⁽¹⁾	During the three months ended September 30, 2019, we acquired Andersch and its related intangible assets within our Corporate Finance & Restructuring segment.

Other intangible assets with finite lives are amortized over their estimated useful lives. We recorded amortization expense of $2.1 million and $5.8 million for the three and nine months ended September 30, 2019, respectively, and $2.0 million and $6.3 million for the three and nine months ended September 30, 2018, respectively.

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



Year	As of September 30, 2019 ⁽¹⁾
2019 (remaining)	$	2,362
2020	9,436
2021	8,924
2022	7,156
2023	3,730
Thereafter	4,539
	$	36,147

⁽¹⁾

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