We are a leader in healthcare staffing with a primary focus on providing nurse and allied and physician (locum tenens) staffing services and workforce solutions to the healthcare market. We believe we are one of the top two providers of nurse and allied staffing services, one of the top four providers of temporary physician staffing (locum tenens) services, and one of the top five providers of retained physician and healthcare executive search services. We report our financial results according to three business segments: (1) nurse and allied staffing, (2) physician staffing, and (3) other human capital management services. In February 2013, we sold our clinical trial services business.
On a company-wide basis, we have approximately 4,000 contracts with hospitals and healthcare facilities, and other healthcare organizations to provide our staffing services and workforce solutions. No single client accounts for more than 4% of our revenue. Our fees are paid directly by our clients and in certain cases by third-party vendor managers. As a result, we have no direct exposure to Medicare or Medicaid reimbursements.
