⁽¹⁾

Acquired IPR&D are intangible assets accounted for as indefinite-lived assets until the completion or abandonment of the associated research and development efforts. If the research and development efforts associated with the IPR&D are successfully completed, then the IPR&D intangible assets will be amortized over the estimated useful lives to be determined as of the date the efforts are completed. During the three months ended January 30, 2016, research and development efforts were completed on $12.3 million of the IPR&D intangible assets, and the completed IPR&D intangible assets are being amortized as Core/developed technology over an estimated useful life of five years. The research and development efforts associated with the remaining IPR&D intangible assets are expected to be completed in the second quarter of fiscal year 2016.


⁽²⁾	During the three months ended January 30, 2016, $1.0 million of finite-lived intangible assets became fully amortized and, therefore, were removed from the balance sheet.

⁽³⁾

The patent portfolio license was assigned an estimated useful life that reflects the Company’s consumption of the expected defensive benefits related to this license to certain patents. The method of amortization for the patent portfolio license reflects the Company’s estimate of the pattern in which these expected defensive benefits will be used by the Company and is primarily based on the mix of expiration patterns of the individual patents included in the license.
