A summary of the stock option activity is presented below:
The following table summarizes information about stock options outstanding and exercisable under the Company’s Stock Option Plan at March 31, 2021:
The Company uses the Black-Scholes option pricing model to determine the estimated fair value of options. The fair value of each option grant is determined on the date of grant and the expense is recorded on a straight-line basis and is included as a component of general and administrative expense in the consolidated statements of operations. The assumptions used in the model include expected life, volatility, risk-free interest rate, dividend yield and forfeiture rate. The Company’s determination of these assumptions are outlined below.
Expected life — The expected life assumption is based on an analysis of the Company’s historical employee exercise patterns.
Volatility — Volatility is calculated using the historical volatility of the Company’s common stock for a term consistent with the expected life.
Risk-free interest rate — The risk-free interest rate assumption is based on the U.S. Treasury rate for issues with remaining terms similar to the expected life of the options.
Dividend yield — Expected dividend yield is calculated based on cash dividends declared by the Board for the previous four quarters and dividing that result by the average closing price of the Company’s common stock for the quarter. The Company has not declared a dividend to date.
Forfeiture rate — The Company does not estimate a forfeiture rate at the time of the grant due to the limited number of historical forfeitures. As a result, the forfeitures are recorded at the time the grant is forfeited.
