Every paragraph of this subtopic — scope, recognition, disclosure, and transition — was superseded by ASU 2014-09 (Revenue from Contracts with Customers). Milestone-type contingent consideration is now accounted for as variable consideration under ASC 606, subject to the constraint on variable consideration.","concepts":["milestone method","superseded
