Restricted Stock Units

 

Restricted stock units are awards that give the holder the right to receive one share of common stock for each restricted stock unit upon meeting service-based vesting conditions (typically annual vesting in three equal annual installments, with a requirement that the holder remains in the continuous employment of the Company). The value of restricted stock units that vest over time is established by the market price on the date of its grant. A summary of the Company’s restricted stock unit activity for the six months ended June 30, 2021 and 2020 is presented in the following table:
