Stock-Based Compensation | Stockholder's Equity (a) Stock Equity and Incentive Plan The Company adopted ASC Update No. 2016-09, Compensation- Stock Compensation (ASC Topic 718): Improvements to Employee Share-Based Payment Accounting on January 1, 2017. Although, this ASC update did not impact the Company’s results of operations, financial position or cash flows for any periods prior to the adoption, the adoption of this ASC update had the following impact on the date of adoption: • The adoption of ASC Update No. 2016-09 requires all income tax adjustments to be recorded in the consolidated statements of operations. The cumulative adjustment upon adoption to accumulated earnings was zero since the increase in net deferred tax assets was fully offset by a corresponding increase in the deferred tax asset valuation allowance. The amount of deferred tax assets that had not been previously recognized due to the recognition of excess tax benefits was $1,571 . • The tax benefit or expense is required to be classified as a cash flow provided by (used in) operating activities. It was previously required to be presented as a cash flow provided by (used in) financing activities in the Consolidated Statements of Cash Flows, with a corresponding adjustment to operating cash flows. • In the diluted net earnings per share calculation, when applying the treasury stock method for shares that could be repurchased, the assumed proceeds no longer include the amount of excess tax benefit. This provision, which is only applicable on a prospective basis, did not have an impact on the Company's diluted net earnings per share calculation for the three and six months ended June 30, 2017 . • The Company has elected to account for forfeitures on share-based payments as these forfeitures occur, which represents a change from the accounting previously required under ASC Topic 718. As a result, future forfeitures could result in a significant reversal of stock-based compensation expense recognized in the period in which such forfeitures occur. During the three and six months ended June 30, 2017 , as a result of share-based award forfeitures, the Company recorded a reversal of previously recognized stock-based compensation expense of $52 and $57 , respectively. In addition, had the Company continued to account for stock-based compensation expense related to forfeitures of share-based payments based on estimating the number of awards expected to be forfeited and recognizing only stock-based compensation expense on awards expected to vest, the Company would have recognized $778 and $ 1,705 of stock-based compensation expense, or $71 and $ 87 less than what was actually recorded, during the three and six months ended June 30, 2017 , respectively. The Company recognizes stock-based compensation in accordance with the provisions of ASC Topic 718, Compensation--Stock Compensation . Stock-based compensation expense, excluding compensation charges related to our employee stock purchase plan, or the ESPP, was $ 849 and $ 841 for the three months ended June 30, 2017 and 2016 , respectively, and $1,792 and $1,881 for the six months ended June 30, 2017 and 2016 , respectively. As of June 30, 2017 , there was $1,794 of total unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted-average period of 3.13 years. As of June 30, 2017 , there was $4,913 of total unrecognized compensation expense related to restricted stock awards, which is expected to be recognized over a weighted-average period of 2.68 years. Stock Options During the three months ended June 30, 2017 , no stock options were exercised for common stock. Additionally, during the three months ended June 30, 2017 , no stock options were granted and 7 stock options were forfeited. During the six months ended June 30, 2017 , 114 stock options were exercised for common stock, none of which was delivered to the Company as payment for the exercise price or related minimum tax withholding obligations. Additionally, during the six months ended June 30, 2017 , 531 stock options were granted with a weighted average grant date fair value of $2.47 per share and 11 stock options were forfeited. The Company has estimated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model. The weighted average assumptions utilized to determine the fair value of options granted during the six months ended June 30, 2017 and 2016 were as follows: Six Months Ended June 30, 2017 2016 Risk-free interest rate 1.96 % 1.43 % Expected volatility 35.53 % 38.22 % Expected life (in years) 4.22 4.17 Dividend yield 0 % 0 % As of June 30, 2017 , there were 1,018 options outstanding with a weighted average exercise price of $9.74 per share and 292 options exercisable with a weighted average exercise price of $12.31 per share. Restricted Stock During the three months ended June 30, 2017 , 14 shares of restricted stock were granted with a weighted average grant date fair value of $9.47 per share and 17 shares of restricted stock were forfeited. Additionally, during the three months ended June 30, 2017 , 10 shares of restricted stock vested, of which no shares of common stock were surrendered to the Company as payment by employees in lieu of cash to satisfy minimum tax withholding obligations in connection with the vesting of restricted stock. During the six months ended June 30, 2017 , 223 shares of restricted stock were granted with a weighted average grant date fair value of $8.39 per share and 17 shares of restricted stock were forfeited. Additionally, during the six months ended June 30, 2017 , 243 shares of restricted stock vested, of which 43 shares of common stock were surrendered to the Company as payment by employees in lieu of cash to satisfy minimum tax withholding obligations in connection with the vesting of restricted stock and these shares were immediately retired. As of June 30, 2017 , there were 607 shares of restricted stock outstanding still subject to service-based vesting conditions. As of June 30, 2017 , the Company had no shares of restricted stock that were subject to performance-based or market-based vesting conditions. (b) Employee Stock Purchase Plan On June 15, 2016, at the Company's 2016 Annual Meeting of Stockholders, the stockholders of the Company approved amendments to the Company's Amended and Restated 1996 Employee Stock Purchase Plan (ESPP) that, among other things, increased the number of shares of common stock reserved for issuance to a total of 1,650 . 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. During the three and six months ended June 30, 2017 , 26 shares were issued under the ESPP plan. During the three and six months ended June 30, 2016, 0 and 18 shares were issued under the ESPP plan, respectively. The Company recorded compensation charges related to the ESPP of $3 and $0 for the three months ended June 30, 2017 and 2016 , respectively, and $20 and $13 for the six months ended June 30, 2017 and 2016 , respectively.
