Accounting Policies [Abstract]

Lower of Cost or Market Adjustments

Lower of Cost or Market Adjustments

As of September 30, 2016, the Company reviewed the carrying values of all inventories and concluded that certain sand inventories were impacted by changes in market conditions.  Current market prices had fallen below carrying costs for certain of these sand inventories.  Consequently, during the three-month period ended September 30, 2016, the Company recognized a $115 loss in cost of sales to adjust the carrying value to the lower market prices on certain sand inventories.  There was no such adjustment during the same period in 2015.  During the nine-month period ended September 30, 2016 and 2015, the Company recognized a $115 and $4,372 loss, respectively, in cost of sales, primarily to adjust the carrying values to the lower market prices.  The adjustments were based on current market prices for these or similar products, as determined by actual sales, bids, and/or quotes from third parties.

Manufacturing Production Levels Below Normal Capacity

Manufacturing Production Levels Below Normal Capacity

As a result of the Company substantially reducing manufacturing production levels, including by idling certain facilities, certain production costs have been expensed instead of being capitalized into inventory.  The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels.  For the three months ended September 30, 2016 and 2015, the Company expensed $12,845 and $5,528, respectively, in production costs.  For the nine months ended September 30, 2016 and 2015, the Company expensed $36,067 and $25,157, respectively, in production costs.

Long-lived and other noncurrent assets impairment considerations

Long-lived and other noncurrent assets impairment considerations

As noted, the Company has temporarily idled production at various manufacturing facilities throughout 2016.  The Company does not necessarily assess temporarily idled assets for impairment unless events or circumstances indicate that the carrying amounts of those assets may not be recoverable.  Short-term stoppages of production for less than one year do not generally significantly impact the long-term expected cash flows of the idled facility.  As of March 31, 2016, as a result of changes in the planned usage of certain long-term bauxite raw materials, the Company evaluated the carrying value of those bauxite raw materials.  Based upon this evaluation, during the three months ended March 31, 2016, the Company recognized an impairment charge of $1,065 on these bauxite raw material inventories.  As of September 30, 2016, the Company concluded that there were no events or circumstances that would indicate that carrying amounts of other long-lived and other noncurrent assets might be further impaired.  However, the Company continues to monitor market conditions closely.  Further deterioration of market conditions could result in impairment charges being taken on these and/or other long-lived and other noncurrent assets, including the Company’s manufacturing plants, goodwill and intangible assets.  The Company will evaluate long-lived and other noncurrent assets for impairment at such time that events or circumstances indicate that carrying amounts might be impaired.
