3. Stock-Based Compensation |
At March 31, 2016, the Company had two stock-based compensation plans described in Note 9 of the Annual Report. Total compensation expense related to these plans was $666 and $2,871 for the quarters ended March 31, 2016 and 2015, respectively, none of which related to options awarded to non-employees. 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 ended March 31, 2016 and 2015, were estimated using the Black-Scholes option pricing model using the following assumptions:
The status of the options issued as of March 31, 2016 and changes during the three months ended March 31, 2016 and 2015 were as follows:
