Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Summary of Significant Accounting Policies	NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Graphic Packaging Holding Company (“GPHC” and, together with its subsidiaries, the “Company”) is committed to providing consumer packaging that makes a world of difference. The Company is a leading provider of sustainable, fiber-based consumer packaging solutions for a wide variety of products to food, beverage, foodservice and other consumer products companies. The Company operates on a global basis, is one of the largest producers of folding cartons in the United States ("U.S.") and Europe, and holds leading market positions in coated-recycled paperboard ("CRB"), coated unbleached kraft paperboard ("CUK") and solid bleached sulfate paperboard ("SBS"). The Company’s customers include many of the world’s most widely recognized companies and brands with prominent market positions in beverage, food, foodservice, and other consumer products. The Company strives to provide its customers with innovative sustainable packaging solutions designed to deliver marketing and performance benefits at a competitive cost by capitalizing on its low-cost paperboard mills and converting plants, its proprietary carton and packaging designs, and its commitment to quality and service. On January 1, 2018, GPHC, a Delaware corporation, International Paper Company, a New York corporation (“IP”), Graphic Packaging International Partners, LLC, a Delaware limited liability company formerly known as Gazelle Newco LLC and a wholly-owned subsidiary of the Company (“GPIP”), and Graphic Packaging International, LLC, a Delaware limited liability company formerly known as Graphic Packaging International, Inc. and a direct subsidiary of GPIP (“GPIL”), completed a series of transactions pursuant to an agreement dated October 23, 2017 among the foregoing parties (the “Transaction Agreement”). Pursuant to the Transaction Agreement (i) a wholly-owned subsidiary of the Company transferred its ownership interest in GPIL to GPIP; (ii) IP transferred its North America Consumer Packaging (“NACP”) business to GPIP, which was then subsequently transferred to GPIL; (iii) GPIP issued membership interests to IP, and IP was admitted as a member of GPIP; and (iv) GPIL assumed certain indebtedness of IP (the "NACP Combination"). During 2020, GPIP purchased 32.5 million partnership units from IP for $500 million in cash, fully redeeming the 18.2 million partnership units that were required to be redeemed in cash. On February 16, 2021, the Company announced that IP had notified the Company of its intent to exchange additional partnership units. Per an agreement between the parties, on February 19, 2021, GPIP purchased 9.3 million partnership units from IP for $150 million in cash, and IP exchanged 15.3 million partnership units for an equivalent number of shares of GPHC common stock. On May 21, 2021, IP exchanged its remaining 22.8 million partnership units for an equivalent number of shares of GPHC common stock. As required by the parties' agreement, these shares were immediately sold by IP. As a result, IP has no ownership interest remaining in GPIP as of May 21, 2021. In connection with both the February 19, 2021 and May 21, 2021 exchanges, pursuant to elections under Section 754 of the Internal Revenue Code, the Company obtained an increase with respect to the tax basis in the assets of GPIP and certain of its subsidiaries. As a result, payments pursuant to the Tax Receivable Agreement (“TRA”), executed in connection with the formation of GPIP on January 1, 2018, are required. The TRA provides for the payment by the Company to IP of 50% of the present value of any tax benefits projected to be realized by the Company upon IP’s exchange of its membership interest into GPHC stock. As such, the Company recorded TRA liabilities of $43 million and $66 million, for the February 19, 2021 and May 21, 2021 exchanges, respectively. The TRA liabilities were recorded through adjustments to Capital in Excess of Par Value during the first and second quarters of 2021, respectively. In accordance with the terms of the TRA, the Company settled the liability for the February exchange during the third quarter and settled the liability for the May exchange during the fourth quarter of 2021. Additionally, the Company recorded an adjustment through Capital in Excess of Par Value to decrease its net domestic Deferred Tax Liability (“DTL”) by $175 million in connection with both the February and May exchanges. The decrease in the DTL reflects the change in the outside basis difference associated with the Company’s investment in GPIP and includes the impact of the tax basis step up triggered by the exchanges pursuant to Section 754 of the Internal Revenue Code in addition to other changes to book and tax basis as a result of the Company’s increased ownership interest in GPIP. Basis of Presentation and Principles of Consolidation The Company’s Consolidated Financial Statements include all subsidiaries in which the Company has the ability to exercise direct or indirect control over operating and financial policies. Intercompany transactions and balances are eliminated in consolidation. The Company, through its GPIL subsidiary, is a party to a Japanese joint venture, Rengo Riverwood Packaging, Ltd. in which it holds a 50% ownership interest that is accounted for using the equity method. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, pension benefits, retained insurable risks, slow-moving and obsolete inventory, allowance for doubtful accounts, useful lives for depreciation and amortization, impairment testing of goodwill and long-lived assets, fair values related to acquisition accounting, fair value of derivative financial instruments, share based compensation, deferred income tax assets and potential income tax assessments, and loss contingencies. Cash and Cash Equivalents Cash and cash equivalents include bank deposits and other marketable securities that are highly liquid with maturities of three months or less. Accounts Receivable and Allowances Accounts receivable are stated at the amount owed by the customer, net of an allowance for estimated uncollectible accounts, returns and allowances, and cash discounts. The allowance for doubtful accounts is estimated based on historical experience, current economic conditions and the creditworthiness of customers. Receivables are charged to the allowance when determined to be no longer collectible. The Company has entered into agreements to sell, on a revolving basis, certain trade accounts receivable to third party financial institutions. Transfers under these agreements meet the requirements to be accounted for as sales in accordance with the Transfers and Servicing topic of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification (the "Codification"). The loss on sale is not material and is included in Other (Income) Expense, Net line item on the Condensed Consolidated Statement of Operations. The following table summarizes the activity under these programs for the year ended December 31, 2021 and 2020, respectively: Year Ended December 31, In millions 2021 2020 Receivables Sold and Derecognized $ 2,947 $ 2,850 Proceeds Collected on Behalf of Financial Institutions 2,970 2,787 Net Proceeds (Paid to) Received From Financial Institutions (6) 55 Deferred Purchase Price at December 31 (a) 4 5 Pledged Receivables at December 31 180 201 (a) Included in Other Current Assets on the Condensed Consolidated Balance Sheet and represents a beneficial interest in the receivables sold to the financial institutions, which is a Level 3 fair value measure. The Company participates in supply chain financing arrangements offered by certain customers and has entered into various factoring arrangements that also qualify for sale accounting in accordance with the Transfers and Servicing topic of the FASB Codification. For the years ended December 31, 2021 and 2020, the Company sold receivables of $693 million and $368 million respectively, related to these factoring arrangements. Receivables sold under all programs subject to continuing involvement, which consists principally of collection services, were $613 million and $621 million as of December 31, 2021 and 2020, respectively. Concentration of Credit Risk The Company’s cash, cash equivalents, and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents are placed with financial institutions that management believes are of high credit quality. Accounts receivable are derived from revenue earned from customers located in the U.S. and internationally and generally do not require collateral. For the years ended December 31, 2021, 2020, and 2019, no customer accounted for more than 10% of net sales. Inventories Inventories are stated at the lower of cost and net realizable value with cost determined based on standard (which approximates actual), average or actual cost. Work in progress and finished goods inventories are valued at the cost of raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) as incurred and an applicable portion of manufacturing overhead. Inventories are stated net of an allowance for slow-moving and obsolete inventory. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Betterments, renewals and extraordinary repairs that extend the life of the asset are capitalized; other repairs and maintenance charges are expensed as incurred. The Company’s cost and related accumulated depreciation applicable to assets retired or sold are removed from the accounts and the gain or loss on disposition is included in income from operations. Interest is capitalized on assets under construction for one year or longer with an estimated spending of $1 million or more. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life. Capitalized interest was $14 million, $7 million and $3 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company assesses its long-lived assets, including certain identifiable intangibles, for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. To analyze recoverability, the Company projects future cash flows, undiscounted and before interest, over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment would be recognized, resulting in a write-down of assets with a corresponding charge to earnings. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. The Company assesses the appropriateness of the useful life of its long-lived assets periodically. Depreciation and Amortization Depreciation is computed using the straight-line method based on the following estimated useful lives of the related assets: Buildings 40 years Land improvements 15 years Machinery and equipment 3 to 40 years Furniture and fixtures 10 years Automobiles, trucks and tractors 3 to 5 years Depreciation expense, including the depreciation expense of assets under finance leases, for 2021, 2020 and 2019 was $420 million, $414 million and $388 million, respectively. Intangible Assets Intangible assets with a determinable life are amortized on a straight-line or accelerated basis over their useful lives. The amortization expense for each intangible asset is recorded in the Consolidated Statements of Operations according to the nature of that asset. Goodwill is the Company’s only intangible asset not subject to amortization. The following table displays the intangible assets that continue to be subject to amortization and accumulated amortization expense as of December 31, 2021 and 2020: December 31, 2021 December 31, 2020 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Amortizable Intangible Assets: Customer Relationships (a) $ 1,462 $ (621) $ 841 $ 965 $ (556) $ 409 Patents, Trademarks, Licenses, and Leases 140 (113) 27 141 (113) 28 Total $ 1,602 $ (734) $ 868 $ 1,106 $ (669) $ 437 (a) Please see "Note 4- Business Combinations" for the intangibles acquired with the AR Packaging acquisition. The Company recorded amortization expense for the years ended December 31, 2021, 2020 and 2019 of $69 million, $62 million and $59 million, respectively. The Company expects amortization expense for the next five consecutive years to be approximately as follows: $95 million, $92 million, $90 million, $86 million, and $86 million. Goodwill The Company tests goodwill for impairment annually as of October 1, as well as whenever events or changes in circumstances suggest that the estimated fair value of a reporting unit may no longer exceed its carrying amount. The Company tests goodwill for impairment at the reporting unit level, which is an operating segment or a level below an operating segment, which is referred to as a component. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and management regularly reviews the operating results of that component. Two or more components of an operating segment are aggregated and deemed a single reporting unit if the components have similar economic characteristics. Potential goodwill impairment is measured at the reporting unit level by comparing the reporting unit’s carrying amount (including goodwill), to the fair value of the reporting unit. When performing the quantitative analysis, the estimated fair value of each reporting unit is determined by utilizing a discounted cash flow analysis based on the Company’s forecasts, discounted using a weighted average cost of capital and market indicators of terminal year cash flows based upon a multiple of EBITDA. If the carrying amount of a reporting unit exceeds its estimated fair value, goodwill is considered impaired. In determining fair value, management relies on and considers a number of factors, including but not limited to, future operating results, business plans, economic projections of revenues and operating margins, forecasts including future cash flows, and market data and analysis, including market capitalization. The assumptions used are based on what a hypothetical market participant would use in estimating fair value. Fair value determinations are sensitive to changes in the factors described above. There are inherent uncertainties related to these factors and judgments in applying them to the analysis of goodwill impairment. Periodically, the Company may perform a qualitative impairment analysis of goodwill associated with each of its reporting units to determine if it is more likely than not that the carrying value of a reporting unit exceeded its fair value. However, the Company performed a quantitative impairment test as of October 1, 2021, and concluded goodwill was not impaired for any of its reporting units. The following is a rollforward of goodwill by reportable segment: In millions Paperboard Mills Americas Paperboard Packaging Europe Paperboard Packaging Corporate/Other (a) Total Balance at December 31, 2019 $ 507 $ 897 $ 60 $ 14 $ 1,478 Acquisition of Businesses — — — — — Foreign Currency Effects (1) 3 (1) (1) — Balance at December 31, 2020 $ 506 $ 900 $ 59 $ 13 $ 1,478 Acquisition of Businesses — 68 475 — 543 Foreign Currency Effects — — (6) — (6) Balance at December 31, 2021 $ 506 $ 968 $ 528 $ 13 $ 2,015 (a) Includes Australia operating segment. Retained Insurable Risks It is the Company’s policy to self-insure or fund a portion of certain expected losses related to group health benefits and workers’ compensation claims. Provisions for expected losses are recorded based on the Company’s estimates, on an undiscounted basis, of the aggregate liabilities for known claims and estimated claims incurred but not reported. Asset Retirement Obligations Asset retirement obligations are accounted for in accordance with the provisions of the Asset Retirement and Environmental Obligations topic of the FASB Codification. A liability and asset are recorded equal to the present value of the estimated costs associated with the retirement of long-lived assets where a legal or contractual obligation exists and the liability can be reasonably estimated. The liability is accreted over time and the asset is depreciated over the remaining life of the asset. Upon settlement of the liability, the Company will recognize a gain or loss for any difference between the settlement amount and the liability recorded. Asset retirement obligations with indeterminate settlement dates are not recorded until such time that a reasonable estimate may be made. The Company's asset retirement obligations consist primarily of landfill closure and post-closure costs at certain of our mills. At December 31, 2021 and 2020, the Company had liabilities of $12 million and $11 million, respectively. The liabilities are primarily reflected as Other Noncurrent Liabilities in the Company's Consolidated Balance Sheets. International Currency The functional currency of the international subsidiaries is usually the local currency for the country in which the subsidiaries own their primary assets. The translation of the applicable currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. Any related translation adjustments are recorded directly to a separate component of Shareholders’ Equity, unless there is a sale or substantially complete liquidation of the underlying foreign investments. Gains and losses on foreign currency transactions are included in Other Expense, Net for the period in which the exchange rate changes. The Company pursues a currency hedging program which utilizes derivatives to reduce the impact of foreign currency exchange fluctuations on its consolidated financial results. Under this program, the Company has entered into forward exchange contracts in the normal course of business to hedge certain foreign currency denominated transactions. Realized and unrealized gains and losses on these forward contracts are included in the measurement of the basis of the related foreign currency transaction when recorded. Revenue Recognition The Company has two primary activities, manufacturing and converting paperboard, from which it generates revenue from contracts with customers. Revenue is disaggregated primarily by geography and type of activity as further explained in " Note 15 - Business Segment and Geographic Area Information. " All reportable segments and the Australia and Pacific Rim operating segments recognize revenue under the same method, allocate transaction price using similar methods, and have similar economic factors impacting the uncertainty of revenue and related cash flows. Revenue is recognized on the Company's annual and multi-year supply contracts when the Company satisfies the performance obligation by transferring control over the product or service to a customer, which is generally based on shipping terms and passage of title under the point-in-time method of recognition. For the years ended December 31, 2021, 2020 and 2019, the Company recognized $7,131 million, $6,537 million and $6,141 million, respectively, of revenue from contracts with customers. The transaction price allocated to each performance obligation consists of the stand-alone selling price, estimates of rebates and other sales or contract renewal incentives, and cash discounts and sales returns ("Variable Consideration") and excludes sales tax. Estimates are made for Variable Consideration based on contract terms and historical experience of actual results and are applied to the performance obligations as they are satisfied. Purchases by the Company’s principal customers are manufactured and shipped with minimal lead time, therefore performance obligations are generally satisfied shortly after manufacturing and shipment. The Company uses standard payment terms that are consistent with industry practice. The Company's contract assets consist primarily of contract renewal incentive payments to customers which are amortized over the period in which performance obligations related to the contract renewal are satisfied. As of December 31, 2021 and 2020, contract assets were $17 million and $15 million, respectively. The Company's contract liabilities consist principally of rebates, and as of December 31, 2021 and 2020 were $61 million and $56 million, respectively. The Company did not have a material amount relating to backlog orders at December 31, 2021 or 2020. Shipping and Handling The Company includes shipping and handling costs in Cost of Sales. Research and Development Research and development costs, which relate primarily to the development and design of new packaging machines and products and are recorded as a component of Selling, General and Administrative expenses, are expensed as incurred. Expenses for the years ended December 31, 2021, 2020 and 2019 were $10 million, $10 million and $9 million, respectively. Business Combinations, Shutdown and Other Special Charges, and Exit Activities, Net The following table summarizes the transactions recorded in Business Combinations, Shutdown and Other Special Charges, and Exit Activities, Net in the Consolidated Statements of Operations for the year ended December 31: In millions 2021 2020 2019 Charges Associated with Business Combinations (a) $ 84 $ (2) $ 4 Shutdown and Other Special Charges 33 38 24 Exit Activities (b) 21 25 10 Total $ 138 $ 61 $ 38 (a) Includes $48 million of unrealized losses resulting from deal contingent foreign exchange forward contracts from the AR Packaging acquisition (see "Note 11- Fair Value Measurement" ).

Charges associated with these projects are included in Exit Activities in the table above. For more information, see "Note 18 - Exit Activities." On April 1, 2020, the Company acquired the Consumer Packaging Group business from Greif, Inc. ("Greif"), a leader in industrial packaging products and services. The acquisition included seven converting plants across the United States and will allow the company to increase its mill-to-converting plant integration over time. The Company paid approximately $80 million using existing cash and borrowings under its revolving credit facility. The costs associated with this acquisition are included in Charges Associated with Business Combinations in the table above. During the second quarter of 2021, the acquisition accounting for Greif was finalized. For more information, see "Note 4 - Business Combinations."

The acquisition included two converting plants located in Auburn, Indiana and Elgin, Illinois (included in the Americas Paperboard Packaging reportable segment) and one CRB paperboard mill located in White Pigeon, Michigan (included in the Paperboard Mills reportable segment). Share Repurchases and Dividends On January 28, 2019, GPHC's board of directors authorized an additional share repurchase program to allow GPHC to purchase up to $500 million of GPHC's issued and outstanding shares of common stock through open market purchases, privately negotiated transactions and Rule 10b5-1 plans (the "2019 share repurchase program"). A previous $250 million share repurchase program was authorized on January 10, 2017 (the "2017 share repurchase program"). Share repurchases are reflected as a reduction of common stock for the par value of the shares, with any excess of share repurchase price over par value allocated between capital in excess of par value and accumulated deficit. The Company did not repurchase any shares of its common stock under the 2019 share repurchase program for the year ended December 31, 2021. The following presents GPHC's share repurchases for the years ended December 31, 2020 and 2019: Amount repurchased in millions Amount Repurchased Number of Shares Repurchased Average Price 2020 $ 316 23,420,010 $ 13.48 2019 $ 128 10,191,257 (a) $ 12.55 (a) Includes 7,400,171 shares under the 2017 share repurchase program thereby completing that program.

