3. Intangible assets, net

Intangible assets, net, other than goodwill, consist of the following: 

The gross amounts associated with software developed for internal use primarily represent capitalized costs of internally developed software. The amounts relating to acquired proprietary technology, customer relationships, trade names, domain names, databases, and non-competition agreements primarily represent the fair values of intangible assets acquired as a result of the acquisition of Fluent, LLC, effective December 8, 2015; the acquisition of Q Interactive, LLC, effective June 8, 2016; the acquisition of substantially all the assets of AdParlor Holdings, Inc. and certain of its affiliates, effective July 1, 2019 (the "AdParlor Acquisition"); the acquisition of a 50% interest in Winopoly, LLC, effective April 1, 2020; the acquisition of a 100% interest in True North Loyalty, LLC, (the "True North Acquisition"), effective January 1, 2022 (see Note 11, Variable Interest Entity); and the consolidation of TAPP Influencers Corp. ("TAPP") effective January 9, 2023 (see Note 11, Variable Interest Entity).

During the second quarter of 2024, the Company determined that the effects of the expected decline in operations due to the impact of certain client relationships constituted a triggering event for the All Other reporting unit. The Company conducted an interim test of recoverability of its long-lived assets, which compared the projected undiscounted cash flows to the carrying value of the asset group. The results of this approach indicated that this long-lived asset was not recoverable and an impairment loss related to its customer relationships was to be calculated. The Company determined that based on the facts and circumstances, the remaining balance was impaired and recorded a non-cash impairment charge of its customer relationship intangible of $383 as of  June 30, 2024.

As of June 30, 2024, the Company had recorded a $597 impairment charge on its software developed for internal use which related to an immaterial business unit under the Fluent reporting unit that had met the held for sale criteria as of June 30, 2024.
