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 six months ended June 30, 2017.

Depreciation expense for the three-month periods ended June 30, 2017 and 2016 was $3,245 and $3,598, respectively. For the six-month periods ended June 30, 2017 and 2016, depreciation expense was $6,527 and $7,325, respectively.
