We aggregate our operating units into three reportable segments: Refining, Logistics, and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consist of the following:


•	our corporate activities;


•	results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 9);


•	Alon's asphalt terminal operations; and


•	intercompany eliminations.

Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin. Segment contribution margin is defined as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization.

During the first quarter of 2020, we revised the structure of the internal financial information reviewed by management and began allocating the results of hedging activity associated with managing risks of our refineries, previously reported in corporate, other and eliminations, to our refining segment. The historical results of this hedging activity have been reclassified to conform to the current presentation. The assets and/or liabilities associated with this hedging activity have not been allocated to the refining segment.
