During the six months endedJune 30, 2015, the Company granted 197,408 stock options with an exercise price equal to the closing market price of a share of Common Stock on the date of grant. The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model, which resulted in a weighted average grant date fair value per share of $6.19.
