As of January 31, 2022, the Company completed its annual review of intangible assets. Based on a review of qualitative factors it was determined it was more likely than not that the fair value of our Seamap and Klein reporting units was greater than their carrying value. As a result, we did not record an impairment charge related to intangible assets in the Seamap and Klein reporting units in fiscal 2022.

Based on a review of qualitative factors it was determined it was more likely than not that the fair value of our Seamap reporting unit was greater than its carrying value. Based on a review of qualitative and quantitative factors it was determined it was more likely than not that the fair value of our Klein reporting unit was greater than its carrying value. Accordingly, we did not record an impairment charge related to intangible assets in the Seamap and Klein reporting units in fiscal 2021. As of January 31, 2021, the Company has recorded impairment expense equal to 100% of the gross carrying amount of goodwill. As a result, no further review of goodwill is required. Due to the economic impact of the global pandemic, the decline in oil prices during the three months ended April 30, 2020, and a decline in the market value of the Company’s equity securities, the Company performed a quantitative review of the Seamap reporting unit and concluded that goodwill had been impaired. As a result, the Company recorded an impairment expense of approximately $2.5 million related to goodwill in the Seamap reporting unit during the quarter ended April 30, 2020. Aggregate amortization expense was $1.3 million, and $1.8 million for fiscal 2022 and fiscal 2021, respectively. As of January 31, 2022, future estimated amortization expense related to amortizable intangible assets is estimated to be (in thousands):
