Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Reportable Segments | Reportable Segments - the Company has two reportable segments: (1) Filtration & Advanced Materials ("FAM"), focused primarily on filtration media and components, advanced films, coating and converting solutions, and extruded mesh products, and (2) Sustainable & Adhesive Solutions ("SAS") focused primarily on tapes, labels, liners, specialty paper, packaging and healthcare solutions.
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements and the notes thereto have been prepared in accordance with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission ("SEC") and do not include all the information and disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). However, such information reflects all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of results for the interim periods. The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for the full year. The unaudited condensed consolidated financial statements and these notes thereto included herein should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on February 27, 2025.
Reclassifications | Reclassifications Selling expense and General expense prior year amounts in the Condensed Consolidated Statements of Income (Loss) have been reclassified to Selling and general expense and Intangible asset amortization expense to conform to the current year presentation for comparative purposes.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the revenues and expenses during the reporting period. Actual results could differ significantly from these estimates. The significant estimates underlying our unaudited condensed consolidated financial statements include, but are not limited to, inventory valuation, goodwill valuation, useful lives of tangible and intangible assets, equity-based compensation, derivatives, receivables valuation, pension, postretirement and other benefits, taxes and contingencies.
Recently Adopted and Issued Accounting Standards | Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendment enhances reportable segment disclosure requirements, primarily regarding significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of other segment items and expanded interim disclosures that align with those required annually, among other provisions. The amendments in this ASU became effective on a retrospective basis for annual periods beginning January 1, 2024, and interim periods within those annual periods beginning January 1, 2025. The adoption of this standard is reflected in Note 14. Segment Information. Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." The amendment enhances income tax disclosure requirements, particularly regarding the effective tax rate reconciliation and income taxes paid. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024. The adoption of this accounting standard will not have an impact on our consolidated financial statements, but this standard will require certain additional disclosures. In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures." The ASU requires a public business entity to provide disaggregated disclosures of certain categories of expenses on an annual and interim basis including purchases of inventory, employee compensation, depreciation, and intangible asset amortization for each income statement line item that contains those expenses. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures. In July 2025, the FASB issued ASU 2025-05, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." The ASU provide entities with a practical expedient to simplify the estimation of expected credit losses on current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606, Revenue from Contracts with Customers, by allowing the assumption that current conditions as of the balance sheet date will not change during the remaining life of the asset. The ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, "Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software." The ASU modernizes existing internal use software guidance to adapt to concepts and processes present in an agile development environment. Key amendments include the elimination of software project development stages in favor of a requirement to commence capitalization once management has authorized the project, committed to funding, and project completion is probable. This ASU is effective for interim and annual reporting periods beginning after December 15, 2027 with early adoption permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s consolidated financial statements.
