Nature of Operations and Basis of Presentation

1. Nature of Operations and Basis of Presentation

Packaging Corporation of America (“we,” “us,” “our,” “PCA,” or the “Company”) was incorporated on January 25, 1999. In April 1999, PCA acquired the containerboard and corrugated packaging products business of Pactiv Corporation (Pactiv), formerly known as Tenneco Packaging, Inc., a wholly owned subsidiary of Tenneco Inc. We are a large, diverse manufacturer of both packaging and paper products. We are headquartered in Lake Forest, Illinois and we operate primarily in the United States. We have approximately 15,500 employees.

We report our business in three reportable segments: Packaging, Paper, and Corporate and Other. Our Packaging segment produces a wide variety of containerboard and corrugated packaging products. The Paper segment manufactures and sells a range of communication-based papers. During the second quarter of 2018, the Company discontinued the production of uncoated free sheet and coated one-side white paper grades at the Wallula, Washington mill and converted the No. 3 machine at the mill from production of white papers to production of virgin kraft linerboard. Before May 2018, operating results for the Wallula mill were included in the Paper segment. After May 2018, operating results for the Wallula mill are primarily included in the Packaging segment. Corporate and other includes support staff services and related assets and liabilities, transportation assets, and activity related to other ancillary support operations. For more information about our segments, see Note 20, Segment Information.

In these consolidated financial statements, certain amounts in prior periods’ consolidated financial statements have been reclassified to conform with the current period presentation.

The consolidated financial statements include the accounts of PCA and its majority-owned subsidiaries after elimination of intercompany balances and transactions.
