CHICAGO, Dec. 8 -- R.R. Donnelley & Sons Company today announced plans to withdraw the listing of its common stock from the former Pacific Stock Exchange, now Arca, Inc. RR Donnelley's common stock will continue to be listed on the New York Stock Exchange, the Chicago Stock Exchange and the Toronto Stock Exchange. As a result of the recent merger of the Group with Archipelago Holdings, the parent company of Arca, Inc., RR Donnelley is subject to duplicative administrative requirements in connection with its dual listings. Voluntarily withdrawing its listing from Arca, Inc. eliminates these added administrative requirements. Arca, Inc. will continue trading RR Donnelley's securities on an unlisted trading privilege basis.
