INDUSTRY SEGMENTS AND GEOGRAPHIC AREAS
NOTE 16 - INDUSTRY SEGMENTS AND GEOGRAPHIC AREAS

Occidental conducts its operations through three segments: (1) oil and gas; (2) chemical; and (3) midstream and marketing. The factors used to identify these segments are based on the nature of the operations that are undertaken in each segment. Income taxes, interest income, interest expense, environmental remediation expenses, Anadarko Acquisition-related costs and unallocated corporate expenses are included under corporate and eliminations. Intersegment sales eliminate upon consolidation and are generally made at prices approximating those that the selling entity would be able to obtain in third-party transactions. Identifiable assets are those assets used in the operations of the segments. Corporate assets consist of cash and restricted cash, certain corporate receivables and PP&E. The chief operating decision maker analyzes each segment’s operating results to make decisions about resources to be allocated to the segment and to assess its performance as well as Occidental’s overall performance.
