Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill represents the excess of the fair value of the consideration transferred over the value of net tangible and identifiable intangible assets of acquired businesses. Identifiable intangible assets acquired in business combinations are recorded based on their fair values on the date of acquisition.

During the first quarter of 2017, the Company completed the annual impairment test for goodwill and the indefinite-lived intangible asset and determined that these assets had not been impaired as of the test date, January 1, 2017. No other events or circumstances changed during the year ended December 31, 2017 that would indicate that the fair values of the Company's reporting unit and indefinite-lived intangible asset are below their carrying values.

The Company's intangible assets and estimated useful lives are classified as follows:



	December 31, 2017					December 31, 2016
(in thousands)	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization
Finite-lived intangible assets:
Developed software and core technologies (3 – 11 years)	$	365,317	$	(297,645	)	$	338,594	$	(275,130	)
Customer lists and contract backlog (5 – 15 years)	171,048		(104,522		)	159,549		(88,414		)

Indefinite-lived intangible assets:
Trade name	$	357				$	357

Amortization expense for the intangible assets reflected above was $49.8 million, $50.8 million and $58.1 million for the years ended December 31, 2017, 2016 and 2015, respectively.

As of December 31, 2017, estimated future amortization expense for the intangible assets reflected above is as follows:



(in thousands)
2018	$	39,162
2019	26,362
2020	25,449
2021	21,225
2022	16,197
Thereafter	28,873
Total intangible assets subject to amortization, net	157,268
Indefinite-lived trade name	357
Other intangible assets, net	$	157,625

The changes in goodwill during the years ended December 31, 2017 and 2016 are as follows:



(in thousands)	2017			2016
Beginning balance - January 1	$	1,337,215		$	1,332,348
Acquisitions	36,554			6,184
Adjustments⁽¹⁾	(111		)	(1		)
Currency translation	4,895			(1,316		)
Ending balance - December 31	$	1,378,553		$	1,337,215

⁽¹⁾ In accordance with the accounting for business combinations, the Company recorded adjustments to goodwill for the effect of changes in the provisional fair values of the assets acquired and liabilities assumed during the measurement period (up to one year from the acquisition date) as the Company obtained new information about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date.
