Assets Held for Sale

In 2013, we determined we would sell certain of our buildings and land (other than our core campus) in the Oklahoma City area. In addition, as of March 31, 2015, we were continuing to pursue the sale of land located in the Fort Worth, Texas area. Land and buildings are recorded within our other segment. These Oklahoma City and Fort Worth assets are being actively marketed, and we believe it is probable they will be sold over the next 12 months. As a result, these assets are reflected as held for sale as of March 31, 2015. Oil and natural gas properties that we intend to sell are not presented as held for sale pursuant to the rules governing full cost accounting for oil and gas properties. As of March 31, 2015 and December 31, 2014, we had $93 million of buildings and land, net of accumulated depreciation, classified as assets held for sale on our condensed consolidated balance sheets.
