Stock Incentive Plans

Under the Co Diagnostics, Inc 2015 Long-term Incentive Plan (the “2015 Plan”), the board of directors may issue incentive stock options, share equivalents such as restricted stock awards, stock bonus awards, performance shares and restricted stock units to employees and directors and non-qualified stock options to consultants of the company. Options generally expire ten years after being granted. Options granted vest in accordance with the vesting schedule determined by the board of directors, usually ratably over a three-year vesting schedule upon anniversary date of the grant with the first 1/3 vesting on the grant date. Should an employee terminate before the vesting period is completed, the unvested portion of each grant is forfeited. The Company have used the Black-Scholes valuation model to estimate fair value of our stock-based awards, which requires various judgmental assumptions including estimated stock price volatility, forfeiture rates, and expected life. The 2015 Plan reserves an aggregate of 6,000,000 shares. The number of unissued stock options authorized under the 2015 Plan at September 30, 2017 was 5,677,293.

The risk-free interest rate was based on the yield curve of a zero-coupon U.S. Treasury bond on the date the warrant was issued with a maturity equal to the expected term of the option. The fair values for the options granted were estimated at the date of grant using the Black Scholes option-pricing model with the following weighted average assumptions:
