Schedule of Stock Options Valuation Assumptions

The weighted average grant date fair value of stock options granted during the year ended December 31, 2019 was $9.41. Key weighted-average assumptions utilized in the Black-Scholes Option Pricing Model for stock options granted during the year ended December 31, 2019 were:

Risk-free interest rate	2.27	%
Expected volatility (a)	31.44	%
Expected dividend yield	0.00	%
Expected life (years) (b)	6.00

(a) ^{Prior to April 2019, due to the Company’s limited history as a public company, the volatility for the Company’s stock was estimated using the average volatility calculated for a peer group, which was based upon daily price observations over the estimated term of options granted.}

(b) The expected life was estimated using the simplified method, as the Company does not have sufficient historical exercise data due to the limited period of time its common stock has been publicly traded.
