The following table summarizes the inputs to the option valuation model for the options granted during the years ended December 31, 2018 and 2017:

The Company bases expected volatility on the weighted average historical stock volatility of the Company's common stock. There is no dividend rate, as dividends are not expected to be paid. The expected term utilizes historical data to estimate the period of time that the options are expected to remain unexercised. The Company bases risk-free rates on the U.S. Treasury zero-coupon rates with a remaining term equal to the expected term of the option. The Company records any forfeitures in the period that the shares are forfeited.
