Long-Term Incentive Plan
The 2021 Long-Term Incentive Plan (“2021 LTIP”) provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, bonus stock, and performance awards. The maximum aggregate number of shares of the Company’s common stock that may be issued under the 2021 LTIP is 22.1 million shares.

Stock Options
The exercise price of a stock option granted is equal to the fair value of the underlying stock on the date of the grant. Stock options granted under the LTIP have a contractual term of ten years and generally vest ratably over three years. To estimate the fair value of options granted, the Company uses the Black-Scholes option pricing model.
There were no stock options granted in the year ended December 31, 2025. The weighted-average assumptions used to value the stock options granted for the years ended December 31, 2024 and December 31, 2023 were as follows:
| | | | | | | | | | | | | | |
| |
| | 2024 | | 2023 |
| Weighted average grant date fair value | | $ | 76.21 | | | $ | 64.77 | |

Expected term (in years)(3) | | 5.4 | | 5.5 |
(1)Based on a weighting of the historical volatility and implied volatility.
(2)Based on a composite US Treasury rate.
(3)Based on contractual term length and on historical experience of both exercised and unexercised options.
