Segment Data Our revenues are derived from three operating segments: (i) refining and marketing, (ii) asphalt and (iii) retail. The reportable operating segments are strategic business units that offer different products and services. The segments are managed separately as each segment requires unique technology, marketing strategies and distinct operational emphasis. Each operating segments performance is evaluated primarily based on operating income. (a) Refining and Marketing Segment Our refining and marketing segment includes a sour crude oil refinery located in Big Spring, Texas, a light sweet crude oil refinery located in Krotz Springs, Louisiana, and heavy crude oil refineries located in Paramount, Bakersfield and Long Beach, California (the California refineries).

Our California refineries have not processed crude oil since 2012 due to the high cost of crude oil relative to product yield and low asphalt demand. Beginning in February 2016, our renewable fuels project, AltAir, began commercial production. We sell motor fuels under the Alon brand through various terminals to supply 632 Alon branded retail sites, including our retail segment convenience stores. In addition, we sell motor fuels through our wholesale distribution network on an unbranded basis.
