INTERNATIONAL PAPER COMPANY

(Unaudited)

The accompanying unaudited condensed financial statements have been prepared in conformity with accounting principles generally accepted in the United States and in accordance with the instructions to Form 10-Q and, in the opinion of management, include all adjustments that are necessary for the fair presentation of International Paper Company’s (International Paper’s, the Company’s or our) financial position, results of operations, and cash flows for the interim periods presented. Except as disclosed herein, such adjustments are of a normal, recurring nature. Results for the first six months of the year may not necessarily be indicative of full year results. It is suggested that these condensed financial statements be read in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, which have previously been filed with the Securities and Exchange Commission.

Recently Adopted Accounting Pronouncements

Leases

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The Company adopted the provisions of this guidance effective January 1, 2019, using the modified retrospective optional transition method. Therefore, the standard was applied beginning January 1, 2019 and prior periods were not restated. The adoption of the standard did not result in a cumulative-effect adjustment to the opening balance of Retained earnings. The Company elected the package of practical expedients and implemented internal controls and system functionality to enable the preparation of financial information upon adoption.

The adoption of the new standard resulted in the recognition of a right of use asset and short-term and long-term liabilities recorded on the Company's consolidated balance sheet related to operating leases. Accounting for finance leases remained substantially unchanged. In addition, the adoption of the standard did not have a material impact on the Company's results of operations or cash flows.

Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This guidance gives entities the option to reclassify stranded tax effects caused by the newly-enacted U.S. Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. As a result, the Company adopted this guidance effective January 1, 2019, and recorded a net increase to opening Retained earnings and a decrease to opening Accumulated other comprehensive income of $529 million, due to the cumulative impact of adopting the new guidance.

Recently Issued Accounting Pronouncements Not Yet Adopted

Intangibles

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this guidance. This guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the provisions of this guidance.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This guidance eliminates the requirement to calculate the implied fair value of goodwill under Step 2 of today's goodwill impairment test to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. This guidance should be applied prospectively and is effective for annual reporting periods beginning after December 15, 2019, for any impairment test performed in 2020. Early adoption is

5

permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the provisions of this guidance; however, we do not anticipate adoption having a material impact on the financial statements.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This guidance replaces the current incurred loss impairment method with a method that reflects expected credit losses. This guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. This guidance should be applied using the modified-retrospective approach. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief." The amendments in this Update provide entities with targeted transition relief that is intended to increase comparability of financial statement information for some entities that otherwise would have measured similar financial instruments using different measurement methodologies. The amendments also decrease costs for some financial statement preparers while providing financial statement users with decision-useful information. For entities that have not yet adopted the amendments in Update 2016-13, the effective date and transition methodology for the amendments in this Update are the same as in Update 2016-13. The Company is currently evaluating the provisions of this guidance and plans to adopt this guidance and the related amendments on its effective date of January 1, 2020, by recognizing the cumulative effect of initially applying the new standard as an adjustment to the opening balance of Retained earnings.

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.

Revenue Contract Balances

The opening and closing balances of the Company's contract assets and current contract liabilities are as follows:

In millions	Contract Assets (Short-Term)		Contract Liabilities (Short-Term)
Beginning Balance - January 1, 2019	$	395	$	56
Ending Balance - June 30, 2019	399		40
Increase / (Decrease)	$	4	$	(16	)

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.

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 for which we have an unconditional right to payment or receive pre-payment from the customer, respectively.

Basic earnings per share is computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed assuming that all potentially dilutive securities were converted into common shares. There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share. A reconciliation of the amounts included in the computation of basic earnings (loss) per share from continuing operations, and diluted earnings (loss) per share from continuing operations is as follows: 

	Three Months Ended June 30,				Six Months Ended June 30,

2019: There were no restructuring and other charges recorded during the three months and six months ended June 30, 2019.

2018: During the three months ended June 30, 2018, the Company recorded a $26 million pre-tax charge, in the Industrial Packaging segment, related to approximately $12 million of severance, $6 million in accelerated depreciation, $2 million in accelerated amortization, and $6 million in other charges in conjunction with the optimization of our EMEA Packaging business.

During the three months ended March 31, 2018, the Company recorded a $22 million pre-tax charge, in the Industrial Packaging segment, primarily related to severance charges in conjunction with the optimization of our EMEA Packaging business.

On June 28, 2019, the Company closed on the previously announced acquisition of two packaging businesses located in Portugal (Ovar) and France (Torigni and Cabourg) from DS Smith Packaging. The total purchase consideration, inclusive of working capital adjustments, was approximately €73 million (approximately $83 million at current exchange rates), subject to post-closing adjustments.

The following table summarizes the provisional fair value assigned to assets and liabilities acquired as of June 30, 2019:

In millions	June 30, 2019
Cash and temporary investments	$	1
Accounts and notes receivable	23
Inventory	8
Plants, properties and equipment	22

Other current liabilities	1
Long-term debt	2
Postretirement and postemployment benefit obligation	3
Long-term lease obligations	2
Total liabilities assumed	29
Net assets acquired	$	83

Due to the timing of the completion of the acquisition, the purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, additional information obtained regarding assets acquired and liabilities assumed, and revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to inventory, property, plant and equipment and intangible assets. Adjustments, if any, to provisional amounts will be finalized within the adjustment period of up to one year from the acquisition date.

Pro forma information has not been included as it is impracticable to obtain the information due to the lack of availability of historical U.S. GAAP financial data and the results of the operations of these businesses do not have a material effect on the Company's consolidated results of operations.

The Company has accounted for the above acquisition under ASC 805, "Business Combinations" and the results of operations have been included in International Paper's financial statements beginning with the date of acquisition.

Discontinued Operations

On January 1, 2018, the Company completed the transfer of its North American Consumer Packaging business, which included its North American Coated Paperboard and Foodservice businesses, to Graphic Packaging International Partners, LLC (GPIP), a subsidiary of Graphic Packaging Holding Company, in exchange for a 20.5% ownership interest in GPIP. GPIP subsequently transferred the North American Consumer Packaging business to Graphic Packaging International, LLC (GPI), a wholly owned subsidiary of GPIP. International Paper is accounting for its ownership interest in the combined business under the equity method. The Company determined the fair value of its investment in the combined business and recorded a pre-tax gain of $516 million ($385 million after taxes) on the transfer in the first quarter of 2018, subject to final working capital settlement. During the second quarter of 2018, the Company recorded a pre-tax charge of $28 million ($21 million after taxes) to adjust the previously recorded gain on the transfer. 

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 transfer of the North American Consumer Packaging business for all periods presented in the consolidated statement of operations:

Other Divestitures

On May, 29, 2019, the Company announced that it had entered into an agreement with West Coast Paper Mills Limited (WCPM) to sell its controlling interest in International Paper APPM Limited (APPM), an India-based paper business, for ₨275 (Indian Rupees) per share. International Paper currently owns approximately 30 million shares, or 75% of the outstanding shares of APPM. The transaction is expected to be completed by the end of the year subject to satisfaction of customary closing conditions, including obtaining required governmental approvals and WCPM's launch of a tender offer. Once this transaction closes, WCPM will be responsible for the operations of APPM, and International Paper will be a passive investor until such time that IP has sold its remaining share in APPM.

In conjunction with the announced agreement, a determination was made that the current book value of the APPM disposal group exceeded its estimated fair value of $119 million which was based on the agreed upon transaction price. As a result, a preliminary pre-tax charge of $152 million ($150 million after taxes) was recorded during the second quarter of 2019. This charge included $95 million related to the cumulative foreign currency translation loss and a $57 million loss related to the write down of the long-lived assets of APPM to their estimated fair value. This charge is included in the Net (gains) losses on sales and impairments of businesses in the accompanying consolidated statement of operations and is included in the results for the Printing Papers segment. A loss of $7 million (before and after taxes) has been allocated to the noncontrolling interest related to the impairment of the long-lived assets of APPM.

Asset Retirement Obligations

The Company had recorded liabilities of $95 million and $86 million related to asset retirement obligations at June 30, 2019 and December 31, 2018, respectively.

International Paper leases various real estate, including certain operating facilities, warehouses, office space and land. The Company also leases material handling equipment, vehicles, and certain other equipment. The Company's leases have remaining lease terms of one year to 97 years. 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.

Right of use (ROU) assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Effective January 1, 2019, operating lease 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.

The Company accounts for the following investments in affiliated companies under the equity method of accounting.

Graphic Packaging International Partners, LLC

On January 1, 2018, the Company completed the transfer of its North American Consumer Packaging business, which included its North American Coated Paperboard and Foodservice businesses, to a subsidiary of Graphic Packaging International Partners, LLC (GPIP), a subsidiary of Graphic Packaging Holding Company, in exchange for a 20.5% ownership interest in GPIP. GPIP subsequently transferred the North American Consumer Packaging business to Graphic Packaging International, LLC (GPI), a wholly-owned subsidiary of GPIP that holds the assets of the combined business. The Company recorded equity earnings of $14 million and $15 million for the three months ended June 30, 2019 and 2018, respectively, and $27 million and $17 million for the six months ended June 30, 2019 and 2018, respectively. The Company received cash dividends from GPIP of $12 million and $6 million during the first six months of 2019 and 2018, respectively. The Company's investment in GPIP was $1.1 billion at both June 30, 2019 and December 31, 2018, which was $565 million and $562 million, respectively, more than the Company's proportionate share of the entity's underlying net assets. The difference primarily relates to the basis difference between the fair value of our investment and the underlying net assets, and is generally amortized in equity earnings over a period consistent with the underlying long-lived assets. The Company is party to various agreements with GPI under which it sells fiber and other products to GPI. Sales under these agreements were $74 million and $58 million for the three months ended June 30, 2019 and 2018, respectively, and $143 million and $118 million for the six months ended June 30, 2019 and 2018, respectively.

At June 30, 2019 and December 31, 2018, the Company's investment in Ilim was $466 million and $478 million, respectively, which was $149 million and $145 million, respectively, more than the Company's proportionate share of the joint venture's underlying net assets. The differences primarily relate to currency translation adjustments and the basis difference between the fair value of our investment at acquisition and the underlying net assets. The Company is party to a joint marketing agreement with JSC Ilim Group, a subsidiary of Ilim, under which the Company purchases, markets and sells paper produced by JSC Ilim Group. Purchases under this agreement were $59 million and $56 million for the three months

International Paper made income tax payments, net of refunds, of $97 million and $112 million for the six months ended June 30, 2019 and 2018, respectively.

The Company currently estimates, that as a result of ongoing discussions, pending tax settlements and expirations of statutes of limitations, the amount of unrecognized tax benefits could be reduced by approximately $35 million during the next 12 months.

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. The Company recorded a tax benefit of $6 million for each of the six months ended June 30, 2019 and 2018, respectively.

The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by International Paper do Brasil Ltda., a wholly-owned subsidiary of the Company. The Company received assessments for the tax years 2007-2015 totaling approximately $146 million in tax, and $377 million in interest and penalties as of June 30, 2019 (adjusted for variation in currency exchange rates). After a previous favorable ruling challenging the basis for these assessments, we received an unfavorable decision in October 2018 from the Brazilian Administrative Council of Tax Appeals. The Company has appealed this judgment to the Brazilian federal courts; however, this tax litigation matter may take many years to resolve. The Company believes that it has appropriately evaluated the transaction underlying these assessments, and has concluded based on Brazilian tax law, that its position would be sustained. The Company intends to vigorously defend its position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015.

Environmental

International Paper 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 or formerly-owned facilities, and recorded as liabilities in the balance sheet.

20

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 matters to be approximately $132 million ($142 million undiscounted) in the aggregate as of June 30, 2019. Other than as described below, completion of required remedial actions is not expected to have a material effect on our consolidated financial statements.

Cass Lake: One of the matters included above arises out of a closed wood-treating 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. The overall remediation reserve for the site is currently $48 million to address the selection of an alternative for the soil remediation component of the overall site remedy, which includes the ongoing groundwater remedy. In October 2011, the EPA released a public statement indicating that the final soil remedy decision would be delayed. In June 2019, the EPA issued a revised proposed plan concerning clean-up standards at a portion of the site, the estimated cost of which is included within the reserve referenced above. In October 2012, the Natural Resource Trustees for this site provided notice to International Paper and other PRPs of their intent to perform a Natural Resource Damage Assessment. It is premature to predict the outcome of the assessment or to estimate a loss or range of loss, if any, which may be incurred.

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 (the Allied Paper Mill) formerly owned by St. Regis Paper Company (St. Regis). The Company is a successor in interest to St. Regis.

• 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.

• In April 2016, the EPA issued a separate unilateral administrative order to the Company and certain other PRPs for a time-critical removal action (TCRA) of PCB-contaminated sediments from a different portion of the site. The Company responded to the unilateral administrative order and agreed along with two other parties to comply with the order subject to its sufficient cause defenses.

• In October 2016, the Company and another PRP received a special notice letter from the EPA inviting participation in the remedial design component of the landfill remedy for the Allied Paper Mill. The record of decision 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 remedial design.

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 with respect to this site. However, we do not believe that any material loss is probable.

The Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC in a contribution and cost recovery action for alleged pollution at the site. 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. The suit alleges that a mill, during the time it was allegedly owned and operated by St. Regis, discharged PCB contaminated solids and paper residuals resulting from paper de-inking and recycling. NCR Corporation and Weyerhaeuser Company are also named as defendants in the suit. In mid-2011, the suit was transferred from the District Court for the Eastern District of Wisconsin to the District Court for the Western District of Michigan.

The trial of the initial liability phase took place in February 2013. Weyerhaeuser conceded prior to trial that it was a liable party with respect to the site. In September 2013, an opinion and order was issued in the suit. The order concluded that the Company (as the successor to St. Regis) was not an “operator,” but was an “owner,” of the mill at issue during a portion of the relevant period and is therefore liable under CERCLA. The order also determined that NCR is a liable party as an "arranger for disposal" of PCBs in waste paper that was de-inked and recycled by mills along the Kalamazoo River. The order did not address the Company's responsibility, if any, for past or future costs. The parties’ responsibility, including that of the Company,

21

was the subject of a second trial, which was concluded in late 2015. 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. As to future remediation costs, we remain unable to estimate our maximum reasonably possible loss with respect to this site. However, we do not believe that any material loss is probable.

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 September 2016, the EPA issued a proposed remedial action plan (PRAP) for the site, which identified the preferred remedy as the removal of the contaminated material currently protected by an armored cap. In addition, the EPA selected a preferred remedy for the separate southern impoundment that requires offsite disposal. In January 2017, the PRPs submitted comments on the PRAP.

On October 11, 2017, the EPA issued a Record of Decision (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. While the EPA’s selected remedy was accompanied by a cost estimate of approximately $115 million, we do not believe that estimate provides a reasonable basis for accrual under GAAP because the estimate was based on a technological method for performing the work that we believe is not feasible. 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 over the subsequent 29 months. 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.

The Company has identified a number of concerns and uncertainties regarding the remedy described in the ROD and regarding the EPA’s estimates for the costs and time required to implement the selected remedy. The Company has determined, however, that even if the ROD cannot be implemented, a sheet pile "engineered barrier" can be constructed, which would enhance the existing remedy and could also be used should the ROD be determined to be feasible and implementable. In the third quarter of 2018, we increased our recorded liability accordingly to reflect the estimated cost of constructing this barrier. Because of ongoing questions regarding cost effectiveness, technical feasibility, timing and other technical data, however, it is uncertain how the ROD will be implemented. Consequently, while additional losses are probable as a result of the selected remedy, we are currently unable to determine any further adjustment to our immaterial recorded liability. It remains reasonably possible that additional losses could be material as the remedial design process with the EPA continues over the coming quarters.

International Paper and MIMC/WMI are also defending an additional lawsuit related to the site brought by approximately 600 individuals who allege property damage and personal injury. Because this case is still in the discovery phase, it is premature to predict the outcome or to estimate a loss or range of loss, if any, which may be incurred.

Antitrust

Containerboard: In January 2011, International Paper was named as a defendant in a lawsuit filed in state court in Cocke County, Tennessee alleging that International Paper violated Tennessee law by conspiring to limit the supply and fix the prices of containerboard from mid-2005 to the present. Plaintiffs in the state court action seek certification of a class of Tennessee indirect purchasers of containerboard products, damages and costs, including attorneys' fees. No class certification materials have been filed to date in the Tennessee action. The Company disputes the allegations made in the Tennessee lawsuit and is vigorously defending it. At this time, however, because the action is in a preliminary stage, we are unable to predict an outcome or estimate a range of reasonably possible loss.

Contract

Signature: In August 2014, a lawsuit captioned Signature Industrial Services LLC et al. v. International Paper Company was filed in state court in Texas. The Signature lawsuit arises out of approximately $1 million in disputed invoices related to the installation of new equipment at the Company's Orange, Texas mill. In addition to the invoices in dispute, Signature and its

22

president allege consequential damages arising from the Company's nonpayment of those invoices. The lawsuit was tried before a jury in Beaumont, Texas, in May 2017. On June 1, 2017, the jury returned a verdict awarding approximately $125 million in damages to the plaintiffs. The Court issued a judgment on December 14, 2017, awarding the plaintiffs a total of approximately $137 million in actual and consequential damages, fees, costs and pre-judgment interest, and awarding post-judgment interest. The Company has appealed this judgment. The Company has presented in its briefing numerous and strong bases for appeal, and we believe we will prevail on appeal. Because the appellate proceedings are ongoing, we are unable to estimate a range of reasonably possible loss, but we expect the amount of any loss to be immaterial.

General

The Company is involved in various other inquiries, administrative proceedings and litigation relating to environmental and safety matters, personal injury, labor and employment, contracts, sales of property, intellectual property, tax, antitrust and other matters, some of which allege substantial monetary damages. While any proceeding or litigation has the element of uncertainty, the Company believes that the outcome of any of these other lawsuits or claims that are pending or threatened or all of them combined (other than those that cannot be assessed due to their preliminary nature) will not have a material effect on its consolidated financial statements. See Note 14 for details regarding a tax matter.

In June 2019, International Paper issued $200 million of 3.55% senior unsecured notes with a maturity date in 2029. The proceeds from this offering, together with a combination of available cash and other borrowings, were used for general corporate purposes, including repayment of outstanding commercial paper borrowings and other existing indebtedness.

In June 2018, the borrowing capacity of International Paper's commercial paper program was increased from $750 million to $1.0 billion. Under the terms of the 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. As of June 30, 2019, the Company had $535 million of borrowings outstanding under the program at a weighted average interest rate of 2.64%.

At June 30, 2019, the fair value of International Paper’s $10.7 billion of debt was approximately $11.4 billion. The fair value of the Company’s long-term debt is estimated based on the quoted market prices for the same or similar issues. International Paper’s long-term debt is classified as Level 2 within the fair value hierarchy, which is further defined in Note 16 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

As a multinational company International Paper is exposed to market risks, such as changes in interest rates, currency exchange rates and commodity prices.

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 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.

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 substantially all U.S. salaried employees and hourly employees (receiving salaried benefits) hired prior to July 1, 2004, and substantially all other U.S. hourly and union employees who work at a participating business unit regardless of hire date. These employees generally are eligible to participate in the Pension Plan upon attaining 21 years of age and completing one year of eligibility service. U.S. salaried employees and hourly employees (receiving salaried benefits) hired after June 30, 2004, are not eligible for the Pension Plan, but receive a company contribution to their Retirement Savings Account under the International Paper Company Salaried Savings Plan; however, salaried employees hired by Temple Inland prior to March 1, 2007 or Weyerhaeuser Company's Cellulose Fibers division prior to December 1, 2011 also participate in the Pension Plan.

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).

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 will instead receive a company contribution to their individual Retirement Savings Account.

Net periodic pension expense for our qualified and nonqualified U.S. defined benefit plans comprised the following: 

	Three Months Ended June 30,						Six Months Ended June 30,
In millions	2019			2018			2019			2018
Service cost	$	16		$	41		$	34		$	79

Amortization of prior service cost	4			4			8			8
Net periodic pension expense	$	21		$	73		$	47		$	115

The components of net periodic pension expense other than the Service cost component are included in Non-operating pension expense in the Consolidated Statement of Operations.

The Company’s funding policy for our pension plans is to contribute amounts sufficient to meet legal funding requirements, plus any additional amounts that the Company may determine to be appropriate considering the funded status of the plan, tax deductibility, the cash flows generated by the Company, and other factors. The Company made no voluntary cash contributions to the qualified pension plan in the first six months of 2019 or 2018. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $10 million for the six months ended June 30, 2019.

International Paper has an Incentive Compensation Plan (ICP) which is administered by the Management Development and Compensation Committee of the Board of Directors (the Committee). The ICP authorizes the 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 Committee. As of June 30, 2019, 9.7 million shares were available for grant under the ICP.

Stock-based compensation expense and related income tax benefits were as follows: 

	Three Months Ended June 30,					Six Months Ended June 30,
In millions	2019			2018		2019		2018
Total stock-based compensation expense (selling and administrative)	$	36		$	36	$	63	$	67

At June 30, 2019, $159 million, net of estimated forfeitures, of compensation cost related to unvested restricted performance shares, executive continuity awards and restricted stock attributable to future service had not yet been recognized. This amount will be recognized in expense over a weighted-average period of 1.9 years.

