The weighted average amortization period in the above table excludes fully amortized intangible assets.

Amortization expense for the fiscal years ended July 31, 2020, 2019 and 2018 was $21,595,000, $18,320,000 and $21,075,000, respectively.

The estimated amortization expense consists of the following for the fiscal years ending July 31:


2021	$	21,276,000
2022	19,648,000
2023	19,648,000
2024	19,021,000
2025	18,918,000

We review net intangible assets with finite lives for impairment when an event occurs indicating the potential for impairment. In light of the COVID-19 pandemic, during the fiscal year ended July 31, 2020, we evaluated whether our long-lived assets, including intangibles with finite lives, were impaired. Based on our assessment, we believe that the carrying values of our net intangible assets were recoverable as of July 31, 2020. However, if current poor business conditions further deteriorate, we may be required to record impairment losses, and or increase the amortization of intangibles in the future. Any impairment charges that we may record in the future could be material to our results of operations and financial condition.
