Completed IPRD	$ (9,300,000)

[1] Acquired IPRD is an intangible asset accounted for as an indefinite-lived asset until the completion or abandonment of the associated research and development effort. While accounted as an indefinite-lived asset, the IPRD intangible asset is subject to testing for impairment annually, as of the first day of the second fiscal quarter, and whenever events or changes in facts and circumstances indicate that it is more likely than not that IPRD is impaired. If the research and development effort associated with the IPRD is successfully completed, then the IPRD intangible asset will be amortized over its estimated useful life to be determined at the date the effort is completed. During the fiscal year ended November 1, 2014, development work was completed on $9.3 million of the IPRD intangible asset and this completed IPRD intangible asset is being amortized as Core/developed technology. The development effort on the remaining IPRD intangible asset is expected to be completed by the first half of fiscal year 2016.

[2] During the fiscal year ended November 1, 2014, $477.3 million of finite-lived intangible assets became fully amortized and, therefore, were removed from the balance sheet.
