Compensation and Employee Benefit Plans
Employee Benefit Plans

The Company sponsors a defined contribution plan. This plan covers employees who are at least 18 years of age and have completed a 6-month time period of employment. Employees are eligible to participate in the plan on the first day of the plan year month coinciding with the date in which the employee satisfies the eligibility requirements. The plan provides for the option of employee contributions up to statutory limits, of which we match up to 4% of the employees contributions, at a rate of 100% on the first 3% and 50% on the next 2%. Company contributions to the plan totaled approximately $1.0 million for each of the years ended December 31, 2017, 2016, and 2015.
