Business Segments [Abstract]

Business Segments

3. BUSINESS SEGMENTS

Management evaluates segment performance based on Segment Income, which is defined as income from continuing operations net of income attributable to noncontrolling interests. Segment Income, as discussed below, includes intercompany revenues and expenses that are eliminated in the Condensed Consolidated Financial Statements. Certain governance costs are allocated to each of the segments. In addition, direct interest expense and income taxes are included in Segment Income.

Operating segments for each of the Duke Energy Registrants are determined based on information used by the chief operating decision maker in deciding how to allocate resources and evaluate the performance at each of the Duke Energy Registrants.

Products and services are sold between the affiliate companies and between the reportable segments of Duke Energy at cost. Segment assets as presented in the tables that follow exclude all intercompany assets.
