Segment Reporting [Abstract]  
SEGMENT INFORMATION
15.     SEGMENT INFORMATION
We report our results in two reportable segments: CSG and EISG. Our operating segments were determined based primarily on how the Chief Operating Decision Maker (“CODM”), President and Chief Executive Officer, views and evaluates our operations. Other factors, including market separation and customer specific applications, go-to-market channels, products and services, and manufacturing are considered in determining the formation of these operating segments.
The CODM is regularly provided with and reviews segment revenues and segment income from operations to support decision-making, set strategic goals, allocate resources, and evaluate each segment’s progress against the company’s plan. The CODM also reviews and approves budgets, including capital expenditures, at the segment level. The segment results are not necessarily in conformity with GAAP and exclude items such as share-based compensation expense, amortization of acquisition-related balances, acquisition and integration costs, restructuring costs, interest income, interest expense, and other items.
The following table reflects information related to our reportable segments:
