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 2019, the following five fiscal years and thereafter:

Period/Year	Total Amortization Expense
	(in thousands)
July 1 to December 31, 2019	$	2,083
2020	$	4,165
2021	$	4,165
2022	$	4,165
2023	$	3,168
2024	$	2,035
Thereafter	$	4,654

Amortization expense for the three months ended June 30, 2019 and 2018 was $1.0 million and $1.1 million, respectively. Amortization expense for the six months ended June 30, 2019 and 2018 was $2.1 million and $2.2 million, respectively.
