Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation and Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and balances have been eliminated. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Business Combinations: The Company uses the acquisition method of accounting, which requires separate recognition of assets acquired and liabilities assumed from goodwill, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the fair value of any non-controlling interests in the acquiree over the net of the acquisition date fair values of the assets acquired and liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company has the ability to record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated statement of income. Discontinued Operations Presentation: The consolidated financial statements and related notes reflect the three plants in Europe acquired as part of the Bemis acquisition as a discontinued operation in fiscal 2019 as the Company agreed to divest of these plants as a condition of approval from the European Commission. See Note 5, "Discontinued Operations," for more information on discontinued operations. The plants were divested in the first quarter of fiscal 2020. Estimates and Assumptions Required: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates are based on historical experience and various assumptions believed to be reasonable under the circumstances. Management evaluates these estimates on an ongoing basis and adjusts or revises the estimates as circumstances change. As future events and their impacts cannot be determined with precision, actual results may differ from these estimates. In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the results of the periods presented. The impact that the 2019 Novel Coronavirus ("COVID-19") pandemic will have on the Company's consolidated operations is uncertain. The Company has considered the potential impacts of the COVID-19 pandemic when developing the Company's estimates and judgements as of June 30, 2020, and will continue to evaluate the extent of the impact on the Company's business and consolidated financial statements. The Company's accounting estimates and assumptions may change over time in response to COVID-19 and the change could be material in future periods. Translation of Foreign Currencies: The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s subsidiaries is generally the local currency of such entity. Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the entity’s functional currency are remeasured at the exchange rate as of the balance sheet date to the entity’s functional currency. Foreign currency transaction gains and losses related to short-term and long-term debt are recorded in other non-operating income (loss), net, in the consolidated statement of income. The Company recorded such foreign currency transaction net loss of $0.4 million, net gain of $1.1 million and net loss of $82.7 million during the fiscal years ended June 30, 2020, 2019 and 2018, respectively. All other foreign currency transaction gains and losses are recorded in other income, net in the consolidated statement of income. These foreign currency transaction net gains amounted to $21.4 million, $8.9 million and $1.0 million during the fiscal years ended June 30, 2020, 2019 and 2018, respectively. Upon consolidation, the results of operations of subsidiaries whose functional currency is other than the reporting currency of the Company are translated using average exchange rates in effect during each year. Assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at the exchange rate as of the balance sheet date, while equity balances are translated at historical rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Highly Inflationary Accounting: A highly inflationary economy is defined as an economy with a cumulative inflation rate of approximately 100 percent or more over a three-year period. If a country's economy is classified as highly inflationary, the financial statements of the foreign entity operating in that country must be remeasured to the functional currency of the parent. As of July 1, 2018, the Argentine economy was designated as highly inflationary for accounting purposes. Accordingly, the U.S. dollar replaced the Argentine peso as the functional currency for the Company's subsidiaries in Argentina. The impact of highly inflationary accounting was $27.7 million and $30.2 million for the fiscal years ended June 30, 2020 and 2019, respectively, in the consolidated statement of income. Revenue Recognition: The Company generates revenue by providing its customers with flexible and rigid packaging serving a variety of markets including food, consumer products and healthcare end markets. The Company enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the terms under which the Company does business with a specific customer. The Company also sells to some customers solely based on purchase orders. The Company has concluded for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. All revenue recognized in the consolidated statement of income is considered to be revenue from contracts with customers. The Company typically satisfies the obligation to provide packaging to customers at a point in time upon shipment when control is transferred to customers. Revenue is recognized net of allowances for returns and customer claims and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company does not have any material contract assets or contract liabilities. The Company disaggregates revenue based on geography. Disaggregation of revenue is presented in Note 20, "Segments". Significant Judgments Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company identified potential performance obligations in its customer master supply agreements and determined that none of them are capable of being distinct as the customer can only benefit from the supplied packaging. Therefore, the Company has concluded that it has one performance obligation to supply packaging to customers. The Company may provide variable consideration in several forms which are determined through its agreements with customers. The Company can offer prompt payment discounts, sales rebates or other incentive payments to customers. Sales rebates and other incentive payments are typically awarded upon achievement of certain performance metrics, including volume. The Company accounts for variable consideration using the most likely amount method. The Company utilizes forecasted sales data and rebate percentages specific to each customer agreement and updates its judgment of the amounts to which the customer is entitled each period. The Company enters into long term agreements with certain customers, under which it is obligated to make various up-front payments for which it expects to receive a benefit in excess of the cost over the term of the contract. These up-front payments are deferred and reflected in prepaid expenses and other current assets or other non-current assets on its consolidated balance sheet. Contract incentives are typically recognized as a reduction to revenue over the term of the customer agreement. Practical Expedients The Company sells primarily through its direct sales force. Any external sales commissions are expensed when incurred because the amortization period would be one year or less. External sales commission expense is included in selling, general and administrative expense in the consolidated statement of income. The Company accounts for shipping and handling activities as fulfillment costs. Accordingly, shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers are classified as a component of net sales. The Company excluded from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected from the customer, including sales taxes, value added taxes, excise taxes and use taxes. Accordingly, the tax amounts are not included in net sales. The Company does not adjust the promised consideration for the time value of money for contracts where the difference between the time of payment and performance is one year or less. Research and Development: Research and development expenditures are expensed as incurred. Restructuring Costs: Restructuring costs are recognized when the liability is incurred. The Company calculates severance obligations based on its standard customary practices. Accordingly, the Company records provisions for severance when probable and estimable and the Company has committed to the restructuring plan. In the absence of a standard customary practice or established local practice, liabilities for severance are recognized when incurred. If fixed assets are to be disposed of as a result of the Company’s restructuring efforts, the assets are written off when the Company commits to dispose of them and they are no longer in use. Depreciation is accelerated on fixed assets for the period of time the asset continues to be used until the asset ceases to be used. Other restructuring costs, including costs to relocate equipment, are generally recorded as the cost is incurred or the service is provided. See Note 6, "Restructuring Plans," for more information on the Company’s restructuring plans. Cash and Cash Equivalents: The Company considers all highly liquid temporary investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents include certificates of deposit that can be readily liquidated without penalty at the Company’s option. Cash equivalents are carried at cost which approximates fair market value. Trade Receivables, Net: Trade accounts receivable, net, are stated at the amount the Company expects to collect, which is net of an allowance for sales returns and the estimated losses resulting from the inability of its customers to make required payments. When determining the collectability of specific customer accounts, a number of factors are evaluated, including: customer creditworthiness, past transaction history with the customer and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. The Company has an allowance for doubtful accounts of $35.3 million and $34.4 million recorded at June 30, 2020 and 2019, respectively, in trade receivables, net, on the consolidated balance sheet. The current year expense to adjust the allowance for doubtful accounts is recorded within selling, general and administrative expenses in the consolidated statement of income. The Company enters into factoring arrangements from time to time to sell trade receivables to third-party financial institutions. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are reflected as a reduction of trade receivables, net on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. Agreements that allow the Company to maintain effective control over the transferred receivables and which do not qualify as a true sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within trade receivables, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statement of income primarily as a reduction of net sales. Factored receivables not qualifying as a true sale were accounted for as secured borrowings. As of June 30, 2020 and 2019, amounts factored recorded under trade receivables, net and short-term debt, were zero and $152.7 million, respectively. Inventories: Inventories are valued primarily at the lower of cost, as determined by the first-in, first-out ("FIFO") method, or net realizable value. Inventory values using the FIFO method of accounting approximate replacement cost. Inventories are summarized at June 30, 2020 and 2019 as follows: (in millions) 2020 2019 Raw materials and supplies $ 808.6 $ 864.6 Work in process and finished goods 1,127.6 1,180.9 Less: inventory reserves (104.3) (91.7) Inventory, net $ 1,831.9 $ 1,953.8 Property, Plant and Equipment, Net: Property, plant and equipment ("PP&E"), net is carried at cost less accumulated depreciation and impairment and includes expenditures for new facilities and equipment and those costs which substantially increase the useful lives or capacity of existing PP&E. Cost of constructed assets includes capitalized interest incurred during the construction period. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. PP&E, including assets held under finance leases, is depreciated using the straight-line method over the estimated useful lives of assets or, in the case of leasehold improvements and leased assets, over the period of the lease or useful life of the asset, whichever is shorter, as described below. The Company periodically reviews these estimated useful lives and, when appropriate, changes are made prospectively. Leasehold land Over lease term Land improvements Up to 30 years Buildings Up to 45 years Plant and equipment Up to 25 years Finance leases Shorter of lease term or 5 - 25 years For tax purposes, the Company generally uses accelerated methods of depreciation. The tax effect of the difference between book and tax depreciation has been provided for as deferred income taxes. Impairment of Long-lived Assets: The Company reviews long-lived assets, primarily PP&E and certain identifiable intangible assets with finite lives, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows or external appraisals, as applicable. Impairment losses recognized in the consolidated statement of income were as follows: Years ended June 30, (in millions) 2020 2019 2018 Selling, general and administrative ("SG&A") expenses $ 0.7 $ 47.7 $ 0.4 Restructuring and related expenses 20.8 27.4 4.0 Total impairment losses recognized in the consolidated statement of income $ 21.5 $ 75.1 $ 4.4 Leasing: The Company has operating leases for certain manufacturing sites, office space, warehouses, land, vehicles and equipment. Right-of-use lease assets and lease liabilities are recognized at the commencement date based on the present value of the remaining lease payments over the lease term, which includes renewal periods the Company is reasonably certain to exercise. The Company reevaluates its leases on a regular basis to consider the economic and strategic incentives of exercising lease renewal options. Short term leases with a term of twelve months or less, including reasonably certain holding periods, are not recorded on the consolidated balance sheet. As the Company's leases generally do not provide an implicit rate, the Company uses its incremental borrowing rate as of the commencement date to determine the present value of lease payments. The Company recognizes expense for operating leases on a straight-line basis over the lease term in the consolidated statement of income. Certain leasing arrangements require variable payments that are dependent on usage or output or may vary for other reasons. Variable lease payments that do not depend on an index or rate are excluded from lease payments in the measurement of the right-of-use asset and lease liability and recognized as expense in the period in which the obligation for the payments occur. Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but instead tested annually or whenever events and circumstances indicate an impairment may have occurred during the year. Among the factors that could trigger an impairment review are a reporting unit’s operating results significantly declining relative to its operating plan or historical performance, and competitive pressures and changes in the general markets in which it operates. In light of the COVID-19 pandemic and related global impacts, the Company considered the potential for goodwill impairment of its reporting units in the third fiscal quarter of 2020. The review did not indicate an impairment triggering event as of March 31, 2020. All goodwill is assigned to a reporting unit, which is defined as the operating segment. In conjunction with the acquisition of Bemis, the Company reassessed its segment reporting structure in the first fiscal quarter of 2020 and elected to disaggregate the Flexibles Americas operating segment into Flexibles North America and Flexibles Latin America. With this change, the Company has six reporting units with goodwill that are assessed for potential impairment. In performing the required impairment tests, the Company has the option to first assess qualitative factors to determine if it is necessary to perform a quantitative assessment for goodwill impairment. If the qualitative assessment concludes that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. The Company's quantitative assessment utilizes present value (discounted cash flow) methods to determine the fair value of the reporting units with goodwill. Determining fair value using discounted cash flows requires considerable judgment and is sensitive to changes in underlying assumptions and market factors. Key assumptions relate to revenue growth, projected operating income growth, terminal values, and discount rates. If current expectations of future growth rates and margins are not met, or if market factors outside of Amcor’s control, such as factors impacting the applicable discount rate, or economic or political conditions in key markets, change significantly, then goodwill allocated to one or more reporting units may be impaired. The Company performs its annual impairment analysis in the fourth quarter of each year. A quantitative impairment analysis was performed in the fourth fiscal quarter for all reporting units for the fiscal years ended 2020 and 2018, while a qualitative analysis was performed for the fiscal year ended 2019. The Company’s annual impairment analysis for all three fiscal years concluded that goodwill was not impaired. The Company’s quantitative goodwill analysis in fiscal years 2020 and 2018 concluded that the fair values substantially exceeded the carrying amounts for each reporting unit. Although no reporting units failed the assessments noted above in the annual impairment analysis for 2020, during the time subsequent to the annual evaluation, and at June 30, 2020, the Company considered whether any events and/or changes in circumstances, including the impact of the COVID-19 pandemic, had resulted in the likelihood that the goodwill of any of its reporting units may have been impaired. It is management's opinion that no such events have occurred. Other Intangible Assets, Net: Contractual or separable intangible assets that have finite useful lives are amortized against income using the straight-line method over their estimated useful lives, with original periods ranging from one Costs incurred to develop software programs to be used solely to meet the Company's internal needs have been capitalized as computer software within other intangible assets. Fair Value Measurements: The fair values of the Company's financial assets and financial liabilities reflect the amounts that would be received to sell the assets or paid to transfer the liabilities in an orderly transaction between market participants at the measurement date (exit price). The Company determines fair value based on a three-tiered fair value hierarchy. The hierarchy consists of: • Level 1: fair value measurements represent exchange-traded securities which are valued at quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date; • Level 2: fair value measurements are determined using input prices that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data; and • Level 3: fair value measurements are determined using unobservable inputs, such as internally developed pricing models for the asset or liability due to little or no market activity for the asset or liability. Financial Instruments: The Company recognizes all derivative instruments on the consolidated balance sheet at fair value. The impact on earnings from recognizing the fair values of these instruments depends on their intended use, their hedge designation and their effectiveness in offsetting changes in the fair values of the exposures they are hedging. Derivatives not designated as hedging instruments are adjusted to fair value through income. Depending on the nature of derivatives designated as hedging instruments, changes in the fair value are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized. Gains or losses, if any, related to the ineffective portion of any hedge are recognized through earnings over the life of the hedging relationship. See Note 11, "Derivative Instruments," for more information regarding specific derivative instruments included on the Company’s consolidated balance sheet, such as forward foreign currency exchange contracts, currency swap contracts, and interest rate swap arrangements, among other derivative instruments. Employee Benefit Plans: The Company sponsors various defined contribution plans to which it makes contributions on behalf of employees. The expense under such plans was $63.5 million, $39.9 million and $39.8 million for the fiscal years ended June 30, 2020, 2019 and 2018, respectively. The Company sponsors a number of defined benefit plans that provide benefits to current and former employees. For the company-sponsored plans, the relevant accounting guidance requires that management make certain assumptions relating to the long-term rate of return on plan assets, discount rates used to determine the present value of future obligations and expenses, salary inflation rates, mortality rates and other assumptions. The Company believes that the accounting estimates related to its pension plans are critical accounting estimates because they are highly susceptible to change from period to period based on the performance of plan assets, actuarial valuations, market conditions and contracted benefit changes. The selection of assumptions is based on historical trends and known economic and market conditions at the time of valuation, as well as independent studies of trends performed by the Company’s actuaries. However, actual results may differ substantially from the estimates that were based on the critical assumptions. The Company recognizes the funded status of each defined benefit pension plan in the consolidated balance sheet. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability. Pension plan liabilities are revalued annually, or when an event occurs that requires remeasurement, based on updated assumptions and information about the individuals covered by the plan. Accumulated actuarial gains and losses in excess of a 10 percent corridor and the prior service cost are amortized on a straight-line basis from the date recognized over the average remaining service period of active participants or over the average life expectancy for plans with significant inactive participants. The service costs related to defined benefits are included in operating income. The other components of net benefit cost other than service cost are recorded within other non-operating income (loss), net in the consolidated statement of income Equity Method Investments: Investments in ordinary shares of companies, in which the Company believes it exercises significant influence over operating and financial policies, are accounted for using the equity method of accounting. Under this method, the investment is carried at cost and is adjusted to recognize the investor’s share of earnings or losses of the investee after the date of acquisition and is adjusted for impairment whenever it is determined that a decline in the fair value below the cost basis is other than temporary. The fair value of the investment then becomes the new cost basis of the investment and it is not adjusted for subsequent recoveries in fair value. Impairment losses have been recognized for the Company's equity investment in AMVIG Holdings Limited ("AMVIG") in the last three fiscal years. See Note 7, "Equity Method Investments," for more information regarding the Company's equity method investments. Share-based Compensation: Amcor has a variety of equity incentive plans. For employee awards with a service or market condition, compensation expense is recognized over the vesting period on a straight-line basis using the grant date fair value of the award and the estimated number of awards that are expected to vest. For awards with a performance condition, the Company must reassess the probability of vesting at each reporting period and adjust compensation cost based on its probability assessment. The Company also has cash-settled share-based compensation plans which are accounted for as liabilities. Such share-based awards are remeasured to fair value at each reporting period. The Company estimates forfeitures based on employee level, economic conditions, time remaining to vest and historical forfeiture experience. Income Taxes: The Company uses the asset and liability method to account for income taxes. Deferred income taxes reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based upon enacted income tax laws and tax rates. Income tax expense or benefit is provided based on earnings reported in the consolidated financial statements. The provision for income tax expense or benefit differs from the amounts of income taxes currently payable because certain items of income and expense included in the consolidated financial statements are recognized in different time periods by taxing authorities. Deferred tax assets, including operating loss, capital loss and tax credit carryforwards, are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that any portion of these tax attributes will not be realized. In addition, from time to time, management must assess the need to accrue or disclose uncertain tax positions for proposed adjustments from various tax authorities who regularly audit the Company in the normal course of business. In making these assessments, management must often analyze complex tax laws of multiple jurisdictions. Accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company records the related interest expense and penalties, if any, as tax expense in the tax provision. See Note 16, "Income Taxes," for more information on the Company's income taxes.

New Accounting Guidance

New Accounting Guidance	12 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
New Accounting Guidance	New Accounting Guidance Recently Adopted Accounting Standards In March 2020, the SEC issued Final Rule Release No. 33-10762, " Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant's Securities " that simplifies the disclosure requirements related to registered securities under Rule 3-10 of Regulation S-X. The rule replaces the requirement to provide condensed consolidating financial information with a requirement to present summarized financial information of the issuers and guarantors in either a note to the financial statements or in management's discussion and analysis. The effective date of the amendment is January 4, 2021 with earlier voluntary compliance permitted. The Company elected to adopt the amended rules effective with our third fiscal quarter of 2020 and has included the required disclosures as a component of "Part II, Item 7. - Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Annual Report on Form 10-K. In February 2018, the Financial Accounting Standards Board ("FASB") issued guidance that requires the Company to disclose a description of the Company’s accounting policy for releasing income tax effects from accumulated other comprehensive income and whether the Company elects to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act ("The Act"), along with information about other income tax effects that are reclassified. For all entities, the guidance was effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Entities can choose whether to apply the amendments retrospectively to each period in which the effect of the Act is recognized or to apply the amendments in the period of adoption. This guidance was effective for the Company on July 1, 2019. The Company adopted the new guidance effective July 1, 2019 and did not elect the optional reclassification as the impact was not material. In August 2017, the FASB issued guidance which simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. For public business entities, the amendments in Accounting Standards Update ("ASU") 2017-12 were effective for financial statements issued for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. This guidance was effective for the Company on July 1, 2019 using the modified retrospective approach, with the exception of presentation and disclosure guidance which is adopted prospectively. Implementation of the standard did not have a material impact on the Company's condensed consolidated financial statements. In February 2016, the FASB issued guidance that required lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to past accounting guidance. The guidance also eliminates the previous real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs and lease executory costs for all entities. Lease classification will determine how to recognize lease-related revenue and expense. The Company adopted the new lease standard at July 1, 2019 using a simplified transition option that allows for a cumulative-effect adjustment in the period of adoption and therefore did not restate prior periods. The Company also elected to adopt the package of practical expedients which allows for existing operating leases to continue to be classified as operating leases under the new guidance without reassessing whether the contracts contain a lease under the new guidance or whether classification of the operating lease would be different under the new standard. The Company did not elect the use-of-hindsight practical expedient but did adopt the practical expedient pertaining to land easements which provides the option not to reassess whether land easements not previously accounted for as leases under prior leasing guidance would be leases under the new guidance. Adoption of the new leasing standard resulted in the following impacts to the Company's condensed consolidated financial statements as of the adoption date: the establishment of a lease liability of $590.5 million, including current portion, a corresponding right-of-use asset of $569.8 million, and the reclassification of approximately $58.2 million (net of tax) of deferred gains on sale leaseback transactions. The complete impact of the changes made to the Company's condensed consolidated balance sheet due to the adoption of the new leasing guidance were as follows: ($ in millions) June 30, 2019 Adjustments due to Adoption At July 1, 2019 Operating lease assets — 569.8 569.8 Other current liabilities 1,044.9 54.3 1,099.2 Operating lease liabilities — 506.8 506.8 Deferred tax liabilities 1,011.7 18.7 1,030.4 Other non-current liabilities 241.0 (68.2) 172.8 Retained earnings 323.7 58.2 381.9 Due to the adoption of the guidance using the simplified transition option, there are no changes to the Company's previously reported results prior to July 1, 2019. Lease expense is not expected to change materially as a result of adoption of the new guidance. The Company changed its disclosures related to leasing beginning in fiscal year 2020. Refer to Note 14, "Leases". Accounting Standards Not Yet Adopted In June 2016, the FASB issued guidance which requires financial assets, or a group of financial assets measured at amortized cost basis to be presented at the net amount expected to be collected when finalized. The allowance for credit losses is a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. This guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance will be effective for the Company on July 1, 2020 and will be adopted using the modified retrospective approach. The Company does not expect the standard to have a material impact on its consolidated financial statements. In December 2019, the FASB issued updated guidance to simplify the accounting for income taxes by removing certain exceptions and improving the consistent application of U.S. GAAP in other tax accounting areas. This guidance is effective for annual reporting periods, and any interim periods within those annual periods, that begin after December 15, 2020 with early adoption permitted. Accordingly, the guidance will be effective for the Company on July 1, 2021. The Company is currently evaluating the impact that this guidance will have on its financial statements and related disclosures. In March 2020, the FASB issued optional expedients and exceptions to ease the potential burden in accounting for reference rate reform related to contract modifications, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued, subject to meeting certain criteria. The Company is currently evaluating whether to elect the adoption of this optional guidance. The Company considers the applicability and impact of all ASUs issued by the FASB and SEC. The Company determined that all other ASUs not yet adopted to be either not applicable or are expected to have minimal impact on the Company's consolidated financial statements at this time.

