Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the six months ended December 31, 2021 are not necessarily indicative of the results that may be expected for the year ending June 30, 2022. The consolidated balance sheet at June 30, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information on the Company's accounting policies and footnotes, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2021 filed with the Securities and Exchange Commission (the “SEC”).
Foreign Currency Translation	Foreign Currency Translation The financial statements of the Company’s operations are generally measured using the local currency as the functional currency. Adjustments to translate the assets and liabilities of operations outside the U.S. into U.S. dollars are accumulated as a component of other comprehensive income utilizing period-end exchange rates. Since July 1, 2018, the Company has accounted for its Argentine operations as highly inflationary.
Depreciation, Depletion, and Amortization	Depreciation Depreciation expense was $64 million and $48 million for the three months ended December 31, 2021 and 2020, respectively. Depreciation expense was $122 million and $94 million for the six months ended December 31, 2021 and 2020, respectively. Depreciation expense includes amortization of assets related to finance leases. The Company charges repairs and maintenance costs to expense as incurred.
Research and Development Costs	Research and Development Costs The Company expenses research and development costs as incurred. Research and development costs amounted to $6 million and $5 million for the three months ended December 31, 2021 and 2020, respectively. Research and development costs amounted to $12 million for the six months ended December 31, 2021 and 2020.
Marketable Securities	Marketable SecuritiesThe Company classifies its marketable securities as available-for-sale, because it may sell certain of its marketable securities prior to the stated maturity for various reasons, including management of liquidity, credit risk, duration, relative return, and asset allocation. The Company determines the fair value of each marketable security in its portfolio at each period end and recognizes gains and losses in the portfolio in other comprehensive income. As of December 31, 2021, the amortized cost basis of marketable securities approximates fair value and all outstanding marketable securities mature within one year.
Recent Financial Accounting Standards	Recent Financial Accounting Standards Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions related to the incremental approach for intra-period allocation, deferred tax recognition requirement for changes in equity method investments and non-U.S. subsidiaries, and methodology for calculating income taxes in an interim period. The guidance also simplifies certain aspects of the accounting for franchise taxes, the accounting for step-up in the tax basis of goodwill, and accounting for the change in the enacted change in tax laws or rates. The Company adopted the guidance on July 1, 2021. The adoption of this guidance did not have a material impact on the Company’s financial condition or results of operations. In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plan, which removes certain disclosures and added additional disclosures around weighted-average interest crediting rates for cash balance plans and explanation for significant gains and losses related to change in the benefit obligation for the period. The Company adopted the guidance on July 1, 2021. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards Not Adopted as of December 31, 2021 In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance to ease the potential burden in accounting for the discontinuation of a reference rate such as LIBOR, formerly known as the London Interbank Offered Rate, because of reference rate reform. The expedients and exceptions provided by the guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. The ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements.
