Equity incentive plans

Effective May 16, 2016, the stockholders of all classes of capital stock of the Company approved at the annual stockholder meeting the Hemisphere Media Group, Inc. Amended and Restated 2013 Equity Incentive Plan (the “2013 Equity Incentive Plan”) to increase the number of shares of Class A common stock that may be delivered under the 2013 Equity Incentive Plan to an aggregate of 7.2 million shares of our Class A common stock. At June 30, 2018, 2.6 million shares remained available for issuance of stock options or other stock-based awards under our 2013 Equity Incentive Plan (including shares of restricted Class A common stock surrendered to the Company in payment of taxes required to be withheld in respect of vested shares of restricted Class A common stock, which are available for re-issuance). The expiration date of the 2013 Equity Incentive Plan, on and after which date no awards may be granted, is April 4, 2023. The Company’s board of directors, or a committee thereof, administers the 2013 Equity Incentive Plan and has the sole and plenary authority to, among other things: (i) designate participants; (ii) determine the type, size, and terms and conditions of awards to be granted; and (iii) determine the method by which an award may be settled, exercised, canceled, forfeited or suspended.

The Company’s time-based restricted stock awards and option awards generally vest in three equal annual installments beginning on the first anniversary of the grant date, subject to the grantee’s continued employment or service with the Company. The Company’s event-based restricted stock awards and option awards generally vest upon the Company’s Class A common stock attaining a $15.00 closing price per share, as quoted on the NASDAQ Global Market, on at least 10 trading days, subject to the grantee’s continued employment or service with the Company. Other event-based restricted stock awards granted to certain members of our Board vest on the day preceding the Company’s annual stockholder meeting.

Stock-based compensation

Stock-based compensation expense related to stock options and restricted stock was $1.0 million and $1.1 million for the three months ended June 30, 2018 and 2017, respectively, and $2.0 million and $2.1 million for the six months ended June 30, 2018 and 2017, respectively. At June 30, 2018, there was $1.4 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted-average period of 1.3 years. At June 30, 2018, there was $2.3 million of total unrecognized compensation cost related to unvested restricted stock, which is expected to be recognized over a weighted-average period of 1.2 years.

Stock options

The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option pricing model for time-based options and the Monte Carlo simulation model for event-based options. The expected term of options granted is derived using the simplified method under ASC 718-10-S99-1/SEC Topic 14.D for “plain vanilla” options and the Monte Carlo simulation for event-based options. Expected volatility is based on the historical volatility of the Company’s competitors given its lack of trading history. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The Company has estimated forfeitures of 1.5%, as the awards are granted to management for which the Company expects lower turnover, and has assumed no dividend yield, as dividends have never been paid to stock or option holders and will not be paid for the foreseeable future.

Black-Scholes Option Valuation Assumptions	Six Months Ended June 30, 2018		Year Ended December 31, 2017
Risk-free interest rate	2.7% - 2.8	%	2.2	%
Dividend yield	—		—
Volatility	39.0	%	25.8	%
