Southwestern Energy Company (Southwestern) is an independent energy company primarily focused on the exploration and production of natural gas within the United States. Its operations primarily are located in Arkansas, Oklahoma, Pennsylvania and Texas. The Company also focuses on creating and capturing additional value through its natural gas gathering and marketing businesses, which it refers to as its Midstream Services. Effective July 1, 2008, the Company sold its utility subsidiary, Arkansas Western Gas Company (AWG) and, as a result, the Company does not have any natural gas distribution operations. During the year ended December 31, 2008, the Company sold the oil and gas leases, wells and equipment that consist of its Permian Basin and onshore Texas Gulf Coast operating assets. In 2008, it also sold certain oil and gas leases, wells and gathering equipment in its Fayetteville Shale play to XTO Energy, Inc.
