World Wide Aerospace is a designer and manufacturer of products utilized in a variety of aerospace applications. It supplies product to both military and commercial customers. On the military side the U.S. government is the primary customer with approximately 15% of its military sales going to foreign governments as either spares for U.S. designed aircraft or in an OEM (original equipment manufacturer) capacity. Other military customers include The Boeing Company, Lockheed Martin, Pratt and Whitney, Bell Helicopter and Rolls Royce. Commercial customers include The Boeing Company, United Technologies members and a number of foreign customers in Europe and BRIC countries. Sales to these customers account for approximately 45% of the total revenue. The nature of the business is low volume and high mix including mature and maturing products as well as new product designs for both markets (military and commercial) which makes up 21% of total revenue. For most products, product sales, development and lead times are long.
