Note 5 —    Acquired Intangible Assets and Goodwill

The carrying basis and accumulated amortization of recognized intangible assets, excluding intangible assets which have been fully amortized, are summarized in the following table:

	2025				2024
In Thousands	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Patents		24,715		24,608		24,715		24,533
Customer list		22,017		14,776		22,017		13,122
Trade names		20,535		2,438		18,636		1,875
		67,267		41,822		65,368		39,530

Amortization expense was $2.3 million and $2.8 million for 2025 and 2024, respectively. At December 31, 2025, the net carrying amount of trade names includes $7.8 million related to indefinite-lived intangible assets which are not amortized but are evaluated for impairment at least annually.

Estimated future amortization expense is summarized in the following table:

All Amounts in Thousands
2026	$	2,313
2027		2,227
2028		1,576
2029		1,469
2030		1,284
Thereafter		8,792
Subtotal		17,661
Indefinite-lived intangible asset balance		7,784
Total	$	25,445

Consistent with our operating segment conclusion, we have concluded one reporting unit exists and all goodwill and indefinite lived intangibles are allocated to that reporting unit. There were no changes to the carrying amount of goodwill in 2025 or 2024.
