Disaggregation of Revenue [Abstract]

Disaggregation of Revenue [Table Text Block]

The following tables present revenues on a disaggregated basis, in a manner that reconciles with the Company's reportable segment disclosures, for the following categories: product versus service type, customer type, contract type, and major program. Certain prior year amounts have been reclassified. See Note 8: Segment Information. The Company believes that this level of disaggregation provides investors with information to evaluate the Company’s financial performance and provides the Company with information to make capital allocation decisions in the most appropriate manner.
