Segment Reporting

Our Chief Operating Decision Makers (CODMs), which consist of the Chief Executive Officer and the President, review our consolidated results within one operating segment. In making operating decisions, our CODMs primarily consider consolidated financial information accompanied by disaggregated revenue information by geographic region. We eliminate all intercompany revenues in computing revenues by geographic regions. Revenues related to operations in the geographic regions were as follows:
