Outsourcing Services Agreement [Abstract]
Outsourcing services agreement	Outsourcing Services Agreement Under an Outsourcing Services Agreement, a wholly-owned subsidiary of Packaging Corporation of America (PCA) provides a number of corporate staff services to us. These services include, but are not limited to, information technology, accounting, and human resource transactional services. On November 17, 2014, we entered into the Fifth Amendment to Outsourcing Services Agreement (the “Amendment”) with PCA, which amends the Outsourcing Services Agreement, dated February 22, 2008 (the “Agreement”), to, among other things, provide expiration dates for the termination of substantially all administrative services provided by PCA to us pursuant to the Agreement. For those services scheduled to be terminated, the expiration dates are planned to occur between March 2015 and December 2015. Services for which the Amendment does not provide expiration dates will generally continue under the same terms and conditions of the Agreement. These administration services will transition from PCA to us upon expiration. During and after transition, our information technology systems will remain in place with many of the administrative services performed by newly hired employees, many of whom we expect to transition from PCA to Boise Cascade employment. Total expenses incurred under the Outsourcing Services Agreement were $15.1 million, $15.5 million, and $15.0 million, respectively, for the years ended December 31, 2014, 2013, and 2012. The majority of these expenses are recorded in "General and administrative expenses" in our Consolidated Statements of Operations.
