Goodwill and Intangible Assets Disclosure [Abstract]  
Goodwill and Other Intangible Assets GOODWILL AND OTHER INTANGIBLE ASSETS
Intangible assets, other than goodwill, include trademarks, patents, customer lists and product registrations. Intangible amortization expense was $138,000 and $150,000 in the second quarter of fiscal years 2022 and 2021, respectively. Intangible amortization expense was $253,000 and $305,000 in the first six months of fiscal years 2022 and 2021, respectively. Estimated intangible amortization for the remainder of fiscal year 2022 is $233,000. Estimated intangible amortization for the next five fiscal years is as follows (in thousands):
2023$262 
2024$126 
2025$102 
2026$99 
2027$96 

We have one acquired trademark recorded at a cost of $376,000 that was determined to have an indefinite life and is not amortized.

We performed our annual goodwill impairment analysis in the fourth quarter of fiscal year 2021 and no impairment was identified. There have been no triggering events that would indicate a new impairment analysis is needed. Although we have not identified any triggering events relating to goodwill or our intangibles, the ultimate effects of COVID-19 could change this assessment in the future.
