Stock-Based Compensation [Abstract]

Stock-Based Compensation

12. Stock-Based Compensation

During the three and six months ended June 30, 2020, we granted restricted stock units (which we refer to as “RSUs”) covering 0.1 million and 0.4 million shares of common stock, respectively, with a grant date fair value of $27.64 and $30.44 per share, respectively, that vest over a three year period. During the three and six months ended June 30, 2020, we also granted performance share units (which we refer to as “PSUs”) covering up to 0.3 million shares of common stock, assuming maximum level of performance, with a grant date fair value of $26.38 per share that are subject to both service and performance vesting conditions. The quantity of shares that will vest under the PSUs ranges from 0% to 250% of a targeted number of shares for each participant and will be determined based on an achievement of a three year pre-tax income performance goal.

A summary of our outstanding RSUs and PSUs, assuming current estimated level of performance achievement, are as follows (in thousands, except years):

	As of June 30, 2020
Unvested units		1,435
Unrecognized compensation cost	$	22,151
Remaining period to recognize compensation cost		1.84 yrs

During the three months ended June 30, 2020 and 2019, we recognized stock-based compensation expense of $6.9 million and $3.9 million, respectively. During the six months ended June 30, 2020 and 2019, we recognized stock-based compensation expense of $8.6 million and $7.5 million, respectively. Stock-based compensation expense is included in selling, general, and administrative expense on our condensed consolidated statements of operations.

During the three months ended June 30, 2020, we updated our recognition of stock-based compensation expense associated with previously granted PSU awards to reflect probable financial results as they relate to the performance goals of the awards. Accordingly, our estimate of the number of shares which will ultimately vest under our PSU awards increased by 0.2 million, and we recorded a cumulative catch-up adjustment to increase stock-based compensation expense of $2.9 million ($2.2 million net of tax), or $0.07 per share (basic and diluted) for the three months ended June 30, 2020.
