The Company reviews goodwill at least annually for potential impairment, as of October 1, and more frequently, if events or changes in circumstances suggest that impairment may exist. The Company performed its annual goodwill impairment testing as of October 1, 2024, and determined that no adjustments to the carrying value of goodwill were necessary as it was more likely than not that the fair values of our reporting units are above their carrying values and that no impairment had occurred. We have assessed the changes in events and circumstances through the quarter ended March 31, 2025, and have concluded that no triggering events have occurred that would require interim testing.
