These options have a term of 10 years, vest equally over 3 years, 1/3 upon each anniversary of the grant date, and have an exercise price of $48.75 per share.

As of December 31, 2022 and 2021, there were 42 unvested restricted stock awards outstanding, with a weighted average grant date price of $235.87. The awards were issued in 2014 and vest over the lesser of ten years, a change in control, or separation from the company. Due to the variability of the vesting, the expense was amortized over an average service period of five years; therefore, there is no stock-based compensation expense for restricted stock awards for the years ended December 31, 2022 and 2021.
