Employee benefit plan

11. Employee benefit plan

The Company has a defined contribution profit sharing 401(k) plan (the “Plan”) for eligible employees, which is qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended. Employees are entitled to make tax-deferred contributions of up to the maximum allowed by law of their eligible compensation, but not exceeding $17,000. The Company currently matches 100% of the first 3% of eligible compensation contributed to the Plan by each participant and 50% of the next 2% of eligible compensation contributed to the plan by each participant. Beginning January 1, 2008, the Company’s matching contributions are immediately vested. The Company’s matching contributions to the Plan for the three months ended March 31, 2012 and 2011, were approximately $136,000 and $125,000, respectively. Future matching or profit sharing contributions to the Plan are at the Company’s sole discretion.
