Approximately $923,000 of the gross carrying amount of intangible assets, primarily in proprietary rights, are related to technology development projects that have not yet been completed. As a result, these intangible assets are not currently being amortized. On January 31, 2022, the Company completed an annual review of amortizable intangible assets. Based on a review of qualitative factors it was determined that there were no events or changes in circumstances indicating that the carrying value of amortizable intangible assets was not recoverable. During the nine months ended October 31, 2022, there have been no substantive indicators of impairment. Aggregate amortization expense was $0.8 million and $1.0 million for the nine months ended October 31, 2022 and 2021, respectively. As of October 31, 2022, future estimated amortization expense related to amortizable intangible assets was estimated to be:
