Note 18—Business Segment Information
The Company has two reportable business segments: GRE and GREW. GRE owns and operates REPs, including IDT Energy, Residents Energy, TSE, Southern Federal and Evergreen Energy, Mirabito. Its REP businesses resell electricity and natural gas to residential and small business customers in the Eastern and Midwestern United States and Texas. GREW develops, constructs and operates utility-scale solar energy projects, distributes solar panels, offers energy procurement and advisory services and also markets alternative products and services complementary to its energy offerings. Corporate costs include unallocated compensation, consulting fees, legal fees, business development expenses and other corporate-related general and administrative expenses. Corporate does not generate any revenues, nor does it incur any cost of revenues.
The Company’s reportable segments are distinguished by types of service, customers and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision-maker ("CODM"), its chief executive officer.
The CODM uses segment income (loss) from operations to allocate resources for each segment. The CODM considers revenues and income (loss) from operations to assess performance and make decisions about allocating resources to the segments.
The accounting policies of the segments are the same as the accounting policies of the Company as a whole. There are no significant asymmetrical allocations to segments.
Operating results for the business segments of the Company were as follows:
