ASU 2010-17

In April 2010, the FASB issued ASU 2010-17, "Revenue Recognition – Milestone Method," which provides guidance on defining a milestone and determining when it may be appropriate to apply the milestone method of revenue recognition for research or development transactions. Research or development arrangements frequently include payment provisions whereby a portion or all of the consideration is contingent upon milestone events such as successful completion of phases in a drug study or achieving a specific result from the research or development efforts. An entity often recognizes these milestone payments as revenue in their entirety upon achieving the related milestone, commonly referred to as the milestone method. We adopted the amendments in ASU 2010-17 effective January 1, 2011 on a prospective basis. Our previous practices are consistent with the guidance in ASU 2010-17 and, in future research and development transactions, we will analyze the impact and, when the milestones are substantive, we will recognize them according to ASU 2010-17. Accordingly, the adoption of the provisions of ASU 2010-17 did not have any effect on our financial position, results of operations or cash flows.