Performance Share Plan

During the first six months of 2019, the Company granted 2.4 million performance units at an average grant date fair value of $43.49.

International Paper’s business segments, Industrial Packaging, Global Cellulose Fibers and Printing Papers, are consistent with the internal structure used to manage these businesses. All 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 equity earnings and noncontrolling interests, excluding interest expense, net, corporate expenses, net, corporate special items, net and non-operating pension expense.

Sales by business segment for the three months and six months ended June 30, 2019 and 2018 were as follows:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EXECUTIVE SUMMARY

Net earnings (loss) attributable to International Paper common shareholders were $292 million ($0.73 per diluted share) in the second quarter of 2019, compared with $424 million ($1.05 per diluted share) in the first quarter of 2019 and $405 million ($0.97 per diluted share) in the second quarter of 2018. Adjusted Operating Earnings is a non-GAAP measure and is defined as net earnings from continuing operations (a GAAP measure) excluding special items and non-operating pension expense. International Paper generated Adjusted Operating Earnings Attributable to International Paper Common Shareholders of $460 million ($1.15 per diluted share) in the second quarter of 2019, compared with $447 million ($1.11 per diluted share) in the first quarter of 2019 and $498 million ($1.19 per diluted share) in the second quarter 2018.

International Paper delivered solid earnings and strong cash generation in the second quarter of 2019. Our second quarter performance demonstrates our ability to leverage our system flexibility to deliver solid results in a more challenging environment. Box shipments were seasonally stronger versus the first quarter but weaker than expected, with soft demand in certain non-food segments for non-durable goods. Our export containerboard and pulp businesses saw lower volume in the second quarter driven by uneven global demand and high inventory levels. In spite of these challenges, operational performance was strong and we managed costs well across our businesses as we executed our highest maintenance outage quarter of the year. We continued to generate strong cash flows in the second quarter with cash from operations of approximately $1.1 billion and free cash flow of $732 million, including a $239 million cash dividend from our Ilim joint venture. This strong cash flow has enabled us to return about $810 million to shareholders through dividends and share repurchases during the first half of 2019.

Comparing performance with the first quarter of 2019, price and mix were lower in the second quarter mainly due to lower export containerboard and pulp prices, which were partially offset by higher prices in our North American Printing Papers business. Volume increased on seasonally stronger demand in our North American container and Brazil Papers businesses, which was partly offset by lower export containerboard and pulp volume. Operations and cost performance was strong. We ran our system well and managed costs effectively to mitigate the impact of downtime taken in the second quarter. We also successfully executed our highest maintenance outage quarter of the year and have now completed approximately 75% of our planned annual outages of 2019. Input costs were favorable versus the prior quarter, with lower recovered fiber and energy costs across our businesses, as well as lower wood costs, following a steep run up in 2018 and the first quarter of 2019. Our Ilim joint venture delivered solid earnings and operational performance. Ilim equity earnings decreased due to lower average pulp prices and higher planned maintenance outage expenses in the second quarter, as well as lower sequential non-cash, foreign exchange gains on Ilim’s U.S. dollar denominated net debt.

Looking ahead to the third quarter of 2019, across our businesses we expect lower price and mix, improved seasonal volume and export shipments, lower input costs and significantly lower maintenance outages following the heavy first half activity. In Industrial Packaging, we expect lower price and mix due to the impact of prior price index movements and continued export pressure. Volume is expected to improve on seasonally stronger demand in North America and improved export containerboard demand, with inventory destocking progressing as expected in overseas markets. Operations and costs are expected to be unfavorably impacted by higher seasonal labor costs in the North America box system. Maintenance outage expense will be lower, and we anticipate lower input costs for fiber and energy. In Global Cellulose Fibers, we expect lower price and mix due to continued trade and tariff uncertainty and high pulp inventory levels. Operations and costs are also expected to negatively impact earnings in the quarter due to the non-repeat of hurricane-related insurance recovery in the second quarter along with higher unabsorbed fixed costs. Earnings will benefit from lower maintenance outage expense along with lower input costs, primarily wood costs. In Printing Papers, we expect lower price and mix primarily related to export pressure in Latin America and geographic mix. This should be offset by improved volume on seasonally stronger demand in North America and Brazil. Printing Papers will also benefit from lower maintenance outage expenses in the quarter. Finally, in our Ilim joint venture, we expect lower average pulp prices and higher maintenance outage expenses in the third quarter, along with the non-repeat of the foreign exchange gain on Ilim’s U.S. dollar denominated net debt.

Adjusted Operating Earnings and Adjusted Operating Earnings Per Share are non-GAAP measures and are defined as net earnings from continuing operations (a GAAP measure) excluding special items and non-operating pension expense. Net earnings (loss) and Diluted earnings (loss) per share attributable to common shareholders are the most directly comparable GAAP measures. The Company calculates Adjusted Operating Earnings by excluding the after-tax effect of non-operating pension expense, items considered by management to be unusual, and discontinued operations from the earnings reported under GAAP. Adjusted Operating Earnings Per Share is calculated by dividing Adjusted Operating Earnings by diluted average shares of common stock outstanding. Management uses this measure to focus on on-going operations, and believes that it is useful to

29

investors because it enables them to perform meaningful comparisons of past and present consolidated operating results. The Company believes that using this information, along with the most directly comparable GAAP measure, provides for a more complete analysis of the results of operations.

The following are reconciliations of Earnings (loss) attributable to shareholders to Adjusted Operating Earnings (Loss) attributable to shareholders.

The Company generated free cash flow of approximately $1.2 billion and $535 million in the first six months of 2019 and 2018, respectively. Free cash flow is a non-GAAP measure and the most directly comparable GAAP measure is cash provided by operations. Management believes that free cash flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. By adjusting for certain items that are not indicative of the Company's ongoing performance, free cash flow also enables investors to perform meaningful comparisons between past and present periods.

The following is a reconciliation of cash provided by operations to free cash flow:

Cash provided by operations	$	1,800		$	1,464

For the second quarter of 2019, International Paper Company reported net sales of $5.7 billion, compared with $5.6 billion in the first quarter of 2019 and $5.8 billion in the second quarter of 2018.

Net earnings attributable to International Paper totaled $292 million, or $0.73 per diluted share, in the 2019 second quarter. This compared with $424 million, or $1.05 per diluted share, in the first quarter of 2019 and $405 million, or $0.97 per diluted share, in the second quarter of 2018.

Earnings from continuing operations attributable to International Paper Company were $292 million in the second quarter of 2019, $424 million in the first quarter of 2019 and $428 million in the second quarter of 2018.

Compared with the first quarter of 2019, earnings benefited from higher sales volumes ($17 million), lower operating costs ($63 million), lower raw material and freight costs ($49 million), lower corporate and other items ($14 million), lower net interest expense ($9 million), lower tax expense ($2 million) and lower non-operating pension expense ($2 million). These benefits were offset by lower average sales prices, net of a favorable mix ($26 million), and higher mill maintenance outage costs ($81 million). Equity earnings, net of taxes, relating to International Paper’s investments in Ilim S.A., Graphic Packaging International Partners, LLC, and other investments were $34 million lower than in the first quarter of 2019. Net special items in the second quarter of 2019 were a loss of $162 million compared with a loss of $15 million in the first quarter of 2019.