Business Combinations [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures Year ended June 30, 2019 Bemis Company, Inc. On June 11, 2019, the Company completed the acquisition of 100% of the outstanding shares of Bemis Company, Inc ("Bemis"), a global manufacturer of flexible packaging products based in the United States. Pursuant to the Transaction Agreement, dated as of August 6, 2018, each outstanding share of Bemis common stock that was issued and outstanding upon completion of the transaction was converted into the right to receive 5.1 ordinary shares of the Company traded on the New York Stock Exchange ("NYSE"). The following table summarizes the fair value of consideration exchanged: Bemis shares outstanding at June 11, 2019 (in millions) 91.7 Share Exchange Ratio 5.1 Price per Share (Based on Amcor’s closing share price on June 11, 2019) $ 11.18 Total Equity Consideration $ 5,229.6 The acquisition of Bemis positioned the Company as a global leader in consumer packaging with a comprehensive global footprint in flexible packaging and greater scale in key regions of North America, Latin America, Asia Pacific and Europe, along with industry-leading research and development capabilities. The acquisition of Bemis was accounted for as a business combination in accordance with ASC 805, "Business Combinations," which required allocation of the purchase price to the estimated fair values of assets acquired and liabilities assumed in the transaction. The fair value of the assets acquired and liabilities assumed as of the acquisition date were finalized upon completion of the measurement period in the fourth fiscal quarter of 2020. The allocation was subject to change within the measurement period, up to one year from the acquisition date, as additional information concerning final asset and liability valuations was obtained. The measurement period adjustments resulted in a $229.9 million increase to goodwill, which includes a $210.6 million decrease to property, plant and equipment, a $99.0 million decrease to finite lived intangible assets, a $184.1 million decrease to deferred tax liabilities, a $97.9 million increase in other non-current liabilities, along with other adjustments to assets held for sale and working capital. The following table summarizes the final allocation of the total purchase consideration to the fair values of the assets acquired and liabilities assumed at the acquisition date. (in millions) Cash and cash equivalents $ 3.3 Trade receivables 425.6 Inventories 665.4 Prepaid expenses and other current assets 80.5 Assets held for sale 464.2 Property, plant and equipment 1,180.1 Deferred tax assets 42.8 Other intangible assets 1,931.2 Other non-current assets 52.8 Total identifiable assets acquired 4,845.9 Current portion of long-term debt 1.7 Short-term debt 8.6 Trade payables 286.2 Accrued employee costs 188.1 Other current liabilities 314.1 Liabilities held for sale 21.9 Long-term debt, less current portion 1,365.3 Deferred tax liabilities 598.5 Employee benefit obligation 62.7 Other non-current liabilities 136.8 Total liabilities assumed 2,983.9 Net identifiable assets acquired 1,862.0 Goodwill 3,367.6 Net assets acquired $ 5,229.6 The following table details the identifiable intangible assets acquired from Bemis, their fair values and estimated useful lives: Fair Value Weighted-average Estimated Useful Life (in millions) (Years) Customer relationships $ 1,650.0 15 Technology 110.0 7 Other 171.2 7 Total other intangible assets $ 1,931.2 The allocation of the purchase price resulted in $3,367.6 million of goodwill for the Flexibles Segment, which is not tax deductible. The goodwill on acquisition represents the future economic benefit expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. The fair value measurement of tangible and intangible assets and liabilities was based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value measurement hierarchy. Level 3 fair market values were determined using a variety of information, including estimated future cash flows, appraisals and market comparables. Divestitures Closing of the Bemis acquisition was conditional upon the receipt of regulatory approvals, approval by both Amcor and Bemis shareholders, and satisfaction of other customary conditions. In order to satisfy certain regulatory approvals, the Company was required to divest three of Bemis' medical packaging facilities located in the United Kingdom and Ireland ("EC Remedy") and three Amcor medical packaging facilities in the United States ("U.S. Remedy"). The U.S. Remedy was completed during the fourth quarter of fiscal 2019 and the Company received $214.2 million resulting in a gain of $159.1 million. The EC Remedy was completed during the first quarter of fiscal 2020 and the Company received $397.1 million and recorded a loss on the sale of $8.8 million which is the result of the reclassification of accumulated foreign currency translation amounts from accumulated other comprehensive income to earnings from discontinued operations upon sale of the EC Remedy. In addition, the Company sold an equity method investment acquired through the Bemis acquisition in the third quarter of fiscal 2020 for proceeds of $27.7 million. There was no gain on sale as the investment was recorded at fair value upon acquisition. Unaudited Pro Forma Information The following unaudited pro forma information has been prepared as if the acquisition of Bemis and the sale of the EC Remedy and U.S. Remedy had occurred as of July 1, 2017. The unaudited pro forma information combines the historical results of Amcor and Bemis. Years ended June 30, (in millions) 2019 2018 Net sales $ 12,972.4 $ 13,146.3 Income from continuing operations $ 565.5 $ 535.0 Pro forma adjustments to net sales are as follows: • excludes net sales of the EC Remedy and U.S. Remedy. Pro forma adjustments to income from continuing operations attributable to Amcor plc are as follows: • excludes income from the EC Remedy which has been accounted for as a discontinued operation and the U.S. Remedy which has been reported in U.S. GAAP income from continuing operations; • excludes acquisition related charges; • includes acquisition accounting adjustments, including amortization and depreciation adjustments as a result of the fair value adjustment to property, plant and equipment; and • excludes the impact on net income attributable to purchase accounting related inventory effects and sales backlog amortization given these charges do not have a continuing impact on the consolidated results. The unaudited pro forma results are not necessarily indicative of the actual results that would have occurred had the acquisition been in effect for the periods presented, nor is it intended to be a projection of future results. For example, the unaudited pro forma results do not include the expected synergies from the transactions, nor the related costs to achieve.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On February 11, 2019, the Company received approval from the European Commission ("EC") for the acquisition of Bemis. A condition of the approval was an agreement to divest three Bemis medical packaging facilities located in the United Kingdom and Ireland ("EC Remedy"). Upon completion of the Bemis acquisition on June 11, 2019, the Company determined that the EC Remedy met the criteria to be classified as a discontinued operation, in accordance with ASC 205-20, "Discontinued Operations." The sale of the EC Remedy closed on August 8, 2019. The Company recorded a loss on the sale of $8.8 million, which is the result of the reclassification of accumulated foreign currency translation amounts from accumulated other comprehensive income to earnings from discontinued operations upon sale of the EC Remedy. The assets and liabilities of the EC Remedy, which is within the Company's Flexibles Segment, are reflected as held for sale in the consolidated balance sheet at June 30, 2019. Assets and liabilities classified as held for sale are required to be recorded at the lower of carrying value or fair value less costs to sell. The following table summarizes the results of the EC Remedy, classified as discontinued operations, from June 11, 2019 until the sale of the EC Remedy on August 8, 2019: Years ended June 30, (in millions) 2020 2019 Net sales $ 15.8 $ 9.6 Income (loss) from discontinued operations (7.1) 0.9 Tax expense on discontinued operations (0.6) (0.2) Income (loss) from discontinued operations, net of tax $ (7.7) $ 0.7

Restructuring Plans

Restructuring Plans	12 Months Ended

Restructuring and Related Activities [Abstract]
Restructuring Plans	Restructuring Plans 2019 Bemis Integration Plan In connection with the acquisition of Bemis, the Company initiated restructuring activities in the fourth quarter of 2019 aimed at integrating and optimizing the combined organization. As previously announced, the Company continues to target realizing approximately $180 million of pre-tax synergies driven by procurement, supply chain, and general and administrative savings by the end of fiscal year 2022. The Company's total 2019 Bemis Integration Plan pre-tax integration costs are expected to be approximately $200 million. The total 2019 Bemis Integration Plan costs include $165 million of restructuring and related expenses and $35 million of general integration expenses. The restructuring and related expenses are comprised of approximately $90 million in employee related expenses, $25 million in fixed asset related expenses, $20 million in other restructuring and $30 million in restructuring related expenses. The Company estimates that approximately $150 million of the $200 million total integration costs will result in cash expenditures, of which $115 million relate to restructuring and related expenditures. Cash payments for the fiscal year 2020 were $80.2 million, of which $54.1 million were payments related to restructuring and related expenditures. The 2019 Bemis Integration Plan relates to the Flexibles segment and Corporate and is expected to be completed by the end of fiscal year 2022. Restructuring related costs are directly attributable to restructuring activities; however, they do not qualify for special accounting treatment as exit or disposal activities. General integration costs are not linked to restructuring. The Company believes the disclosure of restructuring related costs provides more information on the total cost of our 2019 Bemis Integration Plan. The restructuring related costs relate primarily to the closure of facilities and include costs to replace graphics and train new employees on relocated equipment. 2018 Rigid Packaging Restructuring Plan On August 21, 2018, the Company announced a restructuring plan in Amcor Rigid Packaging ("2018 Rigid Packaging Restructuring Plan") aimed at reducing structural costs and optimizing the footprint. The Plan includes the closures of manufacturing facilities and headcount reductions to achieve manufacturing footprint optimization and productivity improvements as well as overhead cost reductions. The Company's total 2018 Rigid Packaging Restructuring Plan pre-tax restructuring costs are expected to be approximately $110 million with the main component being the cost to exit manufacturing facilities and employee related costs. The total plan cost has been increased by approximately $15 million in the fourth quarter of fiscal year 2020 due primarily to additional non-cash impairments. The Company estimates that approximately $65 to $70 million of the $110 million total costs will result in cash expenditures. Cash payments for the fiscal year 2020 were $23.6 million. The 2018 Rigid Packaging Restructuring Plan is expected to be completed during fiscal year 2021. 2016 Flexibles Restructuring Plan On June 9, 2016, the Company announced a major initiative ("2016 Flexibles Restructuring Plan") to optimize the cost base and drive earnings growth in the Flexibles segment. This initiative was designed to accelerate the pace of adapting the organization within developed markets through footprint optimization to better align capacity with demand, increase utilization and improve the cost base and streamlining the organization and reducing complexity, particularly in Europe, to enable greater customer focus and speed to market. As part of the 2016 Flexibles Restructuring Plan, the Company has closed eight manufacturing facilities and reduced headcount at certain facilities. The Company's total pre-tax restructuring costs were $230.8 million, with $166.7 million in employee termination costs, $31.4 million in fixed asset impairment costs and $32.7 million in other costs, which primarily represent the cost to dismantle equipment and terminate existing lease contracts. Approximately $166 million of the $230.8 million total costs resulted in cash expenditures. Cash payments for fiscal year 2019 were $14.4 million. The Plan was substantially completed by the end of fiscal year 2019. Other Restructuring Plans The Company entered into other individually immaterial restructuring plans ("Other Restructuring Plans"). The Company's restructuring charge related to these Plans was approximately $17.9 million, $18.8 million and $25.8 million for the years ended June 30, 2020, 2019 and 2018, respectively.