The changes in the carrying amount of goodwill for the years ended December 31, 2020 and 2019, are as follows:


	2020		2019
Beginning of year	$	54,119	$	83,992

Impairment	—		(29,820)

The Company had $43,643 of cumulative impairment losses as of December 31, 2020 and 2019.

For the year ended December 31, 2019, during the Company's annual goodwill impairment test, the Company determined it was more-likely-than-not that the fair value of the Trans Ova reporting unit was less than its carrying amount. As a result, the Company compared the carrying amount of the Trans Ova reporting unit to the fair value and determined the carrying amount exceeded the fair value resulting in a $29,642 goodwill impairment charge for the excess carrying value. Additionally, the Company recorded $178 of goodwill impairment in conjunction with the closing of two of its reporting units during the third quarter of 2019.

See Note 20 for information regarding goodwill by reportable segment.

In the year ended December 31, 2018, the Company recorded a $16,027 loss related to the abandonment of certain developed technologies that the Company ceased using in the fourth quarter of 2018. The Company does not expect to use these technologies as a defensive asset or market them for sale in the future. Because these technologies were used in combination with other technologies, the identifiable cash flows did not result in an impairment loss; however, because the Company made a decision to abandon the assets, it recorded the charge to research and development expense.

Amortization expense was $7,593, $7,920 and $11,666 for the years ended December 31, 2020, 2019 and 2018, respectively. Estimated aggregate amortization expense for definite lived intangible assets is expected to be as follows:


2021	$	7,704
2022	6,908
2023	5,742
2024	5,432
2025	5,419
Thereafter	34,191
