NOTE 8 STOCK OPTION PLANS Our stock-based employee compensation plans are described below: 2015 Equity Incentive Plan We have a stock awards plan, as amended, (the 2015 Equity Incentive Plan), under which 10,000,000 shares of our authorized but unissued common stock are reserved for issuance to employees, consultants, or to non-employee members of the Board or to any member of the board of directors (or similar governing authority) of any affiliate of the Company. The 2015 Equity Incentive Plan, approved by our shareholders on May 7, 2015, replaced the previously approved stock option plan (the 2005 Equity Incentive Plan). For the 2015 Equity Incentive Plan, the fair value of options was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used for grants in 2017: dividend yield of 0%; volatility of 111%; risk-free interest rate of 1.81%; and expected lives of 5.0 years. The weighted average fair value of options granted was $11.35 per share during 2017. The assumptions for fiscal 2016 are: dividend yield of 0%; volatility of 109%; risk-free interest rate of 1.10%; and expected lives of 5.0 years. The weighted average fair value of options granted was $2.59 per share during 2016. Summarized information for the 2015 Equity Incentive Plan is as follows:
