Potlatch Corporation to Withdraw Pacific Exchange Listing, Retains New York Stock Exchange Listing.

SPOKANE, Wash. -- Potlatch Corporation (NYSE:PCH), a real estate investment trust (REIT), today announced plans to withdraw the listing of its common stock from NYSE Arca, Inc., formerly the Pacific Exchange. Potlatch's common stock will continue to be listed on the New York Stock Exchange.

Potlatch has decided to withdraw its listing from NYSE Arca, Inc. to streamline operations and eliminate duplicative administrative requirements inherent with dual listings as a result of the NYSE Group's recent merger with Archipelago Holdings, the parent company of NYSE Arca. This withdrawal is expected to be effective within the next month.

Potlatch does not believe that withdrawing its listing from NYSE Arca, Inc. will have any impact on the liquidity of its stock. NYSE Arca will continue trading Potlatch stock on an unlisted trading privilege basis.

Potlatch is a REIT with 1.5 million acres of forestland in Arkansas, Idaho, Minnesota and Oregon. Through a taxable REIT subsidiary, the company also operates 13 manufacturing facilities that produce lumber and panel products and bleached pulp products, including paperboard and tissue products.
