Share-Based Compensation | SHARE-BASED COMPENSATION The Company measures and accounts for share-based awards in accordance with ASC 718, Compensation - Stock Compensation. The Company expenses share-based payment awards made to employees and directors, including stock options and restricted stock awards. Share-based compensation expense associated with stock options and restricted stock awards with vesting contingent upon the achievement of service conditions is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period over which the awards are expected to vest. The Company estimates the value of stock options with vesting contingent upon the achievement of service conditions as of the date the award was granted using the Black-Scholes option pricing model, which requires the use of certain input variables, such as expected volatility, risk-free interest rate and expected award life. Share-Based Award Activity During the six months ended June 30, 2018, the Company granted restricted stock awards (“RSAs”) under its 2014 Omnibus Equity Incentive Plan to named executive officers (“NEOs”) and non-employee members of the BOD. The RSAs granted to the NEOs were 100% vested and non-forfeitable on the grant date. The BOD elected to defer up to 100% of their annual retainer fee, chairman fees and meeting fees in the form of common stock. The RSAs granted to the BOD will become fully vested on the earlier of (i) the first anniversary of the date of grant or (ii) the date of the Company's 2019 annual meeting of stockholders. The fair value of the RSAs granted to the NEOs and BOD is recorded as share-based compensation expense on the grant date or over the vesting period, as applicable. The Company withheld 39,228 shares of common stock from NEOs, at a total cost of $0.4 million, to satisfy statutory minimum tax requirements related to the RSAs. A summary of shared-based awards activity during the six months ended June 30, 2018 is as follows:
