Share-based Compensation

Share-based Compensation

During the nine months ended September 30, 2022, we granted 0.03 stock options, 0.05 restricted stock units and 0.01 performance units. The total fair value of awards granted to employees during the nine months ended September 30, 2022 was $12.6. In addition, our non-employee directors received stock awards with a total fair value of $0.6. During the nine months ended September 30, 2022, participants in our stock option plans exercised options to purchase 0.03 shares of our common stock.

Stock options generally have a four-year graded vesting period. Restricted stock and restricted stock units generally vest ratably over a three-year period. Performance units generally vest at the end of a three-year performance period based on the attainment of certain pre-determined performance condition targets. During the nine months ended September 30, 2022, 0.06 restricted stock and restricted stock units vested and 0.02 performance units vested.

Share-based compensation expense was $2.3 and $2.3 for the three months ended September 30, 2022 and 2021, respectively and $7.9 and $8.1 for the nine months ended September 30, 2022 and 2021, respectively. Share-based compensation expense is included in selling, general, and administrative expenses in the unaudited condensed consolidated statements of income and comprehensive income. As of September 30, 2022, total share-based compensation of $14.1 is expected to be recognized over the weighted-average period of approximately 2.2 years.
