Represents the cumulative total shareholder return (on a dividends-reinvested basis) on our common stock from December 31, 2021, the last trading day before the earliest year presented in the table, to the last trading day of the relevant year, calculated on the basis of an investment of $100 in our common stock on December 31, 2021.

Represents compensation actually paid for 2024 to Brent C. Bruun, our chief executive officer during 2024, and the average compensation actually paid for 2024 to Felise B. Feingold, Anthony Pike, Roger A. Kuebel and Robert J. Balog, our other named executive officers for 2024. The employment of Messrs. Kuebel and Balog terminated in 2024, and the compensation actually paid to them includes severance compensation paid to them in 2024, including the acceleration of vesting of certain equity awards. The following table provides the adjustments to total compensation that were made in order to calculate compensation actually paid (excluding the grant-date fair value of equity awards granted in 2024, which is presented separately in the Summary Compensation Table):

​	Change in Fair Value	​	​	Mr. Bruun	​	​	Average for non-PEO NEOs	​
​	New Grants Unvested at Year-End	​	​	261,345	​	​	44,524	​
​	Prior Year Awards Unvested at Year-End	​	​	5,845	​	​	815	​
​	New Grants that Vested in 2024	​	​	—	​	​	—	​
​	Prior Year Awards that Vested in 2024	​	​	(19,082)	​	​	(34,399)	​
​	Prior Year Awards that Failed to Vest in 2024	​	​	—	​	​	—	​
​	Dividends or Earnings on Awards Before Vesting	​	​	—	​	​	—	​

Assumptions used in the calculation of fair values for this table that differed from the assumptions disclosed in the calculation of fair value as of the respective grant dates are: for option valuations as of December 31, 2023, a risk-free rate of 4.49%, volatility of 43.93%, an expected total life of 4.3 years (adjusted down based on time since grant), and the closing stock price on December 31, 2023; for option valuations during 2024, a risk-free rate of 4.36%, volatility of 48.63%, an expected total life of 4.32 years (adjusted down based on time since grant), and the closing stock price on, or in the case of weekend valuation dates immediately prior to, the valuation date; for RSAs, the closing stock price on, or in the case of weekend valuation dates immediately prior to, the valuation date. Assumptions used in the calculation of fair values of options for which vesting was accelerated on April 22, 2024 were a risk-free rate of 5.42%, volatility of 39.91%, an expected total life of 0.25 years, and the closing stock price on April 22, 2024.

- Definition

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
