10. Intangible assets (cont'd): Additions to intangible assets in 2024 of $1,768,000 (2023 - $154,000) consist primarily of costs to expand and enhance the capabilities of the ERP management reporting software system. Amortization expense on intangible assets is allocated to research and product development expense or general and administration expense depending upon the nature of the underlying assets. During the year ended December 31, 2024, amortization of $759,000 (2023 - $1,696,000) was recorded. During the year ended December 31, 2024, the Corporation recognized impairment charges on intangible assets of $658,000 consisting of a write-down of certain information technology assets located in Denmark primarily as a result of the global corporate restructuring initiated in September 2024. During the year ended December 31, 2023, the Corporation recognized impairment charges on intangible assets of $2,266,000 in net loss from discontinued operations consisting of the write-down of technology intangible assets to their estimated fair value of $nil as a result of the restructuring and effective closure of operations of Ballard Motive Solutions in the U.K. (note 26).
