Stock-Based Compensation Plans |
10. Stock-Based Compensation Plans Stock-Based Compensation Expense The Company measures compensation cost related to stock options based on the grant-date fair value of the awards, calculated using the Black-Scholes option-pricing model. The compensation cost related to time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) is based on the market price of the stock on the date of the award. The fair values of the stock options and RSUs are recognized ratably over their respective vesting periods. The fair values of PSUs are recognized when it is probable that the performance conditions will be achieved.
In 2017, Nexstar issued 228,438 replacement stock options in connection with its acquisition of Media General (See Note 3). There were no stock options granted in 2018 and 2016. The assumptions used in calculating the fair values of options granted during the year ended December 31, 2017 was as follows:
The expected volatility assumptions used for stock option grants were based on Nexstar’s historical volatility rates over a period approximating the expected life of the options. The expected term assumption is calculated utilizing Nexstar’s historical exercise and post-vesting cancellation experience combined with expectations developed over outstanding options. The risk-free interest rates used are based on the daily U.S. Treasury yield curve rate in effect at the time of the grant having a period commensurate with the expected term assumption. The expected dividend yield is based on the current annual dividend divided by the stock price on the date of grant. The Company recognized stock-based compensation expense of $31.3 million, $24.1 million and $11.4 million for the years ended December 31, 2018, 2017 and 2016, respectively. As of December 31, 2018, there was $65.1 million of total unrecognized compensation cost related to stock options and restricted stock units, expected to be recognized over a weighted-average period of 2.43 years. Stock-Based Compensation Plans Nexstar has two stock-based compensation plans that provide for the granting of stock options, stock appreciation rights, RSUs and PSUs to directors, employees or consultants of Nexstar: the 2015 Long-Term Equity Incentive Plan, approved by Nexstar’s majority stockholders on June 11, 2015 (the “2015 Plan”) and the 2012 Long-Term Equity Incentive Plan, approved by Nexstar’s majority stockholders on September 26, 2012 (the “2012 Plan”). A maximum of 2,500,000 shares and 1,500,000 shares of Nexstar’s Class A common stock can be issued under the 2015 Plan and the 2012 Plan, respectively. No new awards are granted under equity incentive plans prior to these plans but any unissued available shares can be issued under the 2012 Plan. At December 31, 2018, 853,813 shares remained available for future grants, of which 836,063 shares and 17,750 shares were available under the 2015 Plan and the 2012 Plan, respectively. Nexstar utilizes any available treasury stock or issues new shares of its Class A common stock when options are exercised or restricted stock units vest. Stock Options Options are granted with an exercise price at least equal to the fair market value of the underlying shares of common stock on the date of the grant, vest over a range of four to five years and expire ten years from the date of grant. Except as otherwise determined by the compensation committee or with respect to the termination of a participant’s services in certain circumstances, including a change of control, no option may be exercised within six months of the date of the grant. Upon the employee’s termination, all nonvested options are forfeited immediately and any unexercised vested options are cancelled from 30 to 180 days following the termination date. The following table summarizes activity and information related to stock options for the year ended December 31, 2018:
Aggregate intrinsic value represents the difference between the closing market price of Nexstar’s common stock on the last day of the fiscal period, which was $78.64 on December 31, 2018, and the stock option exercise prices multiplied by the number of options outstanding. For the years ended December 31, 2018, 2017 and 2016, the aggregate intrinsic value of options exercised, on their respective exercise dates, was $5.0 million, $34.1 million and $2.3 million, respectively. For the years ended December 31, 2018, 2017 and 2016, the aggregate fair value of options vested was $6.6 million, $17.6 million and $9.0 million, respectively.
Time-Based Restricted Stock Units The RSUs vest over a range of two to five years from the date of the award. All unvested RSUs are forfeited immediately upon the employee’s termination for any reason other than change of control. The following table summarizes activity and information related to RSUs for the year ended December 31, 2018:
Performance-Based Restricted Stock Units The vesting of the PSUs is contingent on the continued service of the grantee and the achievement of specific performance metrics (generally over a three-year period) designated by the Board of Directors of the Company. All unvested PSUs are forfeited immediately upon the employee’s termination for any reason other than change of control. The following table summarizes activity and information related to PSUs for the year ended December 31, 2018:
