[1] | Initially, in-process research and development ("IPR&D") is classified as indefinite-lived assets until completion or abandonment. Therefore, amortization of IPR&D does not begin until the technological and market risk(s) no longer exist. During the interim, IPR&D intangibles are subject to annual testing for impairment or when there are indicators of impairment.