Adoption of New Accounting Standards In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . This amendment modifies ASC 740 to simplify the accounting for income taxes. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this new guidance during the three months ended March 31, 2021. The Company’s adoption did not result in any changes in accounting principle upon transition and the impact to the Company’s overall financial statements is immaterial. Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . This standard provides temporary optional expedients and exceptions for applying GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). The ASU can be adopted after its issuance date through December 31, 2022. The Company is currently evaluating the impact of this new accounting guidance. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities . Under the new guidance, the acquirer should determine what contract assets and/or contract liabilities it would have recorded under ASC 606 as of the acquisition date, as if the acquirer had entered into the original contract at the same date and on the same terms as the acquiree. The recognition and measurement of those contract assets and contract liabilities will likely be comparable to what the acquiree has recorded on its books under ASC 606 as of the acquisition date. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in an interim period, for any period for which financial statements have not yet been issued. However, adoption in an interim period other than the first fiscal quarter requires an entity to apply the new guidance to all prior business combinations that have occurred since the beginning of the annual period in which the new guidance is adopted. The Company is currently evaluating the adoption date of ASU 2021-08 and the impact, if any, adoption will have on its financial position and results of operations.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS The Company accounts for acquisitions as business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations (“ASC 805”). Americraft On July 1, 2021, the Company acquired substantially all of the assets of Americraft. The Company paid approximately $292 million, using existing cash and borrowings under its revolving credit facility. The acquisition included seven converting plants across the United States. The purchase price for Americraft has been allocated to assets acquired and liabilities assumed based on the fair values as of the acquisition date and is subject to adjustments in subsequent periods as management finalizes its purchase price allocation, including the third-party valuations. Tangible assets and liabilities were valued as of the acquisition date using the indirect and direct methods of the cost approach and intangible assets were valued using a discounted cash flow analysis, which represents a Level 3 measurement. Management believes that the purchase price attributable to goodwill represents the benefits expected as the acquisition was made to continue to expand its product offering, to integrate paperboard from the Company's mills and to further optimize the Company's supply chain footprint. The assigned goodwill, which is deductible for tax purposes, is reported within the Americas Paperboard Packaging reportable segment. The preliminary purchase price allocation, including immaterial measurement period adjustments, is as follows as of December 31, 2021: In millions Amounts Recognized as of Acquisition Date (as adjusted) Purchase Price $ 292 Receivables, Net 22 Inventories 37 Property, Plant and Equipment 122 Intangible Assets (a) 54 Other Assets 1 Total Assets Acquired 236 Current Liabilities 12 Total Liabilities Assumed 12 Net Assets Acquired 224 Goodwill 68 Total Estimated Fair Value of Net Assets Acquired $ 292 (a) Intangible Assets primarily consists of Customer Relationships with a weighted average life of approximately 15 years. The Company included the results of operations of this acquisition in its Consolidated Statements of Income from the closing date of the acquisition. During 2021, Net Sales and Income from Operations for the Americraft acquisition were $108 million and $4 million, respectively. AR Packaging On November 1, 2021, the Company completed the acquisition of AR Packaging Group AB, Europe's second largest producer of fiber-based consumer packaging, by acquiring all the AR Packaging Group AB shares that were issued and outstanding as of the date of acquisition. The acquisition included 30 converting plants in 13 countries and enhances the Company’s global scale, innovation capabilities, and value proposition for customers throughout Europe and bordering regions. The total cash consideration for the AR Acquisition was $1,412 million net of cash acquired of $75 million, paid in Euros through the use of deal contingent, foreign exchange forward contracts, purchased through the use of available borrowing capacity on the Company’s Senior Secured Revolving Credit Facilities and the $400 million Incremental Facility Amendment to the Fourth Amended and Restated Credit Agreement. For more information, see "Note 5 - Debt." The purchase price was allocated to the assets acquired and liabilities assumed based on the estimated fair values as of the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill, none of which is expected to be deductible for tax purposes, and will be reported within the Europe reportable segment. The allocation of purchase price shown below remains preliminary and is subject to further adjustment, pending additional refinement and final completion of valuations, including but not limited to valuations of property and equipment, customer relationships and other intangible assets, and deferred tax liabilities. Goodwill is primarily attributed to synergies from future expected economic benefits, including enhanced revenue growth from expanded capabilities and geographic presence as well as substantial cost savings from duplicative overhead, streamlined operations and enhanced operational efficiency. In millions Amounts Recognized as of Acquisition Date (a) Total Purchase Consideration $ 1,487 Cash Acquired 75 Receivables, Net 212 Inventories 166 Other Current Assets 12 Property, Plant and Equipment (b) 529 Intangible Assets (c) 447 Other Assets 76 Total Assets Acquired 1,517 Accounts Payable 109 Compensation and Employee Benefits 12 Other Accrued Liabilities 101 Short-Term Debt and Current Portion of Long-Term Debt 9 Long-Term Debt 17 Deferred Income Tax Liabilities 164 Accrued Pension and Postretirement Benefits 50 Other Noncurrent Liabilities 41 Noncontrolling Interests 2 Total Liabilities Assumed 505 Net Assets Acquired 1,012 Goodwill 475 Total Estimated Fair Value of Net Assets Acquired $ 1,487 (a) The amounts were translated from Euro to USD using the rate at the acquisition date of 1.1539. (b) Property, Plant and Equipment primarily consists of Machinery and Equipment of $371 million with a weighted average life of approximately 12 years. (c) Intangible Assets primarily consists of Customer Relationships of $439 million with a weighted average life of approximately 15 years. The above fair values of assets acquired and liabilities assumed are preliminary and are based on the information that was available as of the reporting date. The fair values of the tangible assets acquired and liabilities assumed were preliminarily determined using the income and cost approaches. In many cases, the determination of the fair values required estimates about discount rates, future expected cash flows and other future events that are judgmental and subject to change. The fair value measurements were primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement of the fair value hierarchy as defined in ASC 820, Fair Value Measurements (“ASC 820”). Intangible assets consisting of customer relationships, technology, and trade names were valued using the discounted cash flow analysis. The significant assumptions used to estimate the value of the customer relationships intangible assets included the discount rate, annual revenue growth rates, customer attrition rates, projected operating expenses, projected EBITDA margins, tax rate, depreciation, and contributory asset charge. The Company believes that the information provides a reasonable basis for estimating the fair values of the acquired assets and assumed liabilities, but the potential for measurement period adjustments exists based on the Company’s continuing review of matters related to the acquisition. The Company expects to complete the purchase price allocation as soon as practicable, but no later than one year from the acquisition date. Since the acquisition date, the results of operations for AR Packaging of $176 million of revenue and $8 million of operating income have been included within the consolidated statements of income for the twelve months ended December 31, 2021. The following unaudited pro forma consolidated financial information for the twelve months ended December 31, 2021 combines the results of the Company for the year ended December 31, 2021 and the unaudited results of AR Packaging for the corresponding period through the Acquisition Date, November 1, 2021. The following unaudited pro forma consolidated financial information for the twelve months ended December 31, 2020 combines the results of the Company for fiscal 2020 and the unaudited results of AR Packaging for the corresponding period. The unaudited pro forma consolidated financial information assumes that the Acquisition, which closed on November 1, 2021, was completed on January 1, 2020 (the first day of fiscal 2020). The pro forma consolidated financial information has been calculated after applying the Company’s accounting policies and includes adjustments for amortization expense of acquired intangible assets, fair value adjustments for acquired inventory, property, plant and equipment and long-term debt. For fiscal 2020, non-recurring pro forma adjustments directly attributable to the Acquisition included pre-tax amounts of $16 million related to the acquisition accounting effect of inventories acquired and $74 million of transaction costs. The $74 million of transaction costs include the $48 million loss on the forward contracts that the Company used to partially fund the acquisition of AR Packaging. These costs will not effect the Company's income statement beyond 12 months after the acquisition date. These pro forma results have been prepared for comparative purposes only and do not purport to be indicative of the operating results of the Company that would have been achieved had the Acquisition actually taken place on January 1, 2020. In addition, these results are not intended to be a projection of future results and do not reflect events that may occur after the Acquisition, including but not limited to revenue enhancements, cost savings or operating synergies that the combined Company may achieve as a result of the Acquisition. Pro Forma Twelve Months Ended (unaudited) In millions December 31, 2021 December 31, 2020 Revenue $ 8,096 $ 7,562 Net Income (Loss) $ 293 $ 94 2020 On January 31, 2020, the Company acquired a folding carton facility from Quad, a commercial printing company. The converting facility is located in Omaha, Nebraska, close to many of the Company's existing food and beverage customers. The Company paid approximately $41 million using existing cash and borrowings under its revolving credit facility. The purchase price was allocated to assets acquired and liabilities assumed based on the estimated fair values as of the acquisition date. The Company recorded $5 million related to identifiable intangible assets (customer relationships with useful lives of fifteen years), $43 million related to net tangible assets (primarily working capital, land/buildings and equipment) and a bargain purchase gain of $7 million as the net fair value of assets acquired and liabilities assumed was greater than the purchase price. During 2020, Net Sales and Loss from Operations for the Quad acquisition were $79 million and $1.0 million, respectively. During the first quarter of 2021, the acquisition accounting for Quad was finalized. On April 1, 2020, the Company acquired the Consumer Packaging Group business from Greif, Inc., a leader in industrial packaging products and services. The acquisition included seven converting plants across the United States and will allow the Company to increase its mill-to-converting plant integration over time. The Company paid $80 million using existing cash and borrowings under its revolving credit facility. The purchase price was allocated to assets acquired and liabilities assumed based on the estimated fair values as of the acquisition date. The Company recorded $13 million related to identifiable intangible assets (customer relationships with useful lives of fifteen years) and $67 million related to net tangible assets (primarily working capital, land/buildings and equipment). During 2020, Net Sales and Loss from Operations for the Greif acquisition were $165 million and $14 million, respectively. During the second quarter of 2021, the acquisition accounting for the Greif was finalized. 2019 On August 1, 2019, the Company completed the acquisition of Artistic, a diversified producer of folding cartons and CRB. The acquisition included two converting plants located in Auburn, Indiana and Elgin, Illinois and one CRB paperboard mill located in White Pigeon, Michigan. The Company paid $53 million using existing cash and borrowings under its revolving credit facility. Management believes that the purchase price attributable to goodwill represents the benefits expected as the acquisition was made to continue to integrate paperboard from the Company’s mills, to expand its product offering and to further optimize the Company’s supply chain footprint. During 2019, Net Sales and Income from Operations from the Artistic acquisition were $31 million and $2 million, respectively.

On March 8, 2021, GPIL completed a private offering of $400 million aggregate principal amount of its 0.821% Senior Secured Notes due 2024 and $400 million aggregate principal amount of its 1.512% Senior Secured Notes due 2026. The net proceeds were used by the Company to repay a portion of the outstanding borrowings under GPIL's term loan credit facilities, which is under its senior secured credit facility. On April 1, 2021, GPIL entered into a Fourth Amended and Restated Credit Agreement (the “Fourth Amended and Restated Credit Agreement”) to extend the maturity date of certain of its senior secured term loan facilities and senior secured revolving credit facilities and to amend certain other terms of the agreement, including revised debt covenants and collateral requirements. Under the terms of the agreement, $975 million of the Company’s senior secured term loan facilities remains outstanding. The Company added approximately $400 million to its senior secured revolving credit facilities. $550 million of the senior secured term loan facilities and all of the senior secured revolving credit facility loans continue to bear interest at a floating rate per annum ranging from LIBOR plus 1.25% to LIBOR plus 2.00%, determined using a pricing grid based upon the Company’s consolidated total leverage ratio from time to time, and the maturity for these loans were extended from January 1, 2023 to April 1, 2026. $425 million of the senior secured term loan facilities, which is a Farm Credit System incremental term loan (the “Incremental Term A-2 Facility Amendment”) continue to bear interest at a fixed rate per annum equal to 2.67% and matures on their originally scheduled maturity date of January 14, 2028. As long as the Incremental Term A-2 Facility Amendment is outstanding, GPIL will be eligible to receive an annual patronage credit from the participating banks, which will be paid in cash and stock in the lead member bank. Patronage payable each year is variable and based on the individual financial performance of each of the member banks then participating in the loan. On July 22, 2021, GPIL entered into an Incremental Facility Amendment to the Fourth Amended and Restated Credit Agreement for a second Farm Credit System incremental term loan (the “Incremental Term A-3 Facility”). The Incremental Term A-3 Facility is a senior secured term loan in the aggregate principal amount of $250 million maturing on July 22, 2028. The Incremental Term A-3 Facility bears interest at a floating rate ranging from LIBOR plus 1.50% to LIBOR plus 2.25%, determined using a pricing grid based upon GPIL’s consolidated leverage ratio. As long as the Incremental Term A-3 Facility is outstanding, GPIL will be eligible to receive an annual patronage credit from the participating banks, which will be paid in cash and stock in the lead member bank. Patronage payable each year is variable and based on the individual financial performance of each of the member banks then participating in the loan. The Incremental Term A-3 Facility is governed by the same covenants as are set forth in the Fourth Amended and Restated Credit Agreement and is secured by a first priority lien and security interest in certain assets of GPIL. On July 23, 2021, GPIL entered into Amendment No. 1 to the Fourth Amended and Restated Credit Agreement and the Fourth Amended and Restated Guarantee and Collateral Agreement and Incremental Facility Amendment (the “First Amendment”). The First Amendment provided for a delayed draw term loan facility in an aggregate amount of €210 million and a €25 million increase to the existing Euro-denominated revolving credit facility. The new term loan facility was drawn on October 29, 2021, and bears interest at a floating rate ranging from LIBOR plus 1.125% to LIBOR plus 1.75%, determined using a pricing grid based upon GPIL’s consolidated total leverage ratio from time to time. The new term loan facility is governed by the same covenants as set forth in the Fourth Amended and Restated Credit Agreement and is secured by a first priority lien and security interest in certain assets of GPIL. On September 29, 2021, GPIL completed a $100 million tax-exempt green bond transaction through the Michigan Strategic Fund’s Private Activity Bond Program (the “Green Bonds”). The Green Bonds are special limited obligations of the Michigan Strategic Fund, as issuer, payable from and secured by a pledge of payments to be made by GPIL under a loan agreement between the Michigan Strategic Fund and GPIL. The Green Bonds mature in 2061 and include a mandatory purchase on October 1, 2026. The Green Bonds were issued at a price of 110.99% and bear interest at an annual rate of 4.0%. The equivalent yield is 1.70%. The net proceeds of $109.5 million were used to fund a portion of its spend on the CRB platform optimization project that includes the construction of a new CRB machine at its Kalamazoo, Michigan mill. The bonds have been designated as Green Bonds primarily because the proceeds were used to finance a solid waste disposal/recycling facility resulting in diversion of waste from landfills. In addition to the solid waste recycling aspect, the project improves the environmental footprint of its CRB mill system through expected reductions in water usage, energy consumption and greenhouse gas emissions. On October 6, 2021, GPIL entered into a $400 million Incremental Facility Amendment to the Fourth Amended and Restated Credit Agreement (the "Incremental Term A-4 Facility"). The Incremental Term A-4 Facility has a delayed draw feature, and the Company funded the new term loan on October 29, 2021. The Incremental Term A-4 Facility was collateralized by the same assets as GPIL’s Senior Secured Facilities on a pari passu basis. The Incremental Term A-4 Facility bore interest at a floating rate per annum equal to the Base Rate, the Euro currency Rate plus 0.875%, or the Daily Floating LIBOR Rate plus 0.875%, as selected by the Company. The loan was repaid on November 19, 2021 with the proceeds from the 3.75% senior unsecured notes due 2030. On November 19, 2021, GPIL completed a private offering of $400 million aggregate principal amount of 3.750% senior unsecured notes due 2030 (the “Dollar Notes”) and €290 million aggregate principal amount of 2.625% senior unsecured notes due 2029 (the “Euro Notes”). The net proceeds of the Dollar Notes were used to repay in full the term loan borrowed under the Incremental Term A-4 Loan, which was under its senior secured credit facility. The net proceeds of the Euro Notes were used to repay revolver borrowings outstanding under its senior secured credit facility. 2020 On March 6, 2020, GPIL completed a private offering of $450 million aggregate principal amount of its senior unsecured notes due 2028. The Senior Notes bear interest at an annual rate of 3.50%. The net proceeds were used by the Company to repay a portion of the outstanding borrowings under GPIL's revolving credit facility, which is under its senior secured credit facility. On August 28, 2020, GPIL completed a private offering of $350 million aggregate principal amount of its senior unsecured notes due 2029. The Senior Notes bear interest at an annual rate of 3.50%. The net proceeds were used by the Company to repay a portion of the outstanding borrowings under GPIL's revolving credit facility, which is under its senior secured credit facility.

Leases [Abstract]
Leases	LEASES The Company determines if a contract is or contains a lease at inception. The Company has operating and finance leases for warehouses, corporate and regional offices, and machinery and equipment. The Company enters into lease contracts ranging from one of three many of which include options to extend in various increments. Variable lease costs consist primarily of variable warehousing costs, common area maintenance, taxes, and insurance. The Company’s leases do not have any significant residual value guarantees or restrictive covenants. As the implicit rate is not readily determinable for most of the Company’s leases agreements, the Company uses an estimated incremental borrowing rate to determine the initial present value of lease payments. These discount rates for leases are calculated using the Company's credit spread adjusted for current market factors, including fixed rate swaps, LIBOR, and foreign currency rates.

Share-based Payment Arrangement [Abstract]
Stock Incentive Plans	STOCK INCENTIVE PLANS The Company has one active equity compensation plan from which new grants may be made, the Graphic Packaging Holding Company 2014 Omnibus Stock and Incentive Compensation Plan (the “2014 Plan”). The 2014 Plan allows for granting shares of stock, options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), restricted stock awards (“RSAs”), and other types of stock-based and cash awards. Awards under the 2014 Plan vest and expire in accordance with terms established at the time of grant. Shares issued pursuant to awards under the 2014 Plan are from GPHC’s authorized but unissued shares. Compensation costs are recognized on a straight-line basis over the requisite service period of the award and are adjusted for actual performance for performance-based awards. As of December 31, 2021, there were 11.6 million shares remaining available to be granted under the 2014 Plan. Stock Awards, Restricted Stock and Restricted Stock Units Under the 2014 Plan, all RSUs granted to employees generally vest and become payable in three years from date of grant. RSUs granted to employees generally contain some combination of service and performance objectives based on various financial targets and relative total shareholder return that must be met for the RSUs to vest. RSUs granted as deferred compensation for non-employee directors are fully vested but not payable until the distribution date elected by the director. RSAs issued to non-employee directors as part of their compensation for service on the Board are unrestricted on the grant date. Data concerning RSUs and RSAs granted during the years ended December 31 is as follows: 2021 2020 2019 RSUs — Employees 1,680,997 1,655,854 2,187,603 Weighted-average grant date fair value $ 16.14 $ 15.40 $ 12.37 Stock Awards — Board of Directors 55,055 71,160 74,760 Weighted-average grant date fair value $ 17.80 $ 13.49 $ 12.84 A summary of the changes in the number of unvested RSUs from December 31, 2018 to December 31, 2021 is presented below: RSUs Weighted Average Grant Date Fair Value Outstanding — December 31, 2018 4,460,034 $ 13.27 Granted (a) 2,187,603 12.37 Released (900,516) 12.00 Forfeited (187,729) 13.66 Performance adjustment (b) (499,702) 11.57 Outstanding — December 31, 2019 5,059,690 $ 13.27 Granted (a) 1,655,854 15.40 Released (1,415,365) 12.91 Forfeited (158,473) 14.25 Outstanding — December 31, 2020 5,141,706 $ 14.02 Granted (a) 1,680,997 16.14 Released (2,121,203) 14.88 Forfeited (359,100) 14.39 Performance adjustment (b) 587,461 15.09 Outstanding — December 31, 2021 4,929,861 $ 14.47 (a) Grant activity for all performance-based RSUs is disclosed at target. (b) Reflects the number of RSUs above and below target levels based on actual performance measured at the end of the performance period. The initial value of the service-based RSUs is based on the closing market value of GPHC’s common stock on the date of grant. The 2021 performance-based RSU grants were valued using a Monte Carlo simulation as the total shareholder return contains a market condition. RSUs are recorded in Shareholders' Equity. The unrecognized expense at December 31, 2021 is approximately $31 million and is expected to be recognized over a weighted average period of 2 years. The value of stock awards granted to the Company's directors are based on the market value of GPHC’s common stock on the date of grant. These awards are unrestricted on the date of grant. During 2021, 2020, and 2019, $27 million, $34 million and $22 million, respectively, were charged to compensation expense for stock incentive plans and is primarily included in Selling, General and Administrative expenses in the Consolidated Statements of Operations. During 2021, 2020, and 2019, RSUs with an aggregate fair value of $35 million, $23 million and $11 million, respectively, vested and were paid out. The RSUs vested and paid out in 2021 were granted primarily during 2018.

