( 11 ) | Stock Option and Equity Incentive Plans
Share-based compensation is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period (generally the vesting period of the equity grant). The Company issues share-based awards through several plans that are described below. The compensation cost charged against income for those plans is included in selling, general & administrative expenses as follows (in thousands):

Incentive Plan In June 2003, the Company formally adopted the 2003 Incentive Plan (the “Plan”). The Plan was originally intended to benefit the Company by offering equity-based incentives to certain of the Company’s executives and employees, thereby giving them a permanent stake in the growth and long-term success of the Company and encouraging the continuance of their involvement with the Company’s businesses. The Plan was amended effective June 4, 2008, to permit certain performance-based cash awards to be made under the Plan. The Plan was further amended on June 8, 2011, to increase the maximum number of shares of common stock in the aggregate to be issued to 2,250,000. The amendment also added appropriate language so as to enable grants of stock-based awards under the Plan to continue to be eligible for exclusion from the $1,000,000 limitation on deductibility under Section 162 (m) of the Internal Revenue Code (the “Code”). The Plan was further amended on March 7, 2013, to (i) prohibit the repricing of stock options or other equity awards without the consent of the Company’s shareholders, and (ii) prohibit the Company from buying out underwater stock options. Two types of equity awards may be granted to participants under the Plan: restricted shares or other stock awards. Restricted shares are shares of common stock awarded subject to restrictions and to possible forfeiture upon the occurrence of specified events. Other stock awards are awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of common stock. Such awards may include Restricted Stock Unit Awards (“RSUs”), unrestricted or restricted stock, incentive and non-qualified stock options, performance shares, or stock appreciation rights. The Company determines the form, terms, and conditions, if any, of any awards made under the Plan. Through December 31, 2017, 1,213,764 shares of common stock have been issued under the 2003 Incentive Plan, none of which have been restricted. An additional 56,902 shares are being reserved for outstanding grants of RSUs and other share-based compensation that are subject to various performance and time-vesting contingencies. The Company has also granted awards in the form of stock options under this Plan. Through December 31, 2017, 185,000 options have been granted and 94,375 options are outstanding. At December 31, 2017, 893,615 shares or options are available for future issuance in the 2003 Incentive Plan. Director Plan Effective July 15, 1998, the Company adopted the 1998 Director Plan, which was amended and renamed, on June 3, 2009, the 2009 Non-Employee Director Stock Incentive Plan (the “Director Plan”). The Director Plan was amended on March 7, 2013, to (i) prohibit the repricing of stock options or other equity awards without the consent of the Company’s shareholders, and (ii) prohibit the Company from buying out underwater stock options. The Director Plan, as amended, provides for the issuance of stock options and other equity-based securities of up to 975,000 shares to non-employee members of the Company’s board of directors. Through December 31, 2017, 338,146 options have been granted and 129,879 options are outstanding. For the year ended December 31, 2017, 3,882 shares of common stock were issued and 115,336 shares remained available to be issued under the Director Plan. The following is a summary of stock option activity under all plans:

During the years ended December 31, 2017, 2016 and 2015, the total intrinsic value of all options exercised (i.e., the difference between the market price and the price paid by the employees to exercise the options) was approximately $0.6 million, $0.7 million and $1.3 million, respectively, and the total amount of consideration received from the exercise of these options was approximately $0.8 million, $0.7 million and $0.4 million, respectively. At its discretion, the Company allows option holders to surrender previously-owned common stock in lieu of paying the exercise price and withholding taxes. During the year ended December 31, 2017, 6,511 shares ( 6,511 for options and zero for taxes) were surrendered at an average market price of $26.45. During the year ended December 31, 2016, 6,514 shares ( 6,514 for options and zero for taxes) were surrendered at an average market price of $25.50. During the year ended December 31, 2015, 1,632 shares ( 1,632 for options and zero for taxes) were surrendered at an average market price of $21.97. On February 21, 2017, the Company’s Compensation Committee approved the award of $400,000 payable in shares of the Company’s common stock to the Company’s Chairman, Chief Executive Officer, and President under the 2003 Equity Incentive Plan. The shares were issued on December 19, 2017. On June 6, 2017, the Company issued 12,336 shares of unrestricted common stock to the non-employee members of the Company’s Board of Directors as part of their annual retainer for serving on the Board. The Company grants RSUs to its executive officers. The stock unit awards are subject to various time-based vesting requirements, and certain portions of these awards are subject to performance criteria of the Company. Compensation expense on these awards is recorded based on the fair value of the award at the date of grant, which is equal to the Company’s closing stock price, and is charged, to expense ratably during the service period. No compensation expense is taken on awards that do not become vested, and the amount of compensation expense recorded is adjusted based on management’s determination of the probability that these awards will become vested. The following table summarizes information about stock unit award activity during the year ended December 31, 2017:
|  | Restricted Stock Units |  | Weighted Average Award Date Fair Value
Outstanding at December 31, 2016 |  |  | 46,558 |  |  | $ | 20.05 |
Awarded |  |  | 24,256 |  |  |  | 24.87 |
Shares vested |  |  | (13,419 | ) |  |  | 23.54 |
Outstanding at December 31, 2017 |  |  | 57,395 |  |  | $ | 21.03 |
At the Company’s discretion, RSU holders are given the option to net-share settle to cover the required minimum withholding tax, and the remaining amount is converted into the equivalent number of common shares. During the year ended December 31, 2017, 4,377 shares were redeemed for this purpose at an average market price of $24.50. During the years ended December 31, 2016 and 2015, 3,389 and 3,405 shares were redeemed for this purpose at an average market price of $22.82 and $23.15, respectively. The following summarizes the future share-based compensation expense the Company will record as the equity securities granted through December 31, 2017, vest (in thousands):
|  | Options |  | Common Stock |  | Restricted Stock Units |  | Total
2018 |  |  | 44 |  |  |  | - |  |  |  | 370 |  |  |  | 414 |
2019 |  |  | 28 |  |  |  | - |  |  |  | 274 |  |  |  | 302 |
2020 |  |  | 28 |  |  |  | - |  |  |  | 187 |  |  |  | 215 |
2021 |  |  | - |  |  |  | - |  |  |  | 21 |  |  |  | 21 |
Total |  |  | 100 |  |  |  | - |  |  |  | 852 |  |  |  | 952 |
Tax benefits totaling approximately $0, $145,000, and $356,000 were recognized as additional paid-in capital during the years ended December 31, 2017, 2016 and 2015, respectively, since the Company’s tax deductions exceeded the share-based compensation charge recognized for stock options exercised and RSUs vested.
