INTERNATIONAL PAPER CO NEW

The preparation of financial statements in conformity with U.S. GAAP 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 subjective judgments about matters that are inherently uncertain.

Accounting policies whose application has had or is reasonably likely to have a material impact on the reported results of operations and financial position of International Paper, and that can require a significant level of estimation or uncertainty by management that affect their application, include the accounting for contingencies, impairment or disposal of long-lived assets and goodwill, pensions and income taxes. Management has discussed the selection of critical accounting policies and the effect of significant estimates with the Audit and Finance Committee of the Company’s Board of Directors and with its independent registered public accounting firm.

CONTINGENT LIABILITIES

Accruals for contingent liabilities, including personal injury, product liability, environmental, asbestos and other legal matters, are recorded when it is probable that a liability has been incurred or an asset impaired and the amount of the loss can be reasonably estimated. Liabilities accrued for legal matters require judgments regarding projected outcomes and range of loss based on historical litigation and settlement experience and recommendations of legal counsel and, if applicable, other experts. Liabilities for environmental matters require evaluations of relevant environmental regulations and estimates of future remediation alternatives and costs. The Company estimated the probable liability associated with environmental matters to be approximately $279 million and $251 million in the aggregate as of December 31, 2024 and 2023, respectively. Liabilities for asbestos-related matters require reviews of recent and historical claims data. The Company's total recorded liability with respect to pending and future asbestos-related claims was $100 million and $97 million, net of estimated insurance recoveries, as of December 31, 2024 and 2023, respectively. The Company utilizes its in-house legal counsel and environmental experts to develop estimates of its legal, environmental and asbestos obligations, supplemented as needed by third-party specialists to analyze its most complex contingent liabilities.

IMPAIRMENT OF LONG-LIVED ASSETS AND GOODWILL

Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that indicate that the carrying value of the assets may not be recoverable. A recoverability test is performed by comparing the undiscounted cash flows to carrying value of the assets. If the carrying amount is less than the undiscounted cash flows, the fair value of the assets is compared to the carrying value to determine if they are impaired. An impairment of a long-lived asset exists when the asset’s carrying amount exceeds its fair value.

We perform an annual goodwill impairment as of October 1. Additionally, interim assessments of possible impairments of goodwill are also made when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable through future operations. A goodwill impairment exists when the carrying amount of goodwill exceeds its fair value.

The amount and timing of goodwill and long-lived asset impairment charges based on these assessments requires the estimation of future cash flows or the fair market value of the related assets based on management’s best estimates of certain key factors, including future selling prices and volumes, operating, raw material, energy and freight costs, various other projected operating economic factors and other intended uses of the assets.

ASU 2011-08, "Intangibles - Goodwill and Other," allows entities testing goodwill for impairment the option of performing a qualitative assessment before performing the quantitative goodwill impairment test. If a qualitative assessment is performed, an entity is not required to perform the quantitative goodwill impairment test unless the entity determines that, based on that qualitative assessment, it is more likely than not that its fair value is less than its carrying value.

The North America Industrial Packaging reporting unit is the Company’s only reporting unit with goodwill. As of October 1, 2024, we performed our annual goodwill impairment test for this reporting unit through a quantitative goodwill impairment test. For the 2024 quantitative assessment, the estimated fair value of the reporting unit was calculated using a weighted approach based on discounted future cash flows, market multiples and transaction multiples. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions including forecasts of revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant assumptions related to revenue multiples and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples. The results of our quantitative goodwill impairment test indicated that the carrying amount did not exceed the estimated fair value of the North America Industrial Packaging reporting unit.

PENSION BENEFIT OBLIGATIONS

The calculation of the pension benefit obligation and corresponding expense amounts are determined annually, with involvement of International Paper’s consulting actuary, and are dependent upon various assumptions including the expected long-term rate of return on plan assets, discount rates, projected future compensation increases and mortality rates.

The calculations of pension benefit obligations and expense require decisions about a number of key assumptions that can significantly affect liability and expense amounts, including the expected long-term rate of return on plan assets and the discount rate used to calculate plan liabilities.

