Program Development Costs
Program Development Costs	15. Program Development Costs Our Cargo Systems unit was selected in June 2005 to provide cargo loading systems for the Airbus A400M Military Transport Aircraft ("A400M"). During fiscal 2013, we delivered initial production units to Airbus, and we expect to deliver revenue-producing units beginning late in the first quarter or early in the second quarter of fiscal 2014. We expect our portion of the revenue from this program to be approximately $250 million through fiscal 2020, based on current sales projections of the A400M and the agreed-upon fixed pricing for the items that we are now responsible for under the amended contract. As of May 31, 2013 and 2012, we have capitalized, net of reimbursements, $130.9 million and $91.9 million, respectively, of costs associated with the engineering and development of the cargo system. Sales and related cost of sales will be recognized on the units of delivery method. In determining the recoverability of the capitalized program development costs, we have made certain judgments and estimates concerning expected revenues and the cost to manufacture the A400M cargo system. Differences between actual results and our assumptions may result in our not fully recovering our program development costs, which could adversely affect our operating results and financial condition.