Pensions and Other Postretireme

Pensions and Other Postretirement Benefits	12 Months Ended

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits	PENSIONS AND OTHER POSTRETIREMENT BENEFITS DEFINED BENEFIT PLANS The Company maintains both defined benefit pension plans and postretirement health care plans that provide medical and life insurance coverage to eligible salaried and hourly retired employees in North America and their dependents. The Company maintains international defined benefit pension plans which are either noncontributory or contributory and are funded in accordance with applicable local laws. Pension or termination benefits are based primarily on years of service and the employees’ compensation. Currently, the North American plans are closed to newly-hired employees except as noted below. Effective July 1, 2011, the North American plans were frozen for most salaried and non-union hourly employees and replaced with a defined contribution plan. During 2018, the Company began the process of terminating its largest U.S. pension plan (the "U.S. Plan"). This included freezing the plan as of December 31, 2018 and spinning off the active participants to the plan established as part of the NACP Combination (the "NACP Plan"). The NACP Plan is open for union and non-union hourly employees of locations that were part of the NACP Combination. During the third quarter of 2019, the Company offered a lump-sum benefit option to certain participants in the U.S. Plan. Lump sum payments of $150 million were paid in the fourth quarter of 2019 and the Company recognized a non-cash settlement charge of $39 million associated with the payouts. In the first quarter of 2020, the Company, using the assets held within the pension trust, purchased a group annuity contract that transferred the remaining pension obligation under the U.S. Plan of approximately $713 million to an insurance company. The Company incurred an additional non-cash settlement charge of $154 million related to this transfer. These non-cash settlement charges relate to Net Actuarial Loss previously recognized in Accumulated Other Comprehensive Loss. As disclosed in " Note 1 - Nature of Business and Summary of Significant Accounting Policies ," during the fourth quarter of 2021, the Company acquired substantially all the shares of AR Packaging. The business combination led to the Company acquiring approximately $53 million in pension benefit obligations and $1 million in pension plan assets. Pension and Postretirement Expense The pension and postretirement expenses related to the Company’s plans consisted of the following: Pension Benefits Postretirement Benefits Year Ended December 31, In millions 2021 2020 2019 2021 2020 2019 Components of Net Periodic Cost: Service Cost $ 15 $ 15 $ 14 $ — $ 1 $ — Interest Cost 10 14 46 1 1 1 Expected Return on Plan Assets (19) (21) (55) — — — Amortization of Actuarial Loss (Gain) 5 5 10 (2) (2) (2) Net Curtailment/Settlement Loss — 154 39 — — — Net Periodic Cost (Benefit) $ 11 $ 167 $ 54 $ (1) $ — $ (1) Certain assumptions used in determining the pension and postretirement expenses were as follows: Pension Benefits Postretirement Benefits Year Ended December 31, 2021 2020 2019 2021 2020 2019 Weighted Average Assumptions: Discount Rate 2.11 % 2.69 % 4.14 % 2.52 % 3.22 % 4.29 % Rate of Increase in Future Compensation Levels 3.62 % 2.36 % 2.37 % — — — Expected Long-Term Rate of Return on Plan Assets 3.59 % 4.12 % 4.74 % — — — Initial Health Care Cost Trend Rate — — — 6.40 % 6.65 % 9.00 % Ultimate Health Care Cost Trend Rate — — — 4.50 % 4.50 % 4.50 % Ultimate Year — — — 2028 2028 2028 Funded Status The following table sets forth the funded status of the Company’s pension and postretirement plans as of December 31: Pension Benefits Postretirement Benefits In millions 2021 2020 2021 2020 Change in Benefit Obligation: Benefit Obligation at Beginning of Year $ 593 $ 1,256 $ 36 $ 36 Service Cost 15 15 — 1 Interest Cost 10 14 1 1 Net Actuarial (Gain) Loss (21) 62 (3) — Foreign Currency Exchange (4) 9 — — Settlements — (743) — — Benefits Paid (19) (20) (1) (2) Acquisition 53 — — — Benefit Obligation at End of Year $ 627 $ 593 $ 33 $ 36 Change in Plan Assets: Fair Value of Plan Assets at Beginning of Year $ 516 $ 1,172 $ — $ — Actual Return on Plan Assets 28 58 — — Employer Contributions 33 19 1 1 Foreign Currency Exchange (2) 8 — — Benefits Paid (19) (20) (1) (1) Acquisition 1 — — — Settlements — (721) — — Fair Value of Plan Assets at End of Year $ 557 $ 516 $ — $ — Plan Assets Less than Projected Benefit Obligation $ (70) $ (77) $ (33) $ (36) Amounts Recognized in the Consolidated Balance Sheets Consist of: Pension Assets $ 43 $ 21 $ — $ — Accrued Pension and Postretirement Benefits Liability — Current $ (4) $ (2) $ (3) $ (2) Accrued Pension and Postretirement Benefits Liability — Noncurrent $ (109) $ (96) $ (30) $ (34) Accumulated Other Comprehensive Income: Net Actuarial Loss (Gain) $ 71 $ 106 $ (1) $ (1) Prior Service Cost (Credit) $ 4 $ 4 $ (16) $ (15) Weighted Average Calculations: Discount Rate 2.46 % 2.11 % 2.92 % 2.52 % Rates of Increase in Future Compensation Levels 1.80 % 3.62 % — — Initial Health Care Cost Trend Rate — — 6.15 % 6.40 % Ultimate Health Care Cost Trend Rate — — 4.50 % 4.50 % Ultimate Year — — 2031 2028 The Company determined pension expense using both the fair value of assets and a calculated value that averages gains and losses over a period of years. Investment gains or losses represent the difference between the expected and actual return on assets. As of December 31, 2021, the net actuarial loss was $71 million. These net losses may increase future pension expense if not offset by (i) actual investment returns that exceed the assumed investment returns, or (ii) other factors, including reduced pension liabilities arising from higher discount rates used to calculate pension obligations, or (iii) other actuarial gains, including whether such accumulated actuarial losses at each measurement date exceed the “corridor” determined under the Compensation — Retirement Benefits topic of the FASB Codification. For the largest plan, the actuarial loss is amortized over the average remaining service period of employees expected to receive benefits. The discount rate used to determine the present value of future pension obligations at December 31, 2021 was based on a yield curve constructed from a portfolio of high-quality corporate debt securities with maturities ranging from 1 year to 30 years. Each year’s expected future benefit payments were discounted to their present value at the spot yield curve rate thereby generating the overall discount rate for the Company’s pension obligations. The weighted average discount rate used to determine the pension obligations was 2.46% and 2.11% in 2021 and 2020, respectively. The pension net actuarial gain of $21 million was primarily due to changes in the discount rate of $20 million. The weighted average discount rate at December 31, 2021 was 2.46% compared to 2.11% at December 31, 2020. Accumulated Benefit Obligation The accumulated benefit obligation, (“ABO”), for all defined benefit pension plans was $621 million and $588 million at December 31, 2021 and 2020, respectively. The projected benefit obligation (“PBO”) and fair value of plan assets where the PBO exceeded plan assets were $383 million and $361 million, respectively. The ABO and fair value of plan assets where the ABO exceeded plan assets were $378 million and $357 million, respectively. Employer Contributions The Company made contributions of $33 million and $19 million to its pension plans during 2021 and 2020, respectively. During 2021, the Company made a $14 million contribution to its remaining U.S. defined benefit plan by effectively utilizing a portion of the excess balance related to the terminated U.S. defined benefit plan. For 2022, the Company expects to make a contribution of $6 million by utilizing the excess balance. Excluding this $6 million contribution, for 2022, the Company expects to make contributions in the range of $10 million to $20 million to its pension plan. The Company also made postretirement health care benefit payments of $1 million during 2021 and 2020. For 2022, the Company expects to make approximately $2 million contributions to its postretirement health care plans. Pension Assets The Company’s overall investment strategy is to achieve a mix of investments for long-term growth and near-term benefit payments through diversification of asset types, fund strategies and fund managers. Investment risk is measured on an on-going basis through annual liability measurements, periodic asset/liability studies, and quarterly investment portfolio reviews. The plans invest in the following major asset categories: cash, equity securities, fixed income securities, real estate and diversified growth funds. At December 31, 2021 and 2020, pension investments did not include any direct investments in the Company’s stock or the Company’s debt. The Company implemented a de-risking or liability driven investment strategy for its U.S. and U.K. pension plans. This strategy moved assets from return seeking (equities) to investments that mirror the underlying benefit obligations (fixed income). The weighted average allocation of plan assets and the target allocation by asset category is as follows: Target 2021 2020 Cash 1 % 3 % 1 % Equity Securities 24 26 24 Fixed Income Securities 48 46 62 Other Investments 27 25 13 Total 100 % 100 % 100 % The plans’ investment in equity securities primarily includes investments in U.S. and international companies of varying sizes and industries. The strategy of these investments is to 1) exceed the return of an appropriate benchmark for such equity classes and 2) through diversification, reduce volatility while enhancing long term real growth. The plans’ investment in fixed income securities includes government bonds, investment grade bonds and non-investment grade bonds across a broad and diverse issuer base. The strategy of these investments is to provide income and stability and to diversify the fixed income exposure of the plan assets, thereby reducing volatility. The Company’s approach to developing the expected long-term rate of return on pension plan assets is based on fair values and combines an analysis of historical investment performance by asset class, the Company’s investment guidelines and current and expected economic fundamentals. The following tables set forth, by category and within the fair value hierarchy, the fair value of the Company’s pension assets at December 31, 2021 and 2020: Fair Value Measurements at December 31, 2021 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Asset Value at December 31, 2021 (b) Asset Category: Cash $ 19 $ 17 $ 1 $ — $ 1 Equity Securities: Domestic 140 5 13 — 122 Foreign 8 8 — — — Fixed Income Securities 254 19 234 1 — Other Investments: Real estate 7 — 7 — — Liability Driven Investment 90 31 59 — — Diversified growth fund (a) 39 — 7 32 — Total $ 557 $ 80 $ 321 $ 33 $ 123 Fair Value Measurements at December 31, 2020 In millions Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Asset Value at December 31, 2020 (b) Asset Category: Cash $ 6 $ — $ 2 $ — $ 4 Equity Securities: Domestic 118 5 12 — 101 Foreign 7 7 — — — Fixed Income Securities 319 19 300 — — Other Investments: Real estate 23 — 9 14 — Diversified growth fund (a) 43 — 43 — — Total $ 516 $ 31 $ 366 $ 14 $ 105 (a) The fund invests in a combination of traditional investments (equities, bonds, and foreign exchange), seeking to achieve returns through active asset allocation over a three (b) Investments that are measured at net asset value (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy.

Estimated liabilities have been established related to the partial or complete withdrawal from certain multi-employment benefit plans for facilities that have been closed. During the second quarter of 2020, the Company increased its estimated withdrawal liability for these plans by $12 million. During the fourth quarter of 2020, the Company entered into a settlement agreement with one of its closed multi-employment benefit plans and recorded a $4 million reduction in its estimated withdrawal liability for this plan. Under the terms of this settlement agreement, the Company paid $17 million in the first quarter of 2021. At December 31, 2021 and December 31, 2020, the Company has withdrawal liabilities of $19 million and $37 million, respectively, related to these plans, which is recorded as Compensation and Employee Benefits and Other Noncurrent Liabilities in the Company's Consolidated Balance Sheets, which represents the Company's best estimate of the expected withdrawal liability.

