Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets and Goodwill

Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis each September 1st and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We completed our annual impairment tests of intangible assets and goodwill as of September 1, 2021, and determined there were no impairments. Our goodwill primarily relates to the Krausz reporting unit which was $91.2 million as of September 1, 2021.

Intangible Assets

Direct internal and external costs to develop software licensed by Technologies’ customers are capitalized and amortized over the 6-year estimated useful life of the software, beginning when the software is ready for its intended use. At September 30, 2021, the remaining weighted-average amortization period for this software was 1.8 years. Amortization expense related to such software assets was $3.3 million in each of our 2021, 2020 and 2019 fiscal years. Amortization expense for each of the next five years is scheduled to be $3.5 million in 2022, $2.7 million in 2023, $2.1 million in 2024, $1.1 million in 2025 and $0.5 million in 2026.

At September 30, 2021, the remaining weighted-average amortization period for business combination-related finite-lived customer relationships and technology intangible assets were 4.4 years and 4.5 years, respectively. Amortization expense related to these assets was $25.2 million, $24.9 million and $23.7 million for 2021, 2020 and 2019, respectively. Amortization expense for each of the next five years is scheduled to be $25.4 million in 2022, $24.8 million in 2023, $24.8 million in 2024, $5.2 million in 2025 and $4.4 million in 2026.
