Depreciation expense was $0.2 million for each of the three months ended June 30, 2017 and 2016. Depreciation expense was $0.3 million for each of the six months ended June 30, 2017 and 2016.

As of December 31, 2016, we recorded an impairment charge related to certain equipment that we were no longer using and adjusted the carrying value of this equipment to its estimated net realizable value of $0.4 million. During the first quarter of 2017, we began to seek out a buyer for this equipment, and as such, we reclassified the amount and continue to classify the amount on our Condensed Consolidated Balance Sheets under the caption, “Assets held for sale.”