As a result of decreases in the minority partner's interest during 2021 and 2020, the difference between the effective tax rate and the statutory tax also declined. In addition, during 2021, the Company recognized tax expense of approximately $4 million related to the remeasurement of deferred tax assets for executive compensation as a result of IP’s exchange of its remaining shares in GPIP during the period and approximately $3 million related to the remeasurement of its net deferred tax liability for its UK subsidiaries due to the statutory tax rate increase enacted during the second quarter. During 2020, the Company recognized a tax benefit of approximately $8 million attributable to the release of a valuation allowance recorded against the net deferred tax assets of two of its Canadian subsidiaries as a result of internal restructuring. The Company also recognized a tax benefit related to updates to is 2019 financial statement income tax calculations of approximately $2 million primarily due to new guidance in final U.S. Treasury Regulations issued during 2020. During 2019, the Company recognized tax expense of approximately $5 million associated with the establishment of a valuation allowance against the net deferred tax assets of its Australian subsidiary. The tax effects of differences that give rise to significant portions of the deferred income tax assets and deferred income tax liabilities as of December 31 were as follows: In millions 2021 2020 Deferred Income Tax Assets: Compensation Based Accruals $ 4 $ 4 Net Operating Loss Carryforwards 192 40 Postretirement Benefits 1 1 Tax Credits 31 19 Other 37 9 Valuation Allowance (38) (34) Total Deferred Income Tax Assets $ 227 $ 39 Deferred Income Tax Liabilities: Property, Plant and Equipment (108) (21) Goodwill (3) (3) Other Intangibles (108) (11) Investment in Partnership (564) (531) Net Noncurrent Deferred Income Tax Liabilities $ (783) $ (566) Net Deferred Income Tax Liability $ (556) $ (527) The Company has total deferred income tax assets, excluding valuation allowance, of $265 million and $73 million as of December 31, 2021 and 2020, respectively. The Company has total deferred income tax liabilities of $783 million and $566 million as of December 31, 2021 and 2020, respectively. As a result of International Paper’s final exchange in 2021, the Company currently owns 100% of the outstanding interests in GPIP. GPIP continues to be treated as a partnership for U.S. federal and state income tax purposes despite International Paper’s exit as a minority partner. Accordingly, as a result of the continuation of the partnership, domestic deferred tax assets and liabilities are not tracked based on the inside basis difference of assets and liabilities held within GPIP. Instead, the Company’s outside basis difference in its partnership investment is recorded as a deferred tax liability and disclosed above. The deferred tax liability primarily relates to differences between book and tax basis in property, plant and equipment and intangibles inside the partnership. During 2021 and 2020, IP redeemed or exchanged its entire interest in the partnership. As a result of the redemptions and exchanges, the Company recorded a decrease in its deferred tax liability in 2021 and 2020 of $175 million and $16 million, respectively, which was recorded through additional paid-in capital. According to the Income Taxes topic of the FASB Codification, a valuation allowance is required to be established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The FASB Codification provides important factors in determining whether a deferred tax asset will be realized, including whether there has been sufficient pretax income in recent years and whether sufficient income can reasonably be expected in future years in order to utilize the deferred tax asset. The Company has evaluated the need to maintain a valuation allowance for deferred tax assets based on its assessment of whether it is more likely than not that deferred tax assets will be realized through the generation of future taxable income. Appropriate consideration was given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. The Company reviewed its deferred income tax assets as of December 31, 2021 and 2020, respectively, and determined that it is more likely than not that a portion will not be realized. A valuation allowance of $38 million and $34 million at December 31, 2021 and 2020, respectively, is maintained on the deferred income tax assets for which the Company has determined that realization is not more likely than not. Of the total valuation allowance at December 31, 2021, $30 million relates to net deferred tax assets in certain foreign jurisdictions, $1 million relates to U.S. foreign tax credit carryforwards, $5 million relates to tax credit carryforwards in certain states, and the remaining $2 million relates to net operating losses in certain U.S. states. The need for a valuation allowance is made on a jurisdiction-by-jurisdiction basis. As of December 31, 2021, the Company concluded that due to cumulative pretax losses and the lack of sufficient future taxable income of the appropriate character, realization is less than more likely than not on the net deferred income tax assets related primarily to the Company’s operations in Australia, Brazil, Netherlands, and Norway as well as certain operations in Germany. The following table represents a summary of the valuation allowances against deferred tax assets as of and for the three years ended December 31, 2021, 2020, and 2019, respectively: December 31, In millions 2021 2020 2019 Balance Beginning of Period $ 34 $ 41 $ 36 Adjustments for (Income) and Expenses 1 (7) 5 Additions (Deductions) 3 — — Balance at End of Period $ 38 $ 34 $ 41 The Company utilized its remaining U.S. federal net operating loss carryforwards during 2020. However, as a result of deductions associated with the step up in tax basis of certain assets as a result of International Paper’s exit from the partnership, the Company generated a taxable loss of $574 million during 2021 that can be carried forward for U.S. federal income tax purposes indefinitely. Therefore, based on the net operating loss generated in 2021 as well as future tax benefits associated with planned capital projects and tax credit carryforwards, which are available to offset future U.S. federal income tax, the Company does not expect to be a meaningful U.S. federal cash taxpayer until 2024. The Company's U.S. state net operating loss carryforwards total $587 million and expire in various years through 2041. International net operating loss carryforward amounts total $191 million, of which substantially all have no expiration date. Tax Credit carryforwards total $31 million which expire in various years through 2041. Uncertain Tax Positions A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: In millions 2021 2020 2019 Balance at January 1, $ 20 $ 21 $ 16 Additions for Tax Positions of Current Year 1 1 2 Additions for Tax Positions of Prior Years 3 2 3 Reductions for Tax Positions of Prior Years — (4) — Balance at December 31, $ 24 $ 20 $ 21 At December 31, 2021, $24 million of the total gross unrecognized tax benefits, if recognized, would affect the annual effective income tax rate. As of December 31, 2021, none of the total gross unrecognized tax benefits recorded are related to indefinite lived deferred tax assets and did not have an impact on total tax expense. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within its global operations in Income Tax Expense. The Company had an immaterial accrual for the payment of interest and penalties at December 31, 2021. The Company anticipates that $1 million of the total unrecognized tax benefits at December 31, 2021 could change within the next 12 months. The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions and our income tax filings are regularly examined by federal, state and non-U.S. tax authorities. The Company’s 2018 U.S. federal corporate and partnership income tax filings are currently under examination by the Internal Revenue Service. With few exceptions, the Company is no longer subject to U.S. federal, state and local tax examinations for years before 2017. As of December 31, 2021, the Company has provided for deferred income taxes attributable to future foreign withholding tax expense related to the Company's equity investment in the joint venture, Rengo Riverwood Packaging, Ltd. In addition, Company provides deferred income taxes for future Canadian withholding tax to the extent of excess cash available for distribution after consideration of working capital needs and other debt settlement of its Canadian subsidiary, Graphic Packaging International Canada, ULC. The Company continues to assert that it is permanently reinvested in the cumulative earnings of its Canadian subsidiary in excess of the amount of cash that is on hand and available for distribution after consideration of working capital needs and other debt settlement. Due to the deemed taxation of all post-1986 earnings and profits required by the Act, the Company has determined that no deferred tax liability should be recorded related to the outside basis difference of its Canadian subsidiary of approximately $51 million as of December 31, 2021. The Company has not provided for deferred U.S. income taxes on approximately $33 million of its undistributed earnings in other international subsidiaries because of the Company’s intention to indefinitely reinvest these earnings outside the U.S. The Company’s assertion remains unchanged, despite the deemed taxation of all post-1986 earnings and profits required by the Act. The determination of the amount of the unrecognized deferred U.S. income tax liability (primarily withholding tax in certain jurisdictions and some state tax) on the unremitted earnings or any other associated outside basis difference is not practicable because of the complexities associated with the calculation. The Company has elected to recognize global intangible low-taxed income (“GILTI”) as period cost as incurred, therefore there are no deferred taxes recognized for basis differences that are expected to impact the amount of the GILTI inclusion upon reversal.

Financial Instruments, Derivati

Financial Instruments, Derivatives and Hedging Activities	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments, Derivatives and Hedging Activities	FINANCIAL INSTRUMENTS, DERIVATIVES AND HEDGING ACTIVITIES The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments under the Derivatives and Hedging topic of the FASB Codification and those not designated as hedging instruments under this guidance. The Company uses interest rate swaps, natural gas swap contracts, and forward exchange contracts. These derivative instruments are designated as cash flow hedges and, to the extent they are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings but are included in Accumulated Other Comprehensive Loss. These changes in fair value will subsequently be reclassified to earnings, contemporaneously with and offsetting changes in the related hedged exposure, and presented in the same line of the income statement expected for the hedged item. Interest Rate Risk The Company uses interest rate swaps to manage interest rate risks on future interest payments caused by interest rate changes on its variable rate term loan facility. Changes in fair value will subsequently be reclassified into earnings as a component of Interest Expense, Net as interest is incurred on amounts outstanding under the term loan facility. The following table summarizes the Company's current interest rate swap positions for each period presented as of December 31, 2021: Start End (In Millions) Notional Amount Weighted Average Interest Rate 12/03/2018 01/01/2022 $120 2.92% 12/03/2018 01/04/2022 $80 2.79% These derivative instruments are designated as cash flow hedges and, to the extent they are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings but are included in Accumulated Other Comprehensive Loss. Ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. During 2021 and 2020, there were no amounts of ineffectiveness. During 2021 and 2020, there were no amounts excluded from the measure of effectiveness. Commodity Risk To manage risks associated with future variability in cash flows and price risk attributable to purchases of natural gas, the Company enters into natural gas swap contracts to hedge prices for a designated percentage of its expected natural gas usage. Such contracts are designated as cash flow hedges. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss and resulting gain or loss reclassified into Cost of Sales concurrently with the recognition of the commodity consumed. The Company has hedged approximately 17% of its expected natural gas usage for 2022. During 2021 and 2020, there were no amounts of ineffectiveness related to changes in the fair value of natural gas swap contracts. Additionally, there were no amounts excluded from the measure of effectiveness. Foreign Currency Risk The Company enters into forward exchange contracts to manage risks associated with foreign currency transactions and future variability of cash flows arising from those transactions that may be adversely affected by changes in exchange rates. The contracts are carried at fair value with changes in fair value recognized in Accumulated Other Comprehensive Loss and gains/losses related to these contracts are recognized in Other Expense, Net or Net Sales, when appropriate. At December 31, 2020, multiple forward exchange contracts existed that expired on various dates throughout 2021. Those purchased forward exchange contracts outstanding at December 31, 2020, when aggregated and measured in U.S. dollars at contractual rates at December 31, 2020, had notional amounts totaling $102 million. No amounts were reclassified to earnings during 2021 and 2020 in connection with forecasted transactions that were considered probable of not occurring and there was no amount of ineffectiveness related to changes in the fair value of foreign currency forward contracts. Additionally, there were no amounts excluded from the measure of effectiveness during 2021 and 2020. Derivatives not Designated as Hedges The Company enters into forward exchange contracts to effectively hedge substantially all of its accounts receivables resulting from sales transactions and intercompany loans denominated in foreign currencies in order to manage risks associated with variability in cash flows that may be adversely affected by changes in exchange rates. At December 31, 2021 and 2020, multiple foreign currency forward exchange contracts existed, with maturities ranging up to six months. Those foreign currency contracts outstanding at December 31, 2021 and 2020, when aggregated and measured in U.S. dollars at contractual rates at December 31, 2021 and 2020, respectively, had net notional amounts totaling $103 million and $80 million. Unrealized gains and losses resulting from these contracts are recognized in Other Expense, Net and approximately offset corresponding recognized but unrealized gains and losses on the remeasurement of these accounts receivable. Deal Contingent Hedge On May 14, 2021, in connection with the AR Packaging acquisition, the Company entered into deal contingent foreign exchange forward contracts, with no upfront cash cost, to hedge €700 million of the acquisition price. These forward contracts settled October 29, 2021 concurrently with the acquisition of AR Packaging and are accounted for as derivatives under ASC 815, Derivatives and Hedging. Unrealized losses of $48 million for the year ended December 31, 2021 resulting from these contracts are recognized in Business Combinations, Shutdown and Other Special Charges, and Exit Activities, Net on the Company’s Condensed Consolidated Statements of Operations. For more information, see " Note 11 — Fair Value Measurement ." Foreign Currency Movement Effect For the year ended December 31, 2021, 2020 and 2019 net currency exchange losses(gains) included in determining Income from Operations were $3 million, $3 million, and $(2) million, respectively.

Fair Value Measurement

Fair Value Measurement	12 Months Ended
	Dec. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurement	FAIR VALUE MEASUREMENT The Company follows the fair value guidance integrated into the Fair Value Measurements and Disclosures topic of the FASB Codification in regards to financial and nonfinancial assets and liabilities. Nonfinancial assets and nonfinancial liabilities include those measured at fair value in goodwill impairment testing, asset retirement obligations initially measured at fair value, and those assets and liabilities initially measured at fair value in a business combination. The FASB’s guidance defines fair value, establishes a framework for measuring fair value and expands the fair value disclosure requirements. The accounting guidance applies to accounting pronouncements that require or permit fair value measurements. It indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The guidance defines fair value based upon an exit price model, whereby fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance clarifies that fair value should be based on assumptions that market participants would use, including a consideration of non-performance risk. Valuation Hierarchy The Fair Value Measurements and Disclosures topic establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs — quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs — unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company has determined that its financial assets and financial liabilities include derivative instruments which are carried at fair value and are valued using Level 2 inputs in the fair value hierarchy. The Company uses valuation techniques based on discounted cash flow analyses, which reflects the terms of the derivatives and uses observable market-based inputs, including forward rates and uses market price quotations obtained from third party derivatives brokers, corroborated with information obtained from third party pricing service providers. Fair Value of Financial Instruments As of December 31, 2021 and 2020, there has not been any significant impact to the fair value of the Company's derivative liabilities due to its own credit risk. Similarly, there has not been any significant adverse impact to the Company's derivative assets based on evaluation of the Company's counterparties' credit risks. The following table summarizes the fair value of the Company's derivative instruments: Derivative Assets (a) Derivative Liabilities (b) December 31, December 31, In millions 2021 2020 2021 2020 Derivatives designated as hedging instruments: Interest rate contracts $ — $ — $ — $ 6 Foreign currency contracts — — — 3 Commodity contracts 2 2 — — Total Derivatives $ 2 $ 2 $ — $ 9 (a) Derivative assets of $2 million are included in Other Current Assets as of December 31, 2021 and 2020 (b) Derivative liabilities of $9 million are included in Other Accrued Liabilities as of December 31, 2020 The fair values of the Company’s other financial assets and liabilities at December 31, 2021 and 2020 approximately equal the carrying values reported on the Consolidated Balance Sheets except for Long-Term Debt. The fair value of the Company’s Long-Term Debt (excluding finance leases and deferred financing fees) was $5,715 million and $3,625 million, as compared to the carrying amounts of $5,676 million and $3,524 million as of December 31, 2021 and 2020, respectively. The fair value of the Company's Total Debt, including the Senior Notes, are based on quoted market prices (Level 2 inputs). Level 2 valuation techniques for Long-Term Debt are based on quotations obtained from third party pricing service providers. Effect of Derivative Instruments The pre-tax effect of derivative instruments in cash flow hedging relationships on the Company’s Consolidated Statements of Operations for the year ended December 31, 2021 and 2020 is as follows: Amount of (Gain) Loss Recognized in Accumulated Other Comprehensive Loss Location in Statement of Operations Amount of (Gain) Loss Recognized in Statement of Operations Year Ended December 31, Year Ended December 31, In millions 2021 2020 2019 2021 2020 2019 Commodity Contracts $ (11) $ 1 $ 1 Cost of Sales $ (11) $ 6 $ (2) Foreign Currency Contracts (2) 2 — Other Expense, Net 2 — (1) Interest Rate Swap Agreements — 6 6 Interest Expense, Net 6 7 1 Total $ (13) $ 9 $ 7 $ (3) $ 13 $ (2) At December 31, 2021, the Company expects to reclassify $3 million of pre-tax gain in the next twelve months from Accumulated Other Comprehensive Loss to earnings, contemporaneously with and offsetting changes in the related hedged exposure.

Environmental and Legal Matters	ENVIRONMENTAL AND LEGAL MATTERS Environmental Matters The Company is subject to a broad range of foreign, federal, state and local environmental, health and safety laws and regulations, including those governing discharges to air, soil and water, the management, treatment and disposal of hazardous substances, solid waste and hazardous wastes, the investigation and remediation of contamination resulting from historical site operations and releases of hazardous substances, the recycling of packaging and the health and safety of employees. Compliance initiatives could result in significant costs, which could negatively impact the Company’s consolidated financial position, results of operations or cash flows. Any failure to comply with environmental or health and safety laws and regulations or any permits and authorizations required thereunder could subject the Company to fines, corrective action or other sanctions. Some of the Company’s current and former facilities are the subject of environmental investigations and remediations resulting from historic operations and the release of hazardous substances or other constituents. Some current and former facilities have a history of industrial usage for which investigation and remediation obligations may be imposed in the future or for which indemnification claims may be asserted against the Company. Also, closures or sales of facilities may necessitate investigation and may result in remediation activities at those facilities. The Company has established reserves for those facilities or issues where a liability is probable and the costs are reasonably estimable. The Company believes that the amounts accrued for its loss contingencies, and the reasonably possible loss beyond the amounts accrued, are not material to the Company’s consolidated financial position, results of operations or cash flows. The Company cannot estimate with certainty other future compliance, investigation or remediation costs. Some costs relating to historic usage that the Company considers to be reasonably possible of resulting in liability are not quantifiable at this time. The Company will continue to monitor environmental issues at each of its facilities, as well as regulatory developments, and will revise its accruals, estimates and disclosures relating to past, present and future operations, as additional information is obtained. Legal Matters The Company is a party to a number of lawsuits arising in the ordinary conduct of its business. Although the timing and outcome of these lawsuits cannot be predicted with certainty, the Company does not believe that disposition of these lawsuits will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

Segment Reporting [Abstract]
Business Segment and Geographic Area Information	BUSINESS SEGMENT AND GEOGRAPHIC AREA INFORMATION The Company has three reportable segments as follows: Paperboard Mills includes the eight North American paperboard mills that produce primarily CRB, CUK, and SBS, which is consumed internally to produce paperboard packaging for the Americas and Europe Packaging segments. The remaining paperboard is sold externally to a wide variety of paperboard packaging converters and brokers. The Paperboard Mills segment Net Sales represents the sale of paperboard only to external customers. The effect of intercompany transfers to the paperboard packaging segments has been eliminated from the Paperboard Mills segment to reflect the economics of the integration of these segments. Americas Paperboard Packaging includes paperboard packaging, primarily folding cartons, sold primarily to Consumer Packaged Goods ("CPG") companies, and cups, lids and food containers sold primarily to foodservice companies and Quick-Service Restaurants ("QSR") serving the food, beverage, and consumer product markets in the Americas. Europe Paperboard Packaging includes paperboard packaging, primarily folding cartons, sold primarily to CPG companies serving the food, beverage and consumer product markets including healthcare and beauty primarily in Europe. The Company allocates certain mill and corporate costs to the reportable segments to appropriately represent the economics of these segments. The Corporate and Other caption includes the Pacific Rim and Australia operating segments and unallocated corporate and one-time costs. These segments are evaluated by the chief operating decision maker based primarily on Income from Operations as adjusted for depreciation and amortization. The accounting policies of the reportable segments are the same as those described above in "Note 1 - Nature of Business and Summary of Significant Accounting Policies." The Company did not have any one customer who accounted for 10% or more of the Company's net sales during 2021, 2020 or 2019.

