Segment Reporting [Abstract]

Segment Reporting Disclosure

13. BUSINESS SEGMENTS

The Company has operating segments that are organized around three strategic business units consisting of EES, CSS and UBS. These operating segments are equivalent to the Company's reportable segments. The Company's CODM evaluates the performance of its operating segments based primarily on net sales, income from operations, and total assets.

Corporate expenses are incurred to obtain and coordinate financing, tax, information technology, legal and other related services. The Company also has various corporate assets which are reported in corporate. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are not allocated to the segments or reviewed on a segment basis. Corporate expenses are shown in the tables below to reconcile the reportable segments to the consolidated financial statements.

The following tables set forth financial information by reportable segment for the periods presented:
