The following summarizes changes in the carrying value of goodwill by segment during the year ended September 30, 2025:

			Communications						Residential						Infrastructure Solutions						Commercial & Industrial						Total

Balance at September 30, 2025			$	12,336					$	51,370					$	44,124					$	—					$	107,830

Based on the results of our annual goodwill impairment assessment at September 30, 2025, we concluded the fair value of each of our reporting units exceeded its book value, and therefore we recorded no impairment charges for the year ended September 30, 2025.

As of September 30, 2025 and 2024, we had accumulated impairment losses of $6,976 related to our Commercial & Industrial segment.
