BUSINESS SEGMENT

Operating segments are defined as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. We have one operating and reporting segment, OrthoPediatrics, which designs, develops and markets anatomically appropriate implants and devices for children with orthopedic problems. Our chief operating decision-maker, our Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance, accompanied by disaggregated revenue information by product category. We do not assess the performance of our individual product categories on measures of profit or loss, or other asset-based metrics. Therefore, the information below is presented only for revenue by category and geography.