31

Compared with the second quarter of 2018, the second quarter of 2019 reflects higher average sales prices, net of an unfavorable mix ($71 million), lower corporate and other costs ($20 million), lower net interest expense ($9 million), lower tax expense ($1 million) and lower non-operating pension expense ($21 million). These benefits were offset by lower sales volumes ($48 million), higher operating costs ($43 million), higher raw material and freight costs ($22 million) and higher mill maintenance outage costs ($36 million). Equity earnings, net of taxes, relating to International Paper’s investments in Ilim S.A., Graphic Packaging International Partners, LLC, and other investments were $10 million higher in the second quarter of 2019 than in the second quarter of 2018. Net special items in the second quarter of 2019 were a loss of $162 million compared with a loss of $43 million in the second quarter of 2018.

Business Segment Operating Profits are used by International Paper's management to measure the earnings performance of its businesses. Management uses this measure to focus on on-going operations, and believes that it is useful to investors because it enables them to perform meaningful comparisons of past and present operating results. International Paper believes that using this information, along with net earnings, provides a more complete analysis of the results of operations by quarter. Business Segment Operating Profits are defined as earnings (loss) from continuing operations before income taxes and equity earnings, but including the impact of equity earnings and noncontrolling interests, and excluding interest expense, net, corporate expenses, net, corporate special items, net and non-operating pension expense.

International Paper operates in three segments: Industrial Packaging, Global Cellulose Fibers and Printing Papers.

Compared with the first quarter of 2019, operating profits benefited from higher sales volumes ($23 million), lower operating costs ($85 million) and lower raw material and freight costs ($65 million). These benefits were offset by lower average sales prices, net of a favorable mix ($35 million) and higher mill outage costs ($109 million). Special items were a loss of $157 million in the second quarter of 2019 compared with a loss of $21 million in the first quarter of 2019.

34

Compared with the second quarter of 2018, operating profits in the current quarter benefited from higher average sales prices net of an unfavorable mix ($96 million). These benefits were offset by lower sales volumes ($64 million), higher operating costs ($57 million), higher raw material and freight costs ($30 million) and higher mill outage costs ($48 million). Special items were a loss of $157 million in the second quarter of 2019 compared with a loss of $35 million in the second quarter of 2018.

Economic downtime results from the amount of production required to meet our customer demand. Planned maintenance downtime is taken periodically throughout the year. The following table details North American planned maintenance and economic-related downtime (in tons):

The following tables present net sales and operating profit (loss) which is the Company's measure of segment profitability. The tables include a detail of special items in each year, where applicable, in order to show operating profit before special items. The Company calculates Operating Profit Before Special Items (non-GAAP) by excluding the pre-tax effect of items considered by management to be unusual from the earnings reported under U.S. generally accepted accounting principles (GAAP). Management uses this measure to focus on on-going operations, and believes that it is useful to investors because it enables them to perform meaningful comparisons of past and present operating results. International Paper believes that using this information, along with net earnings, provides for a more complete analysis of the results of operations by quarter. Net earnings attributable to International Paper is the most directly comparable GAAP measure. See Note 21 - Business Segment Information in the Condensed Notes to the Consolidated Financial Statements for the GAAP reconciliation of segment operating profit.

North American Industrial Packaging sales volumes in the second quarter of 2019 increased compared to the first quarter of 2019, reflecting seasonally higher shipments for boxes, partially offset by lower export containerboard volumes as customer destocking continued. Total maintenance and economic downtime was 10,000 tons higher in the second quarter of 2019, which comprises an increase of 92,000 tons for planned maintenance downtime and a decrease of 82,000 tons for economic downtime. Economic downtime was driven by lower volumes as we continued to manage production to meet our customers' needs. Average sales margins were lower, driven by lower average sales prices for export containerboard. Manufacturing performance was strong in both our mills and box plants and we continued to manage costs well to mitigate the impact of downtime in the quarter. Planned maintenance downtime costs were $27 million higher in the second quarter of 2019 compared with the first quarter of 2019, with 80% of our annual planned outages now complete. Input costs were significantly favorable, primarily for recycled fiber, energy, wood and distribution.

Compared with the second quarter of 2018, sales volumes were lower in the second quarter of 2019 for export containerboard and boxes, partially due to one less shipping day in 2019. Total maintenance and economic downtime was 376,000 tons higher in the second quarter of 2019, which comprises an increase of 48,000 tons for planned maintenance downtime and 328,000 tons for economic downtime. Average sales prices for boxes were higher, due to carryover of the Spring 2018 sales price increase. Export containerboard prices were lower, reflecting weaker demand. Manufacturing costs were lower, driven by strong operational performance at our mills. Planned maintenance downtime costs were $9 million higher in the second quarter of 2019 compared with the second quarter of 2018. Input costs for recycled fiber and energy were lower, partially offset by higher costs for wood.

Entering the third quarter of 2019, sales volumes for boxes are expected to be higher. Containerboard export shipments are also expected to increase, as demand improves and customers begin to replenish inventory. Average sales prices for boxes and export containerboard are expected to be lower, reflecting the impact of prior index movement, mix and export pressure. Operating costs are expected to be seasonally higher. Planned maintenance downtime costs should be $63 million lower in the third quarter of 2019 than in the second quarter of 2019. Input costs are projected to be lower, primarily for wood.

EMEA Industrial Packaging sales volumes for boxes in the second quarter of 2019 were lower than in the first quarter of 2019 primarily due to lower seasonal demand in Morocco. Average sales margins improved in all regions driven by lower containerboard prices and stable box prices. Manufacturing operations improved, reflecting improved performance at the Madrid mill and the benefits of our box system optimization initiatives. Earnings also benefited from the box plant acquisitions completed in the first quarter of 2019.

International Paper expects to be able to meet projected capital expenditures, service existing debt and meet working capital and dividend requirements during the remainder of 2019 with current cash balances and cash from operations, supplemented as required by its existing credit facilities. The Company will continue to rely on debt and capital markets for the majority of any necessary long-term funding not provided by operating cash flows. Funding decisions will be guided by our capital structure planning objectives. The primary goals of the Company’s capital structure planning are to maximize financial flexibility and preserve liquidity while reducing interest expense. The majority of International Paper’s debt is accessed through global public capital markets where we have a wide base of investors.

Ilim S.A. Shareholders’ Agreement

In October 2007, in connection with the formation of the Ilim S.A. joint venture (Ilim), International Paper entered into a shareholders' agreement that includes provisions relating to the reconciliation of disputes among the partners. This agreement provides that at any time, either the Company or its partners may commence procedures specified under the deadlock agreement. If these or any other deadlock procedures under the shareholders' agreement are commenced, although it is not obligated to do so, the Company may in certain situations choose to purchase its partners' 50% interest in Ilim. Any such transaction would be subject to review and approval by Russian and other relevant anti-trust authorities. Based on the provisions of the agreement, the Company estimates that the current purchase price for its partners' 50% interests would be approximately $2.3 billion, which could be satisfied by payment of cash or International Paper common stock, or some combination of the two, at the Company's option. The purchase by the Company of its partners’ 50% interest in Ilim would result in the consolidation of Ilim's financial position and results of operations in all subsequent periods. The parties have informed each other that they have no current intention to commence procedures specified under the deadlock provisions of the shareholders' agreement.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires International Paper to establish accounting policies and to make estimates that affect both the amounts and timing of the recording of assets, liabilities, revenues and expenses. Some of these estimates require judgments about matters that are inherently uncertain.

