Related Party Transactions [Abstract] |
Transactions With Related Parties | Transactions With Related Parties Louisiana Timber Procurement Company, L.L.C. (LTP) is an unconsolidated variable-interest entity that is 50% owned by us and 50% owned by Packaging Corporation of America (PCA). LTP procures sawtimber, pulpwood, residual chips, and other residual wood fiber to meet the log and fiber requirements of us and PCA in Louisiana. We are not the primary beneficiary of LTP, as we do not have power to direct the activities that most significantly affect the economic performance of LTP. Accordingly, we do not consolidate LTP's results in our financial statements. Sales Related-party sales to LTP from our Wood Products segment in our Consolidated Statements of Operations were $16.6 million, $17.4 million, and $20.7 million, respectively, during the years ended December 31, 2017, 2016, and 2015. These sales are recorded in "Sales" in our Consolidated Statements of Operations. Costs and Expenses Related-party wood fiber purchases from LTP were $86.4 million, $87.2 million, and $88.8 million, respectively, during the years ended December 31, 2017, 2016, and 2015. These costs are recorded in "Materials, labor, and other operating expenses (excluding depreciation)" in our Consolidated Statements of Operations.
