The RSUs granted to all of our named executive officers in 2017 were subject to satisfaction of specified service-based and performance-based conditions. The performance objectives were subject to under- or over- achievement on a sliding scale, with a threshold of 50% of the target number of RSUs and a maximum of 150% of the target RSUs. In February 2019, our Compensation Committee determined actual achievement of the 2017 performance-based RSUs resulting in additional RSUs granted of approximately 29,000 at a grant-date fair value of $11.94 per share during the nine months ended September 30, 2019.
