For management and financial reporting purposes, our businesses are separated into two segments: Industrial Packaging and Global Cellulose Fibers. A

description of these business segments can be found on pages 35 and 36 of Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

On September 18, 2023, we completed the previously announced sale of our 50% equity interest in Ilim S.A. ("Ilim"), which was a joint venture that operated a pulp and paper business in Russia and has subsidiaries including Ilim Group. We also completed the sale of all of our Ilim Group shares (constituting a 2.39% stake) and divested other non-material residual interests associated with Ilim. Following the completed sales, we no longer have an interest in Ilim or any of its subsidiaries, and no longer have any investments in Russia. As a result, all current and historical results of the Ilim investment reportable segment are presented as Discontinued Operations, net of taxes. See discussion in Note 11 - Equity Method Investments on pages 69 and 70 of Item 8. Financial Statements and Supplementary Data.

Following our public announcement on October 18, 2023, the Company permanently closed its containerboard mill in Orange, Texas on December 4, 2023 and permanently ceased production on two of its pulp machines at its Riegelwood, North Carolina and Pensacola, Florida mills on December 11, 2023. The mill closure resulted in pre-tax non-cash asset write-off and accelerated depreciation charges of approximately $347 million and pre-tax cash severance and other shutdown charges of approximately $81 million. The machine shutdowns resulted in pre-tax non-cash asset write-off and accelerated depreciation charges of approximately $75 million and pre-tax cash severance and other shutdown charges of approximately $37 million. The Company recorded these charges in the fourth quarter of 2023.

From 2019 through 2023, International Paper’s capital spending approximated $4.6 billion, excluding mergers and acquisitions. These expenditures reflect our continuing efforts to use our capital strategically to improve product quality and environmental performance, as well as lower costs, maintain reliability of operations and deploy strategic capital for capacity expansion. Capital spending in 2023 was approximately $1.1 billion and is expected to be approximately $800 million to $1.0 billion in 2024.
