Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | On November 4, 2024 (the “Closing Date”), Treasure Holdco, Inc. (“Treasure”), which was a wholly owned subsidiary of Berry Global Group, Inc. (“Berry”), completed its merger (the “Transaction”) with the Glatfelter Corporation (“GLT”) which concurrently changed its name to Magnera Corporation (the “Company,” “we,” or “Magnera”). As a result, pre-Transaction Treasure shareholders received shares of Magnera representing 90% of the combined company and GLT shareholders retained 10%. As Treasure was identified as the accounting acquirer, the prior year presentation represents standalone Treasure results with the acquisition method of accounting being applied to the assets acquired and liabilities assumed of GLT. See Note 3—Acquisition. The accompanying unaudited Consolidated and Combined Financial Statements of Magnera Corporation have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim reporting.
Use of Estimates | In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts and disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In 2023, the Financial Accounting Standards Board ("FASB") issued guidance with the goal of providing more information about reportable segments, including disaggregated expense information. The Company adopted all required disclosures requirements in fiscal 2025. In 2023, the FASB issued guidance with the goal of providing more information in the income tax reconciliation table and regarding income taxes paid. The Company is currently evaluating the impact of adopting this guidance. In 2024, the FASB issued guidance with the goal of providing more expense information of certain categories of expenses that are included in line items on the face of the statements of earnings. The Company is currently evaluating the impact of adopting this guidance.
Revenue and Accounts Receivable | Revenue is recognized when performance obligations are satisfied, in an amount reflecting the consideration to which the Company expects to be entitled. We consider the promise to transfer products to be our sole performance obligation. Generally, our revenue is recognized for standard promised goods at the time of shipment, when title and risk of loss pass to the customer. The Company disaggregates revenue based on geography.
