12. Employee Benefit Plans

The Company sponsors a 401(k) employee savings plan which covers substantially all employees. Employees can contribute up to 15% of their gross income to the plan. The Company matched a percentage of the employee’s contribution at a rate of 10% for the years ended December 31, 2016, and 2015, respectively. Company contributions under the 401(k) plan totaled $44,200 and $49,300 in 2016 and 2015, respectively.

On September 1, 2006, the Company established an employee stock ownership plan ("ESOP") which covers substantially all U.S. employees. Contributions to the ESOP are funded by the Company on a discretionary basis. In 2016 and 2015, the Company did not make any contributions to the ESOP.
