MONTREAL, Dec. 5 - Domtar Inc. announced today that it has reached an agreement in principle to sell its 50% interest in Norampac Inc. to Cascades Inc. for a cash consideration of $560 million. Proceeds of the transaction will mainly be used to reduce financing requirements for the recently announced transaction with Weyerhaeuser. "The combination of our packaging assets with Cascades' has been a success for both partners. While we considered our participation in Norampac as a good investment and always supported its growth throughout the years, this interest in Norampac had long been identified as non core to Domtar. The transaction announced today represents another step Domtar is taking to deliver on its strategic plan aimed at becoming a preferred supplier of fine paper products in North America and at monetizing non core assets in an effort to further strengthen its overall financial position," said Raymond Royer, President and Chief Executive Officer. The transaction is subject to the negotiation of definitive agreements as well as the necessary approvals, including that of the regulatory authorities. The transaction is expected to close before the end of the year.
