Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and New Accounting Pronouncements	Basis of Presentation and New Accounting Pronouncements Basis of Presentation The unaudited consolidated financial statements and notes thereto of Rayonier Advanced Materials Inc. (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, these consolidated financial statements and notes reflect all adjustments (all of which are normal recurring adjustments) necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. These statements and notes should be read in conjunction with the consolidated financial statements and supplementary data included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC on March 1, 2021. On August 28, 2021, the Company completed the previously announced sale of its lumber and newsprint facilities and certain related assets (the “Purchased Assets”) located in Ontario and Québec Canada to GreenFirst Forest Products, Inc. (“GreenFirst”). As a result of the sale, the lumber and newsprint assets and operations have been presented as discontinued operations and the Company has reclassified certain prior year amounts to conform to this presentation. Unless otherwise stated, information in these notes to consolidated financial statements relates to continuing operations. The Company presents businesses that represent components as discontinued operations when they meet the criteria for held for sale or are sold, and their disposal represents a strategic shift that has, or will have, a major effect on our operations and financial results. See Note 2 —Discontinued Operations for additional information. Coronavirus Pandemic During 2020, the Company’s businesses were significantly impacted by the coronavirus ("COVID-19") pandemic. While market demand and pricing for certain of the Company’s products began to recover towards the end of 2020 and have continued to improve throughout 2021, the Company's operations remain vulnerable to a reversal of these trends or other continuing negative effects caused by COVID-19. In its operating facilities and work spaces, the Company continues to maintain protocols previously implemented to reduce the potential spread of COVID-19 and ensure the safety of its employees and continuity of operations. New or Recently Adopted Accounting Pronouncements There have been no new or recently adopted accounting pronouncements impacting the Company’s unaudited consolidated interim financial statements. Subsequent Events Events and transactions subsequent to the consolidated balance sheets date have been evaluated for potential recognition and disclosure through the date of issuance of these Consolidated Financial Statements.
