Other Intangible Assets

Note 8—Other Intangible Assets

The Company’s other intangible assets consist of customer relationships which were obtained through acquisitions and are recorded at their fair values at the date of acquisition. Intangible assets with determinable lives are amortized on a straight-line basis over their estimated useful lives. The customer relationships have a weighted-average amortization period of approximately 10 years.

The following table sets forth the estimated amortization expense for intangibles subject to amortization for the remainder of 2021, the following five fiscal years and thereafter:

Period/Year	Total Amortization Expense
	(in thousands)
April 1 to December 31, 2021	$	3,124
2022	$	4,165
2023	$	3,169
2024	$	2,035
2025	$	2,035
2026	$	2,035
Thereafter	$	583

Amortization expense for both the three months ended March 31, 2021 and 2020 was $1.0 million.
