Impairment of technology and other non-financial assets
During the fourth quarter of fiscal 2024, the Company considered the impact of general economic headwinds, the re-baselining of its Defense and Security business and the reduced pursuit of certain types of opportunities as part of its review of impairment indicators for non-financial assets. As a result of this review, the Company recorded impairment charges totaling $35.7 million in the Defense and Security segment, consisting of $31.4 million of internally developed intangible assets and $4.3 million of simulators included in property, plant and equipment.