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Equity Method Investments Investments accounted for under the equity method generally include all entities in which the Company or its subsidiaries have significant influence, with usually not more than 50% voting interest, and are recorded in the consolidated balance sheet in investments in affiliated companies. Investments in affiliated companies as of June 30, 2020 and 2019 include an interest in AMVIG Holdings Limited ("AMVIG") of 47.6% and other individually immaterial investments. AMVIG is listed on the Hong Kong Stock Exchange. Its quoted share price as of June 30, 2020 and 2019 was $0.18 (HKD 1.40) and $0.24 (HKD 1.85), respectively. The value of Amcor's investment in AMVIG based on its quoted share price as of June 30, 2020 and 2019 was $77.7 million and $104.8 million, respectively. During the years ended June 30, 2020, 2019 and 2018 the Company received dividends of $9.8 million, $8.2 million and $8.4 million, respectively, from AMVIG. The Company reviews its investment in affiliated companies for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Due to impairment indicators present in each of the years presented, the Company performed an impairment test by comparing the carrying value of its investment in AMVIG to its fair value, which was determined based on AMVIG's quoted share price. The fair value of the investment dropped below its carrying value during fiscal years 2020, 2019 and 2018, and therefore the Company recorded an other-than-temporary impairment of $25.6 million, $14.0 million and $36.5 million, respectively, to bring the value of its investment to fair value. The impairment charge was included in equity in income (loss) of affiliated companies, net of tax, in the consolidated statement of income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair values of the Company's financial assets and financial liabilities listed below reflect the amounts that would be received to sell the assets or paid to transfer the liabilities in an orderly transaction between market participants at the measurement date (exit price). The Company's non-derivative financial instruments primarily include cash and cash equivalents, trade receivables, trade payables, short-term debt and long-term debt. At June 30, 2020 and 2019, the carrying value of these financial instruments, excluding long-term debt, approximates fair value because of the short-term nature of these instruments. Fair value disclosures are classified based on the fair value hierarchy. See Note 2, "Significant Accounting Policies," for information about the Company's fair value hierarchy. The fair value of long-term debt with variable interest rates approximates its carrying value. The fair value of the Company's long-term debt with fixed interest rates is based on market prices, if available, or expected future cash flows discounted at the current interest rate for financial liabilities with similar risk profiles. The carrying values and estimated fair values of long-term debt with fixed interest rates (excluding finance leases) were as follows: June 30, 2020 June 30, 2019 Carrying Value Fair Value Carrying Value Fair Value (in millions) (Level 2) (Level 2) Total long-term debt with fixed interest rates (excluding commercial paper and finance leases) $ 3,599.3 $ 3,793.1 $ 2,955.6 $ 3,041.3 Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis Additionally, the Company measures and records certain assets and liabilities, including derivative instruments and contingent purchase consideration liabilities, at fair value. The following table summarizes the fair value of these instruments, which are measured at fair value on a recurring basis, by level, within the fair value hierarchy: June 30, 2020 (in millions) Level 1 Level 2 Level 3 Total Assets Commodity contracts $ — $ 0.4 $ — $ 0.4 Forward exchange contracts — 7.4 — 7.4 Interest rate swaps — 32.0 — 32.0 Total assets measured at fair value $ — $ 39.8 $ — $ 39.8 Liabilities Contingent purchase consideration liabilities $ — $ — $ 14.8 $ 14.8 Commodity contracts — 6.7 — 6.7 Forward exchange contracts — 16.8 — 16.8 Interest rate swaps — — — — Cross currency interest rate swaps — 0.2 — 0.2 Total liabilities measured at fair value $ — $ 23.7 $ 14.8 $ 38.5 June 30, 2019 (in millions) Level 1 Level 2 Level 3 Total Assets Commodity contracts $ — $ — $ — $ — Forward exchange contracts — 5.5 — 5.5 Interest rate swaps — 32.8 — 32.8 Total assets measured at fair value $ — $ 38.3 $ — $ 38.3 Liabilities Contingent purchase consideration liabilities $ — $ — $ 13.6 $ 13.6 Commodity contracts — 4.6 — 4.6 Forward exchange contracts — 9.3 — 9.3 Interest rate swaps — — — — Total liabilities measured at fair value $ — $ 13.9 $ 13.6 $ 27.5 The fair value of the commodity contracts was determined using a discounted cash flow analysis based on the terms of the contracts and observed market forward prices discounted at a currency-specific rate. Forward exchange contract fair values were determined based on quoted prices for similar assets and liabilities in active markets using inputs such as currency rates and forward points. The fair value of the interest rate swaps was determined using a discounted cash flow method based on market-based swap yield curves, considering current interest rates. The fair value of the contingent purchase consideration liabilities was determined for each arrangement individually. The fair value was determined using the income approach with significant inputs that are not observable in the market. Key assumptions include the discount rates consistent with the level of risk of achievement and probability adjusted financial projections. The expected outcomes are recorded at net present value, which requires adjustment over the life for changes in risks and probabilities. The following table sets forth a summary of changes in the value of the Company's Level 3 financial liabilities: June 30, (in millions) 2020 2019 2018 Fair value at the beginning of the year $ 13.6 $ 14.6 $ 27.6 Additions due to acquisitions — — — Changes in fair value of Level 3 liabilities 1.1 — 0.8 Payments — (1.0) (13.0) Foreign currency translation 0.1 — (0.8) Fair value at the end of the year $ 14.8 $ 13.6 $ 14.6 The fair value of contingent purchase consideration liabilities is included in other current liabilities and other non-current liabilities in the consolidated balance sheet. The change in fair value of the contingent purchase consideration liabilities, which was included in other income, net is due to the passage of time and changes in the probability of achievement used to develop the estimate. Assets and Liabilities Measured and Recorded at Fair Value on a Nonrecurring Basis In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company records assets and liabilities at fair value on a nonrecurring basis as required by U.S. GAAP. The Company measures certain assets, including the Company’s equity method investments, technology intangible assets, other intangible assets and goodwill at fair value on a nonrecurring basis when they are deemed to be other than temporarily impaired. The fair values of these assets are determined, when applicable, based on valuation techniques using the best information available, and may include quoted market prices, market comparables and discounted cash flow projections. The Company tests for impairment of its equity method investments when impairment indicators are present. Impairment tests were performed by comparing the carrying value of the Company’s investment in AMVIG at the end of each period, including interim periods, to the fair value of the investment, which was determined based on AMVIG's quoted share price which is classified in Level 1 of the fair value hierarchy. Based on the Company’s evaluation of AMVIG’s current financial condition and the Company’s intent and ability to hold its investment in AMVIG to recover the carrying value, the Company concluded that the decline in fair value was temporary at March 31, 2020, and therefore no impairment was recorded. However, the quoted share price did not recover in the fiscal fourth quarter and the Company determined that the investment was impaired as of June 30, 2020 and recorded an impairment charge of $25.6 million. The Company also recorded impairment charges of our AMVIG investment of $14.0 million in fiscal year 2019 and $36.5 million in fiscal year 2018. The Company tests indefinite-lived intangibles for impairment when facts and circumstances indicate the carrying value may not be recoverable from their undiscounted cash flows. The Company recognized non-cash impairment charges of $31.1 million in the fiscal year 2019 to reduce the carrying value of an indefinite-lived technology intangible asset to its fair value. During fiscal year 2020 and 2018, there were no indefinite-lived intangible impairment charges recorded.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company periodically uses derivatives and other financial instruments to hedge exposures to interest rates, commodity and currency risks. The Company does not hold or issue financial instruments for speculative or trading purposes. For hedges that meet the hedge accounting criteria, the Company, at inception, formally designates and documents the instrument as a fair value hedge or a cash flow hedge of a specific underlying exposure. On an ongoing basis, the Company assesses and documents that its hedges have been and are expected to continue to be highly effective. Interest Rate Risk The Company's policy is to manage exposure to interest rate risk by maintaining a mixture of fixed-rate and variable-rate debt, monitoring global interest rates and, where appropriate, hedging floating interest rate exposure or debt at fixed interest rates through various interest rate derivative instruments including, but not limited to, interest rate swaps, cross-currency interest rate swaps, and interest rate locks. For interest rate swaps that are accounted for as fair value hedges, changes in the fair value of both the hedging instruments and the underlying debt obligations are immediately recognized in interest expense. Changes in the fair value of interest rate swaps that have not been designated as hedging instruments are reported in the accompanying consolidated statement of income under other non-operating income (loss), net. As of June 30, 2020 and 2019, the total notional amount of the Company's receive-fixed/pay-variable interest rate swaps was $837.1 million and $841.1 million, respectively. At June 30, 2020, the Company had a notional amount of $100 million (equivalent to €89.0 million) cross-currency interest rate swaps outstanding. The Company did not designate the swaps as a hedging instrument and thus changes in fair value were immediately recognized in earnings. During the third quarter of fiscal year 2020, the Company entered into six Treasury lock agreements to protect against unfavorable interest rate changes relating to the highly probable issuance of long-term debt. The total notional amount of the Treasury lock of $250.0 million was designated as a cash flow hedge of an anticipated transaction and deemed these agreements to be highly effective. The associated unsecured senior note was issued on June 19, 2020, and the Company has settled these Treasury lock agreements with a $19.8 million cash payment to the counterparties. The loss associated with the settlement was recorded in accumulated other comprehensive loss and will be amortized to interest expense over the life of the unsecured senior notes, which is 10 years. Foreign Currency Risk The Company manufactures and sells its products and finances operations in a number of countries throughout the world and, as a result, is exposed to movements in foreign currency exchange rates. The purpose of the Company's foreign currency hedging program is to manage the volatility associated with the changes in exchange rates. To manage this exchange rate risk, the Company utilizes forward contracts. Contracts that qualify for hedge accounting are designated as cash flow hedges of certain forecasted transactions denominated in foreign currencies. The effective portion of the changes in fair value of these instruments is reported in accumulated other comprehensive income (loss) ("AOCI") and reclassified into earnings in the same financial statement line item and in the same period or periods during which the related hedged transactions affect earnings. The ineffective portion is recognized in earnings over the life of the hedging relationship in the same consolidated statement of income line item as the underlying hedged item. Changes in the fair value of forward contracts that have not been designated as hedging instruments are reported in the accompanying consolidated statement of income. As of June 30, 2020 and 2019, the notional amount of the outstanding forward contracts was $1.6 billion and $1.0 billion, respectively. The Company manages its currency exposure related to the net assets of its foreign operations primarily through borrowings denominated in the relevant currency. Foreign currency gains and losses from the remeasurement of external borrowings designated as net investment hedges of a foreign operation are recognized in AOCI, to the extent that the hedge is effective. The ineffective portion is immediately recognized in other non-operating income (loss), net in the consolidated statement of income. When a hedged net investment is disposed of, a percentage of the cumulative amount recognized in AOCI in relation to the hedged net investment is recognized in the condensed consolidated statement of income as part of the profit or loss on disposal. At the beginning of fiscal year 2020, the carrying value of commercial paper issued which is designated as a net investment hedge was $67.0 million. During the three months ended December 31, 2019, the Company settled $67.0 million of U.S. commercial paper issued by a non-U.S. entity, which was previously designated as a net investment hedge in its U.S. subsidiaries. The net investment hedges recorded through the point of settlement are included in AOCI and will be reclassified into earnings only upon the sale or liquidation of the related subsidiaries. The Company did not have any net investment hedges in place as of June 30, 2020. Commodity Risk Certain raw materials used in the Company's production processes are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. The Company's policy is to minimize exposure to price volatility by passing through the commodity price risk to customers, including the use of fixed price swaps. The Company purchases on behalf of customers fixed price commodity swaps to offset the exposure of price volatility on the underlying sales contracts, these instruments are cash closed out on maturity and the related cost or benefit is passed through to customers. Information about commodity price exposure is derived from supply forecasts submitted by customers and these exposures are hedged by a central treasury unit. Changes in the fair value of commodity hedges are recognized in AOCI. The cumulative amount of the hedge is recognized in the consolidated statement of income when the forecast transaction is realized. At June 30, 2020 and 2019, the Company had the following outstanding commodity contracts that were entered into to hedge forecasted purchases: June 30, 2020 June 30, 2019 Commodity Volume Volume Aluminum 44,944 tons 29,342 tons PET resin 26,006,000 lbs.

