates on a proportionately consolidated basis, which is consistent with the way we manage our business segments. In order to reconcile the financial information for the segments shown in the tables below to the relevant U.S. GAAP based measures, we must adjust proportional consolidation of each line item. The "Eliminations and Other" in net sales – third party includes the net sales attributable to our joint venture party, Tri-Arrows, for our Logan affiliate because we consolidate 100% of the Logan joint venture for U.S. GAAP reporting purposes, but we manage our Logan affiliate on a proportionately consolidated basis.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Consolidation Policy | Consolidation Policy Our consolidated financial statements have been prepared in accordance with U.S. GAAP and include the assets, liabilities, revenues, and expenses of all wholly owned subsidiaries, majority-owned subsidiaries over which we exercise control, and entities in which we have a controlling financial interest or are deemed to be the primary beneficiary. We eliminate intercompany accounts and transactions from our consolidated financial statements. We use the equity method to account for our investments in entities that we do not control but have the ability to exercise significant influence over operating and financial policies. Consolidated net income attributable to our common shareholder includes our share of net income (loss) of these entities. The difference between consolidation and the equity method impacts certain of our financial ratios because of the presentation of the detailed line items reported in the consolidated financial statements for consolidated entities, compared to a two-line presentation of investment in and advances to non–consolidated affiliates and equity in net income of non-consolidated affiliates. |
Use of Estimates and Assumptions | Use of Estimates and Assumptions The preparation of our consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting periods. The principal areas of judgment relate to (1) impairment of goodwill; (2) actuarial assumptions related to pension and other postretirement benefit plans; (3) tax uncertainties and valuation allowances; and (4) assessment of loss contingencies, including environmental and litigation liabilities. Future events and their effects cannot be predicted with certainty, and accordingly, our accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of our consolidated financial statements may change as new events occur, more experience is acquired, additional information is obtained, and our operating environment changes. We evaluate and update our assumptions and estimates on an ongoing basis and may employ outside experts to assist in our evaluations. Actual results could differ from the estimates we have used. For more information regarding our use of estimates in the determination of fair values of assets acquired and liabilities assumed in the acquisition of Aleris, see Note 2 – Business Combination . |
Risks and Uncertainties | Risks and Uncertainties We are exposed to a number of risks in the normal course of our business that could potentially affect our financial position, results of operations, and cash flows. Risks & Uncertainties resulting from Inflation, COVID-19, and Geopolitical Instability Fiscal 2023 was marked by global economic uncertainty, capital markets disruption, and supply chain interruptions, which have been impacted by inflationary cost pressures, ongoing recovery from the COVID-19 pandemic, and geopolitical instability due to the military conflict between Russia and Ukraine. We have experienced increased inflationary cost pressures in fiscal 2023 resulting from global supply chain disruptions impacting the availability and price of materials and services including energy, freight, coatings, and alloys, such as magnesium. Geopolitical instability exacerbated inflationary cost pressures, which are expected to continue for the foreseeable future. We have not experienced significant direct impacts from the Russia-Ukraine conflict, as we do not have operations nor significant sales in either Russia or Ukraine. However, we have experienced indirect impacts, as the conflict has driven up energy prices globally, beginning in the fourth quarter of fiscal 2022, and we expect these costs will remain elevated until energy prices stabilize. To date, our operations have not been materially impacted by labor shortages, and we remain able to procure the necessary raw materials, parts, and equipment due to our diverse, global supplier network. While much of our customer demand and shipments have recovered in the majority of our end markets from the impact of the COVID-19 pandemic, we cannot predict the overall extent of the impact of any resurgence of COVID-19, its variants or any future pandemic on our operating results, cash flows, liquidity, and financial condition, which will depend on certain developments, including the duration and spread of such outbreak and its impact on our customers, employees, suppliers, and other partners. We believe we are positioned to maintain production levels necessary to service our customers in the near term. However, we cannot predict how long energy and other operating input prices will remain inflated, supply chains will continue to experience disruptions, or potential future financial impacts. We have been able to mitigate a portion of the higher inflationary cost impact through a combination of hedging, passing through a portion of higher costs to customers, favorable pricing environments, and increased recycled inputs. There is no assurance that we will continue to be able to mitigate these higher costs in the future. The overall extent of the impact of these factors on our operating results, cash flows, liquidity, and financial condition will depend on certain developments, including the duration of the current inflationary environment, supply chain disruptions, end market demand, and the Russia-Ukraine conflict. Although we have made our best estimates based on the current information, the effects of these factors on our business may result in future changes to our estimates and assumptions based on their duration. Actual results could materially differ from the estimates and assumptions developed by management. If so, we may be subject to future impairment charges as well as changes to recorded reserves and valuations. Laws and regulations We operate in an industry that is subject to a broad range of environmental, health and safety laws and regulations in the jurisdictions in which we operate. These laws and regulations impose increasingly stringent environmental, health and safety protection standards and permitting requirements regarding, among other things, air emissions; wastewater discharges; the handling, storage, and disposal of hazardous substances and wastes; the remediation of contaminated sites and restoration of natural resources; carbon and other greenhouse gas emissions; and employee health and safety. Some environmental laws, such as the U.S. Comprehensive Environmental Response, Compensation, and Liability Act, also known as CERCLA or Superfund, and comparable state laws impose joint and several liability for the cost of environmental remediation, natural resource damages, third-party claims, and other expenses, without regard to the fault or the legality of the original conduct. The costs of complying with these laws and regulations, including participation in assessments and remediation of contaminated sites and installation of pollution control facilities, have been, and in the future could be, significant. In addition, these laws and regulations may also result in substantial environmental liabilities associated with divested assets, third-party locations, and past activities. In certain instances, these costs and liabilities, as well as related actions to be taken by us, could be accelerated or increased if we were to close, divest of, or change the principal use of certain facilities with respect to which we may have environmental liabilities or remediation obligations. Currently, we are involved in a number of compliance efforts, remediation activities, and legal proceedings concerning environmental matters, including certain activities and proceedings arising under U.S. Superfund and comparable laws in other jurisdictions where we have operations. We have established liabilities for environmental remediation where appropriate. However, the cost of addressing environmental matters (including the timing of any charges related thereto) cannot be predicted with certainty, and these liabilities may not ultimately be adequate, especially in light of potential changes in environmental conditions, changing interpretations of laws and regulations by regulators and courts, the discovery of previously unknown environmental conditions, the risk of governmental orders to carry out additional compliance on certain sites not initially included in remediation in progress, our potential liability to remediate sites for which provisions have not been previously established, and the adoption of more stringent environmental laws. Such future developments could result in increased environmental costs and liabilities and could require significant capital expenditures, any of which could have a material adverse effect on our financial position, results of operations, or cash flows. Furthermore, the failure to comply with our obligations under applicable environmental, health and safety laws and regulations could subject us to administrative, civil, or criminal penalties, obligations to pay damages or other costs, and injunctions or other orders, including orders to cease operations. In addition, the presence of environmental contamination at our properties could adversely affect our ability to sell a property, receive full value for a property, or use a property as collateral for a loan. Some of our current and potential operations are located or could be located in or near communities that may regard such operations as having a detrimental effect on their social and economic circumstances. Environmental laws typically provide for participation in permitting decisions, site remediation decisions and other matters. Concern about environmental justice issues may affect our operations. Should such community objections be presented to government officials, the consequences of such a development may have a material adverse impact upon the profitability or, in extreme cases, the viability of an operation. In addition, such developments may adversely affect our ability to expand or enter into new operations in such location or elsewhere and may also have an effect on the cost of our environmental remediation projects. We use a variety of hazardous materials and chemicals in our rolling processes and in connection with maintenance work on our manufacturing facilities. Because of the nature of these substances or related residues, we may be liable for certain costs, including, among others, costs for health-related claims or removal or re-treatment of such substances. Certain of our current and former facilities incorporated asbestos-containing materials, a hazardous substance that has been the subject of health-related claims for occupation exposure. In addition, although we have developed environmental, health and safety programs for our employees, including measures to reduce employee exposure to hazardous substances, and conduct regular assessments at our facilities, we are currently, and in the future may be, involved in claims and litigation filed on behalf of persons alleging injury predominantly as a result of occupational exposure to substances at our current or former facilities. It is not possible to predict the ultimate outcome of these claims and lawsuits due to the unpredictable nature of personal injury litigation. If these claims and lawsuits, individually or in the aggregate, were finally resolved against us, our financial position, results of operations, and cash flows could be adversely affected. Materials and labor In the aluminum rolled products industry, our raw materials are subject to continuous price volatility. We may not be able to pass on the entire cost of the increases to our customers or offset fully the effects of higher raw material costs through productivity improvements, which may cause our profitability to decline. In addition, there is a potential time lag between changes in prices under our purchase contracts and the point when we can implement a corresponding change under our sales contracts with our customers. As a result, we could be exposed to fluctuations in raw materials prices which could have a material adverse effect on our financial position, results of operations, and cash flows. Significant price increases may result in our customers substituting other materials, such as plastic or glass, for aluminum or switching to another aluminum rolled products producer, which could have a material adverse effect on our financial position, results of operations, and cash flows. We consume substantial amounts of energy in our rolling operations and our cast house operations. The factors that affect our energy costs and supply reliability tend to be specific to each of our facilities. A number of factors could materially adversely affect our energy position including, but not limited to increases in the cost of natural gas; increases in the cost of supplied electricity or fuel oil related to transportation; interruptions in energy supply due to equipment failure or other