Stock-based Compensation The Company's 2014 Omnibus Incentive Plan (the "2014 Incentive Plan") provides grants of stock options, stock appreciation rights, restricted stock, other stock-based awards and other cash-based awards. Directors, officers and other employees of the Company and its subsidiaries, as well as others performing consulting or advisory services for the Company, are eligible for grants under the 2014 Incentive Plan. The purpose of the 2014 Incentive Plan is to provide incentives that will attract, retain and motivate high performing officers, directors, employees and consultants by providing them with appropriate incentives and rewards either through a proprietary interest in our long-term success or compensation based on their performance in fulfilling their personal responsibilities. The aggregate number of shares of common stock which may be issued or used for reference purposes under the 2014 Incentive Plan or with respect to which awards may be granted may not exceed 12,000,000 shares. As of June 30, 2018 , 1,827,600 shares were available for grant. Options granted prior to 2016 vested immediately. Options granted beginning in 2016 generally vest 50% after three years and 50% after four years, with the exception of approximately 1.2 million options issued in 2018 that vest 25% each year over four years. The options have an exercise price of between $6.31 and $10.62 per share. The expected term of each option grant was calculated using the simplified method, defined as the midpoint between the vesting period and the contractual term of each award. The expected volatility was based on market conditions of the Company and comparable companies. The risk-free interest rate was based on the U.S. Treasury yield curve in effect on the date of grant which most closely corresponds to the expected term of the option. The Company historically had not paid dividends and therefore did not utilize a dividend yield in the calculations, however, beginning with grants made in 2018, we have used an annual dividend of $0.30 per share in our calculations. The following table summarizes stock option activity for the six months ended June 30, 2018 : Shares Weighted Average Weighted Average Aggregate Intrinsic Value Outstanding at January 1, 2018 8,544,225 $ 9.50 6.11 $ — Granted 1,342,000 6.38 Exercised — — Forfeited (174,940 ) 9.36 Outstanding at June 30, 2018 9,711,285 $ 9.07 6.13 $ 203,200 Stock-based compensation expense was $0.2 million and $0.3 million for the three months ended June 30, 2017 and 2018, respectively, and $0.4 million and $ 0.4 million for the six months ended June 30, 2017 and 2018, respectively. As of June 30, 2018 , total unrecognized stock-based compensation expense is $7.2 million , including $2.6 million related to restricted stock awards, to be recognized over four or five years. On May 31, 2018, the Company issued 400,000 shares of restricted stock under the 2014 incentive plan, none of which were vested as of June 30, 2018.
