12. GEOGRAPHIC INFORMATION AND MAJOR CLIENTS

Geographic Information

Operating segments are defined as components of an enterprise, about which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance.

The Company develops and licenses software applications for customer engagement and its Pega^® Platform, and provides consulting services, maintenance, and training related to its offerings. The Company derives substantially all of its revenue from the sale and support of one group of similar products and services—software that provides case management, business process management, and real-time decisioning solutions to improve customer engagement and operational excellence in the enterprise applications market. To assess performance, the Company’s CODM, who is the chief executive officer, reviews financial information on a consolidated basis. Therefore, the Company determined it has one reportable segment—Customer Engagement Solutions and one reporting unit.

The Company’s international revenue, based upon the clients’ location, is as follows:
