Segment Information

22.  Segment Information

The Company has four reportable segments, which are described in Note 1. The Company evaluates the performance of its operating segments and reportable segments based on their sales, operating income and operating margin. Corporate expenses are allocated to the Company’s operating segments using an allocation methodology prescribed by U.S. Government regulations for government contractors. Accordingly, segment results include all costs and expenses, except for goodwill impairment charges and certain other items that are excluded by management for purposes of evaluating the operating performance of the Company’s business segments.

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