Segment Information |
Segment Information | 12. Segment Information ​ We have determined that we operate in three identifiable industry segments: (a) security and inspection systems (Security division), (b) medical monitoring systems (Healthcare division) and (c) optoelectronic devices and manufacturing (Optoelectronics and Manufacturing division). We also have a corporate segment (Corporate) that includes executive compensation and certain other general and administrative expenses, expenses related to stock issuances and legal, audit and other professional service fees not allocated to industry segments. Both the Security and Healthcare divisions comprise primarily end-product businesses, whereas the Optoelectronics and Manufacturing division primarily supplies components and subsystems to external OEM customers, as well as to the Security and Healthcare divisions. Sales between divisions are at transfer prices that approximate market values. All other accounting policies for the segments are the same as described in Note 1, Basis of Presentation. ​ The following tables present our results of operations and identifiable assets by industry segment (in thousands): ​
