3. Stock-Based Compensation | At September 30, 2015, the Company had two stock-based compensation plans described in Note 9 of the Annual Report. Total compensation expense related to these plans was $2,112 and $3,262 for the quarters ended September 30, 2015 and 2014, respectively, none of which related to options awarded to non-employees. Total compensation expense related to these plans was $7,826 and $12,067 for the nine months ended September 30, 2015 and 2014, respectively. The Company estimates the fair value of options granted using a Black-Scholes valuation model to establish the expense. When stock-based compensation is awarded to employees, the expense is recognized ratably over the vesting period. When stock-based compensation is awarded to non-employees, the expense is recognized over the period of performance. The fair values of option awards granted in the three months and nine months ended September 30, 2015 and 2014, were estimated using the Black-Scholes option pricing model using the following assumptions: Three Months ended September 30, Nine Months ended September 30, 2015 2014 2015 2014 Risk free interest rate n/a 1.78% 1.61 - 1.97% 1.77-1.78% Dividend yield n/a 0% 0% 0% Expected term n/a 5 years 5-10 years 5 years Expected volatility n/a 43.3% 41.2 - 54.2% 43.3 - 47.3% The status of the options issued as of September 30, 2015 and changes during the nine months ended September 30, 2015 and 2014 were as follows: Options outstanding Number of shares Weighted average exercise price per share Balance at December 31, 2014 1,264,000 $ 0.26 Options granted 20,000 0.20 Options exercised -- -- Options expired or forfeited (1,000 ) 0.24 Balance at March 31, 2015 1,283,000 $ 0.26 Options granted -- -- Options exercised -- -- Options expired or forfeited (5,000 ) 0.52 Balance at June 30, 2015 1,278,000 $ 0.25 Options granted -- -- Options exercised -- -- Options expired or forfeited (10,000 ) 0.38 Balance at September 30, 2015 1,268,000 $ 0.25 Options outstanding Number of shares Weighted average exercise price per share Balance at December 31, 2013 1,187,000 $ 0.26 Options granted -- -- Options exercised -- -- Options expired or forfeited -- -- Balance at March 31, 2014 1,187,000 $ 0.26 Options granted 1,000 0.24 Options exercised -- -- Options expired or forfeited (3,000 ) 0.11 Balance at June 30, 2014 1,185,000 $ 0.26 Options granted 20,000 0.17 Options exercised -- -- Options expired or forfeited -- -- Balance at September 30, 2014 1,205,000 $ 0.26 The following table summarizes information about options at September 30, 2015: Options outstanding Options exercisable Total shares Weighted average exercise price Weighted average remaining contractual life in years Aggregate intrinsic value Total shares Weighted average exercise price Weighted average remaining contractual life in years Aggregate intrinsic value 1,268,000 $ 0.25 4.92 $ 11,968 1,090,500 $ 0.27 4.33 $ 8,776 Nonvested stock awards as of September 30, 2015 and changes during the nine months ended September 30, 2015 were as follows: Nonvested Number of shares Weighted average grant date fair value Balance at December 31, 2014 209,500 $ 0.07 Granted 20,000 0.11 Vested (5,000 ) 0.08 Expired before vesting (1,000 ) 0.10 Balance at March 31, 2015 223,500 $ 0.08 Granted -- -- Vested (10,000 ) 0.09 Expired before vesting -- -- Balance at June 30, 2015 213,500 $ 0.07 Granted -- -- Vested (36,000 ) 0.09 Expired before vesting -- -- Balance at September 30, 2015 177,500 $ 0.07 As of September 30, 2015 and 2014, unrecognized compensation cost associated with non-vested share-based compensation totaled $1,846 and $6,156, respectively, which are expected to be recognized over weighted average periods of six months and seven months, respectively. |
