Goderich Tornado [Abstract]
Goderich Tornado	Goderich Tornado: In August 2011, a tornado struck the Company’s salt mine and its salt mechanical evaporation plant, both located in Goderich, Ontario, Canada. There was no damage to the underground operations at the mine. However, some of the mine’s surface structures and the evaporation plant incurred significant damage which temporarily ceased production at both facilities. Both facilities resumed normal production and shipping activities in 2012. The Company recorded impairment of its property, plant and equipment and clean-up and restoration costs during 2011 through 2013 related to the impacted areas at both of the Goderich facilities. There were no material expenses or charges related to the tornado in 2014. In the third quarter of 2014, the Company resolved all contingencies and settled its insurance claim. The settlement included a substantial amount related to business interruption losses. Cumulatively, the Company received $114.9 million in cash, including approximately $28.6 million received in 2014 which was originally recorded as deferred revenue in the Company’s consolidated balance sheets. The insurance proceeds included approximately $26.9 million related to clean-up and restoration costs and asset impairment charges and approximately $83.3 million of proceeds for the replacement of property, plant and equipment and business interruption losses. In connection with the settlement, the Company released its deferred revenue balance of $83.3 million and recorded a gain of $82.3 million as a reduction to product cost and approximately $1.0 million as a reduction to selling, general and administrative expenses in its consolidated statements of operations for the third quarter of 2014. The difference between the cash received and the amounts recorded above relates to the foreign exchange impact from translating amounts from Canadian dollars to U.S. dollars.
