Employee Stock Purchase Plan

The Company’s 2000 Employee Stock Purchase Plan (the “ESPP”) permits eligible employees to purchase newly issued shares of the Company's common stock, at a price equal to 85% of the lower of the fair market value on (i) the first day of the offering period or (ii) the last day of each six-month purchase period, through payroll deductions of up to 10% of their annual cash compensation.

The Company terminated the ESPP in 2012 but reinstated the program effective August 16, 2014. Under the reinstated ESPP, the Company is authorized to issue 1,500,132 shares of common stock purchased by eligible employees under the plan.

During the three and nine months ended September 30, 2015, the Company recognized $0.1 million and $0.3 million, respectively, of stock-based compensation expense related to the ESPP. During each of the three and nine months ended September 30, 2014, the Company recognized approximately $26,000 of stock-based compensation expense related to the ESPP.
