Segment Reporting [Abstract]  
SEGMENT INFORMATION
SEGMENT INFORMATION

Our segments represent strategic business units that offer different services and products. We evaluate the performance of each segment based on its respective operating income, before general and administrative expenses and certain non-segmental depreciation and amortization expense. General and administrative expenses are not allocated to the operating segments since those expenses relate primarily to the overall management at the entity level. Our principal operations include transportation of petroleum products and anhydrous ammonia, the terminalling and storage of petroleum products and the marketing of petroleum products. Intersegment revenues result from storage agreements with wholly owned subsidiaries of NuStar Energy at lease rates consistent with rates charged to third parties for storage. Related party revenues mainly result from storage agreements with our joint ventures.
Results of operations for the reportable segments were as follows:
