Stock Option Plans and Restricted Stock Awards | 18. STOCK OPTION PLANS AND RESTRICTED STOCK AWARDS In May 2008, the shareholders approved the 2008 Equity Incentive Plan which authorizes the issuance of up to 3,949,891 shares of Company common stock for grants of stock options and restricted stock to employees, officers, consultants and directors of the Company and its subsidiaries, and expires in 2018. The plan authorizes the issuance of incentive and non-qualified stock options, as well as, restricted stock awards. The 2008 Equity Incentive Plan replaced the 2000 Stock Option Plan. No further grants will be made under the 2000 Stock Option Plan, but shares may continue to be issued under such plan pursuant to grants previously made. As of December 31, 2015, we have 166,710 outstanding options under our 2000 Stock Option Plan. Stock Options The Company expensed $549,000, $876,000 and $850,000, for the years ended December 31, 2015, 2014 and 2013, respectively. The estimated fair value of the options granted during 2015 and prior years was calculated using the Black-Scholes options pricing model. There were 83,000, 169,000 and 45,000 options granted during 2015, 2014 and 2013, respectively. The options will vest, in equal installments, over a five-year period. The fair value of each stock option granted in 2015, 2014 and 2013, was estimated on the date of grant using the following weighted-average assumptions.
|  | For the Year Ended December 31, |
|  | 2015 |  |  | 2014 |  |  | 2013 |
Dividend yield |  |  | 2.5 | % |  |  | 2.6 | % |  |  | 2.9 | %
Volatility |  |  | 47.7 | % |  |  | 50.3 | % |  |  | 50.5 | %
Risk-free interest rate |  |  | 1.5 | % |  |  | 1.5 | % |  |  | 1.2 | %
Expected life |  |  | 6.1 years |  |  |  | 6.3 years |  |  |  | 6.6 years |
Weighted average grant date fair value |  | $ | 5.83 |  |  | $ | 5.70 |  |  | $ | 4.68 |
The expected volatility is solely based on the daily historical stock price volatility over the expected option life. The expected life of options granted is derived from the output of the option valuation model and represents the period of time an optionee will hold an option before exercising it. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury five-year constant maturity yield curve in effect at the time of the grant. The Company estimates its forfeiture rates based on its historical experience. The forfeiture rate for 2015 was 6.0%. The following table presents option activity under the Company’s stock option plans as of and for the year ended December 31, 2015.
