Segment Reporting [Abstract]

Segment Information

Segment Information

Identification of operating segments is based principally upon regions served.  The Partnership’s reportable segments consist of the natural gas gathering, processing and transmission operations located in north Texas and in the Permian Basin in west Texas ("NTX"), the pipelines and processing plants located in Louisiana ("LIG"), the south Louisiana processing and NGL assets ("PNGL") and rail, truck, pipeline, and barge facilities in the ORV, which includes the Company's investment in E2. Operating activity for intersegment eliminations is shown in the corporate segment.  Sales are derived from external domestic customers.

The Partnership evaluates the performance of its operating segments based on operating revenues and segment profits. Corporate expenses include general partnership expenses associated with managing all reportable operating segments. Corporate assets consist primarily of property and equipment, including software, for general corporate support, working capital, debt financing costs and its investment in Howard Energy Partners ("HEP").

Summarized financial information concerning reportable segments is shown in the following table.
