Goodwill represents the excess of the cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. At both June 30, 2025 and December 31, 2024, we had $922.4 million of goodwill recorded in our Packaging segment, which represents the entire goodwill balance reported on our Consolidated Balance Sheets.

Intangible assets are primarily comprised of customer relationships and trademarks and trade names. The weighted average remaining useful life, gross carrying amount, and accumulated amortization of our intangible assets were as follows (dollars in millions):


	June 30, 2025						December 31, 2024
	Weighted Average Remaining Useful Life (in Years)		Gross Carrying Amount		Accumulated Amortization		Weighted Average Remaining Useful Life (in Years)		Gross Carrying Amount		Accumulated Amortization
