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, 2021, as filed with the SEC on March 1, 2022. As a result of the sale of its lumber and newsprint assets in August 2021 to GreenFirst Forest Products, Inc. (“GreenFirst”), the Company presents the results for those operations as discontinued operations. 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 the Company’s operations and financial results. See Note 2 — Discontinued Operations for additional information. 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. No subsequent events were identified.

The Company recently sold the GreenFirst common shares for $43 million. Prior to the sale, the GreenFirst common shares were accounted for at fair value, with changes in fair value recorded in the Consolidated Statements of Income and Comprehensive Income. See Note 10 — Fair Value Measurements for additional information. The cash received at closing was preliminary and subject to final purchase price and other sale-related adjustments.

Pursuant to the terms of the asset purchase agreement, GreenFirst and the Company continue efforts to finalize the closing inventory valuation adjustment. In connection with the transaction, the parties entered into a Transition Services Agreement ("TSA") whereby the Company would provide certain transitional services to GreenFirst, including information technology, accounting, treasury and other services following the closing of the transaction.

Environmental Remediation Obligations [Abstract]
Environmental Liabilities	Environmental Liabilities An analysis of liabilities for the six months ended June 25, 2022 is as follows: Balance, December 31, 2021 $ 171,222 Increase in liabilities 1,599 Payments (1,626) Foreign currency adjustments (222) Balance, June 25, 2022 170,973 Less: Current portion (11,291) Long-term environmental liabilities $ 159,682 In addition to the estimated liabilities, the Company is subject to the risk of reasonably possible additional liabilities in excess of the established reserves due to potential changes in circumstances and future events, including, without limitation, changes to current laws and regulations; changes in governmental agency personnel, direction, philosophy and/or enforcement policies; developments in remediation technologies; increases in the cost of remediation, operation, maintenance and monitoring of its environmental liability sites; changes in the volume, nature or extent of contamination to be remediated or monitoring to be undertaken; the outcome of negotiations with governmental agencies and non-governmental parties; and changes in accounting rules or interpretations. Based on information available as of June 25, 2022, the Company estimates this exposure could range up to approximately $85 million, although no assurances can be given that this amount will not be exceeded given the factors described above. These potential additional costs are attributable to several sites and other applicable liabilities. Further, this estimate excludes reasonably possible liabilities which are not currently estimable primarily due to the factors discussed above. Subject to the previous paragraph, the Company believes established liabilities are sufficient for probable costs expected to be incurred over the next 20 years with respect to its environmental liabilities. However, no assurances are given they will be sufficient for the reasons described above, and additional liabilities could have a material adverse effect on the Company’s financial position, results of operations and cash flows.

Derivatives Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives Instruments	Derivative Instruments The Company’s earnings and cash flows are subject to fluctuations due to changes in interest rates and foreign currency exchange rates. The Company allows for the use of derivative financial instruments to manage interest rate and foreign currency exchange rate exposure but does not allow derivatives to be used for speculative purposes. All derivative instruments are recognized on the consolidated balance sheets at their fair value and are either designated as a hedge of a forecasted transaction or undesignated. Changes in the fair value of a derivative designated as a hedge are recorded in other comprehensive income until earnings are affected by the hedged transaction and are then reported in current earnings. Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current earnings. In December 2020, the Company terminated all outstanding derivative instruments, which had been previously designated as hedging instruments and had various maturity dates through 2028. Accumulated gains and losses associated with these instruments were deferred as a component of accumulated other comprehensive income (loss) to be recognized in earnings as the underlying hedged transactions occur and affect earnings. Foreign Currency Exchange Rate Risk Foreign currency fluctuations affect investments in foreign subsidiaries and foreign currency cash flows related to third party purchases, product shipments, and foreign-denominated debt. The Company is also exposed to the translation of foreign currency earnings to the U.S. dollar. Management may use foreign currency forward contracts to selectively hedge its foreign currency cash flows exposure and manage risk associated with changes in currency exchange rates. The Company’s principal foreign currency exposure is to the Canadian dollar, and to a lesser extent, the euro. There were no derivatives designated as hedging instruments during the three and six months ended June 25, 2022. The effects of derivatives designated as hedging instruments, the related changes in AOCI and the gains and losses in income for the three and six months ended June 26, 2021, is as follows: Three Months Ended June 26, 2021 Derivatives Designated as Hedging Instruments Gain (Loss) Recognized in OCI on Derivative Gain (Loss) Reclassified from AOCI into Income Location on Statement of Income Foreign exchange forward contracts $ — $ 2,260 Cost of sales Foreign exchange forward contracts $ — $ (102) Interest income and other, net Six Months Ended June 26, 2021 Derivatives Designated as Hedging Instruments Gain (Loss) Recognized in OCI on Derivative Gain (Loss) Reclassified from AOCI into Income Location on Statement of Income Foreign exchange forward contracts $ — $ 4,088 Cost of sales Foreign exchange forward contracts $ — $ (202) Interest income and other, net The after-tax amounts of unrealized gains (losses) in AOCI related to hedge derivatives are presented below: June 25, 2022 December 31, 2021 Foreign exchange cash flow hedges $ (690) $ (847)

