Lower of Cost or Market Inventory Adjustments	Lower of Cost or Market and Other Inventory Adjustments During the three-month period ended March 31, 2015, the Company reviewed the carrying values of all inventories and concluded that certain inventories in China had been impacted by changes in market conditions. Current market prices had fallen below carrying costs for certain inventories. Consequently, the Company recognized a $3,887 loss in cost of sales, to adjust finished goods and raw materials carrying values to the lower market prices on inventories inside China. 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. The Company again reviewed the carrying values of all inventories as of June 30, 2015 and concluded that no further adjustments were warranted as of that time. In addition, during the three month period ended March 31, 2015, the Company recognized a $485 loss in cost of sales as a result of other inventory adjustments unrelated to lower of cost or market issues.
Production Levels Below Normal Capacity	Production Levels Below Normal Capacity As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal capacity was triggered and resulted in certain production costs being 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. The Company expensed $19,629 in production costs during the six month period ended June 30, 2015. There were no such costs in the prior year period.
Long-lived assets impairment considerations	Long-lived assets impairment considerations At the time the manufacturing facility in McIntyre, Georgia was mothballed, the Company conducted an interim impairment analysis of the related long-lived assets. Pursuant to that analysis, the Company determined that the projected gross cash flows attributable to the facility substantially exceed the carrying value of the assets; therefore, the Company concluded that there was no impairment and further that impairment would not be reasonably possible in the near term. At the time the manufacturing facility was mothballed in Luoyang, China, the Company did not conduct an interim impairment analysis because an impairment charge was recorded in 2014 that reduced the value of the related long-lived assets to net salvage value. The Company does not necessarily assess temporarily idled assets for impairment unless events or circumstances indicate their carrying amounts might not be recoverable. The Company tests goodwill on an annual basis as of December 31 of each year. The 2014 impairment analysis considered industry conditions that were developing into early 2015 as a result of the severe decline in oil prices. The Company concluded that there was no impairment to goodwill as of December 31, 2014. The Company will also test goodwill for impairment in interim periods in which events occur or circumstances arise that could indicate that the carrying amounts of goodwill may not be recoverable. During 2015, no new events or circumstances were noted that would suggest the need to retest goodwill for impairment.

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.
