Property and Business Interruption Insurance Claims and Recoveries	20. Property and Business Interruption Insurance Claims and Recoveries On November 13, 2012, a pipe ruptured within our Cherokee Facility causing damage primarily to the heat exchanger portion of its ammonia plant. No serious injuries or environmental effect resulted from the pipe rupture. As a result of the damage, the Cherokee Facility could only produce, on a limited basis, nitric acid and AN solution from purchased ammonia until the repairs were completed. Our insurance policy provided, for the policy period covering this claim, for repair or replacement cost coverage relating to property damage with a $2.5 million deductible and provided for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period. As a result of this event, a notice of insurance claims for property damage and business interruption was filed with the insurance carriers. In 2013, we received business interruption insurance recovery of $15 million and was applied against recoverable costs (primarily relating to additional expenses associated with purchased product sold or used in products sold to our customers while our facility was being repaired) totaling $13.6 million as a reduction to cost of sales. The insurance recovery in excess of recoverable costs of $1.4 million was deferred (included in deferred gain on insurance recoveries at December 31, 2013) since this amount relates to lost profits, which is considered a gain contingency. In January 2014, we settled the claim with our insurance carriers for the aggregate amount of approximately $43.5 million (of which approximately $36.5 million relates to the business interruption claim), comprised of $15 million previously paid to us in 2013 and $28.5 million paid to us in 2014. The $43.5 million settlement amount is net of our $2.5 million property insurance deductible. As a result, an insurance recovery of approximately $28 million was recognized as a reduction to cost of sales associated with this settlement in 2014.
