At June 30, 2018 and December 31, 2017, property, plant and equipment, net, with a net carrying value of $86.0 million and $82.8 million, respectively, was located outside the United States.

During the six month period ended June 30, 2018, the increase in Property, Plant and Equipment is due primarily to spending on equipment for compliance with the Drug Supply Chain Security Act ("DSCSA") requirements and expansion initiatives at our Decatur and Somerset manufacturing plants.

At June 30, 2018, the Company had $116.2 million of assets under construction which consisted primarily of investment in building expansions, equipment, and compliance with DSCSA. Depreciation will begin on these assets once they are placed into service. These projects are expected to be completed in 2018 and 2019. The Company assesses its long-lived assets, consisting primarily of property and equipment, for impairment when material events and changes in circumstances indicate that the carrying value may not be recoverable. There were no impairment losses recorded in 2018 or 2017.

The Company recorded depreciation expense of $7.0 million and $5.8 million during the three month periods ended June 30, 2018 and 2017, respectively
