Reportable Segments PRODUCTS AND SOLUTIONS Our two reportable business segments are Employer Services and Professional Employer Organization (“PEO”). For financial data by segment and by geographic area, see Note 16 to the “Consolidated Financial Statements” contained in this Annual Report on Form 10-K. Employer Services . Our Employer Services segment serves clients ranging from single-employee small businesses to large enterprises with tens of thousands of employees around the world, offering a comprehensive range of technology- based HCM solutions, including our strategic, cloud-based platforms, and HRO (other than PEO) solutions. These solutions address critical client needs and include: Payroll Services, Benefits Administration, Talent Management, HR Management, Workforce Management, Compliance Services, Insurance Services and Retirement Services. Professional Employer Organization . Our PEO business, called ADP TotalSource®, provides clients with comprehensive employment administration outsourcing solutions through a relationship in which employees who work for a client (referred to as “worksite employees”) are co-employed by us and the client. Our reportable segments are based on the way that management reviews the performance of, and makes decisions about, our business. Our strategic pillars represent the strategic growth areas for our business. The results of our business related to products and solutions within the HCM Solutions pillar, the HRO Solutions pillar (other than PEO products and solutions) and the Global Solutions pillar are contained within our Employer Services segment. The results of our business within the HRO Solutions pillar related to our PEO products and solutions are contained within our PEO Segment.
