All options and RSUs are expected to be settled by issuing new shares. (b) Options In 2019, 2020 and 2021, no options were exercised for each year. Our Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options granted to employees on the grant date. No options were granted to employees during 2019, 2020 and 2021. Option term. The expected term of the options granted represents the period of time that they are expected to be outstanding. Our Company estimates the expected term of options granted based on historical experience with grants and option exercises. Expected volatility rate. An analysis of historical volatility was used to develop the estimate of expected volatility. Risk-free interest rate. The risk-free interest rate is based on yields of U.S. Treasury bonds for the expected term of the options. Expected dividend yield. The dividend yield is based on our Company’s current dividend yield. Option transactions during the last three years are summarized as follows:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between GigaMedia’s closing stock price on the last trading day of 2021 and the exercise price of an option, multiplied by the number of in-the-money options) that would have been received by the option holders had they exercised their options on December 31, 2021. This amount changes based on the fair market value of GigaMedia’s stock. As of December 31, 2021, there was no unrecognized compensation cost related to non-vested options. The following table sets forth information about stock options outstanding at December 31, 2021:
