(1) Acquired in-process research and development (“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 six months ended April 27, 2013, the IPRD intangible asset was not amortized due to the current stage of the associated research and development effort.

(2) During the six months ended April 27, 2013, $69.4 million of intangible assets became fully amortized and, therefore, were removed from the balance sheet.
