Variable Interest Entity, Measure of Activity [Abstract]
Veloce	Veloce On June 20, 2012 (the “Closing Date”), the Company completed its acquisition of Veloce pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”). Veloce has been developing specific technology for the Company. The terms of the Merger Agreement include the payment of the total consideration, payable to holders of Veloce common stock options that were vested on the Closing Date and holders of Veloce common stock and stock equivalents (collectively “Veloce Equity Holders”), and to Veloce stock equivalents that have not yet been allocated to individuals (“Unallocated Veloce Units”). The Merger Agreement further provides for payments of additional merger consideration contingent upon the achievement of certain post-closing product development milestones relating to the Veloce development project. The total estimated consideration to be paid was based upon the benchmarks achieved during technology simulations that were performed during the third quarter of fiscal 2013 and correlating the results of the technology simulations to the contractual terms included in the Merger Agreement. As a result of higher than expected benchmarks achieved during technology simulations, the total estimated consideration to be paid was updated during fiscal 2013 from a previous estimated maximum of approximately $135.0 million to the contractual maximum of $178.5 million. Significant judgment was required in assessing when a performance milestone was probable of achievement and estimating the percentage of completion of the milestone and the timing of when the performance milestones were completed. These determinations were based on discussions with internal technical personnel that addressed various qualitative and quantitative factors, including, but not limited to, overall complexity associated with the assessment, stage of development, progress made to date, results of testing and consideration as to the nature of the remaining development work. Veloce completed all three performance milestones relating to the project as of March 31, 2014. The consideration relating to the three performance milestones, excluding the value allocated to the Unallocated Veloce Units, in the amount of $169.3 million, has been recognized as research and development expense through March 31, 2014 compared to $126.6 million as of March 31, 2013. During the twelve months ended March 31, 2014 and 2013, as part of the above arrangement, the Company paid approximately $63.7 million and $16.5 million, respectively, in cash and issued approximately 6.7 million shares and 3.0 million shares, respectively, valued at approximately $57.3 million and $16.6 million, respectively. The consideration that the Company will be obligated to pay will be allocated equally to each of the Veloce Equity Holders and the Unallocated Veloce Units. The Company is contractually required to distribute all Unallocated Veloce Units within a certain time period. During the twelve months ended March 31, 2014, the Company distributed an additional 0.5 million Unallocated Veloce Units which had a related expense of $5.9 million. Veloce Equity Holders subject to vesting requirements will receive their distribution upon satisfaction of such vesting requirements. 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. Recognition of these costs as expense occurred 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 March 31, 2014, 0.9 million Unallocated Veloce Units had not been allocated, and the maximum potential additional expense to be recognized associated with these Unallocated Veloce Units was approximately $9.2 million. Total R&D expenses recognized related to Veloce were approximately $42.7 million and $66.2 million during the twelve months ended March 31, 2014 and 2013, respectively. The Veloce accrued liability included on the Consolidated Balance Sheets is based upon the amount of R&D expense recognized in connection with the development of the Veloce performance milestones less amounts paid either in cash or in common stock. Veloce consideration that has been accrued as of March 31, 2014, is classified as long-term if payments of the consideration are expected to occur beyond a 12 month period.
