In a Seattle Times Jon Talton column today, this list of Puget Sound area corporate headquarters that have gone away - somewhere - over the last decade: "It's a painful list: Boeing, Washington Mutual, Safeco, Immunex, Puget Sound Energy during the last decade."
The point of the column was to add another: Todd Pacific Shipyards, where 800 people in the area have worked.
At least this one isn't going far away: The new owner, probably (the deal evidently isn't final), is Vigor Industrial of Portland.
Talton adds this significant point: "Publicly traded Todd is essentially in play, and other bidders might emerge. Vigor is privately held and less vulnerable to Wall Street's destructive whims (take note, Microsoft and others)."
