Goderich Tornado [Abstract]  
Goderich Tornado Costs Incurred and Insurance Recoveries
The Company maintains comprehensive property and casualty insurance, including business interruption, which is expected to provide substantial coverage for the losses that have and will occur at these facilities and to our business related to the tornado. The Company made an estimate of the impairment of its property, plant and equipment pertaining to the impacted areas at both of the Goderich facilities.  The Company may need to record additional impairment charges as more information becomes available.  In addition, the Company incurred clean-up costs related to the storm. The Company expects to be fully reimbursed by its insurers for the replacement and repair costs for its property, plant and equipment and associated clean-up costs incurred, net of the Company's deductible. The impairment and clean-up and restoration costs incurred and insurance recoveries recognized in the consolidated statements of operations for the three and nine months ended September 30, 2012 and 2011 are as follows (in millions):
