Depreciation and amortization expense related to property, plant and equipment, net, was $3.4 million and $2.5 million for the three months ended September 30, 2020 and 2019, respectively, and $9.1 million and $7.5 million for the nine months ended September 30, 2020 and 2019, respectively.

The Company tests long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value of an asset or group of assets may not be recoverable. During the three months ended March 31, 2020, as a result of a decline in expected future cash flows and the effect of COVID-19 related to certain other nuclear legacy manufacturing assets in the U.S. segment, the Company determined certain impairment triggers had occurred. Accordingly, the Company performed an undiscounted cash flow analysis as of March 31, 2020. Based on the undiscounted cash flow analysis, the Company determined that the manufacturing assets had net carrying values that exceeded their estimated undiscounted future cash flows. The Company then estimated the fair values of the asset group based on their discounted cash flows. The carrying value exceeded the fair value and as a result, the Company recorded a non-cash impairment of $7.3 million for the nine months ended September 30, 2020 in cost of goods sold in the condensed consolidated statement of operations.
