Summary Of Business And Significant Accounting Policies (Note)	12 Months Ended

Accounting Policies [Abstract]
Summary Of Business And Significant Accounting Policies	NOTE 1 SUMMARY OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES NATURE OF BUSINESS International Paper (the "Company") is a global producer of renewable fiber-based packaging and pulp products with primary markets and manufacturing operations in North America and Europe and additional markets and manufacturing operations in Latin America, North Africa and Asia. Substantially all of our businesses have experienced, and are likely to continue to experience, cycles relating to available industry capacity and general economic conditions. FINANCIAL STATEMENTS These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States that require the use of management’s estimates. Actual results could differ from management’s estimates. Printing Papers Spinoff On October 1, 2021, the Company completed the previously announced spin-off of its Printing Papers segment along with certain mixed-use coated paperboard and pulp businesses in North America, France and Russia into a standalone, publicly-traded company, Sylvamo Corporation ("Sylvamo"). The transaction was implemented through the distribution of shares of the standalone company to International Paper's shareholders (the "Distribution"). As a result of the Distribution, Sylvamo is an independent public company that trades on the New York Stock Exchange under the symbol "SLVM". In addition to the spin-off of Sylvamo, the Company completed the sale of its Kwidzyn, Poland mill on August 6, 2021. All historical operating results of the Sylvamo businesses and Kwidzyn mill have been presented as Discontinued Operations, net of tax, in the consolidated statement of operations. See Note 8 - Divestitures for further details regarding the Sylvamo spin-off and discontinued operations. Russia-Ukraine Conflict The military conflict between Russia and Ukraine, including ongoing sanctions, actions by the Russian government, and associated domestic and global economic and geopolitical conditions, has adversely affected and may continue to adversely affect our Ilim joint venture and our businesses, financial condition, results of operations and cash flows. We recently announced that we have reached an agreement to sell our equity interest in Ilim and have also received from the same purchaser an indication of interest to purchase our equity investment in Ilim Group, however, we cannot be certain if and when the completion of these sales may occur. Our ability to complete such sales is subject to various risks, including (i) purchasers’ inability to obtain necessary regulatory approvals or to finance the purchase pursuant to the terms of the agreement, (ii) adverse actions by the Russian government, and (iii) new or expanded sanctions imposed by the U.S., the United Kingdom, or the European Union or its member countries. We are unable to predict the full impact that Russia’s ongoing invasion of Ukraine, current or potential future sanctions, ongoing or potential disruptions resulting from the conflict, the changing regulatory environment in Russia, negative macroeconomic conditions arising from such conflict, supply chain disruptions, and geopolitical instability and shifts, may have on us or our ability to complete the sale of our interest in the Ilim joint venture. DISCONTINUED OPERATIONS A discontinued operation may include a component or a group of components of the Company's operations. A disposal of a component or a group of components is reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on the Company's operations and financial results when the following occurs: (1) a component (or group of components) meets the criteria to be classified as held for sale; (2) the component or group of components is disposed of by sale; or (3) the component or group of components is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off). For any component classified as held for sale or disposed of by sale or other than by sale, qualifying for presentation as a discontinued operation, the Company reports the results of operations of the discontinued operations (including any gain or loss recognized on the disposal or loss recognized on classification as held for sale of a discontinued operation), less applicable income taxes (benefit), as a separate component in the consolidated statement of operations for current and all prior periods presented. The Company also reports assets and liabilities associated with discontinued operations as separate line items on the consolidated balance sheet. CONSOLIDATION The consolidated financial statements include the accounts of International Paper and subsidiaries for which we have a controlling financial interest, including variable interest entities for which we are the primary beneficiary. All significant intercompany balances and transactions are eliminated. EQUITY METHOD INVESTMENTS The equity method of accounting is applied for investments when the Company has significant influence over the investee’s operations, or when the investee is structured with separate capital accounts. Our material equity method investments are described in Note 11 . OTHER-THAN-TEMPORARY IMPAIRMENT T he Company evaluates our equity method investments for other-than-temporary impairment (OTTI) when circumstances indicate the investment may be impaired. When a decline in fair value is deemed to be an OTTI, an impairment is recognized to the extent that the fair value is less than the carrying value of the investment. We consider various factors in determining whether a loss in value of an investment is other than temporary including: the length of time and the extent to which the fair value has been below cost, the financial condition of the investee, and our intent and ability to retain the investment for a period of time sufficient to allow for recovery of value. Management makes certain judgments and estimates in its assessment including but not limited to: identifying if circumstances indicate a decline in value is other than temporary, expectations about operations, as well as industry, financial, regulatory and market factors. BUSINESS COMBINATIONS The Company allocates the total consideration of the assets acquired and liabilities assumed based on their estimated fair value as of the business combination date. In developing estimates of fair values for long-lived assets, including identifiable intangible assets, the Company utilizes a variety of inputs including forecasted cash flows, anticipated growth rates, discount rates, estimated replacement costs and depreciation and obsolescence factors. Determining the fair value for specifically identified intangible assets such as customer lists and developed technology involves judgment. We may refine our estimates and make adjustments to the assets acquired and liabilities assumed over a measurement period, not to exceed one year. Upon the conclusion of the measurement period or the final determination of the values of assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are charged to the consolidated statement of operations. Subsequent actual results of the underlying business activity supporting the specifically identified intangible assets could change, requiring us to record impairment charges or adjust their economic lives in future periods. See Note 7 for further details. RESTRUCTURING LIABILITIES AND COSTS For operations to be closed or restructured, a liability and related expense is recorded in the period when operations cease. For termination costs associated with employees covered by a written or substantive plan, a liability is recorded when it is probable that employees will be entitled to benefits and the amount can be reasonably estimated. For termination costs associated with employees not covered by a written and broadly communicated policy covering involuntary termination benefits (severance plan), a liability is recorded for costs to terminate employees (one-time termination benefits) when the termination plan has been approved and committed to by management, the employees to be terminated have been identified, the termination plan benefit terms are communicated, the employees identified in the plan have been notified and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The timing and amount of an accrual is dependent upon the type of benefits granted, the timing of communication and other provisions that may be provided in the benefit plan. The accounting for each termination is evaluated individually. See Note 6 for further details. REVENUE RECOGNITION Generally, the Company recognizes revenue on a point-in-time basis when the customer takes title to the goods and assumes the risks and rewards for the goods. For customized goods where the Company has a legally enforceable right to payment for the goods, the Company recognizes revenue over time, which generally is, as the goods are produced. The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based on the most likely amount method outlined in ASC 606. The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company's portfolio of customers to record reductions in revenue that is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers. The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, recognize the incremental costs of obtaining a contract as expense when incurred if the amortization period of the asset the Company would recognize is one year or less, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 for further details. TEMPORARY INVESTMENTS Temporary investments with an original maturity of three months or less and money market funds with greater than three month maturities but with the right to redeem without notice are treated as cash equivalents and are stated at cost, which approximates market value. See Note 9 for further details. INVENTORIES Inventories are valued at the lower of cost or market value and include all costs directly associated with manufacturing products: materials, labor and manufacturing overhead. In the United States, costs of raw materials and finished pulp and paper products, are generally determined using the last-in, first-out method. Other inventories are valued using the first-in, first-out or average cost methods. See Note 9 for further details. LEASED ASSETS Operating lease right of use (ROU) assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company's leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of the Company's leases, the Company applies a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate, and apply the rate based on the currency of the lease, which is updated on a quarterly basis for measurement of new lease liabilities. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases except for certain gas and chemical agreements. See Note 10 for further details. PLANTS, PROPERTIES AND EQUIPMENT Plants, properties and equipment are stated at cost, less accumulated depreciation. Expenditures for betterments are capitalized, whereas normal repairs and maintenance are expensed as incurred. The units-of-production method of depreciation is used for pulp and paper mills, and the straight-line method is used for other plants and equipment. See Note 9 for further details. GOODWILL Annual evaluation for possible goodwill impairment is performed as of the beginning of the fourth quarter of each year, with additional interim evaluation performed when management believes that it is more likely than not, that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. The Company has the option to evaluate goodwill for impairment by first performing a qualitative assessment of events and circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amounts, then the quantitative goodwill impairment test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if the Company does not elect the option to perform an initial qualitative assessment, the Company is required to perform the quantitative goodwill impairment test. In performing this evaluation, the Company estimates the fair value of its reporting unit using a weighted approach based on discounted future cash flows, market multiples and transaction multiples. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions related to forecasts of future revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant assumptions related to revenue multiples and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples. For reporting units whose carrying amount is in excess of their estimated fair value, the reporting unit will record an impairment charge by the amount that the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. IMPAIRMENT OF LONG-LIVED ASSETS Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that indicate that the carrying value of the assets may not be recoverable. A recoverability test is performed by comparing the undiscounted cash flows to carrying value of the assets. The inputs related to the undiscounted cash flows requires judgments as to whether assets are held and used or held for sale, the weighting of operational alternatives being considered by management and estimates of the amount and timing of expected future cash flows from the use of the long-lived assets generated by their use. If the carrying amount is less than the undiscounted cash flows, the fair value of the assets is compared to the carrying value to determine if they are impaired. We estimate fair value using discounted cash flows and other valuation techniques as needed. Impaired assets are recorded at their estimated fair value. INCOME TAXES International Paper uses the asset and liability method of accounting for income taxes whereby deferred income taxes are recorded for the future tax consequences attributable to differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are remeasured to reflect new tax rates in the periods rate changes are enacted. International Paper records its global tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in its income tax returns. Where treatment of a position is uncertain, liabilities are recorded based upon the Company’s evaluation of the “more likely than not” outcome considering technical merits of the position based on specific tax regulations and facts of each matter. Changes to recorded liabilities are only made when an identifiable event occurs that changes the likely outcome, such as settlement with the relevant tax authority, the expiration of statutes of limitation for the subject tax year, change in tax laws, or recent court cases that are relevant to the matter. Accrued interest related to these uncertain tax positions is recorded in our consolidated statement of operations in Interest expense, net. The judgments and estimates made by the Company are based on management’s evaluation of the technical merits of a matter, assisted as necessary by consultation with outside consultants, historical experience and other assumptions that management believes are appropriate and reasonable under current circumstances. Actual resolution of these matters may differ from recorded estimated amounts, resulting in adjustments that could materially affect future financial statements. See Note 13 for further details. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in assessing the need for and magnitude of appropriate valuation allowances against deferred tax assets. This assessment is completed by tax jurisdiction and relies on both positive and negative evidence available, with significant weight placed on recent financial results. Cumulative reported pre-tax income is considered objectively verifiable positive evidence of our ability to generate positive pre-tax income in the future. In accordance with GAAP, when there is a recent history of pre-tax losses, there is little or no weight placed on forecasts for purposes of assessing the recoverability of our deferred tax assets. When necessary, we use systematic and logical methods to estimate when deferred tax liabilities will reverse and generate taxable income and when deferred tax assets will reverse and generate tax deductions. Assumptions, judgment, and the use of estimates are required when scheduling the reversal of deferred tax assets and liabilities, and the exercise is inherently complex and subjective. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. International Paper uses the flow-through method to account for investment tax credits earned on eligible open-loop biomass facilities and combined heat and power system expenditures. Under this method, the investment tax credits are recognized as a reduction to income tax expense in the year they are earned rather than a reduction in the asset basis. ENVIRONMENTAL REMEDIATION COSTS Costs associated with environmental remediation obligations are accrued when such costs are probable and reasonably estimable. Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are discounted to their present value when the amount and timing of expected cash payments are reliably determinable. See Note 14 for further details. TRANSLATION OF FINANCIAL STATEMENTS Balance sheets of international operations are translated into U.S. dollars at year-end exchange rates, while statements of operations are translated at average rates. Adjustments resulting from financial statement translations are included as cumulative translation adjustments in Accumulated other comprehensive income (loss). FAIR VALUE MEASUREMENTS The guidance for fair value measurements and disclosures sets out a fair value hierarchy that groups fair value measurement inputs into the following three classifications: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability reflecting the reporting entity’s own assumptions or external inputs from inactive markets. Transfers between levels are recognized at the end of the reporting period.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Developments	NOTE 2 RECENT ACCOUNTING DEVELOPMENTS Other than as described below, no new accounting pronouncement issued or effective during the fiscal year has had or is expected to have a material impact on the consolidated financial statements. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Government Assistance In November 2021, the FASB issued ASU 2021-10, "Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance." This guidance requires a business entity to provide certain disclosures around assistance received from governments. This guidance is effective for annual reporting periods beginning after December 15, 2021. The Company adopted the provisions of this guidance in 2022. We analyzed the government assistance received by the Company and determined that the amounts received were not material to the Company's consolidated financial statements and related disclosures. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This guidance provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This guidance is effective upon issuance and generally can be applied through December 31, 2024. The Company will apply the amendments in this update to account for contract modifications due to changes in reference rates once those occur. We do not expect these amendments to have a material impact on our consolidated financial statements and related disclosures. Liabilities - Supplier Finance Programs

REVENUE CONTRACT BALANCES A contract asset is created when the Company recognizes revenue on its customized products prior to having an unconditional right to payment from the customer, which generally does not occur until title and risk of loss passes to the customer. A contract liability is created when customers prepay for goods prior to the Company transferring those goods to the customer. The contract liability is reduced once control of the goods is transferred to the customer. The majority of our customer prepayments are received during the fourth quarter each year for goods that will be transferred to customers over the following twelve months. Current liabilities of $38 million and $27 million are included in Other current liabilities in the accompanying consolidated balance sheet as of December 31, 2022 and 2021, respectively. During the second quarter of 2021, the Company also recorded a contract liability of $115 million related to the April 2021 acquisition disclosed in Note 7 - Acquisitions . The balance of this contract liability was $99 million and $107 million at December 31, 2022 and 2021, respectively, and is recorded in Other current liabilities and Other Liabilities in the accompanying consolidated balance sheet. The difference between the opening and closing balances of the Company's contract assets and contract liabilities primarily results from the difference between the price and quantity at comparable points in time for goods which we have an unconditional right to payment or receive prepayment from the customer, respectively. PERFORMANCE OBLIGATIONS AND SIGNIFICANT JUDGMENTS International Paper's principal business is to manufacture and sell fiber-based packaging and pulp goods. As a general rule, none of our businesses provide equipment installation or other ancillary services outside of producing and shipping packaging and pulp products to customers. The nature of the Company's contracts can vary based on the business, customer type and region; however, in all instances it is International Paper's customary business practice to receive a valid order from the customer, in which each parties' rights and related payment terms are clearly identifiable. Contracts or purchase orders with customers could include a single type of product or it could include multiple types/grades of products. Regardless, the contracted price with the customer is agreed to at the individual product level outlined in the customer contracts or purchase orders. The Company does not bundle prices; however, we do negotiate with customers on pricing and rebates for the same products based on a variety of factors (e.g. level of contractual volume, geographical location, etc.). Management has concluded that the prices negotiated with each individual customer are representative of the stand-alone selling price of the product.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	PRINTING PAPERS SPIN-OFF 2021: On October 1, 2021, the Company completed the previously announced spin-off of its Printing Papers segment along with certain mixed-use coated paperboard and pulp businesses in North America, France and Russia into a standalone, publicly-traded company, Sylvamo Corporation. The transaction was implemented through the distribution of shares of the standalone company to International Paper's shareholders (the "Distribution"). As a result of the Distribution, Sylvamo Corporation is an independent public company that trades on the New York Stock Exchange under the symbol "SLVM". The Distribution was made to the Company's stockholders of record as of the close of business on September 15, 2021 (the "Record Date"), and such stockholders received one share of Sylvamo common stock for every 11 shares of International Paper common stock held as of the close of business on the Record Date. The Company retained 19.9% of the shares of Sylvamo at the time of the separation and this retained investment is discussed further in Note 9 - Supplementary Financial Statement Information . The spin-off was tax-free for the Company and its shareholders for U.S. federal income tax purposes. In connection with the Distribution, on September 29, 2021, the Company and Sylvamo entered into a separation and distribution agreement as well as various other agreements that govern the relationships between the parties following the Distribution, including a transition services agreement, a tax matters agreement and an employee matters agreement. These agreements provided for the allocation between the Company and Sylvamo of assets, liabilities and obligations attributable to periods prior to, at and after the Distribution and govern certain relationships between the Company and Sylvamo after the Distribution. The Company was also party to various ongoing operational agreements with Sylvamo under which it sold fiber, paper and other products. Related party sales under these agreements were $630 million and $185 million for the year ended December 31, 2022 and 2021, respectively. As of the end of the third quarter 2022, the Company no longer had an ownership interest in Sylvamo and as such will no longer be a related party. See Note 9 - Supplementary Financial Statement Information for further discussion. All historical operating results of the Sylvamo businesses, as well as the results of our Kwidzyn, Poland mill that was sold on August 6, 2021, are presented as Discontinued Operations, net of tax, in the consolidated statement of operations. Kwidzyn was previously part of the Printing Papers business prior to its sale in August 2021. See the Kwidzyn Mill section below for further details regarding this sale. The following summarizes the major classes of line items comprising Earnings (Loss) Before Income Taxes and Equity Earnings reconciled to Discontinued Operations, net of tax, related to the Sylvamo Corporation businesses and Kwidzyn for all prior periods presented in the consolidated statement of operations: In millions 2021 2020 Net Sales $ 2,417 $ 3,015 Costs and Expenses Cost of products sold 1,508 2,036 Selling and administrative expenses 224 165 Depreciation, amortization and cost of timber harvested 113 196 Distribution expenses 229 264 Taxes other than payroll and income taxes 24 35 Net (gains) losses on sales of fixed assets (86) — Net (gains) losses on sales and impairments of businesses (351) — Interest expense, net (19) (2) Earnings (Loss) Before Income Taxes and Equity Earnings 775 321 Income tax provision (benefit) 145 69 Discontinued Operations, Net of Taxes $ 630 $ 252 The following summarizes the total cash provided by operations and total cash used for investing activities related to the Sylvamo Corporation businesses and Kwidzyn and included in the consolidated statement of cash flows: In millions 2021 2020 Cash Provided by (Used For) Operating Activities $ 290 $ 463 Cash Provided by (Used For) Investment Activities $ 757 $ (111) In anticipation of the spin-off, Sylvamo incurred $1.5 billion in debt during the third quarter of 2021 with the proceeds used for a distribution to the Company and other expenses associated with the transaction. The Company was an obligor of the debt prior to the spin-off as Sylvamo was a wholly-owned subsidiary. Subsequent to the distribution of the net assets, the Company was no longer an obligor of the Sylvamo debt. The $1.5 billion of borrowings was comprised of $450 million of 7.00% senior unsecured notes due 2029 issued in September 2021. It was also comprised of the senior secured credit facility that Sylvamo entered into in September 2021 which consisted of $450 million of borrowings related to its term loan “B” facility, $520 million of borrowings related to its term loan “F” facility, and the $100 million draw on its revolving credit facility which had a capacity of $450 million. Additionally, at the time of the spin-off in the fourth quarter of 2021, the Company distributed $130 million to Sylvamo. The debt issuance and distribution to Sylvamo Corporation are classified as financing activities in the accompanying consolidated statement of cash flows. KWIDZYN MILL 2021: On August 6, 2021, the Company completed the sale of its Kwidzyn, Poland mill for €669 million (approximately $794 million using the July 31, 2021 exchange rate) in cash. The business included the pulp and paper mill in Kwidzyn and supporting functions. During the third quarter of 2021, the Company recorded a net gain of $360 million ($350 million after taxes) including a gain of $404 million ($394 million after taxes) related to the sale of net assets and a loss of $44 million (before and after taxes) related to the cumulative foreign currency translation loss. During the fourth quarter of 2021, the Company incurred $9 million ($6 million after taxes) of costs related to the sale of Kwidzyn. All historical operating results for Kwidzyn have been presented as Discontinued Operations, net of tax, in the consolidated statement of operations.

During the twelve months ended December 31, 2021, the Company recorded a net gain of $4 million ($2 million after taxes) related to the business working capital adjustment and cumulative foreign currency translation loss. In conjunction with the announced agreement in the fourth quarter of 2020, a determination was made that the current book value of the Olmuksan International Paper disposal group exceeded its estimated fair value of $79 million which was based on the agreed upon transaction price. As a result, a preliminary charge of $123 million (before and after taxes) was recorded during the fourth quarter of 2020. BRAZIL PACKAGING 2020: On October 14, 2020, the Company closed the previously announced sale of its Brazilian Industrial Packaging business for R$330 million ($58.5 million U.S. dollars), with R$280 million ($49.6 million U.S. dollars) paid at closing and R$50 million ($8.9 million U.S. dollars) to be paid one year from closing. This business included three containerboard mills and four box plants and the agreement followed International Paper's previously announced strategic review of the Brazilian Industrial Packaging business.

CURRENT INVESTMENTS As a result of the 2021 spin-off of Sylvamo, the Company retained 19.9% of the shares of Sylvamo with the intent to monetize its investment and provide additional proceeds to the Company. In the second quarter 2022, the Company exchanged 4,132,000 shares of Sylvamo common stock owned by the Company in exchange and as repayment for an approximately $144 million term loan obligation which resulted in the reversal of a $31 million deferred tax liability due to the tax-free exchange of the Sylvamo Corporation common stock. In the third quarter 2022, the Company exchanged the remaining 4,614,358 shares of Sylvamo common stock owned by the Company in exchange for $167 million and as partial repayment of a $210 million term loan obligation. This also resulted in the reversal of a $35 million deferred tax liability due to the tax-free exchange of the Sylvamo Corporation common stock. See Note 1 6 - Debt and Lines of Credit for further discussion. As of the end of the third quarter 2022, the Company no longer had an ownership interest in Sylvamo. The Company's investment in Sylvamo was valued at $245 million at December 31, 2021, and was recorded in Current investments in the accompanying consolidated balance sheet.

In connection with potential future closures or redesigns of certain production facilities, it is possible that the Company may be required to take steps to remove certain materials from these facilities. Applicable regulations and standards provide that the removal of certain materials would only be required if the facility were to be demolished or underwent major renovations. At this time, any such obligations have an indeterminate settlement date, and the Company believes that adequate information does not exist to apply an expected-present-value technique to estimate any such potential obligations. Accordingly, the Company does not record a liability for such remediation until a decision is made that allows reasonable estimation of the timing of such remediation.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments and Joint Ventures Disclosure [Text Block]	NOTE 11 EQUITY METHOD INVESTMENTS The Company accounts for the following investments under the equity method of accounting. ILIM S.A. ("Ilim") The Company holds a 50% equity interest in Ilim, the holding company for its Ilim joint venture (JV), which has subsidiaries, including JSC Ilim Group, whose primary operations are in Russia. The Company recently announced that it had entered into an agreement to sell its interest in Ilim to its JV partners for $484 million. The completion of the sale is subject to various closing conditions, including the receipt of regulatory approvals in Russia. The Company also received an indication of interest from its JV partners to purchase all of the Company’s shares (constituting a 2.39% stake) in JSC Ilim Group for $24 million, on terms and conditions to be agreed. The Company intends to pursue an agreement to sell the JSC Ilim Group shares, and to divest other non-material residual interests associated with Ilim, to its JV partners. In conjunction with the entry into the announced agreement, a determination was made that the book value of the Ilim and JSC Ilim Group investments plus associated cumulative translation losses, exceeded fair value, based upon the agreed upon transaction price for Ilim and the offer price for JSC Ilim Group. As a result, an other than temporary impairment of $533 million was recorded in the fourth quarter of 2022 to write down these investments to fair value. The impairment charge included $375 million of foreign currency cumulative translation adjustment loss. As of December 31, 2022, the $375 million of cumulative translation adjustment loss remained within AOCI with the recognition of this loss recorded as an offset to the investment balance. The Company also evaluated facts and circumstances as of December 31, 2022 and concluded that the held for sale balance sheet classification criteria had been met as of that date and therefore have classified the Ilim investment balance, net of impairment, as Assets held for sale. Additionally, the December 31, 2021 investment balance has been reclassified to Long-Term Assets Held for Sale. All current and historical results of the Ilim investment are presented as Discontinued Operations, net of taxes in the consolidated statement of operations. The Company recorded equity earnings, net of taxes, of $296 million, $311 million, and $48 million in 2022, 2021, and 2020, respectively, for Ilim. Equity earnings includes an after-tax foreign exchange (loss) gain of $(50) million in 2020, primarily on the remeasurement of U.S. dollar-denominated net debt. Foreign exchange gains (losses) included in equity earnings in 2022 and 2021, were not material. JSC Ilim Group had no U.S. dollar-denominated debt outstanding as of December 31, 2022. The Company received cash dividends from the joint venture of $204 million, $154 million and $141 million in 2022, 2021 and 2020, respectively. At December 31, 2022 and 2021, the Company's investment in Ilim, which is recorded in Assets held for sale in the consolidated balance sheet, was $133 million and $557 million, respectively, which was $403 million lower and $121 million higher, respectively, than the Company's proportionate share of the joint venture's underlying net assets. Prior to the spin-off of the Printing Papers segment on October 1, 2021, the Company was party to a joint marketing agreement with JSC Ilim Group, a subsidiary of Ilim, under which the Company purchased, marketed and sold paper produced by JSC Ilim Group. Purchases under this agreement were $125 million and $174 million for the years ended December 31, 2021 and 2020, respectively. The joint marketing agreement was conveyed to Sylvamo as part of the spin-off transaction on October 1, 2021.

(b) Reflects the goodwill for the acquisitions of EMEA Industrial Packaging box plants. (c) Reflects the impairment of the EMEA Industrial Packaging reporting unit. The Company performed its annual testing of its reporting units for possible goodwill impairments by applying the qualitative assessment to its North America Industrial Packaging reporting unit and the quantitative goodwill impairment test to its EMEA Industrial Packaging reporting unit as of October 1, 2022. For the current year evaluation, the Company assessed various assumptions, events and circumstances that would have affected the estimated fair value of the North America Industrial Packaging reporting unit under the qualitative assessment and the results of the qualitative assessments indicated that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. The Company also performed the quantitative goodwill impairment test which included comparing the carrying amount of the EMEA Industrial Packaging reporting unit to its estimated fair value. The estimated fair value of the reporting unit was calculated using a weighted approach based on discounted future cash flows, market multiples and transaction multiples which are classified as Level 2 and Level 3 within the fair value hierarchy. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions related to forecasts of future revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant assumptions related to revenue multiples and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples. The results of our quantitative goodwill impairment test indicated that the carrying amount exceeded the estimated fair value of the EMEA Industrial Packaging reporting unit and it was determined that all of the goodwill in the reporting unit, totaling $76 million, was impaired. The decline in the fair value of EMEA Industrial Packaging and resulting impairment charge was due to the impacts of certain negative macroeconomic conditions, including the impacts from inflation and the geopolitical environment to the reporting unit.

The net change in the current year includes an increase impacting the future utilization of foreign deferred tax assets of $45 million. Deferred income tax assets and liabilities are recorded in the accompanying consolidated balance sheet under the captions Deferred charges and other assets and Deferred income taxes, respectively. The $485 million of deferred tax liabilities for forestlands, related installment sales, and investment in subsidiary is attributable to a 2007 Temple-Inland installment sale of forestlands (see Note 15 ). A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2022, 2021 and 2020 is as follows: In millions 2022 2021 2020 Balance at January 1 $ (166) $ (143) $ (166) (Additions) reductions for tax positions related to current year (7) (13) (10) (Additions) for tax positions related to prior years (10) (23) (10) Reductions for tax positions related to prior years 3 1 30 Settlements 1 10 13 Expiration of statutes of 1 1 1 Currency translation adjustment 1 1 (1) Balance at December 31 $ (177) $ (166) $ (143) If the Company were to prevail on the unrecognized tax benefits recorded, substantially all of the balances at December 31, 2022, 2021 and 2020 would benefit the effective tax rate. The Company accrues interest on unrecognized tax benefits as a component of interest expense. Penalties, if incurred, are recognized as a component of income tax expense. The Company had approximately $29 million and $21 million accrued for the payment of estimated interest and penalties associated with unrecognized tax benefits at December 31, 2022 and 2021, respectively. The Company is currently subject to audits in the United States and other taxing jurisdictions around the world. Generally, tax years 2009 through 2021 remain open and subject to examination by the relevant tax authorities. The Company frequently faces challenges regarding the amount of taxes due. These challenges include positions taken by the Company related to the timing, nature, and amount of deductions and the allocation of income among various tax jurisdictions. Pending audit settlements and the expiration of statute of limitations could reduce the uncertain tax positions by $28 million during the next twelve months. The Company provides for foreign withholding taxes and any applicable U.S. state income taxes on earnings intended to be repatriated from non-U.S. subsidiaries, which we believe will be limited in the future to each year's current earnings. No provision for these taxes on approximately $1.9 billion of undistributed earnings of non-U.S. subsidiaries as of December 31, 2022 has been made, as these earnings are considered indefinitely invested. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted in a taxable manner is not practicable. If management decided to monetize the Company’s foreign investments, we would recognize the tax cost related to the excess of the book value over the tax basis of those investments. This would include foreign withholding taxes and any applicable U.S. Federal and state income taxes. Determination of the tax cost that would be incurred upon monetization of the Company’s foreign investments is not practicable; however, we do not believe it would be material.

