[1] Revenue by geographic region disclosed above is net of any inter-segment revenue and, therefore, represents only revenue from external customers according to the location of the operating subsidiary.

[2] Direct costs in Temporary Contracting include the direct staffing costs of salaries, payroll taxes, employee benefits, travel expenses, rent and insurance costs for the Company’s contractors and reimbursed out-of-pocket expenses and other direct costs. Other than reimbursed out-of-pocket expenses, there are no other direct costs associated with the Permanent Recruitment and Other category. Gross margin represents revenue less direct costs. The region where services are provided, the mix of contracting and permanent recruitment, and the functional nature of the staffing services provided can affect gross margin. The salaries, commissions, payroll taxes and employee benefits related to recruitment professionals are included under the caption "Selling, general and administrative expenses" in the Condensed Consolidated Statements of Operations and Other Comprehensive Income (Loss).
