Equity | Note 8 - Equity A. Stock option plans During the three months ended March 31, 2017 and March 31, 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 those options are $1.58. Those options expire up to five years after the date of the 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 three months ended March 31, 2017 and March 31, 2016, for which the exercise price was greater than par value, 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 three months ended March 31, 2017 and March 31, 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 three months ended March 31, 2017 and March 31, 2016, respectively, using the simplified method. 4. Expected average volatility of 74% and 72% for grants during the three months ended March 31, 2017 and March 31, 2016, respectively, which represent a weighted average standard deviation rate for the price of the Company's Ordinary Shares on the NASDAQ Capital Market. The Company’s options activity (including options to non-employees) and options outstanding and options exercisable as of December 31, 2016 and March 31, 2017, are summarized in the following table: Weighted Number of options average exercise price outstanding per share Outstanding -December 31, 2016 1,604,836 $ 1.36 Options granted 100,000 1.58 Options expired or forfeited (180,667 ) 2.26 Options exercised (1,668 ) 0.74 Outstanding -March 31, 2017 1,522,501 1.27 Exercisable as of: December 31, 2016 591,017 $ 1.83 March 31, 2017 513,014 $ 1.52 The weighted average fair value of options granted during the three months ended March 31, 2017 and during the three months ended March 31, 2016 is $0.93 and $0.41, respectively, per option.
