Depreciation and amortization expense for the years ended December 31, 2022 and 2021, was approximately $1.6 million and $0.9 million, respectively. At December 31, 2022 and 2021, the gross book value of assets under finance leases was $2.8 million and $2.5 million, respectively, and is classified in "Laboratory equipment" in the table above. Impairment of Long-Lived Assets and Goodwill During the year ended December 31, 2022, the Company recorded an impairment charge of $0.4 million related to previously capitalized equipment used in research and development activities that were halted in the fourth quarter of 2022. The Company based the fair values of these assets on their anticipated disposal values, which is considered a Level 3 measurement. The impairment charge was classified within research and development expenses in the accompanying statements of operations. The Company determined that the sustained decrease in its market capitalization constituted an indicator of impairment and as a result, instead of performing a qualitative test, the Company chose to proceed directly to performing a quantitative test during the fourth quarter. The Company determined the fair value of the reporting unit using the discounted cash flow (DCF) method, which is considered a Level 3 measurement. In applying the DCF method, cash flows are estimated for a five-year financial forecast developed by management. A terminal value, which represents the value of additional cash flows into perpetuity, is also calculated. Cash flows are then discounted to present value at a discount rate commensurate with their risk. Based on this analysis, the carrying value of the reporting unit was in excess of the fair value and the goodwill was fully impaired. During the year ended December 31, 2022, the Company recorded an impairment charge of $5.5 million. The following table presents details of the Company's goodwill for the year ended December 31, 2022 (in thousands):
