15. Revenues, Product and Geographic Information

Operating segments are defined as components of an enterprise about which separate financial information is available and evaluated regularly by the chief operating decision maker (CODM) in deciding how to allocate resources and in assessing performance. The Company's CODM is its Chief Executive Officer (CEO).

The Company and its consolidated subsidiaries operate in a single segment, defined as a manufacturer of high-technology microfabrication and related equipment. This segment sells products into a variety of end markets that are grouped into four major categories for the purpose of providing an understanding of the principal end markets for the products manufactured by the Company, specifically: (1) Printed Circuit Board (PCB), (2) Component Test, (3) Semiconductor, and (4) Industrial Machining. Service sales are interrelated with all major end markets of the Company and are separately presented.