Accounting policies whose application may have a significant effect on the reported results of operations and financial position of International Paper, and that can require judgments by management that affect their application, include accounting for contingencies, impairment or disposal of long-lived assets, goodwill and other intangible assets, pensions and income taxes.

The Company has included in its 2018 Form 10-K a discussion of these critical accounting policies, which are important to the portrayal of the Company’s financial condition and results of operations and require management’s judgments. The Company has not made any changes in these critical accounting policies during the first six months of 2019.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (Exchange Act), is recorded, processed, summarized and reported (and accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure) within the time periods specified in the Securities and Exchange Commission’s rules and forms. As of the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2019 (the end of the period covered by this report).

Changes in Internal Control over Financial Reporting:

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

RECENT ACCOUNTING DEVELOPMENTS Footnote

Jun. 30, 2019

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Developments [Note Text Block]

Recently Adopted Accounting Pronouncements

Leases

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The Company adopted the provisions of this guidance effective January 1, 2019, using the modified retrospective optional transition method. Therefore, the standard was applied beginning January 1, 2019 and prior periods were not restated. The adoption of the standard did not result in a cumulative-effect adjustment to the opening balance of Retained earnings. The Company elected the package of practical expedients and implemented internal controls and system functionality to enable the preparation of financial information upon adoption.

The adoption of the new standard resulted in the recognition of a right of use asset and short-term and long-term liabilities recorded on the Company's consolidated balance sheet related to operating leases. Accounting for finance leases remained substantially unchanged. In addition, the adoption of the standard did not have a material impact on the Company's results of operations or cash flows.

Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This guidance gives entities the option to reclassify stranded tax effects caused by the newly-enacted U.S. Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. As a result, the Company adopted this guidance effective January 1, 2019, and recorded a net increase to opening Retained earnings and a decrease to opening Accumulated other comprehensive income of $529 million, due to the cumulative impact of adopting the new guidance.

Recently Issued Accounting Pronouncements Not Yet Adopted

Intangibles

In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this guidance. This guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the provisions of this guidance.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This guidance eliminates the requirement to calculate the implied fair value of goodwill under Step 2 of today's goodwill impairment test to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. This guidance should be applied prospectively and is effective for annual reporting periods beginning after December 15, 2019, for any impairment test performed in 2020. Early adoption is

permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the provisions of this guidance; however, we do not anticipate adoption having a material impact on the financial statements.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This guidance replaces the current incurred loss impairment method with a method that reflects expected credit losses. This guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. This guidance should be applied using the modified-retrospective approach. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief." The amendments in this Update provide entities with targeted transition relief that is intended to increase comparability of financial statement information for some entities that otherwise would have measured similar financial instruments using different measurement methodologies. The amendments also decrease costs for some financial statement preparers while providing financial statement users with decision-useful information. For entities that have not yet adopted the amendments in Update 2016-13, the effective date and transition methodology for the amendments in this Update are the same as in Update 2016-13. The Company is currently evaluating the provisions of this guidance and plans to adopt this guidance and the related amendments on its effective date of January 1, 2020, by recognizing the cumulative effect of initially applying the new standard as an adjustment to the opening balance of Retained earnings.

REVENUE RECOGNITION Footnote

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

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.

Disaggregated Revenue

Revenue Contract Balances

The opening and closing balances of the Company's contract assets and current contract liabilities are as follows:

In millions	Contract Assets (Short-Term)		Contract Liabilities (Short-Term)
Beginning Balance - January 1, 2019	$	395	$	56
Ending Balance - June 30, 2019	399		40
Increase / (Decrease)	$	4	$	(16	)

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.

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 for which we have an unconditional right to payment or receive pre-payment from the customer, respectively.

Basic earnings per share is computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed assuming that all potentially dilutive securities were converted into common shares. There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share. A reconciliation of the amounts included in the computation of basic earnings (loss) per share from continuing operations, and diluted earnings (loss) per share from continuing operations is as follows:

Business Combinations [Abstract]

Business Combination Disclosure [Text Block]

On June 28, 2019, the Company closed on the previously announced acquisition of two packaging businesses located in Portugal (Ovar) and France (Torigni and Cabourg) from DS Smith Packaging. The total purchase consideration, inclusive of working capital adjustments, was approximately €73 million (approximately $83 million at current exchange rates), subject to post-closing adjustments.

The following table summarizes the provisional fair value assigned to assets and liabilities acquired as of June 30, 2019:

In millions	June 30, 2019
Cash and temporary investments	$	1
Accounts and notes receivable	23
Inventory	8
Plants, properties and equipment	22
Goodwill	56
Right of use assets	2
Total assets acquired	112
Accounts payable and accrued liabilities	21
Other current liabilities	1
Long-term debt	2
Postretirement and postemployment benefit obligation	3
Long-term lease obligations	2
Total liabilities assumed	29
Net assets acquired	$	83

Due to the timing of the completion of the acquisition, the purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, additional information obtained regarding assets acquired and liabilities assumed, and revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to inventory, property, plant and equipment and intangible assets. Adjustments, if any, to provisional amounts will be finalized within the adjustment period of up to one year from the acquisition date.

Pro forma information has not been included as it is impracticable to obtain the information due to the lack of availability of historical U.S. GAAP financial data and the results of the operations of these businesses do not have a material effect on the Company's consolidated results of operations.

The Company has accounted for the above acquisition under ASC 805, "Business Combinations" and the results of operations have been included in International Paper's financial statements beginning with the date of acquisition.

On January 1, 2018, the Company completed the transfer of its North American Consumer Packaging business, which included its North American Coated Paperboard and Foodservice businesses, to Graphic Packaging International Partners, LLC (GPIP), a subsidiary of Graphic Packaging Holding Company, in exchange for a 20.5% ownership interest in GPIP. GPIP subsequently transferred the North American Consumer Packaging business to Graphic Packaging International, LLC (GPI), a wholly owned subsidiary of GPIP. International Paper is accounting for its ownership interest in the combined business under the equity method. The Company determined the fair value of its investment in the combined business and recorded a pre-tax gain of $516 million ($385 million after taxes) on the transfer in the first quarter of 2018, subject to final working capital settlement. During the second quarter of 2018, the Company recorded a pre-tax charge of $28 million ($21 million after taxes) to adjust the previously recorded gain on the transfer. 

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 transfer of the North American Consumer Packaging business for all periods presented in the consolidated statement of operations:

Other Divestitures

On May, 29, 2019, the Company announced that it had entered into an agreement with West Coast Paper Mills Limited (WCPM) to sell its controlling interest in International Paper APPM Limited (APPM), an India-based paper business, for ₨275 (Indian Rupees) per share. International Paper currently owns approximately 30 million shares, or 75% of the outstanding shares of APPM. The transaction is expected to be completed by the end of the year subject to satisfaction of customary closing conditions, including obtaining required governmental approvals and WCPM's launch of a tender offer. Once this transaction closes, WCPM will be responsible for the operations of APPM, and International Paper will be a passive investor until such time that IP has sold its remaining share in APPM.

In conjunction with the announced agreement, a determination was made that the current book value of the APPM disposal group exceeded its estimated fair value of $119 million which was based on the agreed upon transaction price. As a result, a preliminary pre-tax charge of $152 million ($150 million after taxes) was recorded during the second quarter of 2019. This charge included $95 million related to the cumulative foreign currency translation loss and a $57 million loss related to the write down of the long-lived assets of APPM to their estimated fair value. This charge is included in the Net (gains) losses on sales and impairments of businesses in the accompanying consolidated statement of operations and is included in the results for the Printing Papers segment. A loss of $7 million (before and after taxes) has been allocated to the noncontrolling interest related to the impairment of the long-lived assets of APPM.

At June 30, 2019, all assets and liabilities related to APPM are classified as current assets held for sale and current liabilities held for sale in the accompanying consolidated balance sheet.

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

International Paper leases various real estate, including certain operating facilities, warehouses, office space and land. The Company also leases material handling equipment, vehicles, and certain other equipment. The Company's leases have remaining lease terms of one year to 97 years. 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.

Right of use (ROU) assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Effective January 1, 2019, operating lease 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.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments and Joint Ventures Disclosure [Text Block]

The Company accounts for the following investments in affiliated companies under the equity method of accounting.

Graphic Packaging International Partners, LLC

On January 1, 2018, the Company completed the transfer of its North American Consumer Packaging business, which included its North American Coated Paperboard and Foodservice businesses, to a subsidiary of Graphic Packaging International Partners, LLC (GPIP), a subsidiary of Graphic Packaging Holding Company, in exchange for a 20.5% ownership interest in GPIP. GPIP subsequently transferred the North American Consumer Packaging business to Graphic Packaging International, LLC (GPI), a wholly-owned subsidiary of GPIP that holds the assets of the combined business. The Company recorded equity earnings of $14 million and $15 million for the three months ended June 30, 2019 and 2018, respectively, and $27 million and $17 million for the six months ended June 30, 2019 and 2018, respectively. The Company received cash dividends from GPIP of $12 million and $6 million during the first six months of 2019 and 2018, respectively. The Company's investment in GPIP was $1.1 billion at both June 30, 2019 and December 31, 2018, which was $565 million and $562 million, respectively, more than the Company's proportionate share of the entity's underlying net assets. The difference primarily relates to the basis difference between the fair value of our investment and the underlying net assets, and is generally amortized in equity earnings over a period consistent with the underlying long-lived assets. The Company is party to various agreements with GPI under which it sells fiber and other products to GPI. Sales under these agreements were $74 million and $58 million for the three months ended June 30, 2019 and 2018, respectively, and $143 million and $118 million for the six months ended June 30, 2019 and 2018, respectively.

Summarized financial information for GPIP is presented in the following tables:

Ilim S.A.

The Company has a 50% equity interest in Ilim S.A. (Ilim), which has subsidiaries whose primary operations are in Russia. The Company recorded equity earnings (losses), net of taxes, of $67 million and $57 million for the three months ended June 30, 2019 and 2018, respectively, and $168 million and $149 million for the six months ended June 30, 2019 and 2018, respectively. The Company received cash dividends from the joint venture of $239 million and $116 million during the first six months of 2019 and 2018, respectively. At June 30, 2019 and December 31, 2018, the Company's investment in Ilim was $466 million and $478 million, respectively, which was $149 million and $145 million, respectively, more than the Company's proportionate share of the joint venture's underlying net assets. The differences primarily relate to currency translation adjustments and the basis difference between the fair value of our investment at acquisition and the underlying net assets. The Company is party to a joint marketing agreement with JSC Ilim Group, a subsidiary of Ilim, under which the Company purchases, markets and sells paper produced by JSC Ilim Group. Purchases under this agreement were $59 million and $56 million for the three months

ended June 30, 2019 and 2018, respectively, and $112 million and $109 million for the six months ended June 30, 2019 and 2018, respectively.

Income Tax Disclosure [Abstract]

Income Taxes [Note Text Block]

International Paper made income tax payments, net of refunds, of $97 million and $112 million for the six months ended June 30, 2019 and 2018, respectively.

The Company currently estimates, that as a result of ongoing discussions, pending tax settlements and expirations of statutes of limitations, the amount of unrecognized tax benefits could be reduced by approximately $35 million during the next 12 months.

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. The Company recorded a tax benefit of $6 million for each of the six months ended June 30, 2019 and 2018, respectively.

The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by International Paper do Brasil Ltda., a wholly-owned subsidiary of the Company. The Company received assessments for the tax years 2007-2015 totaling approximately $146 million in tax, and $377 million in interest and penalties as of June 30, 2019 (adjusted for variation in currency exchange rates). After a previous favorable ruling challenging the basis for these assessments, we received an unfavorable decision in October 2018 from the Brazilian Administrative Council of Tax Appeals. The Company has appealed this judgment to the Brazilian federal courts; however, this tax litigation matter may take many years to resolve. The Company believes that it has appropriately evaluated the transaction underlying these assessments, and has concluded based on Brazilian tax law, that its position would be sustained. The Company intends to vigorously defend its position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015.

COMMITMENTS AND CONTINGENCIES Footnote

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies [Note Text Block]

Environmental

International Paper 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 or 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 matters to be approximately $132 million ($142 million undiscounted) in the aggregate as of June 30, 2019. Other than as described below, completion of required remedial actions is not expected to have a material effect on our consolidated financial statements.

Cass Lake: One of the matters included above arises out of a closed wood-treating 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. The overall remediation reserve for the site is currently $48 million to address the selection of an alternative for the soil remediation component of the overall site remedy, which includes the ongoing groundwater remedy. In October 2011, the EPA released a public statement indicating that the final soil remedy decision would be delayed. In June 2019, the EPA issued a revised proposed plan concerning clean-up standards at a portion of the site, the estimated cost of which is included within the reserve referenced above. In October 2012, the Natural Resource Trustees for this site provided notice to International Paper and other PRPs of their intent to perform a Natural Resource Damage Assessment. It is premature to predict the outcome of the assessment or to estimate a loss or range of loss, if any, which may be incurred.

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 (the Allied Paper Mill) formerly owned by St. Regis Paper Company (St. Regis). The Company is a successor in interest to St. Regis.

• 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.

• In April 2016, the EPA issued a separate unilateral administrative order to the Company and certain other PRPs for a time-critical removal action (TCRA) of PCB-contaminated sediments from a different portion of the site. The Company responded to the unilateral administrative order and agreed along with two other parties to comply with the order subject to its sufficient cause defenses.

• In October 2016, the Company and another PRP received a special notice letter from the EPA inviting participation in the remedial design component of the landfill remedy for the Allied Paper Mill. The record of decision 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 remedial design.

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 with respect to this site. However, we do not believe that any material loss is probable.

The Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC in a contribution and cost recovery action for alleged pollution at the site. 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. The suit alleges that a mill, during the time it was allegedly owned and operated by St. Regis, discharged PCB contaminated solids and paper residuals resulting from paper de-inking and recycling. NCR Corporation and Weyerhaeuser Company are also named as defendants in the suit. In mid-2011, the suit was transferred from the District Court for the Eastern District of Wisconsin to the District Court for the Western District of Michigan.

