(*) The fair value of the options granted during the six months period ended June 30, 2017 was estimated by using a Black-Scholes option-pricing model which requires the following assumptions: risk-free interest rates of 1.6% - 1. 9% which is based on the yield from U.S. treasury zero-coupon bonds with an equivalent term to the options' expected term, expected volatility of 49.3% - 55.9% which is calculated based upon actual historical stock price movements over the most recent periods ending on the grant date and an expected term of 3.45 - 4.76 years which is generated by running a Monte Carlo model pursuant to which historical post-vesting forfeitures and suboptimal exercise factor are estimated by using historical option exercise information of the options.
