Employee Benefit Plan [Abstract]

Employee Benefit Plan

N. Employee Benefit Plan

We have a defined contribution plan under Section 401(k) of the Internal Revenue Code to provide retirement and profit sharing benefits covering substantially all full-time employees. Employees are eligible to contribute up to 100% of their gross salary until they reach the maximum annual contribution amount allowed under the Internal Revenue Code. We match $0.50 for every $1.00 contributed by an employee up to 6% of the employee’s salary; the maximum match is 3%. Vesting of our contributions is over a five-year period at 20% per year. Our payments on behalf of the defined contribution plan were $115,000, $96,000 and $96,000 in the years ended December 31, 2012, 2011 and 2010 respectively.
