| Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description | Segment operating income is the measure utilized by the CODM to assess performance and allocate resources. When evaluating the Company’s financial performance, the CODM regularly reviews revenues, compensation and benefits, reimbursable expenses and other segment items. Compensation costs are key metrics reviewed by the CODM when allocating resources and assessing performance as the Company depends significantly on human capital to deliver services to its clients. The CODM uses segment operating (loss) income as the profit measure in evaluating segment performance during the annual planning and forecasting process and in monitoring actual performance versus plan. | ||