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following table presents the carrying amount, estimated fair values and categorization under the fair value hierarchy for financial instruments held by the Company, using market information and what management believes to be appropriate valuation methodologies: June 25, 2022 December 31, 2021 Carrying Fair Value (b) Carrying Fair Value (b) Assets: Level 1 Level 2 Level 1 Level 2 Cash and cash equivalents Cash $ 145,643 $ 145,643 $ — $ 253,307 $ 253,307 $ — Money market funds 2,105 2,105 — — — — Investment in GreenFirst equity securities — — — 38,510 — 38,510 Liabilities (a): Fixed-rate long-term debt $ 898,091 $ — $ 852,923 $ 919,455 $ — $ 964,308 (a) Liabilities exclude finance lease obligation. (b) The Company did not have Level 3 assets or liabilities at June 25, 2022 or December 31, 2021. The Company uses the following methods and assumptions in estimating the fair value of its financial instruments: Cash and cash equivalents — Cash and cash equivalents are all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase and the carrying amount is equal to fair market value. The Company had $2 million of money market funds as of June 25, 2022, measured using level 1 inputs. The Company did not have money market funds as of December 31, 2021. Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. The variable rate debt adjusts with changes in the market rate, therefore the carrying value approximates fair value. Investment in GreenFirst shares — The Company received 28,684,433 common shares of GreenFirst in connection with the sale of the lumber and newsprint assets to GreenFirst, which the Company was required to hold for a minimum of six months following the close of the transaction. Accordingly, prior to February 28, 2022, the fair value of these shares reflected a discount for lack of marketability (“DLOM”) given the restriction on sale by the Company. The primary inputs in the fair value estimate during the minimum holding period were expected term, dividend yield, volatility and risk-free rate. All inputs to the DLOM were observable. GreenFirst is based in Canada and currently does not pay a dividend. On May 2, 2022, the Company sold the 28,684,433 for $43 million. The shares sale agreement contains a purchase price protection clause whereby the Company is entitled to participate in further share price appreciation under certain circumstances over the next 18 months. The following were the key inputs at each measurement date: December 31, 2021 At closing of transaction Expected Term 0.16 years 0.5 years Risk-free rate 0.10 % 0.20 % Dividend yield — — Volatility 73.77 % 92.04 % DLOM 6.77 % 14.38 %

Common Stock Buyback On January 29, 2018, the Board of Directors authorized a share buyback program pursuant to which the Company may, from time to time, purchase shares of its common stock with an aggregate purchase price of up to $100 million. During the three and six months ended June 25, 2022, and June 26, 2021, the Company did not repurchase any common shares under this buyback program. As of June 25, 2022, there was approximately $60 million of share repurchase authorization remaining under the program. The Company does not expect to utilize any further authorization in the near future. Shareholder Rights Plan On March 21, 2022, the Company adopted a shareholder rights plan (the “Rights Agreement”) whereby a significant penalty is imposed upon any person or group which acquires beneficial ownership of 10% or more of the Company Common Stock without the approval of the Board of Directors (the “Board”). Also on this date, the Board declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock of the Company, par value $0.01 per share (“Company Common Stock”), which was paid to Company stockholders of record as of the close of business on March 31, 2022. The Rights trade with, and are inseparable from, shares of the Company Common Stock. Each Right will allow its holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock for $35.00, once the Rights become exercisable. This portion of a Preferred Share will give the stockholder approximately the same dividend, voting and liquidation rights as would one share of Company Common Stock. The Rights will not be exercisable until 10 days after the public announcement or public disclosure that a person or group has become an “Acquiring Person” by obtaining beneficial ownership of 10% or more of the outstanding Company Common Stock (including certain derivative positions), subject to certain exceptions. The Rights will expire on March 20, 2023.

Share-Based Payment Arrangement [Abstract]
Incentive Stock Plans	Incentive Stock Plans The Company’s total stock-based compensation for the three months ended June 25, 2022, and June 26, 2021 was expense of $4 million and $1 million, respectively. Stock based compensation expense for the six months ended June 25, 2022 and June 26, 2021 was $7 million and $385 thousand, respectively. The Company made new grants of restricted stock units and performance-based stock units to certain employees during the first six months of 2022. The 2022 restricted stock unit awards cliff vest after three years. The 2022 performance-based stock unit awards measure total shareholder return (“TSR”) on an absolute basis and relative to peers. Participants can earn between 0 and 250 percent of the target award. Performance below the threshold for the absolute TSR would result in a zero payout for the TSR metric. There is a performance-based stock award and cash unit stock award that will be measured using the same objectives but paid and accounted for separately. As required by Accounting Standards Codification 718, Compensation-Stock Compensation, the portion of the award to be settled in cash is classified as a liability and remeasured to fair value at the end of each reporting period until settlement. In March 2022, the performance-based share units granted in 2019 vested without meeting the performance thresholds, resulting in no stock units being awarded and no shares of common stock issued. The following table summarizes the activity on the Company’s incentive stock awards for the six months ended June 25, 2022: Stock Options Restricted Stock Units Performance-Based Stock Units Options Weighted Average Exercise Price Awards Weighted Average Grant Date Fair Value Awards Weighted Average Grant Date Fair Value Outstanding at January 1, 2022 111,124 $ 39.47 927,556 $ 8.72 1,459,716 $ 6.51 Granted — — 1,328,931 5.50 1,284,535 8.24 Forfeited — — (161,708) 5.79 (1,159,319) 6.71 Exercised or settled — — (307,213) 11.08 — — Expired or cancelled (32,464) 38.24 — — — — Outstanding at June 25, 2022 78,660 $ 39.94 1,787,566 $ 6.18 1,584,932 $ 7.77

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company has defined benefit pension and other long-term and postretirement plans covering certain union and non-union employees, primarily in the U.S. and Canada. The defined benefit pension plans are closed to new participants. The liabilities for these plans are calculated using actuarial estimates and management assumptions. These estimates are based on historical information, along with certain assumptions about future events. During 2019, the Company settled certain Canadian pension liabilities through the purchase of annuity contracts with an insurance company. The settlement resulted in the recognition of a $1 million loss during the three and six months ended June 26, 2021. Additionally, the Company recorded an additional $1 million loss during the three and six months ended June 25, 2022, related to the final asset surplus distribution to the plans’ participants. The settlements were recognized in “Other components of net periodic benefit costs” in the Consolidated Statements of Income and Comprehensive Income (Loss) for the three and six months ended June 26, 2021, and in “Other components of net periodic benefit costs” in the Consolidated Statements of Income for the three and six months ended June 25, 2022. The components of net periodic benefit costs from these plans that have been recorded are shown in the following table: Pension Postretirement Three Months Ended Three Months Ended Components of Net Periodic Benefit Cost June 25, 2022 June 26, 2021 June 25, 2022 June 26, 2021 Service cost $ 2,171 $ 2,600 $ 352 $ 363 Interest cost 4,597 4,446 215 176 Expected return on plan assets (8,379) (9,673) — — Amortization of prior service cost 39 177 (30) (38) Amortization of losses 2,473 4,086 15 2 Pension settlement loss 1,179 890 — — Total net periodic benefit cost $ 2,080 $ 2,526 $ 552 $ 503 Pension Postretirement Six Months Ended Six Months Ended Components of Net Periodic Benefit Cost June 25, 2022 June 26, 2021 June 25, 2022 June 26, 2021 Service cost $ 4,347 $ 5,181 $ 705 $ 725 Interest cost 9,203 8,851 431 351 Expected return on plan assets (16,707) (19,279) — — Amortization of prior service cost 78 352 (61) (76) Amortization of losses 4,946 8,163 30 6 Pension settlement loss 1,179 890 — — Total net periodic benefit cost $ 3,046 $ 4,158 $ 1,105 $ 1,006 Service cost is included in cost of sales and selling, general and administrative expenses in the statements of income, as appropriate.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate on the loss from continuing operations for the three and six months ended June 25, 2022, was an expense of 18 percent and 12 percent, respectively, compared to an effective tax benefit rate of 153 percent and 77 percent on the loss from continuing operations for the three and six months ended June 26, 2021. The current quarter and year to date June 25, 2022 effective rate differs from the federal statutory rate of 21 percent primarily due to disallowed interest deductions in the U.S. and nondeductible executive compensation, partially offset by US tax credits and tax return to accrual adjustments. The effective tax rate benefit for the three and six months ended June 26, 2021 differs from the federal statutory rate primarily due to a tax benefit recognized by remeasuring the Company’s Canadian deferred tax assets at a higher Canadian blended statutory rate. The statutory tax rate is higher as a result of changing the allocation of income between the Canadian provinces as a result of the sale of Forest Products and Newsprint. Other factors impacting the effective benefit rate are return to accrual adjustments and tax credits, partially offset by nondeductible interest expense in the U.S. and lower tax deductions on vested stock compensation. The Company’s deferred tax assets include approximately $18 million of disallowed U.S. interest deductions that the Company does not believe it will be able to realize, including $7 million recognized as a reduction to tax expense in the six months ended June 26, 2022. In December of 2019 the American Institute of Certified Public Accountants (“AICPA”) issued Technical Questions and Answers (“TQA”) 3300.01-02 which asserts that certain material evidence regarding the realizability of disallowed U.S. interest deductions should be ignored when assessing the need for a valuation allowance. In strict compliance with the AICPA’s TQA, the Company has not recognized a valuation allowance on a portion of the deferred tax assets generated from disallowed interest. The Company has a $21 million receivable related to a U.S. federal tax refund, which is expected to be collected within the next twelve months.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company has no material changes to the purchase obligations presented in Note 21 — Commitments and Contingencies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 1, 2022, that are outside the normal course of business for the six months ended June 25, 2022. The Company’s purchase obligations continue to primarily consist of commitments for the purchase of natural gas, steam energy, wood chips, and electricity contracts entered into within the normal course of business. The Company leases certain buildings, machinery and equipment under various operating leases. See Note 5 — Leases , for additional information. Litigation and Contingencies Duties on Canadian softwood lumber sold to the U.S . The Company previously operated six softwood lumber mills in Ontario and Quebec, Canada and exported softwood lumber into the United States from Canada. In connection with these exports, the Company paid approximately $112 million in softwood lumber duties through August 28, 2021, recorded as expense in the periods incurred. The Company currently has a $22 million long-term receivable associated with the December 2020 and 2021 determinations of the revised rates for the 2017, 2018 and 2019 periods. Cash is not expected to return to the Company until final resolution of the softwood lumber dispute, which remains subject to legal challenges and to USDOC further administrative review processes covering periods after December 31, 2019. As part of the sale of its lumber assets, the Company retained all rights and obligations to softwood lumber duties, generated or incurred through the closing date of the transaction. Other . In addition to the above, the Company is engaged in various legal and regulatory actions and proceedings, and has been named as a defendant in various lawsuits and claims arising in the ordinary course of its business. While the Company has procured reasonable and customary insurance covering risks normally occurring in connection with its businesses, the Company has in certain cases retained some risk through the operation of self-insurance, primarily in the areas of workers’ compensation, property insurance and general liability. These other lawsuits and claims, either individually or in aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. Guarantees and Other The Company provides financial guarantees as required by creditors, insurance programs and various governmental agencies. As of June 25, 2022, the Company had net exposure of $38 million from various standby letters of credit, primarily for financial assurance relating to environmental remediation, credit support for natural gas and electricity purchases, and guarantees related to foreign retirement plan obligations. These standby letters of credit represent a contingent liability. The Company would only be liable upon its default on the related payment obligations. The letters of credit have various expiration dates and will be renewed as required. The Company had surety bonds of $89 million as of June 25, 2022, primarily to comply with financial assurance requirements relating to environmental remediation and post closure care, to provide collateral for the Company’s workers’ compensation program, and to guarantee taxes and duties for products shipped internationally. These surety bonds expire at various dates and are expected to be renewed annually as required. LignoTech Florida (“LTF”) is a venture in which the Company owns 45 percent and its partner Borregaard ASA owns 55 percent. The Company is a guarantor of LTF’s financing agreements and, in the event of default, expects it would only be liable for its proportional share of any repayment under the agreements. The Company’s proportion of the LTF financing agreement guarantee was $32 million at June 25, 2022. The Company has not recorded any liabilities for these financial guarantees in its consolidated balance sheets, either because the Company has recorded the underlying liability associated with the guarantee or the guarantee is dependent on the Company’s own performance and, therefore, is not subject to the measurement requirements or because the Company has calculated the estimated fair value of the guarantee and determined it to be immaterial based upon the current facts and circumstances that would trigger a payment obligation. It is not possible to determine the maximum potential amount of the liability under these potential obligations due to the unique set of facts and circumstances likely to be involved with each provision.

Basis of Presentation	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, 2021, as filed with the SEC on March 1, 2022.
New or Recently Adopted Accounting Pronouncements	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	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.
Fair Value Measurements	The Company uses the following methods and assumptions in estimating the fair value of its financial instruments: Cash and cash equivalents — Cash and cash equivalents are all highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase and the carrying amount is equal to fair market value. The Company had $2 million of money market funds as of June 25, 2022, measured using level 1 inputs. The Company did not have money market funds as of December 31, 2021. Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. The variable rate debt adjusts with changes in the market rate, therefore the carrying value approximates fair value.
