Segment Information

(14) 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) and the south Louisiana processing and NGL assets (PNGL). Segment data for the years ended December 31, 2011, 2010 and 2009 do not include assets held for sale. The Partnership's 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 principally of property and equipment, including software, for general corporate support, working capital, debt financing costs and its investment in HEP. Profit in the corporate segment for the years ended 2010 and 2009 includes the operating activity of assets sold but not considered discontinued operations as well as intersegment eliminations.

 

Summarized financial information concerning the Partnership's reportable segments as consolidated into the Company's financial statements is shown in the following table.
