The increase in goodwill during 2023 was primarily driven by goodwill recognized from the 2023 Acquisitions. The increase in goodwill during 2022 was primarily driven by goodwill recognized from the 2022 Acquisitions, partially offset by foreign currency translation.

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

	December 31, 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	$	782.6	$	450.6	$	332.0	$	677.0	$	398.3	$	278.7
Proprietary technology	13		365.1		146.1		219.0		310.0		123.8		186.2
Backlog and other	1		114.1		99.4		14.7		86.9		86.8		0.1
Total intangible assets (definite-lived)	10		1,261.8		696.1		565.7		1,073.9		608.9		465.0
Trade names (indefinite-lived)			269.1				269.1		269.1				269.1
		$	1,530.9	$	696.1	$	834.8	$	1,343.0	$	608.9	$	734.1

The increase in the gross carrying amount of intangible assets in 2023 was primarily driven by customer relationships and proprietary technology resulting from acquisition accounting associated with certain 2023 Acquisitions. Amortization expense for the years ended December 31, 2023, 2022 and 2021 was approximately $86.0, $81.0 and $86.4, respectively, which included the amortization of acquired backlog of $12.4, $12.0, and $25.2, respectively, resulting from acquisitions in each respective year. As of December 31, 2023, amortization expense relating to the Company’s current intangible assets estimated for each of the next five fiscal years is approximately $93.0 in 2024 (which includes the estimated amortization of acquired backlog resulting from certain acquisitions that closed late in 2023), $68.9 in 2025, $67.3 in 2026, $60.5 in 2027, and $53.2 in 2028.
