Other intangible assets with finite lives are amortized over their estimated useful lives. We recorded amortization expense of $2.3 million and $1.9 million for the three months ended March 31, 2020 and 2019, respectively.

We estimate our future amortization expense for our intangible assets with finite lives to be as follows:



Year	As of March 31, 2020 ⁽¹⁾
2020 (remaining)	$	6,939
2021	8,740
2022	6,944
2023	3,564
2024	2,177
Thereafter	2,218
	$	30,582

⁽¹⁾

Actual amortization expense to be reported in future periods could differ from these estimates because of new intangible asset acquisitions, impairments, changes in useful lives, or other relevant factors or changes.
