Note 12: Collaborative Arrangements	Note 12: Collaborative Arrangements In view of the risks and costs associated with developing new engines, Pratt & Whitney has entered into certain collaboration arrangements in which costs, sales and risks are shared. Sales generated from engine programs, spare parts, and aftermarket business under collaboration arrangements are recorded as earned in our financial statements. Amounts attributable to our collaborative partners for their share of sales are recorded as an expense in our financial statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments to Pratt & Whitney for shared or joint program costs. The reimbursement of the collaborators' share of program costs is recorded as a reduction of the related expense item at that time. As of June 30, 2011, the collaborators' interests in all commercial engine programs ranged from 12% to 48%. Pratt & Whitney directs those programs and is the principal participant in all existing collaborative arrangements. There are no individually significant collaborative arrangements, and none of the individual partners' shares exceed 31% of an individual program.
