14. STOCK-BASED COMPENSATION PLANS

ÌýÌýÌýÌýÌýÌýÌýÌýOn MayÌý5, 2016, our stockholders approved a new ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Corporation 2016 Stock Incentive Plan (the "2016 Stock Incentive Plan"), which reserved 8.2Ìýmillion shares for issuance. The ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Corporation Stock Incentive Plan, as amended and restated (the "Prior Plan"), remains in effect for outstanding awards granted pursuant to the Prior Plan, but no further awards may be granted under the Prior Plan. Under the 2016 Stock Incentive Plan we may grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, phantom stock, performance share units and other stock-based awards to our employees, directors and consultants and to employees and consultants of our subsidiaries, provided that incentive stock options may be granted solely to employees. The terms of the grants under both the 2016 Stock Incentive Plan and the Prior Plan are fixed at the grant date. As of JuneÌý30, 2016, we were authorized to grant up to 8.2Ìýmillion shares under the 2016 Stock Incentive Plan. As of JuneÌý30, 2016, we had approximately 8Ìýmillion shares remaining under the 2016 Stock Incentive Plan available for grant. Option awards have a maximum contractual term of 10Ìýyears and generally must have an exercise price at least equal to the market price of our common stock on the date the option award is granted. Outstanding stock-based awards generally vest over a three-year period; certain performance share unit awards vest over a two-year period.

STOCK OPTIONS

ÌýÌýÌýÌýÌýÌýÌýÌýThe fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatility of our common stock through the grant date. The expected term of options granted was estimated based on the contractual term of the instruments and employees' expected exercise and post-vesting employment termination behavior. The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions noted below represent the weighted average of the assumptions utilized for stock options granted during the periods.

ÌýÌýÌýÌýÌýÌýÌýÌýThe weighted-average grant-date fair value of stock options granted during the six months ended JuneÌý30, 2016 was $2.97 per option. As of JuneÌý30, 2016, there was $14Ìýmillion of total unrecognized compensation cost related to nonvested stock option arrangements granted under the 2016 Stock Incentive Plan and the Prior Plan. That cost is expected to be recognized over a weighted-average period of approximately 2.1Ìýyears.

ÌýÌýÌýÌýÌýÌýÌýÌýThe total intrinsic value of stock options exercised during the six months ended both JuneÌý30, 2016 and 2015 was approximately nil.

NONVESTED SHARES

ÌýÌýÌýÌýÌýÌýÌýÌýNonvested shares granted under the 2016 Stock Incentive Plan and the Prior Plan consist of restricted stock and performance share unit awards, which are accounted for as equity awards, and phantom stock, which is accounted for as a liability award because it can be settled in either stock or cash.

ÌýÌýÌýÌýÌýÌýÌýÌýThe fair value of each performance share unit award is estimated using a Monte Carlo simulation model that uses various assumptions, including an expected volatility rate and a risk-free interest rate. For the six months ended JuneÌý30, 2016 and 2015, the weighted-average expected volatility rate was 39.3% and 30.0%, respectively and the weighted average risk-free interest rate was 0.9% and 0.7%, respectively. For the performance share unit awards granted in the six months ended JuneÌý30, 2016 and 2015 the number of shares earned varies based upon the Company achieving certain performance criteria over two-year and three-year performance periods. The performance criteria are total stockholder return of our common stock relative to the total stockholder return of a specified industry peer group for the two-year and three-year performance periods.
