21. Major Customers and Segment Information
Sales to ExxonMobil Corporation and Plains Marketing, L.P. constituted approximately 12% and 11%, respectively,
of our total revenues (before the effects of hedging) for the years ended December 31, 2014 and 2012, respectively.
There were no sales to individual customers constituting 10% or more of total revenues (before the effects of hedging)
for the year ended December 31, 2013.
As of December 31, 2014, we have two reportable operating segments, each of which is managed separately
because of the nature of its operations. The exploration and production operating segment is responsible for finding
and producing oil, natural gas and NGL. The marketing, gathering and compression operating segment is responsible
for marketing, gathering and compression of oil, natural gas and NGL. In addition, prior to the spin-off described in
Note 13, our former oilfield services operating segment was responsible for drilling, oilfield trucking, oilfield rentals,
hydraulic fracturing and other oilfield services operations for both Chesapeake-operated wells and wells operated by
third parties. Our former oilfield services segment’s historical financial results for periods prior to the spin-off continue
to be included in our historical financial results as a component of continuing operations, as reflected in the table below.
Management evaluates the performance of our segments based upon income (loss) before income taxes.
Revenues from the sale of oil, natural gas and NGL related to Chesapeake’s ownership interests by our marketing,
gathering and compression operating segment are reflected as revenues within our exploration and production
operating segment. These amounts totaled $8.565 billion, $7.570 billion and $5.464 billion for the years ended
December 31, 2014, 2013 and 2012, respectively. Revenues generated by our former oilfield services operating
segment for work performed for Chesapeake’s exploration and production operating segment were reclassified to the
full cost pool based on Chesapeake’s ownership interest. Revenues reclassified totaled $544 million, $1.309 billion
and $1.315 billion for the years ended December 31, 2014, 2013 and 2012, respectively. No income was recognized
in our consolidated statements of operations related to oilfield services performed for Chesapeake-operated wells.
