On June 15, 2016, at the Company's 2016 Annual Meeting of Stockholders, the stockholders of the Company approved the 2016 Equity and Incentive Plan (2016 Plan). The 2016 Plan authorizes the Company to issue up to 3,000 shares of common stock (plus an additional 1,690 shares intended to roll over into the 2016 Plan shares subject to awards outstanding on June 15, 2016 under earlier plans that may be forfeited, canceled, reacquired by the Company or terminated) pursuant to stock options, restricted stock awards and other stock-based awards. The Company granted 40 and 419 restricted stock awards, subject to the terms of the 2016 Plan or the Amended and Restated 2006 Stock Incentive Plan (2006 Plan), as applicable, to employees during the three and nine months ended September 30, 2016, respectively, and 40 and 203 restricted stock awards, subject to the terms of the 2006 Plan, to employees during the three and nine months ended September 30, 2015, respectively. The Company granted 0 and 60 stock options to employees under the terms of the Amended and Restated 2006 Stock Incentive Plan during the three and nine months ended September 30, 2016, respectively, and 0 and 95 stock options during the three and nine months ended September 30, 2015, respectively.

As amended, the ESPP affords eligible employees the right to purchase common stock, via payroll deductions, through various offering periods at a purchase price equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. The Company recorded compensation charges of $0 and $14 for the three months ended September 30, 2016 and 2015, respectively, and $0 and $43 for the nine months ended September 30, 2016 and 2015, respectively, related to the ESPP.
