Long-Term Incentive Plan (the “Plan”). Under the Plan, the Company’s employees are eligible to be granted stock options, restricted stock awards (“RSAs”), restricted stock units (“RSUs”), and performance stock awards (“PSAs”). For the nine months ended September 30, 2019, the Company granted 521,157 stock options with a weighted average fair value of $6.02 per share and 256,382 shares of RSAs and RSUs with a weighted average fair value of $14.99 per share.
