Amortization expense recorded on intangible assets for the fiscal years ended June 30, 2026, 2025 and 2024 was $280 million, $303 million, and $288 million, respectively. The technology intangible assets are being amortized over a range of 60 to 240 months with a weighted-average remaining life of approximately 109 months, and the amortization is recorded in Cost of goods sold in our Consolidated Statements of Earnings (Loss). The customer lists are being amortized over 60 to 192 months with a weighted-average remaining life of approximately 127 months, and the amortization is recorded in SG&A in our Consolidated Statements of Earnings (Loss).

Amortization expense in the fiscal year ended June 30, 2025 includes a total of $17 million of impairment charges in the Industrial segment related to the abandonment of certain purchased technology and licenses, of which $14 million was recorded in Cost of goods sold and $3 million was recorded in R&D in our Consolidated Statements of Earnings (Loss). No impairment charges were included in amortization expense during the fiscal years ended June 30, 2026 or 2024.

In the fourth quarter of fiscal year 2026, we completed our annual impairment test of our indefinite-lived Coherent trade name, which had a carrying value of $430 million. Based on the results of the assessment, we concluded that the trade name was not impaired.

The estimated amortization expense for existing intangible assets for each of the five succeeding years is as follows ($000):