The designated foreign currency-denominated debt was included in long-term debt in the consolidated balance sheet. There are no currency net investment hedges as of June 30, 2020. Certain derivative financial instruments are subject to netting arrangements and are eligible for offset. The Company has made an accounting policy election not to offset the fair values of these instruments within the consolidated balance sheets.

In the case of unfunded plans, the Company is responsible for benefit payments as they fall due. Plan funding requirements are generally determined by local regulation and/or best practice and differ between countries.

For any funded plans in deficit (as measured under local country guidelines), the Company agrees with the trustees and plan fiduciaries to undertake suitable funding programs to provide additional contributions over time in accordance with local country requirements.

In developing the expected long-term rate of return on plan assets at each measurement date, the Company considers the plan assets' historical returns, asset allocations, and the anticipated future economic environment and long-term performance of the asset classes. While appropriate consideration is given to recent and historical investment performance, the assumption represents management's best estimate of the long-term prospective return.

Refer to Note 5, "Discontinued Operations" for more information. Forward contracts to purchase own shares The Company's employee share plans require the delivery of shares to employees in the future when rights vest or vested options are exercised. The Company currently acquires shares on the open market to deliver shares to employees to satisfy vesting or exercising commitments. This exposes the Company to market price risk. To manage the market price risk, the Company has entered into forward contracts for the purchase of its ordinary shares. As of June 30, 2020, the Company has entered into forward contracts that mature in June 2021 to purchase 2.0 million shares at an average price of $10.68. As of June 30, 2019, the Company had outstanding forward contracts for 1.0 million shares at a price of $11.00 that matured in June 2020. The forward contracts to purchase the Company's own shares are classified as a current liability. Equity is reduced by an amount equal to the fair value of the shares at inception. The carrying value of the forward contracts at each reporting period was determined based on the present value of the cost required to settle the contract.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Amcor plc is a tax resident of the United Kingdom of Great Britain and Northern Ireland ("UK"). Prior to the acquisition of Bemis, the ultimate parent of the Company at June 30, 2018 was Amcor Limited, which was a tax resident of Australia. The components of income before income taxes and equity in income (loss) of affiliated companies were as follows: Years ended June 30, (in millions) 2020 2019 2018 Domestic (35.6) $ 31.7 $ (206.6) Foreign 860.8 572.4 929.5 Total income before income taxes and equity in income (loss) of affiliated companies $ 825.2 $ 604.1 $ 722.9 Income tax expense consisted of the following: Years ended June 30, (in millions) 2020 2019 2018 Current tax Domestic 0.5 $ 7.2 $ 0.2 Foreign 300.1 91.5 192.1 Total current tax 300.6 98.7 192.3 Deferred tax Domestic 1.0 (3.2) (21.3) Foreign (114.7) 76.0 (52.2) Total deferred tax (113.7) 72.8 (73.5) Income tax expense $ 186.9 $ 171.5 $ 118.8 The following is a reconciliation of income tax computed at the UK statutory tax rate of 18.5%, 19% and 30% (Australian) for fiscal years 2020, 2019 and 2018, respectively, to income tax expense. Years ended June 30, (in millions) 2020 2019 2018 Income tax expense at statutory rate $ 152.7 $ 114.8 $ 216.9 Foreign tax rate differential 70.2 59.5 (40.8) Tax-exempt income — — 5.7 Non-deductible expenses 13.2 5.6 (7.7) Tax law changes (30.5) (2.3) (52.9) Change in valuation allowance (16.5) (5.9) 5.3 Other (2.2) (0.2) (7.7) Income tax expense $ 186.9 $ 171.5 $ 118.8 Amcor operates in over forty different jurisdictions with a wide range of statutory tax rates. The tax expense from operating in non-UK jurisdictions in excess of the UK statutory tax rate is included in the line "Foreign tax rate differential" in the above tax rate reconciliation table. For fiscal year 2020, the Company's effective tax rate was 22.6% as compared to the effective tax rates of 28.4% and 16.4% for fiscal years 2019 and 2018, respectively. The fiscal year 2020 foreign tax rate differential reflects a benefit related to Swiss tax law changes, which was mostly offset by current period tax charges related to true-up adjustments. Refer to the section "Swiss Tax Reform" in this footnote for a discussion of the benefit realized for Swiss tax law changes which the Company recognized in fiscal year 2020. For fiscal year 2020, the Company's effective tax rate for the year was higher than its UK statutory tax rate primarily due to pretax income being earned in jurisdictions outside of the UK where the applicable tax rates are higher than the UK statutory tax rate. Significant components of deferred tax assets and liabilities are as follows: June 30, (in millions) 2020 2019 Deferred tax assets Inventories 23.3 6.3 Accrued employee benefits 126.3 103.1 Provisions 5.1 14.1 Net operating loss carryforwards 252.8 275.0 Tax credit carryforwards 49.0 49.9 Accruals and other 65.9 122.7 Total deferred tax assets 522.4 571.1 Valuation allowance (363.8) (290.9) Net deferred tax assets 158.6 280.2 Deferred tax liabilities Property, plant and equipment (306.6) (329.2) Other intangible assets, including impacts from Swiss tax reform (349.5) (638.5) Trade receivables (7.2) (6.7) Derivatives (5.4) (20.4) Undistributed foreign earnings (26.9) (106.2) Total deferred tax liabilities (695.6) (1,101.0) Net deferred tax liability (537.0) (820.8) Deferred tax assets 135.4 190.9 Deferred tax liabilities (672.4) (1,011.7) Net deferred tax liability $ (537.0) $ (820.8) Deferred tax liabilities relating to other intangible assets is shown net of a deferred tax asset arising from Swiss tax reform which was recorded in the fourth quarter of fiscal year 2020 and reflected in the balance as at June 30, 2020. A valuation allowance is recorded against the deferred tax asset to bring the net amount recorded to the amount more likely than not to be realized. Refer to the section titled "Swiss Tax Reform" for more information. The Company maintains a valuation allowance on net operating losses and other deferred tax assets in jurisdictions for which it does not believe it is more likely than not to realize those deferred tax assets based upon all available positive and negative evidence, including historical operating performance, carry-back periods, reversal of taxable temporary differences, tax planning strategies and earnings expectations. The Company's valuation allowance increased by $72.9 million, increased by $20.4 million and increased by $5.3 million for fiscal year 2020, 2019 and 2018, respectively. The increase of the Company’s valuation allowance for the fiscal year ended June 30, 2020 is primarily attributed to the valuation allowance on the deferred tax asset arising from Swiss tax reform. The decrease in deferred tax liability related to undistributed foreign earnings in fiscal year 2020 includes the tax impact of the EC Remedy sale of $82.5 million. As of June 30, 2020, the Company has UK net operating losses (tax effected) and tax credits of approximately $2.9 million that do not expire. The Company has non-UK net operating losses (tax effected) and other tax attribute carryforwards of $50.9 million, the majority of which do not expire. The Company recorded valuation allowances against deferred tax assets associated with these net operating losses and tax credits. The benefits of these carryforwards are dependent upon the generation of taxable income in the jurisdictions in which they arose. The Company considers the following factors, among others, in evaluating its plans for indefinite reinvestment of its subsidiaries' earnings: (i) the forecasts, budgets and financial requirements of the Company and its subsidiaries, both for the long term and for the short term; and (ii) the tax consequences of any decision to reinvest earnings of any subsidiary. The Company has not provided deferred taxes on approximately $968.2 million of earnings in certain foreign subsidiaries because such earnings are indefinitely reinvested in its international operations. Upon distribution of such earnings in the form of dividends or otherwise, the Company may be subject to incremental foreign tax. It is not practicable to estimate the amount of foreign tax that might be payable. A cumulative deferred tax liability of $26.9 million has been recorded attributable to undistributed earnings that the Company has deemed are no longer indefinitely reinvested. The remaining undistributed earnings of the Company's subsidiaries are not deemed to be indefinitely reinvested and can be repatriated at no tax cost. Accordingly, there is no provision for income or withholding taxes on these earnings. The Company accounts for its uncertain tax positions in accordance with ASC 740, "Income Taxes." At June 30, 2020 and 2019, unrecognized tax benefits totaled $101.1 million and $102.6 million, respectively, all of which would favorably impact the effective tax rate if recognized. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the fiscal years ended June 30, 2020, 2019 and 2018, the Company's accrual for interest and penalties for these uncertain tax positions was $7.1 million, $13.8 million, and $2.9 million, respectively. The Company does not currently anticipate that the total amount of unrecognized tax benefits will result in material changes to its financial position within the next 12 months. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years presented is as follows: June 30, (in millions) 2020 2019 2018 Balance at the beginning of the year $ 102.6 $ 74.5 $ 65.1 Additions based on tax positions related to the current year 18.7 12.5 6.6 Additions for tax positions of prior years 2.3 8.2 8.9 Reductions for tax positions from prior years (13.2) (3.7) (5.3) Reductions for settlements (7.0) (5.8) — Reductions due to lapse of statute of limitations (2.3) (12.8) (0.8) Additions related to acquisitions — 29.7 — Balance at the end of the year $ 101.1 $ 102.6 $ 74.5 The Company conducts business in a number of tax jurisdictions and, as such, is required to file income tax returns in multiple jurisdictions globally. The years 2016 through 2019 remain open for examination by the United States Internal Revenue Service ("IRS"), the year 2019 remains open for examination by Her Majesty’s Revenue & Customs ("HMRC") and the years 2011 through 2019 are currently subject to audit or remain open for examination in various U.S. states and non-U.S. tax jurisdictions. The Company believes that its income tax reserves are adequately maintained taking into consideration both the technical merits of its tax return positions and ongoing developments in its income tax audits. However, the final determination of the Company's tax return positions, if audited, is uncertain and therefore there is a possibility that final resolution of these matters could have a material impact on the Company's results of operations or cash flows. Swiss Tax Reform During the fiscal year ended June 30, 2020, Swiss tax laws were changed in order to remove certain tax regimes and replace these with new measures that are hereafter referred to as "Swiss Tax Reform." In the fourth quarter of fiscal year 2020, the Company obtained confirmation from local authorities as to the methodology to calculate the future benefits and recorded the impact. The net impact was a benefit of $21.7 million, which consisted of a reduction in deferred tax expense from an allowed step-up of intangible assets for tax purposes.

Share-based Payment Arrangement [Abstract]
Share-based Compensation	Share-based Compensation The Company's equity incentive plans include grants of share options, restricted shares/units, performance shares, performance rights and share rights to directors, officers and employees. In certain countries and in selected cases, cash equivalent awards are provided in the event that the issuance of equity awards is not compliant with local legislation and tax laws. Cash-Settled Awards Cash-settled awards may be granted to directors, officers and employees of the Company in lieu of, or in addition to, participation in other programs. Such awards are accounted for as liabilities and are remeasured to fair value at each balance sheet date. Liabilities for cash-settled share-based compensation are as follows: June 30, (in millions) 2020 2019 Total carrying amount of liabilities for cash settled arrangements $ 1.1 $ 2.7 During fiscal years 2020, 2019 and 2018, the Company paid $1.6 million, $2.3 million and $1.6 million in cash, respectively, to settle these plans. Equity-Settled Awards Share Options In fiscal year 2020, share options were granted to officers and employees. The exercise price for shares options was set at the time of grant. There were no share options granted in fiscal year 2019 as they were deferred due to the transaction with Bemis. The requisite service period for outstanding share options in fiscal year 2020 ranges from two five The fair value of the share options granted in fiscal year 2020 was estimated using the Black-Scholes option pricing model that uses the assumptions noted in the following table to produce a Monte Carlo simulation. The fair value of share options granted was estimated using the following assumptions: June 30, 2020 2019 Expected dividend yield (%) (1) 4.6 % N/A Expected share price volatility (%) (2) 18.0 % N/A Risk-free interest rate (%) (3) 1.8 % N/A Expected life of options (in years) (4) 5.7 N/A (1) Determined assuming no change in dividend payout during the expected term of the option. (2) Determined based on the observed historical volatility for the Company's ordinary share price. (3) Determined based on the yields on U.S. Treasury Bonds in effect at the time of grant with maturities approximately equal to the share options' expected term. (4) Determined considering the options' contractual terms, historical exercise and post-vesting termination patterns. The Company reassesses the probability of vesting at each reporting period and adjusts compensation expense based on its probability assessment. Changes in outstanding share options for the year were as follows: Share Options Weighted-average Exercise Price Weighted-average Contractual Life (in millions) (in years) Share options outstanding at June 30, 2019 10.8 $ 10.32 3.6 Granted 49.6 10.33 5.7 Exercised (0.2) 6.08 6.9 Forfeited (4.2) 10.63 6.0 Share options outstanding at June 30, 2020 56.0 $ 10.32 5.3 Vested and exercisable at June 30, 2020 2.5 $ 8.78 1.6 The aggregate intrinsic value (difference in exercise price and closing price at that date) for all share options outstanding at June 30, 2020 was zero. The aggregate intrinsic value for share options vested and exercisable at June 30, 2020 was $3.6 million. The Company received $1.1 million, $19.3 million and $28.1 million and realized a tax benefit of $0.2 million, $5.5 million and $12.3 million on the exercise of stock options during the fiscal years ended June 30, 2020, 2019 and 2018, respectively. During the fiscal years ended June 30, 2020, 2019 and 2018, the intrinsic value associated with the exercise of share options was $0.7 million, $8.3 million and $20.6 million, respectively. The weighted-average grant date fair value of share options granted and the fair value of share options vested was as follows: Years ended June 30, 2020 2019 2018 Weighted average grant date fair value of share options granted $ 0.7 N/A $ 1.1 Fair value of share options vested (in millions) $ 0.3 $ 3.8 $ 5.3 Restricted Shares/Units Restricted shares/units may be granted to directors, officers and employees of the Company and vest on terms as described in the award. The restrictions prevent the participant from disposing of the restricted shares/units during the vesting period. The fair value of restricted shares/units is determined based on the closing price of the Company's shares on the grant date. Changes in the restricted shares/units for the year were as follows: Restricted Shares/Units Weighted-average Grant Date Fair Value (in millions) Non-vested restricted shares/units at June 30, 2019 0.5 $ 11.4 Granted 0.4 10.1 Exercised (0.2) 12.1 Forfeited — — Non-vested restricted shares/units at June 30, 2020 0.7 $ 10.4 The weighted-average grant date fair value of restricted shares granted and the fair value of restricted shares/units vested was as follows: Years ended June 30, 2020 2019 2018 Weighted-average grant date fair value of restricted shares granted $ 10.1 N/A $ 11.5 Fair value of restricted shares/units vested (in millions) $ 2.1 $ 0.2 $ 1.8 Performance Rights and Performance Shares In fiscal year 2020, performance rights or performance shares (awarded to U.S. participants in place of performance rights) were granted to officers and employees. There were no performance rights or performance shares granted in fiscal year 2019 as they were deferred due to the transaction with Bemis. The requisite service period for outstanding performance rights or performance shares in fiscal year 2020 ranges from two The fair value of the performance rights and performance shares granted in fiscal year 2020 was estimated using the Black-Scholes option pricing model that uses the assumptions noted in the following table to produce a Monte Carlo simulation.

Earnings Per Share [Abstract]
Earnings Per Share Computations	Earnings Per Share Computations The Company applies the two-class method when computing its earnings per share ("EPS"), which requires that net income per share for each class of share be calculated assuming all of the Company's net income is distributed as dividends to each class of share based on their contractual rights. Basic EPS is computed by dividing net income available to ordinary shareholders by the weighted-average number of ordinary shares outstanding after excluding the ordinary shares to be repurchased using forward contracts.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Legal Proceedings	Contingencies and Legal Proceedings Contingencies - Brazil The Company's operations in Brazil are involved in various governmental assessments and litigation, principally related to claims for excise and income taxes. The Company will vigorously defend its positions and believes it will prevail on most, if not all, of these matters. The Company does not believe that the ultimate resolution of these matters will materially impact the Company's consolidated results of operations, financial position or cash flows. Under customary local regulations, the Company's Brazilian subsidiaries may need to post cash or other collateral if a challenge to any administrative assessment proceeds to the Brazilian court system; however, the level of cash or collateral already pledged or potentially required to be pledged would not significantly impact the liquidity of Amcor. At June 30, 2020 and 2019, the Company has recorded an accrual of $11.9 million and $16.4 million, respectively, included in other non-current liabilities in the consolidated balance sheet and has estimated a reasonably possible loss exposure in excess of the accrual of $18.4 million and $23.7 million, respectively. The litigation process is subject to many uncertainties and the outcome of individual matters cannot be accurately predicted. The Company routinely assesses these matters as to probability of ultimately incurring a liability and records the best estimate of the ultimate loss in situations where the likelihood of an ultimate loss is probable. The Company's assessments are based on its knowledge and experience, but the ultimate outcome of any of these matters may differ from the Company's estimates. As of June 30, 2020, the Company provided letters of credit of $34.0 million, judicial insurance of $0.9 million and deposited cash of $10.1 million with the courts to continue to defend the cases referenced above. Contingencies - Environmental Matters The Company, along with others, has been identified as a potentially responsible party ("PRP") at several waste disposal sites under U.S. federal and related state environmental statutes and regulations and may face potentially material environmental remediation obligations. While the Company benefits from various forms of insurance policies, actual coverage may not, or only partially, cover the total potential exposures. The Company has recorded $17.1 million aggregate accruals for its share of estimated future remediation costs as these sites. In addition to the matters described above, the Company has also recorded aggregate accruals of $46.6 million for potential liabilities for remediation obligations at various worldwide locations that are owned or operated by the Company, or were formerly owned or operated. While the Company believes that its accruals are adequate to cover its future obligations, there can be no assurance that the ultimate payments will not exceed the accrued amounts. Nevertheless, based on the available information, the Company does not believe that its potential environmental obligations will have a material adverse effect upon its liquidity, results of operations or financial condition. Legal Proceedings On April 18, 2019, prior to the closure of the Amcor and Bemis transaction, litigation funding firm, Burford Capital, notified Bemis on behalf of two shareholder funds (BCIM Strategic Value Master Fund LP and BCIM SV SMA I LLC) that the funds would not accept the fixed exchange ratio for Amcor shares and instead intended to file a case asking a Missouri state court to appraise the value of their Bemis shares and compensate them accordingly. On June 24, 2019, the Burford funds sent a formal written demand for payment of the fair value of the funds’ shares. On September 6, 2019, the Burford funds filed a Petition for Appraisal of Stock in the Missouri court. On November 4, 2019, Bemis filed an Answer to the Petition for Appraisal of Stock. On June 24, 2020, the parties entered into a Confidential Settlement Agreement and Release of all claims and two days later the case was dismissed with prejudice. Two lawsuits brought by purported holders of Bemis stock against Bemis and Bemis directors and officers are pending in federal court in the U.S. District Court for the Southern District of New York, in which plaintiffs are seeking damages for alleged violations of the Securities Exchange Act of 1934, as amended, and U.S. Securities and Exchange Commission rules and regulations. Plaintiffs allege a failure to disclose adequately information in the proxy statement issued in connection with the Amcor-Bemis merger. The cases are: Dixon, et al. v. Bemis Company, Inc. et al. and Stein v. Bemis Company, Inc. et al ., which were instituted on April 15, 2019 and April 17, 2019, respectively. On March 10, 2020 the federal court in the U.S. District Court for the Southern District of New York consolidated the two pending cases into a single class action. In addition, a purported holder of Bemis stock filed a putative derivative suit in the Cole County Circuit Court, Nineteenth Judicial District of Missouri, against Bemis directors and Amcor, alleging that the directors breached fiduciary duties in connection with the Amcor-Bemis merger and that Amcor aided and abetted breaches of fiduciary duty. The case is Scarantino, et al. v. Amcor Limited, et al. , which was instituted on April 19, 2019. The Company intends to defend the claims made in the pending actions. It is too early for the Company to provide any reliable assessment of the likely quantum of any damages that may become payable if its defense is unsuccessful in whole or in part. Although it is not possible at present to establish a reliable assessment of damages, there can be no assurance that any damages that may be awarded will not be material to the results of operations or financial condition of the Company.

Segment Reporting [Abstract]
Segments	Segments The Company's business is organized and presented in the two reportable segments outlined below: Flexibles: Consists of operations that manufacture flexible and film packaging in the food and beverage, medical and pharmaceutical, fresh produce, snack food, personal care, and other industries. Rigid Packaging: Consists of operations that manufacture rigid plastic containers for a broad range of predominantly beverage and food products, including carbonated soft drinks, water, juices, sports drinks, milk-based beverages, spirits and beer, sauces, dressings, spreads and personal care items and plastic caps for a wide variety of applications. Other consists of the Company's equity method investments, including AMVIG, undistributed corporate expenses, intercompany eliminations and other business activities. Operating segments are organized along the Company's product lines and geographical areas. In conjunction with the acquisition of Bemis, the Company reassessed its segment reporting structure in the first fiscal quarter of 2020 and elected to disaggregate the Flexibles Americas operating segment into Flexibles North America and Flexibles Latin America. The five Flexibles operating segments (Flexibles Europe, Middle East and Africa; Flexibles North America, Flexibles Latin America; Flexibles Asia Pacific and Specialty Cartons) have been aggregated in the Flexibles reporting segment as they exhibit similarity in economic characteristics and future prospects, similarity in the products they offer, their production technologies, the customers they serve, the nature of their service delivery models, and their regulatory environments. In the fourth quarter of fiscal year 2019, in connection with the acquisition of Bemis, the Company changed its measure of segment performance from adjusted operating income to adjusted earnings before interest and tax ("Adjusted EBIT") from continuing operations. The Company's chief operating decision maker, the Global Management Team ("GMT"), evaluates performance and allocates resources based on Adjusted EBIT from continuing operations. The Company defines Adjusted EBIT as operating income adjusted to eliminate the impact of certain items that the Company does not consider indicative of its ongoing operating performance and to include equity in income (loss) of affiliated companies. The GMT consists of the Managing Director and Chief Executive Officer and his direct reports and provides strategic direction and management oversight of the day to day activities of the Company. The accounting policies of the reportable segments are the same as those in the consolidated financial statements and are discussed in Note 2, "Significant Accounting Policies." The Company also has investments in operations in AMVIG that are accounted for under the equity method of accounting and, accordingly, those results are not included in segment net sales.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation Policy	Basis of Presentation and Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany transactions and balances have been eliminated. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").
Business Combinations Policy	Business Combinations: The Company uses the acquisition method of accounting, which requires separate recognition of assets acquired and liabilities assumed from goodwill, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the fair value of any non-controlling interests in the acquiree over the net of the acquisition date fair values of the assets acquired and liabilities assumed. During the measurement period, which may be up to one year from the acquisition date, the Company has the ability to record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated statement of income.
Discontinued Operations Presentation Policy	Discontinued Operations Presentation: The consolidated financial statements and related notes reflect the three plants in Europe acquired as part of the Bemis acquisition as a discontinued operation in fiscal 2019 as the Company agreed to divest of these plants as a condition of approval from the European Commission. See Note 5, "Discontinued Operations," for more information on discontinued operations. The plants were divested in the first quarter of fiscal 2020.
Estimates and Assumptions Required Policy	Estimates and Assumptions Required: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates are based on historical experience and various assumptions believed to be reasonable under the circumstances. Management evaluates these estimates on an ongoing basis and adjusts or revises the estimates as circumstances change. As future events and their impacts cannot be determined with precision, actual results may differ from these estimates. In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the results of the periods presented. The impact that the 2019 Novel Coronavirus ("COVID-19") pandemic will have on the Company's consolidated operations is uncertain. The Company has considered the potential impacts of the COVID-19 pandemic when developing the Company's estimates and judgements as of June 30, 2020, and will continue to evaluate the extent of the impact on the Company's business and consolidated financial statements. The Company's accounting estimates and assumptions may change over time in response to COVID-19 and the change could be material in future periods.
Translation of Foreign Currencies Policy	Translation of Foreign Currencies: The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s subsidiaries is generally the local currency of such entity. Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the entity’s functional currency are remeasured at the exchange rate as of the balance sheet date to the entity’s functional currency. Foreign currency transaction gains and losses related to short-term and long-term debt are recorded in other non-operating income (loss), net, in the consolidated statement of income. The Company recorded such foreign currency transaction net loss of $0.4 million, net gain of $1.1 million and net loss of $82.7 million during the fiscal years ended June 30, 2020, 2019 and 2018, respectively. All other foreign currency transaction gains and losses are recorded in other income, net in the consolidated statement of income. These foreign currency transaction net gains amounted to $21.4 million, $8.9 million and $1.0 million during the fiscal years ended June 30, 2020, 2019 and 2018, respectively. Upon consolidation, the results of operations of subsidiaries whose functional currency is other than the reporting currency of the Company are translated using average exchange rates in effect during each year. Assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at the exchange rate as of the balance sheet date, while equity balances are translated at historical rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Highly Inflationary Accounting: A highly inflationary economy is defined as an economy with a cumulative inflation rate of approximately 100 percent or more over a three-year period. If a country's economy is classified as highly inflationary, the financial statements of the foreign entity operating in that country must be remeasured to the functional currency of the parent. As of July 1, 2018, the Argentine economy was designated as highly inflationary for accounting purposes. Accordingly, the U.S. dollar replaced the Argentine peso as the functional currency for the Company's subsidiaries in Argentina. The impact of
Revenue Recognition Policy	Revenue Recognition: The Company generates revenue by providing its customers with flexible and rigid packaging serving a variety of markets including food, consumer products and healthcare end markets. The Company enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the terms under which the Company does business with a specific customer. The Company also sells to some customers solely based on purchase orders. The Company has concluded for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. All revenue recognized in the consolidated statement of income is considered to be revenue from contracts with customers. The Company typically satisfies the obligation to provide packaging to customers at a point in time upon shipment when control is transferred to customers. Revenue is recognized net of allowances for returns and customer claims and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company does not have any material contract assets or contract liabilities. The Company disaggregates revenue based on geography. Disaggregation of revenue is presented in Note 20, "Segments". Significant Judgments Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company identified potential performance obligations in its customer master supply agreements and determined that none of them are capable of being distinct as the customer can only benefit from the supplied packaging. Therefore, the Company has concluded that it has one performance obligation to supply packaging to customers. The Company may provide variable consideration in several forms which are determined through its agreements with customers. The Company can offer prompt payment discounts, sales rebates or other incentive payments to customers. Sales rebates and other incentive payments are typically awarded upon achievement of certain performance metrics, including volume. The Company accounts for variable consideration using the most likely amount method. The Company utilizes forecasted sales data and rebate percentages specific to each customer agreement and updates its judgment of the amounts to which the customer is entitled each period. The Company enters into long term agreements with certain customers, under which it is obligated to make various up-front payments for which it expects to receive a benefit in excess of the cost over the term of the contract. These up-front payments are deferred and reflected in prepaid expenses and other current assets or other non-current assets on its consolidated balance sheet. Contract incentives are typically recognized as a reduction to revenue over the term of the customer agreement. Practical Expedients The Company sells primarily through its direct sales force. Any external sales commissions are expensed when incurred because the amortization period would be one year or less. External sales commission expense is included in selling, general and administrative expense in the consolidated statement of income. The Company accounts for shipping and handling activities as fulfillment costs. Accordingly, shipping and handling costs are classified as a component of cost of products sold while amounts billed to customers are classified as a component of net sales. The Company excluded from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected from the customer, including sales taxes, value added taxes, excise taxes and use taxes. Accordingly, the tax amounts are not included in net sales. The Company does not adjust the promised consideration for the time value of money for contracts where the difference between the time of payment and performance is one year or less.
Research and Development Policy	Research and Development: Research and development expenditures are expensed as incurred.
Restructuring Costs Policy	Restructuring Costs: Restructuring costs are recognized when the liability is incurred. The Company calculates severance obligations based on its standard customary practices. Accordingly, the Company records provisions for severance when probable and estimable and the Company has committed to the restructuring plan. In the absence of a standard customary
Cash and Cash Equivalents Policy	Cash and Cash Equivalents: The Company considers all highly liquid temporary investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents include certificates of deposit that can be readily liquidated without penalty at the Company’s option. Cash equivalents are carried at cost which approximates fair market value.
Trade Receivables, Net Policy	Trade Receivables, Net: Trade accounts receivable, net, are stated at the amount the Company expects to collect, which is net of an allowance for sales returns and the estimated losses resulting from the inability of its customers to make required payments. When determining the collectability of specific customer accounts, a number of factors are evaluated, including: customer creditworthiness, past transaction history with the customer and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. The Company has an allowance for doubtful accounts of $35.3 million and $34.4 million recorded at June 30, 2020 and 2019, respectively, in trade receivables, net, on the consolidated balance sheet. The current year expense to adjust the allowance for doubtful accounts is recorded within selling, general and administrative expenses in the consolidated statement of income. The Company enters into factoring arrangements from time to time to sell trade receivables to third-party financial institutions. Sales of receivables are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 860, Transfers and Servicing ("ASC 860"). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred without recourse to the Company, are reflected as a reduction of trade receivables, net on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. Agreements that allow the Company to maintain effective control over the transferred receivables and which do not qualify as a true sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within trade receivables, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statement of income primarily as a reduction of net sales. Factored receivables not qualifying as a true sale were accounted for as secured borrowings. As of June 30, 2020 and 2019, amounts factored recorded under trade receivables, net and short-term debt, were zero and $152.7 million, respectively.
Inventories Policy	Inventories: Inventories are valued primarily at the lower of cost, as determined by the first-in, first-out ("FIFO") method, or net realizable value. Inventory values using the FIFO method of accounting approximate replacement cost. Inventories are summarized at June 30, 2020 and 2019 as follows: (in millions) 2020 2019 Raw materials and supplies $ 808.6 $ 864.6 Work in process and finished goods 1,127.6 1,180.9 Less: inventory reserves (104.3) (91.7) Inventory, net $ 1,831.9 $ 1,953.8
Property, Plant and Equipment, Net Policy	Property, Plant and Equipment, Net: Property, plant and equipment ("PP&E"), net is carried at cost less accumulated depreciation and impairment and includes expenditures for new facilities and equipment and those costs which substantially increase the useful lives or capacity of existing PP&E. Cost of constructed assets includes capitalized interest incurred during the construction period. Maintenance and repairs that do not improve efficiency or extend economic life are expensed as incurred. PP&E, including assets held under finance leases, is depreciated using the straight-line method over the estimated useful lives of assets or, in the case of leasehold improvements and leased assets, over the period of the lease or useful life of the asset, whichever is shorter, as described below. The Company periodically reviews these estimated useful lives and, when appropriate, changes are made prospectively. Leasehold land Over lease term Land improvements Up to 30 years Buildings Up to 45 years Plant and equipment Up to 25 years Finance leases Shorter of lease term or 5 - 25 years For tax purposes, the Company generally uses accelerated methods of depreciation. The tax effect of the difference between book and tax depreciation has been provided for as deferred income taxes.
Impairment of Long-Lived Assets Policy	Impairment of Long-lived Assets: The Company reviews long-lived assets, primarily PP&E and certain identifiable intangible assets with finite lives, for impairment when facts or circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying values are reduced to the estimated fair value. Fair values are determined based on quoted market values, discounted cash flows or external appraisals, as applicable. Impairment losses recognized in the consolidated statement of income were as follows: Years ended June 30, (in millions) 2020 2019 2018 Selling, general and administrative ("SG&A") expenses $ 0.7 $ 47.7 $ 0.4 Restructuring and related expenses 20.8 27.4 4.0 Total impairment losses recognized in the consolidated statement of income $ 21.5 $ 75.1 $ 4.4
Leasing Policy	Leasing: The Company has operating leases for certain manufacturing sites, office space, warehouses, land, vehicles and equipment. Right-of-use lease assets and lease liabilities are recognized at the commencement date based on the present value of the remaining lease payments over the lease term, which includes renewal periods the Company is reasonably certain to exercise. The Company reevaluates its leases on a regular basis to consider the economic and strategic incentives of exercising lease renewal options. Short term leases with a term of twelve months or less, including reasonably certain holding periods, are not recorded on the consolidated balance sheet. As the Company's leases generally do not provide an implicit rate, the Company uses its incremental borrowing rate as of the commencement date to determine the present value of lease payments. The Company recognizes expense for operating leases on a straight-line basis over the lease term in the consolidated statement of income. Certain leasing arrangements require variable payments that are dependent on usage or output or may vary for other reasons. Variable lease payments that do not depend on an index or rate are excluded from lease payments in the measurement of the right-of-use asset and lease liability and recognized as expense in the period in which the obligation for the payments occur.
Goodwill Policy	Goodwill: Goodwill represents the excess of cost over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but instead tested annually or whenever events and circumstances indicate an impairment may have occurred during the year. Among the factors that could trigger an impairment review are a reporting unit’s operating results significantly declining relative to its operating plan or historical performance, and competitive pressures and changes in the general markets in which it operates. In light of the COVID-19 pandemic and related global impacts, the Company considered the potential for goodwill impairment of its reporting units in the third fiscal quarter of 2020. The review did not indicate an impairment triggering event as of March 31, 2020. All goodwill is assigned to a reporting unit, which is defined as the operating segment. In conjunction with the acquisition of Bemis, the Company reassessed its segment reporting structure in the first fiscal quarter of 2020 and elected to disaggregate the Flexibles Americas operating segment into Flexibles North America and Flexibles Latin America. With this change, the Company has six reporting units with goodwill that are assessed for potential impairment. In performing the required impairment tests, the Company has the option to first assess qualitative factors to determine if it is necessary to perform a quantitative assessment for goodwill impairment. If the qualitative assessment concludes that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. The Company's quantitative assessment utilizes present value (discounted cash flow) methods to determine the fair value of the reporting units with goodwill. Determining fair value using discounted cash flows requires considerable judgment and is sensitive to changes in underlying assumptions and market factors. Key assumptions relate to revenue growth, projected operating income growth, terminal values, and discount rates. If current expectations of future growth rates and margins are not met, or if market factors outside of Amcor’s control, such as factors impacting the applicable discount rate, or economic or political conditions in key markets, change significantly, then goodwill allocated to one or more reporting units may be impaired. The Company performs its annual impairment analysis in the fourth quarter of each year. A quantitative impairment analysis was performed in the fourth fiscal quarter for all reporting units for the fiscal years ended 2020 and 2018, while a qualitative analysis was performed for the fiscal year ended 2019. The Company’s annual impairment analysis for all three fiscal years concluded that goodwill was not impaired. The Company’s quantitative goodwill analysis in fiscal years 2020 and 2018 concluded that the fair values substantially exceeded the carrying amounts for each reporting unit.
Other Intangible Assets, Net Policy	Other Intangible Assets, Net: Contractual or separable intangible assets that have finite useful lives are amortized against income using the straight-line method over their estimated useful lives, with original periods ranging from one Costs incurred to develop software programs to be used solely to meet the Company's internal needs have been capitalized as computer software within other intangible assets.
Fair Value Measurements Policy	Fair Value Measurements: The fair values of the Company's financial assets and financial liabilities reflect the amounts that would be received to sell the assets or paid to transfer the liabilities in an orderly transaction between market participants at the measurement date (exit price). The Company determines fair value based on a three-tiered fair value hierarchy. The hierarchy consists of: • Level 1: fair value measurements represent exchange-traded securities which are valued at quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date; • Level 2: fair value measurements are determined using input prices that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data; and
Financial Instruments Policy	Financial Instruments: The Company recognizes all derivative instruments on the consolidated balance sheet at fair value. The impact on earnings from recognizing the fair values of these instruments depends on their intended use, their hedge designation and their effectiveness in offsetting changes in the fair values of the exposures they are hedging. Derivatives not designated as hedging instruments are adjusted to fair value through income. Depending on the nature of derivatives designated as hedging instruments, changes in the fair value are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized. Gains or losses, if any, related to the ineffective portion of any hedge are recognized through earnings over the life of the hedging relationship. See Note 11, "Derivative Instruments," for more information regarding specific derivative instruments included on the Company’s consolidated balance sheet, such as forward foreign currency exchange contracts, currency swap contracts, and interest rate swap arrangements, among other derivative instruments.
Employee Benefit Plans Policy	Employee Benefit Plans: The Company sponsors various defined contribution plans to which it makes contributions on behalf of employees. The expense under such plans was $63.5 million, $39.9 million and $39.8 million for the fiscal years ended June 30, 2020, 2019 and 2018, respectively. The Company sponsors a number of defined benefit plans that provide benefits to current and former employees. For the company-sponsored plans, the relevant accounting guidance requires that management make certain assumptions relating to the long-term rate of return on plan assets, discount rates used to determine the present value of future obligations and expenses, salary inflation rates, mortality rates and other assumptions. The Company believes that the accounting estimates related to its pension plans are critical accounting estimates because they are highly susceptible to change from period to period based on the performance of plan assets, actuarial valuations, market conditions and contracted benefit changes. The selection of assumptions is based on historical trends and known economic and market conditions at the time of valuation, as well as independent studies of trends performed by the Company’s actuaries. However, actual results may differ substantially from the estimates that were based on the critical assumptions. The Company recognizes the funded status of each defined benefit pension plan in the consolidated balance sheet. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability. Pension plan liabilities are revalued annually, or when an event occurs that requires remeasurement, based on updated assumptions and information about the individuals covered by the plan. Accumulated actuarial gains and losses in excess of a 10 percent corridor and the prior service cost are amortized on a straight-line basis from the date recognized over the average remaining service period of active participants or over the average life expectancy for plans with significant inactive participants. The service costs related to defined benefits are included in operating income. The other components of net benefit cost other than service cost are recorded within other non-operating income (loss), net in the consolidated statement of income
Equity Method Investments Policy	Equity Method Investments: Investments in ordinary shares of companies, in which the Company believes it exercises significant influence over operating and financial policies, are accounted for using the equity method of accounting. Under this method, the investment is carried at cost and is adjusted to recognize the investor’s share of earnings or losses of the investee after the date of acquisition and is adjusted for impairment whenever it is determined that a decline in the fair value below the cost basis is other than temporary. The fair value of the investment then becomes the new cost basis of the investment and it is not adjusted for subsequent recoveries in fair value. Impairment losses have been recognized for the Company's equity investment in AMVIG Holdings Limited ("AMVIG") in the last three fiscal years. See Note 7, "Equity Method Investments," for more information regarding the Company's equity method investments.
Share-Based Compensation Policy	Share-based Compensation: Amcor has a variety of equity incentive plans. For employee awards with a service or market condition, compensation expense is recognized over the vesting period on a straight-line basis using the grant date fair value of the award and the estimated number of awards that are expected to vest. For awards with a performance condition, the Company must reassess the probability of vesting at each reporting period and adjust compensation cost based on its probability assessment. The Company also has cash-settled share-based compensation plans which are accounted for as liabilities. Such share-based awards are remeasured to fair value at each reporting period. The Company estimates forfeitures based on employee level, economic conditions, time remaining to vest and historical forfeiture experience.
Income Taxes Policy	Income Taxes: The Company uses the asset and liability method to account for income taxes. Deferred income taxes reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based upon enacted income tax laws and tax rates. Income tax expense or benefit is provided based on earnings reported in the consolidated financial statements. The provision for income tax expense or benefit differs from the amounts of income taxes currently payable because certain items of income and expense included in the consolidated financial statements are recognized in different time periods by taxing authorities. Deferred tax assets, including operating loss, capital loss and tax credit carryforwards, are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that any portion of these tax attributes will not be realized. In addition, from time to time, management must assess the need to accrue or disclose uncertain tax positions for proposed adjustments from various tax authorities who regularly audit the Company in the normal course of business. In making these assessments, management must often analyze complex tax laws of multiple jurisdictions. Accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company records the related interest expense and penalties, if any, as tax expense in the tax provision. See Note 16, "Income Taxes," for more information on the Company's income taxes.
