[1] Acquired in-process research and development (“IPR&D”) is an intangible asset accounted for as an indefinite-lived asset until the completion or abandonment of the associated research and development effort. If the research and development effort associated with the IPR&D is successfully completed, then the IPR&D intangible asset will be amortized over its estimated useful life to be determined at the date the effort is completed. The development effort on the IPR&D intangible asset is expected to be completed by the first half of fiscal year 2016.
