For accounting purposes, the costs incurred in connection with the development milestones relating to Veloce are considered compensatory and are recognized as R&D expense. These costs are recognized in the Condensed Consolidated Statement of Operations under R&D expense in the periods when certain development and performance milestones became probable of achievement and were deemed earned. However, the value allocated to the Unallocated Veloce Units will not be recognized as R&D expense until distribution of the underlying units occurs. As of December 31, 2014, 0.1 million Unallocated Veloce Units had not been allocated, and the maximum potential additional expense to be recognized associated with these Unallocated Veloce Units is approximately $2.1 million. Total R&D expenses recognized related to Veloce were zero and approximately $7.1 million during the three and nine months ended December 31, 2014, respectively, and approximately $2.9 million and $42.7 million during the three and nine months ended December 31, 2013, respectively. Veloce consideration that has been accrued as of December 31, 2014 is classified as long-term if payments of the consideration are expected to occur beyond a 12 month period.
