Goodwill and Other Intangible Assets [Abstract]

Goodwill and Other Intangible Assets

Note 7.  Goodwill and Other Intangible Assets

Goodwill and other intangible assets with indefinite lives are not amortized, but instead are assessed for impairment, at least annually. The carrying amount of goodwill was $916.2 million and $913.8 million as of September 28, 2025 and December 31, 2024, respectively. The net change in goodwill from December 31, 2024 to September 28, 2025 is attributable to the effects of foreign exchange.

Acquired intangible assets subject to amortization as of September 28, 2025 and December 31, 2024 were as follows:

		Sep. 28, 2025				Dec. 31, 2024
	Weighted Average		Gross				Gross
	Useful Life		Carrying		Accumulated		Carrying		Accumulated
(in millions of dollars)	(Years)		Amount		Amortization		Amount		Amortization
Tradenames	34	$	221.4	$	66.4	$	221.5	$	63.0

	29	$	327.0	$	115.5	$	324.2	$	106.1

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 29 years. Estimated amortization expense is $3.0 million for the remainder of 2025, $46.0 million for 2026–2029 and $162.5 million thereafter.