The trial of the initial liability phase took place in February 2013. Weyerhaeuser conceded prior to trial that it was a liable party with respect to the site. In September 2013, an opinion and order was issued in the suit. The order concluded that the Company (as the successor to St. Regis) was not an “operator,” but was an “owner,” of the mill at issue during a portion of the relevant period and is therefore liable under CERCLA. The order also determined that NCR is a liable party as an "arranger for disposal" of PCBs in waste paper that was de-inked and recycled by mills along the Kalamazoo River. The order did not address the Company's responsibility, if any, for past or future costs. The parties’ responsibility, including that of the Company,

was the subject of a second trial, which was concluded in late 2015. 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. As to future remediation costs, we remain unable to estimate our maximum reasonably possible loss with respect to this site. However, we do not believe that any material loss is probable.

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 September 2016, the EPA issued a proposed remedial action plan (PRAP) for the site, which identified the preferred remedy as the removal of the contaminated material currently protected by an armored cap. In addition, the EPA selected a preferred remedy for the separate southern impoundment that requires offsite disposal. In January 2017, the PRPs submitted comments on the PRAP.

On October 11, 2017, the EPA issued a Record of Decision (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. While the EPA’s selected remedy was accompanied by a cost estimate of approximately $115 million, we do not believe that estimate provides a reasonable basis for accrual under GAAP because the estimate was based on a technological method for performing the work that we believe is not feasible. 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 over the subsequent 29 months. 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.

The Company has identified a number of concerns and uncertainties regarding the remedy described in the ROD and regarding the EPA’s estimates for the costs and time required to implement the selected remedy. The Company has determined, however, that even if the ROD cannot be implemented, a sheet pile "engineered barrier" can be constructed, which would enhance the existing remedy and could also be used should the ROD be determined to be feasible and implementable. In the third quarter of 2018, we increased our recorded liability accordingly to reflect the estimated cost of constructing this barrier. Because of ongoing questions regarding cost effectiveness, technical feasibility, timing and other technical data, however, it is uncertain how the ROD will be implemented. Consequently, while additional losses are probable as a result of the selected remedy, we are currently unable to determine any further adjustment to our immaterial recorded liability. It remains reasonably possible that additional losses could be material as the remedial design process with the EPA continues over the coming quarters.

International Paper and MIMC/WMI are also defending an additional lawsuit related to the site brought by approximately 600 individuals who allege property damage and personal injury. Because this case is still in the discovery phase, it is premature to predict the outcome or to estimate a loss or range of loss, if any, which may be incurred.

Antitrust

Containerboard: In January 2011, International Paper was named as a defendant in a lawsuit filed in state court in Cocke County, Tennessee alleging that International Paper violated Tennessee law by conspiring to limit the supply and fix the prices of containerboard from mid-2005 to the present. Plaintiffs in the state court action seek certification of a class of Tennessee indirect purchasers of containerboard products, damages and costs, including attorneys' fees. No class certification materials have been filed to date in the Tennessee action. The Company disputes the allegations made in the Tennessee lawsuit and is vigorously defending it. At this time, however, because the action is in a preliminary stage, we are unable to predict an outcome or estimate a range of reasonably possible loss.

Contract

Signature: In August 2014, a lawsuit captioned Signature Industrial Services LLC et al. v. International Paper Company was filed in state court in Texas. The Signature lawsuit arises out of approximately $1 million in disputed invoices related to the installation of new equipment at the Company's Orange, Texas mill. In addition to the invoices in dispute, Signature and its

president allege consequential damages arising from the Company's nonpayment of those invoices. The lawsuit was tried before a jury in Beaumont, Texas, in May 2017. On June 1, 2017, the jury returned a verdict awarding approximately $125 million in damages to the plaintiffs. The Court issued a judgment on December 14, 2017, awarding the plaintiffs a total of approximately $137 million in actual and consequential damages, fees, costs and pre-judgment interest, and awarding post-judgment interest. The Company has appealed this judgment. The Company has presented in its briefing numerous and strong bases for appeal, and we believe we will prevail on appeal. Because the appellate proceedings are ongoing, we are unable to estimate a range of reasonably possible loss, but we expect the amount of any loss to be immaterial.

General

The Company is involved in various other inquiries, administrative proceedings and litigation relating to environmental and safety matters, personal injury, labor and employment, contracts, sales of property, intellectual property, tax, antitrust and other matters, some of which allege substantial monetary damages. While any proceeding or litigation has the element of uncertainty, the Company believes that the outcome of any of these other lawsuits or claims that are pending or threatened or all of them combined (other than those that cannot be assessed due to their preliminary nature) will not have a material effect on its consolidated financial statements. See Note 14 for details regarding a tax matter.

Debt Disclosure [Abstract]

Debt [Note Text Block]

In June 2019, International Paper issued $200 million of 3.55% senior unsecured notes with a maturity date in 2029. The proceeds from this offering, together with a combination of available cash and other borrowings, were used for general corporate purposes, including repayment of outstanding commercial paper borrowings and other existing indebtedness.

In June 2018, the borrowing capacity of International Paper's commercial paper program was increased from $750 million to $1.0 billion. Under the terms of the 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.

Retirement Benefits [Abstract]

Retirement Plans [Note Text Block]

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 substantially all U.S. salaried employees and hourly employees (receiving salaried benefits) hired prior to July 1, 2004, and substantially all other U.S. hourly and union employees who work at a participating business unit regardless of hire date. These employees generally are eligible to participate in the Pension Plan upon attaining 21 years of age and completing one year of eligibility service. U.S. salaried employees and hourly employees (receiving salaried benefits) hired after June 30, 2004, are not eligible for the Pension Plan, but receive a company contribution to their Retirement Savings Account under the International Paper Company Salaried Savings Plan; however, salaried employees hired by Temple Inland prior to March 1, 2007 or Weyerhaeuser Company's Cellulose Fibers division prior to December 1, 2011 also participate in the Pension Plan.

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).

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 will instead receive a company contribution to their individual Retirement Savings Account.

Net periodic pension expense for our qualified and nonqualified U.S. defined benefit plans comprised the following: 

	Three Months Ended June 30,						Six Months Ended June 30,
In millions	2019			2018			2019			2018
Service cost	$	16		$	41		$	34		$	79

Amortization of prior service cost	4			4			8			8
Net periodic pension expense	$	21		$	73		$	47		$	115

The components of net periodic pension expense other than the Service cost component are included in Non-operating pension expense in the Consolidated Statement of Operations.

The Company’s funding policy for our pension plans is to contribute amounts sufficient to meet legal funding requirements, plus any additional amounts that the Company may determine to be appropriate considering the funded status of the plan, tax deductibility, the cash flows generated by the Company, and other factors. The Company made no voluntary cash contributions to the qualified pension plan in the first six months of 2019 or 2018. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $10 million for the six months ended June 30, 2019.

LEASES (Policies)

Leases [Abstract]

Lessee, Leases [Policy Text Block]

International Paper leases various real estate, including certain operating facilities, warehouses, office space and land. The Company also leases material handling equipment, vehicles, and certain other equipment. The Company's leases have remaining lease terms of one year to 97 years. 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.

Right of use (ROU) assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Effective January 1, 2019, operating lease 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.
