This fair value was estimated as of the grant date using the range of assumptions listed below:

 

		Three months ended December 31, 2019
Dividend yield			0%
Expected volatility		39.57	-	41.59%
Risk-free interest rate		1.65	-	1.69%
Expected life (years)		4	-	6
Vesting period (years)		3	-	5

 

The expected stock price volatility is based on the historical volatility of the Company’s stock for a period approximating the expected life. The expected life represents the period of time that options are expected to be outstanding after their grant date. The risk-free interest rate reflects the interest rate as of the grant date on -coupon U.S. governmental bonds having a remaining life similar to the expected option term.

 

Options are granted at fair market values determined on the date of grant and vesting normally occurs over a to -year period. Shares issued upon exercise of a stock option are issued from the Company’s authorized but unissued shares.
