	Estimated future amortization
2024 (remaining six months)	$	1,484
2025		2,958
2026		557
2027		356
Thereafter		1,396
Total	$	6,751

Actual amortization expense to be reported in future periods could differ from these estimates as a result of acquisitions, divestitures, and asset impairments, among other factors.

No impairment losses were recorded against the other intangibles during each of the three months ended June 30, 2024 and 2023.

During the fourth quarter of 2023 and second quarter of 2024, the Company determined that there were no triggering events or circumstances to indicate that the carrying value of the finite-lived asset group may not be recoverable. Based on the assessment performed, we concluded that an impairment charge to finite-lived intangible assets was not required as of December 31, 2023 and June 30, 2024 and the useful lives remain appropriate.

No impairment losses were recorded against the goodwill during the three months ended June 30, 2024 and 2023.

During the fourth quarter of 2023 and second quarter of 2024, the Company's current and expected cash flows, and the macro-economic and industry conditions have not significantly changed, while the Company’s market capitalization materially increased since December 31, 2023. After assessing the totality of events or circumstances, the Company determined that there were no events or circumstances in the fourth quarter of 2023 and second quarter of 2024 that indicated that the fair value of a reporting unit is more likely than not less than its carrying amount. Therefore, an impairment charge to goodwill was not required as of December 31, 2023 and June 30, 2024.

Certain future events and circumstances could result in changes to our assumptions and judgments used in the impairment tests. A downward revision of these assumptions could cause the total fair value of our goodwill and intangible assets to fall below carrying values and a non-cash impairment charge would be required. Such a charge may have a material effect on the consolidated financial statements.