causes; and the inability to extend energy supply contracts upon expiration on favorable terms. A significant increase in energy costs or disruption of energy supplies or supply arrangements could have a material adverse effect on our financial position, results of operations, and cash flows. A substantial portion of our employees are represented by labor unions under a large number of collective bargaining agreements with varying durations and expiration dates. Although we have not experienced a material impact to our operations from a strike or work stoppage in recent years, we may not be successful in preventing such an event from occurring in the future at one or more of our manufacturing facilities. In addition, we may not be able to satisfactorily renegotiate our collective bargaining agreements when they expire. Any work stoppages or material changes in the terms of our labor agreements could have an adverse impact on our financial condition. Geographic markets We are, and will continue to be, subject to financial, political, economic, and business risks in connection with our global operations. We have made investments and carry on production activities in various emerging markets, including China, Brazil, and South Korea, and we market our products in these countries, as well as certain other countries in Asia, Africa, and the Middle East. While we anticipate higher growth or attractive production opportunities from these emerging markets, they also present a higher degree of risk than more developed markets. In addition to the business risks inherent in developing and servicing new markets, economic conditions may be more volatile, legal and regulatory systems may be less developed and predictable, and the possibility of various types of adverse governmental action may be more pronounced. In addition, inflation, fluctuations in currency and interest rates, competitive factors, civil unrest, and labor problems could affect our revenues, expenses, and results of operations. Our operations could also be adversely affected by acts of war (including the Russia-Ukraine conflict), terrorism, or the threat of any of these events as well as government actions such as controls on imports, exports and prices, tariffs, new forms of taxation, changes in fiscal regimes, and increased government regulation in the countries in which we operate or service customers. Unexpected or uncontrollable events or circumstances in any of these markets could have a material adverse effect on our financial position, results of operations, and cash flows. Other risks and uncertainties In addition, refer to Note 17 – Financial Instruments and Commodity Contracts , Note 19 – Fair Value Measurements , and Note 22 – Commitments and Contingencies for a discussion of financial instruments and commitments and contingencies. |
Revenue Recognition | Net Sales We recognize revenue in accordance with ASC 606, Revenue from Contracts with Customers. The Company's contracts with customers consist of purchase orders with standard terms and conditions. These contracts typically consist of the manufacture of products, which represent single performance obligations that are satisfied upon transfer of control of the product to the customer at a point in time. Transfer of control is assessed based on alternative use of the products we produce and our enforceable right to payment for performance to date under the contract terms. Transfer of control and revenue recognition generally occur upon shipment or delivery of the product, which is when title, ownership, and risk of loss pass to the customer and is based on the applicable shipping terms. The shipping terms vary across all businesses and depend on the product, the country of origin, and the type of transportation (truck, train, or vessel). The length of payment terms can vary per contract, but none extend beyond one year. Revenue is recognized net of any volume rebates or other incentives. Occasionally we receive advance payments to secure product to be delivered in future periods. These advance payments are recorded as deferred revenue, and revenue is recognized as our performance obligations are satisfied throughout the term of the applicable contract. Certain of our contracts contain take-or-pay clauses which allow us to recover an agreed upon penalty if a buyer does not purchase contractual minimums as defined in the underlying contract within a set timeframe, which is generally within one year. Additionally, certain of our contracts may contain incentive payments to our customers that are deferred and amortized as a reduction to the amount of revenue recorded on a straight-line basis over the term of these contracts. During fiscal 2023 and fiscal 2021, we recognized $37 million and $38 million, respectively, in net sales associated with these customer contractual obligations. During fiscal 2022, amounts recognized in net sales associated with these customer contractual obligations were not material. We disaggregate revenue from contracts with customers on a geographic basis. This disaggregation also achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of net sales and cash flows are affected by economic factors. We manage our activities on the basis of geographical regions and are organized under four operating segments: North America, South America, Asia, and Europe. See Note 23 – Segment, Geographical Area, Major Customer and Major Supplier Information |
Cost of Goods Sold (Exclusive of Depreciation and Amortization) | Cost of Goods Sold (Exclusive of Depreciation and Amortization) Cost of goods sold (exclusive of depreciation and amortization) includes all costs associated with inventories, including the procurement of materials, the costs to convert such materials into finished products, and the costs of warehousing and distributing finished goods to customers. Material procurement costs include inbound freight charges as well as purchasing, receiving, inspection, and storage costs. Conversion costs include the costs of direct production inputs such as labor and energy, as well as allocated overheads from indirect production centers and plant administrative support areas. Warehousing and distribution costs include inside and outside storage costs, outbound freight charges, and the costs of internal transfers. |
Selling, General and Administrative Expenses | Selling, General and Administrative Expenses Selling, general and administrative expenses include selling, marketing, and advertising expenses; salaries, travel, and office expenses of administrative employees and contractors; legal and professional fees; software license fees; the provision for credit losses; and factoring expenses. |
Research and Development | Research and Development Expenses We incur costs in connection with R&D programs that are expected to contribute to future earnings and charge such costs against income as incurred. Research and development expenses consist primarily of salaries and administrative costs. |
Restructuring Activities | Restructuring Activities Restructuring charges, which are recorded within restructuring and impairment, net on our consolidated statements of operations, include employee severance and benefit costs, impairments of certain assets, and other costs associated with exit activities. Restructuring costs are determined based on estimates, which are prepared at the time the restructuring actions were approved by management and are periodically reviewed and updated for changes in estimates. We apply the provisions of ASC 420, Exit or Disposal Cost Obligations ("ASC 420") and ASC 712, Compensation — Nonretirement Postemployment Benefits ("ASC 712" ). Severance and benefit costs related to restructuring activities are accounted for under ASC 420 and/or ASC 712 and are recognized when management with the proper level of authority has committed to a restructuring plan and communicated those actions to employees. Impairment losses are based upon the estimated fair value less costs to sell, with fair value estimated based on existing market prices for similar assets. Other exit costs include environmental remediation costs and contract termination costs, primarily related to equipment and facility lease obligations. At each reporting date, we evaluate the accruals for restructuring costs to ensure the accruals are still appropriate. See Note 4 – Restructuring and Impairment for further discussion. |
Business Acquisition and Other Integration Related Costs | Business Acquisition and Other Related Costs Business acquisition and other related costs includes costs associated with the acquisition of Aleris, including legal and professional fees associated with the transaction. See Note 2 – Business Combination for further details about the transaction. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents includes investments that are highly liquid and have maturities of three months or less when purchased. The carrying values of cash and cash equivalents approximate their fair value due to the short-term nature of these instruments. We maintain amounts on deposit with various financial institutions, which may at times exceed federally insured limits. However, management periodically evaluates the creditworthiness of those institutions, and we have not experienced any losses on such deposits. Restricted Cash Restricted cash primarily relates to cash deposits for employee benefits and is disclosed on the consolidated statement of cash flows. Restricted cash is included in prepaid expenses and other current assets and other long–term assets on the consolidated balance sheets. |
Accounts Receivable | Accounts Receivable, Net Our accounts receivable are geographically dispersed. We do not obtain collateral relating to our accounts receivable. We do not believe there are any significant concentrations of revenues from any particular customer or group of customers that would subject us to any significant credit risks in the collection of our accounts receivable. We report accounts receivable at the estimated net realizable amount we expect to collect from our customers. Additions to the allowance for credit losses are made by means of the provision for credit losses. We write-off uncollectible accounts receivable against the allowance for credit losses after exhausting collection efforts. For each of the periods presented, we performed an analysis of our historical cash collection patterns and considered the impact of any known material events in determining the allowance for credit losses. See Note 5 – Accounts Receivable for further information. Inventories We carry our inventories at the lower of their cost or net realizable value, reduced by obsolete and excess inventory. We use the average cost method to determine cost. Included in inventories are stores inventories, which are carried at average cost. See Note 6 – Inventories for further discussion. |
Derivative Instruments | Derivative Instruments We hold derivatives for risk management purposes rather than for trading. We use derivatives to mitigate uncertainty and volatility caused by underlying exposures to metal prices, foreign exchange rates, and energy prices. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date and are reported gross. We may be exposed to losses in the future if counterparties to our derivative contracts fail to perform. We are satisfied that the risk of such non-performance is remote due to our monitoring of credit exposures. Additionally, we enter into master netting agreements with contractual provisions that allow for netting of counterparty positions in case of default, and we do not face credit contingent provisions that would result in the posting of collateral. In accordance with ASC 815, Derivatives and Hedging, for cash flow hedges we recognize and defer the entire periodic change in the fair value of the hedging instrument in other comprehensive income (loss). The amounts recorded in other comprehensive income (loss) are subsequently reclassified to earnings in the same line item impacted by the hedged item when the hedged item affects earnings. For derivatives designated as cash flow hedges or net investment hedges, we assess hedge effectiveness by formally evaluating the high correlation of the expected future cash flows of the hedged item and the derivative hedging instrument. The entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is included in other comprehensive income (loss) and reclassified to earnings in the period in which earnings are impacted by the hedged items or in the period that the transaction becomes probable of not occurring. Gains or losses representing reclassifications of other comprehensive income (loss) to earnings are recognized in the same line item that is impacted by the underlying exposure. We exclude the time value component of foreign currency and aluminum price risk hedges when measuring and assessing effectiveness to align our accounting policy with risk management objectives when it is necessary. If at any time during the life of a cash flow hedge relationship we determine that the relationship is no longer effective, the derivative will no longer be designated as a cash flow hedge and future gains or losses on the derivative will be recognized in other expenses (income), net. For derivatives designated as fair value hedges, we assess hedge effectiveness by formally evaluating the high correlation of changes in the fair value of the hedged item and the derivative hedging instrument. The changes in the fair values of the underlying hedged items are reported in prepaid expenses and other