Amortization expense for the three months ended January 31, 2022 and 2021 was $5,349,000 and $4,795,000, respectively. Amortization expense for the six months ended January 31, 2022 and 2021 was $10,698,000 and $10,361,000, respectively.

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


2022	$	21,589,000
2023	21,781,000
2024	21,154,000

We review net intangible assets with finite lives for impairment when an event occurs indicating the potential for impairment. Based on our last assessment, we believe that the carrying values of our net intangible assets were recoverable as of January 31, 2022. However, if business conditions 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.
