Employee Stock Purchase Plan

14.Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan for all U.S.-based employees meeting certain eligibility criteria.  Under the Plan, eligible employees may purchase shares of our common stock at 85% of the market value at the beginning of a six-month election period.  Purchases are limited to 10% of an employee's eligible compensation and the shares purchased are restricted from being sold for one year from the purchase date.  At June 30, 2017,  129,552 shares remained available under the Plan.
