Intangible Assets

Intangible assets, net of accumulated amortization, impairment charges and adjustments, are summarized as follows:



		As of September 30, 2015							As of December 31, 2014
(In millions)	Estimated Life	Cost		Accumulated Amortization			Net		Cost		Accumulated Amortization			Net
Out-licensed patents	13-23 years	$	543.3	$	(499.9	)	$	43.4	$	543.3	$	(481.7	)	$	61.6
Developed technology	15-23 years	3,005.3		(2,523.8		)	481.5		3,005.3		(2,396.8		)	608.5
In-process research and development	Indefinite until commercialization	735.6		—			735.6		314.1		—			314.1
Trademarks and tradenames	Indefinite	64.0		—			64.0		64.0		—			64.0
Acquired and in-licensed rights and patents	3-17 years	3,297.6		(440.9		)	2,856.7		3,280.4		(300.1		)	2,980.3
Total intangible assets		$	7,645.8	$	(3,464.6	)	$	4,181.2	$	7,207.1	$	(3,178.6	)	$	4,028.5

For the three and nine months ended September 30, 2015, amortization of acquired intangible assets totaled $98.1 million and $286.0 million, respectively, as compared to $122.4 million and $382.5 million, respectively, in the prior year comparative periods.

For the three months ended September 30, 2015, compared to the same period in 2014, the decrease in amortization of acquired intangible assets was primarily driven by higher expected lifetime revenues of AVONEX, partially offset by lower expected lifetime revenues of TYSABRI. Amortization of acquired intangible assets during the three months ended September 30, 2014 included a $16.2 million impairment loss related to one of our IPR&D intangible assets.

For the nine months ended September 30, 2015, compared to the same period in 2014, the decrease in amortization of acquired intangible assets was primarily driven by a decrease in AVONEX revenues during the comparative periods. Amortization of acquired intangible assets during the nine months ended September 30, 2014 included total impairment charges of $50.9 million related to one of our out-licensed patents and one of our IPR&D intangible assets.

Developed Technology

Developed technology primarily relates to our AVONEX product, which was recorded in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation in 2003. The net book value of this asset as of September 30, 2015 was $472.9 million.

IPR&D

IPR&D represents the fair value assigned to research and development assets that we acquire that have not reached technological feasibility at the date of acquisition. Upon commercialization, we will determine the estimated useful life. In connection with our acquisition of Convergence in February 2015, we acquired IPR&D programs with an estimated fair value of $424.6 million. This amount will be adjusted for foreign exchange rate fluctuations. For a more detailed description of this transaction, please read Note 2, Acquisitions to these condensed consolidated financial statements.

Acquired and In-licensed Rights and Patents

Acquired and in-licensed rights and patents primarily relate to our acquisition of the TYSABRI rights from Elan Corporation plc (Elan). Elan was acquired by Perrigo Company plc (Perrigo) in December 2013. The net book value of this asset as of September 30, 2015 was $2,797.5 million.

Estimated Future Amortization of Intangible Assets

Our amortization expense is based on the economic consumption of intangible assets. Our most significant intangible assets are related to our AVONEX and TYSABRI products. Annually, during our long-range planning cycle, we perform an analysis of anticipated lifetime revenues of AVONEX and TYSABRI. This analysis is also updated whenever events or changes in circumstances would significantly affect the anticipated lifetime revenues of either product.

Our most recent long range planning cycle was updated in the third quarter of 2015. Based upon this analysis, there was not a significant change in our expected rate of amortization for acquired intangible assets and the estimated future amortization is expected to be as follows:



(In millions)	As of September 30, 2015
2015 (remaining three months)	$	94.3
2016	348.8
2017	318.6
2018	291.0
2019	275.1
2020	269.1
Total	$	1,596.9

Goodwill

The following table provides a roll forward of the changes in our goodwill balance:



(In millions)
Balance, as of December 31, 2014	$	1,760.2
Increase to goodwill	649.4
Other	(0.7		)
Balance, as of September 30, 2015	$	2,408.9

The increase in goodwill during the nine months ended September 30, 2015 was related to $600.0 million in contingent payments achieved (exclusive of a $78.9 million tax benefit) to former shareholders of Fumapharm AG or holders of their rights and our acquisition of Convergence. Other includes changes related to foreign exchange rate fluctuations. For additional information related to future contingent payments to the former shareholders of Fumapharm AG or holders of their rights, please read Note 20, Commitments and Contingencies to these condensed consolidated financial statements. For additional information related to our acquisition of Convergence, please read Note 2, Acquisitions to these condensed consolidated financial statements.

As of September 30, 2015, we had no accumulated impairment losses related to goodwill.