current assets, other long–term assets, accrued expenses and other current liabilities, and other long–term liabilities in the consolidated balance sheets. Changes in the fair values of these derivatives and underlying hedged items generally offset, and the entire change in the fair value of derivatives is recorded in the consolidated statement of operations line item consistent with the underlying hedged item. If no hedging relationship is designated, gains or losses are recognized in other expenses (income), net in our consolidated statements of operations. Consistent with the cash flows from the underlying risk exposure, we classify cash settlement amounts associated with designated derivatives as part of either operating or investing activities in the consolidated statements of cash flows. If no hedging relationship is designated, we classify cash settlement amounts as part of investing activities in the consolidated statement of cash flows. The majority of our derivative contracts are valued using industry-standard models that use observable market inputs as their basis, such as time value, forward interest rates, volatility factors, and current ("spot") and forward market prices for commodity and foreign exchange rates. See Note 17 – Financial Instruments and Commodity Contracts and Note 19 – Fair Value Measurements for additional discussion related to derivative instruments. |
Property, Plant and Equipment | Property, Plant and Equipment We record land, buildings, leasehold improvements, and machinery and equipment at cost. We record assets under finance lease obligations at the lower of their fair value or the present value of the aggregate future minimum lease payments as of the beginning of the lease term. We generally depreciate our assets using the straight-line method over the shorter of the estimated useful life of the assets or the lease term, excluding any lease renewals, unless the lease renewals are reasonably certain. See Note 7 – Property, Plant and Equipment for further discussion. We assign useful lives to and depreciate major components of our property, plant and equipment. The ranges of estimated useful lives follow. Range in Years Buildings 30 to 40 Leasehold improvements 7 to 20 Machinery and equipment 2 to 25 Furniture, fixtures and equipment 3 to 10 Equipment under finance lease obligations 5 to 15 Most of our large scale machinery, including hot mills, cold mills, continuous casting mills, furnaces, and finishing mills have useful lives of 15 to 25 years. Supporting machinery and equipment, including automation and work rolls, have useful lives of 2 to 15 years. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life of an asset. We also capitalize construction costs and interest incurred while major construction and development projects are in progress. These amounts are capitalized as construction in progress within property, plant and equipment until the asset is placed into service. Once placed into service, the asset, including the associated capitalized interest, is reclassified from construction in progress to the appropriate property, plant and equipment component and depreciation commences. We retain fully depreciated assets in property and accumulated depreciation accounts until they are removed from service. In the case of sale, retirement, or disposal, the asset cost and related accumulated depreciation balances are removed from the respective accounts, and the resulting net amount, after consideration of any proceeds, is included as a gain or loss in other expenses (income), net or gain on assets held for sale in our consolidated statements of operations. We account for operating leases under the provisions of ASC 842, Leases . This pronouncement requires us to recognize escalating rents, including any rent holidays, on a straight-line basis over the term of the lease for those lease agreements where we receive the right to control the use of the entire leased property at the beginning of the lease term. |
Goodwill | Goodwill We test for impairment at least annually as of the last day of each fiscal year, unless a triggering event occurs that would require an interim impairment assessment. We do not aggregate components of operating segments to arrive at our reporting units and, as such, our reporting units are the same as our operating segments. In performing our goodwill impairment test, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the estimated fair value of a reporting unit is less than its carrying amount. If we perform a qualitative assessment and determine that an impairment is more likely than not, then we perform the one-step quantitative impairment test, otherwise no further analysis is required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the one-step quantitative impairment test. The ultimate outcome of the goodwill impairment assessment will be the same whether we choose to perform the qualitative assessment or proceed directly to the one-step quantitative impairment test. No goodwill impairment was identified for fiscal 2023, fiscal 2022, or fiscal 2021. See Note 8 – Goodwill and Intangible Assets for further discussion. We use the present value of estimated future cash flows to establish the estimated fair value of our reporting units as of the testing date. This approach includes many assumptions related to long-term growth rate, discount factors, and tax rates, among other considerations. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairment in future periods. Additionally, we use the market approach to corroborate the estimated fair value. If the carrying amount of a reporting unit's goodwill exceeds its estimated fair value, we would recognize an impairment charge in an amount equal to that excess in our consolidated statements of operations. During our analysis for fiscal 2023, fiscal 2022, and fiscal 2021, the estimated fair value of each of our reporting units exceeded the carrying amount of the reporting unit's goodwill. When a business within a reporting unit is disposed of, goodwill is allocated to the gain or loss on disposition using the relative fair value methodology. |
