(1) Excludes fully amortized intangible assets

The in-process research and development ("IPR&D") assets are classified as indefinite lived intangible assets that are not currently subject to amortization but are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. The IPR&D assets will be subject to amortization upon completion of their respective research projects and at the start of commercialization. The fair values assigned to IPR&D assets were determined using the income approach based on estimates and judgments regarding risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. If an IPR&D project is abandoned, the acquired technology attributable to the project will be expensed in the Condensed Consolidated Statement of Operations.

For the three and six months ended June 28, 2014, amortization expense of $4.4 million and $0.7 million, and $8.8 million and $1.4 million, respectively, was included in the cost of revenues and selling, and general and administrative expenses. For the three and six months ended June 29, 2013, amortization expense of $3.4 million and $0.8 million, and $7.0 million and $1.5 million, respectively, was included in cost of revenues and selling, general and administrative expenses.

Based on the carrying values of the finite-lived intangible assets recorded as of June 28, 2014 and assuming no subsequent additions to or impairment of the underlying assets, the remaining estimated annual amortization expense is expected to be as follows (in thousands):



Fiscal Year	Amount
2014	$	8,637
2015	12,739
2016	8,720
2017	2,551
2018	2,501
and thereafter	5,278
Total	$	40,426
