(1) Intangible assets acquired in a business combination that are in-process and used in research and development activities are considered indefinite-lived until the completion or abandonment of the research and development efforts. Once the research and development efforts are completed, we determine the useful life and begin amortizing the assets. All in-process research and development assets that were open as of December 31, 2024 were completed and reclassified to developed technology and began amortizing in 2025.
