Segment Reporting [Abstract]

OPERATIONS BY GEOGRAPHIC AREAS

OPERATIONS BY GEOGRAPHIC AREAS

We report our offshore contract drilling operation as a single reportable segment: Offshore Contract Drilling Services. The consolidation of our offshore contract drilling operations into one reportable segment is attributable to how we manage our business, including the nature of services provided and the type of customers of such services and the fact that all of our drilling fleet are dependent upon and able to service the worldwide oil industry. The mobile offshore drilling units and related equipment comprising our offshore rig fleet operate in a single, global market for contract drilling services and are often redeployed globally due to changing demands of our customers, which consist largely of major integrated oil and natural gas companies and independent oil and natural gas companies. Our offshore contract drilling services segment currently conducts offshore contract drilling operations located in the U.S. Gulf of Mexico, the Mediterranean Sea, offshore West Africa, offshore Southeast Asia and offshore Australia.

The accounting policies of our reportable segment are the same as those described in the summary of significant accounting policies (see Note 2). We evaluate the performance of our operating segment based on revenues from external customers and segment profit. A summary of revenues for the fiscal years ended September 30, 2012, 2011 and 2010 and long-lived assets by geographic areas as of September 30, 2012, 2011 and 2010 is as follows (in thousands):