Benefit obligations and fair values of plan assets as of December 31, 2024, for International Paper’s pension plan were as follows:

The table below shows the discount rate used by International Paper to calculate U.S. pension obligations for the years shown:

International Paper determines the actuarial assumptions to calculate liability information as of December 31 each year or more frequently if required and pension expense for the following year. International Paper consults with our third-party actuary in determining these actuarial assumptions. The expected long-term rate of return on plan assets is based on projected rates of return for current asset classes in the plan’s investment portfolio. The discount rate assumption was determined based on a hypothetical settlement portfolio selected from a universe of high-quality corporate bonds.

The expected long-term rate of return on U.S. pension plan assets used to determine net periodic cost for the year ended December 31, 2024 was 7.00%.

Increasing the expected long-term rate of return on U.S. plan assets by an additional 0.25% would decrease 2025 pension expense by approximately $20 million, while a (decrease) increase of 0.25% in the discount rate would (increase) decrease pension expense by approximately $14 million.

Actual rates of return earned on U.S. pension plan assets for each of the last 10 years were:

ASC 715, “Compensation – Retirement Benefits,” provides for delayed recognition of actuarial gains and losses, including amounts arising from changes in the estimated projected plan benefit obligation due to changes in the assumed discount rate, differences between the actual and expected return on plan assets, and other assumption changes. These net gains and losses are recognized in pension expense prospectively over a period that approximates the average remaining service period of active employees expected to receive benefits under the plans to the extent that they are not offset by gains and losses in subsequent years.

Net periodic pension plan expenses, calculated for all of International Paper’s plans, were as follows:

The decrease in 2024 pension expense primarily reflects higher asset returns, lower interest cost due to a lower discount rate, and lower actuarial loss.

Assuming that discount rates, expected long-term returns on plan assets and rates of future compensation increases remain the same as of December 31, 2024, projected future net periodic pension plan expense (income) would be as follows:

The Company estimates that it will record net pension expense of approximately $36 million for its U.S. defined benefit plans in 2025, compared to expense of $1 million in 2024.

The market value of plan assets for International Paper’s U.S. qualified pension plan at December 31, 2024 totaled approximately $8.2 billion, consisting of approximately 62% hedging assets and 38% return seeking assets. The Company’s funding policy for its qualified pension plan 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 continually reassesses the amount and timing of any discretionary contributions and could elect to make voluntary contributions in the future. There were no required contributions to the U.S. qualified plan in 2024. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $23 million for the year ended December 31, 2024.

International Paper records its global tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in its income tax returns. Where treatment of a position is uncertain, liabilities are recorded based upon the Company’s evaluation of the “more likely than not” outcome considering technical merits of the position based on specific tax regulations and facts of each matter. Changes to recorded liabilities are only made when an identifiable event occurs that changes the likely outcome, such as settlement with the relevant tax authority, the expiration of statutes of limitation for the subject tax year, change in tax laws, or recent court cases that are relevant to the matter. Accrued interest related to these uncertain tax positions is recorded in our consolidated statement of operations in Interest expense, net. The Company's uncertain tax positions were $204 million and $173 million at December 31, 2024 and 2023, respectively.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in assessing the need for and magnitude of appropriate valuation allowances against deferred tax assets. This assessment is completed by tax jurisdiction and relies on both positive and negative evidence available, with significant weight placed on recent financial results. Cumulative reported pre-tax income is considered objectively verifiable positive evidence of our ability to generate positive pre-tax income in the future. In accordance with GAAP, when there is a recent history of pre-tax losses, there is little or no weight placed on forecasts for purposes of assessing the recoverability of our deferred tax assets. When necessary, we use systematic and logical methods to estimate when deferred tax liabilities will reverse and generate taxable income and when deferred tax assets will reverse and generate tax deductions. Assumptions, judgment, and the use of estimates are required when scheduling the reversal of deferred tax assets and liabilities, and the exercise is inherently complex and subjective. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. The Company's valuation allowance was $1.2 billion and $848 million at December 31, 2024 and 2023, respectively.

While International Paper believes that these judgments and estimates are appropriate and reasonable under the circumstances, actual resolution of these matters may differ from recorded estimated amounts.
