Cumulative aggregate adjustments losses																																																																		37													69													48
Adjustment description																																																																		The Platform Systems sector adjustments are primarily due to: (1) losses of $37 million on two aircraft modification contracts and two contracts for rotary wing sub-assemblies and parts, and (2) write-offs of deferred costs of $15 million to design and test aerostructures for a new commercial aircraft.
Write-offs of deferred costs																																																																		15
