(a)
The Company accounts for its investment in EFS Midstream LLC ("EFS Midstream") using the equity method. EFS Midstream is providing gathering, treating and transportation services for the Company during a 20-year contractual term.

Loss from vertical integration services primarily represents net margins that result from Company-provided fracture stimulation and related service operations, which are ancillary to and supportive of the Company's oil and gas joint operating activities, and do not represent intercompany transactions. For the three months ended March 31, 2015, these vertical integration net margins included $112 million of revenues and $112 million of costs and expenses. For the same period in 2014, these vertical integration net margins included $92 million of revenues and $94 million of costs and expenses.
