EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS 401(k) Benefit Plan We maintain a plan qualified under Section 401(k) of the Internal Revenue Code for all employees who have reached 21 years of age, effective the first month after hire date. Under the plan, eligible employees may elect to defer a portion of their compensation, subject to Internal Revenue Service limits. Effective January 1, 2017, our match of contributions to be made to each eligible employee contribution is $0.44 for every $1.00 contributed up to the first 6% of their salary. During 2016, our match of contributions to be made to each eligible employee contribution was $0.375 for every $1.00 contributed up to the first 6% of their salary. The match is discretionary and thus is subject to change at the discretion of management. These contributions are made in the form of our common stock, valued based upon the fair value of the stock as of the end of each calendar quarter end.

Deferred Compensation Plan We had a Deferred Compensation Plan for additional tax-deferred savings for a select group of management or highly compensated employees. Amounts credited under the Deferred Compensation Plan were funded into a rabbi trust, which is managed by a trustee.