Long-Lived Assets and Other Intangible Assets | Long-Lived Assets and Other Intangible Assets We amortize the cost of intangible assets over their respective estimated useful lives to their estimated residual value. See Note 8 – Goodwill and Intangible Assets for further discussion. We assess the recoverability of long-lived assets (excluding goodwill) and finite-lived intangible assets, whenever events or changes in circumstances indicate that we may not be able to recover the asset's carrying amount. We measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset (groups) to the expected, undiscounted future net cash flows to be generated by that asset (groups), or, for identifiable intangible assets, by determining whether the amortization of the intangible asset balance over its remaining life can be recovered through undiscounted future cash flows. The amount of impairment of identifiable intangible assets is based on the present value of estimated future cash flows. We measure the amount of impairment of other long-lived assets and intangible assets (excluding goodwill) as the amount by which the carrying value of the asset exceeds the fair value of the asset, which is generally determined as the present value of estimated future cash flows or as the appraised value. Impairments of long-lived assets and intangible assets are included in restructuring and impairment, net in the consolidated statement of operations. See Note 4 – Restructuring and Impairment for further discussions. |
Assets and Liabilities Held for Sale | Assets and Liabilities Held for Sale We classify long-lived assets (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the asset (disposal group); the asset (disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (disposal groups); an active program to locate a buyer and other actions required to complete the plan to sell the asset (disposal group) have been initiated; the sale of the asset (disposal group) is probable, and transfer of the asset (disposal group) is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset (disposal group) beyond one year; the asset (disposal group) is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We initially measure a long-lived asset (disposal group) that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset (disposal group) until the date of sale. We assess the fair value of a long-lived asset (disposal group) less any costs to sell each reporting period it remains classified as held for sale and report any reduction in fair value as an adjustment to the carrying value of the asset (disposal group). Upon being classified as held for sale we cease depreciation. We continue to depreciate long-lived assets to be disposed of other than by sale. |
Investments in and Advances to Non-Consolidated Affiliates | Investment in and Advances to Non-Consolidated Affiliates We assess the potential for other-than-temporary impairment of our equity method investments when impairment indicators are identified. We consider all available information, including the recoverability of the investment, the earnings and near-term prospects of the affiliate, factors related to the industry, conditions of the affiliate, and our ability, if any, to influence the management of the affiliate. We assess fair value based on valuation methodologies, as appropriate, including the present value of estimated future cash flows, estimates of sales proceeds, and external appraisals. If an investment is considered to be impaired and the decline in value is other than temporary, we record an appropriate write-down. See Note 10 – Investment in and Advances to Non-Consolidated Affiliates and Related Party Transactions for further discussion. |
Financing Costs | Financing Costs We amortize financing costs and premiums, and accrete discounts, over the remaining life of the related debt using the effective interest amortization method, unless the impact of utilizing the straight-line method results in an immaterial difference. The expense is included in interest expense and amortization of debt issuance costs in our consolidated statements of operations. We record discounts and unamortized financing costs as a direct deduction from, or premiums as a direct addition to, the face amount of the financing. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments ASC 820, Fair Value Measurements and Disclosures ("ASC 820"), defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 also applies to measurements under other accounting pronouncements, such as ASC 825, Financial Instruments ("ASC 825") that require or permit fair value measurements. ASC 825 requires disclosures of the fair value of financial instruments. Our financial instruments include: cash and cash equivalents; certificates of deposit; accounts receivable; accounts payable; foreign currency, energy derivative instruments; cross-currency swaps; metal option and forward contracts; share-based compensation; related party notes receivables and payables; letters of credit; short-term borrowings; and long-term debt. The carrying amounts of cash and cash equivalents, certificates of deposit, accounts receivable, accounts payable and current related party notes receivable and payable approximate their fair value because of the short-term maturity and highly liquid nature of these instruments. The fair value of our letters of credit is deemed to be the amount of payment guaranteed on our behalf by third-party financial institutions. We determine the fair value of our short-term borrowings and long-term debt based on various factors including maturity schedules, call features and current market rates. We also use quoted market prices, when available, or the present value of estimated future cash flows to determine fair value of our share-based compensation liabilities, short-term borrowings and long-term debt. When quoted market prices are not available for various types of financial instruments (such as currency, energy and interest rate derivative instruments, swaps, options, and forward contracts), we use standard pricing models with market-based inputs, which take into account the present value of estimated future cash flows. See Note 19 – Fair Value Measurements for further discussion. |
Pension and Postretirement Benefits | Pensions and Postretirement Benefits Our pension obligations relate to funded defined benefit pension plans in the U.S., Canada, Switzerland, and the U.K.; unfunded pension plans in the U.S., Canada, and Germany; unfunded lump sum indemnities in France and Italy; and partially funded lump sum indemnities in South Korea. Our other postretirement obligations include unfunded health care and life insurance benefits provided to retired employees in Canada, the U.S., and Brazil. We account for our pensions and other postretirement benefits in accordance with ASC 715, Compensation — Retirement Benefits ("ASC 715"). We recognize the funded status of our benefit plans as a net asset or liability, with an offsetting adjustment to accumulated other comprehensive loss in shareholder's equity. The funded status is calculated as the difference between the fair value of plan assets and the benefit obligation. For fiscal 2023 and fiscal 2022, we used March 31 as the measurement date. We use standard actuarial methods and assumptions to account for our pension and other postretirement benefit plans. Pension and postretirement benefit obligations are actuarially calculated using management's best estimates of the rate used to discount the future estimated liability, the long-term rate of return on plan assets, and several assumptions related to the employee workforce (compensation increases, health care cost trend rates, expected service period, retirement age, and mortality). Pension and postretirement benefit expense includes the actuarially computed cost of benefits earned during the current service period, the interest cost on accrued obligations, the expected return on plan assets based on fair market value and the straight-line amortization of net actuarial gains and losses and adjustments due to plan amendments, curtailments, and settlements. Net actuarial gains and losses are amortized over periods of 15 years or less, which represent the group's average future service life of the employees or the group's average life expectancy. See Note 15 – Postretirement Benefit Plans for further discussion. |
