Operating Segments, Geographic Analysis and Major Customers |
Operating Segments, Geographic Analysis and Major Customers | Note 23—Operating Segments, Geographic Analysis and Major Customers Operating segments—We have established two operating segments: (1) contract drilling services and (2) drilling management services. Our contract drilling services business operates in a single, global market for the provision of contract drilling services. The location of our rigs and the allocation of our resources to build or upgrade rigs are determined by the activities and needs of our customers. Our drilling management services operating segment does not meet the quantitative thresholds for determining reportable segments. Geographic analysis—Operating revenues for our continuing operations by country were as follows (in millions):

(a) Other countries represents countries in which we operate that individually had long-lived assets representing less than 10 percent of total long-lived assets. A substantial portion of our assets are mobile. Asset locations at the end of the period are not necessarily indicative of the geographic distribution of the revenues generated by such assets during the periods. Although we are organized under the laws of Switzerland, we do not conduct any operations and do not have operating revenues in Switzerland. At December 31, 2013 and 2012, the aggregate carrying amount of our long-lived assets located in Switzerland was $6 million and $7 million, respectively. Our international operations are subject to certain political and other uncertainties, including risks of war and civil disturbances or other market disrupting events, expropriation of equipment, repatriation of income or capital, taxation policies, and the general hazards associated with certain areas in which we operate. Major customers—For the year ended December 31, 2013, Chevron Corporation and BP accounted for approximately 12 percent and 10 percent, respectively, of our consolidated operating revenues from continuing operations. For the year ended December 31, 2012, Chevron Corporation, BP and Petrobras accounted for approximately 11 percent, 11 percent and 10 percent, respectively, of our consolidated operating revenues from continuing operations.
