We review our property, plant, and equipment for recoverability whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. We recognize an impairment loss if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. There were no asset impairments of property, plant, and equipment during the nine months ended September 30, 2017.

Depreciation expense for the three-month periods ended September 30, 2017 and 2016 was $3,178 and $3,295, respectively. For the nine-month periods ended September 30, 2017 and 2016, depreciation expense was $9,705 and $10,620, respectively.
