On January 31, 2018, the Company completed an annual review of goodwill and other 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 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 not greater than its carrying value. Accordingly, we recorded an impairment of approximately $1.5 million related to the Klein reporting unit in the quarter ended January 31, 2018.

During the six months ended July 31, 2018 there have been no substantive indicators of additional impairment.

Amortizable intangible assets are amortized over their estimated useful lives of five to 15 years using the straight-line method. Aggregate amortization expense was $889,000 and $716,000 for the six months ended July 31, 2018 and 2017, respectively. As of July 31, 2018, future estimated amortization expense related to amortizable intangible assets was estimated to be:



For fiscal years ending January 31 (in thousands):
2019	$	902
2020	1,783
2021	1,636
2022	1,150
2023	964
2024 and thereafter	4,602
