Subsequent Events [Abstract]
Subsequent Events	On April 16, 2024, the Company issued an announcement, pursuant to Rule 2.7 of the United Kingdom City Code on Takeovers and Mergers, disclosing the terms of a recommended offer by the Company to acquire the entire issued and to be issued share capital of DS Smith Plc, a public limited company incorporated in England and Wales (“DS Smith”), in an all-stock transaction (the “Business Combination”). Under the terms of the Business Combination, each DS Smith share will be valued at 415 pence per share based on the Company’s closing share price of $40.85 and GBP/USD exchange rate of 1.2645 on March 25, 2024, being the close of business on the last day prior to the announcement by DS Smith of a previously disclosed possible offer by the Company. This will result in IP issuing 0.1285 shares for each DS Smith share, resulting in pro forma ownership of 66.3% for IP shareholders and 33.7% for DS Smith shareholders, with an implied enterprise value of approximately $9.9 billion. Costs related to the transaction were $5 million for the three months ended March 31, 2024. In connection with the Business Combination, the Company also intends to seek a secondary listing of International Paper common stock on the London Stock Exchange. Following completion of the Business Combination, Memphis, Tennessee will be the headquarters of the combined company, with plans to establish a Europe, Middle East and Africa (EMEA) headquarters at DS Smith’s existing London headquarters. Upon the closing of the Business Combination, it is intended that the Company’s board of directors will form the board of directors of the combined company, and that up to two directors of DS Smith will be invited to join the board of directors of the combined company. Mr. Andrew K. Silvernail will be the Chief Executive Officer of the combined company. The transaction is expected to close during the fourth quarter of 2024, subject to the approval of IP shareholders and DS Smith shareholders, as well as customary closing conditions, including regulatory clearances in Europe and the U.S.
