Share-based Payment Arrangement [Abstract] |
Stock Options | 14. Stock Options The Company adopted a stock option plan (“Plan”). The purpose of this Plan is to provide additional incentives to key employees, officers, directors and consultants of the Company and its subsidiaries in order to help attract and retain the best available personnel for positions of responsibility and otherwise promote the success of the Company’s business. It is intended that options issued under this Plan constitute non-qualified stock options. The general terms of awards under the option plan are that 100% of the options granted will vest the year following the grant. The maximum term of options granted is 5 years. The Company may issue stock options and stock bonuses for shares of its common stock to provide incentives to directors, key employees and other persons who contribute to the success of the Company. The exercise price of all incentive options are issued for not less than fair market value at the date of grant. The following table summarizes the Company’s stock option activity for the year ended December 31, 2017 and the three-month period ended March 31, 2019:
