Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 1. Basis of Presentation and Significant Accounting Policies Basis of Presentation Our independent registered public accounting firm has not audited the accompanying interim financial statements. We derived the condensed consolidated balance sheet at September 30, 2021 from the audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021 (the “Fiscal 2021 Form 10-K”). In the opinion of management, all normal recurring adjustments necessary for the fair presentation of the Condensed Consolidated Financial Statements have been included for the interim periods reported. We have condensed or omitted certain notes and other information from the interim financial statements presented in this report. Therefore, these interim financial statements should be read in conjunction with the Fiscal 2021 Form 10-K. The results for the three and nine months ended June 30, 2022 are not necessarily indicative of results that may be expected for the full year. Reclassifications and Adjustments Effective October 1, 2021, we reorganized our segment reporting to four reportable segments: Corrugated Packaging, Consumer Packaging, Global Paper and Distribution. Prior period amounts have been recast throughout the Notes to Condensed Consolidated Financial Statements, as applicable, to conform to the new segment structure. These changes did not impact our consolidated financial statements. See “Note 6. Segment Information” for additional information. Certain other amounts in prior periods have been reclassified to conform with the current year presentation. COVID-19 Pandemic The global impact of the COVID-19 pandemic ("COVID") continues to evolve and our first priority has been and continues to be the health and safety of our teammates. We have taken, and continue to take, actions to protect the health and safety of our teammates during COVID and we have incurred and continue to incur costs for safety, cleaning and other items related to COVID. The pandemic has affected our operational and financial performance to varying degrees and the extent of its effect on our operational and financial performance will continue to depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration, scope and severity of the pandemic (including due to new or continuing variants), the actions taken to contain or mitigate its impact (including the distribution and effectiveness of vaccines and vaccine boosters), and the direct and indirect economic effects of the pandemic and related containment measures and government responses, among others. Our net sales have been negatively impacted by COVID, to varying degrees, primarily in the last half of fiscal 2020, and we have experienced and are currently experiencing higher supply chain costs and labor shortages, in part due to the impacts of COVID. Productivity, primarily in our Corrugated Packaging segment, has been negatively impacted by COVID-related absenteeism, particularly in the second quarter of fiscal 2022. The Company’s assessment of the future magnitude and duration of COVID, as well as other factors, may change and could result in changes in our accounting estimates and assumptions used to prepare our financial statements in conformity with generally accepted accounting principles in the U.S. ("GAAP"). Ransomware Incident As previously disclosed, on January 23, 2021 we detected a ransomware incident impacting certain of our systems. Promptly upon our detection of this incident, we initiated response and containment protocols and our security teams, supplemented by leading cyber defense firms, worked to remediate this incident. We undertook extensive efforts to identify, contain and recover from this incident quickly and securely. Our teams worked to maintain our business operations and minimize the impact on our customers and teammates. In our second quarter of fiscal 2021 Form 10‐Q, we announced that all systems were back in service. All of our mills and converting locations began producing and shipping paper and packaging at pre-ransomware levels in March 2021 or earlier. As previously disclosed, we estimated the pre-tax income impact of the lost sales and operational disruption of this incident on our operations in the second quarter of fiscal 2021 was approximately $50 million, as well as approximately $20 million of ransomware recovery costs, primarily professional fees. In addition, we incurred approximately $9 million of ransomware recovery costs in the third quarter of fiscal 2021. In the fourth quarter of fiscal 2021, we recorded a $15 million credit for preliminary recoveries – approximately $10 million as a reduction of SG&A excluding intangible amortization and approximately $5 million as a reduction of cost of goods sold. In the three and nine months ended June 30, 2022, we received additional business interruption recoveries of $10 million and $20 million, respectively, related to the ransomware incident, which we recorded as a reduction of Cost of goods sold and presented in Net cash provided by operating activities on our condensed consolidated statements of cash flows. While we expect to recover substantially all of the remaining ransomware losses from cyber and business interruption insurance from various carriers in future periods, the recovery process proceeds from carrier to carrier up the coverage layers after the preceding layer is resolved, which lends itself to a lengthy process. Additionally, discussions and/or disputes over the extent of insurance coverage for claims are not uncommon and generally take time to be resolved. See “Note 1. Description of Business and Summary of Significant Accounting Policies — Ransomware Incident” of the Notes to Consolidated Financial Statements section in the Fiscal 2021 Form 10-K for additional information. Significant Accounting Policies See “Note 1. Description of Business and Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements section in the Fiscal 2021 Form 10-K for a summary of our significant accounting policies. Recent Accounting Developments New Accounting Standards — Recently Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes”. This ASU removes certain exceptions from recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. It also reduces complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. This ASU is effective for fiscal years beginning after December 15, 2020 (fiscal 2022 for us) and interim periods within those fiscal years. We adopted the provisions of ASU 2019-12 beginning October 1, 2021. The adoption of this ASU did not have a material impact on our consolidated financial statements. In July 2021, the FASB issued ASU 2021-05, “Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments”. This ASU requires lessors to classify leases as operating leases if they have variable lease payments that do not depend on an index or rate and would have selling losses at lease commencement if they were classified as sales-type or direct financing leases. For lessors that had adopted Accounting Standards Codification (“ASC”) 842, "Leases" as of July 19, 2021, when the amendments were issued, the amendments can be applied either retrospectively or prospectively and are effective for annual periods beginning after December 15, 2021 (fiscal 2023 for us) and interim periods within those annual periods. Early adoption is permitted. We early adopted this ASU using the prospective transition approach beginning October 1, 2021. The adoption of this ASU did not have a material impact on our consolidated financial statements. New Accounting Standards — Recently Issued In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”. This ASU clarifies that contractual sale restrictions should not be considered in measuring the fair value of equity securities. This ASU is effective for fiscal years beginning after December 15, 2023 (fiscal 2025 for us), including interim periods therein, with early adoption permitted. We are evaluating the impact of this ASU. In March 2022, the FASB issued ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method”. This ASU expands and clarifies the portfolio layer method for fair value hedges of interest rate risk. This ASU is effective for fiscal years beginning after December 15, 2022 (fiscal 2024 for us), including interim periods therein, with early adoption permitted. We are evaluating the impact of this ASU. In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832) – Disclosures by Business Entities about Government Assistance”. This ASU aims to increase the transparency of government assistance through the annual disclosure of the types of assistance, an entity’s accounting for the assistance and the effect of the assistance on an entity’s financial statements. This ASU is effective for annual periods beginning after December 15, 2021 (fiscal 2023 for us), with early adoption permitted. We are evaluating the impact of this ASU. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805) – Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”. This ASU requires an entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606 “Revenue from Contracts with Customers” (“ASC 606”). This ASU is intended to reduce diversity in practice and increase comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination. This ASU is effective for fiscal years beginning after December 15, 2022 (fiscal 2024 for us), including interim periods therein, with early adoption permitted. We are evaluating the impact of this ASU. 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”. This ASU provides temporary optional expedients and exceptions for applying GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate. In January 2021, the FASB issued ASU 2021-01, which adds implementation guidance to clarify certain optional expedients in Topic 848. The ASUs can be adopted after their respective issuance dates through December 31, 2022. We are evaluating our contracts and the impact of optional expedients provided by these ASUs. See “Note 11. Debt” for additional information on our recent credit facility changes.
