Schedule of Key Valuation Assumptions Used in Valuation

The fair value of the TSR Units is estimated on the date of the grant using a Monte Carlo valuation model. The risk-free rate is based on the U.S. Treasury yield curve in effect at the grant date for the expected performance period. Expected volatility is based on historical volatility for the most recent weighted average period ending on the grant date for the Company and the selected TSR peer group, and is calculated on a daily basis. The following table reflects the weighted-average key assumptions used in this valuation for awards granted during the year ended December 31, 2022 and 2021:

	For the Year Ended December 31, 2022			For the Year Ended December 31, 2021
Risk-free interest rate	3.91		%	0.60		%
Expected stock price volatility	52.90		%	52.42		%
Expected service period	3.04 years			2.93 years
Expected dividend yield (assuming full reinvestment)	—		%	—		%
Fair value per share at date of grant	$	26.53		$	29.10
