Equity Instruments | Note 6—Equity Instruments Options In 2010, Ampio shareholders approved the adoption of a stock and option award plan (the “2010 Plan”), under which shares were reserved for future issuance under restricted stock awards, options, and other equity awards. The 2010 Plan permits grants of equity awards to employees, directors and consultants. The shareholders have approved a total of 11.7 million shares reserved for issuance under the 2010 plan. Ampio has computed the fair value of all options granted using the Black-Scholes option pricing model. In order to calculate the fair value of the options, certain assumptions are made regarding components of the model, including the estimated fair value of the underlying common stock, risk-free interest rate, volatility, expected dividend yield and expected option life. Changes to the assumptions could cause significant adjustments to valuation. Ampio calculates its volatility assumption using the actual changes in the market value of its stock. Ampio has estimated a forfeiture rate of 5.3% based upon historical experience; this is an estimate of options granted that are expected to be forfeited or cancelled before becoming fully vested. Ampio estimates the expected term based on the average of the vesting term and the contractual term of the options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity. During the six months ended June 30, 2016, Ampio granted 5,000 options at a price of $6.53 to a former employee to replace 5,000 options that were forfeited due to the spin-off of Aytu. The $6.53 price represented the fair market value on the original date of the grant and was above Ampio’s stock price on the date when the option was re-granted in 2016. On June 30, 2016, the Company cancelled 470,000 performance based options that were based on the outcome of the most recent Ampion trial. As the awards were performance based, no expense was previously recognized on these options. Ampio has computed the fair value of all options granted during the six months ended June 30, 2016 using the following assumptions: Expected volatility 124% Risk free interest rate 0.61% Expected term (years) 1.0 Dividend yield 0.0% Forfeiture rate 5.3% Ampio stock option activity is as follows: Number of Weighted Weighted Average Outstanding December 31, 2015 7,315,832 $ 3.71 6.58 Granted 5,000 $ 6.53 Exercised - $ - Forfeited - $ - Expired or Cancelled (475,000) $ 2.67 Outstanding June 30, 2016 6,845,832 $ 3.78 5.23 Exercisable at June 30, 2016 6,490,935 $ 3.77 5.04 Available for grant at June 30, 2016 3,441,647 Stock options outstanding and exercisable at June 30, 2016 are summarized in the table below: Range of Exercise Prices Number of Weighted Weighted Average $1.03 - $4.00 4,670,832 $ 2.35 4.91 $4.01 - $7.00 1,240,000 $ 6.17 5.39 $7.01 - $8.93 935,000 $ 7.73 6.58 6,845,832 $ 3.78 5.23 Stock-based compensation expense related to the fair value of stock options was included in the statements of operations as research and development expenses and general and administrative expenses as set forth in the table below. Ampio determined the fair value as of the date of grant using the Black-Scholes option pricing model and expenses the fair value ratably over the vesting period. The following table summarizes stock-based compensation expense for the three and six months ended June 30, 2016 and 2015: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Research and development expenses Stock options $ 65,000 $ 449,000 $ 155,000 $ 1,057,000 General and administrative expenses Common stock issued for services - - 60,000 30,000 Stock options 208,000 1,192,000 728,000 1,729,000 $ 273,000 $ 1,641,000 $ 943,000 $ 2,816,000 Unrecognized expense at June 30, 2016 $ 555,407 Weighted average remaining years to vest 0.83 Warrants Ampio issued warrants in conjunction with its senior convertible debentures, 2011 private placements and an underwritten public offering.
