The consideration relating to the three performance milestones, excluding the value allocated to Veloce stock equivalents that have not yet been allocated to individuals ("Unallocated Veloce Units"), in the amount of $176.4 million, has been recognized as research and development expense through September 30, 2014 compared to $166.3 million as of September 30, 2013.

Veloce consideration that has been accrued as of September 30, 2014 is classified as long-term if payments of the consideration are expected to occur beyond a 12 month period.
