Disclosure Nature Of Operations And Basis Of Presentation Additional Information [Abstract]
Nature of Operations and Basis of Presentation	NOTE 1 Nature of Operations and Basis of Presentation Clearwater Paper Corporation is a leading North American producer of private label tissue and paperboard products. We manufacture quality consumer tissue, away-from-home tissue, parent rolls (non-converted tissue product), machine-glazed tissue, bleached paperboard and pulp at 14 manufacturing locations in the U.S. and Canada. Our private label consumer tissue products - facial and bath tissue, paper towels and napkins - are used primarily at-home and are principally sold to major retailers and wholesale distributors, which include grocery, drug, mass-merchant and discount stores. Our paperboard is sold primarily in the high-end segment of the packaging industry, which demands high-quality construction and print surfaces for graphics. Our products are made primarily from wood fiber pulp. Unless the context otherwise requires or unless otherwise indicated, references in this report to “Clearwater Paper Corporation,” “we,” “our,” “the company” and “us” refer to Clearwater Paper Corporation and its subsidiaries. On November 28, 2011, we sold our Lewiston, Idaho, sawmill to Idaho Forest Group of Coeur d’Alene, Idaho. The transaction included the sale of our sawmill, planer mill, dry kilns and related assets along with log and finished goods inventories and timber under contract, in the aggregate amount of approximately $30 million. This sawmill was our only wood products facility. On December 28, 2012, we acquired the assets of a wood chipping facility located in Clarkston, Washington, near our Lewiston, Idaho facility, in an effort to bolster our wood fiber position and obtain short-term and long-term cost savings. The total consideration associated with the acquisition was approximately $11 million, which includes contingent consideration over an 18 month period of up to $1.5 million in cash to be paid by the company, based on certain performance and indemnity guarantees. At December 31, 2013, this $1.5 million is considered restricted cash. We allocated the purchase price to the tangible and amortizable intangible assets acquired based on their estimated fair values at the date of acquisition, resulting in the recognition of approximately $6 million in equipment, $4 million in intangible assets for customer relationships and a $1 million intangible asset for a non-compete agreement with the former owners. No goodwill was recorded. On March 6, 2013, we announced the planned permanent closure of our Thomaston, Georgia converting and distribution facility. The shutdown occurred gradually as converting lines were relocated and installed at our other facilities, with all operations at Thomaston having ceased as of the end of 2013. We incurred $6.0 million of costs associated with the closure in 2013. On February 17, 2004, in an event subsequent to the close of our 2013 fiscal year, we announced the permanent and immediate closure of our Long Island, New York, tissue converting and distribution facility.
