Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | ## 17. STOCK-BASED COMPENSATION PLANS At December 31, 2014, the Company had three stock-based compensation plans: the 2005 Equity Incentive Plan, the 2011 Incentive Plan and the 2014 Incentive Plan (collectively, “the Plans”). Under the Plans, options to purchase common stock were granted to officers and key employees at exercise prices not less than the fair market value of the Company’s common stock on the date of the grant. The Company issues new common stock to satisfy stock option exercises and the issuance of restricted stock awards. Awards are no longer granted under the 2005 and 2011 plans. Stock options and restricted stock awards were granted on August 26, 2014, December 2, 2013, and on December 1, 2012. Under the 2011 and 2014 Incentive Plans, stock options and restricted stock awards are valued at fair market value based on the Company’s closing stock price on the date of grant. Under 2005 plan, stock options were valued at fair market value based on the average of the Company’s high and low trade prices on the date of grant. The stock options and restricted stock awards granted in 2014, 2013 and 2012 vest ratably over four years. Stock options granted between 2014 and 2011 expire six years from the date of grant. Stock options granted between 2006 and 2010 expire five years from the date of grant. Stock options granted prior to 2006 expire ten years from the grant date, with the exception of certain incentive stock options, which expired five years from the date of grant. As of December 31, 2014, there were 643,400 shares remaining available for stock-based awards under the 2014 Incentive Plan. In accordance with ASC 718, stock-based compensation expense was recognized in the 2014, 2013 and 2012 consolidated financial statements for stock options and restricted stock awards granted since 2008. An estimate of forfeitures, based on historical data, was included in the calculation of stock-based compensation, and the estimate was adjusted quarterly to the extent that actual forfeitures differ, or are expected to materially differ, from such estimates. The effect of applying the expense recognition provisions of ASC 718 in 2014, 2013 and 2012 decreased Earnings Before Provision For Income Taxes by approximately $1,465,000, $1,283,000 and $1,201,000, respectively. As of December 31, 2014, there was $2.1 million of total unrecognized compensation cost related to non-vested stock options granted in the years 2011 through 2014 which is expected to be recognized over the weighted-average remaining vesting period of 2.8 years. As of December 31, 2014, there was $1.3 million of total unrecognized compensation cost related to non-vested restricted stock awards granted in the years 2011 through 2014 which is expected to be recognized over the weighted-average remaining vesting period of 2.9 years. The following weighted-average assumptions were used to determine compensation expense related to stock options in 2014, 2013 and 2012:
|  | 2014 |  | 2013 |  | 2012
Risk-free interest rate |  |  | 1.45 | % |  |  | 1.10 | % |  |  | 0.51 | %
Expected dividend yield |  |  | 2.81 | % |  |  | 2.53 | % |  |  | 2.89 | %
Expected term |  |  | 4.3 years |  |  |  | 4.3 years |  |  |  | 4.3 years |
Expected volatility |  |  | 17.8 | % |  |  | 16.2 | % |  |  | 26.4 | %
The risk-free interest rate is based on U.S. Treasury bonds with a remaining term equal to the expected term of the award. The expected dividend yield is based on the Company’s expected annual dividend as a percentage of the market value of the Company’s common stock in the year of grant. The expected term of the stock options is determined using historical experience. The expected volatility is based upon historical stock prices over the most recent period equal to the expected term of the award.
