Goodwill And Intangible Assets Disclosure [Abstract]

6. Goodwill and Other Intangible Assets

Changes in the carrying value of goodwill from December 31, 2014 to December 31, 2016 are as follows (in thousands):

Goodwill – December 31, 2014	$	650,778
Additions		25,050
Foreign currency translation and other adjustments ⁽¹⁾		(18,157	)
Goodwill – December 31, 2015		657,671
Additions		23,191
Foreign currency translation and other adjustments⁽¹⁾		(67,527	)
Goodwill – December 31, 2016	$	613,335

⁽¹⁾

The decreases are primarily related to translation losses on goodwill associated with the acquisition of NaturalMotion denominated in British pounds. Also includes the impact of adjustments to goodwill resulting from changes in net assets (liabilities) acquired and other adjustments, pursuant to our business combinations policy.

The details of our acquisition-related intangible assets are as follows (in thousands):

	December 31, 2016
	Gross Carrying		Accumulated			Net Book
	Value		Amortization			Value
Developed technology	$	150,826	$	(132,123	)	$	18,703
Trademarks, branding and domain names		16,290		(10,063	)		6,227
Acquired lease intangibles		5,708		(5,208	)		500
Total	$	172,824	$	(147,394	)	$	25,430

Our updated financial forecast as of September 30, 2016, indicated a reduction of future undiscounted cash flows for certain games associated with developed technology previously acquired from Rising Tide and Zindagi. As a result, we performed an impairment analysis and determined the estimated fair values of Rising Tide’s and Zindagi’s intangible assets to be $18.2 million and $2.4 million lower, respectively, than their carrying values as of September 30, 2016. Accordingly, we recorded this amount as an impairment charge in our consolidated statements of operations for the nine months ended September 30, 2016.

	December 31, 2015
	Gross Carrying		Accumulated			Net Book
	Value		Amortization			Value
Developed technology	$	174,970	$	(118,940	)	$	56,030
Trademarks, branding and domain names		16,290		(9,210	)		7,080
Acquired lease intangibles		5,708		(4,802	)		906
Total	$	196,968	$	(132,952	)	$	64,016

These assets include $6.1 million of indefinite-lived intangible assets. The remaining assets (excluding the indefinite-lived intangible assets) were, and continue to be, amortized on a straight-line basis. As of December 31, 2016, the weighted-average remaining useful lives of all identified acquired intangible assets are 2.4 years for developed technology, 0.2 years for trademarks, branding, and domain names, and 3.3 years for acquired lease intangibles. Amortization expense of intangible assets for 2016, 2015 and 2014 were $29.0 million, $27.4 million and $24.6 million, respectively. As of December 31, 2016, future amortization expense related to the intangible assets is expected to be recognized as shown below (in thousands):

Year ending December 31:
2017	$	9,718
2018		4,446
2019		2,811
2020		2,199
