(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 or when there are indicators of impairment. If the IPRD project is successfully completed, then the IPRD intangible asset will be amortized over its estimated useful life to be determined at the date the project is completed. During the three months ended January 26, 2013, the IPRD intangible asset was not amortized due to the current stage of the associated research and development effort.
