Stock Options Stock Options granted by the Company generally expire between 5 to 10 years from the grant date and generally vest over a 1 to 3 year service period commencing on the grant date. The Company used the modified Black-Scholes model to estimate the fair value of employee Stock Options on the date of grant utilizing the assumptions noted below. The risk-free rate is based on the U.S. Treasury bill yield curve in effect at the time of grant for the expected term of the option. The expected term of options granted represents the period of time that the options are expected to be outstanding. Expected volatilities are based on historical volatilities of our Common Stock. The dividend yield was based on expected dividends at the time of grant. The following table provides the assumptions utilized in the Black-Scholes model for Stock Options granted during the periods presented:
|  | Years Ended December 31, |
|  | 2017 |  |  | 2016 |  |  | 2015 |
Weighted-average risk-free interest rate |  |  | 1.94 | % |  |  | 1.40 | % |  |  | 0.54 | %
Expected term of option in years |  |  | 5.84 |  |  |  | 5.44 |  |  |  | 3.38 |
Weighted-average volatility |  |  | 45.1 | % |  |  | 45.2 | % |  |  | 44.3 | %
Dividend yield |  |  | 2.0 | % |  |  | 3.4 | % |  |  | 3.4 | %
Weighted average grant date fair value per share |  | $ | 10.18 |  |  | $ | 6.01 |  |  | $ | 6.34 |
Restricted Stock Grants Restricted Stock grants are awarded to certain employees in consideration for services rendered pursuant to terms of employment agreements and or to provide to those employees with a continued incentive to share in the success of the Company. Restricted Stock generally vests over a three year service period commencing on the grant date. Performance Share Units PSUs are awarded to certain employees in consideration for services rendered pursuant to terms of employment agreements and provide those employees with a continued incentive to share in the success of the Company. Each performance share unit has a value equal to one share of common stock and generally vests over a three year service period commencing on the grant date.
