Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Glatfelter and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. We prepared these financial statements in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles” or “GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements. In our opinion, the financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. When preparing these financial statements, we have assumed you have read the audited consolidated financial statements included in our 2020 Annual Report on Form 10-K.
Discontinued Operations | Discontinued Operations The results of operations and cash flows of our former Specialty Papers business have been classified as discontinued operations for all periods presented in the condensed consolidated statements of income.
Accounting Estimates | Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes actual results may differ from those estimates and assumptions.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU No. 2019-12”). The update eliminates, clarifies, and modifies certain guidance related to the accounting for income taxes. We adopted ASU No. 2019-12 effective January 1, 2021 and it did not have a material impact on our financial statements.
