Segment Reporting [Abstract]

Schedule Of Operating Income Derived From Revenues And Expenses By Segment

At September 30, 2020, our operations are divided into two primary reportable segments. The Gas Distribution Operations segment provides natural gas service and transportation for residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland, Indiana and Massachusetts. The sale of the Massachusetts Business was completed on October 9, 2020. Refer to Note 6, "Assets and Liabilities Held for Sale," for further details. The Electric Operations segment provides electric service in 20 counties in the northern part of Indiana.

The following table provides information about our business segments. We use operating income as our primary measurement for each of the reported segments and make decisions on finance, dividends and taxes at the corporate level on a consolidated basis. Segment revenues include intersegment sales to affiliated subsidiaries, which are eliminated in consolidation. Affiliated sales are recognized on the basis of prevailing market, regulated prices or at levels provided for under contractual agreements. Operating income is derived from revenues and expenses directly associated with each segment.