Restructuring and Related Activities [Abstract]
Exit Activities	EXIT ACTIVITIES During 2019, the Company announced its plans to invest in a CRB platform optimization project, which included an investment in a new CRB paper machine in Kalamazoo, Michigan. At the time of the announcement, the Company expected to close two of its smaller CRB mills in 2022 in order to remain capacity neutral. During the third quarter of 2021, the Company decided to continue to operate one of these smaller CRB mills at least through 2022. In March 2020, the Company made the decision to close the White Pigeon, Michigan CRB mill and shut down the PM1 containerboard machine in West Monroe, Louisiana. During the second quarter of 2020, the Company closed the White Pigeon, Michigan CRB mill and shut down the PM1 containerboard machine. In June 2020, the Company made the decision to close certain converting plants that were acquired from Greif. The Burlington, North Carolina converting facility and the Los Angeles, California converting facility were closed during 2020. The Company accounts for the costs associated with these closures in accordance with ASC 360, Impairment or Disposal of Long-Lived Assets ("ASC 360"), ASC 420, Exit or Disposal Costs Obligations ("ASC 420") and ASC 712 Compensation-Nonretirement Post-Employment Benefits ("ASC 712"). The Company recorded $38 million and $51 million of exit costs during 2021 and 2020, respectively. Other costs associated with the start-up of the new CRB paper machine will be recorded in the period in which they are incurred. These costs are included in the Corporate and Other caption in "Note 15 - Business Segment and Geographic Area Information." The following table summarizes the costs incurred during 2021 and 2020 related to these restructurings: Year Ended December 31, In millions Location in Statement of Operations 2021 2020 2019 Severance costs and other (a) Business Combinations, Shutdown and Other Special Charges, and Exit Activities, Net $ 21 $ 11 $ 8 Accelerated depreciation Cost of Sales 17 26 5 Inventory and asset write-offs Business Combinations, Shutdown and Other Special Charges, and Exit Activities, Net — 14 2 Total $ 38 $ 51 $ 15 (a) Costs incurred include activities for post-employment benefits, retention bonuses, incentives and professional services.

In conjunction with the CRB platform optimization project and closure of the smaller CRB Mill, the Company currently expects to incur charges associated with these exit activities for post-employment benefits, retention bonuses and incentives in the range of $15 million to $20 million, for accelerated depreciation and inventory and asset write-offs in the range of $45 million to $50 million and for start-up charges of for the new CRB paper machine of approximately $25 million. Through December 31, 2021, the Company has incurred cumulative exit activity charges for post-employment benefits, retention bonuses and incentives of $15 million, accelerated depreciation of $45 million, and start-up charges for the new CRB paper machine of $21 million. For the closures of the White Pigeon, Michigan CRB mill and the shutdown of the PM1 containerboard machine in West Monroe, Louisiana, the Company has incurred cumulative exit activity charges for post-employment benefits of $2 million and accelerated depreciation and inventory and asset write-offs of $17 million through December 31, 2021. The Company does not expect to incur any additional significant costs charges related to these closures.

Nature of Business and Summar_2

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The Company’s Consolidated Financial Statements include all subsidiaries in which the Company has the ability to exercise direct or indirect control over operating and financial policies. Intercompany transactions and balances are eliminated in consolidation. The Company, through its GPIL subsidiary, is a party to a Japanese joint venture, Rengo Riverwood Packaging, Ltd. in which it holds a 50% ownership interest that is accounted for using the equity method.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Actual results could differ from these estimates, and changes in these estimates are recorded when known. Estimates are used in accounting for, among other things, pension benefits, retained insurable risks, slow-moving and obsolete inventory, allowance for doubtful accounts, useful lives for depreciation and amortization, impairment testing of goodwill and long-lived assets, fair values related to acquisition accounting, fair value of derivative financial instruments, share based compensation, deferred income tax assets and potential income tax assessments, and loss contingencies.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include bank deposits and other marketable securities that are highly liquid with maturities of three months or less.
Accounts Receivable and Allowances	Accounts Receivable and Allowances Accounts receivable are stated at the amount owed by the customer, net of an allowance for estimated uncollectible accounts, returns and allowances, and cash discounts. The allowance for doubtful accounts is estimated based on historical experience, current economic conditions and the creditworthiness of customers. Receivables are charged to the allowance when determined to be no longer collectible. The Company has entered into agreements to sell, on a revolving basis, certain trade accounts receivable to third party financial institutions. Transfers under these agreements meet the requirements to be accounted for as sales in accordance with the Transfers and Servicing
Concentration of Credit Risk	Concentration of Credit Risk The Company’s cash, cash equivalents, and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents are placed with financial institutions that management believes are of high credit quality. Accounts receivable are derived from revenue earned from customers located in the U.S. and internationally and generally do not require collateral. For the years ended December 31, 2021, 2020, and 2019, no customer accounted for more than 10% of net sales.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value with cost determined based on standard (which approximates actual), average or actual cost. Work in progress and finished goods inventories are valued at the cost of raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) as incurred and an applicable portion of manufacturing overhead. Inventories are stated net of an allowance for slow-moving and obsolete inventory.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost. Betterments, renewals and extraordinary repairs that extend the life of the asset are capitalized; other repairs and maintenance charges are expensed as incurred. The Company’s cost and related accumulated depreciation applicable to assets retired or sold are removed from the accounts and the gain or loss on disposition is included in income from operations. Interest is capitalized on assets under construction for one year or longer with an estimated spending of $1 million or more. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life. Capitalized interest was $14 million, $7 million and $3 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company assesses its long-lived assets, including certain identifiable intangibles, for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. To analyze recoverability, the Company projects future cash flows, undiscounted and before interest, over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment would be recognized, resulting in a write-down of assets with a corresponding charge to earnings. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. The Company assesses the appropriateness of the useful life of its long-lived assets periodically.
Intangible Assets	Intangible Assets Intangible assets with a determinable life are amortized on a straight-line or accelerated basis over their useful lives. The amortization expense for each intangible asset is recorded in the Consolidated Statements of Operations according to the nature of that asset.
Goodwill	Goodwill The Company tests goodwill for impairment annually as of October 1, as well as whenever events or changes in circumstances suggest that the estimated fair value of a reporting unit may no longer exceed its carrying amount. The Company tests goodwill for impairment at the reporting unit level, which is an operating segment or a level below an operating segment, which is referred to as a component. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and management regularly reviews the operating results of that component. Two or more components of an operating segment are aggregated and deemed a single reporting unit if the components have similar economic characteristics. Potential goodwill impairment is measured at the reporting unit level by comparing the reporting unit’s carrying amount (including goodwill), to the fair value of the reporting unit. When performing the quantitative analysis, the estimated fair value of each reporting unit is determined by utilizing a discounted cash flow analysis based on the Company’s forecasts, discounted using a weighted average cost of capital and market indicators of terminal year cash flows based upon a multiple of EBITDA. If the carrying amount of a reporting unit exceeds its estimated fair value, goodwill is considered impaired. In determining fair value, management relies on and considers a number of factors, including but not limited to, future operating results, business plans, economic projections of revenues and operating margins, forecasts including future cash flows, and market data and analysis, including market capitalization. The assumptions used are based on what a hypothetical market participant would use in estimating fair value. Fair value determinations are sensitive to changes in the factors described above. There are inherent uncertainties related to these factors and judgments in applying them to the analysis of goodwill impairment. Periodically, the Company may perform a qualitative impairment analysis of goodwill associated with each of its reporting units to determine if it is more likely than not that the carrying value of a reporting unit exceeded its fair value. However, the Company performed a quantitative impairment test as of October 1, 2021, and concluded goodwill was not impaired for any of its reporting units.
Retained Insurable Risks	Retained Insurable Risks It is the Company’s policy to self-insure or fund a portion of certain expected losses related to group health benefits and workers’ compensation claims. Provisions for expected losses are recorded based on the Company’s estimates, on an undiscounted basis, of the aggregate liabilities for known claims and estimated claims incurred but not reported.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations are accounted for in accordance with the provisions of the Asset Retirement and Environmental Obligations
International Currency	International Currency The functional currency of the international subsidiaries is usually the local currency for the country in which the subsidiaries own their primary assets. The translation of the applicable currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. Any related translation adjustments are recorded directly to a separate component of Shareholders’ Equity, unless there is a sale or substantially complete liquidation of the underlying foreign investments. Gains and losses on foreign currency transactions are included in Other Expense, Net for the period in which the exchange rate changes. The Company pursues a currency hedging program which utilizes derivatives to reduce the impact of foreign currency exchange fluctuations on its consolidated financial results. Under this program, the Company has entered into forward exchange contracts in the normal course of business to hedge certain foreign currency denominated transactions. Realized and unrealized gains and losses on these forward contracts are included in the measurement of the basis of the related foreign currency transaction when recorded.
Revenue Recognition	Revenue Recognition The Company has two primary activities, manufacturing and converting paperboard, from which it generates revenue from contracts with customers. Revenue is disaggregated primarily by geography and type of activity as further explained in " Note 15 - Business Segment and Geographic Area Information. " All reportable segments and the Australia and Pacific Rim operating segments recognize revenue under the same method, allocate transaction price using similar methods, and have similar economic factors impacting the uncertainty of revenue and related cash flows.
Shipping and Handling	Shipping and Handling The Company includes shipping and handling costs in Cost of Sales.
Research and Development	Research and DevelopmentResearch and development costs, which relate primarily to the development and design of new packaging machines and products and are recorded as a component of Selling, General and Administrative expenses, are expensed as incurred.
New Accounting Pronouncements	Adoption of New Accounting Standards In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . This amendment modifies ASC 740 to simplify the accounting for income taxes. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this new guidance during the three months ended March 31, 2021. The Company’s adoption did not result in any changes in accounting principle upon transition and the impact to the Company’s overall financial statements is immaterial. Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . This standard provides temporary optional expedients and exceptions for applying GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). The ASU can be adopted after its issuance date through December 31, 2022. The Company is currently evaluating the impact of this new accounting guidance. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities . Under the new guidance, the acquirer should determine what contract assets and/or contract liabilities it would have recorded under ASC 606 as of the acquisition date, as if the acquirer had entered into the original contract at the same date and on the same terms as the acquiree. The recognition and measurement of those contract assets and contract liabilities will likely be comparable to what the acquiree has recorded on its books under ASC 606 as of the acquisition date. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in an interim period, for any period for which financial statements have not yet been issued. However, adoption in an interim period other than the first fiscal quarter requires an entity to apply the new guidance to all prior business combinations that have occurred since the beginning of the annual period in which the new guidance is adopted. The Company is currently evaluating the adoption date of ASU 2021-08 and the impact, if any, adoption will have on its financial position and results of operations.
