Schedule of valuation assumptions

​		2022		2021
Valuation assumptions:					​
Expected dividend yield		—	%	—	%
Expected volatility		32	%	32	%
Expected term (years)(1)		5.6 – 6.2		5.0 – 6.1	​
Risk-free interest rate		2.76	%	1.14	%

(1) Our historical exercise behavior for previous grants does not provide a reasonable estimate for future exercise activity for employees who have been awarded stock options in the past three years. Therefore, the average expected term was calculated using the simplified method, as defined by GAAP, for estimating the expected term.