Noncontrolling Interests in Consolidated Affiliates | Noncontrolling Interests in Consolidated Affiliates These financial statements reflect the application of ASC 810, Consolidations, which establishes accounting and reporting standards that require: (i) the ownership interest in subsidiaries held by parties other than the parent to be clearly identified and presented in the consolidated balance sheet within shareholder's (deficit) equity, but separate from the parent's (deficit) equity; (ii) the amount of consolidated net income attributable to the parent and the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations and (iii) changes in a parent's ownership interest while the parent retains its controlling financial interest in its subsidiary to be accounted for consistently. Our consolidated financial statements include all assets, liabilities, revenues, and expenses of less-than-100%-owned affiliates that we control or for which we are the primary beneficiary. We record a noncontrolling interest for the allocable portion of income or loss and comprehensive income or loss to which the noncontrolling interest holders are entitled based upon their ownership share of the affiliate. Distributions made to the holders of noncontrolling interests are charged to the respective noncontrolling interest balance. |
Environmental Liabilities | Environmental Liabilities We record accruals for environmental matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. We adjust these accruals periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are stated at undiscounted amounts. Environmental liabilities are included in our consolidated balance sheets in accrued expenses and other current liabilities and other long–term liabilities, depending on their short- or long-term nature. Any receivables for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in prepaid expenses and other current assets on our consolidated balance sheets. Costs related to environmental matters are charged to expense. Estimated future incremental operations, maintenance, and management costs directly related to remediation are accrued in the period in which such costs are determined to be probable and estimable. See Note 22 – Commitments and Contingencies |
Litigation Contingencies | Litigation Contingencies We accrue for loss contingencies associated with outstanding litigation, claims, and assessments for which management has determined it is probable that a loss contingency exists and the amount of loss can be reasonably estimated. We expense professional fees associated with litigation claims and assessments as incurred. See Note 22 – Commitments and Contingencies for further discussion. |
Income Taxes | Income Taxes We account for income taxes using the asset and liability method. This approach recognizes the amount of income taxes payable or refundable for the current year, as well as deferred tax assets and liabilities for the future tax consequence of events recognized in the consolidated financial statements and income tax returns. Deferred income tax assets and liabilities are adjusted to recognize the effects of changes in tax laws or enacted tax rates. Under ASC 740, Income Taxes ("ASC 740"), a valuation allowance is required when it is more likely than not that some portion of the deferred tax assets will not be realized. Realization is dependent on generating sufficient taxable income through various sources. We record tax benefits related to uncertain tax positions taken or expected to be taken on a tax return when such benefits meet a more than likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, the statute of limitation has expired or the appropriate taxing authority has completed their examination. Interest and penalties related to uncertain tax positions are recognized as part of the provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized. See Note 21 – Income Taxes for further discussion. |
Share-Based Compensation | Share-Based Compensation In accordance with ASC 718, Compensation — Stock Compensation ("ASC 718"), we recognize compensation expense for a share-based award over an employee's requisite service period based on the award's grant date fair value, subject to adjustment. Our share-based awards are settled in cash and are accounted for as liability-based awards. As such, liabilities for awards under these plans are required to be measured at fair value at each reporting date until the date of settlement. See Note 14 – Share-Based Compensation for further discussion. |
Foreign Currency Translation | Foreign Currency Translation The assets and liabilities of foreign operations, whose functional currency is other than the U.S. dollar (located in Europe and Asia), are translated to U.S. dollars at the period end exchange rates, and revenues and expenses are translated at average exchange rates for the period. Differences arising from this translation are included in the currency translation adjustment component of accumulated other comprehensive loss and noncontrolling interests, both of which are on our consolidated balance sheets. If there is a planned or completed sale or liquidation of our ownership in a foreign operation, the relevant currency translation adjustment is recognized in our consolidated statement of operations. For all operations, the monetary items denominated in currencies other than the functional currency are remeasured at period-end exchange rates, and transaction gains and losses are included in other expenses (income), net in our consolidated statements of operations. Non-monetary items are remeasured at historical rates. |
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards We did not adopt any new accounting pronouncements during fiscal 2023, fiscal 2022, or fiscal 2021 that had a material impact on our consolidated financial condition, results of operations, or cash flows.

