Segment Reporting [Abstract]

Segment Information

21.  Segment Information

The Company has four reportable segments, which are described in Note 1. The Company evaluates the performance of its reportable segments based on their sales and operating income. All corporate expenses are allocated to the Company’s operating segments using an allocation methodology prescribed by U.S. Government regulations for government contractors. Accordingly, all costs and expenses, except for the gains or losses related to business divestitures (which were not included in the Company’s segment performance measures), are included in the Company’s measure of segment profitability.

The tables below present net sales, operating income, depreciation and amortization and total assets by reportable segment.
