Acquisitions [Note Text Block]	ACQUISITIONS Weyerhaeuser Pulp Business On May 1, 2016, the Company entered into a definitive agreement to purchase the pulp business of Weyerhaeuser Company for $2.2 billion in cash, subject to certain adjustments, including a reduction for the amount of debt being assumed, which was approximately $88 million as of June 30, 2016. Because the transaction is a purchase of assets, International Paper expects to realize a tax benefit with an estimated net present value of approximately $300 million. Under the terms of the agreement, International Paper will acquire four fluff pulp mills, one Northern bleached softwood kraft mill and two converting facilities of modified fiber, located in the United States, Canada and Poland. The acquisition is expected to close in the fourth quarter of 2016, subject to certain closing conditions, primarily the receipt of regulatory approvals. On August 4, 2016, the Company learned that the U.S. Department of Justice had completed its investigation without taking any action, but regulatory approval is still needed in other jurisdictions. Holmen Paper Newsprint Mill On June 30, 2016, the Company completed the previously announced acquisition of Holmen Paper's newsprint mill in Madrid, Spain. Under the terms of the agreement, International Paper purchased the Madrid newsprint mill, as well as, associated recycling operations and a 50% ownership interest in a cogeneration facility. The Company intends to convert the mill during the second half of 2017 to produce recycled containerboard with an expected capacity of 380,000 metric tonnes. Once completed, the converted mill will support the Company's corrugated packaging business in EMEA. The Company's aggregated purchase price for the mill, recycling operations and 50% ownership of the cogeneration facility was €54 million (approximately $61 million using June 30, 2016 exchange rate). Approximately 85% of the purchase price was allocated to property, plant and equipment and the remaining 15% to equity method investments.