Schedule of Business Acquisitions, by Acquisition | The final calculation of merger consideration paid to Aleris follows. in millions Amount Cash for equity consideration (1) $ 711 Repayment of Aleris' debt (including prepayment penalties and accrued interest) (2) 1,954 Earn-out consideration (3) 50 Payment associated with Duffel capital expenditures (4) 60 Fair value of merger consideration $ 2,775 _________________________ (1) Under the terms of the Merger Agreement, this represents the cash consideration, which is the base consideration for the settlement of all shares of common stock outstanding, including shares issued in connection with the conversion of the 6% Senior Subordinated Exchangeable Notes due 2020 issued by Aleris International, Inc. into Aleris common shares, and the settlement of stock options and restricted stock units, less transaction costs of $64 million. The transaction costs are removed from the base consideration as these costs were incurred by Aleris prior to the closing date and were not reimbursed by Novelis. Additionally, under the terms of the Merger Agreement, there is a €8 million (approximately $9 million at the date of acquisition) German tax indemnification included in the cash for equity consideration that will be payable to the selling shareholders upon the condition that the existing Aleris German tax receivable is received from the German tax authorities. During the third quarter of fiscal 2021, Novelis settled this payable with the selling shareholders. (2) On the closing date, all of the outstanding historical debt of Aleris, except for certain non-recourse multi-currency secured term loan facilities (collectively, the "Zhenjiang Term Loans"), was repaid in connection with the merger. In addition, prepayment penalties and accrued interest of approximately $12 million and $16 million, respectively, associated with the Aleris debt were paid in connection with such repayment. (3) Under the terms of the Merger Agreement, this represents the fair value of the earn-out consideration which was based upon Aleris meeting specified commercial margin targets. On the closing date, Aleris had met all of the specified targets in the Merger Agreement and the selling shareholders received the $50 million cash payment. (4) In connection with obtaining the regulatory antitrust approvals, the European Commission required Novelis to pay the buyer of Duffel an additional €55 million (approximately $60 million at the date of acquisition) to fund capital expenditures that would be required so that Duffel can operate as a standalone business. This amount was paid on September 30, 2020 and is included in acquisition of business and other investments, net of cash and restricted cash acquired in the consolidated statement of cash flows for fiscal 2021. The preliminary allocation of purchase price recorded for Aleris as of June 30, 2020 and subsequently revised for measurement period adjustments follows. in millions Assets Acquired as of June 30, 2020 (1) Measurement Period Adjustments Assets Acquired as of March 31, 2021 (1) Cash and cash equivalents $ 105 $ — $ 105 Accounts receivable (2) 251 17 268 Inventories 379 — 379 Prepaid expenses and other current assets (3) 24 — 24 Fair value of derivative instruments 46 — 46 Current assets of discontinued operations (4) 463 1 464 Property, plant and equipment (5) 949 (5) 944 Goodwill (6)(7)(8)(9) 328 141 469 Intangible assets, net (5)(6) 149 318 467 Deferred income tax assets (7) 114 (20) 94 Other long-term assets 39 — 39 Long–term assets of discontinued operations (8) 944 (390) 554 Total assets $ 3,791 $ 62 $ 3,853 Liabilities Assumed as of June 30, 2020 (1) Measurement Period Adjustments Liabilities Assumed as of March 31, 2021 (1) Current portion of long–term debt $ 24 $ — $ 24 Accounts Payable (2) 141 17 158 Fair value of derivative instruments 25 — 25 Accrued expenses and other current liabilities 143 — 143 Current liabilities of discontinued operations 166 — 166 Long–term debt, net of current portion 125 — 125 Deferred income tax liabilities (7) 37 4 41 Accrued postretirement benefits 164 — 164 Other long–term liabilities (9) 41 41 82 Long–term liabilities of discontinued operations 150 — 150 Total liabilities $ 1,016 $ 62 $ 1,078 Net assets acquired $ 2,775 Total purchase price $ 2,775 _________________________ (1) In connection with the acquisition of Aleris, the Company acquired two businesses which were required to be sold. Therefore, such businesses were classified as held for sale and were included within the current assets of discontinued operations, long-term assets of discontinued operations, current liabilities of discontinued operations, and long–term liabilities of discontinued operations line items in the above allocation of purchase price (see Note 3 – Discontinued Operations ). As of March 31, 2021, both of these businesses were sold and are no longer included in the consolidated balance sheets of Novelis. (2) The measurement period adjustment related to the presentational alignment of pending derivative settlements on a gross basis in accordance with Novelis' policy during the second quarter of fiscal 2021. (3) Included in prepaid expenses and other current assets is $9 million of restricted cash acquired related to cash deposits restricted for the payment of the Zhenjiang Term Loans. (4) Included in current assets of discontinued operations is $41 million of cash and cash equivalents acquired related to our discontinued operations. (5) The measurement period adjustment of $5 million related to presentational alignment of certain capitalized software in accordance with Novelis' policy during the third quarter of fiscal 2021. (6) The measurement period adjustment related to revisions in the valuation of intangible assets based on refinements to key assumptions, such as discount rates and growth rates, of $261 million and $52 million during the second and third quarters of fiscal 2021, respectively. (7) The measurement period adjustment related to deferred tax impacts of the measurement period adjustments and other tax adjustments, resulting in a decrease in deferred tax assets of $34 million during the second quarter, an increase of $22 million during the third quarter, and a decrease of $8 million during the fourth quarter of fiscal 2021, respectively. Deferred tax liabilities were adjusted by $4 million in the fourth quarter of fiscal 2021. (8) The measurement period adjustment related to estimated costs to sell the Duffel and Lewisport businesses, in addition to revisions to key assumptions of the valuation of Lewisport and Duffel's property, plant and equipment, of $284 million and $75 million during the second and third quarters of fiscal 2021, respectively, and revisions to key assumptions related to Lewisport's intangible assets of $31 million during the second quarter of fiscal 2021. (9) The measurement period adjustment related to certain uncertain tax positions and customs related adjustments identified during the third quarter of fiscal 2021. |
