Goodwill is recorded at cost and tested for potential impairment at least annually. Goodwill was $26.3 million as of June 29, 2019 and $26.4 million as of December 29, 2018. During the three-month period ended June 29, 2019 an immaterial purchase price adjustment was recorded resulting in an immaterial decrease to Goodwill for the 4D acquisition in 2018.

Intangible assets are recorded at cost, less accumulated amortization. Certain of the Company’s intangible assets are denominated in foreign currencies. The aggregate $68,000 increase in the adjusted cost basis of the Company’s intangible assets as of June 29, 2019, as compared with December 29, 2018, was due to foreign currency movements. Such foreign currency movements also increased the June 29, 2019 balance of accumulated amortization of intangible assets by $68,000 as compared with December 29, 2018. During the three months ended June 29, 2019 the Company reclassified $0.5 million of in-process research and development to developed technology as the underlying technology was complete and incorporated into certain products sold. Intangible assets as of June 29, 2019 and December 29, 2018 consisted of the following (in thousands):

	June 29, 2019
	Adjusted cost		Accumulated amortization			Net carrying amount
Developed technology	$	36,512	$	(17,527	)	$	18,985
Customer relationships		6,541		(2,057	)		4,484
Trade name		1,500		(58	)		1,442
In-process research and development		900		—			900
Total	$	45,453	$	(19,642	)	$	25,811

	December 29, 2018
	Adjusted cost		Accumulated amortization			Net carrying amount
Developed technology	$	35,954	$	(16,532	)	$	19,422
Customer relationships		6,531		(1,519	)		5,012
Trade name		1,500		(8	)		1,492

Total	$	45,385	$	(18,059	)	$	27,326

The amortization of finite-lived intangibles is computed using the straight-line method. Estimated remaining lives of finite-lived intangibles range from less than one year to fifteen years. The total intangible amortization expense for the three and six months ended June 29, 2019 was $0.8 million and $1.5 million, respectively, and for the three and six months ended June 30, 2018 was $35,000 and $70,000, respectively.

There were no impairment charges related to intangible assets recorded during the six months ended June 29, 2019 and June 30, 2018.

The estimated future amortization expense of finite intangible assets as of June 29, 2019 is as follows (in thousands):

Fiscal Years	Amounts
2019 (remainder)	$	1,376
2020		2,960
2021		2,960
2022		2,960
2023		2,960
Thereafter		11,695
Total future amortization expense	$	24,911

In-process research and development of $0.9 million has been omitted from the above table as its estimated useful life is indeterminant at June 29, 2019. It will be tested for potential impairment, along with Goodwill, until its estimated useful life becomes finite.
