Note 9 – Employee Benefit Plans

The Company maintains a 401(k) retirement plan that covers most of its employees. Under the plan, a full-time or regular part-time (over 20 hours/week) employee becomes a participant after completing six months of employment. Employees may elect to contribute up to 50 percent of regular gross pay, subject to federal law limits on the dollar amount that participants may contribute to the plan, each calendar year. The Company matches part of the employee contributions and may make a discretionary contribution to the plan. Total employer contributions were approximately $0.5 million for the year ended December 31, 2012, $0.4 million for the year ended December 31, 2011 and $0.3 million for the year ended December 31, 2010.
