Industry Segment and Geographic Information

We operate in one reportable industry segment: developing and manufacturing products primarily for medical applications and have no foreign operating subsidiaries. We have other product lines which include pressure relief valves and inflation systems, which are sold primarily to the aviation and marine industries. Due to the similarities in product technologies and manufacturing processes, these products are managed as part of our medical products segment. Our revenues from sales to customers outside the United States totaled approximately 37 percent of our net revenues in 2017 and 2016, and 35 percent in 2015. We have no assets located outside the United States.
