Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

The Company accounts for goodwill in accordance with the authoritative guidance, which requires that goodwill and certain intangible assets are not amortized, but are subject to an annual impairment test. The Company performed a qualitative assessment in connection with its annual goodwill impairment test in the fourth quarter of 2018. As a result of the qualitative analysis, a quantitative impairment test was not deemed necessary. There was no impairment of goodwill or indefinite lived intangible assets as a result of the annual impairment test analysis completed during the fourth quarter of 2018.

The following table presents the change in goodwill during the six months ended June 30, 2019 (in thousands):



	Balance at January 1, 2019		Additions		Other				Balance at June 30, 2019
Goodwill	$	1,802,670	$	—	$	(2,395	)	(1)	$	1,800,275


(1)	Amount relates to adjustments to the purchase price allocation associated with 2018 acquisitions.

Intangible Assets

The Company has intangible assets which were primarily acquired in conjunction with business combinations and technology purchases. Intangible assets with finite lives are recorded at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally three to seven years, except for patents, which are amortized over the lesser of their remaining life or seven to ten years. In-process R&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When in-process R&D projects are completed, the corresponding amount is reclassified as an amortizable intangible asset and is amortized over the asset's estimated useful life.

Intangible assets consist of the following (in thousands):



	June 30, 2019				December 31, 2018
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Product related intangible assets	$	750,832	$	622,078	$	746,152	$	601,993
Other	227,923		211,629		227,922		204,894
Total	$	978,755	$	833,707	$	974,074	$	806,887

Amortization of product-related intangible assets, which consists primarily of product-related technologies and patents, was $9.8 million and $11.5 million for the three months ended June 30, 2019 and 2018, respectively, and $20.1 million and $22.5 million for the six months ended June 30, 2019 and 2018, respectively, and is classified as a component of Cost of net revenues in the accompanying condensed consolidated statements of income. Amortization of other intangible assets, which consist primarily of customer relationships, trade names and covenants not to compete was $3.2 million and $4.0 million for the three months ended June 30, 2019 and 2018, respectively, and $6.7 million and $7.7 million for the six months ended

June 30, 2019 and 2018, respectively, and is classified as a component of Operating expenses in the accompanying condensed consolidated statements of income.

The Company monitors its intangible assets for indicators of impairment. If the Company determines impairment has occurred, it will write-down the intangible asset to its fair value. For certain intangible assets where the unamortized balances exceeded the undiscounted future net cash flows, the Company measures the amount of the impairment by calculating the amount by which the carrying values exceed the estimated fair values, which are based on projected discounted future net cash flows.

Estimated future amortization expense of intangible assets with finite lives as of June 30, 2019 is as follows (in thousands):

2019 (remaining six months)	$	24,676
2020	39,148
