Stock-Based Compensation [Abstract] |
Stock-Based Compensation | Note 10—Stock-Based Compensation Stock-Based Compensation Plan The Company’s 2011 Stock Option and Incentive Plan is intended to provide incentives to executives, employees, directors and consultants of the Company. Incentives available under the 2011 Stock Option and Incentive Plan may include stock options, stock appreciation rights, limited rights, deferred stock units, and restricted stock. The plan is administered by the Compensation Committee of the Company’s Board of Directors. On May 5, 2015, the Company’s stockholders approved an amendment and restatement to the Company’s 2011 Stock Option and Incentive Plan that increased the number of shares of the Company’s Class B common stock available for the grant of awards thereunder by an additional 180,000 shares. At December 31, 2015, the Company had 1.3 million shares of Class B common stock reserved for award under its 2011 Stock Option and Incentive Plan and 0.2 million shares were available for future grants. Restricted Stock The fair value of restricted shares of the Company’s Class B common stock is determined based on the closing price of the Company’s Class B common stock on the grant date. Share awards generally vest on a graded basis over three years of service following the grant. A summary of the status of the Company’s grants of restricted shares of Class B common stock is presented below:

The total grant date fair value of shares vested in the years ended December 31, 2015, 2014 and 2013 was $0.5 million, $2.5 million and $3.3 million, respectively.

Stock Options Option awards are generally granted with an exercise price equal to the market price of the Company’s stock on the date of grant. Option awards generally vest on a graded basis over three years of service and have ten-year contractual terms. Expected volatility is based on historical volatility of the Company’s Class B common stock and other factors. The Company uses historical data on exercise of stock options, post vesting forfeitures and other factors to estimate the expected term of the stock-based payments granted. The risk free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options was estimated on the date of the grant using a Black-Scholes valuation model and the assumptions in the following table. No option awards were granted in the year ended December 31, 2014.
