Segment Reporting [Abstract] |
Report of Business Segments | Report of Business Segments The Company reports its operations in two business segments: (i) the electric utility segment, which is engaged in the generation, transmission, distribution and sale of electric energy, and (ii) natural gas midstream operations segment. The natural gas midstream operations segment reflects the Company's equity interest in Enable since its formation on May 1, 2013. Prior to May 1, 2013, the Company reported the results of Enogex Holdings in two separate segments: the natural gas transportation and storage segment, and the natural gas gathering and processing segment. After the deconsolidation, these segments were combined into the natural gas midstream operations segment. The presentation of results for the three months ended March 31, 2013 have been revised to reflect this change. Equity in earnings of unconsolidated affiliates in the natural gas midstream operations segment includes OGE Energy's equity interest in Enable since May 1, 2013. Other than equity in earnings of unconsolidated affiliates, all amounts for the natural gas midstream operations segment represent the operation results of Enogex Holdings through April 30, 2013. Investment in unconsolidated affiliates in the natural gas midstream operations segment represents OGE Energy's investment in Enable at March 31, 2014. Other Operations primarily includes the operations of the holding company. Intersegment revenues are recorded at prices comparable to those of unaffiliated customers and are affected by regulatory considerations. In reviewing its segment operating results, the Company focuses on operating income and equity in earnings of unconsolidated affiliates as measures of segment profit and loss, and, therefore, has presented this information below. The following tables summarize the results of the Company's business segments during the three months ended March 31, 2014 and 2013.
