        All of our intangible assets as of March 31, 2012 were recorded in connection with the acquisition of ATL in July 2011. Intangible assets related to in-process research and development projects are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts. Intangible assets with finite useful lives are related to acquired developed technology and acquired rights in non-active collaboration agreements. Intangible assets with finite useful lives are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable. We amortize the finite lived intangible assets using the straight-line method, which approximates the pattern in which we expect to derive the benefits from the use of these assets. Intangible assets related to the developed technology are being amortized over seven years and the non-active collaboration agreements are being amortized over five years. The accumulated amortization of the developed technology and non-active collaboration agreements was $1,780,000 and $3,632,000, respectively, at March 31, 2012.
