Our LaserAlign sensor family has historically accounted for a significant portion of our sales and profitability.  Our revenue, results of operations and cash flows would be negatively impacted if our LaserAlign customers, primarily Juki and Assembleon, are unsuccessful selling the products into which our sensors are incorporated, design their products to function without our sensors, purchase sensors from other suppliers, or otherwise terminate their relationships with us.

We are dependent upon three customers, Juki, Assembleon, and LaserTek, a distributor of our inspection systems in China, for a significant portion of our total revenue.  For the nine months ended September 30, 2012, sales to Juki accounted for 13% of our total revenue, sales to Assembleon accounted for 13% of our total revenue and sales to LaserTek accounted for 11% of our total revenue.
