Intangible Assets with Finite Lives

At December 31, 2024 and 2023, the Company's intangible assets with finite lives were as follows:

(1) The impairment charges subsequently discussed resulted in the establishment of a new cost basis for certain intangible assets reflected in the table. Gross asset carrying values and accumulated amortization have been adjusted to reflect the new cost basis of intangible assets for which the carrying value was reduced due to impairment.

n/m - Disclosure deemed not meaningful as the remaining net carrying value of this intangible asset class is immaterial.

Impairment of Intangible Assets During the Year Ended December 31, 2024

As previously discussed in Note 2, during the three months ended September 30, 2024, the Company concluded that the carrying value of the primary asset group underlying the Company's core operations was impaired, resulting in the allocation of $31.2 million of the $42.3 million impairment charge to intangible assets. During the three months ended December 31, 2024, the Company concluded that the carrying value of the software asset group was not recoverable, resulting in an additional $1.2 million impairment charge to intangible assets. The impairment charges allocated to intangible assets reduced the carrying values of customer relationships, acquired technology, and trade names by $0.9 million, $23.2 million, and $8.3 million, respectively. All intangible asset impairment charges have been recorded within asset impairment charges on our consolidated statements of operations.

Impairment of Intangible Assets During the Year Ended December 31, 2023

Indefinite-Life Intangible Assets (Excluding Goodwill)

As of December 31, 2022, the Company's intangible assets reported on the consolidated balance sheet included an indefinite-life intangible asset balance of $5.4 million related to IPR&D recorded in connection with the October 4, 2022 acquisition of dp polar. During the three months ended December 31, 2023, in connection with both the inability to reach economically favorable contract terms with dp polar's first potential customer and the Company's broader efforts to reduce operating costs (including the restructuring initiatives described in Note 24), the Company decided to cease the development of this IPR&D for the foreseeable future. As the IPR&D was not capable of generating revenue or positive cash flows without further development, the Company recorded a charge of $5.6 million within asset impairment charges on our consolidated statement of operations for the year ended December 31, 2023 to write off the carrying value of this foreign currency denominated asset as of the date of impairment.

Impairment of Intangible Assets with Finite Lives

dp polar

The Company's decision to cease the development of the dp polar IPR&D (as discussed above) represented a triggering event that required an assessment of whether the carrying value of the broader dp polar asset group was recoverable. dp polar represented an asset group because its identifiable cash flows were largely independent of the cash flows of other groups of assets and liabilities within the Company.

As dp polar was not capable of generating revenue or positive cash flows without the continued development of its IPR&D, the Company concluded that dp polar's long-lived assets, including the remaining carrying value of the trade name intangible asset recorded when dp polar was acquired, were fully impaired. Accordingly, the Company recorded a charge of $3.8 million within asset impairment charges on our consolidated statement of operations for the year ended December 31, 2023 to write off dp polar's trade name.

Oqton MOS

During the three months ended September 30, 2023, the Company concluded that it was more likely than not that it would sell or otherwise dispose of a portion of its software business unit, Oqton MOS, that it had previously acquired. This software business unit represented a discrete asset group for accounting purposes, as its identifiable cash flows were deemed to be largely independent of the cash flows of other groups of assets and liabilities within the Company and its software business unit. Based upon the expectation to either sell or otherwise dispose of this asset group, the Company revised the related long-term cash flow forecast. The revised long-term cash flow forecast indicated that the carrying amounts of this asset group's long-lived assets, consisting primarily of product technology and trade name intangible assets recorded when the asset group was initially acquired, may not be recoverable. Accordingly, the carrying value of this asset group's long-lived assets was tested for impairment based upon an estimate of the associated discounted future cash flows. This fair value measurement approach required the use of Level 3 fair value measurement inputs, as defined in Note 23. As the present value of the estimated future cash flows expected to result from the use and eventual disposition of the asset group was less than the asset group's carrying value, the Company recognized a $13.6 million impairment charge during the year ended December 31, 2023, which reduced the carrying values of the asset group's acquired technology and trade name intangible assets to $0.

Amortization of Intangible Assets with Finite Lives

Amortization expense related to our intangible assets with finite lives was $12.7 million, $12.1 million and $15.5 million for the years ended December 31, 2024, 2023 and 2022, respectively. Amortization expense is estimated to be $1.8 million in 2025, $1.7 million in 2026, $1.7 million in 2027, $1.6 million in 2028, and $1.5 million in 2029.
