Capital Transactions |
Capital Transactions | (9) Capital Transactions Preferred Stock The Company is authorized to issue 5,000,000 shares of preferred stock in one or more series without shareholder approval. No shares of preferred stock are presently outstanding. The Company’s Board of Directors is authorized, without any further action by the shareholders of the Company, to (i) divide the preferred stock into series; (ii) designate each such series; (iii) fix and determine dividend rights; (iv) determine the price, terms and conditions on which shares of preferred stock may be redeemed; (v) determine the amount payable to holders of preferred stock in the event of voluntary or involuntary liquidation; (vi) determine any sinking fund provisions; and (vii) establish any conversion privileges. Stock Compensation On May 4, 2010, the Company’s shareholders approved the adoption of the SkyWest, Inc. 2010 Long‑Term Incentive Plan, which provides for the issuance of up to 5,150,000 shares of common stock to the Company’s directors, employees, consultants and advisors (the “2010 Incentive Plan”). The 2010 Incentive Plan provides for awards in the form of options to acquire shares of common stock, stock appreciation rights, restricted stock grants, restricted stock units and performance awards. The 2010 Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”), which is authorized to designate option grants as either incentive stock options for income tax purposes (“ISO”) or non-statutory stock options ISOs are granted at not less than 100% of the market value of the underlying common stock on the date of grant. Non‑statutory stock options are granted at a price as determined by the Compensation Committee. The fair value of stock options awarded under the Company’s stock option plans has been estimated as of the grant date using the Black‑Scholes option pricing model. The Company uses historical data to estimate option exercises and employee termination in the option pricing model. The expected term of options granted is derived from the output of the option pricing model and represents the period of time that options granted are expected to be outstanding. The expected volatilities are based on the historical volatility of the Company’s traded stock and other factors. The Company granted 206,021, 267,433 and 255,503 stock options to employees under the 2010 Incentive Plan during the years ended December 31, 2016, 2015 and 2014, respectively. Stock options granted in 2015 and 2016 vest in three equal installments over a three-year period. Stock options granted in 2014 have three-year cliff vesting periods. The following table shows the assumptions used and weighted average fair value for grants in the years ended December 31, 2016, 2015 and 2014.

The Company recorded share‑based compensation expense only for those options that are expected to vest. The estimated fair value of the stock options is amortized over the vesting period of the respective stock option grants. During the year ended December 31, 2016, the Company granted 380,358 restricted stock units to certain of the Company’s employees under the 2010 Incentive Plan. The restricted stock units granted during the year ended December 31, 2016 have a three‑year cliff-vesting period, during which the recipient must remain employed with the Company or its subsidiaries. The weighted average fair value of the restricted stock units at the date of grants made during the year ended December 31, 2016 was $14.81 per share. The following table summarizes the activity of restricted stock units granted to certain Company employees as of December 31, 2016, 2015 and 2014:

During the year ended December 31, 2016, the Compensation Committee granted performance share units, which are performance based restricted stock units, to certain Company employees with three-year performance based financial metrics that the Company must meet before those awards may be earned and the performance period for those grants ends December 31, 2018. The Compensation Committee will determine the achievement of performance results and corresponding vesting of performance shares for each performance period. At the end of each performance period, the number of shares awarded can range from 0% to 150% of the original granted amount, depending on the performance against the pre-established targets. The following table summarizes the activity of performance share units granted at target as of December 31, 2016.

During the year ended December 31, 2016, 2015 and 2014, the Company recorded equity‑based compensation expense of $7.6 million, $5.4 million and $5.3 million, respectively. As of December 31, 2016, the Company had $9.7 million of total unrecognized compensation cost related to non‑vested stock options, non‑vested restricted stock grants and non-vested performance stock units. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. The Company expects to recognize this cost over a weighted average period of 1.7 years. Options are exercisable for a period as defined by the Compensation Committee on the date granted; however, no stock option will be exercisable before six months have elapsed from the date it is granted and no stock option shall be exercisable after seven years from the date of grant.
