During the nine months ended September 30, 2022, the Company performed an impairment review of the customer relationships intangible assets obtained in its 2018 acquisition of Dealflo Limited (“Dealflo”). The impairment review was triggered by the Company’s July 2022 notification to customers regarding its intent to gradually sunset its Dealflo solution in the months leading up to December 31, 2023. As a result, substantially all Dealflo solution customer contracts will terminate on or before December 31, 2023. The results of the impairment review indicated that the carrying value of the Dealflo customer relationships exceeded the fair value, and the Company recorded a $3.8 million impairment charge on the entire remaining value of the asset during the three months ended September 30, 2022. The charge is included in “Impairment of intangible assets” on the condensed consolidated statements of operations.

There was no additional impairment of intangible assets recorded during the nine months ended September 30, 2023 and 2022.
