Restricted Stock Units
 
The Company issues time-based restricted stock units (“RSUs”) and performance-based restricted stock units ("PSUs") to employees and non-employee service providers. Each RSU and PSU represents the right to receive one share of the Company’s common stock upon vesting and subsequent settlement. PSUs vest upon achievement of performance targets based on the Company's annual operating plan.

The fair values of RSUs and PSUs are determined based on the closing price of the Company’s common stock on the date of grant.
 
Combined RSU and PSU activity for the six months ended June 30, 2021 is summarized below:
