Segment Reporting [Abstract] |
Business Segments | Business Segments AWR has three reportable segments, water, electric and contracted services, whereas GSWC has two segments, water and electric. On a stand-alone basis, AWR has no material assets other than its investments in its subsidiaries. All activities of GSWC, a rate-regulated utility, are geographically located within California. Activities of ASUS and its subsidiaries are conducted in California, Georgia, Florida, Maryland, New Mexico, North Carolina, South Carolina, Texas and Virginia. In September 2017, ASUS was awarded a new 50-year contract by the U.S. government for water and wastewater operations at Fort Riley located in Kansas. ASUS expects to assume operations at Fort Riley following the completion of a six-to-twelve-month transition period currently underway. Each of ASUS’s wholly owned subsidiaries is regulated, if applicable, by the state in which the subsidiary primarily conducts water and/or wastewater operations. Fees charged for operations and maintenance and renewal and replacement services are based upon the terms of the contracts with the U.S. government which have been filed, as appropriate, with the commissions in the states in which ASUS’s subsidiaries are incorporated. The tables below set forth information relating to GSWC’s operating segments, ASUS and its subsidiaries and other matters. Total assets by segment are not presented below, as certain of Registrant’s assets are not tracked by segment. The utility plant amounts are net of respective accumulated provisions for depreciation. Capital additions reflect capital expenditures paid in cash, and exclude U.S. government- and third-party contractor-funded capital expenditures for ASUS and property installed by developers and conveyed to GSWC.
