The aggregate intrinsic value of options exercised during the years ended September 30, 2020 and 2019 was $640,000 and $864,000, respectively.

The Company uses the Black-Scholes option pricing model to estimate the fair value of stock-based awards with the weighted average assumptions noted in the following table. The risk-free interest rate is based on the rate of a U.S. Treasury security with a similar term as the expected life of the stock option at the particular grant date. The expected life is based on historical data, vesting terms and estimated exercise dates. The expected dividend yield is based on the most recent quarterly dividend on an annualized basis in effect at the time the options were granted, adjusted, if appropriate, for management's expectations regarding future dividends. The expected volatility is based on historical volatility of the Company’s stock price. There were 45,950 options granted during the year ended September 30, 2018 with an aggregate grant date fair value of $206,000. There were 46,840 options granted during the year ended September 30, 2019 with an aggregate grant date fair value of $240,000. There were 69,150 options granted during the year ended September 30, 2020 with an aggregate grant date fair value of $187,000.

Expected volatility	33		%	29		%	17		%
Expected life (in years)	5			5			5
Expected dividend yield	5.36		%	3.28		%	2.61		%
