Subsequent Events [Abstract]
Subsequent Events	Subsequent Events: Restructuring In connection with the announced realignment of our operating segments, in October 2013, we initiated a voluntary separation program available to salaried employees in the U.S. At this time, we cannot reasonably estimate the total restructuring charge that will be incurred in the fourth quarter of 2013, as not all of our restructuring initiatives have been finalized, but as of this filing we expect the charge to be no more than $20 million. Acquisition On October 1, 2013, we acquired Cambridge Chemical Company, Ltd. for approximately $3.6 million.
