We completed the annual evaluation of the carrying values of our goodwill and other indefinite-lived intangible assets as of November 1, 2019. As a result of the decline in drilling activities and the projection of continued softness in the U.S. land market, as well as the decline in the quoted market prices of our common stock, we determined that it was more likely than not that the carrying value of our Fluids Systems reporting unit exceeded its estimated fair value such that goodwill was potentially impaired. As a result, we completed the evaluation to measure the amount of goodwill impairment determining a full impairment of goodwill related to the Fluids Systems reporting unit was required. As such, in the fourth quarter of 2019, we recorded an $11.4 million non-cash impairment charge to write-off all of the goodwill related to the Fluids Systems reporting unit. We also determined that the Mats and Integrated Services reporting unit did not have a fair value below its net carrying value and therefore, no impairment was required.

Our impairment test included a comparison of the carrying value of net assets of our reporting units, including goodwill, with their estimated fair values, which we estimate using a combination of a market multiple and discounted cash flow approach. Significant assumptions inherent in the evaluation include the estimated growth rates for future revenues and the discount rate. Our assumptions were based on historical data supplemented by current and anticipated market conditions.

Other intangible assets consisted of the following:

In October 2019, we completed the acquisition of Cleansorb, which resulted in additions to amortizable intangible assets of $8.3 million. See Note 2 for additional information.

Estimated future amortization expense for the years ended December 31 is as follows:



(In thousands)	2020		2021		2022		2023		2024		Thereafter		Total
Technology related	$	1,353	$	1,298	$	1,237	$	1,068	$	1,044	$	7,706	$	13,706