Where liabilities for such matters are determined to be probable and reasonably estimable, accrued liabilities are recorded at the time of sale as a cost of the transaction. Brazil Goodwill Tax Matter : The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by Sylvamo do Brasil Ltda. ("Sylvamo Brazil"), a wholly-owned subsidiary of the Company, until the October 1, 2021 spin-off of the Printing Papers business after which it became a subsidiary of Sylvamo. Sylvamo Brazil received assessments for the tax years 2007-2015 totaling approximately $111 million in tax, and $361 million in interest, penalties, and fees as of December 31, 2022 (adjusted for variation in currency exchange rates). After an initial favorable ruling challenging the basis for these assessments, Sylvamo Brazil received subsequent unfavorable decisions from the Brazilian Administrative Council of Tax Appeals. Sylvamo Brazil has appealed these decisions and intends to appeal any future unfavorable administrative judgments to the Brazilian federal courts; however, this tax litigation matter may take many years to resolve. Sylvamo Brazil and International Paper believe the transaction underlying these assessments was appropriately evaluated, and that Sylvamo Brazil's tax position would be sustained, based on Brazilian tax law. This matter pertains to a business that was conveyed to Sylvamo as of October 1, 2021, as part of our spin-off transaction. Pursuant to the terms of the tax matters agreement entered into between the Company and Sylvamo, the Company will pay 60% and Sylvamo will pay 40%, on up to $300 million of any assessment related to this matter, and the Company will pay all amounts of the assessment over $300 million. Under the terms of the agreement, decisions concerning the conduct of the litigation related to this matter, including strategy, settlement, pursuit and abandonment, will be made by the Company. Sylvamo thus has no control over any decision related to this ongoing litigation. The Company intends to vigorously defend this historic tax position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015. The Brazilian government may enact a tax amnesty program that would allow Sylvamo Brazil to resolve this dispute for less than the assessed amount. As of October 1, 2021, in connection with the recording of the distribution of assets and liabilities resulting from the spin-off transaction, the Company established a liability representing the initial fair value of the contingent liability under the tax matters agreement. The contingent liability was determined in accordance with ASC 460 "Guarantees" based on the probability weighting of various possible outcomes. The initial fair value estimate and recorded liability as of December 31, 2021 was $48 million and remains this amount at December 31, 2022. This liability will not be increased in subsequent periods unless facts and circumstances change such that an amount greater than the initial recognized liability becomes probable and estimable. ENVIRONMENTAL AND LEGAL PROCEEDINGS Environmental The Company has been named as a potentially responsible party (PRP) in environmental remediation actions under various federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Many of these proceedings involve the cleanup of hazardous substances at large commercial landfills that received waste from many different sources. While joint and several liability is authorized under CERCLA and equivalent state laws, as a practical matter, liability for CERCLA cleanups is typically allocated among the many PRPs. There are other remediation costs typically associated with the cleanup of hazardous substances at the Company’s current, closed and formerly-owned facilities, and recorded as liabilities in the balance sheet. Remediation costs are recorded in the consolidated financial statements when they become probable and reasonably estimable. International Paper has estimated the probable liability associated with these environmental remediation matters Cass Lake: One of the matters included above arises out of a closed wood-treatment facility located in Cass Lake, Minnesota. In June 2011, the United States Environmental Protection Agency (EPA) selected and published a proposed soil remedy at the site with an estimated cost of $46 million. In April 2020, the EPA issued a final plan concerning clean-up standards at a portion of the site, the estimated cost of which is included within the soil remedy referenced above. Kalamazoo River: The Company is a PRP with respect to the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site in Michigan. The EPA asserts that the site is contaminated by polychlorinated biphenyls (PCBs) primarily as a result of discharges from various paper mills located along the Kalamazoo River, including a paper mill formerly owned by St. Regis Paper Company (St. Regis). The Company is a successor in interest to St. Regis. • Operable Unit 5, Area 1: In March 2016, the Company and other PRPs received a special notice letter from the EPA (i) inviting participation in implementing a remedy for a portion of the site known as Operable Unit 5, Area 1, and (ii) demanding reimbursement of EPA past costs totaling $37 million, including $19 million in past costs previously demanded by the EPA. The Company responded to the special notice letter. In December 2016, the EPA issued a unilateral administrative order to the Company and other PRPs to perform the remedy. The Company responded to the unilateral administrative order, agreeing to comply with the order subject to its sufficient cause defenses. • Operable Unit 1: In October 2016, the Company and another PRP received a special notice letter from the EPA inviting participation in the remedial design (RD) component of the landfill remedy for the Allied Paper Mill, which is also known as Operable Unit 1. The Record of Decision (ROD) establishing the final landfill remedy for the Allied Paper Mill was issued by the EPA in September 2016. The Company responded to the Allied Paper Mill special notice letter in December 2016. In February 2017, the EPA informed the Company that it would make other arrangements for the performance of the RD. In the summer 2021, remedial action (RA) activities were initiated by the EPA. In October 2022, the Company received a unilateral administrative order to perform the RA. As a result, the Company increased its reserve by $27 million in the fourth quarter of 2022. The total reserve for the Kalamazoo River superfund site was $37 million and $13 million as of December 31, 2022 and 2021, respectively. In addition, in December 2019, the United States published notice in the Federal Register of a proposed consent decree with NCR Corporation (one of the parties to the allocation/apportionment litigation described below), the State of Michigan and natural resource trustees under which NCR would make payments of more than $100 million and perform work in Operable Unit 5, Areas 2, 3, and 4 at an estimated cost of $136 million. In December 2020, the Federal District Court approved the proposed consent decree. The Company’s CERCLA liability has not been finally determined with respect to these or any other portions of the site, and except as noted above, the Company has declined to perform any work or reimburse the EPA at this time. As noted below, the Company is involved in allocation/apportionment litigation with regard to the site. Accordingly, it is premature to predict the outcome or estimate our maximum reasonably possible loss or range of loss with respect to this site. We have recorded a liability for future remediation costs at the site that are probable and reasonably estimable, and it remains reasonably possible that additional losses in excess of this recorded liability could be material. The Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC (collectively GP) in a contribution and cost recovery action for alleged pollution at the site. NCR Corporation and Weyerhaeuser Company are also named as defendants in the suit. The suit seeks contribution under CERCLA for costs purportedly expended by plaintiffs ($79 million as of the filing of the complaint) and for future remediation costs. In June 2018, the Court issued its Final Judgment and Order, which fixed the past cost amount at approximately $50 million (plus interest to be determined) and allocated to the Company a 15% share of responsibility for those past costs. The Court did not address responsibility for future costs in its decision. In July 2018, the Company and each of the other parties filed notices appealing the Final Judgment and prior orders incorporated into that Judgment. On April 25, 2022, the appellate court reversed the Judgment of the Court, finding that the suit against the Company was time-barred by the applicable statute of limitations. On May 9, 2022, GP filed a petition for remaining with the Sixth Circuit Court of Appeals. The Sixth Circuit issued an order denying GP's petition on July 14, 2022. On November 14, 2022, GP filed a petition for writ of certiorari with the U.S. Supreme Court. The Company has filed a brief in opposition to this writ. Harris County: International Paper and McGinnis Industrial Maintenance Corporation (MIMC), a subsidiary of Waste Management, Inc. (WMI), are PRPs at the San Jacinto River Waste Pits Superfund Site in Harris County, Texas. The PRPs have been actively participating in the activities at the site and share the costs of these activities. In October 2017, the EPA issued a ROD selecting the final remedy for the site: removal and relocation of the waste material from both the northern and southern impoundments. The EPA did not specify the methods or practices needed to perform this work. The EPA’s selected remedy was accompanied by a cost estimate of approximately $115 million ($105 million for the northern impoundment, and $10 million for the southern impoundment). Subsequent to the issuance of the ROD, there have been numerous meetings between the EPA and the PRPs, and the Company continues to work with the EPA and MIMC/WMI to develop the remedial design. To this end, in April 2018, the PRPs entered into an Administrative Order on Consent (AOC) with the EPA, agreeing to work together to develop the remedial design for the northern impoundment. That remedial design work is ongoing. The AOC does not include any agreement to perform waste removal or other construction activity at the site. Rather, it involves adaptive management techniques and a pre-design investigation, the objectives of which include filling data gaps (including but not limited to post-Hurricane Harvey technical data generated prior to the ROD and not incorporated into the selected remedy), refining areas and volumes of materials to be addressed, determining if an excavation remedy is able to be implemented in a manner protective of human health and the environment, and investigating potential impacts of remediation activities to infrastructure in the vicinity. During the first quarter of 2020, through a series of meetings among the Company, MIMC/WMI, our consultants, the EPA and the Texas Commission on Environmental Quality (TCEQ), progress was made to resolve key technical issues previously preventing the Company from determining the manner in which the selected remedy for the northern impoundment would be feasibly implemented. As a result of these developments the Company reserved the following amounts in relation to remediation at this site: (a) $10 million for the southern impoundment; and (b) $55 million for the northern impoundment, which represents the Company's 50% share of our estimate of the low end of the range of probable remediation costs. We submitted the Final Design Package for the southern impoundment to the EPA, and the EPA approved this plan May 7, 2021. The EPA issued a Unilateral Administrative Order for Remedial Action of the southern impoundment on August 5, 2021. An addendum to the Final 100% Remedial Design (Amended April 2021) was submitted to the EPA for the southern impoundment on June 2, 2022. This addendum incorporated additional data collected to date which indicated that additional waste material removal will be required, lengthening the time to complete the remedial action. The Company's estimated cost for the Southern impoundment remedial action as of December 31, 2022 was $25 million. With respect to the northern impoundment, the respondents submitted the final component of the 90% remedial design to the EPA on November 8, 2022. Upon submittal of the final component, an updated engineering estimate was developed and the Company increased the reserved amount by approximately $21 million, which represents the Company's 50% share of our estimate of the low end of the range of probable remediation costs. While several key technical issues have been resolved, respondents still face significant challenges remediating this area in a cost-efficient manner and without a release to the environment, and therefore our discussions with the EPA on the best approach to remediation will continue. Because of ongoing questions regarding cost effectiveness, timing and gathering other technical data, additional losses in excess of our recorded liability are possible. The total reserve for the southern and northern impoundment was $95 million and $60 million as of December 31, 2022 and 2021, respectively. Asbestos-Related Matters We have been named as a defendant in various asbestos-related personal injury litigation, in both state and federal court, primarily in relation to the prior operations of certain companies previously acquired by the Company. As of December 31, 2022, the Company's total recorded liability with respect to pending and future asbestos-related claims was $105 million, net of estimated insurance recoveries. While it is reasonably possible that the Company may incur losses in excess of its recorded liability with respect to asbestos-related matters, we are unable to estimate any loss or range of loss in excess of such liability, and do not believe additional material losses are probable. Antitrust In March 2017, the Italian Competition Authority (ICA) commenced an investigation into the Italian packaging industry to determine whether producers of corrugated sheets and boxes violated the applicable European competition law. In April 2019, the ICA concluded its investigation and issued initial findings alleging that over 30 producers, including our Italian packaging subsidiary (IP Italy), improperly coordinated the production and sale of corrugated sheets and boxes. On August 6, 2019, the ICA issued its decision and assessed IP Italy a fine of €29 million (approximately $31 million at current exchange rates) which was recorded in the third quarter of 2019. We appealed the ICA decision and our appeal was denied on May 25, 2021. However, we continue to believe we have numerous and strong bases to challenge the ICA decision, and we have further appealed the decision to the Italian Council of State. General The Company is involved in various other inquiries, administrative proceedings and litigation relating to environmental and safety matters, personal injury, product liability, labor and employment, contracts, sales of property, intellectual property, tax, and other matters, some of which allege substantial monetary damages. See Note 13 for details regarding a tax matter. Assessments of lawsuits and claims can involve a series of complex judgments about future events, can rely heavily on estimates and assumptions, and are otherwise subject to significant uncertainties. As a result, there can be no certainty that the Company will not ultimately incur charges in excess of presently recorded liabilities. The Company believes that loss contingencies arising from pending matters including the matters described herein, will not have a material effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in pending or threatened legal matters, some of which are beyond the Company's control, and the large or indeterminate damages sought in some of these matters, a future adverse ruling, settlement, unfavorable development, or increase in accruals with respect to these matters could result in future charges that could be material to the Company's results of operations or cash flows in any particular reporting period. Taxes Other Than Payroll and Income Taxes In 2017, the Brazilian Federal Supreme Court decided that the state value-added tax (VAT) should not be included in the basis of federal VAT calculations. In 2018 and 2019, the Brazilian tax authorities published both an internal consultation and a normative ruling with a narrow interpretation of the effects of the case. Based upon the best information available to us at that time, we determined an estimated refund was probable of being realized. As of March 31, 2021, we had recognized a receivable of $11 million based upon the authority's narrow interpretation. On May 13, 2021, the Brazilian Federal Supreme Court ruled again on the case. This ruling provides a much broader definition of the state VAT, which increased the exclusion amount from the Federal VAT calculations. Therefore, we recognized an additional receivable of $70 million during the three months ended June 30, 2021, which brought the total receivable to $81 million as of June 30, 2021. The $70 million of income recognized during the second quarter of 2021 included income of $42 million and income of $28 million of net interest expense and is recorded in Discontinued Operations, net of taxes, in the accompanying consolidated statement of operations. A portion of this receivable has been consumed by offsetting various taxes payable leaving a remaining receivable of $48 million. This remaining receivable was conveyed to Sylvamo Corporation on of October 1, 2021, as part of our spin-off transaction.

Variable Interest Entities [Abstract]
Variable Interest Entities And Preferred Securities Of Subsidiaries	NOTE 15 VARIABLE INTEREST ENTITIES In connection with the acquisition of Temple-Inland in February 2012, two special purpose entities became wholly-owned subsidiaries of International Paper. The use of the two wholly-owned special purpose entities discussed below preserved the tax deferral that resulted from the 2007 Temple-Inland timberlands sales. As of December 31, 2022, this deferred tax liability was $485 million, which will be settled with the maturity of the notes in 2027. In October 2007, Temple-Inland sold 1.55 million acres of timberland for $2.4 billion. The total consideration consisted almost entirely of notes due in 2027 issued by the buyer of the timberland, which Temple-Inland contributed to two wholly-owned, bankruptcy-remote special purpose entities. The notes are shown in Long-term financial assets of variable interest entities in the accompanying consolidated balance sheet and are supported by $2.4 billion of irrevocable letters of credit issued by three banks, which are required to maintain minimum credit ratings on their long-term debt. In December 2007, Temple-Inland's two wholly-owned special purpose entities borrowed $2.1 billion which is shown in Long-term nonrecourse financial liabilities of variable interest entities. The loans are repayable in 2027 and are secured by the $2.4 billion of notes and the irrevocable letters of credit securing the notes, and are nonrecourse to us. The loan agreements provide that if a credit rating of any of the banks issuing the letters of credit is downgraded below the specified threshold, the letters of credit issued by that bank must be replaced within 30 days with letters of credit from another qualifying financial institution. As of both December 31, 2022 and 2021, the fair value of the notes receivable was $2.3 billion. As of both December 31, 2022 and 2021, the fair value of this debt was $2.1 billion. The notes receivable and debt are classified as Level 2 within the fair value hierarchy, which is further defined in Note 17 . Activity between the Company and the 2007 financing entities was as follows: In millions 2022 2021 2020 Revenue (a) $ 65 $ 24 $ 41 Expense (b) 58 24 43 Cash receipts (c) 28 5 29 Cash payments (d) 40 16 40 (a) The revenue is included in Interest expense, net, in the accompanying consolidated statement of operations and includes approximately $19 million for the years ended December 31, 2022, 2021 and 2020, respectively, of accretion income for the amortization of the purchase accounting adjustment on the Financial assets of variable interest entities. (b) The expense is included in Interest expense, net, in the accompanying consolidated statement of operations and includes approximately $7 million for the years ended December 31, 2022, 2021 and 2020 respectively, of accretion expense for the amortization of the purchase accounting adjustment on the Long-term nonrecourse financial liabilities of variable interest entities. (c) The cash receipts are interest received on the Financial assets of special purpose entities. (d) The cash payments are interest paid on Nonrecourse financial liabilities of special purpose entities. In connection with the 2006 sale of approximately 5.6 million acres of forestlands, International Paper received installment notes (the "Timber Notes") totaling approximately $4.8 billion. The Timber Notes were used as collateral for borrowings from third party lenders, which effectively monetized the Timber Notes through the creation of newly formed special purposes entities (the "Entities"). The monetization structure preserved the tax deferral that resulted from the 2006 forestlands sales. During 2015, International Paper initiated a series of actions in order to extend the 2006 monetization structure and maintain the long-term nature of the deferred tax liability. The Entities, with assets and liabilities primarily consisting of the Timber Notes and third-party bank loans (the "Extension Loans"), were restructured which resulted in the formation of wholly-owned, bankruptcy-remote special purpose entities (the "2015 Financing Entities"). In August 2021, the Timber Notes of $4.8 billion and the Extension Loans of $4.2 billion related to the 2015 Financing Entities both matured. We settled the Extension Loans at their maturity with the proceeds from the Timber Notes. This resulted in cash proceeds of approximately $630 million representing our equity in the variable interest entities. Maturity of the installment notes and termination of the monetization structure also resulted in a $72 million tax liability that was paid in the fourth quarter of 2021. On September 2, 2022, the Company and the Internal Revenue Service agreed to settle the previously disclosed timber monetization restructuring tax matter. Under this agreement, the Company will fully resolve the matter and pay $252 million in U.S. federal income taxes. As a result, interest will also be charged upon closing of the audit. The amount of interest expense recognized through December 31, 2022 is $58 million. As of December 31, 2022, $89 million in U.S. federal income taxes and $28 million in interest expense have been paid as a result of the settlement agreement. The remaining $163 million U.S. federal income tax liability and $30 million accrued interest liability are recorded as current liabilities in the balance sheet. As part of the settlement with the Internal Revenue Service, the $72 million tax payment discussed in the preceding paragraph was applied to the 2022 U.S. federal estimated tax payments. The reversal of the Company’s remaining deferred tax liability associated with the 2015 Financing Entities of $604 million was recognized as a one-time tax benefit in the third quarter of 2022. Activity between the Company and the 2015 Financing Entities for the years ended December 31, 2021 and 2020 was as follows: In millions 2021 2020 Revenue (a) $ 61 $ 95 Expense (a) 34 122 Cash receipts (b) 95 95 Cash payments (c) 38 157 (a) The revenue and expense are included in Interest expense, net in the accompanying consolidated statement of operations. (b) The cash receipts are interest received on the Financial assets of variable interest entities. (c) The cash payments represent interest paid on Current nonrecourse financial liabilities of variable interest entities.

Debt And Lines Of Credit [Note Text Block]	NOTE 16 DEBT AND LINES OF CREDIT Amounts related to early debt extinguishment during the years ended December 31, 2022, 2021 and 2020 were as follows: In millions 2022 2021 2020 Early debt reductions (a) $ 503 $ 2,472 $ 1,640 Pre-tax early debt extinguishment costs (b) 93 461 196 (a) Reductions related to notes with interest rates ranging from 3.00% to 8.70% with original maturities from 2021 to 2048 for the years ended December 31, 2022, 2021 and 2020. (b) Amounts are included in Restructuring and other charges in the accompanying consolidated statements of operations. The Company's early debt reductions in 2022 included a debt tender of $498 million with interest rates ranging from 6.40% to 8.70% and maturity dates ranging from 2023 to 2039. In addition, in 2022, the Company had $5 million in open market repurchases related to debt with interest rates ranging from 4.35% to 4.40% and maturity dates ranging from 2047 to 2048. In addition to the early debt reductions, the Company had debt reductions of $514 million in 2022 related primarily to capital leases, debt maturities, and international debt. During the second quarter of 2022, the Company borrowed approximately $144 million under a term loan credit agreement with a third party lender. Subsequently, the Company exchanged 4,132,000 shares of Sylvamo common stock owned by the Company in exchange and as repayment of the approximately $144 million term loan obligation. During the third quarter of 2022, the Company borrowed approximately $210 million under a term loan credit agreement with a third party lender. Subsequently, the Company repaid $167 million of the term loan with an exchange of 4,614,358 shares of Sylvamo common stock owned by the Company. The remainder of the term loan was repaid with cash. During the first quarter of 2022, the Company issued approximately $88 million of debt with an interest rate of 2.65% and a maturity date of 2027. The proceeds from this issuance were used to repay approximately $88 million of outstanding debt that matured on April 1, 2022. During the third quarter of 2022, the Company issued approximately $50 million of debt with a variable rate of interest and a maturity date of 2027. During the fourth quarter of 2022, the Company issued $110 million of debt with a variable rate of interest and a maturity date of 2027. In January 2023, the Company entered into a variable term loan agreement providing for a $600 million term loan which was fully drawn on the date of such loan agreement and matures in 2028. The $600 million debt was issued following the repayment of $410 million of commercial paper earlier in 2023 and will be used to repay debt maturing later in 2023 and general corporate purposes. The Company had debt issuances in 2021 of $1.5 billion related primarily to Sylvamo debt issuances as discussed further in Note 8 - Divestitures . The borrowing capacity of the Company's commercial paper program is $1.0 billion supported by its $1.5 billion credit agreement. In June 2021, the Company extended the maturity date of the $1.5 billion credit facility from December 2022 to June 2026. Under the terms of this program, individual maturities on borrowings may vary, but not exceed one year from the date of issue. Interest bearing notes may be issued either as fixed or floating rate notes. The Company had $410 million borrowings outstanding as of December 31, 2022 and no borrowings outstanding as of December 31, 2021 under this program. The liquidity facilities also previously included up to $550 million of uncommitted financings based on eligible receivables balances under a receivables securitization program that had an expiration date in April 2022. The receivables securitization program was renewed on April 27, 2022 with up to $500 million of uncommitted financings based on eligible receivables balances with the expiration date in April 2024. As of December 31, 2022 and December 31, 2021, the Company had no borrowings outstanding under the program.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives And Hedging Activities [Note Text Block]	NOTE 17 DERIVATIVES AND HEDGING ACTIVITIES International Paper periodically uses derivatives and other financial instruments to hedge exposures to interest rate, commodity and currency risks. International Paper does not hold or issue financial instruments for trading purposes. For hedges that meet the hedge accounting criteria at inception, International Paper formally designates and documents the instrument as a fair value hedge, a cash flow hedge or a net investment hedge of a specific underlying exposure. INTEREST RATE RISK MANAGEMENT Our policy is to manage interest cost using a mixture of fixed-rate and variable-rate debt. To manage this risk in a cost-efficient manner, we enter into interest rate swaps whereby we agree to exchange with the counterparty, at specified intervals, the difference between fixed and variable interest amounts calculated by reference to a notional amount. Interest rate swaps that meet specific accounting criteria are accounted for as fair value or cash flow hedges. For fair value hedges, the changes in the fair value of both the hedging instruments and the underlying debt obligations are immediately recognized in interest expense. For cash flow hedges, the effective portion of the changes in the fair value of the hedging instrument is reported in AOCI and reclassified into interest expense over the life of the underlying debt. The ineffective portion for both cash flow and fair value hedges, which is not material for any year presented, is immediately recognized in earnings. FOREIGN CURRENCY RISK MANAGEMENT We manufacture and sell our products and finance operations in a number of countries throughout the world and, as a result, are exposed to movements in foreign currency exchange rates. The purpose of our foreign currency hedging program is to manage the volatility associated with the changes in exchange rates. To manage this exchange rate risk, we have historically utilized a combination of forward contracts, options and currency swaps. Contracts that qualify are designated as cash flow hedges of certain forecasted transactions denominated in foreign currencies or net investment hedges of foreign denominated subsidiaries. For cash flow hedges, the effective portion of the changes in fair value of these instruments is reported in AOCI and reclassified into earnings in the same financial statement line item and in the same period or periods during which the related hedged transactions affect earnings. The ineffective portion, which is not material for any year presented, is immediately recognized in earnings. For net investment hedges, all changes in the fair value of these instruments are recorded in AOCI, offsetting the currency translation adjustment of the related investment that is also recorded in AOCI. The change in value of certain non-qualifying instruments used to manage foreign exchange exposure of intercompany financing transactions and certain balance sheet items subject to revaluation is immediately recognized in earnings, substantially offsetting the foreign currency mark-to-market impact of the related exposure. COMMODITY RISK MANAGEMENT Certain raw materials used in our production processes are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. To manage the volatility in earnings due to price fluctuations, we may utilize swap contracts or forward purchase contracts. Derivative instruments are reported in the consolidated balance sheets at their fair values, unless the derivative instruments qualify for the normal purchase normal sale ("NPNS") exception under GAAP and such exception has been elected. If the NPNS exception is elected, the fair values of such contracts are not recognized on the balance sheet. Contracts that qualify are designated as cash flow hedges of forecasted commodity purchases. The effective portion of the changes in fair value for these instruments is reported in AOCI and reclassified into earnings in the same financial statement line item and in the same period or periods during which the hedged transactions affect earnings. The ineffective and non-qualifying portions, which are not material for any year presented, are immediately recognized in earnings. The change in the fair value of certain non- qualifying instruments used to reduce commodity price volatility is immediately recognized in earnings. The notional amounts of qualifying and non-qualifying instruments used in hedging transactions were as follows: In millions December 31, 2022 December 31, 2021 Derivatives Not Designated as Hedging Instruments: Electricity contract (MWh) 0.2 0.5 The following table shows gains or losses recognized in AOCI, net of tax, related to derivative instruments: Gain (Loss) In millions 2022 2021 2020 Derivatives in Cash Flow Hedging Relationships: Foreign exchange contracts $ — $ 3 $ (34) Derivatives in Net Investment Hedging Relationships: Foreign exchange contracts — 18 — Interest rate contracts — — 25 Total $ — $ 18 $ 25 During the next 12 months, none of the December 31, 2022 AOCI balance, after tax, is expected to be reclassified to earnings. The amounts of gains and losses recognized in the consolidated statement of operations on qualifying and non-qualifying financial instruments used in hedging transactions were as follows: Gain (Loss) Location of Gain In millions 2022 2021 2020 Derivatives in Cash Flow Hedging Relationships: Foreign exchange contracts $ — $ 10 $ (25) Cost of products sold and Discontinued operations, net of taxes Interest rate contracts (2) (1) (1) Interest expense, net Total $ (2) $ 9 $ (26) Gain (Loss) Location of Gain (Loss) In millions 2022 2021 2020 Derivatives in Fair Value Hedging Relationships: Interest rate contracts $ — $ — $ 38 Interest expense, net Debt — — (38) Interest expense, net Total $ — $ — $ — Derivatives in Net Investment Hedging Relationships: Foreign exchange contracts $ — $ — $ 2 Net (gains) losses on sales and impairments of businesses Total $ — $ — $ 2 Derivatives Not Designated as Hedging Instruments: Electricity Contracts $ 26 $ 15 $ (2) Cost of products sold Foreign exchange contracts — (2) — Cost of products sold Total $ 26 $ 13 $ (2) Fair Value Measurements International Paper’s financial assets and liabilities that are recorded at fair value consist of derivative contracts, including interest rate swaps, foreign currency forward contracts, options and other financial instruments that are used to hedge exposures to interest rate, commodity and currency risks. For these financial instruments, fair value is determined at each balance sheet date using an income approach. All of International Paper’s derivative fair value measurements use Level 2 inputs. Below is a description of the valuation calculation and the inputs used for each class of contract: Interest Rate Contracts Interest rate contracts are valued using swap curves obtained from an independent market data provider. The market value of each contract is the sum of the fair value of all future interest payments between the contract counterparties, discounted to present value. The fair value of the future interest payments is determined by comparing the contract rate to the derived forward interest rate and present valued using the appropriate derived interest rate curve. Foreign Exchange Contracts Foreign currency forward and option contracts are valued using standard valuation models. Significant inputs used in these standard valuation models are foreign currency forward and interest rate curves and a volatility measurement. The fair value of each contract is present valued using the applicable interest rate. All significant inputs are readily available in public markets, or can be derived from observable market transactions. Electricity Contract The Company is party to an electricity contract used to manage market fluctuations in energy pricing. The Company's electricity contract is valued using the Mid-C index forward curve obtained from the Intercontinental Exchange. The market value of the contract is the sum of the fair value of all future purchase payments between the contract counterparties, discounted to present value. The fair value of the future purchase payments is determined by comparing the contract price to the forward price and present valued using International Paper's cost of capital. Since the volume and level of activity of the markets that each of the above contracts are traded in has been normal, the fair value calculations have not been adjusted for inactive markets or disorderly transactions. The following table provides a summary of the impact of our derivative instruments in the consolidated balance sheet: Fair Value Measurements Level 2 – Significant Other Observable Inputs Assets In millions December 31, 2022 December 31, 2021 Derivatives not designated as hedging instruments Electricity contract $ 20 (a) $ 10 (b) (a) Includes $20 million recorded in Other current assets in the accompanying consolidated balance sheet. (b) Included $6 million recorded in Other current assets and $4 million in Deferred charges and other assets recorded in the accompanying consolidated balance sheet. The above contracts are subject to enforceable master netting arrangements that provide rights of offset with each counterparty when amounts are payable on the same date in the same currency or in the case of certain specified defaults. Management has made an accounting policy election to not offset the fair value of recognized derivative assets and derivative liabilities in the consolidated balance sheet. The amounts owed to the counterparties and owed to the Company are considered immaterial with respect to each counterparty and in the aggregate with all counterparties. Credit-Risk-Related Contingent Features International Paper evaluates credit risk by monitoring its exposure with each counterparty to ensure that exposure stays within acceptable policy limits. Credit risk is also mitigated by contractual provisions with the majority of our banks. Certain of the contracts include a credit support annex that requires the posting of collateral by the counterparty or International Paper based on each party’s rating and level of exposure. Based on the Company’s current credit rating, the collateral threshold is generally $15 million. If the lower of the Company’s credit rating by Moody’s or S&P were to drop below investment grade, the Company would be required to post collateral for all of its derivatives in a net liability position, although no derivatives would terminate. There were no derivative instruments containing credit-risk-related contingent

Retirement Benefits [Abstract]
Retirement Plans	International Paper sponsors and maintains the Retirement Plan of International Paper Company (the "Pension Plan"), a tax-qualified defined benefit pension plan that provides retirement benefits to certain employees. The Pension Plan provides defined pension benefits based on years of credited service and either final average earnings (salaried employees and hourly employees receiving salaried benefits), hourly job rates or specified benefit rates (hourly and union employees). The Company also has two unfunded nonqualified defined benefit pension plans: a Pension Restoration Plan that provides retirement benefits based on eligible compensation in excess of limits set by the Internal Revenue Service, and a supplemental retirement plan for senior managers ("SERP"), which is an alternative retirement plan for salaried employees who are senior vice presidents and above or who are designated by the chief executive officer as participants. These nonqualified plans are only funded to the extent of benefits paid, which totaled $29 million, $21 million and $31 million in 2022, 2021 and 2020, respectively, and which are expected to be $22 million in 2023. Effective January 1, 2019, the Company froze participation, including credited service and compensation, for salaried employees under the Pension Plan, the Pension Restoration Plan and the SERP plan. This change does not affect benefits accrued through December 31, 2018. For service after December 31, 2018, employees affected by the freeze receive a company contribution to their individual Retirement Savings Account as described later in this Note 19 . Many non-U.S. employees are covered by various retirement benefit arrangements, some of which are considered to be defined benefit pension plans for accounting purposes. In advance of the spin-off of the Printing Papers segment into a standalone, publicly-traded company, Sylvamo, a legally separate Sylvamo Pension Plan was established to transfer both pension liabilities and qualified pension assets for the approximately 900 active pension participants who transitioned to Sylvamo. Effective September 1, 2021, the Retirement Plan of International Paper (“IP Pension Plan”) and the Sylvamo Pension Plan were legally separated and remeasured as of that date. The remeasurement resulted in a net asset balance of $520 million for the IP Pension Plan, which has been classified as part of the Pension Assets balance on the Consolidated Balance Sheet. Based on the September 1, 2021 remeasurement, the IP Pension Plan completed the transfer of approximately $287 million in projected benefit obligation and approximately $255 million in pension assets, net of post-spin true-up adjustments, to the Sylvamo Pension Plan. OBLIGATIONS AND FUNDED STATUS The following table shows the changes in the benefit obligation and plan assets for 2022 and 2021 and the plans’ funded status. 2022 2021 In millions U.S. Non- U.S. Non- Change in projected benefit obligation: Benefit obligation, January 1 $ 11,833 $ 65 $ 13,020 $ 264 Service cost 85 3 100 5 Interest cost 338 2 333 4 Actuarial loss (gain) (2,863) (11) (760) (11) Divestitures — — (287) (187) Plan amendments 16 — — — Benefits paid (593) (2) (573) (5) Effect of foreign currency exchange rate movements — (3) — (5) Benefit obligation, December 31 $ 8,816 $ 54 $ 11,833 $ 65 Change in plan assets: Fair value of plan assets, January 1 $ 12,075 $ 19 $ 12,018 $ 190 Actual return on plan assets (2,666) — 864 4 Company contributions 29 2 21 6 Benefits paid (593) (2) (573) (5) Divestiture — — (255) (175) Effect of foreign currency exchange rate movements — (1) — (1) Fair value of plan assets, December 31 $ 8,845 $ 18 $ 12,075 $ 19 Funded status, December 31 $ 29 $ (36) $ 242 $ (46) Amounts recognized in the consolidated balance sheet: Overfunded pension plan assets $ 297 $ — $ 595 $ — Underfunded pension benefit obligation - current (22) (2) (21) (1) Underfunded pension benefit obligation - non-current (246) (34) (332) (45) $ 29 $ (36) $ 242 $ (46) Amounts recognized in accumulated other comprehensive income (loss) under ASC 715 (pre-tax): Prior service cost (credit) $ 89 $ — $ 95 $ — Net actuarial loss (gain) 1,563 (7) 1,199 4 $ 1,652 $ (7) $ 1,294 $ 4 The non-current asset for the qualified plan is included in the accompanying consolidated balance sheet under Overfunded Pension Plan Assets. The non-current portion of the liability is included with the pension liability under Underfunded Pension Benefit Obligation. The largest contributor to the actuarial gain affecting the benefit obligation was the increase in the discount rate from 2.90% at December 31, 2021 to 5.40% at December 31, 2022. The components of the $357 million and $(12) million related to U.S. plans and non-U.S. plans, respectively, in the amounts recognized in OCI during 2022 consisted of: In millions U.S. Non- Current year actuarial (gain) loss $ 451 $ (10) Amortization of actuarial loss (87) (1) Current year prior service cost 16 — Amortization of prior service cost (23) — Effect of foreign currency exchange rate movements — (1) $ 357 $ (12) The portion of the change in the funded status that was recognized in net periodic benefit cost and OCI for the U.S. plans was $474 million, $(1.0) billion and $(500) million in 2022, 2021 and 2020, respectively. The portion of the change in funded status for the non-U.S. plans was $(6) million, $(73) million, and $13 million in 2022, 2021 and 2020, respectively. The accumulated benefit obligation at December 31, 2022 and 2021 was $8.8 billion and $11.8 billion, respectively, for our U.S. defined benefit plans and $46 million and $56 million, respectively, at December 31, 2022 and 2021 for our non-U.S. defined benefit plans. The following table summarizes information for pension plans with an accumulated benefit obligation in excess of plan assets at December 31, 2022 and 2021: 2022 2021 In millions U.S. Non-U.S. U.S. Non-U.S. Projected benefit obligation $ 268 $ 54 $ 353 $ 65 Accumulated benefit obligation 268 45 353 56 Fair value of plan assets — 18 — 19 ASC 715, “Compensation – Retirement Benefits” provides for delayed recognition of actuarial gains and losses, including amounts arising from changes in the estimated projected plan benefit obligation due to changes in the assumed discount rate, differences between the actual and expected return on plan assets and other assumption changes. These net gains and losses are recognized prospectively over a period that approximates the average remaining service period of active employees expected to receive benefits under the plans to the extent that they are not offset by gains in subsequent years. NET PERIODIC PENSION EXPENSE Service cost is the actuarial present value of benefits attributed by the plans’ benefit formula to services rendered by employees during the year. Interest cost represents the increase in the projected benefit obligation, which is a discounted amount, due to the passage of time. The expected return on plan assets reflects the computed amount of current-year earnings from the investment of plan assets using an estimated long-term rate of return. Net periodic pension expense for qualified and nonqualified U.S. and non-U.S. defined benefit plans comprised the following: 2022 2021 2020 In millions U.S. Non- U.S. Non- U.S. Non- Service cost $ 85 $ 3 $ 100 $ 5 $ 85 $ 5 Interest cost 338 2 333 4 393 6 Expected return on plan assets (649) (1) (705) (7) (668) (8) Actuarial loss (gain) 87 1 138 2 202 2 Amortization of prior service cost 23 — 22 — 20 — Curtailment loss (gain) — — — — — (1) Settlement loss — — — — — 1 Net periodic pension (income) expense $ (116) $ 5 $ (112) $ 4 $ 32 $ 5 The components of net periodic pension expense other than the Service cost component are included in Non-operating pension (income) expense in the Consolidated Statement of Operations with the exception of $(3) million related to Sylvamo participants in 2021 recorded in Discontinued Operations. The decrease in 2022 pension expense primarily reflects lower asset returns, higher interest cost due to a higher discount rate and lower actuarial loss due to a longer amortization period and lower service cost. ASSUMPTIONS International Paper evaluates its actuarial assumptions annually as of December 31 (the measurement date) and considers changes in these long-term factors based upon market conditions and the requirements for employers’ accounting for pensions. These assumptions are used to calculate benefit obligations as of December 31 of the current year and pension expense to be recorded in the following year (i.e., the discount rate used to determine the benefit obligation as of December 31, 2022 is also the discount rate used to determine net pension expense for the 2023 year). Major actuarial assumptions used in determining the benefit obligations and net periodic pension cost for our defined benefit plans are presented in the following table: 2022 2021 2020 U.S. Non- U.S. Non- U.S. Non- Actuarial assumptions used to determine benefit obligations as of December 31: Discount rate 5.40 % 5.31 % 2.90 % 2.59 % 2.60 % 2.32 % Rate of compensation increase 3.00 % 3.36 % 3.00 % 2.92 % 2.25 % 3.66 % Actuarial assumptions used to determine net periodic pension cost for years ended December 31: Discount rate (a) 2.90 % 2.59 % 2.67 % 2.32 % 3.40 % 2.70 % Expected long-term rate of return on plan assets (a) 6.00 % 3.66 % 6.40 % 4.99 % 7.00 % 4.92 % Rate of compensation increase 3.00 % 2.92 % 2.25 % 3.66 % 2.25 % 3.62 % (a) Represents the weighted average rate for the U.S. qualified plans in 2021 due to the spin-off remeasurement.. The expected long-term rate of return on plan assets is based on projected rates of return for current asset classes in the plan’s investment portfolio. Projected rates of return are developed through an asset/liability study in which projected returns for each of the plan’s asset classes are determined after analyzing historical experience and future expectations of returns and volatility of the various asset classes. Based on the target asset allocation for each asset class, the overall expected rate of return for the portfolio is developed considering the effects of active portfolio management and expenses paid from plan assets. The discount rate assumption was determined from a universe of high quality corporate bonds. A settlement portfolio is selected and matched to the present value of the plan’s projected benefit payments. To calculate pension expense for 2023, the Company will use an expected long-term rate of return on plan assets of 6.50% for the Retirement Plan of International Paper, a discount rate of 5.40% and an assumed rate of compensation increase of 3.00%. The Company estimates that it will record net pension expense of approximately $102 million for its U.S. defined benefit plans in 2023, compared to income of $116 million in 2022. For non-U.S. pension plans, assumptions reflect economic assumptions applicable to each country. The following illustrates the effect on pension expense for 2023 of a 25 basis point decrease in the above assumptions: In millions 2023 Expense (Income): Discount rate $ 15 Expected long-term rate of return on plan assets 20 PLAN ASSETS International Paper’s Board of Directors has appointed a Fiduciary Review Committee that is responsible for fiduciary oversight of the U.S. Pension Plan, approving investment policy and reviewing the management and control of plan assets. Pension Plan assets are invested to maximize returns within prudent levels of risk. The Pension Plan maintains a strategic asset allocation policy that designates target allocations by asset class. Investments are diversified across classes and within each class to minimize the risk of large losses. Derivatives, including swaps, forward and futures contracts, may be used as asset class substitutes or for hedging or other risk management purposes. Periodic reviews are made of investment policy objectives and investment manager performance. For non-U.S. plans, assets consist principally of common stock and fixed income securities. International Paper’s U.S. pension allocations by type of fund at December 31, 2022 and 2021 and target allocations were as follows: Asset Class 2022 2021 Target Equity accounts 16 % 18 % 14% - 25% Fixed income accounts 67 % 68 % 62% - 78% Real estate accounts 9 % 8 % 4% - 11% Other 8 % 6 % 2% - 8% Total 100 % 100 % The fair values of International Paper’s pension plan assets at December 31, 2022 and 2021 by asset class are shown below. Hedge funds disclosed in the following table are allocated to fixed income accounts for target allocation purposes.

Limited partners do not have the option to redeem partnership interests. Equity securities consist primarily of publicly traded U.S. companies and international companies. Publicly traded equities are valued at the closing prices reported in the active market in which the individual securities are traded. Fixed income consists of government securities, mortgage-backed securities, corporate bonds, common collective funds and other fixed income investments. Government securities are valued by third-party pricing sources. Mortgage-backed security holdings consist primarily of agency-rated holdings. The fair value estimates for mortgage securities are calculated by third-party pricing sources chosen by the custodian’s price matrix. Corporate bonds are valued using either the yields currently available on comparable securities of issuers with similar credit ratings or using a discounted cash flows approach that utilizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks. Common collective funds are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Other fixed income investments of $(1.1) billion and $(1.5) billion at December 31, 2022 and 2021, respectively, primarily include reverse repurchase agreement obligations in which we have sold a security and have an agreement to repurchase the same or substantially the same security at a later date for a price specified in the agreement. Derivative investments such as futures, forward contracts, options and swaps are used to help manage risks. Derivatives are generally employed as asset class substitutes (such as when employed in a portable alpha strategy), for managing asset/liability mismatches, or bona fide hedging or other appropriate risk management purposes. Derivative instruments are generally valued by the investment managers or in certain instances by third-party pricing sources. Hedge funds are investment structures for managing private, loosely-regulated investment pools that can pursue a diverse array of investment strategies with a wide range of different securities and derivative instruments. These investments are made through funds-of-funds (commingled, multi-manager fund structures) and through direct investments in individual hedge funds. Hedge funds are primarily valued by each fund’s third-party administrator based upon the valuation of the underlying securities and instruments and primarily by applying a market or income valuation methodology as appropriate depending on the specific type of security or instrument held. Funds-of-funds are valued based upon the net asset values of the underlying investments in hedge funds. Private equity consists of interests in partnerships that invest in U.S. and non-U.S. debt and equity securities. Partnership interests are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interest cash flows. Real estate funds include commercial properties, land and timberland, and generally include, but are not limited to, retail, office, industrial, multifamily and hotel properties. Real estate fund values are primarily reported by the fund manager and are based on valuation of the underlying investments which include inputs such as cost, discounted cash flows, independent appraisals and market based comparable data.

The Company continually reassesses the amount and timing of any discretionary contributions. No voluntary contributions were made in 2020, 2021 or 2022. Generally, International Paper’s non-U.S. pension plans are funded using the projected benefit as a target, except in certain countries where funding of benefit plans is not required. At December 31, 2022, projected future pension benefit payments, excluding any termination benefits, were as follows: In millions 2023 $ 610 2024 622 2025 628 2026 637 2027 640 2028-2032 3,199 OTHER U.S. PLANS International Paper sponsors the International Paper Company Salaried Savings Plan and the International Paper Company Hourly Savings Plan, both of which are tax-qualified defined contribution 401(k) savings plans. Substantially all U.S. salaried and certain hourly employees are eligible to participate and may make elective deferrals to such plans to save for retirement. International Paper makes matching contributions to participant accounts on a specified percentage of employee deferrals as determined by the provisions of each plan. The Company makes Retirement Savings Account contributions equal to a percentage of an eligible employee’s pay. Beginning in 2019, as a result of the freeze for salaried employees under the Pension Plan, all salaried employees are eligible for the contribution to the Retirement Savings Account. The Company also sponsors the International Paper Company Deferred Compensation Savings Plan, which is an unfunded nonqualified defined contribution plan. This plan permits eligible employees to continue to make deferrals and receive company matching contributions (and Retirement Savings Account contributions) when their contributions to the International Paper Salaried Savings Plan are stopped due to limitations under U.S. tax law. Participant deferrals and company contributions are not invested in a separate trust, but are paid directly from International Paper’s general assets at the time benefits become due and payable.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Defined Benefit Plan	NOTE 20 POSTRETIREMENT BENEFITS U.S. POSTRETIREMENT BENEFITS International Paper provides certain retiree health care and life insurance benefits covering certain U.S. salaried and hourly employees. These employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. International Paper does not fund these benefits prior to payment and has the right to modify or terminate certain of these plans in the future. In addition to the U.S. plan, certain Moroccan employees are eligible for retiree health care and life insurance benefits. The components of postretirement benefit expense in 2022, 2021 and 2020 were as follows: In millions 2022 2021 2020 U.S. Non- U.S. Non- U.S. Non- Service cost $ — $ — $ — $ — $ — $ — Interest cost 5 — 5 1 7 2 Actuarial loss 3 — 5 1 5 1 Amortization of prior service credits — — — (2) (1) (2) Net postretirement expense $ 8 $ — $ 10 $ — $ 11 $ 1 International Paper evaluates its actuarial assumptions annually as of December 31 (the measurement date) and considers changes in these long-term factors based upon market conditions and the requirements of employers’ accounting for postretirement benefits other than pensions. The discount rate assumption was determined based on a hypothetical settlement portfolio selected from a universe of high quality corporate bonds. The discount rates used to determine net U.S. and non-U.S. postretirement benefit cost for the years ended December 31, 2022, 2021 and 2020 were as follows: 2022 2021 2020 U.S. Non- U.S. Non- U.S. Non- Discount rate 2.90 % 5.20 % 2.50 % 6.91 % 3.30 % 7.15 % The weighted average assumptions used to determine the benefit obligation at December 31, 2022 and 2021 were as follows: 2022 2021 U.S. Non- U.S. Non- Discount rate 5.50 % 5.70 % 2.90 % 5.20 % Health care cost trend rate assumed for next year 7.25 % 4.00 % 7.00 % 4.00 % Rate that the cost trend rate gradually declines to 5.00 % 4.00 % 5.00 % 4.00 % Year that the rate reaches the rate it is assumed to remain 2032 2023 2030 2022 The plans are only funded in an amount equal to benefits paid.

Share-Based Payment Arrangement, Additional Disclosure [Abstract]
Share-based Payment Arrangement	NOTE 21 INCENTIVE PLANS International Paper currently has an Incentive Compensation Plan (ICP). The ICP authorizes grants of restricted stock, restricted or deferred stock units, performance awards payable in cash or stock upon the attainment of specified performance goals, dividend equivalents, stock options, stock appreciation rights, other stock-based awards, and cash-based awards at the discretion of the Management Development and Compensation Committee of the Board of Directors (the "Committee") that administers the ICP. Additionally, restricted stock, which may be deferred into restricted stock units (RSUs), may be awarded under a Restricted Stock and Deferred Compensation Plan for Non-Employee Directors. PERFORMANCE SHARE PLAN Under the Performance Share Plan ("PSP"), contingent awards of International Paper common stock are granted by the Committee. The PSP awards are earned over a three-year period. PSP awards are earned based on the achievement of defined performance of Return on Invested Capital ("ROIC") measured against our internal benchmark and ranking of Total Shareholder Return ("TSR") compared to the TSR peer group of companies. The 2020-2022, 2021-2023 and 2022-2024 Awards are weighted 50% ROIC and 50% TSR for all participants. The ROIC component of the PSP awards is valued at the closing stock price on the day prior to the grant date. As the ROIC component contains a performance condition, compensation expense, net of estimated forfeitures, is recorded over the requisite service period based on the most probable number of awards expected to vest. The TSR component of the PSP awards is valued using a Monte Carlo simulation as the TSR component contains a market condition. The Monte Carlo simulation estimates the fair value of the TSR component based on the expected term of the award, a risk-free rate, expected dividends, and the expected volatility for the Company and its competitors. The expected term is estimated based on the vesting period of the awards, the risk-free rate is based on the yield on U.S. Treasury securities matching the vesting period, and the volatility is based on the Company’s historical volatility over the expected term. PSP grants are made in performance-based restricted stock units. The following table sets forth the assumptions used to determine compensation cost for the market condition component of the PSP plan: Twelve Months Ended December 31, 2022 Expected volatility 24.36% - 36.92% Risk-free interest rate 0.17% - 1.61% The following summarizes PSP activity for the three years ended December 31, 2022: Share/Units Weighted Outstanding at December 31, 2019 5,514,728 $41.14 Granted 2,171,385 49.15 Shares issued (1,221,950) 51.70 Forfeited (844,138) 51.70 Outstanding at December 31, 2020 5,620,025 40.36 Granted 2,316,295 45.24 Shares issued (994,052) 63.54 Forfeited (1,016,126) 57.55 Outstanding at December 31, 2021 5,926,142 35.43 Granted 1,899,211 50.32 Shares issued (1,130,236) 40.23 Forfeited (1,382,637) 42.03 Outstanding at December 31, 2022 5,312,480 $38.01 Effective January 1, 2023, the ICP was amended to change the name of the PSP to Long-Term Incentive Plan (LTIP), which incorporates RSUs, along with tiering of performance-based stock units and RSUs. RESTRICTED STOCK AWARD PROGRAMS The service-based Restricted Stock Award program ("RSA"), designed for recruitment, retention and special recognition purposes, provides for awards of restricted stock to key employees. The following summarizes the activity of the RSA program for the three years ended December 31, 2022: Shares Weighted Outstanding at December 31, 2019 160,700 $47.27 Granted 82,228 40.12 Shares issued (83,053) 44.25 Forfeited (33,800) 46.43 Outstanding at December 31, 2020 126,075 44.83 Granted 85,098 50.90 Shares issued (85,768) 45.59 Forfeited (21,636) 45.52 Outstanding at December 31, 2021 103,769 49.03 Granted 132,200 43.38 Shares issued (104,177) 44.53 Forfeited (5,400) 47.78 Outstanding at December 31, 2022 126,392 $46.88 At December 31, 2022, 2021 and 2020 a total of 7.3 million, 7.7 million and 8.5 million shares, respectively, were available for grant under the ICP. Stock-based compensation expense and related income tax benefits were as follows: In millions 2022 2021 2020 Total stock-based compensation expense (included in selling and administrative expense) $ 124 $ 130 $ 72 Income tax benefits related to stock-based compensation 13 13 17 At December 31, 2022, $79 million of compensation cost, net of estimated forfeitures, related to unvested restricted performance shares, executive continuity awards and restricted stock attributable to future performance had not yet been recognized. This amount will be recognized in expense over a weighted-average period of 1.8 years.

Segment Reporting, Measurement Disclosures [Abstract]
Financial Information By Business Segment And Geographic Area	NOTE 22 FINANCIAL INFORMATION BY BUSINESS SEGMENT AND GEOGRAPHIC AREA International Paper’s business segments, Industrial Packaging and Global Cellulose Fibers are consistent with the internal structure used to manage these businesses. See the Description of Business Segments on pages 31 and 32 in Part II. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations for a description of the types of products and services from which each reportable segment derives its revenues. On October 1, 2021, the Company completed the previously announced spin-off of its Printing Papers business into a new, publicly-traded company, Sylvamo, listed on the New York Stock Exchange. Additionally, on August 6, 2021, the Company completed the sale of its Kwidzyn, Poland mill which included the pulp and paper mill in Kwidzyn and supporting functions. As a result of the Sylvamo spin-off and the sale of Kwidzyn, the Company no longer has a Printing Papers segment, and all prior year amounts have been adjusted to reflect the Sylvamo and Kwidzyn businesses as a discontinued operation. Both segments are differentiated on a common product, common customer basis consistent with the business segmentation generally used in the Forest Products industry. Business segment operating profits are used by International Paper’s management to measure the earnings performance of its businesses. Management believes that this measure allows a better understanding of trends in costs, operating efficiencies, prices and volumes. Business segment operating profits are defined as earnings (loss) from continuing operations before income taxes and equity earnings, but including the impact of less than wholly owned subsidiaries, excluding interest expense, net, corporate items, net, corporate net special items, business net special items and non-operating pension expense. External sales by major product is determined by aggregating sales from each segment based on similar products or services. External sales are defined as those that are made to parties outside International Paper’s consolidated group, whereas sales by segment in the Net Sales table are determined using a management approach and include intersegment sales.

Accounting Policies [Abstract]
Nature Of Business	NATURE OF BUSINESS International Paper (the "Company") is a global producer of renewable fiber-based packaging and pulp products with primary markets and manufacturing operations in North America and Europe and additional markets and manufacturing operations in Latin America, North Africa and Asia. Substantially all of our businesses have experienced, and are likely to continue to experience, cycles relating to available industry capacity and general economic conditions.
Basis of Accounting, Policy	FINANCIAL STATEMENTS These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States that require the use of management’s estimates. Actual results could differ from management’s estimates. Printing Papers Spinoff On October 1, 2021, the Company completed the previously announced spin-off of its Printing Papers segment along with certain mixed-use coated paperboard and pulp businesses in North America, France and Russia into a standalone, publicly-traded company, Sylvamo Corporation ("Sylvamo"). The transaction was implemented through the distribution of shares of the standalone company to International Paper's shareholders (the "Distribution"). As a result of the Distribution, Sylvamo is an independent public company that trades on the New York Stock Exchange under the symbol "SLVM". In addition to the spin-off of Sylvamo, the Company completed the sale of its Kwidzyn, Poland mill on August 6, 2021. All historical operating results of the Sylvamo businesses and Kwidzyn mill have been presented as Discontinued Operations, net of tax, in the consolidated statement of operations. See Note 8 - Divestitures for further details regarding the Sylvamo spin-off and discontinued operations. Russia-Ukraine Conflict The military conflict between Russia and Ukraine, including ongoing sanctions, actions by the Russian government, and associated domestic and global economic and geopolitical conditions, has adversely affected and may continue to adversely affect our Ilim joint venture and our businesses, financial condition, results of operations and cash flows. We recently
Discontinued Operations	DISCONTINUED OPERATIONS A discontinued operation may include a component or a group of components of the Company's operations. A disposal of a component or a group of components is reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on the Company's operations and financial results when the following occurs: (1) a component (or group of components) meets the criteria to be classified as held for sale; (2) the component or group of components is disposed of by sale; or (3) the component or group of components is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off).
Consolidation	CONSOLIDATION The consolidated financial statements include the accounts of International Paper and subsidiaries for which we have a controlling financial interest, including variable interest entities for which we are
Equity Method Investments	EQUITY METHOD INVESTMENTS The equity method of accounting is applied for investments when the Company has significant influence over the investee’s operations, or when the investee is structured with separate capital accounts. Our material equity method investments are described in Note 11
Asset Impairment Charges	OTHER-THAN-TEMPORARY IMPAIRMENT T he Company evaluates our equity method investments for other-than-temporary impairment (OTTI) when circumstances indicate the investment may be impaired. When a decline in fair value is deemed to be an OTTI, an impairment is recognized to the extent that the fair value is less than the carrying value of the investment. We consider various factors in determining whether a loss in value of an investment is other than temporary including: the length of time and the extent to which the fair value has been below cost, the financial condition of the investee, and our intent and ability to retain the investment for a period of time sufficient to allow for recovery of value. Management makes certain judgments and estimates in its assessment including but not limited to: identifying if circumstances indicate a decline in value is other than temporary, expectations about operations, as well as industry, financial, regulatory and market factors.
Business Combinations	BUSINESS COMBINATIONS The Company allocates the total consideration of the assets acquired and liabilities assumed based on their estimated fair value as of the business combination date. In developing estimates of fair values for long-lived assets, including identifiable intangible assets, the Company utilizes a variety of inputs including forecasted cash flows, anticipated growth rates, discount rates, estimated replacement costs and depreciation and obsolescence factors. Determining the fair value for specifically identified intangible assets such as customer lists and developed technology involves judgment. We may refine our estimates and make adjustments to the assets acquired and liabilities assumed over a measurement period, not to exceed one year. Upon the conclusion of the measurement period or the final determination of the values of assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are charged to the consolidated statement of operations. Subsequent actual results of the underlying business activity supporting the specifically identified intangible assets could change, requiring us to record impairment charges or adjust their economic lives in future periods. See Note 7 for further details.
Restructuring Liabilities and Costs	RESTRUCTURING LIABILITIES AND COSTS For operations to be closed or restructured, a liability and related expense is recorded in the period when operations cease. For termination costs associated with employees covered by a written or substantive plan, a liability is recorded when it is probable that employees will be entitled to benefits and the amount can be reasonably estimated. For termination costs associated with employees not covered by a written and broadly communicated policy covering involuntary termination benefits (severance plan), a liability is recorded for costs to terminate employees (one-time termination benefits) when the termination plan has been approved and committed to by management, the employees to be terminated have been identified, the termination plan benefit terms are communicated, the employees identified in the plan have been notified and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The timing and amount of an accrual is dependent upon the type of benefits granted, the timing of communication and other provisions that may be provided in the benefit plan. The accounting for each termination is evaluated individually. See Note 6 for further details.
Revenue Recognition	REVENUE RECOGNITION Generally, the Company recognizes revenue on a point-in-time basis when the customer takes title to the goods and assumes the risks and rewards for the goods. For customized goods where the Company has a legally enforceable right to payment for the goods, the Company recognizes revenue over time, which generally is, as the goods are produced. The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based on the most likely amount method outlined in ASC 606. The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company's portfolio of customers to record reductions in revenue that is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers. The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, recognize the incremental costs of obtaining a contract as expense when incurred if the amortization period of the asset the Company would recognize is one year or less, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 for further details.
Temporary Investments	TEMPORARY INVESTMENTS Temporary investments with an original maturity of three months or less and money market funds with greater than three month maturities but with the right to redeem without notice are treated as cash equivalents and are stated at cost, which approximates market value. See Note 9 for further details.
Inventories	INVENTORIES Inventories are valued at the lower of cost or market value and include all costs directly associated with manufacturing products: materials, labor and manufacturing overhead. In the United States, costs of raw materials and finished pulp and paper products, are generally determined using the last-in, first-out method. Other inventories are valued using the first-in, first-out or average cost methods. See Note 9 for further details.
Leased Assets	LEASED ASSETS Operating lease right of use (ROU) assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company's leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of the Company's leases, the Company applies a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate, and apply the rate based on the currency of the lease, which is updated on a quarterly basis for measurement of new lease liabilities. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases except for certain gas and chemical agreements. See Note 10 for further details.
Plants, Properties And Equipment	PLANTS, PROPERTIES AND EQUIPMENT Plants, properties and equipment are stated at cost, less accumulated depreciation. Expenditures for betterments are capitalized, whereas normal repairs and maintenance are expensed as incurred. The units-of-production method of depreciation is used for pulp and paper mills, and the straight-line method is used for other plants and equipment. See Note 9 for further details.
Goodwill	GOODWILL Annual evaluation for possible goodwill impairment is performed as of the beginning of the fourth quarter of each year, with additional interim evaluation performed when management believes that it is more likely than not, that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. The Company has the option to evaluate goodwill for impairment by first performing a qualitative assessment of events and circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amounts, then the quantitative goodwill impairment test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if the Company does not elect the option to perform an initial qualitative assessment, the Company is required to perform the quantitative goodwill impairment test. In performing this evaluation, the Company estimates the fair value of its reporting unit using a weighted approach based on discounted future cash flows, market multiples and transaction multiples. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions related to forecasts of future revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant
Impairment Of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETSLong-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that indicate that the carrying value of the assets may not be recoverable. A recoverability test is performed by comparing the undiscounted cash flows to carrying value of the assets. The inputs related to the undiscounted cash flows requires judgments as to whether assets are held and used or held for sale, the weighting of operational alternatives being considered by management and estimates of the amount and timing of expected future cash flows from the use of the long-lived assets generated by their use. If the carrying amount is less than the undiscounted cash flows, the fair value of the assets is compared to the carrying value to determine if they are impaired. We estimate fair value using discounted cash flows and other valuation techniques as needed. Impaired assets are recorded at their estimated fair value.
Income Taxes	INCOME TAXES International Paper uses the asset and liability method of accounting for income taxes whereby deferred income taxes are recorded for the future tax consequences attributable to differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are remeasured to reflect new tax rates in the periods rate changes are enacted. International Paper records its global tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in its income tax returns. Where treatment of a position is uncertain, liabilities are recorded based upon the Company’s evaluation of the “more likely than not” outcome considering technical merits of the position based on specific tax regulations and facts of each matter. Changes to recorded liabilities are only made when an identifiable event occurs that changes the likely outcome, such as settlement with the relevant tax authority, the expiration of statutes of limitation for the subject tax year, change in tax laws, or recent court cases that are relevant to the matter. Accrued interest related to these uncertain tax positions is recorded in our consolidated statement of operations in Interest expense, net. The judgments and estimates made by the Company are based on management’s evaluation of the technical merits of a matter, assisted as necessary by consultation with outside consultants, historical experience and other assumptions that management believes are appropriate and reasonable under current circumstances. Actual resolution of these matters may differ from recorded estimated amounts, resulting in adjustments that could materially affect future financial statements. See Note 13 for further details. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in assessing the need for and magnitude of appropriate valuation allowances against deferred tax assets. This assessment is completed by tax jurisdiction and relies on both positive and negative evidence available, with significant weight placed on recent financial results. Cumulative reported pre-tax income is considered objectively verifiable positive evidence of our ability to generate positive pre-tax income in the future. In accordance with GAAP, when there is a recent history of pre-tax losses, there is little or no weight placed on forecasts for purposes of assessing the recoverability of our deferred tax assets. When necessary, we use systematic and logical methods to estimate when deferred tax liabilities will reverse and generate taxable income and when deferred tax assets will reverse and generate tax deductions. Assumptions, judgment, and the use of estimates are required when scheduling the reversal of deferred tax assets and liabilities, and the exercise is inherently complex and subjective. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. International Paper uses the flow-through method to account for investment tax credits earned on eligible open-loop biomass facilities and combined heat and power system expenditures. Under this method, the investment tax credits are recognized as a reduction to income tax expense in the year they are earned rather than a reduction in the asset basis.
Environmental Remediation Costs	ENVIRONMENTAL REMEDIATION COSTS Costs associated with environmental remediation obligations are accrued when such costs are probable and reasonably estimable. Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are discounted to their present value when the amount and timing of expected cash payments are reliably determinable. See Note 14 for further details.
Translation Of Financial Statements	TRANSLATION OF FINANCIAL STATEMENTS Balance sheets of international operations are translated into U.S. dollars at year-end exchange rates, while statements of operations are translated at average rates. Adjustments resulting from financial statement translations are included as cumulative translation adjustments in Accumulated other comprehensive income (loss).
Fair Value Measurement, Policy	FAIR VALUE MEASUREMENTS The guidance for fair value measurements and disclosures sets out a fair value hierarchy that groups fair value measurement inputs into the following three classifications: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability reflecting the reporting entity’s own assumptions or external inputs from inactive markets. Transfers between levels are recognized at the end of the reporting period.
