Commitments And Contingencies [Abstract]
Commitments and Contingencies	Note 13. Commitments and Contingencies Health and Safety Our business involves the use of heavy equipment, machinery and chemicals and requires the performance of activities that create safety exposures. The health and safety of our teammates is our most important responsibility, and we have established safety policies, programs, procedures and training for our manufacturing operations. We are subject to a broad range of foreign, federal, state and local laws and regulations relating to occupational health and safety, and our safety program includes measures required for compliance. In addition, our program includes the ongoing identification and elimination of workplace exposures that can lead to injuries and sharing of health and safety best practices, including processes to create resilient, error tolerant safety systems. Failure to comply with applicable health and safety laws and regulations could subject us to fines, corrective actions or other sanctions. Certain governmental authorities in locations where we do business have established asbestos standards for the workplace. Although we do not use asbestos in manufacturing our products, asbestos containing material (“ACM”) is present in some of the facilities we lease or own. For those facilities where ACM is present and ACM is subject to regulation, we have established procedures for properly managing it. We have incurred, and will continue to incur, capital expenditures to meet our health and safety compliance requirements, as well as to improve our safety systems. We do not believe that future compliance with occupational health and safety laws and regulations will have a material adverse effect on our results of operations, financial condition or cash flows. Environmental We are subject to numerous international, federal, state, local and other environmental laws and regulations, including those governing discharges to air, soil and water; the management, treatment and disposal of hazardous substances, solid waste and hazardous wastes; the investigation and remediation of contamination resulting from historical site operations; and requirements relating to the use of chemicals in packaging. We are also subject to the requirements of environmental permits and similar authorizations issued by various governmental authorities. Complex and lengthy processes may be required to obtain and renew approvals, permits, and licenses for new, existing or modified facilities. Additionally, the use and handling of various chemicals or hazardous materials require release prevention plans and emergency response procedures. Our compliance initiatives related to these laws and regulations could result in significant costs, which could negatively impact our results of operations, financial condition and cash flows. Failure to comply with environmental laws and regulations, or any permits and authorizations required thereunder, could subject us to fines or other sanctions, corrective action requirements and litigation. We have been named as a potentially responsible party (“PRP”) in environmental remediation actions under various federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”). Many of these proceedings involve the cleanup of hazardous substances at sites that received waste from many different sources. While joint and several liability is authorized under CERCLA and analogous state laws, liability for CERCLA cleanups is typically shared with other PRPs, and costs are commonly allocated according to relative amounts of waste deposited and other factors. We believe we have insurance and contractual indemnification rights that may allow us to recover certain defense and other costs at some CERCLA sites. Other remediation costs typically associated with the cleanup of hazardous substances at our current, closed or formerly-owned facilities, are recorded as liabilities in our balance sheet. Remediation costs are recorded in our financial statements when they become probable and reasonably estimable. See “Note 17. Commitments and Contingencies” of the Notes to Consolidated Financial Statements section in the Fiscal 2021 Form 10-K for information related to environmental matters. As of June 30, 2022, we had $10.9 million reserved for environmental liabilities on an undiscounted basis, of which $1.6 million is included in other long-term liabilities and $9.3 million is included in other current liabilities, including amounts accrued in connection with environmental obligations relating to manufacturing facilities that we have closed. We believe the liability for these matters was adequately reserved at June 30, 2022. Litigation During fiscal 2018, we submitted formal notification to withdraw from the PIUMPF and recorded a liability associated with the withdrawal. Subsequently, in fiscal 2019 and 2020, we received demand letters from PIUMPF, including a demand for withdrawal liabilities and for our proportionate share of PIUMPF's accumulated funding deficiency, and we refined our liability, the impact of which was not significant. We began making monthly payments for the PIUMPF withdrawal liabilities in fiscal 2020, excluding the accumulated funding deficiency demands. We dispute the PIUMPF accumulated funding deficiency demands. In February 2020, we received a demand letter from PIUMPF asserting that we owe $51.2 million for our pro-rata share of PIUMPF’s accumulated funding deficiency, including interest. Similarly, in April 2020, we received an updated demand letter related to a subsidiary of ours asserting that we owe $1.3 million of additional accumulated funding deficiency, including interest. In July 2021, the PIUMPF filed suit against us in the U.S. District Court for the Northern District of Georgia claiming the right to recover our pro rata share of the pension fund’s accumulated funding deficiency. We believe we are adequately reserved for this matter. See “Note 4. Retirement Plans — MEPPs” of the Notes to Condensed Consolidated Financial Statements for more information regarding our withdrawal liabilities. We have been named a defendant in asbestos-related personal injury litigation. To date, the costs resulting from the litigation, including settlement costs, have not been significant. As of June 30, 2022, there were approximately 1,925 such lawsuits. We believe that we have substantial insurance coverage, subject to applicable deductibles and policy limits, with respect to asbestos claims. We also have valid defenses to these asbestos-related personal injury claims and intend to continue to defend them vigorously. Should the volume of litigation grow substantially, it is possible that we could incur significant costs resolving these cases. We do not expect the resolution of pending asbestos litigation and proceedings to have a material adverse effect on our results of operations, financial condition or cash flows. In any given period or periods, however, it is possible such proceedings or matters could have a material adverse effect on our results of operations, financial condition or cash flows. At June 30, 2022, we had $17.5 million reserved for these matters. We are a defendant in a number of other lawsuits and claims arising out of the conduct of our business. While the ultimate results of such suits or other proceedings against us cannot be predicted with certainty, we believe the resolution of these other matters will not have a material adverse effect on our results of operations, financial condition or cash flows. Brazil Tax Liability We are challenging claims by the Brazil Federal Revenue Department that we underpaid tax, penalties and interest associated with a claim that a subsidiary of MeadWestvaco Corporation (the predecessor of WestRock MWV, LLC) had reduced its tax liability related to the goodwill generated by the 2002 merger of two of its Brazil subsidiaries. The matter has proceeded through the Brazil Administrative Council of Tax Appeals (“CARF”) principally in two proceedings, covering tax years 2003 to 2008 and 2009 to 2012. The tax and interest claim relating to tax years 2009 to 2012 was finalized and is now the subject of an annulment action we filed in the Brazil federal court. CARF notified us of its final decision regarding the tax, penalties and interest claims relating to tax years 2003 to 2008 on June 3, 2020. We have filed an annulment action in Brazil federal court with respect to that decision as well. The dispute related to penalties for tax years 2009 to 2012 remains before CARF. We assert that we have no liability in these matters. The total amount in dispute before CARF and in the annulment actions relating to the claimed tax deficiency was R$722 million ($138 million) as of June 30, 2022, including various penalties and interest. The U.S. dollar equivalent has fluctuated significantly due to changes in exchange rates. The amount of our uncertain tax position reserve for this matter, that excludes certain penalties, is included in the unrecognized tax benefits table in our Fiscal 2021 Form 10-K, see “Note 6. Income Taxes” of the Notes to Consolidated Financial Statements. Resolution of the uncertain tax positions could have a material adverse effect on our cash flows and results of operations or materially benefit our results of operations in future periods depending upon their ultimate resolution. Guarantees We make certain guarantees in the normal course of conducting our operations, for compliance with certain laws and regulations, or in connection with certain business dispositions. The guarantees include items such as funding of net losses in proportion to our ownership share of certain joint ventures, debt guarantees related to certain unconsolidated entities acquired in acquisitions, indemnifications of lessors in certain facilities and equipment operating leases for items such as additional taxes being assessed due to a change in tax law and certain other agreements. We estimate our exposure to these matters to be less than $50 million. As of June 30, 2022, we had recorded $0.8 million for the estimated fair value of these guarantees. We are unable to estimate our maximum exposure under operating leases because it is dependent on potential changes in the tax laws; however, we believe our exposure related to guarantees would not have a material impact on our results of operations, financial condition or cash flows.

Guarantees

We make certain guarantees in the normal course of conducting our operations, for compliance with certain laws and regulations, or in connection with certain business dispositions. The guarantees include items such as funding of net losses in proportion to our ownership share of certain joint ventures, debt guarantees related to certain unconsolidated entities acquired in acquisitions, indemnifications of lessors in certain facilities and equipment operating leases for items such as additional taxes being assessed due to a change in tax law and certain other agreements.
