Segment Reporting [Abstract] |
Schedule of Operating Performance and Assets by Segment | Our CODM allocates resources and evaluates business performance based on revenues and net income (loss). Net income (loss) is used in the annual budgeting and monthly forecasting processes and to monitor and assess budgeted/forecasted versus actual results. Our CODM does not evaluate segments using asset information. The accounting policies for segments are the same as those described in the summary of significant accounting policies. The following tables present selected financial information with respect to segments for the periods presented:
