Section 8 – Other Events

Item 8.01.

Other Events

Sale of Roll Wrap Business

Wausau Paper Corp. has sold the roll wrap portion of its specialty products business to Cascades Sonoco, Inc.  The Company will continue to manufacture roll wrap and related products for the buyer during a post-closing transition period which expires on July 2, 2008.  The Company has retained the real property at its Columbus, WI and Jackson, MS production facilities and intends to sell the real property following completion of the transition period.  After sale of the facilities, the impact of the transaction on earnings is expected to be neutral, while the ongoing effect of the transaction is expected to be slightly accretive to earnings as compared to recent historical operating results.  The divested roll wrap business represents approximately 3% of the Company’s annual consolidated net sales.

Forward Looking Statements

Statements concerning the effect of the sale of the Company’s specialty products roll wrap business constitute forward-looking information and are made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.  While the Company believes that these forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance, and all such statements involve risk and uncertainties that could cause actual results to differ materially from those contemplated and expressed in this report.  The assumptions, risks, and uncertainties relating to the forward-looking statements in this report include the risks and assumptions described under “Information Concerning Forward-Looking Statements” in Item 7 and in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2006, and from time to time, in the Company’s other filings with the Securities and Exchange Commission.  The Company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.
