4. | Capital Stock, Stock Plans and Stock Based Compensation
The Company has certain stock option plans under which it awards incentive and non-qualified stock options to employees, officers, and outside directors. No stock options were granted during the first six months of 2015 or 2014. As of June 30, 2015, the Company had an aggregate of 55,000 employee stock options outstanding (from the 2010 Stock Option Plans), of which none are vested. The weighted average exercise price of the 55,000 outstanding employee stock options is $5.00 with a remaining weighted contractual life of 5.0 years. Additionally, we had an aggregate of 166,635 outstanding director stock options (from the 2003 Outside Directors Stock Plans), of which all are vested. The weighted average exercise price of the 166,635 outstanding and fully vested director stock options is $8.88 with a remaining weighted contractual life of 4.6 years. The summary of the Company’s total Stock Option Plans as of June 30, 2015, and 2014, and changes during the periods then ended, are presented below. The Company’s Plans consist of the 2010 and 2004 Stock Option Plans and the 2003 Outside Directors Stock Plans:

(1) Options with exercise prices ranging from $2.79 to $14.75 The Company estimates the fair value of stock options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. The following table summarizes stock-based compensation recognized for the three and six months ended June 30, 2015 and 2014 for our employee and director stock options.

The Company recognized stock-based compensation expense using a straight-line amortization method over the requisite service period, which is the vesting period of the stock option grant. ASC 718, “Compensation – Stock Compensation” requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company has generally estimated forfeiture rates based on historical trends of actual forfeitures. When actual forfeitures vary from our estimates, the Company recognizes the difference in compensation expense in the period the actual forfeitures occur or when options vest. The total stock-based compensation expense for the six months ended June 30, 2014 included a reduction in expense of approximately $54,000 resulting from the forfeiture of options by Mr. Jim Blankenhorn, our Chief Operating Officer (“COO”), who voluntarily resigned from the Company effective March 28, 2014. The COO was granted an option from the Company’s 2010 Stock Option Plan on July 25, 2011, to purchase up to 60,000 shares of the Company’s Common Stock at $7.85 per share. The options had a six year contractual term with one-third yearly vesting over a three year period. As of June 30, 2015, the Company has approximately $99,000 of total unrecognized compensation cost related to unvested options, of which $27,000 is expected to be recognized in remaining 2015, $53,000 in 2016, with the remaining $19,000 in 2017. During the six months ended June 30, 2015, the Company issued a total of 33,910 shares of our Common Stock under our 2003 Plan to our outside directors as compensation for serving on our Board of Directors. Also, an outside director exercised 2,388 options from the 2003 Plan for the purchase of 2,388 shares of the Company’s Common Stock at $2.79 per share.
