Stock-Based Compensation | 16. Stock-Based Compensation During the years ended December 31, 2020, 2019, and 2018, we granted performance share units (which we refer to as “PSUs”) covering up to 0.3 million shares of common stock in each year, assuming maximum level of performance, with grant date fair values of $26.38, $22.01, and $28.10, respectively, per share that are subject to both service and performance vesting conditions. The quantity of shares that will vest under the PSUs range from 0% to 250% of a targeted number of shares for each participant and will be determined based on an achievement of a 3 year pre-tax income performance goal. During the years ended December 31, 2020, 2019 and 2018, we also granted restricted stock units (which we refer to as “RSUs”) covering 0.4 million, 0.6 million and 0.3 million shares of common stock, respectively, with grant date fair values of $30.44, $23.85 and $30.43 per share, respectively, that vest over a 1 to 3 year period. Prior to 2017, we had granted restricted stock awards (“RSAs”) which fully vested during the year ended December 31, 2018. The following table summarizes the activity of our PSUs, RSUs, and RSAs for the years ended December 31, 2020, 2019 and 2018 (in thousands):
A summary of our outstanding RSUs and PSUs, assuming current estimated level of performance achievement, are as follows (in thousands, except years):
