Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Acquired Intangible Assets | O. GOODWILL AND ACQUIRED INTANGIBLE ASSETS Goodwill Goodwill is considered impaired when the carrying value of a reporting unit exceeds its estimated fair value. Teradyne performs its annual goodwill impairment test as required under the provisions of Accounting Standards Codification ("ASC") 350-10, “Intangibles—Goodwill and Other” on December 31 of each fiscal year unless there are negative qualitative factors relating to macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and other relevant events and changes during an interim period. The presence of such factors could under certain circumstances be a triggering event that causes us to perform a goodwill impairment test. In assessing these factors and as a result of deterioration of forecasted 2025 revenues and earnings, which are now expected to be a loss, the Company identified a triggering event for the Robotics reporting unit at June 29, 2025. Teradyne performed an interim quantitative analysis to determine if the fair value of the Robotics reporting unit had fallen below its carrying value using an income and market approach, which were weighted equally. The quantitative analysis performed as of June 29, 2025, required the use of key estimates including forecasted future cash flows and management’s anticipated business outlook for the reporting unit. The result of this analysis indicated the fair value of the reporting unit was substantially higher than its carrying value and no impairment was recorded to goodwill. During the period ended June 29, 2025, there were no triggering events identified at any of the Company’s other reporting units. As a result of the goodwill triggering event described above, Teradyne also performed an interim impairment test for our long-lived assets, including intangible assets, as of June 29, 2025. The fair value of the long-lived and intangible assets was determined based on the undiscounted cash flows method. No impairment resulted from these interim impairment tests. The changes in the carrying amount of goodwill by reportable segments for the six months ended June 29, 2025, were as follows:
