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 andexceeds its fair value.There were no asset impairments of property, plant, and equipment during the three months ended March 31, 2017 and 2016.

Depreciation expense for the three-month periods ended March 31, 2017 and 2016 was $3,282 and $3,727, respectively.
