We have stock award plans for key employees and directors, pursuant to which awards of stock options, SSARs, restricted stock, restricted stock units, and performance stock units are granted. In addition, we offer an employee stock purchase plan to employees.

During the three months ended March 31, 2022, we granted awards of 135,381 restricted stock units and 88,239 performance stock units, at an average grant date fair value of $70.55 per share.
We recognized $7 million and $1 million in stock-based compensation expense during the three months ended March 31, 2022 and 2021, respectively. At March 31, 2022, there was $36 million of unrecognized stock-based compensation expense related to unvested performance stock units, restricted stock units, and SSARs attributable to future service.
