Note 12—Goodwill and Other Intangible Assets

The changes in the carrying amount of goodwill by segment were as follows:

	Harsh				Interconnect
	Environment		Communications		and Sensor
	Solutions		Solutions		Systems		Total
Goodwill at December 31, 2022	$	1,667.1	$	2,908.1	$	1,870.9	$	6,446.1

Goodwill at June 30, 2023	$	1,734.2	$	2,902.0	$	1,882.4	$	6,518.6

The increase in goodwill during the first six months of 2023 was primarily driven by goodwill recognized from one acquisition that closed during the first quarter, and to a lesser extent, foreign currency translation.

Other than goodwill noted above, the Company’s intangible assets as of June 30, 2023 and December 31, 2022 were as follows:

	June 30, 2023							December 31, 2022
	Weighted	Gross				Net		Gross				Net
	Average	Carrying		Accumulated		Carrying		Carrying		Accumulated		Carrying
	Life (years)	Amount		Amortization		Amount		Amount		Amortization		Amount
Customer relationships	10	$	701.6	$	422.5	$	279.1	$	677.0	$	398.3	$	278.7
Proprietary technology	13		310.0		134.8		175.2		310.0		123.8		186.2
Backlog and other	1		92.4		92.3		0.1		86.9		86.8		0.1
Total intangible assets (definite-lived)	10		1,104.0		649.6		454.4		1,073.9		608.9		465.0
Trade names (indefinite-lived)			269.1				269.1		269.1				269.1
		$	1,373.1	$	649.6	$	723.5	$	1,343.0	$	608.9	$	734.1

The increase in the gross carrying amount of intangible assets in the first six months of 2023 was primarily driven by certain customer relationships and acquired backlog recognized as a result of the acquisition accounting associated with an acquisition that closed in the first quarter of 2023. Amortization expense for the three months ended June 30, 2023 and 2022 was approximately $18.1 and $16.8, respectively. Amortization expense for the six months ended June 30, 2023 and 2022 was approximately $41.2 and $34.8, respectively. Amortization expense for the six months ended June 30, 2023 includes $5.4 related to the amortization of acquired backlog resulting from the acquisition that closed in the first quarter of 2023. As of June 30, 2023, amortization expense relating to the Company’s current intangible assets estimated for the remainder of 2023 is approximately $36.0 and for each of the next five fiscal years is approximately $66.6 in 2024, $57.1 in 2025, $55.5 in 2026, $48.8 in 2027 and $41.5 in 2028.
