Segment Information

13. Segment Information:

     

While we only have operations in the oil and gas exploration and production industry, we are organizationally structured along geographic operating segments. Our current operating segments are the United States, Malaysia, China and Other International. The accounting policies of each of our operating segments are the same as those described in Note 1, “Organization and Summary of Significant Accounting Policies.”

     

The following tables provide the geographic operating segment information for the three and nine months ended September 30, 2011 and 2010. Income tax allocations have been determined based on statutory rates in the applicable geographic segment.
