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 Corp., 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 disaggregate revenue from contracts with customers by operating segment. We determined that disaggregating revenue into these categories achieves the disclosure objective of illustrating the differences in the nature, timing and uncertainty of our revenue streams. 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.
