SEGMENT INFORMATION We have three reportable segments: Refining &amp; Marketing, Retail and Midstream. Each of these segments is organized and managed based upon the nature of the products and services it offers.  Refining &amp; Marketing  refines crude oil and other feedstocks at our refineries in the Gulf Coast, Mid-Continent and West Coast regions of the United States, purchases refined products and ethanol for resale and distributes refined products through transportation, storage, distribution and marketing services provided largely by our Midstream segment. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to our Retail business segment and to independent entrepreneurs who operate primarily Marathon  branded outlets.  Retail  sells transportation fuels and convenience products in the retail market across the United States through company-owned and operated convenience stores, primarily under the Speedway  brand, and long-term fuel supply contracts with direct dealers who operate locations mainly under the ARCO  brand.  Midstream  transports, stores, distributes and markets crude oil and refined products principally for the Refining &amp; Marketing segment via refining logistics assets, pipelines, terminals, towboats and barges; gathers, processes and transports natural gas; and gathers, transports, fractionates, stores and markets NGLs. The Midstream segment primarily reflects the results of MPLX. Segment income represents income (loss) from operations attributable to the reportable segments. Corporate administrative expenses, except for those attributable to MPLX, and costs related to certain non-operating assets are not allocated to the Refining &amp; Marketing and Retail segments. In addition, certain items that affect comparability (as determined by the chief operating decision maker) are not allocated to the reportable segments.
