We manage our business as two Our EMS segment sells its products to semiconductor manufacturers and third third May 2017, Both of our operating segments have multiple products that we design, manufacture and market to our customers. Due to a number of factors, our products have varying levels of gross margin. The mix of products we sell in any period is ultimately determined by our customers' needs.

As a result, our consolidated gross margin can be significantly impacted in any given period by a change in the mix of products sold in that period. Historically, we have referred to our markets as “Semiconductor” (which includes both the broader semiconductor market as well as the more specialized ATE and wafer processing sectors within the broader semiconductor market), and “Non-Semiconductor” (which includes all of the other markets we serve).
