We performed our annual evaluation of goodwill and indefinite life intangible assets for impairment as of the beginning of the second quarter of fiscal 2025 and concluded that these assets are not impaired. For our annual evaluation, we performed qualitative tests for our Intelligent Devices, Software & Control, and Lifecycle Services (excluding Sensia) reporting units and a quantitative test for our Sensia reporting unit. We also assessed the changes in events and circumstances subsequent to our annual test and concluded that no triggering events, which would require interim quantitative testing, occurred.
