Effective November 1, 2024, the Measurement and Control Solutions ("MCS") division was transferred from the Industrial Precision Solutions ("IPS") segment to the Advanced Technology Solutions ("ATS") segment due to an organizational change and determination that the economic and business characteristics of MCS better aligned with the Company’s ATS segment. The division transfer above reflects the transfer of goodwill from IPS to ATS as a result of this change.
In the first quarter of 2025, the Company also reassessed its reporting units for purposes of annual goodwill impairment testing due to a number of recent developments, including the status of integration activities associated with several significant acquisitions over the last few years and changes in the management of divisions, such as the transfer of MCS to the ATS segment. As a result of this reassessment and in consideration of the Company's management reporting structure, economic characteristics of the divisions and nature of the products and services of those divisions, the Company determined its reporting units should be the same as its operating segments: ATS, IPS and MFS. In accordance with ASC 350, Intangibles - Goodwill and Other, the Company properly assessed for indicators of impairment of goodwill at the time of the reporting unit change, concluding that no impairment existed.
