Costs Associated with Exit or Disposal Activities

Closure of Brainerd, Minnesota Mill

On February 21, 2013, Wausau Paper Corp. announced its intent to close the Company's Brainerd, Minnesota, technical specialty paper mill, with manufacturing operations to end early in the second quarter of 2013.

Pre-tax closure charges are estimated to be approximately $47 million, with non-cash charges, primarily related to the write-down of long-lived assets, accounting for approximately $44 million of this total. The estimated cash expenditures of $3 million include one-time termination benefits and other related closure costs. After considering income taxes and an anticipated reduction in working capital, the Company expects the impact of the closure to be cash neutral. Pre-tax closure charges of approximately $36 million are expected in the first quarter of 2013, with the remaining charges of approximately $11 million occurring during the balance of 2013.
