Share-Based Payment Arrangement [Abstract] |
Share-Based Compensation | Share-Based Compensation Share-Based Incentive Plans The Company has established various plans under which it is authorized to grant restricted stock, restricted stock units, stock options, and stock appreciation rights. The Company may also grant cash awards that can be notionally invested in one or more specified measurement funds, including the Company’s common stock. Awards granted under the Company’s share- based incentive plans typically participate in any dividends declared, but such amounts are deferred until delivery of the shares and are forfeitable if the requisite service is not satisfied. Dividends may accrue in cash or may be reinvested in the Company’s common stock. Share-Based Compensation The following table presents share-based compensation expense:

The Company granted restricted stock units with fair values of $47.1 million, $49.3 million, and $31.3 million for the years ended December 31, 2022, 2023, and 2024, respectively. These restricted stock units were valued based on the closing price of the Company’s common stock on the grant date and the number of shares expected to vest. Restricted stock units containing vesting conditions generally require service over a period of three years to four years and may also require the satisfaction of certain performance conditions. For awards with performance conditions, the number of restricted stock units expected to vest may change over time depending upon the performance level expected to be achieved. The total fair value of shares vested was $54.6 million, $86.2 million, and $50.5 million for the years ended December 31, 2022, 2023, and 2024, respectively. As of December 31, 2024, the Company had 2.2 million shares available for grant under its plans. Stock Options The following table summarizes transactions in the Company’s stock options:

T he weighted average fair value of stock options granted was $47.84 per option for the year ended December 31, 2022.
