On January 31, 2020, the Company completed an annual review of goodwill and other intangible assets. Based on a review of qualitative factors at that time, 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 at that time, it was determined it was more likely than not that the fair value of our Klein reporting unit was less than it's carrying value. Accordingly, we recorded an impairment of approximately $760,000 related to indefinite lived intangible assets in the Klein reporting unit as of January 31, 2020. Due to the economic impact of the COVID-19 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. The impairment of goodwill indicated a possible impairment of other intangible assets. Accordingly, the Company completed a quantitative analysis of the other intangible assets as of April 30, 2020, noting that the undiscounted future cash flows exceeded their carrying value and no related impairment was recorded. Subsequent to April 30, 2020 there have been no substantive indicators of additional impairment. Aggregate amortization expense was $1.3 million and $1.3 million for the nine months ended October 31, 2020 and 2019, respectively. As of October 31, 2020, future estimated amortization expense related to amortizable intangible assets was estimated to be (in thousands):
For fiscal years ending January 31 |
2021 | $ | 423 |
2022 | 1,232 |
2023 | 1,087 |
2024 | 1,003 |
2025 | 730 |
Thereafter | 2,356 |
Total | $ | 6,831 |
