Equity | Note 8 - Equity A. Stock option plans During the six months ended June 30, 2017 and June 30, 2016, 100,000 and 270,000 options were granted, respectively. The vesting period for the options ranges from three years to four years. The exercise prices for the options range from $0.44 to $1.58. Those options expire up to five years after the date of grant. Any options which are forfeited or cancelled before expiration become available for future grants under the Company’s option plan. The fair value of each option granted to employees and non-employees during the six months ended June 30, 2017 and June 30, 2016, was estimated on the date of grant, using the Black-Scholes model and the following assumptions: 1. Dividend yield of zero percent for all periods. 2. Risk-free interest rate of 1.35% and 1.18% for grants during the six months ended June 30, 2017 and June 30, 2016, respectively, based on U.S. Treasury yield curve in effect at the time of grant. 3. Estimated expected lives of 3.50 and 3.56 years for grants during the six months ended June 30, 2017 and June 30, 2016, respectively, using the simplified method. 4. Expected average volatility of 74% and 72% for grants during the six months ended June 30, 2017 and June 30, 2016, respectively, which represent a weighted average standard deviation rate for the price of the Company's Ordinary Shares on the NASDAQ Capital Market.
